Description

Technical Field

[0001] This utility model relates to the field of cast-in-place pile construction technology, and in particular to a lattice column positioner for bored cast-in-place piles. Background Technology

[0002] The construction of a combined structure of internally supported cast-in-place piles and lattice columns is an energy-saving and environmentally friendly construction technique that is being gradually promoted in the national construction industry. According to the requirements of the foundation pit support drawings and the superstructure design drawings, the lower part of the foundation slab adopts cast-in-place piles, and the upper part of the foundation slab adopts steel lattice columns as internal support beams. The lattice columns bear the load of the upper internal support beams, and the independent height can reach 13-20m. They can be reused.

[0003] In conventional construction, the lattice column is required to be inserted 3 meters into the reinforcing cage of the cast-in-place pile. During pouring, a guide pipe is installed inside the lattice column, and the pouring process is the same as that for underwater concrete. Currently, no corresponding positioning device is used in the construction process. After the bored cast-in-place pile for the lattice column is mechanically drilled, the reinforcing cage is installed, and the lower cast-in-place pile concrete is poured to the required elevation, a crane lifts the lattice column to a position approximately 3 meters inside the cast-in-place pile.

[0004] In conventional processes, the hoisting and positioning of lattice columns relies entirely on the workers at the top of the borehole to straighten and check them. It is difficult to control the deviation and angle of the cast-in-place pile lattice columns, and it depends entirely on the experience of the on-site workers and the coordination between the crane operators. As a result, the construction quality cannot be effectively guaranteed. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a borehole grouting pile grid column positioner.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A lattice column positioner for bored piles includes a lattice column and a positioning platform. The positioning platform is provided with adjustable feet on its side, a bar-type level and lifting lugs on the positioning platform, and a turntable rotatably mounted on the upper side of the positioning platform. The positioning platform and the turntable have a circular hole in the middle to accommodate the lattice column. A hydraulic cylinder is provided inside the circular hole of the turntable. Multiple sets of hydraulic cylinders are provided and are arranged corresponding to the lattice column. An anti-slip pad is provided at one end of the hydraulic cylinder and abuts against the side wall of the lattice column. A brake is provided on the upper side of the positioning platform. The brake includes a guide rod and a magnetic plate.

[0008] Preferably, the adjustable support leg includes a telescopic rod and a pad, with the upper end of the telescopic rod connected to a turntable and the lower end of the telescopic rod connected to the pad.

[0009] Preferably, the bar level is provided in multiple sets, evenly arranged on the upper side of the positioning platform, and the multiple sets of the bar level are arranged longitudinally and laterally.

[0010] Preferably, the upper side of the positioning platform is provided with a limiting wheel, and there are multiple sets of limiting wheels arranged in a circular array. The lower side of the turntable is provided with a ring corresponding to the limiting wheel.

[0011] Preferably, a fixed seat is provided on the upper side of the positioning platform, the guide rod is slidably connected to the fixed seat, and one end of the guide rod is fixedly connected to the magnetic sheet.

[0012] Preferably, the magnetic sheet is arc-shaped and adapted to the outer contour of the turntable, and the magnetic sheet and the turntable are in contact by magnetic attraction.

[0013] The beneficial effects of this utility model are as follows:

[0014] Compared with the prior art, the positioning device of this utility model includes a positioning platform and a turntable. The bottom of the positioning platform is equipped with adjustable support feet. The positioning platform is corrected by a bar level to prevent the positioning platform from tilting. Multiple sets of hydraulic cylinders clamp the lattice column and control its extension and retraction. With the help of the turntable, the misalignment and angle deviation of the lattice column can be quickly and effectively corrected. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] Reference Figure 1-3A drilled pile lattice column positioner includes a lattice column 1 and a positioning platform 2. The positioning platform 2 is provided with an adjustable support foot 3 on its side. The adjustable support foot 3 includes a telescopic rod 31 and a pad 32. The telescopic rod 31 is divided into two sections and is connected by threads. The upper end of the telescopic rod 31 is connected to a turntable 4, and the lower end of the telescopic rod 31 is connected to the pad 32. The pad 32 is in contact with the ground. The height of the positioning platform 2 is adjusted by the telescopic rod 31 to ensure that the positioning platform 2 is set horizontally.

[0021] The positioning platform 2 is equipped with a strip level 6 and a lifting lug 7. The lifting lug 7 facilitates the hoisting of construction personnel and improves the convenience of construction. There are multiple sets of strip levels 6, which are evenly distributed on the upper side of the positioning platform 2. The multiple sets of strip levels 6 are arranged longitudinally and laterally to facilitate the leveling of the positioning platform 2 by construction personnel.

[0022] The positioning platform 2 is rotatably equipped with a turntable 4 on its upper side, and a limiting wheel 41 is rotatably equipped on its upper side. Multiple sets of limiting wheels 41 are provided and arranged in a circular array. The lower side of the turntable 4 is equipped with a ring corresponding to the limiting wheel 41. The position of the turntable 4 is restricted by the limiting wheel 41 to prevent the turntable 4 from shifting position when rotating. The positioning platform 2 and the turntable 4 are detachable for easy handling and maintenance.

[0023] The positioning platform 2 and the turntable 4 are provided with a circular hole in the middle to accommodate the lattice column 1. The lattice column 1 passes through the circular hole and is embedded in the drilled hole. The turntable 4 is provided with a hydraulic cylinder 5 inside the circular hole. There are multiple sets of hydraulic cylinders 5, which are arranged corresponding to the lattice column 1. The multiple sets of hydraulic cylinders 5 abut against the lattice column 1 from four sides to determine the planar position of the lattice column 1. One end of the hydraulic cylinder 5 is provided with an anti-slip pad, which abuts against the side wall of the lattice column 1 to prevent the lattice column 1 from sliding or shaking and causing positional deviation.

[0024] A brake is provided on the upper side of the positioning platform 2. After the turntable 4 rotates to the position, the position and angle of the lattice column 1 are calibrated and the turntable 4 is fixed by braking, which restricts the turntable 4 from continuing to rotate. The brake includes a guide rod 81 and a magnetic plate 82. A fixed seat is provided on the upper side of the positioning platform 2. The guide rod 81 is slidably connected to the fixed seat. One end of the guide rod 81 is fixedly connected to the magnetic plate 82. The guide rod 81 restricts the sliding trajectory of the magnetic plate 82 and facilitates manual pulling of the magnetic plate 82. The magnetic plate 82 is arc-shaped and fits the outer contour of the turntable 4. The magnetic plate 82 and the turntable 4 are in contact by magnetic attraction. After magnetic attraction, the rotation of the turntable 4 is restricted.

[0025] To address the difficulty in controlling the misalignment and angular deviation of the lattice column 1, a positioning platform 2 is installed, and a rotatable turntable 4 is set up to control the rotation angle of the lattice column 1. The turntable 4 and the hydraulic cylinder 5 are used to push forward to accurately position the lattice column 1. The turntable 4 restricts rotation through a brake, stably supports and fixes the lattice column 1, and improves the pass rate of the inspection indicators of the plane position and rotation angle of the lattice column 1.

[0026] The positioner ensures the average force on the upper support, making the connection angle of the steel tie beam more precise, reducing the number of steel reinforcement interruptions in slab structures, greatly improving the overall appearance of the project during the excavation stage, and laying a good foundation for the subsequent construction of the tie beam.
