Introduction to the steps and standards for the price of the steel structure of the workshop

The price of the steel structure of the workshop is a frame in the structural form, combined with the component form, weight, position and actual construction site The steel structure of this project adopts a comprehensive installation method to determine the price of the steel structure of the workshop.

1. The steel structure hoisting adopts the principle of 'first the middle, then the outer side, first the column and then the beam, first down and then up'. In the middle part of the workshop, a stable frame system is first formed, and then it is advanced to both ends, and the remaining steel columns and beams are installed symmetrically.

2. Re-measurement of anchor bolts - unloading of steel components - incoming inspection of components - direct hoisting of truck cranes in place - temporary tightening of anchor bolts - temporary pulling of cable wind rope Stable structure - steel column axis position, verticality adjustment - steel column bolts and column foot pressure plate fastening, welding - next steel column installation - steel column tie rod installation - forming the first stable lattice system - steel roof truss ground assembly The first steel roof truss - symmetrical installation columns on both sides, roof truss system - and so on until the installation is completed and the structure is accepted.

3. Install the second row of steel columns.

4. Install connecting beams (or tie rods) between steel columns.

5. Use the double machine to lift and install the first steel roof truss; use the double machine to lift to install the second steel roof truss.

6. Install the purlins between the two roof trusses to form a stable frame system; continue to install the steel columns, coupling beams, roof trusses, and purlins of the next rigid frame. Structure price.

7. Continue to install the roof truss in the above order, and the supports between the columns are also interspersed for installation; continue to install; the roof truss installation is completed.

After the roof steel beams are hoisted in place, the relevant roof steel purlins should be connected before the hooks are loosened to form a stable structure of the space frame. If the steel structure construction cannot install the roof steel purlin before loosening the hook, in order to prevent the roof truss steel beam from twisting, the cable wind rope should be pulled. Before hoisting, the cable wind rope is fixed to the steel beam of the roof truss. There are four cables in total. The pulling position is at 1/3 of the length of the steel beam.
