Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a liftable steel template climbing cone. Background Art

[0002] Climbing formwork is increasingly used in modern engineering construction. It features easy installation, simple structure, flexible operation, fast construction, and minimal labor. It is a wall-attached climbing formwork construction technology currently widely adopted in the construction industry worldwide. This construction technology is primarily used in high-rise and super-high-rise building shear walls, core tubes, and towering structures in my country's construction projects. It is particularly common in frame core tube structures, and climbing cones are a common support component in climbing formwork systems.

[0003] However, during the concrete pouring process, due to the threaded connection between the screw and the conical nut, the concrete pouring on the screw will cause the screw to rotate relative to the conical nut, causing the connection between the conical nut and the screw to loosen, resulting in an unstable connection between the conical nut and the screw. In severe cases, the screw will separate from the conical nut.

[0004] Therefore, it is necessary to provide a new liftable steel template climbing cone to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a liftable steel formwork climbing cone.

[0006] The utility model provides a liftable steel formwork climbing cone comprising: a screw, a conical nut and an embedded plate, wherein the two ends of the screw are connected to the conical nut and the embedded plate respectively through a threaded structure, and a threaded load-bearing bolt is provided on the side of the conical nut away from the screw;

[0007] Fixedly connected support rings are sleeved on both sides of the outside of the screw, and movably connected extrusion rings are provided on the outside of the two support rings on the back sides thereof. A number of evenly distributed springs are arranged between the extrusion rings and the corresponding support rings, and the outer wall of the extrusion ring is against the end of the corresponding conical nut or embedded plate.

[0008] Preferably, a rotating cylinder is provided in the center of the screw rod, and driving cylinders are provided on both sides of the rotating cylinder with threaded connections through threaded structures, and the thread directions of the threaded structures on both sides are opposite.

[0009] Preferably, the end of the drive cylinder away from the center of the screw is provided with symmetrically distributed protrusions, a sliding rod is inserted between the two protrusions at the end of the same drive cylinder, and an extrusion ring is provided at the end of the sliding rod.

[0010] Preferably, through holes are provided on both sides of the screw rod, and the inner walls of the through holes are abutted against and slidably connected to the outer wall of the sliding rod.

[0011] Preferably, the opposite surfaces of the extrusion rings on both sides are provided with fixedly connected support frames, and the opposite ends of the support frames on both sides extend into the gap between the two extrusion rings.

[0012] Preferably, one end of the spring is fixedly connected to the outer wall of the extrusion ring, and the other end of the spring is fixedly connected to the outer wall of the support ring.

[0013] Compared with the related art, the liftable steel formwork climbing cone provided by the utility model has the following beneficial effects:

[0014] 1. The utility model sets up extrusion rings on both sides of the screw by means of springs. Later, after the screw is connected to the conical nut and the embedded plate, the extrusion rings are squeezed by the springs so that the extrusion rings on both sides respectively abut against the ends of the conical nut and the embedded plate, thereby achieving pressurized fixation of the two, thereby making the connection between the screw, the conical nut and the embedded plate more stable, thereby reducing the loosening of the screw connection during concrete pouring.

[0015] 2. The present invention can also increase the contact area between the screw and concrete during concrete pouring by arranging components such as an extrusion ring on the outside of the screw, thereby improving the firmness of the screw after pouring.

[0016] 3. The utility model adopts the setting of the rotating cylinder. Before the screw is embedded, the driving cylinder and the extrusion ring are driven to move by controlling the rotating cylinder. The extrusion ring and the support frame are squeezed to drive the extrusion ring to move toward the center of the screw. This can reduce the obstruction of the extrusion ring to the installation trajectory of the tapered nut and the embedded plate when they are installed. No additional tools are required for operation, which makes the use and operation of the device more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0025] See also Figures 1 to 5 The embodiment of the utility model provides a liftable steel formwork climbing cone, which includes: a screw rod 1, a conical nut 11 and an embedded plate 12. The two ends of the screw rod 1 are respectively connected to the conical nut 11 and the embedded plate 12 through a threaded structure, and the side of the conical nut 11 away from the screw rod 1 is provided with a threaded force bolt 111.

[0026] In the embodiments of the present invention, please refer to Figures 1 to 5 , both sides of the outside of the screw 1 are provided with fixedly connected support rings 3, and the outsides of the two support rings 3 on the back sides are provided with movably connected extrusion rings 4, and a number of evenly distributed springs 5 ​​are arranged between the extrusion rings 4 and the corresponding support rings 3, and the outer wall of the extrusion ring 4 is against the end of the corresponding conical nut 11 or the embedded plate 12, one end of the spring 5 is fixedly connected to the outer wall of the extrusion ring 4, and the other end of the spring 5 is fixedly connected to the outer wall of the support ring 3.

[0027] It should be noted that: when the conical nut 11 and the embedded plate 12 are screwed and installed in the desired position of the screw 1, the rotating cylinder 2 can be controlled to rotate to drive the extrusion ring 24 to move, so that the extrusion ring 24 releases the extrusion of the support frame 41. At this time, the spring 5 can squeeze the extrusion ring 4 through its own force until the outer wall of the extrusion ring 4 is against the end of the corresponding conical nut 11 or the embedded plate 12. The conical nut 11 and the embedded plate 12 can be pressurized, thereby reducing the phenomenon of the conical nut 11 and the embedded plate 12 rotating at will on the screw 1. Therefore, when the screw 1, the embedded plate 12 and the conical nut 11 are embedded in the screw 1 later, the vibration during the concrete filler can be reduced, causing the conical nut 11, the embedded plate 12 and the screw 1 to become loose and separated, thereby improving the connection stability of the device when embedded.

[0028] In the embodiments of the present invention, please refer to Figures 1 to 5 A rotating cylinder 2 is provided in the center of the screw 1 for rotational connection. Drive cylinders 21 with threaded connections are provided on both sides of the interior of the rotating cylinder 2 through a threaded structure, and the thread directions of the threaded structures on both sides are opposite. The end of the drive cylinder 21 away from the center of the screw 1 is provided with symmetrically distributed protrusions 22. A sliding rod 23 is inserted between the two protrusions 22 at the end of the same drive cylinder 21, and an extrusion ring 24 is provided at the end of the sliding rod 23. Through holes 13 are opened on both sides of the interior of the screw 1, and the inner wall of the through hole 13 is abutted against and slidably connected by the outer wall of the sliding rod 23.

[0029] It should be noted that: through the arrangement of the rotating cylinder 2 and the driving cylinder 21, since the thread directions of the threaded structures connecting the inside of the rotating cylinder 2 and the driving cylinders 21 on both sides are opposite, when the rotating cylinder 2 is controlled to rotate in the later stage, the driving cylinders 21 on both sides can be moved relative to or away from each other, and through the sliding connection between the sliding rod 23 and the through hole 13, during the process of controlling the rotation of the rotating cylinder 2, the driving cylinder 21 can be limited by the abutment between the sliding rod 23 and the inner wall of the through hole 13, which can reduce the synchronous rotation of the driving cylinder 21 with the rotating cylinder 2, and then the rotation of the rotating cylinder 2 can be converted into a force acting on the movement of the driving cylinder 21, so that the driving cylinder 21 can slide stably on the outer wall of the screw 1;

[0030] Therefore, before pre-embedding the screw 1 in the later stage, the rotation of the rotating cylinder 2 can be controlled so that the extrusion ring 24 squeezes the support frame 41 to drive the extrusion ring 4 to move toward the center of the screw 1, thereby reducing the obstruction of the extrusion ring 4 to the installation trajectory of the conical nut 11 and the embedded plate 12 when they are installed, so that the installation of the conical nut 11 and the embedded plate 12 can be smoother. Moreover, since the rotating cylinder 2 is directly mounted on the screw 1, no additional tools are required for operation during use, which makes the use and operation of the device more convenient.

[0031] In the embodiments of the present invention, please refer to Figures 1 to 5 The opposite surfaces of the two extrusion rings 4 are provided with fixedly connected support frames 41, and the opposite ends of the two support frames 41 extend into the gap between the two extrusion rings 24.

[0032] It should be noted that: by extending the support frame 41 into the gap between the two extrusion rings 24, during use, when the conical nut 11 and the embedded plate 12 need to be installed, the two extrusion rings 24 can be controlled to move relative to each other to squeeze the support frame 41 between them, and then the support frame 41 can be used to pull up the extrusion ring 4. Conversely, when the two extrusion rings 24 are controlled to move relative to each other and the extrusion on the support frame 41 is released, the extrusion ring 4 can move in the direction away from the center of the screw 1 under the action of the spring 5, so that the staff can control and adjust the extrusion ring 4 more conveniently in the later stage.

[0033] The working principle of the liftable steel formwork climbing cone provided by the utility model is as follows;

[0034] When using the lifting steel formwork climbing cone, the rotating cylinder 2 can be controlled to rotate first. During the rotation of the rotating cylinder 2, the threaded structure with opposite thread directions on both sides of the internal thread can drive the driving cylinders 21 on both sides to move relative to each other. The relatively moving driving cylinders 21 can squeeze the end of the support frame 41 through the squeezing ring 24, thereby stretching the squeezing ring 4, so that the squeezing rings 4 on both sides of the screw 1 move toward a position close to the center of the screw 1;

[0035] The conical nut 11 and the embedded plate 12 can then be screwed onto the two ends of the screw rod 1 through the threaded structure. When the conical nut 11 and the embedded plate 12 are moved to the desired position, the rotating cylinder 2 can be controlled in the reverse direction to rotate, so that the extrusion ring 24 releases the extrusion of the support frame 41. At this time, the spring 5 located on the support ring 3 can squeeze the extrusion ring 4 through its own force, so that the extrusion ring 4 moves in the direction away from the center of the screw rod 1 until the outer wall of the extrusion ring 4 abuts against the end of the corresponding conical nut 11 or embedded plate 12. The conical nut 11 and the embedded plate 12 can be pressurized, thereby reducing the phenomenon of the conical nut 11 and the embedded plate 12 rotating randomly on the screw rod 1. Therefore, when the screw 1 and the embedded plate 12 are embedded in the conical nut 11 later, the vibration during the concrete filler can be reduced to reduce the loosening and separation between the conical nut 11, the embedded plate 12 and the screw rod 1, thereby improving the pre-embedded connection stability of the device.

[0036] By arranging components such as an extrusion ring 24, an extrusion ring 4 and a spring 5 on the outside of the screw 1, the contact area between the screw 1 and the concrete can be increased when pre-embedded in concrete. Therefore, when the concrete solidifies, the firmness of the pre-embedded device can be improved, thereby improving the support stability of the device for the external lifting steel formwork in the later stage.

[0037] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
