Description

Technical Field

[0001] The utility model relates to the technical field of formwork support screws, in particular to an anti - detachment type expansion single - side formwork support screw structure. Background Art

[0002] When supporting formwork in the construction industry, due to the lack of a device for supporting nuts, it is easy to cause the nut to fall off when the screw fixes the formwork and the formwork vibrates during construction. That is, the nut screwed on the screw will loosen and fall off from the rod body of the screw, which is not convenient for fixing two adjacent formworks. For example, as shown in an expansion single - side formwork screw with the Chinese patent application number CN202022179287.2, an expansion fixing component is thread - sleeved on the outer wall of one end of the screw body, and a fastening nut is thread - connected to the other end of the screw body; the expansion fixing component is column - shaped and the cross - sectional area of one end gradually increases towards the other end, and the large - head end of the expansion fixing component is close to the fastening nut.

[0003] However, when the existing expansion screws support formwork, due to the lack of a device for supporting nuts, it is easy to cause the nut to fall off when the screw fixes the formwork and the formwork vibrates during construction. That is, the nut screwed on the screw will loosen and fall off from the rod body of the screw, which is not convenient for fixing two adjacent formworks. Summary of the Utility Model

[0004] To solve the problem that due to the lack of a device for supporting nuts, it is easy to cause the nut to fall off when the screw fixes the formwork and the formwork vibrates during construction.

[0008] Further, the moving component includes a moving ring threadedly connected to the adjusting component for vertical movement, and a hinge rod for hingedly connecting to the supporting component is movably connected to the ring body of the moving ring.

[0009] Further, the supporting component includes a supporting plate movably connected to the screw rod, and a hinge block for hingedly connecting to the hinge rod is fixedly installed at one end of the supporting plate close to the adjusting component.

[0010] Further, the adjusting component includes a threaded rod disposed inside the screw rod for driving the moving ring to move up and down, and guide rods for assisting the moving ring to move up and down are disposed on the front and rear sides of the threaded rod, and the guide rods penetrate through the ring body of the moving ring.

[0011] Further, the driving component includes a handwheel fixedly installed at the top of the threaded rod, an operation plate for driving the handwheel to rotate is fixedly installed at the top of the handwheel, and a locking rod for locking the handwheel is disposed on the plate body of the handwheel, and the locking rod penetrates through the plate body of the handwheel and is threadedly connected to the screw rod.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] By providing a supporting device and a driving device, when it is necessary to support and fix the nut on the screw rod, the locking rod can be unscrewed and removed from the screw rod, so as to release the locking of the handwheel. Then, by driving the handwheel to rotate through the operation plate, the threaded rod can be rotated synchronously. At the same time, when controlling the moving ring to move up and down along the rod body of the threaded rod, the supporting plate can be driven away from the screw rod through the hinge rod, so as to realize the support and fixation of the nut. Thus, when the formwork vibrates, the nut screwed on the screw rod can be prevented from loosening and falling off the rod body of the screw rod under the action of the supporting plate, and the problem of inconvenience in fixing two adjacent formworks due to the falling of the nut can be solved.

[0029] Please refer to Figures 1-5 , the present utility model provides an anti - detachment type expansion single - side formwork screw structure.

[0030] It includes a screw rod 200 passing through the formwork 100 and supporting the formwork 100, and a nut 300. A supporting device 400 for supporting and fixing the nut 300 is arranged inside the screw rod 200, and a driving device 500 for driving the supporting device 400 to support and fix the nut 300 is arranged inside the screw rod 200.

[0031] Receiving cavities for receiving the moving component 410 are opened at the upper and lower ends of the screw rod 200, and a receiving groove for receiving the supporting component 420 is opened on the rod body of the screw rod 200.

[0032] The supporting device 400 includes a moving component 410 arranged inside the screw rod 200 for moving up and down. A supporting component 420 for supporting and fixing the nut 300 is movably connected to the ring body of the moving component 410.

[0033] The moving component 410 includes a moving ring 411 threadedly connected to the adjusting component 520 for moving up and down. An articulated rod 412 for articulating with the supporting component 420 is movably connected to the ring body of the moving ring 411.

[0034] The supporting component 420 includes a support plate 421 movably connected to the screw rod 200. One end of the support plate 421 close to the nut 300 is L - shaped, so that the L - shaped foot at the bottom end of the support plate 421 can be used to support and fix the nut 300. An articulated block 422 for articulating with the articulated rod 412 is fixedly installed at one end of the support plate 421 close to the adjusting component 520. Thus, when it is necessary to support and fix the nut 300 on the screw rod 200, when the driving device 500 controls the moving ring 411 to move up and down along the rod body of the threaded rod 521, the articulated rod 412 can drive the support plate 421 away from the screw rod 200, and the support and fixation of the nut 300 can be achieved. Therefore, when the formwork 100 vibrates, the nut 300 screwed on the screw rod 200 can be prevented from loosening and falling off the rod body of the screw rod 200 under the action of the support plate 421, and thus it is not convenient to fix two adjacent formworks 100.

[0035] The driving device 500 includes an adjusting component 520 disposed within the screw rod 200 for driving the up-and-down movement of the moving component 410. A driving component 510 for driving the rotation of the adjusting component 520 is fixedly installed at the top end of the adjusting component 520.

[0036] The adjusting component 520 includes a threaded rod 521 disposed within the screw rod 200 for driving the up-and-down movement of the moving ring 411. Guide rods 522 for assisting the up-and-down movement of the moving ring 411 are disposed on the front and rear sides of the threaded rod 521, and the guide rods 522 penetrate through the ring body of the moving ring 411, so that when the moving ring 411 rotates along the threaded rod 521, the moving ring 411 can always move up and down along the rod body of the threaded rod 521.

[0037] The driving component 510 includes a handwheel 511 fixedly installed at the top end of the threaded rod 521. An operation board 512 for driving the rotation of the handwheel 511 is fixedly installed at the top end of the handwheel 511. A locking rod 513 for locking the handwheel 511 is disposed on the plate body of the handwheel 511, and the locking rod 513 penetrates through the plate body of the handwheel 511 and is in threaded connection with the top end of the screw rod 200. Thus, when it is necessary to support and fix the nut 300 on the screw rod 200, the locking rod 513 can be unscrewed and removed from the screw rod 200 to release the locking of the handwheel 511. Then, by driving the handwheel 511 to rotate through the operation board 512, the threaded rod 521 can be rotated synchronously. At the same time, when controlling the up-and-down movement of the moving ring 411 along the rod body of the threaded rod 521, the support plate 421 can be driven away from the screw rod 200 through the hinge rod 412, so as to realize the support and fixation of the nut 300. Thus, when the formwork 100 vibrates, the nut 300 screwed on the screw rod 200 can be prevented from being unscrewed and falling off from the rod body of the screw rod 200 under the action of the support plate 421, and it is not convenient to fix two adjacent formworks 100.

[0038] Based on the above content and the drawings, those skilled in the art can understand and implement the present utility model. In addition, any non-creative modifications made by those skilled in the art to the present utility model without creative labor still fall within the protection scope of the present utility model.
