Description

A pre-embedded device for cantilevered scaffolding

technical field

The utility model relates to a suspension scaffold of a high-rise building, in particular to a pre-embedded device of the suspension scaffold.

Background technique

At present, most of the modern buildings are high-rise buildings. When installing the embedded parts of conventional cantilevered scaffolding, the embedded parts are directly embedded in the concrete components. When removing the embedded parts of cantilevered scaffolding, gas cutting or hand-held cutting is often used. Machine cutting, this construction technology wastes materials, and has low construction efficiency, high material costs, and high labor and mechanical equipment input costs.

Utility model content

detailed description

A pre-embedded device for a cantilevered scaffold, as shown in Figure 1-2, the cantilevered scaffold includes an I-beam 1, and the pre-embedded device includes a cover plate 2 and a U-shaped pre-embedded structure set in a concrete member 3 with the opening facing upwards. The U-shaped embedded part includes a bottom bar 4-1 and two straight bars 4-2 vertically arranged at both ends of the bottom bar 4-1, and the connection angle between the bottom bar 4-1 and the straight bar 4-2 Reinforcing ribs 7 are also provided at the place, and the reinforcing ribs 7 are perpendicular to the U-shaped embedded parts. The tops of the two straight rods 4-2 are threadedly connected with connecting rods 6 through connecting nuts 5-1, and connecting nuts 5-1 The bottom end of the straight rod 4-2 is connected by welding, the outer surface of the bottom of the connecting rod 6 is processed into a thread suitable for the connecting nut 5-1, and the I-beam 1 is arranged between the two connecting rods 6 , there is also a wooden wedge 8 between the I-beam 1 and the connecting rod 6, and a through hole corresponding to the position of the two connecting rods 6 is opened on the cover plate 2, and the cover plate 2 passes through the connecting rod 6 and is located on the I-shaped On the beam 1, the outer surface of the upper part of the connecting rod 6 is processed with external threads, and the cover plate 2 presses the upper end of the I-shaped beam 1 through the fastening nut 5-2 set on the connecting rod 6. The both sides of solid nut 5-2 and connecting rod 6 are horizontally engraved with a glyph positioning line respectively.

When in use, the U-shaped embedded part (which can be made of steel bars with a diameter of more than 16mm) is pre-embedded in the concrete member 3, and the hole of the connecting nut 5-1 can be blocked with a plug 9 first, and after the concrete strength meets the requirements, Remove the plug 9, connect the U-shaped embedded part with the connecting rod 6, place the I-beam 1 between the connecting rods 6, and tighten the two sides of the I-beam 1 with wooden wedges 8, then install the cover plate 2 and tighten it with Fastening nut 5-2 can be fastened.

When removing, use a wrench to remove the fastening nut 5-2, the cover plate 2, and the connecting rod 6 respectively and keep them for later use. The operation is simple and convenient for construction, which can realize standardized construction, save the cost of cutting out the embedded parts in the later stage, reduce the source of potential safety hazards, thereby reducing production costs, and improving construction efficiency and construction quality.
