Abstract

PURPOSE:To prevent a floor plate from warping due to the weight of a furniture, etc., by forming a base making surface contact with a base floor face, a receiver making surface contact with the under face of the floor plate, and the intermediate support placed in connection between the base and the receiver, as a unit. CONSTITUTION:A receiving part 6a provided with a cutting blade-shaped front, an intermediate support 6c, and a base 6b are connected as a unit so as to form a nearly Z-shaped steel support metal fitting 6. Next, a shock-absorbing member 2 made of foamed rubber is laid down on the base floor face 1 and floor end joists 4 are formed at the edges of the shock-absorbing member 2, and the receiving part 6a of the support metal fitting 6 is inserted from the underface side of the shock absorbing member 2 at the position where the front part of a furniture 7 is placed. Next, the base 6b of the support metal fitting 6 is rotated and the intermediate support 6c is inserted in the shock absorbing member 2. And further, floor plates 3 are laid down on the upper face of the shock-absorbing member 2 to form a flooring bed 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a distortion preventing member for suppressing deformation of a flooring floor on which a heavy object such as furniture is placed.

[0002]

2. Description of the Related Art In a conventional flooring floor having a cushioning member, there is known a method in which a joist is provided in advance at a portion of the floor surface where a heavy object is placed, or a tack or the like is attached to the cushioning member. .

[0003]

However, according to the above joists, the cushioning member must be cut and formed in advance according to the furniture and the like, which makes the construction complicated and the construction cost high. However, according to the tack, there is a problem in that the surface for contacting the tack with the plywood is too small, the supporting strength is low, and a large number of tacks must be installed.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide a distortion preventing member for a flooring floor which has a simple structure, high supporting strength, and can be easily attached.

[0005]

In order to achieve the above object, the present invention relates to a base portion of a flooring floor in which a cushioning member and a floor plate such as plywood are sequentially laid on the base floor surface, and a base portion which is in surface contact with the base floor surface. A receiving portion that makes surface contact with the lower surface of the floor plate,
It is characterized in that it has a length equal to the thickness of the cushioning member, and comprises a base portion and an intermediate support portion which is continuously provided between the receiving portion, and is formed in a small size.

[0006]

[Function] When the furniture or the like is placed on the cushioning member laid on the base floor surface of concrete or the like, the distortion prevention member is pushed from the tip of the receiving portion to horizontally contact the receiving portion and the base. To do.

As a result, the lower surface of the floor plate is firmly held by the distortion prevention member, distortion due to heavy furniture such as furniture is prevented, and falling down due to an earthquake or the like is suppressed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS.

1 is a base floor surface made of concrete or the like,
Reference numeral 2 denotes a cushioning member made of, for example, foamed rubber material, 3 denotes a floor plate made of plywood or the like in which plate materials are laminated, and the cushioning member 2, the floor plate 3 and the joist 4 of the thickness of the cushioning member 2 are provided on the base floor surface 1.
Form a flooring floor 5.

Reference numeral 6 denotes a support metal fitting which is a strain prevention member, and the support metal fitting 6 is made of steel or the like and is formed in a substantially Z shape, and both horizontal pieces 6a and 6b and a vertical piece 6c are formed at right angles to each other. The one horizontal piece 6a is formed on the receiving portion, the other horizontal piece 6b is formed on the base portion, and the vertical piece 6c is formed on the intermediate supporting portion 6c.

The tip portion 6d of the receiving portion 6a is formed into an acute-angled cutting edge, and the height h of the intermediate support portion 6c is formed to be equal to the thickness of the buffer member 2.

Next, a method of attaching the above-mentioned support fitting 6 to the flooring floor 5 will be described.

A cushioning member 2 made of a foamed rubber material is laid on the base floor surface 1 and an extra joist 4 is formed at the edge of the cushioning member 2.

At this time, the receiving portion 6a having the cutting edge-like tip portion 6d of the support fitting 6 is inserted from the lower surface side of the cushioning member 2 where the front portion of the furniture 7 or the like is placed.

Next, when the base portion 6b of the support fitting 6 is rotated in the direction of arrow A, the intermediate support portion 6c of the support fitting 6 is inserted into the buffer member 2.

In this state, the intermediate support portion 6c of the support fitting 6 has the same thickness as the buffer member 2, and the receiving portion 6a.
The base portion 6b is fixed to the upper and lower surfaces of the cushioning member 2, and the upper surface is held at a constant height.

Then, a floor plate 3 is laid on the upper surface of the cushioning member 2.

The flooring floor thus formed has support strength, is easy to lay, and has excellent soundproofing and earthquake resistance.

A friction surface may be formed on at least one of the horizontal pieces 6a and 6b of the support fitting 6 to increase the friction force of the support surface.

FIG. 4 shows a second embodiment of the present invention, in which the support fitting 6 is formed by a coil 8 made of a rigid body, and one end of the support fitting 6 is further formed as a receiving portion 8a and the other end thereof is formed as a base portion 8b. The space between these end portions is formed in the intermediate support portion 8c, the height of the intermediate support portion 8c is made equal to the thickness of the buffer member 2, and the tip portion of the receiving portion 8a is formed in a sharp pointed shape. The tip portion 8d can be screwed into contact with the supporting portion of the cushioning member 2 for use.

Therefore, it has a feature that it can be easily attached to the buffer member 2.

[0022]

As described above, according to the present invention, in a cushioning member such as a furniture installation portion of a flooring floor, the length of the intermediate support portion is equal to the thickness of the cushioning member and is in surface contact with the base floor surface. Since a small strain prevention member having a receiving portion that makes surface contact with the base portion and the floor plate is inserted and mounted, it has an effect that it has a simple structure, has a supporting strength, and can be easily attached, and a safe flooring floor can be formed.
