Description

Technical Field

[0001] This utility model relates to the field of concrete embedded parts technology, specifically to an inverted U-shaped concrete embedded part with a limiting structure. Background Technology

[0002] In the concrete pouring stage of building construction, existing concrete embedded parts have many problems in terms of connection stability and installation accuracy, which seriously affect project quality and construction efficiency. To solve these technical problems, those skilled in the art have conducted numerous explorations. For example, Chinese Patent Publication No. CN215802312U discloses a concrete embedded part for civil engineering construction, which, while showing some improvement, still has shortcomings. Some embedded parts lack effective limiting structures, making it impossible to tightly fit with reinforcing bars and other structures during concrete pouring, thus making it difficult to prevent displacement and causing positional deviations in subsequent structural component connections, reducing overall project quality. Some embedded parts are not designed to save materials and distribute pressure, making them prone to damage due to stress concentration when subjected to concrete pressure, increasing construction costs and safety risks. Other embedded parts have a small contact area with concrete, weak friction, and unstable connections, making them easily pulled out by external forces. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a U-shaped concrete embedded part with a limiting structure.

[0004] The technical solution adopted in this utility model is as follows: A U-shaped concrete embedded part with a limiting structure includes a U-shaped body arranged in an inverted U-shape, with two vertically arranged lifting holes at the top of the U-shaped body; an inwardly recessed notch on the side of the U-shaped body to form a limiting hole; an arched opening in the middle of the U-shaped body, with limiting legs formed on both sides, serrations of different sizes formed on the inner side of the limiting legs, and barbs at the bottom of the limiting legs.

[0005] In this technical solution, the inverted U-shaped structure ensures more even stress distribution on the embedded part within the concrete, better dispersing the pressure exerted by the concrete. The top lifting hole facilitates hoisting and installation during construction. The side limiting holes, in conjunction with the reinforcing steel in the concrete, enhance the anchoring effect and prevent displacement. The central arched opening saves material and further disperses pressure. The serrated section on the inner side of the limiting leg increases the contact area and friction with the concrete, improving connection stability. The bottom barb acts like an anchor hook after the concrete has hardened, firmly gripping the embedded part and preventing it from being pulled out, ensuring a secure bond between the embedded part and the concrete.

[0006] In addition, the inverted U-shaped concrete embedded part with limiting structure proposed above according to this utility model may also have the following additional technical features: According to one embodiment of the present invention, the limiting holes are regularly arranged along the side of the U-shaped body, and the shape of the limiting holes is one of rectangle, trapezoid or irregular polygon.

[0007] In this technical solution, the rectangular limiting hole has a regular structure, is relatively easy to process, and can form a relatively regular fit with components such as reinforcing bars in the concrete, effectively limiting the displacement of embedded parts. The trapezoidal limiting hole is narrower at the top and wider at the bottom, which produces a better self-locking effect as the concrete solidifies and shrinks during the concrete pouring process, further preventing the embedded parts from loosening.

[0008] According to one embodiment of the present invention, the arc of the arched opening is in the range of 60°-180°, and the center of the arched opening is located on the center line of the U-shaped body.

[0009] In this technical solution, when concrete applies pressure to the embedded parts, the arch structure can convert the vertically downward pressure into a component force along the arch surface, so that the pressure is evenly transmitted to the limiting legs on both sides of the U-shaped body.

[0010] According to one embodiment of the present invention, the serrated part is composed of a plurality of serrations, the shape of which is one of triangle, trapezoid or wave.

[0011] In this technical solution, when the embedded part is pulled by an external force, a large resistance will be generated between the triangular saw teeth and the concrete. This resistance can effectively prevent the embedded part from being pulled out of the concrete, greatly enhancing the stability of the connection. The lateral pressure of the concrete on the trapezoidal saw teeth will make it more tightly bonded to the embedded part, further improving the anchoring force between the embedded part and the concrete, preventing loosening and displacement.

[0012] According to one embodiment of the present invention, the barb portion is bent toward the inner side of the limiting leg, and the bending angle is 30°-90°.

[0013] In this technical solution, the bending angle is within this range, which enables the barb to form a good mechanical engagement with the concrete. If the angle is less than 30°, the depth and angle of the barb embedded in the concrete are insufficient, and it is easy for the embedded part to come out of the concrete when it is subjected to tensile force, which cannot effectively prevent the embedded part from being pulled out. If the angle is greater than 90°, the barb may hinder the full filling of the concrete during the concrete pouring process, resulting in gaps around the barb and reducing the anchoring effect.

[0014] According to one embodiment of the present invention, a limiting plate is welded to the side of the U-shaped body and is arranged perpendicularly thereto. The limiting plate is rectangular.

[0015] In this technical solution, when the concrete applies lateral compression or tension to the U-shaped body, the limiting plate acts as a sturdy "baffle," distributing some of the force to the surrounding concrete and preventing the U-shaped body from deforming or shifting due to excessive local stress.

[0016] Compared with the prior art, this utility model has the following advantages: The limiting hole on the side of this utility model cooperates with the steel reinforcement in the concrete. The serrated part on the inner side of the limiting leg increases the contact area and friction with the concrete. The bottom barb part acts like an anchor hook to firmly grip the concrete. A rectangular limiting plate is added to the side. The multi-structure synergy enhances the anchoring of the embedded part with the concrete, preventing displacement and pull-out.

[0019] 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.

[0020] Example 1 like Figure 1 As shown, this embodiment provides a U-shaped concrete embedded part with a limiting structure, including a U-shaped body 1 arranged in an inverted U-shape, with two vertically arranged lifting holes 2 on the top of the U-shaped body 1; the side of the U-shaped body 1 is provided with an inwardly recessed notch to form a limiting hole 3; the middle of the U-shaped body 1 is an arched opening 4, and limiting legs are formed on both sides, with serrated parts 5 of different sizes formed on the inner side of the limiting legs, and a barb part 6 is provided at the bottom of the limiting legs.

[0021] In this technical solution, the inverted U-shaped structure ensures more even stress distribution on the embedded part within the concrete, better dispersing the pressure exerted by the concrete. The top lifting hole 2 facilitates hoisting and installation during construction. The side limiting hole 3 engages with the reinforcing steel in the concrete, enhancing anchoring and preventing displacement. The central arched opening 4 saves material and further disperses pressure. The serrated portion 5 on the inner side of the limiting leg increases the contact area and friction with the concrete, improving connection stability. The bottom barb 6, after the concrete has hardened, acts like an anchor hook, firmly gripping the concrete and preventing the embedded part from being pulled out, ensuring a secure bond between the embedded part and the concrete.

[0022] In addition, the inverted U-shaped concrete embedded part with limiting structure proposed above according to this utility model may also have the following additional technical features: According to one embodiment of the present invention, the limiting holes are regularly arranged along the side of the U-shaped body 1, and the shape of the limiting holes 3 is one of rectangle, trapezoid or irregular polygon.

[0023] In this technical solution, the rectangular limiting hole 3 has a regular structure and is relatively easy to process. It can form a relatively regular fit with components such as steel bars in the concrete, and is highly effective in limiting the displacement of embedded parts. The trapezoidal limiting hole 3 is narrower at the top and wider at the bottom. During the concrete pouring process, as the concrete solidifies and shrinks, it can produce a better self-locking effect, further preventing the embedded parts from loosening.

[0024] According to one embodiment of the present invention, the arc of the arched opening 4 is in the range of 60°-180°, and the center of the arched opening 4 is located on the center line of the U-shaped body 1.

[0025] In this technical solution, when concrete applies pressure to the embedded parts, the arch structure can convert the vertically downward pressure into a component force along the arch surface, so that the pressure is evenly transmitted to the two limiting legs of the U-shaped body 1.

[0026] According to one embodiment of the present invention, the sawtooth part 5 is composed of a plurality of sawtooths, the shape of which is one of triangle, trapezoid or wave.

[0027] In this technical solution, when the embedded part is pulled by an external force, a large resistance will be generated between the triangular saw teeth and the concrete. This resistance can effectively prevent the embedded part from being pulled out of the concrete, greatly enhancing the stability of the connection. The lateral pressure of the concrete on the trapezoidal saw teeth will make it more tightly bonded to the embedded part, further improving the anchoring force between the embedded part and the concrete, preventing loosening and displacement.

[0028] According to one embodiment of the present invention, the barb portion 6 is bent toward the inner side of the limiting leg, and the bending angle is 30°-90°.

[0029] In this technical solution, the bending angle is within this range, which enables the barb 6 to form a good mechanical engagement with the concrete. If the angle is less than 30°, the depth and angle of the barb 6 embedded in the concrete are insufficient, and it is easy to detach from the concrete when the embedded part is subjected to tensile force, which cannot effectively prevent the embedded part from being pulled out; if the angle is greater than 90°, the barb 6 may hinder the full filling of concrete during the concrete pouring process, resulting in gaps around the barb 6 and reducing the anchoring effect.

[0030] According to one embodiment of the present invention, a limiting plate 7 is welded to the side of the U-shaped body 1 and is arranged perpendicularly thereto. The limiting plate 7 is rectangular.

[0031] In this technical solution, when the concrete applies lateral compression or tension to the U-shaped body 1, the limiting plate 7 acts as a sturdy "baffle" to distribute part of the force to the surrounding concrete, preventing the U-shaped body 1 from deforming or shifting due to excessive local stress.

[0032] The usage process of the above embodiments is as follows: like Figure 1 As shown, during concrete pouring, the regularly arranged limiting holes 3 on the sides of the U-shaped body 1 cooperate with the reinforcing steel and other structures in the concrete to enhance the anchoring effect between the embedded part and the concrete, preventing it from shifting within the concrete. The design of the central arched opening 4 saves materials and disperses the pressure of the concrete on the embedded part; the serrated parts 5 of varying sizes on the inner sides of the limiting legs further increase the contact area and friction with the concrete, improving the connection stability. The barbed parts 6 at the bottom of the limiting legs bend inwards, and after the concrete solidifies, they can firmly "grip" the concrete like an anchor hook, preventing the embedded part from being pulled out; in addition, the rectangular limiting plates 7 welded to the sides of the U-shaped body 1 interact with the concrete, limiting the positional displacement of the embedded part during pouring, ensuring accurate installation, and ultimately making the embedded part firmly bonded to the concrete, meeting the connection and fixing requirements in subsequent projects.

[0033] 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. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the scope of the claims.
