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 cap 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 in the concrete structure.

[0003] During the crown beam construction, first excavate the crown beam foundation trench according to the crown beam trajectory, then tie the steel cage and place it in the crown beam foundation trench; then carry out formwork support, and finally pour cement in the pouring space surrounded by the formwork. After the cement solidifies, remove the formwork to obtain the crown beam.

[0004] When the formwork is supported, a support frame is usually set on the top of the formwork to improve the stability of the formwork. At present, the common support frame is a wooden board structure, with multiple wooden boards evenly spaced along the extension track of the crown beam. However, the formwork and the wooden board are generally fixed with nails, which makes the connection and disassembly process cumbersome and increases the time required for formwork support. 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] The present application provides a crown beam formwork support frame, which adopts the following technical solution: A crown beam formwork support frame, comprising A support column is arranged on the top of the formwork; The support column comprises a first support column and a second support column, wherein the second support column is slidably connected to the first support column; A clamping column, arranged on the supporting column; The clamping column comprises 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; A control component is arranged on the support column, and the control component controls the second support column to slide on the first support column, so that the first clamping column and the second clamping column are moved closer to each other or farther away from each other; A balancing member is arranged on the second supporting column, and the balancing member abuts against the top of the template.

[0007] By adopting the above technical solution, the support column consists of a first support column and a second support column. The second support column can slide in the first support column. In conjunction with the clamping column (including the first clamping column and the second clamping column) and the control assembly, the size of the clamping space can be flexibly adjusted to accommodate crown beam formworks 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. Especially during the fixing and disassembly process, traditional fixing methods such as nails are no longer required, which greatly shortens the working time. In addition, the overall design structure is stable, easy to produce and maintain, and effectively improves the efficiency of formwork support in crown beam construction.

[0008] Optionally, the control assembly includes a control bolt and a control nut; The control bolt is rotatably connected to the first support column, and the control bolt is slidably connected to the second support column; The control nut is fixed in the second support column, and the control bolt is threadedly connected to the control nut.

[0009] By adopting the above technical solution, the control bolt is rotatably connected to the first support column and slidably connected to the second support column, while the control nut is fixed in the second support column and threadedly connected to the control bolt. By rotating the control bolt, the position of the second support column in the first support column can be easily adjusted, thereby controlling the size of the clamping space. This design has a simple structure, convenient operation, high stability and reliability, and ensures that the support frame can accurately adjust the clamping degree of the template during use.

[0010] Optionally, the balancing member is a balancing ring, which is slidably mounted on an outer peripheral side of the second supporting column, and the bottom of the balancing ring is in the same plane as the bottom of the first supporting column.

[0011] 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 to support the second support column and improve the stability of the support frame.

[0012] Optionally, a first abutment column is provided for sliding movement toward or away from the template relative to the clamping column; 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; 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; When the first abutting post slides out of the clamping post, the driving assembly drives the second abutting post to flip relative to the second abutting post and move away from the first abutting post.

[0013] By adopting the above technical solution, when the first abutment column slides into the clamping column, the driving assembly drives the second abutment column to flip close to the first abutment column, thereby enhancing the clamping force of the clamping column on the template; 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 template. This design not only improves the clamping effect of the support frame on the template, but also simplifies the installation and removal process of the support frame, thereby improving construction efficiency.

[0014] Optionally, the driving assembly includes a driving gear, a driving rack, a driving column and a driving block; 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; 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, the driving block is arranged on the outer circumference of the driving column, and the driving block slides in the driving groove; The driving gear is rotatably connected in 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.

[0015] By adopting the above technical solution, the coordinated flipping of the first abutting column and the second abutting column is achieved through the coordinated use of the driving gear, the driving rack, the driving column and the driving block. When the first abutting column slides into the clamping column, the driving rack moves accordingly and meshes with the driving gear. The rotation of the driving gear drives the driving column to slide up and down in the clamping column, and then the sliding of the driving block in the driving groove drives the second abutting column to flip close to the first abutting column. This design has a compact structure, stable transmission and high efficiency, ensuring that the driving component can accurately and reliably complete the flipping control of the second abutting column.

[0016] 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.

[0017] 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.

[0018] Optionally, a curved surface structure located in the driving groove is provided on a side of the driving block away from the driving column.

[0019] 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.

[0020] 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.

[0021] By adopting the above technical solution, a power spring design is added to the clamping column, and the power spring 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 convenient for the second abutment column to be away from the template.

[0022] In summary, the present application includes at least one of the following beneficial effects: 1. The support column consists of a first support column and a second support column. The second support column can slide inside the first support column. Together with the clamping column (including the first clamping column and the second clamping column) and the control assembly, the size of the clamping space can be flexibly adjusted to accommodate crown beam formworks 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. Especially during the fixing and disassembly process, traditional fixing methods such as nails are no longer required, which greatly shortens the working time. In addition, the overall design structure is stable, easy to produce and maintain, and effectively improves the efficiency of formwork support in crown beam construction; 2. When the first abutment column slides into the clamping column, the driving assembly drives the second abutment column to flip close to the first abutment column, thereby enhancing the clamping force of the clamping column on the template; 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 template. This design not only improves the clamping effect of the support frame on the template, but also simplifies the installation and removal process of the template, improving construction efficiency.

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-8 This application is described in further detail.

[0026] The embodiment of the present application discloses a crown beam formwork support frame.

[0027] Embodiment 1 The inventor of the present application has found that when the existing crown beam formwork support frame supports the formwork, since the formwork and the wooden board are fixed by nails, the connection and disassembly process is very troublesome, which increases the time required for the formwork support.

[0028] See also Figure 1 and Figure 2 To this end, the present 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 present application is further described in detail below.

[0029] Among them, the support column 1 is arranged at the top of the template, and there are multiple support columns 1 and they are evenly spaced along the support track of the template. The support column 1 includes a first support column 2 and a second support column 3. The support column 1 is generally made of high-strength steel. The first support column 2 is a cuboid structure, and the length is determined according to the actual use. A support groove is formed in the first support column 2 and penetrates to the outside along the length direction; the second support column 3 is a cuboid structure, and the length is determined according to the actual use. The second support column 3 is slidably connected to the support groove, and the second support column 3 protrudes out of the support groove.

[0030] The clamping column 4 is arranged on the support column 1, and 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, and 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, and the second clamping column 6 is located near the end of the second support column 3 and away from the first support column 2, and 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 the top of the template, and the first clamping column 5 and the second clamping column 6 are against the template. At this time, the template is located between the first clamping column 5 and the second clamping column 6.

[0031] The control component 7 is disposed on the support column 1 , and the control component 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 are moved closer to each other or farther away from each other.

[0032] The control assembly 7 includes a control bolt 71 and a control nut 72. The control bolt 71 adopts a standard thread. The control bolt 71 is rotatably connected to the first support column 2 through a bearing. The central axis of the control bolt 71 is parallel to the length direction of the first support column 2. The second support column 3 is slidably connected to the control bolt 71. The control nut 72 is fixed inside the second support column 3. The control bolt 71 and the control nut 72 are threadedly connected.

[0033] 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 template, and at the same time makes the template 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 template, which is conducive to limiting the relative templates from moving away from each other through the first clamping column 5 and the second clamping column 6, supporting the template, and improving the stability of the template during concrete pouring.

[0034] The balancing part is arranged on the second support column 3, and the balancing part adopts a balancing ring 8. The balancing ring 8 is slidably sleeved on the outer peripheral side of the second support column 3, and the bottom of the balancing ring 8 is in the same plane as the bottom of the first support column 2. When the first support column 2 and the second support column 3 are placed on the top of the template, the balancing ring 8 is slid to the top of the template so that the bottom of the balancing ring 8 can abut against the top of the template. At this time, the template supports the second support column 3 through the balancing ring 8, thereby improving the stability of the support column 1.

[0035] The implementation principle of a crown beam formwork support frame in the first embodiment of the present application is: During construction, the support column 1 is placed on the top of the template, and the balance ring 8 is slid to the top of the template. Then, by controlling the cooperation between the bolt 71 and the nut 72, the first clamping column 5 and the second clamping column 6 can abut against the opposite side walls of the template to achieve efficient support for the template. Especially during the fixing and disassembly process, it is no longer necessary to use traditional fixing methods such as nails, which greatly shortens the working time. In addition, the overall design structure is stable, easy to produce and maintain, and effectively improves the template support efficiency in crown beam construction.

[0036] Embodiment 2 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: an eight-shaped template, an arc-shaped template, etc.

[0037] See also Figure 4 and Figure 5 Specifically, the first abutting columns 41 are symmetrically arranged and slidably connected to the opposite sides of the clamping column 4, respectively, so that the first abutting columns 41 can move closer to or farther from each other. The clamping column 4 is provided with a power spring 44, which is installed in the clamping column 4. One end of the power spring 44 abuts against the first abutting column 41, and the other end abuts against the clamping column 4. When the power spring 44 is elastically released, it pushes the first abutting column 41 to slide out of the clamping column 4.

[0038] There are two groups of second abutment columns 42, each group of second abutment columns 42 is arranged on one clamping column 4, each group of second abutment columns 42 has two and are respectively hinged to the side walls on the opposite sides of the clamping column 4, and at this time, the first abutment column 41 is located between the two second abutment columns 42 in the same group. When flipping, the two second abutment columns 42 in the same group can move closer to or farther away from the first abutment column 41 on a horizontal plane.

[0039] See also Figure 6 and Figure 7 , clamping column 4 (clamping column 4 in Figure 4 The first abutment column 41 is marked with a driving component 9. When the first abutment column 41 slides into the clamping column 4, the driving component 9 drives the second abutment column 42 to flip and approach the first abutment column 41, so that the two second abutment columns 42 in the same group can abut on the template at the same time as the first abutment column 41, thereby improving the stability of the template support; when the first abutment column 41 slides out of the clamping column 4, the driving component 9 drives the two second abutment columns 42 in the same group to flip and move away from the first abutment column 41, so that the second abutment columns 42 are away from the template, which is convenient for removing the crown beam template support frame.

[0040] 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 a 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.

[0041] 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 column 93 is 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 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.

[0042] See also Figure 5 and Figure 6 The driving gear 91 is rotatably connected to the clamping column 4 (the clamping column 4 is 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.

[0043] 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, so that the driving rack 92 slides, driving the driving gear 91 to rotate, and at this time the driving column 93 slides axially, driving the hinge shaft 43 to rotate, so that the second abutting column 42 flips 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, and 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 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 driven by the driving spring 411 until it engages with the driving gear 91, which is conducive to enabling one second abutment column 42 to abut the template when the other second abutment column 42 abuts the template.

[0044] The implementation principle of a crown beam formwork support frame of the second embodiment of the present application is: 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, drives the driving column 93 to move axially, drives the hinge shaft 43 to rotate, and makes the second abutting column 42 drive the connecting column 421 to abut the template, thereby improving the stability and adaptability of the template support.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
