DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0031] like Figure 1-Figure 7 As shown, the utility model of the turnaround clamp-type quick-disassembly and assembly guardrail includes: a column 1, a U-shaped fixing card 2, a wire rope 5 and a bolt assembly 4, a plurality of columns 1 are installed at intervals on the same side of the H-shaped steel beam 3; a plurality of U-shaped fixing cards 2 are installed on the other side of the H-shaped steel beam 3, and the U-shaped fixing cards 2 correspond to the columns 1 one by one; the columns 1 and the U-shaped fixing cards 2 are both installed on the H-shaped steel beam 3 by the bolt assembly 4, and the installation and removal are simple and convenient, and only the bolts need to be operated, which not only saves labor but also saves materials and energy; the columns 1 and the U-shaped fixing cards 2 and the columns 1 are connected by the wire rope 5, and the two fixing measures ensure that the safety protection is firm and reliable under the premise of simple operation.

[0032] like Figure 3 As shown, the bolt assembly 4 includes a fixing nut 404 and a detachable enlarged disc bolt matched with the fixing nut 404; the fixing nut 404 is fixed on the column 1 or the U-shaped fixing card 2, and the enlarged disc bolt includes a screw rod 401 and an enlarged disc 402 located at the bottom end of the screw rod 401, the end face of the enlarged disc 402 is a plane, and the enlarged disc 402 can abut against the H-shaped steel beam 3, and a knob 403 with a hole is provided on the end of the screw rod 401 away from the enlarged disc 402.

[0033] The perforated knob 403, the screw rod 401 and the enlarged disc 402 are an integrally formed structure.

[0034] The outer diameter of the holed knob 403 is not greater than the outer diameter of the screw rod 401 , so that the holed knob 403 can smoothly pass through the fixing nut 404 , thereby making the screw rod 401 match the fixing nut 404 .

[0035] The screw rod 401 is customized with a φ10 bolt, and an enlarged disc 402 is arranged at the bottom of the screw rod 401, which is conducive to tightening with the H-shaped steel beam 3. A knob 403 with a hole is arranged on the top of the screw rod 401 for tightening the bolt. The screw rod 401 is installed in conjunction with a fixing nut 404 welded on the fixing plate and the U-shaped fixing card 2. After tightening, the column 1 and the H-shaped steel beam 3 are firmly fixed. When removing the column 1, it is only necessary to remove the enlarged disc bolt.

[0036] Before using the bolt assembly 4, first pass the knob 403 with a hole and the screw 401 through the fixing nut 404, and rotate the screw 401 upward to leave a gap below for easy insertion of the H-shaped steel beam 3. After the H-shaped steel beam 3 is inserted into the column 1 or the U-shaped fixing card 2, rotate the knob 403 with a hole so that the enlarged disc 402 is pressed against the H-shaped steel beam 3.

[0037] like Figure 2 As shown, there are three columns 1, which are steel pipe columns, and the three columns 1 are spaced apart and arranged on the H-shaped steel beam 3. The columns 11 are made of φ48 steel pipes, and the distance between two adjacent columns 1 is 1500mm.

[0038] Three connection disks 101 are arranged at intervals along the axial direction on each column 1. The connection disks 101 are sleeved on the column 1 and are perpendicular to the column 1. The connection disks 101 and the column 1 are fixedly connected by welding. Four connection holes 6 are evenly arranged along the circumference on each connection disk 101. The connection disk 101 is a circular disk with a diameter of 120 mm and a thickness of 6 mm, one at the top, the middle and the bottom. Four connection holes 6 are arranged on each connection disk 101. The connection holes 6 are used to install the steel wire rope 5. The four connection holes 6 can ensure that the steel wire rope 5 can be installed quickly and conveniently in any direction.

[0039] The plurality of columns 1 are connected by three steel wire ropes 5 , and each steel wire rope 5 passes through the connecting holes 6 on the adjacent columns 1 in sequence to be connected to the columns 1 .

[0040] The steel wire rope 5 is a φ6 steel wire rope, which is installed between the columns 1 to play a safety protection role, with one wire rope at the top, middle and bottom. When the steel wire rope 5 is located at the columns 1 at both ends, the two ends of the steel wire rope 5 are fixed with steel wire rope clamps 501. Four steel wire rope clamps 501 are provided. When the steel wire rope 5 is located at the middle column 1, it directly passes through the connecting hole 6. The steel wire rope 5 can also be used to fasten a safety belt.

[0041] like Figure 1 and Figure 5 As shown, two fixing plates are provided at the bottom of each column 1 along the axial direction, namely, a lower fixing plate and an upper fixing plate 102. The fixing plates are located below the connecting plate 101. The lower fixing plate is located at the bottom end of the column 1 and is connected to the H-shaped steel beam 3. The upper fixing plate 102 is located at the lower end of the column 1 and is connected to the H-shaped steel beam 3 through the bolt assembly 4. By rotating the knob 403 with a hole, the enlarged disk 402 of the enlarged disk bolt can be pressed against the H-shaped steel beam 3, and the column 1 and the H-shaped steel beam 3 are fixed firmly. When dismantling, only the enlarged disk bolt needs to be removed.

[0042] like Figure 6 As shown, four bolt holes are evenly arranged along the circumference of the upper fixing plate 102, which can ensure that there are two bolts involved in the fixing force when the column 1 is installed on any vertical surface to ensure firmness. When the column 1 is set at the position of the cross-intersecting steel beams, it can be ensured that there are three bolts involved in the force, which is more stable.

[0043] A fixing nut 404 is disposed above each bolt hole, and the upper fixing plate 102 is connected to the screw rod 401 in the bolt assembly 4 via the fixing nut 404 .

[0044] like Figure 1 and Figure 3 As shown, the U-shaped fixing card 2 includes an upper plate 201, a lower plate 202 and a connecting plate 203. The upper plate 201 and the lower plate 202 are connected by the connecting plate 203. The lower plate 202 is clamped on the H-shaped steel beam 3, and the upper plate 201 is connected to the bolt assembly 4.

[0045] The U-shaped fixing card 2 is made of 6 mm thick steel plate, with a length of 100 mm, a width of 60 mm, and a height of 80 mm.

[0046] like Figure 4 As shown, two bolt holes and one connecting hole 6 are provided in the upper plate 201, and fixing nuts 404 are welded above the two bolt holes. The two fixing nuts 404 are respectively connected to the screw rods 401 in the two bolt assemblies 4, so as to fix the U-shaped fixing card 2 and the H-shaped steel beam 3; the connecting hole 6 is connected to the steel wire rope 5, so as to tighten the column 1 from another direction.

[0047] The U-shaped fixing card 2 is connected to the connecting plate 101 at the upper end of the column 1 by a wire rope 5. Each column 1 is provided with one wire rope for tightening and fixing the column 1 from another direction to ensure firmness. Both ends of the wire rope 5 are fixed with wire rope clamps 501.

[0048] When in use, the H-shaped steel beam 3 is clamped between the upper plate 201 and the lower plate 202 of the U-shaped fixing card 2. By rotating the holed knob 403, the enlarged disc 402 of the enlarged disc bolt can be pressed against the H-shaped steel beam 3, and the U-shaped fixing card 2 and the H-shaped steel beam 3 are firmly fixed. When removing, it is only necessary to rotate the holed knob 403 in the opposite direction to remove the enlarged disc bolt.

[0049] When the utility model is used, the column 1 and the U-shaped fixing card 2 are first fixed to the H-shaped steel beam 3 with the bolt assembly 4, and then the plurality of columns 1, as well as the column 1 and the U-shaped fixing card 2 are reinforced with the steel wire rope 5. When dismantling, it is only necessary to reversely rotate and dismantle the bolt assembly.
