Description

Technical Field

[0002] In existing building construction, especially in the construction of cast-in-place beams, since the size and weight of cast-in-place beams are large, a buckle bracket is usually used as a load-bearing structure to connect with the pier body, and the buckle bracket adopts a modular design, in which the vertical rods, horizontal rods, diagonal rods and other components of the buckle bracket are connected by screws or welding to form a stable triangular structure. This structural design can effectively resist horizontal and vertical loads and provide a solid foundation for the cast-in-place beam.

[0003] However, when the current disc-shaped bracket is connected to the pier body as a load-bearing structure, there are still some problems in construction: since the disc-shaped bracket and the pier body are connected by screws or welding, the torque and force during the adjustment process are often large, and a single person may find it difficult to bear or control. Therefore, multiple people are required to cooperate during the adjustment process, which is inconvenient to operate. In addition, fixing with screws or welding will result in more connection nodes, which is prone to stress concentration and relatively poor stability of the connection parts. During the construction process, factors such as vibration may cause the connection parts to loosen, further affecting the stability of the structure. Therefore, it is particularly important to develop a connection system that is highly adjustable, stable and reliable, and easy to install to ensure a safe and reliable connection between the bracket and the pier body.

DETAILED DESCRIPTION

[0023] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0024] See also Figure 1-2 The present embodiment provides an adjustable connector between a cast-in-place beam support and a pier body, comprising a limit frame, an adjustable component for adjusting the size of the limit frame, and a locking component. The limit frame is sleeved on the pier body, and the adjustable component presses the limit frame and the pier body together by adjusting the size of the limit frame. The locking component is used to lock the pressed state of the limit frame and the pier body. The limit frame, the adjustable component, the locking component and the pier body together form a clamp structure. Through the adjustable component, construction personnel can adjust the size of the limit frame according to actual needs to adapt to pier bodies of different sizes. The compression between the limit frame and the pier body can provide high stability, which helps to ensure the stability of the beam and the pier body during the construction process and prevent structural damage caused by displacement or other factors. The locking component is designed to be locked after the limit frame and the pier body are pressed together, which can further ensure the fixation of the structure and improve the safety of construction. The design of this connector makes construction more convenient and improves construction efficiency. There is no need to use complex installation procedures or tools, which saves construction time and labor costs.

[0025] At present, in the existing building construction, especially in the construction of cast-in-place beams, since the size and weight of cast-in-place beams are large, a buckle bracket is usually used as a load-bearing structure to connect with the pier body, and the buckle bracket adopts a modular design, wherein the vertical rod, horizontal rod, diagonal rod and other components of the buckle bracket are connected by screws or welding to form a stable triangular structure. This structural design can effectively resist the horizontal and vertical loads and provide a solid foundation for the cast-in-place beam. However, when the current buckle bracket is connected to the pier body as a load-bearing structure, there are still some problems in construction: since the buckle bracket and the pier body are connected by screws or welding, the torque and force during the adjustment process are often large, and a single person may be difficult to bear or control. Therefore, multiple people are required to cooperate during the adjustment process, which is inconvenient to operate, and the screw or welding connection method will result in more connection nodes, which is easy to produce stress concentration, resulting in relatively poor stability of the connection part. During the construction process, due to factors such as vibration, the connection part may become loose, further affecting the stability of the structure.

[0026] In order to solve the above problems, in this embodiment, the limit frame is sleeved on the pier body, and the adjustable component adjusts the size of the limit frame to press the limit frame and the pier body together. The locking component is used to lock the limit frame and the pier body in a pressed state. The limit frame, the adjustable component, the locking component and the pier body together form a clamp structure, which can flexibly adapt to pier bodies of different heights and shapes, improve construction adaptability, and solve the problem of inconvenient adjustment and insufficient flexibility caused by the connection method of screws or welding between the buckle bracket and the pier body in the prior art. In addition, when assembling and connecting, it can be selected according to the size, type and specification of the pier column actually used, which has high adaptability and flexibility, and the connecting material is easy to disassemble, which can avoid the trouble of dismantling and material waste, and can be recycled and reused.

[0027] For square piers or straight-arm vase piers, size mismatch problems may be encountered during the manufacturing or installation of the square piers or straight-arm vase piers. In order to solve this problem, in one embodiment, the limit frame is a rectangular frame with adjustable size, and the two opposite sides of the rectangular frame are adjusting screw rods 1. The adjustable component includes a plurality of threaded steel pipes 2, a first connecting plate 4 and a connecting steel pipe 11 arranged on the adjusting screw rod 1. The plurality of threaded steel pipes 2 are vertically connected to the connecting steel pipe 11 through the first connecting plate 4, respectively. The connecting steel pipe 11 is provided with an adjusting thread 10 for ensuring the stability of the connection. The locking component includes a first connecting pin 3, and the first connecting plate 4 is connected to the threaded steel pipe 2 through the first connecting pin 3; the size of the limit frame is adjustable, which means that it can adapt to piers or vases of different sizes and shapes, which increases the versatility and applicability of the component. The edge is set as an adjusting screw rod 1, which can achieve precise size adjustment, so that the limit frame can be fine-tuned as needed to achieve the best connection state. Through the threaded steel pipe 2 and the adjusting thread 10, precise size control can be achieved to ensure the accuracy and stability of the connection between components. The threaded steel pipe 2 and the connecting steel pipe 11 in the design are easy to install and disassemble, convenient for maintenance and replacement, and the adjusting thread 10 can also ensure the stability of the connection to avoid loose connection due to vibration or external force. The adjustable design reduces the need to prepare components of various specifications to adapt to different sizes, thereby saving materials and costs. In addition, through the use of the first connecting pin 3 in the locking assembly, the stability of the connection part is ensured, and the structural safety risk caused by loose connection is avoided. This design provides more flexibility to meet the special requirements of specific projects.

[0028] Since the pier body of the cast-in-place beam may be a square pier or a straight-arm vase pier, it may also be a cylindrical pier or a pier body with an arc segment. For the cylindrical pier or the pier body with an arc segment, if stability needs to be ensured, a limit frame different from that of the square pier or the straight-arm vase pier needs to be adopted. In this regard, in one embodiment, the limit frame is an arc steel plate 5 with adjustable size, and the adjustable components include the arc steel plate 5, a support rod 12, a connecting rod 8, a first connecting plate 4 and a connecting steel pipe 11. The two ends of the connecting rod 8 are respectively connected to the outer wall of the arc steel plate 5 and the support rod 12, and the center of the outer wall of the arc steel plate 5 is connected to the support rod 12 through a locking component. The connecting steel pipe 11 is vertically connected to the support rod 12 through the first connecting plate 4. The arc steel plate 5 includes two arc blocks, and the pier body is located between the two arc blocks. Both ends of the support rod 12 are provided with a plurality of adjustment holes, and the connecting rod 8 is connected to any of the adjustment holes. The connecting rod 8 is connected to the outer wall of the arc block through the second connecting plate 7.

[0029] It should be noted that the size of the limit frame can be achieved by adjusting the arc steel plate 5. In fact, the two arc blocks of the arc steel plate 5 are symmetrically designed. Figure 1Only half of the arc steel plate 5 is drawn, and the other symmetrical half is not drawn, and the remaining parts connected to the arc steel plate 5 are also symmetrically distributed on the other half of the symmetrical arc steel plate 5. In order to adapt to cylindrical piers or arc segment piers of different sizes, the connecting rod 8 can be connected to any adjusting hole through the adjusting hole on the support rod 12, which allows the limit frame to be adjusted in the height direction to adapt to cylindrical piers of different heights. The locking assembly between the arc steel plate 5 and the support rod 12 ensures that the limit frame can remain stable after adjustment and is not easy to shake, thereby improving the safety of the overall structure. The modular design makes the installation and disassembly of the limit frame more convenient and improves the construction efficiency. Since the limit frame can be adjusted in size as needed, unnecessary material waste can be reduced.

[0030] In addition, the adjusting thread 10 is on the connecting steel pipe 11. By rotating the adjusting screw rod 1, the threaded steel pipe 2 can move along the screw rod, thereby adjusting the size of the limit frame to achieve compression with the pier body, which can ensure better contact and fixation between the beam support and the pier body to meet different construction requirements. In addition, the adjusting thread 10 can provide precise adjustment, so that the connection between the limit frame and the pier body is tighter, reducing the problem of unstable connection caused by excessive or small gaps. The adjusting thread 10 can also increase the contact area between the connecting steel pipe 11 and the pier body, thereby improving the bearing capacity of the connection part, making the entire structure more stable and able to withstand greater loads. At the same time, the adjusting thread 10 can be adjusted in real time during the connection process to avoid accidents caused by loose connection and improve construction safety. By adjusting the thread 10, construction personnel can easily and quickly adjust the connection state between the limit frame and the pier body to improve construction efficiency. The design of the adjusting thread 10 makes the connection structure more solid, which helps to improve the reliability and stability of the entire cast-in-place beam support system.

[0031] In order to further improve the construction efficiency while ensuring stability, in one embodiment, the locking assembly includes a first connecting pin 3 and a second connecting pin 6, and both ends of the connecting rod 8 are respectively connected to the first connecting plate 4 and the second connecting plate 7 through the first connecting pin 3, and the center of the outer wall of the arc block is connected to the support rod 12 through the second connecting pin 6. The arc steel plate 5, the support rod 12, the connecting rod 8, the first connecting plate 4, the second connecting plate 7, the connecting steel pipe 11, the first connecting pin 3 and the second connecting pin 6 are all made of high-strength materials. All components are made of high-strength materials and can withstand large loads and vibrations to ensure the stability and safety of the structure. The use of the second connecting pin 6 allows the connection component to flexibly adjust its position to adapt to cylindrical piers or arc segments of different diameters. The connection design makes the installation process of the component quick and simple, thereby improving the construction efficiency. Since the components are connected by pins, it is convenient to inspect and replace damaged parts, thereby reducing the maintenance cost. The connection component is suitable for cylindrical piers of various shapes and sizes. The pier bodies of cylindrical piers or arc segments have irregular shapes, and special connection methods are required to ensure the continuity and integrity of the structure. The use of high-strength materials and high-strength connection methods can enhance the stability and bearing capacity of the entire structure. The connecting pins between the arc block and the support rod 12 can effectively prevent structural deformation caused by uneven force.

[0032] In addition, cylindrical piers may bear large loads in engineering. This design meets the strength requirements by using high-strength materials and high-strength connections. Traditional connection methods require screws or welding. The design here simplifies the construction process and improves construction efficiency. The use of pin connection makes maintenance and inspection easier and extends the service life of the structure.
