Detailed introduction and construction technology of cylindrical formwork

The cylindrical steel template is one of the cylindrical templates. What is the cylindrical template? Hubei Wangke Template Co., Ltd. will show you all about it

The building cylindrical template is composed of three parts: the panel, the supporting structure and the connecting parts. The panel is in direct contact Load-bearing slab of freshly poured concrete. Then, the supporting structure is a temporary structure supporting the panel, concrete and construction load, which can ensure that the cylindrical formwork structure is firmly combined so that it will not be damaged or deformed. Otherwise, the connector is an accessory that connects the panel and the supporting structure into a whole.

1. Compared with the traditional steel template, the cylindrical template itself is light in weight and does not require large-scale machinery installation;

2. After pouring, the concrete appearance is of good quality, with fewer joints, and it is reinforced with steel strips. The seam is tight, and the leakage of slurry and mold explosion can be basically eliminated;

3. High accuracy, using the finished cylindrical template, the cylindrical size after molding is consistent with the design requirements, and the roundness Accurate, simple construction, and further improve the accuracy of beam-column joints;

4. Cylindrical template can be processed according to the needs of the project, the template seam adopts concave and convex grooves, and the seams are tight Pulp;

5. Material saving, cylindrical reinforcement is simple, can save a large number of steel pipes, square wood and other materials used for reinforcement, and Easy to keep, high repetitive rate;

6. The cylindrical formwork has good thermal insulation performance, prevents bubbles and cracks, and helps control common defects in concrete quality.

What is the construction process for cylindrical steel formwork? How to protect the cylindrical steel formwork? The following editor shares the construction technology of the cylindrical steel formwork and the specific method of protection of the finished product. Let’s take a look at the construction process of the cylindrical formwork first:

1. Templates above three meters should be installed in a wrong position.

When installing the template, when the column height exceeds three meters, the two templates at the upper and lower connections of the template need to be installed staggered , Dislocation installation can ensure the verticality and integrity of the cylinder.

2, the fixed steel belt requires horizontal strapping.

Horizontal bundling can ensure that the steel belt is evenly stressed. The upper and lower margins of the fixed steel belt are 1 meter in diameter. Above, for the cylindrical formwork below 1.5 meters, one steel hoop is added for every 25cm, and 10% of the total steel hoop is added on this basis. Cylindrical templates with a column diameter of less than 1 meter are all made of a 30cm steel hoop (installation technique: use a steel ruler to measure the template when the steel belt is installed, and nail 3-4 small nails around the same height of the template. Top steel Put the steel belt on the nail when belting, you can keep the installation level of the steel belt). When installing the screws, the tightness of each screw must be consistent, so as to ensure the consistency of the tightness of the steel belt and the safety of construction (installation tips: use the same person to reinforce the screw for the same column). After the formwork is closed and reinforced, the bottom circular plane of the formwork should be 0.5-1cm away from the ground, and the joints should be filled with concrete.

How to protect the cylindrical steel template? Let the technical staff introduce it below:

(1) When hoisting the template, lift it gently and avoid collision to prevent deformation of the template.

(2) Do not use a sledgehammer or crowbar to pry hard when removing the mold, so as not to damage the concrete surface and Lengjiao.

(3) If the removed steel template is found to be uneven or the ribs are damaged or deformed, it should be repaired in time .

(4) Steel molds should be managed during use, stacked according to specifications, and timely repainted to prevent rust Agent.
