Description

Technical Field

[0001] This utility model relates to the field of foundation pit support technology in building engineering, and specifically to a weld-free steel support hanging plate. Background Technology

[0002] In deep foundation pit engineering, steel supports need to be fixed to steel walers using hanging plates. The traditional fixing method is on-site welding, which suffers from low efficiency, high safety risks, and non-reusable components. To overcome these shortcomings, existing technologies have proposed various improvement schemes. After review and analysis, the relevant improvements mainly fall into the following categories:

[0003] For example, the technical solutions disclosed in Chinese utility model patents with announcement numbers CN208430517U and CN211898411U use complex mechanical structures such as rotating shafts, clamping plates, and electric telescopic rods to achieve the snap-fit ​​connection with the waler. Although these solutions achieve welding-free operation, they are complex in structure, have many parts, and high manufacturing costs. Moreover, they rely on electricity or precision adjustment on site, and their reliability is greatly affected by the environment and operation, making maintenance inconvenient.

[0004] For example, the technical solutions disclosed in Chinese utility model patents with announcement numbers CN210263076U and CN219568961U use a large number of bolts (such as main bolts, auxiliary bolts, expansion bolts, etc.) to fix the hanging plate to the waler or crown beam. Although this type of solution avoids welding, the installation process requires drilling, aligning the holes, and tightening multiple bolts one by one, which is cumbersome, time-consuming, and causes drilling damage to the waler, thus reducing its reusability.

[0005] For example, the technical solution disclosed in Chinese utility model patent CN210421108U is a Z-shaped plate that is welded as a whole and fixed by pre-embedded ribs or bolts; its essence still requires secondary connection with the structure (welding or bolting), and it is not an independent weld-free hanging unit. Moreover, the structure is bulky and the amount of steel used is uneconomical.

[0006] In summary, existing weld-free or detachable panel solutions generally suffer from problems such as complex structures, slow installation, damage to walers, or high steel consumption, failing to achieve a balance between "extremely simple structure, extremely fast installation, non-destructive disassembly and assembly, and economical material usage." Therefore, a more optimized integrated weld-free panel solution is still needed. Utility Model Content

[0007] The purpose of this utility model is to provide a weld-free steel support panel to solve the technical problems of existing weld-free or detachable panel solutions, which generally have complex structures, are not quick to install, damage to the walers, or have a large amount of steel consumption.

[0017] Furthermore, the supporting and limiting assembly includes a horizontal supporting plate, a lateral limiting plate, and a vertical supporting plate;

[0018] The horizontal support plate is welded to the second mounting side to provide support for the steel support;

[0019] The lateral limiting plate is located at the upper end of the horizontal support plate and is connected to both the horizontal support plate and the vertical connecting plate. The lateral limiting plate is used to limit the horizontal movement of the steel support.

Detailed Implementation

[0033] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, the weld-free steel support hanging plate provided in this embodiment mainly includes a vertical connecting plate 1, an irregular hook hanging plate 2, and a support and limiting component 3.

[0036] The vertical connecting plate 1 serves as the main load-bearing structure of the hanging plate, and its two sides are functionally divided into a first installation side and a second installation side. The first installation side faces the steel waler 4 and is used to achieve assembly connection with the steel waler 4; the second installation side faces the steel support 5 and is used to support and fix the steel support 5. Through this partitioned design, the force transmission path of the hanging plate is clearly defined in its structure, which facilitates rapid on-site alignment and installation.

[0037] In the actual installation process, in order to achieve a quick and non-destructive connection between the hanging plate and the steel waler 4, a special-shaped hook hanging plate 2 is connected to the upper part of the first installation side.

[0038] The irregularly shaped hook plate 2 has a downward-facing hook portion 21, which can be directly hooked onto the upper flange 41 of the steel waler 4 during installation. This hooking method eliminates the need for welding on the waler, which not only protects the integrity of the waler but also greatly improves installation efficiency, while creating conditions for subsequent dismantling and reuse.

[0039] Considering the reliability of the hook structure under stress, the bent hook part 21 can be formed by cutting a trapezoidal cut on the irregular hook plate 2. This shape ensures the hook depth while facilitating stress dispersion and avoiding deformation or damage caused by local stress concentration.

[0040] In addition, the hook part 21 can also be formed by cold bending or welding of arc-shaped plate segments. As long as a reliable downward hooking function is achieved, it can be included in the protection scope of this solution.

[0041] To further improve the connection strength between the irregular hook plate 2 and the vertical connecting plate 1, especially when bearing a large support load, reinforcing welding plates 22 can be welded between the two sides of the irregular hook plate 2 and the vertical connecting plate 1.

[0042] The reinforcing plate 22 can be a rectangular plate, which can effectively increase the bending and shear resistance of the node after welding, and prevent the weld from cracking due to repeated disassembly or load impact.

[0043] In addition, the irregular hook plate 2 can be arranged in two according to the width of the steel support 5. For example, in application, the irregular hook plate 2 can be set on the upper two sides of the steel waler 4 to form a symmetrical force system and improve the overall stability and load balance of the hanging plate.

[0044] Although the irregular hook plate 2 can achieve the main suspension function, in actual foundation pit engineering, the steel waler 4 may vibrate or slightly displace due to external loads. In order to avoid the hanging plate from accidentally coming off the hook, this solution sets auxiliary connection holes 11 on the vertical connecting plate 1.

[0045] The auxiliary connection hole 11 can be used to install the auxiliary anti-slip component 12, such as an anti-slip pin. During installation, the auxiliary anti-slip component 12 passes through the auxiliary connection hole 11 and abuts against the web plate 42 of the steel waler 4, forming a lateral constraint, thereby preventing the hanging plate from accidentally slipping off along the waler flange direction.

[0046] At least two auxiliary connection holes 11 can be provided and distributed on the circumference of the steel support 5 to form multi-point tightening and enhance the anti-loosening effect. In addition to the anti-loosening pin, the auxiliary anti-loosening component 12 can also adopt adjustable components such as wedge blocks and tightening screws to adapt to the tightening requirements of web plates 42 with different thicknesses.

[0047] Considering that the hanging plate in the foundation pit support system needs to be connected with the retaining piles to enhance the overall stability, this scheme can also provide an auxiliary tie hole 13 through the upper part of the vertical connecting plate 1. The center of the auxiliary tie hole 13 should be located on the center line of the vertical connecting plate 1 to facilitate connection with external tie components (such as steel wire ropes, steel bar tie rods, etc.), thereby achieving reliable connection with the retaining piles. This design not only enhances the overturning resistance of the hanging plate, but also makes the support system form an overall coordinated force.

[0048] A support and limiting assembly 3 is connected to the lower part of the second mounting side of the mounting plate. This assembly is mainly used to support the steel support 5 and limit its horizontal movement. Specifically, the support and limiting assembly 3 includes a horizontal support plate 31, a lateral limiting plate 32, and a vertical support plate 33.

[0049] The horizontal support plate 31 is welded to the vertical connecting plate 1 to provide a bottom support surface for the steel support 5; the lateral limiting plate 32 is located at the upper end of the horizontal support plate 31 and is connected to the horizontal support plate 31 and the vertical connecting plate 1 to constrain the horizontal movement of the steel support 5; the vertical support plate 33 is located at the lower end of the horizontal support plate 31 and plays a role in enhancing the vertical stiffness of the support structure.

[0050] To further improve the support stability, two vertical support plates 33 can be set up and symmetrically arranged below the horizontal support plate 31.

[0051] Preferably, the lateral limiting plate 32 and the vertical support plate 33 are triangular plates. The triangular structure can save materials and reduce weight while ensuring sufficient support strength.

[0052] In addition, the supporting and limiting component 3 can also be designed as an integrally stamped U-shaped groove structure or an assembled adjustable bracket. As long as it achieves the dual functions of support and limiting, it can be regarded as an equivalent implementation of this utility model.

[0053] The weld-free steel support hanging plate provided in this embodiment achieves rapid suspension through irregular hooks, and enhances safety with anti-detachment and tie-down measures. It also reliably supports the steel support 5 through a specially designed support and limiting component 3, forming a simple, easy-to-install, non-damaging, and reusable foundation pit support hanging system.

[0054] Reference Figure 3 During construction and installation, the operator lifts the weld-free steel support plate, so that the hook part 21 of the irregular hook plate 2 hooks onto the upper flange 41 of the steel waler 4 from top to bottom or from the side, ensuring that the inner top surface 23 of the hook part 21 is in contact with the surface of the upper flange 41. Then, the anti-detachment pin is inserted into the auxiliary connection hole 11 of the vertical connecting plate 1, so that its end is pressed against the web plate 42 of the waler to prevent the entire support plate from sliding longitudinally.

[0055] Finally, the steel support 5 is hoisted and placed stably on the two left and right supporting and limiting components 3, thus completing the installation. Dismantling is performed in reverse order, allowing all components to be recovered without damage.

[0056] Compared with the prior art, the weld-free steel support plate provided in this embodiment has at least the following advantages:

[0057] 1. Compared with existing mounting plates with complex mechanical components such as movable shafts and electric push rods (such as CN208430517U), this solution adopts a fixed structure welded from pure steel plates, with no moving or easily damaged parts, resulting in a robust structure, low failure rate, and good durability.

[0058] 2. Compared to bolt-connected mounting plates (such as CN210263076U) which require multiple drilling and fastening steps, this solution only requires a simple action of "hanging (hanging the hook part onto the waler flange), clamping (optional pin or bolt assistance), and placing (placing the steel support)" during installation. A single person can complete the process in a few seconds, greatly improving assembly efficiency.

[0059] 3. The hook-and-hook connection method of this solution effectively replaces the traditional welding method on the walers, and the walers remain intact after removal, effectively reducing damage to the main structure and laying the foundation for the reuse of components.

[0060] 4. Compared with traditional Z-shaped panels and other large-panel structures (such as CN210421108U), this solution adopts the "hook-and-load transmission + two-point support" method, which makes the structural stress clear, eliminates redundant materials, and makes the components lighter and saves steel under the same load-bearing capacity.

[0061] 5. By changing the cutting size of the irregular hook plate and the position of the supporting components, a series of standard products that can adapt to different waler specifications and different steel support diameters and angles can be quickly derived, which facilitates factory prefabrication and inventory management.

[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
