Description

[Detailed Description of the Invention] The present invention relates to an improvement of a floor panel suitable for use in constructing a vibration-proof floor by using it in combination with a vibration-proofing material.

First, a conventional example will be explained based on FIGS. 1 to 3.

The flooring block shown in Fig. 1 has wooden boards 2 fixed in parallel on a channel 1, and has a rectangular plate shape with planar dimensions of approximately A=B=300 mm.
This flooring block has a structure in which a channel 1 is anchored in the mortar 4 by pouring mortar 4 on a concrete slab 3, placing the above-mentioned block on top of it, and hardening it.

The flooring board shown in FIG. 2 has wooden boards 6 fixed in parallel on joists 5, and is used in the same way as the one shown in FIG.

The unit floor shown in Fig. 3 has a plywood or sandwich panel 8 placed and fixed on a level adjuster 7 with anti-vibration rubber, and its planar dimensions are as follows:
C=D=about 900mm.

All of the floor panels shown in these conventional examples are too lightweight for floor panels used for soundproofing purposes, and therefore have poor soundproofing properties. In order to take measures against floor impact noise in these devices, it is necessary to place a heavy flooring material on top of the vibration isolating material.

If you are just thinking about making the floor panel heavier, you can change it to wooden boards 2 and 6 or plywood, etc.
It would be possible to use a high-density concrete-based material, but even if the weight could be made sufficiently large, this would create a new problem: it would be difficult to attach the wooden floor covering to the top of the floor panel. Also,
In terms of impact resistance, it was brittle, and if reinforcing bars were used to reinforce it, there was a problem in that it would interfere with the cutting and drilling of the floor panel itself.

In view of the above-mentioned circumstances, the purpose of the present invention was to create a floor panel that is heavy, easy to work with, and can be nailed to wooden floor finishing materials, and which is suitable for countering floor impact noise. The objective is to obtain a floor panel that is advantageous in terms of construction.

The technical means of the present invention for achieving this purpose is that a fiber-reinforced cement-based reinforcing plate is integrally bonded to the lower surface of a concrete-based substrate with a density of 1.0 g/cm ³ or more; , the wooden or wood-based base material is buried with the upper surface part that protrudes above the upper surface of the substrate exposed, and as a result of taking such technical measures, the following functions and effects are achieved. .

First, the effects are as follows (A) to (D).

(A) The panels are mainly made of concrete and cement, and their specific gravity is several times that of wood, so the entire panel is heavy.

(B) Even though almost all of the flooring boards are concrete or cement-based, the wooden or wood-based base material is buried in the substrate with the surface exposed, so nails (screws) are used as a means of fixing the flooring boards (floor finishing material). (stop) can be adopted.

(C) Since the reinforcing plate is made of fiber-reinforced cement, post-processing such as cutting and drilling is easier than when reinforcing with reinforcing bars alone.

(D) Furthermore, since the wood-based base material has a top surface that protrudes above the top surface of the concrete-based substrate, there may be slight differences between each floor panel during construction on site. In cases where it is difficult to obtain a horizontal level due to a difference in level, etc., the protruding wooden upper surface portion can be shaved off to easily adjust the horizontal level and height.

The effects of each of the above actions are as follows.

(B) Due to the effect of (A) above, a floor panel that is sufficiently heavy and durable as a whole in terms of the weight of the floor panel and has good soundproofing performance that is effective in attenuating floor impact sound can be obtained.

(B) Due to the effect of (C) above, a floor panel that can be easily cut and punched was obtained.

(C) Due to the effect of (B) above, a floor panel to which wooden floor finishing materials can be easily attached was obtained.

(d) Due to the effects of (B) to (D) above, a floor panel with good on-site workability was obtained.

Examples of the present invention will be described below.

[First Embodiment] See FIGS. 4 to 6.

A fiber-reinforced concrete reinforcing plate 11 is integrally joined to the lower surface of the concrete substrate 10 by adhesive or the like. The substrate 10 and the reinforcing plate 11 are squares with the same area. A wooden or wood-based base material 12 is embedded in the substrate 10 near each corner thereof. The base material 12 is formed into a truncated quadrangular pyramid shape to improve the slip-out prevention effect, and its upper surface 13 is formed on the substrate 1.
It is located above the upper surface 14 of 0.

If the base material 12 protrudes in this way, it can be appropriately shaved to suit the site conditions and can be useful for height adjustment and horizontal adjustment.
