BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold wall connecting device, and more particularly, when constructing a steel frame building, the scaffold installed around it is detachably connected to the steel frame by a connecting rod or the like to be supported. Regarding the wall joining device.

[0002]

2. Description of the Related Art Conventionally, it has been known to assemble a scaffold around its outer periphery as a temporary work for the construction of many structures including steel frame structures. Such scaffolds are usually
Framed scaffolds are used when constructing relatively large structures.

In general, a framed scaffold is a three-dimensional structure formed by assembling each member, and the method of assembling is by arranging the unit frames (Torii type frames) at intervals of the length of the steel scaffolding plate. Attach the cross braces to the, cross over the steel scaffolding board, and fix it with the grips.

The upper and lower parts of the building frame are connected with joint fittings to be built up, and arm locks are attached to prevent the building frame from coming off. After repeatedly solidifying in the horizontal direction in this way, the upper framed scaffolding scaffolds are continuously solidified and the wall ties are framed (steel frame, etc.)
Firmly fixed to.

[0005] By the way, the wall connection in the conventional framed scaffold is basically composed of a connecting fitting detachably attached to the scaffold and a screw rod whose one end is screwed. In addition, such a wall joint is mounted by screwing one end of a screw rod into a connecting fitting and fixing the other end to a steel frame by welding.

[0006]

However, in the conventional wall joint in the scaffold, as described above, since the end of the screw rod is fixed to the steel frame which is the body by welding, the installation work of the wall joint is very difficult. Met. That is, a considerable number of such wall joints are used to prevent the scaffold from collapsing, and the number is extremely large especially when the body is large.

Therefore, it takes a considerable amount of time and labor for welding one screw rod in each wall connection to the steel frame and heating and melting the welded portion when removing these screw rods, which shortens the construction period. It was also a cause of hindering the reduction of construction costs.

The object of the present invention is to solve the above-mentioned conventional problems, and when fixing the wall tie for supporting the scaffolding to the body, the method such as welding is abolished and the time is as short as possible. It is an object of the present invention to provide a wall scaffolding device for a scaffold that can be easily connected to the body.

2, a connecting fitting 13 for connecting to the frame of the scaffold 11 is attached to one end of the connecting rod 12. The connecting rod 12 is a member that connects the scaffold 11 and the steel frame 14 that is the body, and the screw 12a is formed over the entire length thereof.

However, since the most utilized portions of the screw portion 12a formed on the connecting rod 12 are both end portions of the connecting rod 12, the screw 12a is at least the required length at both ends.
May be formed. The connecting fitting 13 attached to one end of the connecting rod 12 is the same as that used in the conventional wall joint, and there is no particular change.

That is, this connecting fitting 13 is used for the scaffolding 11.
It is composed of a split-type joint 13a that is attached to the pipe portion of the frame 11a that is constructed so as to be hugged, and a joint metal fitting 13b attached to this, and one end of the connecting rod 12 is formed on the joint metal fitting 13b. It is screwed into the screw hole and connected.

On the other hand, a clamp 15 is attached to the other end of the bar 12.
Is attached. As shown in FIG. 2, the clamp 15 includes a horizontal U-shaped clamp body 16 in which upper and lower arms 16a and 16b are integrally connected at one side thereof,
The tightening bolt 17 screwed into the screw hole formed in the upper arm portion 16a of the clamp body 16 and the upper arm portion 1
6a and a locking projection 16c integrally formed on the inner surface side of 6a.

A flange plate 16d is attached to the outer surface of the upper arm portion 16a of the clamp body 16 constituting the clamp 15 on the side of the base portion (the end portion on the side of connection with the lower arm portion 16b) by welding or the like. This flange plate 16d
A connecting rod insertion hole is formed in the connecting rod 12, and the connecting rod 12 inserted in this insertion hole is firmly fixed by double nuts 19 and 20, as shown in FIG.

Next, a method of using the scaffold wall connecting device 10 thus constructed will be described. The connecting fittings 13 for connecting to the scaffold 11 and the clamps 15 for connecting to the skeleton are attached to the threaded portions at both ends of the connecting rod 12 in advance using the screws 12 a formed on the connecting rod 12. Then, at the place where the wall connecting device 10 is to be installed, the connecting metal fitting 13 attached to one end of the connecting rod 12 is erected on the scaffold 11.
Attach to a according to the usual method.

After that, the clamp 15 attached to the other end of the connecting rod 12 is connected to the steel frame 14. This clamp 1
For connecting 5 to the steel frame 14, the splice plate 18 is relatively inserted in the space so that the upper arm portion 16a and the lower arm portion 16b of the horizontal U-shaped clamp body 16 sandwich the splice plate 18 of the steel frame 14. Place from the side.

The tip of the upper arm 16a is located where the locking projection 16c formed on the inner surface of the upper arm 16a of the clamp body 16 exceeds the head of the fastening bolt 21 provided on the splice plate 18. Tightening bolt 1
Tighten 7.

As a result, the locking projection 16c formed on the inner surface of the upper arm 16a of the clamp body 16 is locked to the head of the fastening bolt 21 and the fastening bolt 17 is tightened.
By pressing the lower arm 16b to the steel frame 14 by
The clamp 15 will be firmly fixed to the steel frame 14.

Curtain wall construction in such a state (a method of manufacturing the outer wall of a building at a factory and attaching it to the site, by driving sash into a precast concrete plate (PC plate) or aerated concrete plate (ALC plate), The work of attaching and fixing the panel that has been pasted and attached to the frame will be performed. Therefore, it is desirable that the wall connecting device 10 be installed in advance at a position where the connecting rod 12 is inserted through the end-to-end space 23 of the outer wall panel 22.

However, when the position where the wall connecting device 10 is installed is in a state where interference occurs between the connecting rod 12 and the outer wall panel 22, the clamp 15 can be easily removed from the steel frame 14. Therefore, it is very easy to re-install the outer wall panel 22 at the position where the connecting rod 12 passes through the space 23 between the end portions as described above.

[0028]

As described above, according to the scaffold wall joining device of the present invention, the other end of the connecting rod, one end of which is connected to the scaffold, is detachably and surely attached to the steel frame via the clamp. By doing so, it is possible to abolish the welding work that was conventionally performed in this type of construction, it is very easy to attach the wall joining device to the steel frame, and it is possible to significantly reduce the working time and labor. As a result, the construction period can be shortened and the construction cost can be reduced.
