Embodiment Construction

[0018] The hoisting construction method of heavy ultra-high steel component of the present invention includes the following steps:

[0019] a. Component lofting: the steel structure refinement software is used to carry out the overall deepening design of the steel structure, and the beam-column connection node adopts the arc plate to strengthen all welding;

[0020] b. Pre-buried anchor bolts: Use angle steel to fix the anchor bolts as a whole, bind the fixing bracket and the bottom plate steel bar, add rigid supports around the fixed bracket, and then weld the anchor bolts and the bottom plate steel bar into a whole;

[0021] c. Hoisting the steel column: use a crane to lift the steel column using the single-machine rotation method. After the steel column is hoisted in place, insert the anchor bolt on the steel column bottom plate, place it on the adjusted nut, and place the steel column The center line of the four sides is aligned with the center line of the foundation line. When t...

Abstract

The invention discloses a construction method for hoisting a heavy type ultrahigh steel member. The construction method comprises the following steps: a, lofting the member; b, pre-burying foundation bolts; c, hoisting steel columns; d, correcting the steel columns; e, mounting column bracings; f, hoisting steel girders; g. mounting high-strength bolts. The construction method has the advantages of simple and convenient construction, short construction period, safety and reliability.

Description

Technical field [0001] The invention relates to a hoisting construction method of heavy ultra-high steel components. technical background [0002] Large-space buildings are used more and more in the field of industrial buildings and civil buildings. As a very attractive form of combined structure, steel reinforced concrete structure has unique advantages that other structures do not have, and it is increasingly widely used in various buildings and In the bridge structure, due to the addition of section steel to the reinforced concrete, the section steel works with its inherent strength and ductility, as well as section steel, reinforcement, and concrete, so that the section steel concrete structure has many advantages. However, during the construction process, the weight of the steel column greatly exceeded the maximum load-bearing value of the crane tower, and because of the difficulty in accessing large-scale civil construction machinery and tools, it was difficult to hoist hea...
