[0002] With the accelerating pace of urbanization, all kinds of buildings are springing up like mushrooms after rain. From towering skyscrapers to cozy residential communities, the scale and complexity of construction projects are increasing daily. In this wave of construction, construction safety has become a crucial aspect that cannot be ignored. Construction site safety scaffolds, as indispensable safety facilities on construction sites, are becoming increasingly important. They are widely used in various stages of building construction, including main structure construction, exterior wall decoration, and equipment installation, providing construction workers with a relatively safe working space and effectively preventing falls and falling object accidents. They play an irreplaceable role in protecting the lives of construction workers and ensuring the smooth progress of projects, making them a vital link in the construction safety system.

[0003] However, the current construction site safety scaffolding has revealed some obvious drawbacks in actual use. For example, the safety netting on the surface of the scaffolding cannot be removed and tidied up in sync with the overall operation of the scaffolding and must be done separately. The same applies to the installation, which undoubtedly increases the complexity of the operation process. Moreover, after the safety netting is installed, additional targeted binding operations are required at the turning points of the building structure. These factors combined make the dismantling and installation of construction site safety scaffolding not only troublesome but also extremely labor-intensive, consuming a lot of manpower, material resources, and time, which to some extent affects construction efficiency and project progress.

[0004] Therefore, this utility model provides a construction site protective frame for building engineering to solve the above problems. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5A construction site protective frame includes a protective structure 1, which includes a left frame 11. The right ends of the upper and lower crossbeams of the left frame 11 are fitted with pivots, and double-ear plates integrally formed on the left ends of the upper and lower crossbeams of the right frame 12 are rotatably connected to the right frame 12. Connecting side frames 13 are bolted to the left side of the left frame 11 and the right side of the right frame 12. The upper and lower ends of the connecting side frames 13 are integrally formed with mounting plates for connecting with other protective frames using bolts. The left frame 11 and the right frame 12 rotate between pivots. A dumbbell bag case 14 is connected, which has a dumbbell-shaped box structure. The interior has two cylindrical chambers on the left and right sides for winding. A reel 142 is rotatably mounted at the center of each chamber. The upper and lower ends of the reel 142 are inserted into slots in the top and bottom of the two chambers of the dumbbell bag case 14, and also between a torsion spring 143 fixed to the wall of one end of the slot. One end of the torsion spring 143 is fixed to the reel 142. A safety net is wound around the surface of the reel 142. 141, and the movable side of the safety net 141 extends through the exits on the left and right sides of the corresponding compartment on the surface of the dumbbell box 14, and a positioning end plate 144 is fixedly installed on the movable side. The surface of the positioning end plate 144 has a slot 145 for positioning the safety net 141 on the side with the center near the connecting frame 13. When the safety net 141 is pulled out, the positioning end plate 144 is pushed into the positioning slots on the left side wall of the left frame 11 and the right side wall of the right frame 12, and slides in place. The positioning blade plate 111 inside the left frame 11 will be inserted into the slot 145 to position the safety net 141. The positioning blade plate 111 is slidably inserted into the groove inside the left frame 11, which is connected to the positioning groove on the left side wall of the left frame 11 and the right side wall of the right frame 12. The side of the positioning blade plate 111 facing the slot 145 is set in an arc shape, and the front side of the positioning blade plate 111 is equipped with two limiting springs 112 to connect with and slide with the left frame 11 and the right frame 12.

[0024] During operation, the protective frames are first connected by mounting plates and bolts to form a protective system. When the safety net 141 is unfolded, the positioning end plate 144 is pulled, and the safety net 141 is pulled out from the dumbbell belt box 14. The reel 142 rotates against the elastic force of the torsion spring 143. After the positioning end plate 144 is inserted into the positioning slots of the left frame 11 and the right frame 12, the positioning blade insert plate 111 enters the slot 145 under the action of the limiting spring 112, and the safety net 141 is fixed to achieve protection. When retracting, the positioning blade insert plate 111 is pushed to stretch the limiting spring 112 so that it is disengaged from the slot 145. The elastic force of the torsion spring 143 causes the reel 142 to reverse and roll the safety net 141 back into the dumbbell belt box 14.

[0025] In summary, by placing the safety net 141 inside the dumbbell-shaped box 14 and utilizing the roller 142 and torsion spring 143 in conjunction with the positioning end plate 144, positioning blade insert plate 111, and limiting spring 112, the installation and removal of the safety net 141 can be carried out simultaneously with the overall operation of the protective frame. Unlike traditional protective frames, there is no need to separately remove and organize the safety net 141, simplifying the operation process, reducing operation steps, thereby reducing manpower, material resources, and time costs, and effectively improving construction efficiency and project progress. In addition, with the rotational capabilities of the left frame 11 and the right frame 12 and the function of the dumbbell-shaped box 14, at the turning points of the building structure, there is no need for additional targeted binding operations on the safety net 141. The safety net 141 can be quickly and securely fixed, ensuring that the safety net 141 can effectively play a protective role in various positions, thus improving the convenience and safety of the protective frame.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] Working principle: During operation, the protective frame is first connected to other protective frames via mounting plates and bolts at the upper and lower ends of the connecting side frame 13 to form a protective system. When the safety net 141 needs to be deployed, the positioning end plate 144 is pulled to both sides, causing the safety net 141 to be pulled out of the dumbbell belt box 14. During the process of pulling out the safety net 141, the roller 142 rotates against the elastic force of the torsion spring 143. When the positioning end plate 144 is pushed into the positioning grooves opened on the left side wall of the left frame 11 and the right side wall of the right frame 12, the positioning blade insert plate 111, under the action of the limiting spring 112, has its arc-shaped side surface touching the positioning end plate 144. The insertion side arc surfaces cooperate with each other to push the positioning blade insert plate 111 outward until it is smoothly inserted into the slot 145, positioning the safety net 141, so that the safety net 141 unfolds and is fixed on the protective frame to play a protective role; when it is necessary to retract the safety net 141, push the positioning blade insert plate 111 away from the slot 145, stretch the limiting spring 112, so that the positioning blade insert plate 111 disengages from the slot 145. At this time, under the elastic force of the torsion spring 143, the reel 142 reverses and retracts the safety net 141 into the dumbbell belt box 14, completing the storage of the safety net 141.
