Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments.

The utility model provides a composite supporting structure as shown in figures 1-3, which comprises two retaining plates 1 arranged on two side walls in a foundation pit, wherein the two retaining plates 1 are arranged in a central symmetry manner, two ends of each retaining plate 1 are fixedly connected with supporting plates 8, two sides of opposite ends of each retaining plate 1 are fixedly connected with connecting pieces 2, each connecting piece 2 is movably connected with a bracket 3 through a pin shaft, threads are formed on the outer sides of the corresponding screws 4, threaded holes 7 matched with the threads on the outer sides of the corresponding screws 4 are formed on one ends of the corresponding brackets 3, the number of the brackets 3 is two, the brackets 3 are concave, the inner walls of the corresponding brackets 3 are movably connected with the corresponding screws 4, one end of each screw 4 is fixedly connected with a hand wheel 5, the other end of each retaining plate 1 is fixedly connected with a bolt cylinder 6, and the inner walls of the corresponding bolt cylinders 6 are provided with internal threads and are matched with the corresponding screws 4.

In the installation process, the screw rod 4 is rotatably inserted into the inner wall of the threaded hole 7, then the hand wheel 5 is rotated, the screw rod 4 is driven to rotate by rotating the hand wheel 5, meanwhile, the bracket 3 is rotated to enable the center line of the screw rod 4 to be in line with the center line of the bolt cylinder 6 arranged on the other retaining plate 1, the hand wheel 5 is continuously rotated to connect the screw rod 4 with the bolt cylinder 6, and accordingly the fixation between the two retaining plates 1 is completed through the cooperation of the connecting piece 2, the bracket 3, the screw rod 4 and the bolt cylinder 6.

The device is in the installation, only need through rotating hand wheel 5 and support 3, can accomplish the fixed between two retaining plates 1, when having guaranteed supporting construction's overall stability, reduced part quantity and installation step, greatly improved the installation convenience of device.
