Description

Description: TECHNICAL FIELD The present invention relates to a floor base material that is preferably used when assembling a floor onto a concrete slab such as a building.

BACKGROUND ART As shown in Japanese Patent Publication No. 57-20465, a floor base material is known in which a large number of aggregate blocks are connected by a flexible connecting material, and these aggregate blocks are made by casting concrete or the like. Has been formed. This floor base material has flexibility while individual blocks are connected to each other by a flexible connecting material, and is used as a floor base material on a slab of a concrete building.

Problems to be Solved by the Invention The floor base material has a side surface as a raising means for securing wiring and piping space and a side surface as a floor material supporting means for firmly supporting heavy equipment and fixtures, The above-mentioned floor base material has the advantage that it can be easily leveled on the floor construction surface due to its flexibility, but on the other hand, in order to obtain the supporting strength of the above-mentioned heavy fixtures, the material of the aggregate block should be made hard and robust, and the underfloor space However, if it is made bulky in order to ensure that the weight becomes extremely high, the portability and workability will deteriorate.
On the other hand, if lightweight materials such as lightweight concrete are used for the purpose of weight reduction, there is a contradictory problem that the impact resistance and the like decrease, and it is difficult to satisfy both conditions of bulking and strength. .

The present invention can secure the strength such as impact resistance added from the floor finishing surface side while enabling the floor base material to be bulky,
Moreover, the present invention provides a floor base material which can be made lighter as a whole and can effectively utilize the above-mentioned flexibility.

Means for Solving the Problems Thus, the floor base material according to the present invention has a large number of pedestals having legs at four corners formed by punching and bending a metal plate, and the pedestals are formed in a grid pattern. A large number of small blocks are attached on the upper surface of the pedestal in a one-to-one correspondence via flexible connecting members made of synthetic resin netting to form a floor base layer for supporting the interior furnishings. The small blocks forming the stratum and the pedestals forming the lower base layer are connected by the flexible connecting member while the small blocks and the pedestals can freely bend in the vertical and horizontal directions. It was done.

Action Due to the above-mentioned flexibility, the floor base material adjusts each of the small block group and the pedestal group vertically and horizontally so that the legs of each pedestal absorb the unevenness of the floor construction surface (for example, the concrete slab surface). The floor base layer can be laid on the pedestal without rattling.

According to the structure of the floor base material, the height of the floor base material is ensured by the raising action of the legs, and the small block attached to the pedestal via the flexible connecting member is heavy. It is possible to select an appropriate material as the floor base material that supports furniture such as objects and a walking load, and thereby it is possible to properly secure the impact strength required as the floor base material.

Example A floor base material 1 comprises a floor base layer 2 which supports the floor material, and a lower support layer 3 which supports the floor base layer 2 on the upper side and is supported on the floor construction surface. The floor base layer 2 is composed of a small rigid block 4, and the lower support layer 3 is composed of a group of pedestals 6 having legs 5. The hard small block 4 is made of a member having a high impact strength such as a metal plate, a ceramic plate, a stone plate, a hard resin plate, and a concrete plate, and has an outer shape of a rectangular plate.
Further, the pedestal 6 has a square shape, and the leg portions 5 are vertically provided from the four corners of the rectangular pedestal 6 so as to support the pedestal 6 at a high position, and the metal plate is formed into a form as shown in FIG. The whole is integrally formed by punching and bending according to the broken line shown by the dotted line.

A cushioning cap 7 is attached to the lower end of the leg portion 5 so as to reduce the impact of furniture such as heavy objects and walking load.

Then, a large number of pedestals 6 having the leg portions 5 are aligned and juxtaposed in a grid pattern to form a lower support layer 3, and a flexible connecting member 8 is attached to the surface of the pedestal 6 group with an adhesive. The floor base layer 2 is formed by pasting and then pasting the small blocks 4 in a grid pattern on the surface of the flexible connecting member 8. The pedestal 6 and the small block 4 are arranged in a one-to-one correspondence with the flexible connecting member 8 interposed therebetween. As the flexible connecting member 8, for example, a synthetic resin net material or a flexible sheet material such as cloth is used.

Thus, the small blocks 4 forming the floor base layer 2 and the pedestals 6 forming the lower support layer 3 are connected to each other via the flexible connecting member 8 and have flexibility. The floor base material 1 is formed.

A large number of the unit floor base materials 1 are laid on the floor construction surface to form a floor base. At this time, the pedestal 6 has a flexibility due to the flexibility.
10, for example, to provide a floor base layer 2 which is steadily installed by means of legs 5 so as to absorb irregularities on the surface of a concrete slab, and which provides a floor base layer 2 free from backlash, and a required floor material 12 on the surface of the floor base layer 2. To build a floor set.

The pedestal 6 forms a closed space that spreads over the entire floor construction surface immediately below the floor base layer 2 while raising the floor base layer 2 consisting of the small blocks 4 to a high position by the legs 5, and wiring or piping space.
Secure 13

When the pedestal 6 and the leg portion 5 are formed by bending a metal plate, an arc-shaped portion is formed in the pedestal corner portion, that is, a curved portion of the leg portion 5, and the arc-shaped portion is formed between the adjacent pedestal 6. Harmful groove in 11
By arranging the small blocks 4 so as to be in close contact with each other, it is possible to effectively prevent the groove 11 from forming a recess on the floor surface.

EFFECTS OF THE INVENTION The above-mentioned floor base material is such that each of the small block group and the pedestal group is arranged in the vertical and horizontal directions so that the legs of the pedestal absorb the irregularities of the floor construction surface (for example, the concrete slab surface) due to the flexibility. It can be oscillated and can be installed stably. Therefore, the floor base layer (small block group) can be laid on the pedestal without rattling and used for floor finishing.

According to the construction of the above-mentioned floor base material, the height required for the whole floor base material is secured by the raising action of the legs, while it is attached to the pedestal through the flexible connecting member made of the synthetic resin net material. The attached small block is made to function as a strength member,
By selecting an appropriate material for the floor underlayer formed by the small blocks, it is possible to properly secure the impact strength required as the floor underlayer material for supporting weight-adjusted products, walking loads, and the like.

In addition to this function and effect, the shock can be mitigated by the buffer caps attached to the lower ends of the legs.

By forming a pedestal with legs by punching and bending a metal plate, it is possible to reduce the weight as a whole by the above composite structure with a small block pasted through the mesh material. At the same time, the one-to-one bonding between the metal pedestal and the small blocks can be firmly performed through the mesh of the mesh material, and a floor assembly that is robust against load can be constructed.

In addition, the pedestal with legs raises the entire floor assembly structure to secure piping space, etc., and wiring can be done using the hollow structure inside the floor assembly, but at the time of this wiring work, small block groups and pedestals Since the groups are connected one-to-one by means of mesh members, they are arranged in rows and columns in a grid pattern and are connected to each other, that is, between the blocks and the rows and columns along the four sides around each small block. Since it is possible to form a state in which it is aligned with the vertical and horizontal divisions along the four sides of each of the small blocks through a mesh material, it is necessary to insert a knife into the division along the four sides of each small block during wiring work, but it is invisible from the outside. Instead, it is possible to cut the net material in the section along the four sides around each pedestal, which makes it extremely easy to remove each small block and each pedestal integrally in its vertical row or horizontal row to form vertical and horizontal wiring grooves. Can be done.

After the wiring work, the small blocks in the vertical and horizontal rows and the pedestal that have been removed can be returned to the original state and easily restored to cover the wiring groove.
