And a reinforcing mesh is arranged in the L-shaped outer rabbet reverse ridge step.
A construction method of a layered flue of a high-rise building comprises the following steps:
firstly, pouring concrete of the floor slab poured with concrete on the floor, and forming a reserved opening of the flue on the floor;
secondly, erecting a hoisting template at the reserved opening of the flue and arranging a reinforcing mesh inside the template, when the concrete of the floor slab poured by the concrete is initially set, pouring fine stone concrete in the hoisting template after the reserved opening of the flue is erected to form an L-shaped outer rabbet reverse ridge step, smoothly demoulding when the mould is removed, and brushing the inner side of the hoisting template by using a demoulding machine before pouring;
thirdly, after the L-shaped outer rabbet reverse ridge step is formed, cleaning garbage such as floating ash on the L-shaped outer rabbet reverse ridge step, and carrying out mortar setting by using polymer waterproof mortar, wherein the mortar setting thickness is 1 cm;
and fourthly, arranging the lower end of the front side wall of the square tube flue on the front side step of the L-shaped outer tongue-and-groove reverse ridge step, arranging the lower end of the right side wall of the square tube flue on the right side step of the L-shaped outer tongue-and-groove reverse ridge step, enabling the left side wall of the square tube flue to be abutted to the left side shear wall of the kitchen position, enabling the rear side wall of the square tube flue to be abutted to the rear side shear wall of the kitchen position, and enabling the top end surface of the square tube flue to be abutted to the lower bottom surface of the upper concrete pouring floor slab.
The outer rabbet-shaped inverted ridge structure provided by the invention is suitable for construction of reserved holes of flues in kitchens and bathrooms, the problem that the traditional blocking hole is not tight in abutted seam and smoke backflow is easy to form is solved by integrally pouring the L-shaped outer rabbet-shaped inverted ridge step, the verticality of the flues is ensured, and the construction quality is improved.
