Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a raised floor support structure for an intelligent building that can flexibly respond to the demands of tenants.

[Conventional technology]

○A (office automation) is attracting attention these days, and we need an intelligent system that can flexibly respond to office automation.

Demand for Gient-compatible buildings is increasing.

In the case of an intelligent building, the demands of tenants after completion will vary, so in order to meet those demands, various considerations must be made in various parts of the building.

For example, we install air conditioning equipment such as in-ceiling cable ranks, Nakamoto wiring ducts, floor-mounted electrical outlets, floor-mounted telephone outlets, floor-mounted information outlets, general air conditioning, and ceiling-embedded fan coils. In order to flexibly respond to tenant requests, such as adjusting the ceiling height to accommodate raised floors, all facilities had to be prepared in advance. In particular, intelligent buildings require a greater amount of wiring than ordinary buildings, as various types of information are exchanged between the inside and outside of the building. Furthermore, individual equipment is subject to drastic changes due to technological innovations, and construction work such as expansion and modification is expected, so it is desirable to consider flexible wiring paths for replacement work after completion.

[Problem that the invention seeks to solve]

However, at present, free access construction is a method for constructing wiring paths that requires a large amount of work and is highly flexible, but it has the following problems. The first is the high cost, and the second is that
The floor makes a rattling noise and the stability of the floor is poor, making it easy to get tired and generate noise.

The present invention solves the above problems, and aims to provide a raised floor support structure that reduces noise and improves stability.

Means for Solving Problem c] To this end, the raised floor support structure of the present invention has the following features:
The present invention is characterized in that the cap nut is integrally constructed with the frame, and the floor panel receiver is bolted to the cap nut.

[Effect]

In the free access floor support structure of the present invention, the cap nut is integrated with the frame, so it is highly stable.Furthermore, since the floor panel holder is bolted to the cap nut, the height can be adjusted and there is no backlash. Noise generation can be prevented.

〔Example〕

Examples will be described below with reference to the drawings.

FIG. 1 is a diagram for explaining one embodiment of the raised floor support structure according to the present invention, FIG. 2 is a diagram for explaining another embodiment of the raised floor support structure according to the present invention, and FIG. FIG. 3 is a diagram for explaining the third embodiment of the free access floor support structure according to the present invention, in which 1 is a frame, 2 is a truss bar, 3 is a cap nut, 4 is a floor panel receiver, and 5 is a bay. Section 6 indicates concrete PC.

In the embodiment shown in FIG. 1, a cap nut 3 is attached to the parallel chord truss portion of the truss bar 2 so as to protrude above the frame 1.
A floor panel receiver 4 is bolted to a cap nut 3 protruding from the frame 1 after pouring concrete.

Further, in another embodiment shown in FIG.
The bay part 5 of the truss bar 2 is made to protrude above the frame 1, and the cap nut 3 is attached thereto and the floor panel receiver 4 is tightened with bolts. In this way, the curved portion 5 of the truss bar 2 protrudes above the frame 1, resulting in excellent earthquake resistance.

Furthermore, in the embodiment shown in FIG. 3, a small concrete column is made into a PC, the concrete PC 6 is fixed to the truss reinforcement 2, and concrete is poured and integrated. Or, in the case of the Omnia version, pour thin concrete. Then, after welding the concrete PC6, weld the cap nut 3 and bolt the floor panel receiver 4.

Note that the present invention can be modified in various ways and is not limited to the above embodiments. As mentioned above, the free access floor support structure according to the present invention incorporates the support hardware (cap nuts and floor panel holders), which is the biggest factor in cost increase, into the floor structure and integrates it with the floor structure. This not only reduces costs, but also improves stability through integration with the building frame.

FIG. 4 is a diagram showing an embodiment of an embedded box suitable for guiding cables and piping from the floor surface in combination with the free access floor support structure according to the present invention, where 11 is an embedded box and 12 is an embedded box. Piping space, 13 is power supply space, 14 is communication space, 15 is separator, 16 is drainage hardware, 17 is cock, 18 is drain pipe, 19
is air conditioning piping, 20 is electrical piping, 21 is the finished surface, 22
indicates a concrete floor, and 23 indicates a blind lid.

The embedded box 11 shown in FIG. 4 is divided into piping space 12, power supply space 13, and communication space 14 using a separator 15, and the plan view thereof is shown in FIG. Fig. 4 (bl) is a cross-sectional view showing how it is installed on the concrete floor 22. Air conditioning piping 19 that guides hot and cold water, refrigerant, etc. is laid from the PS (pipe shaft), and is connected to the power supply space 13 and the communication space 1.
4, electrical piping 20 for power supply and communication is laid from an EPS (electric pipe shaft). Further, the embedded box 11 is covered with a blind cover 23, which is removed when the embedded box 11 is used, and the pipes and wiring are extended to a predetermined location. Since the piping and wiring in this case are rolled on the floor, it is suitable to combine with the raised floor support structure according to the present invention.

A plurality of embedded boxes 11 as described above are arranged along the window side, wall side, or at an appropriate position on each floor. In this case, it is preferable to arrange them in correspondence with the smallest partition unit so that, for example, there is always one place in the smallest partition unit when rented out by a tenant.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, the supporting metal parts (bag napfts and floor panel supports), which are the biggest factor in cost increase, are incorporated into the floor structure,
Since it is integrated with the floor structure, it is possible to reduce costs. In addition, the stability of the floor is improved by integrating it with the frame, and the noise generated by floor rattling is suppressed by fixing the floor panel receiver to the cap nut using height-adjustable bolts. can do.
