Description

Technical Field

[0001] This utility model relates to the field of bridge construction, and in particular to a square double-clamp single-column pier cap beam construction support. Background Technology

[0002] In modern bridge construction projects, the construction of single-column pier cap beams is a crucial step, directly affecting the stability and load-bearing capacity of the bridge structure. The square double-hoop single-column pier cap beam construction scaffold, as an important support system for erecting the cap beam, bears the heavy responsibility of bearing construction loads, ensuring construction safety, and ensuring the quality of cap beam formation.

[0003] As the scale of bridge construction continues to expand, higher requirements are placed on the construction efficiency, quality control, and safety assurance of single-column pier cap beams.

[0004] Currently, existing square double-clamp single-column pier cap beam construction supports have shortcomings: some supports have fixed structural designs, making it difficult to quickly and accurately adapt to single-column piers of different sizes and geological conditions. They often require a lot of time for modification and debugging before construction, delaying the construction period. At the same time, some supports are prone to problems such as clamp slippage and structural deformation under complex loads. For example, the friction between the clamp and the pier column is insufficient, which cannot effectively resist construction loads, causing the clamp to shift, threatening construction safety, increasing maintenance costs, and failing to meet the needs of rapid construction. Therefore, a square double-clamp single-column pier cap beam construction support is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a square double-clamp single-column pier cap beam construction support, which aims to improve the problem in the existing technology that it is difficult to quickly and accurately adapt to single-column piers of different sizes and geological conditions, and that a lot of time is often required for modification and debugging before construction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a square double-clamp single-column pier cap beam construction support, comprising a rectangular pier column, wherein the surface of the rectangular pier column is provided with two sets of upper and lower square clamp components;

[0007] The upper and lower square clamp assemblies include three back frames. Each of the three back frames consists of two L-shaped back frame beams connected by back frame flanges and high-strength bolts. Adjacent back frames are connected by vertical steel pipe uprights. Back frame stiffening plates are fixedly connected to the corners of the L-shaped back frame beams of the three back frames. Vertical back ribs are fixedly connected to the rear ends of the three back frames. Back frame ear plates are fixedly connected to the rear ends of the three back frames. Pins are fixedly connected inside the ear plates. Anti-slip friction panels are provided at the bottom of the vertical back ribs. Support components are also provided on the upper surface of the rectangular pier.

[0008] As a further description of the above technical solution:

[0009] The support assembly also includes a support diagonal member, the top of which is fixedly connected to an upper chord. The end of the support diagonal member away from the upper chord is fixedly connected to a diagonal member lug. A support stiffening plate is fixedly connected at the connection between the support diagonal member and the upper chord. Four sets of support stiffening plates are provided. The left and right sets of support stiffening plates are fixedly connected by an upper chord flange and high-strength bolts. A transverse connecting rod is fixedly connected between the front and rear sets of support stiffening plates. Multiple sets of support diagonal members are provided, with the front and rear sets fixedly connected by a connecting system. A relief block is provided on the surface of the upper chord. A distribution beam is fixedly connected to the top of the relief block. A template and support assembly are provided at the top of the distribution beam.

[0010] As a further description of the above technical solution:

[0011] The template and support assembly includes a template support, on the surface of which a cast-in-place steel template is provided, and a cap beam is fixedly connected to the surface of the cast-in-place steel template.

[0012] As a further description of the above technical solution:

[0013] The upper chord flange and high-strength bolts include a flange plate, the outer arc surface of which is fixedly connected with high-strength bolts, and the surface of the flange plate is provided with a flange stiffening plate.

[0014] As a further description of the above technical solution:

[0015] The end of the anti-slip friction panel away from the vertical back rib is in contact with the outer wall of the rectangular pier.

[0016] As a further description of the above technical solution:

[0017] The end of the diagonal brace ear plate away from the supporting diagonal brace is hinged to the pin.

[0018] As a further description of the above technical solution:

[0019] The top end of the distribution beam is fixedly connected to the bottom end of the outer wall of the template support.

[0020] This utility model has the following beneficial effects:

[0021] (1) In this utility model, the square clamp assembly composed of three back frames is flexibly connected by back frame flanges and high-strength bolts, and can be assembled and adjusted according to the specific dimensions of the single-column pier to adapt to different pier cross-sectional shapes and sizes. The vertical steel pipe uprights firmly connect the three back frames into a whole, enhancing the stability of the support under different geological conditions. At the same time, the anti-slip friction panel is in close contact with the outer wall of the pier, effectively resisting the slippage of the clamp by using friction, ensuring that the support can be stably supported on various single-column piers, meeting diverse construction needs, and greatly improving the adaptability of the construction support to complex working conditions.

[0022] (2) In this utility model, in the support assembly, the supporting diagonal bar and the upper chord are welded to form a stable structural system. The supporting stiffening plate disperses the stress at the weld, preventing damage to this part due to stress concentration and ensuring structural strength. The upper chord flange and high-strength bolts not only facilitate installation and disassembly but also ensure the reliability of the connection. The transverse connecting rod and connection system increase the transverse stiffness and overall stability of the support assembly, enabling the bracket to better withstand complex construction loads such as concrete pouring.

[0023] (3) In this utility model, the design of the upper chord flange and high-strength bolts makes the installation and disassembly of the support components simple and efficient, reducing the manpower and time costs in the construction process. The setting of the unloading block enables the template and support components to be safely and smoothly unloaded by controlling its working state after the cap beam construction is completed, avoiding damage to the support by the traditional disassembly method and improving the reuse rate of the support.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 - Figure 3 One embodiment of this utility model is a square double-clamp single-column pier cap beam construction support, which includes a rectangular pier 2, and the surface of the rectangular pier 2 is provided with two sets of upper and lower square clamp components 4.

[0035] Reference Figure 1 and Figure 4 and Figure 7The upper and lower square clamp assembly 4 includes a three-layer back frame 41, consisting of an upper, middle, and lower back frame. Specifically, each back frame plays a crucial role in load-bearing and connection within the actual structure. Each back frame is fixedly connected by two L-shaped back frame beams via back frame flanges and high-strength bolts 46. This connection method ensures the strength and stability of the back frame structure. Adjacent back frames of the three layers 41 are fixedly connected by vertical steel pipe supports 43. The vertical steel pipe supports 43 effectively connect the three layers 41 from independent parts into a whole, enhancing the overall rigidity and stability of the clamp assembly, allowing it to better withstand various loads during construction. Back frame stiffening plates 48 are fixedly connected to the corners of the L-shaped back frame beams of the three layers 41. Since the corners are areas of high stress concentration, welding back frame stiffening plates 48 at the corners effectively prevents stress concentration and structural damage, improving structural integrity. To ensure the reliability of the clamp assembly, a vertical back rib 42 is fixedly connected to the rear end of the three-layer back frame 41. The vertical back rib 42 further strengthens the structural strength of the back frame and also provides an installation base for the anti-slip friction panel 45. A back frame ear plate 44 is fixedly connected to the rear end of the three-layer back frame 41. A pin 47 is fixedly connected inside the back frame ear plate 44. The back frame ear plate 44 and the pin 47 are designed to achieve a hinged connection with the support assembly 5, so that the entire structure can better transmit loads and adapt to stress deformation. The bottom end of the vertical back rib 42 has an anti-slip friction panel 45. The end of the anti-slip friction panel 45 away from the vertical back rib 42 contacts the outer wall of the rectangular pier 2. By setting the anti-slip friction panel 45, anti-slip friction resistance can be provided between the back rib and the rectangular pier 2, preventing the clamp assembly from sliding on the pier and ensuring safety and stability during construction. The upper surface of the rectangular pier 2 is also provided with the support assembly 5.

[0036] Reference Figure 1 and Figure 4The support assembly 5 also includes a support diagonal rod 51, with an upper chord rod 52 fixedly connected to its top. The support diagonal rod 51 and the upper chord rod 52 are welded together, ensuring the connection strength and forming a stable structural system for the support assembly 5. A diagonal rod lug 53 is fixedly connected to the end of the support diagonal rod 51 away from the upper chord rod 52. The end of the diagonal rod lug 53 away from the support diagonal rod 51 is hinged to a pin 47. This hinged connection connects the square clamp assembly and the support assembly 5, allowing for some rotational deformation under stress to adapt to the structural stress state. A support stiffening plate 55 is fixedly connected at the connection between the support diagonal rod 51 and the upper chord rod 52. Since the weld is also a stress concentration area, four sets of support stiffening plates 55 are provided to effectively disperse stress and prevent damage to this area. The left and right sets of support stiffening plates 55 are fixedly connected by an upper chord flange and high-strength bolts 54. This connection method facilitates the installation and disassembly of the support assembly 5 while ensuring... To ensure reliable connection, a transverse connecting rod 57 is fixedly connected between the front and rear sets of support stiffening plates 55. The transverse connecting rod 57 increases the transverse stiffness of the support assembly 5, enabling it to maintain stability better when bearing loads. Multiple sets of support diagonal rods 51 are provided, and the front and rear sets of support diagonal rods 51 are fixedly connected by a connecting system 56. The connecting system 56 further enhances the overall stability of the support assembly 5, enabling it to jointly bear the load. The surface of the upper chord 52 is provided with a relief block 58. The function of the relief block 58 is to facilitate the removal of the formwork and support assembly 3 after the cap beam 1 is constructed. By controlling the working state of the relief block 58, the formwork and support assembly 3 can be safely and smoothly removed. The top of the relief block 58 is fixedly connected with a distribution beam 59. The function of the distribution beam 59 is to evenly distribute the load transmitted from the formwork and support assembly 3 to the upper chord 52, avoiding excessive local stress. The top of the distribution beam 59 is fixedly connected to the bottom of the outer wall of the formwork support 32, and the top of the distribution beam 59 is provided with the formwork and support assembly 3.

[0037] Reference Figure 5 The upper chord flange and high-strength bolts 54 include a flange plate 541, with high-strength bolts 542 fixedly connected to the outer arc surface of the flange plate 541. A flange stiffening plate 543 is provided on the surface of the flange plate 541. The flange stiffening plate 543 further enhances the strength and stability of the flange connection, ensuring that the connection between the upper chords 52 is firm and reliable.

[0038] Reference Figure 1 and Figure 6The template and support assembly 3 includes a template support 32, on the surface of which a cast-in-place steel template 31 is provided. The cast-in-place steel template 31 has advantages such as high strength, high rigidity and flat surface, which can ensure the forming quality of the cap beam 1. The cap beam 1 is fixedly connected to the surface of the cast-in-place steel template 31. During the construction process, concrete is poured into the cast-in-place steel template 31. After the concrete reaches the design strength, the cap beam 1 can be formed.

[0039] Working principle: During construction, the square clamp assembly is fitted onto the rectangular pier 2. The back frame is connected by the back frame flange and high-strength bolts 46 to form a stable frame. The vertical steel pipe poles 43 connect the three layers of back frame 41 into a whole, enhancing the overall rigidity. The back frame stiffening plate 48 prevents stress concentration damage at the corners. The vertical back ribs 42 strengthen the back frame and provide an installation base for the anti-slip friction panel 45. The anti-slip friction panel 45 contacts the outer wall of the rectangular pier 2, using friction to prevent the clamp assembly from sliding, ensuring that the clamp assembly is stably fixed on the pier, and providing a support base for the subsequent support assembly 5 and formwork support 32.

[0040] When installing the support assembly 5, the flange plates 541 on the left and right sets of support stiffening plates 55 are connected by high-strength bolts 542. The flange stiffening plates 543 enhance the strength and stability of the flange connection, ensuring that the connection between the upper chords 52 is firm, thereby ensuring the reliability of the overall structure of the support assembly 5 and enabling it to effectively transmit the load.

[0041] The support assembly 5 is hinged to the square clamp assembly via the diagonal lug 53 and the pin 47, thus connecting with the clamp assembly. The support diagonal rod 51 and the upper chord 52 are welded to form a stable structural system. The support stiffening plate 55 disperses the stress at the weld and prevents damage. The upper chord flange and high-strength bolts 54 facilitate installation and disassembly and ensure reliable connection. The transverse connecting rod 57 and the connecting system 56 increase the transverse stiffness and overall stability of the support assembly 5, enabling it to better bear the load. During the construction of the cap beam 1, the load transmitted by the formwork and support assembly 3 is evenly distributed to the upper chord 52 through the distribution beam 59, and then transmitted to the square clamp assembly and rectangular pier 2 by the support diagonal rod 51. After construction is completed, the formwork and support assembly 3 can be safely and smoothly unloaded by controlling the working state of the unloading block 58.

[0042] When constructing the cap beam 1, first erect the formwork support 32, and then install the cast-in-place steel formwork 31 on the formwork support 32. Due to its high strength, high rigidity and smooth surface, the cast-in-place steel formwork 31 provides a stable and reliable formwork structure for the concrete pouring of the cap beam 1. Concrete is poured inside the cast-in-place steel formwork 31. After the concrete reaches the design strength, the formwork and support components 3 are removed (by unloading block 58) to obtain the formed cap beam 1.

[0043] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
