Description

[Detailed description of the invention] The present invention relates to a structure for attaching architectural boards to a base material, and more specifically, to a structure for attaching building boards such as ceiling panels and wall boards to a base material. 1 are provided with protruding horizontal pieces 2 that protrude laterally outward, respectively, and protruding portions 4 that protrude from the surface of the top horizontal portion 3 are provided on both ends of the top horizontal portion 3 of the joint body 1, respectively. The joint 5 is shaped, and the recess 7 into which the protruding horizontal piece 2 of the joint 5 enters is opened outward at the side end of the construction board 6. Board 6
A butt contact piece 8 that is flush with the surface of the joint 5 is provided so as to protrude outward from the side end, and the joint 5 is nailed with its top horizontal part 3 in contact with the base material 9, and the left and right building blocks are fixed. The recessed portions 7 of the construction plates 6, 6 are inserted over the protruding horizontal pieces 2 of the joint 5, and the butt contact pieces 8, 8 are brought into butt contact with each other, and the left and right architectural plates 6, 6 are assembled.
This relates to a structure for attaching architectural boards to the base material 9 by connecting them and attaching them to the base material 9.

Conventionally, as shown in FIG. 1, left and right architectural boards 6, 6 such as ceiling boards and wall boards are connected to a base material 9 by a joint 5a and attached to the base material 9.

However, when the top horizontal part 3a of the inverted U-shaped joint 5a is brought into contact with the base material 9 and nailed at one point, the joint 5a is tilted as shown in FIG. 1 due to the unevenness of the surface of the base material 9. It will be nailed to the base material 9.

Therefore, in FIG. 1, the building board 6 on the right side is raised,
The left building board 6 is lowered and a step A is created between the left and right building boards 6.6, resulting in an unsightly appearance.

If the joint 5a is attached to the base material 9 with a significant inclination, the construction board 6 will be connected to the joint 5a in a point contact state, and furthermore, the butt abutment portion 8 of the left and right construction boards 6, 6 will be connected to the joint 5a. , 8 could no longer be brought into butt abutment, resulting in a gap at the connecting portion, which would impair airtightness.

The present invention was devised in view of these conventional drawbacks, and its purpose is to provide protrusions at both ends of the top horizontal part of the joint, so that the joint can be maintained even if the surface of the base material is uneven. A construction structure for attaching building boards to the backing material that can be attached to the backing material without tilting, and as a result, the left and right building boards can be connected accurately as expected and airtight. Our goal is to provide the following.

Embodiments of the present invention will be described in detail below with reference to illustrative drawings.

The joint body 1 is formed into an inverted U-shape, and a series of protruding horizontal pieces 2 are formed at the open ends thereof, each of which protrudes laterally outward at a substantially right angle.

A joint 5 is formed by providing protrusions 4 at both ends of the top horizontal portion 3 of the joint body 1, each of which protrudes beyond the surface of the top horizontal portion 3.

The surface of the ceiling board 10, which is an example of the architectural board 6, has a decorative finish.

A recessed portion 7 into which the protruding horizontal piece 2 of the joint 5 can enter is provided at the side end of the ceiling plate 10, with the recess 7 opening outward at the side end.

Further, a butt abutting piece 8 is provided at the side end of the ceiling board 10 so as to be flush with the surface of the ceiling board 10 and protrude outward from the side end.

Then, the joint 5 is fixed with nails 12 with its top horizontal part 3 in contact with the edge 11 as an example of the base material 9, and then the recessed part 7 of the left and right ceiling panels 10 and 10 is inserted into the projection of the joint 5. The left and right ceiling panels 10 and 10 are connected to each other by being attached to the edge 11 by being fitted onto the horizontal piece 2, and the end edges of the abutment pieces 8 and 8 are brought into airtight abutment, thereby connecting the left and right ceiling plates 10 and 10.

In this case, even if the surface of the field edge 11 is uneven, it is straddled by the protrusions 4.4 at both ends of the top horizontal portion 3 of the joint 5, so that the influence of the surface irregularities can be reduced, and the joint 5 can be Edge 1
It is possible to suppress installation at an angle of 1.

Therefore, since the joint 5 can be installed on the edge 11 without tilting, the upper surface 13 of the recessed part 7 of the left and right ceiling panels 10 can be attached to the upper surface of the protruding horizontal piece 2 of the joint 5, as shown in FIG. As a result, the left and right ceiling panels 10.degree. 10 can be installed at approximately the same level, improving the aesthetic appearance.

Moreover, since the end edges of the abutment pieces 8, 8 of the left and right ceiling panels 10 can be brought into surface contact over a wide range, airtightness can be improved.

Furthermore, since the ceiling plate 10 can be brought into surface contact with the protruding horizontal piece 2 at the upper surface 13 of the recessed part 7, the airtightness can also be improved in this respect.

In addition, wall boards such as bathrooms (architectural boards 6) can be used as wall base material (base material 9).
), the present invention can be implemented when installed in

As mentioned above, in the present invention, protrusions are provided at both ends of the top horizontal part of the inverted U-shape, so although this top horizontal part is also nailed at one point, the irregularities on the surface of the base material are also fixed at the top horizontal part. The joint can be nailed to the base material by straddling the left and right protrusions.

Therefore, the joint can be nailed to the base material without being affected by the irregularities of the surface of the base material, and the left and right architectural boards can be connected at almost the same level, airtightness can be maintained, and the connection accuracy of the architectural boards can be maintained. We were able to increase this.
