Description

[Detailed Description of the Invention] The present invention relates to roofing materials for buildings and structures using metal plates, particularly roofing materials that have a partially roofed appearance and have a stepped roofing structure.

Generally, the mainstream methods of roofing using colored iron sheets are tile stick roofing and partial letter roofing, and there are various other methods such as press-formed sheet roofing and corrugated sheet roofing.

Each construction method has its own characteristics, and roofing methods are adopted depending on the intended use.

In particular, in letter roofing, the bottom shape of the roofing material is done by a manual process rather than an industrial process, and the connections are in a seam structure.

As a result, the halves have a close-contact structure that cannot completely prevent capillary action, which has the disadvantage of allowing rainwater to seep into the roof foundation.

In addition, it is necessary to finish the seam structure by tightening the members at the end, and the seam structure is only a mechanical engagement; There were disadvantages such as 1 gutter and rain leaks.

In order to eliminate these drawbacks, the present invention does not use a hook structure for the connection, but simply uses a resting engagement structure, and a joint material with adhesive properties is laminated on the engagement structure to prevent rainwater from flowing from the connection. Completely blocks infiltration, and also completely blocks rainwater from entering through the joints even when working on the roof or under snow loads, and creates gaps for rainwater to infiltrate at the joints even when working on the roof or under snow loads. We propose a roofing material that is completely safe by forming grooves for drainage.

An embodiment of the roofing material according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a perspective view showing one embodiment of the above-mentioned roofing material, and FIG.
is a roofing material that includes a metal roof main body 1, an engaging portion 3 whose upper edge is formed in a U-shape on the front side 2, and a locking portion whose lower edge opposite to the engaging portion 3 is bent into a hook shape toward the back side 4. 5 and a plurality of draining grooves 6 formed over a considerable width at the right end of the main body 1, a joint material 7 filled in at least one of the grooves 6, reinforcing folds 8 and 9. Consists of.

To explain further, the metal roof main body 1 is made by bending the upper and lower ends of a square or rectangular material in the direction of the front and back surfaces, respectively.

In addition, the draining groove 6 has the function of primarily directing rainwater that has entered through the joints (seams) of the roof material A downward (in the needle direction) and as a storage container filled with joint material 7. .

This joint material 7 is used for secondary waterproofing (prevention of capillary phenomenon through complete sealing) and for preventing voids from forming in joints due to loads applied to the roofing material. It is a joint material that has strength and elasticity.

That is, it is a low-foaming joint material made of polyurethane elastomer, which is filled in one of the drainage grooves 6 in liquid or jelly form and sealed with a protective film, and this protective film is removed before use. It is foamed to about 2 to 3 times the size by a chemical reaction, and the curing time is about 24 hours.

Of course, if these are placed in a tube or the like until use and then filled into the drainage groove 6 at the time of use, the protective film is not required.

Next, to explain the case of forming a roof using the roofing material according to the present invention, as shown in Fig. 2, asphalt roofing C is laid on the roofing board B, and the roofing material A is laid as shown in Fig. 3. The engaging part 3 is fixed via a hanger, and then the engaging part 5 of the upper adjacent roof material A' is hooked.

Perform these tasks in order from top to bottom.

Furthermore, as shown enlarged in FIGS. 4 and 5, a gap E is formed in the left and right direction as shown in the cross section.

In other words, the void (
For example, 0.3TrIn) is formed, and its longitudinal cross-sectional view is a mounted connection structure as shown in FIG.

What has been described above is only one embodiment of the roofing material according to the present invention, and as shown in FIG. It is also possible to install a sloped insulation material base on the back side of the roofing material.

As mentioned above, the roofing material according to the present invention is a mounting type that allows the roofing materials to be easily connected, and uses an adhesive foam joint material that forms draining grooves and seals the gaps in the joints. It is completely waterproof and has the characteristic that no voids will be formed in the joints even under the load of solar radiation applied to the roofing material.

Claims (1)

[Scope of utility model registration request] In a roofing material that has an engaging part at the upper end of a rectangular or square metal roof body and a locking part at the lower end, the right end of the roof body is appropriately folded tightly to the width surface side, and the left end is appropriately folded to the width back side. The side is tightly folded, and multiple drainage grooves are formed in the vertical direction over a considerable width from the right side edge, and at least one of the grooves is filled with foam that expands 2 to 3 times and has cushioning properties. A roofing material characterized by being filled with a joint material sealed with a protective film of polyurethane elastomer that forms a body and also has self-adhesive properties when foamed.
