The structure and assembly requirements of the mobile mold base

Hubei Wangke Template Co., Ltd. Introduce the following content: the structure and assembly requirements of the mobile formwork

1 The pier-side bracket and floor stand of the mobile formwork should have sufficient strength, rigidity and stability , The foundation must be solid;

2 Movable formwork for full-hole frame and movable bracket for stage assembly each

Before assembling, you must check the integrity of each component. After the assembly is completed, a comprehensive inspection and test shall be carried out, and the design requirements shall be met before it can be put into use.

3 The anti-overturning stability coefficient of the movable mold base and the longitudinal forward movement of the movable support shall not be less than 1.5.

4 mobile formwork and mobile support for segment assembly, (wet joints and dry joints) When moving forward, stabilization measures should be adopted for the bridge pier and the main truss beam of the temporary pier, and the slideway should have sufficient strength, rigidity, length and width.

5 The assembly of the corbel: the corbel is in the form of a steel box beam, and the corbel is on the top of the corbel when hoisting Use a level to level it so that the flat wagon slides smoothly on the top surface of the corbel.

6 Main girder installation: The main girder is assembled under the bridge, and the main girder can be installed with temporary brackets according to the lifting capacity on site. The sections are hoisted on the corbels and brackets. Remove the temporary support after forming a whole. It is also possible to use a large tonnage crane to hoist in place after all the main beams are assembled.

7 Assembling beams and external formwork: After the main beams are assembled, then the beams are assembled, and the beams are all installed. Afterwards, the main girder is accurately positioned in the transverse direction and along the bridge direction under the action of the hydraulic system. Release the bridge axis in the center of the pier, adjust the beam according to the direction of the bridge axis, and connect it with a pin. Then lay the bottom and outer webs, ribs and flanges.

8 Template assembly sequence: The mobile support system is assembled according to the following procedures: the assembly of the corbel, the assembly of the main beam And the installation of relevant construction equipment and machinery-----the installation of the corbels-----the hoisting of the main girder and the simultaneous horizontal movement and closing-----the installation of the beams-----laying the bottom plate and installing the template support- ----- Install the outer web, flange plate, and bottom plate ----- Install the inner mold (after tying the steel bars).
