Assembly type large-span wooden beam string structure hoisting construction method

Abstract

The invention relates to an assembly type large-span wooden beam string structure hoisting construction method. The method comprises the following operation steps of using finite element software to carry out a numerical simulation analysis of the construction process of an assembly type large-span wooden beam string structure; carrying out accurate blanking and machining of the assembly type large-span wooden beam string structure; erecting a supporting jig and an operation platform on the ground; hoisting a beam string to the supporting jig (and doing a good job of lateral support); laying asteel pulling cable; installing a cable head and a cable clamp node; performing cable tension tensioning; and hoisting and installing the assembly type large-span wooden beam string structure in place. The method realizes the predictability and controllability of the construction process of an assembly type large-span wooden beam string structure construction process system, ensures the structural safety during the construction process, makes a bending component and a tensile component be fully used and work together, so as to achieves self-balance, improves the rigidity and stability of thesystem, and makes the construction completion state meet the design requirements.

Description

technical field [0001] The invention belongs to the technical field of prefabricated wooden structure construction, and in particular relates to a construction method for hoisting a prefabricated large-span wooden tension string beam structure. Background technique [0002] With the advancement of society, science and technology and the rapid development of the economy, many large-scale venues have been built in my country in the past ten years, and their shapes are even more distinctive and endowed with certain meanings. In these large venues, the long-span tension beam structure system has been widely used due to its high-efficiency, economical and beautiful structural features. Assembled wood structure is a structural form vigorously developed by the country. Among them, the assembled glulam string beam structure has been developed due to its excellent structural performance. Therefore, the assembled long-span wooden string beam structure system is a promising new structu...

Problems solved by technology

[0003] However, the prefabricated long-span wooden string beam structure has special requirements for installation and construction. Compared with the steel structure string beam, the wooden string string beam has the characteristics of soft rigidity and poor lateral stiffness. It is especially used in large-span structures. During the construction process And it is prone to weak overall stability and lateral instability of structural components
