Description

[Detailed explanation of the idea] [Industrial application field]

TECHNICAL FIELD The present invention relates to a waste board used for connecting roof panels.

[Prior art]

Conventionally, as shown in FIGS. 5 and 6, roof board materials B are connected in the vertical direction by fitting together through a connecting convex portion 1 on the water side end and a connecting recess 2 on the water bottom end. , in the left-right direction, the side edges of roofing board material B′ are scrapboard.
It is inserted and locked into the insertion groove 5' of the connecting body 4' on the surface of A', and the locking piece 6' provided upright on the edge on the water side is inserted and locked on the lower surface side of the connection convex part 1, and the connection is made. ing.

[Problems to be solved by the invention] Conventionally, in order to drain rainwater that has entered through the gap between the fitting portion of the connecting protrusion 1 and the connecting recess 2 due to capillary action, etc. A drainage ditch 9 is provided on the side, but when rainwater that has entered the drainage ditch 9 flows from side to side inside the drainage ditch 9, it flows between the joints between the drainage ditches 9 of the left and right roofing board materials B, causing the waste board.
There was a problem that it flowed into the back side of A′ and rotted the roof. The present invention has been developed in view of the above circumstances, and its purpose is to provide a waste board that can reliably drain rainwater that has entered through the joints of roof board materials.

[Means to solve the problem]

The waste board of the present invention is the back side of the joint on both the left and right sides of the roofing boards B that are joined in the vertical direction by fitting the connection convex part 1 on the water side end and the connection recess 2 on the water side end. It is a waste board placed on the side, and a connecting body 4 is provided on the surface of the waste board main body 3 from the above-water side to the below-water side, and roof board material B is provided between both sides of the connecting body 4 and the waste board main body 1. An insertion groove 5 is formed into which the side end of the roof board is inserted, and a locking piece 6 into which the connecting convex portion 1 of the roofing board material B is inserted and locked is erected on the water side of the connecting body 4 of the waste board body 3. , a water stop part 7 is erected over almost the entire length of the water-side end of the waste board body 3, and the connection recess 2 of the roof board material B is locked to the water-side end of the waste board main body 1. This configuration solves the above problem. [Function] The roof board material B is joined in the left-right direction by the insertion groove 5, the locking piece 6, and the locking part 8 of the waste board A, and a water stop part 7 is provided at the water-side end of the waste board A over almost the entire length. Since it is installed upright, rainwater that enters from the joints of roof board materials B can be reliably drained away by waste board A.
You can prevent it from flowing to the back side. [Example] Roofing board material B is gently bent in the vertical direction,
The end on the water side is folded back toward the surface side to form a bag-shaped connection protrusion 1, and the tip of the connection protrusion 1 is extended to form a drain groove 9 with a substantially U-shaped cross section. The lower end portion is folded back toward the back side to form a connection recess 2 having a substantially U-shaped cross section. The waste board A has a waste board main body 3 bent in a substantially dogleg shape to match the roof board material B, and the surface has an inverted U-shaped cross-sectional connection extending from the above-water side to the below-water side approximately at the center of the left and right sides. The body 4 is spot welded at the bottom and the connecting body 4
An insertion groove 5 is formed between the left and right sides of the board and the surface of the waste board main body 3. There is approximately Z on the water side of the connecting body 4.
A letter-shaped locking piece 6 is fixed by a lower horizontal piece 6b such that the upper horizontal piece 6a projects downward. Further, the water-side end of the waste board main body 3 is bent at a substantially right angle to the front side to provide a water stop part 7, and the water-lower side end is bent at a substantially right angle to the back side to form a locking part. 8 is provided. A plurality of draining ribs 10 are formed in the vertical direction on both left and right sides of the waste board main body 3. The left and right sides of the cap C are bent toward the back side to provide support pieces 11, and the lower end thereof is bent toward the back side to form a U-shaped portion 12. Therefore, in order to connect roof board materials B that are adjacent in the left and right direction using the waste board A, the waste board A is placed on the roof base as shown in Fig. 2, and the roof board materials B ₁ ,
The side ends of B ₂ are inserted into the insertion grooves 5 of the waste board A, and both sides of the locking pieces 6 are inserted into the roof board material.
It is inserted into the connection convex part 1 of B ₁ and B ₂ , and the locking part 8 is inserted into the connection recess 2 of the roof board materials B ₁ and B ₂ on both sides, respectively, and the roof board materials B ₁ and B ₂ are joined together. .
The supporting piece 11 of the cap C is inserted into the insertion groove 5, and the U-shaped portion 12 is inserted into the connecting recess 2 of the roofing board material B.
It is fitted and attached to the locking part 8 of the waste plate A. In this state, the drain grooves 9 at the water-side ends of the roofing boards B ₁ and B ₂ are located between the locking piece 6 of the waste board A and the waterstop part 7. Therefore, even if the rainwater that has entered the drainage ditch 9 flows to the left and right ends, it will flow into the waste plate A, and even if it flows back, it will be dammed by the waterstop part 7 and will flow along the draining rib 10 to the bottom side of the water. Water is drained into the waste plate A and does not flow into the back side of the waste board A. As shown in Fig. 3, the vertically adjacent roof sheet materials B are joined by fitting the connection concave portion 1 of the roof sheet material B ₂ on the water side into the connection convex portion 1 of the roof sheet material B ₁ on the water side. . Gap between connecting protrusions 1 and adjacent draining ribs 1
Waterproof gaskets 13 and 14 are filled between the two.

[Effect of the idea]

The present invention is characterized in that the connecting recess at the underwater side end and the connecting convex part at the above water side end are fitted, and the roof panels are placed on the back side of the joints on both the left and right sides of the roof panels that are joined in the vertical direction. A board, in which a connecting body is provided on the surface of the waste board body from the water side to the water bottom side, and an insertion groove into which the side end of the roof board material is inserted between both sides of the connection body and the waste board body is provided. A locking piece that is inserted and locked into the connecting convex part of the roof board material is erected on the water side above the connecting body of the waste board body, and a water stop is provided at the water-side end of the waste board body over almost the entire length. The section is set upright, and the lower end of the waste board body is provided with a locking part to which the connection recess of the roof board material is locked, so the insertion groove of the waste board body, the locking piece, and the locking part The roof panels are joined in the left and right direction, and a water-stop part is erected over almost the entire length at the water-side end of the shingle body, so rainwater that enters from the joints between the roof shingles is absorbed by the shingle body. It allows for reliable drainage and prevents rainwater from flowing into the back side and causing the roof to rot.
