All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] Embodiment 1
[0025] See also Figures 1 to 4 The utility model provides a technical solution: a building formwork fastening device, comprising a connecting handle 1, both ends of the connecting handle 1 are screwed with a screw rod 3, one end of the screw rod 3 is rotatably connected to the surface of a slider 6, the slider 6 is slidably connected to a traction plate 15, a limit block 7 is fixed to the top surface of the slider 6, the limit block 7 is slidably connected to the top surface of the traction plate 15, a braking screw 9 is screwed to the top surface of the limit block 7, the bottom end of the braking screw 9 is against the top surface of the traction plate 15, and a fastening clamping plate 11 is fixed to one end of the traction plate 15; the screw rod 3 slides inside the traction plate 15 to adjust the length of the screw rod 3 extending out of the traction plate 15 to adapt to support formworks of different widths, and the screw rod 3 is retracted into the inside of the connecting handle 1 by rotating the screw rod 3 to achieve fine adjustment of the clamping force of the two sets of fastening clamping plates 11 clamping the support formwork; it further solves the problem of limited adaptation caused by the fixed size of the existing building formwork fastening device; it can be used when installing and fixing support formworks of different widths.
[0026] Embodiment 2
[0027] See attached Figure 5 On the basis of the first embodiment, in order to adjust the length of the screw rod 3 extending out of the traction plate 15 and then limit it, a slide groove 8 is opened on the top plate of the traction plate 15, and the limit block 7 is slidably connected to the inside of the slide groove 8. The limit block 7 is a "T"-shaped plate structure, and the length of the long side of the top surface of the limit block 7 is greater than the width of the slide groove 8. The brake screw 9 passes through the top plate of the limit block 7 and clamps the rubber gasket 10, and the rubber gasket 10 is fixed to the top surface of the traction plate 15.
[0028] When it is necessary to adjust the length of the screw 3 extending into the traction plate 15, first loosen the brake screw 9, and the brake screw 9 no longer clamps the rubber gasket 10. At this time, pulling out the screw 3 can drive the slider 6 to slide in the traction plate 15. Since the sliding of the limit block 7 is restricted in the slide groove 8, the screw 3 is prevented from being completely withdrawn from the traction plate 15. After determining the length of the screw 3 extending out of the traction plate 15, screw the brake screw 9 downward to clamp the rubber gasket 10, thereby braking the limit block 7. In this way, the screw 3 is braked. The length of the screw 3 extending out of the traction plate 15 is adjusted to achieve that the spacing between the two fastening clamps 11 is equal to the spacing between the support templates on both sides, thereby achieving the fastening clamps 11 clamping the support template.
[0029] Embodiment 3
[0030] See attached Figure 6 and Figure 7 On the basis of the second embodiment, in order to fine-tune the length of the screw rod 3 extending into the screw hole 2 and to meet the requirement that the two fastening clamps 11 tightly clamp the supporting formwork on both sides, a screw hole 2 is provided on the surface of the connecting handle 1, a handle 14 is fixed to one side of the connecting handle 1, and a limited rotation groove 5 is provided on the surface of the slider 6. The limited rotation groove 5 is a "convex" shaped circular groove, and a rotating connecting block 4 is connected to the internal rotation of the limited rotation groove 5. The rotating connecting block 4 is a "convex" shaped circular block, and one end of the rotating connecting block 4 is fixed to one end of the screw rod 3 extending into the traction plate 15. The traction plate 15 is a square frame structure, and a stopper 12 is fixed to the inner ring mouth of one end of the traction plate 15. The stopper 12 is an annular plate structure, and the inner ring mouth of the stopper 12 is a circular mouth structure, and the screw rod 3 passes through the inner ring mouth of the stopper 12.
[0031] After the two fastening clamps 11 pre-clamp the support formwork on both sides, in order to improve the clamping firmness, hold the handle 14 with one hand and the handle 13 with the other hand, turn the handle 13 to drive the screw 3 to rotate and retract into the screw hole 2, one end of the screw 3 drives the rotating connecting block 4 to rotate in the limiting groove 5, and the slider 6 is braked on the traction plate 15, so when the screw 3 moves into the screw hole 2, the traction plate 15 pulls the fastening clamp 11 to clamp the support formwork more tightly.
[0032] In actual use, when it is necessary to adjust the length of the screw rod 3 extending into the interior of the traction plate 15, first loosen the brake screw rod 9, and the brake screw rod 9 no longer clamps the rubber gasket 10. At this time, pulling out the screw rod 3 can drive the slider 6 to slide in the traction plate 15. Since the sliding of the limit block 7 is restricted in the slide groove 8, the screw rod 3 is prevented from being completely withdrawn from the traction plate 15. After determining the length of the screw rod 3 extending out of the traction plate 15, the brake screw rod 9 is screwed downward to clamp the rubber gasket 10, thereby braking the limit block 7. In this way, the screw rod 3 is braked and the length of the screw rod 3 extending out of the traction plate 15 is adjusted to achieve The spacing between the two fastening clamps 11 is equal to the spacing between the supporting formworks on both sides, so that the fastening clamps 11 can clamp the supporting formworks; after the two fastening clamps 11 pre-clamp the supporting formworks on both sides, in order to improve the clamping firmness, one hand holds the handle 14 and the other hand holds the handle 13, and the handle 13 is turned to drive the screw 3 to rotate and retract into the screw hole 2. One end of the screw 3 drives the rotating connecting block 4 to rotate in the limiting groove 5, and the slider 6 is braked on the traction plate 15. Therefore, when the screw 3 moves into the screw hole 2, the traction plate 15 pulls the fastening clamp 11 to clamp the supporting formwork more tightly.
