Description

Bridge structure of raised floor Technical Field The utility model belongs to the technical field of floors, and particularly relates to a bridge structure of an overhead floor. Background The raised floor is called as a dissipative type electrostatic floor, and is mainly formed by combining and assembling adjustable brackets, cross beams, panels and the like. Raised floors are often laid in factories that are more critical to the processing environment, and typically the adjustable brackets of the raised floors are placed at the four corners of the panels. However, in practice, various pipes, lines, etc. are usually provided at the lower part of the raised floor in the factory, so that the adjustable bracket cannot be installed in a partial area where the pipes or lines pass. Disclosure of utility model The present utility model aims to solve at least one of the technical problems existing in the prior art. Therefore, the utility model provides the bridge structure of the raised floor, which has the advantage of effectively supporting the floor while avoiding pipelines or lines when laying the floor. The bridge crossing structure of the overhead floor comprises a plurality of main supports, wherein the main supports are vertically fixed on the ground, channel steel is arranged above the two main supports when the distance between the two adjacent main supports is larger than the width of the floor, a plurality of cross beams are arranged above the channel steel, the cross beams are sequentially connected end to end along the straight line direction of the channel steel, mounting pieces are arranged between the two adjacent cross beams, the mounting pieces are fixed on the channel steel, edges of the floor fall on the cross beams, and corners of the floor fall on the main supports or on the mounting pieces. According to one embodiment of the utility model, the device further comprises an auxiliary bracket, wherein the auxiliary bracket is vertically fixed on the ground, the upper end of the auxiliary bracket supports the channel steel, and the auxiliary bracket is positioned at the middle part of the cross beam. According to one embodiment of the utility model, the mounting piece comprises a screw rod and a supporting block arranged above the screw rod, the lower end of the screw rod penetrates through a mounting hole in the channel steel and is fixed on the channel steel through a nut, and the supporting block is connected with the cross beam. According to one embodiment of the present utility model, the length of the channel steel is m millimeters, the width of the floor is n millimeters, and m=n×x+100, where x is an integer greater than or equal to 2. According to one embodiment of the utility model, the lower ends of the main bracket and the auxiliary bracket are fixed on the ground through expansion screws. The bridge structure has the beneficial effects that the bridge structure is mainly used in the situation that the main support for supporting the corners of the floor cannot be installed when pipelines and lines are paved below the floor, the channel steel is erected between the two main supports at a far distance, and the cross beam and the floor are supported by matching with the installation piece, so that the pipelines and the lines can pass below the channel steel, and meanwhile, the supporting performance of the floor can be ensured. Meanwhile, an auxiliary support can be arranged below the channel steel, the pipeline and the circuit are avoided, the middle part of the channel steel is supported upwards, the channel steel is prevented from bending and deforming downwards, and accordingly the supporting strength of the floor is further improved. Additional features and advantages of the utility model will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the utility model. The objectives and other advantages of the utility model will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings. In order to make the above objects, features and advantages of the present utility model more comprehensible, preferred embodiments accompanied with figures are described in detail below.
