[Industrial applications]

 The present invention relates to a floorboard for a building, and more particularly to a floorboard capable of constructing a finishing floor on a concrete foundation floor.

[0002]

[Prior art]

 In recent years, the floors of steel-framed condominiums and buildings have been constructed by placing square-shaped unitary floorboards in a floating state by a plurality of support legs on a bare concrete foundation floor. The structure is such that the floorboards are adjacent to each other at the same horizontal height and a finished floor is constructed on the entire surface of the foundation floor. And a carpet like tile carpet is laid on the top of the finishing floor. Therefore, a space having the length of the supporting legs is formed between the foundation floor and the finishing floor, and the space is used to install electric wiring, gas, and water pipes.

FIG. 6 and FIG. 7 show an example of a floorboard for constructing a conventional finishing floor. The floorboard a is usually formed in a square body having a thickness of about 3 cm and a size of 500 × 500 mm. It is made of concrete and can be held horizontally on the foundation floor c of the building by the support legs b attached to the four corners. The floor board a can be adjusted in height with respect to the foundation floor c by support legs b. For this reason, as shown in FIG. 8, the floor plate a is embedded with a cylindrical fixing tool e having an inner periphery formed with a thread groove d. The height can be changed by screwing it inside.

As shown in FIG. 7, the above-mentioned floor board a is installed on a concrete foundation floor c left untouched in a building, and as shown in FIG. 9, the four sides of each floor board a having the same plane height are closely contacted. Then, a plurality of sheets are installed on the entire surface of the foundation floor c. By rotating and adjusting the support legs b as described above, all the floorboards a have the same plane height. Therefore, a driver groove such as a minus or a plus which allows the tip of the driver to enter the upper surface of the support legs b. (Not shown) is formed, and the support leg b can be rotated from above the fixture e. Therefore, the height of each floor board a can be adjusted even when a plurality of floor boards a are installed adjacent to each other as shown in FIG.

[0005]

[Problems to be solved by the device]

 The above-mentioned single floorboard a forming the conventional finishing floor is very heavy because it is made of concrete, and the work burden on the worker is large only by carrying it. Also, the fixture e to which the support leg b is attached is embedded in the floor board a, but since it is embedded when the floor board a is manufactured, be careful not to let concrete enter the fixture e. There is a need to. If concrete enters the fixture e and solidifies, it is very troublesome to remove the concrete, and in some cases, it becomes a defective product.

Further, since the thickness of the floor board a is about 3 cm and the fixture e is only its length, the connecting portion with the supporting leg b is short, and the height adjusting length of the supporting leg b is limited. Met. Moreover, since the connecting portion is short, the length of the supporting leg b is limited in order to improve the stability of the floor board a in the horizontal state, and the space between the floor board a and the foundation floor c is not enough to form a space. there were.

Further, as shown in FIG. 5, it is convenient to carry the floor board a on the two symmetrical sides of the single floor board a, and it can be installed in contact with the adjacent floor board a or as shown in FIG. A groove g is formed in order to lift only a certain floor plate a from this state. However, since this groove g is large, a large space is formed when the grooves g of adjacent floor boards a face each other as shown in FIG. Therefore, even if tiled carpet is laid on the surface of the finished floor, the space is still empty, so when a thin heel such as high heels is placed on this, there is an instability that the carpet is dented.

In view of the above-mentioned conventional floorboard, the present invention makes the entire floorboard made of wood and increases the length of the fixture for attaching the supporting legs so that the connecting portion between the two is sufficiently long and the weight is light. The purpose is to provide a floorboard that is easy to carry and has a stable installation condition.

[0009]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is to install a suitable space on a concrete foundation floor of a building, and in the floor board whose horizontal height can be adjusted, the floor board 1 is made of wood. It is characterized in that the support leg 2 is vertically movably attached to a fixture 3 which is detachably provided at four corners, and a long hole 4 for locking is formed inside the two symmetrical sides.

The floor plate 1 is a plywood plywood, and the fixture 3 is such that a square nut 8 is integrally fixed to the lower end of a tubular body 7 having a length equal to or smaller than the thickness of the floor body 1, and the tubular body 7 and the nut. A thread groove 9 into which the screw thread 5 of the support leg 2 can be screwed is formed on the inner peripheral surface that communicates with the entire length of the pipe 8, and a screw thread 10 that can be screwed into the floor plate 1 is formed on the outer periphery of the cylinder 7. It is characterized by being engraved.

 An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows the entire floorboard according to the present invention. This floorboard 1 has supporting legs 2 at four corners of a rectangular plate, and the horizontal height is adjustable, which is the same as the conventional floorboard. In the present invention, the floor plate 1 has a plate thickness of about 3 cm, is made of 500 × 500 mm square wood, and the fixing tool 3 that supports the supporting legs 2 attached to the four corners of the rectangular plate in a vertically movable manner is a square. It is detachable from the bottom surface of the plate, and the fixture 3 is made longer than the plate thickness of the rectangular plate to lengthen the connection part with the support leg 2 and a small length for hooking inside the two symmetrical sides of the rectangular plate. It is characterized in that it is formed so as to penetrate through the hole 4.

FIG. 2 shows a state in which the fixture 3 provided on the floor plate 1 and the support leg 2 are connected to each other. The support leg 2 has a thread 5 formed at the upper end of a metal round bar and at the lower end thereof. Is provided with a rubber cap 6 for slip prevention and soundproofing. Further, as shown in detail in FIG. 3, the fixture 3 has a hexagonal nut 8 for fastening integrally fixed to the lower end of the tubular body 7, and is fixed to the inner peripheral surface communicating with the entire length of the tubular body 7 and the nut 8. A thread groove 9 into which the screw thread 5 can be screwed is formed, and a screw thread 10 that can be screwed into the floor plate 1 is engraved on the outer periphery of the cylindrical body 7. The cylinder 7 has a length that is the same as or slightly smaller than the thickness of the floor plate 1, and is mounted by screwing it from the lower surface of the floor plate 1, but the nut 8 is in a state of protruding from the lower surface of the floor plate 1, The upper end of the body 7 does not project to the upper surface of the floor plate 1.

The floorboard 1 of the present invention has the above-mentioned structure, and at the time of use, holes are formed in advance at the four corners of the floorboard 1 which are smaller than the thread diameter of the thread 10 formed on the outer periphery of the cylindrical body 7. The cylinder 7 is screwed in from the lower surface of the floor plate 1 along the holes. If the nut 8 is screwed in until it comes into contact with the lower surface of the floor plate 1, the tubular body 7 is fixed in the floor plate 1 and does not fall out. A washer 11 may be provided between the nut 8 and the floor plate 1.

After attaching the fixtures 3 to the four corners of the floor plate 1, the screw threads 5 of the support legs 2 are screwed into the screw grooves 9 of the respective fixtures 3 from below, and the respective support legs 2 are attached to the foundation floor of the building. Stand on top of 12. Such a floorboard 1 may be installed on the foundation floor 12 in a state in which the four sides are in close contact in the same manner as in the conventional case, and a finishing floor can be constructed by a plurality of floorboards 1. As shown in FIG. 4, a driver groove 13 such as plus or minus is formed on the upper end surface of the support leg 2. Therefore, after all the floor boards 1 are installed on the foundation floor 12, the fixture 3 The horizontal height of all floorboards 1 can be adjusted to the same level by rotating the support legs 2 using a screwdriver from above.

A long hole 4 is formed inside two symmetrical sides of the floor plate 1, but it has sufficient robustness. A hooking member (not shown) in which the lower part of a thin metal rod is bent into an L shape. The floorboard 1 can be carried and installed by using. That is, the L-shaped portion of each hook member may be inserted from the long hole 4 and the bent portion may be hooked on the lower surface of the floor plate 1, and the floor plate 1 can be transported by holding the upper part of the hook member. Also, it can be installed on the foundation floor 12. Furthermore, it is possible to lift only a certain floorboard from the constructed finishing floor.

The wood forming the floorboard 1 may be a single plate, or may be veneer plywood having a predetermined plate thickness in terms of weight reduction, robustness and price. Although the nut 8 of the fixture 3 has been described as a hexagonal case, it is not limited to this and may be a square or other shape as long as it can be tightened by a spanner, a wrench or the like and can be rotated. Further, the case where the floor plate 1 is a square body has been described, but it may be a rectangular body as shown in FIG. The support legs 2 may be provided.

[0017]

[Effect of device]

 As described above, according to the present invention, since the finishing floorboard 1 which can be installed on the concrete foundation floor 12 of the building with a proper space is made of wood, it is possible to reduce the overall weight and to carry it. Floor construction work becomes easier and the labor force of the workers can be reduced.

The fixture 3 that allows the floor plate 1 to be adjusted up and down and to which the support legs 2 for holding the floor plate 1 in a horizontal state is attached is formed by a tubular body 7 and a nut 8. Since it can be screwed in and fixed, and the thread groove 9 is formed in the entire inner circumference of the cylindrical body 7 and the nut 8, the thread groove 9 can be made longer than the plate thickness of the floor plate 1. Therefore, when the thread 5 of the support leg 2 is screwed into the screw groove 9, the connection length becomes long, so that the support leg 2 is in a stable standing state, and the support leg 2 can be lengthened. Therefore, the space between the floorboard 1 and the foundation floor 12 can be enlarged, and a sufficient space for electric wiring, piping for gas, water, etc. can be secured. Furthermore, the space between the floorboard 1 and the foundation floor 12 can be used as a storage space.

Since the fixture 3 can be attached to and detached from the floor plate 1, when a particularly heavy device such as a closet or a rocker is installed on the finishing floor, this part of the floor plate 1 is thick to support the load. When the support leg 2 is used, the fixture 3 can be replaced with a large diameter one.

Further, since the long hole 4 for carrying the floorboard 1 is small, when the carpet is laid on the upper surface, it is not dented by the heel of the shoe. In particular, since the long holes 4 are formed inside the floorboards 1, when the floorboards 1 are spread in an adjacent state, no gap is formed between the floorboards 1 and the entire finished floor is as if it were a single plate. It will be.
