Description

Technical Field

[0001] The utility model belongs to the technical field of pile foundation construction auxiliary tools, and in particular relates to a pile foundation reinforcement cage positioning tool. Background Art

[0002] Pile foundation is the main foundation form for bridges and house buildings, and pile foundation engineering is the controlling and difficult engineering of the project. Usually, when the pile foundation steel cage is installed, the casing should be 20 to 40 cm larger than the designed pile diameter according to the specification requirements. Therefore, the part of the pile foundation steel cage lowered into the casing is not easy to be centered, which greatly affects the quality of the pile foundation. In addition, the staff needs to constantly adjust the pile foundation steel cage during the process of extending the pile foundation steel cage into the casing, which is time-consuming and not conducive to improving the efficiency of pile foundation construction. Utility Model Content

[0003] The utility model aims to provide a pile foundation reinforcement cage positioning tool to solve the problem that the pile foundation reinforcement cage is not easy to be centered when it is lowered into a casing.

[0004] In order to achieve the above-mentioned purpose, the scheme of the utility model is: a pile foundation steel cage positioning tool, including at least three groups of positioning components, each group of positioning components includes a positioning part, a connecting rod and a wall-attached part, the positioning part includes a positioning plate, a casing slot is provided on the positioning plate, the wall-attached part includes a connecting plate and a wall-attached plate, one end of the connecting rod is fixedly connected to the positioning plate, and the other end of the connecting rod is fixedly connected to the connecting plate.

[0005] The working principle and beneficial effects of this solution are as follows: in this solution, more than three groups of positioning components are evenly distributed on the circumference of the casing, the casing grooves on the positioning pieces are for the casing wall to be inserted, and the wall-adhering pieces are in contact with the inner wall of the casing, so that the connecting rod is parallel to the casing axis so that the pile foundation steel cage can fit the outer wall of the connecting rod and be lowered, thereby realizing the centering of the pile foundation steel cage, thereby effectively improving the construction quality of bored piles, reducing the debugging work of the staff, and avoiding rework caused by the pile foundation steel cage not being centered, which not only saves construction costs, but also improves the efficiency of pile foundation construction, and this solution has a simple structure, easy operation, and high positioning accuracy.

[0006] Optionally, a half ring is fixedly connected to the top end of the positioning piece or the connecting rod.

[0007] In this solution, the half-ring design makes it easier for workers to take and place the positioning components.

[0008] Optionally, the positioning portion further comprises a guide piece which is tilted and the lower end of which is located at one end of the positioning piece close to the center of the casing or at one side of the top end of the connecting rod close to the center of the casing.

[0009] In this scheme, the guide plate is set at an angle, and the inner end of the guide plate (the end close to the center of the casing) is the bottom end, and the outer end of the guide plate (the end away from the center of the casing) is the high end. In this way, the guide plate guides the pile foundation steel cage, which helps to lower the pile foundation steel cage in the center.

[0010] Optionally, the positioning part also includes an adjusting screw, an adjusting cylinder and an axial translation rod. A smooth section and a threaded section are provided in the adjusting cylinder. The adjusting screw is threadedly connected to the threaded section. One end of the adjusting screw located in the adjusting cylinder is rotatably connected to the axial translation rod. The axial translation rod is axially slidingly connected to the smooth section. The end of the axial translation rod away from the adjusting screw is fixedly connected to the guide plate.

[0011] In this solution, the adjusting cylinder is fixedly connected to the positioning piece. By rotating the adjusting screw, the adjusting screw drives the axial translation rod to translate along the axial direction of the adjusting cylinder, thereby causing the guide piece to move radially along the casing. In this way, pile foundation reinforcement cages of different diameters can be guided and centered.

[0012] Optionally, the axial translation rod is provided with scale lines.

[0013] In this solution, the scale lines on the axial translation rod are helpful for the staff to quickly adjust the position of the guide piece.

[0014] Optionally, the connecting rod is a steel pipe, and the positioning plate and the connecting plate are both fixedly connected to the outer wall of the steel pipe.

[0015] In this solution, when the connecting rod is a steel pipe, the outer diameter of the steel pipe is relatively large, and the pile foundation reinforcement cage can be lowered along the outer wall of the steel pipe.

[0016] Optionally, the connecting rod is a solid rod, and an extension piece is provided at one end of the positioning piece close to the center of the casing, the extension piece is perpendicular to the positioning piece, and a side wall of the extension piece away from the positioning piece is flush with the outer wall of the connecting rod.

[0017] In this solution, when the connecting rod is a solid rod, the outer diameter of the solid rod is smaller, and the pile foundation reinforcement cage is first lowered along the extension piece and then lowered along the outer wall of the solid rod.

[0018] Optionally, there are two wall-adhering portions, one wall-adhering portion is distributed at the middle of the connecting rod, and the other wall-adhering portion is distributed at the bottom of the connecting rod.

[0019] In this solution, the two wall-adhering parts support the middle and bottom of the connecting rod respectively. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Embodiment 3

[0036] The difference between this embodiment and the second embodiment is that: Figure 4 As shown, in this embodiment, the top of the steel pipe is not welded with a half ring 400; the positioning part 100 also includes a guide piece 103, an adjusting screw 104, an adjusting cylinder 105 and an axial translation rod 106, the guide piece 103 is tilted, and the lower end of the guide piece 103 is located on the side of the top of the steel pipe (connecting rod 200) close to the center of the casing 500, that is, the guide piece 103 is low inside and high outside; the adjusting cylinder 105 is welded to the positioning piece 101 through a steel sheet, and the axial direction of the adjusting cylinder 105 is aligned with the positioning piece 101. The length direction of the position piece 101 is parallel, a smooth section and a threaded section are provided in the adjusting cylinder 105, the adjusting screw 104 is threadedly connected with the threaded section, one end of the adjusting screw 104 located in the adjusting cylinder 105 is rotatably connected with the axial translation rod 106 through a bearing, and the axial translation rod 106 is axially slidably connected to the smooth section, specifically, the smooth section is provided with an axial slide groove 1051, and the axial translation rod 106 is integrally formed with a slide piece 1061 that slides with the axial slide groove 1051. In addition, a scale line is provided on the axial translation rod 106, so that the staff can quickly adjust the position of the guide piece 103 and make the distance between the four guide pieces 103 and the inner wall of the casing 500 the same.

[0037] When in use, the staff will clamp the positioning piece 101 on the tube mouth of the casing 500, and at the same time, the wall-adhering piece 302 contacts the inner wall of the casing 500, thereby supporting the bottom end of the connecting rod 200, so that the steel pipe (connecting rod 200) is parallel to the axis of the casing 500. After the four sets of positioning components are installed, the pile foundation steel cage is lowered. During the lowering process, the pile foundation steel cage gradually becomes concentric with the casing 500 under the guidance of the guide piece 103, and then the pile foundation steel cage is lowered along the outer wall of the steel pipe (connecting rod 200), thereby ensuring that the pile foundation steel cage is lowered in the center, avoiding the pile foundation steel cage from abutting against the positioning piece 101 during the lowering process, thereby ensuring that the pile foundation steel cage is lowered smoothly.

[0038] In addition, in the present embodiment, the staff can adjust the position of the guide piece 103 by rotating the adjusting screw 104. Specifically, the staff rotates the adjusting screw 104, and the adjusting screw 104 drives the axial translation rod 106 to move radially along the casing 500, thereby driving the guide piece 103 to move radially along the casing 500, thereby adjusting the position of the guide piece 103. During the adjustment process, the staff can grasp the moving distance of the guide piece 103 through the scale line on the axial translation rod 106, and ensure that the distance between the guide piece 103 and the inner wall of the casing 500 in each positioning component is equal, thereby ensuring the guiding and positioning function of the guide piece 103.
