Hanging device for cantilever casting hanging basket

Abstract

The invention provides a hanging device for a cantilever casting hanging basket. The hanging device consists of a nut 1, spherical washers 2, a double-end lead screw 3, a conversion connector 4, a steel plate hanging belt 5, a pin shaft 6, a nut 7 and a nut 8, wherein the conversion connector 4 consists of a cross beam plate 9, a side hanging plate 10 and a side hanging plate 11; vertically communicated bolt holes are formed in the other ends, opposite to the beam plate 9, of the side hanging plate 10 and the side hanging plate 11; the double-end lead screw 3 is connected to one end of the conversion connector 4 by the nut 7 after penetrating through the beam plate 9, and the steel plate hanging belt 5 is connected to the other end of the conversion connector 4 by the pin shaft 6; and the spherical washers 2 respectively serve as washers of the three nuts. The hanging device is characterized in that the steel plate hanging belt plate is connected through the conversion connector; and screw-thread steel bars are not required, but are replaced by lead screws and the nuts, so that the safe hanging can be realized, the dangerous factors are eliminated, the operation is convenient, quick and simple, and the construction efficiency is improved.

Description

technical field [0001] The invention belongs to the field of design and manufacture of bridge construction equipment, and in particular relates to a hanging device for a cantilever casting hanging basket. Background technique [0002] Reinforced concrete continuous rigid frame bridges are generally constructed by cantilever casting with hanging baskets (triangular hanging baskets and prismatic hanging baskets). The sling of the hanging basket is an important stress-bearing part of the hanging basket. All the weight of the formwork and the poured bridge segment concrete is transmitted to the main truss of the hanging basket through the sling. The sling usually adopts two forms of finished-rolled rebar or steel plate. The finished-rolled rebar is a rebar material for prestressed concrete. It has high strength, but its cold bending performance is poor, and it cannot be bent. Cracks are brittle materials. During the working process and when the basket is moved, bending moments...

AI Technical Summary

Problems solved by technology

The sling usually adopts two forms of finished-rolled rebar or steel plate. The finished-rolled rebar is a rebar material for prestressed concrete. It has high strength, but its cold-bending performance is poor, and it cannot be bent. Cracks are brittle materials. During the working process and when the basket is moved, bending moments are inevitably generated. In the past construction sites, there were often major fractures of the finish-rolled rebar. At the same time, the pitch of the finish-rolled rebar is relatively large. It is difficult and inaccurate to finely adjust the height of the hanging basket; the steel plate sling is made of long steel plates, but it is difficult to adjust the height of the hanging basket, and it takes a long time to adjust the basket. Many holes need to be drilled on the sling and multiple sets of spacers are added. The value of the set elevation can be reached, and the adjustment of the basket is very cumbersome
