Description

Description: TECHNICAL FIELD The present invention relates to a method for installing a roof.

2. Description of the Related Art Conventionally, a shingle having two waterproof walls on both side edges is arranged on both sides of a connecting member, and each waterproof wall is engaged with two waterproof adjusting portions formed on both sides of the connecting member. Roofs are known, for example, from JP-A-58-69953 and JP-A-61-183545.

However, in this case, the waterproof walls on both sides of the shingle are bent vertically upward and a plurality of waterproof walls are formed.
Since the waterproof adjustment part only opens downward, when installing, after installing the roof shingle on the ground, attach the connecting material so that the waterproof wall of the roof shingle fits into the waterproof adjustment part on the side Therefore, it is difficult to position the connecting member, and both the roof shingle and the connecting member must be carried on the roof to perform the operation. Furthermore, there is a disadvantage that when the engaging waterproof wall comes into close contact with the waterproof leg piece of the connecting member, rainwater easily enters due to a capillary phenomenon.

In addition, one side of the reinforcing member is fixed to one end of the waterproof plate having inclined standing portions formed on both side edges by welding or the like,
After the reinforcing member is fixed to the ground, the side of the other waterproof plate is welded to the other side of the reinforcing member, and then the cap of the standing portion of these waterproof plates is covered and welded, and the joint portion of the building waterproof plate is welded. A watertight mechanism which can be placed in a hopper is disclosed in JP-A-55-159060.

However, in this watertight mechanism, since the waterproof plate and the reinforcing member, and the waterproof plate and the cap are fixed by welding, not only this fixing work takes time but also when the waterproof plate is laid from one side of the base. In addition, there is a possibility that the dimensions of the waterproof plate and the base may not match on the roofing side. In addition, since the waterproof plate cannot move with respect to the reinforcing member, there is a concern that the waterproof plate may be bent or cracked when the waterproof plate expands and contracts due to a temperature change or the like.

Problems to be Solved by the Invention The present invention solves such disadvantages, simplifies the work of allocating the connecting members and installing the waterproof plate, easily adjusting the dimensional error between the roof foundation and the waterproof plate, and It is an object of the present invention to provide a roof construction method in which a waterproof plate can be easily replaced in a roof.

Means for solving the problem The roof construction method of the present invention is a waterproof plate storage space that is opened downward and outward, a plurality of connecting members formed on both sides are attached to the roof foundation at appropriate intervals, Next, a waterproof plate having a rising waterproof wall on both side edges, which is bent outward and upward at its upper end and bent inward, is disposed between the connection members, and then the waterproof plate is inclined. After inserting the rising waterproof wall on one side into the waterproof plate storage space of the connecting member on one side, the rising waterproof wall contacting the connecting member by pressing the other side of the waterproof plate from above is bent inward. Therefore, the rising waterproof wall on the other side is engaged with the waterproof plate storage space of the connecting member on the other side.

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

Also, the edge of the ridge waterproof plate 32 on the side of the engagement drain 321 is overlapped on the edge of the intermediate waterproof plate 31 on the side of the water return engagement wall 302 and connected to each other.

At this time, the gap between the water return engagement wall 302 and the engagement draining part 311 is widely spaced to form a length adjustment part 306, and the edge of the intermediate part waterproof plate 31 and the ridge part waterproof plate 32 is overlapped. A similar space is formed in the portion, which is also the length adjusting portion 306. Then, by changing the length of the length adjusting unit 306, the length of the waterproof plate 3 is adjusted according to the error in the field size.

Then, the eaves engagement member 304 of the eaves waterproof plate 30 and the intermediate waterproof plate 31 is hooked on the upper end of the eaves 2 and the eaves waterproof plate 3
The sliding of the 0 and the middle waterproof plate 31 is prevented.

In the case of a roof with a long eaves ridge spacing, such as a gymnasium, the length of the waterproof plate 3 is adjusted by connecting a plurality of intermediate waterproof plates 31.

In FIG. 14, reference numeral 5 denotes a connecting member for connecting the waterproof plate 3 in the horizontal direction. The connecting member 5 is provided with overhangs 500 on the left and right sides, and the tip of the overhang 500 is bent outward to protrude. Bends to the lower surface to form a sliding curved portion 503, and a side wall is formed on the lower surface of the overhang portion 500.
501 is provided, and a wide waterproof plate storage space 502 is formed by the lower surface of the overhang portion 500 and the outer surface of the side wall 501.

Next, a process of attaching the waterproof plate 3 to the connection member 5 will be described.

First, the interval between the connecting members 5 is determined from the roof base width and the roof finishing material width, and a plurality of connecting members 5 are mounted on the roof base along the gradient direction according to the intervals.

Next, the waterproof plate 3 is disposed between the connection members 5 and the waterproof plate 3
15 is inclined in the width direction as shown in FIG. 15, and the lower rising waterproof wall 303 is inserted into the waterproof plate storage space 502 below the sliding curved portion 503 of the connecting member 5 on one side.

Then, as shown in FIG. 16, when the end of the other rising waterproof wall 303 is pushed down, the outwardly upward bent portion of the other rising waterproof wall 303 becomes the upper surface of the sliding curved portion 503 of the connecting member 5 on the other side. , And is guided by the curved outer surface of the sliding curved portion 503 to move below the overhang portion 500.

Then, when passing through the tip of the sliding curved portion 503, the rising waterproof wall 303 returns to the original shape and the connecting member 5 on the other side.
17, the waterproof plate 3 is horizontal as shown in FIG. Finally, as shown by the arrow in Figure 18,
The waterproof plate 3 is moved laterally to adjust the position.

19 to 21, reference numeral 7 denotes an upper connection member, and reference numeral 8 denotes a connection member cover that covers an upper portion of the connection member 7.

The upper connecting member 7 has a wide lighting glass frame support groove 700 on both lower sides thereof, and is attached to the upper part of the connecting member 5 by bolts.

The connecting member cover 8 has a hanging wall on the lower surface on both sides.
800 is provided and fitted and mounted on the upper part of the upper connection member 7 so as to form a wide upper adjustment space 801 between the side wall of the upper connection member 7 and the hanging wall 800.

Then, the lower ends of both sides of the lighting glass frame 4 are fitted into the lighting glass frame support grooves 700 of the upper connecting member 7, and the upper ends of both sides are fitted into the upper adjustment space 801 to connect the lighting glass frame 4 in the lateral direction.

By the way, actual roof field width dimensions vary widely depending on the building structure, site area, and regional-specific building structure differences, so in order to facilitate roof connection work, it is easy to absorb the field width error dimension. It requires adjustment functions such as standard mounting, plus mounting, and minus mounting.

If the field width is standard, as shown in Fig. 20,
The rising waterproof wall 303 of the waterproof plate 3 is located at the center of the waterproof plate storage space 502 of the connecting member 5, the lower ends of both sides of the lighting glass frame 4 are located at the center of the lighting glass frame support groove 700, and the upper ends of both sides are upper adjustment spaces. Located at the center of 801 respectively.

In the case where the field width is narrow, as shown in FIG. 19, the lower end and the upper end of both sides of the rising waterproof wall 303 and the lighting glass frame 4 approach the center line of the connecting member 5 and the upper connecting member 7, respectively, and are negatively adjusted. If the field width is wide,
As shown in FIG. 21, the rising waterproof wall 303 and the daylighting glass frame 4
The lower end and the upper end of both sides are located near the side edges of the connecting member 5 and the upper connecting member, respectively, so that plus adjustment mounting is performed.

Effect of the Invention As described above, according to the roof construction method of the present invention, since the waterproof plate is fitted between the previously mounted connection members, the position of the connection member is determined according to the field width. Not only is it easy to carry out, but also it is not necessary to carry the connecting member and the waterproof plate on the roof at the same time, so that the work safety is increased.

Further, the rising waterproof wall can be easily engaged with the waterproof plate storage space of the connection member simply by pressing the side end of the waterproof plate from above, so that the work is easy.

Further, since the fixing work such as bolting or welding between the connecting member and the waterproof plate is not required, the efficiency of construction is further improved, and the waterproof plate is joined to the joining member by mere fitting, so that the temperature change The expansion and contraction of the waterproof plate is absorbed, and there is no fear that the waterproof plate is bent or the connection part is damaged, and the waterproof plate can be easily removed when the waterproof plate is replaced.

In addition, since the rising waterproof wall of the waterproof plate does not adhere to the side wall of the connecting member and an appropriate space can be always maintained, there is no possibility of water leakage due to the capillary phenomenon.
