Embodiment 1

[0068] The integrated construction method of steel beam, concrete ring beam, and concrete floor structure provided in this embodiment includes the following steps:

[0069] (1) Bolting of embedded parts

[0070] The embedded parts are bolted into the ground before hoisting. The high-precision bolting method ensures the overall construction quality of the later steel beams. The specific operations are as follows:

[0071] 1 Bolting and tightening: do initial and final tightening when bolting. In order to reduce the difference between the pretension of the high-strength bolts that are tightened first and tightened later, the tightening must be divided into two steps: initial tightening and final tightening. For large nodes with a large number of bolts, a re-tightening process and re-tightening torque are required. It is still equal to the initial tightening torque to ensure that the bolts reach the design value.

[0072] 2 Tightening inspection: The torque wrench used for tightening th...

Abstract

The invention discloses a steel beam, concrete ring beam and concrete floor structure integrated construction method. The steel beam, concrete ring beam and concrete floor structure integrated construction method comprises the following steps that (1), built-in fittings are connected in a bolted mode; (2), a full-hall frame is erected; (3), a steel beam is hoisted and installed and fixed; (4), beam main steel bars and stirrups are arranged in advance and positions are reserved; (5), formwork erecting and steel bar binding are performed; and (6), concrete pouring and maintenance is performed. The built-in fittings (anchorage parts) and the steel beam are welded and connected in a bolted mode in a factory and then lifted to the designed elevation to be subjected to overall pouring with concrete ring beam slabs and columns though a deepening design of the steel structure, the positioning accuracy of the steel beam is improved, the number of concrete pouring is reduced, and the construction period is saved. According to the construction method, the built-in fittings and the steel beam are connected in the bolted mode on the ground in advance, the aloft work is reduced, and safety is improved. The integrated construction method specifies the steel bar binding sequence at the position of column and ring beam caused by the pre-installation of the steel beam, and can meet the quality requirements of steel bar binding.

Description

Technical field [0001] The invention relates to an integrated construction method of steel beam, concrete ring beam and concrete floor structure, belonging to the technical field of building construction. Background technique [0002] With the development of economy, the structural situation of buildings is becoming more and more diverse. In the process of large-scale stadium construction, in order to improve the space utilization rate and achieve beautiful and practical effects, it is more common to use steel beams instead of traditional concrete beams. In the conventional construction process, the method of burying the embedded parts to pour the reinforced concrete ring beam, then installing the steel beam, and then pouring the roof concrete is often adopted. Although this process is more common, it requires high precision for hoisting and high-altitude operations. More, complicated procedures and longer construction period. Summary of the invention [0003] The technical probl...
