Construction method for steel reinforced concrete batter post of underground structure

Abstract

The invention discloses an underground structure steel reinforced concrete batter post construction method, and relates to the technical field of steel reinforced concrete construction, and the method comprises the following steps: S1, measurement positioning, S2, pretreatment, S3, batter post middle section profile steel installation, S4, batter post middle section steel bar installation, S5, batter post middle section template installation, and S6, batter post middle section concrete pouring. The construction method is suitable for mounting the steel reinforced concrete combined batter posts with different inclination angles, and particularly has universality for the steel reinforced concrete combined batter posts with a large number and different inclination angles in some large underground structures.

Description

technical field [0001] The invention belongs to the technical field of steel concrete construction, and in particular relates to a construction method for steel concrete slanted columns of underground structures. Background technique [0002] With the high-quality development of my country's social economy and the rapid increase of urban population, traffic congestion in urban core areas has become increasingly serious. In order to meet people's needs for improving travel efficiency, large-scale underground rail transit hubs have been built. Under the premise of meeting the functional requirements of the hub , more and more hubs with beautiful shapes and large underground space use area have sprung up like mushrooms after rain. Since the beginning of this century, steel concrete structures have developed rapidly in the construction field. The existence of profile steel has greatly improved the bearing capacity of components. During the construction phase of the main structure ...

[0002] With the high-quality development of my country's social economy and the rapid increase of urban population, traffic congestion in urban core areas has become increasingly serious. In order to meet people's needs for improving travel efficiency, large-scale underground rail transit hubs have been built. Under the premise of meeting the functional requirements of the hub , more and more hubs with beautiful shapes and large underground space use area have sprung up like mushrooms after rain. Since the beginning of this century, steel concrete structures have developed rapidly in the construction field. The existence of profile steel has greatly improved the bearing capacity of components. During the construction phase of the main structure of the main structure, steel concrete slanted columns are often used as load-bearing columns in order to obtain a larger use space and a good facade effect. Pouring and vibrating are not in place and other problems. In view of the existing problems in the construction of underground steel concrete slanted columns in the prior art, such as complex construction, difficulty in installing steel profiles, insufficient concrete pouring and vibrating, and non-universal construction methods, the present invention provides Construction method of steel concrete slanted column for underground structure
