Description

[Detailed explanation of the invention] A. Purpose of the invention (industrial application field) This invention relates to the structure of the corner of a steel core frame that is incorporated into wall materials forming partitions, external walls, etc. of buildings.
This is a device that can be used to assemble steel core frames without using welding means.

(Prior Art) Wall materials having a steel core frame have conventionally been constructed as shown in FIGS. 4 to 6. That is, a vertical member 1 and a horizontal member 2 made of steel with a U-shaped cross section are butted at right angles and welded 3 on the inner parts to form a rectangular core frame 11. At the same time as bonding the panel 4, bend the aluminum edge material 5 bonded to the edge of the outer panel to sandwich the vertical members 1 and horizontal members 2, join the core frame 11 and the outer panel 4, and attach the outer panel 4. A wall material was constructed by gluing a heat insulating board 6 and then gluing an inner panel 7 to the vertical members 1, horizontal members 2, and the heat insulating board 6.

To make such wall materials, first, the vertical members 1 and horizontal members 2 are cut to the specified dimensions at the parent factory, and then transported unwelded together with the inner and outer panels and insulation materials to the on-site factory. A core frame was made by welding, and inner and outer panels and insulation materials were attached to this to form the wall material.

However, since toxic gas is generated when welding the core frame, it is difficult to carry out the work in small, poorly equipped on-site factories, so there has been a desire for a wall material manufacturing method that does not use welding means.

Therefore, the inventor of the present invention devised the wall material of the earlier application (Utility Application No. 62-60687, Utility Model Application No. 167508-1983) shown in FIGS. 7 to 9. This invention is characterized by the structure of the corner of the steel core frame, in which a slit 8 is formed on the surface of the vertical member 1 facing the horizontal member 2, and the slit 8 is inserted into the horizontal member 2. The protruding piece 9 is made to protrude, and the tongue piece 10 is cut and raised from the protruding piece 9.

To assemble the vertical member 1 and the horizontal member 2, as shown in Fig. 7, push the protrusion 9 into the slit 8 of the vertical member.
Due to its elasticity, the tongue piece 10 slides down to form the slit 8.
, and after passing, it rises to prevent the protrusion 9 from coming out of the slit 8.

After joining the four sides of the core frame 11 in this way,
The outer panel 4, heat insulating board 6, and inner panel 7 are glued and attached in the same manner as before. If only the slits 8 and the projections 9 are fitted together, the vertical members 1 and the horizontal members 2 will still be joined together with some wobbling, but the bonding of the inner and outer panels etc. will ensure that they are joined without any wobbling. In this embodiment, the slits 8 are formed on the vertical members and the projecting pieces 9 are formed on the horizontal members, but the vertical members and the horizontal members may be reversed to form slits, projecting pieces, etc.

(Problem to be solved by the invention) Normally, steel plates with a thickness of about 1 m/m are used for the vertical members 1 and the horizontal members 2, but if the corners of the core frame are constructed as in the previous invention, Since the rigidity of the tongue piece 10 is increased, a large force is required to slide the tongue piece 10 down and pass through the slit 8. Therefore, in order to allow the tongue piece 10 to pass through the slit easily and to facilitate the assembly of the corner of the core frame with the previously devised structure, the protrusion length of the protrusion piece 9 is increased, and the protrusion piece 9 is inserted deeply into the mating material. I had to let it in. That is, if the protruding piece 10 is bent sufficiently, it requires a large force to pass through the slit, which is inconvenient for work.If the tongue piece is bent to a small degree in order to make it easier to pass through the slit, the tongue piece will becomes easier to slip out of the slit.

Therefore, if the protruding piece 9 is made longer and the tongue piece is also made longer, even a slight bending will catch on the slit and the above-mentioned disadvantage will be eliminated. If it is large, it cannot operate smoothly. Therefore, it was desired to keep this protrusion length within 8m/m. However, if the length of the protruding piece 9 is so short, the tongue piece 10 cannot pass through the slit and be locked properly.

B. Structure of the device (means for solving the problem) This device solves the above problem by lowering the rigidity of the tongue so that the tongue can be easily bent. .

(Function) A U-shaped hole 12 is formed in the protruding piece 9, and the locking part 14 is connected to the vertical member or the horizontal member by the narrow parts 13, 13a along this, so the narrow part 13, which has low rigidity,
13a, even if the protruding length of the protruding piece 9 is shortened, the locking part 14 is elastically bent with a relatively small force to pass through the slit 8 of the mating material, and after passing through the slit, the tongue piece 10 rises and locks in the slit sufficiently securely.

(Embodiment) Figures 1 and 2 show a first embodiment of the present invention.
The figure is a perspective view of the vertical member and the horizontal member separated, Figure 2 is a vertical sectional view of the central part when assembled, and Figure 3 is a plan view of the tip of the horizontal member showing the second embodiment of the present invention. .

Hereinafter, the above embodiment will be described using the same reference numerals for parts equivalent to those of the conventional example and omitting the explanation.

The protruding length of the protruding piece 9 formed at the tip of the cross member 2 is made shorter than that of the previous design, and the protruding length is 8 m/m. This projecting piece 9 is provided with a U-shaped hole 12 that opens outward, and a narrow part 13 in the longitudinal direction is formed between the edge of the projecting piece 9 and the U-shaped hole 12 in a direction perpendicular to this. A narrow portion 13a is formed. Further, a similar narrow portion 13b and a locking portion 14 are formed by recessing the recessed portion 15 from the outer end of the protruding piece 9.

The locking portion 14 functions in the same manner as the previously devised tongue piece 10, and is first bent slightly. Since the locking portion 14 is supported by the narrow width portions 13, 13a, and 13b, each of these portions can be bent or twisted with a small force. When pushed into the slit 8 of the vertical member 1, the locking portion 14 easily slides down and passes through the slit 8, then rises and hooks on the edge of the slit.

In this way, the locking portion 14 is connected to the narrow portions 13, 13a,
Since it is supported by 13b, even if the projecting length of the projecting piece 9 is shortened, it can be easily slid down with a small force and passed through the slit.

In the above embodiment, the locking portion 14 is connected to the narrow portions 13, 13.
Since it is supported by a and 13b, the amount of deflection can be increased, but in the second embodiment shown in FIG. 3, the concave portion 15 is not formed, and therefore, the shape is such that there is no narrow portion 13b.

The locking portion 14 is formed to have relatively high rigidity, but is supported by the narrow width portions 13, 13a, and both portions 13,
By bending and twisting 13a, it easily passes through the slit 8, and then rises elastically and locks onto the edge of the slit.

With this structure as well, the protruding length of the protruding piece 9 can be made small.

C. Effect of the invention (1) Projection piece 9 formed at the end of the vertical member 1 or the horizontal member 2
The locking part 14 bent from the narrow part 13,1
3a, 13b or the narrow width portions 13, 13a, the force required to bend the locking portion 14 is reduced, and the amount of protrusion of the protruding piece 9 is reduced, allowing the current assembly machine to be used as is. You will be able to do this.

(2) Forming the U-shaped hole 12, the recess 15, etc., and bending the locking portion 14 can be done all at once by pressing, making the work easy.
