Description

[Detailed explanation of the idea] 【Technical field】

The present invention relates to a technique for connecting planar roofing materials with joints.

[Background technology]

The underwater side end of the joint is bent downward to engage with the engaging part of the roofing material on the underwater side,
Since the water side of the joint is placed on the roof base,
In the construction state, a wedge-shaped space is created on the back side of the joint, and for this reason, conventionally, the middle part of the joint was suspended in the air. Therefore, if stepped on, they could easily bend or collapse, causing rain leaks.

[Purpose of invention]

The present invention was developed in view of the above-mentioned technical background, and its purpose is to increase the strength of the joint and prevent rain leaks.

[Disclosure of the invention] The joint for connecting roofing materials according to the present invention has a bent part 3 attached to a joint body 4 for hooking onto an engaging part 2 provided at the above-water side end of the roofing material 1 located below the water. It extends in a substantially U-shape from the lower end of the water to the back side,
It is characterized in that reinforcing sleeve pieces 6 each extend from both side edges of the joint body 4 toward the back side so as to cover the openings on both sides of the space 5 between the back surface of the joint body 4 and the inner peripheral surface of the bent portion 3. Through this, we have achieved the above objective. Embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Reference numeral 1 denotes a horizontal roofing material formed by bending a metal plate, and an engaged portion 7 bent toward the back side in a substantially U-shape is provided on the water-side edge of the roofing material 1. An engaging portion 2 is provided on the edge of the roof material 1 on the water side and is bent toward the surface side in a substantially U-shape. The roofing materials 1 are connected to each other by hooking the engaging portion 2 of the lower roofing material 1. Reference numeral 8 denotes a joint for connecting the left and right roofing materials 1. A tall positioning protrusion 9 is provided in the center of the joint body 4, and a plurality of shorter drainage pipes are provided on both sides of the joint body 4. A protrusion 10 is provided.
A bent portion 3 bent toward the back side in a substantially U-shape is provided at the underwater side end of the joint body 4, and a draining portion 11 is provided upright on the surface of the underwater side end. . Furthermore, reinforcing sleeve pieces 6 extend from both side edges of the joint body 4 toward the back side,
The reinforcing sleeve piece 6 has a triangular shape that is short on the water side and long on the water side, and the openings on both sides of the wedge-shaped space between the back surface of the joint body 4 and the inner peripheral surface of the bent part 3 are the reinforcing sleeve pieces. 6.
This joint 8 is made of polyvinyl chloride, polyethylene,
It is manufactured by continuously extruding an insert material 13 such as aluminum, stainless steel, galvanized iron plate, or steel plate into the center of a resin part 12 such as polypropylene, and then performing secondary processing such as cutting and bending. It is. Then, as shown in Fig. 2, the joint 8 is slid sideways and the bent part 3 of the joint 8 is hooked and engaged with the engaging part 2 of the roofing material 1 on the underwater side. Fit the engaged portion 7 of the roofing material 1 into the bent portion 3 of the joint 8 and the engaging portion 2 of the roofing material 1 on the underwater side thereof, and attach the side ends of the left and right roofing materials 1 to the positioning ridges 9. Connect the left and right roofing materials 1 by inserting them until they touch. By performing construction in this way, the edge of the reinforcing sleeve piece 6 comes into contact with the roof base 14, and even if the joint 8 is stepped on, the joint 8 will not bend or collapse. What is shown in FIGS. 5 and 6 is another example of the present invention, in which a positioning protrusion 9 having a substantially T-shaped cross section is provided at the center of the surface of the joint body 4, and the positioning protrusion 9 is provided after the roofing material 1 is connected. The joint cap 16 can be attached by sliding it. 7, 8, and 9 are still other examples of the present invention, in which a positioning ridge 9 with a mushroom-shaped cross section is provided at the center of the surface of the joint body 4, and a cross-sectional position is provided on the back surface of the joint cap 16. A substantially C-shaped fitting part 15 is provided so that the joint cap 16 can be attached to the positioning protrusion 9 by the fitting part 15.

[Effect of the idea]

Since the present invention is constructed as described, when roofing materials are connected using a joint, the reinforcing sleeve piece of the joint becomes a support between the roof base and the joint body,
This has the advantage that the joints and roofing materials are less likely to deform when stepped on, and are less prone to leaks.

[Brief explanation of the drawing]

Fig. 1 is a perspective view showing one embodiment of the present invention;
The figure is a perspective view of the above joint connected to the roof material on the underwater side, Figure 3 is a partially broken perspective view of the same above joint, Figure 4 is an explanatory diagram of the same construction state, and Figure 5 is A perspective view showing another example of the present invention, FIG. 6 is a partially broken perspective view of the same joint as above, FIG. 7 is a perspective view showing still another example of the present invention, and FIG. 8 is a part of the same joint as above. A broken perspective view and FIG. 9 are cross-sectional views of the same joint cap, in which 1 is a roofing material, 2 is an engaging part, 3 is a bent part, 4 is a joint body, 5 is a space, and 6 is a reinforcing sleeve piece. be.

Claims (1)
