What is the overall lifting method of the membrane structure grid? Today we first have an understanding and understanding of the overall lifting method of the membrane structure grid. In the membrane structure industry, we still need to learn a lot of professional knowledge of membrane structure. Through continuous learning of new knowledge, we will gradually become more professional.

Several methods of lifting are based on the form and weight of the net frame, and the use of hydraulic penetrating jacks, steel strands (screws), and pumping stations with different lifting capacities for net frame lifting. During the lifting stage, the support of the grid frame remains unchanged, and the membrane structure column used generally does not need to be reinforced. If a corbel is made on the top of the column or a pull rod (put lifting equipment or lifting anchor point) is used, the stability of the structural column must be checked. If it is not enough, take measures to stabilize the column or pull rod, such as installing cable wind.

In order to better utilize the superiority of the overall lifting method, the membrane structure grid roof panel, waterproof layer, ceiling, heating and ventilation and electrical equipment can all be constructed on the ground and at the most favorable height, which can greatly save construction costs. Through the checking calculation of the lifting equipment, when the whole roof structure cannot be improved, part of the roof structure can be installed and then lifted. It should be noted that, in order to prevent local cracks caused by distortion during the lifting process of the roof structure after installation, necessary reinforcement treatments must be taken. Both the single lifting grid method and the grid climbing method need to connect a high steel column about 2 to 3m on the top of the original column, and add a cantilevered corbel to set the lifting anchor point. The operating platform of the single-lift membrane structure grid method is set on the high steel column, and the operating platform of the grid climbing method is set on the upper chord plane of the grid.

The grid support of the lifting beam and net method should be placed in the middle of the ring beam, and the grid support of the lifting net slip form method should be placed on the top of the column. The single lifting grid method and the grid climbing method can be placed in the middle of the ring beam or On the top of the column. The overall lifting method of the membrane structure grid is generally suitable for being assembled on the ground at the design plane position and then vertically lifted in place. If the net frame needs to be moved horizontally after being raised vertically to the design elevation, an additional cantilever structure shall be added and the sliding method shall be combined to construct it to the design position.
