Description

[Detailed description of the invention] (Industrial application field) This invention is usually called IDETSUKI, and is used as a waterproof base material in the roof construction method of steel frame structures, etc., or as a roof, external wall, floor, etc. that takes advantage of the flat surface. The present invention relates to a connecting roof panel that can be used. (Prior art) Conventionally, as a connecting roof plate for steel frame structures, etc., for example, as shown in Japanese Utility Model Publication No. 49-41625, an eye-shaped rib formed near the end of the roof plate is connected to the edge of an adjacent roof plate. The bent edge is press-fitted and an eye-shaped sheath piece is fitted around the outer periphery to firmly connect the two roof panels, or as in Japanese Utility Model Publication No. 56-2737, the roof panels are forming a leg-shaped rib portion with a roof plate lower surface support edge and a locking portion at one end, and forming a bent edge having a locking portion that engages with the locking portion at the other end; The bent edge is fitted into the leg-shaped rib portion, and the locking portions are engaged with each other, and the horizontal portion of the upper end of the bent edge is fitted into the inclined portion formed at the tip of the lower supporting edge of the roof plate. It is known that roof panels are connected by abutting one side wall of grooves formed on the roof. (Problem to be solved by the invention) However, in the former case, in the conventional connected roof mentioned above, not only is an eye-shaped strip sheath piece required to firmly connect the roof sheets, but also the floating of the roof sheets is caused. Since locking portions for preventing the locking are not provided on the eye-shaped rib portion and the bent edge, there is a problem in that the bent edge after connection is easily pulled out from the eye-shaped rib portion. In the latter case, the bent edge can be prevented from being pulled out, but since no means is provided to prevent the leg-like rib from expanding in the left-right direction, the leg-like There was a problem in that it was not possible to reliably prevent the rib portion from expanding in the left-right direction. This invention forms an uneven structure to prevent floating and spreading at the connecting part of the roof plate, so that the roof plate connecting part can rise and spread without the need for a separate member to strengthen the connection. The object of the present invention is to provide a connected roof panel that can reliably prevent the above. (Means for Solving the Problems) In order to achieve the above object, the present invention forms a leg-shaped rib portion having a lower surface support edge of the roof plate at one end of the roof plate, and a leg-shaped rib portion is fitted to the other end. In the connecting roof panel in which a combined folded edge is formed and the folded edge is fitted to the leg-shaped rib portion to connect the roof panels, one vertical wall portion of the leg-shaped rib portion has a cross section of approximately A groove having an inverted triangular shape and having a locking surface for preventing floating and expansion having a substantially L-shaped cross section or a substantially V-shaped cross section is provided on the upper side, and a substantially reverse cross section that engages with the groove. A protruding strip having a triangular shape and having an approximately L-shaped cross-section or approximately V-shaped cross-section locking surface for preventing floating and expansion is provided on the bent edge for fitting the leg-shaped rib portion. This is a characteristic feature. (Function) When connecting the roof panels A and A , as shown in the first and second figures, the leg-shaped rib portion 1 formed at one end of the roof panel A is adjacent to the leg-shaped rib section 1 formed at the other end of the roof panel A. The locking surfaces 6a, 6 for preventing floating and spreading of the bent edges 7 for fitting the leg-shaped rib portions are fitted.
A locking surface 5 for preventing floating and spreading, in which a protruding strip 6 having a diameter b is provided on the vertical wall portion 1a of the leg-shaped rib portion 1 .
It connects both roof panels A and A by engaging with grooves 5 having grooves a and 5b. In that case, 2nd to 3rd
The bent edge 7 for fitting the leg-shaped rib portion as shown by the arrow in the figure.
The floating prevention locking surfaces 5a and 6b act against the force that tries to push the leg-shaped rib part 1 upward, that is, the floating force, and the force that tries to spread the leg-like rib part 1 in the left-right direction, that is, the spreading force. The expansion-preventing locking surfaces 5b and 6b act against the force, and the floating and expansion of the roof plate connecting portion is reliably prevented. (Example) Figures 1 to 5 show an example of the present invention,
Reference numeral 1 denotes a leg-like rib part having vertical wall parts 1a and 1'a bent at one end of the roof plate A , and a gutter-like part attached to the roof purlin or wall base (not shown) at the lower end. It has an expanded bottom part 2, and the upper end of the vertical wall part 1'a is bent in a substantially horizontal manner, and a roof plate lower surface support edge 3 and a water droplet receiving gutter part 4 having a concave cross section are arranged in series. 5 has a substantially inverted triangular cross section provided on the vertical wall portion 1a, and has a cross section of approximately L on the upper side.

a and an expansion prevention locking surface 5b; 6 is a substantially reverse cross section formed on the bent edge 7 for fitting the leg-shaped rib portion at the other end of the roof plate A ; It is a protruding strip for preventing floating and spreading that has a triangular shape and has a floating preventing locking surface 6a and a spreading preventing locking surface 6b having a substantially L-shaped cross section or a substantially V-shaped cross section on the upper side. Reference numeral 8 denotes a caulking material filled groove provided in the upper part of the bent edge 7, and the groove 8
The inside can be filled with a required caulking material (not shown). Reference numeral 9 denotes an auxiliary locking protrusion provided on the bent edge 7 for fitting the leg-like rib portion, and 10 indicates an auxiliary locking protrusion 9 above the vertical wall portion 1a of the leg-like rib portion 1 so as to be able to be engaged with the auxiliary locking protrusion 9. Auxiliary groove for locking provided in the part,

(Effects) As explained above, according to the present invention, a leg-shaped rib portion having a lower support edge of the roof plate is formed at one end of the roof plate, and a bent edge for fitting the leg-shaped rib portion is formed at the other end. In the connecting roof plate in which the bent edge is fitted to the leg-shaped rib portion to connect the roof plates, one vertical wall portion of the leg-shaped rib portion has a substantially inverted triangular cross section, and A groove is provided on the upper side with a locking surface for preventing floating and spreading having a substantially L-shaped cross section or a substantially V-shaped cross section, and a groove having a substantially inverted triangular cross section that engages with the groove, and the upper side Since a convex strip with a locking surface for preventing floating and spreading having a substantially L-shaped cross section or a substantially V-shaped cross section is provided on the bent edge for fitting the leg-shaped rib portion, the floating and Even if a levitation force and an expansion force act on the connected portion of the roof plate, which is connected by fitting grooves and protrusions to prevent expansion, the levitation force will not be applied to the engagement surface of the locking surface for prevention of levitation. Since the expansion force is blocked by the engagement of the expansion prevention locking surface, floating and expansion at the connecting portion of the roof shingles is reliably prevented, and this is also prevented by other reinforcements. Does not require any parts, etc.
Since it can be made strong with only roof plates, it is economically advantageous.
