Problems solved by technology

[0002] In recent years, multi-storey public buildings often use steel structure bridges to connect different building structures for people to pass through. If steel structure bridges are installed between new buildings, the bridges can be completed according to the actual construction conditions on site and according to the drawings. Adding connecting bridges between new and old buildings is due to the aging of the existing building structure, especially for the existing buildings with dry-hanging curtain walls on the outer facade, because the internal structure is unpredictable, the installation cannot fully guarantee the structural safety, the risk is greater, and there are many construction difficulties

Embodiment 1

[0041] The construction method of the simply supported transfer beam steel structure connecting bridge of the existing curtain wall building provided by this embodiment includes the following steps:

[0042] (1) Analysis of existing building structure

[0043] Remove the wall and curtain wall of the existing building where the bridge needs to be installed and expose the existing building structure, find out the structural column that can be used as a support, and design a simple structure that can meet the steel structure bridge support according to the actual size and situation of the column. A transfer beam is used to tie the structural column.

[0044] (2) Installation of the existing framed corbel buried board

[0045] 1 Install the embedded slab on the frame column, and the embedded slab adopts chemical planting reinforcement. First, according to the design requirements, determine the position according to the spacing and edge distance of the drawings, and drill holes o...

[0070] (1) Expansion project on the south side of Hall 3# of Qingdao International Convention and Exhibition Center Conference Center Project

[0071] Project Overview

[0072] The expansion project on the south side of Hall 3# of Qingdao International Convention and Exhibition Center Project is located at No. 9 Miaoling Road, Qingdao, with a construction area of ​​12,974㎡ and a hall area of ​​5,386㎡ on the first floor. In order to connect the roof of the building with the original building, a steel structure is required bridge.

[0073] Construction

[0074] A steel structure connecting bridge needs to be installed on the north side of the roof of this project. This process is used to set simply supported transfer beams and tie the frame columns of the original building. The steel structure connecting bridge is connected to the simply supported transfer beams. The installation process of this project is strictly in accordance with The construction method of this constructio...

Abstract

The invention discloses a construction method of a simply-supported transfer beam steel-structure connecting bridge in an existing curtain wall building. The construction method comprises the steps that (1) an existing building structure is analyzed; (2) bracket buried plates are installed on an existing frame column; (3) simply-supported transfer beams are installed; (4) a sliding hinge support of a newly built structure is installed; (5) a steel structure of the connecting bridge is installed; (6) the steel structure is detected; (7) floor slabs of a steel beam frame are installed; (8) concrete is poured; and (9) stone is paved and guard rails are installed. The construction method is standard and systematic, and the simply-supported transfer beams are arranged additionally on the existing curtain wall building, so that the steel-structure connecting bridge is provided with a stable support; and the construction structure of the construction method is stable, the structure of the existing building is strengthened, structural columns of the existing building are tied, and the effect is good.
