Abstract

PURPOSE:To form a stabilized flooring material and, at the same time, to secure wiring and piping spaces therewith by placing unitized flooring materials composed of finishing materials and supporting materials that are laminated together over a floor of an intelligent building or the like through floor joists with movement-preventing means provided thereon. CONSTITUTION:An unitized flooring material 1 is made by laminating a finishing material 2 over a supporting material 3. To the underside of the opposite sides of each of the unitized flooring materials 1, recessed parts 6 are continuously formed. Then, to the surface in the longitudinal direction of a floor joist 4, protrusions 5 and 5 are formed continuously in two stripes as a means of preventing movement. After placing a plurality of floor joists 4 over a slab floor at specified intervals, side edge of each of the unitized flooring materials 1 is placed continuously one after another over a half of the upper face of each of the adjoining floor joists 4 with each of the protrusions 5 and the recessed parts 6 engaged each other. Thereby the unitized flooring material 1 having high resistivity against load and high stability against backlash can be made.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is applied to buildings such as intelligent buildings that require flexible wiring for power, communication, and power transmission cables for OA equipment and telephones, for example. The purpose is to improve the floor structure so that its flexibility can be ensured.

(Prior Art) The present applicant has already provided a floor structure for such an intelligent building as disclosed in Japanese Patent Application No. 193332/1983.

Although not shown in detail, the floor structure consists of a plurality of long joists arranged at predetermined intervals on the slab floor of an intelligent building, and a unit placed on the top surface of each adjacent joist. The floor of an intelligent building is constructed by placing flooring materials one after another.

Therefore, a space for wiring and piping that is continuous in the front and back direction is defined between each adjacent joist, and in the conventional floor structure, each joist has a plurality of concave through holes. Therefore, the above-mentioned space is continuously defined in the left and right direction via each circular penetrating portion.

Therefore, when wiring cables, etc. for OA equipment to such a floor, flexible wiring is fully possible by using the space that is continuously defined in the front-back and left-right directions. At the same time, due to the addition of OA equipment and changes in the installation location,
If rewiring is necessary, remove the necessary unit flooring from the top surface of the floor joists using known suction means, and the continuous space will be easily evaporated. By rewiring the cape, etc. using this, it becomes possible to respond extremely flexibly and easily to the addition of OA equipment or changes in the installation location without any modification work.

(Problem to be Solved by the Invention) However, in conventional floor structures, the unit flooring material placed on the top surface of the joists is formed using only a finishing material, so it naturally has poor load bearing capacity. Inferior, after short-term use,
There was a major problem in that each unit floor material was curved and deformed into a wave shape.

In addition, since each unit flooring material is simply placed and supported between the upper surfaces of adjacent flooring materials, there is ample risk of it moving or rattling inadvertently if unexpected external forces are applied. had it.

(Means for Solving the Problems) Therefore, the present invention was developed to effectively solve the problems of the conventional structure. By placing the unit flooring material on the top surface of each adjacent joist one after another, a space for wiring and piping can be created continuously between the unit flooring material and the floor surface of the building. In the floor structure defined by the unit flooring material, the unit flooring material is composed of a laminate of a finishing material and a supporting material, and movement prevention means that can be locked to each other are provided on the lower surface of the unit flooring material and the upper surface of the joists, respectively. A configuration was adopted to form the structure.

(Function) Accordingly, in the present invention, the unit flooring material is composed of a laminate of the finishing material and the supporting material, and is sufficiently reinforced by the presence of the supporting material, so that the unit flooring material has an outstanding load capacity. It is highly flexible, and there is no need to worry about it bending or deforming even after long-term use, and the unit flooring placed on top of adjacent joists can be moved by locking each other with their respective movement prevention means. Since the unit flooring is always supported in a stable state on the upper surface of the floor joists, there is no need to worry about the unit flooring moving or rattling inadvertently, as was the case in the past.

(Example) Hereinafter, the present invention will be described in detail based on an example illustrating the present invention.
The floor structure according to this embodiment also includes a plurality of long joists arranged at predetermined intervals on the slab floor surface of an intelligent building, and unit flooring material is sequentially placed on the top surface of each adjacent joist. By placing the units in succession, it is assumed that a continuous space for wiring and piping will be defined between the bottom surface of each unit floor material and the slab floor surface.

In this embodiment, as shown in FIG. 1, the unit flooring material 1 is combined with a finishing material 2 made of wood, stone, tile, or other materials, and a finishing material 2 made of concrete, hard resin, etc. It is composed of a laminate of support materials 3 made of metal materials, wood, grating materials, etc., and two convex portions 5, 5 serving as movement prevention means are continuously formed on the upper surface in the longitudinal direction of each of the joists 4. , each unit has a structure in which a concave portion 6 for locking one of the convex portions 5 is continuously formed on the lower surface of the corresponding end of the flooring material 1.

Therefore, when constructing the floor of an intelligent building using the unit floor material 1 and joist material 4 having such a configuration, the second
As shown in the figure, after arranging a plurality of joists 4 at predetermined intervals on the slab floor 7 of an intelligent building, the convex portions 5 and concave portions 6 are interlocked, and each adjacent By simply placing the edge of each unit flooring material 1 in succession on the upper half of the joist material 4, it becomes possible to construct the floor of an intelligent building extremely easily.

Moreover, in such a construction state, as mentioned above, each unit flooring material 1 is composed of a laminate of the finishing material 2 and the supporting material 3, and is sufficiently reinforced by the presence of the supporting material 3. , the unit flooring material 1 has excellent load-bearing properties, and even after long-term use, there is no need to worry about it curving or deforming into a wave shape like in the past. Due to the mutual locking of the convex part 5 and the concave part 6,
Since it is always supported in a stable state, even if an unexpected external force is applied, there is no need to worry about the unit flooring 1 itself moving inadvertently or rattling, unlike in the past. .

Further, in the above embodiment, as a movement prevention means, a convex portion 5 is formed in succession on the joist 4 side and a concave portion 6 is continuously formed on the unit floor material 1 side, but the present invention is not limited to this. Of course, it is not only possible to form both parts 5 and 6 intermittently in the longitudinal direction of each village 1 and 4, but also, for example, as shown in FIG. On the top surface of the joist material 4,
Convex portions 5 or concave portions 6 are intermittently formed in a state perpendicular to the longitudinal direction, and concave portions 6 or convex portions 5 are interlocked with the convex portions 5 or concave portions 6 on the lower surface of the unit flooring 1 on the edge side. It is also optional for the implementation to form a lock or use other locking means as appropriate.

In addition, even in the floor structure of this embodiment, since a plurality of concave penetrating portions 4a are formed in each joist material 4, the space S defined between the unit floor material 1 and the slab floor 7 is Since it will be continuous in the front-rear direction and left-right direction, using the space S,
In addition to making it possible to freely route the cables, etc. of OA equipment, even if rewiring is required due to the addition of OA equipment or a change in the installation location, the unit flooring 1 can be installed in the necessary locations. Cables, etc. can be re-routed by simply removing them from the top surface of the joists 4 using known suction means, etc.
Needless to say, it can be adapted very flexibly and easily without any modification work.

(Effects of the Invention) As described above, according to the floor structure according to the present invention, the unit flooring is composed of a laminate of the finishing material and the supporting material, and is sufficiently reinforced by the presence of the supporting material. The unit flooring material has excellent load resistance, and there is no need to worry about it bending or deforming even after long-term use, and the unit flooring material placed on top of the adjacent joists has its own movement prevention. Since the means are mutually locked and always supported in a stable state on the upper surface of the floor joists, there is no need to worry about the unit flooring moving or rattling inadvertently as in the past.
