Network frame house cap integral lifting construction method

Abstract

Disclosed is a construction method for lifting whole spatial grid roof structure, pertaining to the technical field of lifting a spatial grid roof structure. The spatial grid roof structure at which the method aims is composed of the connection of node spheres and tie bars; the whole spatial grid roof structure is supported and fixed by an upright column. The construction method is characterized by comprising the steps that: arranging a bearing upright column, connecting a lower girder, adjusting a radius rod, lifting an upper girder, installing a jack, arranging a bending- resistant lead, removing the original connection of the spatial grid roof structure, starting the jack to jack the whole spatial grid roof structure, padding the upper girder and jacking again, lengthening a connecting upright column and removing jacking facilities. The construction method adopts the combination of a hydraulic jack and girder multipoint supporting structure and directly jacks the whole spatial grid roof structure, which can shorten construction period, reduce construction amount as well as makes full use of the original structure; the construction method has components and equipment which are easy for manufacturing and convenient transportation and assembly, reduces project expenses, is fast and highly efficient, has low expense and is applicable to the heightening improvement of spatial grid roofs with various structures, such as circle, polygon, irregular odd shape, etc.

Description

technical field [0001] The invention belongs to the technical field of grid roof lifting, and in particular relates to an overall lifting construction method of grid roof. Background technique [0002] The grid structure building has the characteristics of large construction span, sufficient effective space, and short construction period. At the same time, its structure is simple, light in weight, and convenient for factory production. It is especially suitable for large shopping malls, factories, stadiums, stations, airports, ports, and garages. Seedling farms, farms and other fields are very valuable buildings. Judging from the current use status, its biggest disadvantage is that it is difficult to remodel. If it is necessary to add floors after the construction is completed, the current method is to remove the roof and rebuild it, and the bolts and roof of the original grid roof Panels, gutters, etc. cannot be used and need to be remade, which can be described as a large...

Judging from the current use status, its biggest disadvantage is that it is difficult to remodel. If it is necessary to add floors after the construction is completed, the current method is to remove the roof and rebuild it, and the bolts and roof of the original grid roof Panels, gutters, etc. cannot be used and need to be remade, which can be described as a large amount of engineering, long construction period, and high cost
