Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a reusable suspension bar device for bored cast-in-place concrete pile construction. Background Technique

[0002] The bored cast-in-place piles in deep foundation pits are all constructed by bored cast-in-place piles on the original ground. In this way, there is a quite long part of empty piles between the pile top and the original ground. After the drilling is completed, the steel reinforcement cage is mainly lowered by welding a certain length of suspension bars at both ends of the steel reinforcement cage, hoisting it to the hole opening by a crane, and then lowering the steel reinforcement cage, and then cutting off the suspension bars subsequently.

[0003] Among them, the "device for hoisting the suspension bar of a deep-buried diaphragm wall steel reinforcement cage and its construction method" disclosed in the patent application number "CN201810810799.9" "relates to the field of construction engineering, and solves the technical problem that when the groove depth for lowering the steel reinforcement cage is relatively deep, long lifting rings need to be welded, and at this time, the construction time is long, reducing the hoisting efficiency of the steel reinforcement cage. The key points of its technical solution are: including a plurality of steel pipes arranged on the suspension bar truss at the head of the steel reinforcement cage, and long suspension bars passing through the steel pipes. Limiters for restricting the movement of the long suspension bars in the steel pipes are arranged at both ends of the steel pipes where the long suspension bars extend, and a lifting ring is arranged at the end of the long suspension bar far from the steel reinforcement cage; its advantage is that it saves the time for welding the lifting ring when replacing the lifting ring of the steel reinforcement cage and reduces the total hoisting time", but in the actual use process of this kind of device for hoisting the suspension bar of the steel reinforcement cage, there are still the following defects:

[0004] During the construction of bored cast-in-place piles, the installation of the steel reinforcement cage usually adopts the "suspension bar" method. This method wastes a lot of suspension bar materials and cannot be recycled and reused. Moreover, the welding of the suspension bars is time-consuming. After the pile hole is filled with cast-in-place concrete, the long suspension bars are poured into the concrete and cannot be quickly taken out for reuse after the concrete pouring is completed, resulting in the problem that the suspension bars cannot be recycled and used, causing waste.

[0026] Embodiment 1

[0027] As Figures 1-4 shown, a reusable suspension bar device for the construction of bored cast-in-place concrete piles proposed by the present utility model includes a construction hoisting frame 1. Four corners at the bottom end of the construction hoisting frame 1 are fixedly connected with support legs 101. A fixed cross column 102 is fixedly connected to the side of each support leg 101. A support mechanism 2 is fixedly connected to the bottom of one end of the fixed cross column 102;

[0028] A hoisting mechanism 3 is arranged at the top of one end of the construction hoisting frame 1, and a moving adjustment mechanism 4 is arranged at the top of the construction hoisting frame 1.

[0029] During specific use, the fixed crossbars 102 on the four support legs 101 at the bottom of the construction hoisting frame 1 are used to facilitate the fixed installation of the support mechanism 2. Through the setting of the support mechanism 2, when hoisting the steel cage suspension bars during the construction of bored cast-in-place piles, in order to prevent the construction hoisting frame 1 from moving, the support mechanism 2 is used to hoist and support the construction hoisting frame 1. The moving and adjusting mechanism 4 is set to move the hoisting point of the hoisting mechanism 3, so as to better hoist and adjust the steel cage and place it into the bored hole.

[0030] The support mechanism 2 includes a device frame fixedly connected to the bottom end of a first electric hydraulic rod 201 fixedly connected to the bottom of one end of the fixed crossbar 102. The bottom end of the device frame is fixedly connected to a support fixing frame 202. Four corners at the bottom end of the support fixing frame 202 are fixedly connected to first support bases 203, and the middle of the bottom end of the support fixing frame 202 is fixedly connected to a second support base 204. Rubber cushion blocks 205 are fixedly connected to the bottom ends of both the first support base 203 and the second support base 204.

[0031] During specific use, during the construction process, when hoisting and feeding the steel cage, in order to prevent the construction hoisting frame 1 from shaking during the hoisting process, the first electric hydraulic rod 201 connected to the bottom end of the fixed crossbar 102 is extended and retracted to push the support fixing frame 202, so that the bottom ends of the first support base 203 and the second support base 204 are in contact with the ground, thus facilitating the support of the construction hoisting frame 1 and preventing it from moving during hoisting. The rubber cushion blocks 205 are provided to prevent the first support base 203 and the second support base 204 from being damaged during use.

[0032] The hoisting mechanism 3 includes a first driving motor 301 fixedly connected to one side of the top of the construction hoisting frame 1. The driving end of the first driving motor 301 is fixedly connected to a rotating shaft 302. Two winding drums 303 are fixedly connected to the outer side of the rotating shaft 302.

[0033] During specific use, after the pile hole is cast in place, the longer hanging rod 304 is cast in the concrete. After the concrete is cast, it is necessary to quickly take it out and reuse it so that the hanging rod 304 can be reused to avoid waste. The rotation of the first driving motor 301 drives the rotating shaft 302 to rotate, and the rotation of the rotating shaft 302 causes the two winding rollers 303 to rotate, so that the hanging rod 304 can be rolled up and pulled out of the casting hole. The rotation of the two second driving motors 305 makes it easier for the movable sliding seat 307 on the screw rod 306 to slide back and forth, so as to facilitate the adjustment of the position of the rolling wheel 308, so as to facilitate the feeding of the hanging rod through the rolling wheel 308 when the hanging rod is rolled up. At the same time, the limiting frame 309 is set to prevent the hanging rod 304 from being entangled, so as to facilitate recycling.

[0034] The movable adjustment mechanism 4 includes a slide rail 401 fixedly connected to both sides of the top of the construction lifting frame 1, a driving wheel 402 and a driven wheel 403 are fixedly connected to the top in the middle of both ends of the construction lifting frame 1, a transmission belt 404 is connected to the outer side of the driving wheel 402 and the driven wheel 403, a moving seat 405 is fixedly connected to the bottom end of the transmission belt 404, and the bottom of both ends of the moving seat 405 is slidably connected to the slide rail 401, a hanger 406 is fixedly connected to the bottom end of the slide rail 401, and an interlaced slide groove 407 is movably fixedly connected to the bottom end of the hanger 406, and a small driving motor is fixedly connected to one side of the driving wheel 402.

[0035] During specific use, when the hanging rod 304 is lowered to the steel cage, in order to facilitate the lifting and adjustment of the steel cage, the rotation of the small driving motor is used to drive the active wheel 402 to rotate, and the rotation of the active wheel 402 causes the transmission belt 404 to rotate, which is convenient for coordinating with the rotation of the driven wheel 403, and convenient for sliding adjustment of the moving seat 405 slidably connected to the top of the slide rail 401, so that the moving seat 405 drives the hanger 406 to adjust the position at the top of the pouring hole, and at the same time drives the hanging rod 304 inserted into the slide groove 407 to move, thereby facilitating the lowering of the steel cage.

[0036] The interior of the interlaced slide groove 407 is interlaced with the suspension rod 304 .

[0037] During specific use, the hanging rod 304 and the interlacing slide groove 407 are interlaced to facilitate the control of the hanging rod 304.

[0038] A switch panel is fixedly connected to one side of the construction hoisting frame 1, and a protective layer is provided on the surface of the switch panel.
