Price of CNC tensioning system for beam field
Application : can set the target value of tensile force, target value of displacement check, holding time, etc. The tension is synchronized and balanced during tensioning. The pressure and displacement sensors collect data in time to simulate and convert the digital display of the tension value and the tensile length of the steel strand. The computer automatically calculates the elongation and timely checks whether the elongation error is within 6%. To achieve "double control" of stress and elongation, the continuous in-situ cast-in-situ box girder steel strands automatically reach the recorded value after the extension reaches the top. (Section 7.6.3 of the construction code for highway bridges and culverts stipulates that "When the prestressed tendons are tensioned using the stress control method, the elongation should be checked .... The deviation should be controlled within 6%.) Standard tensioning process: prestressing The system realizes the intelligent control of the prestressed tensioning program, which is not affected by man-made and environmental factors; the tensioning process elements such as the stopping point, loading rate, and holding time meet the requirements of the bridge design load construction specification, avoiding or greatly increasing the tensioning process Loss of prestressing.

Shelf life : The common treatment methods are: pull out the steel wire stranded with a jack, take out the old clip, replace it with a new clip, and then use the jack to tension to the design requirements. The intelligent tensioning device checks whether the wire is broken after tensioning, and analyzes the main reasons for the following two kinds of wire breakage: ① The steel strands are tangled with each other and the force is uneven, which causes the individual steel strands to be pulled too much, and the wire is pulled. Broken wire phenomenon; ② steel strands suffered mechanical damage during transportation. If the number of broken wires exceeds the design range, it should be treated. The specific treatment method: Generally use a jack to unload all the strands, replace them with new strands, and re-stretch the bundles. After tensioning is completed, in order to prevent the loss of prestress, the grouting work must be completed within 48 hours. Operators of intelligent tensioning equipment should comply with relevant national safety regulations when conducting high-altitude, electrical and hydraulic equipment. In addition, the following points should be paid attention to: (1) Because the non-bonded prestressed tendons have great flexibility, the construction personnel When laying high-altitude non-adhesive tendons, the prestressed tendons should be prevented from bouncing and hurting people.

The following editors will introduce you to bridge prestressed intelligent tensioning equipment manufacturers, and solve some unnecessary troubles for you. Due to the domestic economic development, the extension of the route has begun to develop. Nowadays, the construction team is also getting busier. In many bridge construction and highway construction, inverted mechanized equipment will be used, which not only saves time and effort, but also Precise and reassuring. One of them is the bridge prestressed intelligent tensioning device, which helps a lot when prestressing the anchor. After trying the benefits of bridge prestressing tensioning equipment, many construction teams have the intention to purchase tensioning equipment, but because of the rigorous construction needs, there are still many concerns. If you want a good bridge prestressing intelligent tensioning equipment, Need to get a good prestressing manufacturer, today I will recommend a better bridge prestressing intelligent tensioning equipment manufacturer, I hope to help you. The editor of the bridge prestressed intelligent tensioning equipment recommended by Xiaobian is located in Hefei, one of the domestic manufacturers of prestressed equipment. In addition, grounding is very important in actual engineering. If the grounding is not well solved, the signal will be unstable. At this time, the signal instability cannot be solved by software filtering. In actual engineering, various ground wires should be connected according to regulations. It should be noted that the negative signal terminal of the signal input terminal of the EM235A / D module should be connected with the ground wire. What are the conditions for pre-tensioning, pre-tensioning, and final tensioning: When the concrete strength of the beam reaches 50% of the planned strength, pre-tensioning can be performed. The formwork should be loosened and should not prevent the beam from contracting. Tension quantity, orientation and tension value should meet the planning requirements. ⑵Conditions for initial tension: When the concrete strength of the beam body reaches 80% of the planned strength level specification value and the concrete is placed for 96 hours, the initial tension can be performed. The beam can only be lifted off the stand after the initial tension. Tension quantity, orientation and tension value should meet the planning requirements. When the beam strength reaches 80% of the planned strength during demolding, the two stages of pretensioning and initial tensioning are combined into one stage for construction.

The following editors will introduce you to bridge prestressed intelligent tensioning equipment manufacturers, and solve some unnecessary troubles for you. Due to the domestic economic development, the extension of the route has begun to develop. Nowadays, the construction team is also getting busier. In many bridge construction and highway construction, inverted mechanized equipment will be used, which not only saves time and effort, but also Precise and reassuring. One of them is the bridge prestressed intelligent tensioning device, which helps a lot when prestressing the anchor. After trying the benefits of bridge prestressing tensioning equipment, many construction teams have the intention to purchase tensioning equipment, but because of the rigorous construction needs, there are still many concerns.

The editor of the bridge prestressed intelligent tensioning equipment recommended by Xiaobian is located in Hefei, one of the domestic manufacturers of prestressed equipment. In addition, a large number of force sensors embedded in the prestressed structure cannot be reused after construction, increasing the cost of the building. On the other hand, the data collection and processing in the construction process are completed by computer. Obviously, this has higher requirements for the quality of prestressed construction personnel. Prestressed digital intelligent tensioning equipment overcomes many problems existing in traditional prestressed construction technology, and has the following characteristics: ①High accuracy. It can guarantee the tensile accuracy in the range of 1%, which greatly improves the tensile accuracy compared with the conventional prestressed construction process. It can well ensure the design intent, and effectively avoid the engineering accident of the prestressed structure caused by the uncontrollable tensile tension and pretensioned tensile length. ② Efficiency. The tensioning process is digitalized, reducing the construction staff from 5 to 2. It can overcome the inefficient factors of manual operation and make the construction quick and easy. ③ Double synchronous control of prestressed tension can be realized. On-site monitoring of the effective tensile force on site shows that in a prestressed frame structure, periodic fluctuations in ambient temperature will cause changes in the effective prestress in the prestressed members, and the fluctuation of the effective prestress exceeds the allowable deviation value of 5% in the current code. There is a clear correlation between prestress and ambient temperature and concrete temperature. Therefore, the effect of temperature effects must be considered in the construction of prestressed intelligent tensioning equipment.

First of all, the characteristics of the anchor must be as follows: First, to ensure the rationality of the tensioning process. When using the prestressed anchor, generally, personnel will perform the test tension. Because what the person has to do is to confirm the rationality of the tensioning process, the tensioning of the prestressed anchorage is normal and no harmful cracks appear, so that the batching can be performed in batches. Steel stranded wire stringing machine is also called: steel stranded wire stringing machine, steel stranded wire stringing machine, steel stranded wire tube machine. The stranding machine (pre-stressed stranded wire penetration hole for short) is driven by a mechanical transmission. The rollers hold the stranded wire for transmission. It can be forwarded, retracted, continuously transmitted, and can also be transmitted manually. It conveys the speed of the stranded wire with stepless speed regulation, convenient operation, reliable performance and significant efficiency. The prestressed stranded wire beam passing machine greatly reduces labor intensity. The prestressed stranded wire beam passing machine is widely used in large bridges and box beams. And structures. The whole process does not require manual intervention, and has tension control such as error correction, data synchronization, and tension review. The core is to control the tension construction by computer based on the prestressed tension control and construction summary. The oil pump is operated to perform the tensioning operation, which truly realizes the synchronization control of the tensioning. The company's pre-stressed intelligent tensioning and large-cycle intelligent grouting rely on computers for intelligent operations to realize automatic operation of equipment, which can solve the adverse effects of human factors in key pre-stressed construction processes, and effectively guarantee pre-stressed construction, which has a great construction level And efficiency, ensuring prestressed structure and durability, saving resources and protecting.
