Description

Technical Field

[0001] The utility model relates to the technical field of hanging basket anchoring and leveling, in particular to a leveling device with adjustable angles of anchoring points for finishing-rolled threaded steel hanging baskets. Background Art

[0002] During the construction of the main span of a continuous steel / T-shaped bridge, a cantilevered cast-in-place basket is often used to cast the main span box girder. This basket typically uses finely rolled rebar as anchor points, locking it to the main girder.

[0003] In actual engineering, the anchor points of the suspended pouring basket are usually pre-buried with PVC pipes in the previous section to reserve holes for the anchoring of the fine-rolled threaded steel bars in the next stage of the basket. In order to ensure that the concrete is properly stressed, the rails are often placed on the web of the box beam. This means that the anchor points must be located at the chamfered positions of the flange plate and the inner box chamber. If leveling is not performed during installation, the fine-rolled threaded steel bars will inevitably be installed non-vertically and will be subjected to shear forces during use. When installing the fine-rolled threaded steel bars for convenience and ease, most traditional baskets do not directly level them or use steel plates or fixed-angle triangular wedges for support. The angle cannot be accurately adjusted, making the fine-rolled threaded steel bars not vertical and still subject to shear forces to a greater or lesser extent. In this case, if the basket is used improperly, it is very easy for the fine-rolled threaded steel bars to break due to shear, the anchor points will fail, and the basket will overturn.

[0004] As we all know, hanging baskets are often used repeatedly as temporary equipment. Even if the triangular wedges are precisely designed according to the current bridge type, when they are transferred to the next continuous rigid frame bridge, the chamfer angle will be different from that of the previous bridge type due to differences in span and width. At this time, the old triangular wedges may still not be able to be accurately leveled when applied to the new bridge. Utility Model Content

[0005] The purpose of the utility model is to overcome the disadvantage that the existing technology uses triangular wedge blocks to level the anchoring of fine-rolled threaded steel bars, and when applied to bridges with different spans and widths, it cannot adapt to the chamfer angle, resulting in the inability to accurately level the bars. The utility model also provides a leveling device with adjustable angle for the anchoring point of the fine-rolled threaded steel hanging basket.

[0006] The utility model provides a leveling device for adjusting the angle of the anchor point of the finishing rolled threaded steel hanging basket, comprising:

[0007] a first backing plate, wherein an adjusting screw and a through hole are connected to the first backing plate, the adjusting screw and the through hole are spaced apart along a first direction, and the adjusting screw and the first direction of the first backing plate can be arranged at an angle;

[0008] a second pad, the second pad being provided with a strip hole and a connecting hole, the length direction of the strip hole being the second direction, the second pad being hinged to the first pad via a first hinge shaft, the axial direction of the first hinge shaft being the third direction, the first direction and the second direction both being perpendicular to the third direction, the connecting hole being used to correspond to the through hole, the size of the connecting hole in the second direction being smaller than the size of the through hole in the first direction, the through hole and the connecting hole being used to pass through the fine-rolled threaded steel bar of the hanging basket;

[0009] A fixing piece, wherein the adjusting screw can pass through the strip-shaped hole and be fixed by the fixing piece.

[0010] In this solution, the first pad and the second pad are hinged by a first hinge shaft, so that the first pad and the second pad can rotate relative to each other, so that the first pad and the second pad can form different angles;

[0011] After forming different angles, because the second pad is provided with a strip hole, the length direction of the strip hole is the second direction, and the second direction is perpendicular to the axial direction of the first hinge shaft, that is, the third direction. When the first pad and the second pad are relatively rotated to change the position of the adjusting screw in the second direction, the adjusting screw can always correspond to the strip hole.

[0012] The adjusting screw and the first direction of the first pad can be arranged at an angle, the first direction being perpendicular to the axial direction of the first hinge shaft, i.e., the third direction. After the first pad and the second pad are rotated relative to each other, the adjusting screw is made as perpendicular as possible to the second pad, so as to adapt to the relative rotation of the first pad and the second pad, and ensure that the adjusting screw connected to the first pad can pass through the strip hole.

[0013] And it is connected and fixed by fixing parts to ensure that the angle of the first pad does not change. This method enables the first pad to adapt to the chamfered slope, and the second pad can be adjusted to a horizontal plane. The first pad has a through hole, and the length direction of the through hole is the first direction. Then, after the first pad and the second pad are rotated relative to each other, the through hole and the connecting hole can always correspond to each other, and are used to pass the fine-rolled threaded steel bars, and the fine-rolled threaded steel bars can be horizontally fixed by nuts on the side of the second pad facing away from the first pad.

[0014] The leveling device with adjustable angle for the anchoring point of the finished rolled threaded steel hanging basket described in this solution can adapt to more leveling angles and ensure accurate leveling of the anchoring of the finished rolled threaded steel.

[0015] Preferably, the adjusting screw is fixedly connected to the first pad, and the angle between the adjusting screw and the first pad in the first direction is 70°-80°. The fixing part includes a first fixing nut and a second fixing nut located on both sides of the strip hole, and the first fixing nut and the second fixing nut are both used to threadably connect the adjusting screw.

[0016] The adjusting screw is fixedly connected to the first pad, providing greater stability. The angle between the adjusting screw and the first pad in the first direction is 70°-80°, which is suitable for angle adjustment in most bridge projects. The fixing member includes a first fixing nut and a second fixing nut located on either side of the strip-shaped hole, ensuring that the angle between the first and second pads remains unchanged after adjustment.

[0017] Furthermore, the adjusting screw is welded to the first pad, and the connection is more stable.

[0018] Furthermore, the fixing member further includes a first rubber pad and a second rubber pad located on both sides of the strip-shaped hole, and the first rubber pad and the second rubber pad are used to be arranged between the first fixing nut and the second fixing nut.

[0019] After adjusting the angle between the first pad and the second pad, the angle between the adjusting screw and the second pad may not be vertical. The deformation of the first rubber pad and the second rubber pad enables the first fixing nut and the second fixing nut to adapt to the installation, ensuring the stability and safety of the force.

[0020] Preferably, the adjusting screw is hinged to the first backing plate via a second hinge shaft, and the axial direction of the second hinge shaft is the third direction;

[0021] The fixing member includes a first fixing nut and a second fixing nut located on both sides of the strip-shaped hole, and the first fixing nut and the second fixing nut are both used for threaded connection with the adjusting screw.

[0022] The adjusting screw is hinged to the first pad via a second hinge shaft, and the axial direction of the second hinge shaft is a third direction, so that the adjusting screw can rotate. When the relative angle between the first pad and the second pad is adjusted, the angle between the adjusting screw and the first pad in the first direction can be adjusted so that the adjusting screw can always maintain a vertical relationship with the second pad, and then the angle between the first pad and the second pad can be fixed by the first fixing nut and the second fixing nut threads, so that stability and safety can always be guaranteed.

[0023] Furthermore, a first ear plate is provided at a position where the first backing plate is hinged to the adjusting screw in the third direction, the first ear plate is fixedly connected to the first backing plate, the first ear plate has a first hinge hole, and one end of the adjusting screw for hingedly connecting to the first backing plate has a second hinge hole, and the axial directions of the first hinge hole and the second hinge hole are both in the third direction;

[0024] The second hinge shaft includes a screw and a nut. The screw of the second hinge shaft passes through the first hinge hole and the second hinge hole and is secured by the nut of the second hinge shaft. This allows for an adjustable hinge connection between the screw and the first backing plate. The structure is simple, stable, and removable, making it easy to transport and replace damaged parts, while also reducing costs.

[0025] Furthermore, the first ear plate and the first backing plate are welded to ensure a stable connection.

[0026] Preferably, the first backing plate has a rounded corner on the side hinged to the second backing plate, the first backing plate is provided with a third hinge hole on the side hinged to the second backing plate, the second backing plate is provided with a second ear plate on the side hinged to the first backing plate, the third hinge hole has corresponding second ear plates on both sides, the second ear plate has a fourth hinge hole, and the axes of the third hinge hole and the fourth hinge hole are both in the third direction;

[0027] The first hinge shaft comprises a screw and a nut. The screw of the first hinge shaft passes through the third hinge hole and the fourth hinge hole and is fixed by the nut of the first hinge shaft.

[0028] The first pad is hinged to the second pad on a side with rounded corners for easy rotation. On the basis of ensuring the hinge connection between the first pad and the second pad, the first pad is detachable, which is convenient for transportation and replacement of damaged structures, and has lower costs.

[0029] Preferably, the through hole is located in the middle of the first pad in the first direction;

[0030] The connection hole is located in the middle of the second pad in the second direction.

[0031] This makes the connection and fixation of the finished rolled threaded steel bars more stable.

[0032] Preferably, the adjusting screw is arranged on a side of the first pad away from the first hinge shaft in the first direction;

[0033] The strip-shaped hole is located on a side of the second pad away from the first hinge shaft in the second direction.

[0034] This makes the force-bearing performance of the leveling device for adjusting the angle of the anchor point of the finishing-rolled threaded steel hanging basket better.

[0035] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a leveling device for adjusting the angle of the anchor point of a fine-rolled threaded steel hanging basket, wherein a first pad and a second pad are hingedly connected by a first hinge shaft, so that the relative angle between the first pad and the second pad can be changed. The first pad has an adjustment screw, and the second pad has a strip-shaped hole. When the relative angle between the first pad and the second pad is changed, the strip-shaped hole has an adaptability range, so that the adjustment screw can always pass through the strip-shaped hole and be fixed by the fixing member, ensuring that the relative angle between the first pad and the second pad does not change after adjustment. The second pad has a connecting hole, and the first pad has a through hole. When the relative angle between the first pad and the second pad is changed, the through hole has an adaptability range, so that the fine-rolled threaded steel of the hanging basket can always pass through the through hole and the connecting hole and be fixedly connected by the leveling device.

[0056] Example 1

[0057] like Figure 1-11 As shown, a leveling device for adjusting the angle of the anchor point of a finishing-rolled threaded steel hanging basket comprises a first pad 1, a second pad 2 and a fixing member;

[0058] The first pad 1 is connected to an adjusting screw 11 and provided with a through hole 12. The adjusting screw 11 and the through hole 12 are spaced apart along a first direction. The adjusting screw 11 and the first direction of the first pad 1 can be arranged at an angle, which can be a fixed angle, such as Figure 1 As shown, it can also be the adjusted angle, such as Figure 13As shown; In this embodiment, the first pad 1 is a rigid structure, such as a steel plate, which can play a load-bearing role;

[0059] like Figure 4 As shown, the second pad 2 is provided with a strip hole 21 and a connecting hole 22, the length direction of the strip hole 21 is the second direction, and the second direction is Figure 1 and Figure 4 the second pad 2 and the first pad 1 can be hinged by a first hinge shaft 31, the axial direction of the first hinge shaft 31 is the third direction, ie Figure 3 and Figure 4 The first direction and the second direction are both perpendicular to the third direction. The connecting hole 22 is used to correspond to the through hole 12. The size of the connecting hole 22 in the second direction is smaller than the size of the through hole 12 in the first direction. The through hole 12 can be a bar hole or a round hole larger than the connecting hole 22. Figure 4 The through hole 12 and the connecting hole 22 are used to pass the finished rolled threaded steel bar 5 of the hanging basket. Figure 11 As shown;

[0060] The adjusting screw 11 can pass through the strip-shaped hole 21 and be secured by the fixing member. The main purpose of the fixing member is to ensure that the angle between the first pad 1 and the second pad 2 remains unchanged after the relative angle between the first pad 1 and the second pad 2 is adjusted. Therefore, the fixing member can adopt various fixing methods.

[0061] In a first embodiment, if Figures 1-11 As shown, the adjusting screw 11 is fixedly connected to the first pad 1, and the angle between the adjusting screw 11 and the first pad 1 in the first direction is 70°-80°. The fixing member includes a first fixing nut 41 and a second fixing nut 42 located on both sides of the strip hole 21. The first fixing nut 41 and the second fixing nut 42 are both used to thread the adjusting screw 11. Among them, the adjusting screw 11 is fixedly connected to the first pad 1, and has higher stability. The angle between the adjusting screw 11 and the first pad 1 in the first direction is 70°-80°, which can adapt to the angle adjustment of most bridge projects. The fixing member includes a first fixing nut 41 and a second fixing nut 42 located on both sides of the strip hole 21, which can ensure that the angle remains unchanged after adjusting the angle between the first pad 1 and the second pad 2.

[0062] Optional, such as Figure 1 As shown, the adjusting screw 11 is welded to the first pad 1, and the connection is more stable.

[0063] In a second embodiment, if Figure 12As shown, the fixing member further includes a first rubber pad 43 and a second rubber pad 44 located on either side of the strip-shaped hole 21. The first rubber pad 43 and the second rubber pad 44 are configured to be disposed between the first fixing nut 41 and the second fixing nut 42. When the angle between the first backing plate 1 and the second backing plate 2 is adjusted, the angle between the adjustment screw 11 and the second backing plate 2 may not be perpendicular. The deformation of the first rubber pad 43 and the second rubber pad 44 allows the first fixing nut 41 and the second fixing nut 42 to adapt to the installation, ensuring the stability and safety of the force.

[0064] In a third embodiment, as Figure 13 As shown, the adjusting screw 11 is hinged to the first backing plate 1 through the second hinge shaft 32, and the axial direction of the second hinge shaft 32 is the third direction;

[0065] The fixing member includes a first fixing nut 41 and a second fixing nut 42 located on both sides of the strip-shaped hole 21 . The first fixing nut 41 and the second fixing nut 42 are both used for threaded connection with the adjusting screw 11 .

[0066] The adjusting screw 11 is hinged to the first pad 1 via a second hinge shaft 32. The axial direction of the second hinge shaft 32 is in the third direction, allowing the adjusting screw 11 to rotate. When adjusting the relative angle between the first pad 1 and the second pad 2, the angle between the adjusting screw 11 and the first pad 1 in the first direction can be adjusted to ensure that the adjusting screw 11 and the second pad 2 always maintain a perpendicular relationship. The angle between the first pad 1 and the second pad 2 is then fixed by the first fixing nut 41 and the second fixing nut 42, ensuring stability and safety. This method does not require the first rubber pad 43 and the second rubber pad 44.

[0067] Optionally, a first ear plate 111 is provided at a position where the first backing plate 1 is hinged to the adjusting screw 11 in the third direction, the first ear plate 111 is fixedly connected to the first backing plate 1, the first ear plate 111 has a first hinge hole, and one end of the adjusting screw 11 used for hinged connection to the first backing plate 1 is provided with a second hinge hole, and the axial directions of the first hinge hole and the second hinge hole are both in the third direction;

[0068] The second hinge shaft 32 includes a screw and a nut. The screw of the second hinge shaft 32 passes through the first hinge hole and the second hinge hole and is fixed by the nut of the second hinge shaft 32. This can achieve a hinged connection between the adjustment screw 11 and the first backing plate 1, and has a simple structure, high stability, and is detachable, which is convenient for transportation and replacement of damaged structures, and reduces costs.

[0069] Optionally, the first ear plate 111 is welded to the first pad 1 to ensure a stable connection.

[0070] In some embodiments, as Figure 3 and Figure 4 As shown, the first backing plate 1 has a rounded corner on the side hinged to the second backing plate 2, the first backing plate 1 is provided with a third hinge hole 13 on the side hinged to the second backing plate 2, the second backing plate 2 is provided with a second ear plate 23 on the side hinged to the first backing plate 1, both sides of the third hinge hole 13 have corresponding second ear plates 23, the second ear plate 23 has a fourth hinge hole 231, and the axes of the third hinge hole 13 and the fourth hinge hole 231 are both in the third direction;

[0071] The first hinge shaft 31 is a screw and a nut. The screw of the first hinge shaft 31 passes through the third hinge hole 13 and the fourth hinge hole 231 and is fixed by the nut of the first hinge shaft 31 .

[0072] The first pad 1 is hinged to the second pad 2 on a rounded corner for easy rotation. While ensuring the hinge connection between the first pad 1 and the second pad 2, the first pad 1 and the second pad 2 are detachable, which is convenient for transportation and replacement of damaged structures, and has lower costs.

[0073] In some embodiments, as Figures 1-4 As shown, the through hole 12 is located in the middle of the first pad 1 in the first direction; the connecting hole 22 is located in the middle of the second pad 2 in the second direction. This makes the connection and fixation of the finished rolled threaded steel more stable. Figure 11 shown.

[0074] In some embodiments, as Figures 1-4 As shown, the adjusting screw 11 is arranged on the side of the first pad 1 away from the first hinge shaft 31 in the first direction; the strip hole 21 is located on the side of the second pad 2 away from the first hinge shaft 31 in the second direction. This makes the leveling device for the adjustable angle of the finishing threaded steel hanging basket with better force performance, such as Figure 11 shown.

[0075] In the above embodiment, the first pad 1 and the second pad 2 are hinged by the first hinge shaft 31, so that the first pad 1 and the second pad 2 can rotate relative to each other, so that the first pad 1 and the second pad 2 can form different angles; and after forming different angles, because the second pad 2 is provided with a strip hole 21, the length direction of the strip hole 21 is the second direction, and the second direction is perpendicular to the axial direction of the first hinge shaft 31, that is, the third direction, when the first pad 1 and the second pad 2 are relatively rotated to change the position of the adjusting screw 11 in the second direction, the adjusting screw 11 can always correspond to the strip hole 21; and the adjusting screw 11 can be set at an angle to the first direction of the first pad 1, and the first direction is perpendicular to the axial direction of the first hinge shaft 31, that is, the third direction, between the first pad 1 and After the second pad 2 rotates relative to each other, the adjusting screw 11 is made as perpendicular to the second pad 2 as possible, which can adapt to the relative rotation of the first pad 1 and the second pad 2, and ensure that the adjusting screw 11 connected to the first pad 1 can pass through the strip hole 21; and is connected and fixed by a fixing piece to ensure that the angle of the first pad 1 no longer changes. This method enables the first pad 1 to adapt to the chamfered inclined surface, and the second pad 2 can be adjusted to a horizontal plane, and the first pad 1 has a through hole 11, and the length direction of the through hole 12 is the first direction. Then, after the first pad 1 and the second pad 2 rotate relative to each other, the through hole 12 and the connecting hole 22 can always correspond to each other, and are used to penetrate the fine-rolled threaded steel bar, and the fine-rolled threaded steel bar can be horizontally fixed by a nut on the side of the second pad 2 facing away from the first pad 1.

[0076] The leveling device for the adjustable angle of the anchor point of the finished-rolled threaded steel hanging basket is used. The device can adjust the support length of the adjusting screw 11 by turning the position of the first fixing nut 41 and the second fixing nut 42 to achieve the purpose of adjusting the angle and precise leveling. It can adapt to more leveling angles and can ensure the precise leveling of the anchoring of the finished-rolled threaded steel. The leveling device is equivalent to an adjustable angle triangular wedge, which can be finely adjusted according to different chamfer angles to ensure that the finished-rolled threaded steel is vertical during anchoring, so that it is no longer sheared, avoiding its breakage and structural instability. This structure is simple, has high stability and structural strength, high lifting safety, and the steel box girder is not easy to deform.

[0077] The adjusting screw 11 can be a fully open-threaded structure, with the first and second fixing nuts 41, 42 selected based on the adjusting screw 11. The strip-shaped hole 21 can be a rounded hole, with its size and position determined by the adjusting bolt. The fourth hinge hole 231 on the second lug 23 can be adjusted based on the size of the third hinge hole 13 drilled at the front end of the first base plate 1. The first hinge shaft 31 can be connected with a commercially available long bolt based on the size of the third hinge hole 13. The device features a simple design, with bolt-welded connections between components. Materials are readily available, making fabrication and assembly simple. The screws and nuts can be adjusted to accommodate various chamfering angles. After use, the device can be disassembled into three parts for relocation and reuse. Made of conventional steel plates, bolts, and nuts, it can be disassembled into components that can be fabricated in a factory or on-site, making it quick and easy. After disassembly, it can be reassembled and adapted to various continuous rigid / T-beam bridges.

[0078] For the first embodiment, a method for assembling and using the same is also provided. Figures 6-11 As shown, the following steps are included:

[0079] Step 1: After the materials are laid out, drilled, welded, and other operations are performed according to the design drawing, a first backing plate 1, a second backing plate 2, an adjusting screw 11, a first fixing bolt 41, a second fixing bolt 42, and a first hinge shaft 31 are formed. The adjusting screw 11 is connected to the first backing plate 1. The first backing plate 1 has a third hinge hole 13, the second backing plate 2 has a second ear plate 23, and the second ear plate 23 has a fourth hinge hole 231; as shown in FIG. Figure 6 As shown, align the third hinge hole 13 and the fourth hinge hole 231; wherein, two first fixing bolts 41 are provided at intervals in the third direction, and two second ear plates 23 are provided at intervals in the third direction;

[0080] Specifically, the first backing plate 1 measures 205*94*20mm. A ∅58mm circular hole is provided in the center of the plate as a through hole 12 for inserting the finely rolled threaded steel bar. A ∅14mm circular hole is provided at the end, which serves as a third hinge hole 13 for inserting an M10 fixed screw, which forms part of the first hinge axis 31. The M10 fixed screw and M10 nut form the first hinge axis 31. The adjusting screw is an M14 screw, 14cm long and fully threaded, welded to the first backing plate 1 at a 70° angle in the first direction. Both the first and second fixing nuts 41, 42 are M14 nuts.
