Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a horizontal roof structure using a hanging element.
[0002]
[Prior art]
Conventionally, as a horizontal roof structure using a hanging member, for example, there is one as disclosed in Japanese Patent Application Laid-Open No. 2000-64516. This includes a plurality of folded plate roofing materials in which a bent portion that is bent to the upper surface side is formed at the ridge side end portion, and a bent portion that is bent to the lower surface side is formed at the eave side end portion, and an attachment piece to the roof structure A plurality of connecting members formed integrally with a locking portion having folded pieces are arranged at predetermined positions on the roof structure, and the folded plate roof materials adjacent to each other in the roof surface inclination direction are positioned on the ridge side. The connecting member is fixed to the roof structure in a state where the engaging portion of the connecting member is hooked to the bent portion of the eaves side end portion of the folded plate roof material, and the connecting member is positioned on the folded piece and the ridge side of the engaging portion. Hook the bent part of the ridge side end of the folded-plate roof material located on the eave side to the bent part of the eave-side end part of the folded-plate roof material to connect the ridge side and the folded-plate roof material on the eave side By using a specially-shaped suspension for roof construction , To be able to wipe over the eaves side roof member from ridge side, or is dirty footprints such as roofing material during construction, in which as roofing there is no fear of deformation.
[0003]
[Problems to be solved by the invention]
However, in the above prior art, since the roof material is spread from the ridge side to the eave side, not only the shape of the suspension is complicated, but also the engagement portion of the roof material that engages with the suspension, that is, The shape of the bent portion of the eaves side end portion of the roof material located on the ridge side and the bent portion of the ridge side end portion of the roof material located on the eave side become complicated, and each engagement of the roof material with the hanging element There was a problem that the engaging operation of the part was troublesome and the workability was very bad. In addition, the engagement state in each engagement portion of the roof material is that the horizontal piece front end portion of the bent portion at the eave side end portion is in contact with the lower surface of the bent portion at the ridge side end portion. In addition to the possibility of rainwater entering the engaging portion due to capillary action, the bent portion at the end of the ridge has a substantially S-shaped cross section, so its elasticity is weak and its resistance to wind pressure and impact is low. At the same time, there is a problem that a high rain effect cannot be expected in the engaging portion as a whole.

【The invention's effect】
As described above, the horizontal roof structure of the present invention can easily and surely connect the engaging portion on the eave side of the roofing material and the engaging portion on the ridge side via the hanging member. The locking portion of the roof material and the connection of the engaging portion are bent inward at the lower edge of the locking portion on the eave side to form a mountain-shaped locking piece portion. The engaging portion on the ridge side includes a first engaging portion that engages with the mountain-shaped locking piece portion, first and second bent portions that contact the inner surface of the hanging portion of the locking portion, and a suspension. A rising engagement portion having a substantially M-shaped cross section having a second engagement portion that engages with the engagement portion of the child, and the mountain-shaped engagement piece portion of the engagement portion on the eaves side is Engaging the first engaging portion of the rising engagement portion having a substantially horizontal M-shaped cross section on the side, and the first and second bent portions of the rising engagement portion having a substantially horizontal M-shaped cross section. Locking part on the eaves side Since the connection is performed in contact with the inner surface of the drooping portion, the entire connection portion is securely connected by the resilience and elasticity of the roof material itself, and not only rain water can be prevented from entering from the portion sufficiently. In addition, the structure of the connecting portion becomes stronger in strength, and the strength against wind pressure, impact, etc. is increased.
[0013]
Furthermore, in the present invention, it is possible to prevent rainwater from entering at the connecting portion in the wife direction by the rising edge for forming the ridge provided on the outer edge of the stepped connecting portion, and the overall excellent rain effect It is.
