For the purpose of illustration, the drawings show only the structures associated with embodiments of the utility model.
Referring to fig. 1, in the actual construction process, the prestressed anti-floating anchor rod 100 is used to enhance the anti-floating bearing capacity of the basement floor 200. The prestressed anti-floating anchor 100 includes a rod body 10 and a prestressed anti-floating anchor reinforcing structure 20 disposed on the rod body 10.
Specifically, the first axial end of the rod body 10 is poured into the cast-in-place layer of the basement bottom plate 200, and the second axial end of the rod body 10 is poured before the basement bottom plate 200 is poured, and applies a pre-stress together with the first axial end to make the rod body 10 become a rigid rod member with an internal pressure, and the rigid rod member is embedded in the basement bottom plate 200 and the foundation below the basement bottom plate. The basement bottom plate 200 is stably connected with the foundation by the friction force between the rod body 10 and the cast-in-place layer of the basement bottom plate 200 and the foundation respectively, so that the basement bottom plate 200 is prevented from being separated from the foundation when being subjected to upward buoyancy.
Referring to fig. 2, 3 and 4, in some embodiments, the pre-stressed anti-floating anchor reinforcement structure 20 includes an anchor assembly 21. The anchoring assembly 21 includes a connecting member 211 and an anchoring member 212, wherein the connecting member 211 is fixed to the first axial end of the main body 10 and extends along the longitudinal direction of the main body 10 toward the side away from the main body 10. The anchoring member 212 is disposed on the connecting member 211 and is disposed at an angle with respect to the longitudinal direction of the connecting member 211. In addition, the connecting member 211 and the anchoring member 212 are anchored in the cast-in-place layer of the basement floor 200. Specifically, by providing the anchor 212, the contact area of the prestressed anti-floating anchor 100 with the concrete in the basement floor 200 can be increased. Also, since the anchor 212 is disposed at an angle to the longitudinal direction of the coupling member 211, that is, the anchor 212 is disposed at an angle to the longitudinal direction of the rod body 10. Therefore, the rod body 10 can be further prevented from being pulled away from the basement floor 200 due to the upward pulling force generated in the longitudinal direction of the rod body, and the anchoring strength of the prestressed anti-floating anchor 100 is ensured.
Further, the first end of the rod body 10 is used for anchoring with the basement floor 200, and the second end is used for connecting the foundation, thereby stably connecting the basement floor 200 with the foundation. The friction between the prestressed anti-floating anchor 100 and the basement floor 200 is enhanced by the anchoring assembly 21, so that the prestressed anti-floating anchor 100 has a larger holding force on the basement floor 200. When basement bottom plate 200 receives ascending buoyancy effect, because the connection between prestressing force anti-floating stock 100 and basement bottom plate 200 is more firm, can prevent that basement bottom plate 200 from separating with prestressing force anti-floating stock 100 to avoid prestressing force anti-floating stock 100 to be pulled off from basement bottom plate 200. Thereby, the connection between the basement floor 200 and the foundation can be made more stable.
Specifically, the first end of the rod body 10 is disposed in the basement bottom plate 200, and the second end is pre-embedded in the foundation under the basement bottom plate 200, and concrete is poured into the basement bottom plate 200. When the basement bottom plate 200 is acted by buoyancy, the anchoring component 21 floats upwards along with the basement bottom plate 200, however, because the rod body 10 is pre-buried in the foundation, the friction force between the rod body 10 and the foundation overcomes the upward buoyancy generated by the influence of the underground water on the anchoring component 21 and the basement bottom plate 200. However, if the bond force between the anchor assembly 21 and the basement floor 200 is insufficient, the basement floor 200 will separate from the prestressed anti-floating anchor 100 under the action of the buoyancy, so that the prestressed anti-floating anchor 100 cannot enhance the anti-floating capability of the basement floor 200. From this, through setting up anchor assembly 21, strengthened the bond stress between prestressing force anti-floating stock 100 and the basement bottom plate 200 for connection between them is more firm, has strengthened the anti floating ability of basement bottom plate 200 through pole body 10.
In some embodiments, the prestressed anti-floating anchor reinforcing structure 20 includes a backing plate 22, the backing plate 22 is fixed to the first end of the rod body 10 in a horizontal direction, and the connecting member 211 is vertically fixed to the backing plate 22. Among them, the anchor 212 is a peg provided on the connection member 211. The backing plate 22 can provide a mounting base for the anchor assembly 21, making the connection of the anchor assembly 21 to the rod body 10 more secure.
Further, the connection member 211 is fixedly connected to the backing plate 22 by welding, so that the connection between the connection member 211 and the backing plate 22 can be more firmly made.
In the present embodiment, the connection member 211 is configured as a square steel pipe, and the stud is provided at a side of the square steel pipe. One end of the square steel pipe is fixed to the backing plate 22, and the square steel pipe is extended toward the side away from the rod body 10 along the longitudinal direction of the rod body 10. The side surfaces of the stud and the square steel tube are arranged at a certain angle, and the side surfaces of the square steel tube are a plane, so that the connection between the stud and the square steel tube can be more stable. It is understood that in other embodiments, the connecting member 211 may also be a steel pipe with other structures, which are not described herein.
In some embodiments, the anchors 212 include a plurality and are uniformly arranged along the circumference of the connection member 211. In the present embodiment, the peg includes a plurality of pegs, and is uniformly arranged along the axial direction of the connecting member 211. The studs are uniformly arranged on the periphery of the connecting piece 211, so that the stress of the connecting piece 211 is more uniform, and the arrangement of the connecting piece in the basement bottom plate 200 is more stable.
In the present embodiment, the connecting member 211 is a square steel tube, and therefore, the studs are uniformly arranged on the circumferential side of the square steel tube. Further, the square steel pipe includes four sides of interconnect, and the peg includes twelve, has evenly arranged three pegs on each side, and three pegs set up along the lengthwise direction interval of square steel pipe. In practical use, the diameter of the peg is 16mm, and the shear resistance design value of a single peg can adopt the formula fv multiplied by AsThe design value of the shear resistance of the single stud is calculated to be 305x4770 and 1450 kN. The design value of the tension of each prestressed anti-floating anchor rod 100 is 400kN, so that twelve studs can effectively resist prestressThe tension of the anti-floating anchor rod 100 ensures the anchoring strength of the pre-stressed anti-floating anchor rod 100. In addition, three pegs are evenly arranged on each side of the square steel pipe, so that the stress on each side of the square steel pipe is even, and the prestressed anti-floating anchor rod 100 is more stable in the basement bottom plate 200.
Further, the anchor 212 is disposed to extend in a direction perpendicular to the lengthwise direction of the link 211. Specifically, the stud is extended along the longitudinal direction perpendicular to the square steel tube and is disposed on the side surface thereof, so that the prestressed anti-floating anchor rod 100 can obtain a larger friction force in the pulling direction, and the prestressed anti-floating anchor rod 100 is more stably disposed in the basement floor 200.
In the embodiment, the anchor 212 is fixedly connected to the connecting member 211 by welding. Namely, the stud and the square steel tube are connected by welding. Adopt welded connected mode, can make the connection between stud and the square steel pipe more firm.
Based on the same concept as the above-described pre-stressed anti-floating anchor reinforcing structure 20, the present invention also provides a pre-stressed anti-floating anchor 100, the pre-stressed anti-floating anchor 100 including the pre-stressed anti-floating anchor reinforcing structure 20 as described above.
In some embodiments, the pre-stressed anti-floating anchor 100 further includes an anchor set 30, the anchor set 30 being disposed at a first end and abutting against the pre-stressed anti-floating anchor reinforcement structure 20 facing away from the first end to provide a pre-stress for anchoring the pre-stressed anti-floating anchor 100 in the basement floor 200. In the present embodiment, the die set 30 is a clip-type die set, and is abutted against the backing plate 22 in a direction away from the first end. The clip die set is tensioned and, after tensioning, the clip die set rests on the backing plate 22 under the retracting action of the clips. When the anti-floating anchor rod 100 of prestressing force is pre-buried in ground and basement bottom plate 200, because the clamp piece formula mould group exerts pressure to backing plate 22 for anti-floating anchor rod 100 of prestressing force forms the internal pressure, when basement bottom plate 200 receives the buoyancy effect come-up to form the pulling force to rod body 10, rod body 10 can not the fracture, thereby satisfies corresponding standard's requirement.
In addition, for the prestressed anti-floating anchor rod 100, after the die set 30 is tensioned and tightened, the pre-pressure of the prestressed anti-floating anchor rod 100 is related to the compression amount of the force transmission part under the tightening anchor ring, the larger the compression value is, the smaller the effective pre-pressure is, when the pre-pressure is insufficient, the rod body 10 will crack when the tension generated by the buoyancy of the water transferred from the basement bottom plate 200 exceeds the pre-pressure, that is, the requirement of the above specification is not met, and the anti-floating of the basement bottom plate 200 is disabled. However, in this particular embodiment, by securing anchor assembly 21 to backing plate 22 only, the compression value of anchor set 30 is not increased upon tightening of the anchor rings of die set 30. Therefore, the compression amount of the die set 30 is smaller when the die set applies pressure to the base plate 22, and the requirement of the finished product anchor compression limit value is completely met, so that the prestress can be effectively prevented from cracking under the action of the water buoyancy force transmitted by the basement bottom plate 200 of the prestress anti-floating anchor rod 100, namely, the requirement of the specification is met, and the anti-floating capacity of the basement bottom plate 200 is enhanced.
When the prestressed anti-floating anchor rod is used, firstly, a hole forming machine is used for drilling a hole in a foundation, then the prestressed anti-floating anchor rod and the prestressed reinforcement are placed in the drilled hole through measures such as arranging a bracket and the like, and then construction is carried out according to the conventional construction method of the prestressed anti-floating anchor rod.
After the pre-stressed anti-floating anchor rod 100 reaches the design strength, the pre-stressed steel bars arranged in the rod body 10 are tensioned at the first end, and the die set 30 is pressed against the backing plate 22, so that the pre-stressed anti-floating anchor rod 100 which is embedded in the foundation and has internal pressure is manufactured. Thereafter, reinforcing bars are laid in the basement floor 200 and embedded in the thickness of the basement floor 200 together with the pre-stressed anti-floating anchor reinforcement structure 20 and the mold set 30. After the concrete in the basement bottom plate 200 is poured, the anchor rod body 10, the prestressed anti-floating anchor rod reinforcing structure 20 and the mold set 30 form an anti-floating structural whole with the basement bottom plate 200.
When the basement bottom plate 200 is acted by the upward floating force, the prestressed anti-floating anchor rod 100 can transmit the pulling force to the foundation through the firm bond of the prestressed anti-floating anchor rod reinforcing structure 20 and the basement bottom plate 200. The binding force is generated between the studs and the square steel pipe and the concrete 200, so that the basement bottom plate 200 is tightly connected with the prestressed anti-floating anchor rod 100, and the separation of the basement bottom plate 200 and the prestressed anti-floating anchor rod 100 under the action of buoyancy is avoided. Further, a frictional force is generated between the rod body 10 and the foundation, so that the prestressed anti-floating anchor rod 100 is stabilized in the foundation. Therefore, under the connection of the prestressed anti-floating anchor rod 100, the basement bottom plate 200 is closely attached to the foundation, and the anti-floating capacity of the basement bottom plate 200 is improved.
The prestressed anti-floating anchor rod reinforcing structure 20 and the prestressed anti-floating anchor rod 100 in the above embodiments have at least the following advantages:
1) the contact area between the prestressed anti-floating anchor rod 100 and the concrete can be increased by the studs and the square steel pipes, and the bond stress between the prestressed anti-floating anchor rod 100 and the concrete is increased, so that the connection between the basement floor 200 and the prestressed anti-floating anchor rod 100 is more stable, and the separation of the basement floor 200 from the prestressed anti-floating anchor rod 100 under the action of buoyancy is prevented;
2) the studs are evenly distributed on the sides of the square steel pipe along the circumferential direction of the square steel pipe, so that the stress of the square steel pipe is more even, and the prestressed anti-floating anchor rod 100 is more stable in the basement floor 200.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
