Embodiment Construction

[0032] A construction method for overall embedded hoisting of a large cantilever beam with front support and rear stretching, comprising the following steps:

[0033] (1) Construction preparation:

[0034] Pre-embedding of the base: According to the position of the connection point with the concrete column in the 3D three-dimensional truss diagram, the connector is pre-embedded when the concrete column is poured; the base of the connection point between the column and the large cantilever beam has four points, two points are located on the top of the column, and two points are located at the top of the column. The point is located on the front upper side of the column; the base of the ball hinge connection point of the V-shaped truss of the front brace is one point, and the base of the upper and lower connection point of the rear pull sheet truss and the back of the column is two points;

[0035] (2) Ground assembly

[0036] 1. The steel pipe fittings of the main trusses are ...

Abstract

The invention discloses a front-supporting rear-pulling large cantilevered beam overall-embedded type hoisting construction method which comprises the steps of construction preparation, ground assembly, hoisting preparation, hoisting of a primary truss, lateral transverse moving of the primary truss, positioning and fixing and the like. According to the front-supporting rear-pulling type large cantilevered beam overall-embedded type hoisting construction method, due to the fact that an overall-embedded type hoisting technology is adopted, a suspended supporting jig frame is not needed to be set up, construction cost is greatly saved, and installing progress is ensured. The front-supporting rear-pulling large cantilevered beam overall-embedded type hoisting construction method is good in construction quality.

Description

technical field [0001] The invention relates to a construction method for integrally embedded hoisting of a large cantilever beam with front support and rear expansion. Background technique [0002] In the architectural design of modern large-scale venues, various complex aerial steel structures are used more and more. While the shape is novel, the difficulty of installation is also increasing. For Rugao Sports Center Stadium project, the roof steel structure is arranged in an open-center oval shape, and the upper part of the surrounding stands is designed with a pipe truss roof. If the conventional support tire frame is used and then hoisted step by step, not only the construction cost will be higher, but also the construction period required by the owner will definitely not be met. Contents of the invention [0003] The purpose of the present invention is to provide a construction method that is convenient for construction and has good quality and is integrally embedded...
