Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a waterproofing structure for a parapet, and can be used for a parapet in a non-walking part such as a flat roof or a front eave.

(Background technology)

2. Description of the Related Art Conventionally, an entrance eave, a window eave, a roof terrace, a balcony, and the like of a building are provided with handrail walls or so-called parapets that rise up to a predetermined height from a bottom surface at a peripheral portion.

In general, a handrail wall such as a balcony is provided with a cap on its upper end surface, and a handrail is further attached.

On the other hand, a rising wall such as a flat roof or an entrance eave is also provided with a cap on its upper end surface.

[Problems to be solved by the invention]

By the way, people always go in and out of Balconi,
Handrails and the like that are good in appearance are required. Therefore, for a walking portion such as a barconi, a cap, a handrail or the like made of an aluminum alloy or the like is used.

However, flat roofs, entrance eaves, and the like are usually non-walking areas where no one can go, and parapets are hardly noticeable. The use of the same shade as the walking part also has various problems for the parapet of the non-walking part.

In other words, parts such as a sash mounting tool are required to mount the sash, and the structure of the sash itself, including the structure of the joints, particularly at the corners, is complicated.

In order to actually attach the cap, the waterproof sheet is welded, and then the cap is attached, and the cap is attached on top. In addition to the complicated structure, there is a problem that installation is troublesome, time-consuming and poor in workability.

In addition, since Kasagi and the like are generally formed by drawing and forming an aluminum alloy or the like, there is a problem that the cost is high and the production cost is high.

An object of the present invention is to provide a parapet waterproofing structure that has a simple configuration, improves workability, and is inexpensive.

[Means for solving the problem]

In the present invention, the waterproof treatment of a non-walking parapet that is not very noticeable does not require the use of a cap, etc. similar to the walking part, and therefore, a waterproof treatment of a simpler configuration is attempted. It is. The specific means is that the rising wall upper surface provided with siding on the side surface is covered with a cover attached via butyl tape,
One end of the cover is fixed to the side surface of the siding, and the other end is provided at a predetermined distance from the side surface of the rising wall opposite to the siding, and the upper surface of the cover is separated from the floor surface following the rising wall. A waterproofing structure for a parapet, which is covered with a waterproof sheet extending along the side surface of the siding, is provided.

[Action]

According to the present invention, the cover with the butyl tape interposed is provided so as to cover the upper end surface of the rising wall having the siding attached to the side surface, and the waterproof sheet adhered along the siding side surface from the floor surface further comprises a waterproof sheet. It is welded to the upper surface to provide a waterproof structure for the parapet.

Therefore, the cover may be attached to the rising wall with butyl tape interposed, and the waterproof sheet may be welded from above,
The simple structure improves workability and reduces cost. In addition, since one end of the cover only needs to be fixed to the siding and can be nailed or the like, the mounting operation becomes easy. Furthermore, the other end of the cover is away from the side of the rising wall,
Since the rising wall upper end surface is waterproof with butyl tape,
Water does not enter, so that there is no need to seal the gap between the other end and the side wall of the rising wall, and the sealing work on that portion is not required. This achieves the above object.

〔Example〕

 Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

The figure shows a partial cross-section of a waterproof structure for a parapet on a flat roof according to the present embodiment.

As shown in the figure, on the periphery of the floor surface (roof surface) 10 of the flat roof, there is provided a low wall, a so-called parapet 11, rising up from the surface by a predetermined height.

Although not shown, the parapet 11 includes a frame having steel beams and columns as elements, an exterior material provided outside the frame, and a siding attached to the frame.
It is composed of 11A etc.

The upper end face 1B of the parapet 11
A cover 12 formed to a predetermined length covering 1B is continuously attached. The cover 12 is made of a member obtained by coating a steel plate with vinyl chloride (hereinafter, referred to as a PVC steel plate).

The cover 12 has a substantially U-shaped cross section, more specifically, a vertical trapezoid cut in the vertical direction, and one side is an inclined side.
It is bent and formed into a U-shape of 12A. And
A paragraph portion 12B is formed substantially at the center of the inclined side 12A.
Further, the cover 12 is slightly wider than the wall thickness of the parapet 11.

Here, the bent one end 12C is siding 11A
When fixed to the parapet 11, the inclined side 12A covers the upper end surface 11B of the parapet 11, and the bent other end 12D is the outer wall 1 of the parapet 11.
It is located at a predetermined distance from 1C.

A butyl tape 13 is attached to the back surface of the cover 12, that is, the surface that comes into contact with the upper end surface 11B of the parapet 11. The butyl tape 13 is provided at a predetermined width from the paragraph 12B of the inclined side 12A and over the entire length of the cover 12.

At approximately the center of the wall thickness of the parapet 11, a fisher plug 14 for mounting the cover 12 is embedded. From the entire floor 10 through the rising part of the parapet 11,
A waterproof sheet 15 is attached to a position about half the thickness of the upper end surface 11B of the parapet 11 with an adhesive or the like. The waterproof sheet 15 is made of vinyl chloride.

Here, the waterproof processing structure 1 of the parapet is constituted by the cover 12, the waterproof sheet 15, the butyl tape 13, the fisher plug 14, and the like.

 Next, the mounting operation of this embodiment will be described.

First, the cover 12 is covered so that the inclined side 12A of the cover 12 formed to have a predetermined length covers the upper end surface 11B of the parapet 11. One end 12C of the bent cover 12 is attached to the side surface of the siding 11A with screws or the like screwed at appropriate intervals. Next, the inclined side 12A is attached to the plug 14 embedded at an appropriate interval with a bolt or the like set with the Fischer plug 14.

After the cover 12 is attached to the entire periphery of the upper end 11B of the parapet 11 on the floor peripheral edge, the waterproof sheet 15 is welded to the upper surface of the cover 12. That is, the waterproof sheet 15 extended from the floor surface 10 to the parapet rising portion and adhered thereto
Is placed on the upper surface of the cover 12 attached to the upper end of the parapet 11 and thermally welded.

According to the present embodiment as described above, the following effects can be obtained.

That is, the cover 12 is an integral type formed by bending, and one end 12C is fixed to the siding 11B with a screw or the like, and the inclined side is formed.
Simply attach the 12A to the fisher plug 14 with bolts or the like. Thus, the structure and the mounting operation are simple. Therefore, workability is improved.

Further, since the cover 12 uses a PVC steel plate and is integrally formed by bending, the material cost and the processing cost are low. Therefore, the cost was low.

Further, after the cover 12 is placed on the parapet 11, the waterproof sheet 15 is heat-sealed and adhered from above the cover 12, so that the screws and bolts attached to the cover 12 are also closed.
There is no leakage of rainwater or the like from the bolts or the like, so that a sufficient waterproof treatment is performed.

In addition, a butyl tape 13 is adhered to a portion where the cover 12 contacts the parapet upper end surface 11B. For this reason, rainwater or the like that is blown up from the outer wall 11C and enters is blocked by the butyl tape, and cannot enter any more. Therefore, the inside of the cover 12 is sufficiently waterproof.

The present invention is not limited to the above-described embodiment, but includes the following modifications.

That is, in the above embodiment, the paragraph 12
B is provided, and the waterproof sheet 15 is welded to the paragraph section 12B. However, the waterproof sheet 15 may be formed on an inclined side having no paragraph section. In this case, the waterproof sheet may be welded to the entire inclined side.

Furthermore, in the above-described embodiment, the present invention is applied to a flat roof, but the present invention is not limited to this, and may be applied to an entrance eave, a window eave, or the like.

In addition, the specific structure, shape, and the like when implementing the present invention may be other structures as long as the object of the present invention can be achieved.
