Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, and in particular to a support device and a haunch beam formwork for haunch beams. Background Technology

[0002] In the construction of large public buildings and modern industrial plants, with the continuous increase in building spans and the ever-increasing load requirements, especially the profound impact of frame structure spans on structural design, the traditional beam design scheme using a uniform cross-sectional height has gradually revealed its limitations. Specifically, if the beam maintains the same cross-sectional height throughout the entire span, it will result in overly dense reinforcement at the beam supports. This not only poses a significant challenge to the construction process and increases construction difficulty, but also leads to a relatively low reinforcement ratio in the mid-span area of ​​the beam, thus affecting the overall economic efficiency of the structure.

[0003] Therefore, adopting a variable cross-section design, specifically by adding vertical haunches to areas with large bending moments at beam supports, becomes a more reasonable solution. This design can effectively control the reinforcement ratio at beam supports and optimize the structural stress performance.

[0004] Haunched beams, as a special type of variable cross-section beam structure, can be formed in building construction by obliquely raising the base of both steel and concrete beams. This can significantly improve the load-bearing capacity and seismic performance of the beam. Utility Model Content

[0048] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0049] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," "far," "near," "front," and "rear," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0050] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] The inventors discovered that during the use of haunched beams, due to their variable cross-section design, the formwork is tilted during installation, making conventional vertical or horizontal support methods unsuitable for reinforcement. This often results in poor reinforcement of the haunched beam side formwork. Furthermore, because the root inclination angles of the steel or concrete beams in the haunched area differ, traditional methods involving on-site cutting and splicing of supports and steel pipes present the following problems: angle adjustment relies on manual experience, resulting in low precision and efficiency; repeated disassembly and adjustment easily lead to material waste and hinder effective material reuse.

[0052] To address the aforementioned issues, the inventors developed a support device and a haunch beam template that can quickly adjust the angle, improve construction efficiency, and ensure support stability.

[0053] Example 1

[0054] See Figures 1-3This embodiment proposes a support device for haunched beam formwork, capable of supporting the haunched beam formwork. The support device includes: at least two lifting components 2, at least two support seats 3, two sets of steel pipe assemblies 4, a support assembly 5, and a reinforcing steel assembly 1. The reinforcing steel assembly 1 includes connecting bolts 12, two reinforcing steel bodies 11, and two support members 13. The ends of the two reinforcing steel bodies 11 are rotatably connected by the connecting bolts 12, forming an adjustable support structure. Here, the reinforcing steel bodies 11 can be made of various types of steel available in the prior art, as long as the ends of the two reinforcing steel bodies 11 can be rotatably connected by the connecting bolts 12. For example, the reinforcing steel bodies 11 can be made of... Figure 1 and Figure 3 The angle steel shown is used. The reinforcing steel body 11 is connected to the support member 13, which supports the haunch beam formwork located above it. At least one lifting assembly 2 is provided below each of the two support members 13. The support member 13 can be made of materials such as wood, bamboo, or carbon fiber, as is commonly used in the art. The lifting assembly 2 is located on the support member 5, which provides stable support for the lifting assembly 2. A bracket 3 is correspondingly provided to the lifting assembly 2. The upper end of the lifting assembly 2 is connected to the bracket 3, which has a receiving groove (not shown in the figure) for placing the steel pipe assembly 4, providing stable support for the steel pipe assembly 4. The steel pipe assembly 4 is placed in the receiving groove and abuts against the corresponding support member 13, providing additional support force for the haunch beam formwork and enhancing the stability of the structure.

[0055] In use, the lifting component 2 is controlled to lift and lower, which can drive the corresponding support 3 to lift and lower, thereby driving the corresponding reinforcing steel body 11 to rotate relative to another reinforcing steel body 11. The angle can be flexibly adjusted according to the tilt angle of the haunch beam template on site, so that the entire support device is adapted to the haunch beam template.

[0056] Compared to the traditional method of on-site cutting and splicing of materials such as support components 13 and steel pipes, the support device in this embodiment can achieve stepless adjustment of the inclination angle of the haunch beam formwork from 0° to 90° to meet the support requirements of haunch beam formwork at different angles. It has higher precision, can achieve effective reuse, and saves materials. Since the support device in this embodiment does not require repeated disassembly and angle adjustment, it will not cause material waste. At the same time, it eliminates the traditional cutting process of support component 13, effectively improving construction efficiency.

[0057] The support device in this embodiment can flexibly and quickly adjust the angle to match the haunch beam formwork, making it easy to operate and helping to improve construction efficiency and reduce construction costs. Simultaneously, the appropriate length of the reinforcing steel body 11 and support member 13 can be selected according to the size of the haunch beam formwork to adapt to different sizes of haunch beam formwork, improving applicability. Through the cooperation of the lifting assembly 2, the reinforcing steel body 11, the support member 13, and the steel pipe assembly 4, effective support for the haunch beam formwork is achieved, effectively solving the problems of unstable support of the haunch beam corner formwork and easy deformation and bursting during concrete pouring, which are detrimental to construction. This improves the overall rigidity of the haunch beam formwork during construction, ensuring safety and stability during the construction process. The support device in this embodiment is simple to operate, low in cost, reusable, safe, and efficient.

[0058] It is worth noting that this embodiment does not impose a specific limit on the number of reinforcing steel components 1. The number of reinforcing steel components 1 can be set according to the specifications of the haunch beam template or the required support capacity, as long as there is at least one lifting component 2 under each of the two support members 13. When a large number of reinforcing steel components 1 are set, multiple lifting components 2 can be set to ensure the support effect of the entire reinforcing steel component 1. Figure 1 An example of a reinforced steel assembly 1 with multiple intervals is provided, and two lifting assemblies 2 are provided below the support member 13 on the same side. The two lifting assemblies 2 are spaced apart along the width direction of the support member 13, and a set of steel pipe assemblies 4 are provided on the support 3 of the two lifting assemblies 2.

[0059] In one specific embodiment, see [reference] Figure 2 and Figure 3 The reinforcing steel component 1 also includes self-tapping screws 15. The reinforcing steel body 11 has connecting holes 14 evenly distributed along its length. The spacing of the connecting holes 14 can be set according to the support requirements. The specifications of the connecting holes 14 match the self-tapping screws 15. For example, a connecting hole 14 with a diameter of 4.2mm is adapted to an M4 self-tapping screw 15. The self-tapping screw 15 can pass through the connecting hole 14 and be directly screwed into the support member 13 to connect with it, achieving rapid fixation and thus achieving a stable connection between the reinforcing steel body 11 and the support member 13. The evenly spaced connecting holes 14 ensure uniform distribution of support force, avoid local stress concentration, and improve overall bending stiffness. The self-tapping screw 15's no-pre-drilling characteristic eliminates the need for pre-drilling or complex tools, enabling rapid installation or disassembly, significantly shortening construction time and reducing labor costs. The high-strength connection of the self-tapping screw 15 prevents loosening, improving the efficiency and safety of the haunched beam formwork support.

[0060] In one specific embodiment, see [reference] Figure 1 and Figure 2The support assembly 5 includes a disc-lock upright 51, a disc 53, and a disc-lock horizontal bar 52, wherein the disc-lock upright 51 is correspondingly arranged with the lifting assembly 2. The disc 53 is sleeved on the outside of the disc-lock upright 51, and multiple insertion holes (not shown in the figure) are opened around the circumference of the disc 53. The lifting assembly 2 is provided at the upper end of the disc-lock upright 51. The end of the disc-lock horizontal bar 52 is provided with a wedge-shaped pin (not shown in the figure) that matches the insertion hole. After the wedge-shaped pin is inserted into the insertion hole, the wedge-shaped pin connects with the insertion hole. The wedge-shaped structure of the wedge-shaped pin achieves axial and radial double locking to prevent loosening, thereby achieving the purpose of firmly connecting the disc-lock upright 51 and the disc-lock horizontal bar 52.

[0061] In one specific embodiment, see [reference] Figure 2 The lifting assembly 2 includes an adjustable lead screw 21 and an adjusting member 22. The adjusting member 22 is sleeved on the outside of the adjustable lead screw 21 and threadedly connected to it. The top end of the adjustable lead screw 21 is threadedly connected to the support 3, and the lower end of the adjustable lead screw 21 is inserted into the disc buckle upright 51 and threadedly connected to it. By controlling the adjusting member 22, the adjustable lead screw 21 can be rotated. The rotation of the adjustable lead screw 21 can be converted into linear motion, thereby raising and lowering the corresponding support 3, which in turn drives the corresponding reinforcing steel body 11 to rotate relative to another reinforcing steel body 11, adapting to the haunch beam template at different angles. Through the coordinated action of the adjustable lead screw 21, the adjusting member 22, and the support 3, efficient, precise, and safe lifting adjustment is achieved, and the included angle between the two reinforcing steel bodies 11 of the reinforcing steel assembly 1 can be precisely controlled to adapt to the haunch beam template at different angles.

[0062] In one specific embodiment, see [reference] Figure 2 The outer wall of the adjusting member 22 is provided with an operating end face (not shown in the figure). The operating end face serves as the force application point for rotating the adjusting member 22, providing the operator with a gripping and force application position. An anti-slip rubber sleeve (not shown in the figure) is fitted on the outer side of the operating end face to increase the friction of the operating end face and prevent slippage during manual adjustment.

[0063] In another embodiment, the lifting assembly 2 includes a screw jack, which can be replaced... Figure 1 and Figure 2 The adjustable screw 21 is used in the screw jack, with the bottom end of the screw jack fixedly connected to the disc-lock upright 51, and the upper end of the screw jack connected to the support 3. Alternatively, a hydraulic lifting cylinder can be used instead of the screw jack. The bottom end of the hydraulic lifting cylinder is fixedly connected to the disc-lock upright 51, and the upper end of the hydraulic lifting cylinder is connected to the support 3. The lifting method achieved by the screw jack and hydraulic lifting cylinder can refer to existing technologies. Using the screw jack and hydraulic lifting cylinder, quick lifting and adjustment can be achieved, and the included angle between the two reinforcing steel bodies 11 of the reinforcing steel assembly 1 can be precisely controlled to adapt to haunched beam templates at different angles.

[0064] In another embodiment, see Figure 1 and Figure 2 The receiving groove of the support 3 is U-shaped, and a through-hole fastening bolt (not shown in the figure) is provided in the receiving groove to fix the steel pipe assembly 4. The axis of the fastening bolt is perpendicular to the axis of the steel pipe assembly 4 and perpendicular to the lifting assembly 2. Figure 2 In the horizontal direction, the axis of the fastening bolts is aligned to ensure a uniform distribution of clamping force. The inner wall of the receiving groove is equipped with an anti-slip rubber pad (not shown in the figure) to prevent detachment. Through the synergistic effect of the fastening bolts and the anti-slip rubber pad, efficient and safe fixing of the steel pipe assembly 4 is achieved.

[0065] In another embodiment, see Figure 1 and Figure 2 The steel pipe assembly 4 includes multiple horizontally parallel steel pipe bodies 41, which are connected to corresponding support members 13 via U-shaped clips (not shown in the figure). The U-shaped clips enable a quick and stable connection between the steel pipe bodies 41 and the support members 13, preventing displacement of the steel pipe bodies 41 during use and ensuring the overall support effect of the device. Furthermore, the U-shaped clip connection method is suitable for steel pipe bodies 41 and support members 13 of different specifications, facilitating on-site adjustments and offering high flexibility.

[0066] In another embodiment, see Figure 2 and Figure 3 The contact surface between the support member 13 and the reinforcing steel body 11 is provided with anti-slip serrations (not shown in the figure). The serration structure increases the coefficient of friction between the contact surface between the support member 13 and the steel body, preventing slippage and effectively providing a reliable connection between the support member 13 and the reinforcing steel body 11, thereby ensuring the stability and safety of the entire support device.
