Description

[Detailed Description of the Invention] This invention relates to a locking structure for attaching a plate such as a heat insulating board, for example a polystyrene foam board, to a section steel of a building frame.

The purpose is to propose a plate locking structure that can accurately and easily lock a plate, requires fewer members for locking, and can reduce costs.

Conventionally, when attaching a plate such as a heat insulating plate to a shaped steel, a joiner for the plate was fixed to a predetermined position on the shaped steel using screws, etc., the plate was attached to this joiner, and the plates were attached to each other at the same time. It was connected and mounted.

This method requires complicated and time-consuming fixing of the joiner;
It was difficult to mount the plates accurately because it was difficult to adjust the position after installing the joiner.

In addition, a method has been devised for locking the joiner to the shape steel by using a plurality of hooks fixed to the joiner for locking the long joiner to the shape steel. Since the hook cannot be moved in the longitudinal direction of the joiner, there is a drawback that it cannot be applied to buildings where the span spacing of the section steel is uneven.

. This invention solves the above drawbacks and also
The purpose of this is to reduce the number of members required for locking and provide an inexpensive device.

：Hereinafter, it will be explained with reference to the illustrated embodiment.

FIG. 1 shows a joiner used in the plate mounting structure of this invention.

This joiner consists of a female part A and a female part B each having a T-shaped cross section, each having a strip cover piece 1 that covers the joint of the plate and a strip leg piece 2 that intersects the strip leg piece 2 perpendicularly to the strip cover piece 1. is long (several lengths), and female part B is short (several Ca1~20CF71)
It becomes.

The strip leg piece 2 of the female part B consists of three parallel pieces, with a groove strip 3 between them.
is provided, and by inserting the strip leg piece 2 of the female part A, the male and
The plate can be held between the female strip pieces.

In addition, there are a plurality of protrusions 4 that engage with each other on the side surface of the conical part A strip leg piece 2 and the inner surface of the female part B groove 3, and engage with each other to firmly clamp the plate. The structure is such that it can be done.

A locking portion 5 for locking the female portion B to the section steel is provided on the surface of the strip covering piece 1 of the short female portion B.

This locking part 5 is made by bending an elongated rectangular spring steel plate,
・Fixed to the surface of the strip covering piece 1 at one end, bent to have a V-shaped cross section in order along the length direction of the strip covering piece 1, and the supporting piece 6 that stands up is attached to the surface of the strip covering piece 1. It consists of a clamping piece 7 and a guide piece 8 that is bent and stands up at an acute angle with respect to the surface of the strip covering piece 1.

The state in which the plate body is attached to the lip channel steel using the joiner consisting of the male and female parts A and B is shown in Figs. 2, 3, and 4.

When installing this, attach the female part B to the lip channel steel 9.
With the surface aligned with the side wall surface of the lip channel steel, the tip of the guide piece 8 is placed on the edge of the lip 10, and the guide piece 8 and the clamping piece 7 are pushed into the groove of the lip channel steel 9. , lip 10
is housed in a support piece 6 having a V-shaped cross section, and the female part B is locked to a section steel 9.

The female portions B, which are engaged with a plurality of lip channel steels 9 arranged in parallel, can be moved freely in the longitudinal direction of the section steel, so the female portions B can be moved perpendicularly to the section steel 9. The strip legs 2 of the elongated female part A are pushed and fitted across the grooves 3 of the plurality of female parts A, and the male and female parts A,
The edge of the plate 11 is held between the strip cover pieces 1.1 of B, and the plate 11 is mounted on the section steel 9.

When the entire structure is mounted, the mounted plate 11 no longer moves and is stably fixed.

The locking part 5 attached to the female part B of this joiner is conversely attached to the short female part A, and first the female part A is locked to the section steel, and then this is attached to the long female part B. It is also possible to attach the plate by inserting it into the plate and engaging it.

The clamping part 7 of the locking part 5 is shaped like #l between the surface of the strip covering piece 1.
It is preferable if the side wall of I9 is pressed and held by the spring elasticity of the spring steel plate, since the locking stability to the shaped steel improves.

It is also convenient for locking onto channel steel or angle steel without lips.

However, in the case of a lip shaped steel, the lip fits inside the support piece 6 and does not come off, so it is not necessarily necessary to press and hold the lip between the clamping piece 7 and the strip covering piece 1.

The shape of the locking portion 5 is not limited to that of the embodiment described above.

There are various embodiments, examples of which will be explained with reference to the drawings of the following embodiments.
