Taking the pouring floor shear wall as an example, the specific application principle and application process of the system are explained in detail as follows:

1. Construction preparation

The materials involved in this system have increased the angle steel. The specification of the angle steel is 50×50×3mm, and it will be inspected after entering the site. The angle steel must be straight, and the two limbs must be vertical.

2. Processing and production of plugging angle steel

Before construction, the angle steel is processed according to the detailed drawing of the length of the shear wall on the floor, and a processing list is formed.

The processing length of the angle steel is: wall length - 3mm. For the inner corner part, one limb must be cut into a 45° angle, and spliced in pairs to avoid slurry leakage at the inner corner part.

Angle steel processing needs to be deepened according to the plan. After the material processing is completed, it is classified and stacked neatly according to the length. The lower part adopts a unified stacking rack. The processing process and finished product stacking must be standardized in the processing workshop, and open-air operation and stacking are prohibited.

3. Processing and welding of wall column positioning reinforcement

The processing of the positioning reinforcement at the root of the wall column is also an important part. The processing length of the positioning reinforcement is the wall width minus 6mm (2 times the thickness of a single support of the angle steel), and the ports must be flush and no unevenness.

After the floor measurement is completed, the welding of the positioning reinforcement can be carried out. The positioning reinforcement is perpendicular to the wall, and the welding height of the reinforcement axis is about 40mm higher than the floor elevation, such as 35-45mm. If the welding is too high, it will not limit the inversion of the angle steel. .

4. Blocking angle steel fixation

After the steel bar binding and water and electricity construction are completed, before the formwork is erected, the angle steel is placed and fixed with cement nails on both sides of the angle steel. At the same time, apply the release agent to facilitate the later removal and ensure the quality of the concrete. Then place them one by one according to the sequence of pre-processing numbers, and then install the formwork, which is the same as the traditional construction.

After the formwork is installed, it is necessary to check the installation of the angle steel to prevent the angle steel from being suspended and cause the concrete pouring process to leak.

5. Concrete pouring and maintenance

Before concrete pouring, detailed technical disclosure should be made to the operator, and the thickness of the floor slab and the flatness of the root of the wall column should be strictly controlled.

In the process of concrete pouring, it must be compacted by secondary vibration, especially the root of the wall column must ensure that the closed surface is flat, to avoid the angle steel and the finished surface of the concrete cannot be closely fitted, and the gap is too large to cause grout leakage and affect the quality of the concrete. After concrete pouring is completed, heat preservation and moisturizing maintenance shall be carried out in time.

6. Removal of plugging angle steel

When the concrete pouring is completed and the conditions for removing the vertical formwork are met, the angle steel can be removed. The angle steel should be dismantled and handled with care to prevent damage to the concrete. The concrete on the surface of the angle steel should be cleaned and stacked neatly for the next use.
