Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an attachment structure for attaching an auxiliary frame member to a main holding frame.

[Conventional technology]

Conventionally, wall structures have been constructed as shown in FIG.

In the figure, 4 is a main holding frame on which a wall structure is formed, and has locking pieces 2, 2 extending parallel to the bottom wall 1 at tips a, a, and a bottom wall extending from the tips of these locking pieces 2, 2. It is formed in a U-shaped cross section with inwardly bent pieces 3, 3 bent in one direction.

The wall structure W is usually formed of a lath 20 attached to the surface side of the main holding frames 4 arranged in parallel, and a heat insulating layer 21 formed on the surface of the lath 20 by spraying.

However, in order to meet the desire to prevent the skin of the heat insulating layer 21 from being visually observed, a decorative board 22 is attached to the surface of the heat insulating layer 21.

[Problem that the invention attempts to solve]

However, in the wall structure with the above configuration, the decorative board 22 is directly attached to the surface of the heat insulating layer 21, but since the surface b of the heat insulating layer 21 is an uneven surface, there is a problem that it is difficult to attach the decorative board 22. .

Another problem was that it was not possible to form a certain gap between the decorative board 22 and the surface b to enhance the heat insulation effect due to the air layer. Therefore, it is conceivable to provide an auxiliary frame material to which the board is attached, but fixing this auxiliary frame material to the main holding frame requires fixing with screws or the like, which makes the work complicated.

The present invention was devised in view of the above-mentioned problems, and its purpose is to easily attach an auxiliary frame material for pasting decorative boards, etc. to the main holding frame.

[Means for solving problems]

In order to achieve the above object, the present invention provides a connecting member 8 made of a flat plate piece, a punched piece 8a to be inserted into the opening 4a of the main holding frame 4, and a punched piece 8a inserted into both edges 8b, 8b. Locking protrusions 8c, 8c that lock at the tip of the bent piece 3 are provided, and the connecting member 8
A bent piece 8d is provided to deform the tip end side toward the opening 4a and fit into the bent piece 8d, and projecting pieces 8e, 8e are provided on both sides of this bent piece 8d, and each locking piece 2,
2, the connecting member 8 is attached to the main holding frame 4 via the punched piece 8a and the bent piece 8d, and the cross-sectional shape of the auxiliary frame member 5 is made into a substantially U-shape. It has a shape that has an inwardly bent piece 11 extending in a direction parallel to the bottom wall 5b at its tip, and is fitted into the connecting member 8 on the opening side of the auxiliary frame member 5, and the tip of the inwardly bent piece 11 is engaged with both side edges 9a, 9a. It is characterized by providing protrusions having locking recesses 9c, 9c.

[Effect]

The auxiliary frame member is fixed to the main holding frame via the connecting member.

〔Example〕

Hereinafter, the present invention will be explained with reference to FIGS. 1 and 2 showing one embodiment thereof.

It should be noted that, since this example illustrates the attachment structure of the auxiliary frame member to the main holding frame, the same members and parts as those of the conventional example are given the same reference numerals, and detailed explanation thereof will be omitted.

In FIG. 1, the lath 20 of the wall structure W is attached to one surface of the holding member 4, and a heat insulating layer 21 is formed on the surface of the lath 20 by spraying. An auxiliary frame member 5 is disposed perpendicularly on one surface of the holding member 4, and a decorative board 22 is attached to the outside of the bottom wall 5b of the auxiliary frame member 5.

By separating the decorative board 22 and the heat insulating layer 21 and maintaining a constant gap 1,
It forms an air layer that enhances the insulation effect. The auxiliary frame member 5 is attached to the main holding frame 4 by a connecting member 8.

The auxiliary frame material 5 has the same cross-sectional shape as the main holding frame 4, and has an opening 5a, locking pieces 10, 10 extending parallel to the bottom wall 5b, and tips of the locking pieces 10, 10 extending parallel to the bottom wall 5b. Bent pieces 11, 11 bent in the direction of the wall 5b
It is equipped with

The connecting member 8 is made of a flat plate and includes a punched piece 8a, a bent piece 8d, and a back piece 9.

The punched piece 8a is inserted into the opening 4a of the main holding frame 4, and has locking protrusions 8c on both edges 8b, 8b that lock onto the tips of the inwardly bent pieces 3 of the main holding frame 4.

Note that 8m is an opening formed by the punched piece 8a.

The bent piece 8d deforms the distal end side of the connecting member 8 in the direction of the opening 4a so that it can be fitted into the opening 4a, and is also formed to extend in a direction perpendicular to the main holding frame 4. Further, the bent piece 8d is provided with overhanging pieces 8e on both sides, and each overhanging piece 8e is provided with a pressure contact piece 8f that presses against the back side of the locking pieces 2, 2 of the main holding frame 4. The connecting member 8 is attached to the main holding frame 4 by the bent piece 8d and the punched piece 8a.

The projecting pieces 9 are provided on both sides of the connecting member 8 and protrude from both sides of the main holding frame 4, but may be provided only on the left side as illustrated in FIG.

This projecting piece 9 consists of two tongue pieces 9l and 9m,
It is fitted into the opening 5a side of the auxiliary frame material 5, and the both side lines 9a
has a locking recess 9c in which the tip of the inwardly bent piece 11 locks.
has been established. This locking recess 9c is
When the auxiliary frame member 5 is engaged with the tip of the main holding frame 4 via the projecting piece 9, the auxiliary frame member 5 is attached to the main holding frame 4. In addition, the tongue pieces 9l, 9
Locking recesses 9c, 9c are also provided on the inner edges 9x, 9x of m.

In the above configuration, the punched piece 8a and the bent piece 8
By fitting d into the main holding frame 1, the connecting member 8 can be attached, and then by fitting the auxiliary frame member 5 to the protruding piece 9, the auxiliary frame member is fixed. Therefore, since the auxiliary frame member 5 is attached via the connecting member 8, the attachment work is significantly simplified.

In particular, when moving the connecting member 8 in the longitudinal direction of the main holding frame 4, by inserting your finger into the opening 8m and pressing the punched piece 8a, the movement becomes extremely easy and positioning can be performed quickly. can. The present invention can also be applied to the case where the auxiliary frame material is attached to the main holding frame while maintaining parallelism.

[Effect of idea]

As described above, the present invention is characterized in that a connecting member for attaching the auxiliary frame member to the main holding frame is provided. Therefore, the auxiliary frame member can be easily attached without using screws or the like, and the auxiliary frame member can be used to perform work such as attaching a board, for example.

Further, the connecting member can be slid by pressing the punched piece, and the auxiliary frame member can be easily positioned.
