Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floor component that constitutes the floor surface of an office automation room, an intelligent building, or the like.

[Prior Art] Conventionally, in various types of concrete buildings, the floors have been constructed by laying resin flooring materials on the subsurface of the floors, and the floor components are made of lumber mainly made of polyvinyl chloride. A rum type was used.

However, in office automation rooms, intelligent buildings, etc., it is necessary to run various signal cables and power cables under the floor, so recently concrete floor components with legs at the four corners have been used. Spaces for passing various cables are also formed between the subsurface of the floor and the floor surface.

[Problems to be Solved by the Invention] However, as mentioned above, concrete products with legs at the four corners are heavy and difficult to transport and lay down, and the exposed surface can cause injury to workers. It had the disadvantage of poor workability, such as partial collapse during work.

The present invention aims to overcome the drawbacks of the conventional products, and is made by blow molding thermoplastic resin to form a hollow double wall structure, and a part of the lower surface thereof is provided with a fixing portion for a supporting member. This structure makes it lightweight, strong, and has excellent cushioning, soundproofing, and tactility.
The object of the present invention is to provide a floor component that can be laid on the floor surface with support members maintaining the required height spacing, and that allows various cables, etc. to be arbitrarily passed through the bottom surface thereof. be.

[Means for Solving the Problems] The present invention is configured as follows as a technical means for achieving the above object.

That is, the structure is a floor component that is laid one after another on the base surface of the floor to form the floor surface, and is formed into a hollow double wall structure by blow molding of thermoplastic resin, and a part of the lower surface is made of This floor structure member is characterized by forming a fixed portion of a support member that maintains a predetermined height between the support member and the base surface of the floor.

[Function] The floor component according to the present invention is formed into a hollow double-walled structure by blow molding a thermoplastic resin, so it is lightweight as a whole and has high strength.

In particular, because of its hollow double-walled structure, it has excellent cushioning properties, soundproofing properties, and tactility. In addition, a part of the lower surface has a fixing part for the support member, so it can be fixed to the base surface of the floor there, and if the support member to be fixed is fixed, the floor component will be attached to the base surface of the floor. The distance corresponding to the height of the support member can be maintained.

[Example ] Embodiments of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a plurality of floor constituent members, and these floor constituent members 1 are fixed to a large number of support members 3 erected on the floor base 2, and are successively laid down. The floor is constructed by laying a carpeter l-4 on the upper surface. Various cables and the like can be passed through the space 5 between the floor component 1 and the floor subsurface 2.

The floor component 1 is constructed as shown in FIGS. 2 and 3. That is, the floor component (2) is a square shaped hollow double-walled structure formed by blow molding thermoplastic resin, and at the four corners of the lower surface there are support members in which the lower side walls are recessed into the upper side walls. A fixing part 6 for fixing the parts 3 to 3 is formed. The support member 3 has an integral fixed foot plate 7 at the lower end and an integral support plate 8 at the upper end, and the fixed foot plate 7 of the support member 3 is fixed to the concrete subfloor surface 2 by anchor bolts 9. , the support member 3 is erected. Each floor component 1 has its four corner fixing parts 6 fitted into the support plate 8 of the support member 3, and the fixing parts 6
By passing a set screw or the like between the hole IO provided in the support plate 8 and the hole in the support plate 8, the support plate 8 is successively laid out with the support member 3 interposed therebetween. The support plates 8 of the support members 3 at the four corners of the floor are formed in an L shape to support the corners, and the support plates 8 of the support members 3 at the middle part are used to connect the adjacent floor constituent members 1.1. It is formed into a rectangle.

A leg member 11 is attached to the middle part of the floor component 1.
There is. This leg member 11, as shown in detail in FIG.
During blow molding, the lower side wall is recessed into the upper side wall to form four parts 12.
A synthetic resin leg fixing member 13 is inserted into the four parts 12, and after molding, the leg member 11 is inserted into the leg fixing member 13 and fixed. If the leg member 11 of the intermediate portion is configured to be a bolt and the leg fixing member is screwed as a nut, the height of the intermediate portion can be appropriately adjusted when laying the floor.

Note that the intermediate leg member 1.1 can also be omitted.

Since the lower side wall is formed with a large number of ribs 14 which are recessed and integrally welded to the upper side wall, it not only has high strength against loads but also has excellent cushioning and soundproofing properties.

Electric conductor wires 15 are inserted diagonally into the lower side wall of the floor component 1 to connect the fixing parts 6 at the four corners.
Each of the spread floor members 1 can be grounded via the support member 3 fixed to its fixed part 6, which is effective in preventing static electricity.

Note that the hollow portion of the floor component 1 may be filled with a fire extinguisher, or may be filled with various fillers for reinforcement. When the hollow part is filled with filler, the filler is not exposed on the surface, so it will not injure the operator or partially collapse during work. The extinguishing agent to be filled into the hollow part of the floor component 1 is a liquid such as water, an aqueous solution of potassium carbonate, or a powder such as sodium hydrogen carbonate, potassium hydrogen carbonate, or ammonium dihydrogen phosphate.
This may be carried out at any point during the molding of the floor component 1, after molding, or during the construction of the floor.

The floor component l is composed of blow-moldable thermoplastic resins such as high-density polyethylene, medium-low density polyethylene, polypropylene, polyamide, polybutylene ethylene leftate, polycarbonate, modified polyphenylene oxide, polyarylate, etc. It is also possible to mix flame retardants, conductive agents, etc. into the resin. Note that it is also possible to use a blend of the above resin with another resin, for example, a recycled resin.

In addition, as shown in FIG.
As for the two-layer structure of the skin layer 1b and the skin layer 1b, the skin layer 1b may be made of a highly conductive resin or have a conductive painted surface, and in this case, grounding using the inserted electrically conductive wire 15 is extremely effective.

The floor component 1 configured as described above is made of thermoplastic resin and has a hollow double wall structure, so it is lightweight.
It has great strength. Therefore, a floor constructed by laying the floor component 1 on the base surface 2 of the floor has high strength against loads, and also has excellent cushioning properties, soundproofing properties, and tactility.

Since a space 5 is formed by the support member 3 between the floor component 1 and the floor surface 2, various cables and the like can be arbitrarily passed under the floor.

[Effects of the Invention] The present invention provides a floor component that is sequentially laid on the base surface of the floor to form the floor surface, and is formed into a hollow double wall structure by blow molding a thermoplastic resin, and a part of the lower surface is for,
Since it forms a fixed part of the support member that maintains a predetermined height between the floor and the subsurface, it is lightweight, yet has high strength, and has good cushioning properties, soundproofing properties, and tactility. It is possible to obtain a floor constituent member which can be laid on the base surface of the floor with a required height interval maintained by supporting members, and through which various cables etc. can be arbitrarily passed through the lower surface side.
