Landlord, you are talking about the single curve and hyperbola of the bridge piers!
If the landlord is talking about the single curve and hyperbolic steel formwork of the pier column, the single curve refers to the pier column has only one curve in one direction, and the curve is in one direction, such as the vertical direction, or the horizontal direction.
Hyperbolic pier stud refers to the pier stud in one direction contains two circles, and the two circles are not overlapping, and the direction is inconsistent, such a pier stud is called hyperbola.
Monobolic and hyperbolic are currently the mainstream direction of China's high-speed rail pier design, and their beautiful streamlined appearance is also a trend sought after by many design institutes. But the hyperbolic pier stud steel template is complicated to process, labor-consuming and time-consuming, it is difficult to do the standard in the design data in the arc part of the curve end, basically are approximate shapes, it is easy to make mistakes without paying attention to a little, indirectly increases the cost of steel formwork processing manufacturers, because the hyperbolic steel formwork can only be processed to the approximate shape, causes the arc patchwork panel that has a circle and a circle at the pier cap position, in fact causes the joint on the appearance of the hyperbolic pier stud, and also causes the imperfection of concrete appearance.
Therefore, the design of hyperbolic pier stud is a challenge to the processing technology and processing technology of steel formwork processing manufacturers, originally hoped that the beautiful streamlined appearance would catch people's attention, but in fact caused the imperfection of the arc part of the pier cap, because this kind of pier stud is basically solid, so it caused the waste of materials, and the design of this time-consuming and time-consuming waste of materials has now become the mainstream of the design institute.
To sum up, the purpose of the hyperbolic pier stud is to pursue the streamlined appearance, but in fact, because of the splicing of the arc part of the pier cap, the imperfection of the streamlined appearance has been caused, resulting in the time-consuming and time-consuming steel formwork manufacturers.

The single-line pier stud template refers to the pier stud in one direction and only one curve, and the curve is in one direction, such as the vertical direction, or the horizontal direction, which is the mainstream direction of the current high-speed rail pier stud design in China, and at the same time, because of its beautiful streamlined appearance, it has been sought after by many design institutes; And hyperbolic template refers to the inclusion of two circles in one direction of pier stud, and these two circles are not overlapping, and the direction is inconsistent, therefore, processing is not only complicated, labor-consuming and time-consuming, and it is difficult to do the standard in the design data in the arc part of the curve end, basically are approximate shapes, and it is easy to make mistakes without paying attention to a little, therefore, the cost of steel formwork processing manufacturers will be increased indirectly, and furthermore, compared with single-line pier stud template, the use range of this template is less.

Single Wire Thread: A thread with only one spiral groove on a cylinder is called a single wire thread. >>>More
Generally, it is used to pry with a crowbar, but some of them are fused with concrete for a long time, and finally need to be chiseled down. Otherwise, it will not be possible to continue the decoration unevenly.
The bridge pier abutment is mainly composed of three parts: pier abutment, pier body and foundation. >>>More
Kiss! Hello, happy to answer your <>
The main quality standards and main construction precautions for the construction of pro-bridge piers are as follows: measurement and positioning 1), before the pier body template is assembled, the measurement class should be accurately measured and released; 2) After the completion of the vertical mold, the measurement team should open the Tongran to measure and review the pier body template; The connection part of the cushion cap and the pier body should be chiseled with a pickaxe, and the fresh concrete bedrock surface should be exposed, and the debris or garbage at the bottom must be cleaned up before the vertical mold and the concrete is poured, and the concrete can be poured only after being moistened with water. The reinforcement protective layer cushion block must be provided with the cushion block whose strength, compactness and durability meet the requirements of high-performance concrete on the pier body reinforcement, and the size of the cushion block should meet the design and specification requirements, and be completed before the formwork is installed. >>>More
Cushion cap: refers to the reinforced concrete platform that connects the top of each pile arranged at the top of the foundation pile in order to bear and distribute the load transmitted by the pier body. >>>More
