[0026] In an exemplary embodiment of the present disclosure, an adjustable beam formwork reinforcement device is provided, as Figure 1 shown, Figure 1 is a schematic structural diagram of an adjustable beam formwork reinforcement device shown according to an exemplary embodiment; Figure 2 is according to an exemplary embodiment shown Figure 1 in which is an enlarged view of part A showing the position of the spring; Figure 3 is according to an exemplary embodiment shown Figure 1 in which is an enlarged view of part B showing the position of the gasket. The following will be explained in conjunction with Figures 1 to 3 for explanation.
[0027] Some specific implementation manners recorded below are intended to facilitate those skilled in the art to understand this embodiment, and this embodiment is not limited by some specific implementation manners recorded below.
[0028] Referring to Figure 1 and Figure 2 , an adjustable beam formwork reinforcement device provided in an exemplary embodiment of the present disclosure, the adjustable beam formwork reinforcement device includes:
[0029] The fixed clamping plate 13 is used to fit against the outer wall of one template and extends from the top end to the bottom end of the template;
[0030] The movable clamping plate 1 is used to fit against the outer wall of the other template and extends from the top end to the bottom end of the template;
[0031] The telescopic rod 2 has a fixed end 23 for driving the fixed clamping plate 13 to fit against the outer wall of the template and a movable end 24 for driving the movable clamping plate 1 to fit against the outer wall of the template;
[0032] The fixator 3 is fixed to either the fixed end 23 or the movable end 24 and extends to the other of the fixed end 23 and the movable end 24. The fixator 3 is used to prevent either the fixed end 23 or the movable end 24 from moving in a direction away from the other of the fixed end 23 and the movable end 24.
[0033] Exemplarily, referring to Figure 1 and Figure 2 , the telescopic rod 2 is in the shape of a long straight rod in a horizontal posture. The fixed end 23 and the movable end 24 are respectively arranged at both ends of the telescopic rod 2. The fixed clamping plate 13 is fixed to the fixed end 23 and extends vertically downward. The movable clamping plate 1 is fixed to the movable end 24 and extends vertically downward. The shortening of the telescopic rod 2 can drive the relative movement of the fixed end 23 and the movable end 24, and the elongation of the telescopic rod 2 can drive the fixed end 23 and the movable end 24 to move away from each other, thereby changing the distance between the fixed clamping plate 13 fixedly connected to the fixed end 23 and the movable clamping plate 1 fixedly connected to the movable end 24. One end of the fixator 3 is fixedly connected to the fixed end 23, and the other end extends to the side of the movable end 24 away from the fixed end 23. The fixator 3 limits the maximum distance of the movable end 24 relative to the fixed end 23 by abutting against the end face of the movable end 24 away from the fixed end 23.
[0034] In this embodiment, by elongating or shortening the telescopic rod 2, the fixed end 23 and the movable end 24 are made to approach or move away from each other, so that the fixed clamping plate 13 and the movable clamping plate 1 respectively adhere to the outer sides of the two templates, and the fixator 3 prevents the movable end 24 from moving away from the fixed end 23, thereby limiting the maximum linear distance between the fixed clamping plate 13 and the movable clamping plate 1, making the maximum opening width of the fixed clamping plate 13 and the movable clamping plate 1 fixed, for limiting the opening size of the template and ensuring the position and posture stability of the template.
[0035] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 2 , the fixator 3 includes a screw 32 fixedly connected to the fixed end 23 and a nut 31 threadedly connected to the screw 32. The nut 31 is used to abut against the end face of the movable end 24 away from the fixed end 23.
[0036] Exemplarily, referring to Figure 1 andFigure 2 One end of the screw rod 32 is fixedly connected to the fixed end 23, and the other end passes through the movable end 24 and extends from the side of the movable end 24 away from the fixed end 23. The nut 31 is threadedly connected to the solid part of the screw rod 32 on the side away from the fixed end 23 from the movable end 24, and can abut the end face of the movable end 24 away from the fixed end 23 by rotating.
[0037] The cam 32 is then rotated to move the movable end 24 away from the fixed end 23 so that the movable end 24 can slide in the direction of the fixed end 23.
[0038] In an exemplary embodiment of the present disclosure, referring to Figure 1 and Figure 2 There are two nuts 31, and a spring 33 is provided between the two nuts 31 for simultaneously abutting the two nuts 31.
[0039] For example, refer to Figure 1 and Figure 2 The two nuts 31 are both located on the screw 32 on the side of the movable end 24 away from the fixed end 23. The spring 33 is sleeved on the screw 32. The two ends of the spring 33 respectively abut against the opposite end faces of the two nuts 31, and the spring 33 is always in a compressed state.
[0040] In this embodiment, the spring 33, which is always in a compressed state, can exert a continuous and stable supporting force on the nut 31, increase the friction between the nut 31 and the screw 32, and reduce the possibility of the nut 31 being rotated by external force, so that the position and posture of the nut 31 remain stable, thereby reducing the possibility that the movable splint 1 and the fixed splint 13 will loosen after the position of the nut 31 changes, causing the position and posture of the template to change.
[0041] In an exemplary embodiment of the present disclosure, referring to Figure 2 and Figure 3, the telescopic rod 2 includes a movable rod 22 and a fixed sleeve 21 sleeved on the movable rod 22. The movable rod 22 has an anti-rotation rib 26 for preventing the fixed end 23 from rotating relative to the movable end 24.
[0042] Exemplarily, referring to Figure 2 and Figure 3 , the movable rod 22 and the fixed sleeve 21 are coaxially arranged, and one end of the movable rod 22 is always located inside one end of the fixed sleeve 21. The end of the movable rod 22 exposed outside the fixed sleeve 21 forms the movable end 24, and the end of the fixed sleeve 21 facing away from the movable rod 22 forms the fixed end 23. The anti-rotation rib 26 is integrally formed on the outer side wall of the movable rod 22. The anti-rotation rib 26 is in the shape of a long straight rod arranged along the length direction of the movable rod 22. The two ends of the anti-rotation rib 26 are located in the area between the movable end 24 and the fixed end 23. A anti-rotation groove 25 adapted to the anti-rotation rib 26 is formed on the side wall of the fixed sleeve 21. The anti-rotation rib 26 is inserted into the anti-rotation groove 25. During the process of the movable rod 22 sliding relative to the fixed sleeve 21, the anti-rotation rib 26 slides along with the movable rod 22 in the anti-rotation groove 25 along the length direction of the movable rod 22.
[0043] In this embodiment, since both the movable rod 22 and the fixed sleeve 21 are cylindrical long straight rod structures, it is easy to generate relative rotation between the movable rod 22 and the fixed sleeve 21, thereby driving the movable clamping plate 1 or the fixed clamping plate 13 to rotate, causing the attitude changes of the movable clamping plate 1 and the fixed clamping plate 13, and reducing the support effect on the template. The setting of the anti-rotation rib 26 can prevent the relative rotation between the movable rod 22 and the fixed sleeve 21, thereby keeping the movable clamping plate 1 and the fixed clamping plate 13 in a stable attitude and exerting a stable and effective clamping effect on the template.
[0044] In an exemplary embodiment of the present disclosure, referring to Figure 2 and Figure 3 , the port of the fixed sleeve 21 has an annular steel brush 27 for abutting against the side wall of the movable rod 22.
[0045] Exemplarily, referring to Figure 2 and Figure 3 , the annular steel brush 27 is fixed at the port of the fixed sleeve 21 facing away from the fixed end 23. The annular steel brush 27 abuts against the outer side wall of the movable rod 22 and shields the gap between the port of the fixed sleeve 21 facing away from the fixed end 23 and the outer wall of the movable rod 22.
[0046] In this embodiment, the annular steel brush 27 can seal the gap between the fixed sleeve 21 and the movable rod 22, and can clean the movable rod 22 during the process of the movable rod 22 sliding relative to the fixed sleeve 21, reducing the possibility of external impurities entering between the fixed sleeve 21 and the movable rod 22 during the concrete pouring process and reducing the possibility of jamming between the movable rod 22 and the fixed sleeve 21.
[0047] In an exemplary embodiment of the present disclosure, refer to Figure 1 and Figure 3 , a gasket 16 is fixedly connected to the movable clamping plate 1 and is flush with the side wall of the fixed sleeve 21.
[0048] Exemplarily, refer to Figure 1 and Figure 3 , the gasket 16 is integrally formed at the top end of the movable clamping plate 1 and abuts against the outer side wall of the movable rod 22, and the bottom surface of the gasket 16 is flush with the outer side wall of the fixed sleeve 21.
[0049] In this embodiment, when in use, the telescopic rod 2 straddles on two templates, and the fixed end 23 and the movable end 24 respectively extend out of the outer sides of the two templates. Since the movable rod 22 is inserted into the fixed sleeve 21, the outer diameter of the fixed sleeve 21 is larger than that of the movable rod 22, that is, the telescopic rod 2 will be in an inclined posture with the movable end 24 below and the fixed end 23 above. At this time, neither the movable clamping plate 1 nor the fixed clamping plate 13 can completely fit the outer side wall of the template. The function of the gasket 16 is to make the telescopic rod 2 straddling on the template in a horizontal posture. No matter where the movable clamping plate 1 moves, the gasket 16 can be pad between the template and the movable rod 22, so that the movable clamping plate 1 and the fixed clamping plate 13 can maintain a vertical posture, and the movable clamping plate 1 and the fixed clamping plate 13 can fit the template, thereby applying a stable and effective clamping force to the template.
[0050] In an exemplary embodiment of the present disclosure, refer to Figure 2 and Figure 3 , both the fixed clamping plate 13 and the movable clamping plate 1 are rotatably connected to the telescopic rod 2, and the rotation axes of the movable clamping plate 1 and the fixed clamping plate 13 are perpendicular to the telescopic rod 2. The telescopic rod 2 is clamped with the fixed clamping plate 13 and the movable clamping plate 1 along the length direction of the telescopic rod 2.
[0051] Exemplarily, refer to Figure 2 and Figure 3 , a fixing ring 15 is integrally formed at the top end of the fixed clamping plate 13. There is a stepped surface extending into the outer wall entity of the fixed sleeve 21 on the outer side wall of the fixed sleeve 21. The fixing ring 15 is coaxially arranged with the fixed sleeve 21 and sleeved on this stepped surface of the fixed sleeve 21. Both ends of the fixing ring 15 are shielded by the outer wall entity of the fixed sleeve 21, and the outer side wall of the fixing ring 15 is coplanar with the outer side wall of the fixed sleeve 21. A movable ring 12 is integrally formed at the top end of the movable clamping plate 1. There is a stepped surface extending into the outer wall entity of the movable rod 22 on the outer side wall of the movable ring 12. The movable ring 12 is coaxially arranged with the movable rod 22 and sleeved on this stepped surface of the movable rod 22. Both ends of the movable ring 12 are shielded by the outer wall entity of the movable rod 22, and the outer side wall of the movable ring 12 is coplanar with the outer side wall of the movable rod 22.
[0052] In this embodiment, through the fixed ring 15 and the movable ring 12, the fixed clamping plate 13 and the movable clamping plate 1 can always maintain a posture of extending vertically downward under the action of gravity, reducing the possibility that the movable clamping plate 1 and the fixed clamping plate 13 deflect as the telescopic rod 2 rotates, so that the fixed clamping plate 13 and the movable clamping plate can exert a stable and effective clamping effect on the template.
[0053] In an exemplary embodiment of the present disclosure, referring to Figure 1 , the fixed clamping plate 13 and the movable clamping plate 1 are triangular with the sharp angles facing away from the telescopic rod 2, and the opposite side walls of the fixed clamping plate 13 and the movable clamping plate 1 have reinforcing ribs.
[0054] Exemplarily, referring to Figure 1 , the fixed clamping plate 13 is parallel to the movable clamping plate 1, and at the same time, both the fixed clamping plate 13 and the movable clamping plate 1 are perpendicular to the telescopic rod 2. A fixed reinforcing rib 14 is integrally formed on the fixed clamping plate 13. The fixed reinforcing rib 14 is located on the side of the fixed clamping plate 13 facing away from the movable clamping plate 1 and protrudes outward. The fixed reinforcing rib 14 extends from the top end to the bottom end of the fixed clamping plate 13. A movable reinforcing rib 11 is integrally formed on the movable clamping plate 1. The movable reinforcing rib 11 is located on the side of the movable clamping plate 1 facing away from the movable clamping plate 1 and protrudes outward. The movable reinforcing rib 11 extends from the top end to the bottom end of the movable clamping plate 1.
[0055] In this embodiment, the fixed reinforcing rib 14 and the movable reinforcing rib 11 can respectively improve the structural strength of the fixed clamping plate 13 and the movable clamping plate 1 laid flat on the template, reduce the possibility that the fixed clamping plate 13 and the movable clamping plate 1 bend after repeatedly clamping the template, reduce the pressure on the template by abutting against the template over a large area, reduce the possibility of damage to the template, and at the same time improve the stability of template clamping.
