Steel reinforced concrete structure formwork sleeve threaded rod pulling construction method

Abstract

The invention discloses a steel reinforced concrete structure formwork sleeve threaded rod pulling construction method. The method comprises the steps that firstly, a section steel framework is installed; secondly, steel bars are bound; thirdly, a formwork sleeve threaded rod pulling system is installed preliminarily, specifically, the formwork sleeve threaded rod pulling system comprises a plurality of transverse sleeve threaded rod pulling devices and a plurality of longitudinal sleeve threaded rod pulling devices, the transverse sleeve threaded rod pulling devices and the longitudinal sleeve threaded rod pulling devices each comprise two formwork sleeve threaded rod pulling pieces, and each formwork sleeve threaded rod pulling piece comprises a connecting steel bar, an inner embedded sleeve, an outer embedded sleeve and an outer threaded rod; fourthly, formworks are installed and reinforced; fifthly, subsequent installation of the formwork sleeve threaded rod pulling system is conducted; sixthly, concrete is poured; and seventhly, the formworks are removed. The method is simple in step, reasonable in design, easy and convenient to implement and good in using effect, by the adoption of the formwork sleeve threaded rod pulling pieces based on straight threaded sleeves, the steel reinforced concrete structure formworks are fixed easily and effectively, and holes do not need to be drilled in the section steel framework.

Description

technical field [0001] The invention belongs to the technical field of steel concrete structure construction, and in particular relates to a steel concrete structure formwork sleeve screw tie construction method. Background technique [0002] With the rapid development of my country's construction industry, various new structural forms continue to emerge. The steel concrete structure (also known as the steel concrete composite structure) caters to the Development of building structures. The steel concrete structure is an independent structural form in which the steel is embedded in the reinforced concrete structure. Due to the addition of section steel in the reinforced concrete structure, the section steel works with its inherent strength and ductility and the trinity of section steel, steel bar and concrete, so that the section steel concrete structure has a larger bearing capacity, greater rigidity, and better seismic performance than traditional reinforced concrete struc...

Problems solved by technology

However, in the formwork support of the steel concrete structure, because the steel is added to the reinforced concrete member, it is generally not allowed to open holes on the steel

In this way, due to the blockage of the rigid steel skeleton (that is, the steel skeleton) in the steel-concrete structure, the traditional tension screws cannot pass through each other, which brings certain difficulties to the support and reinforcement of the formwork system
