Description

Double floor system {Access floor system}

The present invention relates to a double floor system, and more particularly to a double floor system that can improve the construction speed and increase the load resistance.

In general, a floor of a residential building or an office building is formed by mortar being poured on a concrete slab to form a base surface, and a floor material such as tiles is laid on the base surface. The office equipment and high-tech equipments such as electrical, electronic and computer equipment are placed in various places on the floor. At this time, if the wires for supplying power to these equipment is installed to be exposed to the outside, the interior of the building is not neat and dirty. In addition, there is a problem that the possibility of a safety accident due to the unprotected neglect of the wire and communication line is high. Therefore, in recent years, a double-floor system is provided to form a double floor on the floor of an office building to accommodate devices such as wiring and air conditioning facilities in the space between the panel and the base surface. As a result, the interior aesthetics of the building can be neat and safety accidents can be prevented.

Currently, various forms are disclosed as the double bottom system as described above. Korean Patent Laid-Open Publication No. 2000-0001389 as a conventional double bottom system discloses a double bottom system provided with a plurality of supports, a plurality of rails and a plurality of panels. The Korean Laid-Open Patent discloses a plurality of supports on an upper surface of a base surface, a rail is supported in a continuous beam shape on the plurality of supports, and a plurality of supports are installed side by side at a predetermined interval to correspond to the base surface. A plurality of panels is installed in the. The panel is arranged in parallel with the base surface in a state in which one side is in contact with the adjacent panels to form a double bottom surface. In addition, the support is provided with a support plate, a support shaft, a support and height adjustment. A screw portion is formed on the side wall of the support shaft, and a height adjusting tool corresponding to the support shaft has a short pipe formed to be inserted into the upper side of the support shaft. A predetermined fixing part is installed in the form of a screw on a predetermined portion of the outer circumference of the height adjusting device, and when the fixing device is screwed, the position of the height adjusting device is fixed by pressing the side of the support shaft inserted into the height adjusting device. It was formed to be. In the conventional double-floor system as described above, the height of the height adjusting opening of the support must be adjusted to maintain the level of the construction surface, and the work of fixing the position of the height adjusting opening by applying external force to the fixing unit installed on the side wall. Therefore, there is a problem in that the horizontal adjustment of the panel is not easy, the construction speed is low, and the manufacturing cost of the parts required for the fixing part is increased.

The present invention is to solve the problems as described above, the construction speed is faster than the conventional, the horizontal level of the panel is easier to adjust, strengthening the inter-panel fastening to suppress the impact noise between panels due to play, The aim is to provide a double bottom system that improves load resistance.

The present invention to achieve the object as described above is a plurality of supports installed on the upper surface of the base surface; A plurality of rail supports coupled to each of the plurality of supports to move up and down, and having a groove on which a rail may be seated; A rail firmly fixed to the plurality of rail supports; And a plurality of panels spaced apart from the base surface to form a double bottom with the base surface, wherein the rail includes at least one end portion of the plurality of first panels arranged along a longitudinal direction of the rail; Provided is a double-bottom system characterized in that the end of at least one of the plurality of second panels listed along the longitudinal direction of the rail in contact with the plurality of first panels is firmly seated.

Here, the rail support is preferably provided with a hollow on the lower surface and a screw thread is formed along the outer circumferential surface of the hollow, so that the bolt provided on the support is moved up and down along the screw thread. In this case, it is possible to easily adjust the horizontal level of the panel, it is possible to improve the construction speed.

Here, the rail has a width equal to the width of the rail support groove, it is preferable to be seated and firmly fixed while being fitted to the plurality of rail support groove. In this case, the rail can be stably fixed on the rail support.
