BIM-based prefabricated component connection structure and its construction method

Abstract

This application relates to the field of building component technology, in particular to a BIM-based fabricated component connection structure and its construction method, which includes a column and a steel beam fixed at one end to the column, and the column is also provided with a support for the steel beam The corbel, the corbel consists of two support plates arranged horizontally at intervals, a cover plate abutting against both support plates is arranged between the two support plates, and the steel beam includes a web and wings connected to both sides of the web There is a cavity for storing cement slurry in the web, and the cover plate is rotatably connected to a wing plate of the steel beam. There is an arc piece connected to the cover plate at one end on the cover plate, and the free end of the arc piece extends into the In the cavity of the web plate, a through hole for the free end of the circular arc piece to pass through the cavity is provided on the wing plate through which the circular arc piece passes. This scheme can save the operation of formwork and cast-in-place corbels for supporting construction corbels at high altitudes, thereby facilitating the construction of corbels by construction personnel.

Description

technical field [0001] The present application relates to the field of building component technology, in particular to a BIM-based prefabricated component connection structure and its construction method. Background technique [0002] With the advancement of science and technology and the development of the construction industry, prefabricated buildings are being vigorously promoted. BIM is a digital expression of the physical and functional characteristics of a facility. As an advanced information modeling technology, BIM is more and more widely used in the field of building construction in conjunction with assembly. [0003] In a prefabricated component connection structure of a related technology, in order to install the beam made of section steel on the concrete column, on the basis of connecting the end of the steel beam to the column through high-strength bolts, a corbel will be set on the column It is used to support steel beams. Casting corbels and columns together ...

[0003] In a prefabricated component connection structure of a related technology, in order to install the beam made of section steel on the concrete column, on the basis of connecting the end of the steel beam to the column through high-strength bolts, a corbel will be set on the column It is used to support steel beams. Casting corbels and columns together will limit the scope of use of the formwork used. Therefore, many construction sites choose to use cast-in-place construction of corbels. During the process of casting corbels, construction workers are at high altitude The operation of supporting formwork and cast-in-place is extremely inconvenient, so it needs to be improved
