Description

Technical Field

[0001] This utility model relates to the field of internal mold technology, and in particular to a template adjustment structure and a template unit with adjustable curvature. Background Technology

[0002] In the construction of hollow concrete structures with curved edges, the curvature of the curved edges of the building's interior cavity changes with the height. Current construction methods involve multiple pours, each forming a separate pouring layer. Each pouring layer requires a separate formwork, meaning the formwork used in the previous pour is unsuitable for the next and cannot be reused. Furthermore, this method requires formwork to be made according to the height of the main structure, meaning the total height of the formwork for all pouring layers is equal to the height of the main structure. All formwork is disposable, consuming a large amount of materials and lacking versatility, resulting in significant waste and high costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a template adjustment structure and a template unit with adjustable curvature that can change the curvature of the inner template to adapt to different curvature cross sections.

[0004] To address the aforementioned problems, this utility model provides a template adjustment structure for adjusting the relative position between the template and a back rib located inside the template along the thickness direction of the template. The structure includes an adjustment part disposed between the template and the back rib located inside the template along the thickness direction of the template, wherein the length of a section of the adjustment part located between the template and the back rib is adjustable.

[0005] Furthermore, the adjustment part includes an adjustment seat, an adjustment rod, and an adjustment member disposed on the inner side of the template. The outer end of the adjustment rod abuts against or is pivotally connected to the adjustment seat, and the inner end of the adjustment rod passes through the back rib. The adjustment member is detachably connected to the adjustment rod along the length direction of the adjustment rod. The adjustment member abuts against the back rib, and the extension length of the outer end of the adjustment rod is adjusted according to the position of the adjustment member on the adjustment rod.

[0006] Furthermore, when the adjusting rod is pivotally connected to the adjusting seat, two adjusting members are detachably connected to the adjusting rod, and the two adjusting members respectively abut against the outer side of the back rib facing the template and the inner side away from the template.

[0007] Furthermore, the adjusting element is an adjusting pin, which is wedge-shaped; the adjusting rod is provided with a plurality of adjusting holes distributed along its length, and the adjusting pin is inserted into the adjusting holes.

[0008] Furthermore, the adjusting rod is provided with multiple rows of adjusting holes distributed along its width direction, and the multiple rows of adjusting holes are staggered along the length direction of the adjusting rod.

[0009] Furthermore, the adjusting element is a nut, the adjusting rod is provided with external threads, and the adjusting element is screwed onto the adjusting rod.

[0010] Furthermore, when the adjusting rod abuts against the adjusting seat, the adjusting seat includes a first seat plate, a second seat plate, and a third seat plate. The upper and lower ends of the third seat plate are respectively fixed to the first seat plate and the second seat plate. The third seat plate, the first seat plate, and the second seat plate form an arc-shaped adjusting groove. The adjusting rod is provided with a ball head that matches the adjusting groove, and the ball head of the adjusting rod is inserted into the adjusting groove.

[0011] Furthermore, the third seat plate is curved into an arc shape, and the adjusting rod is provided with an adapter plate that matches the adjusting groove.

[0012] Furthermore, it also includes an inward adjustment assembly disposed on the template. The inward adjustment assembly includes an adjusting steel band, an adjusting screw, an adjusting nut, and a positioning plate. The adjusting steel band is used to fix it to the template. One end of the adjusting screw is fixed to the adjusting steel band, and the other end of the adjusting screw passes through the positioning plate and is screwed to the adjusting nut. The adjusting nut abuts against the positioning plate, and the positioning plate is used to fix it to the template.

[0013] To solve the above problems, this utility model provides a formwork unit with adjustable curvature. The formwork unit includes a formwork for blocking concrete, a back rib for increasing the strength of the formwork, and the aforementioned formwork adjustment structure for adjusting the curvature of the formwork. The formwork is installed on the back rib.

[0014] This utility model relates to a template adjustment structure and a bend-adjustable template unit. By changing the distance between the adjustment rod and the back rib, the bend of the template can be changed. The adjustment rod is limited by an adjustment component to ensure that it does not move, allowing the template to maintain the corresponding bend. In this way, the template unit equipped with the template adjustment structure can adapt to different cross sections without replacement, and the template can be reused, reducing the number of inner molds that need to be replaced and lowering the cost of the inner mold.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings.

[0028] Example 1

[0029] In this embodiment, when the template 1 is not subjected to external force, the curvature of the template 1 is less than the maximum required curvature, and greater than or less than the required curvature, thus reducing the range of curvature adjustment for the template 1. It should be understood that due to the building's structure, which is wider at the bottom and narrower at the top, the curved edge bends less at the bottom and more at the top; therefore, the curvature adjustment proceeds from small to large.

[0030] like Figures 1 to 3As shown, a preferred embodiment of the adjustable bending template 1 unit of this utility model includes a template 1 for blocking concrete, a back rib 2 installed on the template 1, and a template adjustment structure for adjusting the bending of the template 1. The back rib 2 is used to increase the strength of the template 1. The back rib 2 has a clearance bevel, which provides clearance space when the bending of the template 1 is adjusted, that is, to prevent the template 1 from interfering with the back rib 2 when it contracts inward to adjust the bending. It should be understood that the template 1 can be bent and deformed under external force, and at least a part of the template 1 is arc-shaped, that is, a part of the template 1 can be arc-shaped, or the entire template 1 can be arc-shaped, so that the bending of the template 1 can be adjusted. In this embodiment, the template 1 is arc-shaped. The template adjustment structure includes an adjustment part disposed along the thickness direction of the template 1 between the template 1 and the back rib 2 located inside the template 1, and the length of a section of the adjustment part located between the template 1 and the back rib 2 is adjustable.

[0031] The adjustment unit includes an adjustment rod 3, an adjustment component 4, an adjustment seat 5, and an inward adjustment assembly 6 for increasing the curvature. The adjustment seat 5 is installed on the inner side of the template 1. The outer end of the adjustment rod 3 abuts against the adjustment seat 5, and the inner end of the adjustment rod 3 passes through the back rib 2. The adjustment component 4 is detachably connected to the adjustment rod 3 along its length and abuts against the back rib 2. The extension length of the outer end of the adjustment rod 3 is adjusted according to the position of the adjustment component 4 on the adjustment rod 4; that is, the length of the adjustment rod 3 extending out of the back rib 2 is determined by the position of the adjustment component 4 on the adjustment rod 4. The adjustment component 4 is a pin. The adjustment rod 3 has multiple adjustment holes 31. The adjustment component 4 is inserted into the adjustment holes 31 on the adjustment rod 3, so that the adjustment component 4 abuts against the back rib 2 to limit the length of the adjustment rod 3 inserted into the back rib 2. In other words, the inward adjustment assembly can adjust the distance by which the template 1 is pushed outward. In other embodiments, the adjusting member 4 can also be a nut, and the adjusting rod 3 is provided with external threads, with the nut screwed onto the adjusting rod 3. It should be understood that the adjusting rod 3 can also be pivotally connected to the adjusting seat 5. The inward retraction adjustment assembly 6 includes an adjusting steel strip 61, an adjusting screw 62, an adjusting nut 63, and a positioning plate 64. The adjusting steel strip 61 is fixed to the template 1, one end of the adjusting screw 62 is fixed to the adjusting steel strip 61, and the other end of the adjusting screw 62 passes through the positioning plate 64 and is screwed onto the adjusting nut 63. The positioning plate 64 is fixed to the template 1. Rotating the adjusting nut 63 can move the adjusting screw 62, thereby moving the adjusting steel strip 61 away from or closer to the positioning plate 64. In other words, the inward retraction adjustment assembly 6 can adjust the distance by which the template 1 is pulled inward.

[0032] The back rib 2 has a receiving hole 20. The inner end of the adjusting rod 3 is inserted into the corresponding receiving hole 20 on the back rib 2. There is a gap of 2-3 mm between the receiving hole 20 and the adjusting rod 3 to facilitate adjustment of the position of the adjusting rod 3. The back rib 2 has two baffles 7 to limit the left and right swing of the adjusting rod 3. The baffles 7 and the corresponding back rib 2 are combined to form the receiving hole 20. The adjusting rod 3 is inserted into the receiving hole 20. In other words, the two baffles 7 are located on both sides of the adjusting rod 3 to limit the adjustment rod 3. In other embodiments, a separate plate body can also be provided, and the receiving hole 20 is provided on the plate body.

[0033] like Figure 4 As shown, the adjusting rod 3 is made of plate steel bent into a U-shape, which improves the strength of the adjusting rod 3 and facilitates processing. The adjusting holes 31 on the adjusting rod 3 are arranged in two rows, and the two rows of adjusting holes 31 are staggered. That is, both ends of any adjusting hole 31 overlap with the projection of the two adjacent adjusting holes 31 in the width direction of the other row. This allows the adjusting rod 3 to be inserted into any length of the tapering truss, and the adjusting component 4 can be inserted into the adjusting hole 31, increasing the smoothness of adjustment and enabling stepless adjustment, thus improving versatility. During use, the adjusting holes 31 may be partially blocked by the tapering truss. The unblocked part is defined as the effective hole area, so the size of the effective hole area will change. The adjusting component 4 is set as a wedge shape to accommodate different sizes of effective hole areas. In other embodiments, the number of rows of adjusting holes 31 can be increased or decreased as needed, such as one row, three rows, or more rows.

[0034] like Figure 5 As shown, the adjusting seat 5 is provided with an adjusting groove 50, and the outer end of the adjusting rod 3 is inserted into the adjusting groove 50 to ensure that the adjusting rod 3 will not detach from the adjusting seat 5. Specifically, the adjusting seat 5 includes a first seat plate 51, a second seat plate 52, and a third seat plate 53. The first seat plate 51 and the second seat plate 52 are both fixed on the insertion template 1. The upper and lower ends of the third seat plate 53 are respectively fixed on the first seat plate 51 and the second seat plate 52. The third seat plate 53 is curved into an arc shape. The third seat plate 53, the first seat plate 51, and the second seat plate 52 enclose an arc-shaped adjusting groove 50. The adjusting rod 3 is provided with an adapter plate 32 that is adapted to the adjusting groove 50. The adapter plate 32 of the adjusting rod 3 is inserted into the adjusting groove 50. The arc-shaped adjusting groove 50 can accommodate the adjusting rod 3 from different angles, and has a wide range of adaptability.

[0035] like Figure 6 As shown, in another embodiment, the first seat plate 51 and the second seat plate 52 can also be the crossbeam 21 of the back rib 2, that is, a third seat plate 53 is provided between the two crossbeams 21 to reduce the number of parts.

[0036] Initially, the length of the adjusting rod 3 inserted into the receiving hole is adjusted to the minimum, and the adjusting piece 4 is inserted into the locking hole of the adjusting rod 3 to minimize the curvature of the template 1. The curvature of the template 1 is gradually reduced during subsequent adjustments. When the required curvature of the building structure is less than the initial curvature of the template 1, the inward adjustment component is adjusted by pulling the adjusting piece 4 out of the adjusting hole 31 and then adjusting the length inserted into the receiving hole. After adjustment, the adjusting piece 4 is reinserted to complete the adjustment. At this time, the inward adjustment component 6 does not participate in the adjustment, meaning the adjusting nut 63 is not required. If the adjusting nut 63 is used, it should be adjusted synchronously. When the required curvature of the building structure is greater than the initial curvature of the template 1, the inward adjustment component 6 is adjusted by rotating the nut to pull the adjusting screw 62, which pulls the adjusting steel strip 61. The adjusting steel strip 61 pulls the template 1 inward until the curvature of the template 1 is adjusted to the required value. During this process, the inward adjustment component does not participate in the adjustment, and the adjusting rod 3 and adjusting piece 4 can be removed. If the adjusting rod 3 and adjusting piece 4 are retained, they should be adjusted synchronously.

[0037] The curvature of the template 1 can be adjusted via the adjusting rod 3 and the inward adjustment component 6. This allows the template 1 unit with the template adjustment structure to adapt to different cross-sections without replacement, enabling reuse of the template 1, reducing the number of inner molds that need to be replaced, and lowering the cost of the inner mold. Figure 7 As shown, the problem can be solved by replacing parts of the non-bending template 1 unit, which saves a lot of materials and reduces costs.

[0038] Example 2

[0039] The difference between this embodiment and Embodiment 1 lies in the structure of the security and curvature adjustment mechanism.

[0040] like Figure 8 As shown, the curvature adjustment mechanism includes an adjusting rod 3, an adjusting element 4, and an adjusting seat 5. The adjusting seat 5 is mounted on the corresponding template 1. One end of the adjusting rod 3 is pivotally connected to the adjusting seat 5, and the other end of the adjusting rod 3 passes through the corresponding back rib 2. There are two adjusting elements 4, located on opposite sides of the back rib 2. One adjusting element 4 is located on the outer side of the back rib 2 facing the template 1, and the other adjusting element 4 is located on the inner side facing away from the template. Each adjusting element 4 abuts against the corresponding back rib 2. During adjustment, simply move the adjusting rod 3 and then insert the adjusting element 4 into the corresponding adjusting hole 31.

[0041] Example 3

[0042] In this embodiment, the bending degree of the template 1 is the maximum required bending degree when it is not subjected to external force.

[0043] like Figure 9As shown, the difference between this embodiment and embodiment two is that the structure of the curvature adjustment mechanism is different. Specifically, there is only one adjustment element 4, which is located on the side close to the template 1.

[0044] like Figure 10 As shown, in another embodiment, the initial curvature of the template 1 is the minimum required curvature, and the adjusting member 4 is located on the side away from the template 1.

Any equivalent structure made using the contents of this utility model specification and drawings, whether directly or indirectly applied to other related technical fields, shall also be within the patent protection scope of this utility model.
