The scheme shall be formulated according to the requirements of the construction unit. It includes project introduction, construction deployment, template type selection and design calculation, preparation before construction, and construction technology.

Project description, including the area where the project is located, the number of floors required underground and above, what kind of rooms are required underground, equipment room, office room, commercial room, housing, etc. What kind of structure is the basement? For example, the basement building structure is frame-shear wall structure, and the main structure on the ground is frame structure; Building base area, total building area. The height of each floor, the height of each floor, the reasonable service life, the seismic grade, and the fire resistance grade.

Construction deployment

According to the building shape, it is divided into a construction section for flow operation. The construction sequence of each floor is the construction of walls, columns and other rigid components, and then the construction of floor beams and slabs.

Selection of template type and calculation amount

Template type

You can choose bamboo formwork, wood formwork, steel formwork and aluminum membrane plate.

Calculate the quantity according to the demand.

Construction preparation

Material preparation, plywood; square timber; Steel pipe; Wall bolts; Wall bolt sleeve; Yuanbao card fastener; Water soluble deagent. The formwork shall be designed and matched according to the engineering structure drawing to ensure the rigidity and stability; The reinforcement of the short-leg shear wall and column has been bound, the water and electricity pipelines and embedded parts have been installed, the reinforcement protective layer cushion blocks have been bound, and the concealed inspection procedures have been completed; Cleanouts shall be reserved for column and short-leg shear wall formwork during assembly.

Preparations before construction

1. Before installation, do a good job in positioning the template. The work steps are as follows:

Setting out the center line position: first, measure the setting out control axis of the building, and take this axis as the starting point; Measure each axis; When setting out the formwork, the inner side line and center line of the formwork shall be marked with ink line according to the construction drawing, and the side line and outer control line of the formwork shall be marked for the short-leg shear wall formwork to facilitate the installation and correction of the formwork; Do a good job in elevation measurement: use a level to measure the horizontal elevation of the building directly to the installation position of the formwork according to the requirements of the actual elevation; Leveling: the bottom of the formwork bearing pad shall be leveled in advance to ensure the correct position of the formwork and prevent mortar leakage at the bottom of the formwork. The leveling method is to plaster the leveling layer with 1:3 cement mortar along the edge of the formwork.

2 . The specification and quantity of the formwork and accessories required for construction shall be checked item by item, and the parts that have not been repaired shall not be used.

Erection and installation of formwork

The erection and installation of formwork shall comply with the following provisions:

Assemble in sequence according to the plate design to ensure the overall stability of the formwork system; The fittings must be installed and inserted firmly, and the bearing surface under the pillar should be flat and compact, with sufficient compression area required; Embedded parts and reserved holes must be accurately positioned and firmly installed; The horizontal bracing and diagonal bracing for the support shall be arranged according to the structure and overall stability; The columns supported by multiple layers shall be set on the same vertical centerline.

The formwork installation shall meet the following requirements:

The split bolt holes of the short-leg shear wall formwork shall be straight and opposite, and the penetrating bolts shall not be inclined to pull the hard top; The whole bar should be used for the steel ridge, and the joints should be staggered.
