Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explanation of the present utility model and is not to be construed as limiting the present utility model, and modifications to the present embodiment, which may not creatively contribute to the present utility model as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present utility model.

Examples: referring to fig. 1, an arc beam formwork support device includes an arc beam 1 having elastic properties, a support plate unit 2 provided at a concave side of the arc beam 1, and a screw unit 3 provided on the arc beam 1 for moving a position of the support plate unit 2. The screw rod unit 3 is rotated to adjust the position of the supporting plate unit 2 in the inner arc of the arc beam 1, and as the whole length of the supporting plate unit 2 is kept unchanged, when the supporting plate unit 2 is closer to the top end of the inner arc of the arc beam 1, referring to fig. 2, the arc beam 1 can be opened through supporting effect, the radian is reduced, and when the arc beam reversely descends, the radian is enlarged due to the elastic property of the arc beam 1, so that different use requirements are met. When leaving the factory, the radian of the arc-shaped beam 1 is generally larger, so that the arc-shaped beam can reset by means of self elastic force.

The screw unit 3 adjusts the position of the support plate unit 2 by: referring to fig. 3, the arc beam 1 includes an elastic plate 101, and a circular groove portion 102 provided on the elastic plate 101 for mounting the screw unit 3; the support plate unit 2 includes a support plate 201, and an internally threaded hole 202 provided on the support plate 201; the screw unit 3 includes a screw post 301 screwed to the internally threaded hole 202, a rotation post portion 302 provided at an upper end of the screw post 301 and installed in the circular groove portion 102, and an armrest post 303 provided at a lower end of the screw post 301. When the position of the support plate unit 2 needs to be adjusted, the armrest column 303 is rotated at the lower part, the driven threaded column 301 is rotated, under the condition that the rotation angle of the support plate 201 is not changed, the threaded column 301 drives the support plate 201 to move up and down through the internal threaded hole 202 arranged on the support plate 201, and the rotating column part 302 inserted into the circular groove part 102 enables the relative position between the threaded column 301 and the elastic plate 101 not to be changed, so that the support plate 201 can move relative to the elastic plate 101.

Further, referring to fig. 3, the threaded post 301 is thinner than the rotating post portion 302 and the armrest post 303, and the hole width of the female screw hole 202 is also smaller than the diameters of the rotating post portion 302 and the armrest post 303, so that the adjustment range is always within the length of the threaded post 301 during the position adjustment of the support plate 201, and the adjustment range of the radian of the elastic plate 101 can be defined by adjusting the length of the threaded post 301.

In order to fix the state that the support plate 201 and the elastic plate 101 do not rotate relatively, and the support plate 201 is separated from the state that the support plate 201 jacks up the inner side surface of the elastic plate 101, the arc-shaped beam 1 further comprises an arc-shaped sliding groove 103 for installing the end of the support plate 201. Referring to fig. 4, the design is such that the support plate 201 can only move along the slotting direction of the arc-shaped sliding groove 103, so that the support plate 201 always maintains a state of jacking up the inner side surface of the elastic plate 101 during the movement.

Since the arc-shaped sliding groove 103 is grooved along the elastic plate 101, the inner groove surface thereof is arc-shaped, and for better contact with the end of the support plate 201, referring to fig. 4, the support plate unit 2 further includes a bevel plate 203 provided on the end of the support plate 201 and installed in the arc-shaped sliding groove 103. The outer end of the inclined panel 203 is provided with an arc surface, the arc of which is similar to the arc of the inner groove surface of the arc-shaped sliding groove 103, and the inner groove surface can be well attached in the sliding process, so that the friction phenomenon is reduced.

In order to avoid the uncoupling of the ramp plate 203 from the curved sliding groove 103, with reference to fig. 4-5, the curved beam 1 further comprises a guide groove 104 provided on the curved sliding groove 103; the support plate unit 2 further includes a guide post 204 provided on the inclined plate 203 and mounted in the guide groove 104. The guide posts 204 are always installed in the guide slots 104 during movement of the ramp 203 so that the ramp 203 does not become disjointed from the arcuate slide slot 103.

Referring to fig. 6 to 7, the circular groove part 102 includes a cylindrical groove 102a, and a lower limit plate 102b provided on an inner side surface of the cylindrical groove 102 a; the spin column portion 302 includes a spin column 302a mounted within the cylindrical slot 102a, and a spin limit plate 302b disposed on the spin column 302a above the lower limit plate 102 b. The rotating column 302a is installed in the cylindrical groove 102a by insertion, and the rotation limiting plate 302b is located above the lower limiting plate 102b, so that the rotating column 302a cannot be out of engagement with the cylindrical groove 102a during rotation.

In order that the threaded post 301 cannot be easily rotated by the support plate 201 or other external forces under the normal state, so that the radian of the elastic plate 101 is changed, the circular groove 102 further includes a braking plate 102c disposed in the cylindrical groove 102 a; the spin column portion 302 further includes a lower pressure plate 302c disposed on the spin column 302a for engaging the brake plate 102 c. The side surfaces of the brake plate 102c and the lower pressure plate 302c are only attached under the action of gravity of the support plate 201, so that the threaded column 301 cannot rotate under the action of friction force of the brake plate 102c and the lower pressure plate 302c, when the threaded column 301 needs to be rotated, the lower pressure plate 302c needs to be lifted up against the action of gravity of the support plate 201, and therefore friction force of the brake plate 102c and the lower pressure plate 302c is cancelled, and the threaded column 301 can rotate.

In addition, in order to limit the free movement range of the support plate 201, so that the lower pressure plate 302c does not move too much under external interference, the circular groove 102 further includes an upper limit plate 102d disposed on the inner side surface of the cylindrical groove 102a and above the lower limit plate 102b; the rotation limiting plate 302b is mounted between the lower limiting plate 102b and the upper limiting plate 102 d. Thus, the rotation limiting plate 302b moves within a very small range between the lower limiting plate 102b and the upper limiting plate 102d, so that the movable range of the supporting plate 201 is very small, and the deformation of the elastic plate 101 caused by the movement is negligible.

The circular groove portion 102 further includes a brake groove 102e provided on the brake plate 102c; the rotating column portion 302 further includes a brake column 302d provided on the lower pressure plate 302c and configured to engage the brake groove 102 e. The braking post 302d and the braking groove 102e assist in the friction fixation of the braking plate 102c with the lower pressure plate 302c, so that the fixation effect of the threaded post 301 in the rotational direction is better when the lower pressure plate 302c is not lifted.

Furthermore, wherever possible, the same or similar reference numbers are used in the drawings and the description to refer to the same or like parts or steps. The drawings are presented in simplified form and are not drawn to precise scale. For convenience and clarity only, directional terms, such as top, bottom, left, right, upward, above, below, rear and front, may be used with respect to the accompanying drawings.
