How to construct to achieve better results, the treatment of every detail is very critical! Below, the construction process of building formwork brought by Lianzhuzhuan, I hope to help you!

1. Measuring and Paying Out

Before the formwork is supported, the builder is required to lay out lines around each shear wall and column according to the requirements of the drawings, and draw each axis, control line and shear wall edge. www.3plyplywood.com

Then weld on the edge line of the component section and the section control line. The inner section control line of the shear wall needs to be set at a distance of more than 600mm, and it needs to be set at a position about 6cm from the top of the plate to ensure that there are two columns in each direction of the column. welding wire.

2. Scaffolding tower

As the support system of the formwork, scaffolding is the premise of laying the formwork. The tower setting of the scaffold generally requires that the distance between the vertical poles under the slab of the standard floor is not more than 1.2m, the distance between the supporting poles under the beam is not more than 0.9m, the distance between the sweeping poles from the floor is ≤200mm, and the step distance of the first horizontal pole is ≤1.5m.

If the plate thickness is greater than 120 or the story height is greater than 3m or the beam height is greater than 700, the support system needs to be implemented according to the special plan.

3. Beam bottom formwork support https://www.3plyplywood.com

When the bottom formwork of the beam is supported, limit fasteners must be set on both sides, and the two ends of the same span must be installed. A limit fastener is set every two small cross bars in the middle. After completion, the formwork is laid. . www.3plyplywood.com

4. Beam side formwork support

In the support of beam side formwork, it is necessary to reinforce the pull screw or "wood clamp". During operation, if the beam height exceeds 600mm and the side beam side formwork is encountered, the pull rod needs to be reinforced.

Five, plate formwork support https://www.3plyplywood.com

After the formwork is laid, it is necessary to check the elevation and flatness of the formwork surface by drawing the line on the elevation line and the diagonal line. Usually, a 500mm diagonal line needs to be used for inspection.

Six, wall column formwork support

When supporting the external wall formwork, it needs to hang down 200mm. After the wall formwork is completed on one side, the formwork limit strip needs to be set on the reinforced wall panel, which is generally placed in a plum blossom shape every 450mm. There are three layers of densification on both sides of the seam, one at the top plate, and two in the middle. The wall plate between the beam and the wall uses steel pipes to clamp the beam and the wall together as a whole to prevent the wall and beam from being misaligned.

Seven, formwork reinforcement

The reinforcement of the external wall columns needs to be in the form of a combination of pulling and roofing. The steel reinforcement nodes are embedded on the floor, and the distance between the cable-stays needs to be less than 2m, and the distance from the side of the wall column is greater than 50cm. At the junction between the upper and lower columns (walls), add locking screws, the distance between the locking screws is 100mm from the horizontal construction joint of the wall column, the spacing is not more than 750mm, and there should be no less than 2 locking screws on each side.
