Prior to the development of the new synthetic plastic wall ties described herein, metal wall ties having cones at both ends were known. This type of tie is placed in a form and then concrete is poured. After the concrete has hardened, the worker then taps the end of the wall tie with a hammer to break the wall tie. This type of metal wall tie is referred to as a "snap tie" and can be broken by tapping the cone and then removed from the formed concrete wall. The hole is filled to obtain a flat finished surface.The novel tie described herein consists of different structures and functions of different means providing a disc-shaped member integrally formed with the tie.Ideal These synthetic plastic discs or stops are formed from large diameters. Concrete wall manufacturers also use wall ties that have a metal washer-like member that slides onto the end of the wall tie. The wall tie has spaced apart seals so that when the metal washer member is moved and positioned on the wall tie, the metal washer member reaches the seal at the inner edge of the washer. The new and improved wall ties described herein are integrally, fixedly, and positively secured to the tie and act to hold it in position relative to the seal on the tie. In addition, traditionally used metal ties and metal washers are provided below the structure because, at least in some types of wall construction, potential This is because water leakage problems occur and these metal components tend to break and corrode.

Another feature of the invention is that the new and improved synthetic plastic concrete wall tie has a pair of circular flanged water seals extending radially outwardly of the intermediate wall tie section; The seal acts to inhibit water flowing axially or along the length of the wall tie and through the concrete wall structure in which the tie is embedded; It serves to provide a means for installing reinforcing rods extending perpendicularly to the wall tie when securing the tie to the concrete formwork.

Other features of the invention include slotted formwork sections having slots extending in a number of rows along the upper and lower edges of the formwork sections and unique end formations to facilitate the installation of wall ties. It is an object of the present invention to provide a new and improved synthetic plastic wall tie having the following properties.

Next, the present invention will be explained based on the attached parts.

In FIG. 1, 10 generally indicates a unitary foamed plastic concrete formwork structure. The structure shown in FIG.
Name: "Permanently non-movable insulated type concrete wall forming structure".

The structure 10 includes a pair of unit structure forming panels 11 and 1.
2, these panels 11 and 12 are spaced apart from each other and, when properly installed, act as a formwork into which concrete can be poured. Each panel consists of a series of unitary concrete-formed sections 13 that are identical to each other except for certain areas, as will be explained below. These sections are easily cut and placed to form window openings 14. Panels 11 and 12
cooperate with end closure panels 15 extending between forming panels 11 and 12 and between forming sections 13 to confine poured concrete. The window opening 14 can also be provided with a closing panel 16.

Panels 11 and 12, section 13, closure panel or end piece 15, window panel 16 and curved corner panel 17 are all comprised of expanded plastic, preferably expanded polystyrene. This material has unique insulating properties and strength that allow concrete walls to achieve good insulation which prevents the conduction of heat through foam walls, and these and other properties will be discussed below.

In order to appropriately reinforce the concrete formwork structure 10,
In the present invention, a new and improved wall tie 18 has been developed which is preferably comprised of polypropylene containing 20% calcium carbonate.

This thermal wall system
tem) is a completely new concept in energy efficiency building technology. Expanded polystyrene building block sections act as permanent formwork against the concrete. This system of construction is utilized for energy savings and speed of assembly.

Expanded polystyrene (EPS) is a closed-cell, rigid, lightweight cellular plastic (white) that can be molded into various shapes using steam and pressure. Thermal wall system panels can be made from modified polystyrene.

The density of the panel is. It is in the range of 7 to 2.0. Typical physical properties of EPS insulation are shown in Table 1 below. Like all organic materials, EPS is flammable and must not be exposed to flame or other ignition sources.

The basic architectural components of the thermal wall system of the present invention are two solid (2 inch) panels 11 and 12 of polystyrene connected with high impact plastic ties 18. The length of tie 18 determines the width of the concrete wall. Each block or section 13 has its upper edge or surface 2

20 and coincide with the parapet attachment along its lower edge 23 (Fig. 1). Blocks or sections 13 are placed on top of other blocks and pressed using a simple hand press. The parapet attachments are combined and aligned together to create a perfectly flat surface. block or section 1
The vertical end of 3 has well interlocking projections 24 and grooves 25 (FIG. 10). The blocks or sections 13 stand upright on top of the leg members or directly on the floor 5lab.

The leg members must be horizontal and flat. When placing concrete, the first set (firstlift
) Check the horizontal and vertical levels with special attention.

Each end closure panel 15 has alternating vertically extending hooked ribs and grooves, generally indicated at 26, with hooked ribs 27.
and hooked grooves 28 (FIG. 9) are formed to complement each other and allow the ends of the end closure panel 15 to slide over the interlocking assembly of the sections 13-13. The sections have ribs 27 and grooves 28 that are integrally formed with the associated section 13, and when assembled the ribs 27 and grooves 28 on the side panels 11 and 12 abut each other.

Ties 18 cooperate with upper and lower rows of T-shaped slots 29 formed in each section 13. The slot 29 is open inwardly so that when the two sections 13-13 are placed in opposing relationship as shown in FIG.
The T-shaped slots face each other. Tie 18 is provided with a T-shaped tie end 30-30 having a profile that matches the shape of slot 29 and that can be slid together when the sections are assembled. Can be multiplied. Tie 18 provides a robust concrete formwork structure when engaged with both sections along the upper and lower edges of tie 18'.

Compare Figures 4 and 5, which show two different types of ties 18 and 18'. Thailand 1
Ties 18 and 18' are the same except that 8' is a short tie and can be used to form concrete walls as narrow as 8 inches. Long ties 18 can be used to form 10 inch thick concrete walls. The length of the tie can be varied as required. Tie 18 has the same structure as tie 18', but the differences will be described later.

For ties 18', each tie 18' has an intermediate or center-
A pair of triangular truss sections 32 are provided at opposite ends of the intermediate section 31' in an integral one-piece structural assembly. Intermediate web section 31 joins the truss section at the triangular top of the triangular truss section. Triangular truss sections 32 and 33 thus define triangular truss openings 34 and 35. These openings are
Allowing the concrete to flow freely through the ties without obstruction and thus not acting as a dam, but rather restricting the flow of liquid concrete into the mold or formwork when pouring the concrete.

The triangular truss sections 32 and 33 terminate in truss ends 36 and 37 and further include T-tie ends 30-30.
merge into. Each truss end includes a cross piece portion 30a and a stem portion 30b. Further, the truss section defines truss legs 3g, 39.40 and 41;
The truss legs preferably have a diameter of about 3716 inches.

The tie 18 is also provided with upright fingers 42-42, and one
Pairs of fingers are provided at each end of the tie and specifically join adjacent truss legs. The fingers 42 cooperate with the truss legs to form a V-shaped cutout 43 for receiving the reinforcing rod 44. The tie is configured to form a finger 42 defining a notch 43 and can be positioned to secure a concrete rod 44 at that point when liquid concrete is poured into the formwork, and for this purpose the concrete -) The reinforcing rod does not spring up and move when injecting C onto it.

Short tie 18' differs from tie 18 by having a single pair of upright fingers 45, as shown in FIG. 5, which extend above and below the tie midsection. . The fingers 45 and the intermediate section 47 together define a notch on each side of the finger so that the rod 44 can be positively secured to the tie when the concrete rod 44 engages the notch, and the rod will no longer move laterally during concrete pouring.

In another important feature of the invention, an embossed I-5hap display as shown in FIG.

Embossed I-shaped indicia 50 are on both sides of the section and T-
The spacing between the embossed I-shapes can be varied as required. This spacing of indicia may be on the order of every 6 inches along the length of the section.

The embossed I-shaped indicator 50 can be used as an "indicator" or as a blind slot locator to attach screws to the tie 18, specifically through the T-shaped end 30 of the tie and to the T-shaped end of the tie.
The screws 52 act to attach the splint 51 by screwing directly into the stem portion 30b of the shaped end 30 to securely anchor the splint 51 to the section 13.
~Figure 9). Thereafter, the wall sheathing 53 can be suitably attached to the splint 51 by means of additional threaded fasteners, as shown at 54 in FIG.

Ties 18 and 18', shown as long ties 18 and short ties 18', are preferably constructed with the following approximate dimensions: Tie Length Tie ζ D Height Flat Thickness Stem Width Figures 11-16 show a modified wall tie structure 19'. A tie of this shape according to the present invention, as shown by way of example, omits the truss portion of the tie shown at 18 in FIGS. 2, 3 and 4. This tie 19' (FIG. 13) has been found to be superior to ties with trusses. This is because, in the case of ties with trusses, there is no possibility of interfering with the lateral flow of concrete in the formwork, as is often encountered with ties of the type that use the truss concept as shown in FIG.

In order to appropriately reinforce the concrete formwork structure 10,
In accordance with the present invention, a new and improved wall tie 19' has been developed which is preferably comprised of polypropylene containing 20% calcium carbonate. This improved wall tie 19' can be used in the same manner as the wall tie 18 shown in FIG. As a preferred structure, in the present invention, the tie is formed into a single structural unit (o
It is made as a new piece unit). However, it is undesirable for ties to be made up of multiple components.

Figures 4 and 5 show two different types of ties, which are the same as ties 18 and 18'. Ties 18 and 18' are nearly identical except that tie 18' is a short tie and can be used to form narrow concrete walls, such as 8 inches thick.

Long ties 18 are adapted for use in forming 10 inch thick concrete walls. □The length of the tie can be changed as necessary.

Tie 19' is similar in structure to tie 18', but
The differences will be discussed later. Tie 19' shown in Figure 13
can be easily changed and used.

Intermediate wall tie section 31' has ends 36' and 37
' and further merges into T-tie ends 30'-30'. Each tie end includes a cross piece portion 30a and a stem portion 30b.

Tie 19' includes a pair of circular flanged water seals 42 extending radially outwardly from intermediate wall tie section 31'.
'-42' is provided. The seal 42' includes a wall tie section 30' that receives reinforcing rods 44' on the sides of the seal.
jointly with If desired, rod 44' can be wired to a tie. The diameter of the rod can be varied as per the builder's requirements. Generally, the diameter is 172 ~
It can be made in the range of 778 inches. The water sealing part 42' is the first water sealing part 42'.
It is preferably located 2-1/2 inches from the inner end adjacent stem portion 30b to outer surface 46' on water seal 42' as shown at 45 in FIG. The portion of the water seal can be varied so that the main seal can be brought closer to the mold gate 47' if desired (FIG. 4).

Generally, the water seal 42' is connected to the end surface 45 of the stem portion 30b.
It is impractical to approach the reinforcing rod 44' for this reason, so that a sufficient spacing can be provided for the reinforcing rod 44'.

Generally, the reinforcing rod 44' is connected to the conc +J + to be injected.
It is preferable not to place it closer than 2 inches from the outside surface of the wall. By providing a 2-inch gap between the exterior surface of the concrete wall to be poured and the exterior surface of the reinforcement rod 44', the reinforcement rod can be moved far enough away from the exterior surface to move the rod closer to the exterior surface of the concrete wall to be poured. Problems that may occur when locating the

In the preferred construction of the present invention, tie 19' is twelve inches long, and this length can be varied as desired. If the tie is configured to provide a water seal 42' that defines the notch 43', the concrete rod 44' can be fixedly positioned at that point when liquid concrete is poured into the formwork, and this Therefore, the reinforcing rods may spring up when pouring concrete C,
You can prevent it from moving.

The water seal 42' can form a notch 43' in which case the wall tie is placed with the top side of the wall tie in either position by either side thereof.

Preferably, the wall tie 19' has a water seal 42' formed at least 1 inch in diameter and has a thickness of approximately 100 inches. Excellent results can be achieved by constructing the wall tie with a water seal of the construction and dimensions described above.

Another important feature of the invention is the provision of an embossed square-shaped indicia 50 as shown in FIG.

Embossed I-shaped indicia 50 are arranged in a number of rows on the outer surface adjacent the upper and lower edges of each section 13 in a transverse array with T-shaped slots 39 opening into opposing surfaces or faces of the sections 13. Separate upright. Embossed I-shaped display 50
has a stem portion 29a of the notch 29 and an upright portion 58 arranged laterally (FIG. 5).

Embossed I-shaped indicia 50 are provided on each side of the section, opposite each row of T-shaped slots, and the spacing of the embossed I-shaped indicia can be varied as desired. This spacing of indications can be as much as every 6 inches along the length of the section.

An embossed I-shaped indicator 50 (FIG. 14) acts as an "indicator" or "blind slot locator" to allow the splint 51 to be attached by screws 52 (see Fig. 14).
and Figure 7). In this case, insert the screw directly into the tie 19',
The splint 51 can be securely anchored to the section 13, preferably by screwing through the T-shaped end 30 of the tie. Thereafter, wall covering 53 may be suitably attached to splint 51 with additional threaded fasteners as shown at 52 in FIG.

Tie 19' cannot be tested similarly to tie 18 as described above, but a comparison can be made based on knowledge and experience from manufacturing this type of tie when tie 19' is made from the same material. Test results can be obtained.

The thermal wall structure of the present invention presents a new construction article made from expanded polystyrene that acts as a permanent formwork for concrete structures. The main advantages of this product are its quick assembly and extremely high thermal insulation properties.

Similar products are widely available in Switzerland, Belgium, France, Germany, Venezuela, Australia and the United States. This has been used for nearly 20 years. A simple building system, trade name rARc.

The aerial block, made from Dylite J expanded polystyrene and flame retardant additives, is assembled in a Lego J style with its toothed tops and grooved bottom. Plastic ties hold the sides together. The length of the tie is defined by the width of the cavity or wall, and the blocks are connected horizontally and vertically. Once assembled, the concrete is insulated into the load bearing structure.
d bearing 5structure) into the wall cavity forming the bearing.

Aspiration Building Block or Section 13 in the Invention
consists of EPS (expanded polystyrene) panels 2 inches thick, 12 inches high and 40 or 20 inches long. The density is nearly twice that of ordinary insulation boards. All external finishes may be applied. Resilient coating scores and stucco finishes can be used as siding or facings. The interior is finished with dry wall, plaster, tile or any other conventional means.

The thermal wall structure of the present invention is an advantageous structural system where energy retention (by reducing heat transfer) and speed of construction are important. Ensures inherent low thermal fluctuations without risk of cracking of any external priming and internal plaster work. The maximum possible expansion is 0.2+nm/m.

Also, superior noise and impact sound reduction is an important advantage of thermal wall systems. I think a 10dB difference is roughly half the amount of noise. 35QKa/mz thermal wall 250 addition is 49dB.

Expandable polystyrene does not rot and, when properly used in building construction, does not undergo any other type of deterioration during use.

Dairich Expandable Polystyrene panels are 2 inches thick, 12 inches tall and 40 or 20 inches long.
Inches. Horizontally spaced rows of "t" or T-shaped slots 29 are located along the top and bottom of each section. T-shaped ends 30-30 of tie 18 are inserted into slot 29. These ties 18 hold section 13 and panels 11 and 12 together and also define the width of the wall. Each block or section 13 has a parapet attachment along its top surface and aligns a parapet attachment 20 along its underside as described above. Block 13 is placed on top of the other blocks and joined together using a simple press, meshing the parapet attachments together to create a perfectly smooth surface and solid 5 structure.
). The blocks are assembled directly onto the top of the leg members or onto the floorboard as described above. The legs should be as level and flat as possible. When pouring concrete, special care must be taken to check horizontal and vertical levels in the first three feet of pouring. This is important to further enhance small errors and changes at early levels. The lightness of the blocks or sections 13 and the flexibility of their average construction achieve speed and simplicity.

For corners, windows, door holes and J-junctions, special construction "end plates" can be made from expanded polystyrene and inserted into the ends of the blocks.

This end plate slides into the block and acts as a concrete bulkhead. The end plates shall be held on the inside corrugated surface of the block panel.

At the 90° corner, connect the blocks vertically, insert end plates, and use the concrete as a partition wall. Ten inch wall circular corners are advantageously used in the present invention and are specifically made from corner blocks or sections 17.

Thermal wall blocks or sections 13 can be quickly and easily cut with any conventional hand saw.

Sand the edges of the rough sanding block to establish a smooth interference fit.

The blocks or sections 13 are stacked to the desired height of 8 to 10 feet and filled with conventional cement by a concrete truck and chute or by a concrete pump. Superplasticizer additives improve the flowability of concrete mixtures without compromising the strength of the concrete. The concrete should be laid in 4 foot "lifts" or layers at a rate of 8 to 10 feet per hour.

Electrical and sanitary construction water lines and electrical conduits can be easily cut into 2-inch thick hot walls after pouring the concrete. These are then covered with dry wall or plaster. Pipes larger than 2 inches in diameter, such as drain pipes, must be placed in the wall cavity before concrete is poured.

When completely surrounded by concrete and hot wall polystyrene, the pipes are insulated and immune to freezing, even when the building is not heated.

The use of thermal wall blocks or sections 13 in construction allows for the type of energy efficient construction that is needed today (given constantly rising energy costs).

EPS (expanded polystyrene) panels 11 and 12
are joined together by plastic ties 18 to form building blocks. These blocks are connected horizontally and vertically, stacked on top of each other to the desired height and filled with concrete.

After pouring the concrete, keep the blocks in place and
A structure with an R-value of 20 is obtained.

The R-value refers to the degree of heat loss, and the R-system is a means of evaluating insulation efficiency; the higher the R-value, the greater the resistance to heat and cold.

T, W, S blocks are made from ARCO-r die-rich, flame-retardant EPS and do not burn.

It is not limited to the type of wall cladding and can be applied to internal and external materials. Generally, the exterior material has a cementitious finish and the interior material is plastered or drywalled. Panels can be glued or screwed.
