Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for fastening an end edge of a rectangular hollow-molded exterior wall board in which a plurality of parallel holes are formed in the longitudinal direction from at least the end face.

[Conventional technology]

In general, hollow-molded exterior wall panels made by extrusion of cement mortar or asbestos-cement mortar, etc.
In order to reduce weight, reduce costs, and improve heat insulation, openings are formed in a line in a plane perpendicular to the extrusion direction, that is, the length direction, of the exterior wall board, as shown in Figure 6. The above hollow molded outer wall board 1
A large number of through holes 2 are provided in parallel to each other in the length direction. Both longitudinal edges 3, 3 of the above-mentioned hollow molded outer wall board 1 have a solid structure or a mutually interlocking structure for the purpose of convenience during construction, waterproof function, etc.

When installing the above-mentioned external wall boards on a building etc., the above-mentioned both end edges 3, 3 are turned horizontally, and the upper and lower edges are engaged and installed upward one after another. As shown in the figure, the outer wall board 1 is fixed to a base 5 such as a column with nails or screws 4 from the surface thereof. However, near the opening of the through hole 2,
If it is fixed with nails or screws, it is likely to be damaged due to expansion and contraction due to temperature changes of the outer wall board or drying contraction due to water absorption. Therefore, it has been necessary to insert nails or screws through the surface of the outer wall board to secure the panel at a distance from the open end, or to drill a long hole and secure the panel in a slidable manner. However, the former method has the disadvantage that the end portion is raised and has a step, which spoils the appearance, while the latter method is not only time-consuming, but also has the disadvantage that water easily enters.

[Problem that the invention seeks to solve]

In view of the above-mentioned circumstances, the present invention has been devised to provide a fastening method that can easily fasten the opening edge of a through-hole in an external wall board with a good appearance and without being damaged by expansion or contraction of the external wall board.

On the other hand, in the second construction method, first, a long hole is bored along the length of the hole in one of the adjacent external wall boards, and a screw is movably inserted into the long hole. After inserting the metal fittings with the screws positioned on the end side so that a portion remains on the end side, one of the external wall boards is placed on the base, and then the other external wall board is placed on one side. Place a predetermined width between the end faces of the external wall board and the hole of one external wall board, and place the metal fittings adjacent to the base with the hole of one external wall board facing the hole of the other external wall board, and then insert the metal fitting into the hole of the other external wall board. , insert the other end of the metal fitting in the longitudinal direction into the hole in the other wall plate, and finally screw the screw located between the above holes into the base to remove the entire metal fitting. This is a construction method in which the material is moved toward the base. Further, in the second construction method, it is desirable that the cross-sectional shape of the metal fitting is semicircular or U-shaped.

[Specific structure and operation of the invention]

The present invention will be explained below with reference to the drawings.

FIGS. 1a, b to 3 a, b are explanatory diagrams of the construction method according to the present invention. Here, outer wall boards 1, 1
When fixing the exterior wall panels 1 to the base 5, there are two methods: first fixing one of the exterior wall panels 1 to the base 5 with a space between the edges of the exterior wall panels 1, In some cases, the other exterior wall board 1 is placed adjacent to the base plate 5 and fastened to the base 5 later.

First, an embodiment of a construction method for fastening the outer wall panels 1, 1 to the base 5 in a state where they are placed adjacent to each other will be described. Figures 1a and b show metal fittings A used in this example.
It is a perspective view and a top view showing an example. Metal fittings A
is a plate with a semicircular cross section, and the outer wall plate through hole 2
It has dimensions that allow it to be inserted freely. A long hole 12 in the length direction of the metal fitting A is bored at the top of the metal fitting A, through which a threaded screw 11 for locking the metal fitting A is inserted. The sum of the distance between the two and the diameter of the threaded screw 11 is the second
As shown in the figure, the gap is smaller than the gap 14 between the opposing edges of the outer wall panels 1, 1.

To fasten the edge of the exterior wall board using this metal fitting A, first pass the screw 11 through the long hole 12, and then
With the metal fitting A positioned within the gap 14, one end of the metal fitting A is inserted into a predetermined through-hole opening of one of the outer wall boards 1. Then, the other end of the metal fitting A enters into the barrier 14 and is inserted so that a part of it remains on the end side of one of the outer wall boards 1. Next, the metal fitting A is moved toward the through hole 2 of the other outer wall plate 1, and the other end of the metal fitting A is inserted into the through hole 2 of the other outer wall plate 1.
Then, the screw 11 located in the gap 14 is screwed to the base 5. As a result, the entire metal fitting A moves toward the base, and the outer wall panels 1, 1 are pressed against the base 5 and fixed. Since the metal fitting A is provided with the elongated hole 12 in this way, it can be moved left and right with the screw 11 passed through it.In this state, one end of the metal fitting A is inserted into the opening, so the metal fitting This prevents the entire part from entering the through hole 2, allowing quick fastening work.

By screwing the screws 11 to the base 5, the metal fitting A is pressed in the direction of the base 5, and the edge of the outer wall board is firmly fixed. Furthermore, even when a strong force is applied due to the expansion or contraction of the board material or the displacement of the external wall boards 1, 1, sliding in the longitudinal direction of the external wall board 1 is possible. The edges will not be damaged due to this.

Next, first place one exterior wall board 1 on the base 5,
An embodiment of a construction method in which the other exterior wall board 1 is later fastened adjacently will be described. In the case of this construction method, the metal fitting A does not satisfy the conditions of the above-mentioned method in which the sum of the distance between the elongated hole end 12a and the metal fitting end 13 and the thread diameter is set smaller than the width of the interval 14, A metal fitting that is longer in the longitudinal direction than metal fitting A is used.

In this construction method, first, one of the adjacent exterior wall panels 1
Insert the metal fitting A into the through hole 2 with the screw 11 positioned on the end surface so that a portion remains on the end surface side. Next, the other outer wall board 1 is placed with a predetermined width 14 between the end faces of the other outer wall board 1, and the through holes 2 of the other outer wall board 1 are made to face each other. and adjacent to the base layer 5. Next, the metal fitting A is moved toward the through hole 2 of the other outer wall plate 1, and the other end of the metal fitting A is inserted into the through hole 2 of the other outer wall plate 1. Finally, the screw 11 located within the space 14
The outer wall boards 1, 1 are fastened to the base 5 by screwing them to the base 5 and moving the entire metal fitting A toward the base 5. And, the same effects as the above-mentioned construction method can be obtained.

In addition, in the above description, the cross section of the metal fitting A is semicircular, but it is not limited to this, and the cross section is U-shaped as shown in FIG.
There is no restriction on the shape of the metal fitting, such as the metal fitting having a rectangular planar shape as shown in FIG.

It is also possible to arrange the metal fittings in FIG. 4a in the opposite direction as shown in FIG. 4b. This may be more convenient as the contact area with the material will be larger.

In the above description, a threaded screw is used, but the present invention is not limited to this, and it is also possible to drill a hole in the base and fasten using a normal screw or a half-threaded screw. Furthermore, although the present invention is applied to a hollow molded exterior wall plate having through holes 2,
Naturally, this method can be adopted as long as at least a plurality of parallel holes are formed in the longitudinal direction from the end face.

〔effect〕

As described above, the construction method of the present invention uses a metal fitting in which a long hole is drilled along the length and a screw is movably inserted into the long hole, so that the entire metal fitting is attached to the end surface of the external wall board. This eliminates the problem of construction problems such as getting stuck in the holes formed in the wall and making it impossible to remove them.Allowing sliding in the longitudinal direction of adjacent exterior wall panels, it can be easily and firmly installed as a base without the need for manpower. It can be fastened to. Moreover, it has many advantages, such as not creating a step between opposing edges and not being damaged due to expansion, contraction, displacement of the outer wall board, etc.
