Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a concrete embedded part. Background Technology

[0002] Concrete embedded parts refer to components made of metal or other materials that are pre-embedded before or during the pouring of concrete structures. Common types include straight anchor bar embedded parts, hook embedded parts, and anchor plate embedded parts.

[0003] Existing straight anchor bar embedded parts are generally composed of a single steel plate welded with multiple straight anchor bars, used to connect concrete to the external structure. However, the single steel plate has low bending stiffness, and the anchor plate is prone to deformation due to vibration and load during concrete pouring, which can cause the embedded part to shift. The dense arrangement of anchor bars leads to local stress concentration in the concrete, resulting in a high risk of splitting. The load-bearing capacity of a single layer of steel plate is limited, making it difficult to withstand heavy equipment or dynamic loads. Furthermore, the anchor bars are connected only by pull-out force, resulting in weak shear resistance and easy slippage under horizontal loads. Utility Model Content

[0004] The purpose of this utility model is to provide a concrete embedded part to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a concrete embedded part, including an outer anchor plate, a connector installed at the lower end of the outer anchor plate, a composite anchor plate installed at the lower end of the connector, and a plurality of embedded anchor bars installed at the lower end of the composite anchor plate. The lower ends of the plurality of embedded anchor bars are hook-shaped, and the plurality of embedded anchor bars are staggered with each other.

[0006] Preferably, the composite anchor plate includes a first anchor plate and a second anchor plate, and a plurality of reinforcing steel plates are installed between the first anchor plate and the second anchor plate. Side grooves are provided on both sides of the reinforcing steel plates.

[0007] Preferably, the surface of the outer anchor plate has multiple threaded holes.

[0008] Preferably, a plurality of reinforcing anchor bars are installed between the outer anchor plate and the composite anchor plate, located on the outside of the connector.

[0009] Preferably, the spacing between the plurality of reinforcing anchor bars is greater than the spacing between the plurality of pre-embedded anchor bars.

[0010] Preferably, the outer sidewalls of both the first anchor plate and the second anchor plate are equipped with edge serrations.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This concrete embedded part uses an outer anchor plate as the top load-bearing interface and is rigidly connected to the composite anchor plate through connectors, forming a stable frame structure of "double-layer plate + intermediate connection". Compared with traditional single-layer anchor plates, the overall bending stiffness is improved, effectively resisting the lateral pressure during concrete pouring and deformation caused by external loads (such as equipment vibration and wind load), reducing the risk of embedded part displacement or breakage. The multiple embedded anchor bars at the lower end of the composite anchor plate are staggered, avoiding the problem of local stress concentration in concrete caused by the dense arrangement of traditional anchor bars. The ends of the hook-shaped anchor bars form a mechanical interlock with the concrete, and the bonding force of a single anchor bar is improved compared with that of a straight anchor bar. Moreover, the multiple anchor bars distribute the force, reducing the probability of concrete splitting. Through the innovative features of multi-layer composite structure design, staggered hook anchor bar layout and edge serrations, this part systematically solves the problems of insufficient load-bearing capacity, weak deformation resistance, high risk of concrete splitting, and inconvenient installation of traditional straight anchor bar embedded parts. It has significant application value in industrial equipment foundations, high-rise curtain wall keels, and other scenarios.

[0013] 2. This concrete embedded part is fixedly connected to the first anchor plate and the second anchor plate through the middle reinforcing steel plate, forming a multi-layer steel structure composite system. The addition of the reinforcing steel plate significantly improves the compressive strength of the composite anchor plate, which can withstand greater external loads. The side grooves on both sides of the reinforcing steel plate are in direct contact with the concrete, forming a "mechanical lock" effect. When the concrete is poured, the grout can be embedded in the side grooves, increasing the bonding area between the composite anchor plate and the concrete, thereby improving the shear resistance.

[0018] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] like Figures 1 to 3 As shown, the concrete embedded component in this embodiment includes an outer anchor plate 1. A connector 6 is installed at the lower end of the outer anchor plate 1. The connector 6 is an I-shaped plate, which is rigidly connected to the outer anchor plate 1 and the composite anchor plate 2 by bolts, thereby enhancing the overall structural stability. The composite anchor plate 2 is installed at the lower end of the connector 6. Multiple embedded anchor bars 5 are installed at the lower end of the composite anchor plate 2. The lower ends of the multiple embedded anchor bars 5 are hook-shaped. The hook-shaped embedded anchor bars 5 are in direct contact with the concrete. Compared with traditional straight anchor bars, the interlocking force and bonding force between the anchor bars and the concrete are stronger. The multiple embedded anchor bars 5 are staggered, which avoids the problem of local stress concentration in the concrete caused by the dense arrangement of traditional straight anchor bars.

[0021] Specifically, the composite anchor plate 2 includes a first anchor plate 201 and a second anchor plate 202. Multiple reinforcing steel plates 8 are installed between the first anchor plate 201 and the second anchor plate 202. Side grooves 9 are provided on both sides of the reinforcing steel plate 8. The first anchor plate 201 and the second anchor plate 202 are fixedly connected by the intermediate reinforcing steel plate 8 to form a multi-layer steel structure composite system. The addition of the reinforcing steel plate 8 significantly improves the compressive strength of the composite anchor plate 2, which can withstand greater external loads. The side grooves 9 on both sides of the reinforcing steel plate 8 are in direct contact with the concrete, forming a "mechanical lock" effect. When the concrete is poured, the grout can be embedded in the side grooves 9, increasing the bonding area between the composite anchor plate 2 and the concrete, thereby improving the shear resistance.

[0022] Furthermore, the surface of the outer anchor plate 1 is provided with multiple threaded holes 3. The threaded holes 3 are used to provide standardized interfaces for connection with external structures, thereby increasing installation efficiency.

[0023] Furthermore, multiple reinforcing anchor bars 4 are installed between the outer anchor plate 1 and the composite anchor plate 2, located outside the connector 6. The spacing between the multiple reinforcing anchor bars 4 is greater than the spacing between the multiple pre-embedded anchor bars 5. The reinforcing anchor bars 4 enhance the connection strength between the outer anchor plate 1 and the composite anchor plate 2. The larger spacing can reduce cost pressure while ensuring stability.

[0024] Furthermore, the outer walls of the first anchor plate 201 and the second anchor plate 202 are both equipped with edge serrations 7. After the edge serrations 7 are embedded in the concrete, they form an interlocking structure of "serrations-concrete", which increases the shear resistance to a certain extent compared with smooth anchor plates.

[0025] The method of use in this embodiment is as follows: the outer anchor plate 1 serves as the top load-bearing interface, and is rigidly connected to the composite anchor plate 2 through the connector 6, forming a stable frame structure of "double-layer plate + intermediate connection". Compared with the traditional single-layer anchor plate, the overall bending stiffness is improved, effectively resisting the lateral pressure during concrete pouring and the deformation caused by external loads (such as equipment vibration and wind load), reducing the risk of embedded part displacement or breakage. The multiple embedded anchor bars 5 at the lower end of the composite anchor plate 2 are arranged in a staggered manner, avoiding the problem of local stress concentration in concrete caused by the dense arrangement of traditional anchor bars. The ends of the hook-shaped anchor bars form a mechanical interlock with the concrete, and the bonding force of a single anchor bar is improved compared with that of a straight anchor bar. Moreover, the multiple anchor bars disperse the force, reducing the probability of concrete splitting. Through the innovative features such as multi-layer composite structure design, staggered hook anchor bar layout and edge serrations 7, the system systematically solves the problems of insufficient bearing capacity, weak deformation resistance, high risk of concrete splitting and inconvenient installation of traditional straight anchor bar embedded parts. It has significant application value in industrial equipment foundations, high-rise curtain wall keels and other scenarios.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
