Antique building steel cap block, bracket arm and center block combined structure mounting and construction method

Abstract

The invention discloses an antique building steel cap block, bracket arm and center block combined structure mounting and construction method. The method comprises the following steps that 1, components are decomposed; 2, the components are cut and discharged; 3, combination and welding are carried out to form prefabricated steel cap block and bracket arm basic components and pre-assembly components; 4, welding seams are ground; 5, trial splicing of medium independent steel components is carried out; 6, the steel components are subjected to rust removal, corrosion prevention, paint treatment and numbering; and 7, the medium independent steel components are installed on site. The components are decomposed through a BIM technology, a plane detail drawing of each component is drawn by using AutoCAD, the small steel components are spliced, combined, welded and constructed in advance in a factory by using the steel components prefabricated in the factory, the number of the components directly installed on site is reduced, a cap block, bracket arm and center block combined structure is directly installed on an antique building construction site from top to bottom, the installing space issufficient, the field operation workload and construction difficulty are reduced, the working efficiency is improved, and the investment cost is reduced while the project quality is ensured.

Description

technical field [0001] The invention belongs to the technical field of installation of a bucket arch rising composite structure, and in particular relates to an installation and construction method of an antique architectural steel bucket arch rising composite structure. Background technique [0002] Buckets, arches, and lifts are used in ancient wooden structures as force-transmitting components in the building. The load transmitted from the superstructure is transmitted to the columns through the bucket arches, and then to the foundation. Therefore, the bucket arch plays the role of connecting the upper and lower to transfer the load. In modern antique buildings, concrete structures are mostly used for the main structure at this stage, and concrete solid web members are also used for bucket arches and other components. And many other factors, processing and maintenance occupy space. At the same time, due to the small cross-sectional size of the upgraded components and th...

Problems solved by technology

In modern antique buildings, concrete structures are mostly used for the main structure at this stage, and concrete solid web members are also used for bucket arches and other components. and many other factors, processing and maintenance occupy space

At the same time, due to the small cross-sectional size of the upgraded components and the large number of identical components, the installation position of the rack is not easy to control, and the work efficiency of repeated operations is low.

In addition, the existing anti-archaism building bucket arch installation procedures mostly use the installation of the bucket arch system between each floor to follow the order of first down and then up. The construction space is getting smaller and smaller, which is not convenient for the installation of the bucket arch system, and the construction is difficult. A slight deviation will lead to failure to meet the expected quality requirements
