Detailed Description

In order to fully understand the objects, features and functions of the present invention, the following detailed description of the present invention is given, but the present invention is not limited thereto.

The utility model provides a pair of special layer height sectional type flue concatenation reinforced structure comprises forked tail hoop 3, angle bead backing plate 4, sealing strip 5, the spacing intubate of flue 6 etc.. The end face of the flue is rectangular, square or round. The embodiment will be described with the flue end face being square.

Referring to fig. 1 to 3, the lower port of the upper flue 1 and the upper port of the lower flue 2 are respectively inserted into a flue limiting insertion tube 6, the flue limiting insertion tube 6 is composed of an upper limiting tube 61, a lower limiting tube 63 and a supporting ring 62, inner edges of the upper and lower limiting tubes 63 are flush with an inner edge of the supporting ring 62, and the upper limiting tube 61 and the lower limiting tube 63 are respectively fixed on upper and lower surfaces of the supporting ring 62. The outer edges of the upper limiting pipe 63 and the lower limiting pipe 63 are attached to the inner wall of the flue, and the outer edge of the supporting ring 62 is flush with the outer wall of the flue.

The seam crossing outside suit dovetail 3 of upper and lower flue 2, the concave font structure of dovetail 3, dovetail 3's inner wall are fixed with angle bead backing plate 4, because the flue is the square structure, and angle steel preparation is chooseed for use to angle bead backing plate 4. Preferably, four corner protection base plates 4 are arranged on the dovetail hoops 3, and the four corner protection base plates 4 are respectively attached to four corners of the cube flue; the height of the corner protection base plate 4 is higher than that of the dovetail hoops 3, so that the flue corner is protected.
