Description

[Detailed description of the invention] (a) Technical field The present invention relates to the shape of a connecting part of building boards.

(B) Background Art Conventionally, in the construction of horizontal construction boards as shown in Fig. 1, the female part 7 of the upper member A is connected to the male part 8 of the lower member B, as shown in Fig. 2. hook it to,
There is a method in which the upper part of the upper member is nailed to the stud 9 and stretched over each other, but in the conventional joint shape, the female of the upper member and the male of the lower member are simply latched upwards of the upper member. After the female part was hooked onto the male part, the upper part had to be supported by hand until it was nailed into place.

This caused the following major disadvantages during work at the construction site. In other words, since the main body of the member is usually about 3 meters long and heavy, it is difficult for one person to keep the upper member horizontal while also marking cutting lines, etc., and requires the help of two or more people.

After the parts are horizontally positioned, you cannot let go of your hands supporting them, so you have to drive the nails while supporting them, which requires great skill.

The above does not simply mean that the construction is time-consuming, but it inevitably increases the time and manpower required for construction, which is a factor that increases construction costs.

(c) Purpose of the invention The present invention solves the above-mentioned conventional drawbacks and makes it possible for even one person to easily construct the building boards by preventing them from falling even if the hands are released after connecting them. The purpose is to improve the workability of horizontal construction board materials.

(d) Configuration diagram of the invention Figure 3 shows an embodiment of the construction board material according to the invention. As shown in the figure, the main body C of the member has a male part and a female part for connection at the upper and lower ends, respectively. It has a department.

The male part according to the present invention is an abutting part 1 formed upright from the main body as shown in FIG.
, a locking part 2 which is folded back at an acute angle from the tip of the abutment part 1, and a folded part 3 for facilitating hooking and fitting. Also, the dimensions b and c caused by 1, 2, and 3 are
It is a requirement that c>b.

On the other hand, the female part has a bending part 4 formed by bending the main body downward and a hook part 5 folded back inward to the bending part 4, and the gap between the main body 10 and the tip part 6 is a Then, a is formed to have dimensions such that c>a>b>.

In addition, 4 and 5 are formed to include sufficient space to include the above-mentioned 2 and 3, and after being connected, 5 comes in contact with 2 and serves to prevent the main body from falling. doing. To explain the above relationship in more detail, when the upper member A is connected with a certain degree of inclination toward the builder as shown in Fig. 4, the effective width of the lower member B is b, which is smaller than a of A, but the connection If A is held vertically as shown in Figure 5 and you are trying to fix it by nailing, the effective width of B will be c, which is larger than a, so A will be supported by the locking part 2 of B and will not fall. be.

(E) Effect of the invention As described above, when constructing the construction board according to the invention, after inserting the upper member into the lower member, it is easy to remove the hand to remove a nail or hammer or draw a cutting line. Since the upper part does not fall down, the work can be easily done by one person. This also means that
This also leads to a reduction in construction costs for construction contractors.

As described above, in the present invention, as the male and female connecting parts that fit into each other change the connecting angle of the main body member from the angle when inserted to the angle when fixed, the effective width of the male part inside that fits into each other changes. It is possible to provide a construction board material with excellent workability in which the upper member having the female part does not fall because the insertion width becomes larger than the insertion width of the female part.

Claims (1)

[Scope of claim for utility model registration] (1) In the upper and lower joints of horizontally laid architectural boards,
As the male and female connecting parts, which fit into each other and are connected, change the connecting angle of the main construction board from the angle when inserted to the angle when fixed, the effective width of the inserted internal male part increases and the female A construction board material characterized in that an upper member having a female part does not fall because the width is larger than the insertion entrance width of the part. (2) In the connecting male part of the lower construction board that has already been fixed, the locking part 2 is connected to the abutting part 1.
is provided at an acute angle downward, and a folded part 3 is provided at the tip of the locking part 2 to facilitate hooking and fitting, and the dimensions of each part created by these are b and c, and they will be connected later. The main board 10 is connected to the connecting female part of the upper construction board where
and the tip 6 of the barbed part 5, which is formed so as to include the area below the locking part of the male part, is a, and each dimension of a, b, and c has a relationship of c>a>b. Utility model registration claim No. Architectural board material described in item 1).
