Description

[0002] With the surging demand for ultra-large precision equipment and instruments in the industrial manufacturing sector, large-span and ultra-high space factories, as a new generation of industrial infrastructure, have exceeded the physical limits of traditional industrial buildings in terms of construction scale.

[0003] This type of factory building generally has a span exceeding 100 meters and a cornice height exceeding 80 meters to meet special process requirements such as aerial assembly of super-large components and three-dimensional maintenance of heavy equipment. Existing construction equipment generally uses large-scale lifting equipment for hoisting. However, for such construction requirements, the lifting height of existing equipment is limited, and large-scale lifting equipment is relatively rare. In addition, for large-span construction requirements, too much lifting equipment is required, which is too expensive. At the same time, the use of lifting construction makes it difficult to connect the upper and lower sections of the building structure, resulting in poor overall structural stability and construction safety. Therefore, people began to study lifting devices to lift the main steel structure. However, in actual construction practice, the existing lifting construction technology exposed significant technical bottlenecks, especially in the construction stability of ultra-high sections and the reliability of structural fixation. There are systematic defects, which seriously restrict the large-scale development of this type of building.

[0018] In the locking mechanism, this invention achieves multi-point synchronous locking through a spiral drive disc and a synchronous pusher. The four sets of bolts are evenly stressed, avoiding the stress concentration associated with traditional one-way clips. The spring-loaded reinforcement and retaining seat design of the drive ensure that the locking bolts do not fall out under dynamic loads. Furthermore, after locking, the pusher seat retracts, separating the bolt ends from the retaining seat. This allows for the lifting frame to be secured to the main steel structure without manual intervention.

[0019] At the same time, the present invention adopts an inverted construction method, which is to construct the main body of the steel structure from top to bottom in sections. This construction method does not require the use of large lifting machinery. It uses multiple sets of lifting frames to divide the main body of the steel structure into sections, lift them separately, and assemble them from top to bottom. Each section of the steel structure can be firmly connected to the lifting frame and assembled with the previous section after lifting until the main body of the structure is assembled. Finally, the lifting frame can be removed. The whole process is simple to operate, convenient to construct, and has a high safety factor. The main body of the lifting frame can be disassembled as a whole and reused, which reduces construction costs. It is particularly suitable for construction of buildings with large spans.

[0020] To sum up, the present invention relies on a group of lifting frames to lift the main building in sections, and uses a synchronous locking structure from the inside of the lifting frame to fix the main building on the lifting frame, systematically solving the core problems of poor stability, high cost, low efficiency and many safety hazards in the construction of large-span and ultra-high steel structure buildings, greatly improving the safety of large-span building main body construction and shortening the construction period. Its technical achievements can be widely used in ultra-large space building fields such as aerospace plants, nuclear power plant domes, and stadiums, promoting the development of industrial buildings in a higher, larger and safer direction, and having huge economic and social benefits.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments: Example 1. This example aims to provide an inverted lifting construction device for a large-span, ultra-high steel structure building, which is mainly used to realize the construction of ultra-high and large-span building main bodies. The existing construction methods generally use large-scale machinery for construction, which makes it difficult to effectively carry out the construction of the building, resulting in high construction costs, great construction difficulty and poor safety. Based on this, this example provides an inverted lifting construction device for a large-span, ultra-high steel structure building.

[0024] During specific implementation, a large-span and ultra-high steel structure building inverted lifting construction device includes a lifting frame 1, a lifting seat 2, a first lifting component 22, a locking component and a second lifting component 23; this embodiment only introduces a single lifting device. During specific construction, multiple groups of the construction devices are used for coordinated construction to form a lifting frame group. Under the action of the lifting frame group 1, the large-span building is inverted from top to bottom to achieve the smooth construction of the large-span steel structure body.

[0025] like Figure 1-3 As shown in the figure, the lifting frame 1 is arranged vertically and set at the corresponding construction point. The lifting frame 1 serves as the main load-bearing structure of the construction. The lifting frame 1 includes main columns 101, main beams 102, reinforcement beams, guide columns 103 and connecting columns 104; the main columns 101 are arranged vertically and are connected by the main beams 102 to form a frame structure in the direction. The middle part of the main beam 102 is connected to the guide column 103 through two connecting columns 104, thereby forming a guide area 106 on the side of the lifting frame 1; in this embodiment, there are four main columns 101, which are respectively arranged at the four corners of the square. The main columns 101 are thicker as a whole to withstand a larger load; the main beams 102 are connected to the main columns 101 in the transverse direction to form a frame structure. At the same time, according to the lifting height and size, X-shaped reinforcement beams can be constructed between the main columns 101 and the main beams 102 to ensure the stability of the main structure. At the same time, a guide area 106 is formed on the outside of the lifting frame 1 through the connecting beam, and the inner side of the guide area 106 is hollow and open; so as to facilitate the stable lifting of the lifting seat 2 and ensure the overall bearing capacity of the lifting seat 2; in addition, in this embodiment, a guide rail 105 is vertically arranged on the side wall of the square inner hole of the lifting frame 1 to provide positioning for the vertical lifting of the locking assembly.

[0026] Thus, this embodiment utilizes the structural configuration of the lifting frame 1, utilizing its square inner cavity, i.e., a centrally symmetrical square space, to provide vertical space for the locking assembly. The structural configuration of the guide area 106 also provides vertical positioning and limiting for the lifting seat 2, ensuring its lifting stability. The lifting seat 2 is also adaptively mounted on the lifting frame 1 and is provided with a guide block, which is provided with a suspension seat. The first lifting assembly 22 is connected to the suspension seat.

[0027] In the specific lifting structure, in this embodiment, the lifting seat 2 is mounted on the lifting frame 1, and the first lifting component 22 is arranged on the side of the top of the lifting frame 1 and is connected to the lifting seat 2 so that the lifting seat 2 can be lifted upward along the lifting frame 1; in this embodiment, the first lifting component 22 is a winch, and the winch is connected to the lifting frame 1 with a lifting rope. In this embodiment, the lifting frame 1 has four guide areas 106. According to construction requirements such as the weight of the main construction body, the number of winches is appropriately increased, that is, the number of side lifting points is increased, and the lifting seat 2 is lifted vertically upward, and the main body of the steel structure building is lifted upward synchronously.

[0028] In this embodiment, the locking assembly is used to fix the lifted steel structure building body and fix it on the lifting frame 1; in the specific implementation structure, the locking assembly includes a locking seat 8, a locking plate 4, a synchronous propulsion member, a driving member 15 and a locking member 16, and the second lifting assembly 23 is arranged in the middle of the top of the lifting frame 1, and the locking seat 8 is arranged inside the lifting frame 1 and is connected to the second lifting assembly 23, so that the locking seat 8 can be lifted and moved inside the lifting frame 1; structurally, four guide rails 105 are provided in the square inner cavity of the lifting frame 1, and a track groove is provided on the locking seat 8. The locking seat 8 is vertically adapted to be assembled in the square inner cavity and can be moved vertically along the guide rail 105.

[0029] The synchronous pushing member is arranged on the locking seat 8 and corresponds to the locking body of the lifting frame 1. The synchronous pushing member is synchronously extended and retracted, and the locking member 16 is moved closer to the locking position through the synchronous retracting structure.

[0030] The specific propulsion structure is implemented by a spiral drive disk in this embodiment. The synchronous propulsion member includes a shell 14, a propulsion disk 9, a propulsion seat 12 and a drive gear 13. A propulsion groove is provided on the shell 14, and the propulsion groove plays a guiding and positioning role. The propulsion disk 9 is rotatably set at the bottom of the shell 14 and is connected to the drive gear 13 through the ring gear 11. The drive gear 13 is rotatably set on the shell 14 and is connected to the drive motor. A spiral tooth structure is provided on the propulsion disk 9, and the propulsion seat 12 is mounted in the propulsion groove, and its bottom is engaged with the tooth structure; the driving member 15 is fixed on the propulsion seat 12; thus, through the above structure, the propulsion disk 9 is rotated by rotating the drive gear 13, and the propulsion disk 9 rotates using the spiral thread thereon to make the propulsion seat 12 move synchronously inward or outward along the propulsion groove.

[0031] In this embodiment, the middle of the shell is hollow, and the lifting rope of the second lifting component is connected to the middle lifting point of the locking seat through the hollow area. When implemented, the second lifting component can be a winch to lift the locking seat by winding the lifting rope.

[0032] The driving member 15 is mounted on the synchronous propulsion member and provides rotational power. The locking member 16 is fixed to the driving member 15. The locking member 16 is a bolt. The end of the driving member 15 is provided with a socket, which contains a spring. The front end of the bolt is clamped in the socket and reinforced by the spring. In this embodiment, one end of the bolt is a nut, which is adapted to be clamped in the socket, ensuring its structural stability and preventing it from falling off. The locking seat 8 is lifted using the second lifting assembly 23. After construction reaches the corresponding point, the drive motor is started to synchronously move the propulsion seat 12 outward. At the same time, the driving member 15 is started, causing its bolt to rotate and screw into the preset connection hole. The steel structure body is connected to the lifting frame 1 using the bolt.

[0033] The lower portion of the steel structure is provided with a side seat 3, to which a locking plate 4 is fixed, corresponding to the locking body. The locking member 16 penetrates the locking body and the locking plate 4, and after the steel structure is lifted, it is fixed to the lifting frame 1. In practice, a nut is welded to the outer side of the locking plate 4 and the locking body. One side of the locking bolt is driven to rotate by the driving member 15 and screwed into the nut, fastening the side seat to the lifting frame 1 via four bolts.

[0034] Based on the above structure, this embodiment also provides a large-span and ultra-high steel structure building lifting construction method, including the following steps: Step 1: Review the construction area according to the design drawings, further optimize and determine the fixed position of the lifting frame 1, and lay out the construction at the fixed position; Step 2: Excavate a foundation pit in the construction layout area, tie steel bars in the foundation pit, reserve the lifting frame 1 in it, connect the lifting frame 1 to the steel bars through tying wires and reinforcement plates, and then pour concrete; use a segmented and multi-section construction method to lift the lifting frame 1 from the bottom to the preset height; Step 3: Sleeve the lifting seat 2 onto the outside of the lifting frame 1, sleeve the locking seat 8 onto the inside of the lifting frame 1, and install the locking assembly on the locking seat 8; Step 4: Fix the top plate on the top of the lifting frame 1, then fix the first lifting assembly 22 and the second lifting assembly 23 on the top plate. The first lifting assembly 22 and the second lifting assembly 23 respectively extend the lifting rope downward and connect them to the lifting base 2 and the locking base 8; Step 5: Assemble the main steel structure building in the top area between the lifting frames 1 and fix the main steel structure building on each lifting seat 2. Start the first lifting assembly 22 and the second lifting assembly 23 to lift the lifting seat 2 and the locking seat 8, and at the same time drive the main steel structure building upward to the corresponding height; Step 6: Start the locking assembly and drive the locking member 16 into the lifting frame 1 and the locking piece 4 from the inside to fix the steel structure building body on the lifting frame 1; Step 7: Reverse drive the locking assembly to disengage the driving member 15 from the locking member 16, reverse drive the first lifting assembly 22 and the second lifting assembly 23 to separate the lifting base 2 from the main body of the steel structure building, and lower the locking base 8; Step 8: Repeat steps 5 to 7 to lift the main body of the steel structure building to the standard height; Step nine, connecting the upper and lower steel structure building bodies by bolts to form the main structure of the steel structure building; Step 10: Finally, remove the lifting frame 1.

[0035] During implementation of this embodiment, the top-floor building structure 17 is first constructed. After its lower portion is secured to the lifting frame 1, the next-floor building structure 18 is constructed, followed by the next-floor building structure 19, and so on, sequentially and downwardly, to achieve a lifted, inverted construction of the building structure. This embodiment utilizes a group of lifting frames to lift the building structure in sections, and secures the building structure to the lifting frames from within using a synchronous locking structure. This systematically addresses the core issues of poor stability, high cost, low efficiency, and numerous safety hazards associated with the construction of large-span, ultra-high steel structures, significantly improving the safety of large-span building structure construction and shortening the construction period.

[0036] Example 2: In order to facilitate assembly, the side seats are provided with a snap-fit assembly structure.

[0037] In this embodiment, the side seat comprises a first assembly sleeve and a second assembly sleeve, which are joined together to form the side seat. A steel structure is fixedly connected to the side of the side seat. Specifically, the first and second assembly sleeves are both U-shaped structures, which are interlocked and assembled on the lifting frame 1. After being assembled through the connecting seat 6 and fixed together by bolts, they form a closed square structure. This embodiment is suitable for one or two lifting points, but for four lifting points, a four-assembly sleeve assembly is used.

[0038] At the same time, a docking seat is provided on the side of the steel structure building. The docking seat is fixed to the side of the side by bolts in a detachable manner. In order to facilitate the separation of the side seat from the main steel structure at a later time, the docking seat includes an upper docking seat 20 and a lower docking seat 21. The lower part of the upper docking seat 20 is provided with a positioning block, and the upper part of the lower docking seat 21 is provided with a positioning groove. The positioning block and the positioning groove are adapted to be assembled together and provided with corresponding connection holes. Bolts are applied in the connection holes to fix the steel structure together.

[0039] Example 3: This embodiment further provides a synchronous propulsion member.

[0040] The synchronous propulsion element comprises multiple sets of pneumatic cylinders, which operate synchronously and provide linear driving force. The locking element 16 is a bolt. The end of the driver 15 is provided with a retaining seat, which contains a spring. The front end of the bolt is retained within the retaining seat and reinforced by the spring. With this structure, the pneumatic cylinders drive the propulsion seat 12, causing the driver 15 on it to move with the bolt toward the locking position.

[0041] In this embodiment, the driving member 15 can be an electric drill, and the electric motor is connected to the controller. By pre-configuring a distance sensor on the locking seat 8, the distance between the locking seat 8 and the top plate is detected, and a start signal is generated to stop the second lifting component 23 (i.e., the second winch). Then, each electric drill is started through the controller, and then each cylinder is activated and pushed forward to tighten the bolt locking piece 4 and the locking body.

[0042] In the above embodiment, the locking body adopts the main column 101, which has a strong structural strength and can withstand large loads. The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. The basic concept of the present invention is to rely on a group of lifting frames to lift the main structure of the building in sections, and to secure the main structure of the building to the lifting frames from the inside using a synchronous locking structure. This systematically solves the core problems of poor stability, high cost, low efficiency, and multiple safety hazards in the construction of large-span, ultra-high steel structures.
