Abstract

(57) [Summary] [Purpose] To prevent roof cracking at horizontal joints in flat roofing materials and to reduce the ratio of upper and lower roof overlap. [Structure] A substantially mountain-shaped protrusion 2 is formed in the front-rear direction at the center of the upper surface of a thin plate made of a corrosion-resistant material, and an upwardly bent part 3 is provided in the width direction at the rear end. Paste sealant 4, 4 on both sides of the horizontal joint member 1.
Configure.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is related to horizontal joint members when layering flat roofing materials such as cement tiles. do.

0002

[Conventional technology]

Among the roofing materials used for building roof construction, clay tiles, thick tiles, cement tiles, etc. As shown in FIGS. 3 and 4, the flat roofing material A has a laminate formed on the side of the roofing material A. The roof parts b and c are overlapped and horizontally spliced, and the upper roof is placed on top of these roofing materials A and A. It is common practice to shift the root material horizontally and layer the roof.

0003

[Problems with conventional technology]

However, flat roofing materials have little undulation, and in order to provide good rain protection, it is necessary to If it is necessary to have a large overlap area, the number of sheets used will increase, and the weight of the roof will increase. Both have the disadvantage of requiring a lot of construction work, and the lap parts b and c in the horizontal joints Since the apparent thickness of roofing material A is only half, cracks are likely to occur at the horizontal joints. There were some shortcomings.

0004

[Problem that the idea aims to solve]

In view of the above-mentioned problems, this idea reduces the overlap ratio of roofing, and also The purpose is to provide horizontal joint members for flat roofing materials that can prevent roof cracking in It was made by

[0005]

[Means to solve the problem]

In other words, the horizontal joint members of the flat roofing material of this invention are made of thin plates made of corrosion-resistant material. A substantially mountain-shaped protrusion is formed in the front-rear direction at the center of the upper surface, and an upward fold is formed at the rear end. A curved portion is provided in the width direction, and a sealing material is pasted on both sides of the protruding portion. It is characterized by being attached.

[0006]

【Example】

Next, an example of this invention will be described. FIG. 1 is a perspective view of an embodiment of this invention, and FIG. 2 is a view of the embodiment in use. That is, the horizontal joint member 1 of the flat roofing material of this invention is made of metal, plastic, etc. It is manufactured by pressing a thin plate made of any corrosion-resistant material. A substantially mountain-shaped protrusion 2 is formed in the front-rear direction at the center of the upper surface of the plate, and an upwardly extending protrusion 2 is formed at the rear end. A bent portion 3 is provided in the width direction, and sealants are provided on both sides of the protruding portion 2. The mounting materials 4, 4 are pasted.

[0007]

[Effect]

If the horizontal joint member 1 with the above configuration is used, adjacent flat roofs can be connected as shown in FIG. Place the rear ends of the roofing materials 5, 5 on the bent portion 3 with the protruding portion 2 in between, and It is possible to perform horizontal splicing with the side end in contact with the protrusion 2, and in this state, the The sealing materials 4, 4 in contact with the lower surfaces of the respective roofing materials 5, 5 seal the horizontal joints. It will be waterproofed. Therefore, the thickness of the flat roofing material 5 is There is no need to provide a thin wrap, which prevents cracks in the roof, and reduces the need for horizontal joints. Waterproofing is ensured by the sealant 4, 4, so the upper and lower roofing materials can be No problem occurs even if the overlapping ratio is lowered.

[0008]

[Effect of the idea]

As explained above, if the horizontal joint member of this invention is used, the horizontal joint members of flat roofing materials can be Is it possible to ensure waterproofing at joints and reduce the need for overlapping of upper and lower roofing materials? As a result, the number of roofing materials used can be reduced, reducing the weight of the roof. At the same time, the number of construction steps can be reduced. In addition, it is possible to prevent roof cracking at horizontal joints. The effect that can be achieved is produced.
