[0022] The present invention will be further described in detail below with reference to embodiments:

[0023] like Figures 1-4 As shown, this utility model provides a guardrail for a cap beam operating platform, including a cap beam 1. Three sets of equidistantly distributed triangular steel frames 2 are fixedly installed at both ends of the cap beam 1. A connecting component 3 is provided at the upper end of the triangular steel frame 2, and a guardrail mechanism 4 is installed at the upper end of the connecting component 3.

[0024] The upper surface of the cap beam 1 is provided with three sets of fitting grooves 5 at equal intervals. The middle part of the triangular steel frame 2 is provided with a through hole 6. The interior of the through hole 6 and the through hole 3 are movably inserted into the exterior of the mounting bolt 33. They are matched with the support frame 31 through the fitting grooves 5 and are movably installed.

[0025] In this design, the dimensions of the fitting groove 5 are matched with those of the support frame 31, which ensures the stability of the support frame 31.

[0026] like Figure 3 As shown, the connecting component 3 includes a support frame 31. The lower end of the support frame 31 is movably connected to the top surface of the upper end of the cover beam 1. Both the front and rear ends of the support frame 31 are provided with through holes 32. The through holes 32 are movably inserted with mounting bolts 33. The top of the mounting bolts 33 is threaded with mounting nuts 34.

[0027] The support frame 31 is in the shape of an "I" and its two ends are movably installed with the upper end of the triangular steel frame 2.

[0028] In this solution, the connection structure greatly improves the overall assembly and disassembly effect. When the guardrail needs to be maintained, parts replaced or rearranged later, the mounting bolts 33 and mounting nuts 34 can be easily removed, achieving quick assembly and disassembly, which is very convenient to use.

[0029] like Figure 4As shown in the figure, the guardrail mechanism 4 includes a fixing plate 41. The lower end of the fixing plate 41 is movably installed on both end parts of the upper end of the support frame 31. A through hole three 42 is penetrated through one side of the fixing plate 41. On the other side of the upper end of the fixing plate 41, a clamping frame 43 is fixedly connected. Three groups of through holes four 44 are penetrated through the surface of the clamping frame 43. Inside the clamping frame 43, a railing frame one 45 and a railing frame two 46 are respectively installed. In the middle parts of the railing frame one 45 and the railing frame two 46, a strengthening rod 47 is fixedly connected. Inside the inner sides of the railing frame one 45 and the railing frame two 46, guardrail plates 48 are fixedly installed.

[0030] Through holes five 49 are penetrated through the bottoms of both the railing frame one 45 and the railing frame two 46. Inside the through holes five 49, fastening bolts 410 are movably inserted. At the bottom ends of the fastening bolts 410, fastening nuts 411 are threadedly sleeved. At the right end part of the railing frame one 45, a clamping rail 412 is fixedly provided. At the left end part of the railing frame two 46, a clamping groove 413 is provided.

[0031] Inside the through holes four 44 and outside the fastening bolts 410 are movably inserted so as to fix the railing frame one 45 and the railing frame inside the clamping frame 43. The clamping frame 43 is in a "C" shape. The lower ends of the railing frame one 45 and the railing frame two 46 match the inner sides of the clamping frame 43 and are movably installed.

[0032] The strengthening rod 47 can enhance the stability of the railing frame one 45 and the railing frame two 46, so as to improve the protection effect of the guardrail plate 48.

[0033] The clamping rail 412 and the clamping groove 413 are fitted and slidably installed so as to splice the railing frame one 45 and the railing frame two 46.

[0034] In this solution, through the three groups of clamping frames 43, like stable bases, stable support is provided for the railing frames, ensuring that they remain stable during placement and are not prone to shaking or displacement.

[0035] In this solution, through the guardrail structure, its installation and connection process is simple and easy to understand. Even ordinary construction workers can quickly get started and operate. And after the construction is completed, the disassembly is also very convenient, enabling quick removal and recycling, bringing great convenience to the construction project, making it reusable and improving the construction efficiency.

[0036] Next, the working principle of the guardrail for the cap beam operation platform will be specifically described.

[0037] As Figures 1-4As shown, when using the guardrail of the operating platform for the cap beam, the support frame 31 is precisely placed in the corresponding pre-designed fitting groove 5, so that the support frame 31 fits against the triangular steel frame 2 on both sides. The support frame 31 has through holes 32 on both sides. When the support frame 31 is accurately placed into the fitting groove 5, the through holes 32 on both sides can be aligned with the through holes 6 on the triangular steel frame 2. Next, the fixing plate 41 is placed on both sides of the upper end of the support frame 31. The fixing plate 41 has through holes 42. When placing it, the through holes 42 are aligned with the already aligned through holes 32. Then, the mounting bolts 33 are passed through these three sets of aligned through holes. After the mounting bolts 33 are passed through, the mounting nuts 34 are used to fit them. Then, the mounting nuts 34 are tightened using a tool. With proper operation, the support frame 31 and the fixing plate 41 are tightly connected, improving overall stability. Then, using the guide rail 412 and slot 413, the first guardrail 45 and the second guardrail 46 are spliced ​​together to form a single unit. The spliced ​​guardrail is then placed in the corresponding bracket 43, aligning the through holes 44 and 49. The fastening bolts 410 are then passed through the through holes 44 and 32, and the fastening nuts 411 are fitted onto the bolts and tightened. This completes the installation of the guardrail, allowing the guardrail plate 48 to fully perform its protective function during subsequent construction, providing comprehensive protection for both sides of the cap beam 1, improving safety and reliability, and ensuring the safety of construction workers working on the cap beam 1.

[0038] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
