Hereinafter, an embodiment of the present invention (hereinafter referred to as the present embodiment) will be described with reference to FIGS. 1 to 8. In the following, the connection between the temporary scaffolding F and the building will be described by taking a house (specifically, a detached house or an apartment house such as an apartment or condominium) as an example of a building. However, a house is an example of a building, and the present invention can also be used for connecting another building, for example, a commercial building, a building in a factory, a store, etc., to a temporary scaffold F.

In the following description, the "vertical direction" is the direction corresponding to the height direction of the house which is a building, and the "horizontal direction" is the direction corresponding to the girder direction or the beam-to-beam direction of the house.

First, the temporary scaffold F and the wall connecting member 10 will be described with reference to FIG. The temporary scaffolding F has a scaffolding plate Ft and a support column Fb that supports the scaffolding plate Ft, and is fixed by a wall connecting member 10 at a position separated from the outer wall 20 of the building by a predetermined distance.
The wall connecting member 10 has a base end portion 11, an intermediate portion 12, and a tip end portion 13. The base end portion 11 is a cylindrical member having a screw hole formed therein, and a mounting bolt B described later is screwed into the base end portion 11. The intermediate portion 12 is composed of a long screw and a long nut screwed therein, and is configured to be expandable and contractible by rotating one of the long nut and the long screw with respect to the other. Thereby, the support column Fb can be fixed at an appropriate distance with respect to the outer wall 20 of the building. The tip portion 13 is fixed to the single pipe pipe constituting the support column Fb in a detachable state, and for example, a pipe clamp is used.

In order to attach the above-mentioned wall connecting member 10, when the temporary scaffold F is installed in the outer wall 20 of the house, the mounting bolt B ( The tip of the wall connecting member 10) is attached. The mounting bolt B is for mounting the wall connecting member 10, and is composed of stud bolts having screw portions at both ends in the present embodiment.

The outer wall 20 of the house is composed of a plurality of outer wall panels 30 adjacent to each other in the vertical direction, and a gap (horizontal joint 21) extending in the horizontal direction is formed between the outer wall panels 30.
One end (tip portion) of the mounting bolt B is fixed to the outer wall panel 30 at a position on the back side (indoor side) of the horizontal joint 21, and the other end (rear end portion) is the outer wall panel. It is fixed in a state of protruding from the panel surface of 30 to the outdoor side. Specifically, the tip portion of the mounting bolt B is connected to the wall connecting jig 40 described later on the indoor side, and the base end portion 11 of the wall connecting member 10 is connected to the rear end portion protruding to the outdoor side. Screw in. As a result, the wall connecting member 10 is attached to the outer wall panel 30, and the distance between the temporary scaffold F and the outer wall 20 is fixed, so that the temporary scaffold F can be firmly connected to the outer wall 20. It will be possible.

Next, the structure of the outer wall panel 30 will be described with reference to FIG. The outer wall panel 30 has a main body portion 31 and a frame 32 that holds the main body portion 31. The frame 32 is a steel material, strictly speaking, a frame made of lip channel steel (C-shaped steel), and is arranged at the edge of the outer wall panel 30. The frame 32 holds the main body 31 in a state where a part of the main body 31 (second heat insulating layer 31d) is sandwiched between a pair of overhanging portions 32a provided on the C-shaped steel.

The main body 31 is a portion of the outer wall panel 30 other than the frame 32, and has a breathable external heat insulating structure. The main body 31 has a face material 31a facing the outside, a ventilation layer 31b, a first heat insulating layer 31c made of high-density glass wool board, and a second heat insulating layer 31d made of high-performance glass wool. As will be described later, the ventilation layer 31b is provided with a spacer 31e interposed between the face material 31a and the first heat insulating layer 31c (see FIGS. 5 and 6).

The face material 31a is a plate material having a substantially rectangular shape when viewed from the front, and is specifically composed of a siding board. In the outer wall panel 30, the face material 31a is attached in a state where the upper end of the face material 31a is slightly lower than the upper end of the frame 32 and the lower end of the face material 31a is slightly lower than the lower end of the frame 32. Therefore, the upper end portion of the frame 32 of the lower outer wall panel 30 is located on the inner side of the horizontal joint 21 formed between the two outer wall panels 30 adjacent to each other in the vertical direction.

Of the pair of overhanging portions 32a of the frame 32, the panel fixing hardware 50 is bolted to the overhanging portion 32a located on the indoor side from the indoor side.

Subsequently, the wall connecting jig 40 will be described with reference to FIGS. 2 to 6. The wall connecting jig 40 of the present embodiment is a connecting metal fitting for connecting the mounting bolt B (the tip of the wall connecting member 10) to the outer wall panel 30. Specifically, as shown in FIGS. 2 and 3, the wall connecting jig 40 is fixed so as to overlap the upper surface of the frame 32 arranged at the edge of the outer wall panel 30, and is inserted from the outdoor side. It is connected to the attached mounting bolt B.

As shown in FIG. 4, the wall connecting jig 40 has an L-shaped cross section formed by the base portion 41 and the connecting portion 42, and is subjected to an external force applied to the connecting portion 42 via the mounting bolt B. On the other hand, it has the necessary plate thickness and width to ensure sufficient strength. That is, the wall connecting jig 40 is continuously provided on the base 41 having a joining surface to be joined to the upper surface of the frame 32 and the base 41 so as to extend parallel to the panel surface of the outer wall panel 30 for mounting. A connecting portion 42 for connecting to the bolt B (the tip of the wall connecting member 10) is provided.

An insertion hole 41a is formed in the base portion 41, and a fastening bolt hole 33 is formed in the upper surface of the frame 32. Then, by inserting the fastening bolt 43 (fastening member) into the insertion hole 41a and the fastening bolt hole 33, the base portion 41 is fixed so as to be joined to the upper surface of the frame 32 (see FIGS. 5 and 6).

Further, as shown in FIG. 4, a countersunk portion 41b capable of accommodating the head portion 43a of the fastening bolt 43 is formed on the upper surface of the base portion 41 and around the insertion hole 41a. The counterbore portion 41b has a circular bottom surface 41c and a cylindrical side surface 41d continuous with the bottom surface 41c, and forms a recess recessed downward with respect to the upper surface of the base portion 41.
As a result, when the base 41 is fixed to the frame 32, the head 43a of the fastening bolt 43 is fastened while being housed in the counterbore 41b, so that the fastening bolt 43 with respect to the upper surface of the base 41 is fastened. The amount of protrusion of the head 43a is suppressed (see FIGS. 3 and 6).
In the present embodiment, when the base 41 is completely fastened to the frame 32, the head 43a is in a slightly protruding state with respect to the upper surface of the base 41, but the depth of the counterbore processing is changed. This may prevent the head 43a from protruding from the upper surface of the base 41.

Further, in the present embodiment, the diameter of the bottom surface 41c having a circular shape is 1. It has more than twice the size. As a result, when the fastening bolt 43 is tightened, interference between the tightening tool of the fastening bolt 43 and the side surface 41d of the counterbore portion 41b is avoided. Therefore, the fastening bolt 43 is housed in the counterbore portion 41b. It can be easily tightened.

The connecting portion 42 is formed with a connecting hole 42a into which a mounting bolt B (mounting member) is inserted. The connecting hole 42a may be screwed inside. Further, a nut that is screwed with the mounting bolt B in accordance with the connecting hole 42a can also be used.
As shown in FIG. 3, the first heat insulating layer 31c is sandwiched between the connecting portion 42 and the overhanging portion 32a located on the outdoor side of the frame 32. When the mounting bolt B is directly fastened to the frame 32, it is necessary to make an insertion hole for the bolt to pass through the first heat insulating layer 31c, but if the wall connecting jig 40 is used, the first heat insulating layer is used. The wall connecting member 10 can be fixed without making a through hole in 31c.

As shown in FIG. 4, a pair of notches 42b and 42b and a tongue piece 42c are formed at a position sandwiched between the pair of notches 42b and 42b at the lower end of the connecting portion 42 which is a free end. As shown in FIG. 6, the notch 42b is formed in a position and shape that avoids interference between the connecting portion 42 and the spacer 31e when the wall connecting jig 40 is fixed to the frame 32. Here, as shown in FIGS. 5 and 6, the spacer 31e is interposed between the face material 31a and the first heat insulating layer 31c, and is arranged in the vicinity of the attachment position of the wall connecting jig 40.

Further, the tongue piece 42c extends below the connecting portion 42 from a position sandwiched between the pair of notches 42b and 42b. As a result, the joint surface between the wall connecting jig 40 and the outer wall panel 30 can be widened while the wall connecting jig 40 is fixed to the frame 32. Therefore, the wall connecting jig 40 is more firmly fixed to the outer wall panel 30, and the temporary scaffold F can be stabilized.
In the present embodiment, it has been described that a pair of notches 42b and 42b are formed at the lower end of the connecting portion 42, but when the wall connecting jig 40 is fixed to the frame 32, it may interfere with the spacer 31e. If not, it is not necessary to form the notch 42b. Further, only one notch 42b may be formed.

Further, as shown in FIG. 3, the connecting portion 42 of the wall connecting jig 40 is located on the back side of the horizontal joint 21 formed between the adjacent outer wall panels 30 when the base portion 41 is fixed to the frame 32. Placed in. As a result, the wall connecting member 10 can be connected to the outer wall 20 without impairing the appearance.

Next, an example of a procedure for fixing the temporary scaffold F to the outer wall 20 via the wall connecting jig 40 will be described with reference to FIGS. 7 (a) to 7 (e). First, as shown in FIGS. 7 (a) and 7 (b), the wall connecting jig 40 is fixed to the upper surface of the frame 32 of the outer wall panel 30 on the lower floor by using the fastening bolts 43. As described above, the counterbore portion 41b is formed in the base portion 41 of the wall connecting jig 40, and the head portion 43a of the fastening bolt 43 is housed in the counterbore portion 41b.
Therefore, when the wall connecting jig 40 is fixed to the upper surface of the frame 32 by the fastening bolt 43, the head 43a of the fastening bolt 43 does not protrude significantly from the upper surface of the base 41. As a result, as shown in FIG. 7C, when the outer wall panel 30 on the upper floor is attached, the bottom surface of the outer wall panel 30 on the upper floor does not interfere with the head 43a of the fastening bolt 43 (FIG. 3). reference).

Subsequently, as shown in FIG. 7D, the mounting bolt B is inserted into the connecting hole 42a of the wall connecting jig 40 and mounted. The mounting bolt B is connected to the support column Fb of the temporary scaffolding F via the wall connecting member 10. As a result, the temporary scaffold F is fixed at a predetermined distance from the outer wall 20 via the wall connecting member 10 and the wall connecting jig 40. At this time, an external force on the temporary scaffold F acts on the connecting portion 42 of the wall connecting jig 40 via the mounting bolt B, but the wall connecting jig 40 has sufficient strength against the external force. Since it has the plate thickness and width dimensions necessary to secure the above, damage such as deformation does not occur.
Finally, when the building is completed, as shown in FIG. 7 (e), after the temporary scaffolding F is removed, the mounting bolt B is removed from the wall connecting jig 40.

Another example of how to attach the wall connecting jig 40 is shown in FIGS. 8 (a) to 8 (d). In this example and subsequent modifications, the same components as those in the above-described embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. As shown in FIGS. 8A and 8B, the wall connecting jig 40 is attached to the outer wall panel 30 on the lower floor with the mounting bolts B attached to the wall connecting jig 40 in advance. After that, the outer wall panel 30 on the upper floor is installed. After the building is completed and the temporary scaffolding F is removed, the mounting bolt B is removed from the wall connecting jig 40.

FIG. 9 shows a modified example of the wall connecting jig 40 of the present invention. In the above-described embodiment, it has been described that the wall connecting jig 40 has a plate thickness and a width dimension necessary for ensuring sufficient strength against an external force applied to the connecting portion 42. On the other hand, the wall connecting jig 40 according to the present modification has a pair of reinforcing ribs 44, 44 extending across the base 41 and the connecting portion 42, and has a wide dimension. .. As a result, the wall connecting jig 40 is configured to secure the necessary strength against the external force applied to the connecting portion 42.
In this modification, the reinforcing rib 44 is formed by a pair of bent portions extending in a line shape. However, as long as the required strength can be secured, the present invention is not limited to forming the bent portion in a line shape. For example, the reinforcing rib 44 may be formed by forming a line-shaped thick portion on the upper surface of the wall connecting jig 40.

FIG. 10 shows a second modification of the wall connecting jig 40 of the present invention. The wall connecting jig 40 according to this modification has bases 41 (two in the example of FIG. 10) fixed to each of both ends of the frame 32, and is integrally configured with extension portions 47 extending from the respective bases 41. A long connecting portion 42 is provided. Then, an elongated hole 45 extending along the horizontal joint 21 formed between the outer wall panels 30 is formed in the long connecting portion 42. Further, a slide member 46 that can slide along the elongated hole 45 is provided between the outer wall panel 30 and the connecting portion 42, and the mounting bolt B is configured to be fixed to the slide member 46. Has been done.

Since the wall connecting jig 40 is connected to the wall connecting member 10 extending from the support column Fb of the temporary scaffolding F toward the outer wall 20, the support column Fb of the temporary scaffolding F is installed at a position facing the wall connecting jig 40. It is desirable to do. However, it may be difficult to install the support column Fb at a position facing the wall connecting jig 40. In the wall connecting jig 40 according to this modification, the slide member 46 can be slid to a position facing the position where the support column Fb can be installed. Therefore, after installing the support column Fb at a suitable position, the wall connecting jig 40 can be connected to the wall. The member 10 can be connected to the wall connecting jig 40, and the temporary scaffold F can be stabilized more reliably.

FIG. 11 shows a third modification of the wall connecting jig 40 of the present invention. In the wall connecting jig 40 according to this modification, two bases 41 are fixed to both ends of the frame 32, and an elongated connecting portion 42 configured as a separate body from the base 41 extends from the base 41. It is arranged in the horizontal direction H over the portion 47. An elongated hole 45 is formed in the connecting portion 42 along the horizontal joint 21. Further, a slide member 46 that can slide along the elongated hole 45 is provided between the outer wall panel 30 and the connecting portion 42, and the mounting bolt B is configured to be fixed to the slide member 46. Has been done. Here, the connecting portion 42 is detachably fixed to the extending portion 47. Therefore, as shown in FIG. 12, the connecting portion 42 may be arranged in the vertical direction E over the extension portion 47 extending from the two base portions 41 provided above and below.
Further, although only one connecting portion 42 is arranged over the two extension portions 47 in FIG. 11, two or more connecting portions 42 may be arranged over the three or more extension portions 47. .. It can be arranged at an appropriate position according to the position and the number of columns Fb of the temporary scaffold F.

By installing the connecting portion 42 in the horizontal direction H or the vertical direction E in this way, after installing the support column Fb of the temporary scaffolding F at a suitable position, the wall connecting member 10 is connected to the wall connecting jig 40. Therefore, the temporary scaffold F can be securely fixed after the position of the temporary scaffold F is determined in advance. Further, when the building is completed and the temporary scaffold F is removed, the connecting portion 42 can be removed together with the removal of the temporary scaffold F. In addition, the elongated hole 45 may not be formed in the connecting portion 42, but a bolt hole may be formed in accordance with the position of the support column Fb of the temporary scaffold F, and the tip of the wall connecting member 10 may be attached.

FIG. 13 shows an outer wall panel member 25 according to this modified example. A plurality of outer wall panel members 25 according to this modification are arranged side by side to form the outer wall 20. The outer wall panel member 25 includes an outer wall panel 30 having a frame 32 arranged at an edge portion, and a wall connecting jig 40 for fixing the wall connecting member 10 for connecting the temporary scaffolding F to the outer wall panel 30 to the outer wall panel 30. Be prepared. The wall connecting jig 40 is the same as the wall connecting jig 40 shown in FIGS. 2 to 6, and the structure of the outer wall panel 30 is different. In the outer wall panel 30, an elongated hole 45 is formed along the longitudinal direction (arrow G direction in the figure) of the frame 32 to be attached. Below the frame 32, a slide member 46 that slides along the elongated hole 45 and is connected to the base 41 of the wall connecting jig 40 is provided. The wall connecting jig 40 connected to the slide member 46 can slide along the elongated hole 45 to change the position of the wall connecting jig 40. After the position is changed, the wall connecting jig 40 is fixed to the frame 32 by, for example, bolting, and the tip of the wall connecting member 10 connected to the temporary scaffold F is connected to the connecting portion 42 of the wall connecting jig 40. NS.

Further, in the above-described embodiment, it has been described that a circular bottom surface 41c is formed with respect to the base portion 41, and a counterbore portion 41b having a cylindrical side surface 41d continuous with the bottom surface 41c is formed. However, the shape of the countersunk portion 41b is not limited to this as long as the head portion 43a of the fastening bolt 43 can be accommodated. For example, it may be a recess having a conical bottom surface 41c, or a recess having a curved mortar-shaped bottom surface 41c. That is, the shape of the bottom surface 41c of the counterbore portion 41b can be appropriately selected according to the shape of the head portion 43a of the fastening bolt 43.

Further, in the above-described embodiment, the reinforcing ribs 44 have been described as forming the reinforcing ribs 44, 44 on a pair of lines at positions sandwiching the insertion holes 41a and the connecting holes 42a from both sides. However, the number of reinforcing ribs 44 is not limited to two. For example, in the case of a wider wall connecting jig 40, two insertion holes 41a and two connecting holes 42a may be formed at positions sandwiched from both sides.
