Description

Technical Field

[0001] This application relates to the field of construction production, specifically to a formwork height adjustment device, a formwork elevation adjustment structure, and a formwork frame. Background Technology

[0002] Currently, during aluminum formwork installation, there is approximately a 10mm gap between the wall formwork and the ground to accommodate inconsistent ground heights caused by pouring errors. During installation, the wall panels need to be raised to the correct position; this step is called "elevation adjustment." Currently, the common method for elevation adjustment is to insert shims under the wall panels. This method requires tools to raise the wall panels, and the adjustment accuracy depends on the thickness of the shims, often resulting in an error of 2-3mm or more. This makes it difficult to control the elevation accuracy, and the shim insertion is inefficient, negatively impacting pouring quality and speed. Summary of the Invention

[0003] In view of this, it is necessary to provide a template height adjustment device that can improve the accuracy and efficiency of height adjustment, as well as a template height adjustment structure and template frame having the template height adjustment device.

[0004] One embodiment of this application provides a template height adjustment device, including a first corner plate, a second corner plate, a lead screw, and a lead nut. The first corner plate includes a first connecting wall and a second connecting wall connected at an angle. The second corner plate includes a third connecting wall and a fourth connecting wall connected at an angle, the third connecting wall and the fourth connecting wall being perpendicularly connected to the second connecting wall, and the third connecting wall having a through hole. The lead screw passes through the through hole in the third connecting wall. The lead nut is threadedly connected to the lead screw and is located on the side of the third connecting wall opposite to the fourth connecting wall. The outer diameter of the lead nut is larger than the diameter of the through hole to support the third connecting wall.

[0005] In some embodiments, the template height adjustment device further includes a limiting block, which is connected to the end of the lead screw and located on the side of the third connecting wall near the fourth connecting wall. One side of the limiting block contacts the fourth connecting wall to limit the rotation of the lead screw.

[0006] In some embodiments, the template height adjustment device further includes a limiting ring, which is sleeved around the lead screw and located between the limiting block and the third connecting wall to limit the movement distance of the lead screw.

[0007] In some embodiments, the first connecting wall is perpendicular to the second connecting wall, and the third connecting wall is perpendicular to the fourth connecting wall.

[0008] In some embodiments, the first connecting wall has at least two mounting holes.

[0009] In some embodiments, a bearing plate is connected to the bottom of the lead screw, the bearing plate is perpendicular to the lead screw, and the bottom of the bearing plate has a plurality of semi-circular contacts that are in contact with the ground.

[0010] In some embodiments, the support plate is a regular polygon, with multiple semi-circular contacts located at the sharp corners of the regular polygon, and the bottom of the lead screw is connected to the center of the regular polygon.

[0011] In some embodiments, the template height adjustment device further includes a third corner plate, which includes a fifth connecting wall and a sixth connecting wall that are perpendicularly connected. The fifth connecting wall is connected to a side of the second connecting wall that is away from the second corner plate. The sixth connecting wall is parallel to and opposite to the first connecting wall. A gap is formed between the sixth connecting wall and the first connecting wall. The sixth connecting wall has a clearance hole that is coaxial with the mounting hole.

[0012] In one embodiment of this application, a template height adjustment structure is also provided, including a wall template, a base plate, a pin, and the template height adjustment device in any of the above embodiments. The base plate is bent at a right angle and connected to the bottom of the spliced ​​wall templates. The first connecting wall is attached to the side wall where the two wall templates are spliced. The pin passes through the first connecting wall and the side wall where the wall templates are spliced. The bottom end of the screw rod contacts the ground. After twisting the screw nut, the height of the screw nut relative to the screw rod can be adjusted, thereby adjusting the height of the wall template.

[0013] One embodiment of this application also provides a template frame, including the template elevation adjustment structure described above.

[0014] The aforementioned formwork height adjustment device, formwork elevation adjustment structure, and formwork frame simplify the structure and ensure strength through the first and second corner plates. Furthermore, by twisting the screw nuts to raise the wall formwork, the height of the wall formwork can be adjusted at any distance, thereby improving the accuracy and efficiency of elevation adjustment and ultimately enhancing the pouring quality. In addition, the design employed in the aforementioned formwork height adjustment device and structure significantly improves the overall structural strength and resistance to deformation, greatly reducing the unreliability and inaccuracy of elevation adjustment caused by deformation.

The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0048] One embodiment of this application provides a template height adjustment device, including a first corner plate, a second corner plate, a lead screw, and a lead nut. The first corner plate includes a first connecting wall and a second connecting wall that are perpendicularly connected. The second corner plate includes a third connecting wall and a fourth connecting wall that are perpendicularly connected to the second connecting wall. The third connecting wall has a through hole. The lead screw passes through the through hole and is positioned perpendicular to the third connecting wall. The lead nut is threadedly connected to the lead screw and is located on the side of the third connecting wall opposite to the fourth connecting wall. The outer diameter of the lead nut is larger than the diameter of the through hole to support the third connecting wall.

[0049] In one embodiment of this application, a template height adjustment structure is also provided, including a wall template, a base plate, a pin, and the template height adjustment device in any of the above embodiments. The base plate is bent at a right angle and connected to the bottom of the spliced ​​wall templates. The first connecting wall is attached to the side wall where the two wall templates are spliced. The pin passes through the first connecting wall and the side wall where the wall templates are spliced. The bottom end of the screw rod contacts the ground. After twisting the screw nut, the height of the screw nut relative to the screw rod can be adjusted, thereby adjusting the height of the wall template.

[0050] One embodiment of this application also provides a template frame, including the template elevation adjustment structure described above.

[0051] The aforementioned template height adjustment device, template elevation adjustment structure, and template frame simplify the structure and ensure strength through the first and second corner plates. Furthermore, by twisting the screw nut to lift the wall template, the height of the wall template can be adjusted at any distance, thereby improving the accuracy and efficiency of elevation adjustment and thus improving the pouring quality.

[0052] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0053] Please see Figure 1 This application provides a template height adjustment structure 200 and a template height adjustment device 100 in one embodiment. The template height adjustment structure 200 includes a wall template 210, a base plate 220, pins 230, and a template height adjustment device 100. The base plate 220 is bent at a right angle and connected to the bottom of the wall template 210. The template height adjustment device 100 is located on the inner side of the bend in the base plate 220. The template height adjustment device 100 can lift the base plate 220 and drive the wall template 210 to rise, thereby adjusting the height of the wall template 210 to the standard position. The gap between the lifted base plate 220 and the ground is filled with a filler to prevent grout leakage.

[0054] Please see Figures 2 to 6 The template height adjustment device 100 includes a first corner plate 10, a second corner plate 20, a lead rod 30, and a nut 40. The first corner plate 10 includes a first connecting wall 11 and a second connecting wall 12 connected perpendicularly. The second corner plate 20 includes a third connecting wall 21 and a fourth connecting wall 22 connected perpendicularly. Both the third and fourth connecting walls 21 and 22 are vertically connected to the side of the second connecting wall 12 facing away from the first connecting wall 11. The first and second connecting walls 11 and 12 are vertically arranged, the third connecting wall 21 is horizontally arranged, and the fourth connecting wall 22 is vertically arranged. The first connecting wall 11 is used to connect the vertical side walls 211 where two wall templates 210 are joined. The third connecting wall 21 has a through hole 21a through which the lead rod 30 passes and is perpendicular to the third connecting wall 21. The nut 40 is threadedly connected to the lead rod 30 and is located on the side of the third connecting wall 21 facing away from the fourth connecting wall 22, i.e., at the bottom of the third connecting wall 21. The outer diameter of the nut 40 is larger than the diameter of the perforation 21a, so that the top surface of the nut 40 can support the third connecting wall 21, thereby supporting the wall template 210. The bottom of the screw rod 30 contacts the ground. After twisting the nut 40, the nut 40 can adjust its height relative to the screw rod 30, thereby adjusting the height of the wall template 210.

[0055] As an example, the first corner plate 10 and the second corner plate 20 are welded together. The purpose of this structure is to reduce costs and simplify the structure by welding the two corner plates together, thereby improving processing efficiency. Furthermore, the corner plates, due to their angled structure (preferably a right-angled structure), enhance structural strength. For instance, although the third connecting wall 21 provides direct support, the presence of the fourth connecting wall 22 acts as a reinforcing rib, strengthening the structural stability of the third connecting wall 21. Thus, during use, when the third connecting wall 21 is under stress, the reinforcing rib of the fourth connecting wall 22 prevents the third connecting wall 21 from bending relative to the second connecting wall 12, thus avoiding the overall downward movement of the wall formwork 210 and ensuring accurate height adjustment. Furthermore, because the first connecting wall 11 and the second connecting wall 12 are right-angled and vertically positioned, the first connecting wall 11 does not bend or deforms significantly, thereby improving structural strength and ensuring the accuracy and reliability of height adjustment.

[0056] In some embodiments, the template height adjustment device 100 further includes a limiting block 50. The limiting block 50 is connected to the top of the lead screw 30, that is, located above the third connecting wall 21 (on the side closer to the fourth connecting wall 22). One side of the limiting block 50 contacts the fourth connecting wall 22, preventing it from rotating, thereby restricting the rotation of the lead screw 30, so that the height can be adjusted simply by turning the nut 40. Further, in some embodiments, the other side of the limiting block 50 also contacts the second connecting wall 12, giving the limiting block 50 two force points to further ensure that the limiting block 50 does not rotate. Figure 2 As shown, the limiting block 50 is a rectangular plate, and the two adjacent right-angled sides of the limiting block 50 contact the second connecting wall 12 and the fourth connecting wall 22, respectively.

[0057] In some embodiments, the template height adjustment device 100 further includes a limiting ring 60. The limiting ring 60 is sleeved around the lead screw 30. The limiting ring 60 is located between the limiting block 50 and the third connecting wall 21, that is, the limiting ring 60 is above the third connecting wall 21. The limiting ring 60 is used to limit the movement distance of the lead screw 30. When the lead nut 40 gradually rises until the limiting ring 60 contacts the limiting block 50, the lead nut 40 can no longer rotate, thereby playing a limiting role. For ease of use, the limiting ring 60 is integrated with the third connecting wall 21, thereby reducing the number of parts. Due to the integration, the structure can reduce shaking and further improve structural stability.

[0058] In some embodiments, a support plate (not shown) is connected to the bottom end of the lead screw 30. The surface of the support plate is perpendicularly connected to the lead screw 30. The bottom surface of the support plate has multiple semi-circular contacts. The semi-circular contacts are used to contact the ground. The support plate is used to increase the contact area or contact range between the bottom end of the lead screw 30 and the ground, making the overall structure more stable and preventing slippage of the bottom end of the lead screw 30. The semi-circular contacts are used to reduce friction between the bottom surface of the support plate and the ground, making it easier and less strenuous to use.

[0059] In some embodiments, the support plate is a regular polygon with multiple semi-circular contacts located at the apex of the polygon. The bottom of the lead screw 30 is connected to the center of the regular polygon. This structure further enhances stability. As an exemplary example, the support plate is a plate-shaped equilateral triangle or square to facilitate processing and improve production efficiency.

[0060] In some embodiments, the first connecting wall 11 has at least two mounting holes (not shown) for aligning with holes on the side wall 211 of the wall template 210 so as to insert pins 230 and thereby fix the first connecting wall 11 to the side wall 211 of the wall template 210.

[0061] Please see Figure 7 In some embodiments, the template height adjustment device 100 further includes a third corner plate 70. The third corner plate 70 includes a fifth connecting wall 71 and a sixth connecting wall 72 that are perpendicularly connected. The fifth connecting wall 71 is connected to a side of the second connecting wall 12 facing away from the second corner plate 20. The sixth connecting wall 72 is parallel to and opposite to the first connecting wall 11. A gap 70a is formed between the sixth connecting wall 72 and the first connecting wall 11. The sixth connecting wall 72 has a clearance hole (not shown). The clearance hole is coaxial with the mounting hole. The gap 70a is used to accommodate the side walls 211 of two adjacent wall templates 210 that are joined together. A pin 230 extends into the mounting hole and then out of the clearance hole (or extends into the clearance hole and then out of the mounting hole) to fix the template height adjustment device 100 to the wall template 210.

[0062] In some embodiments, the axis of the lead screw 30 is parallel to the sixth connecting wall 72 and the first connecting wall 11, and the vertical distance between the axis of the lead screw 30 and the opposing surfaces of the sixth connecting wall 72 and the first connecting wall 11 is the same, so that the overall force of the template height adjustment device 100 is symmetrical, thereby improving the structural strength.

[0063] In some embodiments, the template height adjustment device 100 further includes a motor (not shown) for driving the nut 40 to rotate, thereby eliminating the need for manual operation and improving ease of use.

[0064] In some embodiments, the pin 230 is integrally formed with the first connecting wall 11, i.e., there is no mounting hole. In some embodiments, the first connecting wall 11 is provided with a protrusion 111 integrally formed therewith, and the pin 230 is provided on the protrusion 111. This eliminates the need for separate pins, thereby reducing the number of parts and making it easier to use. Due to the integral design, the structure can reduce shaking and further improve structural strength. More importantly, the pin 230 is inserted into the hole on the side wall 211 of the wall template 210, so that the force point is on the side wall 211 of the wall template 210. The side wall 211 is vertical. In use, the side wall 211 is subjected to vertical force, the first connecting wall 11 and the second connecting wall 12 are subjected to vertical force, the third connecting wall 21 is subjected to vertical force, and the fourth connecting wall 22 is horizontally set and subjected to the vertical force of the nut 40. However, because the fourth connecting wall 22 is reinforced by the third connecting wall 21, it will not undergo large deformation as in the prior art, which would affect the accuracy of the elevation adjustment (for example, CN215671104U, an aluminum template elevation adjustment device, if the force is too large, the base plate 6 may face the problem of deformation, thus failing to adjust the elevation accurately, which has been proven in practice). The above structural setting ensures the accuracy, reliability and stability of use.

[0065] One embodiment of this application also provides a template frame, which includes a template elevation adjustment structure 200. This template frame is used, for example, in the construction of an entire building; that is, the template frame also includes an overall template structure composed of more wall templates 210 assembled together.

[0066] In use, first connect the wall template 210 and the base plate 220, then fix the first connecting wall 11 to the side wall 211 of the wall template 210 with the pin 230, and then twist the nut 40 to adjust the height of the nut 40, thereby adjusting the height of the wall template 210.

[0067] The aforementioned template height adjustment device 100 and template elevation adjustment structure 200 simplify the structure and ensure strength through the first corner plate 10 and the second corner plate 20. Furthermore, by twisting the screw nut 40 to lift the wall template 210, the height of the wall template 210 can be adjusted at any distance, thereby improving the accuracy and efficiency of elevation adjustment and thus improving the pouring quality.

[0068] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
