1. Lifting of frame column: put tires under the column and straighten the column in place. Grouting of frame column: the grouting joint is blocked and the formwork is closed. Hoisting of lotus root beam: install lotus root beam, first pass the four corners of steel bars, and then other steel bars enter the holes. Hoisting of primary and secondary beams: install primary and secondary beams, install and adjust primary and secondary beams, and connect steel bars and sleeves.

2. Precast floor hoisting: composite floor hoisting, hook truss reinforcement hoisting, support erection, preparation and completion. Precast floor steel binding: connecting steel binding and bearing steel binding. Stigma grouting: positioning correction of stigma reinforcement, fixing position of stigma reinforcement, stigma grouting and stigma supplementary grouting.

3. Binding of beam and slab reinforcement: The position, quantity and spacing of beam and slab reinforcement need to be marked in detail to ensure the correct installation and fixation of reinforcement during construction. Layout plan of embedded parts: The location, quantity, specifications and other information of embedded parts need to be clearly marked, so that the embedded parts can be accurately placed in the corresponding positions during construction.

The importance of composite floor construction drawing is as follows:

1. Make the image of the project more intuitive and concrete: The superimposed floor construction drawings can show the design scheme in the form of concrete images, so that the owners and constructors can have an intuitive impression on the project, better understand the design intent and key points, and provide convenience for subsequent construction and communication.

2. Conducive to the reasonable arrangement of the construction scheme: The construction drawings of the reinforced floor include information such as elevation control of different parts of the project, material selection, relative positions of various components, etc., which provide technical personnel and management personnel with a reference basis for the construction scheme and steps, and help to realize the reasonable arrangement and scientific management of the construction.

3. It is an important basis for budget and cost control: high-quality composite floor construction drawing is the basis for budget and cost preparation. Through the continuous optimization of drawings, while ensuring the building function, the project investment is reduced and the construction cost is saved. Convenient for later maintenance: The construction drawings of reinforced floor can provide detailed building information and data for later maintenance.
