Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to an installation structure for reinforcing bar suspension bars in bored cast-in-place piles. Background Technology

[0002] With the development of construction engineering technology, bored cast-in-place piles have become a commonly used type of pile foundation and slope reinforcement in the construction industry. The quality of the cast-in-place piles is a crucial factor determining the safety and stability of the superstructure and slope. Construction quality is extremely important for the quality of bored cast-in-place piles, and the control of the reinforcing cage is a critical quality control point. Both the hoisting of the reinforcing cage and the pouring of concrete are carried out on the ground. After the reinforcing cage is installed, according to relevant requirements, the bottom of the reinforcing cage should be approximately 100-200mm from the bottom of the pile hole. Concrete is poured into the reinforcing cage using the tremie pipe method. As the concrete rises, the reinforcing cage experiences buoyancy due to the concrete, causing it to float. This can lead to quality problems such as displacement of the reinforcing cage and the main reinforcement exceeding the designed pile top elevation.

[0003] Common anti-buoyancy measures for pile foundation reinforcement cages generally employ two or more steel bars or rigid materials as uprights. The upper end of the upright is fixed and locked to the inner wall of the steel casing or clamped into the grid on both sides of the flange frame of the grouting platform. The other end of the upright is locked to the top hoop of the reinforcement cage via a fork or clip. Fixing the upper end of the upright to the outside environment prevents the reinforcement cage from floating. Another anti-buoyancy measure for pile foundation reinforcement cages is to weld steel pipes inside the reinforcement cage and press down on the steel pipes to prevent the reinforcement cage from floating.

[0004] However, because the steel pipes are welded and fixed to the reinforcing cage, they can only be used for one cage at a time. When constructing other cages, the corresponding steel pipes must be re-welded to prevent them from floating during concrete pouring. This method requires workers to weld the steel pipes multiple times, resulting in a large workload. Furthermore, the welded steel pipes are difficult to reuse, leading to high processing costs. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides an installation structure for reinforcing bar suspension bars in bored cast-in-place piles, thereby solving the technical problems of large workload and high processing costs in the construction of anti-floating reinforcing bar cages.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: An installation structure for reinforcing bars in bored piles includes a sinking component and a closing rope. The sinking component is divided into an upper pressure-applying part and a lower clamping part. The clamping part has an opening on one side; both sides of the opening on the clamping part have through holes for rope threading. The end of the closing rope can pass through or be withdrawn from the through holes, thereby closing or opening the opening of the clamping part.

[0007] Furthermore, one end of the sealing rope passes through two rope holes in sequence to close the opening of the clamp. The end of the sealing rope after passing through the two rope holes is folded back upwards and tied to the other end of the sealing rope to form a closed loop structure.

[0008] Furthermore, the clamp part has a C-shaped structure. Two rope holes are respectively opened at both ends of the clamp part.

[0009] Furthermore, the clamp portion consists of a middle connecting section and two end clamping sections. The two end clamping sections are parallel to each other. Two rope holes are respectively opened at the outer ends of the clamping sections.

[0010] Furthermore, a hook is fixed to the top of the pressure-applying part.

[0011] Furthermore, there are two sinking components, which are symmetrically installed on both sides of the steel cage, and each has a sealing rope at its bottom.

[0012] Furthermore, the steel reinforcement cage has a cylindrical structure, including multiple main bars and multiple stirrups. The main bars are parallel to each other and arranged in a circumferential array to form the main body of the cage. The stirrups are fixed to the main body of the cage in sequence at intervals; the stirrups extend into the openings of the clamping parts in the sinker.

[0013] Furthermore, the stirrups are spiral stirrups.

[0014] Compared with the prior art, the present invention has the following advantages: This invention achieves rapid connection to the reinforcing cage by incorporating a clamp with a single-sided opening at the bottom of the sinker component. Simultaneously, through-holes for rope threading are provided on both sides of the clamp's opening. The end of the closing rope can pass through or be withdrawn from these holes, allowing the clamp's opening to be closed or opened. This enables the sinker component to be securely connected to the reinforcing cage via the closing rope, offering the advantages of convenient and rapid connection. Furthermore, after concrete pouring, the closing rope can be removed, allowing the sinker component to detach from the reinforcing cage and be reused, reducing construction costs.

[0017] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figure 1 and 2 As shown, an installation structure for reinforcing bars in bored piles is provided to allow workers to apply downward pressure to the reinforcing bar cage 1 during concrete pouring into the pile pit containing the cage, preventing the cage 1 from floating. The installation structure includes a sinker 2 and a closing rope 3. The sinker 2 consists of an upper pressure-applying section 4 and a lower clamping section 5. The clamping section 5 has a C-shaped structure with an opening on one side, and rope holes for the closing rope 3 are provided at both ends of the clamping section 5. The end of the closing rope 3 can pass through or be withdrawn from the rope holes, thereby closing or opening the clamping section 5.

[0020] Specifically, one end of the sealing rope 3 passes through two rope holes in sequence to close the opening of the clamp part 5. After passing through the two rope holes, the end of the sealing rope 3 is folded upward and tied to the other end of the sealing rope 3 to form a closed ring structure. When the two ends of the sealing rope 3 are untied and pulled out from the two rope holes, the opening of the clamp part 5 is opened.

[0021] Furthermore, such as Figure 3 As shown, the clamp part 5 is divided into a middle connecting section 5-1 and two end clamping sections 5-2. The two end clamping sections 5-2 are parallel to each other. Two rope holes are respectively opened at the outer ends of the clamping sections 5-2.

[0022] Furthermore, a hook 6 is fixed to the top of the pressure section 4, so that when the sunken part 2 is subsequently removed, the workers can use the rope hoisted on the hook 6 to remove the sunken part 2 from the uncured concrete.

[0023] In this embodiment, there are two sinking components 2, which are symmetrically installed on both sides of the steel cage 1, and each has a sealing rope 3 at its bottom.

[0024] The steel reinforcement cage 1 has a cylindrical structure, including multiple main reinforcing bars 7 and multiple stirrups 8. The main reinforcing bars 7 are parallel to each other and arranged in a circumferential array to form the main body of the cage. The stirrups 8 are fixed to the main body of the cage at intervals to secure the relative positions of the main reinforcing bars 7. The stirrups 8 extend into the openings of the clamping parts 5 in the sinker 2. During use, when workers apply downward pressure to the sinker 2, the pressure is transferred to the stirrups 8 through the clamping parts 5 on the sinker 2, effectively preventing the steel reinforcement cage 1 from floating.

[0025] In this embodiment, the stirrup 8 is a spiral stirrup 8.

[0026] The working principle of this utility model is as follows: In actual use, workers tie the steel cage 1 to the ground. The clamping part 5 of the sinker 2 is then used to clamp the stirrups 8 in the steel cage 1 from the inside out. After threading one end of the sealing rope 3 through the two rope holes on the clamping part 5, the steel cage 1 is lowered into the corresponding pile pit. Workers then pour concrete into the pile pit and continuously apply downward pressure to the steel cage 1 through the sinker 2 to prevent it from floating.

[0027] After the concrete pouring is completed, the workers untie both ends of the sealing rope 3 and pull it out of the rope hole on the sinker 2, thus reopening the opening of the clamp part 5 in the sinker 2. The workers then move the sinker 2 laterally to separate the clamp part 5 from the steel cage 1. An upward pulling force is then applied to the sinker 2 to remove it from the concrete. The sinker 2 is then cleaned and used for the subsequent installation and pouring of the steel cage 1.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
