Description

Technical Field

[0001] This utility model belongs to the technical field of steel cage triangular bracing, specifically, it relates to a steel cage triangular bracing with buckles that can resist compression and tension. Background Technology

[0002] In the field of building construction, especially in the construction of various concrete structures, rebar cages play a crucial role. A rebar cage is a steel skeleton formed by welding or binding longitudinal and transverse reinforcing bars. It is placed within the formwork of the poured concrete, providing the concrete structure with strong tensile and bending resistance, thereby ensuring the stability and safety of the building. The rebar cage triangular brace is a key supporting component in the rebar cage structure. Its main function is to provide stable internal support for the rebar cage during fabrication, transportation, and installation, preventing deformation due to its own weight, external compression, or vibration. This ensures that the rebar cage maintains its designed shape and dimensional accuracy throughout all construction stages, thus guaranteeing the quality of the entire concrete structure.

[0003] Traditional steel cage bracing has gradually revealed numerous drawbacks over long-term use. Firstly, regarding structural stability, many traditional bracing systems employ simple triangular frame structures lacking effective reinforcement measures. This type of structure is prone to deformation or even damage when subjected to significant pressure and tension. For example, in some large-scale construction projects, due to the complex environment of the construction site and the substantial weight of the steel cage itself, traditional bracing struggles to withstand various stresses during construction, leading to localized deformation of the steel cage and severely impacting its overall quality and the effectiveness of subsequent concrete pouring. Secondly, in terms of fixing methods, traditional steel cage bracing typically uses simple binding or welding to secure it to the steel cage. Binding is not only cumbersome but also ineffective, easily leading to loosening during construction and failing to ensure the bracing continues to provide continuous and effective support. While welding is relatively robust, disassembly or adjustment of the bracing after the steel cage is fabricated is extremely difficult, and the welding process may affect the material properties of the steel reinforcement, reducing its strength and durability. Furthermore, traditional steel cage bracing has poor versatility. Different specifications of rebar cages require different sizes and structures of triangular bracing, which necessitates the construction unit to prepare a large number of triangular bracing of different specifications before construction, increasing construction costs and management difficulty. Moreover, in actual construction, if a rebar cage of special specifications is encountered, the existing triangular bracing may not be able to meet the support requirements, and temporary modifications or re-fabrication are necessary, which seriously affects the construction progress.

[0008] Based on the above technical solution, the present invention provides a snap-locked, compressive and tensile resistant steel cage triangular brace, which can be further improved as follows:

[0009] The upper and lower card plates are provided with crescent-shaped card slots on their inner sides, and the inner walls of the crescent-shaped card slots are provided with anti-slip textures.

[0011] Furthermore, one end of the connecting pin is provided with a limiting head, and the other end is provided with an elastic retaining spring.

[0012] The beneficial effects of adopting the above-mentioned improvement scheme are: by setting a limit head and an elastic retaining ring, the connecting pin is prevented from falling off, thus improving the reliability of the connection.

[0013] Furthermore, the outer wall of the limiting sleeve is provided with reinforcing ribs, which are evenly distributed radially.

[0014] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting reinforcing ribs, the structural strength of the limiting sleeve is enhanced, and the overall stability is improved.

[0015] Furthermore, the outer wall of the limiting block is provided with an annular groove, and a sealing ring is provided inside the annular groove.

[0016] The beneficial effects of adopting the above-mentioned improvement scheme are: by setting a sealing ring, impurities are prevented from entering the inside of the limiting sleeve, thus extending its service life.

[0017] Furthermore, the outer wall of the adjusting screw is provided with a rust-proof layer, which is made by a galvanizing process.

[0018] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting an anti-rust layer, the corrosion resistance of the adjusting screw is improved, and its service life is extended.

[0019] Furthermore, the elastic washer is made of rubber material with a hardness of 60-70 degrees.

[0020] The beneficial effects of adopting the above-mentioned improvement scheme are: by selecting rubber materials with appropriate hardness, the sealing effect can be guaranteed without deformation due to excessive softness.

[0021] Furthermore, the three steel pipes of the main support frame are all made of Q235 steel, and the wall thickness of the steel pipes is 3-5 mm.

[0022] The beneficial effects of adopting the above-mentioned improvement scheme are: by selecting Q235 steel and a suitable wall thickness, both the strength requirements are guaranteed and the overall weight is controlled.

[0023] Furthermore, the thickness of the reinforcing rib is 8-10 mm, and the weld between the reinforcing rib and the steel pipe is double-sided welded.

[0024] The beneficial effects of adopting the above-mentioned improvement scheme are: by setting an appropriate thickness of the reinforcing rib and using a double-sided welding process, the connection strength is improved.

[0025] Furthermore, the outer wall of the limiting block is provided with a cross-shaped groove, and the inner wall of the limiting sleeve is provided with a guide protrusion that cooperates with the cross-shaped groove.

[0026] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a cross-shaped groove and a guide protrusion, the limit block is prevented from rotating inside the limit sleeve, thereby improving the accuracy of adjustment.

[0027] Compared with existing technologies, the beneficial effects of the snap-fit, compressive and tensile resistant steel cage triangular brace provided by this utility model are:

[0028] Structural Stability and Strength Enhancement: This invention utilizes the stability principle of triangles by setting up a triangular structure for the main support frame, providing stable and strong support force and effectively preventing deformation of the rebar cage during construction. Whether in the fabrication, transportation, or installation of the rebar cage, this stable triangular structure reliably maintains the shape and dimensional accuracy of the cage. Simultaneously, reinforcing ribs are installed at the ends of the main support frame, greatly enhancing structural strength. The presence of these reinforcing ribs disperses the stress acting on the main support frame, enabling the entire structure to withstand greater pressure and tension, significantly improving its overall compressive and tensile strength. This is of great significance for ensuring the integrity and stability of the rebar cage in complex construction environments.

[0029] Convenient Fixing Method: The fixing buckle assembly is a major highlight of this invention. Each fixing buckle assembly includes an upper clamping plate, a lower clamping plate, and a connecting pin. The upper and lower clamping plates are hinged together by the connecting pin. This design allows the triangular brace to be quickly fixed to the rebar cage. Compared with traditional binding or welding methods, the operation is more convenient and faster, greatly improving construction efficiency. Furthermore, both the upper and lower clamping plates have crescent-shaped grooves on their inner sides, with anti-slip textures on the inner walls of these grooves. The crescent-shaped grooves increase the contact area with the rebar, making the fixation more secure; the anti-slip textures increase friction, effectively preventing slippage, further ensuring the fixing effect and guaranteeing that the triangular brace remains tightly connected to the rebar cage during construction, stably providing support.

[0030] Flexible Adjustment Function: The combined use of the limiting component and the adjusting component gives this invention the ability to adjust the support position according to actual needs, making it adaptable to different specifications of rebar cages. The limiting component includes a limiting sleeve and a limiting block. The limiting sleeve is fixed in the middle of the three steel pipes of the main support frame, and the limiting block is slidably set inside the limiting sleeve. The adjusting component includes an adjusting screw, an adjusting nut, and an elastic washer. The adjusting screw passes through the limiting block and is threadedly connected to the limiting sleeve. By rotating the adjusting nut, the limiting block can slide within the limiting sleeve, thereby adjusting the support position. This flexible adjustment function greatly improves the versatility of the triangular brace, reduces the cost and management difficulty for construction units to prepare multiple triangular braces for different specifications of rebar cages, and can also better cope with various special situations encountered during construction, ensuring that the construction progress is not affected.

[0047] Specifically, the principle of this utility model is as follows:

[0048] The stability principle of the triangular structure: The main support frame is constructed from three steel pipes of equal length welded into an equilateral triangle, based on the principle of triangle stability. In geometry, a triangle is one of the most stable polygonal structures. When external forces are applied to a triangular structure, its three sides effectively disperse and transfer stress, maintaining the balance and stability of the entire structure. Compared to other polygonal structures, a triangle does not easily change shape when subjected to pressure or tension.

[0049] The principle behind reinforcing ribs enhancing structural strength: Reinforcing ribs are installed at both ends of each steel pipe in the main support frame. This principle is based on stress dispersion and structural reinforcement theories in mechanics. When external forces act on the main support frame, the ends of the steel pipes are areas of stress concentration, making them prone to deformation and damage. The presence of reinforcing ribs increases the cross-sectional area and moment of inertia at the ends, allowing stress to be distributed more evenly over a larger area, thus reducing the stress value per unit area. Simultaneously, the reinforcing ribs and steel pipes form an integral rigid structure, enhancing the bending and shear resistance of the pipe ends, improving the compressive and tensile strength of the entire main support frame, and effectively ensuring the structural integrity of the reinforcing cage under various external forces.

[0050] Working principle of the fixing clip assembly: The fixing clip assembly achieves quick fixation to the rebar cage through the cooperation of the upper clip plate, lower clip plate, and connecting pin. The upper and lower clip plates are hinged together by the connecting pin, forming an openable and closable clamp structure. When it is necessary to fix the triangular brace, the upper and lower clip plates are opened and placed on the rebar of the rebar cage. Then, the upper and lower clip plates are closed by rotating the connecting pin. The crescent-shaped groove on the inside fits tightly with the rebar, increasing the contact area and allowing the fixing force to be evenly distributed on the rebar.

[0051] Working principle of the limiting and adjusting components: The limiting and adjusting components work together to achieve flexible adjustment of the support position. The limiting sleeve is fixed in the middle of the steel pipe of the main support frame, providing a sliding track for the limiting block. The limiting block can slide within the limiting sleeve, and the adjusting screw passes through the limiting block and is threadedly connected to the limiting sleeve. When the adjusting nut is rotated, the adjusting screw will move axially due to the threaded engagement between the nut and the adjusting screw. According to the principle of screw transmission, the rotational motion of the adjusting screw is converted into linear motion, thereby pushing the limiting block to slide within the limiting sleeve. In this way, the position of the limiting block can be precisely adjusted, thereby changing the position of the support point to adapt to the support requirements of different specifications of rebar cages. The elastic washer plays a role in buffering and sealing during the adjustment process, preventing the adjusting nut from loosening and ensuring the stability and reliability of the adjustment.
