Reinforced concrete steam turbine platform beam bolt casing pipe top template construction method

Abstract

The invention particularly relates to a reinforced concrete steam turbine platform beam bolt casing pipe top template construction method which is characterized by including (1) a step of installing a steam turbine platform beam bottom template, (2) a step of manufacturing a circular template, (3) a step of flicking lines and lofting, (4) a step of fixing the circular template, (5) a step of conducting platform beam steel bar and template construction, installing longitudinal steel bar and transverse steel bars by avoiding the circular template according to a position of the installed circular template in the process of installation of the steel bars, installing a side template of a platform beam and an edge template of a reserved opening after installation of the steel bars are examined and received, (6) a step of installing bolt casing pipes, (7) a step of pouring concrete, (8) a step of vibrating and pounding the concrete, and (9) a step of removing the templates, and then removing the steam turbine platform beam side template and the bottom template after strength grade of the concrete meets requirements of the design, wherein the circular template can automatically drop along with the bottom template and the bolt casing pipes are communicated. The circular template is simple in structure, convenient to manufacture and install, low in cost and convenient to construct. The bolt casing pipes are high in installation accuracy.

Description

technical field [0001] The invention belongs to the construction field of reinforced concrete structures in construction engineering, and in particular relates to a method for constructing a reinforced concrete steam turbine platform beam bolt casing top form. Background technique [0002] At present, the reinforced concrete steam turbine foundations in the known power generation field are all connected with the steam turbine by long bolts, and almost no bolts are directly buried on the reinforced concrete steam turbine foundation, but carbon steel pipes are pre-embedded inside the reinforced concrete foundation. After the concrete construction is completed, After the equipment installation conditions are met, the long bolts are passed through the casing, so that one end of the bolt is anchored on the steam turbine equipment, and the other end is anchored under the reinforced concrete equipment foundation, so that the steam turbine equipment and the reinforced concrete founda...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that there is no professional pre-embedding method for bolt sleeves in the foundation construction of reinforced concrete steam turbines in the prior art, which leads to conflicts between the bolt sleeves and the designed steel bars during the installation process, resulting in verticality deviation and displacement deviation of the bolt sleeves , Integral deviation defects, providing a bolt casing top formwork construction method for reinforced concrete steam turbine platform beams with high bolt casing installation accuracy
