Description

Technical Field

[0001] This invention relates to the field of seamless construction technology for ultra-long concrete structures, and specifically to a quick-assembly mold for seamless construction of ultra-long concrete structures. Background Technology

[0002] In the construction of ultra-long concrete structures, to achieve seamless pouring, it is essential to ensure the precision and tightness of the splicing between adjacent molds to prevent problems such as grout leakage and mold deformation during pouring. Traditional mold splicing often uses bolt connections, which are not only cumbersome and time-consuming to install, but also require repeated calibration during positioning, making it difficult to quickly achieve precise multi-point fixing. Furthermore, the stress on the molds during tightening cannot be monitored in real time, easily leading to mold deformation due to uneven stress, thus affecting the quality of concrete pouring. In addition, the replacement process for components such as steel wire ropes used for tightening and fixing in traditional molds is complex after wear, requiring the disassembly of numerous auxiliary structures, which can easily affect the construction progress and may even damage the already spliced ​​mold structure.

[0003] To address the aforementioned issues, the existing technology lacks a quick-assembly mold that can be rapidly assembled, precisely positioned, monitor stress in real time, facilitate component replacement, and effectively prevent mold deformation. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a quick-assembly mold for seamless construction of ultra-long concrete structures.

A pressure scale monitors the screw pressure in real time, indirectly reflecting the steel wire rope tension. Data is displayed intuitively on a screen, allowing workers to promptly identify problems such as loose or worn steel wire ropes and perform maintenance in advance, preventing component failures from affecting construction safety and quality. Adjustable screw, threaded sleeve, and second piston cylinder allow for precise control. The top block position is adapted to the locking requirements of molds at various angles, such as at bends. By changing different arc-shaped top blocks, it can meet the needs of various construction scenarios, making it widely versatile. When the wire rope wears out, it can be quickly removed and replaced with a new wire rope under the premise of temporary support of the stabilizing frame, without the need to disassemble a large number of structures. The operation is simple, and the hydraulic stabilizing structure reduces the wear of the screw assembly, extends the service life of the components, and reduces maintenance costs. The triangular support structure formed by the reinforcing rod and the stabilizing rod enhances the rigidity of the bearing rod. The hydraulic oil circuit fixing structure prevents the screw assembly from loosening. The multi-point support formed by the top block and the semi-circular support plate disperses the force on the mold, effectively preventing mold deformation and ensuring the quality of concrete pouring.

[0030] An oil inlet pipe is fixedly installed at the top of the oil cylinder 15, and a valve is installed on the oil inlet pipe to control the oil inlet of the oil cylinder 15.

[0031] Two second piston cylinders 24 are fixedly installed on one side wall of the bearing plate 14. A second piston rod 30 is slidably connected inside each second piston cylinder 24. A fixing plate 29 is fixedly installed at one end of each second piston rod 30. A threaded sleeve 28 is fixedly connected between the two fixing plates 29.

[0032] A top block 31 is provided on one side of the threaded sleeve 28. An insertion hole 32 is provided on the side wall of the top block 31. The threaded sleeve 28 is inserted into the insertion hole 32 and slidably connected with it. A groove is provided on the top block 31. Inclined portions are provided at the top and bottom of the top block 31. Extrusion rubber is fixedly installed on the side wall of the top block 31 where it fits with the mold 1. The side wall of the mold 1 is respectively fitted with the corresponding inclined portion of the top block 31. The wire rope 8 passes through the groove and slidably connected with it. The top and bottom of the top block 31 are provided with 30° inclined portions. An extrusion rubber with a thickness of 5mm is fixed at the fitting point.

[0033] The top of the connecting frame 2 is provided with a second positioning hole 35, the top of the top block 31 is provided with a first positioning hole 34, and a stabilizing frame 33 is provided directly above the two semi-circular support plates 5. The stabilizing frame 33 is T-shaped, and positioning rods 36 are fixedly connected to the bottom of the three side ends of the stabilizing frame 33.

The diameter of the positioning rod 36 is 11.8mm, and it is clearance-fitted with the first positioning hole 34 and the second positioning hole 35.

[0034] The semi-circular support plate 5 has limit grooves 37 at both ends. Each connecting frame 2 has a limit rod 38 fixedly installed on its side wall. Each limit rod 38 extends into the corresponding limit groove 37 and is slidably connected to it. Two baffles 39 are fixedly installed on the outer wall of each connecting frame 2. A balance plate 40 is fixedly installed between the arc-shaped inner walls of the semi-circular support plate 5. The balance plate 40 is inserted between the two sets of baffles 39 and is slidably connected to them. Each set of baffles 39 is located below the wire rope 8. Dovetail grooves 42 are symmetrically arranged on the balance plate 40. A dovetail block 43 is slidably connected in each dovetail groove 42. A detector 41 is fixedly installed at the top of each dovetail block 43. A partition 48 is fixedly installed in the detector 41. A slidably connected part is inserted into the partition 48. A T-shaped rod 45 has a contact rod 44 fixedly connected to one end. One end of the contact rod 44 is semi-circular and passes through and slides through the detector 41. A display screen is mounted on the top of the detector 41. A spring 49 is sleeved on the T-shaped rod 45. A resistor block 47 is fixedly mounted on one side wall of the partition 48. A conductive sheet 46 is fixedly mounted on one end of the T-shaped rod 45, with one side of the conductive sheet 46 fitting against the side wall of the resistor block 47. A battery is fixedly mounted on the inner wall of one side of the detector 41. The positive terminal of the battery is electrically connected to the conductive sheet 46 via a wire, and the negative terminal of the battery is fixedly connected to one end of the resistor block 47 via a wire. The display screen is electrically connected to the battery via a wire. Furthermore, during installation, a limit groove 37 and a limit... Positioning rod 38 effectively limits the position of the semi-circular support plate 5 and the connecting frame 2, ensuring they are on the same plane. This facilitates the positioning of the top block 31. After installation, it further limits the position of the semi-circular support plate 5 and the connecting frame 2, keeping them horizontal. Two sets of baffles 39 and balance plates 40 are provided, ensuring that the wire rope 8 is on the parallel plane of the semi-circular support plate 5 and the connecting frame 2. When the wire rope 8 is taut, if it is tilted to the horizontal plane, a component force will appear in the direction of the force on the two connecting frames 2 after tension (tilting to the horizontal plane will result in an upward or downward component force). This will cause an imbalance of force at the joint of the two molds 1 (i.e., the top or bottom of the two molds 1 will be uneven). (Slight V-shaped deformation occurs), affecting subsequent sealing. After further limiting the baffle 39 and balance plate 40, a detector 41 is set. After tightening, the sliding detector 41 is equipped with a dovetail groove 42 and a dovetail block 43 to ensure the stability of the sliding. The touch rod 44 contacts the side of the baffle 39. If the current fluctuation displayed on the detector 41 is within the stable range (consistent with the surface roughness of the baffle 39), it indicates that the forces on both sides are balanced and the contact surfaces of the two molds 1 maintain a good sealing effect. If the fluctuation range is unstable (the sliding of the conductive sheet 46 to the touch rod 44 causes the conductive sheet 46 to move as well, changing the contact position with the resistor block 47, thereby changing the displayed current, which is similar to the principle of a sliding rheostat).This prompts the operator to make fine adjustments. These adjustments involve the threaded sleeve 28 and the adjusting screw 27. First, the second control valve 26 is opened, allowing the threaded sleeve 28 and adjusting screw 27 to be adjusted. Based on the change in current from the detector 41, the forward and backward movement of the threaded sleeve 28 is adjusted to achieve fine-tuning and ensure a good seal between the contact surfaces of the two molds 1.

[0035] Working Principle: First, place two U-shaped molds 1 at the preset construction position, aligning the splicing ends of the two molds 1 to ensure a seamless splicing foundation. Then, place a semi-circular support plate 5 on one side of the two molds 1, ensuring both ends of the semi-circular support plate 5 are flush with the inner wall of the mold 1. Insert locking pins through the mounting holes on the mounting block 19 to fix the semi-circular support plate 5 to the ground, preventing displacement during subsequent operations. Next, thread the wire rope 8 through the first through groove 3 on the connecting frame 2 of the two molds 1 and the second through groove 7 on the semi-circular support plate 5, ensuring the outer wall of the wire rope 8 is flush with the outer arc walls of the first guide block 4 and the second guide block 6, reducing friction and wear on the wire rope 8. Fix lifting rings 9 to both ends of the wire rope 8, engaging the lifting rings 9 in the slots 23 of the bearing rod 13, and positioning them between the limiting block 22 and the stabilizing rod. The engagement of the slots 23, the limiting block 22, and the stabilizing rod restricts the displacement of the lifting rings 9.

[0036] Using an electric wrench to rotate the lead screw 11, the lead screw 11 drives the lead screw assembly 12, which is threaded to it, to move axially along the lead screw 11. The bearing rods 13 on both sides of the lead screw assembly 12 move together, thereby pulling the steel wire rope 8 through the lifting ring 9. Since the steel wire rope 8 is limited and guided by the first through groove 3 and the second through groove 7, the tension can be accurately transmitted to the two connecting frames 2, causing the two molds 1 to move closer to each other and achieve a tight splicing. In this process, the triangular support structure formed by the reinforcing rod 21 and the stabilizing rod can enhance the rigidity of the bearing rod 13 and prevent the bearing rod 13 from bending and deforming under force; the limiting block 22 further strengthens the connection between the reinforcing rod 21 and the bearing rod 13, avoids relative displacement between the two, and ensures stable transmission of tension.

[0037] As the bearing rod 13 moves, the first piston rod 20, which is fixedly connected to its side wall, moves together with the bearing rod 13, causing the first piston rod 20 to slide inside the first piston cylinder 16. Hydraulic oil flows from the oil cylinder 15 through the first oil pipe 17 into the first piston cylinder 16. When the pressure value displayed on the pressure scale 10 reaches the preset range, it indicates that the tension of the wire rope 8 meets the mold fixing requirements. The rotation of the lead screw 11 is stopped, the first control valve 18 is closed, and the hydraulic oil circuit where the first oil pipe 17 is located is disconnected. Since hydraulic oil is incompressible, the position of the first piston rod 20 is fixed, thereby restricting the rotation of the lead screw 11 through the bearing rod 13 and the lead screw assembly 12, preventing the lead screw assembly 12 from being disengaged or loosened due to long-term stress, and achieving long-term stable fixing of the mold.

[0038] During the pouring process after the mold is fixed, the pressure scale 10 continuously monitors the pressure on the lead screw 11 and displays the value in real time on the screen. Since the pressure on the lead screw 11 corresponds to the tension of the wire rope 8, the operator can judge the tension status of the wire rope 8 by the pressure value. When the pressure value remains stable, it indicates that the tension of the wire rope 8 is normal and the mold is reliably fixed; when the pressure value drops, it indicates that the wire rope 8 may be loose or worn, and the tension is insufficient. It is necessary to check and maintain the wire rope 8 in time to avoid gaps at the mold joints that could lead to grout leakage or mold deformation.

[0039] When the construction location is a bend and the multi-angle mold 1 needs to be locked, first replace the arc-shaped top block 31 with one that matches the bend angle of the mold 1, and fit the top block 31 onto the threaded sleeve 28 through the insertion hole 32. Open the second control valve 26 to allow the hydraulic oil in the oil cylinder 15 to flow into the second piston cylinder 24 through the second oil pipe 25. Rotate the adjusting screw 27 to move the fixing plate 29 and the threaded sleeve 28, and precisely adjust the distance between the top block 31 and the inner wall of the mold 1 so that the inclined part of the top block 31 fits tightly against the side wall of the mold 1.

[0040] The extruded rubber on the top block 31 increases the friction between it and the mold 1, improving the fixing effect. Simultaneously, the inclined portion of the top block 31 guides the mold 1 to automatically achieve further alignment and positioning. At this point, the top block 31 and both ends of the semi-circular support plate 5 form a multi-point support structure. Compared to traditional bolt connections, no deliberate calibration is required, making installation quick and convenient. Furthermore, the multi-point support disperses the force on the mold 1, effectively preventing deformation and reducing the number of subsequent mold support components, thus lowering construction costs. After adjustment, the second control valve 26 is closed, and the position of the second piston rod 30 is fixed to ensure the stability of the threaded sleeve 28 and the adjusting screw 27, preventing disengagement or loosening.

[0041] When the wire rope 8 becomes loose or unreliable due to prolonged and repeated use and frictional wear, the pressure index of the pressure scale 10 will decrease. At this time, the stabilizer 33, through the cooperation of the positioning rod 36 with the first positioning hole 34 and the second positioning hole 35, temporarily supports the top block 31 and the semi-circular support plate 5, preventing the mold 1 from deforming or shifting and ensuring construction safety. Subsequently, the operator opens the first control valve 18 to open the hydraulic oil circuit, releases the hydraulic oil from fixing the first piston rod 20, pulls out the two limit blocks 22, loosens the screw 11, and causes the screw assembly 12 to drive the bearing rod 13 to move in the opposite direction, loosening the wire rope 8. The two lifting rings 9 are pulled out from the slots 23 of the bearing rod 13, and the worn wire rope 8 is pulled out from the first through slot 3, the second through slot 7 and the groove of the top block 31, and a new wire rope 8 is replaced.

[0042] After the new steel wire rope 8 is installed, following the operating procedures of the mold splicing and fixing stage, retighten the steel wire rope 8, close the first control valve 18, fix the hydraulic oil circuit, and remove the stabilizer 33. The stabilizer 33 can be retained or removed, as it also serves as auxiliary support, thus completing the rapid replacement of the steel wire rope 8. The entire replacement process does not require the disassembly of a large number of auxiliary structures, making the operation convenient and quick, and will not damage the already spliced ​​mold 1 or construction structure, ensuring that the construction progress is not affected.
