Description

[Detailed description of the invention] This invention relates to the base structure of a concrete residential floor, and is intended to facilitate the installation of a plate-like body made of synthetic resin foam as the base material.

Conventionally, the foundation for floors in concrete houses was constructed using joists, but when the wood dries, it creates a creaking sound and the impact sound of the floor is easily transmitted downstairs, and it also takes a lot of time to construct. However, there was a problem in that the cost increased along with the rise in labor costs and the price of lumber for joists.

Therefore, recently, instead of the joist paper method, a method of laying a base material called Nedamat (trade name) made of polystyrene resin foam has been developed and has become popular.

However, when using the above-mentioned foam base material, when laying a rolling ring after laying, there is a drawback that nailing cannot be done for temporary fixing while the adhesion is completed (adhesive force is produced) in the case. was requested.

Therefore, in this invention, in order to provide a base material unit that can solve the above nailing problem, in a unit that connectably combines a plurality of plate-shaped bodies made of synthetic resin foam, the plate-shaped bodies are connected. A space is formed on the surface of the peripheral portion of the plate-shaped body so as to communicate with each other, and a reinforcing material that can be nailed is inserted into this communicating space in a state where the surface is exposed.

Next, embodiments of this invention will be described below with reference to the drawings.

Reference numeral 1 denotes a plate-shaped body made of a synthetic resin foam, and a plurality of them are combined to be connectable vertically and horizontally to form a unit.

2 is a space formed on the surface of the peripheral part to which the plate-like bodies 1 are connected, and is a space that can communicate with the adjacent plate-like bodies 1, and is a space that can be driven with a nail that matches the mutually communicating spaces 2, 2. The reinforcing material 3 is inserted with its surface exposed.

However, in the embodiment shown in FIGS. 1 and 2, the spaces 2, 2 formed in the adjacent plate-shaped bodies 1, 1 so as to communicate with each other are formed on the short sides of the plate-shaped bodies 1, 1. This is the case where the reinforcing material 3 is inserted into the spaces 2, 2.

In the figure, 4 indicates a calanelli on the concrete slab 5, and A indicates a nailing position for temporary fixing before the adhesive force of the flooring 6 is exerted.

In addition, the embodiment shown in FIG. 3 shows a case where the space 2 of the plate-shaped body 1 is formed on the long side. Although not shown, the space 2 may be formed on both the short side and the long side. It is possible.

Furthermore, in addition to the spaces 2 that communicate with each other, as shown in FIGS. 4 and 5, a space 1 for inserting a reinforcing material is formed in the lower part of the plate-like body 1 in an expanded shape or a straight shape so as not to penetrate upward. It is possible to insert the reinforcing material 8 into the space I, and when laying the plate-shaped body 1, the reinforcing material 8 is placed in advance on the calanelli or mortar dump 90 part on the concrete slab 5 to level it. For example, level adjustment can be achieved much more easily and accurately than simply adjusting with a mortar bar or the like.

After adjusting the residual level. The plate-shaped body 8 is inserted into the space 7 for inserting its reinforcing material.
The reinforcing material I for leveling may be placed in the layers in order.

At this time, the lower part of the plate-shaped body 1, which is the base material, must be constructed so as to be in close contact with the calanelli, mortar dango, etc., and an adhesive is used on the contact surface.

Next, when the finished floor is made of wood flooring, reinforcing material 3 is placed in the mutually communicating spaces 2, 2 formed on the peripheral surface where the adjacent plate-like bodies 1, 1 are connected.
Although the flooring 6 is fixed to the plate-like body 1 with an adhesive, the flooring 6 can be nailed to the reinforcing material 30 portion as temporary fixation until the adhesive force is exerted.

The foam used to form the plate-like body 1 used in the above implementation is one made by adding a foaming agent to a synthetic resin, and polystyrene is particularly suitable. Foams made from copolymers and the like are suitable.

In addition, although not shown in the figures, vibration isolating materials may be attached to some of the upper and lower parts of the reinforcing materials 3 and 8 of each part.

Also, in the figure, ventilation holes on the surface of the plate-like body and thinning holes on the back surface are omitted.

As described above, according to the base structure of this invention, the reinforcing material that can be nailed is inserted into the space communicating with the adjacent plate-shaped bodies with the surface exposed, so that the reinforcing material can be inserted into the plate-like shape. It is convenient because it can be shared between the bodies and used for connection.

Not only is it easy and effective to nail the flooring, it also strengthens the board, and even when a large load is applied to the floor, the amount of deflection (sinking) of the floor surface is extremely small, and the board Even if the shaped body 1 is highly foamed (low density), it can withstand use sufficiently and is useful for cost reduction.

As described above, the laying work becomes easy and reliable, and quick and short-term construction can be realized, which can also help reduce construction costs.

Therefore, it is particularly effective when used as a base material unit for wood flooring, etc., and is extremely effective in conjunction with the characteristics of foam, which are excellent heat insulation and heat retention, low moisture permeability, and excellent sound insulation performance. Demonstrate practicality.
