[0002] Construction engineering refers to the process of building various buildings and engineering structures according to certain designs and plans using human knowledge, technology and resources. These buildings and structures can include residential buildings, commercial buildings, industrial plants, bridges, tunnels, water conservancy projects, etc. When workers work at heights, they can use scaffolding to provide safe support and working platforms, reducing the risk of falling accidents caused by working at heights. Workers can stand and move steadily on the scaffolding to carry out construction, maintenance and decoration work, which greatly improves the safety of work.

[0003] Traditional scaffolding is mainly composed of steel pipes, steel bars, wood or other solid materials to ensure that it has sufficient strength and durability. The joints between steel pipes and steel bars are usually reinforced with welding technology to ensure that the entire scaffolding can remain stable when bearing the workload.

[0004] Although traditional scaffolding improves the stability of the equipment by welding, it does not take into account that the welding method will cause the equipment to be integrated and large in size, which makes it very troublesome to transport, time-consuming, labor-intensive and difficult to carry.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a modular scaffold for construction engineering, including a side frame 1, a hinged frame 2 is fixedly connected to the side wall of the side frame 1, a rotating shaft 3 is rotatably connected inside the hinged frame 2, a fixed sleeve 4 is fixedly connected between the rotating shafts 3, a fixed rod 5 is arranged between the side frames 1, both ends of the fixed rod 5 are rotatably connected to connecting bolts 6, the side wall of the connecting bolt 6 is threadedly connected to the inside of the fixing sleeve 4, a card slot is opened on the side wall of the side frame 1, a pedal 7 is arranged between the side frames 1, a hook 8 is fixedly connected to the side wall of the pedal 7, and the side wall of the hook 8 is slidably connected to the inside of the card slot, a reinforcement component is arranged between the side frames 1, the reinforcement component includes a connecting rod 9 and a nut 10, the side wall of the connecting rod 9 is slidably connected to the inside of the side frame 1, and the inner side wall of the nut 10 is threadedly connected to the two ends of the connecting rod 9.

[0024] When assembling the equipment, first stand the side frames 1 upright on both sides. Next, rotate the connecting bolt 6 connected to one end of the fixing rod 5 and twist it into the fixing sleeve 4 on the side wall of one side frame 1, so as to achieve the preliminary connection between the side frame 1 and the fixing rod 5, and then twist the connecting bolt 6 connected to the other end of the fixing rod 5 into the fixing sleeve 4 on the side wall of the side frame 1 on the other side, so as to perform the preliminary connection and fixation of the side frames 1 on both sides. After the preliminary connection and fixation is completed, pass the connecting rod 9 through the inside of the side frame 1 and place the two ends outside. The purpose of this step is to increase the connection stability between the side frames 1 and make the equipment more stable. Subsequently, twist the nut 10 on both sides of the connecting rod 9 and make it fit tightly with the side frame 1, so as to achieve the re-fixation of the side frames 1 on both sides. Finally, slide the hook 8 connected to the pedal 7 into the card slot opened in the side frame 1 and engage with it, so as to achieve the fixation of the pedal 7 and complete the installation of the equipment.

[0025] Reference Figure 3A fixing frame 11 is fixedly connected to the upper surface of the pedal 7, a connecting plate 12 is rotatably connected inside the fixing frame 11, a rotating block 13 is rotatably connected to one side of the connecting plate 12, a handrail 14 is fixedly connected to the upper surface of the rotating block 13, a limiting block 15 is fixedly connected to the side wall of the right connecting plate 12, a fixing frame 16 is fixedly connected to the lower surface of the handrail 14, a pressing block 17 is slidably connected inside the fixing frame 16, a limiting rod 19 is fixedly connected to the lower surface of the pressing block 17, and the side wall of the limiting rod 19 is slidably connected to the inside of the limiting block 15, a spring 18 is arranged inside the fixing frame 16, one end of the spring 18 is fixedly connected to the inside of the fixing frame 16, and the other end of the spring 18 is fixedly connected to the side wall of the pressing block 17.

[0026] When the staff stands on the surface of the pedal 7 to work, they can pull the handrail 14 to make one side of the connecting plate 12 rotate inside the fixing frame 11. At the same time, the other side of the connecting plate 12 will rotate inside the rotating block 13. This process causes the connecting plate 12 to gradually change from a horizontal state to a vertical state. During the movement of the connecting plate 12, the limit rod 19 will slide along the surface of the limit block 15. During this process, the limit rod 19 will squeeze the spring 18, causing the spring 18 to deform and squeeze the pressure block 17 into the fixing frame 16. When the limit rod 19 moves to above the concave hole opened in the limit block 15, the spring 18 loses its squeezing force and begins to reset. During the resetting of the spring 18, the limit rod 19 is inserted into the limit block 15, thereby fixing the connecting plate 12, making it stably supported on the surface of the pedal 7, protecting the staff and preventing them from falling.

[0027] Working principle: When assembling the equipment for work, first erect the side frames 1 on both sides, and twist the connecting bolt 6 connected to one end of the fixing rod 5 into the fixing sleeve 4 on the side wall of one side frame 1, and then twist the connecting bolt 6 connected to the other end of the fixing rod 5 into the fixing sleeve 4 on the side wall of the other side frame 1, and preliminarily connect and fix the side frames 1 on both sides, and then pass the connecting rod 9 through the inside of the side frame 1, and place both ends outside, and then twist the nuts 10 on both sides of the connecting rod 9 and make them fit with the side frames 1, so as to fix the side frames 1 on both sides again, and finally slide the hook 8 connected to the pedal 7 into the card slot opened in the side frame 1 and engage with it, so as to fix the pedal 7, thereby completing the installation of the equipment. When the worker stands on the surface of the pedal 7 to work, he can pull the handrail 14 to drive one side of the connecting plate 12 to rotate inside the fixed frame 11. At this time, the other side of the connecting plate 12 will rotate inside the rotating block 13, gradually making the connecting plate 12 in a vertical state. When the connecting plate 12 moves, the limit rod 19 will slide on the surface of the limit block 15 and squeeze the spring 18 to make the pressing block 17 slide into the fixed frame 16. When the limit rod 19 moves to above the concave hole opened inside the limit block 15, the spring 18 will lose pressure and reset, thereby inserting the limit rod 19 into the limit block 15, fixing the connecting plate 12, supporting it on the surface of the pedal 7, protecting the worker and preventing him from falling.
