Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a joint bar mounting structure that forms a joint of a wall panel for interior and exterior of a building.

(Prior Art) Conventionally, as a method of attaching the joint bar to the joint gap between the wall panels, the joint bar is fixed to the base material fixed to the building body with screws or an adhesive, but the former method is used. And the screw head was exposed on the joint sticking surface, which was not desirable in appearance. In the case of the latter method, the joint bar had low attachment strength and was easily detached, and the adhesive deteriorated, and the service life was short.

(Problems to be solved by the invention) This invention solves the above-mentioned conventional problems. The joint part has an excellent appearance, the joint bar has a large mounting strength, and the joint bar can be easily attached and detached. It is intended to provide structure.

(Means for Solving the Problems) However, the joint rod mounting structure of the present invention has a short U-shaped section in which side plates are connected to both edges of the bottom plate and projecting pieces are provided outside the side plates. The fitting is inserted into the joint space between the side-by-side wall panels and attached to the base material, and the side wall is continuously provided on both edges of the top plate, and the locking piece 12 engaging with the projecting piece 22 is provided inside the side wall. A long joint bar having a U-shaped cross section locally provided at a position corresponding to the protruding piece is fitted to the mounting metal fitting with the engaging piece mounting position aligned with the mounting metal fitting position. It is a joint bar mounting structure that is formed by.

(Operation) In the joint rod mounting structure of the present invention, even if the joint rod is subjected to a force outwardly of the wall surface, the projecting piece of the mounting bracket engages with the locking piece of the joint rod and Preventing the departure to the outside,
The joint bar is securely prevented from coming off. Since the joint rod is held on the inner surface side by the mounting member, it is not necessary to use a screw penetrating the top plate portion, and an excellent joint portion appearance can be obtained.
Also, the joint bar can be fitted and fixed to the mounting bracket by one-touch because the mounting bracket can be elastically deformed just by pushing it into the joint gap, and when removing the joint bar for repairing the wall panel, etc. If you move the joint by a small distance in the longitudinal direction and shift the position where the joint bar locking piece is attached from the position of the mounting bracket, the locking piece and the protruding piece of the mounting bracket will not engage, and in this state the joint bar Can be easily removed from inside the joint gap by pulling outward. Also, by performing the reverse procedure of this removal, by pushing the joint bar into the joint gap with the locking piece attachment position of the joint bar displaced from the mounting metal fitting position, and then shifting the joint bar in the longitudinal direction, It is possible to attach joint bars.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS.

In FIG. 1, reference numeral 1 is a steel base material fixed to a building body (not shown) with anchor bolts or the like. Reference numeral 2 denotes a wall panel for exterior, which is a shallow box-shaped enamel panel having a backing material 3 attached thereto. Two adjacent wall panels 2 and 2
Is fixedly attached to the base material 1 with a joint gap 5 by tightening the clip 4 fixed to the bent piece portion 2a of the panel to the base material 1 with a tap pin screw. In the joint gap 5, a mounting member 6 is fastened and fixed to the base material 1 with a tatsupin screw 7, and a joint rod 8 is fitted into the mounting member 6 to form a joint. As shown in FIG. 2, the joint bar 8 has a U-shaped cross section in which side walls 11 and 11 are connected to both edges of the top plate 10, and is a long bar member having the same size as the length of the wall panel 2, for example. Made of metal material such as stainless steel, aluminum, etc. On the inside of the side wall 11 of the joint bar 8, locking pieces 12 whose edges are inclined toward the top plate 10 are locally provided at several locations by relatively long pitches (for example, 1 m) by cut-and-molding. There is. As shown in FIG. 3, the mounting bracket 6 has a U-shaped cross section in which side plates 21 and 21 are continuously provided on both edges of the bottom plate 20, and has a short length formed by bending a metal plate such as a stainless plate (for example, L = 20 mm) bent product. Each side plate 2
The upper end of 1 is provided with a protruding piece 22 formed by folding back outward, and the bottom plate 20 has a hole 2 for inserting a tatsupin screw in the center thereof.
3 is drilled.

At the time of joint construction, the above-mentioned mounting metal fitting 6 is at substantially the same pitch (for example, 1 m) as the pitch of the locking piece 12 of the joint bar 8,
Tighten the base material 1 with the Tatsupin screw 7, and fix the joint bar 8
May be pushed into the joint gap 5 in the direction of arrow X (see FIG. 1) with the position of the locking piece 12 aligned with the position of the mounting bracket 6. The fitting 6 is elastically deformed and the joint rod 8 is pushed to a predetermined position, and the protruding piece 22 presses the inner surface of the side wall 11 of the joint rod 8 to hold the joint rod 8. Further, even if the joint bar 8 receives a large force outward (in the direction of the arrow Y) and moves a small amount due to an abnormally large wind pressure, the protruding piece 22 of the mounting bracket 6 engages with the locking piece 12. The joint rod 8 is prevented from coming off from the outside. When the joint rod 8 needs to be removed, if the joint rod 8 is grasped at its end and pulled in the longitudinal direction and the locking piece 12 is displaced from the position of the mounting bracket 6, the joint rod 8 can be freely moved outward ( Can be taken out in the direction of arrow Y).

The present invention is not limited to the above-described embodiment. For example, as shown in FIG. 4, the joint bar 8 and the locking piece 12 are provided with several short locking pieces 12 arranged side by side (where the gap S is The length may be smaller than the length of the mounting bracket 6), and it may be locked by welding a round bar as shown in FIG. 5 or by fixing a bent plate as shown in FIG. Piece 12
May be formed. Similarly, the protruding piece 22 of the mounting bracket 6
Alternatively, for example, as shown in FIG. 7, it may be formed by welding a round bar material. Further, as shown in FIG. 8, a middle piece is bent outward to form a bent piece-like protruding piece 22. When the joint bar 8 is fitted, the inclined piece portion 22a at the tip is constantly in pressure contact with the locking piece 12 of the joint bar 8, so that the joint bar 8 is further preferably attached without deviation or rattling to the outside. Can be obtained. Also, the mounting of the mounting bracket 6 to the base material 1 is
Alternatively, a screw other than the tap pin screw 7 may be used.

(Effect of the Invention) As described above, according to the present invention, it is possible to obtain a useful joint rod mounting structure in which the joint portion has an excellent appearance, the joint rod has a large mounting strength, and the joint rod can be easily attached and detached.
