[0002] Columns are a relatively common structural form in buildings. In modern buildings, columns are usually formed by pouring with the cooperation of molds. In this process, it is necessary to fix the formwork. The common method is to attach wooden strips outside the formwork and fix each wooden strip with nails. After the column is formed, the wooden strips and the formwork are removed. With the continuous progress of building technology and the increasing requirements of engineering, the traditional fixing method of column formwork has been difficult to meet the needs of modern construction.

[0003] In modern building projects, the sizes and shapes of columns are various, and it is required that the fixing device can flexibly adapt to column formworks of different specifications and sizes. The traditional fixing method often has the problems of fixed size and inconvenient adjustment, and it is difficult to meet the diverse construction needs. Therefore, we need to propose a fixing device for column formwork. Content of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figure 1-4 , the present invention provides a technical solution:

[0022] A fixing device for a column formwork, including a C-shaped plate 1. A side plate 2 is hinged to one side side wall of the C-shaped plate 1 through a hinge. A positioning block 3 is fixedly connected to one side side wall of the side plate 2. A slide block 4 is slidably inserted into the inside of the positioning block 3. A fixed block 5 is fixedly connected to one side side wall of the C-shaped plate 1. One end of the slide block 4 is inserted into the inside of the fixed block 5. A clamping assembly 6 for positioning the slide block 4 is arranged on one side side wall of the fixed block 5. Clamping assemblies 7 for positioning the column formwork are arranged on one side side wall of the side plate 2 and on the three side walls of the C-shaped plate 1. By setting the C-shaped plate 1, the side plate 2 and the clamping assembly 7 to cooperate, the C-shaped plate 1 can be first sleeved outside the column formwork. Through the cooperation of the positioning block 3, the slide block 4, the fixed block 5 and the clamping assembly 6, the side plate 2 and the C-shaped plate 1 are locked and positioned. At this time, by adjusting the clamping assembly 7, the column formwork can be clamped and fixed, and it is applicable to column formworks of different sizes, with the characteristics of convenient adjustment and meeting the diverse construction requirements, which is beneficial to further improving the flexibility of the device;

[0023] The clamping assembly 7 includes a threaded sleeve 701 fixedly embedded in the side wall of the C-shaped plate 1 (side plate 2). A threaded column 702 is threadedly connected to the inside of the threaded sleeve 701. One end of the threaded column 702 is rotatably connected to a clamping plate 703. The other end of the threaded column 702 is fixedly connected to a handwheel 704;

[0024] By adopting the above case, first, the U-shaped plate 1 is clamped on the outer side of the column formwork, and then the side plate 2 is locked and positioned with the U-shaped plate 1 through the clamping assembly 6. By rotating the handwheel 704, the threaded column 702 can be driven to rotate, so as to drive the clamping plate 703 to move forward, thereby realizing the effect of clamping and fixing the column formwork. In addition, by rotating the handwheel 704 in the reverse direction, the clamping plate 703 can be adjusted to a suitable position, so as to be applicable to column formworks of different sizes. It has the characteristics of convenient adjustment and meeting the diverse construction requirements, which is beneficial to further improving the flexibility of the device;

[0025] It also includes two groups of guide rods 705. One ends of the two groups of guide rods 705 are fixedly connected to one side wall of the clamping plate 703. The other ends of the two groups of guide rods 705 penetrate through the U-shaped plate 1 (side plate 2) and are fixedly connected with anti-disengagement parts 706. And the two groups of guide rods 705 are all slidably connected with the U-shaped plate 1 (side plate 2). By setting the cooperation of the guide rods 705 and the anti-disengagement parts 706, it plays a role in limiting the clamping plate 703, making its movement more stable;

[0026] The clamping assembly 6 includes a positioning sleeve 601. The positioning sleeve 601 is fixedly installed on one side wall of the fixed block 5. A locking rod 602 is slidably inserted into the inside of the positioning sleeve 601. One end of the locking rod 602 penetrates through the fixed block 5 and is inserted into the inside of the slider 4. The other end of the locking rod 602 is fixedly connected with a pull plate 603;

[0027] It also includes a return spring 604. One end of the return spring 604 is fixedly connected to one side wall of the pull plate 603. The other end of the return spring 604 is fixedly connected with one end of the positioning sleeve 601. And the return spring 604 is movably sleeved on the outer wall of the locking rod 602;

[0028] Specifically, when it is necessary to lock and position the side plate 2 with the U-shaped plate 1, the side plate 2 can be first covered, and then the slider 4 is pushed to insert it into the inside of the fixed block 5. At the same time, the pull plate 603 is manually pulled, which can drive the locking rod 602 to move. At this time, the return spring 604 is in a stretched state. When the slider 4 is completely inserted into the inside of the fixed block 5, then the pull plate 603 is released, and the return pulling force of the return spring 604 can be used to firmly insert one end of the locking rod 602 into the inside of the slider 4, thereby realizing the effect of locking and positioning the side plate 2 with the U-shaped plate 1;

[0029] A slot 8 adapted to the slider 4 is opened on one side wall of the fixed block 5. One end of the slider 4 is inserted into the inside of the slot 8. By setting the slot 8, it plays a role in limiting the slider 4. A jack 9 adapted to the locking rod 602 is opened on one side wall of the slider 4. One end of the locking rod 602 is inserted into the inside of the jack 9. By setting the jack 9, it plays a role in limiting the locking rod 602;

[0030] Specifically, when the fixing device needs to be removed, the pull plate 603 can be manually pulled to drive the locking rod 602 to move until one end of the locking rod 602 is separated from the insertion hole 9. At this time, the pull block 10 is pulled to drive the slider 4 to move until the slider 4 is separated from the slot 8. Then the side plate 2 is opened, and the mold plate 1 and the side plate 2 can be removed from the column template, which has the characteristics of easy disassembly and recycling.

[0031] One end of the slider 4 is fixedly connected to a pull block 10, one side of the pull block 10 abuts against one side of the positioning block 3, a limit block 11 is sleeved on the outer wall of the slider 4, and the two sides of the limit block 11 abut against the positioning block 3 and the fixed block 5 respectively. By setting the limit block 11, the slider 4 is limited to prevent it from accidentally falling off.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
