What are the problems with the use of cylindrical steel formwork

What problems will occur when cylindrical steel templates are used? Hubei Wangke Template Co., Ltd. will take you to find out.

1. The problems that are prone to cylindrical steel formwork are: inaccurate section size, excessive concrete cover, and column Distorted body. The prevention method is: before the mold is supported, the position line is adjusted according to the diagram, the position of the steel bar is corrected, and the front pillar of the pillar should be made of a small square plate steel template to ensure the accuracy of the bottom position. According to the cross-sectional size and height of the column, design the column hoop size and spacing, and make support and tie rods at the four corners of the column.

2. The problem that beams and plate steel templates are prone to is: the beam body is not straight and the bottom of the beam is not flat. The side of the beam bulges, the upper mouth of the beam is too large, and the middle of the plate is bent downward. The prevention method is: the beam and plate steel formwork should be designed to determine the size and spacing of the keel and pillars, so that the steel formwork support system has sufficient strength and rigidity to prevent deformation of the steel formwork when concrete is poured. The bottom of the steel formwork pillar should be supported on a solid ground with long scaffolds to prevent the pillar from sinking. The beam and plate steel formwork should be arched according to the design requirements to prevent excessive deflection. The upper mouth of the bridge formwork should be locked with tie rods to prevent deformation of the upper mouth.

3. The problem that wall steel formwork is prone to is: the thickness of the wall concrete is inconsistent, and the cross-sectional size is inaccurate. The splicing is not strict, and the seam is too large to cause the slurry to run out. The steel formwork shall be designed according to the height and thickness of the wall to determine the size and spacing of the vertical and horizontal keels, the support method of the wall, and the form of the corner mold. The upper mouth of the steel formwork should be provided with a tie to prevent the upper mouth from being too large.

As a member of the building template, cylindrical steel formwork is widely used, so the cylindrical steel formwork is in the construction What should I pay attention to? The editor will take you to find out.

1. Personnel entering the construction site need to wear a hat, and work at heights need to fasten the belt.

2. When disassembling molds, they should cooperate with each other, work together, and don’t throw tools when transferring them.

3. The template shall be set up so that the materials are clean and the site is clean after the work is completed, and the materials need to be placed neatly.

4. The hoisting transfer template shall be directed by a special person, and no illegal operations are allowed.

5. Do a good job of environmental protection education for employees before entering the site to improve their environmental awareness.

6. Strengthen mechanical management and reduce noise during construction.

The above is a brief analysis of what needs to be paid attention to during the construction of cylindrical steel formwork. I hope it can help everyone!
