Description

Technical Field

[0001] The utility model relates to the technical field of cast-in-place piles, and particularly relates to an anti-floating steel reinforcement cage. Background Art

[0002] During the construction of cast-in-place concrete piles, the force on the steel reinforcement cage is the resultant force of the floating friction generated by the upward movement of the slurry and concrete mixture, the friction with the concrete buried at the lower part, the self-weight of the steel reinforcement cage, and the pressure generated by the fixation of the steel reinforcement cage. If the floating force exceeds the downward force, the steel reinforcement cage will float upward, directly affecting the construction quality of the bored cast-in-place pile. For example, the Chinese utility model patent with the application number 202322814370.6 discloses a steel reinforcement cage structure that can effectively prevent the sediment in the rotary drilling pile from falling into the hole. The steel reinforcement cage structure is placed in the pile hole and includes a steel reinforcement cage, stirrups, waterproof cloth, and steel wire ropes. The stirrups are spirally arranged on the steel reinforcement cage from bottom to top; the waterproof cloth wraps the outside of the steel reinforcement cage; the steel wire ropes are spirally wound around the steel reinforcement cage from bottom to top and are placed outside the waterproof cloth. This kind of steel reinforcement cage has a small self-weight, poor anti-floating effect, and is a hollow structure, so it is easy to deform and has poor structural stability. Summary of the Invention

[0003] In view of the deficiencies of the background art, the technical problem to be solved by the utility model is to provide an anti-floating steel reinforcement cage with better anti-floating effect and stable and firm structure.

[0004] To this end, the utility model is implemented by adopting the following technical solutions:

[0005] An anti-floating steel reinforcement cage includes a number of vertical bars distributed circumferentially. The outer circles of the vertical bars are connected and fixed by multiple stirrups from top to bottom. The feature is that each stirrup is provided with at least one transverse support and a longitudinal support. The intersection of the transverse support and the longitudinal support is fixedly connected, and the transverse support and the longitudinal support are fixedly connected to the upper end or the lower end of the stirrup.

[0006] Further, both the inner end faces of the transverse support and the longitudinal support are provided with bidirectional open chutes along their lengths. Anchor rods that can be inserted into the soil around the steel reinforcement cage are arranged in the bidirectional open chutes.

[0007] Further, racks are slidably arranged in the bidirectional open chutes. The anchor rods are arranged at the side ends of the racks. The steel reinforcement cage is equipped with an operating rod. A plurality of gears meshing with the corresponding racks are arranged on the operating rod, and a handwheel is arranged at the upper end of the operating rod.

[0008] Further, each stirrup is equipped with two transverse supports and longitudinal supports. The racks of the two transverse supports mesh with one gear on the operating rod, and the racks of the two longitudinal supports mesh with one gear.

[0009] Furthermore, bases are provided at the lower ends of the two lowermost longitudinal supports, and positioning holes for inserting the operating rods are provided on the bases.

[0010] Furthermore, the handwheel and the uppermost stirrup are detachably connected by multiple ropes, and multiple opposite jacks are provided on the handwheel.

[0011] Furthermore, the cross-section of the double-sided open chute is trapezoidal.

[0012] Furthermore, the stirrups and the vertical bars are fixed by welding, the cross-over part of the transverse supports and the longitudinal supports is fixed by welding, and the transverse supports, the longitudinal supports and the stirrups are fixed by welding.

[0013] After adopting the above technical solution, each stirrup is provided with at least one transverse support and one longitudinal support, and the cross-over part of the transverse support and the longitudinal support is fixedly connected, which not only increases the overall weight of the steel reinforcement cage, enhances the anti-floating effect of the steel reinforcement cage, but also makes the overall structure of the steel reinforcement cage more firm and stable, effectively avoiding deformation caused by collision during the transportation and lowering processes of the steel reinforcement cage.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following, in conjunction with the drawings and preferred embodiments, details the specific embodiments, structures, features and their effects of the present utility model as follows.

[0022] As shown in the above-mentioned drawings, a floating-resistant steel reinforcement cage provided by the utility model comprises a number of vertical bars 1 distributed circumferentially. The outer circles of the number of vertical bars 1 are connected and fixed by a plurality of stirrups 2 from top to bottom. Its characteristics are: each of the stirrups 2 is provided with at least one transverse support 3 and a longitudinal support 4. The cross-over part of the transverse support 3 and the longitudinal support 4 is fixedly connected, and the transverse support 3 and the longitudinal support 4 are fixedly connected to the upper end or the lower end of the stirrup 2. The inner end faces of the transverse support 3 and the longitudinal support 4 are provided with double-open chutes 5 along their lengths. Anchor rods 6 that can be inserted into the soil mass 15 around the steel reinforcement cage are arranged in the double-open chutes 5. A rack 7 is slidably arranged in the double-open chutes 5. The anchor rod 6 is arranged at the side end of the rack 7. The steel reinforcement cage is equipped with an operating rod 8. A plurality of gears 9 meshing with the corresponding racks 7 are arranged on the operating rod 8. A handwheel 10 is arranged at the upper end of the operating rod 8. Each of the stirrups 2 is equipped with two transverse supports 3 and longitudinal supports 4. The racks 7 of the two transverse supports 3 are meshed with one gear 9 on the operating rod 8. The racks 7 of the two longitudinal supports 4 are meshed with one gear 9. The lower ends of the two lowermost longitudinal supports 4 are provided with a base 11. The base 11 is provided with a positioning hole 12 for inserting the operating rod 8. The handwheel 10 and the uppermost stirrup 2 are detachably connected by a plurality of ropes 13. A plurality of opposite jacks 14 are arranged on the handwheel 10. The cross-section of the double-open chute 5 is trapezoidal. The stirrup 2 and the vertical bar 1 are fixedly connected by welding. The cross-over part of the transverse support 3 and the longitudinal support 4 is fixedly connected by welding. The transverse support 3, the longitudinal support 4 and the stirrup 2 are fixedly connected by welding.

[0023] The working principle of the utility model is as follows:

[0024] When the steel reinforcement cage is produced, the operating rod 8 is inserted into the positioning hole 12 of the base 11, and each gear 9 is meshed with the corresponding rack 7. Finally, the handwheel 10 and the stirrup 2 are tied together by the rope 13 to complete the limit of the operating rod 8 and prevent the gear 9 and the rack 7 from loosening. After the steel reinforcement cage is lowered, the rope 13 is untied and the handwheel 10 is rotated counterclockwise, driving the operation and the gear 9 to rotate counterclockwise. The gear 9 drives the rack 7 to slide in the double-open chute 5, so that the anchor rod 6 is inserted into the soil mass 15 around the steel reinforcement cage, making the steel reinforcement cage and the surrounding soil mass 15 integrated into one body, effectively preventing the steel reinforcement cage from floating, having a better anti-floating effect and a more stable structure. Finally, the handwheel 10 is lifted to take out the operating rod 8, and the operating rod 8 can be reused, saving costs.

[0025] In this embodiment, each stirrup 2 is provided with at least one transverse support 3 and a longitudinal support 4, and the cross - connected part of the transverse support 3 and the longitudinal support 4 is fixedly connected, which not only increases the overall weight of the steel reinforcement cage, enhances the anti - floating effect of the steel reinforcement cage, but also makes the overall structure of the steel reinforcement cage more firm and stable, effectively avoiding deformation caused by collision during the transportation and lowering process of the steel reinforcement cage; when the diameter of the steel reinforcement cage is too large or the soil is too hard and the handwheel 10 is not easy to operate, a long rod can be inserted through the jack 14 of the handwheel 10 for the convenience of the staff to operate; the cross - section of the double - open chute 5 is trapezoidal to prevent the rack 7 from disengaging.

[0026] The above is only a preferred embodiment of the present invention, and it is not intended to limit the present invention in any form. Although the present invention has been disclosed as above with a preferred embodiment, it is not used to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
