The arch skeleton mold is a kind of mold used to make arched skeletons in highways, railways, water conservancy and other projects, which has the advantages of simple structure, convenient operation and fast production. The cast-in-situ arch skeleton mold is an arch skeleton mold that is poured on the construction site, which has higher adaptability and flexibility, and can better meet the needs of the project. This article will introduce the characteristics and manufacturing methods of arch skeleton molds and cast-in-place arch skeleton molds.
First, the characteristics of the arch skeleton mold.
1.Simple structure: The structure of the arch skeleton mold is relatively simple, mainly composed of two semicircular steel templates, which are connected together by bolts and tie rods to form a complete circular mold.
2.Easy to operate: The operation of the arch skeleton mold is relatively simple, you only need to pour concrete into the mold and wait for it to solidify. During operation, attention needs to be paid to maintaining the stability of the mold and preventing concrete leakage.
3.Quick production: The production of arch skeleton mold is relatively fast, and only two semicircular steel templates need to be processed and connected to complete the production. At the same time, this mold can be reused, which improves production efficiency.
Second, the characteristics of cast-in-place arch skeleton mold.
1.Higher adaptability: The cast-in-place arch skeleton mold can be customized according to the engineering needs, and can adapt to different terrain and size requirements, with higher adaptability.
2.Higher flexibility: The cast-in-place arch skeleton mold can be poured on the construction site, which is not limited by transportation and installation, which is more flexible and convenient.
3.Better quality control: The cast-in-place arch skeleton mold can carry out better quality control during the construction process, which can find and solve problems in time to ensure the quality of the project.
Third, the production method of arch skeleton mold and cast-in-situ arch skeleton mold.
1.How to make an arch skeleton mold:
1) Choose the right material: choose high-quality steel, such as Q235 steel or Q345 steel, etc., and process and make it according to the design requirements.
2) Processing semi-circular steel formwork: cut the steel to the required length, and then crimp and weld it to form a semi-circular steel formwork.
3) Processing supports and fixtures: Machining supports and fixtures, such as bolts and tie rods, on the steel formwork.
4) Assembly and commissioning: Assemble and debug the two semicircular steel formwork to ensure that it can work normally.
2.Production method of cast-in-place arch skeleton mold:
1) Design drawings: design according to engineering requirements, determine the shape, size and structure of the mold, etc.
2) Choose the right material: choose high-quality steel, such as Q235 steel or Q345 steel, etc., and process and make it according to the design requirements.
3) Processing steel formwork: cut the steel to the required length and shape, and then crimp and weld it to form the required steel formwork.
4) Processing supports and fixtures: Machining supports and fixtures, such as bolts and tie rods, etc., on the steel formwork.
5) Assembly and commissioning: Assemble and debug all steel formwork to ensure that it can work normally.
Fourth, summary. This paper introduces the characteristics and manufacturing methods of arch skeleton mold and cast-in-situ arch skeleton mold. These two kinds of molds have a wide range of applications in highways, railways, water conservancy and other projects, and have the advantages of simple structure, convenient operation and fast production. At the same time, the cast-in-place arch skeleton mold also has higher adaptability and flexibility, which can better meet the engineering needs. In the production process, it is necessary to select appropriate materials, high processing accuracy, strict assembly and debugging, etc., to ensure the quality and use of the mold.
