Description

Technical Field

[0001] This invention relates to building engineering technology, specifically to a rapid support device for prefabricated building formwork. Background Technology

[0002] In prefabricated building construction, cranes are often used to hoist precast wall and floor slab formwork (or modules) for on-site assembly. A typical assembly method involves pre-installed reinforcing bars in the lower formwork, while the upper formwork to be assembled has corresponding insertion holes. During construction, the upper formwork is hoisted to the designated position, ensuring the insertion holes are accurately aligned and fitted with the pre-installed reinforcing bars in the lower formwork, thus achieving structural connection and fixation.

[0003] Because precast formwork is large and heavy, it is difficult to achieve precise adjustments using only lifting equipment. The formwork is prone to swaying in the air due to factors such as wind and swaying of the slings. To achieve alignment, workers usually need to observe closely and manually push or guide the heavy formwork suspended in the air. This is not only labor-intensive and inefficient, but also makes it difficult to accurately control the amount of movement of the formwork under manual pushing. It is very likely to collide with the fixed structure or steel bars, seriously threatening the personal safety of the observing and operating workers and posing a major risk of injury. Summary of the Invention

[0004] The purpose of this invention is to provide a rapid support device for prefabricated building formwork, in order to solve the problems in the prior art where prefabricated formwork is large in size, heavy in weight, and prone to swaying during hoisting. To complete the hole alignment, workers often need to manually push it at close range, which is not only inefficient, but also prone to collisions due to the difficulty in controlling the amount of formwork movement, seriously threatening the personal safety of the operators.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rapid support device for prefabricated building formwork, comprising a bracket A, wherein one side of the bracket A has an opening and the other side is provided with a guide rail A, and further comprising:

[0006] The movable frame has an A movable groove at one end, which is fitted onto the outside of the A guide rail and slidably connected thereto. A B guide rail is provided on one side of the A movable frame along its length.

[0007] A clamping part has a B movable groove on one side, which is sleeved on the outside of B guide rail and slidably connected to it;

[0008] B clamping part is hinged to one side of A clamping part;

[0009] The locking element is provided on clamping part A and clamping part B to fix or release clamping part A and clamping part B, thereby achieving pre-fixation of the pre-reserved steel bars in the building formwork;

[0010] Support B is fixedly installed on support A, and support B is used to limit the movement of the hoisted building formwork;

[0011] A crossbeam, which is slidably mounted on bracket B, is capable of moving up and down;

[0012] A partition, which is installed on the crossbeam, is used to limit the movement of the hoisted building formwork;

[0013] An adjusting rod is provided on one side of the partition, and the adjusting rod is used to adjust the distance between the partition and the crossbar.

[0014] Furthermore, a clamping member is threadedly connected to the crossbeam, which can clamp the outer wall of the B bracket, thereby fixing or releasing the crossbeam from the B bracket.

[0015] Furthermore, the locking element includes:

[0016] A fixing block is fixedly installed on the outer wall of A clamping part;

[0017] Fixed block B is fixedly installed on the outer wall of clamping part B, and fixed blocks A and B are arranged symmetrically.

[0018] A screw, one end of which is rotatably mounted on a fixed block A or a fixed block B, the screw having a hollow structure, and a limit groove provided at the other end, with a fastening nut threaded onto the outer side of the screw;

[0019] The pressure plate is sleeved on the outside of the screw, and the pressure plate part is located inside the limiting groove;

[0020] An elastic element A is disposed inside the screw, and one end of the elastic element A abuts against the pressure plate.

[0021] Furthermore, a piston is fixedly installed at the bottom corner of the A bracket, and a cylinder liner is sleeved on the outside of the piston. The outside of the piston slides and seals with the inner wall of the cylinder liner. An elastic element B is provided at the bottom end of the piston and the bottom of the inner wall of the cylinder liner, and the elastic element B abuts against the piston.

[0022] Furthermore, a caster wheel is rotatably mounted on the bottom end of the cylinder liner.

[0023] Furthermore, the crossbar has a transverse adjustment groove extending along its length. Two sliders are slidably installed inside the transverse adjustment groove. The sliders are penetrated by an adjustment rod, which is threaded to the outside of the slider and its end is ball-jointed to the partition plate.

[0024] Furthermore, a handle is fixedly installed on one side of the A bracket.

[0025] Compared with existing technologies, the present invention provides a prefabricated building formwork rapid support device. This device achieves stable pre-fixation by fixing the A clamping part and the B clamping part to the reinforcing bars of the installed formwork via locking components. The lateral position is adjusted by sliding the movable frame along the A guide rail of the A support, and the longitudinal position is adjusted by sliding the A clamping part along the B guide rail of the movable frame, accommodating reinforcing bars with different spacings. Lateral compression and limiting of the hoisted formwork is achieved by the B support and the cross frame in conjunction with partitions and adjusting rods, suppressing swaying. Continuous guidance is achieved during descent by the cross frame sliding synchronously with the formwork on the B support, ensuring precise alignment between the pre-drilled holes of the hoisted formwork and the reinforcing bars, thus improving installation safety and assembly efficiency.

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] As attached Figure 1 To be continued Figure 6 As shown:

[0037] Example 1:

[0038] This invention provides a rapid support device for prefabricated building formwork, including a support A 1, with an opening on one side and a guide rail A 11 on the other side, and further comprising:

[0039] The movable frame 2 has an A movable groove 22 at one end, which is fitted onto the outside of the A guide rail 11 and slidably connected thereto. A B guide rail 21 is provided on one side of the movable frame 2 along the length direction.

[0040] A clamping part 31 has a B movable groove 311 on one side. The B movable groove 311 is sleeved on the outside of the B guide rail 21 and is slidably connected to it.

[0041] B clamping part 32 is hinged to one side of A clamping part 31;

[0042] A locking element is provided on clamping part A 31 and clamping part B 32 to fix or release clamping part A 31 and clamping part B 32, thereby achieving pre-fixation of the reserved steel bars in the building formwork.

[0043] B bracket 61 is fixedly installed on A bracket 1. B bracket 61 is used to limit the hoisting of the building formwork.

[0044] The crossbeam 62 is slidably mounted on the bracket B 61, and the crossbeam 62 can move up and down.

[0045] Partition 71, which is installed on the cross frame 62, is used to limit the hoisting of the building formwork;

[0046] An adjusting rod 72 is located on one side of the partition 71 and is used to adjust the distance between the partition 71 and the crossbar 62.

[0047] The A-support 1, made of metal, forms the basic support structure. Its A-guide rail 11 is slidably connected to the A-moving groove 22 of the movable frame 2, allowing the movable frame 2 to move horizontally to adjust its lateral position. The B-guide rail 21 on the movable frame 2 is slidably connected to the B-moving groove 311 of the A-clamping part 31, allowing the A-clamping part 31 to move longitudinally to adjust its front-to-back position, suitable for reinforcing bars with different spacing. After the hinged A-clamping part 31 and B-clamping part 32 are fixed by locking devices, the pre-reserved reinforcing bars on the fixed building formwork can be firmly clamped, achieving pre-fixation and positioning of the entire device. After the hoisted building formwork is initially placed between the B-supports 61 by the lifting equipment, its sides are subjected to B-supports 61. The initial positioning of the support 61 can be adjusted by manually or with a tool-driven adjusting rod 72 to adjust the distance between the partition 71 and the crossbeam 62, so that the partition 71 fits tightly against and squeezes one side of the building formwork, effectively clamping and limiting the building formwork and significantly reducing its swaying caused by external forces in the air; during the process of the building formwork slowly descending, aligning and inserting the reinforcing bars, the crossbeam 62 can slide down synchronously with the building formwork on the B support 61, so that the partition 71 can continuously provide stable lateral limiting and guiding functions, ensuring that the reserved holes of the building formwork can be smoothly and accurately aligned and inserted into the reinforcing bars, greatly reducing the risk of collision caused by formwork swaying and improving the safety and accuracy of hoisting and splicing;

[0048] Under current technology, due to the large size and heavy weight of precast formwork, it is difficult to achieve precise adjustments using only lifting equipment. The formwork is prone to swaying in the air due to wind and the swinging of the slings. To achieve alignment, workers usually need to observe closely and manually push or guide the heavy, suspended formwork. This is not only labor-intensive and inefficient, but also makes it difficult to precisely control the movement of the formwork under manual force, which could potentially lead to collisions with the fixed structure or reinforcing steel, seriously threatening the personal safety of the observing and operating workers and posing a significant risk of injury.

[0049] This solution addresses the aforementioned problems as follows: The device is used on pre-fixed formwork. After the horizontal formwork is laid, when the pre-reserved reinforcing bars on the horizontal formwork need to be inserted into the spliced ​​formwork, clamping parts A 31 and B 32 are first fitted onto the outside of the reinforcing bars and secured with locking devices. When a crane lifts the formwork to be spliced ​​and inserts the pre-reserved splicing holes into the reinforcing bars, the formwork, suspended in mid-air, is first manually and stably placed between supports B 61 by workers. Adjusting rods 72 are used to adjust partitions 71 to compress and limit the formwork, reducing swaying and increasing stability. This also limits the pre-reserved holes to better align with the reinforcing bars. The lifted formwork slowly descends and inserts into the reinforcing bars, with the horizontal frame 62 following suit, maintaining a stable descent of the lifted formwork, reducing swaying, and enhancing the safety and stability of the formwork installation.

[0050] A clamping element 63 is threaded onto the crossbeam 62. The clamping element 63 can press against the outer wall of the B bracket 61, so that the crossbeam 62 and the B bracket 61 are fixed or unfixed.

[0051] After the crossbeam 62 is adjusted to a suitable height on the B-bracket 61 to match the position of the hoisted building formwork, the clamping member 63 connected to the crossbeam 62 is screwed on, causing its end to move inward and press tightly against the outer wall of the B-bracket 61. The static friction generated securely locks the crossbeam 62 at the current height position, preventing the crossbeam 62 from accidentally sliding up and down when the building formwork is hoisted, lowered, or subjected to lateral forces. When it is necessary to readjust the height or assemble again, the clamping member 63 is loosened in the opposite direction to release the pressure on the B-bracket 61, thereby restoring the sliding function of the crossbeam 62. This achieves a quick and reliable switch between fixing and de-fixing the crossbeam 62 and the B-bracket 61.

[0052] Locking components include:

[0053] A fixing block 33 is fixedly installed on the outer wall of A clamping part 31;

[0054] B fixing block 34 is fixedly installed on the outer wall of B clamping part 32, and A fixing block 33 and B fixing block 34 are arranged symmetrically.

[0055] The screw 35 has one end rotatably mounted on the A fixing block 33 or the B fixing block 34. The screw 35 has a hollow structure, and the other end has a limit groove 38. A fastening nut is threaded on the outside of the screw 35.

[0056] The pressure plate 36 is sleeved on the outside of the screw 35, and part of the pressure plate 36 is located inside the limiting groove 38;

[0057] An elastic element 37 is disposed inside the screw 35, and one end of the elastic element 37 abuts against the pressure plate 36.

[0058] The locking mechanism works by using the clamping force generated by the engagement of the screw 35 and the fastening nut. When clamping parts A 31 and B 32 close to enclose the pre-reserved reinforcing bar, the symmetrically arranged fixing blocks A 33 and B 34 approach each other. Rotating the fastening nut causes the screw 35 to move towards fixing block B 34 due to the threaded engagement, thus pressing the pressure plate 36 against the outer wall of fixing block B 34. The elastic element A 37 is a damping spring, and the elastic element A 37 inside the screw 35 continuously exerts pressure on the pressure plate 36. 6. Applying an outward force ensures that the pressure plate 36 maintains elastic contact with the inner side of the fastening nut within the limiting groove 38, and achieves separation in the non-tightened state. This provides a certain pre-tightening force and buffer during the locking process. Furthermore, before pre-tightening the A clamping part 31 and the B clamping part 32, the pressure plate 36 on the screw 35 can be directly rotated to the side of the B fixing block 34 away from the A fixing block 33. This also compensates for minor gaps caused by uneven clamping surfaces or dimensional changes, making the clamping more uniform and reliable, and ensuring a firm and stable pre-fixation of the reinforcing bar.

[0059] A piston 41 is fixedly installed at the bottom corner of bracket A. A cylinder liner 42 is sleeved on the outside of the piston 41. The outside of the piston 41 slides and seals with the inner wall of the cylinder liner 42. An elastic element B 43 is provided at the bottom of the piston 41 and the bottom of the inner wall of the cylinder liner 42. The elastic element B 43 abuts against the piston 41.

[0060] The piston 41, installed at the bottom corner of bracket A 1, and the cylinder liner 42 form a retractable buffer structure. When the hoisted building formwork experiences a slight collision during docking or the device is impacted by uneven ground, the impact force is transmitted to the piston 41 through bracket A 1. The piston 41 then slides within the cylinder liner 42 and compresses the elastic element B 43 located below it. The elastic element B 43 is a spring or elastic column, etc. The elastic element B 43 converts part of the impact kinetic energy into elastic potential energy and absorbs it, thereby effectively buffering and attenuating the impact vibration. This buffering effect not only protects the structure of the device itself, but also reduces the vibration transmitted to the fixed formwork and reinforcing bars, providing a more stable reference platform for the precision alignment operation being carried out above.

[0061] A caster wheel 5 is rotatably mounted on the bottom end of cylinder liner 42.

[0062] The omnidirectional wheels 5, which are rotated and installed at the bottom of the cylinder liner 42, enable the entire support device to move flexibly. Workers can easily push or pull the device to move it freely on the construction ground to different template splicing positions. After the device has pre-fixed the reinforcing bars through the clamping part, the omnidirectional wheels 5 can still provide a certain amount of fine adjustment margin, which is convenient for making minor position corrections during final positioning, greatly improving the mobility and work efficiency of the device.

[0063] A transverse adjustment groove is provided through the cross frame 62 along its length. Two sliders 73 are slidably installed inside the transverse adjustment groove. The sliders 73 are penetrated by the adjustment rod 72. The outer side of the adjustment rod 72 is threadedly connected to the sliders 73, and its end is ball-jointed to the partition plate 71.

[0064] The transverse adjustment groove on the crossbeam 62 provides a horizontal sliding track for the two sliders 73. When the adjustment rod 72 is rotated, it drives the partition 71 to move laterally, thereby adjusting the clamping width between the partition 71 and the B-bracket 61 to accommodate building templates of different thicknesses. The adjustment rod 72, which is ball-jointed with the partition 71, plays a role in deflection adjustment, allowing the partition 71 to produce a small angular deflection when subjected to pressure from the side of the template. This allows the partition 71 to better fit the side of the template, which may not be completely vertical, achieving a more stable and flexible limiting effect. The cooperation between the two adjustment rods 72 and the sliders realizes a composite adjustment function of single-degree-of-freedom translation and certain angle self-adaptation of the partition 71.

[0065] A handle 8 is fixedly installed on one side of bracket A1.

[0066] The handle 8, which is fixedly installed on one side of bracket A1, provides a point of leverage for the operator.

[0067] Working principle: First, push handle 8 to move the device via casters 5 to the side of the fixed building formwork. Slide the movable frame 2 along guide rail A 11 to adjust its lateral position, and slide clamping part A 31 along guide rail B 21 to adjust its longitudinal position, so that clamping part A 31 and clamping part B 32 are fitted onto the outside of the reserved reinforcing bars. Rotate the screw 35 and fastening nut of the locking component, and the pressure plate 36 presses the fixing block B 34 under the action of elastic element A 37, fixing clamping part A 31 and clamping part B 32. Then, hoist the building formwork to be spliced ​​and place it into support B. Between the frames 61, slide the crossbeam 62 to a suitable height, tighten the clamping part 63 to fix the crossbeam 62 on the B support 61, rotate the adjusting rod 72 to drive the slider 73 to slide in the transverse adjusting groove, so that the partition plate 71 presses the side of the building formwork for limiting; then, the hoisted building formwork is slowly lowered, and the crossbeam 62 slides down synchronously with the building formwork on the B support 61, the partition plate 71 continuously provides lateral limiting, and the piston 41 compresses the B elastic part 43 in the cylinder liner 42 to buffer the impact; finally, the reserved holes of the building formwork are aligned and the reinforcing bars are inserted to complete the splicing.

[0068] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
