The suspending structure of the internal cylinder chimney is simple in structure, and the internal cylinder can be stressed uniformly; therefore, the reliability of the suspension type internal cylinder chimney is improved and the material for the cylinder wall is saved.

Description

A kind of suspended structure of inner core chimney
Technical field
The utility model relates to a kind of suspended structure, relates in particular to a kind of suspended structure of inner core chimney.
Background technology
The self-supporting steel inner cylinder be a kind of Steel Inner Core of Chimney comparatively common structure is set, promptly steel inner cylinder is directly installed in the chimney, bears the weight of self, inner core is in pressured state under the deadweight effect.Therefore, under external force and deadweight effect, the self-supporting steel inner cylinder is in curved pressure condition, the stable often control of its structure wall thickness.The suspension type steel inner cylinder then is suspended on the chimney top with inner core, and inner core is in tension state under the deadweight effect.Its structural thickness is the control of material tensile strength.Therefore, the barrel thickness of self-supporting steel inner cylinder is greater than the barrel thickness of suspension type steel inner cylinder.Be economical with materials, people use the suspension type Steel Inner Core of Chimney to replace the self-supporting Steel Inner Core of Chimney.
But, one of bottleneck that is designed to the development of this type of restriction chimney of the suspension platform of suspension type Steel Inner Core of Chimney and node.People adopt the steel platform usually and 4 to 8 supporting-points are set on steel inner cylinder and bear whole inner core weight at present.This sus-pension can make inner core produce bigger local moment of flexure, and structure stress is extremely unreasonable.In order to overcome this detrimental effect, need to strengthen wall thickness, make that wall thickness is that the inner core of 8mm needs the part to thicken 20mm.This way has following shortcoming:
(1) because the design defectiveness of Steel Inner Core of Chimney suspended structure, cause stressed unreasonablely, make its structure have inadequate natural endowment, long-time running has potential safety hazard;
(2) owing to need local thickening wall thickness, material usage increases.
Summary of the invention
The purpose of the utility model provides a kind of suspended structure of inner core chimney, and than existing suspended structure, the suspended structure of this inner core chimney can make inner core stressed evenly, and reliability improves, and can practice thrift the barrel material.
According to the foregoing invention purpose, the utility model provides a kind of suspended structure of inner core chimney, said inner core chimney is arranged in the supporting with it urceolus chimney hangingly, and said suspended structure comprises:
The suspension platform of one annular, it is fixedly set on the inwall of said urceolus chimney;
One steel-support ring, it is fixedly set on the said suspension platform, and said steel-support ring is provided with said suspension platform is concentric;
One annular brace beam, it is located at the outer exterior wall of said inner core chimney around ground and is fixedly connected with the outer wall of said inner core chimney, and the lower surface of said annular brace beam is shelved on the upper surface of said steel-support ring.
The outer wall at inner core top is provided with the annular brace beam; It is fixedly connected with inner tank theca; And be shelved on the steel-support ring; Make the gravity of inner core pass to the steel-support ring by the annular brace beam equably, pass to suspension platform and urceolus chimney equably successively by the steel-support ring again, form stressed even, a reliable suspension.
In the suspended structure of above-mentioned inner core chimney, said suspension platform comprises a reinforced concrete circle beam.
In the suspended structure of above-mentioned inner core chimney, said suspension platform comprises two-layer, and its lower floor is a steel construction layer, and the upper strata comprises a reinforced concrete circle beam, constitutes steel+concrete combined platform.
In the suspended structure of above-mentioned inner core chimney, the ring wall axial slices of said steel-support ring is trapezoidal.
The suspended structure of the described inner core chimney of the utility model simple in structure, and can make inner core stressed evenly, thus improved the reliability of suspension type inner core chimney, practiced thrift the barrel material.The suspended structure of the described inner core chimney of the utility model not only is fit to the suspension steel inner cylinder, is more suitable for hanging the fiberglass inner core.
