Abstract
Description
Technical Field
[0001] This invention relates to the field of concrete column formwork reinforcement technology, and in particular to a quick-release concrete column casting formwork reinforcement device that is quick to assemble and disassemble, reusable, and produces high-quality molding. Background Technology
[0002] With the increasing diversification of modern building structures, steel formwork for concrete columns has been widely used in engineering construction. However, traditional steel formwork systems generally suffer from the following drawbacks:
[0003] (1) The template is prone to warping and deformation, resulting in uneven edges and poor surface flatness of the concrete column after molding;
[0004] (2) The number of reinforcement components is large and the connection nodes are complex, making installation and removal time-consuming and labor-intensive;
[0005] (3) Low turnover rate, steel is prone to rust, wooden formwork is easily damaged, and overall cost is high;
[0006] For point-based foundation groups such as independent short columns and multi-span greenhouse columns, the traditional combination of steel formwork and wooden formwork has extremely low construction efficiency and unsatisfactory reinforcement effect.
[0007] Patent application number CN202110575903.2 relates to a reinforcement buckle structure for concrete rectangular columns in building construction, particularly a foldable reinforcement buckle structure, belonging to the field of building construction. A foldable rectangular column formwork reinforcement buckle structure includes a template and connectors. The template includes a secondary template A, a main template A, a main template B, and a secondary template B, with their ends sequentially hinged. Secondary templates A and B can slide along the length of the main templates A and B. Connectors connect and limit the free ends of secondary templates A and B. The secondary templates A and B, along with the main templates A and B, form a rectangle, with their inner end faces matching the outer surface of the rectangular column template, and their horizontal axes lying on the same plane.
[0008] However, the aforementioned patented technologies suffer from complex structures and unstable fixation. Therefore, developing a concrete column formwork reinforcement device that is easy to install, provides reliable reinforcement, produces excellent results, and can be quickly assembled and disassembled has become an urgent need in the industry. Summary of the Invention
[0009] The purpose of this invention is to provide a quick-release concrete column casting formwork reinforcement device to solve the problems mentioned in the background art.
[0010] (1) How to strengthen a reliable and reusable quick-release concrete column casting formwork reinforcement device to significantly improve the construction efficiency and forming quality of concrete columns.
[0011] To achieve the above objectives, the present invention provides the following technical solution:
[0012] A quick-release concrete column casting formwork reinforcement device;
[0013] It includes a double-sided sleeve, a first bending clamp, and a second bending clamp. The double-sided sleeve includes an integrally formed rear sleeve portion and a right sleeve portion. The first bending clamp includes an integrally formed rear telescopic rod portion and a left fixed rod portion. The rear telescopic rod portion extends into the rear sleeve portion of the double-sided sleeve. The second bending clamp includes an integrally formed right telescopic rod portion and a front fixed rod portion. The right telescopic rod portion extends into the right sleeve portion of the double-sided sleeve. The left fixed rod portion of the first bending clamp and the front fixed rod portion of the second bending clamp are detachably fixed.
[0014] The double-sided sleeve, the first bend clamp, and the second bend clamp fit together and abut tightly against the outer wall of the concrete column formwork.
[0015] Based on the above technical solution, the present invention can be further improved as follows.
[0016] Furthermore, the inner cross-sectional shape of the rear sleeve portion and the right sleeve portion of the double-sided sleeve is square, the outer contour of the rear telescopic rod portion of the first bending clamp matches the inner contour of the rear sleeve portion of the double-sided sleeve, and the outer contour of the right telescopic rod portion of the second bending clamp matches the inner contour of the right sleeve portion of the double-sided sleeve.
[0017] Furthermore, the left side fixing rod of the first bending clamp has several first positioning holes that penetrate its upper and lower end faces, and the several first positioning holes are arranged at intervals along the length of the left side fixing rod.
[0018] The front fixing rod of the second bending clamp has several second positioning holes that penetrate its upper and lower end faces. The several second positioning holes are arranged at intervals along the length of the front fixing rod.
[0019] This quick-release concrete column casting formwork reinforcement device also includes several pins, which pass through the first positioning hole of the first bending clamp and the second positioning hole of the second bending clamp.
[0020] Furthermore, it also includes a first limiting component, which includes a first limiting nut and a first limiting bolt. The first limiting nut is fixedly connected to the inner hole of the rear sleeve portion of the double-sided sleeve, and the first limiting bolt passes through the rear telescopic rod portion of the first bent clamp and then engages with the first limiting nut.
[0021] Furthermore, it also includes a second limiting component, which includes a second limiting nut and a second limiting bolt. The second limiting nut is fixedly connected to the inner hole of the right sleeve portion of the double-sided sleeve, and the second limiting bolt passes through the rear telescopic rod portion of the second bent clamp and engages with the second limiting nut.
[0022] Furthermore, the double-sided sleeve is made of aluminum.
[0023] Furthermore, the front end of the left fixing rod of the first bending clamp has an assembly groove that extends through its left and right end faces. The assembly groove extends to the front end face of the left fixing rod. The right end of the front fixing rod of the second bending clamp can extend into the assembly groove of the left fixing rod of the first bending clamp.
[0024] This quick-release concrete column casting formwork reinforcement device features a simple structure, quick assembly and disassembly, reliable reinforcement, and reusability, significantly improving the construction efficiency and forming quality of concrete columns.
[0025] The first limiting component of this quick-release concrete column casting formwork reinforcement device allows adjustment of the extension length of the first bending clamp by tightening or loosening the first limiting bolt. Similarly, the second limiting component allows adjustment of the extension length of the second bending clamp by tightening or loosening the second limiting bolt. Finally, by simultaneously or separately rotating the first and second limiting bolts, the overall internal cavity size of the device can be reduced or expanded until it tightly abuts against the outer wall of the concrete column formwork, achieving rapid reinforcement; reverse rotation allows for rapid removal.
[0026] The beneficial effects of this quick-release concrete column casting formwork reinforcement device are:
[0027] (1) Installation or removal can be completed by tightening or loosening only two limit bolts and three pins. The reinforcement time of a single column formwork is shortened to 2-3 minutes, which is more than 10 times more efficient than the traditional method.
[0028] (2) The aluminum formwork material has high rigidity and is not easily deformed. With the help of adjustable limit bolts, it ensures that the formwork system is subjected to uniform stress, and the concrete column has straight edges and a flat surface.
[0029] (3) Aluminum components are corrosion resistant, lightweight, and can be reused more than 100 times, significantly reducing overall costs;
[0030] (4) By adjusting the extension length of the telescopic rod and selecting different positioning holes, it can be adapted to concrete column formwork with various cross-sectional sizes such as 200 mm to 600 mm, and is especially suitable for projects with a large number of independent foundation short columns such as multi-span greenhouses, factories, and warehouses.
