Description

Technical Field

[0001] The utility model relates to the technical field of anchor bolt positioning and fixing, in particular to a positioning and fixing device for embedded anchor bolts of steel pier columns. Background Technique

[0002] In the construction of steel pier columns, the steel pier columns are connected to the bearing platform by embedding multiple anchor bolts. Due to the long free section length of the anchor bolts, during the pouring process of the bearing platform concrete, precise positioning of the embedded anchor bolts is required. If the perpendicularity of the anchor bolts cannot be guaranteed, during the subsequent installation of the steel pier columns, it is impossible to accurately align the anchor bolts with the reserved anchor bolt holes at the column feet of the steel pier columns, resulting in difficult installation. Therefore, how to ensure the relative position of the anchor bolts is very important.

[0003] Currently, in the construction of steel pier columns, the general method for positioning and fixing embedded anchor bolts is to first use angle steel brackets or double-layer steel plates to position and fix the anchor bolts, and then pour concrete. After the concrete is poured and completed, the installation brackets or steel plates cannot be removed, causing waste and greatly increasing the on-site installation cost. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems in the prior art, and a positioning and fixing device for ensuring the positioning and fixing of embedded anchor bolts of multiple steel pier columns and being reusable is proposed.

For example, it can be fixedly connected and set, or detachably connected and set, or integrally connected and set. For those of ordinary skill in the art, the specific meanings of the above terms in this patent can be understood according to specific circumstances.

[0029] Referring to Figures 1-3 , a positioning and fixing device for embedded anchor bolts of a steel pier column, which is applied to the positioning and fixing of embedded anchor bolts of a steel pier column. In order to facilitate the positioning and fixing of multiple embedded anchor bolts and facilitate the installation of the steel pier column.

[0030] The positioning and fixing device for embedded anchor bolts of the steel pier column includes a positioning plate 1 and a plurality of positioning components;

[0031] The positioning plate 1 is in a square frame shape, and each positioning component is arranged at equal intervals along the frame of the positioning plate 1. Each positioning component corresponds to the position of an anchor bolt 10, so that each positioning component positions and fixes an anchor bolt 10. Both sides of the top of the positioning plate 1 are fixedly connected with lifting rings 3, and the lifting rings 3 are provided with lifting holes. The device can be lifted through the lifting rings 3, thus facilitating the repeated use of the device.

[0032] Each positioning component includes a positioning cylinder 2. The positioning cylinder 2 is conical. There are multiple openings provided on the positioning plate 1. Each positioning cylinder 2 is fixedly connected inside an opening. A rubber sleeve 8 is fixedly connected inside the positioning cylinder 2. The inner diameter of the rubber sleeve 8 is consistent with the diameter of the anchor bolt 10. The top end of the anchor bolt 10 can be inserted into the inside of the rubber sleeve 8, so that the rubber sleeves 8 among the positioning components respectively fix the top ends of the respective anchor bolts 10. The rubber sleeve 8 made of rubber can effectively protect the threads at the top end of the anchor bolt 10 and prevent the threads from being damaged, which may cause difficulties in later installation.

[0033] A positioning sleeve 9 is provided at the bottom of the rubber sleeve 8. The bottom diameter of the positioning sleeve 9 is larger than the top diameter, and the top of the positioning sleeve 9 is smoothly connected to the bottom of the rubber sleeve 8. Through the conical positioning sleeve 9, when the device is arranged, the top ends of the respective anchor bolts 10 can pass through the positioning sleeve 9 and be accurately inserted into the corresponding rubber sleeves 8.

[0034] A rubber block 7 is provided at the top of the rubber sleeve 8, and the rubber block 7 is fixedly connected to the inner top end of the positioning cylinder 2. The top end of the anchor bolt 10 can abut against the bottom of the rubber block 7. A through hole 701 is provided in the top of the rubber block 7. A connecting rod 5 is provided inside the through hole 701. The top end and the bottom end of the connecting rod 5 are respectively fixedly connected with a top plate 6 and a moving plate 4. After the anchor bolt 10 is inserted into the rubber sleeve 8, the top end of the anchor bolt 10 can abut against the moving plate 4, so that the connecting rod 5 pushes the top plate 6 to rise and leave the positioning cylinder 2. At this time, the staff can judge whether the anchor bolt 10 is accurately inserted into the rubber sleeve 8 according to the position of the top plate 6, so as to judge whether each anchor bolt 10 is positioned and fixed.

[0035] The positioning sleeve 9 is conical. The outer walls of the rubber block 7, the rubber sleeve 8 and the positioning sleeve 9 are all attached to the inner wall of the conical positioning cylinder 2. So when the device is installed, the rubber block 7, the rubber sleeve 8 and the positioning sleeve 9 are stressed and abut against the conical inner wall of the positioning sleeve 9, making it difficult for the rubber block 7, the rubber sleeve 8 and the positioning sleeve 9 to fall off.

[0036] The working principle of the steel pier column embedded anchor bolt positioning and fixing device: When in use, a hoisting device such as a crane is used to transport the positioning plate 1 through the crane and the lifting ring 3, so that it is transported above each anchor bolt 10, and then the positioning plate 1 is lowered. The top ends of the respective anchor bolts 10 pass through the conical positioning sleeve 9 and are accurately inserted into the corresponding rubber sleeves 8, so that the relative positions of the respective anchor bolts 10 are fixed, thus ensuring the verticality of each anchor bolt 10. And at this time, if the top end of the anchor bolt 10 is inserted into the rubber sleeve 8, the top end of the anchor bolt 10 will push the moving plate 4, so that the connecting rod 5 pushes the top plate 6 to rise and leave the positioning cylinder 2, so as to facilitate the staff to judge whether the anchor bolt 10 is accurately inserted into the rubber sleeve 8 according to the position of the top plate 6, and thus judge whether each anchor bolt 10 is positioned and fixed;

[0037] After the concrete is poured, the positioning plate 1 can be lifted again by a crane and transported to the construction site of another steel pier column to position and fix the anchor bolts of the other steel pier column, which is convenient for the concrete pouring construction.

[0038] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
