[0002] Large steel box girders have the advantages of light weight, large span, short bridge construction period, easy quality assurance and high reliability. In steel structure bridges, box girders account for a high proportion. According to the processing and manufacturing process of steel box girders, the parts of the box girder segments will be cut using special cutting equipment, and then the plate units will be made. In order to ensure the processing quality and reduce the bridge construction period, the overall segment needs to be welded after the plate units are made.

[0003] During the assembly process of steel beam manufacturing, there are a lot of high-altitude operations. In order to ensure stability, traditional edge protection railings usually need to be welded to the beam sections, which may damage the parent material. Summary of the invention

[0042] Reference Figure 1 As shown, the utility model is a non-code assembled prefabricated edge guardrail for high-altitude operation of a steel structure, comprising at least one guardrail unit 100, wherein the guardrail unit 100 comprises:

[0043] A base plate 1 provided with a connecting structure 2;

[0044] A plurality of column sleeves 3 are distributed in a straight line on the surface of the base plate 1;

[0045] A plurality of columns 4 are plugged into the column sleeves 3 in a one-to-one correspondence, and a crossbeam sleeve 5 is provided along the length direction of the side wall of each column 4 (by welding);

[0046] A plurality of cross beams 6 are correspondingly inserted into the cross beam sleeves 5 of the columns 4; and

[0047] Connector 7;

[0048] The connection structures 2 of each of the two adjacent guardrail units 100 can cooperate with the connection piece 7 at the same time, so that the multiple guardrail units 100 are spliced ​​into one, and the beams 6 of corresponding heights in the two adjacent guardrail units 100 are butt-jointed.

[0049] It can be understood that the cross beams 6 of corresponding heights in two adjacent guardrail units 100 are connected to each other, which means that after the guardrail units 100 are connected, the cross beams 6 of the same height of two adjacent guardrail units 100 are connected at the same height (with a gap or abutting each other).

[0050] Specifically, refer to Figure 2 As shown, the base plate 1 is a rectangular structure, the connecting structure 2 includes a connecting ring 21, and the connecting member 7 includes a U-shaped pin. The surfaces at both ends of the base plate 1 in the length direction are respectively provided with the connecting ring 21, and the axis of the connecting ring 21 extends along the width direction of the base plate 1.

[0051] Specifically, two connecting rings 21 are symmetrically arranged on the surfaces of both ends of the base plate 1 in the length direction and along the width direction of the base plate 1 .

[0052] Specifically, the connecting ring 21 includes a nut and can be connected to the base plate 1 by welding.

[0053] In this embodiment, the column sleeve 3 and the column 4 are both hollow square tubes; the beam sleeve 5 and the beam 6 are both hollow circular tubes; the base plate 1 adopts a rectangular plate of 16mm (thickness) × 300mm (width) × 3000mm (length), and two square tubes with specifications of 60mm (length) × 60mm (width) × 2.5mm (wall thickness) and 200mm high are welded on the surface through a 4mm circumferential fillet weld as the column sleeve 3; the column adopts a square tube with a cross-sectional specification of 50mm (length) × 50mm (width) × 3mm (wall thickness) and an overall length of 1200mm; the beam 6 adopts a hollow circular tube with a specification of φ48mm × 2.5mm (wall thickness) and a length of 2980mm; each of the guardrail units 100 includes two of the columns 4 and two of the beams 6; the connecting ring 21 adopts an M20 nut; the specification of the U-shaped pin is φ16mm.

[0054] Specifically, refer to Figure 3 As shown, in order to prevent rust caused by water in rainy days and to improve the aesthetic effect, a sealing plate 41 with a thickness of 4 mm is welded to the top of the column 4.

[0055] Specifically, to prevent the cross beam 6 from colliding during the extension process, a predetermined distance is reserved between the two ends of the cross beam 6 and the edge of the base plate 1 in the length direction. Specifically, the two ends of the cross beam 6 are 10 mm smaller than the edge of the base plate 1 in the length direction. In addition, considering the cost issue comprehensively, all the main materials used are made of Q235B steel.

[0056] After the above-mentioned edge protection railing is assembled, the center of gravity is located 155 mm above the surface of the base plate 1 and close to the ground, which can effectively curb the risk of falling of workers working on the edge.

[0057] The assembled edge guardrail can effectively reduce the labor cost during the assembly process. When the protection requirement is greater than 3m, multiple pieces of guardrails can be connected to extend the length, and U-shaped pins can be used to connect them so that adjacent guardrail units 100 are connected as a whole. At the same time, in order to withstand greater impact without overturning and avoid falling from a high altitude, after the assembled edge guardrail is installed, the free edge of the base plate 1 flush with the steel beam is clamped with a clamp to make the guardrail and the steel beam more firmly combined.

[0058] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
