Description

Technical Field

[0001] The utility model relates to the technical field of embedded parts, in particular to an embedded part in concrete. Background Art

[0002] As is well known, the concrete embedded part is an embodiment of building industrialization. In its production process, intensive utilization of resources and energy conservation can be achieved. Through factory production methods, dust and noise pollution at the construction site can be reduced, and energy consumption and carbon emissions during the construction process can be lowered. By optimizing the design and construction plan, while meeting the building function requirements, the concrete embedded part is expected to be more widely applied and further developed in terms of building industrialization, resource conservation, environmental protection, etc. For structures that need to reserve a large number of embedded parts, how to improve the production efficiency of concrete embedded parts and the reliability of the anchorage of embedded parts has become an urgent problem to be studied.

[0003] Such as Figure 1 shown, the Chinese utility model patent discloses an embedded part positioning device and a wall panel with the embedded part positioning device (publication (announcement) number CN211923028U). The embedded part positioning device includes: an embedded part body 1; wherein, a plurality of locking mechanisms 2 are arranged on the embedded part body 1 to lock the embedded part body 1 to the formwork 31 of the wall panel 3, so as to realize the positioning and fixation of the embedded part body. It passes through the connecting rod 21 and the locking piece 22 of the locking mechanism 2; the connecting rod 21 is used to penetrate through the formwork 31 to realize the positioning between the formwork 31 and the embedded part body 1; the locking piece 22 is connected to the connecting rod 21 in a position-adjustable manner along the length direction of the connecting rod 21 to clamp the formwork 31 between the locking piece 22 and the embedded part body 1 to realize the fixation of the embedded part body 1, thereby avoiding the displacement of the embedded part body during concrete pouring, and at the same time facilitating the later treatment to realize the recovery and reuse of the locking mechanism.

[0004] However, when the inventor specifically implemented this device, it was found that there were the following defects: Concrete components often need to be connected to steel structural components through steel embedded parts embedded in the concrete; the form of the embedded parts is usually anchor bars welded on a steel plate. The straight anchor bar anchorage length should not be less than the tensile anchorage length; when the end of the steel bar adopts a hook or mechanical anchorage measure, the anchorage length including the hook or the anchorage end can be taken as 60% of the basic anchorage length. In the case of a relatively thin concrete component, it is difficult for the anchorage depth of the anchor bar to meet the specification requirements, and the anchorage effect cannot be guaranteed.

[0005] Moreover, precast concrete components often need to be connected to steel structural components through steel embedments embedded in the concrete. Usually, before pouring the concrete or placing the steel reinforcement cage, the steel embedments need to be temporarily or permanently fixed in the precast concrete component mold manually, which leads to an increase in processes and time consumption. Especially when the number of embedments is large, the production efficiency of precast concrete components will be reduced. Summary of the Invention

[0006] In view of the deficiencies of the prior art, the utility model provides a steel embedment in concrete with a more scientific and reasonable structure, which improves the anchorage reliability of the embedment and reduces the requirement of the anchorage depth for the thickness of the concrete component.

[0007] To achieve the above object, the utility model provides the following technical solution: A steel embedment in concrete, comprising:

[0008] A steel plate, which is exposed on the outer surface of the concrete structure;

[0009] An anchor plate, which is integrally connected to the steel plate; there are multiple anchor plates, and a spacing allowing the passage of concrete aggregate is left between the multiple anchor plates, and the anchor plates are perpendicularly arranged to the steel plate;

[0010] Studs, which are installed on the anchor plate; there are multiple studs, and the studs are perpendicularly arranged to the anchor plate; further, the steel plate and the anchor plate can be connected by welding or integrally connected by bolts; multiple anchor plates are evenly distributed on the steel plate at equal intervals; the anchor plates and the studs are placed inside the concrete structure;

[0011] As a preferred solution, the studs are located at the upper and lower end faces of the anchor plate, and the studs at the upper and lower end faces of the anchor plate are arranged in rows and staggered; further, the studs can also be arranged on one side of the end face of the anchor plate.

[0012] As a preferred solution, screw holes are provided on the anchor plate, and the studs are screwed into the screw holes on the anchor plate;

[0013] As a preferred solution, the studs are welded and installed on the anchor plate.

[0014] As a preferred solution, nuts are provided at the tops of the studs.

[0015] As a preferred solution, the steel embedment in concrete includes a magnet, which is arranged outside the steel plate, fixes the steel plate by magnetic force, and is removed after the concrete begins to set.

[0016] As a preferred solution, it further includes a steel mold, and the steel plate is adsorbed on the inner wall of the steel mold by the magnet.

[0017] As a preferred solution, a pull ring is provided on the magnet.

[0018] As a preferred solution, the magnet is made of neodymium iron boron material.

[0019] The beneficial effects achieved by the present invention are as follows:

[0020] Compared with the prior art, the present utility model provides a pre-embedded part in concrete, which has the following beneficial effects: for this pre-embedded part in concrete, the pre-embedded part in the form of a studded anchor plate adopted in this case converts the anti-slip force between the anchor plate and the concrete into the contact pressure between the stud and the concrete. Under the action of an external tensile force, the stud is mainly subjected to tensile and shear forces, and the concrete in contact with it is mainly subjected to compressive forces. The two materials each exert their good mechanical properties, greatly increasing the reliability of the connection between the anchor plate and the concrete and improving the ultimate bearing capacity of the connection of the embedded part.

[0021] Compared with the traditional method where only the end of the steel bar adopts a hook or mechanical anchoring measure, although their action mechanisms are the same, the studs with a larger number and evenly arranged increase the contact area between the cross-section and the concrete, and multiple studs work together to bear the force, improving the connection bearing capacity between the two; when the size of the concrete member is relatively thin, the reliability of the anchoring of the embedded part in the concrete can be ensured by adopting this kind of pre-embedded part in the form of a studded anchor plate.

[0022] The pre-embedded part in concrete provided by the present utility model does not need to be drilled on the steel plate mold compared with the prior art, will not damage the formwork, and is conducive to the reuse of the formwork; moreover, the magnet adopted can be removed after the initial setting of the concrete, and only simple cleaning work needs to be done at the embedded part, without other treatment work. Compared with the external extension screw used to fix the embedded part in the prior art, which is not an actually required component, but since it is welded to the embedded plate, the external extension screw needs to be removed after use, and then the cutting work of the external extension screw needs to be carried out, and this may cause damage to the concrete. Compared with this solution, there is one more post-treatment process, which is not conducive to improving efficiency. Brief Description of the Drawings

[0028] In order to enable those skilled in the art to better understand the solution of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0029] As Figure 1 shown, an embedded part positioning device described in the background technology and a wall panel having the embedded part positioning device; concrete components often need to be connected to steel structure components through steel embedded parts embedded in concrete; the form of the embedded parts is usually anchor bars welded on a steel plate. The straight anchor bar anchorage length should not be less than the tensile anchorage length; when the end of the steel bar adopts a hook or mechanical anchorage measure, the anchorage length including the hook or the anchorage end can be taken as 60% of the basic anchorage length. In the case where the concrete component is relatively thin, it is difficult for the anchor bar anchorage depth to reach the specification requirements, and the anchorage effect cannot be guaranteed.

[0030] To solve this technical problem, the present utility model provides a concrete embedded part, which is applied to a concrete structure.

[0031] Specifically, please refer to Figure 2-3 , the concrete embedded part specifically includes:

[0032] A steel plate 1, and the steel plate 1 is exposed on the outer surface of the concrete structure;

[0033] An anchor plate 2, and the anchor plate 2 is integrally connected with the steel plate 1; there are multiple anchor plates 2, and a spacing allowing concrete aggregate to pass through is left between the multiple anchor plates 2, and the anchor plate 2 is perpendicularly arranged with respect to the steel plate 1;

[0034] A stud 3, and the stud 3 is installed on the anchor plate 2; there are multiple studs 3, and the stud 3 is perpendicularly arranged with respect to the anchor plate 2; further, the steel plate 1 and the anchor plate 2 can be welded or integrally connected by bolts; the multiple anchor plates 2 are evenly distributed on the steel plate 1 at equal intervals; the anchor plate 2 and the stud 3 are placed inside the concrete structure.

[0035] The embedded part in concrete provided by the present utility model adopts an embedded part in the form of an anchor plate 2 with stud 3, which converts the anti-slip force between the anchor plate 2 and the concrete into the contact pressure between the stud 3 and the concrete. Under the action of an external tensile force, the stud 3 is mainly subjected to tensile and shear forces, and the concrete in contact with it is mainly subjected to compressive forces. The two materials each exert their good mechanical properties, greatly increasing the reliability of the connection between the anchor plate 2 and the concrete and improving the ultimate bearing capacity of the embedded part connection. Compared with the traditional method of only using a hook or mechanical anchoring measure at the end of the steel bar, although their action mechanisms are the same, the numerous and evenly arranged studs 3 increase the contact area between the cross-section and the concrete, and the multiple studs 3 work together to bear the force, improving the connection bearing capacity of the two. When the size of the concrete member is relatively thin, the reliability of the anchoring of the embedded part in the concrete can be ensured by adopting such an embedded part in the form of a stud 3 and an anchor plate 2. Similarly, such embedded parts can also be used in cast-in-place concrete structures.

[0036] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0037] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.
