Description

Technical Field

[0001] This utility model relates to the field of quick-release formwork technology for precast beams and slabs, specifically a quick-release formwork support device for precast beams and slabs. Background Technology

[0002] Precast beam and slab quick-release formwork is a highly efficient construction equipment designed specifically for the rapid demolding of precast concrete beam and slab components. Its core advantages lie in its unique early-strength support and modular connection system. After the concrete reaches its initial setting strength, the side formwork can be quickly removed through simple mechanical operations (such as loosening key components), while retaining the bottom support. This significantly shortens the formwork turnaround time, improves component production efficiency, and effectively reduces labor intensity and formwork wear. This technology is a key link in realizing building industrialization, shortening the construction period, and reducing costs.

[0003] Most of the precast beam and slab quick-release formwork support devices commonly found on the market use independent steel column support systems. This support method is quite cumbersome during the preparation period, and when supporting different precast beams, it is necessary to re-plan the plan layout of the columns. The repetitive handling, positioning and adjustment work not only greatly increases the preparation time before construction, but also reduces construction efficiency. Utility Model Content

[0026] Example 1

[0027] Reference Figure 1-4 This is the first embodiment of the present utility model, which provides a quick-release formwork support device for precast beams and slabs, including a support base 1 and a support column 2. The lower surface of the support column 2 is fixedly connected to the upper surface of the support base 1, and a stabilizing mechanism 3 is provided on the outer surface of the support base 1.

[0028] There are two stabilizing mechanisms 3. The two stabilizing mechanisms 3 include a stabilizing plate 31, a pushing plate 32, a through groove 33 and a sliding component 34. The through groove 33 is opened on the left and right sides of the support base 1. The outer surface of the pushing plate 32 is slidably connected to the inner wall of the through groove 33. The opposite side of the stabilizing plate 31 is fixedly connected to the opposite end of the pushing plate 32. The sliding component 34 is set at the opposite end of the pushing plate 32.

[0029] The sliding assembly 34 includes a slider 341 and a sliding rod 342. The outer surface of the slider 341 is fixedly connected to one end of the push plate 32. The outer surface of the sliding rod 342 is slidably connected to the inner wall of the slider 341. Both the left and right ends of the sliding rod 342 are fixedly connected to the inner wall of the support base 1.

[0030] Specifically, this design increases the contact area between the bottom surface of the support device and the ground, thus improving the stability of the device.

[0031] Furthermore, by moving the slider 341 outward along the outer surface of the sliding rod 342, the slider 341 pushes the push plate 32, causing the push plate 32 to pass through the inner wall of the through groove 33. At the same time, the push plate 32 can push the stabilizing plate 31, causing the stabilizing plate 31 to move outward, thereby increasing the contact area between the support base 1 and the ground and improving the stability of the precast beam formwork support.

[0032] Example 2

[0033] In the second embodiment of this utility model, a transmission component 4 is provided at one end of the slider 341. The transmission component 4 includes a toothed plate 41, a gear 42, and a connecting column 43. Two toothed plates 41 are provided, and the opposite sides of the two toothed plates 41 are fixedly connected to one end of the slider 341. The outer surface of the gear 42 is meshed with the opposite side of the toothed plate 41. The outer surface of the connecting column 43 is fixedly connected to the inner wall of the gear 42. Both the upper and lower ends of the connecting column 43 are rotatably connected to the inner wall of the support base 1 through bearings.

[0034] A drive assembly 5 is provided on the upper end face of the connecting column 43. The drive assembly 5 includes a first threaded rod 51, a first transmission block 52, and a first motor 53. The lower end face of the first threaded rod 51 is fixedly connected to the upper end face of the connecting column 43. The outer surface of the first threaded rod 51 is rotatably connected to the inner wall of the support column 2 through a bearing. The inner wall of the first transmission block 52 is rotatably connected to the outer surface of the first threaded rod 51 through a thread. The output end of the first motor 53 is fixedly connected to the upper end face of the first threaded rod 51, and the lower surface of the first motor 53 is fixedly connected to the upper surface of the support column 2.

[0035] The outer surface of the support column 2 is provided with a first sliding groove 6, which is opened on the inner wall of the support column 2. The inner wall of the first sliding groove 6 is slidably connected to the outer surface of the first transmission block 52.

[0036] A support assembly 7 is provided on the outer surface of the first transmission block 52. The support assembly 7 includes a support rod 71, a support plate 72, and a limiting plate 73. The end of the support rod 71 near the first transmission block 52 is fixedly connected to the outer surface of the first transmission block 52. The lower surface of the support plate 72 is fixedly connected to the upper end face of the support rod 71. Two limiting plates 73 are provided, and both limiting plates 73 are provided on the upper surface of the support plate 72.

[0037] Specifically, when the first motor 53 is started, the support plate 72 can automatically rise until it is tightly attached to the bottom of the precast beam, thus longitudinally limiting the precast beam. The threaded connection between the first threaded rod 51 and the first transmission block 52 has self-locking properties, which improves the stability after support.

[0038] Furthermore, the first motor 53 drives the first threaded rod 51 to rotate. The first threaded rod 51 drives the first transmission block 52 to move upward along the inner wall of the first slide groove 6 through the thread. The first transmission block 52 then pushes the support plate 72 upward through the support rod 71 until the upper surface of the support plate 72 is tightly attached to the lower surface of the precast beam. Then, the limiting plate 73 moves to one side of the precast beam until the opposite side of the limiting plate 73 is tightly attached to the left and right sides of the precast beam. At the same time, the rotation of the first threaded rod 51 can drive the lower surface connecting column 43 to rotate. The connecting column 43 drives the gear 42 to rotate, so that the gear 42 meshes with the toothed plate 41, causing the toothed plate 41 to drive the slider 341 to move outward along the outer surface of the sliding rod 342.

[0039] Example 3

[0040] In the third embodiment of this utility model, an adjustment component 8 is provided on the surface of the support plate 72. The adjustment component 8 includes a positive and negative threaded rod 81, a second transmission block 82, a second motor 83, and a second slide groove 84. There are two second slide grooves 84, which are opened on the upper surface of the support plate 72. The outer surface of the positive and negative threaded rod 81 is rotatably connected to the inner wall of the support plate 72 through a bearing. There are two second transmission blocks 82, and the inner walls of the two second transmission blocks 82 are rotatably connected to the outer surface of the positive and negative threaded rod 81 through a thread. The outer surface of the second transmission block 82 is slidably connected to the inner wall of the second slide groove 84. The upper surface of the second transmission block 82 is fixedly connected to the lower surface of the limiting plate 73. The output end of the second motor 83 is fixedly connected to the right end face of the positive and negative threaded rod 81, and the left surface of the second motor 83 is fixedly connected to the right surface of the support plate 72.

[0041] Specifically, the stroke and force of the limiting plate 73 can be precisely controlled by the second motor 83, so that the limiting plate 73 can be tightly and firmly attached to the side of the precast beam, which greatly enhances the stability of the support.

[0042] Furthermore, the second motor 83 drives the positive and negative threaded rod 81 to rotate. The positive and negative threaded rod 81 drives the second transmission block 82 to move along the inner wall of the second slide groove 84 towards one side of the precast beam through the thread. The second transmission block 82 can drive the limiting plate 73 on the upper surface to move together until the opposite side of the limiting plate 73 is tightly attached to the left and right sides of the precast beam.

[0043] Working principle:

[0044] The first motor 53 drives the first threaded rod 51 to rotate. The first threaded rod 51 drives the first transmission block 52 to move upward along the inner wall of the first slide groove 6 via its thread. The first transmission block 52 then pushes the support plate 72 upward via the support rod 71 until the upper surface of the support plate 72 is tightly attached to the lower surface of the precast beam. At the same time, the rotation of the first threaded rod 51 drives the lower surface connecting column 43 to rotate. The connecting column 43 then drives the gear 42 to rotate, so that the gear 42 meshes with the toothed plate 41. This causes the toothed plate 41 to drive the slider 341 to move outward along the outer surface of the sliding rod 342. The slider 341 then... Pushing the push plate 32 allows it to pass through the inner wall of the through groove 33. Simultaneously, the push plate 32 pushes the stabilizing plate 31, causing it to move outward. This increases the contact area between the support base 1 and the ground, improving the stability of the precast beam template support. Then, the second motor 83 drives the positive and negative threaded rod 81 to rotate. The positive and negative threaded rod 81 drives the second transmission block 82 to move along the inner wall of the second slide groove 84 towards one side of the precast beam through the thread. The second transmission block 82 can also drive the upper surface limiting plate 73 to move together until the opposite side of the limiting plate 73 is tightly fitted with the left and right sides of the precast beam, thus completing the support of the precast beam.

[0045] In summary, the coordination of the stabilizing mechanism 3, transmission component 4, drive component 5, first slide 6, support component 7, and adjustment component 8 solves the problem of having to replan the planar layout of the supports when supporting different precast beams, and the repetitive handling, positioning, and adjustment work, which not only greatly increases the preparation time before construction but also reduces construction efficiency.
