Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a temporary hoisting support frame. Background Technology

[0002] Space frame structures are widely used in large-span buildings, such as stadiums, exhibition halls, and multi-purpose halls, due to their advantages such as good spatial stress performance, lightweight structure, high stiffness, good seismic performance, and fast construction speed. Common space frame structure forms include welded ball joint square pyramids and bolted ball joint square pyramids.

[0003] The traditional installation methods for space frame structures mainly include high-altitude assembly and ground-based assembly and hoisting.

[0004] The high-altitude assembly method involves transporting the space frame members and nodes to the designed location and assembling and welding them one by one on an erected high-altitude scaffold. The main disadvantages of this method are: it requires extensive high-altitude work, posing high safety risks; assembly accuracy is greatly affected by human factors; construction speed is slow; and for complex or large-span space frames, the erection of the high-altitude assembly scaffold is difficult and costly; and the quality of high-altitude welding is difficult to control, easily leading to welding defects.

[0005] The ground assembly and hoisting method involves assembling the space frame structure as a whole on the ground and then using lifting equipment to hoist it to the designed position. Depending on the type of lifting equipment, it can be further divided into the multi-crane hoisting method: using multiple cranes to lift simultaneously, suitable for lighter space frame structures; and the sliding method: after assembling the space frame structure on the ground, using sliding equipment to move it below the designed position before hoisting. Existing hoisting methods have certain requirements for site space and make it difficult to precisely control the synchronization of multiple lifting points. Utility Model Content

[0006] To address the aforementioned issues, this utility model provides a temporary hoisting support frame. This frame allows columns to pass through the welded space frame structure and stabilize it on the ground. The lifting mechanism between the columns is fixedly connected to the hoisting points of the space frame structure. By setting up multiple temporary hoisting support frames and connecting them according to the pre-set hoisting points on the space frame structure, the overall hoisting of the space frame structure can be completed.

[0007] This utility model provides a temporary hoisting support frame, the specific technical solution of which is as follows:

[0008] This includes lifting beams, columns, and lifting mechanisms;

[0009] The column has two vertical connections on the same side at both ends of the lifting beam;

[0010] The lifting mechanism includes a hydraulic lifting device, a suspension line, and a lifting structure. The hydraulic lifting device is mounted on the lifting beam and connected to the lifting structure via the suspension line.

[0011] The suspension line is connected to the lifting structure, and the lifting structure is fixedly connected to the pre-arranged lifting points of the space frame structure to be lifted.

[0012] Based on this frame structure, the columns can pass through the "mesh holes" of the space frame structure, so that the middle lifting mechanism can correspond to the welding nodes of the space frame structure, i.e., the hoisting points. By fixing the lifting mechanism to the corresponding hoisting points, the overall lifting of the space frame structure can be achieved.

[0013] Furthermore, the lifting structure includes a lifting end and a connecting end, wherein the lifting end and the connecting end are fixedly connected;

[0014] The connecting end is fixedly connected to the spherical structure corresponding to the pre-arranged hoisting point of the space frame structure;

[0015] The lifting end is connected to the lifting line.

[0016] Furthermore, the connecting end includes two first plates and second plates that are fixedly connected perpendicularly to each other in the middle. The bottom of the first plate and the second plate that are connected to the lifting point is an arc-shaped structure, and the curvature of the arc-shaped structure is adapted to the contact part of the spherical structure corresponding to the lifting point.

[0017] The welding points of each truss in the space frame structure are spherical. This structural design of the connection end allows for better contact and connection with the hoisting point, ensuring improved connection stability.

[0018] Furthermore, the connecting end is fixedly connected to the lifting end via a stabilizing plate;

[0019] The tops of the first plate and the second plate are perpendicularly connected to the end face of the stabilizing plate, and the lifting end is perpendicularly fixedly connected to the other end face of the stabilizing plate.

[0020] The installation of stabilizing plates ensures that both the lifting end and the connecting end are fixedly connected via stabilizing plates, guaranteeing a balanced lifting force at the contact points during the lifting process and ensuring the stability of the main lifting structure.

[0021] Furthermore, the lifting end includes a lifting block and a lifting plate, and the lifting block is fixedly connected to the lifting plate.

[0022] Furthermore, at least two lifting plates are provided, symmetrically arranged on one side of the lifting block parallel to the lifting through hole;

[0023] One end of the hoisting plate is vertically and fixedly connected to the stabilizing plate.

[0024] The lifting end is connected to the stabilizing plate via a lifting plate to prevent the lifting end from swaying at the end of the lifting line, thus ensuring the stability of the lifting.

[0025] Furthermore, the lifting block is provided with a lifting through hole, the lifting line passes through the lifting through hole, and a lifting limit block is provided at the tail end of the line passing through the lifting through hole. The lifting line is fixedly connected to the lifting limit block, and the size of the lifting limit block is larger than that of the lifting block.

[0026] Furthermore, the planes on which the lifting plates are positioned relative to each other are perpendicular to the planes on which the first plate or the second plate is located.

[0027] This structure ensures that the lifting structure can withstand greater forces, thus guaranteeing the stability of its main body.

[0028] Furthermore, the lifting beam is located at the connection end of the column, and a reinforcing rod is provided around the column, the reinforcing rod being perpendicular to the column; the lifting beam is also provided with a stiffening plate.

[0029] By installing stiffening plates and reinforcing rods, the structural strength, stiffness, and stability at the connection between the lifting beam and the column are enhanced to resist local stress, prevent buckling or deformation, and improve the overall load-bearing capacity.

[0030] Furthermore, the bottom of the column is provided with a reinforcing member, which includes a diagonal bar and a horizontal bar. One end of the diagonal bar is connected to the column to form a triangular structure, and the horizontal bar is fixedly connected between the diagonal bar and the column.

[0031] The reinforcement components ensured the stability of the bottom of the entire support frame, guaranteeing the safety of the overall lifting process.

[0032] The beneficial effects of this utility model are as follows:

[0033] This utility model designs a temporary hoisting support frame. The main structure includes a lifting beam fixedly connected to columns at both ends. The columns pass through the space frame structure and are fixed to the ground with the reinforcement at the bottom. A hydraulic lifting device is installed on the lifting beam and connected to the lifting structure through a hoisting line. The lifting structure is located between the two columns and connected to the spherical welding point of the space frame structure, which is planned as the hoisting point. Multiple support frames are respectively set and connected to the corresponding hoisting points planned on the space frame structure to realize the overall lifting of the entire space frame structure. After the lifting is completed, the frame is dismantled. Attached Figure Description
