Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention can be applied to the foundation floor surface of buildings such as general residences, offices, and hospitals. This invention relates to a floor structure that is constructed of a fixed length wooden floor material and a floor covering frame.

0002

[Conventional technology]

As for the floor structure of the above-mentioned building, first, 45mm Line up square joists, nail a 0.9m x 1.8m piece of plywood on top of it, and then For example, if a surface layer such as carpet or plastic tiles is attached to the top surface. There is.

0003 Recently, especially in ordinary houses, the surface layer of carpet is prone to dust mites, etc. It is said that plastic tiles can cause asthma and are not good for health. Due to the coldness and slippery nature of the Wood-based flooring materials with wood glued to them are prized for their rustic and luxurious feel. It has become.

0004 However, if the joists are lined up on the foundation floor as shown above, then wooden flooring material is placed on top of the joists. With conventional floor structures in which floors are fixed with nails, vibrations caused by impacts on the floor material can cause damage to the foundation floor. Because it is transmitted through the surface to the downstairs and neighboring rooms, complaints may arise especially from the downstairs residents. For this reason, apartment complexes have no choice but to re-apply carpet over the flooring material. Measures are being taken to reduce the propagation of noise and vibrations, such as by installing carpets.

[0005] In addition, various electrical appliances are being installed in ordinary homes, and the wiring for their power sources, etc. The walls are wrapped around the floor, making it unsightly, but in offices it spoils the aesthetics and improves the space. In order to make effective use of the wiring, various types of wiring can be placed under the floor. There is a demand for a floor structure that is easy to remove and move.

[0006]

[Problem that the idea aims to solve]

This invention prevents the propagation of vibrations caused by impact on flooring materials, and To provide a floor structure that is easy to remove and is also easy to remove.

[0007]

[Means to solve the problem]

The floor structure of the present invention has an interior that is wider than the opening width along the longitudinal direction on the back side. A wooden floor material of a fixed length is provided with a cross-sectional fitting groove, and is engaged with the fitting groove. A synthetic resin bedding frame with a protrusion on the top side and an elastic piece fixed on the bottom end. The upper surface of the floor covering frame can be slid in the longitudinal direction on the back surface of the wooden floor material. Is it characterized by being installed on the foundation floor in a closely engaged state? Therefore, problems can be solved.

[0008]

【Example】

FIG. 1 is a perspective view showing an embodiment of the floor structure of the present invention. Back side of wood floor material 1 On the surface side, there are two fitting grooves formed in the shape of a dovetail along the longitudinal direction of the floor material 1. A groove 11 is provided. This floor material 1 is made of plywood with a width of 300 mm and a length of 1.8 m. , A thin piece of precious wood is pasted on its top surface, and there are ridges 12 or grooves 1 around its four circumferences. It has a 3-piece ridged finish. A cross section perpendicular to the longitudinal direction of the fitting groove 11 The shape is an inverted trapezoid, with the inside wider than the width of the groove opening.

[0009] The floor covering frame 2 that supports the wood-based floor material 1 is made of hard thermoplastic synthetic resin. It is a roughly box-like body manufactured by extrusion molding, measuring 250mm in length and width and 45mm in height, with nine legs on the bottom. The base of the elastic piece 3 is embedded and fixed in the lower end of each leg. each elastic piece 3 is a protrusion made of ethylene-vinyl acetate copolymer with a hardness of 75 (JIS K 6301). Consists of pieces with a protruding height of 5 mm. The bedding frame 2 has suitable ribs 22 as shown in FIG. By providing a gap 23 or a missing portion 23, the weight can be reduced while maintaining the specified strength. The aim is to make molding easier, shorten molding time, and reduce molding distortion. Furthermore, the bedding frame An inverted trapezoidal projection 21 that engages with the fitting groove 11 is provided on the upper surface side of the body 2. Ru. The upper surface of the floor covering frame 2 can be slid on the back surface of the wooden flooring material 1 in the longitudinal direction. The structure is designed to closely engage with the roof, and in such a state it is installed on the four sides of the foundation floor. , insert the protrusions 12 of another floor material 1 into the grooves 13 of the floor material 1, and assemble them one by one. The predetermined range is covered.

0010 FIG. 2 shows, as an example, that each protrusion 21 of three floor covering frames 2 Indicates that it is being installed on the 4th surface of the foundation floor while being inserted into the fitting groove 11 of material 1. It is a drawing. Figure 1 shows a wooden flooring material 1 with one row of floor covering frames 2 inserted. However, if the width of the wooden floor material 1 is, for example, 900 mm, multiple rows In some cases, the bedding frame 2 is arranged along the longitudinal direction.

[0011] In the above embodiment, the protrusion 21 inserted into the fitting groove 11 has a cross-sectional shape of the fitting groove 11. Although it has a shape that makes sliding contact almost on the entire surface, the back side of the wooden floor material 1 and the floor covering frame If the upper surface of the body 2 can be slidably and closely engaged, a portion of the protrusion 21 may be cut off. It may also have a missing shape.

0012

[Effect of the idea]

Since the floor structure of the present invention is configured as described above, the lower end of the leg of the floor covering frame is Due to the action of the fixed elastic piece, the impact on the wood flooring material is absorbed and The degree to which vibrations were propagated downstairs and to neighboring rooms was attenuated.

[0013] In the floor structure of this invention, the wooden flooring material is supported from the foundation floor by the bedding frame. Therefore, do not use long joists. Therefore, fixing the joists to the foundation floor Also, since there is no need to fix the floor material and joists, installation is easy and can be carried out in a short time. can do. It is also easy to remove the flooring material upon request. , power wiring can be easily installed, changed, and removed. Missing on each side of the bedding frame By providing a section, wiring can be freely routed in each direction on the foundation floor surface at the bottom of the floor covering frame. It can be circulated.

[0014] In addition, the floor structure of the present invention can be used as a Japanese-style tatami mat by setting the height of the bedding frame appropriately. It is possible to easily change the room to a Western-style room with wooden flooring, and then return it to a Japanese-style room. It's also easy to do, so you can enjoy the different atmosphere depending on the season.
