Description

Technical Field

[0001] This invention belongs to the field of prefabricated building technology, specifically relating to a construction method for a fully prefabricated multi-story concrete factory building. Background Technology

[0002] With the development of the social economy, in order to improve the level of economical and intensive use of industrial land, improve resource allocation efficiency, and promote industrial agglomeration, governments at all levels have successively issued policy documents to promote the construction of industrial buildings and high-standard factory buildings, and a large number of multi-story and high-rise concrete factory buildings have begun to be built.

[0003] Multi-story concrete plant buildings have relatively regular horizontal and transverse structures, featuring modularity, standardization, and universality, making them favorable for the promotion and implementation of prefabricated construction. In response to the national and local government calls for the vigorous promotion of prefabricated buildings, it is necessary to explore prefabricated multi-story concrete plant building structural systems that conform to the characteristics of industrialized construction, actively practicing the new development concept of "innovation, coordination, green development, openness, and sharing." Governments at all levels also have requirements for the prefabrication rate of industrial multi-story plant building projects. However, industrial multi-story concrete plant buildings generally have large spans, high floor heights, large component sizes, and heavy weights. Using traditional prefabricated construction methods results in high transportation and on-site hoisting costs, and requires sophisticated hoisting machinery, inevitably leading to a significant increase in construction costs. This makes it difficult to promote the application of traditional prefabricated construction methods in industrial multi-story concrete plant building projects. Many industrial multi-story concrete plant building projects either still use labor-intensive, extensive cast-in-place construction methods, or hesitate to proceed due to local policy requirements for prefabrication rates and construction costs.

[0004] This invention focuses on the research of efficient and economical construction technology for fully prefabricated multi-story concrete plant buildings with industrial upper floors. It forms key intelligent construction technologies for industrial upper-story concrete plant buildings with modern industrialization characteristics, achieving cost reduction and efficiency improvement. This not only solves the industry problem of the difficulty in applying prefabricated construction of industrial upper-story concrete plant buildings, but also greatly improves the level of technological progress in my country's construction industry. It will also strongly promote the high-quality development of industrial upper-story concrete plant building construction in my country, promote industrial agglomeration, and further enhance its supporting and leading role in national economic development and opening up to the outside world. Summary of the Invention

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of this invention is to provide a construction method for a fully prefabricated multi-story concrete factory building, which aims to solve the problems existing in the prior art.

[0006] To achieve its objectives, the present invention employs the following technical solution:

[0007] A construction method for a fully prefabricated multi-story concrete workshop includes the following steps:

[0008] 1) First, based on the project schedule and the characteristics of the factory layout and long longitudinal length, a temporary prefabrication site is reasonably arranged on the construction site for the on-site prefabrication of large components such as beams and columns, while components such as floor slabs and wall panels that can be divided into conventional transportation / hoisting units are prefabricated in the factory.

[0009] Even better, large column and beam components are prefabricated using intelligent and mechanized assembly molds in a streamlined manner.

[0010] 2) Arrange conventional tower cranes at reasonable locations on the factory building's structural plan to be responsible for the vertical transportation of large prefabricated components such as columns and beams from the ground to each floor, as well as the installation of composite floor slabs and wall panels.

[0011] The layout of conventional tower cranes is designed to minimize the horizontal transport volume from the unloading point of large precast beam and column components to each installation location, while also covering the hoisting requirements of composite floor slabs and precast wall panels.

[0012] Depending on the characteristics of the factory project and cost control requirements, conventional tower cranes may not be required. Instead, truck cranes or crawler cranes may be used to handle the vertical transportation of large precast column and beam components, as well as the hoisting of composite floor slabs and precast wall panels.

[0013] 3) Signal devices are set up at the installation points of floor beams and columns, and large prefabricated column and beam components are transported from the vertical transport unloading point to the corresponding installation point along the floor according to the installation process plan using an automatic navigation transport device.

[0014] More preferably, the automatic navigation transport device has an automatic unloading function and should be equipped with a multi-level low-flatbed trolley group according to the load-bearing requirements of the lower floor slab.

[0015] 4) Intelligent hoisting robots capable of self-lifting and horizontal self-movement are used to sequentially install large precast column and beam components for each floor. Tower cranes positioned around the factory perimeter are used to hoist and install precast composite floor slabs and precast wall panels, as well as pour concrete for the floors. The specific steps are as follows:

[0016] S1. Pre-set the installation route on the floor plan, the installation route including longitudinal route and transverse route;

[0017] S2. Lay a track device on the installation route, and install an intelligent hoisting robot on the track device;

[0018] S3. The intelligent hoisting robot hoisted and installed the prefabricated column and beam components required for the factory building on the track device and along the longitudinal route;

[0019] S4. The intelligent hoisting robot includes a self-elevating device. At the turning point of the installation route, the driving end of the self-elevating device causes the intelligent hoisting robot to disengage from the track device of the longitudinal route and connect with the track device of the transverse route formed after the track turns. The intelligent hoisting robot performs hoisting and installation of the prefabricated column and beam components required for the factory building on the track device and along the transverse route.

[0020] S5. At the turning point of the transverse installation route, the drive end of the self-elevating device causes the intelligent hoisting robot to disengage from the track device of the transverse route and connect with the track device of the longitudinal route formed after the track turns. The intelligent hoisting robot then hoists and installs the prefabricated column and beam components required for the factory building on the track device and along the longitudinal route.

[0021] S6. After completing the floor plan of this floor, the intelligent hoisting robot is raised to the installed floor plan by the self-lifting device, and the steps S1 to S5 above are repeated until the installation of the multi-story factory roof is completed.

[0022] Specifically, in step S2, the track device includes a movable conversion steel beam, embedded parts, and track components. The movable conversion steel beam is laid on the floor plane through the embedded parts, and the track components are located on the upper surface of the movable conversion steel beam.

[0023] Specifically, the number of track devices is no less than two sets, and each set of track devices includes two movable conversion steel beams symmetrically arranged on both sides of the installation route.

[0024] Specifically, the intelligent hoisting robot also includes an inner tower body, an outer tower body, a walking device, and a hoisting device;

[0025] The outer tower body serves as the load-bearing structure during the hoisting operation of the intelligent hoisting robot, while the inner tower body serves as the guiding and load-bearing structure during the self-elevating upstairs operation of the intelligent hoisting robot. The inner tower body and the outer tower body work together to form the self-elevating upstairs system of the intelligent hoisting robot.

[0026] The self-elevating device is located between the inner tower body and the outer tower body, and includes a lifting cylinder and a lifting beam. The inner tower body is provided with a lower mounting base, and the outer tower body is provided with an upper mounting base. The lifting cylinder is connected to the lower mounting base through the lifting beam, and the lifting cylinder is connected to the upper mounting base.

[0027] The outer tower body is provided with a traveling base frame, and the traveling device is located on the traveling base frame. The traveling device includes a traveling mounting seat, a steering shaft, a traveling motor, a traveling connecting seat, traveling wheels, and a rail clamp. The traveling mounting seat is connected to the traveling base frame. The two ends of the steering shaft are respectively rotatably engaged with the traveling mounting seat and the traveling connecting seat. The traveling motor, traveling wheels, and rail clamp are located on the traveling connecting seat. The drive end of the traveling motor is used to drive the traveling wheels to rotate.

[0028] The hoisting device is connected to the outer tower body.

[0029] Specifically, in steps S3, S4, and S5, the specific steps for the intelligent hoisting robot to move along the track device are as follows:

[0030] The track device is divided into a first group of track devices and a second group of track devices. When the intelligent hoisting robot moves to the second group of track devices and installs the precast column and beam components within the range of the first group of track devices, the intelligent hoisting robot is used to dismantle and hoist the first group of track devices and then take over the second group of track devices for installation along the installation route. Similarly, when the precast column and beam components within the range of the second group of track devices are installed, the intelligent hoisting robot is used to dismantle and hoist the second group of track devices and then take over the first group of track devices for installation along the installation route. This process is repeated until the intelligent hoisting robot moves to the column space at the other end of the factory building.

[0031] Specifically, in steps S4 and S5, the specific steps for the intelligent hoisting robot to turn and move at the turning point of the installation route are as follows:

[0032] A support beam is installed below the intelligent hoisting robot as a support for its ascent. The support beam is located on the floor level. After the self-elevating device raises the robot's walking device to a certain height, the track device below it is removed and the robot is rotated 90° before installation. Then, the walking direction of the intelligent robot's walking device is adjusted to match the direction of the track device below it before it falls back onto the track-shifting device and continues walking. When encountering another turning point in the installation route, the lifting and lowering steps of the intelligent robot are repeated, ensuring that the track device below it is aligned with the walking direction of the intelligent robot.

[0033] Specifically, in steps S3, S4, and S5, the hoisting and installation of the precast column and beam components includes installing the required support columns, frame beams, and secondary beams. Then, conventional tower cranes are used to hoist and install the precast composite floor slabs and precast wall panels, as well as pour the floor concrete. In the last support column of the intelligent hoisting robot's travel path, the secondary beams and precast composite floor slabs are not installed temporarily, leaving an upward passage for the intelligent hoisting robot to ascend to the upper floor.

[0034] Specifically, in step S6, the intelligent hoisting robot raises itself to the next floor level using the self-elevating device. The specific steps are as follows:

[0035] The intelligent hoisting robot is used to remove the preceding track device and lift it to the vicinity of the predetermined installation position on the next floor, without obstructing the passage area for the intelligent hoisting robot to ascend to the next floor.

[0036] A support beam is installed below the inner tower of the intelligent hoisting robot to support its self-lifting ascent. The self-lifting device of the intelligent hoisting robot raises its walking device to an appropriate position at the top elevation of the predetermined track installation location. After the track device, which has been hoisted to the predetermined placement location, is installed in place, the self-lifting device completes the descent of the intelligent hoisting robot and the connection between it and the track device. Finally, the inner tower of the intelligent hoisting robot retracts, resets, and is fixed.

[0037] Specifically, before step S1, conventional tower cranes are arranged in the factory building structure plan to be responsible for the vertical transportation of precast column and beam components from the ground to each floor, as well as the installation of composite floor slabs and wall panels. The arrangement of the conventional tower cranes is based on minimizing the horizontal transportation volume from the unloading point of the precast column and beam components to each installation position, and covering the hoisting requirements of composite floor slabs and precast wall panels.

[0038] If a truck crane or crawler crane can cover the hoisting requirements of precast components in the factory, it can also be used to complete the vertical transportation of precast column and beam components, as well as the hoisting of composite floor slabs and precast wall panels, depending on cost control requirements.

[0039] Finally, in step S7, the intelligent hoisting robot and track device are dismantled using a conventional tower crane or truck crane, or by employing mechanical equipment such as a lifting pole.

[0040] Compared with the prior art, the beneficial effects of the present invention are:

[0041] The construction method for fully prefabricated multi-story concrete workshops proposed in this invention can achieve full coverage of hoisting operations for large prefabricated beams and columns on each floor using a single intelligent hoisting robot. This changes the previous disadvantage of using multiple large hoisting devices and incurring high costs when constructing multi-story concrete workshops using traditional prefabricated construction methods. It also realizes the mechanization and intelligentization of the entire construction process of fully prefabricated multi-story concrete workshops, breaking through the industry dilemma of "high cost of traditional prefabricated construction methods for industrial multi-story concrete workshops and the continued use of cast-in-place construction methods in many projects". This method reduces costs and improves efficiency, not only filling the international and domestic gaps in key technologies for the industrialization of industrial multi-story concrete workshop construction, leading and promoting the development of prefabricated buildings and intelligent construction in my country, but also having significant implications for improving the level of technological progress in my country's building industrialization.

Detailed Implementation

[0054] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below. 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.

[0055] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0056] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0057] See attached diagram. Figures 1 to 9 :

[0058] This plan takes a three-story, two-span, five-bay, fully precast concrete multi-story factory building as an example. Figure 1The diagram shows the standard floor plan of a multi-story precast concrete factory building. The support columns 1 have a spacing of 15m × 15m, a cross-sectional dimension of 1200mm × 1200mm, and a height of 8000mm. The frame beams 2 have two dimensions with cross-sectional dimensions of 400mm × 1500mm and 300mm × 1200mm respectively. The secondary beams 3 have a cross-sectional dimension of 250mm × 900mm and a spacing of 2.5m. The composite floor slab 4 has a thickness of 150mm.

[0059] According to this scheme, a construction method for a fully prefabricated multi-story concrete workshop is provided, including the following steps:

[0060] 1) Targeting Figure 1 The structure of the factory building requires prefabricated frame beams 2 weighing 18.63 tons and 10.87 tons respectively, with a length of 13.8 meters; prefabricated secondary beams 3 weighing 6.84 tons and with a length of 14.6 meters; prefabricated support columns 1 weighing 28.8 tons; and prefabricated composite floor slabs 4 with dimensions of 2250mm × 3650mm and a weight of 1.23 tons.

[0061] Due to the large size and heavy weight of precast beams and columns, traditional methods of transporting them from the factory to the construction site are costly and have high transportation requirements. Considering the typical site layout and long longitudinal length of multi-story concrete workshop projects, temporary precasting areas can be set up at the construction site, such as temporary roads, for on-site precasting of large beams and columns. Even better, leveraging the long longitudinal length of the project site, intelligent and mechanized assembly molds can be used for a streamlined precasting process for beams and columns. For precast composite floor slabs and precast wall panels, their size and weight can be categorized into conventional transportation / hoisting units, precast in the factory, and transported to the construction site. Specifically:

[0062] 2) Conventional tower cranes are arranged in the factory building structure plan to be responsible for the vertical transportation of precast column and beam components from the ground to each floor, as well as the installation of composite floor slabs 4 and wall panels. The arrangement of the conventional tower cranes is based on minimizing the horizontal transportation volume from the unloading point of the precast column and beam components to each installation position, and covering the hoisting requirements of composite floor slabs 4 and precast wall panels.

[0063] If a truck crane or crawler crane cannot cover the hoisting requirements of prefabricated components in the factory, a truck crane or crawler crane can be used to complete the vertical transportation of prefabricated column and beam components, as well as the hoisting of composite floor slabs and prefabricated wall panels, depending on cost control requirements.

[0064] 3) For the above transportation, signal devices are set at the floor column and beam installation points, and large column and beam prefabricated components are transported from the vertical transportation unloading point to the corresponding installation point along the floor according to the installation process plan through an automatic navigation transportation device. More preferably, the automatic navigation transportation device has an automatic unloading function and should take into account the load-bearing requirements of the lower floor slab, and adopt a multi-level low flatbed trolley group.

[0065] 4) Intelligent hoisting robots capable of self-lifting and horizontal self-movement are used to sequentially install large precast column and beam components for each floor. Tower cranes positioned around the factory perimeter are used to hoist and install precast composite floor slabs and precast wall panels, as well as pour concrete for the floors. The specific steps are as follows:

[0066] S1. Pre-set the installation route on the floor plan, such as Figure 2 The installation route is U-shaped, including a longitudinal route and a transverse route;

[0067] S2. Lay a track device 5 on the installation route, and install an intelligent hoisting robot 6 on the track device 5;

[0068] Specifically, the track device 5 includes a movable transfer steel beam 501, embedded parts, and track components 502. The movable transfer steel beam 501 is laid on the floor plane through the embedded parts, and the track components 502 are located on the upper surface of the movable transfer steel beam 501. The track device 5 consists of two sets, namely a first set and a second set. Each set of track devices 5 includes two movable transfer steel beams 501 symmetrically arranged on both sides of the installation route. The intelligent hoisting robot 6 is installed on the first set of track devices 5 using a tower crane or a truck crane.

[0069] like Figures 8 to 9 The intelligent hoisting robot 6 includes an inner tower body 601, an outer tower body 602, a walking device 603, a hoisting device 604, and a self-elevating device 605;

[0070] The inner tower body 601 and the outer tower body 602 are in sliding engagement;

[0071] The self-elevating device 605 is located between the inner tower body 601 and the outer tower body 602, and includes a lifting cylinder 60501 and a lifting beam 60502. The inner tower body 601 is provided with a lower mounting base 60503, and the outer tower body 602 is provided with an upper mounting base 60504. The lifting cylinder 60501 is connected to the lower mounting base 60503 through the lifting beam 60502, and the lifting cylinder 60501 is connected to the upper mounting base 60504.

[0072] The outer tower body 602 is provided with a traveling base frame 606, and the traveling device 603 is provided on the traveling base frame 606. The traveling device 603 includes a traveling mounting seat 60301, a steering shaft 60302, a traveling motor 60303, a traveling connecting seat 60304, a traveling wheel 60305, and a rail clamp 60306. The traveling mounting seat 60301 is connected to the traveling base frame 606. The two ends of the steering shaft 60302 are respectively rotatably engaged with the traveling mounting seat 60301 and the traveling connecting seat 60304. The traveling motor 60303, the traveling wheel 60305, and the rail clamp 60306 are provided on the traveling connecting seat 60304. The driving end of the traveling motor 60303 is used to drive the traveling wheel 60305 to rotate.

[0073] The outer tower body 602 is equipped with a tower crane body, and the hoisting device 604 is connected to the outer tower body 602 through the tower crane body.

[0074] S3. The intelligent hoisting robot 6 hoists and installs the prefabricated column and beam components required for the factory building on the track device 5 and along the longitudinal route.

[0075] S4. The intelligent hoisting robot 6 includes a self-lifting device 605. At the turning point of the installation route, the drive end of the self-lifting device causes the intelligent hoisting robot 6 to disengage from the track device 5 of the longitudinal route and connect to the track device 5 of the transverse route. The intelligent hoisting robot 6 performs hoisting and installation of the prefabricated column and beam components required for the factory building on the track device 5 and along the transverse route.

[0076] S5. At the turning point of the horizontal installation route, the drive end of the self-elevating device causes the intelligent hoisting robot 6 to disengage from the track device 5 of the horizontal route and connect to the track device 5 of the longitudinal route. The intelligent hoisting robot 6 then hoists and installs the prefabricated column and beam components required for the factory building on the track device 5 and along the longitudinal route.

[0077] Specifically, such as Figure 3 In steps S3, S4, and S5, the specific steps for the intelligent hoisting robot 6 to move along the track device 5 are as follows:

[0078] The track device 5 consists of a first set of track devices 5 and a second set of track devices 5. When the intelligent hoisting robot 6 moves to the second set of track devices and completes the installation of the precast column and beam components within the range of the first set of track devices 5, the intelligent hoisting robot 6 is used to dismantle and hoist the first set of track devices 5, and then carries the second set of track devices for installation. Similarly, after the precast column and beam components within the range of the second set of track devices 5 are installed, the intelligent hoisting robot 6 is used to dismantle and hoist the second set of track devices 5, and then carries the first set of track devices for installation. This process is repeated until the intelligent hoisting robot 6 moves to the column space at the other end of the factory building.

[0079] Specifically, such as Figure 4 and Figure 5 In steps S4 and S5, the specific steps for the intelligent hoisting robot 6 to turn and move at the turning point of the installation route are as follows:

[0080] A support beam 607 is installed below the intelligent hoisting robot 6 as a support for its ascent. The support beam 607 is located on the floor level. After the self-lifting device 605 raises the walking device 603 to a certain height, the track device 5 below it is removed and rotated 90° for installation. Then, the walking direction of the intelligent robot's walking device 603 is adjusted to be consistent with the direction of the track device 5 below it before it falls back onto the track device 5 and continues to move. When it encounters another turning point in the installation route, the lifting and lowering steps of the intelligent robot are repeated, and the track device 5 below it is aligned with the direction of travel of the intelligent robot.

[0081] Specifically, in steps S3, S4, and S5, the hoisting and installation of the precast column and beam components includes installing the required support columns 1, frame beams 2, and secondary beams 3. Then, conventional tower cranes are used to hoist and install the precast composite floor slabs 4 and precast wall panels, as well as pour the floor concrete. In the last support column 1 of the intelligent hoisting robot 6's travel route, the secondary beams 3 and precast composite floor slabs 4 are not installed temporarily, leaving an upward passage for the intelligent hoisting robot 6 to ascend to the upper floor.

[0082] S6. After completing the floor plan of this layer, the intelligent hoisting robot 6 is raised to the installed floor plan via the self-elevating device 605, and the steps S1 to S5 above are repeated until the installation of the multi-story factory roof is completed. The specific steps for the intelligent hoisting robot 6 to be raised to the top of the installed floor plan via the self-elevating device 605 are as follows:

[0083] like Figure 6 and Figure 7The intelligent hoisting robot 6 is used to remove the preceding track device 5 and hoist it to the vicinity of the predetermined installation position on the next floor, without obstructing the passage area for the intelligent hoisting robot 6 to ascend to the next floor.

[0084] A support beam 607 is installed below the inner tower body 601 of the intelligent hoisting robot 6 as a support for self-lifting to the upper floor. The self-lifting device 605 of the intelligent hoisting robot 6 is used to raise its walking device 603 to an appropriate position at the top elevation of the predetermined track device 5. After the track device 5, which has been hoisted to the predetermined placement location, is installed in place, the self-lifting device 605 completes the descent of the intelligent hoisting robot 6 and the connection between it and the track device 5. Finally, the inner tower body 601 of the intelligent hoisting robot 6 is retracted, reset, and fixed.

[0085] S7. The intelligent hoisting robot 6 and the track device 5 are dismantled using conventional tower cranes or truck cranes, or by using mechanical equipment such as jacks.

[0086] The construction method for fully prefabricated multi-story concrete workshops proposed in this invention utilizes a single intelligent hoisting robot. Through changes in the position and angle of the track device and the walking device, along with a self-lifting mechanism, it achieves full coverage of hoisting operations for large prefabricated beams and columns across floors. This eliminates the need for transition tracks at turning points in the installation route, saving space and installation costs. It overcomes the disadvantages of traditional prefabricated construction methods for multi-story concrete workshops, which required multiple large hoisting devices and incurred high costs. Furthermore, it achieves mechanization and intelligentization of the entire construction process for fully prefabricated multi-story concrete workshops, breaking through the industry dilemma of "high costs associated with traditional prefabricated construction methods for industrial multi-story concrete workshops, and the continued reliance on cast-in-place construction in many projects." This method reduces costs and improves efficiency, filling the international and domestic gaps in key technologies for the industrialization of industrial multi-story concrete workshop construction, leading and promoting the development of prefabricated buildings and intelligent construction in my country, and significantly contributing to the advancement of my country's building industrialization technology.
