Prefabricated building construction positioning and installation device and its construction method

Abstract

This invention discloses a prefabricated building construction positioning and installation device and its construction method, applicable to the field of precast component construction. The device includes an installation base frame equipped with a movable leveling component, a hanging mechanism, a positioning mechanism, an auxiliary docking mechanism, and several vertically distributed auxiliary fixing mechanisms. The auxiliary docking mechanism includes auxiliary support frame components symmetrically sliding on the installation base frame and a falling linkage component. In the construction method, the hanging mechanism is controlled to perform a falling action, engaging and pressing down the falling linkage component, which in turn causes the auxiliary support frame components on both sides to slide horizontally inward and close, converting longitudinal gravity into horizontal docking power. Finally, the auxiliary fixing mechanism performs multi-point vertical clamping and locking, and then retracts to a micro-gap rolling limit, coordinating with a multi-source winch to release and achieve flexible and stable placement of the component. This invention has advantages such as gravity self-drive, high synchronization, precise multi-dimensional adjustment, and flexible energy dissipation and collision prevention, significantly improving the construction efficiency and safety of prefabricated buildings.

Description

Technical Field

[0001] This invention relates to the field of prefabricated component construction technology, and in particular to a prefabricated building construction positioning and installation device and its construction method. Background Technology

[0002] With the acceleration of my country's construction industrialization process, prefabricated buildings, due to their characteristics of factory-prefabricated components and rapid on-site assembly, have become an important direction for the transformation and upgrading of the construction industry. The core of prefabricated buildings lies in the on-site installation of prefabricated components. How to achieve high-precision positioning, stable connection, and safe placement of prefabricated components directly affects the overall quality, safety, and construction efficiency of the building structure.

[0003] In traditional prefabricated building construction, tower cranes or truck cranes are mainly used for component hoisting. After hoisting, construction workers usually need to manually adjust the components at high altitudes using temporary supports, crowbars, manual jacks, or simple alignment tools. This method has the following prominent problems: First, positioning accuracy is difficult to guarantee. Affected by wind load, sling sway, and differences in human experience, components are prone to horizontal displacement, vertical deviation, and tilting, making it difficult to align with the bottom steel mesh and often requiring repeated adjustments, which seriously affects the construction progress. Second, the safety risks are high. Workers at heights need to perform dangerous operations on narrow platforms for extended periods, which can easily lead to falls or component falling accidents. Third, the construction efficiency is low. The installation time for a single component is long, and the manual labor intensity is high, which cannot meet the needs of rapid construction in large-scale prefabricated projects. Fourth, the impact force during component placement is difficult to control, which can easily damage the installed foundation or the component itself.

[0004] While some auxiliary installation tools have emerged in the existing technology, such as simple alignment frames, laser-assisted positioning instruments, or hydraulic support rods, most of these devices have only one function and can only solve local problems. They lack the integrated and coordinated capability of the entire process of hoisting, docking, fixing, and positioning, making it difficult to form effective mechanical linkage and multi-point coordinated adjustment. They cannot meet the requirements of high-precision, high-safety, and high-efficiency modern prefabricated building construction.

[0005] How to solve the above-mentioned technical problems is the problem faced by this invention. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a prefabricated building construction positioning and installation device and its construction method, which effectively solves the technical bottlenecks of difficult positioning, alignment, fixing, and high impact during prefabricated building construction, and provides a reliable mechanized solution for the high-quality and high-efficiency development of prefabricated buildings.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a prefabricated building construction positioning and installation device, including an installation base frame, a movable leveling component is provided on the installation base frame, a lifting mechanism for hoisting building components is provided on one side of the installation base frame, a positioning mechanism that cooperates with the bottom steel bars is provided on the installation base frame, an auxiliary docking mechanism that cooperates with the lifting mechanism is provided on the installation base frame, and a plurality of auxiliary fixing mechanisms are vertically provided on the installation base frame; The auxiliary docking mechanism includes auxiliary support frame assemblies symmetrically arranged on the positioning base frame and slidingly engaged with the positioning base frame.

An auxiliary frame is provided on one side of the auxiliary slide, the docking and placement assembly is provided at the top of the auxiliary frame, and a translational leveling unit is provided at the bottom of the auxiliary frame. The structure of the translation leveling unit is the same as that of the moving leveling component.

[0009] Furthermore, the falling linkage component includes a falling guide frame disposed at the top of the mounting frame, a falling guide groove is provided on the falling guide frame, a falling slide is provided in the falling guide groove, and a plurality of translational balls are provided on the top surface of the falling slide to cooperate with the positioning mechanism. The lowering slide is provided with a linkage slide that slides with the mounting frame. Both sides of the linkage slide are provided with linkage arms that are rotatably connected to the auxiliary slide. The mounting frame is provided with a mounting groove that cooperates with the auxiliary slide. The mounting frame is provided with a reset unit that cooperates with the linkage slide. The top surface of the mounting frame is provided with a shock-absorbing unit that cooperates with the lowering slide.

[0010] Furthermore, the docking and placement assembly includes a placement groove formed on the top surface of the auxiliary frame, a docking base that slides and engages with the placement groove, and a placement moving unit for controlling the docking base to be arranged along the length direction of the placement groove on the auxiliary frame. The docking base is provided with a mounting guide at its center, and a mounting slide is provided on the mounting guide for sliding cooperation with the mounting guide. The top surface of the mounting slide is provided with a shock-absorbing roller unit that cooperates with the positioning mechanism. Support plate units are provided on both sides of the docking base. Both sides of the docking base are provided with clamping guides, and the clamping guides are provided with clamping slide plate units that slide with the clamping guides. The mounting slide is symmetrically provided with two placement guide rods that are connected to the clamping slide plate units, and the docking base is provided with a reset member that cooperates with the mounting slide.

[0011] Furthermore, the auxiliary fixing mechanism includes a fixed slide that slides with the mounting frame, the mounting frame is provided with a vertical control unit for controlling the vertical movement of the fixed slide, the fixed slide is provided with a leveling and positioning component that cooperates with the auxiliary docking mechanism, and the fixed slide is provided with a clamping and fixing component for clamping and fixing building components.

[0012] Specifically, the clamping and fixing assembly includes two sets of clamping claw frames symmetrically arranged on the fixed slide. Each set of clamping claw frames includes several clamping claw frames vertically arranged on the fixed slide. The fixed slide is provided with a drive frame, and the drive frame is provided with a drive slide that slides with the drive frame. The drive frame is also provided with a linear drive component that cooperates with the drive slide. Two sets of clamping drive arms that cooperate with the clamping claw frames are symmetrically arranged on the drive slide. Each set of clamping claw frames is connected to the same clamping connecting plate.

[0013] Furthermore, the suspension mechanism includes a main suspension frame, on which a lifting ring is provided, and two sets of sling winch assemblies are symmetrically arranged on both sides of the main suspension frame. The main suspension frame is provided with a positioning base plate that cooperates with the falling linkage assembly, and the main suspension frame is provided with a counterweight base plate that cooperates with the positioning base plate. The bottom surface of the building component is provided with a flexible support cloth that cooperates with the hoisting winch assembly; The positioning mechanism includes a positioning base disposed on the movable base, a plurality of positioning slots being provided on the positioning base, a positioning rod being disposed in the positioning slot, and a positioning arc member being provided at one end of the positioning rod; and an auxiliary sling assembly being provided on the auxiliary frame.

[0014] The construction positioning method for prefabricated buildings includes the following steps: S1. Drive the installation base frame to the designated construction area through the moving leveling component, and lock the position with the existing steel bars through the positioning mechanism; S2. Use the hoisting mechanism to hoist the building components to a preset height above the mounting base; S3. Control the hanger mechanism to perform a falling action. The falling hanger mechanism contacts and presses down the falling linkage component, thereby linking the two auxiliary support frame components to slide synchronously along the mounting base. The docking and placement component on the auxiliary support frame component performs receiving and coordinated falling guidance for the hanger mechanism. S4. The docking and installation component is used to drive the building component to perform horizontal displacement fine-tuning, and the auxiliary fixing mechanism is used to drive the building component to perform spatial posture and relative spacing adjustment. S5. After the building component is adjusted to the preset installation posture, several vertically distributed auxiliary fixing mechanisms are activated to clamp and lock the outer wall of the building component from multiple height positions.

[0015] S6: By using the auxiliary sling assembly on the auxiliary support frame assembly to link with the sling winch assembly in the sling mechanism, the building components are pulled and fixed, and the building components are controlled to slowly fall into place.

[0016] Furthermore, in step S3, the coordinated descent guidance step includes: S31. During the descent process, the positioning base plate at the bottom of the hanging mechanism contacts and applies pressure to the translational ball on the top surface of the descent slide in the descent linkage assembly. S32. The pressured falling slide slides down along the falling guide groove, causing the linkage slide to move down synchronously. S33. The lowered linkage carriage drives the two auxiliary carriages to slide towards each other along the mounting groove on the mounting frame through the linkage arms on both sides, thereby causing the two auxiliary frames and their docking assembly to close towards the center position below the hanger mechanism.

[0017] Furthermore, step S6 specifically includes: S61. After step S5 is completed, the auxiliary sling assembly is activated, and the auxiliary sling is connected to the flexible support cloth pre-laid on the bottom surface of the building component. S62. Synchronously control the sling winch assembly and the auxiliary sling assembly in the sling mechanism to release the sling and auxiliary sling in a linkage manner. S63. While the auxiliary fixing mechanism is holding the structure in place, the weight of the building component is gradually and smoothly transferred through the flexible support cloth to the suspension system formed by the auxiliary sling assembly and the sling winch assembly, and finally slowly sinks to the installation foundation surface.

[0018] This invention achieves synchronous lowering of the hanging frame mechanism and the auxiliary support frame assembly through a lowering linkage component. Combined with the multi-stage sliding and multi-degree-of-freedom adjustment structure of the docking and placement component, it can make precise adjustments to the horizontal, vertical and posture of building components, effectively reducing the deviation caused by traditional manual alignment and ensuring accurate alignment of components with the bottom steel bars.

[0019] This invention employs an auxiliary fixing mechanism to clamp and lock the component at multiple height positions, combined with a shock absorption unit and a safety buffer structure, to effectively prevent the component from shaking or falling during installation; the linkage design between the auxiliary sling assembly and the main sling enables the gradual and smooth transfer of load, avoiding the impact risk caused by sudden unloading.

[0020] This invention cleverly converts the gravitational potential energy of the falling component into mechanical energy that drives the auxiliary support frames on both sides to synchronously and precisely close. This purely mechanical linkage mechanism requires no additional power and can automatically complete the capture and alignment during the component's descent. It also achieves a soft landing through a shock absorption unit, effectively solving the problems of component swaying in the air and large impact during docking, thus improving the docking success rate and safety.

[0021] The translational ball bearings on the top surface of the falling slide in this invention transform the traditional rigid surface-to-surface collision into rolling friction, effectively eliminating the horizontal shear impact force at the moment of contact. Combined with the elastic energy storage buffer system composed of shock-absorbing spring components and return springs, it can efficiently absorb the inertial impact load of the falling components, completely avoiding cracks or deformation damage to the foundation steel bars caused by rigid hard collisions during the docking of precast components.

[0052] Furthermore, the suspension mechanism 3 includes a main suspension frame 30, on which a lifting ring 31 is provided, and two sets of sling winch assemblies 32 are symmetrically arranged on both sides of the main suspension frame 30. The main suspension frame 30 is provided with a positioning base plate 33 that cooperates with the falling linkage assembly 51, and the main suspension frame 30 is provided with a counterweight base plate 34 that cooperates with the positioning base plate 33. The bottom surface of the building component is provided with a flexible support cloth that cooperates with the sling winch assembly 32; The positioning mechanism 4 includes a positioning base 40 disposed on the movable base 10, a plurality of positioning slots 41 are provided on the positioning base 40, a positioning rod 42 is provided in the positioning slot 41, and a positioning arc member 43 is provided at one end of the positioning rod 42; and an auxiliary sling assembly 7 is provided on the auxiliary frame 502.

[0053] Specifically, the auxiliary sling assembly 7 includes a sling auxiliary slide 70 that slides with the auxiliary frame 502, an auxiliary control unit 71 that cooperates with the sling auxiliary slide 70 on the auxiliary frame 502, a sling winch 72 on the sling auxiliary slide 70, an auxiliary motor 73 on the sling winch 72, and an auxiliary sling 74 that cooperates with the flexible support cloth on the sling winch 72.

[0054] The construction positioning method for prefabricated buildings includes the following steps: S1. The installation base 1 is moved to the designated construction area by the moving leveling component 2, and its position is locked with the existing steel bars by the positioning mechanism 4. After the device moves to the preset trajectory, the positioning mechanism 4 is activated. The positioning rod 42 is inserted into the gap of the existing steel bars in the ground, and the positioning arc part 43 at the end of the positioning rod 42 locks the existing steel bars, thereby establishing a solid positioning base point for the entire device. Subsequently, the moving leveling component 2 is used to perform macroscopic leveling of the moving base 10, providing a reference coordinate system for the precise docking of subsequent building components.

[0055] S2. The building components are hoisted to a predetermined height above the mounting base 1 using the hoisting mechanism 3; S3. Control the hanging mechanism 3 to perform a falling action. The falling hanging mechanism 3 contacts and presses down the falling linkage component 51, thereby linking the two auxiliary support frame components 50 to slide synchronously along the mounting base 1, and the hanging mechanism 3 is supported and guided to fall in coordination by the docking and placement component 54 on the auxiliary support frame component 50. The building components are hoisted to the top of the mounting base 1 using a tower crane or main gantry 30 mechanism 3 and controlled to fall vertically. When the main gantry 30 falls to the trigger height, the positioning plate 33 at the bottom of the main gantry 30 contacts the translation ball 513 on the top surface of the falling slide 512 in the falling linkage assembly 51 and performs rigid downward pressure. After being subjected to longitudinal gravity load, the falling slide 512 slides vertically down the falling guide groove 511, and drives the linkage slide 514 to slide down synchronously along the mounting frame 11.

[0056] During this process, the sliding linkage carriage 514 generates a lateral force through the linkage support arms 515 rotatably connected on both sides, forcibly driving the two symmetrically arranged auxiliary carriages 501 to slide horizontally towards each other along the mounting grooves 516 on the mounting frame 12, thereby causing the two auxiliary frames 502 to close towards the axis of the building component. The docking assembly 54, located at the top of the auxiliary frame 502, then closes to directly below the main hanger 30, performing a lifting and connecting operation on the main hanger 30, completing the self-driven coarse positioning process that converts 100% of the vertical falling gravitational potential energy of the component into a horizontal docking driving force.

[0057] S4. The docking and installation component 54 is used to drive the building component to perform horizontal displacement fine adjustment, and the auxiliary fixing mechanism 6 is used to drive the building component to perform spatial posture and relative spacing adjustment. After the docking and placement assembly 54 completes its lifting, the building component is in a temporary supported state. At this time, the placement movement unit 542 in the docking and placement assembly 54 is activated, driving the docking base 541 to move along the length direction of the placement slide 540 to correct the linear deviation of the building component on the horizontal first axis. If the building component sways on the horizontal second axis, the building component presses against the shock-absorbing roller unit 546, causing the placement slide 544 to overcome the resistance of the return spring and move along the placement guide 543, using the elastic rebound force of the return spring to achieve automatic flexible centering and repositioning of the component.

[0058] Simultaneously, the vertical control unit 61 in the auxiliary fixing mechanism 6 is activated, driving the fixed carriages 60 at each height segment to rise and fall along the mounting frame 11 to the corresponding matching height. Through the leveling and positioning components 62 on the fixed carriages 60, the horizontal overhang length of each fixed carriage 60 relative to the mounting frame 11 is finely adjusted, thereby axially compensating and refining the spatial verticality and horizontal tilt angle of the building components.

[0059] S5. After the building component is adjusted to the preset installation posture, several vertically distributed auxiliary fixing mechanisms 6 are activated to clamp and lock the outer wall of the building component from multiple height positions.

[0060] Once the spatial installation posture of the building component is finely adjusted to the preset standard, the clamping and fixing components 63 on each set of fixed slides 60 are activated to converge inward, implementing a horizontal enclosing rigid clamping and locking of the outer wall of the building component from multiple height positions. At this time, the spatial degree of freedom of the building component is completely restricted, enabling it to stably resist external wind loads or rope swings, maintain a static state in space, and complete the temporary fixing during construction.

[0061] S6: By using the auxiliary sling assembly 7 on the auxiliary support frame assembly 50 to link with the sling winch assembly 32 in the hanger mechanism 3, the building components are pulled and fixed, and the building components are controlled to slowly fall into place.

[0062] When the building component is clamped and constrained, the clamping hydraulic rod in the auxiliary fixing mechanism 6 is activated to perform a slight retraction, so that the clamping plate is no longer in rigid contact with the outer wall of the building component, and a sliding gap of 2mm~5mm is maintained. At the same time, the guide wheel hydraulic rod is kept in the extended state, and the rolling outer edge of the guide wheel is used to abut against the outer wall of the component.

[0063] Subsequently, the auxiliary sling 74 of the auxiliary sling assembly 7 is attached to the flexible support fabric laid on the bottom surface of the building component. The two sets of sling winch assemblies 32 of the main sling 30 and the sling winch 72 of the auxiliary sling assembly 7 are controlled to perform multi-source linkage rope release, using the flexible support fabric to lift the building component. Since the clamping plate has receded to a micro-gap limit, while the building component is laterally limited by the rolling guide wheels on its outer wall, its longitudinal vertical freedom is released. The building component begins to slowly and smoothly sink to the final installation foundation surface along the rolling limit trajectory of the guide wheels.

[0064] Furthermore, in step S3, the coordinated descent guidance step includes: S31. During the descent process, the positioning base plate 33 at the bottom of the hanging mechanism 3 contacts and applies pressure to the translation ball 513 on the top surface of the descent slide 512 in the descent linkage assembly 51. S32. The pressured falling slide 512 slides down along the falling guide groove 511, causing the linkage slide 514 to move down synchronously. S33. The lowered linkage slide 514 drives the two auxiliary slides 501 to slide towards each other along the mounting groove 516 on the mounting frame 12 through the linkage support arms 515 on both sides, so that the two auxiliary frames 502 and their docking assembly 54 close together at the center position below the hanger mechanism 3.

[0065] Furthermore, step S6 specifically includes: S61. After step S5 is completed, the auxiliary sling assembly 7 is activated, and the auxiliary sling 74 is connected to the flexible support cloth pre-laid on the bottom surface of the building component. S62. Synchronously control the sling winch assembly 32 in the sling mechanism 3 and the sling winch 72 in the auxiliary sling assembly 7 to release the sling and the auxiliary sling 74 in a linkage manner. S63. While the auxiliary fixing mechanism 6 is holding the structure in place, the weight of the building component is gradually and smoothly transferred through the flexible support cloth to the suspension system formed by the auxiliary sling assembly 7 and the sling winch assembly 32, and finally slowly sinks to the installation foundation surface.
