[0002] Safety nets used in building construction are equipment used to protect the safety of workers and the surrounding environment at the construction site. Safety nets are usually made of high-strength polypropylene, polyethylene or other synthetic fibers, and have strong tensile strength and weather resistance. Safety nets can be set on the exterior walls of buildings or suspended parts to prevent construction workers or materials from falling from heights, playing an important role in safety protection.

[0003] Before installing the existing building safety net, it is necessary to first build a bracket to support the safety net as a whole, and then fix the safety net on the bracket. Usually, ropes, wire ropes, buckles or special fixing devices are used to connect the safety net and the bracket. During this operation, it takes a lot of time to tie and connect the safety net, involving multiple steps, which requires high professionalism of the construction workers, increases the difficulty and cost of installation, and improper fixing methods cause the safety net to swing too much after being hit, affecting its protective effect, and even causing the safety net to fall off, reducing the safety of the safety net;

[0004] Most of the existing safety nets used in construction are disposable and cannot be reused, resulting in a waste of resources. During the installation process, different sizes of safety nets will be required at different construction sites, which will affect the overall installation process.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The safety net body is stored by providing a storage cylinder. During the use and installation process, the hollow column is first installed through the installation flange. With the cooperation of the coil spring, the safety net body is pulled out of the storage cylinder by pushing the T-shaped block. After adjusting the length of the safety net body according to the position required for protection at the building construction site, with the assistance of the tension spring, the movable cylinder is pulled close to the connecting rod until the movable cylinder is sleeved to the outer wall of the hemisphere.

As the safety net body is stored, the vertical axis drives the reciprocating screw rod to start rotating through the belt pulley group, and the brush can be driven to move up and down with the cooperation of the guide ball and the limit groove, and then before the safety net body is stored in the storage tube, the mesh of the pulled out part of the safety net body is cleaned, and the dust and dirt adhering to the mesh are brushed off to avoid affecting the corrosion of the safety net body. After cleaning, it is stored in the storage tube, which prolongs the service life of the safety net body and facilitates the subsequent repeated use.

[0019] 3. After fixing the positioning column by the flange, corresponding to the safety net laying range required by the building construction site, after laying out one safety net from bottom to top, it is only necessary to connect the hollow bottom column of the other safety net with the lower convex block to complete the stacking of the two adjacent safety nets, insert the hollow cylinder into the middle of the hollow bottom column and the convex block, and push the push rod to make the slider interact inside the hollow cylinder so that the arc-shaped strips on both sides abut against the outer wall of the hollow bottom column, and then rotate the threaded sleeve on the outer wall of the threaded column to make it gradually approach and abut against the other side outer wall of the hollow bottom column, so as to complete the combination and splicing of the two safety nets, which is more convenient for layout and use at the corresponding building construction site.

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

[0037] See also Figures 1 to 11 , is an embodiment provided by the present invention: a safety net for building construction that is easy to quickly position, comprising a positioning column 1, the middle of the positioning column 1 is rotatably connected to an outer frame 2, the middle of the outer frame 2 is provided with a safety net body 3, the middle of the safety net body 3 is fixedly connected with a plurality of elastic strips 4, the middle of the outer frame 2 is provided with an installation and positioning component for conveniently adjusting and installing the safety net body 3, the rear side of the outer frame 2 is provided with a mesh processing component for processing the safety net body 3, and the outer wall ends of the positioning column 1 are provided with adjustment matching components for splicing the safety net body 3, wherein:

[0038] The installation positioning assembly includes a storage tube 51, which is fixedly connected to the inside of the outer frame 2.

A C-shaped groove 54 is opened in the middle of the side of the outer frame 2 away from the positioning column 1, and T-shaped blocks 55 are slidably connected to the inner walls of the upper and lower sides of the C-shaped groove 54. The sides of the T-shaped blocks 55 on both sides are movably connected to the side of the safety net body 3 away from the storage tube 51, and the sides of the T-shaped blocks 55 on both sides are fixedly connected to the side of the positioning column 1. The connecting rods 56 on both sides are fixedly connected to the hemispheres 512 at one end of the connecting rods 56 on both sides away from the T-shaped blocks 55, and double cones 511 are slidably connected to the outer walls of the connecting rods 56 on both sides;

[0039] The elastic strip 4 is made of polyester fiber, which can effectively absorb impact and friction, has good shock absorption effect, and has good UV resistance, can keep the color from fading for a long time, and is durable. The size of the T-shaped block 55 corresponds to the gap width of the C-shaped groove 54, and the diameter of the double cone 511 is the same as that of the hemispherical body 512.

[0040] Better: when not in use and in the storage state, the safety net body 3 is rolled up inside the storage tube 51, and the T-shaped block 55 is pushed to slide on the inner wall of the C-shaped groove 54, so that the safety net body 3 in the storage tube 51 can be pulled out. The safety net body 3 is wound on the outer wall of the vertical axis 52 by the coil spring 53, and the vertical axis 52 can be driven to rotate during the pulling out process. The setting of the outer frame 2 can play a limiting and guiding role for the safety net body 3 when it is pulled out for use and rolled up for storage. The safety net body 3 is connected to the hemisphere 512 through the connecting rod 56, and the flexibly slidable double cone 511 plays an auxiliary role in the subsequent positioning connection of the safety net body 3.

[0041] The installation and positioning assembly also includes two hollow columns 58 and two movable cylinders 510. The inner walls of the movable cylinders 510 on both sides are slidably connected to the outer walls of the hemispherical bodies 512 on both sides. A groove 513 is provided in the middle of the side away from the movable cylinders 510 on both sides. The insides of the grooves 513 on both sides are slidably connected with wedge blocks 514. Compression springs 515 are sleeved on the outer walls of the wedge blocks 514 on both sides. One end of the compression spring 515 is fixedly connected to the movable cylinder 510, and the other end of the compression spring 515 is fixedly connected to the wedge block 514. A tension spring 59 is provided inside the hollow columns 58 on both sides. One end of the tension spring 59 is fixedly connected to the hollow column 58, and the other end of the tension spring 59 is fixedly connected to the movable cylinder 510. The ends of the hollow columns 58 on both sides away from the T-shaped block 55 are fixedly connected with the mounting flange 57.

[0042] The diameter of the movable cylinder 510 is larger than the diameters of the double cone 511 and the hemispherical body 512. The movable cylinder 510 is configured as a hollow umbrella column. The operation track of the wedge block 514 is located on the same straight line as the center lines of the double cone 511 and the hemispherical body 512.

[0043] Better: the hollow columns 58 on both sides are fixedly installed on the corresponding building steel pipes through the mounting flanges 57, and the movable cylinders 510 on both sides are pulled close to the connecting rod 56 with the cooperation of the tension springs 59. The wedge block 514 squeezes the compression spring 515 upward after being squeezed by the hemisphere 512, and after moving upward inside the groove 513, it moves along the arc trajectory of the hemisphere 512 until it falls and adheres to the side of the hemisphere 512, thereby completing the positioning and locking of the safety net body 3. Accordingly, when the safety net body 3 needs to be disassembled, it is only necessary to continue to push the movable cylinder 510 toward the middle of the connecting rod 56, and push the double cone 511 to abut against the middle section of the connecting rod 56, so that the double cone 511 can no longer slide. During this process, the wedge block 514 moves along the slope trajectory of the double cone 511 and can slide out, thereby releasing the connection lock of the safety net body 3.

[0044] The mesh processing component includes two pulleys 61, both of which are rotatably connected to the inner wall of the outer frame 2, and the pulleys 61 on both sides are connected by a connecting belt 62.

A movable sleeve 64 is threadedly connected to the outer wall of the reciprocating screw rod 63, and a guide ball 65 is fixedly connected to the middle part of one side of the movable sleeve 64. A limiting groove 66 is provided in the middle part of one side of the rear side of the outer frame 2 close to the reciprocating screw rod 63, and the outer wall of the guide ball 65 is slidably connected to the inner wall of the limiting groove 66. A brush 67 is fixedly connected to the middle part of the side of the movable sleeve 64 away from the guide ball 65, and the inner side surface of the brush 67 is closely attached to the rear side surface of the safety net body 3;

[0045] Wherein: the diameter of the guide ball 65 is the same as the size of the limiting groove 66;

[0046] Better: as the safety net body 3 is initially pulled out for use and is retracted and stored after use, the coil spring 53 will follow the operation, causing the vertical shaft 52 to rotate, which can then drive the pulley 61 fixedly connected to it to rotate, and this can be driven by the cooperation of the connecting belt 62; the pulley 61 on the other side rotates, causing the reciprocating screw rod 63 to rotate, and with the cooperation of the guide ball 65 and the limit groove 66, the movable sleeve 64 can move up and down on the rear side of the outer frame 2, so that the safety net body 3 can be rolled up after use, and the inner wall of the mesh of the pulled-out use section of the safety net body 3 can be cleaned, and the dirt and impurities adhered to the inner wall can be brushed off, and finally rolled up and stored, so that the safety net body 3 can be maintained after each use, avoiding the corrosion of the adhered dirt on the safety net body 3, and extending the service life of the safety net body 3.

[0047] The adjustment matching assembly includes a hollow bottom column 71, which is fixedly connected to the bottom end of the positioning column 1, and a protrusion 72 is fixedly connected to the top of the hollow bottom column 71, and the protrusion 72 is matched with the hollow bottom column 71 in a card-engaged manner. A hollow cylinder 73 is provided in the middle of the hollow bottom column 71, and a push rod 74 is provided inside the hollow cylinder 73. One end of the push rod 74 located inside the hollow cylinder 73 is fixedly connected to a sliding column 75, and the outer wall of the sliding column 75 is slidably connected to the inner wall of the hollow cylinder 73. A connecting spring 76 is provided inside the hollow cylinder 73. The connecting spring 76 is provided 6 is fixedly connected to the hollow cylinder 73, the other end of the connecting spring 76 is fixedly connected to the sliding column 75, arc holes 77 are opened in the middle of both sides of the hollow cylinder 73, arc bars 78 are rotatably connected to the middle of both sides of the sliding column 75, and the arc bars 78 on both sides are respectively slidably connected to the inner walls of the arc holes 77 on both sides, and the outer wall of the push rod 74 away from the hollow cylinder 73 is fixedly connected to a threaded column 79, and the outer wall of the threaded column 79 is threadedly connected to a threaded sleeve 710, and the end of the push rod 74 away from the hollow cylinder 73 is fixedly connected to a handle 711;

[0048] Wherein: the material of the protrusion 72 is selected to be rubber, and the shape specifications of the arc hole 77 and the arc strip 78 are correspondingly matched;

[0049] Better: clamp the hollow bottom column 71 on the outer wall of the protrusion 72, then insert the hollow tube 73 through the middle of the hollow bottom column 71 and the protrusion 72, and pull the push rod 74 away from the hollow tube 73, rotate and unfold the end of the arc strips 78 on both sides close to the threaded column 79 and abut against the outer wall of the hollow bottom column 71, then rotate the threaded sleeve 710 threadedly connected to the outer wall of the threaded column 79 until it is rotated and moved to abut against the outer wall of the other side of the hollow bottom column 71, so as to realize the assembly and use of two adjacent safety net bodies 3, which is more convenient and efficient.

[0050] The above implementation works as follows:

[0051] The initialization steps are as follows:

[0052] Take out a set of safety net bodies 3, place them vertically, and fix the whole body by the flange at the bottom of the hollow bottom column 71;

[0053] The working steps are as follows:

[0054] like Figure 1 - Figure 4 and Figure 8 - Fig. 9 As shown, first, push the T-shaped block 55 to slide on the inner wall of the C-shaped groove 54, so that the safety net body 3 in the storage tube 51 can be pulled out, and the hollow columns 58 on both sides are fixedly installed on the corresponding building steel pipes through the mounting flanges 57, and the movable tubes 510 on both sides are pulled close to the connecting rod 56 with the cooperation of the tension spring 59. After being squeezed by the hemisphere 512, the wedge block 514 squeezes the compression spring 515 upward, and after moving upward inside the groove 513, it moves along the arc trajectory of the hemisphere 512 until it falls and adheres to the side of the hemisphere 512, so as to complete the positioning and locking of the safety net body 3. Accordingly, when the safety net body 3 needs to be disassembled, it is only necessary to continue to push the movable tube 510 toward the connecting rod The middle part of 56 is pushed to push the double cone 511 against the middle section of the connecting rod 56, so that the double cone 511 can no longer slide. In this process, the wedge block 514 moves along the slope track of the double cone 511 and can slide out, that is, the connection lock of the safety net body 3 is released. The safety net body 3 is wound on the outer wall of the vertical shaft 52 by the coil spring 53. The vertical shaft 52 can be driven to rotate during the pulling out process. The setting of the outer frame 2 can play a limiting and guiding role for the safety net body 3 when it is pulled out for use and rolled up for storage. The safety net body 3 is connected to the hemispherical body 512 through the connecting rod 56, and the double cone 511 that is flexibly slidably arranged plays an auxiliary role in the subsequent positioning connection of the safety net body 3.

[0055] like Figure 2 - Figure 3 and Figure 5 - Figure 7As shown, as the safety net body 3 is initially pulled out for use and retracted and stored after use, the coil spring 53 follows the retraction and release operation, causing the vertical shaft 52 to rotate, which can then drive the pulley 61 fixedly connected thereto to rotate, and with the cooperation of the connecting belt 62, it can be driven; the pulley 61 on the other side rotates, causing the reciprocating screw rod 63 to rotate, and with the cooperation of the guide ball 65 and the limiting groove 66, the movable sleeve 64 can move back and forth up and down on the rear side of the outer frame 2, so that the safety net body 3 can be rolled up after use, and the inner wall of the mesh of the pulled-out use section of the safety net body 3 can be cleaned, and the dirt and impurities adhered to and accumulated on the inner wall can be brushed off, and finally rolled up and stored, so that the safety net body 3 can be maintained after each use, avoiding the corrosion of the adhered dirt on the safety net body 3, and extending the service life of the safety net body 3;

[0056] like Figure 1 - Figure 2 and Fig.10 - Fig.11 As shown, after a set of safety net bodies 3 are installed, corresponding to the construction environment of the building construction site, the hollow bottom column 71 is clamped on the outer wall of the protrusion 72, and then the hollow cylinder 73 is inserted through the middle of the hollow bottom column 71 and the protrusion 72, and the push rod 74 is pulled away from the hollow cylinder 73, and the ends of the arc strips 78 on both sides close to the threaded column 79 are rotated and unfolded and abutted against the outer wall of the hollow bottom column 71, and then the threaded sleeve 710 threadedly connected to the outer wall of the threaded column 79 is rotated until it is rotated and moved to abut against the outer wall of the other side of the hollow bottom column 71, so that the assembly and use of the two adjacent safety net bodies 3 is realized, which is more convenient and efficient;

[0057] Finally, after the construction of the building is completed, each group of safety net bodies 3 are unlocked and stored in turn. Corresponding to the operating process in the above process, before the safety net body 3 is rolled up into the storage tube 51, the dirt on the inner wall of the mesh of the safety net that has been pulled out for use is cleaned to ensure the overall cleanliness of the safety net body 3, which is more guaranteed for the quality of subsequent use, thereby achieving multiple recycling uses that are more environmentally friendly.
