Stiffener cage for use in opening of anchor block for direct-buried heat supply pipelines

Abstract

The invention relates to a stiffener cage for use in an opening of an anchor block for direct-buried heat supply pipelines. The anchor block is a reinforced concrete integrated connector made by subjecting two fixing segments arranged in parallel, a reinforcement fabric and opening stiffeners connected with the reinforcement fabric, to concreting on a base plate. Each fixing segment is a connecting pipe; the outside of the connecting pipe is provided with a circular flange; two ends of each connecting pipe horizontally penetrate one opening of the anchor block; the reinforcement fabric is arranged inside close to the outer surface of the anchor block by lining. The stiffener cage is characterized by comprising a plurality of circular bars and a plurality of longitudinal bars; the circular bars surround the fixing segments in the anchor block and evenly and parallelly arranged axially along the connecting pipes; the longitudinal bars surround the circular bars and are fixedly connected to the circular bars axially along the connecting pipes; the stiffener cage is fixed outside the fixing segments in such a manner that two ends of every longitudinal bar are fixedly connected to the reinforcement fabrics arranged on the front and rear sides of the openings. The stiffener cage has the advantages that overall strength of the anchor block is improved, and the anchor block is protected from damage.

Description

technical field [0001] The invention relates to a reinforcing rib for the opening of a fixed pier of a directly buried heating pipeline, in particular to a cage-type reinforcing rib for the opening of a fixed pier of a directly buried heating pipeline. Background technique [0002] During the laying of direct buried heating pipelines, in order to maintain a firm structure, stable positioning, and no deformation, fixed piers must be set at a certain distance. Such as Figure 1-Figure 2 As shown, the fixed pier is a reinforced concrete integral connector formed by pouring concrete 1 on the base plate 5 by two fixed joints 3 arranged in parallel, a steel mesh 2 and the reinforcing bars of the opening connected to the steel mesh. 3 is the connecting pipe 31 with the annular flange 32 and two ends stretching out across the opening of the fixed pier front and rear sides on the outside, and the connecting pipe 31 is welded and connected with the heating pipeline laid at its two end...

AI Technical Summary

Problems solved by technology

The reinforcing bar structure of the steel mesh has little effect on preventing the punching force generated by the fixed joint of the pipeline, and the effect of preventing the plane cracking of the fixed pier is not obvious, and cannot effectively prevent the damage accident of the fixed pier
