Description

Technical Field

[0001] The utility model relates to the field of bored pile construction, in particular to a bored pile reinforcement cage suspension bar which can be recycled. Background Art

[0002] The bored cast-in-place pile construction technology has low cost and simple operation. It has been widely used in various construction fields of building engineering. The construction process of mud wall bored cast-in-place pile mainly includes: casing burial, drilling rig positioning, hole forming, waste slurry removal, first hole cleaning, lowering steel cage and steel conduit, second hole cleaning, pouring underwater concrete, and pile forming.

[0003] Among them, the currently commonly used method of lowering the steel cage is to use several plain round steel bars as disposable hanging bars and weld them to the main bars of the steel cage, bend the upper end of the round steel bar into a ring, and then use a lifting device to put the plain round steel bar and the steel cage into the pile hole together, and fix the upper end of the plain round steel bar on the shoulder beam of the steel cage lowering platform, and then pour concrete in the pile hole. After the concrete solidifies, these plain round steel bars will also solidify inside the bored pile. This results in a large number of plain round steel bars being buried in the concrete during the bored pile construction process and cannot be reused, thereby increasing the construction cost and causing a waste of resources. At the same time, the welding of plain round steel bars also requires manpower and material resources, which reduces construction efficiency. Utility Model Content

[0004] The present application provides a recyclable bored pile reinforcement cage hanger, which can reduce the waste of resources caused by using plain round reinforcement as disposable hangers when placing the reinforcement cage into the pile hole, reduce construction costs, reduce the time required for welding plain round reinforcement each time it is placed, and improve construction efficiency.

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] The present application provides a recyclable bored pile reinforcement cage suspension bar, which includes a recovery part and a dividing part. The recovery part is mainly used to connect with the lifting equipment, increase the lowering path, reduce the dividing length of the dividing part, save resources, and can also finely adjust the lowering angle of the reinforcement cage during the process of lowering the reinforcement cage. The dividing part is connected to the reinforcement cage. After the reinforcement cage is lifted into place using the recovery part, the construction personnel cut off the dividing part and retrieve the recovery part to facilitate the next recycling.

[0027] Specifically, Figure 11 is a schematic diagram of a recyclable bored pile steel cage suspension bar structure provided in an embodiment of the present application. The recycling part includes an upper suspension plate 1, and a lower suspension plate 4 is arranged at the bottom of the upper suspension plate 1. The upper suspension plate 1 and the lower suspension plate 4 are connected by an adjustment steel bar 3. The specification and length of the adjustment steel bar 3 can be calculated and determined according to the actual use situation by the top elevation of the casing and the top elevation of the pile. When using the present application, after the steel cage suspension bar in the embodiment of the present application is connected to the steel cage, the hoisting equipment needs to first hoist it through the upper suspension plate 1. In order to facilitate the hoisting work A lifting part 101 is provided on the top of the upper hanging plate 1. In actual use, the lifting part 101 can be a lifting wire rope, or a hook can be provided on the top of the upper hanging plate 1, etc., which can firmly connect the lifting equipment and withstand the lifting weight of the lifting steel cage. There is no specific limitation in the embodiment of the present application. The lower hanging plate 4 can not only help the upper hanging plate 1 to disperse part of the gravity of the steel cage, thereby increasing the overall bearing capacity of the suspension bar in the present application, but also facilitate fine adjustment of the angle and position of the steel cage during the lowering process.

[0028] Figure 2 A schematic structural diagram of adjusting the steel bars 3, the first sleeve 601 and the second sleeve 602 in a recyclable bored pile steel cage suspension bar provided in an embodiment of the present application. Specifically, in order to ensure the safety of the lifting work and meet the load-bearing requirements of the lifting, the upper hanging plate 1 and the lower hanging plate 4 are made of steel. In actual use, the upper hanging plate 1 and the lower hanging plate 4 are welded on four sides of a plurality of steel bars and two steel plates, and the length and height of the weld meet the relevant lifting requirements. Specifically, the upper hanging plate 1 includes a first component steel bar 102, one end of the first component steel bar 102 extends out of the bottom of the upper hanging plate 1, and a threading portion is provided at the end of the first component steel bar 102 extending out of the bottom of the upper hanging plate 1. Similarly, the lower The hanger plate 4 includes a second component steel bar 401, one end of the second component steel bar 401 extends out of the top of the lower hanger plate 4, and the end of the second component steel bar 401 extending out of the lower hanger plate 4 is also provided with a threaded portion. At the same time, sleeve connections are provided between the adjustment steel bar 3 and the upper hanger plate 1 and between the adjustment steel bar 3 and the lower hanger plate 4. Specifically, threaded portions are provided at both ends of the adjustment steel bar 3. A first sleeve 601 is provided at the connection between the threaded portion of the first component steel bar 102 and the threaded portion of one end of the adjustment steel bar 3, and a second sleeve 602 is provided at the connection between the threaded portion of the second component steel bar 401 and the threaded portion of the other end of the adjustment steel bar 3, so as to ensure a stable connection between the adjustment steel bar 3 and the upper hanger plate 1 and the lower hanger plate 4.

[0029] Furthermore, a fixing steel wire 603 is provided on both the first sleeve 601 and the second sleeve 602. After connecting the upper hanging plate 1, adjusting the steel bars 3 and the lower hanging plate 4, the fixing steel wire 603 is tightly wound around the surfaces of the first sleeve 601 and the second sleeve 602. The fixing steel wire 603 can limit the first sleeve 601 and the second sleeve 602 to a certain extent to prevent the first sleeve 601 and the second sleeve 602 from falling off after long-term use, thereby preventing a safety accident. At the same time, there is no specific restriction on the winding height of the fixing steel wire 603. It can be wound only around the connecting points at both ends of the first sleeve 601 and the second sleeve 602, or it can be wound around the entirety.

[0030] The recovery part also includes a recovery wire rope 2, and a connecting pin 201 is arranged at the bottom of the recovery wire rope 2. The connecting pin 201 is a commonly used pin on the market, and a pin hole is arranged at the tail end thereof. The recovery wire rope 2 passes through the pin hole at the tail end of the connecting pin 201. The recovery wire rope 2 can be arranged separately from the upper hanging plate 1, and can also be arranged on the upper hanging plate 1. In the present application, the bottom of the dividing part is connected to the steel cage, and the connecting pin 201 is used to fix the connection between the bottom of the dividing part and the steel cage. When the steel cage is hoisted into the pile hole drilled in advance and the pouring work is completed, the dividing part is cut off, and then the recovery wire rope 2 is pulled to recover the connecting pin 201.

[0031] Figure 3 A schematic diagram of a hoisting wire rope 5 in a recyclable bored pile reinforcement cage suspension bar provided in an embodiment of the present application, the dividing part also includes a hoisting wire rope 5 arranged at the bottom of a lower suspension plate 4, one end of the hoisting wire rope 5 is fixedly connected to the lower suspension plate 4, and the other end is provided with a fixing hook 501, the fixing hook 501 is often used in conjunction with a lifting ear pre-arranged on the reinforcement cage, and can also be directly hooked to the main reinforcement at the top of the reinforcement cage, and then the connecting pin 201 at the bottom of the recovery wire rope 2 is used to pass through the connection between the fixing hook 501 and the reinforcement cage, the tail end of the connecting pin 201 faces upward, and the fixing hook 501 and the lifting ear on the reinforcement cage are blocked by the wider head end of the connecting pin 201. After the hoisting is completed, the connecting pin 201 is taken out from the opening between the fixing hook 501 and the lifting ear on the reinforcement cage by the recovery wire rope 2 to complete the recycling work.

[0032] During the process of lowering the steel cage, due to the heavy weight of the steel cage and the deep lowering distance, a slight swing of the lifting equipment may cause the steel cage below to shake greatly. Therefore, the connecting pin 201 can ensure that the steel cage is firmly connected to the fixing hook 501 to prevent the steel cage from shaking due to wind or other factors during the lowering process, resulting in the detachment of the steel cage and the fixing hook 501, causing a safety accident. After the lifting is completed, the recovery wire rope 2 is used to pull up the connecting pin 201 for recovery. In the embodiment of the present application, the fixing hook 501 can also use other types of fixing parts, which can ensure stable suspension with the steel cage without affecting the recovery of the connecting pin 201.

[0033] When using the steel cage hanging rod in this application, in order to ensure the balance of the steel cage during the lifting process, generally four steel cage hanging rods in the application are used in combination and connected to the four balance points on the top of the steel cage respectively. Specifically, Figure 4 A schematic diagram of the use status of a recyclable bored pile steel cage hanging bar provided in an embodiment of the present application. Before using the steel cage hanging bar in the present application, first connect and fix the upper hanging plate 1, the adjustment steel bar 3 and the lower hanging plate 4 of the four hanging bars through the first sleeve 601 and the second sleeve 602 respectively, then tighten the connection with a wrench, and use the fixing steel wire 603 to wrap and reinforce the first sleeve 601 and the second sleeve 602 respectively, then ensure that the top end of the lifting wire rope 5 is firmly connected to the bottom of the lower hanging plate 4, and the bottom end of the lifting wire rope 5 is connected to the lifting ear welded on the main reinforcement of the steel cage through a connecting pin The upper hanging plate 1 in the hanging rod is fixed on the shoulder beam of the lowering platform of the steel cage, and then the concrete is poured into the pile hole. After the pile foundation is poured, the adjusting steel bar 3 is cut off. The cutting height is determined according to the lowering depth of the adjusting steel bar 3. However, a certain length must be retained between the cutting part and the bottom of the first sleeve 601 to facilitate the removal of the remaining adjusting steel bar 3 in the first sleeve 601. Then, the recovery wire rope 2 is pulled, and after the connecting pin 201 is pulled out, the upper hanging plate 1 is recovered to facilitate the next reuse.

[0034] The steel cage hanging rod in the present application has a simple structure and is easy to use. It can replace the disposable hanging rods welded on the steel cage during traditional lifting of the steel cage. At the same time, the recovery part can also increase the lowering path, reduce the dividing length of the dividing part, save resources, and reduce the steel bar materials discarded when placing the steel cage. The recovery part can be recycled many times, which greatly reduces the construction cost and avoids waste of resources. At the same time, it also reduces the construction time spent on welding temporary hanging rods and improves construction efficiency.
