DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface material used for a floor material, an outer wall material, and the like, and a method of constructing the same.

[0002]

2. Description of the Related Art Conventionally, various types of connecting members have been known which are inserted and installed in gaps between face plate bodies arranged in parallel at a predetermined interval. For example, a backing material made of a foamed polyethylene rod or the like is inserted into the gap between the face material bodies and then filled with a sealing material (prior art 1), and a backer (solid filler) filled into the gap between the face material bodies A) a seal backer having a nonwoven fabric waterproofing sheet adhered to the surface thereof with an adhesive between the face material bodies such as an ALC board (prior art 2), and a water blocking board provided with a watertight material on the back side. One that is inserted and installed in the gap between the body members and fastened and fixed with bolts from the back surface of the body member (prior art 3), One that fills the gap between the body members with a gasket made of a flexible material (conventional technology 4) ), Etc. are known.

A face material (floor material) described in Japanese Patent Application Laid-Open No. 9-41626 is a floor material body formed of a flat waterproof plate material and a floor material formed of a waterproof sheet having elasticity and flexibility. And a material connecting member (prior art 5).

[0004]

However, the above-mentioned prior arts 1 to 5 have the following problems. In prior art 1,
When the face material is used for the floor surface, the sealing material may be broken by a shoe or the like, or the gap between the face material bodies may fluctuate due to thermal expansion and contraction of the face material body, and the seal material may not be able to follow and be cut. In the prior art 2, since the seal backer is attached between the face material main bodies with an adhesive, there is a possibility of peeling. In the prior art 3, there is a problem that since the work of bolting from the back surface is involved, it takes time and effort to perform the construction. In the prior art 4, there is a risk that the gap between the face material bodies fluctuates or the gasket falls off due to thermal contraction of the gasket itself.

Further, in the prior art 5 described in Japanese Patent Application Laid-Open No. 9-41626, the flooring connecting material is formed of a flexible waterproof sheet, so that it breaks when stepped on by shoes or the like, and impairs watertightness. There is a problem.

The present invention has been made in view of the above-mentioned problems, and does not break, peel, or fall off due to external force to impair watertightness, and is easy to construct by work from one side. It is an object of the present invention to provide a face material having a connecting member inserted and installed in a gap between face material bodies, and a method for constructing the face material.

Then, due to the elastic recovery of the pair of legs vertically suspended from the back side of the bridge plate so as to be elastically deformable, a force directed outwardly acts on the locking portion at the tip of the leg. The second watertight material provided on the second member is pressed, and the secondary waterproofing can be further enhanced.

According to the third aspect of the present invention, after the leg and the locking portion of the connecting member are elastically deformed and inserted into the gap between the face material bodies, the bridge plate of the connecting member is connected to the face material body. Since the abutment portion of the connecting member abuts on the back surface side of the main body of the face member with the second watertight material interposed therebetween, the work of attaching the connecting member is performed from one side of the front surface. Easy. Further, the first watertight material is interposed between the cross-linking plate and the front surface corner of the face material body to be watertight, and the second watertight material is used between the locking portion and the rear surface corner of the face material body. Since it is made watertight, the waterproof part is doubled and the watertightness is excellent.
