Introduction of cylindrical steel formwork
Cylindrical steel formwork is an important building formwork, which is widely used in bridges, construction, water conservancy and other engineering fields. Due to its excellent mechanical properties and durability, cylindrical steel formwork has gradually become the preferred formwork in modern building construction. This article will introduce the characteristics, advantages, usage methods and precautions of cylindrical steel formwork in detail.
First, the characteristics of cylindrical steel formwork.
The cylindrical steel formwork is made of high-quality steel plate material, which is precision machined and has the following characteristics:
1.High strength: The cylindrical steel formwork has high compressive and flexural strength, which can withstand large lateral pressure and ensure the stability in the concrete pouring process.
2.Good durability: The cylindrical steel formwork is made of high-quality materials, which has a long service life and can be reused many times, reducing the project cost.
3.High processing accuracy: The cylindrical steel formwork adopts advanced processing technology, with high dimensional accuracy and few splicing joints, which can effectively ensure the appearance quality of the cylindrical after molding.
4.Fast demoulding speed: The special design of the cylindrical steel formwork makes the demoulding speed fast, which can greatly shorten the construction period and improve the construction efficiency.
5.Environmental protection and energy saving: cylindrical steel formwork can be recycled to reduce waste pollution to the environment, and at the same time, energy-saving technology is adopted in the production process to reduce energy consumption.
Second, the advantages of cylindrical steel formwork.
Compared with traditional wood molds and plastic molds, cylindrical steel formwork has the following advantages:
1.Strong bearing capacity: The cylindrical steel formwork has a high bearing capacity, which can effectively resist the lateral pressure when pouring concrete and ensure the safety of construction.
2.Wide range of application: Cylindrical steel formwork can be customized according to different diameter and height requirements, with a wide range of application to meet various engineering needs.
3.Good stability: The cylindrical steel formwork adopts an integral design, which has good stability and is not easy to deform, which can ensure that the cylindrical shape after forming is regular.
4.Easy to operate: The cylindrical steel formwork is easy to assemble and simple to operate, which can greatly reduce the labor intensity of workers and improve construction efficiency.
5.Cost reduction: The cylindrical steel formwork can be recycled, which reduces the cost of materials and waste disposal, and at the same time improves the construction efficiency and reduces the labor cost.
Third, the use of cylindrical steel formwork.
When using cylindrical steel formwork, the following steps need to be followed:
1.Preparation: Select the appropriate cylindrical steel formwork according to the engineering requirements, check the quality of the formwork, and ensure that there is no damage and no deformation. The template is treated with rust removal and release agent.
2.Assembling formwork: Assemble the cylindrical steel formwork into a whole according to the construction drawings to ensure the accuracy and stability of assembly. Pay attention to adjusting the joints between the formwork to prevent slurry leakage when pouring concrete.
3.Installation and fixation: fix the assembled cylindrical steel formwork in a predetermined position to ensure that the formwork is stable and does not sink. Scaffolding, tie rods and other tools can be used to fix the formwork.
4.Concrete pouring: Pouring concrete in the cylindrical steel formwork, pay attention to controlling the pouring speed and vibration mode of the concrete, and prevent the concrete from causing excessive lateral pressure on the formwork.
5.Mould removal and curing: After the concrete reaches a certain strength, the cylindrical steel formwork is dismantled block by block in order. Pay attention to protect the concrete surface and carry out curing in time.
6.Cleaning and maintenance: After each use, the cylindrical steel formwork is cleaned and maintained, and anti-rust paint is painted to prevent rust and deformation. Repair or replace damaged templates.
4. Precautions.
In the process of using cylindrical steel formwork, the following matters need to be noted:
1.According to the engineering requirements, select the appropriate cylindrical steel formwork specifications and quantities to avoid waste and insufficiency.
