Membrane frame for constructing lower spherical segment of swivel bridge rotary table and construction method

Abstract

The invention provides a membrane frame for constructing a lower spherical segment of a swivel bridge rotary table and a construction method, which is used for solving the difficulty in the swivel body construction that a template is poor in strength, likely to deform and difficult to disassemble. The membrane frame consists of a main ring body, a quasi ring body, a first supporting body, a second supporting body, a bottom cushion layer, a top first cover layer, a top second cover layer, a first filling member and a second filling member. The construction method comprises six steps of building the main ring body, laying a plastic film, embedding an annular foam plate and a radial foam plate, filling medium coarse sand, forming the top first cover layer in a folding way, and smearing sand pulp on the surface. The memberane frame and the construction method have the beneficial effects that the construction cost is low, the production is simple, the deformation is unlikely to occur, the stability is high, the construction precision of the upper building at a later period can be guaranteed, and the later maintenance work 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...
