Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure around an exterior waist wall in a balcony of a building or an outer corridor, and more particularly to a waterproof structure capable of improving workability.

[0002]

2. Description of the Related Art A structure for mounting a waist wall or fence installed on a veranda or an outer corridor is a structure in which a waist wall panel or fence is supported by a pillar installed upright on the body through a floor of a veranda or the like. It is generally configured to do so.

The procedure for constructing a waist wall having the above-mentioned structure is as follows. After mounting a pillar or a member for supporting the pillar on the body, floor work such as a veranda and waterproofing work are carried out, and then a waist wall is installed. Is being carried out.

[0004]

In the above structure, since the pillars for supporting the waist wall or the supporting members for supporting the pillars are exposed on the floor of the balcony or the like, the waterproofing work for mounting the waterproof sheet on the floor is carried out. In doing so, it is necessary to seal the joint between the waterproof sheet and the exposed member.
However, there is a problem that it is difficult to manage this construction because there is no guarantee that the workability is poor in the field construction and that the sealing can be performed in an accurate manner.

Further, after the waterproofing work is completed, the work for attaching the waist wall or the like to the support is carried out, which causes a problem that it is difficult to carry out the work for the waist wall or the like in a series of steps by the same job. That is, when the waist wall is constructed of panels, the waist wall panel cannot be immediately mounted at the same time as or after the construction of the building wall panel is completed, and the construction cannot be performed between these constructions. There is a problem that the management of the process becomes complicated because the period is entered.

An object of the present invention is to improve the workability and quality of a waterproof layer on a floor such as a balcony, and to perform wall construction and waterproof construction in a series of steps. It is to provide a waterproof structure around.

[0007]

In order to solve the above-mentioned problems, a waterproof structure around a waist wall according to the present invention connects an outer wall and a waterproof inner wall which are arranged in parallel to each other through a support, and connects the waterproof inner wall with a liquid. A waist wall unit constituted by fixing the frame mounting hardware provided through it tightly to the pillar is attached to the body of the building through the frame mounting hardware, and a waterproof layer is provided from the floor of the building to the waist wall unit. The waterproof inner wall is continuously arranged.

[0008]

In the above waterproof structure, the outer wall and the waterproof inner wall are arranged parallel to each other and are joined together through the support, and the waist wall unit in which the frame mounting hardware (mounting hardware) penetrating the waterproof inner wall in a liquid-tight manner is fixed to the support It is attached to the body of the building through the mounting hardware, and a waterproof layer for waterproofing the floor is arranged from above the floor to cover the exposed part of the body and the mounting hardware, and further extend to reach the waterproof inner wall of the waist wall unit. Thus, a continuous waterproof layer can be arranged between the floor and the waist wall unit. Therefore, without forming a notch in the waterproof layer,
It becomes possible to easily manage waterproof construction.

Since the work of attaching the waist wall unit to the body is carried out before the waterproof work is carried out, it becomes possible to carry out the wall work and the waterproof work as a series of steps respectively.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the waterproof structure will be described below with reference to the drawings. 1 is a cross-sectional view for explaining the waterproof structure, is a view taken along the line II of FIG. 2, and FIG. 2 is a plan view for explaining the waterproof structure and the mounting state of the waist wall unit with respect to the body.
II-II arrow view, FIG. 3 is a schematic perspective view illustrating the configuration of the waist wall unit.

First, the constitution of the waist wall unit A is shown in FIG.
~ It demonstrates by FIG. The waist wall unit A is used for a veranda or an outer corridor, and a panel such as siding having a preset height (vertical direction in FIG. 3) is used, and a head tree or a handrail is provided on the upper portion of the panel. When provided, it can be configured as a unit forming a waist wall or a unit forming a handrail. The waist wall unit A is manufactured in a factory in advance, and when it is attached to a building, it is supplied as a finished product.

The waist wall unit A is a siding, a PC
It has an outer wall 1 and an inner wall 2 made of a panel such as a plate and an ALC plate, and a waterproof inner wall 3 is provided between the walls 1 and 2.

The outer wall 1 and the inner wall 2 have the same dimension in the width direction (left and right direction in FIG. 3), and the height is higher than that of the outer wall 1 by the inner wall 2.
Has a smaller value. The walls 1 and 2 are connected to each other by channel-shaped connecting members 4 arranged at both ends with the upper ends of the walls 1 and 2 aligned, and the walls 1 and 2 and the connecting member 4 are formed in a hollow shape. Therefore, the inner wall 2
Is located above the lower end of the outer wall 1.

A square pipe-shaped support 5 having a size smaller than the size of the connection member 4 is fixed to the lower side of each connection member 4, and a bracket 6 serving as a metal for attaching a frame is welded to the support 5 by means such as welding. Is stuck by. The brackets 6 are formed to have a length corresponding to a support metal fitting 14 attached to the body side, which will be described later, and a bolt hole 6a. Are arranged.

The waterproof inner wall 3 has a length equal to the widthwise dimension of each of the walls 1 and 2, and a height dimension corresponding to the height difference between the walls 1 and 2. . The waterproof inner wall 3 is formed of a panel such as a synthetic resin plate or a metal plate, and a hole for penetrating the bracket 6 is formed at a position facing the bracket 6.

The waterproof inner wall 3 has a bracket 6 penetrating through a hole formed in the inner wall 3 and is fixed to an angled mounting member 7 fixed to the bracket 6 by a fastening member 8 such as a bolt or a nut. . That is, the waterproof inner wall 3 is attached to the column 5 via the bracket 6. After the waterproof inner wall 3 is attached to the support column 5, caulking 3a is provided in the gap between the hole and the bracket 6 penetrating the hole. Therefore, the bracket 6 penetrates the waterproof inner wall 3 in a liquid-tight state.

As described above, the waist wall unit A is formed as a hollow member, and a gap is formed between the inner wall 2 and the waterproof inner wall 3 along the longitudinal direction. According to the purpose of the unit A, a cap tree, a handrail or the like (not shown) is attached to the upper end of the waist wall unit A, and the open end of the upper end is closed by these members. However, there is a possibility that rainwater may enter the inside of the waist wall unit A through the gap formed between the inner wall 2 and the waterproof inner wall 3 and fall into the inside of the wall provided below the unit A. For the purpose of avoiding the fear, the inner wall 3
A draining plate 9a is attached below the waterproof inner wall 3 along a gap formed by the waterproof inner wall 3, and a draining plate 9b is attached below the waterproof inner wall 3 and inside the waist wall unit A. .

That is, when the waist wall unit A is applied as a veranda or a waist wall of an outer corridor, a head tree is attached to the open portion at the upper end. Further, when the waist wall unit A is applied as a handrail for a veranda or an outer corridor, the outer wall 1 is configured to have a low height, and a handrail unit is attached to the open portion at the upper end. Further, when it is configured as a handrail, the waist wall unit A may be configured only by the outer wall 1 and the waterproof inner wall 3 without using the inner wall 2.

When forming a veranda or an outer corridor, a plurality of waist wall units A are continuously attached to the body in the width direction or continuously attached to the outer wall of the upper floor. Therefore, it is necessary to waterproof the waist wall units A adjacent to each other. For this reason, it is preferable to previously attach the soft synthetic resin gaskets 10 to the longitudinal end and the lower end of the waterproof inner wall 3 via the joiner.

Next, the waterproof structure when the waist wall unit A is attached to the body will be described with reference to FIGS. In the figure, the outer wall 12 is attached to the beam 11 that constitutes the building frame.
The upper end of the floor is fixed and P that constitutes the floor of the balcony, etc.
A floor plate 13 composed of a C panel, an ALC panel and the like is fixed.

A supporting metal member 14 is fixed to the upper surface of the beam 11 with a space equal to the mounting pitch of the bracket 6 of the waist wall unit A. The bracket 6 is bolted to this support hardware 14.
The waist wall unit A is attached to the skeleton (beam 11) by attaching with the 15a and the nut 15b.

When the waist wall unit A is attached to the beam 11,
The gasket 10 provided at the lower end of the waterproof inner wall 3 is the outer wall 12
It comes into contact with the gasket 10 provided at the upper end of the to exert sealing properties. The draining plate 9b is a gutter 12a provided on the upper end side of the outer wall 12.
The water that has been placed in the upper part of the building and has entered the inside of the waist wall unit A does not permeate into the inside of the building, but is discharged to the outside through the gutter 12a. Furthermore, the outer wall 1 faces the outer wall 12 of the building,
By inserting the gasket 10 into the gap formed between the both, the permeation of water from the outside is prevented.

The beam 11 and the connecting portion between the beam 11 and the waist wall unit A are exposed. Therefore, the waterproof layer 16 is formed from the upper surface of the floor plate 13 on the floor to the waterproof inner wall 3, and the waterproof layer 16 prevents water on the floor from entering the inside of the body.

The waterproof layer 16 is a rigid waterproof layer 16a made of vinyl chloride steel plate formed between the waterproof inner wall 3 of the waist wall unit A and the end of the floorboard 13, and a board laid on the upper surface of the concrete panel 13. A rigid waterproof layer composed of a soft waterproof layer 16b made of a vinyl chloride sheet formed on the upper surface of 17
The flexible waterproof layer 16b and the flexible waterproof layer 16b are integrated with each other by overlapping them by a predetermined size and welding them.

The rigid waterproof layer 16a is formed into a crank shape so that one end thereof is brought into contact with the waterproof inner wall 3 of the waist wall unit A and the bracket 6 can be avoided. Then, the end is brought into contact with the waterproof inner wall 3 and fixed by a screw 18, and then caulking 19 is applied to the end to prevent water from entering the inside of the waist wall unit A from the fixed portion.

When a plurality of waist wall units A are continuously arranged in the width direction, as shown in FIG. 2, the outer wall 1 and the waterproof inner wall 3 are opposed to each other, and the gasket 10 provided on the waterproof inner wall 3 abuts on each other to provide a sealing property. Exert. Further, a gasket 10 is inserted into the gap formed between the outer walls 1 to exert a sealing property and prevent outside water from permeating into the inside of the building.

In the above waterproof structure, the beam 11 and the waist wall unit A
Although there is no member penetrating the waterproof layer 16 in spite of connecting the support metal 14 and the bracket 6 by fastening, it is not necessary to seal around the penetrating member. Therefore, it is possible to exhibit stable waterproof performance. Further, since the waterproof work is performed after the waist wall unit A is attached to the beam 11 in advance, it is not necessary to perform the wall work twice, and the process control can be easily performed.

Even when the waist wall unit A is configured without the inner wall 2 (for example, when a handrail or the like is attached to the upper end portion of the waist wall unit A), the same as above. It is possible to easily carry out waterproofing work.

[0029]

As described in detail above, in the waterproof structure around the waist wall according to the present invention, the waterproof inner wall connected to the outer wall via the support column and the body mounting for liquid-tightly penetrating the waterproof inner wall Since the waist wall unit having a metal fitting is attached to the body through the body mounting hardware to form the waterproof layer extending from the floor of the building to the waterproof inner wall, there is no member penetrating the waterproof layer.

Therefore, the waterproof layer can be made of a series of materials, so that the workability can be improved and a sufficient waterproof function can be exhibited. Further, since the waterproof layer can be constructed after the waist wall unit is attached to the body, it is possible to carry out the wall construction and waterproof construction in a continuous construction period, and in particular, the double labor of the wall construction can be omitted. Therefore, the workability can be improved and the process can be easily controlled.
