Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a floor panel for a building,

More particularly, the present invention relates to a bottom plate for a building, and more particularly, because the side molding portion and the casing flange of the bottom plate are fastened and fixed to each other in a bent state, separation and disconnection of the molding portion and the casing flange can be prevented, The bottom plate is firmly fixed tightly by the molding part while being seated on the casing flange and is fixed so as to prevent the moisture and foreign matter from penetrating into the casing to prevent corrosion of the casing and to improve the durability and rigidity of the bottom plate And more particularly, to a flooring board for building having a frame separation preventing molding structure capable of achieving economical efficiency by significantly improving casing thickness.

In general, a floor plate called a "Free Access Floor" or "OA Floor" is used to easily wire an electric wire or a communication cable at the floor of an office building or a building, It is installed with a passage space of a certain height on the floor so as not to be exposed and to give a good feel to the floor of the room and to utilize the indoor space appropriately.

That is, there is a problem that the indoor space is not properly used as well as the aesthetics of the indoor space because the communication cable or the electric wire is directly exposed to the floor in the room of the building. In order to solve such a problem, Since the plate material is spaced apart from the floor surface by a predetermined height and the communication cable or wires are arranged through the passage space formed between the floor plate and the floor of the room, the communication cables and wires installed on the floor of the room are prevented from being exposed .

The conventional bottom plate is formed of a rectangular plate having a predetermined thickness and is formed by joining an upper plate member and a lower plate member made of a metal plate in the form of a casing and filling the inner space with cement mortar for durability and rigidity .

As shown in FIG. 1, a casing 1 of a square plate, a bottom plate 2 seated on the casing 1, a cement mortar 3 and a casing (not shown) 1 and a molding part 4 for fixing the periphery of the bottom plate 2.

In the conventional floor plate having such a structure, since the cement mortar is filled in the inside, the installation work is difficult due to heavy weight in the transportation process, and there is a problem that a safety accident occurs in the installation process.

Further, since the cement mortar filled in the casing must undergo a curing process, there is a problem that the curing mortar is not cured properly due to the curing time which is caused by the curing time generated in the curing process of the cement mortar There is another problem that a cement mortar is broken or a defective product is generated by a crack.

In addition, since the adhesion between the casing made of a metal plate and the cement mortar is poor, the gap between the casing and the cement mortar is generated during the curing process. Therefore, the cement mortar is cured without being fixed. The cement mortar cracks frequently due to the impact.

Further, when cutting and cutting a part of the bottom plate in the installation process, dust generated by the cement mortar provided in the casing is severely generated, cutting cutting work is difficult, and the cement mortar is cracked.

In addition, since the floor plate material installed on the floor of the room is removed during the process of re-working the floor of the room, it is impossible to recycle the removed floor plate material, which is very inefficient in terms of resource recycling.

Further, when the bottom plate is made of tile, a frozen phenomenon occurs in the winter, so that the bottom plate made of the tile is separated from the cement mortar, damaged or damaged, Another problem is that cracks are generated.

In addition, there is a problem that the material cost is increased due to a thick upper portion, and noise is generated during walking.

In the conventional art, a flooring material for building construction, which is a registration room 20-0134763, has been developed. In this construction, the flooring material is continuously installed on a plurality of pillars installed on a concrete floor, And a mortar which is injected through an injection hole bored in the bottom surface of the lower plate and is filled in a space inside the casing, as a main component .

Such prior art techniques are capable of preventing ringing through floor slabs as they are filled with cement mortar, but the problems caused by filling the cement mortar inside the casing are still solved I can not do that.
