Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a waterproof layer treatment structure for aerated concrete walls.

[Prior art and problems]

Aerated concrete walls, such as handrail structures in buildings, are constructed by providing reinforcement using angles on the indoor side of an aerated concrete slab (hereinafter referred to as ALC), and applying a waterproof layer on the indoor side.

By the way, when constructing the waterproof layer for the handrail wall, because there is a step between the surface of the ALC and the surface of the reinforcing material, it is difficult to treat the edges of the waterproof layer at the boundary between the two. Waterproofing cannot be carried out at the lower part and must be carried out up to the upper surface of the handrail wall, resulting in a problem of high cost for waterproofing.

This idea was made to solve the above problems, and the upper end of the waterproof layer can be treated at the bottom of the handrail wall, reducing the cost of waterproofing the ALC handrail wall. The purpose is to provide a waterproof structure that can be used.

[Means for solving problems]

In order to solve the above-mentioned problems, this idea was developed by burying reinforcing material vertically and reinforcing it with the surface of the aerated concrete wall, where the plate-like parts of the reinforcing material overlap and are exposed on the surface. A horizontal waterproof groove separated by reinforcing material is provided on both sides of the material, and a waterproof layer is layered below the waterproof groove on the surface of the exposed portion of the aerated concrete wall and reinforcement material, and the waterproof groove of this waterproof layer is A rectangular plate whose facing upper end is folded into the waterproof groove and overlapped with the exposed part of the reinforcing material, and which is wider than the waterproof groove and longer than the width of the exposed part of the reinforcing material, and the back side of this rectangular plate. A state in which a frame-shaped part is provided that protrudes from the rectangular plate and is smaller than the width of the exposed part of the reinforcing material and is longer than the width of the exposed part of the reinforcing material, and a waterproof layer that is provided on both ends of this frame-shaped part and overlaps the waterproof layer that overlaps the reinforcing material. A holding fitting is formed by a mounting leg having a width that fits into the space in the waterproof groove in which the waterproof material is folded and a length that overlaps with the bottom of the waterproof groove, and a frame-shaped part of the holding fitting is placed above the reinforcing material. Insert both mounting legs into the waterproof grooves located on both sides of the reinforcing material to fix it to the aerated concrete wall, and apply caulking agent to the outer periphery of the frame-shaped part of this holding bracket and the waterproof grooves. It has a structure in which it is filled continuously.

[Effect]

A horizontal waterproof groove is provided at the bottom of the ALC wall, and the upper end of the waterproof layer provided across the wall and reinforcement material is folded into the waterproof groove.

Stack the horizontally long plate of the presser fitting on the waterproof layer on the reinforcing material, insert both mounting legs into the waterproof groove and fix it to the ALC, and fill the caulking agent continuously around the outer circumference of the presser fitting and inside the waterproof groove. This will ensure complete waterproofing at the boundary between the ALC wall and the reinforcing material, reducing the need for waterproofing and increasing the design freedom of the upper part of the ALC wall.

〔Example〕

Hereinafter, embodiments of the invention will be described based on the accompanying drawings.

As shown in the figure, in the handrail wall formed using ALC1, reinforcing material 2 using angles is buried vertically, and one plate-shaped part of this reinforcing material 2 is exposed in an overlapping state on the indoor surface. .

A horizontal waterproof groove 3 is provided near the bottom of the handrail wall of ALC 1, separated by the reinforcing material 2, and a waterproof layer is placed below the waterproof groove 3 on the indoor side of the handrail wall. 4 is applied, the upper end of this waterproof layer 4 facing the waterproof groove 3 is folded into the waterproof groove 3, and the upper end of the part overlapping with the reinforcing material 2 is folded into the waterproof groove 3.
The height is approximately equal to the upper edge of the.

The reinforcing material 2 and the ALC are attached to the upper end of the waterproof layer 4.
The presser metal fitting 5 used for waterproofing the boundary portion of the material 1 includes a rectangular oblong plate 6 that is wider than the waterproof groove 3 and longer than the width of the exposed portion of the reinforcing material 2, and a rectangular oblong plate 6 on the back side of the oblong plate 6. It is formed of a frame-shaped part 7 that projects in the shape of a frame that is one size smaller than the plate, and a pair of mounting legs 8 that are provided at both ends of the frame-shaped part 7, and is provided in the center of the horizontally long plate 6 so as to protrude toward the back side. A screw hole 10 is bored in the recessed part 9, and this screw hole 1
By screwing the screw 11 inserted into the reinforcing material 2 into the reinforcing material 2 as shown in FIG.

Both mounting legs 8 are set to have a width equal to the width of the waterproof groove 3 minus the thickness of the waterproof layer 4, and are bent toward the opposite sides in the middle, and screw holes 13 are drilled in the bent pieces 12. There is.

To waterproof the upper end of the waterproof layer 4, fold the upper end of the waterproof layer 4 facing the waterproof groove 3 into the waterproof groove 3, and then place the presser metal fitting 5 on the waterproof layer 4 on the reinforcing material 2. , fit the mounting legs 8 on both sides into the waterproof groove 3.

An anchor 14 is buried in advance at the bottom of the waterproof groove 3 provided in the ALC 1 at a position corresponding to the screw hole 13 of the mounting leg 8, and by screwing the screw 15 inserted into the screw hole 13 into this anchor 14, the presser metal 5 is fixed to ALC1. Incidentally, if the fixing strength of the presser metal fitting 5 is required, the center of the horizontally long plate 6 is fixed to the reinforcing member 2 with a screw 11.

By fixing the presser metal fitting 5, the frame-shaped portion 7 becomes the reinforcing material 2.
At the same time, the mounting legs 8, 8 sandwich the upper end of the waterproof layer 4 between the bottom surface of the waterproof groove 3 and the bottom surface of the waterproof groove 3.

Next, when applying caulking agent 16 to the outer periphery of the frame-shaped part 7 and the inside of the waterproof groove 3 on the back side of the presser metal fitting 5 in a continuous manner as shown in FIG. Can be waterproofed.

Incidentally, the space created on the back side of the presser metal fitting 5 and the recessed part 9 of the oblong plate 6 are also filled with caulking agent 16.

In the first example shown in FIGS. 1 to 4, the waterproof groove 3 has a U-shaped cross section, and the bent piece 12 of the mounting leg 8 of the presser metal fitting 5 is arranged so as to correspond to the bottom surface of the waterproof groove 3. However, in the second example shown in FIGS. 5 and 6, the waterproof groove 3
is formed into a substantially V-shape with an inclined bottom surface, and the presser metal fitting 5
The bent piece 12 of the mounting leg 8 shown in FIG.

Further, although not shown in the drawings, waterproofing at the corner portions of the handrail wall where the reinforcing material is exposed in an L-shape can be carried out in the same way as for the straight portions by bending the holding metal fittings 5 to match the corners.

〔effect〕

As described above, according to this invention, the upper end of the waterproof layer of the ALC handrail wall can be waterproofed at the lower part of the handrail wall, and the caulking agent is continuous at the boundary between the ALC and reinforcing agent, greatly improving waterproofness. can be achieved.

Further, since the upper end of the waterproof layer can be waterproofed at the lower part of the handrail wall, the degree of freedom in designing the upper part of the handrail wall can be increased.
