Problems solved by technology

For the formwork support structure design and layout of the reinforced concrete suspended structure of such tower buildings (structures), the rigid formwork support construction technology theory is still dominant, that is, the formwork support system with high brackets or the steel truss support system are used to compress Or the control design of bending components, the construction is difficult, the construction cost is high, the construction period is long, and there are many unsafe factors; the scissors bracing and lateral bracing closely related to the space safety and stability of the rigid formwork support system are generally only used as structural measures , the theoretical calculation is relatively vague, and it is easy to be ignored by the construction personnel

Embodiment Construction

[0040] A construction method of a spatial suspension cable structure formwork supporting platform includes the following steps in sequence:

[0041] (1) Installation platform: A simple truss is composed of horizontal I-beam 1 and steel pipe diagonal braces 2, and two adjacent simple trusses are combined according to their positions. The steel pipe fastener railing 3 is arranged on the I-beam. It is hoisted, placed and fixed on the corresponding support position on the reinforced concrete structure, and the end is fixed in the embedded lifting ring of the upper reinforced concrete structure by two sets of diagonal-stayed steel wire ropes 4 obliquely pulled to form a temporary operating platform suitable for operation by operators. ; Temporary operation platform is arranged symmetrically on each side;

[0042] (2) Install the central rigid ring cylinder: Before the ring cylinder 5 is hoisted, prepare the load-bearing cable 6 for temporary installation and the stabilizer cable 7 for i...

Abstract

The invention discloses a method for constructing a template supporting platform with a spatial span wire structure, which comprises the following steps that: the mounting of a cantilever platform, the mounting of a central rigid annular cylinder, the mounting of a thread steel bar bearing cable, the mounting of a simple truss, the mounting of a lateral strut on the simple truss and a steel ring strut on the central rigid annular cylinder and the like. The built template supporting platform with the spatial span wire structure has a reasonable structure, convenient construction and good effect.

Description

Technical field: [0001] The invention relates to a construction method of a space suspension cable structure formwork support platform. Background technique: [0002] A large amount of literature shows that the suspension cable structure has the characteristics of economy, various structural forms, flexible layout, and can meet the needs of large-span space. It is increasingly applied to permanent structures such as bridges and housing constructions, but its construction The difficulty is generally very high, and a large number of temporary support structures are required to meet the construction needs of the suspension cable structure. [0003] Due to the large deformation of the suspension cable structure under load, and the obvious geometric nonlinear characteristics, the general engineering and technical personnel classify it as a flexible structure, and it is difficult to install and dismantle, so it is very useful in the application field of temporary support in engineering c...
