Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a waterproof structure for a sloped roof, and can be used for waterproofing a handrail of a roof balcony, a ridge portion of a roof, etc.

[Background technology]

Recently, in order to shorten the construction period, industrialized housing is known, in which a plurality of units manufactured in advance at a factory are assembled on-site and built. Some of these houses have a roof unit and a terrace unit equipped with a handrail wall arranged to form a terrace called a roof balcony on the roof. Here, the roof unit has a structure including a roof portion having a slope and a rising portion consisting of a handrail wall, and a cap-shaped member such as a cap tree is attached to the rising portion.

It is necessary to perform waterproofing between the cap-shaped member and the sloped roof, but conventionally, a waterproof sheet is attached to each of the cap-shaped member and the roof, the edges of these waterproof sheets are overlapped, and the By gluing and connecting the overlapping parts, two waterproof sheets were connected to waterproof the entire roof.

[Problem to be solved by the invention]

However, the above-mentioned waterproofing treatment involves a wet treatment using an adhesive, which requires a long curing time, and therefore has the drawback of a long construction time. For this reason, there was a demand for a waterproof structure that could be constructed in a shorter period of time and that only required dry treatment.

An object of the present invention is to provide a waterproof structure for a roof that can be quickly waterproofed using only a dry process.

[Means to solve the problem]

The present invention provides a roof by attaching a water return member to the upper edge of a sloped roof, and interposing a flexible waterproof member between a cap-like member and a water return member disposed above the water return member. It constitutes a waterproof structure.

[Effect]

In the present invention, the waterproof member is sandwiched between the water return member and the shade member, and the waterproof member is compressed.

Since the surface of the compressed waterproof member is pressed against the surfaces of the water return member and the shade member, the surfaces of each member are brought into close contact with each other. This prevents water from entering and forms a waterproof structure with good waterproof performance without using an adhesive.

The entrance of this gap 54 is closed with a flexible seal 56 attached to the side wall 50A, and an elongated member 60 such as a bar or a ruler can be inserted therethrough. 41 operations are possible.

Next, waterproofing of the roof will be explained.

First, when assembling the roof units 5 and 6, the roof portion 3,
4 and the rising portion 20, waterproof sheets 25A and 25B are attached respectively. In addition, the roof portion 3,
Attach water return members 24A to the upper edges of 4 in advance,
A waterproof member 24B is attached to the water returning member 24A.

Next, before attaching the Kasagi 50, a plurality of brackets 30 are attached to the top of the rising portion 20 in advance,
Make preparations for installing the Kasagi 50.

Next, align the protrusions 51A and 51B of the cap 50 with the side walls 36A and 36B of the bracket 30,
Apply external force from above Kasagi 50. As a result, the waterproof member 24B is pressed by the Kasagi 50 to compress the waterproof member 24B, and the protrusions 52A, 52B are inserted into the grooves 37A, 37.
B and fit each other. Thereby, the compressed waterproof member 24B is brought into close contact with the water return member 24A and the cap 50 to prevent water from entering.

Note that when the protrusions 51A, 51B move to the grooves 37A, 37B, they are latched by the latching pieces 40A, 40B, and the protrusions 51A, 51B and the grooves 37A, 37B are reliably fitted.

The caps 50 are fitted to all the brackets 30, and the installation of the caps 50 is completed.

In this way, the installation of the Kasagi 50 is done with a simple operation,
Two waterproof sheets (25A and 25B) are connected with a cap 50 or the like to form a waterproof structure for the roof. Therefore, in such a roof waterproof structure, waterproofing of the edge portions of the roof parts 3 and 4 is completed simply by attaching the cap 50.

On the other hand, in order to remove the cap 50, push away the sealing material 56, insert a slender member 60 such as a ruler into the gap 54, apply an upward external force to the operating protrusion 41 with this member 60, and deform the elastically deformable portion 35. Transform. As a result, the groove 37A is removed from the protrusion 52A, the hooking piece 40A is brought into contact with the protruding piece 51A, and the cap 50 is pushed upward, thereby removing the cap 50 (see FIG. 1).

At this time, once the groove 37A is disengaged from the protrusion 52A, even if the external force is removed, the tip of the protrusion 51A will remain on the guide piece 39A.
This prevents the projection 52A from refitting into the groove 37A.

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

That is, the Kasagi 50 can be easily installed,
Just by attaching the cap 50, the waterproof member 24B is brought into close contact with both the water return member 24A and the cap 50 to prevent water from entering, so that the waterproof structure of the roof can be completed easily and quickly.

In addition, a gap 54°5 formed inside both ends of the Kasagi 50
Since the sealing materials 56 and 57 are arranged at the entrances of the holes 5 and 5, sufficient waterproof performance can be obtained.Furthermore, the water returning member 24A and the waterproofing member 24B are placed at the back of the gap 55 where the entrance is on the sloped roof side. Since it has a double waterproof structure, good waterproof performance can be achieved even when the top slope is gentle.

Further, the sealing material 56 is made of a flexible material such as rubber, and by inserting an elongated member 60 such as a ruler into the gap 54 and applying an external force, the fitting between the groove 37A and the protrusion 52A can be released. , so I replaced Kasagi 50 with the rising part 20.
Moreover, since the protrusion 52A is prevented from fitting into the groove 37A again even if external force is removed, the cap 50 can be easily removed even when the number of brackets 30 is large.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and the present invention includes modifications, improvements, etc. within a range that can achieve the purpose of the present invention.

For example, in the above embodiment, the house 1 has a terrace 8 from the roof units 5 and 6 and the terrace unit 7.
The present invention is not limited to this, and may be a house in which a plurality of roof panels are joined together in a joined shape to form a roof such as a gable roof. At this time, a water return member may be attached to the upper end of the roof panel, and a waterproof member 24B may be interposed between the water return member and the shade member covering the ridge.

Furthermore, although the Kasagi 50 is attached to the upright portion 2o with the bracket 3o in a fitting structure, the present invention is not limited to this, and for example, it may be attached directly to the upright portion 20 with screws. Kasagi 5 while pressing 24B
o can be attached to the rising portion 2o. In addition, it is desirable to be able to attach it by simple operations such as applying an external force.

Further, although the waterproof member 24B is fixed to the water return member 24A side, the present invention is not limited to this, and on the contrary, the waterproof member 24B may be fixed to the Kasagi 50 side.

Further, although the waterproof member 24B is formed of butyl rubber combriform, it is not limited thereto, and may be formed of silicone rubber or the like.In short, it may be formed of a flexible and waterproof member.

〔Effect of the invention〕

As described above, the roof waterproofing structure of the present invention has the advantage that waterproofing can be quickly carried out using only dry treatment.
