[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-5As shown, a step-by-step tightener for construction includes a support rod 1, a fixing rod 2 is fixedly provided at the rear end of one side of the support rod 1, a tightening structure 3 is arranged inside the support rod 1, the tightening structure 3 includes a screw rod 4, a slider is threadedly installed on the outer wall of the screw rod 4, and connecting plates 6 are fixedly arranged on both sides of the slider, guide grooves 5 are provided on both sides of the support rod 1, a sliding seat 7 is movably provided on the outer wall of the support rod 1, one side of the connecting plate 6 passes through the guide groove 5 and is fixedly connected to the inner wall of the sliding seat 7, a tightening rod 8 is fixedly provided on one side of the sliding seat 7, a reinforcing plate 9 is fixedly provided on the upper end of the sliding seat 7, and a locking knob 10 is threadedly provided on the upper end of the reinforcing plate 9, and an anti-slip plate 11 is fixedly provided on the outer wall of the locking knob 10, and a plurality of clamping holes 12 are provided on the upper end of the support rod 1.

[0023] In this embodiment, the rear end of the fastening rod 8 and the front end of the fixing rod 2 are fixedly provided with anti-skid pads, and the fastening rod 8 and the fixing rod 2 are on the same parallel line. The anti-skid pads are used to stably contact with the casting template.

[0024] In this embodiment, a stabilizing structure 13 is provided inside the fixed rod 2, and the stabilizing structure 13 includes a hidden plate 14. The lower end of the hidden plate 14 is slidably connected to the inner wall of the bottom end of the fixed rod 2. The rear end of the hidden plate 14 is threadedly installed with a screw 16, and the front end of the screw 16 is rotatably connected to a stabilizing plate 17. The hidden plate 14 is used to set the screw 16, and the screw 16 is used to adjust the stabilizing plate 17.

[0025] In this embodiment, the shape of the stabilizing plate 17 is rectangular, and the two sides of the stabilizing plate 17 are in contact with the inner walls of the hidden plate 14, so that the stabilizing plate 17 is in contact with the casting template to increase the contact area.

[0026] In this embodiment, a tightening knob 15 is provided at the upper end of the fixing rod 2 , and the output end of the tightening knob 15 passes through the fixing rod 2 and fits with the upper end of the hidden plate 14 . The tightening knob 15 is used to fix the hidden plate 14 .
