Easy-to-disassembling support structure

The utility model relates to an easy to disassembling support structure, belonging to the working jumbo for tunnel lining support technique. The structure mainly consists of a steel cylinder and two support bars at the two ends of the steel cylinder; wherein the steel cylinder is divided into two chambers by a clapboard; one end of the steel cylinder is connected to the worm of the connecting support bar and form a screw pair; one end of the connecting support bar is a guide sleeve which is positioned in the steel cylinder and clearance fits the inner wall of the steel cylinder; and the inner capacity where the guide sleeve is filled with granule solid(such as sand). The utility model utilizes the uncondensibility of the granule in the seal space to bear axial force; when unload a module, just take out parts of the granules, the screw pair formed by guide screw and a nut changes into an unloading situation from a full load situation, so as to achieve convenient use and efficacy improvement aim. The design of the utility model is simple and reasonable in structure, thus can effectively solve the problem that the side support between the trolley bracket and the module is uneasy to be unloaded after being fastened.
