Description

  TECHNICAL FIELD The present invention relates to a rainwater lateral running prevention packing which is used as a waterproofing material for buildings and structures and has enhanced waterproofness at the longitudinal ends of building panels.

  Conventionally, as a joint structure of a building panel that uses this type of rainwater lateral running prevention packing, the male connecting portion of the building panel is simply fixed to the wall base with a fixture such as a tex, and the head of this fixture It was a joint structure in which the female connecting portions were fitted so as to cover each other and the building panels were connected to each other. (For example, refer to Patent Documents 1 and 2).

  However, in the wall body in which the building panel of Patent Documents 1 and 2 is constructed, when rainwater blows into the fitting portion from the vertical joint portion, the rainwater penetrates through the vertical joint portion to the inside of the housing, and the building panel Intrusion into the inside at the end and intrusion into the wall substrate side may have adverse effects such as corrosion on the building panel and wall substrate.

  In order to solve such drawbacks, the present invention is formed of a horizontal portion sandwiched between male and female connection structures of a building panel and a waterproof portion that closes a joint portion between the building panels and has a short shape. It is intended to provide a formed rainwater side-prevention packing.

  According to the rainwater lateral running prevention packing according to the present invention, (1) it is possible to prevent rainwater from running laterally and prevent rainwater from entering the inside of the housing. (2) The waterproofness between the joint portion and the vertical joint portion can be enhanced. (3) The anticorrosion property that prevents the corrosion of the housing can be enhanced. There are features and effects.

  In the following, an embodiment of the rainwater lateral running prevention packing according to the present invention will be described in detail with reference to the drawings. That is, FIGS. 1A to 1C are explanatory views showing a lateral running prevention packing P, FIG. 2 is a sectional view explaining a joint structure using the lateral running prevention packing P, and FIGS. 3 and 4 are for construction. The perspective view which shows the panel A, FIGS. 5-9 is sectional drawing which shows a construction state and construction order, the panel A for construction, the joiner B, the inorganic sheet C, the thermal bridge prevention sheet D, the joint cap E, the water stop It shows a joint structure consisting of packing F, joint packing G, side running prevention packing P, wall base α and fixture β, so-called vertical joint structure.

  First, the members constituting the joint structure will be described. As the building panel A, for example, as shown in FIG. 3 and FIG. This is a building panel A in which a male connecting portion 4 is formed at one end and a female connecting portion 5 is formed at the other end. Reference numeral 1a denotes a box fold piece in which the end portion of the surface material 1 is bent inward.

  The surface material 1 and the back material 2 are thin metal plates such as iron, aluminum, copper, stainless steel, titanium, aluminum / zinc alloy plated steel plate, galvalume steel plate, enamel steel plate, clad steel plate, laminated steel plate (PVC steel plate, etc.), sandwich steel plate (control) Corrugated steel sheets, etc.), vinyl chloride resin, polycarbonate resin, etc. (including color plates coated with various colors, of course) formed into various shapes by roll molding, press molding, extrusion molding, etc., or inorganic materials Formed into various arbitrary shapes by extrusion molding, press molding, autoclave ripening, etc., and the back material 2 is aluminum vapor-deposited paper, asbestos paper, kraft paper, asphalt felt, metal foil (Al, Fe, Pb) , Cu), synthetic resin sheet, rubber sheet, cloth sheet, gypsum paper, aluminum hydroxide paper, glass One such fibrous nonwoven fabric, or those of two or more laminated or waterproof treatment, is made of a sheet material which has been treated flame retardant. Of course, any pattern can be embossed.

  6 is a fireproof sheet, 7 is a waterproof packing, and 8 is a fireproof board.

  Further, the core material 3 is a synthetic resin foam made of polyurethane foam, polyisocyanurate foam, phenol foam, vinyl chloride foam, polyethylene foam, polystyrene foam, urea foam, etc., and mainly the adhesion between the surface material 1 and the back material 2. It functions as an agent and a heat insulating material for the building panel A. Furthermore, various flame retardants can be mixed in the core material 3, and it can also be set as the building panel A which can acquire a fireproof structure and a fireproof structure.

  The integration of the surface material 1 and the back material 2 is performed by the self-adhesiveness of the core material 3.

  The lateral running prevention packing P is formed in a shape that matches the horizontal portion 5a, the convex portion 5b, and the concave portion 5c formed in the male connecting portion 4, and for example, as shown in FIGS. Is formed. The shape is a short shape composed of a horizontal portion 9, a protruding portion 10, and a waterproof portion 11, and a release paper 12 a is formed on the back surface via an adhesive layer 12. Of course, the release paper 12a is peeled off at the time of bonding, and bonded as shown in FIGS.

  As shown in FIG. 4, the lateral running prevention packing P is bonded to the end of the male connecting portion 4 with an adhesive 12. Further, as shown in FIG. 6, the lateral running prevention packing P is formed inside the space γ inside the joint portion 5d shown in FIG. 5, and rainwater travels along the joint portion γ and is located at the vertical joint portion as shown in FIG. It is formed so as not to enter the inside of the housing α, and exhibits waterproofness and a corrosion preventing function of the housing α.

The material is, for example, EPDM, foam rubber, polyvinyl chloride, chloroprene, chlorosulfonated polyethylene, ethylene propylene, asphalt impregnated polyurethane, etc. that are easy to handle and waterproof. is there. In addition, flame retardant materials such as polyphosphoric acid, aluminum hydroxide, phenol resin particles, carbon black, and graphite (foamed and non-foamed) having fire resistance and fire resistance may be mixed in these components.

  Next, the joint structure will be described through a construction example of the building panel A. As shown in FIG. 2 and FIG. 7, the lower construction panel A is first brought into contact with a wall base α made of a steel base (H-type steel, C-type steel, square steel, L-shaped angle, etc.) The building panel A is fixed to the wall base α via the connecting portion 4 via a fixture β such as a tex or screw screw.

  Next, as shown in FIGS. 2 and 7, the head β1 of the fixture β is covered with the lateral running prevention packing P, and then the male type of the lower construction panel A as shown in FIGS. 8 and 9. The female connection portion 5 of the upper building panel A is fitted into the connection portion 4 to connect the building panels A to each other.

  Thus, the lateral running prevention packing P completely fills the space γ in the joint portion γ, thereby preventing rainwater from entering from the outside. Further, since the side running prevention packing P has a shape that completely covers the head of the fixing device β, the hole opened in the building panel A is protected by the fixing device β, and rainwater is introduced into the building panel A from the hole. Can prevent the intrusion.
