Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a template rapid reinforcement and pulling device. Background Art

[0002] In the process of construction, construction formwork reinforcement and tensioning devices are often used, especially at the ends of shear walls (shear walls are also called wind-resistant walls, earthquake-resistant walls or structural walls. They are walls in houses or structures that mainly bear horizontal and vertical loads caused by wind loads or earthquakes to prevent structural shear damage. They are generally made of reinforced concrete). The fixation is particularly important for the forming quality of the wall.

[0003] Existing formwork reinforcement tensioning devices usually use long tensioning bolts and steel pipes for fixing and tightening. Although the formwork can be tensioned and reinforced, tensioning screws and short steel pipes need to be specially made, and short steel pipes need to be cut and welded, which easily wastes materials and has high costs. As the length of the screw increases, it is easy to cause poor fastening effect and looseness, which is not conducive to the vertical stability of the construction formwork relative to the horizontal plane, and the molding quality of the wall end needs to be improved.

[0005] In view of the deficiencies in the prior art, the utility model provides a template rapid reinforcement and pulling device, which solves the technical problems that the existing device is expensive to use and the wall end molding quality of the existing device after use needs to be improved.

[0006] (II) Technical solution

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A template rapid reinforcement and tensioning device comprises a turnbuckle bolt, wherein a screw rod is threadably mounted on a side wall of the turnbuckle bolt away from a hook;

[0009] The circumferential thread of the screw rod is provided with a pulling mechanism;

[0020] Wherein, the nut is located between the steel pipe and the limiting ring.

[0021] (III) Beneficial effects

[0027] The embodiment of the present application provides a formwork rapid reinforcement and pulling device, which effectively solves the technical problems that the existing device is expensive to use and the quality of wall end forming after use needs to be improved. By optimizing the structure and layout of the device, adopting a modular design and utilizing threaded installation, the overall structure is relatively simple, the cost is low, and installation and disassembly are convenient. By changing the thread direction of the screw, the length of the hook and the screw on the basket bolt can be quickly adjusted by rotating the basket bolt. Therefore, when the basket bolt is rotated in different directions, the hook and the screw on the basket bolt will move closer or farther away at the same time, and drive the matching steel pipe to pull, which further improves the quality of the end after forming and is more convenient to use. In addition, by rotating the nut, the butterfly card can be driven to perform fine-tuning and correction, which is convenient to use.

[0028] Example

[0029] like Figure 1 As shown, the technical solution in the embodiment of the present application effectively solves the technical problems that the existing device has high cost of use and the quality of the wall end molding of the existing device after use needs to be improved. The overall idea is as follows:

[0030] In view of the problems existing in the prior art, the utility model provides a template rapid reinforcement and tensioning device, comprising a basket bolt 11, and a screw rod 12 is threadedly installed on a side wall of the basket bolt 11 away from the hook;

[0031] The screw rod 12 is provided with a pulling mechanism on the circumferential thread;

[0032] The pulling mechanism includes a nut 13, which is located on a side of the screw 12 away from the basket bolt 11. The pulling mechanism also includes a butterfly clip 14 and a steel pipe 15. The butterfly clip 14 is located on the side wall of the nut 13, and the butterfly clip 14 is located on the circumferential surface of the screw 12. The butterfly clip 14 is fixedly installed with the screw 12, and the butterfly clip 14 is threadedly installed with the nut 13. By changing the thread direction of the screw 12, the basket bolt 11 can be rotated to quickly adjust the length of the hook on the basket bolt 11 and the screw 12. When the basket bolt 11 is rotated in different directions, the hook on the basket bolt 11 and the screw 12 will be close to or away from each other at the same time, and drive the matching steel pipe 15 to pull, which further improves the quality of the end after forming and is more convenient to use. In addition, by rotating the nut 13, the butterfly clip 14 can be driven to perform fine-tuning and correction, which is convenient to use.

[0033] The two steel pipes 15 are both compatible with the butterfly clamp 14, the screw 12 is located between the steel pipes 15, the butterfly clamp 14 is located between the nut 13 and the steel pipe 15, and the two steel pipes 15 are both located between the nut 13 and the basket bolt 11. The pulling mechanism also includes a limit ring 16, which is located on the side wall of the screw 12. The limit ring 16 and the screw 12 are threadedly installed. The limit ring 16 is located at the end of the basket bolt 11, and the limit ring 16 and the nut 13 are on the same side. The nut 13 is located between the steel pipe 15 and the limit ring 16. By optimizing the structure and layout of the device, adopting a modular design and using threaded installation, the overall structure is relatively simple, the cost is low, and it is convenient to install and disassemble.

[0034] Working principle:

[0035] The first step is to take out the screw rod 12 when it is needed, and then install the nut 13 and the butterfly card 14 on the circumferential surface of the butterfly card 14. At this time, the nut 13 will enter the screw rod 12 with the butterfly card 14, and then the basket bolt 11 can be installed on one side of the screw rod 12. When the screw 12 is installed, the butterfly card 14 can be installed at the end away from the basket bolt 11 for position fixing, and then the steel pipe 15 can be installed on the upper and lower sides of the butterfly card 14. The matching steel pipe 15 will seal and reinforce the end of the shear wall.

[0036] In the second step, when in use, the length of the hook on the basket bolt 11 and the screw rod 12 can be quickly adjusted by rotating the basket bolt 11. Since the threads on the screw rod 12 and the hook are left-handed and right-handed, when the basket bolt 11 is rotated, the hook and the screw rod 12 on the basket bolt 11 will approach and move away from each other, and when the nut 13 is rotated, the position of the steel pipe 15 can be fine-tuned.

[0037] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
