Description

Technical Field

[0001] The utility model relates to the technical field of positioning of embedded connectors in the pile body of bored cast-in-place piles, and particularly relates to a positioning device for embedded connectors in the pile body of bored cast-in-place piles. Background Art

[0002] In the prior art, the embedding depth control of the embedded connector in the pile body of the bored cast-in-place pile generally controls the embedding depth of the connector by measuring the elevation of the top of the steel reinforcement cage and calculating the elevation difference; for the embedded concrete waist beam connector in the retaining pile body of the subway station foundation pit, the embedding depth is large, the azimuth deviation requirement is small, and the accuracy requirement is high. The direction of the embedded connector in the pile body is marked on the top of the steel reinforcement cage, and the azimuth of the embedded connector in the pile body is controlled by measuring the coordinates of the mark on the top of the steel reinforcement cage.

[0003] The measurement of the elevation of the top of the steel reinforcement cage of the bored cast-in-place pile and the coordinates of the marked point can only be carried out after the installation of the steel reinforcement cage is completed. During the installation process of the steel reinforcement cage, only the depth and azimuth of the embedded connector in the pile body can be roughly controlled by experience and observation, and the control accuracy is difficult to detect. After the installation of the steel reinforcement cage is completed, there are often problems such as large deviation in the embedding depth position and over-limit deviation in the embedding azimuth, and then it is necessary to lift the steel reinforcement cage and reinstall it, which often causes quality problems such as deformation, damage, and collapse of the hole wall of the steel reinforcement cage; at the same time, the rework treatment increases additional construction risks, construction period, and cost. Therefore, in view of this technical problem, the present application proposes a positioning device for embedded connectors in the pile body of bored cast-in-place piles.

After the installation of the embedded connector in the pile body of the bored cast-in-place pile is completed, the slide rail can be disassembled and pulled out through the insertion between the insertion block and the slot and the threaded connection between the slide rod and the fixed ring, and the embedding positioning efficiency of the embedded connector in the pile body of the bored cast-in-place pile is improved through a simple structure and operation.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0023] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: a positioning device for pre-buried connectors on the pile body of a bored cast-in-place pile, including:

[0024] A support cage 1 for support. The inner wall of the support cage 1 is installed with a plurality of slide rails 2 through the insertion connection between the insertion blocks 8 and the slots 9 for the disassembly between the support cage 1 and the slide rails 2. A slider 11 is slidably connected inside each of the plurality of slide rails 2. A support ring 7 is fixedly connected to the adjacent sides of the plurality of sliders 11 to control the sliding of the support ring 7 inside the slide rail 2;

[0025] The main body of the steel reinforcement cage 5 is connected to the support ring 7 through the cooperation between the fixing ring 10 and the sliding rod 6 for the disassembly between the main body of the steel reinforcement cage 5 and the support ring 7. A plurality of insertion shafts 3 are fixedly connected to the bottom side of the support cage 1, and a tapered head is fixedly connected to the bottom end of each of the plurality of insertion shafts 3;

[0026] Specifically, first, the fixing ring 10 is installed and fixed on the outer wall of the main body of the steel reinforcement cage 5, and then the support ring 7 is sleeved down from the top of the main body of the steel reinforcement cage 5 to make the fixing ring 10 stuck on the bottom side of the support ring 7. Then, some tools are connected through the connection head 12 to control the rotation of the sliding rod 6, and the support ring 7 and the fixing ring 10 are connected through the sliding rod 6. Finally, the slide rail 2 and the support cage 1 are installed through the insertion connection between the insertion block 8 and the slot 9. At the same time, the bottom end of the slot 9 can prevent the insertion block 8 from slipping off the inner wall of the support cage 1, so as to control the sliding of the main body of the steel reinforcement cage 5 inside the slide rail 2. The sliding of the main body of the steel reinforcement cage 5 inside the slide rail 2 can accurately control the embedding depth of the pre-buried connector on the pile body. At the same time, the insertion shaft 3 can insert the support cage 1 at a suitable position and fix it, which can support and fix the slide rail 2, facilitating the subsequent control of the lifting and lowering of the main body of the steel reinforcement cage 5 through the slide rail 2 to accurately control the embedding depth of the pre-buried connector on the pile body of the bored cast-in-place pile, avoiding problems such as large deviation in the embedding depth position and excessive deviation in the embedding azimuth after the installation of the main body of the steel reinforcement cage 5, and then the rework treatment of lifting the steel reinforcement cage and reinstalling it, which often causes quality problems such as deformation, damage, and collapse of the hole wall of the steel reinforcement cage.

[0027] Refer to Figures 1 - 3, the slot 9 located on the inner wall of the support cage 1, the outer wall of the slide rail 2 is fixedly connected with a plug 8, the plug 8 is arranged inside the slot 9, the fixing ring 10 located on the outer wall of the steel reinforcement cage body 5, the top side of the support ring 7 is threadedly connected with a plurality of slide rods 6, the top side of the fixing ring 10 is provided with a plurality of threaded holes, and the slide rods 6 are threadedly connected inside the threaded holes. The top sides of the slide rails 2 are fixedly connected with fixing plates 4, the top ends of the slide rods 6 are arranged inside the fixing plates 4, and the top sides of the plurality of slide rods 6 are fixedly connected with connecting heads 12;

[0028] Specifically, the insertion connection between the slot 9 and the plug 8 facilitates the extraction of the slide rail 2 from the inner wall of the support cage 1 after embedding. The fixing ring 10 fixed on the outer wall of the steel reinforcement cage body 5 can cooperate with the support ring 7, and then the connection between the support ring 7 and the fixing ring 10 is achieved through the slide rod 6. After the support ring 7 and the fixing ring 10 are connected, the sliding of the steel reinforcement cage body 5 inside the slide rail 2 can be controlled to accurately control the depth and orientation of the pile body embedded connector. The fixing plate 4 can provide support when the slide rod 6 moves up and down. The shape of the connecting head 12 can be changed according to requirements to facilitate connection with different tools, and the rotation of the slide rod 6 is controlled to achieve the connection and fixation between the fixing ring 10 and the support ring 7, which is convenient for the subsequent detachment of the support cage 1, the slide rail 2, the support ring 7 and the steel reinforcement cage body 5, and is convenient for achieving the accurate positioning of the pile body embedded connector of the bored cast-in-place pile through a simple structure and operation, which is convenient for improving work efficiency.

[0029] Working principle: First, the support cage 1 is inserted into a suitable position through the insertion shaft 3 and the conical head at the bottom, and the support cage 1 is fixed at the required position to position the steel reinforcement cage body 5. Then, after the fixing ring 10 is fixed on the outer wall of the steel reinforcement cage body 5, the support ring 7 is sleeved from the top of the steel reinforcement cage body 5, and the connection between the support ring 7 and the fixing ring 10 is achieved through the slide rod 6, so as to connect the steel reinforcement cage body 5 and the slide rail 2. The slide rail 2 is installed with the support cage 1 through the insertion connection between the plug 8 and the slot 9. The simple structure facilitates the subsequent disassembly of the slide rail 2. At the same time, by controlling the sliding of the slider 11 inside the slide rail 2 to drive the support ring 7 to slide, the steel reinforcement cage body 5 fixed on the inner circumference of the support ring 7 is lifted and lowered, so as to accurately control the depth of the pile body embedded connector of the bored cast-in-place pile buried inside the bored cast-in-place pile hole according to the sliding length of the slider 11 inside the slide rail 2.
