[0026] It should be noted that in the description of the present application, the terms "upper", "lower", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship shown in the drawings, and are only used for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. The formwork body is cylindrical, and unless otherwise specified, the axial direction of the formwork body in the present embodiment is the axial direction of the formwork body, the radial direction is the diameter direction of the formwork body, and the circumferential direction is the direction of the top surface periphery of the formwork body.

[0027] As shown in the figure, the embodiment discloses a fabricated column formwork structure, comprising:

[0028] The formwork body 1 is a cylindrical steel formwork, and the formwork body 1 is circumferentially divided into a plurality of formwork parts 3, the formwork part 3 has a first connecting part 22 and a second connecting part 5, and any two formwork parts 3 are connected by the first connecting part 22 and the second connecting part 5 to form a connection; that is, the first connecting part 22 of the first formwork is connected to the second connecting part 5 of the second formwork, and so on, so as to form a radially closed cylindrical formwork. Compared with the method of using bolts to fasten, the connection through the connecting part can simplify the operation steps, the first connecting part 22 and the second connecting part 5 can be a matching clamping structure, or a sliding groove structure of sliding fit, or a flange and a groove, and direct plug-in clamping can be realized.

[0029] The fixing assembly 2 comprises an operating handle 10 and a clamping rod, the clamping rod is provided at least with two, the two clamping rods are respectively installed at two ends of the length direction of the operating handle 10, the formwork part 3 is provided with a clamping hole 7, and the two clamping rods are respectively inserted into the clamping holes 7 of the adjacent two formwork parts 3 to limit the adjacent two formwork parts 3. In the embodiment, the two adjacent formwork parts 3 are fixed in the plug-in mode, which is simple and efficient, and can simplify the construction steps and improve the construction efficiency.

[0030] In the embodiment, the fixing assembly 2 further comprises a sleeve 11, the sleeve 11 is provided with two, the two sleeves 11 are respectively installed at two ends of the length direction of the operating handle 10, and the clamping rod is installed on the sleeve 11 in a single degree of freedom sliding mode along the length direction of the sleeve 11. The clamping rod is slidingly arranged to realize the length adjustment function, so that the fixing assembly 2 can be applied to formwork bodies 1 of more sizes.

[0031] In the embodiment, the formwork part 3 has a first circumference 4 and a second circumference in the circumferential direction, the first circumference 4 extends outward in the circumferential direction to form the first connecting part 22, and the second circumference is recessed inward in the circumferential direction to form the second connecting part 5. The first connecting part 22 is a cylinder, and the second connecting part 5 is a cylindrical groove matched with the first connecting part 22. The first connecting part 22 and the second connecting part 5 are both arranged through the first circumference 4 and the second circumference, so that the gap leakage can be avoided. The first connecting part 22 is a cylinder, and the second connecting part 5 is a cylindrical groove matched with the first connecting part 22, and the two are connected by sliding insertion, which is more compact and not easy to be separated during pouring concrete. The cylindrical groove is not easy to accumulate dust, and the problem of dirty accumulation causing the groove to be blocked and difficult to install does not occur.

[0032] In the embodiment, the bottom surface of the template part 3 is concave upward to form a bottom groove 9, and the top surface of the template part 3 is extended upward to form a top flange 8, which is adapted to the bottom groove 9. In this way, a plurality of template parts 3 can be installed by stacking them up and down, without the need for customizing special height templates. The template parts 3 can be stacked according to the needs, saving construction costs. At the same time, since the same template parts 3 are spliced and stacked, the assembly is simpler, effectively improving work efficiency.

[0033] In the embodiment, the template part 3 extends radially outward to form a reinforcing rib 6, and the clamping hole 7 is arranged on the reinforcing rib 6. In the embodiment, three reinforcing ribs 6 are arranged, and a plurality of clamping holes 7 are arranged on each reinforcing rib 6. The reinforcing rib 6 can improve the structural strength of the template part 3 itself and prolong the service life. In addition to clamping and fixing the template part 3 with the clamping rod, the clamping hole 7 can also lighten the template part 3 to reduce construction pressure and facilitate assembly.

[0034] In the embodiment, the clamping rod is provided with a limiting end along the length direction, and the limiting end is provided with a limiting plate 20. The sleeve has a mounting channel penetrating along the length direction, and the end of the mounting channel extends radially inward to form a stroke limiting flange 21. The middle part of the sleeve is hinged to the end of the operating handle 10, and the clamping rod is slidingly installed in the mounting channel, and the limiting plate 20 is located in the mounting channel. The stroke limiting flange 21 and the limiting plate 20 realize the sliding limiting of the clamping rod through the size difference, so as to prevent the clamping rod from sliding out of the sleeve.

[0035] In the embodiment, the clamping rods are provided with four, any sleeve is provided with two clamping rods, the clamping rod arranged above the operating handle 10 is an upper clamping rod 12, and the clamping rod arranged below the operating handle 10 is a lower clamping rod 15; that is, two clamping rods are arranged in each sleeve, the clamping rod sliding upward is the upper clamping rod 12, and the clamping rod sliding downward is the lower clamping rod 15. Since the formwork body 1 can be stacked in the axial direction, the four connected formwork bodies 3 can be connected by using one fixing assembly 2, the upper clamping rod 12 limits the two connected formwork bodies 3 located above, and the lower clamping rod 15 limits the two connected formwork bodies 3 located below. Of course, since the reinforcing ribs 6 can be provided with multiple, the upper clamping rod 12 and the lower clamping rod 15 can be respectively inserted into the clamping holes 7 of the reinforcing ribs 6 on the upper and lower sides of the same formwork body 1 to realize double limiting. Since the sleeve is hingedly installed, when the two lower clamping rods are away from each other due to formwork deformation or other reasons, the two upper clamping rods will be close to each other and clamped in the clamping holes 7, after clamping above, the lower part cannot continue to expand outward, so that the fixing of the fixing assembly 2 to the formwork body 3 is more reliable. The clamping rod slidingly arranged is also for better connecting the upper and lower stacked formwork bodies 1, and increases the application range of the fixing assembly 2.

[0036] In the embodiment, the fixing assembly 2 further comprises a limiting clamping tooth 13, which is installed on the upper clamping rod 12 in a manner that can be driven to swing in a vertical plane. The operating handle 10 is provided with a button 14, which is connected to the limiting clamping tooth 13 through a rope connection or multi-link connection. Driving the button 14 to move downward to make the limiting clamping tooth 13 swing downward. In the embodiment, the fixing assembly 2 further comprises a resilient member 19, one end of which is connected to the limiting clamping tooth 13, and the other end is fixed to the upper clamping rod 12. The resilient member 19 has an elastic force acting on the limiting clamping tooth 13, and the limiting clamping tooth 13 can swing upward in the vertical plane under the action of the elastic force. In the embodiment, both ends of the operating handle 10 in the length direction are provided with a hinge shaft 16, and the sleeve 11 is installed on the operating handle 10 through the hinge shaft 16. The hinge shaft 16 is provided with a pulley 17, and the button 14 and the limiting clamping tooth 13 are connected through a connecting rope 18, one end of which is connected to the bottom of the button 14, and the other end is connected to the limiting clamping tooth 13 after winding around the pulley 17. In the embodiment. Since the upper clamping rod 12 needs to be inserted into the upper clamping hole 7, if the upper and lower clamping holes 7 are far apart, it may be out of the clamping hole 7, so the limiting clamping tooth 13 is arranged, so that the upper clamping rod 12 can be clamped on the reinforcing rib 6 to avoid being out of the clamping hole 7. The swing of the limiting clamping tooth 13 is to make it easier to pass through the limiting clamping hole 7. During the insertion process, the limiting clamping tooth 13 swings downward under the extrusion of the hole wall of the clamping hole 7, so as to pass through the clamping hole 7. After passing through the clamping hole 7, the limiting clamping tooth 13 swings upward under the action of the resilient member 19 and restores to the state before insertion. When the upper clamping rod 12 needs to be pulled out, press the button 14, the connecting rope 18 pulls the limiting clamping tooth 13 to swing downward, so as to pass through the clamping hole 7. After passing through the clamping hole 7, the limiting clamping tooth 13 swings upward under the action of the resilient member 19 and restores to the state before pulling out. In the embodiment, the connecting rope 18 is always in a tension state, so the tension rope will exert a downward pulling force on the limiting clamping tooth 13. The resilient member 19 is a spring, which will exert an upward pulling force on the limiting clamping tooth 13. Under the action of the two forces, the limiting clamping tooth 13 is in a balanced state, which limits the swing of the limiting clamping tooth 13. Of course, a limiting structure can also be arranged separately to limit the limiting clamping tooth 13, which can be understood by those skilled in the art, and will not be described here.

[0037] In the embodiment, the operating handle 10 is further provided with a movable slot, which provides space for the swing of the sleeve and limiting, and an avoiding hole is formed on the upper clamping rod 12 to avoid the limiting clamping tooth 13.

[0038] Finally, it is to be explained that the above embodiments are only used to illustrate the technical solutions of the present application but not to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the purpose and scope of the present application, and all of them should be covered in the scope of the claims of the present application.
