Description

Technical Field

[0001] This utility model relates to the field of building concrete technology, and in particular to an arc-shaped shear wall formwork support device. Background Technology

[0002] The curved shear wall formwork is a customized formwork system designed specifically for casting non-linear concrete shear walls. Its core structure consists of a high-strength curved panel, vertical stiffening ribs, and a back reinforcement frame. The panel is made of thick waterproof plywood or steel formwork, which is cold-pressed into shape by CNC machine tools according to the design curvature and tightly connected to the panel with self-tapping screws.

[0003] Curved shear wall formwork requires a support device because its curved structure is susceptible to deformation, displacement, or even bursting under lateral pressure during concrete pouring. The support device uses a rigid frame and adjustable mechanism to evenly distribute pressure, ensuring the formwork's curvature fits properly and the structure remains stable. This prevents concrete leakage and surface misalignment, ensuring construction safety and the quality of the wall's formation. Existing curved shear wall formwork support devices typically employ a rigid fixing method, where the support angle cannot be dynamically adjusted according to changes in the wall's angle or construction errors, which can easily lead to localized stress concentration or formwork deformation.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example 1:

[0025] Reference Figures 1-4This is the first embodiment of the present utility model. This embodiment provides an arc-shaped shear wall formwork support device, including a wall body 1 and a support member 2. The support member 2 is provided on one side of the wall body 1, the support plate 3 is provided on one side of the support member 2, the guide member 4 is provided on one side of the support plate 3, the guide block 5 is provided inside the guide member 4, the driving mechanism 6 is provided inside the guide block 5, the base plate 7 is provided outside the driving mechanism 6, the fixing plate 8 is fixed on one side of the wall body 1, the splicing mechanism 9 is provided on one side of the fixing plate 8, the mounting plate 10 is fixed on the other side of the fixing plate 8, and the mounting member 11 is provided inside the mounting plate 10.

[0026] In terms of angle adjustment, the guide block 5 is driven to move horizontally by the drive mechanism 6, the guide block 5 drives the guide component 4 to rotate, the guide component 4 drives the support plate 3 to rotate, and the support plate 3 drives the support component 2 to rotate until the support component 2 is tightly attached to the wall 1 template, thus achieving the effect of angle adjustment. In the splicing construction of the wall 1, when two sets of wall 1 need to be connected, the splicing mechanism 9 moves the two fixed plates 8 on both sides to the alignment position simultaneously, ensuring that the two sets of mounting plates 10 are flush, so that the mounting component 11 is inserted into the mounting plate 10 and locked, ultimately achieving rapid and stable splicing of the wall 1, greatly improving construction efficiency and splicing stability.

[0027] It should be noted that: two sets of fixing plates 8 are provided, which are fixed to both sides of the wall 1 respectively. One set of fixing plates 8 is fixed to the splicing frame 91, and the other set is fixed to the splicing plate 92. The splicing of the wall 1 is realized by the interlocking of the splicing frame 91 and the splicing plate 92, so that the splicing surface forms a two-way constraint when subjected to shear force, avoiding the local stress concentration that is easily caused by unilateral fixing. Two sets of mounting plates 10 are provided, and one set of mounting plates 10 is fixed to one set of fixing plates 8, and the other set of mounting plates 10 is fixed to the other set of fixing plates 8. The two sets of mounting plates 10 are connected by bolts 111 through the bolts and tightened with nuts 112. The preload of the bolts 111 is used to press the splicing surfaces of the two sets of wall 1 evenly together, realizing a high-strength shear-resistant connection, avoiding the problems of thermal deformation or misalignment of splicing seams caused by unilateral fixing that are easily caused by traditional welding.

[0028] The drive mechanism 6 includes a threaded rod 61 that is threaded to the inner wall of the guide block 5, and the outer side of the threaded rod 61 is rotatably connected to the top of the base plate 7. One end of the threaded rod 61 is fixed with a turntable 62.

[0029] By rotating the turntable 62, the threaded rod 61 is driven to rotate in place on the top of the base plate 7. The threaded rod 61 and the guide block 5 rotate together, converting the rotational motion into the linear translation of the guide block 5 along the guide rail. This ensures that the support 2 fits the wall 1 with different curvatures, avoiding the accumulation of errors caused by manual adjustment. At the same time, the self-locking characteristic of the thread prevents the concrete side pressure from causing backlash, solving the construction problems of traditional supports that require repeated calibration and are prone to loosening.

[0030] Example 2:

[0031] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] Specifically, the support member 2 includes an arc-shaped plate 21 disposed on one side of the wall 1, and one side of the arc-shaped plate 21 is fixed to one side of the support plate 3, and a reinforcing plate 22 is fixed between the arc-shaped plate 21 and the support plate 3.

[0033] When the support plate 3 rotates, it drives the arc plate 21 and the reinforcing plate 22 to rotate until the arc plate 21 fits tightly against the wall 1 at different angles, forming a surface contact support. This achieves the adaptation of the irregular wall 1 and avoids the problem of local hollowing or stress concentration caused by the mismatch of angles in traditional rigid supports.

[0034] Specifically, the guide member 4 includes a guide rod 41 fixed to one side of the support plate 3, a guide plate 42 rotatably connected to the outer side of the guide rod 41, and the inner wall of the guide plate 42 rotatably connected to the outer side of the guide block 5.

[0035] Regarding the support of wall 1, the threaded rod 61 is driven to rotate by rotating the turntable 62, causing it to rotate along the top of the base plate 7. The threaded rod 61 rotates with the guide block 5, converting the rotation into linear translation of the guide block 5. The guide block 5 drives the guide plate 42 to rotate, and the guide plate 42 rotates along the guide rod 41, which pushes the support plate 3 to rotate. Finally, the support plate 3 drives the arc plate 21 and the reinforcing plate 22 to rotate until the arc plate 21 is tightly attached to the wall 1 at different angles, thus achieving the effect of angle adjustment. This avoids the cumbersome process of customizing arc components for traditional support, effectively prevents support displacement caused by concrete lateral pressure, and ensures construction safety and structural stability.

[0036] Specifically, the splicing mechanism 9 includes a splicing frame 91 fixed to one side of the fixed plate 8, a splicing plate 92 inserted into the inner wall of the splicing frame 91, and one side of the splicing plate 92 fixed to one side of the fixed plate 8.

[0037] A set of fixing plates 8 drives the splicing frame 91 to embed into the splicing plate 92 of another set of fixing plates 8. The splicing is achieved by using a mortise and tenon interlocking structure, so that the splicing surfaces of the two sets of fixing plates 8 are aligned to the same plane, completing the initial positioning of the wall 1 and providing a stable foundation for subsequent locking operations.

[0038] Specifically, the mounting component 11 includes a bolt 111 threaded to the inner wall of the mounting plate 10, and a nut 112 threaded to the outer side of the bolt 111.

[0039] When two sets of wall panels 1 need to be joined, a set of fixing plates 8 drives the splicing frame 91 to be embedded into the splicing plate 92 of the other set of fixing plates 8, so that the splicing surfaces of the two sets of fixing plates 8 are aligned to the same plane. During this process, the two sets of mounting plates 10 are aligned synchronously with the fixing plates 8. Bolts 111 pass through the two sets of mounting plates 10 and are tightened with nuts 112. The preload of the bolts 111 is used to press the splicing surfaces of the two sets of wall panels 1 evenly together, achieving a high-strength shear-resistant connection. This avoids the problems of splicing seam misalignment caused by thermal deformation or unilateral fixing that are easy to produce by traditional welding.

[0040] Example 3:

[0041] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0042] Specifically, a reinforcing plate 12 is fixed to the outer side of the wall 1, and a reinforcing rib 13 is fixed to the inner wall of the reinforcing plate 12.

[0043] The reinforcing plate 12 serves as the main load-bearing surface, bearing lateral loads. The reinforcing ribs 13 are distributed in a grid pattern to disperse and transfer stress. The two are rigidly connected to form an integral whole, significantly improving the bending and shear resistance of the wall 1, while effectively controlling crack propagation.

[0044] Specifically, a connecting plate 14 is fixed to one side of the support plate 3, and a connecting plate 15 is rotatably connected to the inner wall of the connecting plate 14, with the bottom of the connecting plate 15 fixed to the top of the base plate 7.

[0045] When the guide plate 42 pushes the support plate 3 to rotate along the guide rod 41, since the support plate 3 is fixed to the connecting plate 14 and the connecting plate 14 is also rotatably connected to the connecting plate 15, the connecting plate 15 plays a guiding role, restricting the support plate 3 to rotate only along the arc trajectory, so that the support plate 3 rotates smoothly under the drive of the guide rod 41.

[0046] In use, for supporting irregularly shaped walls 1, the rotating turntable 62 drives the threaded rod 61 to rotate, which rotates along the top of the base plate 7. The threaded rod 61 and the guide block 5 rotate threadedly, converting the rotation into linear translation of the guide block 5. The guide block 5 drives the guide plate 42 to rotate, and the guide plate 42 rotates along the guide rod 41, which pushes the support plate 3 to rotate, simultaneously pushing the support plate 3 to swing along an arc trajectory. During this process, the connecting plate 14 rotates along the connecting plate 15, ensuring that the support plate 3 drives the arc plate 21 and the reinforcing plate 22 to fit against the surface of the wall 1 at different angles. When two sets of walls 1 need to be connected, a set of fixing plates 8 drives the splicing frame 91 to embed into the splicing plate 92 of another set of fixing plates 8. This process aligns the splicing surfaces of the two sets of fixing plates 8 to the same plane. During this process, the two sets of mounting plates 10 are aligned synchronously with the fixing plates 8. Bolts 111 pass through the two sets of mounting plates 10 and are tightened with nuts 112. The preload of the bolts 111 is used to uniformly press the splicing surfaces of the two sets of wall 1 together, achieving a high-strength shear-resistant connection. This avoids the problems of thermal deformation or misalignment of splicing seams caused by unilateral fixing that are easily generated by traditional welding. When the wall 1 is under stress, the reinforcing plate 12 serves as the main stress-bearing surface to bear the lateral load, and the reinforcing ribs 13 are distributed in a grid pattern to disperse and transfer stress. The two are rigidly connected to form a whole, which significantly improves the bending and shear resistance of the wall 1 and effectively controls crack propagation.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
