[0019] like Figs. 1 to 3 As shown, a drill-free adjustable guardrail includes at least two fixing plates 1, an adjusting and fastening unit 6, and a protective crossbar 10. Each fixing plate 1 includes a C-shaped steel plate and an adjusting sleeve 3, which are combined into one unit, one on each side, and used as a set with the protective crossbar 10. The pressing surface of the C-shaped steel plate connected to the wall is provided with a rubber protective pad 2 to prevent wear on the surface of the protective fastener. The adjusting sleeve 3 is provided with at least two threaded fixing holes 4, and locking bolts 5 are connected in the threaded fixing holes 4. The locking bolts 5 are arranged vertically to tighten and fix the position. The protective crossbar 10 is embedded in the adjusting sleeve 3, connects the two fixing plates 1, and is tightened and fixed by the locking bolts 5 to form a rigid structure guardrail. The entire guardrail is secured by the two fixing plates 1 to bear the force and resist deformation, and the protective crossbar 10 and the adjusting sleeve 3 are combined and fastened to bear the horizontal and vertical force components, ensuring the safety and firmness of the guardrail. The locking bolts 5 adjust the size of the protective crossbar 10 and tighten and lock the protective crossbar 10. The C-shaped steel plate of the fixing clamp 1 is welded from steel plates or bent into a frame structure. The component has accurate cross-sectional dimensions and good linear effect, ensuring a tight fit between the fixing clamp 1 and the fixed object. The adjusting sleeve 3 is a common square steel pipe with an inner diameter larger than the outer diameter of the protective crossbar 10 and a length of 20cm. Different lengths of protective crossbars 10 can be selected and embedded into the adjusting sleeve 3 within the sleeve's adjustment range, which helps to improve the versatility of this drill-free adjustable guardrail.
[0020] The adjusting fastening unit 6 comprises an adjusting rod 7, a connecting piece 8, and an adjusting plate 9, which are matched with the fastening fixed clamping plate 1. The adjusting rod 7, the connecting piece 8, and the adjusting plate 9 are rigidly connected by welding to ensure the fastening effect. The C-shaped steel plate is further provided with a threaded hole for connecting the threaded screw rod 7-2. The adjusting rod 7 comprises an operating handle 7-1 and a threaded screw rod 7-2, one end of which is fixedly connected with the operating handle 7-1, and the other end penetrates through the threaded hole and is connected with the adjusting plate 9 through the connecting piece 8. The connecting piece 8 uses a sliding bearing, and the adjusting rotation is smooth and light. By rotating the threaded screw rod 7-2 through the operating handle 7-1, the threaded screw rod 7-2 is driven to advance or retreat through the connecting piece 8 to adjust the stroke, fasten or loosen the fixed clamping plate 1. The adjusting plate 9 is a common steel plate, and the pressing surface is provided with a rubber protective pad 2 to prevent the surface of the fixed part from being abraded.
[0021] In addition, the fixed clamping plate 1, the adjusting fastening unit 6, and the protective cross rod 10 can be modularly processed and installed, which is beneficial to enhancing the operability of the adjustable protection railing without punching holes, and the safety protection of the edge of a high building in each construction engineering can be used.
[0022] The working principle of the adjustable protection railing without punching holes is as follows: first, the fixed clamping plate 1 is arranged on both sides of the edge of the wall body at the edge of the high building, the adjusting rod 7 is operated to rotate, the adjusting plate 9 is driven to advance or retreat through the connecting piece 8 to adjust the stroke, and the fixed clamping plate 1 is fastened or loosened to ensure that the fixed clamping plate 1 is closely combined with the fixed wall body to form a force bearing root point. Finally, the protective cross rod 10 is embedded into the adjusting sleeve 3, and the locking bolt 5 is tightened to fix the position up and down, and then the entire protection railing is locked.
