Description

Technical Field

[0001] The utility model relates to the technical field of prestress, in particular to a special low-retraction prestressed anchoring system for floor Background Technique

[0002] Prestress is the compressive stress pre-applied to a structure during construction to improve its service performance. During the service period of the structure, the pre-applied compressive stress can completely or partially offset the tensile stress caused by the load, avoiding structural failure. It is commonly used in concrete structures. A prestressed concrete structure is a structure that is pre-stressed before it bears the load, so that the internal force of the concrete in the tensile zone generates compressive stress when it is subjected to the external load, which is used to offset or reduce the tensile stress generated by the external load, so that the structure does not crack or cracks relatively late under normal use conditions.

[0003] When using the prestressed anchoring system for special low-retraction work on the floor, the traditional prestressed anchoring system generally performs pressure tensioning through a simple structure during use. Then, the existing equipment can only perform tensioning in a small range, and the tensioning effect is not good, resulting in a reduction in the use effect of the device, and thus it is not convenient for effective use. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem in the prior art that the traditional prestressed anchoring system generally performs pressure tensioning through a simple structure during use. Then, the existing equipment can only perform tensioning in a small range, and the tensioning effect is not good, resulting in a reduction in the use effect of the device, and thus it is not convenient for effective use. A special low-retraction prestressed anchoring system for floor is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A special low-retraction prestressed anchoring system for floor, including a fixing plate, one side outer surface of the fixing plate is fixedly connected with an anchor backing plate, an interface is opened at a position close to the center on one side outer surface of the anchor backing plate, a corrugated pipe is fixedly communicated inside the interface, one side outer surface of the fixing plate is fixedly welded with a spiral rib, and the spiral rib is sleeved on the outer surfaces of the anchor backing plate and the corrugated pipe. A baffle is fixedly connected to the outer surface of the corrugated pipe near one side edge, and the inner surface of the baffle on one side is engaged and limitedly connected with the inside of the spiral rib.

[0006] As a preferred embodiment, an opening is opened on the other side outer surface of the fixing plate, and an anchor plate is fixedly communicated inside the opening.

[0007] As a preferred embodiment, a plurality of clamping grooves are equidistantly opened on the outer surface of the anchor plate along the circumferential direction, and a spring clip is engaged and connected inside each of the plurality of clamping grooves.

[0008] As a preferred embodiment, clamping spring grooves are circumferentially formed at the edges near one side of the outer surfaces of the plurality of spring clip pieces.

[0009] As a preferred embodiment, elastic slits are horizontally formed on the outer surfaces of the plurality of spring clip pieces.

[0010] As a preferred embodiment, steel strands penetrate through the interiors of the plurality of spring clip pieces, and one end of each steel strand extends to the outside of the corrugated pipe.

[0011] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.

[0012] 1. In the present utility model, by sequentially passing the steel strands through the interiors of the spring clip pieces, the corrugated pipes, and the anchor backing plates, the steel strands can pass through the equipment well. Then, the equipment is installed in a special floor scenario. By applying pressure, the fixing plate drives the anchor backing plate to move, causing the corrugated pipes to move simultaneously. At the same time, the steel strands are tensioned under the clamping of the spring clip pieces, so that the steel strands have a certain prestress. Subsequently, under the special structure of the spring clip pieces, effective control is carried out. Through the setting of the clamping spring grooves, the spring clip pieces can be restricted during tensioning, preventing the spring clip pieces from being driven by the steel strands, and making the tensile force between the steel strands and the spring clip pieces tighter and tighter. Thus, the device is convenient for effective use, improving the reaction effect of the prestress of the device, reducing the retraction effect of the steel strands, and further improving the use effect of the device.

[0013] 2. In the present utility model, after the steel strands are tensioned, the fixing plate drives the anchor backing plate to move. Under the action of the spiral reinforcement, the equipment has a certain elastic effect. Thus, when the fixing plate moves, there is a certain retained value of the tensile force, enabling the fixing plate to be used safely during movement. Therefore, the device is convenient for effective use, improving the use effect of the device. At the same time, under the buffering effect of the corrugated pipes, the steel strands are better protected during use, improving the use effect of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to more clearly understand the above-mentioned objects, features and advantages of this utility model, the following further describes this utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of this application and the features in the embodiments can be combined with each other.

[0019] In the following description, many specific details are set forth in order to fully understand this utility model. However, this utility model can also be implemented in other ways different from those described herein. Therefore, this utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0020] Embodiment 1, as Figure 1-2 shown, this utility model provides a special low-retraction prestressed anchoring system for floor slabs, including a fixed plate 1. One side outer surface of the fixed plate 1 is fixedly connected with an anchor backing plate 2. An interface 13 is opened at a position close to the center on one side outer surface of the anchor backing plate 2. A bellows 3 is fixedly communicated inside the interface 13. One side outer surface of the fixed plate 1 is fixedly welded with a spiral reinforcement 4, and the spiral reinforcement 4 is sleeved on the outer surfaces of the anchor backing plate 2 and the bellows 3. A baffle 5 is fixedly connected to the outer surface of the bellows 3 close to one side edge, and the inner surface of the baffle 5 is snap-fitted and restricted to connect with the inside of the spiral reinforcement 4. An opening 12 is opened on the other side outer surface of the fixed plate 1, and an anchor plate 6 is fixedly communicated inside the opening 12.

[0021] The effect achieved by the entire Embodiment 1 is that when the device is in use, first, the steel strand 9 is passed through the inside of the spring clip 8, the corrugated pipe 3, and the anchor backing plate 2 in sequence, so that the steel strand 9 can pass through the device well. Then, the device is installed in a special floor scenario. By applying pressure, the fixing plate 1 drives the anchor backing plate 2 to move, causing the corrugated pipe 3 to move simultaneously. At the same time, the steel strand 9 is tensioned under the clamping of the spring clip 8, so that the steel strand 9 has a certain prestress. Then, it is effectively controlled under the special structure of the spring clip 8. Through the setting of the snap ring groove 10, the spring clip 8 can be restricted during tensioning, so that the spring clip 8 will not be driven by the steel strand 9, and the tensile force between the steel strand 9 and the spring clip 8 becomes tighter and tighter. Thus, the device is convenient for effective use, improving the reaction effect of the prestress of the device, reducing the retraction effect of the steel strand 9, and further improving the use effect of the device.

[0022] Embodiment 2 is as follows Figure 1-3 As shown in the figure, a plurality of card slots 7 are equidistantly arranged on the outer surface of one side of the anchor plate 6 along the circumferential direction. A spring clip 8 is snap-fitted inside each of the plurality of card slots 7. A snap ring groove 10 is arranged on the outer surface of each of the plurality of spring clips 8 along the circumferential direction near the edge of one side. An elastic slit 11 is arranged on the outer surface of each of the plurality of spring clips 8 along the horizontal direction. A steel strand 9 passes through the inside of each of the plurality of spring clips 8, and one end of the steel strand 9 extends to the outside of the corrugated pipe 3.

[0023] The effect achieved by the entire Embodiment 2 is that when the device is in use, after the steel strand 9 is tensioned first, the fixing plate 1 drives the anchor backing plate 2 to move. Under the action of the spiral stirrup 4, the device has a certain elastic effect. Thus, when the fixing plate 1 moves, there is a certain tensile force retention value, so that the fixing plate 1 can be used safely when moving. Thus, the device is convenient for effective use, improving the use effect of the device. At the same time, under the buffering effect of the corrugated pipe 3, the steel strand 9 has better protection during use. Through the restriction of the baffle 5, the spiral stirrup 4 and the corrugated pipe 3 will not be overused, improving the use effect of the device.

[0024] The above are only the preferred embodiments of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
