SUMMERY OF THE UTILITY MODEL

Aiming at the problems in the prior art, the utility model provides a flue gas duct with a fixed structure, when the flue gas duct is installed and constructed, a fixing part is pre-buried in advance, and the flue gas duct is directly assembled at the later stage, so that the secondary hole drilling at a structural beam, a wall or a concrete cutting platform when the flue gas duct is installed is avoided, the brought process is complicated, and the leakage problem is easy to generate;

for realizing the purpose of the utility model, the utility model adopts the following technical scheme:

a flue gas duct with a fixed structure comprises; the flue gas channel, the angle steel A, the angle steel B and the reinforcing steel bars; the four surfaces outside the flue gas channel are horizontally provided with bulges, the bulges on the four surfaces are positioned on the same horizontal plane, and the bulges and the flue gas channel body are of an integral structure; four angle steels B are arranged below the bulges; each angle steel B is attached to the bottom of the bulge on the side face of one flue; each angle steel B is buckled with one angle steel A; a plurality of steel bars are welded on one side surface of each angle steel A; the angle steel A and the angle steel B are provided with fixing holes; and each angle steel A and each angle steel B are fixedly connected with the protrusions on the four surfaces of the flue gas channel through the fixing holes by self-tapping screws.

Preferably, the bottom of the bulge is provided with a screw hole, and each angle steel A and each angle steel B are fixedly connected with the bulge on the four surfaces of the flue gas channel through the fixing holes by bolts.

Preferably, the top surface of the angle steel B is provided with an antirust layer.

Preferably, a filling layer is arranged between the outer side surfaces of the four angle steels B and the side wall of the flue gas channel;

preferably, the filling layer is made of flexible fireproof materials.

Compared with the prior art, the utility model, following beneficial effect has:

this flue gas duct is when the installation construction, accomplish accurate location when the major structure construction, once pre-buried, reduce the risk of destroying major structure component, when later stage flue gas duct installs, only need stick up the flue gas duct and target in place the back, assemble fixedly, the root of flue gas duct need not the secondary and hangs the mould, can adopt the pea gravel concreten to irritate the seam fixed, because the angle steel is in the floor bottom, do not influence the construction space requirement of cementation of fissures, when can once only doing the waterproof process construction of back track during the cementation of fissures, adopt flexible fire-proof material to fill, realize flue gas duct and fixed knot structure's flexible contact, the deformation that produces because temperature variation when the release flue gas duct that can be better discharges fume, can further avoid flue gas duct because damage appears after the expend with heat and contract with cold, reduce later stage decorative finish and drop and crack risk.

Detailed Description

The drawings in the embodiments of the present invention will be combined; to the technical scheme in the embodiment of the utility model, clearly, describe completely:

as shown in fig. 1-3, in one embodiment of the present invention, a flue gas duct with a fixed structure comprises; the flue gas channel 1, an angle steel A4, an angle steel B5 and a steel bar 7; the four outer sides of the flue gas channel 1 are horizontally provided with the bulges 2, the bulges 2 on the four sides are positioned on the same horizontal plane, and the bulges 2 and the flue gas channel 1 body are of an integral structure; four pieces of angle steel B5 are arranged below the bulge 2; each angle steel B5 is attached to the bottom of the bulge 2 on the side surface of one flue gas channel 1; each angle B5 is buckled with an angle A4; a plurality of steel bars 7 are welded on one side surface of each angle steel A4; fixing holes are formed in the angle steel A4 and the angle steel B5; and each angle steel A4 and each angle steel B5 are connected and fixed with the protrusions 2 on the four surfaces of the flue gas channel 1 through fixing holes by self-tapping screws.

During the concrete construction, flue installing port department on the floor is pre-buried to reinforcing bar 7 and a side of angle steel A4, four angle steel A4 stretch out from flue installing port below on the floor, an angle steel B5 of hasp on every angle steel A4, put into installing port department with flue 1, contact with angle steel B5 through protruding 2 bottoms, hold flue 1, then adopt self tapping screw connection fixed, the seam department of angle steel B5 top floor and flue 1 pours into pea gravel concreten 11 and seals.
