Description

[Detailed description of the invention] This invention forms a standing part by bending each joining side of a plurality of waterproof boards laid in a waterproof part in an inclined manner, and the standing part of each of these adjacent waterproof boards This invention relates to an edge stopper for closing the edges of a waterproof roofing board structure in which the roof panels are sealed together and the apexes of the approximately triangular shapes are fixed.

That is, the gist of this invention is that it is composed of a substantially triangular cylindrical main body that is inserted and fixed into the small end of the splash prevention plate joint, and a face plate that closes the outer end of this main body,
In addition, the top plate and the bottom plate, which constitute one part of the main body, are formed with an elastically absorbing bent part that can expand and contract with respect to the top of the main body at the center along the insertion direction. To provide a stopper for waterproofing the edges of a stepped roof board structure, which can protect the small and small sections from rain and can also respond to changes in expansion and contraction of the waterproof panels due to temperature changes.

Examples of this invention will be described below based on the drawings.

Figure 1 is a perspective view showing the state of the small end waterproof stopper of this invention. In the figure, 1 and 2 are waterproof plates laid in the waterproof part A1, and the joints are respectively Slanted upright pieces 1a and 2a are bent, and these upright pieces 1a and 2a are joined to each other to form a substantially trigonal shape.The top of the joint 3 is fixed by, for example, welding, to form a waterproof roof structure. There is.

The stopper 4 of this invention is inserted into the edge of the joint base [3] and fixed by spot welding W at the upright piece 1a, >a.

Note that B is a cap body that covers the joint portion.

As shown in FIGS. 2 to 4, the stopper 4 of this invention is inserted and fixed into the joint 3. The front plate 6 and the bottom plate 7 forming a part of the main body 5 each have an elastic absorption bending portion 8 which can be expanded and contracted with respect to the top of the main body 5 at the center along the insertion direction. and 9
is formed.

As shown in Section 5 and FIG. 6, these expansion/contraction absorption bending parts 8 and 9 are respectively thrust inward of the main body 5, and are a bending part 8 on the top plate side and a bending part 9 on the bottom side. At the intersection with the bending part 8, the bending part 9
It can be stored in a notch 10 formed in the.

The edge waterproofing stopper 4 of this invention constructed in this way is inserted into the edge side end of the joint 3 of the waterproofing plate 1°2.
Both side plates 5a and 5b of the main body 5 that are in close contact with the upright pieces 1a and 2a of the waterproof plate 1.2 are attached to the upright piece 1 by spot welding W or the like.
This is because it is fixed as a and 2a.

The stopper 4 of this invention is made of a material with excellent water resistance, such as stainless steel, like the waterproof plates 1 and 2, and its molding method is as shown in FIG. 8, for example. It can be formed by punching out, bending along the valley fold line shown by the broken line and the mountain fold line shown by the dashed-dotted line, and bonding the adhesive portion C with an adhesive or the like.

The edge waterproofing stopper of this invention, which is constructed as described above, connects the slanted upright pieces formed on the joint sides of the waterproof boards to each other, and prevents the joints from changing in temperature. It is installed at the edge of a waterproof roofing board structure that is expandable and deformable to prevent rainwater from entering the joint at the edge, and also deforms as the waterproofing board expands and contracts due to temperature changes. Therefore, it has the excellent effect of being able to always perform sufficient rain protection without being affected by the expansion and contraction deformation of the waterproof plate.
