The steel beam 400 can be an I-beam. A safety net 200 is installed between the two beams to prevent workers from falling while working at height. The garbage collector 300 collects waste generated by workers during construction to prevent debris from falling and injuring others. The garbage collector 300 is cleaned regularly without removing the safety net 200, and construction materials dropped by workers can be cleaned to prevent them from being injured by construction materials when they fall from the safety net 200. The split design of the first fixing member 110 and the second fixing member 120 facilitates installation, and the two can be detachably connected. Even if the connection point between one and the steel beam 400 becomes loose, the tension exerted by the other on it prevents it from falling off the steel beam 400, thereby better securing the safety net 200.

[0036] Specifically, the main structure of the first fixing member 110 and the second fixing member 120 is the same, both of which are three plates forming a C-shaped fixing structure, and then fixed to the steel beam 400 by tightening screws. The difference is that the first connecting plate 116 and the second connecting plate 126 have different structures, and the thickness of the first connecting block 115 and the second connecting block 125 can be different, so that the first connecting plate 116 and the second connecting plate 126 are staggered up and down, and the first screw 118 passes through the connecting through hole 1261 and then installs the first locking nut 119. At this time, it does not need to be tightened to prevent the first screw 118 and the second connecting plate 126 from detaching. That is, the first fixing member 110 and the second fixing member 120 are installed on both sides of the steel beam 400 so that the connection point of the steel beam 400 extends between the first upper plate 111 and the first lower plate 113, preferably against the first vertical plate 112. The second fixing member 120 is fixed accordingly. During the adjustment process, the first slide 117 slides in the first slide groove 1161. After adjusting the relative position of the second vertical plate 122 and the first vertical plate 112, the first locking nut 119 is tightened, and then the first clamping screw 114 and the second clamping screw 124 are fixed, thus completing the connection between the first fixing member 110 and the second fixing member 120 and the steel beam 400. Preferably, the number of the connecting through holes 1261 is multiple and they are arranged sequentially along the length direction of the second connecting plate 126, so that the adjustment range is larger.

Multiple mounting mechanisms 100 are arranged along the length of the steel beam 400, with spacing generally less than 600 mm to ensure the stability of the safety net 200. The first chute 1161 is located within the first connecting plate 116. The first connecting plate 116 wraps around the first slide 117, providing a good tightening effect. The top surface of the first connecting plate 116 can also be recessed downward to form the first chute 1161, allowing the position of the first slide 117 to be clearly visible and facilitating its movement. The above structure is generally made of steel and connected by welding.

The third compression screw 1311 is used to compress the second slide 139. The top surface of the first compression plate 134 is provided with a plurality of grooves, and the bottom surface of the second compression plate 1310 is provided with protrusions corresponding to the grooves. A limit member 1313 is provided on the bottom surface of the third upper plate 131, and the second compression plate 1310 is provided with a limit connector 1314 that cooperates with the limit member 1313. The first and second pressure plates 134 and 1310 exert a dual pressure on the safety net 200, enhancing its securement and preventing it from falling. The protrusions of the second pressure plate 1310 pass through the holes in the safety net 200 and then enter the grooves of the first pressure plate 134. In addition to using friction to secure the safety net 200, the second pressure plate 1310 also increases the pulling force of the protrusions, further securing the safety net 200. The stopper 1313 is used to pull up the second pressure plate 1310, preventing it from naturally falling and affecting the installation of the safety net 200 and the first pressure plate 134. After installing the first pressure plate 134 or releasing the stopper 1313 from securing the second pressure plate 1310, the stopper 1313 can be made of a material such as a tensile strength material or a spring, with a hook fixed to its bottom end. The stopper connector 1314 is a snap ring that cooperates with the hook. In this embodiment, the top surface of the third upper plate 131 is provided with a fixing mechanism 1312 for fixing the garbage collecting member 300, which can be fixed by screws or snaps, or an elastic device such as Figure 5In the embodiment, an elastic pressure plate is used. The bottom end of the fixing portion is fixed to the top surface of the third upper plate 131, and the top end is connected to the extrusion portion. The extrusion portion presses downward and abuts the top surface of the third upper plate 131. The extrusion portion is pulled up, and the waste collector 300 is placed in. The waste collector 300 is then fixed by releasing the extrusion portion. The end of the extrusion portion that fixes the waste collector 300 is provided with a non-slip surface or a protrusion, and the top surface of the third upper plate 131 is correspondingly provided with a groove. It should be further explained that the use of other components to achieve the above-mentioned effects should fall within the inventive concept of the present invention and should fall within the scope of protection of the present invention.
