Description

Technical Field

[0001] The utility model relates to the field of infrastructure construction, in particular to an anti-floating and recyclable hanging rod. Background Art

[0002] The current engineering construction uses a large number of bored cast-in-place pile technologies. Bored cast-in-place piles refer to piles made by mechanically drilling in the foundation soil at the construction site, placing a steel cage inside and pouring concrete. According to the pile-making process, they are divided into dry-operation bored cast-in-place piles, mud-wall bored cast-in-place piles and full-casing bored cast-in-place piles. Among them, during the concrete pouring process of the mud-wall bored cast-in-place piles, the concrete will form a force that causes the steel cage to float, which is prone to "floating cage" accidents. At the least, it affects the quality of the pile and the strength of the pile body, and at the worst, it will cause the pile to be abandoned. Therefore, it is extremely important to solve the problem of the floating of the steel cage caused by the concrete pouring during the construction of bored cast-in-place piles.

[0003] The existing technology has some disadvantages. Some construction sites increase the diameter and number of hanging bars, and add counterweights at the wellhead or weld them to the casing to prevent the steel cage from floating up. The process is complicated and takes up construction time. The steel cage hanging bars and anti-floating measures in the existing technology are difficult to reuse, resulting in a large amount of steel waste and increased construction costs. The existing technology is difficult to achieve subtle adjustments to the position of the steel cage, and can only significantly displace the steel cage, and the pile top elevation is difficult to control. Utility Model Content

[0004] The utility model aims to overcome the shortcomings of the prior art and provide an anti-floating and recyclable hanging rod to solve at least one of the above technical problems.

[0005] The purpose of the utility model is achieved through the following technical solutions: an anti-floating recyclable hanger, comprising a load-bearing beam and a tension rod; the load-bearing beam is located at the top of the pile hole, and the two ends of the load-bearing beam are erected on the ground; the tension rod is vertically arranged, and a fixed structure is arranged at the bottom end of the tension rod, and the fixed structure is detachably connected to the steel cage; a connecting component is arranged on the tension rod, and the connecting component is connected to the load-bearing beam; an auxiliary stabilizing structure is arranged on the tension rod, and the auxiliary stabilizing structure is detachably connected to the casing.

[0006] The utility model fixes the steel cage on the load-bearing beam by using a tie rod, thereby preventing the steel cage from floating up during concrete pouring and ensuring the quality of pile formation. At the same time, by arranging a fixing structure detachably connected to the steel cage at the bottom of the tie rod, after the concrete pouring is completed and the initial setting, the tie rod can be separated from the steel cage, and the suspension rod can be recovered so that the suspension rod can be reused.

[0007] In some embodiments, the connecting component includes a connecting sleeve and a connecting sleeve mounting plate arranged on one side of the connecting sleeve, the connecting sleeve is sleeved on the stress beam, and the connecting sleeve mounting plate is connected to the pull rod. The pull rod can be quickly fixed to the stress beam through the connecting component.

[0008] In some embodiments, the cross section of the stress beam is rectangular, and the inner contour of the connecting sleeve is a rectangle corresponding to the cross section of the stress beam. The stress beam is set to a rectangle, and the connecting sleeve is set to a rectangle at the same time, so that after the connecting sleeve is set on the stress beam, the connecting sleeve is prevented from rotating circumferentially around the stress beam.

[0009] In some embodiments, the auxiliary stabilizing structure includes a stabilizing structure mounting plate and a clamping plate arranged on the stabilizing structure mounting plate, the stabilizing structure mounting plate is connected to the pull rod, two clamping plates are arranged on the stabilizing structure mounting plate at intervals, a downward bayonet is formed between the two clamping plates, and the bayonet is used to clamp the top of the casing. Through the two clamping plates, the auxiliary stabilizing structure can be quickly clamped on the top of the casing.

[0010] In some embodiments, one of the clamping plates is provided with a set bolt, and the set bolt is used to abut the casing. The top of the casing is abutted against the clamping plate by the set bolt to improve stability.

[0011] In some embodiments, the pull rod includes a threaded screw rod, the threaded screw rod is passed through the connecting sleeve mounting plate, and the threaded screw rod is provided with first adjustment nuts on both sides of the connecting sleeve mounting plate, and the two first adjustment nuts are used to adjust the position of the connecting sleeve mounting plate on the threaded screw rod. By adjusting the position of the two first adjustment bolts on the pull rod, the axial position of the connecting sleeve on the pull rod is adjusted, and then the height of the steel cage is adjusted.

[0012] In some embodiments, the threaded screw is passed through the stabilizing structure mounting plate, and second adjusting nuts are provided on both sides of the threaded screw on the stabilizing structure mounting plate, and the two second adjusting nuts are used to adjust the position of the stabilizing structure mounting plate on the threaded screw. After the height of the steel cage is adjusted, a second adjusting nut is provided so that the auxiliary stabilizing structure can be connected to the casing. By adjusting the position of the second adjusting nut on the pull rod, the position of the auxiliary stabilizing structure on the pull rod is adjusted so that the auxiliary stabilizing structure can be connected to the top of the casing.

[0013] In some embodiments, the fixing structure includes two clips, which are arranged at intervals at the bottom end of the pull rod, and the gap between the two clips is used to clamp the annular stirrups of the steel cage. The two clips facilitate the direct insertion of the annular stirrups of the steel cage, and after the initial setting of the concrete, the two clips can be easily detached from the steel cage to recover the hanger bars.

[0014] The utility model has the following advantages:

[0015] By connecting the tie rod to the load-bearing beam and then utilizing the fixing structure at the bottom of the tie rod to detachably connect the tie rod to the steel cage, the height of the steel cage is fixed to prevent the steel cage from floating when concrete is poured; at the same time, since the tie rod is detachably connected to the steel cage through the fixing mechanism, the tie rod can be removed after the initial setting of the concrete is completed for subsequent recycling; and the position of the connecting sleeve on the tie rod can be adjusted through the first adjusting nut, thereby adjusting the height of the steel cage.
