Description

[0001]
BACKGROUND OF THE INVENTION
The present invention mainly relates to a building board such as an outer wall board for longitudinal connection and a method for joining the building board.
[0002]
[Prior art]
As shown in FIG. 5, the surface of this type of building board (1A) has a pattern in which a plurality of groove-shaped recesses (2A) are usually formed in parallel in a row. The recess (2A) reaches the end of the building board (1A).
In order to construct an outer wall using such a building board (1A), for example, a joining bracket (5A) is attached to the lateral trunk edge (19) fixed to the outside of the wall frame column (18), and the joining bracket is mounted. A pair of upper and lower building boards (1A) are joined and fixed by (5A).
The connection fitting (5A) includes an upper and lower substrate (6A, 7A) and a plate receiving portion (8A) provided integrally between the upper and lower substrates (6A, 7A), and the plate receiving portion (8A) has a cross section. It consists of a human-shaped backbone (9A) and a heel (10A) that extends from the top of the backbone (9A) up and down, and the upper and lower inner sides of the heel (10A) and the upper and lower substrates (6A, 7A) The upper and lower fitting sandwiching portions (11A, 12A) are formed between them.
The connection fitting (5A) is fixed to the horizontal trunk edge (19) by a nail (17) or the like, and the lower and upper edges of the upper and lower building boards (1A, 1A) are attached to the upper and lower fitting sandwiching portions (11A, 12A). The upper and lower building boards (1A, 1A) are joined and fixed to the wall frame.
[0003]
[Problems to be solved by the invention]
In the above conventional configuration, as shown by the arrow in FIG. 6, rainwater or the like flowing down through the recess (2A) of the building board (1A) passes through the recess (2A) at the lower end of the building board (1A). There is a problem that it penetrates into the joint fitting (5A) and further penetrates into the inside of the wall.
[0004]
[Means for Solving the Problems]
As a means for solving the above-described conventional problems, the present invention provides a building board (1) main body in which a plurality of groove-shaped recesses (2) reaching the end portion are formed in parallel along the vertical direction on the surface. A building board is provided in which both ends or one end in the vertical direction are cut out from the surface deeper than the depth of the recess (2) to form the fitting protrusion (3).
Further, in the present invention, a joining metal fitting (4) comprising a substrate (5) and a plate receiving portion (6) standing on the substrate (5) and having fitting sandwiching portions (10, 11) on both sides is provided with a base surface. The fitting protrusions (3) of the pair of building boards (1) to be joined are respectively fitted to the fitting clamping parts (10, 11) on both sides of the plate receiving part (6) of the fitting (4). A method for joining the building boards (1) fitted and sandwiched is provided. Then, one or both of the fitting clamp portions (10, 11) of the joint fitting (4) used in the method is placed on the end surface of the fitting projection (3) of the building board (1). It is desirable that a contact piece (15) for horizontally or vertically projecting the building board (1) is provided.
[0005]
[Action]
The building board (1) of the present invention is fitted and clamped to the fitting and holding parts (10, 11) of the plate receiving part (8) of the joint fitting (4) with the fitting protrusion (3) mounted on the base surface. By being caulked, they are joined together and fixed on the ground surface.
Since the fitting protrusion (3) of the building board (1) is formed by cutting out deeper than the groove-like recess (2) on the surface of the building board (1), the recess (2) It is deleted by the notch and does not reach the surface of the fitting protrusion (3). Therefore, in the state where the fitting protrusion (3) of the building board (1) is fitted to the joint fitting (4), naturally the fitting sandwiching portion (10, 10) of the plate receiving portion (6) of the joint fitting (4) is provided. 11) and the surface of the fitting projection (3) of the building board (1) do not have a gap due to the recess (2).
Therefore, rainwater flowing down the recess (2) of the building board (1) does not enter the joint fitting (4).
[0006]
【Example】
1 to 4, the building board (1) is, for example, an outer wall board for longitudinal connection, and is made of a wood fiber reinforced cement board or the like, and has a groove-like recess on the surface. (2) is arranged in parallel with multiple vertical lines.
A fitting projection (3) is formed by notching both ends or one end of the building board (1) in the longitudinal direction from the surface. As shown in FIG. 2, the notch depth D is set to the building board (1). It is set deeper than the depth d of the recess (2) of (D> d). Accordingly, the concave portion (2) of the building board (1) is deleted by the notch at the end portion, and the concave portion (2) or its trace does not exist in the fitting projection (3).
[0007]
FIG. 3 shows a joining bracket (4) for joining the building board (1) and fixing it on the ground surface. The joint metal fitting (4) comprises a substrate (5) and a plate receiving portion (6) erected on the substrate (5), and beads (7, 7) are provided on both upper and lower edges of the substrate (5). 7) is formed, and the plate receiving portion (6) is composed of a pair of upper and lower Γ-shaped receiving plates (8, 9), and the inner side of the receiving plate (8, 9) includes the building plate (1). Fitting holding portions (10, 11) for fitting the fitting protrusions (3) are formed.
Convex strips (12, 13) are formed on the lower side of the edge of the backing plate (8, 9), and a contact surface is provided below the middle of the upper backing plate (8) via a stepped portion. (14) is formed, and on the inner side of the lower receiving plate (9), a contact piece (15) is provided obliquely outward from the surface of the substrate (5).
[0008]
As shown in FIG. 4, the joint metal fitting (4) is connected to the frame column (18) outside the wall frame column (18) by a nail (17), a screw or the like through a nail hole (16) of the substrate (5). ) It is fastened to the horizontal trunk edge (19) passed between. Then, the fitting protrusions (3) of the upper and lower building boards (1) are fitted and held in the upper and lower fitting and holding parts (10, 11) of the plate receiving part (6) of the joint fitting (4).
[0009]
In this case, the end face of the lower fitting projection (3) of the upper building board (1) is contacted with the contact surface (14) of the upper receiving plate (8) of the plate receiving part (6) of the fitting (4). ) And the end face of the upper mating projection (3) of the mating projection (3) of the lower building board (1) is connected to the plate receiving section (6) of the fitting (4). ) Level the plate against the edge of the contact piece (15) on the inner side of the lower receiving plate (9).
[0010]
In the above configuration, as shown in FIG. 2, the notch depth D at the end of the building board (1) is set deeper than the depth d of the recess (2) of the building board (1) ( D> d), the concave portion (2) of the building board (1) is deleted at the end portion, and the concave portion (2) or its trace does not exist in the fitting projection (3).
[0011]
Therefore, as shown in FIG. 4, the fitting projection (3) of the building board (1) fitted and clamped to the upper and lower fitting clamping parts (10, 11) of the plate receiving part (6) of the joint metal fitting (4) And the fitting clamping part (10, 11) of the plate receiving part (6) of the joint metal fitting (4), that is, the upper surface of the fitting projection (3) and the Γ part receiving plate (8, 9). Between the lower surface, there is no gap based on the concave portion (2) of the building board (1) or its trace.
Therefore, as shown by the arrow in FIG. 4, rainwater flowing down through the recess (2) of the building board (1) bypasses the front side of the joint fitting (4) and is placed inside the joint fitting (4). Does not invade.
[0012]
Although the said Example is related with the upper and lower joining part of a building board (1), this invention can also be applied also to the right and left joining part (horizontal joint) of a building board.
[0013]
【The invention's effect】
In the present invention, since the concave portion on the surface of the building board is deleted by the notch when the fitting protrusion is notched, a gap is not formed between the fitting protrusion and the joint fitting, and the building board Intrusion of rainwater and the like from the joint portions is reliably prevented.
