Abstract

PURPOSE: To facilitate mounting operation by forming a joint section by fixing a joint receiving member with a section to be rotated and an engaging section onto a backing material while holding the end section of an adjacent panel and engaging the spring plate of a joint cover member with the engaging section. CONSTITUTION: The bent piece 4 of an adjacent panel 1 is abutted against a backing material 13 while being faced oppositely, a joint receiving member 5 is applied from a lower section, and the bent piece 4 is held and fixed by a screw 14. When the shaft-like section to be rotated 7 of the fixed joint receiving member 5 is covered with the bearing like rotary section 10 of a joint cover member 8 and turned, the free end section of a spring plate 12 is engaged with an engaging section 6 while being elastically deformed. The shielding piece 9 of the joint cover member 8 is fixed in a shape that the joint receiving member 5 is covered from the lower section of the joint receiving member 5, and a fine joint section 15 is formed of both side pieces 3 of the panels 1 and the shielding piece 9. Accordingly, the joint member can be mounted and dismantled simply.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint structure in a building panel such as a ceiling or inner and outer walls.

[0002]

2. Description of the Related Art Conventionally, a joint portion formed between adjacent panels has joint joint covers formed on both upstanding pieces 17 and 17 of a joint receiving member 16 which is previously fixed to the joint bottom surface as shown in FIG. Both the standing pieces 19, 19 of the member 18 were elastically fitted together.

However, since the rising pieces of these joint members are short, the spring property is small, and since the joint cover member is long, it is difficult to fit them, and it is easy to hit them with a hammer and hit them with a hammer. It wasn't work. This fitting force has a drawback that a considerable difference occurs due to the aluminum extrusion precision of the joint member, the difference between the alumite treatment and the coating treatment, and the fitting is tight or loose. Also, it is extremely difficult to remove the joint cover member once fitted, so most of the time, when you want to replace the panel, you have to break the joint cover member and remove it.
It was not possible to reuse the joint cover member.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to eliminate such drawbacks. That is, the fitting force varies even if there is a difference in the aluminum extrusion accuracy of the joint member or the alumite treatment and the coating treatment. The purpose is to create a joint structure that does not have any joints and that allows secure and stable fitting. A second object of the present invention is to easily attach and detach the joint member,
Moreover, the joint structure enables reuse of the joint cover member even when the panel is replaced.

[0005]

SUMMARY OF THE INVENTION To solve the above problems, the present invention provides a joint structure for a building panel, which is a substrate with a joint receiving member having a pivoted portion and a locking portion sandwiching an end portion of an adjacent panel. A joint is formed between side pieces that are fixed to each other and opposed to each other, and one end or one end of one or more elastically deformable spring plates is held by a joint cover member having a shielding piece and a rotating portion. The free end of the spring plate when the turning piece of the joint cover member is rotatably engaged with the turning portion of the receiving member to allow the shield piece to swing in the joint portion and the shield piece is in the shield position. The portion is elastically deformed and is engaged with the engaging portion of the joint receiving member.

In the present invention, the joint receiving member may have both upstanding pieces, and a rotated portion and a locking portion may be provided on the joint receiving member. The rotating portion may be a bearing having a semicircular cross section, and one end of the spring plate may be held outside the bearing of the rotating portion. It may have a rotating shaft shape.
The number of spring plates is adjusted according to the required fitting force.

[0007]

According to the present invention, when the joint portion is shielded by the above construction, the free end portion of the spring plate is elastically deformed as shown by the chain line in FIG. Is fixed while being covered on the outside of the receiving member. Further, when opening the joint portion, if the end portion of the shield piece is pressed and rocked to be positioned vertically as shown by the solid line in FIG. 1, the spring plate is unlocked, so the joint member is easily removed. Can and can be reused.

Embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to these embodiments. 1 is a cross-sectional view showing an embodiment of the present invention, and FIG. 2 is a perspective view of the same embodiment.

In the embodiment shown in FIGS. 1 and 2, a panel 1 formed by bending an aluminum blank material includes a top piece 2, side pieces 3,
The outward bent piece 4 has a box shape, and the joint receiving member 5 made of an aluminum extruded material has two standing pieces and a fixing piece in a U shape, and one end of the fixing piece is extended from the standing piece. There is. A recessed groove-shaped engaging portion 6 is provided inside one of the upright pieces, and a rotated portion 7 having a circular cross section and a rotation shaft shape is provided at the other end of the upright piece.

A joint cover member 8 made of an extruded aluminum material.
Is a flat plate-shaped shield piece 9 and the rotated portion 7 on the back side of the shield piece 9.
A rotating part 10 in the form of a bearing having a semicircular cross-section that covers the rotating part 10 and is rotatable, and a protrusion 11 provided on the outer side of the rotating part 10.
Grooves are vertically provided in the ridge 11, a plurality of spring plates 12 are arranged at equal intervals, and one end thereof is inserted and fixed. The spring plate 12 has such a length that the free end portion of the spring plate 12 can be elastically deformed and locked by the locking portion 6 when the shielding piece 9 is covered with the joint receiving member 5, as shown by the chain line in FIG.

In order to form the joint in this embodiment, the folding pieces 4 and 4 of the adjacent panels 1 and 1 are made to face each other and are brought into contact with the base material 13, and the joint receiving member 5 is applied from below to bend them. Piece 4
While pinching, fix with screws 14. Further, the joint cover is attached to the rotary shaft-shaped rotated portion 7 of the fixed joint receiving member 5.
When the bearing 8 of the member 8 is covered and rotated counterclockwise, the free end of the spring plate 12 is elastically deformed and the locking portion 6 is released.
Lock on. In this state, the shielding piece 9 is fixed so as to cover the joint receiving member 5 from below as shown by the chain line in FIG. 1, and the screws and the like are shielded when viewed from below, so that both side pieces 3 and 3 and the shielding piece 9 are covered. Thus, a clean joint portion 15 can be formed.

Here, the locking force of the joint cover member 8 is determined only by the spring plate 12 regardless of the aluminum extrusion precision of the joint receiving member 5 and the alumite / painting process.
To change the locking force, it is only necessary to increase or decrease the number of spring plates 12.

When opening the joint for replacing the panel 1 or the like, the shield piece 9 of the joint cover member 8 which is locked is shown in FIG.
When the left end portion is pressed by the chain line, the free end portion of the spring plate 12 is disengaged from the engagement portion 6 and rotated together with the shield piece 9 in the clockwise direction to form the solid line in FIG. In this state, the screw 14 is removed and the panel 1 is replaced. The joint cover member 8 can be reused.

[0014]

EFFECTS OF THE INVENTION According to the present invention, the fitting force does not vary even if there is a difference in the aluminum extrusion precision of the joint member, the alumite treatment and the coating treatment, and a reliable and stable fitting can be obtained in any case. And a joint structure in which the fitting force can be adjusted. Further, the joint member can be easily attached and detached, and the joint cover member can be reused even when the panel is replaced.
