Description

[Detailed Description of the Invention] The present invention relates to, for example, a construction method or earthquake resistance of a raised floor.

In rooms such as computer rooms and communication equipment, double-layer upper floor boards have been used to create free access floors.

When the end of a floorboard touches a wall or pillar, the floorboard is not used, and it is connected to the floorboard with a border made of wood or other material.

On the other hand, if you have to stop laying the floorboards midway because there are no walls or pillars, or if you plan to expand the installation in the future, the floorboards may not be fixed and may end up on the adjustment platform on the support legs. , the floorboards tend to slide easily, and it is dangerous when vibrations such as shocks or earthquakes occur.

Furthermore, there were cases in which equipment on the floorboards was seriously damaged.

Various structures have been adopted to prevent these problems.

For example, they were fixed to the subfloor by welding directly to the floorboards or by screwing and nailing them.

However, there were many problems, such as the need for a lot of processing to fix the floorboards, and the number of man-hours required for welding, screw processing, etc.

It is an object of the present invention to solve these problems and at the same time to provide a simple device for preventing movement of the edge of a floorboard, which does not directly fix the floorboard.

In order to achieve the above object, the simple floor plate fixing device of the present invention erects a large number of support legs on the lower floor surface, inserts an adjustment nut and an adjustment table into the threaded portions at the top of the support legs in order, and then In a double floor consisting of a double structure with a large number of floor plates installed on the upper part of the floor plate, an L-shaped steel of the floor plate presser is sandwiched between the end of the floor plate and the adjustment ridge part toward the corner of the floor plate, The main idea is to fix and hold the lower part of the shaped steel on the upper part of the flat plate, and the lower part of the plate on the lower floor surface at appropriate angles.

An embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a front view of the embodiment of the invention, Fig. 2 is a sectional view taken along line A-A in Fig. 1, and Figs. A BB sectional view of FIG. 1 is shown.

Reference numeral 1 denotes a -L floor plate, and an angle bar 11, such as a main mold steel, is installed at the corner of the end of the upper floor plate 1 through a tile pad 2 as shown in FIG.

At the bottom of the angle bar is a support plate 9 installed on the lower floor 7.
The adjustment table 3 is inserted into the threaded part of the support leg 5 fixed to the.

The angle bar 11 is supported by the head 4 of the adjustment table 3, and the height between the lower floor 7 and the angle bar 11 can be adjusted to a predetermined level using an adjustment nut 6 on a threaded portion of the support leg 5.

The support leg 5 is fixed onto the lower floor 7 via a support plate 9 with adhesive 9a and nails 10.

A surface layer 8 is formed on the lower floor 7 to correct irregularities on the upper floor and improve the environment in the room.

21 is a skirt portion that reaches from the upper floor plate 1 to the lower floor 7.

To prevent the upper floor plate 1 from moving, an angle bar 11 mounted on the head of the support leg supports the end side surface 22 of the floor plate 1.

In order to fix the angle bar 11 on one side to the lower floor 7, attach the flat plate 1.
2, the other is assembled and tightened in the hole of the angle bar 11 with bolts 13 and nuts 14 as shown in FIG. It is measured in

The flat plate 12 is nailed to the subfloor surface 7 with the angle of the upper and lower ends set at an optimum angle θ within 35 to 55 degrees.

Although the present invention has been described in terms of preventing the upper floor plate from moving, it goes without saying that a floor plate for preventing movement can also be installed at the intermediate portion between the floor plate and the lower plate, and the floor plate can be used like a staircase.

When the present invention is implemented as explained above, the following effects can be obtained.

(1) Since the ends of the upper floor plate are held by shaped steel and further held on the lower floor surface by a flat plate, there is no vibration or lateral vibration of the upper floor plate, and the structure is earthquake resistant.

(2) Since the shaped steel and flat plate are fixed to the subfloor at a proper angle, there are fewer grounding points.

(3) The upper floor board can be freely removed because it is not directly fixed to the upper floor board but is fixed to the lower floor surface using shaped steel or a flat plate.

(4) By changing the relationship between the shaped steel at the end of the upper floor plate and the support legs in contact with it, it is possible to immediately add more upper floor plates.

Claims (1)

[Scope of utility model registration request] From a double structure in which a large number of support legs are erected on the lower floor surface -L, adjustment nuts 1 to 1 and an adjustment stand are sequentially inserted into the threaded part of the upper part of the support legs, and a large number of floor plates are installed above the adjustment stand. In the double floor, the L-shaped steel of the floor plate holder is sandwiched between the end of the floor plate and the adjustment ridge part toward the corner of the floor plate, and the lower part of the L-shaped steel is placed on the upper part of the flat plate, and the lower part of the same plate is A simple floorboard fixing device characterized in that the floorboards are fixedly held on the lower floor surface at appropriate angles.
