Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention is applicable to intelligent buildings, etc., where it is particularly required to freely wire power, communication, and transmission cables for OA equipment and telephones, for example. This paper relates to the improvement of floor structures in buildings.

(Prior Art) This type of conventional floor structure is intended to construct the floor of an intelligent building using a unit floor member 1 as shown in FIG. 3A, and the unit floor member 1 is not finished. It consists of a flooring material 2 and four legs 3 with adjusters 4 installed vertically on the underside of the flooring material 2. When actually constructing the floor of an intelligent building, as shown in FIG. By sequentially laying a large number of unit floor members 1 front to back and left and right on the five slab floors of an intelligent building, a floor is constructed using the flooring material 2 of each unit flooring member 1, while each of the flooring materials By using a space 6 that is continuously defined in the front and rear, right and left directions between the floor space 2 and the five slab floors, it is possible to freely route cables and the like for OA equipment.

(Problem to be Solved by the Invention) It is extremely common for the five slab floors of intelligent buildings to have a rough surface.

The above unit floor member 1 is placed on the 5 slab floor surfaces exhibiting such a rough surface.
When laying the unit flooring 1, it cannot be denied that the position of the flooring 2 of the unit flooring 1 will also be affected by the rough surface and will have some variation in height.

For this reason, the conventional floor structure adopts a configuration in which an adjuster 4 is attached to each leg member 3 of the unit floor member 1 to adjust such height variations, as described above.

However, in a conventional floor structure, when adjusting the height variations caused by the rough surface of the slab floor 5 using the adjuster 4, all the unit floor members 1 must be adjusted to the slab floor 5.
After it is laid on a surface, it must be lifted by the suction means of the corresponding unit floor member 1 and each adjuster 4 must be adjusted individually to obtain the horizontal level of the flooring 2 of each unit floor member 1. A major problem was that the height adjustment work was extremely difficult.

Moreover, such height adjustment work cannot always be solved immediately by adjusting the adjuster 4 once, but usually requires adjustment several times, which makes the height adjustment work even more complicated. It was encouraged.

In addition, in the conventional floor structure, since the adjusters 4 are only provided on the leg members 3 of the unit floor member 1, it is not possible to expect an elastic effect from the method itself. It was wanted.

(Means for Solving the Problems) The present invention was developed to effectively solve the problems of conventional floor structures, and is a method for installing a plurality of joists on the slab floor of a building. A floor structure in which unit flooring materials are arranged at predetermined intervals and are successively placed between the upper surfaces of each adjacent joist material, comprising a holder for holding the joist materials,
The holding body consists of a screw member installed on the slab floor surface via an elastic material, and a receiving member that is screwed into the screw member to hold the joist, and the upper side of the screw member is attached to the joist. The structure is such that it can be inserted rotatably into a mounting hole drilled in the.

(Function) Therefore, in the present invention, first, a state in which the joist is held by the receiving member of the holder is obtained, and the screw member side of the holder is installed on the slab floor surface via the elastic material. After arranging each joist at a certain interval, unit flooring can be placed between the upper surfaces of each adjacent joist, thereby making it possible to immediately construct the floor of the building. However, if there are variations in the height of the top surface of each joist depending on the roughness of the slab floor surface, please insert it into the mounting hole of the joist before placing the unit flooring. By rotating the upper part of the threaded member and moving the receiving member screwed into the threaded member up and down, the height of the top surface of the joist can be easily adjusted accordingly. Become.

Therefore, after that, if you successively place the unit flooring between the upper surfaces of each joist that has been leveled, the horizontal level of each unit flooring itself will be automatically guaranteed, so you can work easily. It is extremely convenient.

(Example) Hereinafter, the present invention will be described in detail based on an example illustrating the present invention.
As shown in FIG. 1, the floor structure according to this embodiment is such that long joists 11 having concave penetrating portions 11a are arranged at predetermined intervals on the slab floor surface of an intelligent building. By sequentially and continuously placing unit flooring materials 12 between the upper surfaces of adjacent joists 11, a continuous space for wiring and piping is defined between the lower surface of each unit flooring material 12 and the slab floor surface. However, the feature is that the joist material 11 is placed on the slab floor surface via the holder 13 described below.

To explain this specifically, the holder 13 is made up of two parts: a screw member 13A and a receiving member 13B. It is configured to be inserted into a mounting hole 19 drilled in the slab 11, and an elastic material 15 such as rubber is provided on the lower end flange 14, and the slab is directly installed on the floor surface of the slab via the elastic material 15. The latter receiving member 13B
The screw member 13A is attached to the bottom of its U-shaped base.
The insertion hole 17 is formed through which the insertion hole 17 is inserted.
A nut portion 18 is integrally provided on the lower edge of the.

It is configured so that it can hold the joist material 11 with its own U-shaped base while being screwed into the screw member 13A.

Further, in this embodiment, as shown in the figure, the screw member 13
A locking groove 16 for locking a tool such as a screwdriver is provided at the upper end of A, and an enlarged diameter portion 19a is formed at the upper opening edge of the mounting hole 19 of the joist 11. A configuration is adopted in which a tool is inserted into the housing and the screw member 13A is rotated by operating the tool, thereby moving the receiving member 13B screwed into the screw member 13A up and down.

Therefore, when installing the joists 11 on the slab floor 20 using the holder 13 having such a configuration, the screw members 13A are inserted into each mounting hole 19 of the joists 11 as shown in FIG. If the upper side is inserted, each long joist 11 is held via a plurality of receiving members 13B, and each screw member 13A is installed directly on the slab floor 20 surface, each joist 11 is They are placed on the slab floor 20 at predetermined intervals.

In such an arrangement state, if there is variation in the height of the top surface of each joist 11 depending on the roughness of the slab floor 20, before placing the unit flooring 12, By locking the tip of the tool in the locking groove 16 of each screw member 13A inserted into the mounting hole 19 of the joist material 11 and rotating the screw member 13A in a predetermined direction, the screw member 13A is rotated in a predetermined direction. The receiving member 13B screwed into the receiving member 13A moves up and down, so that the height of the upper surface of the joist 11 can be easily adjusted.

Therefore, after that, if the unit flooring material 12 is placed between the upper surfaces of the horizontally leveled joists 11, the horizontal level of each unit flooring material 12 will be automatically guaranteed, making the work much easier. It's convenient.

Further, in this embodiment, the screw member 13A of the holding body 13
is installed on the slab floor 20 surface through the elastic material 15, so the presence of the elastic material 15 makes it difficult for each unit floor material 1
2 will be elastically supported, so it will also be possible to provide a floor that can be expected to have an elastic effect.

Therefore, in the end, the unit floor material 12 and the slab floor 20
Since a space S for wiring and piping is continuously defined between the front and rear, left and right sides of the plane, it is possible to use the space S to freely route cables, etc. of OA equipment. In addition, even if rewiring is required due to the addition of OA equipment or a change in the installation location, the unit flooring 12 in the necessary locations can be removed using a known suction method or the like.
By simply removing it from the top surface, cables, etc. can be re-wired extremely flexibly and easily without any modification work.

(Effects of the Invention) As described above, according to the floor structure according to the present invention, a plurality of joists are arranged at predetermined intervals on the slab floor surface of a building,
The joists are arranged on the slab floor surface via a holder, assuming a floor structure in which unit flooring materials are successively placed between the upper surfaces of the adjacent joists. Therefore, the joists are held by the receiving members of the holding body, and the screw members of the holding members are installed on the slab floor surface through the elastic material, and the joists are placed at regular intervals. After installation, if unit flooring is placed between the upper surfaces of the adjacent joists, it becomes possible to immediately construct a floor that can be expected to have a sufficient elastic effect for the building.

In addition, if there are variations in height of the top surface of each joist depending on the roughness of the slab floor surface, it is necessary to insert the floor joists into the mounting holes of the joists before placing the unit flooring. By rotating the screw member attached to the screw member and moving the receiving member screwed into the screw member up and down, the height position of the upper surface of the joist material can be easily adjusted accordingly. Compared to this, the work is much simpler.
