Description

Description: TECHNICAL FIELD The present invention relates to a floor base material used for a floor assembly of a building or the like.

Conventional technology and problems As a means for constructing a floor base by laying a large number of concrete blocks on a construction surface (for example, a concrete slab surface), JP-A-62-33967 discloses a flexible tray having a large number of compartments. We provide aggregate block type floor base materials with blocks in each room.

With this floor base material, many blocks can be laid on a tray-by-tray basis, which simplifies floor assembly and reduces construction period and costs.

Also, due to the flexibility of the tray, each block can be laid by self-adjusting so as to adapt to the unevenness of the construction surface, for example, it is optimally performed for floor assembly on a concrete slab of a reinforced concrete building, unlike the joist assembly, Suitable as a flooring base for heavy equipment and furniture.

On the other hand, the above-mentioned floor base material is used as a construction surface for the floor finishing material, and in addition to having sufficient strength to support equipment and furniture, it is desired that it is lighter in construction work, and the floor assembly height is also higher. It is required to be able to easily handle different construction sites.

The present invention provides an aggregate block type floor base material collected by the above flexible tray, while effectively utilizing the above characteristics of the base material, further improving the strength and weight, and setting the floor assembly height. It is designed to effectively deal with such issues.

Means for Solving the Problems As a means for achieving the above object, the present invention provides a floor base material of the above-mentioned aggregate block type in which a large number of blocks are collected by a flexible tray, in which the block side surface of the floor base material is separately provided. This is a composite structure in which a base material or block having a split-inducing joint made of a material is layered.

Action A large number of the above-mentioned floor base materials are laid on the floor construction surface in tray units to form a wide-area floor base material. In addition, this floor base material has an underlayer having crack-inducing joints that are cracked by the joints, while each block group collected in the tray independently moves by itself due to the flexibility of the tray. It is laid according to the unevenness of. Similarly, when a large number of blocks are layered instead of the above-mentioned base material, the same adjusting operation as above can be obtained.

Further, the base layer and the block having the above-mentioned crack-inducing joints are made of a material,
The block layer, which is layered by selecting the thickness and similarly collected by the flexible tray, is thinly formed, and a predetermined thickness (floor assembly height) is secured by the above-mentioned base layer, and the material is also the block layer. The right material can be selected in relation to.

Thus, a floor set is made by laying the above-mentioned floor base material group and constructing and supporting the floor finishing material on this.

Embodiments of the Invention The embodiments of the present invention described above will be described in more detail with reference to FIGS. 1 to 5.

In the figure, 1 is a flexible tray made of a flexible sheet of synthetic resin, metal, paper or the like, and 2 is a block having rigidity of cement type, synthetic resin type, wood type or the like. The tray 1 has a large number of partition chambers 3, for example, arranged in a grid pattern. Each partition chamber 3 is defined by a bottom wall 5a and a peripheral wall 5b.
To be held in the above block 2. Block 2 as an example
Is accommodated in the partition chamber 3 so as to be movable, in particular, vertically movable. That is, each block 2 is collected by the tray 1, and while maintaining the relative position using the tray 1 as a medium, each block is regulated by the peripheral wall 5b and the bottom wall 5a of each partition chamber 3, and along the peripheral wall 5b toward the opening. It can be moved.

As a means for collecting the block 2 on the tray 1, a cement-based fluid material is cast into each partition chamber 3 of the tray 1 and is cured as it is to form a composition. As another example, a tray 1 having a large number of partition chambers 3 is prepared in advance, and a block 2 separately formed in each partition chamber 3 is fitted. The block 2 held in the partition chamber 3 is a single-layer body or a multi-layer body. The block 2 may be adhered to the bottom wall 5a of the tray 1 or the like.

The partition chambers 3 forming the block 2 are independent of each other and are connected to each other at the periphery of the opening. That is, each partition room 3
The bottom wall 5a and the peripheral wall 5b that define the above are independent for each partition chamber 3, and are connected to each other at the upper end of the peripheral wall 5b to form a gap 6 reaching the connecting portion 4 between each peripheral wall 5b of each partition chamber 3. .

As described above, the partitioning chambers 3 have flexibility in the connecting portion 4. Therefore, each block held in each partition chamber 3 is provided with flexibility using the tray 1 as a medium. The flexible tray is made flexible as a whole, or each partition chamber is formed of a rigid body, and the connecting portion 4 is made thin to provide flexibility.

Depending on the implementation, a member for forming a wiring or piping partition chamber 3'for connecting vertically or laterally to the tray 1 of the unit floor base material and for forming a wiring or piping duct in the partition chamber 3 ' Allow 12 to fit.

The first underlayer A is formed as described above, and the first underlayer A is formed.
A second base layer B is formed by layering a base material 7 made of another material on the block side surface of the second base layer B, and the crack-inducing joint 8 is formed on the second base layer B.
To provide. The crack-inducing joint 8 reaches the layering surface from the surface of the second underlayer B and causes a crack at the bottom of the joint due to a walking load or the like to be in a movable state. Preferably, the split-inducing joint 8 is arranged so as to correspond to the partition wall of each partition chamber 3, that is, the connecting portion 4.

As described above, since the base material 7 forming the second base layer B is cracked, the cracked block and the block 2 collected on the tray 1 are integrated while the tray 1 is bent and bent. It self-adjusts and is laid without play on the unevenness of the construction surface 9.

As a means for mounting the second foundation layer B, a separately prepared foundation material 7 is placed in the uncured state of the fluid material cast into each partition chamber 3 of the flexible tray 1, and the base materials are bonded to each other. Alternatively, the base material 7 is bonded to the block 2 via an adhesive material.

As a result, the base material 7 is bound to the block 2 collected on the flexible tray 1 and the opening surface of the partition chamber 3 to be integrally laminated.

The base material 7 forming the second base layer is made of an inorganic foamed material called an ALC building material or the like.

As an example, the block 1 forming the first underlayer A is formed of reinforced concrete and used as a support surface of the finishing material 10 to give strength to heavy objects such as furniture and the like, while forming the second underlayer B. The crack-inducing base material 7 is made of a lightweight inorganic foam to reduce the overall weight and secure the floor assembly height.

As described above, one of the first underlayer A and the second underlayer B serves as a floor finishing material supporting surface, that is, a supporting surface for furniture, and the other serves as a laying surface for a construction surface such as a concrete slab. (1) The block 2 forming the base layer A and the base material 7 forming the second base layer B can be appropriately selected in terms of material and thickness.

Preferably, each block 11 is attached to each block 2 forming the first underlayer A. By using a block 11 having an arbitrary thickness which is separated from the beginning as the second underlayer B, both blocks 2 and 11 are integrally oscillated while the flexible tray 1 is bent. be able to.

EFFECTS OF THE INVENTION The floor base material is formed by laying a large number of floor base materials as described above on the construction surface. According to the present invention,
As described above, the base material or block that has been cracked to form the second base layer self-adjusts together with the block forming the first base layer with the bending of the flexible tray, and absorbs the unevenness of the construction surface. As a result, the floor construction is simplified compared to the conventional joist construction method, the construction period and construction cost can be significantly reduced, and a floor construction can be constructed as a prison.

In addition, according to the present invention, as a block or a base material for forming the first base layer and the second base layer, a suitable material such as a strength member, a light weight material, or a thickness thereof is selected to support the finishing material and the weight fixture. It is possible to secure the height and the weight, and at the same time, to secure the height required for floor construction, and to flexibly respond to the construction site.

Further, since the thickness can be secured by the second underlayer, the blocks can be thinly formed in each partition chamber of the flexible tray, and the molding is extremely easy.
