Installation steps of shear wall formwork

09 Nov 2020 Tags: circular column forms concrete column forms

1. Before shear wall formwork construction, the measurement and positioning work should be done, including the layout of the axis control network in the plane coordinate system and the layout of the site elevation control network.

2. Shear wall formwork system are generally standard sections. In actual projects, standard sections and non-standard sections are used in combination. Non-standard sections are usually cut from standard sections. The segments are mostly connected by high-strength bolts, and sometimes they are connected by welding.


3. The shear wall formwork system is transported to the designated position by the crane, and the construction personnel put the hydraulic jack between the movable end and the bearing plate, and pre-add the axial force step by step according to the design specification. The prestress cannot be applied in place at one time, and should be applied in stages to ensure the safety of the support. In the process of supporting the axial force, the actual monitoring data should be the mainstay, and the manual inspection should be supplemented. The main object of adding axial force is the support of each layer above the axial support to be added and the support that has been installed for a long time. Each layer of support under the same section should be combined with axial force at the same time. The value of the added axial force should be determined by technical specifications and actual conditions. It is strictly forbidden to apply axial force to only a single steel support, otherwise it may cause The force of the nearby support shaft decreases rapidly, causing it to fall off. Currently, there are two types of dynamic axial force compounding devices, screw type and hydraulic type, on the market. In order to ensure the safety of the entire enclosure and support structure, professional prestressing equipment can be used to dynamically monitor and reinforce the supporting axial force.


4. The removal of shear wall formwork system must be carried out in strict accordance with the pre-designed construction plan and corresponding technical specifications. Before removing the steel supports, it must be ensured that the prestress is released.
