Description

Technical Field

[0001] This utility model belongs to the field of building structure technology, and specifically relates to a wall column base connection device for building structure. Background Technology

[0002] In steel structures, the function of steel-jointed column bases is to transfer the axial force, bending moment, and shear force at the column end to the foundation, so as to firmly connect the superstructure and the foundation together. Steel-jointed column bases are usually classified into exposed, enclosed, embedded, and inserted types. In actual engineering, the type of column base should be selected reasonably according to the internal force of the column base.

[0003] Chinese patent application number 202222038166.5 discloses a quick-connect device for wall and column bases in building structure design, including a base. An electric push rod is fixedly connected to the inner wall of the base. A baffle is fixedly connected to the end of the electric push rod away from the base. A column is fixedly connected to the end of the baffle away from the electric push rod. A limiting hole is formed on the upper surface of the base, and a limiting column is inserted into the limiting hole. A pressure plate is fixedly connected to one end of the limiting column, and a column is fixedly connected to the middle of the pressure plate. When this quick-connect device for wall and column bases in building structure design needs to be installed, the handle is first pulled by hand to unfold the compression spring, allowing the worker to directly insert the column into the base. Then, the electric push rod is activated, which moves the baffle to insert the column into the insertion hole for initial fixation. Releasing the handle then allows the positioning column to reset under the action of the compression spring and directly insert into the positioning tube, limiting the pressure plate.

[0004] The aforementioned patent describes a process where, after the column is inserted into the base, multiple electric push rods are used to initially fix the column. However, this method has a high setup cost, is not very practical, and requires a power supply. Furthermore, after the column is initially fixed, a positioning pin is inserted into the positioning tube to limit the pressure plate. However, this method is not easy to operate, and a separate operator is required to continuously pull the handle before the column is installed, making the structure for fixing the pressure plate impractical.

[0021] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Please see Figure 1-5The present invention provides the following technical solution: a building structure wall column base connection device, including a base 1, a column 2 tightly inserted above the base 1, a pressure plate 3 fixedly connected to the surface of the column 2, the lower part of the pressure plate 3 and the base 1 being fitted together, and a positioning tube 4 symmetrically and fixedly connected above the pressure plate 3, the base 1 and the column 2 being fixedly connected by a convenient fixing component 5, and the positioning tube 4 and the base 1 being fixedly connected by a convenient positioning component 6.

[0024] Specifically, the convenient fixing component 5 includes a fixing rod 51, a pull block 52, a fixing slider 53, a fixing spring 54, and a limiting component 55. The fixing rod 51 is tightly inserted into both sides of the column 2 at one end inside the fixing rod 51. The fixing rod 51 is slidably connected to the base 1. The pull block 52 is fixedly connected to the end of the fixing rod 51 outside the base 1. The fixing slider 53 is fixedly connected to the bottom of the fixing rod 51. The fixing slider 53 is slidably connected to the base 1. The fixing spring 54 is fixedly connected to one side of the fixing slider 53. The limiting component 55 is provided above the end of the fixing rod 51 outside the base 1.

[0025] By adopting the above technical solution, by pulling the fixing rod 51, the fixing rod 51 drives the fixing slider 53 to move and compress the fixing spring 54. When the fixing rod 51 moves to the upper right side of the fixing rod 51 and coincides with the limiting hole and the limiting component 55, the limiting component 55 limits and fixes the fixing rod 51 to prevent it from rebounding. Then, the column 2 is inserted into the base 1. After that, the limiting component 55 releases the limitation on the fixing rod 51, the fixing spring 54 returns to its original position, and drives the fixing rod 51 to be inserted into the fixing hole on one side of the column 2, thereby completing the initial fixation of the column 2.

[0026] Specifically, the limiting component 55 includes a limiting seat 551, a limiting rod 552, a lifting handle 553, and a flexible steel wire 554. The limiting seat 551 is fixedly connected to the upper sides of both sides of the base 1. The limiting rod 552 is tightly inserted into the middle of the limiting seat 551. One end of the limiting rod 552 is slidably connected to the fixed rod 51. The flexible steel wire 554 is fixedly connected to the lower part of the limiting rod 552. The lifting handle 553 is fixedly connected to the upper part of the limiting rod 552. The lifting handle 553 and the limiting seat 551 are in close contact.

[0027] By adopting the above technical solution, when the limiting component 55 is in use, when the fixing rod 51 moves to the limiting hole on the upper right side of the fixing rod 51 and the limiting rod 552 overlaps, the limiting rod 552 is inserted into the limiting hole in the fixing rod 51 to limit and fix the fixing rod 51 and prevent it from rebounding. Then, the column 2 is inserted into the base 1. After that, the limiting rod 552 is removed, the fixing spring 54 is reset, and the fixing rod 51 is driven to be inserted into the fixing hole on one side of the column 2, thereby completing the initial fixation of the column 2. Finally, the limiting rod 552 is inserted into the limiting hole on the upper left side of the fixing rod 51 to strengthen the fixation of the fixing rod 51. Then, the bendable steel wire 554 is bent to prevent the limiting rod 552 and the fixing rod 51 from separating.

[0028] Specifically, the two sides of the column 2 are provided with fixing holes that can be tightly inserted into the fixing rod 51, and the top of the fixing rod 51 is provided with a limiting hole that can be tightly inserted into the limiting rod 552.

[0029] By adopting the above technical solution, the fixing hole facilitates the insertion of the fixing rod 51 to fix the column 2, and the limiting hole facilitates the insertion of the limiting rod 552 to limit the fixing rod 51.

[0030] In this embodiment, when the fixed rod 51 is pulled, the fixed rod 51 moves the fixed slider 53 to compress the fixed spring 54. When the fixed rod 51 moves to the upper right side of the fixed rod 51 and the limiting hole and the limiting component 55 coincide, the limiting rod 552 is inserted into the limiting hole in the fixed rod 51 to limit and fix the fixed rod 51 and prevent it from rebounding. Then the column 2 is inserted into the base 1. After that, the limiting rod 552 is removed, the fixed spring 54 returns to its original position, and the fixed rod 51 is inserted into the fixing hole on one side of the column 2, thus completing the initial fixation of the column 2. Finally, the limiting rod 552 is inserted into the upper left side of the fixed rod 51 to strengthen the fixation of the fixed rod 51. Then the bendable steel wire 554 is bent to prevent the limiting rod 552 and the fixed rod 51 from separating. This device can easily perform the initial fixation of the column 2 when in use. The structure is practical and reduces the installation cost of the device.

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that, specifically, the convenient positioning component 6 includes a positioning post 61, a connecting plate 62, a square insert 63, a threaded rod 64, a fixing plate 65, a pre-tightening washer 66, and a nut 67. The positioning post 61 is inserted into the middle of the positioning tube 4. One end of the positioning post 61 is fixedly connected to the connecting plate 62, and the other end of the positioning post 61 is fixedly connected to the threaded rod 64. The square insert 63 is fixedly connected to the lower side of one side of the connecting plate 62. The fixing plate 65 is sleeved on the surface of the threaded rod 64. The pre-tightening washer 66 is installed on one side of the fixing plate 65. The nut 67 is installed on one side of the convenient positioning component 6, and the nut 67 and the threaded rod 64 are threadedly connected.

[0033] By adopting the above technical solution, after the initial fixing of the column 2 is completed, the positioning column 61 is inserted into the positioning tube 4 by taking the connecting plate 62, so that the side of the connecting plate 62 that moves is in contact with the positioning tube 4. At the same time, the connecting plate 62 will drive the square insert 63 to be inserted into the connecting groove on one side of the base 1. Then, the fixing plate 65 is sleeved on the threaded rod 64, and then the pre-tightening washer 66 is sleeved on the threaded rod 64. Finally, the nut 67 is installed by thread to fix it, thereby completing the fixing between the positioning tube 4 and the base 1.

[0034] Specifically, a groove is provided on the upper side of one side of the base 1 for tight insertion and connection with the square plug 63.

[0035] By adopting the above technical solution, the connecting groove facilitates the insertion of the square insert 63, which, together with the positioning post 61, is inserted into the positioning tube 4 to fix the pressure plate 3 and the base 1.

[0036] In this embodiment, after the initial fixing of the column 2 is completed, the positioning column 61 is inserted into the positioning tube 4 by taking the connecting plate 62, so that the side of the connecting plate 62 that moves is in contact with the positioning tube 4. At the same time, the connecting plate 62 will drive the square insert 63 to be inserted into the connecting groove on one side of the base 1. Then, the fixing plate 65 is sleeved on the threaded rod 64, and then the pre-tightening washer 66 is sleeved on the threaded rod 64. Finally, the nut 67 is installed by thread to fix it, thereby completing the fixing between the positioning tube 4 and the base 1. This allows the device to conveniently position and fix the pressure plate 3 and the base 1 during use.

[0037] The structure and working principle of the base 1, column 2, pressure plate 3 and positioning tube 4 in this utility model have been disclosed in a quick connection device for wall column feet in building structure design disclosed in Chinese patent application No. 202222038166.5. Its working principle is that the column 2 is inserted into the base 1 for fixation, and then the pressure plate 3 is fixed between the base 1 and the column 2.

[0038] The working principle and usage process of this utility model are as follows: In use, the column 2 is inserted into the base 1 and fixed using the convenient fixing component 5. Then, the positioning tube 4 and the convenient positioning component 6 work together to fix the pressure plate 3 and the base 1. When using the convenient fixing component 5, pulling the fixing rod 51 causes the fixing rod 51 to move the fixing slider 53, compressing the fixing spring 54. When the fixing rod 51 moves to the upper right side of the fixing rod 51 and coincides with the limiting hole and limiting component 55, the limiting rod 552 inserts into the limiting hole in the fixing rod 51, limiting and fixing the fixing rod 51 to prevent it from springing back. Then, the column 2 is inserted into the base 1. After that, the limiting rod 552 is removed, the fixing spring 54 returns to its original position, and the fixing rod 51 is inserted into the fixing hole on one side of the column 2, thus completing the initial fixing of the column 2. Finally, the limiting rod 552 is inserted into the base 1. Rod 552 is inserted into the limiting hole on the upper left side of the fixing rod 51 to strengthen the fixing rod 51. Then, the bendable steel wire 554 is bent to prevent the limiting rod 552 and the fixing rod 51 from separating. This allows the device to easily fix the column 2 during use. The structure is practical and reduces the installation cost of the device. When using the convenient positioning component 6, after the column 2 is initially fixed, the positioning post 61 is inserted into the positioning tube 4 by taking the connecting plate 62. This makes the side of the connecting plate 62 that moves fit into the positioning tube 4. At the same time, the connecting plate 62 will drive the square insert block 63 to be inserted into the connecting groove on one side of the base 1. Then, the fixing plate 65 is sleeved on the threaded rod 64. After that, the pre-tightening washer 66 is sleeved on the threaded rod 64. Finally, the nut 67 is installed by thread to fix it, thereby completing the fixation between the positioning tube 4 and the base 1.
