Description

[0001]
[Industrial application fields]
The present invention relates to a metal plate lying roof joint fitting with a positioning mark.
[0002]
[Prior art]
As shown in FIG. 10, the conventional metal plate side roof joint metal fitting is formed with a base material locking collar 30 on the entire lower edge from the front surface to the rear surface side, and on the entire upper edge on the rear surface. A roof plate restraining member 33 having a substantially cross-sectional shape in cross section is provided at the center of the surface of the joint fitting body 32 (joint discard plate) in which the roof plate locking collar portion 31 is formed from the surface to the surface. 33, the side edge portions 36, 36 of the roof plates 35, 35 are inserted into the gap portions 34, 34 between the joint metal fittings 32, and the upper surface thereof is covered with a joint cover body 37 having a required width, and the joint The lower edge flange 38 of the cover body 37 is connected to the base material locking flange 30 at the lower edge of the joint bracket body 32, and the upper edge insertion tongue piece 39 is connected to the roof plate at the upper edge of the joint bracket body 32. Each roof plate 35 is inserted and locked to the locking collar 31. 5 are those that have been joint.
[0003]
[Problems to be solved by the invention]
However, in the above prior art, each part of the joint metal fitting body is composed of three separately formed members of the joint discard plate 32, the roof plate restraining member 33, and the joint cover body 37, so that the number of parts increases, and In addition, the processing is troublesome, and there is a problem that it takes a lot of time in the construction, and the roof plates 35 and 35 are pressed by the restraining force due to the elasticity of the joint cover body 37. When dropped off, there was a problem that the joints of the roof plates 35 and 35 would easily come off.
Furthermore, since the joint metal fitting body of the prior art does not have a bent piece for preventing rainwater intrusion on both the left and right side edges and the upper edge, there is a problem that rainwater cannot enter from the part, Since there is no structure for restricting the amount of insertion of both edges of the roof plates 35 and 35 in the gap portions 34 and 34 of the roof plate holding member 33, both side ends of the roof plates 35 and 35 extend to the back of the gap portions 34 and 34. As a result, the expansion effect of the roof plates 35 and 35 is lost.
[0004]
[Means for Solving the Problems]
The present invention aims to solve the above-mentioned problems, and bends both side edges of a joint metal fitting body made of a thin metal plate of a required size from the front surface to the center of the back surface over a required width to thereby surface the joint metal fitting body. A roof plate holding portion having a required width is formed on the side, and both side edges of the joint metal fitting body are bent outward again on both sides to have a roof plate insertion gap between the roof plate holding portion and the roof plate holding portion. The roof plate holder is formed so as to form a receiving plate portion, and further bend a lower end of the roof plate holding portion to the back side of the roof plate receiving plate portion to form a locking collar portion and surround the roof plate holding portion. Protruding ribs are provided on the plate portion, and the right and left side edges of the roof plate receiving plate portion are bent to the required width surface side to form a bent piece portion for preventing rainwater ingress, and the bent portion for preventing rainwater intrusion The upper edge of the roof plate receiving plate part including one part is on the required width surface side In which characterized in that a positioning mark on both sides of the abutting edges of the roof plate receiving plate portion upper portion with the eaves-like rain water entering prevention bent piece portion by bending.
[0005]
[Action]

The roof plate receiving plate portion includes a bent piece portion for preventing rainwater intrusion by bending the right and left side edges of the roof plate receiving plate portion to the required width surface side to form a bent piece portion for preventing rainwater intrusion. The upper edge of the plate part is bent to the surface side of the required width to prevent intrusion of rainwater Since it is a bent piece part and positioning marks are provided on both sides of the butt edge of the upper part of the roof plate receiving plate part, there is no need for a joint cover body as in the prior art, and the joint Each part of the bracket body, that is, the roof plate retainer and the roof plate receiving plate, is formed of a single plate, so the number of parts can be reduced, processing is easy, and it can be supplied at low cost and labor is also required for construction. In addition, the amount of insertion of the edge of each roof plate into the roof plate insertion gap of the roof plate receiving plate portion can be accurately performed to a predetermined location by the positioning mark, and as a result, the expansion of each roof plate The effect is not lost.
Further, the roof plate receiving plate portion is provided with protruding ribs so as to surround the roof plate holding portion, and rain water invasion preventing bent pieces are provided on the left and right side edges and the upper edge of the roof plate receiving plate portion. Therefore, it is possible to improve the surface reinforcement of the roof plate receiving plate part, that is, to improve the strength against twisting, bending, distortion, etc., and at the same time promote the water retaining action and prevent the intrusion of rainwater from the upper end of the roof plate holding part. Can sufficiently prevent the water around the joint part, and if necessary, a waterproof caulking material is applied to each butt edge of the roof plate receiving plate part to further enhance the waterproof effect. There is an effect such as being able to masquerade.
