Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a light metal panel, and its purpose is to ensure that the joints of the unit members are firmly connected to each other and that there is no step at the joints. The purpose is to provide light metal panels whose combined structure is robust.

(Background of the Invention) Conventionally, it is impossible to weld a light metal, especially an aluminum material. Therefore, when constructing a large structure, as shown in FIGS. Plate material (a)
(A) is connected via a folded-back seam portion (b).

However, in such a structure, the connection state of the joint portion (b) is weak, and particularly in the case of FIG. 5 (A), the joint portion (b) is particularly weak.
A step (c) was generated on the surface.

Moreover, since the unit member is the plate material (a), the entire structure is fragile.

(Prior Art) There is a technique disclosed in Japanese Patent Publication No. 39-23875 as a panel in which no step is formed at the joint.

In this disclosed technique, as shown in FIG. 6, a required number of pipes (d) (d) having a quadrangular cross section are arranged side by side.
(D) ... penetrates in a skewered shape from the recesses (e) and (e) provided in the pipes (d) and (d) with a tightening rod (f).
A nut (g) is attached to both ends (l) and (l) of the tightening rod (f).
(G) is screwed and the nuts (g) and (g) are tightened to integrally connect the pipes (d), (d) ...

In addition, there is a technique disclosed in Japanese Utility Model Laid-Open No. 53-68538.

In this disclosed technique, as shown in FIG. 7, the gate constituent members (h) (h) are arranged in parallel and the fitting grooves (not shown) of the adjacent gate constituent members (h) (h). No.) and a fitting ridge (not shown) are fitted to each other, and connecting bolts (i) whose both ends are screw parts (not shown) are provided on these gate constituent members (h) (h). It is fitted through the through hole (k), the nuts (j) and (j) are fitted to the threaded portion, and the gate constituent members (h), (h) ... Are connected in series.

(Problems to be solved by the invention) However, in the technology disclosed in Japanese Patent Publication No. Sho 39-23875, both ends of the tightening rod are penetrated in a juxtaposed manner in a pipe shape. Since the pipes are integrally connected by screwing nuts to the portions, it is impossible to firmly connect these pipes.

The reason is that, for example, when an impact from the outside is applied to the panel made of these pipes, this panel bends and restores to its original state (flat plate shape), but these pipes have only the tightening force of the nut. That is, the pipes themselves are not fixed to the tightening rods, and if the bending and restoring of this panel is repeated, the nuts fitted in the tightening rods will loosen and gaps will be formed in the pipe surfaces. This is because the pipe may eventually come off the tightening rod.

Further, even in the technology disclosed in Japanese Utility Model Publication No. Sho 53-68538, similarly to the technology disclosed in Japanese Patent Publication No. Sho 39-23875, connecting bolts are provided in through holes of gate constituent members arranged in parallel. It is impossible to firmly connect the gate constituent members because they are fitted and a nut is fitted to the threaded portion of the connecting bolt to connect the gate constituent members in series.

The reason is that, for example, when an external impact or the like is applied to the panel composed of these gate constituent members, this panel bends and restores to its original state (flat plate shape). It is connected only by tightening force, that is, each gate constituent member itself is not fixed to the connecting bolt, and when bending and restoring of this panel is repeated, the nut fitted to the connecting bolt loosens, and these gate constituent members This is because a gap may be formed between them, and as a result, the gate constituent member may come off from the connecting bolt.

In light of the above circumstances, it is desirable in the industry to create a light metal panel in which the joints between unit members are solidly connected, there is no step at the joints, and the overall structure combining unit members is also robust. It was rare.

(Means for Solving the Problem) In this invention, a long rectangular light metal extruded material and a threaded rod having a screw thread engraved all around are formed. Surface contact between the long sides of each light metal extruded material, a series of threaded rods in a threaded state in a direction orthogonal to the lengthwise direction of a plurality of light metal extruded materials,
The above problem is solved by providing a light metal panel characterized in that a plurality of light metal extruded materials are integrally connected by biting a screw rod into the built-up portion of the joint portion.
