Embodiment Construction

[0019] The present invention will be further described below in conjunction with specific examples.

[0020] The metal roof of Zhengzhou Conference Center is made of 48 roof panels folded along folded trusses, in an umbrella shape, with a ridge slope of 18.5 degrees, a ridge length of 74 meters, and a roof area of ​​about 31,000m 2 . The space span is large and the height is high, the largest span is about 94000mm, and the highest point is about 54000mm. The skeleton composed of square tube and angle steel is used as the ceiling accessory frame and construction operation platform. The accessory frame is lapped on the purlin (H-shaped steel) of the secondary steel structure and spot welded. The square tube on the purlin is 80*80*4 , the horizontal keel of the vertical suspender uses 50*50*4 angle steel, bolts are used between the angle steels, and between the angle steel and the square pass. The plane formed by the horizontal keel and the main steel structure form a parallel c...

Abstract

The invention relates to a construction method of a reverse operation type metal suspended ceiling of an autonomous platform. The construction method comprises the following steps: building an access platform; finishing construction of a unit suspended ceiling framework at a joint between the suspended ceiling framework and a wall by the access platform; taking the finished unit suspended ceiling framework as a construction platform to perform forward construction to finish a next suspended unit ceiling framework; mounting a suspended ceiling false keel for the construction platform by the finished suspended ceiling framework after the suspended ceiling frameworks are joined at top; and mounting a suspended ceiling panel in the opposite direction above the suspended ceiling framework. Compared with the prior art, the method has the advantages of making full use of an original roof truss structure and a suspended ceiling keel structure by the autonomous platform reverse operation method to facilitate convenient and rapid construction; taking the suspended ceiling framework structure as a construction scaffold to greatly reduce cost, building no full hall scaffold to reduce cross-operation influence and shorten construction period; and using large safety net stretching technology to ensure construction safety.

Description

technical field [0001] The invention relates to a construction method of a metal suspended ceiling with a large span, a large space and a complex shape, in particular to a construction method of an autonomous platform reverse operation type metal suspended ceiling. Background technique [0002] The metal ceiling project with large span, large space and complex shape accounts for a very large proportion of the project cost in the whole decoration project. The traditional construction method is to build a full house of scaffolding. After the ceiling is completed, the wall and ground engineering construction is carried out. The traditional construction method is adopted The project cost is high, three-dimensional crossing operation is not possible, and the construction period is long, which has a great cross influence on sub-projects such as walls and floors. Contents of the invention [0003] The object of the present invention is to provide a construction method of an indep...
