It is provided. This corner cant material is generally a triangular prismatic member made of expanded polyethylene material or the like, and is adhered to the corners of the rising portion which rises at a right angle.

[0003]

However, it is difficult to finish the corners at a right angle, and burrs are formed at the corners due to the mortar portion that oozes out from the joint of the mold. If a corner cant material is attached with the burr left unattended, the cant material will not be correctly positioned at the corner and the cant material will not be properly adhered. Therefore, at the present time, when the conventional corner cant material is attached, the burr is manually removed. The present invention has been proposed in view of the above, and an object thereof is to provide a corner cant member that can be attached without removing burrs generated at the rising portion.

[0004]

In order to achieve the above object, the present invention is a corner cant material which is disposed at the rising portion of a body having a waterproof layer laid, and which is made of foam synthetic resin and has a rising body. The cross-sectional shape having an upright surface facing the part, a recumbent surface facing the horizontal part of the body, and an inclined surface connecting the both sides forms a substantially triangular shape, and at the corner where the upright surface and the recumbent surface intersect. , A space is provided.

[0005]

In the space provided at the corners of the corner cant material, burrs generated when concrete is poured can be avoided, and it is not necessary to remove the burrs after the concrete is hardened.

According to the curtain plate 8 as described above, the waterproof layer 4 can be pressed by the repulsive force of the elastic material 9, so that the "dripping", "bulging", "peeling", etc. of the waterproof layer 4 can be prevented. Can be prevented.

The corner cant material 3 according to the present invention is made of polystyrene, for example, with a foaming ratio of about 3 to 5, and has a standing surface 20 facing the rising portion of the body and a recumbent body facing the horizontal portion of the body. It is a member having a surface 21 and an inclined surface 22 connecting the both surfaces and having a substantially triangular cross section, for example, a standard length of about 2000 mm and a side of about 35 mm.

According to the embodiment shown in FIG. 2, this corner cant member 3 is provided with a shallow groove-shaped notch 23 on the surface in contact with the slab 1 which is a skeleton and the parapet 2 which is a rising portion, and at the corners. A space 24 is provided. Although the surface in contact with the slab 1 is almost horizontal, the surface in contact with the rising portion is not a vertical surface but is inclined so that a slight gap is formed between the surface and the rising portion. By doing so, even if the side surfaces of the parapet 2 are poorly built, the respective surfaces come into close contact with each other.

In order to dispose the corner cant member 3 as described above, the molten asphalt is poured into the notch 23 so that the recumbent face 21 and the upright face 20 are brought into close contact with the upper and rising wall surfaces of the slab 1. Good. At this time, the corner cant material 3 may be slightly dissolved.

Further, as shown in FIG. 2, a space 2 is formed at the corner.

Therefore, each surface of the corner cant material 3 and each surface of the concrete can be brought into close contact with each other.
Therefore, it is not necessary to remove the burr 25, and the labor can be remarkably reduced. In addition, when molten asphalt is used for the disposition, a waterproofing process in a later step can be performed, so that it is not necessary to apply an adhesive or wait for curing, so that it is possible to shorten the construction time.

FIG. 3 is a sectional view showing another embodiment of the present invention, in which an ALC plate or concrete is used for the floor material 30 and an ALC plate is used for the wall material 31.
That is, the beam member 32 supports the ALC plate or concrete floor member 30. In addition, the supporting metal member 3 provided on the beam member 32
The wall material 31 made of an ALC plate on the frame material 34 connected to 3
Fasten. A post-cast concrete 35 is provided between the end of the floor material 30 and the support metal 33.

Then, the waterproof layer 4 is raised from the floor material 30 to the wall material 31, and the mortar is used to chamfer the corners between the floor material 30 (post-cast concrete 35) and the wall material 31. In this case, the wall material 31 and the floor material 30 behave differently due to the earthquake, and the mortar is broken,
This causes the waterproof layer 4 to break.

Therefore, the corner cant 36 of this embodiment is used.

The recumbent piece 38 facing the horizontal part of 0 and the both pieces 37, 3
The bent shape has an inclined piece 39 connecting the eight. The length of each piece is about 100 mm, the thickness is about 5 to 10 mm, and the standard length is about 2000 mm. The corner cant 36 is made of polystyrene, for example, having a foaming ratio of 3 to 5 and has a predetermined strength and elasticity.

The corner cant 36 having the above structure.
Is disposed at the entering corner formed by the floor material 30 and the wall material 31, and the space 40 is provided at the entering corner. At this time, corner cant 3
It is advisable to bond only the vicinity of both end faces of 6 to the wall material 31 and the floor material 30. By doing so, the waterproof layer 4 is in an insulating state without adhering to the base. Therefore, the behavior at the time of an earthquake can be absorbed in this portion, and the breakage of the waterproof layer 4 can be prevented. Also, even if the post-cast concrete 35 is slightly wet, this part is not used as an adhesive surface,
It leads to shortening the construction period.

In this embodiment as well, it is advisable to cast the molten asphalt into the notches 41 and bond them as in the case of the above-mentioned embodiment, whereby the construction time can be shortened.

Although the present invention has been described above with reference to the illustrated embodiments, the present invention is not limited to the above-described embodiments, but can be appropriately implemented without changing the configuration described in the claims. For example, the space may be formed in any shape. In addition, an adhesive or a double-sided tape may be used when attaching the corner cant material.

[0019]

In summary, the present invention is made of foamed synthetic resin and has an upright surface facing the rising portion of the body, a recumbent surface facing the horizontal portion of the body, and an inclined surface connecting the both sides. The cross-sectional shape is approximately triangular, and a space was provided at the corner where the upright surface and the recumbent surface intersect.Therefore, when forming the upright part, burrs are generated at the corner due to the mortar flowing out from the formwork. Even at the corners that are formed, the corner cant material can be reliably arranged without rising. Therefore, it is not necessary to manually remove the burrs generated at the corners, and the labor can be remarkably reduced, which can contribute to the reduction of the construction period and the labor cost. Moreover, since the synthetic resin foam having a predetermined compressive strength is used instead of the soft sponge-like foam, even if an extruding stress is exerted on the holding concrete, the waterproof layer is hardly broken or damaged.
