The items that need to be prepared before the construction of the steel formwork are: data, shaped combination steel formwork blocks and large formwork. Shaped steel angle mold, yin and yang angle mold, joint angle mold. Attachment accessories, u-shaped cards, hook bolts, fastening bolts, etc. Support system, steel tube support, column mold clamps, etc.
The classification of the steel formwork is as follows: when the steel formwork falls to the working surface of 30m/m, it should be stopped. The loose form is loosened by the synchronous force-increasing demolding mechanism. use. The suspension and movement of the steel formwork is carried out by the ground. Before the mold is dropped, the height of the support section should be controlled to be less than the height of the steel formwork, so that the upper part of the steel formwork is pressed against the old mandrel by about 50m/m to make the joint tight and ensure that there is a bottom gun at the bottom of the steel formwork. After the height of the empty slab reaches the requirement, the section is inspected and the design is required to be leveled. The level of the symmetry pad around the well wall is eight blocks and is leveled. When the mold is dropped, the well should be connected up and down. Put down the folding scaffolding and clean the steel formwork and apply butter to the active part of the screw. Using the center line to level the steel formwork should be measured symmetrically in the upper and lower parts of the template to determine the net diameter of the wellbore to meet the design requirements. When pouring evenly into the joint section, reduce the amount of pebbles and add shock to ensure that the joints are tight and flat. The steel formwork is externally coated with a release agent and ready for watering. The steel formwork design can design the steel formwork according to the engineering structure form and characteristics and the on-site construction conditions. The plan layout of the vertical and horizontal keel specifications, the quantity arrangement size, the type and spacing of the column hoop selection, the beam plate support spacing, the steel formwork assembly form, the connection node The large sample checks the strength stiffness and stability of the steel formwork and support. The wood template has low recycling efficiency and large loss, and the plywood can be bent within a certain range, so that it can also be made into a curved template with different curvatures. The bending performance of bamboo plywood is superior to that of curved, silos, water towers and circular piers of wooden plywood high-rise buildings. According to the steel template design drawing, each hole of the adjacent two boards should be clamped with a u-shaped card. The column template should be reserved for cleaning when assembling. Prefabricated assembly can be assembled and leveled. After the steel formwork is assembled, the numbers are numbered and the release agent is applied to the specifications for stacking. Place the axis, the template edge, the horizontal control level steel template bottom to make the cement mortar leveling inspection and correct the ground anchor for the column has been pre-buried.
