An underground rectangular section tunnel structure formwork construction device

Abstract

The invention relates to a underground rectangular section tunnel structure formwork construction device. The device comprises a load platform and a health support frame, the load platform is in a long strip shape, pulleys are mounted on both ends of the lower side, the inner sides of push and pull handles of the two ends of the upper side of the load platform are provided with positioning fixingframes, the lower ends of the positioning fixing frames are rotatably connected with loading platform frames through steel shafts, the upper ends of the positioning fixing frames are rotatably provided with template fixing devices, the health supporting frame comprises an upper jack tube axially connected to a lower support tube on the upper and lower portions, a spiral turntable is arranged between the upper jack tube and the lower support tube, the upper and lower ends of the health support frame are respectively provided with squeeze support plates, the upper jack tube and the lower supporttube are all provided with rotary pressure rollers, the rotary pressure rollers adopt steel plates for manufacturing to form a semi-circular shape, the straight side is provided with an eccentric circular bushing, and the eccentric circular bushing sleeves the upper jack tube or the lower support tube. The device is reasonable in structure design, is convenient to use, conveniently transport thetemplate dismantled, facilitates compaction of a plastic film in the later stage, and greatly improves the construction efficiency.

Description

technical field [0001] The invention relates to the field of frame structure construction in construction engineering, in particular to a formwork construction device for an underground rectangular section tunnel structure. Background technique [0002] With the upgrading of municipal construction this year, the number of underground pipe gallery projects continues to increase. Generally, traditional construction methods are used to carry out formwork construction. For example, combined formwork is used to install block by block, and the poured concrete reaches strength and then removed block by block. Repeated labor construction efficiency not tall. At present, combined plastic formwork is used in construction, which is characterized by high strength and rigidity and light weight after combination. Therefore, it is suitable to remove the combined larger formwork and transport it to the target area for direct installation. For this reason, it is necessary to develop an under...
