The vertical poles are laterally fixed by arranged longitudinal poles. Two blocks are fixedly installed on the upper surface of the safety platform, and clamps are nested and fixed on the outer surfaces of the two blocks. Two first angle steels are fixedly installed through the bottom of the safety platform. The device forms an annular closed working area on the upper surface of the safety platform by arranging vertical poles and longitudinal poles, and the protective net arranged can prevent falling, can withstand impact force, and prevent people from falling accidentally.

[0035] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a retractable cap beam safety working platform, including a main platform 1, which is divided into two sections, and a movable platform 2 is arranged between the two sections of the main platform 1. The two ends of the movable platform 2 are movably connected to the two sections of the main platform 1 respectively. The main platform 1 is composed of a main frame 3 and a bottom plate 4 movably embedded in the main frame 3. The movable platform 2 is a movable square tube 8 arranged between the two sections of the main platform 1. Two movable square tubes 8 are arranged side by side. The ends of the two movable square tubes 8 are movably connected to the main frame 3 and can be completely embedded in the main frame 3. A bottom plate 4 is also movably embedded between the two movable square tubes 8. A connecting hole 9 is provided on the side of the main frame 3 away from the column 6, and the connecting hole 9 vertically penetrates the main frame 3. Through this structural method, the main frame 3 is horizontally laid on the distribution beam of the cap beam, and the main frame 3 is connected to the distribution beam by passing through the connecting hole 9 on the main frame 3 through the U-shaped clip, and then the bottom plate 4 is embedded in the main frame 3 to build a safety platform on the cap beam. Among them, through the stretching of the two sections of the main frame 3, a pair of movable square tubes 8 can be pulled out or inserted into the main frame 3, so as to adjust the overall length of the main frame 3, which can cope with cap beams of various sizes, and prevent the waste of over-set or under-set of the cap beam platform set due to different sizes, and ensure that the main platform plate 1 can be fully laid around the cap beam.

[0036] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5As shown, support bars 11 for supporting the bottom plate 4 are provided on the opposing sides of the pair of movable square tubes 8 and on the inner wall of the main frame 3. The support bars 11 on the movable square tubes 8 are movably plugged into the main frame 3, and the support bars 11 on the movable square tubes 8 and the support bars 11 on the main frame 3 are staggered up and down, which facilitates the insertion and folding of the movable square tubes 8 and the support bars 11 on the movable square tubes 8 into the main frame 3. The bottom plate 4 includes a first plate frame 17 that can be embedded in the main frame 3 and between the pair of movable square tubes 8. A footboard 18 is fixed in the first plate frame 17, and the upper surface of the footboard 18 is provided with anti-slip ridges.

[0037] like Figures 1 to 3 As shown, one side of the main table 1 and the movable table 2 in the two sections is detachably equipped with a guardrail 5. The guardrail 5 includes a plurality of columns 6 vertically on one side of the main frame 3 and a mesh plate 7 movably inserted between the plurality of columns 6. A sleeve 12 is vertically arranged on the side of the main frame 3. The bottom end of the column 6 is movably inserted into the sleeve 12. A fixing bolt 16 passing through the column 6 is horizontally passed through the sleeve 12 for connecting and fixing the column 6. A connecting flange 15 is connected between the side wall of the sleeve 12 and the upper surface of the main frame 3. The connecting flange 15 is set to a triangular structure, which can improve the stability of the sleeve 12. The facing sides of the two adjacent sleeves 12 are each provided with a second rail 14. The bottom end of the second rail 14 is closed, and a skirting board 10 is movably inserted between a pair of second rails 14 to prevent the foot from getting stuck and the workpiece from falling from a high altitude.

[0038] like Figure 1 and Figure 2 As shown, the two sections of the main platform 1 are hinged on one side away from the guardrail 5 with a first hinged plate 21 that can be flipped upward. By setting the first hinged plate 21, during installation and construction, the first hinged plate 21 is flipped upward to create space for installation and construction. After the construction is completed, the first hinged plate 21 can be restored to ensure that the platform is fully paved and prevent people from falling. A second hinged plate 22 is movably inserted between the pair of first hinged plates 21 for cooperating with the pulling and adjusting of the movable platform 2.

[0040] The working principle of the technical solution provided by the utility model is as follows:

[0041] When in use, the main frame 3 is laid horizontally on the distribution beam of the cap beam, and the main frame 3 is connected to the distribution beam by passing the U-shaped clip through the connection hole 9 on the main frame 3. During the connection process, by stretching the two sections of the main frame 3, a pair of movable square tubes 8 can be pulled out or inserted into the main frame 3, so as to adjust the overall length of the main frame 3, which can cope with cap beams of multiple sizes, prevent the waste of over-set or under-set of the cap beam platform set due to different sizes, and ensure that the main platform plate 1 can be fully laid around the cap beam. Furthermore, a base plate 4 is embedded between the main frame 3 and a pair of movable square tubes 8, and then a sleeve 12 is fixed on the side of the main frame 3 away from the cap beam, and the column 6 is vertically inserted into the sleeve 12. A second plug-in rail 14 is used to plug the skirting board 10 between two adjacent sleeves 12 for skirting protection, and a pair of plug-in rails 13 are used to plug the mesh plate 7 between two adjacent columns 6, thereby forming a guardrail 5 on the side of the main frame 3 away from the cap beam to ensure that protection is in place and the overall safety performance is effective. The overall modular design is convenient for combined installation and disassembly, transportation and storage, and the two-section design of the main platform 1 is coordinated with the telescopic movable platform 2. Under the condition of meeting safety performance, the platform length can be changed at any time according to the characteristics of the on-site cap beam. It has strong adaptability and conforms to the variability of construction, thereby making on-site construction convenient, safe and reliable, and effectively solving the problems caused by different sizes of construction cap beams.
