[0027] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0028] like Figures 1 to 6 As shown, a standardized support beam includes a main beam 1 and a small beam 2, wherein the main beam 1 is provided with a first limiting portion 11 for limiting the installation position of the small beam 2, and the small beam 2 is provided with a second limiting portion 21 detachably connected to the first limiting portion 11, and when the second limiting portion 21 is connected to the first limiting portion 11, the top plane of the main beam 1 is flush with the top plane of the small beam 2.

[0029] Specifically, in some embodiments, the formwork frame used in the construction process is a temporary support system for supporting the concrete structure during construction. The formwork frame can be composed of a main beam and a small beam. The main beam 1 and the small beam 2 can both adopt steel profiles of different structures such as U-shaped steel, rectangular steel, tubular steel, and I-shaped steel. There is no need to design the profile structure separately, the material is easy to obtain, the cost is controllable, and the structure is stable. The main beam 1 is provided with a first limiting portion 11 for limiting the installation position of the small beam 2, and the small beam 2 is provided with a second limiting portion 21 for detachably connecting to the first limiting portion 11. The first limiting portion 11 is provided with a notch connected to the outside world, and the notch faces It is set in the direction of the top of the main beam 1, and the second limiting portion 21 extends from top to bottom into the first limiting portion 11 so that the main beam 1 and the small beam 2 have the top plane of the main beam 1 flush with the top plane of the small beam 2. After the connection, since the second limiting portion 21 extends from top to bottom into the first limiting portion 11, the second limiting portion 21 is restricted from displacement to the left, right, bottom, front and rear, so that the connection between the main beam 1 and the small beam 2 is more stable. The detachable connection design is adopted, which can be repeatedly disassembled and installed to adjust the installation interval of the small beam. It can also be conveniently disassembled and transported to different construction sites to adapt to different construction scenes.

[0030] like Figures 1 to 6 As shown, the second limiting portion 21 includes a wing plate 22 extending from the center of one end of the small beam 2 toward the left and right sides and the bottom, and the wing plate 22 is inserted into the first limiting portion 11 to be detachably connected to the first limiting portion 11.

[0031] Specifically, in some embodiments, the wing plate 22 is used to extend into the first limiting portion 11 so that the main beam 1 and the small beam 2 can be detachably connected. The wing plate 22 extends from the center of one end of the small beam 2 toward the left and right sides and the bottom to form a U-shaped plate structure. The tops of the left and right sides of the wing plate 22 are flush with the top plane of the small beam 2. The wing plate 22 can be fixedly connected to the small beam 2 by welding or integral molding, so that the wing plate 22 and the small beam 2 are more stable. The wing plate 22 has a simple structure and a simple process, which ensures that the second limiting portion 21 is restricted from displacement toward the left, right, bottom, front and rear sides, so that the connection between the main beam 1 and the small beam 2 is more stable.

[0032] like Figures 1 to 6 As shown, the first limiting portion 11 is provided with a matching groove 12 for the second limiting portion 21 to extend into, and the groove width of the matching groove 12 is greater than the installation width of the wing plate 22 .

[0033] Specifically, in some embodiments, the first limiting portion 11 is provided with a matching groove 12 for the second limiting portion 21 to extend into, and the matching groove 12 is used to install the wing plate 22. If the groove body width of the matching groove 12 is too large, the limiting effect cannot be guaranteed to meet the stability of construction. If the groove body width of the matching groove 12 is too small, it is difficult to insert the wing plate 22, which is not convenient for workers to use and affects the construction efficiency. Preferably, the groove body width of the matching groove 12 can adopt a size range of 0-10mm greater than the installation width of the wing plate 22. With such a design, the wing plate 22 can be smoothly inserted during installation, and can also have sufficient limiting effect to meet the stability of construction and meet the construction requirements of the construction site.

[0034] like Figures 1 to 6 As shown, the first limiting portion 11 is provided with a limiting notch 13 for limiting the extending position of the small beam 2 , and the small beam 2 is installed in the limiting notch 13 so that the top plane of the small beam 2 is flush with the top plane of the main beam 1 .

[0035] Specifically, in some embodiments, the limiting groove 13 is used to limit the installation height of the small beam 2. After the second limiting portion 21 extends into the first limiting portion 11, the outer side of the small beam 2 is connected with the limiting groove 13, and the bottom of the limiting groove 13 supports the bottom of the small beam 2, thereby limiting the installation position of the top of the small beam 2. After the installation is completed, the top of the small beam 2 is flush with the top plane of the main beam 1, avoiding the phenomenon of plane drop between the main beam 1 and the small beam 2 after the installation is completed. The phenomenon of plane drop can easily cause construction accidents and there are construction hazards. The limiting setting that the top of the small beam 2 is flush with the top plane of the main beam 1 can effectively avoid the occurrence of plane drop phenomenon and reduce safety accidents caused during construction.

[0036] like Figures 1 to 6 As shown, the main beam 1 is provided with a plurality of first limiting portions 11 with equal intervals, and the first limiting portions 11 are arranged along the length direction of the main beam 1 .

[0037] Specifically, in some embodiments, the first limiting portion 11 is arranged on the side of the main beam 1 along the length direction of the main beam 1, and the notches of the first limiting portion 11 are all set toward the upper side. A plurality of equally spaced first limiting portions 11 can be used to install a plurality of equally spaced small beams 2. In conjunction with the detachable connection between the main beam 1 and the small beam 2, the installation position of the small beam 2 can be conveniently adjusted to avoid raised obstacles on the construction site or adapt to different construction requirements and construction environments, making it convenient for workers to use.

[0038] like Figures 1 to 6 As shown, the bottom of the first limiting portion 11 is flush with the bottom plane of the main beam 1 .

[0039] Specifically, in some embodiments, in order to stably place the main beam 1 and better locate the installation position of the small beam 2, the bottom of the first limiting portion 11 is flush with the bottom plane of the main beam 1. With such a design, the small beam 2 can be installed and the gravity exerted on the first limiting portion 11 can be transferred to the bottom contact plane of the main beam 1, thereby preventing the first limiting portion 11 from being suspended on the outer side of the main beam 1, affecting the force on the first limiting portion 11, and reducing the possibility of the first limiting portion 11 loosening and breaking due to excessive force, thereby improving the stability of the main beam 1 structure, improving the stability of the connection between the main beam 1 and the small beam 2, reducing safety hazards, and reducing safety risks.

[0040] like Figures 1 to 6 As shown, the first limiting portions 11 are symmetrically arranged on both sides of the main beam 1 .

[0041] Specifically, in some embodiments, the first limiting portion 11 is symmetrically arranged on the left and right sides of the outer side of the main beam 1 along the length direction of the main beam 1, and the notches of the first limiting portion 11 are all facing the upper side of the main beam 1. With such a design, more small beams 2 can be installed on both sides of the main beam 1 at the same time, and the main beam 1 can be installed at both ends of the small beam 2 respectively, and the main beam 1 and the small beam 2 are installed alternately in sequence to form a support beam network with a larger layout area to adapt to a larger construction site and meet more construction requirements.

[0042] like Figures 1 to 6 As shown, the second limiting portions 21 are symmetrically arranged at two ends of the small beam 2 .

[0043] Specifically, in some embodiments, the second limiting portions 21 are symmetrically arranged at the two ends of the small beam 2 to ensure that the second limiting portions 21 at the two ends of the small beam 2 can have a unified structure, which is convenient for installing the main beam 1 with the same orientation at the two ends of the small beam 2. If the second limiting portions 21 at the two ends of the small beam 2 are not symmetrically arranged, it may cause installation confusion, deviation in the limiting effect, and inability to complete the installation, affecting the construction progress and the difficulty of installation. The design of symmetrically arranging the second limiting portions 21 at the two ends of the small beam 2 can expand the application scope of the small beam 2, and it is no longer limited to a single end that can be installed on the main beam 1. By alternately installing the main beam 1 and the small beam 2 in sequence, a support beam network with a larger layout area is formed to adapt to a larger construction site and meet more construction requirements.

[0044] like Figures 1 to 4 as well as Figure 6 As shown, the main beam 1 is a U-shaped structural steel, the small beam 2 is a rectangular steel tube, the main beam 1 is provided with a steel body opening 14 arranged toward the lower side, and the notch of the matching groove 12 is arranged toward the opposite direction of the steel body opening 14 .

[0045] Specifically, in some embodiments, the main beam 1 adopts a "U"-shaped structure as the main force-bearing structure of the steel body. The steel body opening 14 of the "U"-shaped structure of the main beam 1 is set to the lower side, and the notch of the first limiting portion 11 is set in the opposite direction of the steel body opening 14. With such a design, the "U"-shaped structure is not easy to bend, and the appropriate steel thickness is selected according to the requirements of the project. In addition to ensuring that the main beam 1 meets the load-bearing structure required by the project, it can also save steel loss, simplify construction steps, reduce construction weight, and facilitate pouring of fillings, which is convenient for workers to construct and improves construction efficiency.

[0046] Specifically, in some embodiments, the small beam 2 adopts a hollow rectangular steel pipe structure as the main force-bearing structure of the steel body. The small beam 2 is a "mouth"-shaped structure extending toward both ends. The second limiting portion 21 is fixedly connected to both ends of the small beam 2 by welding or integral molding. By adopting such a design, the characteristic of the steel pipe structure that it is not easy to bend is utilized, and the appropriate steel thickness is selected according to the requirements of the project. In addition to ensuring that the small beam 2 meets the load-bearing structure required by the project, it can also save steel loss, simplify the construction steps, reduce the construction weight, facilitate workers' disassembly and assembly, and improve construction efficiency.

[0047] like Figures 1 to 6 As shown, a plurality of equally spaced small beams 2 are arranged between two parallel main beams 1 , and the small beams 2 are vertically arranged on one side of the main beam 1 .

[0048] Specifically, in some embodiments, in order to better combine and assemble the main beam 1 and the small beam 2, a plurality of small beams 2 with equal intervals can be arranged between two parallel main beams 1, and the small beam 2 is vertically arranged on one side of the main beam 1. The main beam 1 and the small beam 2 are modularly and uniformly combined and assembled together. According to the requirements and needs of the construction site, the number of main beams 1 and small beams 2 can be increased or decreased to arrange them in this combined assembly manner, thereby effectively expanding the layout area of ​​the support beams, improving the connection stability of the support beams, and improving the stability of the overall structure. Modular assembly is used to improve construction efficiency and reduce construction costs.

[0049] like Figures 1 to 6 As shown, the specific implementation of Example 1 of the utility model is as follows:

[0050] The steel body opening 14 of the "U"-shaped structure of the main beam 1 is set to face downward, and the side of the small beam 2 without the wing plate 22 is set to face upward. The wing plate 22 extends into the first limiting portion 11 and is connected to the matching groove 12. The outer side of the small beam 2 is connected to the limiting groove 13. When the small beam 2 contacts the bottom of the limiting groove 13 or the wing plate 22 contacts the bottom of the matching groove 12, the top plane of the main beam 1 is flush with the top plane of the small beam 2, and the installation between the main beam 1 and the small beam 2 is completed.

[0051] like Figures 1 to 6 As shown, the specific implementation of Example 2 of the utility model is as follows:

[0052] Different from Example 1, a plurality of first limiting portions 11 with equal intervals arranged along the length direction of the main beam 1 are provided on both sides of the main beam 1 of Example 2, and second limiting portions 21 are symmetrically arranged at both ends of the small beam 2. The second limiting portions 21 of the plurality of small beams 2 are respectively installed on the corresponding first limiting portions 11, so that the small beams 2 are arranged according to the intervals of the first limiting portions 11, and the main beam 1 extends into the first limiting portions 11 through the second limiting portions 21 to be matched and connected to the two ends of the small beam 2.

[0053] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this. Any technical extension or re-creation made based on the utility model is protected by the utility model. The protection scope of the utility model shall be based on the claims.
