Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a wall panel joining structure in which wall panels are joined together by a clamping tool C.

<Conventional Technology> In industrially manufactured houses, ready-made walls (wall panels) are sometimes used for wall construction.

Normally, these wall panels are often connected and joined together. To join wall panels, adhesive is applied to the connecting surfaces of the wall panels to be joined, and after the connecting surfaces are butted together, one This is done by driving a nail diagonally from the surface near the connecting surface of the wall panel to the other wall panel. The bonded wall panels will remain until the adhesive strength develops.
It will be temporarily joined by nailing. Once the wall panels have been joined, an exterior finish is applied to cover the nails used in the joining.

(Problem to be solved by the invention) When joining wall panels, until the adhesive strength of the adhesive is developed,
The wall panels are temporarily joined together by nailing. Therefore,
Finishing to the wall panels had to be done on-site after nailing, which required a large number of on-site construction man-hours.

The present invention has been made in view of the above situation, and provides a wall panel joining structure in which joining is performed using a clamping tool without nailing, thereby realizing on-site joining of finished pile wall panels. The purpose is to improve workability.

Means for Solving the Problems> The structure of the wall panel joining structure according to the present invention to achieve the above object includes: a lower insertion portion opening at the bottom surface on the connecting surface side of the wall panel; a lower fitting in which a pair of protruding pieces to be inserted are formed in the connection direction of the wall panels to regulate the connection position of the wall panels; and an upper fitting part opening on the upper surface of the connection surface side of the wall panels; A clamping tool is formed that is inserted between the upper fitting parts of the wall panels and clamps the upper fitting parts, thereby joining the upper parts of the connection surfaces of the wall panels. .

<Operation> The lower fitting part is inserted into the protruding piece of the lower metal fitting, the lower connecting position of the wall panel is regulated, the upper fitting parts of the wall panels to be connected are clamped by the clamping tool, and the connecting surfaces of the wall panels are held together. are joined.

(Example) Hereinafter, an example of a wall panel joining structure according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a partial sectional view showing a connected state of wall panels using the wall panel joining structure according to the present invention.

A plate-shaped lower metal fitting 3 is attached to the upper surface of the base rail 2 on which the wall panel 1 is placed. Projecting pieces 3a are provided at both longitudinal ends of the base rail 2 of the lower metal fitting 3.

The opposing surfaces of the protruding pieces 3a are sloped surfaces that approach each other as they go downward.

On the bottom surface of the connecting surface side of the two wall panels l that are connected and joined on the base rail 2, there is a lower metal fitting receiver 4 that forms a lower fitting part.
are embedded in each. The end piece of each lower metal fitting receiver 4 on the connecting surface side serves as a claw 4a.

The claw 4a is formed with an inclined surface that is parallel to the inclined surface of the protruding piece 3a when the wall panel l is erected on the lower metal fitting 3. In other words, when the protruding piece 3a of the lower fitting 3 is inserted into the lower fitting receiver 4, the inclined surface of the lower fitting receiver 4 slides down the inclined surface of the projecting piece 3a due to the weight of the wall panel 1, and the connecting surface of the wall panel l The lower parts are close to each other and are in contact with each other.

On the other hand, an upper metal fitting receiver 5 forming an upper fitting portion is embedded in the upper surface of the wall panel l on the connecting surface side. At the upper end of the end piece on the connection surface side of the upper metal fitting receiver 5, a stop claw 6 is formed which is parallel to the upper surface of the wall panel l and extends toward the center of the wall panel l. When the upper portions of the connecting surfaces of the wall panel 1 are brought together, the pawls 6 become back-to-back. A main metal fitting 7, which is a pressing tool and has a U-shaped cross section, is fitted into the back-to-back blind claws 6. The inside of the U-shape of the main metal fitting 7 is a clamping part 7a, and the clamping part 7a clamps the pawls 6 together by elastic force. That is, the upper portions of the connecting surfaces of the wall panel 1 are pressed together through the clamped pawls 6, and the connecting surfaces coated with the adhesive 8 are joined together.

The operation of the above-mentioned wall panel joining structure will be explained.

The lower metal fitting receiver 4 of the wall panel l is inserted into the protruding piece 3a of the lower metal fitting 3 attached to the base rail 2, and the lower portions of the connecting surfaces of the wall panel l come into contact with each other (see FIG. 2). The clamping part 7a of the main metal fitting 7 is driven in with a tool by a tool into the blind pawls 6 which are back to back as the upper parts of the connection surfaces of the wall panels l are aligned (see Fig. 3). are clamped by the elastic force of the main metal fittings 7, and the upper part of the connecting surface of the wall panel l is pressed through the clamped pawls 6. The wall panels l are temporarily joined together, with the main metal fittings 7 maintaining the joining force until the adhesive 8 applied to the connecting surfaces develops the adhesive strength.

According to the above-mentioned wall panel joining structure, the lower metal fitting 3 attached to the base rail 2 and the lower metal fitting 3 provided on the bottom surface of the connecting surface of the wall panel 1 are inserted into the lower metal fitting 3 to abut the lower part of the wall panel 1. It is composed of a lower metal fitting holder 4, an upper metal fitting 5 provided on the upper surface of the connection side of the wall panel l, and a main metal fitting 7 that holds the upper metal fitting holder 5, so that it is easy to drive nails into the wall panel l. It is possible to join wall panels l to each other without having to do so. As a result, it becomes possible to apply finishing to the wall panel 1 in advance, and it becomes possible to perform on-site joining of finished wall panels.

Other embodiments of the fastener and the upper metal holder will be described based on FIGS. 4 and 5.

A box-shaped upper metal fitting receptacle lO with an open top and forming an upper fitting part is embedded in the upper surface of the wall panel l on the connecting surface side.

A through hole 11 is provided in the end piece on the connecting surface side of the upper metal fitting receiver 10, and the through holes 11 of the joined wall panels l are made to coincide with each other. The shaft 12a of the fastener 12, which is a tool, is inserted into the fastener 12 (see FIG. 4).The fastener 12 is formed with a holding portion 12b which is bent into an O-shape. The fastener 12 is a shaft 12a
is passed through the through hole 11, and the clamping part 12b is rotated about the shaft 12a, so that the clamping part 12b clamps the end pieces of the upper metal fitting receiver 10 together (see FIG. 5). .

This upper metal fitting receiver 10. According to the fastener 12, the upper part of the wall panel l can be clamped as described above, and at the same time, by passing the shaft 12a through the through holes 11, it is possible to prevent the wall surfaces of the wall panels 1 from shifting. is also possible.

<Effects of the Invention> The wall panel joining structure according to the present invention includes a lower fitting part that regulates the lower connecting position of the wall panel, a lower metal fitting, and an upper fitting part that joins the upper parts of the wall panels.

Since it is comprised of a clamping tool, it is possible to join wall panels on-site without nailing. As a result, it becomes possible to join pre-finished wall panels on-site, and the workability of connecting and joining wall panels can be significantly improved.
