How to improve the installation accuracy of workshop steel structure?
In the construction industry, steel structure building is gradually popularized, and steel structure workshop is also rising, and the corresponding production, transportation and installation technology is also getting more and more attention. How to further improve the manufacturing and installation accuracy of steel structure workshop is a subject in front of steel structure industry. Now let's know how to improve the installation accuracy of workshop steel structure.
1. Control of workshop steel structure fabrication and transportation
The accurate dimension of components in steel structure workshop is the basic and prerequisite to ensure the accurate dimension of the whole structure and the smooth installation of steel structure workshop. Therefore, it is necessary to accurately grasp the straightness and distortion of the steel column, the distance from the connection hole between the column and beam to the column base plate, the processing accuracy of the connection hole itself, the straightness of the roof beam and the processing accuracy of the column beam connection plate, the position size of the tie bar or support connection plate on the beam column relative to the beam column itself, and the position size of the purlin support plate.
In order to avoid the deformation of column, beam, tie bar and other connecting parts during transportation, the transportation company shall be required to increase more supporting points in the whole length range when binding the components, and the components shall be padded with wood or elastic material as far as possible, and the peripheral binding shall be firm, so as to minimize the deformation of components due to vibration or heavy pressure during transportation; two points shall be used during loading and unloading If the component is too long, the carrying pole can be used and the lifting points can be increased appropriately; when the component is stacked on the installation site, the number of stacking layers should be reduced as far as possible, generally no more than 3 layers, and the supporting points should be increased appropriately to prevent the component from being compressed and deformed. Do not relax the control of transportation, lifting and unloading, stacking and other links, otherwise, even if the steel structure workshop component manufacturing is more accurate, there will be problems due to transportation and other links, resulting in the normal installation of steel structure workshop.
2. Quality control of steel structure installation in workshop
Before the installation of the steel structure workshop, we should do a good job in the preliminary work. For example, before hoisting, the installation personnel should retest the components, and the hoisting can only be carried out on the premise that the components are not deformed and the installation size is correct. In addition, on the premise of confirming that the strength of foundation concrete meets the specification requirements, the installation personnel shall also detect the embedded bolts or cup mouth of steel column foundation. If deviation is found in the position and elevation size of foundation, the position of the part shall be recorded to adjust the position of steel column.
Dalian Guangtong Steel Structure Co., Ltd. can manufacture and install large-span environmental protection workshop steel structure for customers. It is made of steel product Q235B or Q355B, the seismic strength can reach grade 7, the surface is sandblasted and derusted, and the epoxy primer and polyurethane topcoat are used for anti-corrosion treatment.
