Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] A roof reticulated shell structure cantilever installation method without supports, comprising the following steps:

[0021] Step (1) Installation of embedded parts

[0022] According to the requirements of the design drawings, the embedded parts are buried under the control of the positioning template according to the position and positioning dimensions of the drawings. In order to prevent the embedded parts from shifting during the concrete pouring process, which will adversely affect the installation of the reticulated shell, the embedded parts and The formwork is permanently fixed with fixed brackets; after the embedded parts are positioned, the measurement review is carried out immediately, and the concrete pouring construction is carried out after meeting the requirements of the specifications and design tolerances. The elevation point is ...

Abstract

The invention provides an installation construction method of a roof lattice shell structure without supports and cantilevers. An existing installation method needs a plurality of installation tools and scaffolds, and is high in working cost and low in speed. The method provided by the invention comprises the following steps of installing built-in fittings on the ground, permanently fixing the built-in fittings, then assembling lattice shells on the ground, lifting the lattice shells by using a truck crane for the installation of a first block lattice shell, completely installing the first block, installing the left blocks in sequence. The method has the following advantages that the lattice shells are spliced on the ground according to a design; the truck crane lifts the cantilevers to install all the lattice shells without the need of using large lifting equipment and the scaffolds; the internal parallel work is not influenced; in construction, the work at multiple aspects is implemented, and multiple types of work are simultaneously and crossly constructed; therefore the construction period is shortened greatly, and the installation speed is high.

Description

technical field [0001] The invention relates to a building construction method, in particular to a roof reticulated shell structure cantilever installation and construction method without supports. Background technique [0002] The roof structure of the coal storage and material storage facilities in thermal power plants mostly adopts the bolt spherical reticulated shell structure. Since the installation of the large-scale equipment foundation and the coal shoveling conveying system in the coal yard has been completed before or simultaneously with the construction of the upper reticulated shell, a high-altitude scaffolding is used The bulk method, the scaffold sliding method and the overall jacking method cannot be implemented, and the construction of the reticulated shell by accumulating and sliding method requires more construction tools and sliding track equipment, which is costly and is not the best construction method. Contents of the invention [0003] The present in...
