Abstract
Description
Technical Field
[0001] This invention belongs to the field of building construction technology, and in particular relates to a large steel formwork construction system and method based on multi-angle leveling and top monitoring. Background Technology
[0002] In the construction of cast-in-place concrete columns, large steel formwork is widely used because of its high rigidity, high turnover rate, and good concrete forming quality. The flatness and verticality of the formwork installation directly determine the construction quality, appearance, and structural safety of the concrete column. Traditionally, the leveling of large steel formwork relies on manual labor using tools such as crowbars, steel wire ropes, and hoists, along with plumb lines and straightedges. However, the applicant discovered the following drawbacks of the existing construction methods: (1) Inefficient: The adjustment process is cumbersome, requires the cooperation of many people, and takes a long time; (2) Poor precision: It relies on workers' experience, has large human error, and is difficult to control precisely to the millimeter level; (3) Low safety: There is a certain safety risk when operators operate under or to the side of the template; (4) Weak coordination: Verticality and flatness adjustment are often carried out separately, making it difficult to achieve synchronous and efficient adjustment. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art by providing a large steel formwork construction system and method based on multi-angle leveling and top monitoring. This system achieves integrated and synchronized adjustment of flatness and verticality, reducing the work that originally required several hours to be completed by a single person within ten minutes, significantly improving construction efficiency. At the same time, it ensures the forming quality of the concrete column, and the operators do not need to perform heavy physical leveling work in dangerous areas, thus reducing safety risks.
[0004] The objective of this invention is achieved through the following technical solution: A large steel formwork construction system based on multi-angle leveling and top monitoring includes a large steel formwork and reinforcing back ribs installed on the large steel formwork. The large steel formwork is used to form the main formwork of a concrete column. The reinforcing back ribs are hinged with multiple leveling rods extending vertically. An electronic tube level is installed on the top of the large steel formwork, and a verticality sensor is installed on the side of the large steel formwork. Both the electronic tube level and the verticality sensor are electrically connected to a control device.
[0005] In one embodiment, at least one leveling rod is hinged to each of the four corners of the reinforcing back rib.
[0006] In one embodiment, each of the leveling rods is independently connected to the control device.
[0007] In one embodiment, one end of the leveling rod is hinged to the reinforcing back brace, and the other end is supported on the ground structure.
[0008] In one embodiment, the leveling rod is an electric leveling hydraulic rod.
[0009] In one embodiment, a load-bearing base plate is also provided at the bottom of the large steel formwork.
[0010] This invention also provides a large steel formwork construction method based on multi-angle leveling and top monitoring, and based on the above-mentioned large steel formwork construction system, it includes: In the initial installation phase, the large steel formwork was hoisted and initially positioned. During the leveling stage, the leveling is carried out using an electronic tube level, a verticality sensor, and a leveling rod until the horizontality and verticality of the large steel formwork both reach the set threshold. During the pouring stage, concrete is poured.
[0011] In one implementation, the leveling stage further includes: Acquire initial data from the vacuum tube level and the verticality sensor; Calculate the required expansion / contraction amount for each leveling bar; Each leveling bar is driven to extend and retract independently according to its own required extension and retraction amount.
[0012] In one implementation, the leveling stage further includes: The system collects real-time data from the electronic tube level and verticality sensor during the movement of the leveling rod, and repeatedly calculates the required expansion and contraction for each leveling rod, driving the leveling rod to move until the horizontality and verticality of the large steel formwork both reach the set threshold. In one implementation, the thresholds are set as horizontal error ≤ 2 mm and vertical error ≤ 3 mm.
[0013] The beneficial effects of this invention are as follows: (1) It realizes the integrated and synchronized adjustment of flatness and verticality, solves the problem of traditional methods of separate adjustment and mutual interference, and provides underlying technical support for intelligent construction.
[0014] (2) By adopting hydraulic servo control and electronic sensing technology, the adjustment accuracy is improved from centimeter level to millimeter level, which greatly improves the forming quality of concrete columns.
[0015] (3) Automated adjustment has replaced a large amount of manual work, reducing the work that originally required several people and hours to be completed by a single person within ten minutes, which has significantly improved construction efficiency.
[0016] (4) Operators are not required to perform heavy physical leveling work in dangerous areas, which reduces safety risks. Attached Figure Description

[0019] The invention will now be further described with reference to the accompanying drawings.
[0020] This invention provides a large steel formwork construction system based on multi-angle leveling and top monitoring, such as... Figures 1 to 3 As shown, it includes a large steel formwork 1 and a reinforcing back rib 2 set on the large steel formwork 1. The large steel formwork 1 is used to form the main formwork of the concrete column. The reinforcing back rib 2 is hinged with multiple leveling rods 3 extending in the vertical direction. An electronic tube level 4 is set on the top of the large steel formwork 1. A verticality sensor 5 is also set on the side of the large steel formwork 1. The electronic tube level 4 and the verticality sensor 5 are both electrically connected to the control device. In this embodiment, as Figure 2 As shown, at least one leveling rod 3 is hinged to each of the four corners of the reinforcing back rib 2; Furthermore, each leveling rod 3 is independently connected to the control device. One end of the leveling rod 3 is hinged to the reinforcing back rib 2, and the other end is supported on the ground structure. In this embodiment, the leveling rod 3 is an electric leveling hydraulic rod, so that the extension and retraction stroke can be precisely controlled by the control device; It should be noted that in this embodiment, the large steel formwork 1 serves as the main formwork constituting the concrete column forming surface. The reinforcing back ribs 2 are used to reinforce the formwork and provide structural support, ensuring that the formwork will not deform or shift when subjected to the lateral pressure of concrete, thereby guaranteeing the dimensional accuracy and surface flatness of the component. The reinforcing back ribs 2 are arranged horizontally or vertically, sharing the force with the large steel formwork 1, effectively improving the overall rigidity and load-bearing capacity of the formwork system and preventing "formwork bulging" or "formwork running away" phenomena. The number of leveling rods 3 is at least four, respectively arranged at the four corners of the reinforcing back ribs 2, and the leveling rods 3 at the four corners are independently controlled, that is, the torsion and tilt of the formwork are corrected through different differential expansion and contraction. The electronic tube level 4 is set on the top of the large steel formwork 1. The horizontal state (i.e., flatness) of the top of the template is monitored in real time, and the verticality sensor 5 set on the side of the large steel template 1 is used to monitor the vertical state (i.e., verticality) of the side of the template in real time. That is, the electronic tube level 4 located on the top of the large steel template 1 and the verticality sensor 5 located on the side of the large steel template 1 work together to realize the integrated and synchronized adjustment of flatness and verticality. This solves the problem of separate adjustment and mutual interference in the traditional method. Moreover, the automated adjustment by the control device replaces a lot of manual work, shortening the work that originally required several hours to be completed by a single person within ten minutes, which significantly improves the construction efficiency. At the same time, the use of hydraulic servo control and electronic sensing technology improves the adjustment accuracy from centimeter level to millimeter level, which greatly improves the forming quality of concrete columns.
[0021] In one embodiment, a load-bearing base plate is also provided at the bottom of the large steel formwork 1.
[0022] This invention also provides a large steel formwork construction method based on multi-angle leveling and top monitoring, and based on the above-mentioned large steel formwork construction system, it includes: In the initial installation phase, the large steel formwork was hoisted and initially positioned. During the leveling stage, the leveling is carried out using an electronic tube level, a verticality sensor, and a leveling rod until the horizontality and verticality of the large steel formwork both reach the set threshold. During the pouring stage, concrete is poured.
[0023] Specifically, the leveling phase also includes: Acquire initial data from the vacuum tube level and the verticality sensor; Calculate the required expansion / contraction amount for each leveling bar; Each leveling bar is driven to extend and retract independently according to its own required extension and retraction amount; The system collects real-time data from the electronic tube level and verticality sensor during the movement of the leveling rod, and repeatedly calculates the required expansion and contraction for each leveling rod, driving the leveling rod to move until the horizontality and verticality of the large steel formwork both reach the set threshold. The thresholds are set as follows: horizontal error ≤ 2mm and vertical error ≤ 3mm.
[0024] It should be noted that after the large steel formwork is initially hoisted into place, the leveling stage can be initiated. The control device reads the initial data from the electronic tube level and vertical sensor, and the built-in algorithm of the control device calculates the required extension and retraction of each leveling rod at the four angles (if the left side needs to be leveled, the two hydraulic rods on the left side are instructed to lift synchronously by a certain stroke; if the front or rear tilt needs to be corrected, the hydraulic rods on the front or rear side are instructed to make differential adjustments). The system monitors and provides feedback data in real time, forming a closed-loop control until both the horizontal and vertical alignments reach the set thresholds. Then, the system issues a prompt sound to indicate that the leveling is complete. Automated adjustment replaces a large amount of manual work, reducing the work that originally required several hours to be completed by a single person within ten minutes, significantly improving construction efficiency. Operators no longer need to perform heavy physical leveling work in dangerous areas, reducing safety risks. Finally, workers can conduct a final inspection and tighten other auxiliary supports before concrete pouring can begin.
