Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, and more specifically, it relates to a detachable storage rack for box girder steel cage lifting devices. Background Technology

[0002] In the production process of precast box girders for high-speed railways, after the reinforcing cage is tied and formed on the overall binding platform, a large reinforcing cage hoist is needed to lift it as a whole onto the box girder formwork. This hoist is huge, typically 34 meters long, about 13.35 meters wide, and weighs about 22 tons, and must be safely stored when not in use.

[0003] Currently, the common storage method is to allocate a separate area within the beam yard for flat or upright storage. This method occupies a significant amount of valuable construction land and reduces site utilization efficiency. To save ground space, some beam yards use independent support columns above the inner formwork of the box girder to store the scaffolding. However, this support structure, composed of multiple independent columns, lacks effective connections between the columns, resulting in poor overall integrity and insufficient structural stability. It is particularly prone to swaying or even overturning under wind loads, posing significant safety hazards. Furthermore, these support structures often employ welding or simple fixing methods, making disassembly and assembly inconvenient and hindering reuse and inter-project turnover. Utility Model Content

[0004] The purpose of this invention is to provide a detachable storage rack for box girder reinforcement cage lifting devices, so as to solve the problems of large storage space, poor structural stability, many safety hazards and non-reusability of existing lifting devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A detachable storage rack for box girder reinforcement cage lifting devices includes:

[0007] Multiple support columns, each with a connecting flange at its bottom and fixed to the foundation piles by high-strength bolts;

[0008] A truss connection system, comprising longitudinal trusses and transverse trusses, wherein the longitudinal trusses are arranged along the length direction of multiple supporting columns, and the transverse trusses are arranged along the width direction of the supporting columns, and the truss connection system is detachably connected to the supporting columns by means of node plates and high-strength bolts;

[0009] The guy rope system includes multiple steel wire ropes, one end of which is fixed to the top node of the truss connection system, and the other end is anchored to a ground anchor or concrete pier.

[0010] A top support platform is located on top of multiple support columns and is used to support the steel cage hanger.

[0011] Preferably, the supporting column is made of H-beam or box-beam steel, and the column height ensures that the bottom of the hanger and the top of the inner mold below maintain a sufficient safety clearance.

[0012] Preferably, the top support platform is composed of multiple short steel beams fixed by bolts and forms a grid structure; multiple storage cavities are formed in the top support platform for storing the rebar cage lifting equipment.

[0013] Preferably, a fastener is also provided at the node where the cavity is stored, and the fastener is any one of the fixing tools such as chain, buckle, or clamp.

[0014] Preferably, the top of the top support platform is also provided with a rain shelter.

[0015] Preferably, the foundation piles are reinforced concrete independent foundations, with a flange pre-embedded at the top of each foundation for bolt connection with the supporting column.

[0016] Preferably, the side wall of the supporting column is integrally provided with a first support plate; the bottom of the truss connection system is integrally provided with a second support plate; and a support arm is provided between the first support plate and the second support plate by bolts.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) The storage rack uses a truss connection system to connect multiple support columns into a whole, and is reinforced with a guy rope system to form a stable spatial force frame, which significantly improves the overall stiffness and resistance to lateral forces of the structure, effectively avoids the risk of swaying and overturning caused by wind load or accidental collision, and provides a safe and reliable storage guarantee for the large steel cage hanging frame weighing up to 22 tons, greatly improving the inherent safety level of the construction site.

[0019] (2) The main connections of the overall structure of this storage rack are made of high-strength bolts to achieve detachable connection, abandoning the traditional welding fixing method. This allows the storage rack to be quickly disassembled into standardized components after the project is completed, which is convenient for transportation and storage. It can also be completely transferred to the next project for repeated installation and use, which greatly improves the utilization rate of tooling and equipment, reduces resource waste, and reduces the equipment investment cost of subsequent projects. This is in line with the development concept of green construction and circular economy. Attached Figure Description

[0026] Detailed implementation method

[0027] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0029] like Figures 1-4 As shown in the figure, this embodiment provides a detachable storage rack for box girder reinforcement cage lifting equipment. Its structural design fully integrates technological innovation and engineering practicality, effectively solving the safety, efficiency and cost problems in the storage of large lifting equipment.

[0030] First, multiple foundation piles 4 are poured at designated locations in the beam yard. The foundations are C30 reinforced concrete independent foundations to ensure the bearing capacity meets requirements. Pre-embedded flanges with holes are pre-installed at the top of each foundation for subsequent connections. Support columns 1, made of Q355B grade H-beams, are hoisted into place, aligning their bottom connecting flanges 10 with the pre-embedded flanges on the foundation piles 4, and then secured with M24 high-strength bolts. This connection method is not only convenient to install but also provides reliable vertical support for the entire structure. It is also fully disassembled, facilitating later overall relocation and reuse, significantly reducing tooling amortization costs.

[0031] Subsequently, the prefabricated truss connection system 7 was assembled on-site. This system consists of longitudinal and transverse trusses welded from angle steel, securely connected to each supporting column 1 via node plates 11 and M20 high-strength bolts, forming a spatial grid frame. To enhance connection rigidity, a first support plate 81 is welded to the side wall of the supporting column 1, and a second support plate 82 is installed at the bottom of the truss connection system 7. An oblique support arm 83 is bolted between the two, forming a triangular stable structure. This integrated design allows the originally isolated columns to share the load collaboratively, significantly improving the overall rigidity and stability of the structure, effectively resisting lateral forces such as wind loads, fundamentally avoiding the safety hazard of traditional independent columns easily overturning, and ensuring the absolute safety of the 22-ton steel cage suspension during storage.

[0032] At the top of the truss connection system 7, a top support platform 2, composed of multiple short H-shaped steel beams bolted together, is installed. This platform has a grid structure, forming multiple regular storage cavities 200, the dimensions of which precisely match the positions of the support legs of the steel cage hanger. After the hanger is in place, chains, buckles, clamps, etc., can be used as fasteners 6 at the four corners of the storage cavities 200 for temporary fixation to prevent slippage due to vibration or external forces, further improving the safety of use.

[0033] To further enhance wind resistance, guy rope systems 5 are installed at the top nodes of the four corners of the truss connection system 7. The guy ropes are diagonally pulled by steel wire ropes, and the other end is anchored to the concrete pier on the ground by turnbuckles. The tightness can be adjusted as needed to ensure the stability and reliability of the structure under various working conditions.

[0034] Finally, a rain shelter 3, constructed of a light steel frame and color steel plates, is installed above the top support platform 2. This design not only protects the long-term stored steel cage hangers from sun and rain corrosion, extending the equipment's lifespan, but more importantly, its coverage extends to the inner formwork of the box girder below, effectively preventing rainwater erosion that could cause the release agent to be lost. This ensures the demolding quality and concrete appearance of the precast box girder, avoiding quality defects and rework losses, and achieving the comprehensive benefits of "one item serving multiple purposes".

[0035] In summary, this embodiment constructs a safe, stable, and detachable three-dimensional storage system through the synergistic action of the supporting column 1, truss connection system 7, guy rope system 5, and top bearing platform 2. By storing the hangers above the inner formwork, it significantly saves ground space and optimizes the beam yard layout; the all-bolted connection design enables rapid installation and cross-project turnover, improving tooling utilization; and multiple protective measures ensure the quality of equipment, molds, and construction, fully demonstrating the outstanding progress of this invention in safety, economy, and functionality.
