【The invention's effect】
In the method for constructing a scaffold wall connecting device according to claim 1, the scaffold wall connecting device has a female screw portion formed by cutting an internal thread from one end surface of the columnar body along the axial direction of the columnar body. A round hole having a diameter smaller than that of the female screw is provided from the other end face so as to communicate with the female screw portion, so that a round hole portion is provided. After making more contact, a tapping screw can be inserted from the round hole side to be firmly fixed to the outer wall base material by screwing, and further has the following features.
[0034]
1) It can be attached to any location of the outer wall base material.
2) Since the end surface of the columnar body of the scaffold wall connecting member is fixed to the outer wall base material by abutting the surface, the fixing is stabilized, and the compression and bending strength can be greatly improved.
3) The length of the columnar body is made equal to the thickness of the outer wall to be attached, and the outer end surface and the wall surface are flush with each other, thereby stabilizing the fixing and improving the accommodation of the bolt as the hole closing member. it can.
4) A conventional wall connecting material can be connected and used for the female screw portion, which is versatile.
5) In the installation work using the tapping screw, since the tool is inserted into the inside of the columnar body, the work can be performed without damaging the outer wall with the tool or the like.
6) The bolt as a hole closing member is detachable, so that it can be reused. Even if it is in the attached state, it hardly protrudes outside the outer wall surface. And does not interfere with the work.
[0035]
In the construction method of the scaffold wall tether , the scaffold wall tether is inserted from the round hole side into a mounting hole formed by penetrating the surface material of the outer wall, and abuts the outer wall base material from a right angle direction. In addition, a tapping screw is inserted from the round hole side and fixed to the outer wall base material, and then a male screw portion at an end of the wall connecting material is fixed to a female screw portion of the scaffold wall connecting material by screwing. Since the scaffold is constructed in this way, the fixing is stabilized and the compression and bending strength can be greatly improved.
In addition, a conventional wall connecting material can be connected and used for the female screw portion, which is versatile and can reduce the construction cost.
[0036]
3. The scaffold wall tether according to claim 2, wherein after removing the wall tether, the gap between the mounting hole and the outer periphery of the scaffold wall tether is filled with a waterproof material, and the female screw of the scaffold tether is provided. Since the hole closing member is screwed to the part with a water blocking material interposed, the waterproofing process is complete, and the hole closing member can be attached and detached. Available.
[0037]
In addition, when the hole closing member is a bolt, by suppressing the height of the head of the bolt to a low level, it is possible to eliminate a sense of discomfort with the outer wall surface, and by applying the same color coating to the head, it is more effective. Can be finished.
Therefore, it is suitable as a scaffold wall connecting device and a method for constructing the same.
