Description

Technical Field

[0001] The present application relates to the technical field of support frames, and in particular to a crown beam formwork support frame. Background Art

[0002] The crown beam is a reinforced concrete continuous beam installed at the top of the supporting structure around the foundation pit. It is usually located above the ground and connects the top of the corbel column or upright column. It is an important component of the concrete structure.

[0003] During the construction of the crown beam, the crown beam base trench is first excavated according to the crown beam trajectory, then the steel cage is tied and placed in the crown beam base trench; then the formwork is supported, and finally cement is poured into the pouring space surrounded by the formwork. After the cement solidifies, the formwork is removed to obtain the crown beam.

[0004] When setting up formwork, a support frame is typically installed on top to enhance its stability. Currently, this support frame is typically constructed of multiple wooden planks evenly spaced along the extension path of the crown beam. However, the formwork and planks are typically secured with nails, making the connection and removal process cumbersome and increasing the time required to support the formwork. Summary of the Invention

[0005] In order to shorten the time required for formwork support, the present application provides a crown beam formwork support frame.

[0006] This application provides a crown beam formwork support frame, which adopts the following technical solutions:

[0007] A crown beam formwork support frame, comprising

[0008] Support columns are set on the top of the formwork;

[0009] The support column includes a first support column and a second support column, and the second support column is slidably connected to the first support column;

[0010] A clamping column, provided on the support column;

[0011] The clamping column includes a first clamping column and a second clamping column, the first clamping column is arranged at the bottom of the first support column, the second clamping column is arranged at the bottom of the second support column, and a clamping space is formed between the first clamping column and the second clamping column;

[0012] a control assembly, disposed on the support column, for controlling the second support column to slide relative to the first support column, such that the first clamping column and the second clamping column move closer to or farther from each other;

[0013] A balancing member is provided on the second supporting column, and the balancing member abuts against the top of the template.

[0014] By adopting this technical solution, the support column consists of a first support column and a second support column. The second support column can slide within the first support column. In conjunction with the clamping columns (including the first and second clamping columns) and the control assembly, the size of the clamping space can be flexibly adjusted to accommodate crown beam formwork of varying sizes and shapes. This design not only improves the adaptability and flexibility of the support frame but also ensures the stability and safety of the formwork during the pouring process. In particular, during the fixing and removal processes, traditional fixing methods such as nails are no longer required, significantly reducing work time. Furthermore, the overall design provides a stable structure, facilitating production and maintenance, and effectively improving the efficiency of formwork support during crown beam construction.

[0015] Optionally, the control assembly includes a control bolt and a control nut;

[0016] The control bolt is rotatably connected to the first support column, and the control bolt is slidably connected to the second support column;

[0017] The control nut is fixed in the second support column, and the control bolt is threadedly connected to the control nut.

[0018] By adopting this technical solution, the control bolt is rotationally connected to the first support column and slidably connected to the second support column, while the control nut is fixed within the second support column and threadedly connected to the control bolt. By rotating the control bolt, the position of the second support column within the first support column can be easily adjusted, thereby controlling the size of the clamping space. This design is simple in structure, easy to operate, and has high stability and reliability, ensuring that the support frame can accurately adjust the clamping degree of the template during use.

[0019] Optionally, the balancing member is a balancing ring, which is slidably sleeved on the outer peripheral side of the second support column, and the bottom of the balancing ring and the bottom of the first support column are in the same plane.

[0020] By adopting the above technical solution, the bottom of the balance ring and the bottom of the first support column are in the same plane, so that the balance ring can abut the top of the template, support the second support column, and improve the stability of the support frame.

[0021] Optionally, a first abutment column is provided for sliding toward or away from the template relative to the clamping column;

[0022] The side walls opposite to the clamping column are respectively hinged with second abutment columns, and the first abutment columns are arranged between the second abutment columns;

[0023] The clamping column is provided with a driving assembly, and when the first abutting column slides into the clamping column, the driving assembly drives the second abutting column to flip relative to the second abutting column and approach the first abutting column;

[0024] When the first abutting post slides out of the clamping post, the driving assembly drives the second abutting post to flip relative to and away from the first abutting post.

[0025] By adopting this technical solution, when the first abutment column slides into the clamping column, the drive assembly drives the second abutment column to flip closer to the first abutment column, thereby strengthening the clamping force of the clamping column on the formwork. Conversely, when the first abutment column slides out of the clamping column, the second abutment column flips away from the first abutment column, facilitating the removal and replacement of the formwork. This design not only improves the support frame's clamping effect on the formwork, but also simplifies the support frame installation and removal process, improving construction efficiency.

[0026] Optionally, the driving assembly includes a driving gear, a driving rack, a driving column and a driving block;

[0027] The clamping column is rotatably connected to a hinge shaft, and the second clamping column is arranged on the outer peripheral side of the hinge shaft;

[0028] The driving column slides up and down in the clamping column, the driving column is parallel to the hinge shaft, a driving groove extending along a spiral track is formed on the outer circumference of the hinge shaft, and the driving block is provided on the outer circumference of the driving column, and the driving block slides in the driving groove;

[0029] The driving gear is rotatably connected to the clamping column, the driving gear is arranged on the side wall of the first abutting column, and the driving gear is meshed with the driving rack.

[0030] By adopting the above technical solution, the coordinated flipping of the first and second abutting posts is achieved through the coordinated use of the drive gear, drive rack, drive post, and drive block. When the first abutting post slides into the clamping post, the drive rack moves accordingly and engages with the drive gear. The rotation of the drive gear drives the drive post to slide up and down within the clamping post. The sliding of the drive block within the drive slot then drives the second abutting post to flip closer to the first abutting post. This design offers a compact structure, smooth transmission, and high efficiency, ensuring that the drive assembly can accurately and reliably control the flipping of the second abutting post.

[0031] Optionally, the driving rack slides on the first abutting column, and the first abutting column is provided with a driving spring, and the driving spring drives the driving rack to protrude from the first abutting column.

[0032] By adopting the above technical solution, when the first abutment column and a second abutment column are started to abut the template, the driving clamping column continues to approach the abutment template, and the second abutment column of the abutment template is in a stationary state. At this time, the driving gear slides on the driving rack, so that the driving rack slides into the connecting groove and slides out of the connecting groove under the drive of the driving spring to engage with the driving gear, which is conducive to enabling one second abutment column to abut the template when the other second abutment column abuts the template.

[0033] Optionally, a curved surface structure located in the driving groove is provided on a side of the driving block away from the driving column.

[0034] By adopting the above technical solution, a curved surface structure is provided on the side of the driving block away from the driving column. This design enables the driving block to slide more smoothly and evenly in the driving groove, thereby reducing friction and wear during the sliding process.

[0035] Optionally, the clamping column is provided with a power spring, and the power spring drives the first abutting column to slide out of the clamping column.

[0036] By adopting the above technical solution, a power spring design is added to the clamping column, which always drives the first abutment column to slide out of the clamping column, so that when the clamping column is away from the template, the first abutment column can slide out of the clamping column, making it easier for the second abutment column to move away from the template.

[0037] In summary, this application has at least one of the following beneficial effects:

[0038] 1. The support column consists of a first support column and a second support column. The second support column can slide within the first support column. In conjunction with the clamping columns (including the first and second clamping columns) and the control assembly, the size of the clamping space can be flexibly adjusted to accommodate crown beam formwork of different sizes and shapes. This design not only improves the adaptability and flexibility of the support frame, but also ensures the stability and safety of the formwork during the pouring process. In particular, during the fixing and disassembly processes, traditional fixing methods such as nails are no longer required, significantly reducing working time. In addition, the overall design structure is stable, easy to produce and maintain, and effectively improves the efficiency of formwork support during crown beam construction.

[0039] 2. When the first abutment column slides into the clamping column, the drive assembly drives the second abutment column to flip closer to the first abutment column, thereby strengthening the clamping column's clamping force on the formwork. Conversely, when the first abutment column slides out of the clamping column, the second abutment column flips away from the first abutment column, facilitating the removal and replacement of the formwork. This design not only improves the support frame's clamping effect on the formwork, but also simplifies the formwork installation and removal process, improving construction efficiency.

[0049] The following is combined with Figure 1-8 This application is described in further detail.

[0050] The embodiment of the present application discloses a crown beam formwork support frame.

[0051] Example 1

[0052] The inventors of the present application have discovered that, when supporting the formwork, the existing crown beam formwork support frame fixes the formwork and the wooden board with nails, which makes the connection and disassembly process very troublesome and increases the time required for formwork support.

[0053] See also Figure 1 and Figure 2To this end, this application mainly adopts a technical solution: a crown beam formwork support frame, including a support column 1, a clamping column 4, a control component 7 and a balancing member, which significantly shortens the time required for formwork support. The application is further described in detail below.

[0054] The support columns 1 are arranged at the top of the formwork. There are multiple support columns 1, evenly spaced along the formwork's support trajectory. The support columns 1 include a first support column 2 and a second support column 3, typically made of high-strength steel. The first support column 2 is a rectangular parallelepiped structure, with a length determined based on actual use. A support groove is formed within the first support column 2, extending longitudinally to the outside. The second support column 3 is a rectangular parallelepiped structure, with a length determined based on actual use. It is slidably connected to the support groove and protrudes beyond the groove.

[0055] The clamping column 4 is provided on the support column 1. The clamping column 4 includes a first clamping column 5 and a second clamping column 6. The first clamping column 5 and the second clamping column 6 have the same structure, and are both rectangular structures. The first clamping column 5 is fixedly connected to the bottom of the first support column 2. The first clamping column 5 is located near the end of the first support column 2 and away from the second support column 3. The second clamping column 6 is fixedly connected to the bottom of the second support column 3. The second clamping column 6 is located near the end of the second support column 3 and away from the first support column 2. A clamping space is formed between the first clamping column 5 and the second clamping column 6. During installation, the first support column 2 and the second support column 3 are placed on top of the template, and the first clamping column 5 and the second clamping column 6 are facing the template. At this time, the template is located between the first clamping column 5 and the second clamping column 6.

[0056] The control assembly 7 is disposed on the support column 1 , and the control assembly 7 controls the second support column 3 to slide on the first support column 2 , so that the first clamping column 5 and the second clamping column 6 move closer to or farther away from each other.

[0057] The control assembly 7 includes a control bolt 71 and a control nut 72. The control bolt 71 uses a standard thread and is rotatably connected to the first support column 2 via a bearing. The central axis of the control bolt 71 is parallel to the length of the first support column 2. The second support column 3 is slidably connected to the control bolt 71, and the control nut 72 is fixed inside the second support column 3. The control bolt 71 and the control nut 72 are threadedly connected.

[0058] When the control bolt 71 rotates forward, the control nut 72 is used to make the second support column 3 slide out of the support groove. At this time, the clamping space is increased, which makes it convenient to place the support column 1 on the top of the formwork, and at the same time makes the formwork between the first clamping column 5 and the second clamping column 6; when the control bolt 71 is reversed, the control nut 72 is used to cooperate to make the second support column 3 slide into the support groove. At this time, the clamping space is reduced, so that the first clamping column 5 and the second clamping column 6 can respectively abut against the opposite side walls of the relative formwork, which is conducive to limiting the relative formwork from moving away from each other through the first clamping column 5 and the second clamping column 6, supporting the formwork, and improving the stability of the formwork during concrete pouring.

[0059] A balancing element, in the form of a balancing ring 8, is mounted on the second support column 3. The balancing ring 8 slides over the outer periphery of the second support column 3, with the bottom of the balancing ring 8 flush with the bottom of the first support column 2. When the first and second support columns 2 and 3 are placed on top of the formwork, the balancing ring 8 is slid to the top of the formwork, so that the bottom of the balancing ring 8 abuts the top of the formwork. The formwork now supports the second support column 3 through the balancing ring 8, improving the stability of the support column 1.

[0060] The implementation principle of a crown beam formwork support frame in the first embodiment of the present application is as follows:

[0061] During construction, the support column 1 is placed on top of the formwork, and the balancing ring 8 is slid to the top of the formwork. Then, by engaging the control bolts 71 and control nuts 72, the first clamping column 5 and the second clamping column 6 abut the opposing sidewalls of the formwork, effectively supporting the formwork. This eliminates the need for traditional fixing methods such as nails during the fastening and removal process, significantly reducing work time. Furthermore, the overall design is structurally stable, facilitating production and maintenance, effectively improving formwork support efficiency during crown beam construction.

[0062] Example 2

[0063] The difference between the second embodiment of the present application and the first embodiment is that: Figure 3 and Figure 4 The clamping column 4 is provided with a first abutting column 41 and a second abutting column 42, so that the support frame can support templates along different trajectories, such as: figure eight templates, arc templates, etc.

[0064] See also Figure 4 and Figure 5Specifically, the first abutting posts 41 are symmetrically arranged and slidably connected to the opposite sides of the clamping posts 4, allowing the first abutting posts 41 to move closer to or farther from each other. The clamping posts 4 are provided with a power spring 44, which is installed inside the clamping posts 4. One end of the power spring 44 abuts the first abutting post 41, and the other end abuts the clamping post 4. When the power spring 44 is released, it pushes the first abutting post 41 to slide out of the clamping post 4.

[0065] There are two groups of second abutment posts 42, each group of which is located on one clamping post 4. Each group of second abutment posts 42 has two second abutment posts 42, each hinged to opposite side walls of the clamping post 4. In this case, the first abutment post 41 is located between the two second abutment posts 42 in the same group. When flipped, the two second abutment posts 42 in the same group can move toward or away from the first abutment post 41 on a horizontal plane.

[0066] See also Figure 6 and Figure 7 , clamping column 4 (clamping column 4 in Figure 4 (marked in the middle) is provided with a driving component 9. When the first abutting column 41 slides into the clamping column 4, the driving component 9 drives the second abutting column 42 to flip close to the first abutting column 41, so that the two second abutting columns 42 in the same group can abut on the formwork at the same time as the first abutting column 41, thereby improving the stability of the formwork support; when the first abutting column 41 slides out of the clamping column 4, the driving component 9 drives the two second abutting columns 42 in the same group to flip away from the first abutting column 41, so that the second abutting columns 42 are away from the formwork, thereby facilitating the removal of the crown beam formwork support frame.

[0067] The driving assembly 9 includes a driving gear 91, a driving rack 92, a driving column 93 and a driving block 94. The clamping column 4 is rotatably connected to the hinge shaft 43. The second abutment column 42 is fixed on the outer peripheral side of the hinge shaft 43 and corresponds one to one. The second abutment column 42 is slidably connected to the clamping column 4.

[0068] See also Figure 7 and Figure 8 The driving column 93 slides up and down on the clamping column 4 (the clamping column 4 is Figure 4(marked in the middle), there are two drive columns 93 and they correspond one to one with the hinge shaft 43, and the drive columns 93 are parallel to the hinge shaft 43. A drive block 94 is fixedly connected to the outer peripheral side of the drive column 93, and a drive groove 431 is formed on the outer peripheral side of the hinge shaft 43, and the drive groove 431 extends along a spiral trajectory. An arc surface structure is formed on the side of the drive block 94 away from the drive column 93, and the drive block 94 protrudes into the drive groove 431, and the arc surface structure is located in the drive groove 431. The design of the arc surface structure enables the drive block 94 to slide more smoothly in the drive groove 431 during the sliding process, reducing the wear caused by friction. The arc surface structure can be processed and manufactured by high-precision turning or molding technology to ensure its surface smoothness and dimensional accuracy. When the drive column 93 moves up and down, the drive block 94 slides in the drive groove 431, driving the hinge shaft 43 to rotate, so that the second abutment column 42 flips on the horizontal plane.

[0069] See also Figure 5 and Figure 6 The driving gear 91 is connected to the clamping column 4 (the clamping column 4 is in the Figure 4 (marked in the middle), the driving gear 91 corresponds to the driving column 93 one by one, and a threaded hole is formed in the middle of the driving gear 91, and the driving column 93 is threadedly connected to the threaded hole. A connecting groove is formed on the side wall of the first abutting column 41 close to the driving gear 91, and the driving rack 92 corresponds to the connecting groove one by one, and the driving rack 92 slides in the connecting groove. And when the first abutting column 41 slides on the clamping column 4, the driving rack 92 slides on the clamping column 4. The first abutting column 41 is provided with a driving spring 411, and there are multiple driving springs 411 and they are respectively installed in the connecting grooves. One end of the driving spring 411 is fixed to the driving rack 92, and the other end is fixed to the groove wall on the side of the connecting groove away from the groove. When the driving spring 411 is elastically released, it pushes the driving rack 92 close to the driving gear 91, and the driving gear 91 is meshed with the driving rack 92.

[0070] When the two clamping columns 4 approach each other, the first abutting column 41 and the second abutting column 42 abut against the opposite sides of the template; then the two first abutting columns 41 slide into the two clamping columns 4 respectively, causing the driving rack 92 to slide, driving the driving gear 91 to rotate, at this time the driving column 93 slides axially, driving the hinge shaft 43 to rotate, causing the second abutting column 42 to flip toward the direction of approaching the first abutting column 41, and the second abutting column 42 can abut against the template; the second abutting column 42 is fixedly connected to the end away from the clamping column 4 with a connecting column 421, and the connecting column 421 is perpendicular to the second abutting column 42. The second abutting column 42 drives the connecting column 421 to abut against the template, thereby increasing the contact area between the second abutting column 42 and the template, thereby improving the support stability of the template. When the first abutment column 41 and one of the second abutment columns 42 abut against the template, the driving clamping column 4 continues to approach the abutment template, and the second abutment column 42 abutting the template is in a stationary state. At this time, the driving gear 91 slides on the driving rack 92, so that the driving rack 92 slides into the connecting groove and slides out of the connecting groove under the drive of the driving spring 411 until it engages with the driving gear 91, which is conducive to enabling one second abutment column 42 to abut against the template when the other second abutment column 42 abuts against the template.

[0071] The implementation principle of a crown beam formwork support frame in the second embodiment of the present application is as follows:

[0072] When the two clamping columns 4 approach and abut the template, the first abutting column 41 slides into the clamping column 4, so that the driving rack 92 cooperates with the driving gear 91, driving the driving column 93 to move axially, driving the hinge shaft 43 to rotate, so that the second abutting column 42 drives the connecting column 421 to abut the template, thereby improving the stability and adaptability of the template support.

[0073] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
