Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor structure for a building, and more particularly to a support structure for a panel in which a panel is floated and laid on a base floor or the like.

[0002]

2. Description of the Related Art Conventionally, as a floor structure of this type, a support structure as disclosed in Japanese Utility Model Laid-Open No. 52-83316, for example, is generally used. This will be described in detail with reference to the drawings. As shown in FIG. 2, a plurality of holes (6) are provided in the floor panel (2), and a nut (7) is fitted into the hole (6). A feature is that a bolt (33) is screwed into (7) to support the floor panel (2) on the skeleton floor surface (11).

Further, as shown in FIG. 3, a foam synthetic resin (B) is laid on a concrete slab surface (S) via a cement-based or epoxy-based joining material (M), and a floor finishing material ( F), JP-A-59-6847
A floor structure as disclosed in Japanese Patent Publication No. 0 is also practiced.

[0004]

However, in the structure in which the height is adjusted by using the bolt (33) and the nut (7) shown in the former, as shown in FIG. 2, the floor panel (2) is used. Since adjustment from above is impossible, fine adjustment must be repeated each time the floor panel (2) is laid. Therefore, the level must be set in advance and enforced under strict management, and the work is extremely time-consuming.

In the latter structure shown in FIG. 3, in which the laying height of the foamed synthetic resin (B) is adjusted via a cement-based or epoxy-based joining material (M), the foamed synthetic resin is used. Even if the arrangement of the joining material (M) is suitable from the viewpoint of the grounding property and the protection property of (B), the joining material (M) has an adjusting function only in one direction of reduction. After disposing the joining material (M), the foamed synthetic resin (B) must be installed, and fine adjustment must be made to apply a pressure from above to adjust it to an appropriate level. Further, the joining material (M) requires a large amount of mass, and has a great disadvantage that it is disadvantageous in terms of weight and poor in portability on site.
The present invention has been made in view of such a number of drawbacks, and provides a floor panel (2) which is excellent in workability, has a simple adjustment, can obtain an accurate level, and has an advantage in carrying property. It is intended to provide structure.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings. As shown in FIG. 1, a floor panel supporting structure for floatingly laying a floor panel (2) on a base floor (1) or the like. There is provided a bolt (3) having a screw (31) with an adhesion preventing treatment on the head, and an upper part having a lower part serving as a buffer support part (41), a contraction part (42) in the middle part, and a tray (43). And a collar (8) for holding the bolt (3) by the preliminary support (4) and substantially supporting the preliminary support (4), and substantially laying and supporting the floor panel (2). After the epoxy resin (5) is injected and filled into the tray (43) of the preliminary support (4), which has been cured, the bolts (5) are attached without the epoxy resin (5) in the tray (43). 3) Rotate to finely adjust the height of the panel (2). And features a Succoth.

[0007]

According to the present invention, the bolt (3) is combined with the epoxy resin (5) held by the preliminary support (4) as described above, and the epoxy resin (5) is hardened to cure the floor panel (2). At this time, as shown in FIG. 1, the floor panel (2) is substantially supported by the preliminary support (4) and the collar (9), so that rough laying is completed in a short time. After that, an epoxy resin (5) is injected and filled into a tray (43) of the preliminary support (4), and after the epoxy resin (5) is hardened, the bolt (3) is removed.
For example, when the bolt (3) is rotated by an engagement structure provided on the top (32) thereof, only the bolt (3) can be rotated very smoothly by the adhesion preventing processing of the screw (31), and the preliminary support (4) When the shrinkage is adjusted by the shrinkage portion (42), an accurate level can be easily obtained, and a support structure having a high vibration and soundproofing effect is obtained in combination with the elasticity of the buffer support portion (41).

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, when the epoxy resin (5) injected and filled into a saucer (43) is hardened, it adheres to the floor panel (2) as shown in FIG. As well as exert a strong supportive force. This is not the case when this joining and integration is not desired, and it is sufficient to avoid contact with the epoxy resin at the time of filling. Further, in the present invention, since the lower part of the bolt (3) has no functional structure and can be used freely, it is possible to lay a synthetic resin foam (B) as shown in FIG. The degree is extremely large.

As described above, the means for rotating the bolt (3) is provided at the top portion (32) of the floor panel (2) so as to freely rotate from above the floor panel (2). Since the height can be adjusted after the floor panel (2) is laid, it is a preferable installation place, and the engaging structure is a reliable engagement such as a projection shape, a + groove or a − groove, and a square hole. It is imperative to shape the meshing structure that promises.

[0010]

According to the present invention, the construction described above greatly reduces the construction period of the floor panel (2) and provides an extremely accurate level. Further, the floor panel (2) can be integrated, and a floor surface having a strong structure can be obtained. Furthermore, the support structure of the present invention has superiority in sound and vibration proofing and installation, and is excellent in on-site workability.
