Description

Technical Field

[0001] This utility model relates to the field of bridge substructure construction technology, and more specifically to a steel cage hanger. Background Technology

[0002] During the construction of bridge pile foundations and cylindrical piers, the conventional construction process for lowering the pile foundation reinforcement cage and installing the cylindrical pier reinforcement cage involves dividing the reinforcement cage into multiple sections for hoisting and installation. Straight threaded sleeves are used to connect or weld each section of the reinforcement cage to form a complete reinforcement cage framework. After a crane lifts a section of the reinforcement cage and lowers it into the pile hole or connects the column reinforcement cage to the pile foundation reinforcement cage, structural steel is used as a support rod (the specific dimensions of the structural steel are determined based on stress calculations). The support rod passes horizontally through the reinforcement cage, forming a fulcrum to bear the weight of that section and stabilize the cage. Then, the crane lifts the next section of the reinforcement cage and connects it to the previous section.

[0003] However, firstly, when using conventional construction techniques for connecting rebar cages, the support rods must pass through the main body of the cage. When the main reinforcing bars (longitudinal bars) are densely packed and spaced closely, the support rods often cannot pass through properly, requiring local adjustments to the spacing between the main bars. Secondly, passing through the support rods requires manual labor, which is difficult when the steel sections are large or heavy. Furthermore, using steel section supports, due to conflicting support plane positions, only 1-2 supports can be installed in one direction, resulting in the rebar cage not being stably suspended on the support rods, hindering connection work. Moreover, because there are fewer support rods, each rod experiences greater bending force, making it prone to bending deformation or breakage, which is detrimental to reuse.

[0004] Therefore, how to provide a simple structure that helps to stably suspend the steel cage is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides a steel cage hanger, which aims to solve the above-mentioned technical problems.

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

[0007] A steel cage hanger, comprising:

[0008] Support rods, there are multiple support rods, and the multiple support rods are connected end to end to form a square hanging base;

[0009] The suspension plate is provided in multiple ways, and each of the multiple suspension plates is fixed to the bottom surface of multiple support rods in a one-to-one correspondence. The suspension plate has suspension holes on its panel for threading suspension steel wire ropes.

[0010] Fixed pulleys, there are multiple fixed pulleys, and each of the multiple fixed pulleys is fixed to one of the four corners of the top surface of the square lifting base so that the lifting steel wire rope can be threaded through.

[0011] The beneficial effects of this utility model are that the suspension plate is connected to the reinforcing ring of the steel cage by a suspension wire rope through the suspension hole, and the lifting seat is connected to the lifting machinery by a lifting wire rope through the fixed pulley. The steel cage is lifted by a multi-point suspension method, making the lifting process more stable.

[0012] Preferably, it further includes a first connecting rod and a second connecting rod; the first connecting rod and the second connecting rod are arranged perpendicularly to each other to form a cross, the cross is located at the center of the square hanging base and its ends are fixed to the side wall of the support rod. The hanging base is supported by the first connecting rod and the second connecting rod, which can ensure the structural strength and stability of the hanging base.

[0013] Preferably, the first connecting rod is located above the second connecting rod, and a lifting ring is fixed to the center of the top surface of the first connecting rod. The lifting ring allows the lifting point to be concentrated in the center of the frame, ensuring stability during the lifting process and preventing tilting and instability.

[0014] Preferably, the first connecting rod is an I-beam, and the second connecting rod is a channel steel. This ensures that the connecting rods have sufficient mechanical strength to support the hanger.

[0015] Preferably, the support rod is made of channel steel of not less than 16# to ensure the load-bearing performance of the support rod.

[0016] Preferably, there are two hanging plates, and each of the two hanging plates is fixed with a suspension pulley relative to the inner wall of the suspension hole. The suspension pulleys assist in threading the suspension wire rope, ensuring the parallel stability of the wire rope during the hoisting process and guaranteeing the smooth hoisting of the reinforcing cage.

[0017] Preferably, the support rod has multiple bolt holes on both sides, and the two lifting plates are symmetrically arranged on both sides of the support rod and bolted to the bolt holes. By bolting the lifting plates to the bolt holes at different positions, the hoisting operations of steel cages with different diameters can be met.

[0018] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a steel cage hanger, which effectively ensures the stability of the steel cage during the hoisting process by means of multi-point suspension. It has a simple structure, low manufacturing cost and can be reused, thus effectively ensuring the installation efficiency of the steel cage. Attached Figure Description

[0029] Fixed pulleys 6, there are multiple fixed pulleys 6, and multiple fixed pulleys 6 are fixed one to one at the four corners of the top surface of the square hanging base so that the lifting steel wire rope can be threaded through.

[0030] like Figure 1 As shown, in this embodiment, there are four support rods. The four support rods are welded and fixed at both ends to form a square hanging base. There are four hanging plates. The four hanging plates are arranged radially from the center along the bottom surface of the hoisting to ensure the uniform distribution of the lifting points of the steel cage.

[0031] Fixed pulleys are fixed at the four corners of the top surface of the lifting platform. The steel cage is suspended by the hanging plate and the suspension wire rope. The lifting equipment is connected to the fixed pulleys and the suspension wire rope for lifting operations.

[0032] To further enhance the above technical solution, ensure the strength of the hoisting, and prevent deformation during hoisting, a first connecting rod 3 and a second connecting rod 4 are also included. The first connecting rod 3 and the second connecting rod 4 are arranged perpendicularly to each other to form a cross. The cross is located at the center of the square hoisting seat and its end is fixed to the side wall of the support rod 1.

[0033] The first and second connecting rods are welded together to form a cross, which supports the interior of the square hanger. The center of the cross is the center point of the hanger. The cross prevents the hanger from deforming, increasing its reusability and service life.

[0034] To further optimize the above technical solution, the first link 3 is located above the second link 4, and a lifting ring 5 is fixed in the middle of the top surface of the first link 3.

[0035] The lifting rings ensure that the lifting points are concentrated at the center of the lifting platform, guaranteeing a stable and effective lifting process.
