Embodiment Construction

[0022] Specific embodiments of the present invention are given below to further describe the composition of the present invention in detail.

[0023] The construction method of the steel formwork firewall comprises the following steps:

[0024] (1) Firewall foundation pouring

[0025] Process the steel bars of the firewall. The steel bars are anchored into the foundation of the firewall. After passing the inspection by the supervisor, the foundation concrete of the firewall is poured. When the concrete is leveled, a photoelectric leveling instrument is used to strictly control the surface flatness of the foundation concrete. The error is less than 2mm, which meets the requirements of steel formwork installation. Levelness and verticality requirements;

[0026] (2) Steel formwork support

[0027] ?After the steel formwork is polished with an electric grinder, brush the formwork wax twice to prevent the concrete from sticking to the steel formwork, which will affect the appear...

Abstract

The invention relates to a construction method for a steel molding plate fireproof wall and belongs to the technical field of construction methods. The construction method for the steel molding plate fireproof wall includes the following steps that (1) a fireproof wall foundation is formed through pouring operation, reinforcing steel bars of the fireproof wall are machined and anchored in the fireproof wall foundation, fireproof wall foundation concrete is poured after the reinforcing steel bars are verified to be qualified by a supervisor, a photoelectric planometer is adopted in the concrete leveling process, the surface flatness of the foundation concrete is strictly controlled, the error is smaller than 2 mm, and the requirements for levelness and perpendicularity of steel molding plate installation are met. The construction method for the steel molding plate fireproof wall has the following advantages that the manufacturing accuracy of a steel molding plate is high, the width of the steel molding plate is large, joints generated in the steel molding plate splicing process are reduced, the joints are tight, and the phenomena of concrete running and leakage are avoided.

Description

technical field [0001] The invention relates to a construction method for a steel formwork firewall, and belongs to the technical field of construction methods. Background technique [0002] Ordinary wooden formwork firewalls have high finished products, large waste of resources, poor precision and appearance quality, many joints in the formwork assembly, and the joints are not tight, and it is prone to pulp leakage and leakage. Moreover, the strength of the wooden formwork parts is relatively low, the combined stiffness is relatively small, the reinforcement is difficult, and the formwork is easily deformed, resulting in uneven concrete surface. In addition, the overall rigidity of the plane of the panel made of wooden templates is low, and the load-bearing capacity of the formwork composed of panels is small, and it needs to be reinforced with supports, which is not convenient for overall hoisting. The construction process is complicated, the process progress is slow, the...
