Description

Technical Field

[0001] The present application relates to the field of building pile foundations, and in particular to a reinforced concrete building pile foundation. Background Art

[0002] A deep foundation consisting of a pile and a pile cap connected to the top of the pile, or a single pile foundation connected by a column and a pile foundation, is referred to as a pile foundation. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation. If the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Building pile foundations are usually low cap pile foundations. Pile foundations are widely used in high-rise buildings.

[0003] When pouring pile foundation, a pile foundation pit is generally excavated at the location where the pile foundation is required, and then a pre-tied steel cage is placed in the pile foundation pit, and then concrete is poured into the pile foundation pit to form a reinforced concrete building pile foundation supported by the pile foundation. The structure of the steel cage used is generally to form a number of stirrups by forming a steel ring, and then fix a number of steel bars on the stirrups to form a cylindrical frame.

[0004] When using a cylindrical steel cage composed of stirrups and steel bars, the fixation between the steel bars and the stirrups is simple, and only the strength between them is used for support. In the case of heavy-loaded cast buildings, the strength may not be sufficient. Utility Model Content

[0005] The purpose of the present application is to solve the problem raised in the above-mentioned background technology that when using a cylindrical steel cage composed of stirrups and steel bars, the fixation between the steel bars and the stirrups is simple, and only the strength between them is used for support, which may not be sufficient for cast buildings with heavier loads. The present application provides a reinforced concrete building pile foundation.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A reinforced concrete building pile foundation comprises a plurality of steel bars, wherein the plurality of steel bars are distributed in a circular pattern, the plurality of steel bars are provided with a plurality of stirrups 1 which are evenly distributed in a straight line, the stirrups 1 are fixedly connected to the steel bars, the plurality of steel bars are provided with a plurality of stirrups 2 which are distributed in a straight line, the stirrups 2 are fixedly connected to the steel bars, the steel bars are provided with a plurality of staggered auxiliary reinforcement mechanisms, and the steel bars are provided with a connecting mechanism.

[0008] By adopting the above technical scheme, the auxiliary reinforcement mechanism is used to limit and reinforce the two symmetrical steel bars, and the two limited steel bars are used to support stirrups 1 and 2. Finally, the two adjacent auxiliary reinforcement mechanisms are connected by a connecting mechanism, and then the steel cage composed of the steel bars, stirrups 1, stirrups 2, auxiliary reinforcement mechanism and connecting mechanism is placed in the excavated pile foundation pit, thereby further enhancing the strength of the steel bars, stirrups 1 and stirrups 2 entering the pile foundation pit, and at the same time reducing the possibility of large displacement of the steel bars, stirrups 1 and stirrups 2 when pouring concrete.

[0009] Furthermore, the auxiliary reinforcement mechanism includes two reinforcement blocks symmetrically arranged on stirrup one, the reinforcement blocks are provided with reinforcement grooves, the reinforcement grooves correspond to the steel bars, an adjustment component is arranged between the two reinforcement blocks, and a clamping component is arranged on both of the two reinforcement blocks.

[0010] By adopting the above technical solution, two reinforcement blocks are placed on two symmetrical steel bars, and then the reinforcement grooves on the reinforcement blocks are clamped on the steel bars by using the adjustment components. When the reinforcement blocks are sent into the pile foundation pit, the clamping components are clamped on the inner wall of the pile foundation pit, thereby strengthening the strength of the steel cage and reducing the possibility of the steel cage moving due to pouring concrete when the steel cage is in the pile foundation pit.

[0011] Furthermore, the adjustment component includes two fixed blocks symmetrically arranged on stirrup 1, the two fixed blocks are fixedly connected to the corresponding reinforcement blocks, and an adjustment threaded rod is fixed on the two fixed blocks, and an adjustment threaded sleeve is threadedly connected between the two adjustment threaded rods.

[0012] By adopting the above technical solution, the adjusting threaded sleeve is rotated to allow the two adjusting threaded rods to drive the two reinforcement blocks to move, thereby making it convenient for the reinforcement grooves on the reinforcement blocks to be stuck on the steel bars.

[0013] Furthermore, the clamping assembly includes a rotating seat rotatably connected to the reinforcement block, a clamping block is fixed on the rotating seat, a spring sheet is arranged between the clamping block and the reinforcement block, the spring sheet is U-shaped, and both ends of the spring sheet are fixedly connected to the clamping block and the reinforcement block.

[0014] By adopting the above technical solution, when the assembled steel cage is sent into the pile foundation pit, the edge of the pile foundation pit contacts the clamping block, allowing the clamping block to squeeze the spring sheet. After completely entering the pile foundation pit, the clamping block is pushed open by the spring sheet, and then the clamping block is blocked by the blocking block, allowing the clamping block to tilt and contact the inner wall of the pile foundation pit, thereby reducing the possibility of the steel cage moving due to pouring concrete when the steel cage is in the pile foundation pit.

[0015] Furthermore, a blocking block is fixed to one end of the reinforcement block close to the rotating seat, and the blocking block corresponds to the rotating seat.

[0016] By adopting the above technical solution, when the clamping block is opened under the push of the spring sheet, the blocking block blocks the clamping block, thereby reducing the possibility of excessive opening of the clamping block under the push of the spring sheet.

[0017] Furthermore, a plurality of reinforcing nails are fixed to one end of the clamping block away from the rotating seat.

[0018] By adopting the above technical solution, when the clamping block tilts toward the edge of the pile foundation pit, the reinforcing nails on the clamping block abut against the edge of the pile foundation pit, thereby further enhancing the strength of the clamping block clamped on the edge of the pile foundation pit.

[0019] Furthermore, the connecting mechanism includes a connecting hook 1 arranged on the adjusting threaded sleeve, the connecting hook 1 abuts against the corresponding adjusting threaded sleeve, a connecting hook 2 is arranged on the connecting hook 1, the connecting hook 2 abuts against the adjacent adjusting threaded sleeve, and a tightening assembly is arranged between the connecting hook 1 and the connecting hook 2.

[0020] By adopting the above technical solution, the connecting hook 1 and the connecting hook 2 are respectively buckled on the adjacent adjusting threaded sleeves, and then the tightening assembly is used to restrict the adjacent adjusting threaded sleeves by the connecting hook 1 and the connecting hook 2, so as to further improve the stability of the reinforcement block stuck on the steel bar and further enhance the overall strength of the steel cage.

[0021] Furthermore, the tightening assembly includes a tightening sleeve ball-connected to the first connecting hook, a tightening threaded rod is threadedly connected to the tightening sleeve, and one end of the tightening threaded rod away from the tightening sleeve is ball-connected to the second connecting hook.

[0022] By adopting the above technical solution, the tightening sleeve is rotated to allow the tightening threaded tube to move on the tightening sleeve, thereby making it convenient to allow the connecting hook 1 and the connecting hook 2 to approach each other.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. The present application, after fixing the steel bars, stirrups 1 and 2, starts from the bottom, passes two reinforcement blocks through the adjacent stirrups 1, makes the reinforcement grooves on the two reinforcement blocks face the corresponding steel bars, and then rotates the adjusting threaded sleeve. When the adjusting threaded sleeve rotates, the two adjusting threaded rods move on the adjusting threaded sleeve, the two adjusting threaded rods approach each other and drive the fixed block, the fixed block drives the reinforcement block, makes the reinforcement groove on the reinforcement block stuck on the steel bar, uses the reinforcement block, the adjusting threaded rod, and the adjusting threaded sleeve to support the steel bar stuck in the reinforcement groove, makes the steel bar support stirrups 1 and 2, and then adds reinforcement blocks in sequence, and makes the reinforcement blocks staggered and stuck on different steel bars at the same time, so as to improve the strength of the entire steel cage, thereby achieving the purpose of strengthening the strength of the composed steel cage and improving the overall bearing capacity.

[0025] 2. In the present application, when the assembled steel cage is sent into the pile foundation pit, the edge of the pile foundation pit contacts the clamping block, allowing the clamping block to squeeze the spring sheet. When the steel cage completely enters the pile foundation pit, the clamping block is pushed open by the spring sheet, and then the clamping block is obliquely contacted with the inner wall of the pile foundation pit under the obstruction of the blocking block, thereby achieving the purpose of reducing the possibility of the steel cage moving due to pouring concrete when the steel cage is in the pile foundation pit.

[0026] 3. In the present application, after several reinforcement blocks are stuck on the steel bar, the first connecting hook is used to hook the adjusting threaded sleeve, and the second connecting hook is used to hook another adjacent adjusting threaded sleeve, and then the tightening sleeve is rotated to move the tightening threaded rod on the tightening sleeve, so that the first connecting hook and the second connecting hook are close to each other, and the first connecting hook and the second connecting hook restrict the adjacent adjusting threaded sleeves, thereby achieving the purpose of further improving the stability of the reinforcement blocks stuck on the steel bar and further enhancing the overall strength of the steel cage.

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The embodiment of the present application discloses a reinforced concrete building pile foundation.

[0034] Reference Figure 1 , Figure 2 and Figure 3 A reinforced concrete building pile foundation comprises a plurality of steel bars 1, the plurality of steel bars 1 are distributed in a circle, a plurality of stirrups 2 uniformly distributed in a straight line are arranged on the plurality of steel bars 1, the stirrups 2 are fixedly connected to the steel bars 1, a plurality of stirrups 3 distributed in a straight line are arranged on the plurality of steel bars 1, the stirrups 2 3 are fixedly connected to the steel bars 1, a plurality of staggered auxiliary reinforcement mechanisms 4 are arranged on the steel bars 1, and a connecting mechanism 5 is arranged on the steel bars 1.

[0035] When pouring the building pile foundation, first take out a stirrup 1 2, then evenly fix a number of circumferentially distributed steel bars 1 on the stirrup 1 2, then evenly fix the stirrup 1 2 on the steel bar 1, then evenly fix the evenly distributed stirrup 2 3 on the circumferentially distributed steel bar 1, then pass the auxiliary reinforcement mechanism 4 between the adjacent stirrups 1 2, let the auxiliary reinforcement mechanism 4 limit and reinforce the two symmetrical steel bars 1, let the two limited steel bars 1 support the stirrup 1 2 and the stirrup 2 3, and finally use the connecting mechanism 5 to connect the two adjacent auxiliary reinforcement mechanisms 4. Then, the steel cage consisting of the steel bar 1, stirrup 1 2, stirrup 2 3, auxiliary reinforcement mechanism 4 and connecting mechanism 5 is placed in the excavated pile foundation pit, and then concrete is poured to form a completed building pile foundation. The symmetrical steel bars 1 are restricted and supported by the auxiliary reinforcement mechanism 4 on the steel bar 1, and then the inner wall of the pile foundation pit is clamped by the auxiliary reinforcement mechanism 4, so as to further enhance the strength of the steel bar 1, stirrup 1 2 and stirrup 2 3 entering the pile foundation pit, and at the same time reduce the possibility of large deviation of the steel bar 1, stirrup 1 2 and stirrup 2 3 when pouring concrete.

[0036] Reference Figure 1 , Figure 2 and Figure 3 The auxiliary reinforcement mechanism 4 includes two reinforcement blocks 41 symmetrically arranged on the stirrup 2, and a reinforcement groove 42 is opened on the reinforcement block 41, and the reinforcement groove 42 corresponds to the steel bar 1. An adjustment component 43 is arranged between the two reinforcement blocks 41, and a clamping component 44 is arranged on both reinforcement blocks 41.

[0037] In addition, the adjustment component 43 includes two fixed blocks 431 symmetrically arranged on the stirrup 2, the two fixed blocks 431 are fixedly connected to the corresponding reinforcement blocks 41, and the two fixed blocks 431 are fixed with adjustment threaded rods 432, and the two adjustment threaded rods 432 are threadedly connected with an adjustment threaded sleeve 433.

[0038] In addition, the clamping assembly 44 includes a rotating seat 442 rotatably connected to the reinforcement block 41, and a clamping block 441 is fixed on the rotating seat 442. A spring sheet 443 is arranged between the clamping block 441 and the reinforcement block 41. The spring sheet 443 is U-shaped, and both ends of the spring sheet 443 are fixedly connected to the clamping block 441 and the reinforcement block 41.

[0039] Furthermore, a blocking block 444 is fixed to one end of the reinforcing block 41 close to the rotating seat 442 , and the blocking block 444 corresponds to the rotating seat 442 .

[0040] After the steel bar 1, stirrup 1 2 and stirrup 2 3 are fixed, starting from the bottom, the two reinforcement blocks 41 are passed through the adjacent stirrups 1 2, so that the reinforcement grooves 42 on the two reinforcement blocks 41 face the corresponding steel bar 1, and then the adjusting threaded sleeve 433 is rotated. When the adjusting threaded sleeve 433 is rotated, the two adjusting threaded rods 432 move on the adjusting threaded sleeve 433, and the two adjusting threaded rods 432 approach each other and drive the fixed block 431. The fixed block 431 drives the reinforcement block 41, so that the reinforcement groove 42 on the reinforcement block 41 is stuck on the steel bar 1, and the reinforcement block 41, the adjusting threaded rod 432, and the adjusting threaded sleeve 433 are used together to support the steel bar 1 stuck in the reinforcement groove 42, so that the steel bar 1 supports the stirrups 1 2 and stirrups 2 3, and then the fixing blocks 41 are added in sequence, and at the same time, the reinforcement blocks 41 are staggered and stuck on different steel bars 1 to improve the strength of the entire steel cage. When the cage is sent into the pile foundation pit, the edge of the pile foundation pit contacts the clamping block 441, allowing the clamping block 441 to squeeze the spring sheet 443. After completely entering the pile foundation pit, the clamping block 441 is opened under the push of the spring sheet 443, and then the clamping block 441 is obliquely pressed against the inner wall of the pile foundation pit under the blockage of the blocking block 444. When pouring concrete, when the entire steel cage is pushed by the concrete, the clamping block 441 is clamped on the edge of the pile foundation pit, so that the entire steel bar will not move upward due to the pouring of concrete. By using the reinforcement block 41 to clamp two symmetrical steel bars 1, and then supporting the two steel bars 1, the two steel bars 1 support the stirrups 1 2 and stirrups 2 3, and at the same time allowing the clamping block 441 to be clamped on the inner wall of the pile foundation pit, the strength of the steel cage can be strengthened, and at the same time, the possibility of the steel cage moving due to pouring concrete when the steel cage is in the pile foundation pit can be reduced.

[0041] Reference Figure 1 , Figure 2 and Figure 3 A plurality of reinforcing nails 445 are fixed to one end of the clamping block 441 away from the rotating seat 442. When the clamping block 441 tilts toward the edge of the pile foundation pit, the reinforcing nails 445 on the clamping block 441 abut against the edge of the pile foundation pit, and then the reinforcing nails 445 penetrate into the edge of the pile foundation pit. By allowing the reinforcing nails 445 on the clamping block 441 to penetrate into the edge of the pile foundation pit, the strength of the clamping block 441 clamped on the edge of the pile foundation pit can be further enhanced.

[0042] Reference Figure 1 and Figure 2 The connecting mechanism 5 includes a connecting hook 51 arranged on the adjusting threaded sleeve 433, the connecting hook 51 abuts against the corresponding adjusting threaded sleeve 433, a connecting hook 2 52 is arranged on the connecting hook 51, the connecting hook 2 52 abuts against the adjacent adjusting threaded sleeve 433, and a tightening assembly 53 is arranged between the connecting hook 51 and the connecting hook 2 52.

[0043] In addition, the tightening assembly 53 includes a tightening sleeve 532 ball-jointed on the connecting hook 1 51 , a tightening threaded rod 531 is threadedly connected to the tightening sleeve 532 , and one end of the tightening threaded rod 531 away from the tightening sleeve 532 is ball-jointed with the connecting hook 2 52 .

[0044] After several reinforcement blocks 41 are stuck on the steel bar 1, use the connecting hook 1 51 to hook the adjusting threaded sleeve 433, and then let the connecting hook 2 52 hook another adjacent adjusting threaded sleeve 433, and then rotate the tightening sleeve 532 to move the tightening threaded tube on the tightening sleeve 532, so that the connecting hook 1 51 and the connecting hook 2 52 are close to each other, and the connecting hook 1 51 and the connecting hook 2 52 restrict the adjacent adjusting threaded sleeves 433. By using the connecting hook 1 51 and the connecting hook 2 52 to restrict the adjacent adjusting threaded sleeves 433, the stability of the reinforcement block 41 stuck on the steel bar 1 can be further improved, and the overall strength of the steel cage can be further enhanced.

[0045] Working principle: When pouring the pile foundation of a building, first take out a stirrup 1 2, then evenly fix a number of circumferentially distributed steel bars 1 on the stirrup 1 2, then evenly fix the stirrup 1 2 on the steel bar 1, and then evenly fix the stirrup 2 3 on the circumferentially distributed steel bar 1. After the steel bar 1, stirrup 1 2 and stirrup 2 3 are all fixed, start from the bottom and pass two reinforcement blocks 41 between adjacent stirrups 1 2, so that the reinforcement grooves 42 on the two reinforcement blocks 41 face the corresponding steel bar 1, and then rotate the adjustment threaded sleeve 433. When adjusting the threaded sleeve 433, When rotating, the two adjusting threaded rods 432 move on the adjusting threaded sleeve 433, and the two adjusting threaded rods 432 approach each other and drive the fixed block 431, and the fixed block 431 drives the reinforcement block 41, so that the reinforcement groove 42 on the reinforcement block 41 is stuck on the steel bar 1, and the reinforcement block 41, the adjusting threaded rod 432, and the adjusting threaded sleeve 433 are used together to support the steel bar 1 stuck in the reinforcement groove 42, so that the steel bar 1 supports the stirrup 1 2 and the stirrup 2 3, and then the fixing blocks 41 are added in sequence, and at the same time, the reinforcement blocks 41 are staggered and stuck on different steel bars 1 to improve the strength of the entire steel cage.

[0046] After several reinforcement blocks 41 are stuck on the steel bar 1, the connecting hook 1 51 is used to hook the adjusting threaded sleeve 433, and then the connecting hook 2 52 is used to hook another adjacent adjusting threaded sleeve 433, and then the tightening sleeve 532 is rotated to move the tightening threaded pipe on the tightening sleeve 532, so that the connecting hook 1 51 and the connecting hook 2 52 are close to each other, and the connecting hook 1 51 and the connecting hook 2 52 restrict the adjacent adjusting threaded sleeve 433, and then the assembled steel cage is sent into the pile foundation pit. When the pile foundation pit is in the middle, the edge of the pile foundation pit contacts the clamping block 441, allowing the clamping block 441 to squeeze the spring sheet 443. After completely entering the pile foundation pit, the clamping block 441 is opened under the push of the spring sheet 443, and then the clamping block 441 is obliquely contacted against the inner wall of the pile foundation pit under the blocking of the blocking block 444. When pouring concrete, when the entire steel cage is pushed by the concrete, the clamping block 441 is stuck on the edge of the pile foundation pit, the concrete pouring is completed, and the pile foundation construction is completed.
