Abstract

Aiming at the problems of poor strength, easy deformation and difficult disassembly of the formwork in the construction of the swivel body, the present invention provides a membrane frame for the construction of the ball under the turntable of the swivel bridge and its construction method: the membrane frame described in the present invention A frame consisting of a main torus, a quasi-torus, a first support, a second support, a bottom cushion, a top first covering, a top second covering, a first filler, and a second filler; The construction method of the present invention includes building the main ring body, laying plastic film, pre-embedding the annular foam board and radial foam board, filling medium-coarse sand, turning over to form the first covering layer on the top, and applying mortar to plaster the surface 6 steps. Beneficial technical effects: the present invention has the advantages of low construction cost, simple manufacture, not easily deformed, strong stability, and ensures the precision of superstructure construction in the later stage. In addition, the post-maintenance work of the present invention is simple.

Description

technical field [0001] The invention belongs to the field of construction equipment, in particular to the technical field of formwork support for the junction of the lower turntable of the swivel structure part of the swivel bridge and the lower spherical section of the turntable, and in particular to a tire used for the construction of the lower spherical section of the turntable of the swivel bridge. Membrane frame and construction method thereof. Background technique [0002] In the construction of the swivel structure, after the installation of the spherical joint of the lower turntable is completed, the formwork (also called formwork support) needs to be carried out first, and then the construction of the upper turntable is carried out. This formwork project is an important connecting project between the previous and the next. The safe and reliable formwork project can ensure the smooth construction of the structure of the lower ball section of the swivel body, and ensu...
