Abstract

PURPOSE: To support a heat insulating material while a support piece is not easily deformed so as to be surely fitted to a base material. CONSTITUTION: A locking piece 2 is horizontally connected to the upper end of a hanging piece 1 and a support piece 3 is connected horizontally in the opposite direction to the locking piece 2 to the lower end of the hanging piece. Plural locking clicks 4 having different directions, which are buried in a building base material, are projected downward on the locking piece 2. The hanging piece 1 and the support piece 3 are provided with projections 6 which are continuous between both pieces and bulged toward the surfaces of both pieces. The forward end piece of the support piece 3 that is positioned in front of the projection 6 is inclined in such a manner as to be gradually raised as it goes toward the free end.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting member for a heat insulating material which is arranged under a building floor for the purpose of heat insulating effect.

[0002]

2. Description of the Related Art For example, as disclosed in Japanese Utility Model Publication No. 61-39763, a suspending piece is connected horizontally to an upper end of a hanging piece, and a lower end is horizontally connected to a supporting piece in a direction opposite to the engaging piece. There is a structure in which a locking claw to be embedded in a building base material is provided on the locking piece so as to project downward, and a curved portion bulging forward is provided at an intermediate portion of the hanging piece.

In this conventional example, a locking claw is driven into the upper surface of a base material such as a joist, a board-shaped heat insulating material is supported by a support piece, and a processing error in the size of the heat insulating material is absorbed by elastic deformation of the curved portion. It is intended to maintain the support state of the heat insulating material by the support piece.

[0004]

In the above-mentioned conventional example, structurally, the heat insulating material is supported by the support piece, but in order to make the elasticity of the curved portion function, the metal plate should be used as much as possible. It is necessary to make it thin (though the thinner the metal plate that is the material is, the better the metal fittings of this kind are because of the interposition of the locking piece between the floor material and the base material). If this is done, the rigidity of the support piece will decrease, and the support piece may be so-called sagging and the heat insulating material may fall from the support piece (Note that in order to prevent this drop, the support piece has a claw protruding Although it is described in Japanese Utility Model Publication No. 57-29755, since the structure does not prevent the sagging of the support piece, the heat insulating material may drop from the support piece.

Therefore, in the above-mentioned conventional example, when a thin metal plate is used as a material, the end portion of the heat insulating material is pressure-welded to the curved portion, and the frictional resistance resulting from the pressure welding and the slight rigidity provided by the support piece are provided. Since it is necessary to maintain the support state of the heat insulating material by using, the work of constructing the heat insulating material becomes complicated.

Further, in the conventional example, since the locking claw provided on the locking piece is unidirectional, the locking claw cannot be easily driven and embedded due to the presence of the hard portion of the wood material of the base material. is there.

The present invention provides a fixture for a heat insulating material, which is made of an elastic thin metal plate, which is free from the drawbacks of the conventional example and has good usability, and which surely maintains the support state of the heat insulating material. It was created for that purpose.

[Means for Solving the Problem] A hanging piece is horizontally provided on an upper end of a hanging piece, and a support piece is continuously provided on a lower end thereof in a direction opposite to the opposite direction, and a supporting piece is continuously provided on the hanging piece as a building base material. A plurality of locking claws to be embedded, which are different in direction from each other, are provided so as to project downward, and the hanging piece and the supporting piece are continuous between the both pieces,
In addition, a protrusion is provided that bulges in the surface direction of both pieces, and the tip end piece of the support piece, which is located in front of this protrusion, is formed in an inclined shape that gradually rises in the free end direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The drawings show an embodiment of a heat insulating material fitting made of an elastic metal thin plate according to the present invention. FIG. 1 is a front view, FIG. 2 is a plan view, FIG. 3 is a side view, and FIG. 4 is a bottom view. 5 is a vertical sectional view, FIG. 6 is a sectional view showing a state of use, FIG. 7 is a front view of the second embodiment, FIG. 8 is a plan view of the same, and FIG. 9 is a side view of the same.

In the figure, reference numerals 1 and 1 denote hanging pieces which are arranged relative to each other via a locking piece 2 which is continuously provided at the upper end, and the lower ends of the hanging pieces 1 and 1 are horizontally arranged in the opposite direction to the locking piece 2. The support pieces 3, 3 are connected in series to form the mounting bracket A of the first embodiment.

The mounting bracket A is a thin elastic metal plate (0.4 m
(thickness of m to 0.6 mm) is obtained by press working,
A plurality of locking claws 4, ..., Which are formed in a circular shape by stamping and have different directions from each other, are provided at the two positions of the locking piece 2 of the mounting bracket A so as to project downward.

The locking claws 4, ... Have a substantially triangular shape so that they can be easily embedded in the base material 5 of the building, and as described above, the base material (wood) 5 is made different in direction. Corresponding to the hard and soft wood grain, either one can be surely embedded in the base material 5.

Also, the hanging piece 1 and the supporting piece 3 of the mounting bracket A.
Is provided with a ridge 6 which is continuous between both pieces 1 and 3 and bulges in the surface direction of both pieces 1 and 3, and the presence of the ridge 6 imparts rigidity to the hanging piece 1 and the support piece 3. However, both pieces 1 and 3 are not easily deformed.

The tip piece 3a located in front of the ridge 6 of the support piece 3 is formed into an inclined shape which gradually rises in the direction of its free end, and the tip piece 3a is made of a heat insulating material (a styrofoam material on a board is usually used. 7), or due to its elasticity, it is pressed against the heat insulating material 7 (holding the heat insulating material 7 together with the floor material 8) so that the heat insulating material 7 does not come off from the support piece 3.

The hanging pieces 1 and 1 form an engaging gap 9 with which the base material 5 is engaged.

Then, the base material 5 (generally joist) 5 is engaged with the base material 5 in the engagement gap 9 and the locking claw 4 is driven in to mount the mounting bracket A, and the support piece 3 is thermally insulated. Material 7
One end of the heat insulating material 7 is supported (the other end of the heat insulating material 7 is also used).

The second embodiment shown in FIGS. 7 to 9 is different from the first embodiment in that the first embodiment is provided with a pair of support pieces 3 and 3, but one support piece 3 is provided. However, the remaining points are the same as in the first embodiment.

[0018]

Since the present invention is constructed as described above, even if an external force is applied to the support piece from above, the support piece is not easily deformed by the presence of the ridge, and the tip end piece of the support piece is It can be pierced into the heat insulating material, or can be elastically pressure-contacted to prevent the heat insulating material from falling, and the presence of the locking claws in different directions makes it possible to smoothly perform the attachment work to the base material.
Generally, it is suitable for use in a mounting tool made of an elastic thin metal plate.
