Description

Technical Field

[0001] This utility model relates to the field of building reinforcement technology, specifically an external prestressed reinforcement structure. Background Technology

[0002] Prestressed reinforcement is a process that uses externally added prestressed steel strands or steel struts to reinforce buildings such as houses and bridges. Its core principle is to force the added part to bear the force through prestressing, thereby changing the internal force distribution of the original structure and reducing the stress level of the original structure. It has the characteristics of improving load-bearing capacity, simple construction and safety and reliability.

[0003] When using existing prestressed steel strands to reinforce buildings, the anchorage ends of the steel strands are usually exposed or treated by casting concrete with formwork. The exposed anchorage ends are prone to rusting of the iron anchors, affecting the anchorage effect, reducing service life, and posing safety hazards. On the other hand, the method of protecting the anchorage section by casting concrete with formwork will create protruding bumps in the wall, affecting aesthetics and making it easy for water to accumulate, allowing rainwater to seep into the building and affecting its service life. Therefore, there is an urgent need for a reinforcement process that can protect the anchorage ends of prestressed reinforced structures to solve these problems. Utility Model Content

[0004] In view of the problem that the existing methods for treating the anchoring ends of prestressed steel strands can easily affect the service life and building safety, this utility model provides an external prestressed reinforcement structure.

[0005] This utility model discloses an external prestressed reinforcement structure comprising: a tensioning assembly, an anchoring groove, and an anchoring assembly. The tensioning assembly includes a connector, a deflector, and a tensioning member. The connector is disposed on the floor surface near the ground. The deflector is connected to the connector on the side away from the floor surface. The tensioning member is disposed on the deflector on the side away from the connector, and both ends of the tensioning member penetrate through the floor beams on both sides of the floor. The deflector deflects the tensioning member. The anchoring groove is opened in the floor beam and located on the side of the floor beam away from the deflector. The anchoring assembly is disposed at both ends of the tensioning member and located within the anchoring groove, thereby tightening the tensioning member.

[0006] Preferably, the anchoring groove is inclined and the height of the outer end opening is lower than the bottom height.

[0007] Preferably, the inclination angle of the anchoring groove is ten degrees.

[0008] Preferably, the connector is welded to the steering component.

[0009] Preferably, the end of the steering component that contacts the tensioning component is arc-shaped.

[0010] Preferably, the tensioning assembly further includes a first anchor bolt, which is connected to the connector and extends through the connector into the floor.

[0011] Preferably, the anchoring assembly includes a pad and an anchor. The pad is disposed in the anchoring groove, and the tensioning member passes through the pad. The anchor is disposed on the side of the pad away from the deflecting member, and the anchor is located in the anchoring groove to anchor the end of the tensioning member.

[0012] Preferably, the anchoring assembly further includes a second anchor bolt, which is connected to the pad and extends through the pad into the floor beam.

[0013] Preferably, the anchoring assembly further includes a seal that fills the anchoring groove.

[0014] Preferably, the material of the seal is polymer micro-expansion concrete.

[0015] Compared with the prior art, this utility model provides an external prestressed reinforcement structure, which has the following beneficial effects:

[0016] 1. This external prestressed reinforcement structure, by opening anchor grooves on the side of the floor beam away from the tensioning components, protects the anchors when anchoring the ends of the tensioning components. This prevents rain and snow from falling directly on the anchors, avoiding direct contact between the anchors and rain / snow, which could lead to rust, affect the anchoring effect, reduce the lifespan of the reinforced structure, and pose safety hazards. Furthermore, it prevents the formation of protruding bumps, ensuring the aesthetics of the building.

[0017] 2. This external prestressed reinforcement structure, by setting an anchoring groove with an outer end opening height lower than the bottom height, makes the overall opening direction of the anchoring groove tilted downward, ensuring that rain and snow will not come into contact with the anchor during rainy or snowy weather, thereby further ensuring the service life of the anchor.

[0024] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0025] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0026] Reference Figure 1 Figure 3 Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This utility model Figure 1 Enlarged schematic diagram of the structure at point A in the middle; Figure 3 This is a schematic diagram of the anchoring component structure of this utility model. An external prestressed reinforcement structure includes: a tensioning component 1, an anchoring groove 2, and an anchoring component 3. The tensioning component 1 includes a connector 11, a deflector 12, and a tensioning component 13. The connector 11 is located on the floor surface near the ground. The deflector 12 is connected to the connector 11 on the side away from the floor surface. The tensioning component 13 is located on the side of the deflector 12 away from the connector 11, and both ends of the tensioning component 13 penetrate through the floor beams on both sides of the floor. The deflector 12 deflects the tensioning component 13. The anchoring groove 2 is opened in the floor beam and is located on the side of the floor beam away from the deflector 12. The anchoring component 3 is located at both ends of the tensioning component 13 and is located in the anchoring groove 2. It tightens the tensioning component 13, and both ends of the tensioning component 13 are higher than the bottom of the deflector 12, ensuring that after the tensioning component 13 is tightened, it can apply an upward force to the deflector 12, thereby improving the load-bearing capacity of the floor.

[0027] Preferably, the connector 11 is disposed on the secondary beam at the bottom of the floor, so that the prestressed reinforcement structure can support multiple secondary beams of the floor, thereby reinforcing the floor and reducing the force required to be borne by the secondary beams and floor beams.

[0028] Preferably, multiple tension members 13 can be used to reinforce the same secondary beam, thereby further improving the reinforcement effect on the floor.

[0029] Preferably, when reinforcing a floor without secondary beams, an I-beam can be installed between the connector 11 and the floor to replace the secondary beam and reinforce the floor.

[0030] Tensioning member 13 is an unbonded steel strand, and after the floor reinforcement is completed, it is divided into a support section flush with the floor and a tensioning section inclined at a certain angle.

[0031] Preferably, the diameter of the anchoring groove 2 is 100 mm and the depth is 80 mm, and the side of the anchoring groove 2 away from the opening is perpendicular to the support section of the tensioning member 13.

[0032] This external prestressed reinforcement structure features anchor grooves on the side of the floor beam furthest from the tensioning components. These grooves protect the anchors during anchoring of the tensioning components, preventing rain and snow from directly contacting them and causing rust, which could affect the anchoring effect, reduce the lifespan of the reinforced structure, and create safety hazards. Furthermore, it prevents the formation of protruding bumps, ensuring the building's aesthetic appeal.

[0033] Rereference Figure 2 The anchoring groove 2 is opened at an angle, and the height of the outer end opening is lower than the bottom height.

[0034] Preferably, the inclination angle of the anchoring groove 2 is ten degrees. This angle is the preferred angle of the anchoring groove 2, which ensures the protective capability of the anchoring groove 2 for the anchoring component 3, and at the same time facilitates the installation of the anchoring component 3, reducing the installation difficulty of the anchoring component 3.

[0035] This external prestressed reinforcement structure, by setting an anchoring groove with an outer opening height lower than the bottom height, ensures that the overall opening direction of the anchoring groove is tilted downwards, thus preventing rain and snow from contacting the anchor during rainy or snowy weather, thereby further ensuring the service life of the anchor.

[0036] Specifically, the connector 11 is welded to the steering component 12, thereby connecting the connector 11 and the steering component 12 into one unit, so that there will be no displacement during the process of reinforcing the floor, which would prevent the floor from being unable to be reinforced.

[0037] Preferably, the end of the steering member 12 that contacts the tensioning member 13 is arc-shaped, so that the tensioning member 13 can turn along the arc-shaped end of the steering member 12. This avoids the situation where other angled steering members 12 are used to reinforce the floor, resulting in a large pressure on a single point, which can easily lead to damage and affect the service life.

[0038] Rereference Figure 1 The tensioning assembly 1 also includes a first anchor bolt 14, which is connected to the connector 11 and extends through the connector 11 into the floor. By setting the first anchor bolt 14 to connect the connector 11 and the floor, it is further possible to avoid the situation where the deflector 12 and the connector 11 are misaligned when reinforcing the floor, which would prevent the floor from being reinforced.

[0039] Rereference Figure 1 and Figure 2 The anchoring assembly 3 includes a pad 31 and an anchor 32. The pad 31 is disposed in the anchoring groove 2, and the tensioning member 13 passes through the pad 31. The anchor 32 is disposed on the side of the pad 31 away from the turning member 12, and is located in the anchoring groove 2. The anchor 32 anchors the end of the tensioning member 13. By connecting the anchor 32 to the end of the tensioning member 13, the tensioning member 13 is tightened. By setting the pad 31, the contact area between the anchor 32 and the floor beam is increased, so as to avoid the floor beam or anchor 32 being subjected to excessive pressure when the prestressed reinforcement structure is used to reinforce the floor, which could lead to damage and affect the service life of the building.

[0040] The anchoring assembly 3 also includes a second anchor bolt 33, which is connected to the pad 31 and penetrates the pad 31 and extends into the floor beam. By setting the second anchor bolt 33, the pad 31 is fixed to the floor beam, thereby increasing the stability of the pad 31 and the anchor 32, and thus improving the stability of the prestressed reinforcement structure for floor reinforcement.

[0041] The anchoring assembly 3 also includes a seal 34, which is filled into the anchoring groove 2. This seal 34 can seal the anchoring groove 2 and restore the outer side of the anchoring groove 2 to a flat state, thereby ensuring the aesthetics of the floor beam and further preventing rain and snow from leaking into the anchoring groove 2, which could cause the anchor 32 and the pad 31 to rust and affect the service life of the prestressed reinforcement structure.

[0042] Preferably, the sealing element 34 is made of polymer micro-expansion concrete. The shrinkage compensation function of polymer micro-expansion improves the sealing effect, and its excellent crack resistance and impermeability prevent water seepage, which could affect the service life of the reinforced structure and the building.
