Embodiment Construction

[0026] Rigid column steel frame cylindrical steel formwork structure includes semicircular steel formwork, said semicircular steel formwork is designed as two pieces of splicing, assembled into a cylindrical structure; the cylindrical structures of different sections are hoisted and spliced ​​in sequence along the direction of the busbar to form The entire cylindrical formwork. The semi-circular steel formwork is provided with lifting rings 1, bolt holes 2 are provided at the corresponding positions of the upper and lower frames and side frames, and the side frames are provided with sub-female interfaces (not marked in the figure).

[0027] The reverse order installation and disassembly construction method steps of the rigid column steel frame cylindrical steel formwork provided by the present invention are as follows:

[0028] Step 1: Use the bolt hole 2 of the steel frame at the bottom of the semicircular steel form to install the universal wheel (not marked in the figure), ...

Abstract

The invention discloses a stiff column steel frame cylinder steel template and a reversed-order installation and removal construction method. The stiff column steel frame cylinder steel template is of a structure of a segmental semicircular steel template which is assembled into a segment of cylinder structure. Different segments of cylinder structures are lifted and assembled sequentially in the generatrix direction to form the whole cylinder template. The construction method comprises the following steps that (1) universal wheels are installed on the semicircular steel templates, and the semicircular steel templates are moves to the corresponding positions; (2) two semicircular steel templates are assembled and lifted and pulled to a certain height through an electric block; (3) the step (1) is repeated, the pulled steel template descends and is connected with the next segment of steel template, and then the two steel templates are lifted; (4) the step (3) is repeated until installation of the steel template is completed; and (5) during template removal, the steel template is placed to the ground from top to bottom in a lifted mode through the electric block until work is completed.

Description

technical field [0001] The present invention mainly relates to the formwork construction in building construction, and specifically relates to the construction of the profiled steel structure first, then the outsourcing concrete construction, and the rigid column steel frame cylindrical steel formwork in super high-rise buildings where the tower crane cannot be used to cooperate with the formwork (the upper and lower floors have been closed). Installation and dismantling construction methods. Background technique [0002] A large number of super high-rise buildings use steel-concrete composite structures, especially the concrete core tube and peripheral steel frame structure system. In order to balance the force and appearance, many steel frames use stiff concrete columns. The traditional cylindrical formwork adopts flexible glass fiber reinforced plastics, wood formwork system and small steel formwork, which has many defects such as many seams, poor rigidity and low turnove...
