Description

Technical Field

[0001] This utility model belongs to the field of building embedded parts technology, specifically relating to an anti-displacement embedded component for precast concrete. Background Technology

[0002] To strengthen the connection between precast concrete components and the main steel structure, embedded parts are usually installed in the precast concrete components. The embedded parts need to be firmly positioned before pouring, and sometimes methods such as spot welding of steel bars or temporary binding of support frames are used. However, there are problems such as overall instability and positional displacement of the embedded parts, which cannot meet the requirements of welding or bolting of connecting parts later.

[0003] The document with authorization announcement number CN209920193U discloses a structural device for fixing embedded parts in precast concrete, including a nut, a screw rod, a bolt, and a mold panel. The mold panel has a circular hole, the nut is welded to one side of the mold panel, the screw rod corresponds to the nut and is sleeved in the nut, the screw rod has a through hole, and the bolt is disposed in the through hole. The center lines of the screw rod, bolt, nut, and circular hole are all located on the same axis. The embedded part is fixed by passing it through the nut and the bolt through the circular hole of the screw rod, and then the screw rod is tightened to the nut welded to the mold panel.

[0004] However, this device still has at least the following problems: First, after the pouring is completed, the removal of the nut and the formwork is time-consuming and labor-intensive because they are welded together. Second, during the pouring process, the embedded parts are prone to displacement or tilting due to concrete vibration or the impact of pouring. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to provide an anti-displacement embedded component for precast concrete, which aims to enhance the stability of the embedded component by strengthening the connection with the formwork, while avoiding problems such as damage to the edges and corners of the concrete component due to obstruction of the embedded component during demolding.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] An anti-displacement embedded component for precast concrete is provided for connection with a formwork, wherein the formwork includes at least a bottom formwork and a side formwork connected to the bottom formwork; the embedded component includes a supporting base plate located at the upper end of the bottom formwork, a connecting side plate connected to the side end of the supporting base plate and abutting the side formwork, and a connecting structure for connecting the side formwork and the connecting side plate; the connecting structure includes a connecting screw; the side formwork and the connecting side plate are respectively provided with a first mounting hole and a second mounting hole for the connecting screw to pass through, and the connecting screw is provided with at least one fixing nut abutting against the surface of the connecting side plate away from the side formwork, and the connecting screw is also provided with at least one limiting nut or limiting block abutting against the surface of the side formwork away from the connecting side plate.

[0008] As a further preferred embodiment of the present invention, the embedded component further includes a transverse embedded rib disposed on the supporting base plate and extending in a direction away from the connecting side plate.

[0009] As a further preferred embodiment of this utility model, the length of the connecting screw is 0.1 to 0.3 times the length of the transverse pre-embedded rib.

[0010] As a further preferred embodiment of this invention, the first mounting hole is a strip-shaped hole with a height greater than the diameter of the connecting screw.

[0011] As a further preferred embodiment of the present invention, the pre-embedded component further includes a connecting sleeve installed on the connecting screw, the connecting sleeve having a third mounting hole through which the connecting screw passes, and one end of the connecting sleeve being connected to the connecting side plate, and the other end abutting against the fixing nut.

[0012] As a further preferred embodiment of this utility model, the length of the connecting sleeve is less than or equal to the length of the supporting base plate.

[0013] As a further preferred embodiment of this utility model, the connecting sleeve is provided with a positioning groove that is adapted to the fixing nut so that the fixing nut can be screwed in, and the positioning groove communicates with the third mounting hole.

[0014] As a further preferred embodiment of this utility model, a sealing ring is sleeved on the connecting screw, located in the positioning groove and abutting against the fixing nut.

[0017] The beneficial effects of this utility model are:

[0018] This utility model enhances the tightness of the connection between the embedded components and the template in terms of both contact area and connection strength through the structure formed by the supporting base plate and the connecting side plate, as well as the connection method between the structure and the template. This ensures that the embedded components will not shift or tilt due to factors such as vibration during pouring. At the same time, the embedded components themselves have a simple structure, and some components can be quickly disassembled and recycled after pouring, which has the advantages of good economy and strong practicality.

[0019] The embedded component provided by this utility model has good compatibility, and its flat surface can be exposed on the surface of the poured concrete component, which facilitates the rapid positioning of the embedded component. At the same time, the flat surface can avoid damage to the edges and corners during demolding. Attached Figure Description

[0033] Example 1

[0034] As attached Figure 1 ~Appendix Figure 3 As shown, this embodiment provides an anti-displacement embedded component for precast concrete, which is used to connect with a template 100. The template 100 includes at least a bottom template 110 and a side template 120 connected to the bottom template 110.

[0035] The embedded component includes a supporting base plate 210 located at the upper end of the bottom template 110, a connecting side plate 220 connected to the side end of the supporting base plate 210 and abutting the side template 120, and a connecting structure for connecting the side template 120 and the connecting side plate 220; the connecting structure includes a connecting screw 230; the side template 120 and the connecting side plate 220 are respectively provided with a first mounting hole 231 and a second mounting hole 232 for the connecting screw 230 to pass through, and the connecting screw 230 is provided with at least one fixing nut 233 abutting against the surface of the connecting side plate 220 away from the side template 120, and the connecting screw 230 is also provided with at least one limiting nut or limiting block 234 abutting against the surface of the side template 120 away from the connecting side plate 220; the embedded component also includes a transverse embedded rib 240 provided on the supporting base plate 210 and extending away from the connecting side plate 220. In this configuration, with the side formwork 120 erected horizontally and the connecting side plate 220 erected vertically, the supporting base plate 210 is installed horizontally, the connecting side plate 220 is installed vertically, and the horizontal embedded reinforcement 240 is also installed horizontally. These reinforcement bars are fixed to the supporting base plate 210 using common methods such as welding, with at least two bars to enhance connection strength. The supporting base plate 210 and connecting side plate 220 are pre-connected using welding or integral molding, forming an angle structure that matches the angle of the corner plate structure with the formwork 100. This ensures that the supporting base plate 210 and connecting side plate 220 of the corner plate structure abut against the bottom formwork 110 and side formwork 120, respectively. After connection, the embedded components will not shift or tilt in either the vertical or horizontal directions due to concrete vibration, ensuring accurate positioning of the embedded components. On the other hand, since the connecting side plate 220 abuts against the side formwork 120, after the pouring is completed and the formwork is demolded, the surface of the connecting side plate 220 of the embedded part can be flush with the surface of the concrete component, and the exposed surface of the embedded part helps to quickly position it during on-site construction.

[0036] The embedded components are connected to the side formwork 120 via a connecting structure. The length of the connecting bolt 230 is 0.1 to 0.3 times the length of the transverse embedded reinforcement 240, or it can be chosen to be approximately the same length as the supporting base plate 210. This has the advantage that, as shown in the attached... Figure 3 As shown, after the pouring is completed, the connecting screw 230 can be removed from the concrete component and recycled. A column cavity left by the connecting screw 230 will be formed inside the concrete component. This column cavity has a certain length, which can improve the connection convenience and connection strength when the subsequent embedded components are connected to other structures.

[0037] In one embodiment, the first mounting hole 231 is a strip-shaped hole with a height greater than the diameter of the connecting screw 230. The advantage of this design is that it facilitates the adjustment of the height position of the angle plate structure formed by the connection of the supporting base plate 210 and the connecting side plate 220, ensuring that the supporting base plate 210 can be fitted and connected to the upper surface of the bottom template 110.

[0038] Example 2

[0039] This embodiment provides another implementation method based on Embodiment 1, adding a structure, as shown in the attached diagram. Figure 4 As shown, specifically, it includes a connecting sleeve 250 installed on the connecting screw 230. The connecting sleeve 250 is provided with a third mounting hole 251 through which the connecting screw 230 passes. One end of the connecting sleeve 250 is connected to the connecting side plate 220, and the other end abuts against the fixing nut 233. The length of the connecting sleeve 250 is less than or equal to the length of the supporting base plate 210. The connecting sleeve 250 helps to strengthen the connection between the pre-embedded component and the side formwork 120 before pouring, improves the positioning accuracy of the pre-embedded component, and also helps to improve the connection strength when the pre-embedded component is subsequently connected to other structures.

[0040] Furthermore, the connecting sleeve 250 is provided with a positioning groove 252 that is adapted to the fixing nut 233 so that the fixing nut 233 can be screwed in, and the positioning groove 252 communicates with the third mounting hole 251. A sealing ring 253 is sleeved on the connecting screw 230, located within the positioning groove 252 and abutting against the fixing nut 233. This arrangement enhances the sealing performance of the connecting sleeve 250, preventing cement from entering the third mounting hole 251 during pouring, and ensuring that the connecting screw 230 can be quickly removed and recycled during disassembly.

[0041] Example 3

[0042] This embodiment is a structural optimization based on Embodiment 1 or Embodiment 2, as shown in the attached figure. Figure 5 As shown, specifically as follows: The embedded component also includes a support rod 260 and a support cylinder 261. The support cylinder 261 is provided with a blind hole 262 that is slidably connected to the support rod 260. A spring 263 that is connected to the support rod 260 is provided in the blind hole 262.

[0043] One of the support rod 260 and the support cylinder 261 is connected to the connecting screw 230 or the connecting sleeve 250, and one of the support rod 260 and the support cylinder 261 is connected to the bottom template 110. More preferably, the support rod 260 is connected to the connecting screw 230 or the connecting sleeve 250, and the support cylinder 261 is connected to the bottom template 110.

[0044] The structure described in this embodiment is primarily designed for situations where the embedded component is deeply embedded in the template 100 or requires a high positioning position. Without altering the specifications of the embedded component, this structure enables the connection between the embedded component and the bottom template 110, ensuring the embedded component still provides support in both directions. It is worth noting that when the support rod 260 is connected to the connecting screw 230, the fixing nut 233 must first be screwed onto the connecting screw 230 near the side template 120. When the support rod 260 is connected to the connecting sleeve 250, a insertion hole can be provided on the surface of the connecting sleeve 250 to allow the support rod 260 to be inserted, enhancing the connection strength. The support rod 260 and the support sleeve 261 are detachably connected, and the connection between the support rod 260 and the connecting sleeve 250 and the bottom template 110 is also detachable, facilitating the installation of the above structure on the embedded component according to actual needs and improving the practicality of the device. The aforementioned overall structure not only improves the tightness of the connection between the embedded components and the bottom formwork, but also provides a certain buffering effect during cement vibration, thereby enhancing the stability of the embedded components.

[0045] In a preferred embodiment, the support base plate 210 is provided with a limiting hole 264 for the support rod 260 to pass through, and the support rod 260 is provided with an external thread section 265, on which an installation nut 266 is screwed to the external thread section 265 to abut against the support base plate 210. This arrangement helps to strengthen the connection between the support rod 260 and the support base plate 210, providing a certain degree of support for the support base plate 210.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
