Description

Technical Field

[0001] This utility model relates to the field of concrete embedded parts technology, specifically to an inverted U-shaped serrated reinforced embedded part with concave and convex surfaces. Background Technology

[0002] In the field of building construction, embedded parts are key components connecting different structural parts, and their performance directly determines the quality and safety of the entire project. However, existing embedded parts have revealed many defects in practical applications.

[0003] Some embedded parts have insufficient structural strength. In complex construction environments, they are prone to structural damage due to localized stress concentration under significant external forces, thus affecting overall stability and compromising long-term project safety. For example, the concrete embedded parts for civil construction disclosed in Chinese Patent Publication No. CN216766272U, while showing some improvement, still have shortcomings in handling complex stress conditions. The connection between some embedded parts and the concrete substrate is not secure enough, making them prone to loosening or even pull-out under vibration or tensile forces, failing to meet long-term usage requirements. Furthermore, some embedded parts use multi-component connection methods, resulting in connection defects such as weld seams and bolt gaps. This not only leads to uneven stress distribution, reducing overall strength and fatigue resistance, but also results in complex manufacturing processes, low production efficiency, and poor product consistency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an inverted U-shaped concave-convex surface sawtooth reinforced embedded part.

[0005] The technical solution adopted in this utility model is as follows: A U-shaped serrated reinforced embedded part with an inverted U-shape includes a U-shaped body, which includes a lifting section and symmetrically arranged support legs below the lifting section. The lifting section has a lifting hole in the middle for lifting. The outer side of the support legs protrudes forward to form a reinforcing edge, and the inner side of the support legs has a serrated edge. A reinforcing rib that protrudes forward perpendicularly to the support legs is provided between the serrated edge and the reinforcing edge. The reinforcing edge and the reinforcing rib are vertically connected to form a stepped concave-convex surface. The end of the support legs is provided with an inwardly bent barb.

[0006] This technical solution achieves high strength and stable connection of embedded parts through an inverted U-shaped design, a combination of reinforcing edges and ribs, serrated edges, and barbs, thus better adapting to complex construction environments and improving construction efficiency and safety. Specifically, the inverted U-shaped design, along with the rational layout of the lifting section and outriggers, achieves force distribution and concentration; the lifting holes facilitate lifting operations; the combination of reinforcing edges and ribs enhances structural strength; the serrated edges increase friction or are used for specific connections; and the barbs ensure a stable connection between the embedded parts and concrete. The overall structure optimizes material usage while ensuring strength, improving construction efficiency and safety.

[0007] In addition, the inverted U-shaped serrated reinforced embedded part with concave and convex surfaces proposed in this utility model may also have the following additional technical features: According to one embodiment of the present invention, the number of reinforcing ribs is at least three, which are evenly distributed on the serrated edge extension direction on the front of the leg.

[0008] In this technical solution, at least three reinforcing ribs can form multiple lines of support; when the embedded part is subjected to external force, the reinforcing ribs can effectively disperse the stress, avoid local stress concentration leading to structural damage, and enhance the overall resistance to damage; the uniform distribution ensures that the outrigger is subjected to uniform force in all parts, and will not cause uneven force due to sparse or dense local reinforcing ribs, thus maintaining structural stability; reinforcing ribs are set in the extension direction of the serrated edge, and the reinforcing ribs specifically strengthen the serrated edge, improving its resistance to deformation and tearing.

[0009] According to one embodiment of the present invention, the width of the reinforcing rib is greater than the width of the reinforcing edge, and the height of the reinforcing rib is the same as the height of the reinforcing edge.

[0010] In this technical solution, the reinforcing ribs are wider, and the larger contact area can more effectively disperse stress, distributing concentrated force to a wider area and reducing the risk of structural damage caused by local stress concentration. The same height allows the reinforcing ribs and reinforcing edges to bear the force simultaneously when subjected to vertical forces, avoiding uneven stress caused by height differences, which could lead to structural deformation or damage.

[0011] According to one embodiment of the present invention, the bending angle of the barb is 30°-60°, and the length of the barb is 1 / 5-1 / 3 of the length of the support leg.

[0012] In this technical solution, the bending angle range ensures that the barb is smoothly embedded in the concrete while also generating sufficient resistance to effectively prevent the embedded part from loosening or being pulled out. The length range ensures sufficient anchoring force while also considering material costs and ease of construction, allowing the embedded part to be firmly connected to the concrete.

[0013] According to one embodiment of the present invention, the legs form an arch with a certain angle between them, and the angle of the arch ranges from 10° to 30°.

[0014] In this technical solution, the arched structure in concrete can better fit with the substrate, increase the contact area, and improve the anchoring force.

[0015] According to one embodiment of the present invention, the hoisting part and the outrigger part are integrally formed.

[0016] In this technical solution, the integral molding avoids the connection defects that may exist in traditional multi-part connections, such as weld seams at welding points and gaps at bolt connections; stress can be evenly distributed throughout the entire structure, greatly improving the overall strength and fatigue resistance of the embedded parts.

[0017] Compared with the prior art, this utility model has the following advantages: The outriggers of this invention feature an arched shape of 10°-30° with multiple reinforcing ribs, which can distribute the force, enhance the overall stability and anchoring performance, and effectively prevent loosening and displacement; the stepped concave-convex surface and the barbs of a specific size greatly increase the contact area and friction with the concrete.

[0020] 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.

[0021] Example 1 like Figure 1 As shown, this embodiment provides an inverted U-shaped serrated reinforced embedded part, including a U-shaped body 1 arranged in an inverted U shape. The U-shaped body 1 includes a lifting part and support legs symmetrically arranged below the lifting part. The lifting part has a lifting hole 2 for lifting in the middle. The outer side of the support leg protrudes forward to form a reinforcing edge 3, and the inner side of the support leg is a serrated edge. A reinforcing rib 4 that protrudes forward perpendicularly to the support leg is provided between the serrated edge and the reinforcing edge 3. The reinforcing edge 3 and the reinforcing rib 4 are vertically connected to form a stepped concave-convex surface. The end of the support leg is provided with an inwardly bent barb 5.

[0022] This technical solution achieves high strength and stable connection of the embedded parts through an inverted U-shaped design, a combination of reinforcing edges 3 and 4, and the use of serrated edges and barbs 5. This makes it more adaptable to complex construction environments and improves construction efficiency and safety. Specifically, the inverted U-shaped design, along with the rational layout of the lifting section and outriggers, achieves force distribution and concentration; the lifting hole 2 facilitates lifting operations; the combination of reinforcing edges 3 and 4 enhances structural strength; the serrated edges increase friction or are used for specific connections; and the barbs 5 ensure a stable connection between the embedded parts and concrete. The overall structure optimizes material usage while ensuring strength, thus improving construction efficiency and safety.

[0023] In addition, the inverted U-shaped serrated reinforced embedded part with concave and convex surfaces proposed in this utility model may also have the following additional technical features: According to one embodiment of the present invention, the number of reinforcing ribs 4 is at least three, which are evenly distributed on the serrated edge extension direction on the front of the leg.

[0024] In this technical solution, at least three reinforcing ribs 4 can form multiple support lines; when the embedded part is subjected to external force, the reinforcing ribs 4 can effectively disperse the stress, avoid local stress concentration leading to structural damage, and enhance the overall resistance to damage; the uniform distribution ensures that the support leg is subjected to uniform force in all parts, and there will be no uneven force due to the sparse or dense local reinforcing ribs 4, thus maintaining structural stability; reinforcing ribs 4 are set in the extension direction of the serrated edge, and the reinforcing ribs 4 specifically strengthen the serrated edge, improving its resistance to deformation and tearing.

[0025] According to one embodiment of the present invention, the width of the reinforcing rib 4 is greater than the width of the reinforcing edge 3, and the height of the reinforcing rib 4 is the same as the height of the reinforcing edge 3.

[0026] In this technical solution, the reinforcing rib 4 is wider, and the larger contact area can more effectively disperse stress, distributing the concentrated force to a wider area and reducing the risk of structural damage caused by local stress concentration. The same height allows the reinforcing rib 4 and the reinforcing edge 3 to bear the vertical force simultaneously, avoiding uneven force due to height differences, which could lead to structural deformation or damage.

[0027] According to one embodiment of the present invention, the bending angle of the barb 5 is 30°-60°, and the length of the barb 5 is 1 / 5-1 / 3 of the length of the support leg.

[0028] In this technical solution, the bending angle range ensures that the barb 5 is smoothly embedded in the concrete while also generating sufficient resistance to effectively prevent the embedded part from loosening or being pulled out. The length range ensures sufficient anchoring force while taking into account material costs and ease of construction, ensuring a firm connection between the embedded part and the concrete.

[0029] According to one embodiment of the present invention, the legs form an arch with a certain angle between them, and the angle of the arch ranges from 10° to 30°.

[0030] In this technical solution, the arched structure in concrete can better fit with the substrate, increase the contact area, and improve the anchoring force.

[0031] According to one embodiment of the present invention, the hoisting part and the outrigger part are integrally formed.

[0032] In this technical solution, the integral molding avoids the connection defects that may exist in traditional multi-part connections, such as weld seams at welding points and gaps at bolt connections; stress can be evenly distributed throughout the entire structure, greatly improving the overall strength and fatigue resistance of the embedded parts.

[0033] The usage process of the above embodiments is as follows: Figure 1 As shown, the embedded parts are precisely placed at the concrete pouring position; the outriggers are U-shaped with a certain arched angle, which can distribute the force and enhance the overall stability; the outer reinforcing edge 3, the inner serrated edge, and the reinforcing ribs 4 between the outriggers form a stepped concave-convex surface, which greatly increases the contact area and friction with the concrete; at least three evenly distributed reinforcing ribs 4, with a width greater than the reinforcing edge 3 and the same height, further strengthen the structure and improve the anchoring performance; the barb 5 at the end of the outriggers, with a bending angle of 30°-60° and a length of 1 / 5-1 / 3 of the outrigger length, firmly "grips" the concrete like an anchor after the concrete is poured, preventing the embedded parts from loosening and shifting. The hoisting part and the outriggers are integrally processed and formed, ensuring the integrity of the structure; after the concrete solidifies, the embedded parts are firmly embedded in it, and can be reliably connected to other structural components to meet the connection and fixing requirements of building engineering.

[0034] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, it is not limited thereto. Various equivalent modifications or substitutions can be made to the embodiments of the present invention by those skilled in the art without departing from the spirit and essence of the present invention, and such modifications or substitutions should all be within the scope of the present invention.

Therefore, the protection scope of the present invention should be determined by the scope of the claims.
