Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure for constructing an outer wall of a building, a structure or the like from a living space (indoor) side.

[0002]

2. Description of the Related Art As a joint structure of this type of outer wall, a backup material (styrene foam) is simply formed between a wood opening surface between building panels (hereinafter referred to simply as "panels") and a base material, or as shown in FIG. As described above, the hat type metal plate b is interposed between the panels a on the wall base α, and then the backup material c
(Or a bond breaker having a peeling function), a caulking material (sealing material) d, etc. are stacked in this order and housed.

[0003]

However, in order to form joints with this kind of structure, it is necessary to construct an outer scaffold, and then construct a protective tape, a sealing material, etc., in that order, and at that time I had to make three round trips between the dirt floors. In addition, the above structure is a structure that can be constructed only from the panel surface side, and due to the concentration of buildings as seen in today's large cities, the location interval between buildings is narrow, and for panel installation on the front side Under the condition that the scaffold cannot be installed, there is a drawback that the above-mentioned conventional joint structure cannot be used.

[0004]

SUMMARY OF THE INVENTION In order to eliminate such drawbacks, the present invention has a fixing piece having a substantially horizontal joiner, a rising piece formed by projecting a substantially central portion of the fixing piece upward, and a rising piece. The cross section is formed in an E shape from a long body with an E-shaped cross section consisting of a waterproof surface protruding from the left and right ends and an elastic packing portion continuously arranged at the lower edge of the waterproof surface. Using the formed joiner, the decorative surface of the mouth end of the panel is arranged so as to be in close contact with the packing part arranged at the lower edge of the waterproof surface of the joiner, and the joint piece is formed by fixing the fixing piece to the back surface of the panel. By doing so, it is possible to perform construction from the indoor side of the building, and yet to propose a joint structure that is rich in waterproofness without losing ordinary mounting strength and workability.

It is a fixed part and is a part for fixing the joiner A. In the figure, a plurality of protrusions 1a protruding along the longitudinal direction are formed in the middle of the fixed piece 1 so that rainwater or the like that has entered can be promptly discharged in the draining direction of the base.

Further, the waterproof surface 4 covers the decorative surface of the panel D and also functions as a fixed base of a packing portion C described later.

The space 5 is a portion for inserting the end of the panel D, which will be described later, to cover the end of the panel D, and is for preventing the end of the panel D from being exposed to the outside.

The packing portion C may be plate-shaped as shown in FIG. 4, or may be rod-shaped, triangular-shaped, trapezoidal-shaped, etc., although not shown. For example, one or more soft synthetic resin foams such as polyurethane may be used. It is formed and has at least elasticity.

When the joiner A is molded by extruding a synthetic resin by utilizing self-adhesiveness or separately by using an adhesive (not shown), it is integrally extruded at the time of extrusion. This is done by doing things. In addition, the packing portion C disposed on the waterproof surface 4 comes into close contact with the decorative surface of the mouth end surface D ₃ of the panel D as shown in FIG.
It mainly functions as a waterproof material, and acts to prevent rainwater or the like, which may enter from the outside, from entering the inside of the substrate.

The core material is composed of a sandwich plate sandwiched between a metal surface material and a back surface material, a particle board, a wood board, and the like, and when forming the joint part γ, the decorative surface of the wood mouth surface D ₃ part is the packing part C of the joiner A. It is disposed on the fixed piece 1 and inserted into the space 5 so as to be in close contact with each other. Of course, these panel D
Can be installed from the back side.

The fireproof substrate E is integrally formed so as to cover the back surface of the joint portion γ, that is, the back surface of the fixed piece 1 of the main body B of the joiner A, and the joint portion γ is covered from the back surface side to form the joint portion γ. The purpose is to improve fire resistance and fire resistance, and the material thereof is a gypsum board or an inorganic board such as rock wool board.

The wall base α is made of a vertically built frame or a base material vertically attached to the frame. For example, a columnar wall formed by welding a C-shaped steel material as shown in FIG. As a base α, in addition to this, H type steel material,
It is also possible to use a steel frame base such as a square steel pipe or a wooden base such as a main pillar or a stud. Further, as the fixing tool β for fixing the fixing piece 1 of the joiner A to the back surface of the panel D, a rivet, a tex, a hex, a screw screw or the like is used.

Next, the construction method of the joint structure according to the present invention will be briefly described with reference to FIG. First, a plurality of panels D ₁ in the n-th row are fixed from the bottom draining to the top sequentially from the back side on the wall foundation α constructed according to the mounting pitch of the panels D. Then, the packing part C of the joiner A is inserted into the space 5 so as to be in close contact with the decorative surface of the mouth end surface D ₃ of the panel D ₁ fixed to the wall base α, and the fixing piece 1 of the joiner A is fixed. One of them is fixed to the back surface of the panel D _{1 from} the back side by a fixing tool β composed of rivets.

After that, the panel D ₂ in the (n + 1) th row is sequentially inserted from the water draining at the lower end to the upper stage, and the end portion is inserted into the space 5 of the fixed joiner A, and the packing portion C is provided with the decorative surface of the mouth end surface D ₃ portion. Work from the back side in the state of abutting and compressing and deforming the packing portion C. After the construction of the panel D ₂ in the (n + 1) th row, the fixing piece 1 is also attached to the back surface of the panel D ₂ in the (n + 1) th row.
Is fixed from the back side with a fixing tool β consisting of rivets, and then
A fireproof base E made of rock wool is continuously formed on the back surface of the joiner A. In this way, the construction is carried out by sequentially constructing each row from the first row to the n-th row. Of course, the panel D is hung by a gondola, a crane, a winch or the like for construction.
The angle F formed on the wall base α is for fixing the panel D.
