Abstract
Description
Technical Field
[0001] This application relates to the field of steel reinforcement cages for building tunnel segments, and in particular to a storage and inspection table for steel reinforcement cages for tunnel segments. Background Technology
[0002] In the construction of shield tunnel segments, precast concrete segments, as a key component of the tunnel structure, have a direct impact on the overall progress of shield construction due to their industrialized production efficiency. As a complex and standardized precast component, the temporary storage and stacking of the steel reinforcement cages in the industrialized production of shield tunnel segments is crucial for controlling production efficiency and product quality. However, existing storage racks for segment steel reinforcement cages have the following main problems:
[0003] Limited size adaptability: Traditional storage racks use a welded, fixed frame structure, with fixed parameters such as the spacing, curvature, and height of the supporting beams. This makes them unable to flexibly adapt to rebar cages of different diameters, curvatures, and lengths. This necessitates factories customizing storage racks for different specifications of rebar cages, thus increasing equipment investment costs.
[0004] Uneven load-bearing capacity: As an arc-shaped thin-walled space frame structure, when steel cages are directly stacked, the bottom layer of steel cages has fewer contact points with the storage rack, making them prone to plastic deformation due to localized stress concentration, such as arc surface collapse or radial twisting. These problems not only affect the finished quality of the steel cages but also reduce the product qualification rate.
[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0009] To solve the above-mentioned technical problems, this application provides the following technical solution:
[0010] A segment reinforcement cage storage and inspection platform is provided, the segment reinforcement cage storage and inspection platform includes: a support plate and a plurality of adjustment components disposed at the lower end of the support plate;
[0011] The support plate has elastic bending capability and is evenly distributed with several bolt holes;
[0012] The adjustment assembly includes a base, a screw, a locking nut, and a support nut. The base is fixedly installed on the ground and is equipped with a screw sleeve. One end of the screw extends into a bolt hole of the support plate, and the other end is movably inserted into the screw sleeve. The locking nut is connected to the screw and fixes the screw in the bolt hole of the support plate. The support nut is connected to the screw and supports the upper end of the screw sleeve, and is configured to adjust the height of the support plate.
[0013] Several of the adjustment components are connected to bolt holes at different positions on the support plate via their respective screws to adjust the curvature of the support plate so that it matches the curvature of the segment reinforcement cage.
[0014] In some embodiments, the adjustment assembly includes a central adjustment assembly and at least two sets of side adjustment assemblies; the screw of the central adjustment assembly is connected to the bolt hole in the middle of the support plate; the side adjustment assemblies are symmetrically distributed around the central adjustment assembly and are connected to the bolt holes at both ends of the support plate through their respective screws.

Detailed Implementation
[0030] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.
[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0032] Existing storage racks for tunnel segment reinforcement cages suffer from limitations in dimensional adaptability and uneven load-bearing capacity. Specifically, traditional storage racks utilize welded, fixed frame structures with fixed parameters such as the spacing, curvature, and height of the supporting beams. This makes them inflexible in adapting to tunnel segment reinforcement cages of varying diameters, curvatures, and lengths. This necessitates custom-made storage racks for different cage specifications, increasing equipment investment costs. Furthermore, as curved, thin-walled spacer structures, the reinforcement cages, when directly stacked, have fewer contact points with the rack at the bottom layer, making them prone to plastic deformation due to localized stress concentration, such as surface collapse or radial twisting. These problems not only affect the finished quality of the reinforcement cages but also reduce the product yield.
[0033] To address the aforementioned technical problems, this embodiment provides a storage and inspection table for tunnel segment reinforcement cages. (See reference...) Figure 1 and Figure 2 As shown, Figure 1 This is a perspective view of the inspection table for storing the steel reinforcement cage of the tunnel lining segments in an embodiment of this application. Figure 2 yes Figure 1 A schematic diagram of region A in the middle.
[0034] The segment reinforcement cage storage and inspection platform of this embodiment includes: a support plate 1 and several adjustment components 2 located at the lower end of the support plate 1.
[0035] The support plate 1 has elastic bending capability and is evenly distributed with a number of bolt holes 11. Even distribution means that the bolt holes 11 are evenly distributed in the length and width directions of the support plate 1.
[0036] The adjustment assembly 2 is used to set the support plate 1 on the ground according to a preset arc. It includes a base 21, a screw 22, a locking nut 23, and a support nut 24. The base 21 is fixedly installed on the ground by ground bolts and is fixedly provided with a screw sleeve 211. One end of the screw 22 extends into a bolt hole 11 of the support plate 1, and the other end is movably inserted into the screw sleeve 211. The locking nut 23 is connected to the screw 22 and fixes the screw 22 in the bolt hole 11 of the support plate 1. The support nut 24 is connected to the screw 22 and is supported on the upper end of the screw sleeve 211. It is configured to adjust the height of the support plate 1.
[0037] Several adjusting components 2 are connected to bolt holes 11 at different positions on the support plate 1 via their respective screws 22, so as to adjust the curvature of the support plate 1 to match the curvature of the steel cage 3. It can be understood that the adjusting components 2 at different positions force the support plate 1 to bend by adjusting the height of the support plate 1 at different positions, thereby adapting its curvature to the curvature of the steel cage 3.
[0038] It is understandable that the length and angle of the screws 22 of each of the above-mentioned adjustment components 2 are adapted to the preset height and curvature of the support plate 1, and they can be the same or different from each other.
[0039] In some embodiments of the adjusting assembly 2, the adjusting assembly 2 includes a central adjusting assembly 25 and at least two sets of side adjusting assemblies 26; the screw 22 of the central adjusting assembly 25 is connected to the bolt hole 11 in the middle of the support plate 1; the side adjusting assemblies 26 are symmetrically distributed around the central adjusting assembly 25 and are connected to the bolt holes 11 at both ends of the support plate 1 through their respective screws 22. In this way, the central adjusting assembly 25 and the side adjusting assemblies 26 work together to more stably support and adjust the height, curvature, and arc of the support plate 1, resulting in a more stable overall structure.
[0040] Furthermore, the screw 22 and screw sleeve 211 of the central adjustment component 25 are vertically arranged; the screw 22 and screw sleeve 211 of the side adjustment component 26 are inclined relative to the vertical direction. This arrangement allows the inclined screw 22 to conform to the curvature of the support plate 1, resulting in a tighter connection between them. It also helps generate lateral support force when adjusting the height of the support plate 1, preventing it from tipping over or swaying when supporting the reinforcing cage 3. The inclination angle can be adjusted according to actual needs and the dimensions of the support plate 1.
[0041] In some implementations, a longer screw 22 is therefore required to provide sufficient stability and load-bearing capacity. The side adjustment assembly 26 mainly serves as an auxiliary support and angle adjustment component, so the length of the screw 22 can be relatively short, i.e., the length of the screw 22 of the central adjustment assembly 25 is greater than the length of the screw 22 of the side adjustment assembly 26.
[0042] In some embodiments, a buffer pad 27 is provided between the locking nut 23 and the support plate 1. The buffer pad 27 can be made of rubber, foam, or other elastic materials, and its function is to reduce the direct pressure of the locking nut 23 on the support plate 1, preventing the support plate 1 from deforming or being damaged due to prolonged pressure. At the same time, the buffer pad 27 can also provide a certain degree of shock absorption, reducing the noise and vibration generated during the storage and inspection of the reinforcing cage 3.
[0043] Furthermore, the buffer pad 27 is provided with a sleeve hole 271, and is sleeved on the upper end of the screw 22 through the sleeve hole 271.
[0044] In some embodiments, the base 21 includes a base plate 212 and at least three stiffening plates 213 evenly distributed around the periphery of the screw sleeve 211; the two ends of the stiffening plates 213 are welded to the base plate 212 and the screw sleeve 211, respectively. The two ends of the stiffening plates 213 are welded to the base plate 212 and the screw sleeve 211, respectively, forming a robust support structure. This design increases the load-bearing capacity and stability of the base 21, preventing overturning or deformation during storage and inspection of the reinforcing cage 3. Furthermore, the number and distribution of the stiffening plates 213 can be adjusted according to actual needs to meet the storage requirements of reinforcing cages 3 of different sizes and weights.
[0045] It is understood that the aforementioned support plate 1 can be a steel plate with elastic deformation capability, and there can be one or more of them. When there are multiple support plates, each support plate 1 together supports the reinforcing cage 3.
[0046] The installation process of the inspection table for the rebar cage storage is as follows: First, install the base 21 and place it stably in the predetermined position. If the base 21 needs to be fixed, expansion bolts or other suitable fixing devices can be used to firmly install the base 21 on the ground. Then, install the adjustment component 2, passing the screw 22 through the screw sleeve 211 on the base 21. Then, install the support nut 24 at the appropriate position on the screw 22, ensuring that the support nut 24 can rotate freely up and down without falling off. Install the locking nut 23 on the top of the screw 22 for subsequent fixing of the height of the support plate 1. Finally, install the support plate 1: place the support plate 1 above the adjustment component 2, ensuring that the bolt holes 11 on the support plate 1 are aligned with the screw 22. Connect the support plate 1 to the screw 22 by selecting the appropriate bolt holes 11. As needed, the height, curvature, and arc of the support plate 1 can be adjusted using the locking nut 23 or the support nut 24 to accommodate different specifications of rebar cages 3. After confirming the position and height of the support plate 1, use tools to tighten the locking nut 23 to ensure that the support plate 1 is stable and immovable.
[0047] The support plate 1 of the segment reinforcement cage storage and inspection table of this application has elastic bending capability and is evenly distributed with a number of bolt holes 11. It allows multiple adjustment components 2 to be connected through different bolt holes 11, thereby adjusting the height, bending degree, and curvature of the support plate 1 to adapt to reinforcement cages 3 of different specifications, improving the applicability to reinforcement cages 3 of various sizes. At the same time, compared with traditional storage racks, the curvature-adaptive support plate 1 can increase the contact surface with the reinforcement cage 3, providing more comprehensive and uniform support for the reinforcement cage 3, improving the uniformity of load bearing. This helps to disperse the stress generated when the reinforcement cages 3 are stacked, reducing the plastic deformation of the bottom reinforcement cage 3 due to local stress concentration. Equally important, the adjustment component 2 includes a base 21, a screw 22, a locking nut 23, and a support nut 24, so that the height of the support plate 1 can be flexibly adjusted by the screw 22 and the support nut 24. By adjusting the height, the vertical space can be maximized, increasing the storage capacity per unit area and improving the space utilization rate.
[0048] It is understood that the segment reinforcement cage storage and inspection table of this application can be used to store reinforcement cages and can also be used as a testing table for reinforcement cages to carry out testing operations in conjunction with testing equipment.
[0049] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
