Description

A movable precast concrete wall panel structure and installation method Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a movable precast concrete wall panel structure and its installation method. Background Technology

[0002] Industrialized construction, an emerging production method, is an effective means of urbanization in my country. Prefabricated concrete shear wall structures, as an important form of industrialized construction, are highly suitable for the construction of affordable housing and subsidized housing. The construction speed and assembly quality of prefabricated shear wall structures directly affect the progress of industrialized construction and the pace of urbanization in my country. Although my country has made some progress in the construction technology and installation processes of prefabricated shear walls in recent years, some problems still exist in the hoisting and installation of prefabricated shear wall components.

[0003] The main problems lie in low assembly efficiency and significant safety hazards. During the construction of precast concrete shear wall structures, precast concrete wall panels, processed at the precast concrete component factory, are first transported to the precast construction site, then hoisted and assembled. When the precast concrete wall panels are transported to the designated installation location by tower crane, they need to be spliced ​​together using wall sleeves or bolts. During this process, installation workers need to manually align the sleeve holes or bolt holes. Since the wall components are usually quite heavy, manual operation consumes a lot of manpower, and safety hazards are easily generated during the long periods when the tower crane is suspended. Summary of the Invention

[0004] To demonstrate that precast concrete wall panels can be quickly hoisted, with high stability, high assembly efficiency, and good safety, this application provides a movable precast concrete wall panel structure and installation method.

[0005] In a first aspect, this application provides a movable precast concrete wall panel structure, which adopts the following technical solution:

[0006] A movable precast concrete wall panel structure includes a transport platform, a support body, and an installation platform. The transport platform is placed horizontally, and multiple rollers are fixed to its bottom, distributed at the corners of the platform. A servo motor for driving the rollers in both directions is fixed to the bottom of the platform. The support body is rotatably connected to the transport platform, with its rotation axis perpendicular to the vertical direction of the transport platform. The installation platform is horizontally fixed to the end of the support body away from the transport platform and is symmetrically arranged along the support body. Reels are fixed to both sides of the installation platform perpendicular to the transport platform's direction of travel, and the reels are wound with... There is a winding cord, and locking components are provided at both ends of the winding cord. The locking components include a lock frame, a first spring, and a screw. The lock frame is fixedly connected to the winding cord. Two sides connected by the same side edge of the lock frame are missing. The inside of the lock frame is connected to the outside. A partition perpendicular to the missing surface is fixed in the middle of the lock frame. The partition abuts against the side edge of the lock frame. One end of the first spring is fixed to the inner wall of the lock frame, and the other end is fixed to the tail end of the screw. The first spring is in a compressed state. The screw passes through the partition and the side wall away from the first spring. The end of the screw away from the first spring is set with a beveled surface. A lifting ring is fixed on the precast concrete wall panel. The beveled surface of the screw faces the lifting ring.

[0007] By adopting the above technical solution, the barge platform is placed horizontally, and the servo motor can drive the rollers to move in both directions, so that the barge platform can move back and forth. The support body is rotatably connected to the barge platform, and the support body can drive the installation platform to rotate. The two sides of the installation platform are symmetrically arranged along the support body to facilitate maintaining the balance of the installation platform. Two precast concrete wall panels can be hoisted on both sides of the installation platform at the same time. The locking component on the roller can face the lifting ring on the precast concrete wall panel. The chamfered surfaces of the lifting ring and the screw slide relative to each other, the first spring is compressed, and after the lifting ring passes through the screw, the first spring returns to its initial length, and the screw passes through the locking frame, thus achieving the purpose of rapid hoisting of precast concrete wall panels. Moreover, it eliminates the need for workers to use bolts or other means to fix the transport, making it convenient, fast, safe and efficient.

[0008] Optionally, the reel is provided with bidirectional guide grooves, which are symmetrically arranged along the middle position of the reel.

[0009] By adopting the above technical solution, the winding on the spool is wound bidirectionally along the guide groove. The winding starts from the middle of the spool and winds towards both ends. Locking components are provided at both ends of the winding. The locking components can quickly hoist the precast concrete wall panel without the need for workers to fix it with hooks. This makes it more stable and safer.

[0010] Optionally, telescopic plates are fixed on both sides of the installation platform that are perpendicular to the direction of travel of the barge platform, and the roller is fixed on the side of the telescopic plates that are far apart from each other.

[0011] By adopting the above technical solution, the telescopic plate can change the length of the installation platform, and the distance can be adjusted according to the specific location during the installation of precast concrete wall panels, making the installation of precast concrete wall panels faster and more efficient.

[0012] Optionally, the barge platform is provided with two sets of limiting plates. The two sets of limiting plates are symmetrically arranged along the support body. Each set of limiting plates has two plates. The two limiting plates are arranged perpendicular to the traveling direction of the barge platform and are arranged parallel to each other in the traveling direction. The limiting plates are slidably connected to the barge platform, and the sliding direction is along the direction of approaching or moving away from the installation platform.

[0013] By adopting the above technical solution, when the locking component lifts the precast concrete wall panel, the precast concrete wall panel is placed between the two limiting plates. The precast concrete wall panel leans against the middle of the limiting plates, which can prevent the precast concrete wall panel from swaying and shaking, and increase the stability of the precast concrete wall panel hoisting.

[0014] Optionally, a buffer layer is fixed on the outer wall of the limiting plate and on the side of the transport platform near the installation platform.

[0015] By adopting the above technical solution, a buffer layer is added to the outer wall of the transport platform and the limiting plate. When the precast concrete wall panel is placed on the transport platform, it can prevent the precast concrete wall panel from being bumped and worn, thus preventing unnecessary losses.

[0016] Optionally, a pad is fixed to the bottom of the installation platform, and the pad is slidably connected to the installation platform. The sliding direction is along the direction of approaching or moving away from the support body, and the end of the limiting plate away from the transport platform is provided with an arc.

[0017] By adopting the above technical solution, when the precast concrete wall panel is leaned against the limiting plates, the end closer to the installation platform leans against the pad. The pad and the limiting plates simultaneously provide support for the precast concrete wall panel, which can increase the stability of the precast concrete wall panel during transportation.

[0018] Optionally, a first motor is fixed inside the barge platform, a gear is fixed on the motor shaft of the first motor, and a rack is fixed on one side wall of the limiting plate that extends into the barge platform, and the rack meshes with the gear for transmission.

[0019] By adopting the above technical solution, the first motor can drive the gear to rotate, the gear meshes with the rack, the rotation of the gear drives the rack to move in the vertical direction, thereby moving the limiting plate in the vertical direction, and the meshing force between the gear and the rack can increase the support force and stability of the limiting plate.

[0020] Optionally, a counterweight is slidably connected to the top of the installation platform, with the sliding direction parallel to the travel direction of the barge platform. Second springs are fixed on both sides of the counterweight, and the end of the second spring away from the counterweight is fixed to the telescopic plate.

[0021] By adopting the above technical solution, precast concrete wall panels can be hoisted on both sides of the installation platform, and the counterweight can slide relative to the installation platform, thereby ensuring that the installation platform can maintain balance during hoisting.

[0022] Optionally, the counterweight is fixed with a slider and a pulley at the bottom, and multiple grooves are opened parallel to each other on the top surface of the mounting platform. The slider and pulley are respectively located inside the grooves and slide and are limited. The sliding direction is along the traveling direction of the barge platform or in the opposite direction. A second motor for driving the counterweight to slide is fixed on the mounting platform.

[0023] By adopting the above technical solution, precast concrete wall panels are hoisted on both sides of the installation platform. When the weight of the precast concrete wall panels on both sides is inconsistent, causing the installation platform to be unbalanced, the second motor will drive the counterweight to slide. At this time, the slider and pulley slide and are limited inside the groove. The pulley can reduce the friction of the slider, making the counterweight slide more smoothly.

[0024] Secondly, this application provides a method for installing a movable precast concrete wall panel, employing the following technical solution:

[0025] A method for installing a movable precast concrete wall panel includes the following steps:

[0026] S1. Use the locking assembly to hook the precast concrete wall panel;

[0027] S2. Start the first motor and raise the limit plate to limit the precast concrete wall panel;

[0028] S3. Servo motors drive the transport platform to deliver precast concrete wall panels to the installation location.

[0029] S4. Lower the height of the limit plate, extend the telescopic plate, and control the hoisting of the precast concrete wall panel.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. The locking component enables the rapid hoisting of precast concrete wall panels without the need for workers to disassemble and fix them, resulting in more stable and efficient hoisting.

[0032] 2. The precast concrete wall panel, which has been hoisted by hook, is leaned against the limiting plate and pad and transported to the installation site for hoisting. This can effectively reduce the damage to the precast concrete wall panel during hoisting and achieve a more stable and efficient transportation effect.

[0033] 3. The counterweights on the installation platform help maintain its stability. Attached Figure Description

[0040] The present application will be further described in detail below with reference to Figures 1-5.

[0041] This application discloses a movable precast concrete wall panel structure.

[0042] Referring to Figure 1, a movable precast concrete wall panel structure includes a transport platform 2 and an installation platform 3, both of which are rectangular. The transport platform 2 is placed horizontally, and a stabilizer 21 is fixed on the transport platform 2. A support 22 is rotatably connected to the stabilizer 21, and a rotating shaft 23 is fixed at the bottom of the support 22. The rotating shaft 23 is inserted into the stabilizer 21, and the rotation axis of the support 22 is perpendicular to the vertical direction of the transport platform 2. The installation platform 3 is fixed at the end of the support 22 away from the transport platform 2 and is arranged parallel to the transport platform 2. The support 22 can rotate relative to the stabilizer 21, that is, the installation platform 3 can rotate relative to the transport platform 2. Four rollers 24 are fixed at the bottom of the transport platform 2 and are distributed at the four corners of the transport platform 2. A servo motor 241 is fixed at the bottom of the transport platform 2, and the servo motor 241 can drive the rollers 24 to move in both directions, thereby realizing the reciprocating motion of the transport platform 2.

[0043] Referring to Figures 1 and 2, telescopic plates 4 are fixed on both sides of the installation platform 3, perpendicular to the travel direction of the transport platform 2. The installation platform 3 is symmetrically arranged along the support body 22. For ease of explanation, the following description will use one side of the installation platform 3 as an example. The length of the telescopic plate 4 is equal to the width of the installation platform 3. The telescopic plate 4 is rectangular, and its outer wall is fixed to the edge of the installation platform. The movable end of the telescopic plate 4 can extend the movable length of the installation platform 3. A rotating rod 41 is fixed to the movable end of the telescopic plate 4. A reel 42 is fixed on the rotating rod 41. A rotating motor 44 is fixed to one end of the rotating shaft 23. The rotating motor 44 drives the rotating rod 41 to rotate, and the rotating rod 41 drives the reel 42 to rotate. A bidirectional guide groove 421 is provided on the reel 42. The guide groove 421 is symmetrically arranged along the middle position of the reel 42. A winding thread 43 is wound on the reel 42. Both ends of the winding thread 43 can rise and fall simultaneously along the guide groove 421. Turntables 422 are fixed to both ends of the reel 42 to prevent the winding thread 43 from falling off the reel 42.

[0044] Referring to Figures 1 and 3, locking components 5 are provided at both ends of the winding 43. Each locking component 5 includes a locking frame 51, a first spring 52, and a screw 53. The locking frame 51 is fixed to the winding 43. Two sides of the locking frame 51 connected by the same side edge are missing, and the interior of the locking frame 51 is open to the outside. A partition perpendicular to the missing surface is fixed in the middle of the locking frame 51, and the partition abuts against the side edge of the locking frame 51. One end of the first spring 52 is fixed to the inner wall of the locking frame 51, and the other end is fixed to the tail end of the screw 53. The first spring 52 is in a compressed state. A nut 531 is threadedly connected to the tail end of the screw 53 to restrain the screw. The extension range of screw 53 is such that screw 53 penetrates the partition and the side wall away from the first spring 52. The end of screw 53 away from the first spring 52 is provided with a beveled surface. A lifting ring 11 is fixed on the side of the precast concrete wall panel 1. The beveled surface of screw 53 faces the lifting ring 11. When the beveled surface of screw 53 is brought close to the lifting ring 11, the lifting ring 11 slides relative to the beveled surface of screw 53, and the spring is compressed at the same time. When screw 53 penetrates into the interior of lifting ring 11, the spring returns to its initial length. In this way, the hoisting does not require workers to use hooks to lift and then fix with bolts, which reduces the labor of workers and increases the stability of hoisting.

[0045] Referring to Figures 1 and 4, a counterweight 6 is slidably connected to the installation platform 3, sliding in the direction of movement of the transport platform 2. Three straight grooves 32 are provided on the installation platform 3, running in the same direction as the transport platform 2. A T-shaped slider 62 is fixed to the bottom of the counterweight 6, and pulleys 63 are fixed to both sides of the T-shaped slider 62. The slider 62 and the pulleys 63 slide and are limited within the grooves 32. A second motor 64 is fixed to the installation platform 3, driving the counterweight 6 to slide. Second springs 61 are fixed to both sides of the counterweight 6 near the telescopic plate 4. One end of each second spring 61 is fixed to the outer wall of the counterweight 6, and the other end is fixed to the outer wall of the telescopic plate 4. When the counterweight 6 slides to one side, the force of compression from the second spring 61 on the same side and the force of tension from the second spring 61 on the other side prevent the counterweight 6 from sliding too far, causing the installation platform 3 to become completely unbalanced, thus maintaining the stability of the installation platform 3.

[0046] Referring to Figures 1 and 5, two sets of limiting plates 7 are provided on the side of the transport platform 2 perpendicular to its running direction. The transport platform 2 is symmetrically arranged along the stabilizer 21, and the two sets of limiting plates 7 are symmetrically arranged along the stabilizer 21. Each set of limiting plates 7 has two plates, and the two limiting plates 7 are parallel to each other in the direction away from the stabilizer 21. The limiting plates 7 are slidably connected to the transport platform 2, and the sliding direction is along the direction of approaching or moving away from the mounting platform 3. A first motor 8 is fixed inside the transport platform 2, and a gear 81 is fixed on the motor shaft of the first motor 8. A rack 71 is fixed on the limiting plate 7. The gear 81 and the rack 71 mesh and drive each other. When the first motor 8 is started, the first motor 8 can drive the gear 81 to rotate. The gear 81 meshes and drives the rack 71, and the rack 71 drives the limiting plate 7 to rise and fall relative to the transport platform 2. A fixing plate 311 is fixed on the bottom side of the mounting platform 3 perpendicular to the running direction of the transport platform 2. The fixing plate 311 has a back... A groove is provided on one side away from the support body 22, and a pad 31 is slidably connected inside the groove. The sliding direction of the pad 31 is along the direction close to or away from the support body 22. The end of the pad 31 away from the fixed plate 311 is a beveled surface with an obtuse angle to the horizontal direction. The end of the limiting plate 7 away from the transport platform 2 is arc-shaped, and a buffer layer 72 is fixed on the outer wall of the limiting plate 7 and the transport platform 2. The locking component 5 hooks up the precast concrete wall panel 1, and the precast concrete wall panel 1 leans against the limiting plates 7. The end of the precast concrete wall panel 1 close to the installation platform 3 leans against the pad 31. The buffer layer 72 on the limiting plate 7 and the buffer layer 72 on the transport platform 2 can effectively reduce the wear of the precast concrete wall panel 1. The arc shape of the limiting plate 7 and the beveled surface of the pad 31 can effectively increase the stability of the precast concrete wall panel 1 and reduce the swaying and shaking of the precast concrete wall panel 1 during transportation.

[0047] The implementation principle of a movable precast concrete wall panel structure in this application embodiment is as follows: the locking component 5 hooks up the lifting ring 11 on the precast concrete wall panel 1, the position of the telescopic plate 4 is adjusted, and the precast concrete wall panel 1 is placed between the limiting plates 7. The side of the precast concrete wall panel 1 closest to the installation platform 3 leans against the pad 31. The precast concrete wall panel 1 is lifted by hooks on both sides of the installation platform 3. The counterweight 6 slides relative to the installation platform 3 to maintain the balance of the installation platform 3. The servo motor 241 drives the roller 24 to move. The transport platform 2 drives the installation platform 3 to transport the precast concrete wall panel 1 to the installation location for hoisting.

[0048] This application also discloses an installation method for a movable precast concrete wall panel 1.

[0050] S1. Use locking component 5 to hook the lifting ring 11 of the precast concrete wall panel 1;
