Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floor assembly structure for a house, and more particularly to a floor assembly unit that can be assembled in advance.

[Prior art] For example, the floor structure of the lower floor of a general house uses a raised floor structure in order to keep the floor moisture-proof and maintain the required height. This is an example of floor construction.

In other words, a floor joist b is erected on a stone a placed on the sub-floor ground surface to support a horizontally suspended joist C, and joists e are passed from the base d to the floor joist C in a more dense manner. A floorboard f made of decorative plywood is laid on top. Of course, in the case of a tatami floor type, a corresponding floorboard is fastened to the joists with needles, and the tatami is placed on top of it.

[Problem to be solved by the invention] Therefore, in the above-mentioned floor assembly, in order to hold the load, three
．． Estimated as a floor area of 6m square, 3 large pulls C2 at 0.9 m pitch 0.9 m for each large pull C
3 floors (total of 9) on the pitch b, and 0.225m
17 joists e are required in Pisochi. In other words, such a floor structure requires not only materials and processing costs proportional to the number of constituent elements, but also an extremely large amount of manpower for on-site construction, including floor covering.

The present invention aims to reduce the total construction cost of the floor assembly and at the same time improve the aesthetic appearance of the floor surface by unitizing a part of the floor assembly.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a parquet floor having a plurality of parquet floors having symmetrical protrusions along the longitudinal direction, and grooves corresponding to the protrusions. It consists of a plurality of elevated joists that sandwich a parquet floor, and employs a novel technical means in which the elevated joists synchronize with the parquet floor to form a comprehensive floor surface.

As a preferred form of the present invention, by combining an appropriate number of parquet floors and elevated joists in advance, and inserting through bolts between each elevated joist and tightening them together, it is possible to instantly transform the parquet into a joint unit. The interconnection of the respective coupling units according to the floor area can also be carried out very easily by tightening the bolts in the same way on both elevated joists with the parquet interposed in the middle.

``Function'' The main floor assembly unit, which is made up of alternating parquet floors and elevated joists, functions not only as a floorboard itself, but also as a joist that holds the load, and is more effective than conventional joists. The strong bending strength of the high platform joists, which have a total height of 100 cm, reduces the load applied to each joist, dramatically reducing the number of joists and floor supports per unit area. Even in the case of rolled flooring where the joists are laid directly on the concrete without being used, the elevated joists of the main floor assembly unit are sufficient to provide a wide distance between the parquet flooring and the concrete and allow storage of various wiring and piping. Provide extra space.

[Example] Hereinafter, an example of the present invention will be specifically described based on the drawings.

FIG. 1 is a side view showing a board-type floor assembly unit.The floor assembly unit 10 consists of a plurality of parquet floors 12 and a plurality of elevated joists 14 combined with the parquet floors. It is a long material with a rectangular (30 x 90 mm) cross section, and is equipped with a symmetrical protrusion 12a along the longitudinal direction on the lower half,
The height joists 14 are also rectangular (90 x 30 mm
) It is a long material in cross section, and is provided with bilaterally symmetrical grooves 14a along the longitudinal direction that match the above-mentioned protrusions 12a, and the protrusions 1
2a and the groove 14a are fitted in sequence, the parquet floor 12 is held between the left and right elevated joists 14 in a gate shape, respectively.The upper surface 14b of the elevated joist 14 is aligned with the upper surface 12b of the parquet floor 12 to be combined. is forced,
These upper surfaces 12b and 14b are synchronized to form a comprehensive floor surface. In addition, in the case of a wooden floor type like this example, for example, cypress wood is selected as the material for the parquet floor 12 and the elevated joists 14, and the contrasting wooden grain pattern and straight grain pattern that are alternately displayed on the floor surface are , which helps to highlight the elegance of the material.

FIG. 2 shows the floor assembly unit 10 mounted over a large length (not shown) from the base 16, and the synchronized floor assembly unit 10 is held by the two sides whose side ends are latched to the pillars 18. For example, as shown by the chain line in Figure 1. By combining an appropriate number of parquet floors 12 and elevated joists 14 in advance, and inserting through bolts 20 between each elevated joist 14 and tightening them together, it is possible to instantly transform it into a joint unit, which saves floor space. Interconnection of the respective connecting units according to the requirements can be done very easily by tightening bolts in the same way on both elevated joists 14 that sandwich the parquet floor 12 interposed between them, further improving the convenience of transportation and on-site construction. .

The floor assembly unit 10 in which the parquet floor 12 and the elevated joists 14 are alternately assembled in this way functions not only as a floor board itself but also as a joist that holds a load, and moreover, it has the function of a joist that holds a load. The strong bending strength of the high platform joist 14, which has an incomparable total height, reduces the load applied to each roof joist and significantly reduces the number of roof joists and floor joists used per unit area.

In addition, although the above explanation has been given for a wooden floor type floor assembly unit, it is also possible to apply it as is to a tatami floor type.
In that case, you are free to choose materials and dimensions based on profitability.6Also, even in the case of rolling flooring where the joists are laid directly on the concrete without using a joist, the elevated joists 14
Since the parquet floor 12 and the concrete are separated widely, it is more advantageous for storing various wiring and piping.

[Effects of the Invention] As described in detail above, the present invention constitutes a floor assembly uni-nod by a plurality of parquet floors and a plurality of elevated joists sandwiching the parquet floors, and connects them alternately. Since the upper surfaces of the two sides form a comprehensive floor surface, the following excellent effects can be achieved.

(1) Due to the robust structure of the floor assembly unit, especially the strong bending strength of the elevated joists, the total number of floor assembly elements can be significantly reduced, and the associated materials, processing costs, and local travel costs can be significantly reduced. be able to.

(2) Since the parquet floor and the elevated joists are assembled in a perpendicular manner, mutual strain is checked and deformation is unlikely to occur over a long period of time.

(3) The two different wood grain patterns alternately expressed by the parquet floor and the elevated joists skillfully enhance the beauty of the floor.
