Description

[Detailed Description of the Invention] This invention relates to an assembly structure for a panel connection portion in which battens are attached to both sides of the connection portion of the panels, and these are tightly connected using bolts and nuts.

The purpose of this is to improve the ease of assembling the panel connections where the battens are fastened together with bolts and nuts, and to prevent damage to the battens caused by fastening the battens with bolts and nuts, especially rust caused by damage to the paint. This is a proposal for the structure of the connecting part.

' Conventionally, an assembly structure has been adopted in which batten boards are attached to both sides of the panel connecting portion, and the two batten boards are fastened together with bolts and nuts to clamp and fix the panels.

Figures 1 and 2 are examples of this conventional technique. To explain the figures, in Figure 1, 1.1' is a pair of panels to be connected, and 2, 2' are panels attached to the edges. It is a panel frame material.

A batten 3, 3' is attached to both sides of the connecting portion formed by the facing panel frame members 2, 2'.

The batten 3 on the indoor side (upper part in Figure 1) is formed by bending a single strip steel plate into a T-shaped cross section as shown in the figure, and the central connecting piece 4 inserted into the connecting part has a bent end. However, a screw hole 5 is provided.

The outdoor side batten 3' is made by folding both side edges of a single strip steel plate, and has a bolt through hole 6 in the center.

Then, insert the countersunk bolt 7 through the bolt through hole 6, screw it into the screw hole 5 of the connecting piece 4, and tightly connect the two battens 3, 3'.
Panel frame members 2 and 2' are sandwiched between them.

FIG. 2 also shows a conventional connection structure, in which a pair of panels 1,
1', battens 3, 3' are attached to both sides of the joint formed by the panel frame members 2, 2'.

A square hole 8 is bored in the indoor side panel 3, into which a square root round head cap nut 9 is fitted and inserted.

A bolt through hole 6 is provided in the outdoor eye plate 3', and a countersunk bolt 7 inserted through this hole is screwed into a square-root round-head bag nut 9 to tightly connect the two eye plates 3, 3'. , panel frame members 2, 2' are sandwiched between them.

As seen in the example above, the conventional connection structure uses countersunk bolts to fasten the battens, but the countersunk head of the countersunk bolt causes the paint around the bolt holes in the batten to peel off. Moreover, it rusts during use and spoils its appearance.

In addition, the nuts that are screwed into the bolts cannot be fixed to the batten, and are easily removed from the holes in the batten during assembly, resulting in low assembly workability using bolts.

This invention was made with attention paid to the above-mentioned problems.

The present invention will be explained below with reference to illustrated embodiments.

In FIGS. 3 and 4, a pair of panels 1 to be connected,
1', battens 3, 3' are attached to both sides of the joint formed by the panel frame members 2, 2'.

A square hole 8 for a nut is provided in the center of the indoor eye board 3 (upper side in Figure 3), and the square root of the square root leading cap nut 9 is fitted and inserted into this square hole. .

Further, a neoprene washer 10 is interposed between the nut 9 and the batten 3.

There is a U groove 11 perpendicular to the nut axis on the outer peripheral surface of the square root of the nut 9. A snap pin 12 is inserted into this groove 11, and between the nut head and this snap pin 12, the nut 9 is inserted into the square hole 8. It is latched and fixed.

On the other hand, the outdoor side batten 3' has a bolt through hole 6, and a leading bolt 13 is inserted between the batten 3' and the batten 3' through a polyethylene washer 10', and its tip is screwed into a nut 9. Then, tighten the two battens 3, 3', and attach the panel frame material 2,
2' is clamped and fixed.

In this embodiment, when assembling the connecting part by tightening the battens attached to both sides of the panel connecting part with bolts and nuts, the nuts 9 fit into the square holes 8 of the batten 3, and the bolts 13
It does not rotate when the bolt is rotated, and it is fixed in the square hole 8 by the snap pin 12 so that it does not fall out, so the screwing work of bolts and nuts is extremely easy.

Also, since nut 9 and bolt 13 are the first ones,
The surfaces in contact with the battens 3, 3' are flat, and the paint on the battens will not be peeled off by the head of the nut or bolt, unlike countersunk bolts.

It should be noted that if a soft washer such as the polyethylene washer 10' is inserted as in the embodiment, it will be even more effective.

Figures 5a and 5l) and Figure 6 are enlarged views showing the structure of the square root of the nut 9 of the above embodiment and the snap pin 12 attached thereto.

Figures 7a and l) and Figure 8 show another embodiment, in which a top cap nut 14 is used, and the root has two parallel U grooves 11 perpendicular to the nut axis direction. A U-shaped presser piece 15 with a narrow opening end is fitted into the groove, and the nut 14 is fixed in the batten nut hole to prevent it from falling out.

In addition, when the holding piece 15 is attached to the nut 14, it protrudes laterally with respect to the nut axis and comes into contact with the end surface of the panel frame members 2, 2' of the connecting portion, thereby preventing rotation when screwing with the bolt. be able to.

In addition, in this invention, in order to prevent the nut from falling when removed from the batten and to fix it, or to prevent the nut from turning when tightening the bolt, the snap pin 12 or U-shaped nut is used in the above embodiment. Although the presser piece 15 is used, it is not limited to this.

For example, a rod-shaped presser piece may be fitted or screwed into a hole provided in the nut root so that it extends laterally.

This idea is as described above, and the nut attached to the batten on one side is fixed by the holding piece and does not fall out, and is also prevented from turning around, so it cannot penetrate through the batten on the other side. This improves work efficiency when screwing together the bolts inserted, and the efficiency of assembling the panel connection portion can be increased.

Moreover, since the first one is used for the poles 1 to 1 and the nuts, the paint on the battens does not peel off and damage unlike conventional countersunk nuts, and rust can be prevented.

Note that if a soft washer made of polyethylene or the like is interposed between the bolt or nut and the batten, damage to the batten can be more completely prevented.
