Description

Technical Field

[0001] This utility model relates to the technical field of embedded parts, specifically to a connection structure for offset embedded parts. Background Technology

[0002] Embedded parts are widely used in concrete structures in fields such as building construction, electromechanical equipment engineering, and curtain wall engineering, serving as important connection nodes for the installation of subsequent components. Typically, during the main structure construction phase, the embedded steel plates need to be accurately positioned according to the design and connected to the subsequent structural components by welding or bolting to complete the overall installation.

[0003] During actual construction, due to factors such as measurement deviations, construction errors, formwork deformation, and reinforcement interference, embedded parts are prone to varying degrees of planar positional deviation, resulting in mismatch with the positions of subsequent components and affecting construction progress and structural reliability. Especially in projects with high precision requirements such as curtain walls and equipment supports, embedded part misalignment can directly lead to positioning failures, increased rework rates, and significantly impact construction efficiency and quality. Traditional solutions, such as on-site welding, grooved reinforcement, or removal and re-embedding, are not only complex and time-consuming but may also affect the overall stability and safety of the structure, even causing irreparable quality problems. Utility Model Content

[0004] Based on the above description, this utility model provides a connection structure for offset embedded parts, which solves the problems of complex construction operations, long construction period, and potential impact on the overall stability and safety of the structure caused by traditional methods of resolving embedded part offset.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: This application provides a connection structure for offset embedded parts, and the technical solution adopted is as follows: An off-center embedded part connection structure includes: An embedded plate, wherein multiple anchoring steel bars are connected to the embedded plate, and the embedded plate and the anchoring steel bars are embedded in the building component; The adapter has at least two mounting holes. The adapter fits into the embedded plate and is connected to the embedded plate by connecting bolts. The number of connecting bolts is the same as the number of mounting holes.

[0007] Preferably, one end of the embedded sleeve is welded and fixed to the embedded plate, and this end is flush with the side of the embedded plate away from the building component.

[0008] Preferably, the number of anchoring steel bars and the number of pre-embedded sleeves are the same and they are fixedly connected in a one-to-one correspondence.

[0009] Preferably, one end of the anchoring steel bar is threaded, and the anchoring steel bar is threadedly connected to the pre-embedded sleeve.

[0010] Preferably, one end of the pre-embedded steel bar is connected to the pre-embedded plate, and the other end is connected to an anchor.

[0011] Preferably, the anchor includes an anchor bar or an anchor head.

[0012] Preferably, the adapter includes an adapter plate, which is parallel to and fits against the embedded plate. The adapter plate has two mounting plates, which are perpendicular to the length direction of the mounting hole.

[0013] Preferably, it also includes a keel, which is disposed between the two mounting plates and is connected to the two mounting plates by fixing bolts.

[0014] Preferably, the connecting hole is an oblong hole, and the length direction of the connecting hole is perpendicular to the adapter plate.

[0015] Compared with the prior art, the technical solution of this application has at least the following beneficial technical effects: This application embeds a pre-embedded plate and anchoring steel bars within a building component, serving as a foundation support structure to transfer loads to the component. An adapter is used to connect to the embedded plate via bolts. The adapter, acting as a direct connector to subsequent components, directly bears the load and transfers it to the embedded plate through the bolts. The adapter has a connecting hole for the bolts to pass through, and this hole is oblong, allowing the adapter to move relative to the embedded plate along its length.

[0023] Reference Figure 1 As shown, this application provides a misaligned embedded part connection structure, including an embedded plate 1 and a transition piece. The embedded plate 1 is connected to a plurality of anchoring steel bars 2, and the embedded plate 1 and the anchoring steel bars 2 are embedded in the building component. The transition piece is provided with at least two mounting holes 31. The transition piece fits against the embedded plate 1 and is connected to the embedded plate 1 by connecting bolts 4. The number of connecting bolts 4 is the same as the number of mounting holes 31, and the connecting bolts 4 pass through the mounting holes 31 one by one to connect with the embedded plate 1.

[0024] Reference Figure 1 and Figure 2 As shown, in order to facilitate the fixed connection between the connecting bolt 4 and the embedded plate 1, the embedded plate 1 is provided with an embedded sleeve 5 for the connecting bolt 4 to be connected. The number of embedded sleeves 5 is the same as the number of connecting bolts 4 and they correspond one-to-one. The embedded sleeves 5 pass through the embedded plate 1 and are embedded in the building components. The inner wall of the embedded sleeves 5 is provided with threads.

[0025] The inner diameter of the pre-embedded sleeve 5, the diameter of the mounting hole 31, and the diameter of the connecting bolt 4 are matched to ensure connection stability.

[0026] Reference Figure 2 As shown, the embedded sleeve 5 is welded and fixed to the embedded plate 1, and the axis of the embedded sleeve 5 is perpendicular to the embedded plate 1. Specifically, one end of the embedded sleeve 5 is welded and fixed to the embedded plate 1, and this end is flush with the side of the embedded plate 1 away from the building component, that is, the embedded sleeve 5 does not protrude from the side of the embedded plate 1 where it meets the adapter. In actual processing, the embedded sleeve 5 is welded and fixed to the embedded plate 1 through plug welding holes or other conventional welding methods to ensure the connection strength between the embedded sleeve 5 and the embedded plate 1.

[0027] Reference Figure 2As shown, one end of the anchoring steel bar 2 is fixedly connected to the embedded plate 1, and the axis of the anchoring steel bar 2 is perpendicular to the embedded plate 1. Specifically, the number of anchoring steel bars 2 and the number of embedded sleeves 5 are the same, and they are fixedly connected one-to-one. The anchoring steel bar 2 can be welded to the end of the embedded sleeve 5 away from the embedded plate 1, or a thread can be provided at one end of the anchoring steel bar 2, and the anchoring steel bar 2 and the embedded sleeve 5 can be threadedly connected. In this embodiment, the threaded connection between the anchoring steel bar 2 and the embedded sleeve 5 is used for illustration.

[0028] With this setup, the anchoring steel bar 2 is directly fixed to the embedded sleeve 5. The embedded sleeve 5 and the anchoring steel bar 2 form an integral anchoring structure that is anchored into the building component. This not only ensures the anchoring strength of the embedded plate 1, but also improves the anchoring strength of the embedded sleeve 5, thereby ensuring the fixing strength and stability of the connecting bolt 4 and the adapter on the building.

[0029] Reference Figure 2 As shown, furthermore, the end of the anchoring steel bar 2 furthest from the embedded plate 1 is connected to an anchoring member, which is used to enhance the anchoring strength of the anchoring steel bar 2 within the building component. Specifically, the anchoring member can be an anchor bar 21 or an anchor head. The anchor bar 21 is welded to the anchoring steel bar 2 along the edge, and the anchor head is directly welded and fixed to the anchoring steel bar 2. This embodiment uses the anchor bar 21 for illustration.

[0030] Reference Figure 2 As shown, during the pre-embedded construction, after the anchoring steel bar 2 and the pre-embedded sleeve 5 are connected, the whole assembly is pre-embedded in the concrete beam or other structural components according to the design layout. The end of the pre-embedded sleeve 5 near the pre-embedded plate 1 can be sealed with a plug 13 to prevent contamination or damage to the threads during the construction stage.

[0031] In this embodiment, four embedded sleeves 5 are provided on the embedded plate 1 for illustration. The four embedded sleeves 5 are distributed in a rectangular shape on the surface of the embedded plate 1.

[0032] Reference Figure 1 and Figure 3 As shown, the number of mounting holes 31 on the adapter is set according to the number of embedded sleeves 5, and the mounting holes 31 correspond one-to-one with the embedded sleeves 5, so that the connecting bolts 4 can pass through the mounting holes 31 and connect to the corresponding embedded sleeves 5.

[0033] Reference Figure 1 and Figure 3 As shown, in this embodiment, the adapter is an adapter plate 3. During installation, the adapter plate 3 is parallel to and fits against the embedded plate 1, ensuring that the mounting holes 31 correspond one-to-one with the embedded sleeves 5. Multiple connecting bolts 4 are passed through the corresponding mounting holes 31 and connected to the embedded sleeves 5, thereby connecting the adapter plate 3 to the embedded plate 1. A gasket 6 is placed between the connecting bolts 4 and the adapter plate 3 to improve connection strength and stability.

[0034] Reference Figure 3 and Figure 4 As shown, the mounting holes 31 are further designed as oblong holes, and the length directions of the multiple mounting holes 31 are parallel. The oblong design of the mounting holes 31 allows the adapter to move relative to the embedded plate 1 along the length direction of the oblong hole. During actual installation, the length direction of the oblong hole is horizontal. The adapter, as a component directly connected to the subsequent components, directly bears the load and transfers the load to the embedded plate 1 through the connecting bolts 4. The horizontal position of the adapter can be adjusted to match the installation position of the subsequent components, ensuring the smooth installation of the subsequent components.

[0035] Reference Figure 1 , Figure 3 and Figure 5 As shown, in order to facilitate the installation of subsequent components on the adapter plate 3, the adapter plate 3 is provided with two mounting plates 7. The mounting plates 7 are perpendicular to the length direction of the mounting holes 31. The two mounting plates 7 are distributed at intervals along the length direction of the mounting holes 31. The mounting plates 7 are provided with connecting holes 71. The connecting holes 71 on the two mounting plates 7 are coaxially arranged.

[0036] Reference Figure 1 , Figure 3 and Figure 5 As shown, specifically, the mounting plate 7 is fixed to the adapter plate 3 via the connecting plate 8. The connecting plate 8 is parallel to and fits the adapter plate 3. The connecting plate 8 and the adapter plate 3 are welded and fixed. The mounting plate 7 and the connecting plate 8 are integrally formed to ensure a reliable connection between the mounting plate 7 and the adapter plate 3.

[0037] Reference Figure 1 , Figure 3 and Figure 5 As shown, a keel 9 is further provided between the two mounting plates 7, and the keel 9 is connected to the two mounting plates 7 by fixing bolts 10. Specifically, the keel 9 is a rod with a rectangular cross-section. The keel 9 is located between the two mounting plates 7, and the fixing bolts 10 pass through the connecting hole 71 of one mounting plate 7, the hole on the keel 9, and the connecting hole 71 on the other mounting plate 7 in sequence. Nuts are connected to the fixing bolts 10 to achieve the fixed installation of the keel 9 between the two mounting plates 7.

[0038] Reference Figure 3 and Figure 5 As shown, each mounting plate 7 has at least two connecting holes 71. The mounting holes 31 on the two mounting plates 7 are coaxial and correspond one-to-one. The number of fixing bolts 10 is set according to the number of connecting holes 71 on one mounting plate 7. Multiple fixing bolts 10 can ensure a reliable connection between the keel 9 and the two mounting plates 7. In this embodiment, it is illustrated that each mounting plate 7 has two connecting holes 71, and the two connecting holes 71 are spaced apart along a direction parallel to the adapter plate 3.

[0039] Reference Figure 1 and Figure 3As shown, washers 11 are provided between the head of the fixing bolt 10 and the mounting plate 7 near the head, and between the nut and the mounting plate 7 near the nut. Both fixing bolts 10 pass through the two washers 11, ensuring a reliable connection between the fixing bolts 10 and the mounting plates 7. Elastic washers 126 are provided between the keel 9 and the two mounting plates 7, serving as buffers, shock absorbers, and insulators.

[0040] Reference Figure 5 As shown, the connecting hole 71 is further designed as an oblong hole, with its length direction perpendicular to the adapter plate 3. The oblong design of the connecting hole 71 allows the fixing bolt 10 to move relative to the mounting plate 7 within the connecting hole 71 in a direction perpendicular to the adapter plate 3. This, in turn, allows the keel 9 to move relative to the adapter plate 3 and the embedded plate 1 in a direction perpendicular to the adapter plate 3. The keel 9 serves as the installation base for subsequent components, further matching the installation position of subsequent components and ensuring precise positioning and installation of the subsequent components.

[0041] After the subsequent components are installed, the load falls directly on the keel 9 and is transferred to the mounting plate 7 through the fixing bolts 10. It is then transferred to the transition plate 3 through the mounting plate 7 and the connecting plate 8, and finally to the embedded steel plate through the transition plate 3 and the connecting bolts 4. Finally, the load is evenly transferred to the concrete structural member through the embedded plate 1, the embedded sleeve 5 and the anchoring steel bar 2, so as to achieve stable installation of the subsequent components under the condition of deviation and ensure the installation accuracy and structural safety of the subsequent components.

[0042] In actual construction, if the positions of multiple embedded sleeves 5 on the embedded plate 1 are not offset from the design position or the offset is within the allowable error range, the adapter plate 3 can be omitted, and the subsequent components can be directly installed onto the embedded plate 1 by connecting bolts 4, which has greater construction flexibility.

[0043] The offset embedded part connection structure in this embodiment has the following advantages: 1. Enhance structural adaptability and ensure prefabrication quality. Compared with on-site drilling or post-installation, standardized processing of each component is completed in the factory prefabrication stage. The embedded sleeve 5 is firmly bonded to the steel plate, ensuring the processing quality and accuracy of each component, improving the overall processing quality of embedded parts, reducing on-site construction procedures, ensuring structural reliability, and reducing the complexity of later processing.

[0044] 2. Achieve offset compensation and flexible construction. Utilizing the pre-embedded sleeve 5 as the connection base point, the connection position can be flexibly adjusted via the adapter plate 3 to adapt to offset situations, achieving a mechanical connection. The structure is stable, installation is convenient, no welding is required, concrete damage is avoided, and construction flexibility and on-site adaptability are significantly improved.

[0045] 3. Reduce overall construction costs. All core components can be prefabricated in the factory, reducing on-site processing and welding work, improving installation efficiency, and lowering the technical threshold for personnel. The construction cycle is short, quality is highly controllable, and labor costs are low.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
