Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a surface structure that constitutes the roof, outer wall, etc. of a building.

(Prior Art) A conventional planar structure of a building will be explained using a vertical roof as an example.

The inventor of this invention has proposed, in Japanese Patent Application No. 1-173105 (filed on July 6, 1999), that both side edges of a hanger are supported and fixed on a fixing member on the body side, and that both side edges of the hanger are A concave groove is formed in the center in the width direction of the upwardly protruding support part formed between them, and an inner gutter is provided on the fixing member to surround the concave groove of the hanger, and the adjacent face plate single member, that is, the vertical roof The locking portions folded back from the bent portions of the opposite edges of the plate are supported on the bottom of the groove of the hanger, and the side plate portions of the pressing member are applied to these locking portions, and the pressing member is used as the cover holding member. Both screws are screwed vertically into the recessed grooves with nuts, and the side plate portions press and fix the locking portions to the bottom of the recessed grooves, and a joint cover is placed between the bent portions of the adjacent roof panels. It has been proposed that the protrusion is engaged and supported by the protrusion of the cover holding member.

In this case, the cross section is The shape is simple, and even if the face plate single member is made of a hard material, thick, or both, it can be easily molded into a desired shape.

11. By tightening a screw such as a bolt fixed to the bottom of the concave groove provided in the support part of the hanger, a screw such as a nut that is screwed into this screw allows the side plate part of the pressing member to engage with the single member of the face plate. engaging the retaining portion, and pressing the retaining portion against the bottom of the concave groove with a large pressing force by the side plate portion of the pressing member;
The hanger and the pressing member can be strongly clamped together without using elastic deformation of the face plate single member, and the face plate single member can be reliably and firmly fixed to the hanger.

(Problems to be Solved by the Invention) In the method previously proposed by the inventor of the present application, the joint gap between the bent portions is closed with a joint cover to protect it from rain.

However, because it is a single-layer rain cover structure with a bent part and a joint cover, and because the rain cover structure is a structure in which metal plate members overlap each other, warping of the plate members and the product of the plate members may occur. Due to the precision, gaps may remain between the plate members, and it cannot be said that it is a sufficient rain protection structure.In this regard, the overlapping range of the plate members is extended (for example, see Japanese Patent Application Laid-Open No. 2-136460). Although it is possible to provide sufficient rain protection, it is not possible to achieve sufficient rain protection for the reasons mentioned above.

The object of the present invention is to solve the above-mentioned problems and provide a surface structure for a building that can sufficiently block the rain from forming joint gaps.

Another object of the present invention is to provide a surface structure for a building that has good workability and can sufficiently shut off rain by stabilizing an elastic water-stopping material at a required water-stopping site.

Locking of the adjacent face plate single member by a side plate portion bent from the clamping plate portion of the cover holding member and the pressing member toward the hanger side, which are fastened together by a screw provided in the groove and a screw fitted to the screw. Fitting the side plate part between a pressing member whose part is pressed and fixed to the bottom of the groove of the hanger and the bent part of the adjacent face plate single member,
The protrusions protruding from the opposing surfaces of these side plate parts are respectively engaged and retained by protrusions provided on the side plate part which is bent from the tightening plate part of the cover holding member toward the face plate part of the face plate single member. and a joint cover, characterized in that a pressure contact plate portion bent from the upper end of the side plate portion of the joint cover toward the face plate portion is pressed against the same surface plate portion with an elastic water stop material interposed therebetween.

Further, the present invention is characterized in that the pressure contact plate portion of the joint cover has a holding portion recessed in the lower surface of the pressure contact plate, and the upper side of the elastic water stop village is held within the holding portion.

The elastic water stop material is a seal rubber, packing, etc., and is selected as appropriate.

(Function) In the joint cover attached to the joint opening, the protrusion on the side plate is engaged and held by the protrusion of the cover holding member, and the pressure contact plate is pressed against the face plate. An elastic press-contact state is maintained between the press-contact plate portion and the face plate portion of the joint cover using the elastic water-stopping material as a medium.

Since the holding part in the pressure contact plate part holds the upper side of the elastic water stop material, the water stop tube location between the pressure contact plate part and the face plate part is specified, and the water stop tube is positioned at the water stop location and settled.

In addition, the top plate part of the joint cover is formed into a desired cross-sectional shape,
