Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a wall panel jointer, and more specifically to a wall panel jointer for mounting wall panels to a steel frame base, etc.

[Conventional technology]

Conventionally, when attaching wall plates to a steel base, the ends of the horizontal wall plates D, D are aligned with the vertical frame B, which is made up of C-shaped steel A, A facing each other, as shown in Figure 3. However, it is fixed with tapping screws E and E, and the joint part F is filled with a sealant G.

[Problems with the prior art] However, in the case of the above construction, the vertical rim B
However, due to the connection with the wall plates D and D, it is necessary to make two pieces as a pair, and there is little freedom in the allocation of the wall plates D and D. Also, if the wall plate D is an inorganic wall plate, the screws E There were problems such as cracks etc. appearing in the wall plate D due to over-tightening, and joint breaks occurring between the sealing material G and the wall plate D due to expansion and contraction of the wall plate D due to heat etc. .

[The problem that the idea attempts to solve]

In view of the above-mentioned problems, this invention was made with the aim of providing a wallboard jointer that facilitates ground work such as layout, and also allows wallboards to be connected without causing cracks or joint cuts. It is something.

[Technology that led to solving the problem]

That is, in the wall board joiner of this invention, a U-shaped portion for receiving the opposing end surfaces of both wall boards is integrally formed on a substrate having a width extending across the back surfaces of both wall boards that are butted against each other, A connecting member formed on the inner bottom of each of the U-shaped portions is a connecting member formed with protrusions projecting toward the bottom surfaces of each other, and a band-shaped plate having a width that covers the entirety of each of the U-shaped portions, the center of the back surface a protrusion that fits between the bottom surfaces of each of the U-shaped portions, and has an enlarged portion formed at its tip that has a hook-shaped cross section and engages between the protrusions protruding from the inner bottom of each of the U-shaped portions; The cover member has strips formed therein, and an elastic sealing material is provided on the edge of the back surface of the band-shaped plate in the width direction.

〔Example〕

Next, an example of this invention will be described.

FIG. 1 is a sectional view of an embodiment of this invention, and FIG. 2 is a perspective view of the main parts showing the usage state of the embodiment.

The wall board joiner 1 of this invention is a wall board D, which is abutted against each other, and the opposing end surfaces of the wall boards _D , D are placed on a substrate 2 having a width extending over the back surfaces D1, _D1 of the wall boards D, D, which are abutted against each other.
U-shaped portions 3, 3 for receiving D ₂ and D ₂ are integrally formed, and inner bottom portions 4, 4 of these U-shaped portions 3, 3 have protrusions 5, which protrude toward the respective bottom surfaces 4, 4. 5, and a strip plate 6 having a width that covers the entire U-shaped portions 3, 3, and a connecting member 1A formed with a
A is formed with an enlarged part 8 which fits between the protrusions 5, 5 protruding from the inner bottom part 4 of each of the U-shaped parts, and has a hook-shaped cross section at the tip 7A, which engages between the protrusions 5, 5. The cover member 1 has a protrusion 7 formed therein, and elastic sealing materials 9, 9 are provided on the edges of the back surface of the strip plate 6 in the width direction.
It is composed of B.

In the above embodiment, the connecting member 1A may be formed by bending a thin metal plate as shown in the figure, or may be formed by a pultrusion molded body of aluminum light alloy or the like.

Further, the protrusion 7 of the cover member 1B is made of an elastically deformable material, and is integrally molded with the band-shaped plate 6, for example, from plastic or the like.

[Effect]

Using the wall board jointer 1 of this invention, wall board D,
When connecting D, as shown in _{FIG .}
are inserted to connect both wall plates D, D, apply the cover member 1B from the surface, and connect the protrusion 7 to the connecting member 1A,
If it is pushed strongly between the U-shaped parts 3, 3 of 1A, the hook-shaped enlarged part 8 at the tip is locked between the protrusions 5, 5, so to speak, in a snap-like position.

Further, at this time, the sealing materials 9, 9 on both end edges of the cover member 1B are deformed along the irregularities D3 _{, D4} on the surfaces of the wall plates D, D, thereby imparting waterproof properties.

Furthermore, in the above case, when the wall plate connection part is located exactly on the vertical rim B as shown in the figure, the connection member 1A
are fixed with screws 10 or the like, but even if this is not the case, only connection is possible using the connecting member 1A and the cover member 1B.

〔effect〕

As explained above, this idea allows wallboards to be joined regardless of the position of the vertical rim, and therefore the degree of freedom in allocating wallboard joints is greatly increased, making construction easier and connecting work easier. After connection, a cavity S is formed by the protrusion on the end surface of the wall plate, which has various practical effects such as preventing the accumulation of rainwater etc. that has entered due to capillary phenomenon.
