[0002] When conducting civil engineering construction, construction frames are used when working on walls or at heights. There are many types of construction frames. For frame-type construction frames, workers are framed in the frame, and another worker pushes the entire construction frame to move by locking and unlocking universal wheels at the bottom. However, even after the construction frame is locked and there are people supporting it at the bottom, this type of construction frame will still shake and be unstable, posing a safety hazard. Therefore, we propose a safe construction frame for civil engineering. Utility Model Content

[0021] Example 1

[0022] like Figure 1-3 As shown, the utility model provides a technical solution: a safe construction frame for civil engineering, including a construction frame 1, in which staggered and connected upward step ladders 11 are arranged, the number of sections of the step ladders 11 is designed according to demand, and universal wheels 12 are installed at the bottom corners of the construction frame 1, and the universal wheels 12 are designed as a lockable structure, and a working platform 2 is arranged between the step ladders 11, and the working platform 2 is installed on the construction frame 1, and an extension platform 3 is hingedly connected to the working platform 2, and the extension platform 3 increases the area of ​​the working platform 2, and the lower part of the extension platform 3 is supported by a support member 4 extending from the working platform 2, thereby supporting the opening of the extension platform 3, and a connecting frame 5 is arranged at the bottom of the construction frame 1 near the short sides on both sides, and an extension frame 6 is slidably connected to the connecting frame 5 at both ends, and a height adjustment component is provided on the part of the extension frame 6 extending from the connecting frame 5, thereby adjusting the contact with the ground to keep the construction frame safe and stable.

[0023] Example 2

[0024] like Figure 1-3 As shown, the construction structure 1 is divided into multiple sections, and each section is connected by bolts and fixings, so that the height of the structure can be increased or decreased according to usage requirements.

[0025] The staff rotates the extension platform 3 and puts it upside down on the working platform 2 when not in use. The extension platform 3 is an L-shaped structure, so as to place tools to avoid falling and prevent the staff from slipping and stepping on empty space.

[0026] The support member 4 is located inside the working platform 2, and a number of them are equidistantly arranged laterally and are slidably connected to the working platform 2, so that the support member 4 can be stored / pulled out. An auxiliary fastener 41 is also installed on the outer end surface of the support member 4. The staff pulls the auxiliary fastener 41 to slide and pull out the support member 4 for storage. When using the extension platform, after pulling the support member 4 to the bottom of the extension platform 3, the extension platform 3 is unfolded to support it, thereby increasing the working space and ensuring its stability.

[0027] The sliding surfaces of the connecting frame 5 and the extending frame 6 are also provided with damping sheets 7 to increase the sliding resistance between the two, thereby preventing the connecting frame 5 and the extending frame 6 from being displaced when they are not pushed.

[0028] The height adjustment assembly includes a threaded lifting rod 8, which is threadedly connected to and passes through the upper and lower ends of the connecting frame 5. A rotating handle 81 is installed on the threaded lifting rod 8 on the upper surface of the connecting frame 5, and a support plate 82 is installed on the threaded lifting rod 8 on the lower surface of the connecting frame 5. The threaded lifting rod 8 adjusts the support plate 82 up and down by twisting the rotating handle 81 forwards and backwards, and then contacts the ground to provide a supporting effect.

[0029] Workflow: When using a civil engineering safety construction frame, the auxiliary personnel push the overall construction frame 1 to move. When it is rotated to the appropriate use direction and position, the universal wheel 12 is locked. The extension frame at the bottom can slide out from the connecting frame 5 according to the construction environment and needs, and the support plate 82 is made to contact the ground by adjusting the rotating handle. The staff pulls the auxiliary fastener 41 to slide and withdraw the support member 4 for storage. When using the extension platform, after pulling the support member 4 to the bottom of the working platform 3, it is supported by unfolding the extension platform 3, thereby increasing the working space. After the construction is completed, the universal wheel 12 is unlocked, and the support plate 82 is adjusted to rise, pushed, and adjusted in position, and this reciprocating process is performed to complete the safe construction of the construction frame.
