[0030] 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.

[0031] See also Figure 1-4 The present embodiment provides an adjustable formwork support component for the web and flange plates of a cast-in-place box beam, comprising a support portion 1 arranged on the ground, a bottom cross beam 2 arranged on the support portion 1, a top cross beam 3 for carrying the web plate, a longitudinal beam 4 for carrying the flange plate, an adjustable vertical rod 5 and an adjustable diagonal rod 6, a top cross beam 3 is arranged above the bottom cross beam 2, two ends of the top cross beam 3 are connected to the bottom cross beam 2 by the longitudinal beam 4 and the adjustable vertical rod 5 respectively, a closed support area is formed between the bottom cross beam 2, the top cross beam 3, the longitudinal beam 4 and the adjustable vertical rod 5, and the beam body of the longitudinal beam 4 and the beam body of the bottom cross beam 2 are both The supporting columns, bottom cross beam 2, top cross beam 3, longitudinal beam 4, adjustable vertical rod 5 and adjustable diagonal rod 6 are connected by adjustable diagonal rod 6 to form a stable adjustable formwork support structure. The web formwork and flange plate formwork are adjusted in position by adjusting diagonal rod 6 and adjustable vertical rod 5. In terms of material selection, the supporting columns, bottom cross beam 2, top cross beam 3, longitudinal beam 4, adjustable vertical rod 5 and adjustable diagonal rod 6 in the support components are all made of high-strength and corrosion-resistant steel. The formwork material is mostly made of bamboo plywood to meet the construction requirements and improve durability. The support part 1 includes columns and top supports. The cross beam connects the columns and the top supports to provide support for the formwork.

[0032] One point that needs to be explained is that, by using the adjustable vertical rod 5 and the adjustable diagonal rod 6, the structure allows the user to flexibly adjust the height and angle of the bracket according to actual needs. This adjustability enables the formwork bracket to adapt to box beams of different heights and shapes, ensuring the accurate fit of the formwork, and the closed support area formed between the bottom cross beam 2, the top cross beam 3, the longitudinal beam 4 and the adjustable vertical rod 5 provides a stable support foundation for the bracket, making the entire structure more stable and avoiding deformation or displacement of the formwork caused by unstable brackets. In addition, due to the adjustability, the formwork bracket can be adjusted according to the specific size of the box beam, avoiding the traditional bracket being too compact or too sparse. The problem of sparseness is solved, thereby reducing the usage and waste of materials, and the adjustable bracket structure makes the installation and disassembly of the template more convenient and quick, improves the construction efficiency, and the construction personnel can quickly adjust the bracket as needed, shortens the construction period, and reduces the labor cost; furthermore, the coordinated use of the adjustable diagonal rod 6 and the adjustable vertical rod 5 makes the adjustment of the bracket more precise, and can accurately control the position of the template, thereby ensuring the dimensional accuracy and quality of the web and flange plates of the box beam. This adjustable template bracket structure is not only suitable for the web and flange plates of cast-in-place box beams, but can also be used in the construction of other similar structures, and has good versatility and adaptability.

[0033] Currently, the same beam-slab structure may appear repeatedly in projects such as bridges and high-rise buildings. Therefore, the formwork supports for the web and flange plates of cast-in-place box girders mostly adopt a fixed design. The use of a fixed design can simplify the construction process. However, in order to ensure stability during the construction process, the fixed-design formwork supports usually require more materials to ensure stability, which may lead to material waste. At the same time, since the supports are difficult to adjust, some supports may be too compact or too sparse, further exacerbating material waste.

[0034] In order to solve the above problems, a support part 1 is placed on the ground, a bottom cross beam 2 is arranged on the support part 1, a top cross beam 3 is arranged above the bottom cross beam 2, and the two ends of the top cross beam 3 are connected to the bottom cross beam 2 by longitudinal beams 4 and adjustable vertical rods 5 respectively, a closed support area is formed between the bottom cross beam 2, the top cross beam 3, the longitudinal beam 4 and the adjustable vertical rods 5, the beam body of the longitudinal beam 4 and the beam body of the top cross beam 3, and the beam body of the longitudinal beam 4 and the beam body of the bottom cross beam 2 are all connected by adjustable diagonal rods 6, the supporting columns, the bottom cross beam 2, the top cross beam 3, the longitudinal beam 4, the adjustable vertical rods 5 and the adjustable diagonal rods 6 together constitute a stable adjustable formwork support structure, the web formwork and the flange plate formwork are both adjusted in position by the adjustable diagonal rods 6 and the adjustable vertical rods 5, so as to solve the problem that the formwork supports of the web and flange plates of the cast-in-place box girder in the prior art are difficult to adjust, and some supports may be too compact or too sparse, exacerbating the problem of material waste.

[0035] In order to provide greater flexibility and efficiency for the construction of cast-in-place box beams, while improving the safety and economy of the construction, in one embodiment, a plurality of adjustment holes 7 are provided on the bottom cross beam 2, the top cross beam 3 and the longitudinal beam 4, and the two ends of the adjustable vertical rod 5 are respectively connected to any one of the adjustment holes 7 on the bottom cross beam 2 and the top cross beam 3, and the two ends of the adjustable diagonal rod 6 between the beam body of the longitudinal beam 4 and the beam body of the top cross beam 3 are respectively connected to any one of the adjustment holes 7 on the longitudinal beam 4 and the top cross beam 3, and the two ends of the adjustable diagonal rod 6 between the beam body of the longitudinal beam 4 and the beam body of the bottom cross beam 2 are respectively connected to any one of the adjustment holes 7 on the longitudinal beam 4 and the bottom cross beam 2, and the adjustment holes 7 on the bottom cross beam 2, the top cross beam 3 and the longitudinal beam 4 are connected to the adjustable vertical rod 5 and the adjustable diagonal rod 6 through a hinge pin 8, and an adjustable angle-adjustable movable triangular support is formed between the adjustable diagonal rod 6, the bottom cross beam 2 or the top cross beam 3 and the longitudinal beam 4;

[0036] By providing a plurality of adjustment holes 7 on the bottom cross beam 2, the top cross beam 3 and the longitudinal beam 4, the adjustable vertical rod 5 and the diagonal brace can be connected to any of the adjustment holes 7, so that the height and angle of the bracket can be flexibly adjusted according to construction needs to adapt to box beam structures of different shapes and sizes. Through the connection of the hinge pin 8, the adjustable diagonal brace 6, the bottom cross beam 2 or the top cross beam 3, and the longitudinal beam 4 can form an adjustable angle movable triangular support, which enables the bracket to be adjusted according to actual construction requirements to adapt to different construction environments, and the design of the adjustable diagonal brace 6 enhances the overall stability of the bracket. By forming a triangular support, various loads in the construction process can be effectively dispersed and borne. Due to the flexibility and adjustability of the bracket, the construction site can be set up and adjusted more quickly and conveniently, which greatly improves the construction efficiency. Due to its high adaptability and reusability, this bracket system can reduce the demand for special brackets, thereby reducing costs;

[0037] In addition, the adjustment of the web template is mainly achieved through the adjustable diagonal rod, the adjustment hole 7 and the hinge pin 8. The adjustable diagonal rod and the adjustable vertical rod 5 can adjust the height of the template to ensure that the template corresponds accurately to the designed position of the web. The web template and the flange template are respectively connected to the bottom cross beam 2 and the longitudinal beam 4 through connectors to prevent displacement during the pouring process. The adjustment of the flange template takes into account the inclination angle, height and lateral stability of the template. This component adopts the adjustable vertical rod 5 and the adjustable diagonal rod in conjunction with the adjustment hole 7 to form an adjustable angle movable triangular support frame. The precise adjustment of the template is achieved through the coordinated use of the adjustable diagonal rod, the adjustment hole 7 and the hinge pin 8, so the height and inclination angle of the template can be precisely adjusted to ensure the accurate correspondence between the template and the designed positions of the web and flange plates, thereby improving the pouring quality. The design greatly simplifies the adjustment process through the mechanized adjustment method, and considering that the template is easily affected by the pressure of concrete and causes displacement during the pouring process, this design effectively solves the problem of template displacement by enhancing the connection stability and adopting a triangular support frame, and has significant advantages in improving construction quality, safety and efficiency.

[0038] A method for using an adjustable formwork support component for a web and flange plate of a cast-in-place box beam comprises the following steps:

[0039] S1: First, determine the position and size of the web formwork and flange plate formwork according to the design drawings, ensure that the installation position and size of the formwork are consistent with the design drawings, meet the structural design requirements, avoid construction errors, reduce rework, and improve construction quality;

[0040] S2: Then the bottom cross beam 2 is set up at the support top position. The bottom cross beam 2 is the foundation of the support. Correct setting can ensure the stability and load-bearing capacity of the support, improve the stability of the support, ensure construction safety, and avoid construction accidents caused by unstable support;

[0041] S3: Assemble the adjustable bracket according to the determined size and position of each part of the cast-in-place beam. The adjustable bracket can be adjusted according to actual needs to adapt to cast-in-place beams of different sizes and shapes, improve the adaptability of the bracket, reduce the cost of customized brackets, and improve construction efficiency;

[0042] S4: Adjust the web template, by connecting the adjustable diagonal rod and the adjustable vertical rod 5 to the adjustment holes 7 at different positions, respectively, so as to adjust the height of the web template, to ensure that the web template corresponds precisely to the position to be designed for the web, and the height adjustment of the web template needs to be precise, to ensure that the template corresponds precisely to the designed position of the web, to ensure the installation accuracy of the web template, and to avoid concrete pouring defects caused by inaccurate templates;

[0043] S5: Adjust the flange plate template, use the adjustable vertical rod 5 and the adjustable diagonal rod in conjunction with the adjustment hole 7, connect the adjustable vertical rod 5 and the adjustable diagonal rod to the adjustment holes 7 at different positions respectively, and form a movable triangular support frame with adjustable angles, and realize precise adjustment of the flange plate template through the articulation and tension-compression principle; the flange plate template needs to be able to adjust the angle and height to meet the needs of flange plates of different shapes and sizes, provide greater adjustment flexibility, ensure the precise installation of the flange plate template, and improve the adaptability of the template;

[0044] S6: After the adjustable support is erected as a whole, the formwork support is adjusted by using construction tools such as a level and a level ruler. After the overall erection is completed, it is necessary to ensure the horizontality and stability of the support to meet the construction quality requirements. Through precise adjustment, the overall stability of the formwork support is ensured, the deviation during the construction process is reduced, and the overall quality of the concrete structure is improved.

[0045] In order to further improve the construction efficiency and ensure the construction safety, in one embodiment, the web formwork and the flange plate formwork are respectively connected to the bottom cross beam 2 and the longitudinal beam 4 by connecting pieces to prevent displacement during the pouring process. The adjustment of the flange plate formwork needs to consider the inclination angle, height and lateral stability of the formwork. The web formwork and the flange plate formwork are connected to the bottom cross beam 2 and the longitudinal beam 4 by connecting pieces to ensure that the formwork will not be displaced during the pouring process, thereby ensuring that the geometric size and shape of the box beam meet the design requirements. Considering the adjustment of the inclination angle in the design of the flange plate formwork can make the formwork adapt to the slope of the box beam with different designs and meet the diverse construction needs. By adjusting the height of the formwork, It can adapt to the changes in the height of different box girders and improve the application range and flexibility of the formwork. Through this connection and support design, the lateral stability of the formwork is enhanced to prevent deformation or damage of the formwork due to the lateral pressure of concrete during the pouring process. The design of the adjustable formwork support component makes the installation and adjustment of the formwork more convenient, reducing the time and labor costs in construction, and can also prevent accidents caused by displacement or damage of the formwork. Since the stability and accuracy of the formwork are improved, the poured concrete structure will also be more compact and uniform, improving the strength and durability of the overall structure. This design can be applied to the pouring of box girders of different types and sizes, improving versatility and adaptability.
