Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a rapid installation system for cup-shaped columns. Background Technology

[0002] With the rapid development of society and economy and the continuous innovation of science and technology, steel structure construction technology is constantly evolving. Among them, large-span portal frame structures, due to their unique structural advantages and wide application, are widely used in large exhibition centers, stadiums, and large-span industrial plants, becoming an indispensable part of modern architecture. As the main load-bearing component of the portal frame structure, the quality of its installation directly affects the overall installation quality of the steel structure project, playing a crucial role. Currently, how to achieve fast, efficient, and high-quality installation of portal columns has become a hot topic of concern and research for engineering technicians.

[0003] Currently, the installation of cup-shaped columns in large-span portal frame structures mostly uses hydraulic jacks to control the verticality during installation, and steel column positions are controlled by spot welding of steel bars and the addition of steel wedges. Elevation control lines are pulled down from the top of the column to control the top surface elevation, and guy ropes are used to stabilize and reinforce the steel column in four directions. Although this can ensure the elevation, verticality, and plane coordinates of the cup-shaped column, the installation speed is slow, and it is difficult to complete the installation and correction of the cup-shaped column quickly and efficiently. This is not conducive to the installation of large-volume cup-shaped columns, the construction period is long, the amount of tooling and materials used is large, and special personnel need to be arranged to remove the steel wedges when pouring concrete for the cup-shaped foundation, resulting in a large labor input and hindering the cost reduction and efficiency improvement of the project.

[0004] Therefore, how to create a device that is simple in structure, easy to install and disassemble, low in cost, yet efficient and high-quality for the rapid installation of cup-shaped columns has become a key focus for engineering technicians. Utility Model Content

[0005] The purpose of this invention is to provide a rapid installation system for cup-shaped columns, which solves the problem of rapid, efficient, and high-quality installation of cup-shaped columns.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rapid installation system for a cup-shaped column includes a cup-shaped column, a cup-shaped foundation, and a hoisting system. The top of the cup-shaped column is hoisted into the cup-shaped foundation by the hoisting system, and the bottom of the cup-shaped column is adjusted by an adjustable device to align with the installation position on the cup-shaped foundation.

[0008] The column reinforcement and adjustment device includes a frame, an upper clamping assembly, and a lower adjustment assembly. The frame is detachably installed on the cup mouth base. At least four sets of the upper clamping assemblies are adjustablely arranged at the top of the frame, and at least four sets of the lower adjustment assemblies are adjustablely arranged at the bottom of the frame. After the at least four sets of lower adjustment assemblies are adjusted to align the cup mouth column, they are temporarily clamped and fixed by the at least four sets of upper clamping assemblies.

[0009] Preferably, the frame is a hexahedral frame structure composed of eight crossbeams and four legs. The hexahedral frame structure is fixedly installed on the cup-shaped base. Each of the four crossbeams on the upper layer of the frame is provided with a set of upper clamping components, and each of the four crossbeams on the lower layer of the frame is provided with a set of lower adjustment components.

[0010] Preferably, the upper clamping assembly includes a screw and a nut seat. The nut seat is detachably installed at the elongated hole of the crossbeam by bolts. The screw is threaded into the nut seat, and the top end of the screw abuts against the side wall of the bottom flange of the cup-mouth column.

[0011] Preferably, the lower adjustment component is a hand-cranked flat-bottomed jack, with a top plate at the top of the hand-cranked flat-bottomed jack, the top plate abutting against the side wall of the bottom flange of the cup-mouth column.

[0012] Preferably, an L-shaped hook is fixedly installed at the bottom of the hand-cranked flat-bottomed jack. When the top of the hand-cranked flat-bottomed jack abuts against the side wall of the bottom flange of the cup-mouth column, the L-shaped hook is horizontally hooked onto the crossbeam.

[0013] Preferably, one or more crossbeams in the lower layer of the frame are movable crossbeams connected to adjacent crossbeams by bolts; one or more crossbeams in the upper layer of the frame are also movable crossbeams connected to adjacent crossbeams by bolts; and the support legs are welded to the crossbeams.

[0014] In this invention, the upper clamping assembly is used to adjust the horizontal position of the cup-shaped column, and the upper clamping assembly on the crossbeam adjusts the verticality of the cup-shaped column. The double reinforcement measures of the upper clamping assembly and the upper clamping assembly ensure that the cup-shaped column does not overturn during installation, improving its stability and providing convenient conditions for the subsequent hoisting of the portal frame beam. The cup-shaped column can be stably reinforced without the need for steel wedges around it, reducing labor input and shortening the construction cycle. It has the potential for large-scale promotion and application in the field of steel structure engineering. It also facilitates the pouring of concrete for the cup-shaped foundation, improves the installation accuracy of the cup-shaped column, and reduces the occurrence of safety accidents during hoisting, preparing for the subsequent hoisting of the portal frame beam.

[0015] After the cup-shaped column is installed, unscrew the four sets of bolts connecting the upper and lower crossbeams on one side, and remove the frame from the cup-shaped foundation for easy turnover and reuse.

[0016] This utility model has a simple structure and is easy to process and manufacture. The steel required is all commonly used in processing plants. The process of installation and disassembly is simple and quick. The column reinforcement and adjustment device can quickly install the cup-mouth column, and the adjustment process is more convenient. Because it requires fewer personnel, it performs outstandingly in terms of cost saving and greatly improves the installation efficiency and construction quality of the cup-mouth column.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-2 The diagram illustrates a rapid installation system for cup-shaped columns, comprising a cup-shaped column 1, a cup-shaped foundation 2, and a hoisting system. The top of the cup-shaped column 1 is lifted into the cup-shaped foundation 2 using the hoisting system, while the bottom of the column 1 is adjusted and aligned with its installation position on the cup-shaped foundation 2 using a column reinforcement and adjustment device 3. In this example, the specifications of the cup-shaped column 1 mainly include: H800×350×12×20, H800×350×12×25, H600×350×12×30, H600×350×12×20, and solid-web steel columns with irregularly shaped combined cross-sections. The hoisting system specifically uses a truck crane.

[0022] The column reinforcement and adjustment device 3 includes a frame 30, upper clamping components 31, and lower adjustment components 32. The frame 30 is detachably mounted on the cup-mouth base 2. At least four sets of upper clamping components 31 are adjustablely installed on the top of the frame 30, and at least four sets of lower adjustment components 32 are adjustablely installed on the bottom of the frame 30 to accommodate cup-mouth columns of different specifications and sizes. After the at least four sets of lower adjustment components 32 are adjusted to align the cup-mouth column 1, they are temporarily clamped and fixed by the at least four sets of upper clamping components 31.

[0023] The frame 30 is a hexahedral frame structure consisting of eight crossbeams 300 and four legs 301. The hexahedral frame structure is fixed on the cup-shaped foundation 2 by anchor bolts. Each of the four crossbeams 300 on the upper layer of the frame 30 is provided with an upper clamping assembly 31, and each of the four crossbeams 300 on the lower layer of the frame 30 is provided with a lower adjusting assembly 32.

[0024] The upper clamping assembly 31 includes a screw 310 and a nut seat 311. The nut seat 311 is detachably installed at the elongated hole of the crossbeam 300 by bolts. The screw 310 is threaded into the nut seat 311, and the top of the screw 310 abuts against the bottom flange sidewall of the cup-mouth column 1.

[0025] The lower adjustment component 32 is a hand-cranked flat-bottomed jack, with a top plate at the top of the hand-cranked flat-bottomed jack, which rests against the bottom flange side wall of the cup-mouth column 1.

[0026] An L-shaped hook is fixedly installed at the bottom of the hand-cranked flat-bottomed jack. When the top of the hand-cranked flat-bottomed jack abuts against the side wall of the bottom flange of the cup-mouth column 1, the L-shaped hook is horizontally hooked onto the crossbeam 300.

[0027] One or more crossbeams 300 on the lower layer of frame 30 are movable crossbeams, connected to adjacent crossbeams 300 by bolts. One or more crossbeams 300 on the upper layer of frame 30 are also movable crossbeams, connected to adjacent crossbeams 300 by bolts. Support legs 301 are welded to the crossbeams 300.

[0028] The specific steps for quick installation of the cup-shaped column are as follows:

[0029] (1) The inner wall of the installation position of the cup mouth foundation 2 must be roughened and cleaned first, and the garbage, water, dust and other debris inside the cup mouth must be completely removed. The longitudinal and transverse positioning cross lines for the installation of the cup mouth column 1 should be marked on the cup mouth foundation 2 by measuring instruments, and the bottom elevation of the cup mouth foundation 2 should be measured to ensure the accuracy of the elevation when the cup mouth column 1 is installed.

[0030] (2) Place the column reinforcement and adjustment device 3 on the cup mouth foundation 2, loosen the four screws 310, and insert the reserved cup mouth column 1 into the installation position;

[0031] (3) Lift the cup-mouth column 1 to the installation position using a truck crane, and manually and slowly position it. Place the bottom surfaces of the four hand-cranked flat-bottomed jacks close to the cup-mouth column 1. The L-shaped hooks of the hand-cranked flat-bottomed jacks should be pressed against each other and close to the crossbeam 300 of the lower layer of the frame 30. Adjust the coordinate position of the cup-mouth column by manually cranking the handles of each hand-cranked flat-bottomed jack so that the longitudinal and transverse positioning cross lines are aligned with the center line of the cup-mouth column.

[0032] (4) After the coordinate position is adjusted, tighten the four screws and press them against the side wall of the cup mouth column. Prepare two theodolites and place them on the north and east sides of the cup mouth column respectively. Measure the center line of the cup mouth column. If the longitudinal center line is aligned, the cup mouth column is vertical. If it is not aligned, the cup mouth column needs to be adjusted. Adjust the verticality of the cup mouth column by adjusting the length of the screw threads until the center line of the cup mouth column in both directions is aligned with the center line of the theodolite.

[0033] (5) After the plane position, verticality and elevation meet the requirements, check whether each fastener is firm. After confirming that there are no errors, release the crane hoisting ropes. The cup-mouth column installation is now complete.

[0034] (6) After the portal frame structure forms an overall stable system, concrete is poured inside the cup-shaped foundation. Before the concrete reaches its final set state, the column reinforcement and adjustment device can be removed.

[0035] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
