Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This application relates to a floor member laid on a floor board so that communication cables and the like can be wired between the floor member and the floor board.

Conventional technology Conventionally, height-adjustable pedestals, which are made by screwing movable legs onto mounting legs, are placed at the four corners of a rectangular floor panel made of, for example, a steel plate, and which can be adjusted from the top surface of the floor panel. There are well-known floor members that are installed on concrete floor plates to enable wiring of communication cables, etc.; Pillars that are grounded above and not on the floor plate are
The height is adjusted by adjustment and operation, and in this way, a large number of floor members are laid along the upper surface of the floor board.

Further, a leg cap made of an elastic material such as synthetic rubber is attached to the lower part of each pedestal in order to provide a cushioning effect to the floor surface.

Problems to be Solved by the Invention However, since the above-mentioned conventional leg caps are solid and exert a cushioning effect through elastic deformation of the leg caps, the degree of cushioning is small and it is difficult to recover from elastic deformation. However, when the leg cap is made of a flexible elastic material in order to increase the cushioning effect, the load capacity is impaired.

In addition, in the conventional configuration, there is a risk that the movable legs of the pillars may become loose during the handling of the floor members, and the protruding lengths of the pillars may differ from pillar to pillar before installation, making the work of laying them on the floor board cumbersome. In addition to having a
There was a defect in that the height of the adjusted pedestals fluctuated over time due to external vibrations that were applied to the floor surface, such as when walking, causing wobbling on the floor surface.

Therefore, the present application aims to solve the above-mentioned disadvantages of the conventional method.

Means for Solving the Problems In order to achieve the above-mentioned object, the present application has a pedestal installed vertically at the corner position of the floor panel, and the bottom end of the pedestal is made of an elastic material and has an umbrella shape at the bottom. It is characterized in that a cylindrical leg cap having a curved ground contact portion is fitted, and a convex portion is integrally provided on the top of the inner surface of the ground contact portion.

In addition, the pedestal is vertically installed at a corner position of the floor panel, and has a mounting leg part with a screw hole in the center, and a flange part and a fitting part in the lower part of the screw shaft that is screwed into the screw hole. When the leg cap has a movable leg portion, the cylindrical portion of the leg cap extends to the mounting leg portion.

Function: When a large number of floor panels are laid on a floor plate made of concrete, for example, the ground contact portion is deformed to a slightly wider diameter due to its own weight, and an air chamber is formed within the ground contact portion.

In this laid state, when a load is applied to the floor surface, the ground contact portion elastically deforms and the air within the ground contact portion is compressed to buffer the load. When the load disappears in this state, the air in the ground contact area and the restoring elasticity of the ground contact area combine to immediately restore the original state.

Embodiment The following is a detailed explanation of the embodiment of the present application based on the drawings.
For example, a square floor panel (1) with a side of 50011 is made of a steel plate with an intermediate material bent in a wave shape interposed between the upper and lower plates having side pieces on the periphery. The support plate (2) is made of a long steel plate, and the support plate (2) has height-adjustable pillars (3), (3) at the front and rear positions. A floor member main body that is suspended and fixed and has through holes (5) for adjusting the adjuster operation arranged in the four corners of the floor panel (1), and the pillar (3) is connected to the receiving plate ( The upper end is fitted into the mounting holes (6) made at the front and back positions of the horizontal part of (2), and the metal receptacle is integrally hung vertically on (2) and has a screw hole (7) in the center. A ring-shaped mounting leg (8), a screw shaft (9) that screws into the screw hole (7) of the mounting leg (8), a large diameter flange (10) at the bottom, and a fitting with a flat bottom. A metal movable leg part (12) is integrally connected to a joint part (11), and the upper surface of the screw shaft (9) is provided with the floor panel ( 1) is provided with an operating section (9)a which is rotatably operated from the top surface via a tool. (14) is the pillar (
The leg cap (14) fits the fitting part (11) of 3), and the leg cap (14) has a fitting part (11) and a collar part (10).
) and the lower part of the mounting leg (8), and a cylindrical part (15) long enough to fit over the lower part of the mounting leg part (8), and a grounding part (16) curved like an umbrella. The grounding part (
A convex portion (17) is provided on the top of the inner surface of the leg cap (16). It is continuously fitted into the lower part of the mounting leg (8).

Therefore, a floor panel (1) and a pair of support members (4)
, and (4), the floor member A is, in principle, in the shortest state of the pedestal (3) with the screw shaft (9) sufficiently screwed into the mounting leg (8), and is finished with concrete, for example. When a large number of floor members are placed on the floor board B, the ground contact part (16) deforms to a slightly wider diameter due to its own weight, and air is trapped inside the ground contact part (16). A chamber is formed.

In this installation state, for the pedestal (3) whose leg cap (14) rises above the floorboard, insert a tool into the through hole (5) that communicates from the top of the floor panel (1), and insert the tool into the screw shaft ( The movable leg portion (13) is engaged with the operating portion (9)a of
), and in this way, all the leg caps (14) are grounded almost equally on the floor board to form a floor surface.

Note that a covering board such as a car vent is stretched over the upper surface of the floor panel (1) laid along the floor board.

When a load is applied to the floor surface laid in this manner due to walking or movement of a transport vehicle, the ground contact portion (16) further elastically deforms, and the air within the ground contact portion (16) is compressed, further When a strong load is applied, the protrusion (1
7) touches the floor and is elastically deformed. In this state,
When the load disappears, the ground contact portion (16) immediately returns to its original state due to the action of the restoring elasticity of the ground contact portion (16) and the convex portion (17) and the restoring force of the air within the ground contact portion (16).

Effects of the Invention As described above, according to the present application, an air chamber is formed in the ground contact part when the leg cap is in contact with the floor board, so that when a load such as when walking is applied to the floor surface, the load is reduced. According to
As the ground contact area deforms elastically, the air in the air chamber is compressed to provide a high cushioning effect, and when the load disappears from this state, it is restored by the restoring force of the compressed air and the restoring elasticity of the ground contact area. This can be carried out quickly, and therefore it is possible to provide a floor member with excellent load resistance and restorability. In particular, according to the structure of claim 2, even the convex portions can be moved on the floor board against strong loads. Since it is elastically deformed when it comes into contact with the ground, it exhibits superior effects in terms of load resistance and restorability.
According to the described configuration, the adjustment height dimension of the movable leg portion of the pillar does not change during handling of the floor member or after its installation, which is convenient for handling the floor member, and prevents rattling over time. It has the advantage of being able to be constructed on a floor surface that does not cause scratches.
