Description

Double floor structure of building {FULL WIRING FLOOR SYSTEM FOR OFFICE BUILDING}

The present invention relates to a floor structure for wiring construction in the lower space of the office floor, and more specifically, using a structure formed by pouring a fiber-reinforced cement mortar on a floor sheet made of POLYSTROL material Simplify installation and repair work, improve walkability and sound insulation after construction, and systematically form wiring work and wiring management to minimize the cost of change work and difficulty of change work due to office design change. It is about double-floor structure of building.

In addition, it relates to the double-floor structure of the building that anyone can easily check and check the wiring line installed on the floor below.

As is well known, various electronic devices are operated by receiving power through a wire that connects equipment and equipment to each other from a power supply line for receiving power so that all operations can be performed. If you use the electronic equipment as it is on the bottom of the floor, many wires are still exposed on the floor, which gives a visually bad impression, and may cause a short circuit by being pressed by people or other equipment passing by. This created a serious problem that could damage expensive equipment and even cause a fire.

In order to alleviate the above problems, the general office floor structure was used by introducing a construction tech plate construction method and a double floor floor method for OA, as shown in FIGS. 1 and 2.

The construction tech plate construction method will be described with reference to FIG. 1 as follows.

After installing the frame (1) such as H-beams on the floor at regular intervals, and arranged in succession horizontally several sheets of the tech plate (2) on the upper surface of the frame (1), the connected tech plate ( 2) Reinforcement is added to the upper surface of 2), and wiring work including the cover plate 3 and the system box 4, etc. is carried out, and then the concrete 5 is poured to a certain thickness to double-layer structure. Was formed.

Here, the protrusions to which the concrete 5 is not applied, that is, the lower part of the system box 4, remain as spaces.

The cover plate (3) is coupled to the lower part of the floor space and used as a wiring through which various electrical wirings or wires of office automatic electronic devices pass.

Next, referring to FIG. 2, a construction method of a general OA floor is as follows.

With a flat panel 6 made to a certain size and a height-adjustable support 7 attached to each corner of the lower surface of the panel 6 to support the panel 6 spaced apart from the floor 8 of the building. In accordance with the number of floors of the general OA floor floor office configured in this way, the panel (6) in a series of planar combination of several successive planes to form a flat surface.

And thus, the bottom plane formed of a plurality of panels (6) was adjusted to the overall level by adjusting the height adjustment support (7) attached to the lower surface of each panel (6). Further, the wiring was arranged and embedded in the space between the plane formed by the panel 6 and the floor surface 8 of the building.

In this way, the office with the double floor is provided with wiring in the space formed between the upper and lower floors, so that the floor of the room can be neatly arranged, and the wiring is pressed by moving objects such as nearby appliances or people. Fixed short circuit and short circuit caused by jamming or jamming.

However, the double bottom structure as described above has solved all the problems caused by the protruding wiring, but had problems in its own structure and construction.

First, the problems caused by the construction of the concrete deck plate for construction are as follows.

Cover plate to be coupled to the lower portion of the space is mounted by a joining method by welding or riveting, there was a very difficult and time-consuming closure of the work. In addition, wiring of various electric wires or office electric equipments is often changed during construction. In this case, the separation of the cover plate is very difficult, and it is possible to cope with layout change and wiring expansion after installation. There was a problem that was difficult to do.

Second, the problems caused by the double-floor floor construction for OA are as follows.

The floor plane formed of the square panels had to be horizontally adjusted to each square panel according to the floor condition of the building, and thus there were many difficulties in the installation work. In addition, when the person walks after installation, the ringing phenomenon occurs, the walking feeling is not good, and the concentrated panel works at a certain place for a long time, or the square panel of the part where many people repeatedly step on the horizontal level is deteriorated with respect to the entire horizontal plane. The horizontal work had to be repeated.

And since the wiring is made arbitrarily, in case of design change, wiring expansion, wiring repair, and wiring replacement during use, the worker must work on the condition that the panel can be arbitrarily pulled out. There was a lot of trouble.

In conclusion, the common problems caused by the double-floor construction can not be determined visually after the construction of the wiring layout, it is very difficult to work and maintain the additional wiring due to the design change and expansion of the office There was a drawback, and there was also a problem that caused walking feeling and floor ringing due to walking.

Therefore, the present invention was invented to solve the above problems, and is not limited to securing a lower wiring space using a double bottom, so that systematic wiring operation is possible in view of convenience of construction and wiring management and maintenance after construction. In addition, it is possible to facilitate the wiring space according to the design change and increase of the office, thereby improving the overall economical efficiency.

In addition, the purpose is to improve the comfort of the office and work efficiency according to the improvement of walking comfort and floor sound insulation after construction.
