Description

WALL MODULE FOR BUILDING A STRUCTURE AND ASSOCIATED STRUCTURE}

The present invention relates to a wall module for building a building, formed as a concrete prefabricated building element. The invention also relates to the construction of buildings, especially nuclear power plants, or plant buildings manufactured using such wall modules.

For example, safety-related nuclear plant buildings, such as buildings to house emergency power devices, have so far been implemented as concrete structures cast in the field with almost no exception. The prefabricated construction methods tested in conventional residential building construction have not been practically applied until now.

The high level of safety conditions raised for load situations EVI (action from inside) and EVA (action from outside) for nuclear plants and consideration of such load situations typically result in very high reinforcement densities. For this reason, most building structures in nuclear power plants or other nuclear technology plants are implemented in a massive building manner. In this type of construction, the minimum wall thickness has been about 0.85 m so far, due to the high reinforcement.

In other words, the building / architecture must withstand all loads and load combinations of the results of category H1-H4 as follows:

in normal operation( H1 ):

Permanent load

-Variable loads, including those caused by transport and installation work;

Combined load

The effects of individual events originating from the outside ( H2 ):

- explosion

-Crash of an airplane

-Fire in the outer zone;

The effects of unforeseen internal events ( H3 ):

-Fire in internal operation;

-Collapse of the internal design

-Down load

Internal flood

-Internal explosion

Events that are unlikely to occur ( H4 ):

- Earthquake

-Extreme wind

-Extreme snow and freezing

-Effect of tornado load, tornado-bullet

-Extreme external temperatures

Outside flood

-Extreme sedimentation

-Substance protection

Explosive Compression Waves

Explosive gas cloud

In this context, the use of prefabricated building elements has, in fact, been considered to be desirable due to the standardization and optimization of the overall design, construction and building sequence in connection therewith, thus far encountered significant difficulties and has not been implemented thereby. The reason for this is particularly the connection technology that has conventionally been used in prefabricated construction, which is not generally suitable for meeting various requirements raised in the nuclear field or for overcoming acceptable building element tolerances. .

The fact that new buildings with the same functions are actually built for each nuclear power plant allows us to think about how much design and implementation costs can be reduced.

This cost savings is made possible by a system that allows for flexible design of the desired space and the filling of the space using prefabricated modules.

The requirements raised for the construction of the nuclear power plant sector correspond to the highest requirements of construction- and safety technology. As a result, design and implementation are very complex and cost intensive.

The introduction of prefabricated building element construction methods has hitherto faced many difficulties related to the coercion of individual components, overcoming the associated tolerances and measurement inaccuracies, and the alignment inaccuracies in assembly.

The object of the present invention is therefore to assemble and connect with additional wall modules of the same type in a simple manner to form one building, in particular one building or building complex, designed for normal operating loads. And even extreme loads, which are rarely more likely to occur, such as floods, earthquakes, prolonged heavy rain, ice loads, wind loads, cyclones, extreme ambient temperatures, bullet impacts, plane crashes, etc.-individually Or a fully assembled-providing a wall module of the type mentioned in the preface.

The problem is solved by the features of the independent claim 1 according to the invention.

According to the invention, the wall module for building a building, formed as a concrete prefabricated building element, has a regular, in particular rectangular base area and a wall body having a plurality of, in particular four edges, A plurality of reinforcing rods forming a regular reinforcement grid as a whole and preferably each extending parallel to the edges and cast inside the wall body, in which case the reinforcing rods Each of the bodies actually penetrates from edge to edge and has a connecting member at its end, the connecting member being formed for the purpose of making a connection with a complementary connecting member of a directly neighboring wall module, in which case the Each connecting member-at least in the unconnected state with no complementary connecting members In-connected at intervals or movably in relation to the associated reinforcing rods to be able to move at least 2 mm on all sides with respect to a previously provided central position in a plane perpendicular to the longitudinal direction of the reinforcement rods. In a tightly coupled and fixed state, this possibility of movement can be reliably prevented.

Particular preference is given to ensuring a mobility of at least 5 mm, preferably up to about 10 mm, as well as sufficient for the typical requirements raised in the construction of nuclear power plants.

The term "wall module" in this application can be broadly defined and includes not only the inner- and outer wall sections (side walls) of a building, in particular floor- and ceiling plates.

Although flat wall modules of the same height as the ground with a rectangular bottom face are preferred, such wall modules may also be formed in a bent form, resulting in, for example, curved wall sections or cylindrical buildings (such as nuclear reactor buildings, etc.). ) Construction is possible.

As can be seen from the surprising facts, this approach not only allows flexible connections between individual modules that overcome building element tolerances and alignment tolerances that are unavoidable during on-site assembly, but also allows for proper dimensional design. In spite of the relatively high flexibility of the individual connections-or because of this relatively high flexibility-a wall module assembly capable of withstanding high loads can be realized, such wall module assemblies having high shear forces and bending rates. It withstands modulus and ensures reliable load removal into individual anchoring points beyond module limits.

It is preferable if the connecting member-at least primarily-is designed for mutually cohesive connection, in particular by screwing or tightening. In some cases, in particular, a shape engaging portion may be further provided for the purpose of protecting the pre-fabricated screw engaging portion.

In a preferred embodiment, at least two reinforcing rods, each extending in parallel, are integrated into one unit and connected to the same connecting member at the end side.

As already mentioned above, the individual wall modules may be components of side walls or ceiling walls or floor plates, more specifically aligned vertically or horizontally. Correspondingly, in the mounted or assembled state, not only for connecting the side wall modules and the ceiling wall modules together, but also for connecting the side wall modules and the ceiling wall modules together, the vertical reinforcing rods to which the vertical or horizontal connecting members are connected. Horizontal reinforcement rods are also provided.

In a preferred embodiment, there is provided in particular a welded wall module in which the reinforcing rods extending horizontally in the assembled state are tightly coupled with a support member having at least one anchor plate at the end side, in which case each anchor is provided. The plate is surrounded by a U-shaped saddle element with one base plate and two leg plates, in which case the leg plate is firmly engaged with the associated horizontal connecting member on its side, In particular, it is welded. The saddle member is preferably implemented in one piece.

In the above embodiment, in the assembled state, the bottom face of the saddle member is preferably in contact with the front face of the anchor plate, and the saddle member is dimensionally designed such that the flexible seat described above in particular with respect to the spacing of the leg plates is realized. In other words, the flexibility required for the connection in this variant is preferably realized by the possibility that the saddle member can move relative to the anchor plate.

In one preferred variant, each support member consists of only one square anchor plate, in particular welded, in tight coupling with a total of two reinforcing rods.

In an alternative variant, each support member comprises two square anchor plates which are mutually coupled via two square transverse plates, in which case the support member is tightly coupled with four associated reinforcing rods, in particular welded And in this case each of the two anchor plates is surrounded by a saddle member connected to the horizontal connecting member. More specifically, in this variant, the connecting unit in the wall module comprises a total of four parallelly extending reinforcing rods, which are provided with connecting units each having two connecting members on the end side. .

In the above modification, the support member in the form of a frame may be embodied integrally in a preferred shape.

In a particularly preferred embodiment, each horizontal connecting member is a stud bolt provided with a bush provided with an inner helix in a feminine implementation and an external helix provided in a complementary masculine implementation and with an associated counter nut. (stud bolt), in which case the masculine connecting member and the feminine connecting member are preferably in interaction with each other according to the type of tightener.

In this embodiment each bush is screwed onto a stud bolt provided for the purpose of securing to the saddle member at an end facing towards the support member.

It is also preferred that the leg plates of the individual saddle members are aligned parallel to the reinforcing rods extending horizontally and have receiving slots limited by slot edges extending parallel to the reinforcing rods, in which case the relevant connections Individual stud bolts of the member are pressed along the receiving slots between the leg plates and tightly engage the leg plates in the region of the slot edges, in particular welded.

The variants described so far are particularly suitable for horizontal reinforcing rods and horizontal couplings. Especially suitable variants for the vertical joint will be described below.

In a preferred embodiment, there is provided a wall module, in particular a welded wall module, in which the reinforcing rod extending vertically in the assembled state is tightly coupled with the support member at the end side, in which case the support member is adapted to penetrate the stud bolts provided with outer helix. With a set, the stud bolt acts as a vertical connection member upon interaction with two anchor nuts threaded and optionally anchor plates which are penetrated by the stud bolt.

The flexibility of the vertical joints specified in this embodiment is preferably achieved by the stud bolt having a slightly smaller diameter than the sheet surrounding the stud bolt, in which case the sheet is in particular by an associated recess in the support member or It is realized by the corresponding recess in the anchor plate.

In this embodiment, it is preferred that each support member comprises four square frame plates interconnected according to the type of rectangular frame, in which case the two frame plates facing each other are envisioned as anchor plates, one reinforcing rod And each are tightly bonded, especially welded. More specifically, the vertical connection unit in the wall module preferably has two reinforcing rods.

For all of the variants described so far, one embodiment of a wall module with an outer shell, an inner shell and a core filling in between, according to the sandwich construction, is preferred, in which case the outer shell and the inner shell Are mutually secured to the longitudinal displacement via reinforcing members which may further comprise additional units in addition to the reinforcing rods of the connecting unit.

A structure consisting of a plurality of wall modules of the above-described type, interconnected via flexible connecting members, meets the requirements mentioned in the preamble in an excellent manner.

Preferably, the seams present in the construction of the building between the wall modules, and in some cases the recesses present in the individual wall bodies in the area of the connecting member, are cast out of concrete.

The systems presented and described so far with prefabricated module / wall profiles in the element wall structure have a very high flexibility while resulting in standardization and optimization of the overall configuration, design and construction sequence.

The system can be applied to any building that has to withstand the external and internal events described above due to its function within the plant. This means that not only can the system be applied to nuclear power plants, but the system can also be used in the chemical, military and other fields.

The element coupling is designed such that the defined reinforcement values can be delivered in the form of a complete joint (100% power transmission). In this design, each reinforcing rod was connected to the reinforcement of the subsequent part, whether or not the stressability was achieved.

Although various forms of connection for wall elements have already been described in the description so far as wall modules and which meet the requirements raised in an excellent manner, additional forms have been provided to provide a flexible and detailed solution for various requirements. There is a need for them and for existing forms of variation. In such a need, in particular, an economical connector or connecting system is useful, which is simply considered in configuration and from material requirements, in which case the connector or connecting system can be simply and reliably connected to the reinforcement of the wall element, and mutually Can be connected.

For this purpose, a connecting system for a prefabricated building element structure with a plurality of wall modules can be provided, in which case the connecting system comprises one or a plurality of parts in the following groups:

The prefabricated building element system according to the present invention, in one preferred variant, has an optional accessory shell having a wall thickness of only 0.40 m and a thickness of about 0.10 m. Thereby, all the loads and load combinations described above are reliably absorbed.

The advantages achieved by the invention are, in particular, that a "construction kit system" with prefabricated and standardized wall modules or wall profiles is provided, in which case the wall modules or wall profiles are provided with expensive flexible connections or Couplings are provided, and the couplings or couplings apply several advantages that have long been known from conventional prefabricated building element structures with respect to design and implementation time, cost and efficiency to building construction for nuclear power plants. Naturally, however, the invention is not limited to this purpose of use, but rather can be used, for example, for non-nuclear industrial installations, military installations or even for conventional buildings in areas subject to strong earthquake threats.

The same reference numerals have been given to parts which have the same or identical functions in all figures.

The wall module 2 according to the invention is embodied as a concrete prefabricated building element with a connecting unit 4 partially cast in concrete, in this case with complementary connecting members 6 of corresponding neighboring modules. The connecting member 6 for engagement is projected or raised out of the individual wall body 8.

The horizontal connection unit 4 of the first type is shown in perspective in FIG. 6. The connecting unit 4 comprises two reinforcing rods 10 extending in parallel and equal in length, which are welded to the front of the square anchor plate 12 at each end. Each anchor plate 12 is surrounded by a U-shaped saddle member 14, which has one base plate 16 and two leg plates 18. Each saddle member 14 is preferably embodied in one piece (although one variant is shown in the figure consisting of a number of individual components), and the leg plate 18 is to some extent the reinforcing rod 10. Is arranged to form an extension of the reinforcement, in which case the reinforcement rod again extends outward in the shape of a connecting member 6 aligned parallel to the reinforcement rod 10. Each connecting member 6 comprises a stud bolt 20 provided with an outer helix, in which case the stud bolt is coupled between the receiving slots 22 of the two associated leg plates 18 at their inner ends. And the slot plate 24 is welded to the leg plate 18. The outer end of the individual stud bolt 20 is provided with a bush 26 with an inner helix in a feminine implementation or a counter nut 28 in a masculine implementation, resulting in a neighboring wall module. Between the complementary connecting members 6 of (2), a coupling part of a corresponding forced coupling method can be produced depending on the type of tightening-engagement part.

By means of the corresponding dimensional design of the parts, in particular the dimensional design of the length and width of the base plate 16 of the individual saddle member 14 proportional to the length and width of the anchor plate 12 surrounded by the saddle member 14. Thereby, the predetermined transverse possibility of the saddle member 14 relative to the reinforcing rod 10 rigidly cast inside the wall body 8 of the wall module 2 and in addition the predetermined connection of the associated connecting member 6. The possibility of transverse movement of is assured, in particular by at least 2 mm, preferably at least 5 mm in any one direction perpendicular to the longitudinal direction of the reinforcing rod 10. A corresponding recess is provided in the generally square wall body 8 in the region of the individual saddle member 14, so that such a possibility of movement actually exists. In this way, building element tolerances which inevitably appear in the manufacture or fastening of the joint can be compensated as necessary.

The second type of horizontal connecting unit 4 shown in FIG. 7 is configured very similarly in terms of its functional manner, but has a double number of connecting members 6 and a reinforcing rod 10. Thus, on each side there are provided two anchor plates 12 arranged in parallel with each other and surrounded by a saddle member 14 with an associated connection member 6, in which case the anchor plates 12 are It is connected to each other through the horizontal plate (30). The frame formed from the anchor plate 12 and the transverse plate 30 may be integrally implemented. The reinforcing rod 10 is welded to the front of the anchor plate 12 or alternatively to the transverse plate 30. In this way, on each side of the connecting unit 4 a double-tightening-coupling portion with the above-described flexibility can be implemented to some extent.

8 shows a vertical connection unit 4 which basically has a similar principle of function but has a different connection member 6 structure in detail. In other words, in this figure, two reinforcing rods 10 are welded with a rectangular frame formed from four frame plates 32 at the end side. Inside the rectangular frame facing towards the reinforcing rod 10, an anchor plate 36 provided with a central recess 34 is welded to the frame plate 32. The diameter of the central recess 34 is designed such that the stud bolts 38, also referred to as fixing bolts, can be inserted through a predetermined interval, that is to say, forming an annular gap. Anchor nuts 40 are used to reinforce and secure the joints produced by the counter parts of the neighboring wall modules 2, where the joints are likewise anchored by corresponding stud bolts 38. It is fixed through the plate 36. In this case, the difference according to the masculine connection type and the feminine connection type is not necessary, but may be naturally provided as an alternative embodiment. Alternatively in this case as well, a clamping bush or similar member may be used again to interconnect the opposite ends of the stud bolts 38 of the neighboring wall module 2.

It is again important that the vertical coupling and the horizontal coupling allow some flexibility corresponding to an adjustment gap of at least 2 mm, preferably at least 5 mm, perpendicular to the longitudinal direction of the reinforcing rod 10.

In all cases the longitudinal displacement loads, tensile loads and shear loads are reliably removed and transmitted continuously through the reinforcing rods 10 cast inside the concrete of the wall body 8 according to the type of the regular rectangular grid as a whole.

In the drawings all component parts and elements joined from each other welded together (weld seams 42) may also be implemented in one piece in alternative embodiments, namely cast or cold deforming or It is produced by hot deforming.

The connector types described below can replace the connectors shown and described in FIGS. 1 to 11, referred to as " connecting members " in FIGS. 1 to 11, and can partially or completely replace the connector or The connectors may be combined or interact in various ways.

In the description of FIGS. 12 to 30, a number of embodiments of the connecting system according to the invention for a wall module of reinforced concrete prefabricated construction are described in detail with reference to the drawings.

Facts that apply to all examples below: Buildings are prefabricated modules from reinforced concrete in the form of wall members, ceiling members, corner members and similar members (hereinafter simply referred to as "wall modules") or It is embodied as a large structure consisting of prefabricated building elements, in which case the term "wall member" is used as synonym. The joining between the prefabricated members is achieved using a special connector or connecting system based on the screw connection. The prefabricated wall modules can be almost arbitrarily combined with each other.

Threaded connections meet the requirements for periodic alternating stresses occurring during seismic events or equivalent natural events and in the case of unusual loads such as, for example, explosion or impact loads.

One wall section consisting of three rectangular wall modules 2 of the same type is shown in perspective in FIG. 12 as an example.

1. U shape carrier  Type screw connection

Between the prefabricated building members, in particular implemented as reinforced concrete members, a U-shaped carrier is arranged that is continuous, that is to say preferably extends over the entire edge length of one or more members, in which case the U-shaped carrier has a reinforcement grid. Incisions / holes are provided correspondingly to the reinforcement spacing. In order to compensate for the tolerance, the prefabricated building member may be provided with an excess portion relative to the threaded insertion of the reinforcing rod.

As the thickness of the U-shaped carrier, at least 20 mm, preferably 25 mm may be recommended. The connection to the concrete member is made by a nut, which is screwed onto the protruding reinforcing rod or reinforcing bar provided with the corresponding helix on the end side.

Support disks or screws / with finished collars to ensure sufficient support area, because the holes in the U-shaped carriers must have a significant excess of the screw connections to compensate for tolerances. Nuts are preferred.

The U-shaped carrier is inserted under the connector and screwed in.

Such a connection type is shown by way of example in FIGS. 13 and 14.

FIG. 13 shows a cross section of a vertically aligned wall module 2 with an associated accessory shell 1003. At the top and bottom edges of the wall module 2, a U-shaped carrier 1004 is visible, through which the coupling to adjacent wall modules not shown in the figure is carried out. Each of the U-shaped carriers 1004 abuts the edge face of the associated wall module by its own legs 1006 and forms a predetermined spacer between neighboring wall modules. For a secure engagement between the U-shaped carrier 1004 and the wall module 2, an end (screw connection) of the reinforcing rod 10 protruding from the wall module and provided with an outer helix is formed in the leg of the U-shaped carrier. Passing through the long hole, each is fixed by a counter nut 1010 screwed from the outside.

Since the bores / long holes formed in the leg 1006 of the U-shaped carrier 1004, through which the ends of the reinforcing rod 10 pass, are often dimensionally designed from the diameter, as a result the counter nut 1010 is dismantled. The reinforcing rod 10 preferably has a gap corresponding to at least 5 mm in each direction.

The reinforcing rods 10 preferably pass through the entire wall module 2 from edge to edge or from connection point to connection point, respectively. In other words, each reinforcing rod 10 has one connector of the type described above at its two ends, the connector interacting with an associated connector of an adjacent wall module. The two connectors at opposite ends of one reinforcing rod 10 are preferably of the same type and dimensioned in the same form. This also applies to the additional connection types described further below.

Fig. 14 shows in plan view the joint manufactured as above between two wall modules. In this schematic view only horizontal reinforcing rods 10 can be seen among the wall modules themselves.

In the case of a correspondingly implemented reinforcing grid, in this way not only vertical couplings but also horizontal couplings can be produced between adjacent wall modules.

2. Screw box type

The box type screw couplings described below are also suitable for the vertical coupling as well as for the horizontal coupling.

This connection type is described in detail with reference to FIGS. 15 to 18.

FIG. 15 shows a perspective view of the reinforcement grid 1012 of the rectangular wall module 2 with boxes 1014 connected to the reinforcement rod 10 at the end side, respectively, in the left half of the figure. The right half of the figure shows the transport module wall module 2 coated with a concrete casting compound. When coupling the wall module 2 with the relevant box 1014 of the neighboring wall module 2, each box 1014 is joined by a screwing method.

FIG. 16 shows a longitudinal cross-sectional view of the box-box combination which is mutually coupled in the same way as above at the connection site of the two wall modules 2.

FIG. 17 and FIG. 18 show two cross-sections marked with Roman numerals corresponding to FIG. 16.

On the side facing the wall module 2, each box 1014 is connected and fixed to the end of one reinforcing rod 10. This connection and fastening is made via or in a similar manner as the so-called LENTON-screw sleeve coupling 1016. For this purpose, the ends of the reinforcing rods 10, which are gradually narrowed into a conical shape and provided with an outer helix, are screwed inside a complementary formed spiral bush 1018 or threaded sleeve, in which case the spiral bush or The screw sleeve forms one integrated component of the box 1014.

The mutual coupling of the two boxes 1014 of the same shape is made by connecting bolts 1020 placed inside, and both ends of the connecting bolts are provided with outer spirals, respectively, and the connecting bolts are connected with the associated bolt channel ( 1022). Screwed counter nuts 1024 each contact the annular bush 1028 of the associated box 1014 that defines the bolt channel 1022 through an anchor plate 1026 that is in the middle to secure the device. The ring front 1030 of the individual annular bush 1028 then forms a support surface for the anchor plate 1026 that acts as a stopper and is formed along the shape of the backing disk provided with the slot. Thereby, the annular bushes 1028 of the two boxes 1014 and, together with the two boxes 1014 as a whole, are tightly pressed together.

On the one hand the inner diameter of the bolt channel 1022 is larger than the outer diameter of the connecting bolt 1020 and on the other hand each anchor plate 1026 is formed by an enclosure formed by the wall of the box 1014. very good because there is enough movement space inside the enclosing, and finally there is a sufficiently large axial clearance between the individual counter nut 1024 and the spiral bush / screw sleeve 1018 opposite the counter nut. A joint is made that can be adapted. At this time, the size of the movement space present in all three spatial directions with the counter nut 1024 not yet tightened reaches preferably at least 5 mm.

3. Screw Terminator Type

One further connection type is likewise suitable for the vertical coupling as well as for the horizontal coupling as shown in FIGS. 19 to 25.

Individual connectors are shown in perspective in FIG. 21 and in plan view in FIG. 23-25 show various cross sections of the individual elements of the connector.

In this type of engagement, the individual reinforcing rods 10 of the wall module 2 are fixed inside the closing plate 1034, also referred to as terminator, at the end side. Such fastening can be effected in particular by screwing, for example using a Lenton-screw sleeve joint or similar member, in which case the helical bush 1036 or screw sleeve is provided by a closing plate 1034. It is inserted and fixed in a shape-fitting manner in the corresponding bore (see FIG. 24).

The engagement of the two closure plates 1034 is again via threaded bolts 1038, which are screwed through the associated bores by the closure plates 1034 and secured by nuts 1040. The steel plate 1042 correspondingly penetrated between the nut 1040 and the closing plate 1034 acts to some extent as a support disk.

In this embodiment two threaded bolts 1038 are provided which are arranged symmetrically and parallel to the central axis of the reinforcing rod 10.

Also important in this embodiment is the excellent adaptability of the joint to adapt to manufacturing tolerances or measurement inaccuracies and alignment inaccuracies which are again unavoidable upon assembly. For this reason, if the inner diameter of the bore in the closing plate 1034 penetrated by the screw bolt 1038 is larger than the outer diameter of the individual screw bolt 1038, as a result the nut 1040 is dismantled or detached In all directions a desired degree of freedom of movement (in other words a gap) of at least 5 mm is realized. This fact is revealed for example from FIGS. 24 and 25.

The length of the screw bolt 1038 may preferably be dimensioned such that a significant gap is left between the two closing plates 1034 which are mutually engaged in the assembly final state. Such gaps are preferably cast into a filling material such as, for example, fine particles of concrete or mortar when completing a building consisting of the wall module 2. This fact applies similarly to the gaps, seams and intermediate spaces at the junctions of neighboring wall modules in the other connection types described in this application.

The spacing of neighboring parallel reinforcement rods 10 of the reinforcement grid 1012, as seen in FIG. 20, typically lies within a size of 200 mm. The value is also based on the other linkage variants described in the present application, for example, in which case considerable variations are possible depending on the application. Typical values for the diameter of the threaded bolt 1038 are in the range of 20 mm or more.

4. Claw  Ⅰ type screw connection

This joining part has some similarities to the screwing of the U-shaped carrier. Screwing of the reinforcing rod is not carried out by the sleeve, but rather a metal claw which guarantees a complete joint is screwed to the end of the reinforcing rod. In addition, a metal plate that completes the carrier profile for the closed rectangular ring is screwed onto the U-shaped carrier. The seams between the wall modules are preferably cast again.

Such a situation is shown in perspective view in FIG. 26 and in cross-sectional view in FIG. 27.

In FIG. 27, a metal claw 1046 is shown coupled to the individual reinforcing rods 10. The metal claw is integrally implemented and has a spiral bush 1048 screwed onto the reinforcing rod 10 and a fixing leg 1050 protruding from the side and disposed at right angles to the spiral bush. The end of the reinforcing rod 10 with the helical bush 1048 passes through a bore formed with a significant gap inside the leg 1052 of the U-shaped carrier 1054, resulting in a fixed leg of the metal claw 1046 ( 1050 is fixed inside the U-shaped carrier 1054. Metal plate 1058 screwed onto the U-shaped carrier 1054 closes the U-shaped profile into one box.

Similar to the combination of the U-shaped carrier type, the box disposed between the two mutually coupled wall modules 2 preferably extends over the entire edge length of the wall module.

5. Claw  Type II screw connection

This type of connection is provided with a metal claw 1060 screwed to the end side of the reinforcing rod 10, similar to the claw I type of engagement. However, unlike the claw I type of engagement, the U-shaped clamp 1062 does not extend over many or all connections of one side edge of the individual wall module 2, but rather only over the connector itself. The fixation is made by screws 1064 extending perpendicular to the longitudinal axis of the reinforcing rod 10, which is shown in perspective view in FIG. 28 and in cross-sectional view in FIG. 29.

6. Coupling by double head anchor

Finally, alternatively or additionally to the type of connection described so far, so-called double head anchors can be used as connection means, which connection means are inserted into corresponding recesses inside the wall module. This ensures the possibility of transferring tension to the corresponding wall joint.

The connection system is illustrated by reference to one cross section of the two wall modules 2 mutually coupled in FIG. 30. In this example, two dual head anchors 1070 disposed at right angles to each other are combined into one anchor cross 1072. In particular, the two double head anchors 1070 may be firmly coupled to each other at the intersection of the anchor cross 1072. The anchor cross 1072 may also be integrally cast. Alternatively, a simple double head anchor 1070 can of course also be used.

Each dual head anchor 1070 has two thick heads 1074 which project radially, which heads are integrally formed with one anchor bar 1076 at the end side, respectively. It is fixed in a shape-fitting manner in the corresponding recess or groove of the associated wall module 2. After assembly, the recess is preferably cast from a filling material such as, for example, mortar or lightweight concrete.
