Technical Field

The present invention supports the upper panel of the access floor installed in the office where computers, monitors, fax machines, copiers, etc. are frequently used such as computer room, traffic control room, etc. It relates to a support structure.

Prior art

An access floor is a compound word of access (ACCESS), computer terminology for putting information in or out of a computer system, and a floor (floor). Therefore, it is also referred to as raised floor, double floor or O / A floor.

In other words, the access floor refers to the raised floor that is proposed to secure a more comfortable and efficient office space in the information age, when the use of computers is increased.

In ordinary buildings that were not constructed as access floors in the past, small molds have been used to protect telephones or electric lines. However, this approach was limited, and with the rapid increase in the use of computers, offices became more confused with cables, raising the need for new floor structures.

The access floor means to make one more floor by placing a space of a certain height on the flat floor to solve the above problems. And it arranges a cable in the space and forms the structure which can open and close a floor as needed for cable relocation.

Installation of access floor is as follows.

-Computer room (public offices, companies)

-Telephone exchange room (telephone station)

Clean room of semiconductor plant

-Chemistry Lab (Air Purification)

-Sound control room (recording room, studio cable protection, dustproof, soundproof)

-Lecture room (computer education, audiovisual education)

-Conference room (video conference room, conference room with a lot of sound equipment)

-Offices (public offices and corporations that use a lot of computers)

-Other high-tech equipment factory (dust, bacteria occurrence suppression)

The types of access floors are classified into steel wood composite type, wood type, iron type, aluminum type, etc. according to the material of the panel.

1) Wood Core Panel

The wood type not only maintains the unique sensation of walking, but also has excellent sound absorption, which reduces vibration and noise. It is widely used in broadcasting rooms, lecture rooms, meeting rooms, offices, laboratories, telephone exchange rooms, business centers of financial and public institutions, computer rooms, communication machine rooms, and control rooms. Recently, in order to eliminate the risk of fire, a high density particle board is adopted.

2) Steel Panel

The upper and lower panels are made of steel, and the lower panel is of dynamic structure. As it has excellent load resistance, durability, robustness, safety and fire resistance, it is mainly used for central control panel (MDF) room, machine room, and control room. In some cases, steel cement panels filled with concrete between upper and lower steel sheets may be used to compensate for the shortcomings of the steel panel and to increase the effect of dustproof and soundproofing and to prevent deformation.

3) Aluminum Panel

Aluminum type is a panel made of high purity aluminum alloy, which is a lightweight panel with excellent corrosion resistance and durability. In particular, it is mainly used in semiconductor factories, precision measuring equipment rooms, optical equipment rooms, clock assembly rooms, electronic equipment rooms, etc., which require sterility and electrostatic conductivity and precision.

4) Composite (Steel & Wood)

The access floor was developed to make up for the shortcomings of the wood type and steel type and to make the best use of its advantages. Compared with general wood type, it has excellent loadability (more than 30%) and is widely used in MDF room, machine room, electronic exchange room, computer room (school, enterprise, public institution), and business place.

The conventional installation of access floor is to make a double floor with the feet on the square plate that is about 50cm wide by making the space about 30 ~ 40cm from the floor and installing the data line in the space under this access floor. .

However, in the conventional access floor, several supporters are installed at the installation site and fixed, and the upper panel is mounted thereon. In this case, the access floor using the supporters individually fixed has the following problems.

Firstly, each support is not connected but is supported independently. If a part of the supports is broken, it is a structural weakness, causing local collapse and eventually risking collapse of the entire access floor.

Second, because of being fixed alone, the support force for the horizontal shear force of the support is weak.

Third, the support force for the compressive force in the vertical direction of the support is also weak.

That is, the conduction pattern when the shear force (earthquake force) is applied horizontally to the conventional access floor is as follows. Conventional access floors are generally configured in such a way that the top panel is placed on a single support. This method is weak to the horizontal shear force acting on the support as described above. Therefore, when a horizontal force is generated inside the building and sheared to the access floor, the upper panel of the access floor is pushed to the side, and the support that does not endure the shear force collapses, resulting in the collapse of the access floor structure because the upper panel is removed from the support. . For this reason, the conventional access floor is likely to be defective before and after construction, and sometimes occurs. In addition, even if excessive loads are generated locally on the access floor, local settlement may occur because of the limitation of the supporting capacity of the supporting members individually.

As such, the conventional access floor is particularly vulnerable to a horizontal shear force generated by an earthquake or the like, and has a structural problem that cannot be effectively sustained even in the vertical compressive force.

The purpose of the present invention created to solve the problems of the conventional access floor support structure as described above is as follows.

First, an object of the present invention is to provide an access floor support structure equipped with seismic performance.

Secondly, another object of the present invention is to provide an access floor support structure that is easily adjustable in height.

Third, another object of the present invention is to provide an access floor support structure that can shorten the air by easy installation and release work.

The composition of the present invention created to achieve the above object is as follows.

The present invention is a structure for supporting the upper panel of the access floor to form a double bottom on the top of the bottom slab, the vertical support provided with a thread; An upper connection piece fastened to the vertical support and movable up and down; A lower connection piece fastened to the vertical support and movable up and down and spaced apart from the upper connection piece; A horizontal reinforcing support having one end coupled to the upper connection piece and the other end coupled to the upper connection piece fastened to an adjacent vertical support; And an inclined reinforcing supporter having one end coupled to the lower connection piece and the other end being coupled to a horizontal reinforcing supporter.

Hereinafter, with reference to the accompanying drawings, a specific embodiment of the present invention will be described in detail.
