Description

Technical Field

[0001] This invention relates to the field of construction connector technology, specifically to an adjustable elevation combination connector for pier columns. Background Technology

[0002] In the construction of urban underpasses, bridges, and waterfront municipal projects, concrete platforms, steel structure supports, and formwork systems are often required to be erected on the upper part of the piers. Traditional construction methods generally use fixed clamps, welded steel sections, and direct bolt fixing. In waterfront projects in areas with strong tides and frequent typhoon impacts, such as landscape renovation and upgrading projects, the construction of concrete platforms involves multi-segment segmented operations, and the pier support system needs to be frequently adjusted in elevation, quickly disassembled and reassembled, and repeatedly reused.

[0003] However, in the existing technology, most traditional pier column connectors are fixed integrated structures without vertical lifting, threaded adjustment, or sliding lifting mechanisms. After installation, the height is completely fixed and cannot be fine-tuned. The support height can only be changed by adding or removing steel plates, rubber pads, or steel shims. However, the thickness of traditional shims is fixed, commonly 5mm, 10mm, or 20mm, resulting in large deviations in support elevation. This can cause unevenness and inconsistent thickness of the concrete platform bottom, thus affecting the quality and appearance of the pier column structure.

[0004] Therefore, we propose an adjustable elevation combination connector for pier columns to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an adjustable elevation combination connector for piers, so as to solve the problem mentioned in the background art that the low elevation adjustment accuracy of current pier connectors affects the quality of the pier structure.

[0011] Preferably, the concrete pier is provided with a clamping assembly on its exterior, the clamping assembly including a first arc-shaped clamp and a second arc-shaped clamp, and the first arc-shaped clamp and the second arc-shaped clamp are combined to form a ring clamp.

[0012] Preferably, the clamp assembly further includes two locking mechanisms, each locking mechanism comprising a locking pin and a locking buckle. The locking pin is fixedly installed at the end of the first arc-shaped clamp, and the locking buckle is fixedly installed at the end of the second arc-shaped clamp. The locking buckle is inserted inside the locking pin.

[0013] Preferably, multiple locking racks are symmetrically fixedly connected to the inner walls of both sides of the locking pin. A pull-out groove is formed on one outer surface of the locking pin. Movable grooves are formed on both inner walls of the pull-out groove. A movable plate is movably connected inside the pull-out groove. A pull-out rod is fixedly connected to one outer surface of the movable plate, and the pull-out rod corresponds to and matches one outer surface of the locking pin.

[0015] Preferably, the two load-bearing seats are respectively fixedly installed on the outer surfaces of the first arc-shaped hoop and the second arc-shaped hoop.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. During use, by starting the bidirectional synchronous motor, its two output shafts drive the two adjusting screws to rotate simultaneously, driving the two adjusting frames to move outwards at the same time. Through the sliding of the wedge block inside the adjusting groove, the connecting plate, fixed side plate and support frame are pressed down simultaneously, thereby tightening the steel wire rope. The whole system plays an auxiliary role in increasing the tension. By activating the multi-stage hydraulic rod, the height adjustment base is used to lift the main load-bearing beam upwards, thereby completing the high-precision height adjustment operation. This solves the problem that the low height adjustment accuracy of the current pier column connectors affects the quality of the pier column structure.

[0018] 2. During use, the first and second arc-shaped hoops are installed by simultaneously inserting the two locking pins into the two locking buckles. This allows for quick and tight installation of the hoops on the outside of the concrete pier column, offering the advantage of convenient installation. During disassembly, the positioning rod is pulled out of the positioning slot and sliding hole, separating the movable plate from the locking pins. Then, the pull rod is pulled outwards, causing the movable plate to be pulled outwards. At the same time, the locking plate rotates around the center of the rotating rod and slides from the movable slot into the pull slot. At this point, the locking action between the locking buckles and the locking pins is eliminated, allowing for quick separation of the first and second arc-shaped hoops, thus providing the advantage of quick removal of the hoops.

[0019] 3. During use, the height of the adjustable base is adjusted by raising and lowering the multi-stage hydraulic rods. At this time, the stabilizing rod slides inside the limit hole, which can ensure that the adjustable base remains stable during the elevation adjustment and avoid left and right deviation. The bottom ends of the two stabilizing rods are connected by the reinforcing block, which can enhance the sturdiness of the two stabilizing rods. In addition, the reinforcing block improves the sturdiness of the load-bearing base installation. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 11 This invention provides a technical solution: an adjustable-elevation combined connector for piers, comprising a pier assembly 1, a load-bearing assembly 2, an auxiliary adjustment assembly 3, and an adjustment assembly 5. Two adjustment assemblies 5 and two auxiliary adjustment assemblies 3 are provided. Each auxiliary adjustment assembly 3 includes a bidirectional synchronous motor 304 and two fixed side plates 301. Connecting plates 302 are fixedly connected to the top of both sides of the two fixed side plates 301. Adjustment grooves 306 are provided on opposite sides of each of the two connecting plates 302. The inner wall of 6 is movably connected with wedge blocks 305. An adjustment frame 303 is fixedly connected to the opposite side of each of the two wedge blocks 305. An adjustment screw 307 is fixedly connected to the two output ends of the two bidirectional synchronous motors 304. One end of each adjustment screw 307 is bolted through the two adjustment frames 303 to their interior. The height adjustment component 5 includes a support base 501. A multi-stage hydraulic rod 503 is provided on the top of each of the two support bases 501. A height adjustment base 504 is fixedly connected to the top of each of the two multi-stage hydraulic rods 503.

[0035] In use, the fixed side plate 301 is installed together with the support frame 105. A gap for height adjustment is left between the inner upper surface of the support frame 105 and the main load-bearing beam 201. By starting the bidirectional synchronous motor 304, its two output shafts drive the two adjusting screws 307 to rotate simultaneously. This drives the two adjusting frames 303 to move outward simultaneously. The wedge block 305 slides inside the adjusting groove 306. When the wedge block 305 is inserted into the adjusting groove 306, it presses the connecting plate 302 downward, and at the same time, it presses the fixed side plate 301 and the support frame 105 together. Simultaneously pressing downwards, the support frame 105 pulls the wire rope 104 downwards, thus making the taut wire rope 104 even tighter when it becomes loose, which helps to increase the overall tension. During the adjustment process, the connecting parts are fine-tuned, which has the advantage of high adjustment accuracy. When adjusting the height of the load-bearing components, two multi-stage hydraulic rods 503 are activated at the same time to extend them, thereby causing the height adjustment base 504 to lift the main load-bearing beam 201 upwards, thus completing the high-precision elevation adjustment operation. This solves the problem that the low elevation adjustment accuracy of the current pier connecting parts affects the quality of the pier structure.

[0036] It should also be noted that the pier assembly 1 includes a concrete pier 101. The interior of the concrete pier 101 is uniformly provided with multiple pier longitudinal reinforcement skeletons 103 along the circumferential direction. Multiple pier stirrup skeletons 102 are welded between the outer surfaces of the multiple pier longitudinal reinforcement skeletons 103. Four sets of steel wire ropes 104 are arranged between the multiple pier longitudinal reinforcement skeletons 103, and every two sets of steel wire ropes 104 arranged diagonally opposite each other are welded together. The bottom end of each set of steel wire ropes 104 is fixedly connected to a support frame 105.

[0037] Please see Figures 1 to 3 and Figure 7 The concrete pier 101 is the main body, providing a vertical load-bearing foundation to support all construction loads above. It is the stress origin of the entire support system. During the construction of the concrete pier 101, the longitudinal reinforcement skeleton 103 is fixed inside the concrete pier 101 with concrete, and multiple pier stirrup skeletons 102 are welded at equal intervals around the outer surface of the longitudinal reinforcement skeleton 103. By forming a steel mesh with the longitudinal reinforcement skeleton 103 and the stirrup skeleton 102, the tensile and shear strength of the concrete pier 101 can be enhanced, thereby preventing the main body from cracking. By crisscrossing four sets of steel wire ropes 104, an auxiliary bottom support function can be provided. After the steel wire ropes 104 are tightened, they apply an inward restraining force to the two main load-bearing beams 201 to offset the horizontal shear force, limit the lateral displacement of the main load-bearing beams 201, ensure the overall stability of the support system, and prevent the entire support from tilting or becoming unstable.

[0038] It should also be noted that the load-bearing component 2 includes two main load-bearing beams 201. Each main load-bearing beam 201 has a positioning groove 203 on its top. The bottom end of each set of steel wire ropes 104 passes through each positioning groove 203. The inner wall of the support frame 105 is movably connected to the outer surface of the main load-bearing beam 201. Each main load-bearing beam 201 has multiple reinforcing ribs 202 on its outer surface. The reinforcing ribs 202 are used to keep the main load-bearing beam 201 with the positioning groove 203 firmly in place. Multiple fastening I-beams 204 are fixedly connected between the tops of the two main load-bearing beams 201.

[0039] Please see Figures 1 to 3 By welding the top ends of the steel wire ropes 104 together and passing their bottom ends through the positioning grooves 203, a support frame 105 is installed at the bottom of the main load-bearing beam 201. This allows the steel wire ropes 104 to remain crossed, providing auxiliary tension to the concrete pier 101 and locking the main load-bearing beam 201 and the concrete pier 101 together, thus strengthening the connection. The main load-bearing beam 201 is the core load-bearing component, used to transmit the upper construction load, while the multiple fastening I-beams 204 are used to distribute the gravity generated by the upper construction load, providing the benefit of stable stress distribution.

[0040] It should also be noted that each fixed side plate 301 is fixedly installed on the same side of the two support brackets 105, the bidirectional synchronous motor 304 is fixedly installed on the top of the main load-bearing beam 201, and each adjustment frame 303 has a limit groove 309 on its inner bottom surface. Each limit groove 309 has a limit rod 308 slidably connected to its inner wall. The limit rod 308 is fixedly installed on the top of the main load-bearing beam 201.

[0041] Please see Figure 4 and Figure 5 By starting the bidirectional synchronous motor 304, the two adjusting screws 307 are driven to rotate simultaneously, which in turn drives the two adjusting frames 303 to move to both sides simultaneously. At this time, when the adjusting frame 303 moves, it slides inside the limiting groove 309 through the limiting rod 308, which can prevent the adjusting frame 303 from tilting up when moving, and keep the two wedge blocks 305 horizontal when moving.

[0042] It should also be noted that the concrete pier column 101 is externally equipped with a clamp assembly 4. The clamp assembly 4 includes a first arc-shaped clamp 401 and a second arc-shaped clamp 402, which are combined to form a ring clamp. The clamp assembly 4 also includes two locking mechanisms 41, each including a locking pin 411 and a locking buckle 410. The locking pin 411 is fixedly installed at the end of the first arc-shaped clamp 401, and the locking buckle 410 is fixedly installed at the end of the second arc-shaped clamp 402. The locking buckle 410 is inserted into the inside of the locking pin 411. Multiple locking racks 418 are symmetrically fixedly connected to the inner walls on both sides of the locking pin 411. A pull-out groove 412 is opened on one outer surface of the locking pin 411. Movable grooves 413 are opened on both inner walls of the pull-out groove 412. A movable plate 4111 is movably connected inside the pull-out groove 412. A pull rod 4110 is fixedly connected to one outer surface of the movable plate 4111, and the pull rod 4110 corresponds to and matches one outer surface of the locking pin 411. Two rotating grooves 4112 are symmetrically opened on the arc-shaped side of the movable plate 4111. Rotating rods 4113 are rotatably connected to the inner walls of the two rotating grooves 4112. Locking plates 4114 are fixedly connected to the outer surfaces of the two rotating rods 4113, and the two locking plates 4114 slide on the inner walls of the two movable grooves 413 respectively. A positioning slot 419 is opened at the top of the movable plate 4111, and an inner groove 415 is opened at the top of the locking pin 411. A sliding hole 414 is opened on the inner bottom surface of the inner groove 415. A positioning rod 416 is slidably connected between the inner walls of the positioning slot 419 and the sliding hole 414. A pull rod handle 417 is fixedly connected to the top of the positioning rod 416, and the pull rod handle 417 is inserted into the inner groove 415.

[0043] Please see Figure 2 , Figures 7 to 11By simultaneously inserting two locking pins 411 into the two locking buckles 410, the two locking plates 4114 pass through the two movable slots 413 and unfold. When the locking pins 411 are inserted into the locking buckles 410, the locking plates 4114 engage with the corresponding locking racks 418 in sequence. After the engagement is tightened, the installation of the first arc-shaped hoop 401 and the second arc-shaped hoop 402 is completed. This allows the hoop to be quickly and tightly installed on the outside of the concrete pier column 101, providing the advantage of convenient installation. During disassembly, simply pinch the pull rod handle 417 and push the positioning rod 416 out of the positioning slot 419 and the sliding hole 414. Pull out the positioning rod 416, which connects the locking pin 411 and the movable plate 4111. After pulling out, the movable plate 4111 separates from the locking pin 411. Next, pull out the pull rod 4110, thereby pulling out the movable plate 4111. At the same time, the locking plate 4114 will rotate around the center of the rotating rod 4113, and slide the locking plate 4114 from the movable groove 413 into the pull groove 412. At this time, the locking action between the locking buckle 410 and the locking pin 411 is eliminated, thereby quickly separating the first arc-shaped clamp 401 and the second arc-shaped clamp 402, which has the advantage of quickly removing the clamp.

[0044] It should also be noted that the two load-bearing seats 501 are fixedly installed on the outer surfaces of the first arc-shaped hoop 401 and the second arc-shaped hoop 402, respectively. The tops of the two height-adjustable bases 504 are in close contact with the bottoms of the two main load-bearing beams 201, and the bottoms of the two height-adjustable bases 504 are fixedly connected to two stabilizing rods 505. The tops of the two load-bearing seats 501 are provided with two limiting holes 506. The outer surface of each stabilizing rod 505 is slidably connected to the inner wall of the two limiting holes 506, and a reinforcing block 507 is fixedly connected between the bottoms of every two adjacent stabilizing rods 505. The tops of the two load-bearing seats 501 are fixedly connected to a reinforcing block 502.

[0045] Please see Figure 1 , Figure 2 and Figure 6 The height of the adjustable base 504 is adjusted by raising and lowering the multi-stage hydraulic rod 503. At this time, the stabilizing rod 505 slides inside the limiting hole 506, which ensures that the adjustable base 504 remains stable during the height adjustment and avoids left and right deviation. The bottom ends of the two stabilizing rods 505 are connected by the reinforcing block 507, which enhances the firmness of the two stabilizing rods 505. In addition, the reinforcing block 502 improves the firmness of the installation of the load-bearing seat 501.

[0046] The working principle of this device is as follows: During the construction of the concrete pier 101, the longitudinal reinforcement skeleton 103 is fixed inside the concrete pier 101 with concrete. Multiple pier stirrup skeletons 102 are welded at equal intervals around the outer surface of the longitudinal reinforcement skeleton 103. By forming a steel mesh with the longitudinal reinforcement skeleton 103 and the stirrup skeleton 102, the tensile and shear strength of the concrete pier 101 is enhanced. Four sets of steel wire ropes 104 are cross-laid. When the steel wire ropes 104 are tightened, an inward restraining force is applied to the two main load-bearing beams 201, restricting the lateral displacement of the main load-bearing beams 201. The top ends of the steel wire ropes 104 are welded together, and their bottom ends are passed through the positioning groove 203. A support frame 10 is installed at the bottom of the main load-bearing beam 201. 5. This allows the wire ropes 104 to remain crossed, locking the main load-bearing beam 201 and the concrete pier column 101 together. The main load-bearing beam 201 is the core load-bearing component, used to transfer the upper construction load, while multiple fastening I-beams 204 are used to distribute the gravity generated by the upper construction load. By installing the fixed side plate 301 and the support frame 105 together, a gap for height adjustment is left between the inner upper surface of the support frame 105 and the main load-bearing beam 201. By starting the bidirectional synchronous motor 304, its two output shafts drive the two adjusting screws 307 to rotate simultaneously, which in turn drives the two adjusting frames 303 to move outward simultaneously. The wedge block 305 slides inside the adjusting groove 306. When the wedge block 305 moves into the adjusting groove 306... During insertion, the connecting plate 302 is pressed downwards, simultaneously pressing the fixed side plate 301 and the support frame 105 downwards. The support frame 105 then pulls the wire rope 104 downwards. The connecting parts are fine-tuned during adjustment. When adjusting the height of the load-bearing component, two multi-stage hydraulic rods 503 are activated simultaneously to extend them, causing the height-adjusting base 504 to lift the main load-bearing beam 201. Two locking pins 411 are simultaneously inserted into two locking buckles 410. At this time, two locking plates 4114 pass through and unfold from the two movable slots 413. When the locking pins 411 are inserted into the locking buckles 410, the locking plates 4114 sequentially engage with the corresponding locking racks 418. After the engagement is tightened, the first arc-shaped hoop 401 is secured. For the installation of the second arc-shaped hoop 402, during disassembly, simply pinch the pull rod handle 417 and pull out the positioning rod 416 from the positioning slot 419 and the sliding hole 414. The positioning rod 416 connects the locking pin 411 and the movable plate 4111. After being pulled out, the movable plate 4111 separates from the locking pin 411. Next, pull out the pull rod 4110 to pull out the movable plate 4111. At the same time, the locking plate 4114 will rotate around the center of the rotating rod 4113 and slide from the movable slot 413 into the pull slot 412. At this time, the locking action between the locking buckle 410 and the locking pin 411 is eliminated, so that the first arc-shaped hoop 401 and the second arc-shaped hoop 402 can be quickly separated.
