Description

The present invention relates to a support structure and a support method for a wall material, and more particularly to a support structure and a support method for supporting a wall material (ALC wall material, etc.) that is not necessary for proof stress from below.

The foot of the outer wall facing the common corridor and balcony is a part where water leaks easily. Currently, as a method of preventing water leakage in such a part, it is the mainstream to construct a rising part of concrete at the same time as the floor. However, the method of constructing the rising part of concrete at the same time as the floor is difficult to construct and requires skillful technique, which may affect the construction setup and construction period.

In order to construct the rising part of concrete and the floor separately, after constructing the floor, the rising part of concrete must be constructed on the upper surface. At this time, a structure for fixing the rising portion of concrete to the upper surface of the floor is required.

Various techniques related to the laying structure of PC blocks and anchors for concrete slabs have been disclosed (see, for example, Patent Documents 1 and 2), but these techniques are used when the rising portion of concrete and the floor are constructed separately. Cannot be applied as it is.

The technique described in Patent Document 1 relates to a laying structure of a PC block. In this PC block laying structure, a plurality of bolts are projected from the lower surface of the rectangular PC block. Then, the hole of the fixing bracket is inserted into the bolt, and the nut is screwed through the fixing bracket. Further, on the side surface of the PC block, a joint width holding convex portion that abuts on the side surface of the adjacent PC block and secures the joint width at a predetermined dimension is formed. Further, when the PC block is placed on the flange on the upper side of the joist material, a positioning member having a protruding portion that comes into contact with the end portion of the flange is provided on the fixing bracket. With such a structure, the fixing bracket is rotated to change the protruding direction of the protruding portion of the positioning member, and the position of the PC block with respect to the flange is adjusted. Then, the nut can be screwed in and the flange can be sandwiched between the lower surface of the PC block and the fixing bracket to fix the PC block to the joist material.

The technique described in Patent Document 2 relates to an anchor for a concrete slab. In this concrete slab anchor, a formwork is spread, reinforcing bars are arranged in the formwork, an embedded body is arranged in the formwork and fixed to the reinforcing bars or a cradle, and a through hole for an anchor is formed in the formwork. Then, the position adjusting nut is loosened in advance, the anchor member is inserted into the through hole for the anchor, the retaining portion is hooked on the peripheral edge of the through hole for the anchor, and the position adjusting nut is tightened from above to connect the anchor member and the hook portion. It is said that the embedded body can be fixed securely by adjusting the distance.
