Suspension holder construction method

Abstract

The invention relates to a suspension support construction method, wherein it comprises: arranging at least two main beam I-shaped steels for supporting air gallery between two high position of building; fixing several sub beams between nearby I-shaped steels; said I-shaped steels and the sub beams are arranged with lifting rod; the lifting rod and the frame of main building are fixed with steel tube to form suspension support as falsework; with said structure, the I-shaped steels and sub beams support force; and the mould support and falsework are suspended on the I-shaped steels and the sub beams, and connected to the frame of main building, without affecting the construction speed, with stable structure, and reduced cost.

Description

technical field [0001] The invention relates to a construction method of a suspension frame, which belongs to a construction method of a fixed building. Background technique [0002] Aerial corridors are mostly seen between two taller buildings (main buildings), and their structures are mostly cast-in-place reinforced concrete structures. During construction, formwork needs to be laid to pour concrete, and scaffolding needs to be erected for construction. When the corridor (mainly the beam supporting its main body) adopts a pure reinforced concrete structure, because it cannot withstand external forces before solidification, it is even necessary to rely on the reinforcement cage on other structures to ensure its accurate position during construction, and it is necessary to set up a formwork frame and scaffolding; and when the ground height of the aerial corridor is high, the formwork and scaffolding erected are prone to instability, and relevant regulations do not allow this...

[0002] Aerial corridors are mostly seen between two taller buildings (main buildings), and their structures are mostly cast-in-place reinforced concrete structures. During construction, formwork needs to be laid to pour concrete, and scaffolding needs to be erected for construction. When the corridor (mainly the beam supporting its main body) adopts a pure reinforced concrete structure, because it cannot withstand external forces before solidification, it is even necessary to rely on the reinforcement cage on other structures to ensure its accurate position during construction, and it is necessary to set up a formwork frame and scaffolding; and when the ground height of the air corridor is high, the erected formwork and scaffolding are easy to lose stability, and the relevant regulations do not allow this

Another way is to hang formwork trusses between two tall buildings. Although this solution is feasible, it requires high cost and is difficult to disassemble.
