As shown in fig. 1 and 2, the method for constructing unequal-height roof of high-rise steel structure residential building according to the embodiment of the invention comprises the following steps:
step S1, firstly building a core tube 100, and pouring a core tube roofing concrete layer 110 on the built core tube 100;
step S2, constructing an outer frame 200, constructing the outer frame 200 and a core tube 100 with unequal heights, arranging the outer frame 200 along the periphery of the core tube 100, pouring an outer frame roofing concrete layer 210 after the outer frame 200 is constructed to the height of a roof layer, forming a roof layer by the core tube roofing concrete layer 110 and the outer frame roofing concrete layer 210 together, and forming an annular construction joint 300 between the core tube roofing concrete layer 110 and the outer frame roofing concrete layer 210;
step S3, constructing a slope finding concrete layer 400, wherein the slope finding concrete layer 400 is covered on the roof layer of the roof, the slope finding surface of the slope finding concrete layer 400 is obliquely and downwards arranged from the core tube roof concrete layer 110 to the outer frame roof concrete layer 210, the slope finding concrete layer 400 is provided with an impermeable section 410, the impermeable section 410 is correspondingly arranged on the construction joint 300, and a reinforced connecting structural member 500 is arranged in the impermeable section 410 to improve the anti-cracking structural strength of the impermeable section 410.
In the construction process, the core tube 100 is constructed ahead of the outer frame 200, and after the core tube 100 is constructed, the core tube roof concrete layer 110 on the core tube 100 is poured firstly.
After the outer frame 200 is constructed to the outer frame roofing concrete layer 210, the outer frame roofing concrete layer 210 is poured, and the core tube roofing concrete layer 110 and the outer frame roofing concrete layer 210 jointly form a complete roof layer. After the outer frame roofing concrete layer 210 is poured, the outer frame roofing concrete layer 210 is cured.
After the outer frame roof concrete layer 210 is cured, the slope finding concrete layer 400 is constructed. The impervious concrete of C30P6 is used for slope finding to form a slope finding concrete layer 400 on the roof layer of the roof.
The core barrel 100 and the outer frame 200 adopt construction modes with unequal heights, and the condition that workers are idle due to overlong construction idle time of a roof concrete layer of the core barrel is avoided.
After the core tube roofing concrete layer 110 and the outer frame roofing concrete layer 210 are poured, the construction joint 300 area is covered by constructing the slope finding concrete layer 400, and the anti-seepage section 410 is reinforced by arranging the reinforced connecting structural member 500, so that the stress at the construction joint 300 is prevented from being transferred to the anti-seepage section 410, and the anti-seepage section 410 is prevented from cracking. The slope finding concrete layer 400 guides rainwater on the roof to the outside of the roof, and the seepage-proofing effect is achieved by covering the construction joint 300 area.
In some embodiments of the present invention, the reinforced connection structure 500 includes at least one layer of bidirectional reinforcing mesh 510, the bidirectional reinforcing mesh 510 is formed by interweaving a plurality of reinforcing bars, and the bidirectional reinforcing mesh 510 spans the construction joint 300.
Referring to fig. 3, the width of the bidirectional mesh sheet 510 needs to be greater than the width of the construction joint 300, and the wider the width of the bidirectional mesh sheet 510, the more dispersed the stress. In this embodiment, the width of the bidirectional mesh sheet 510 is 0.5m-1.5 m. A bi-directional rebar mesh 510 is placed along the construction joint 300. The bidirectional reinforcing mesh 510 is formed by longitudinally and transversely interweaving longitudinally and transversely arranged reinforcing steel bars, and comprises both tension reinforcing steel bars and compression reinforcing steel bars. The bidirectional reinforcing mesh 510 can enhance the crack resistance of the seepage-proofing section 410, and prevent the seepage-proofing section 410 from cracking due to the tensile stress of the seepage-proofing section 410 expanding towards two sides from the construction joint 300, which causes the seepage-proofing section 410 to lose the seepage-proofing function.
In a further embodiment of the present invention, the reinforced connecting structure 500 includes two layers of the bidirectional reinforcing mesh 510 disposed above each other.
By arranging two layers of bidirectional reinforcing mesh sheets 510 which are arranged up and down, a certain staggered distribution exists between the two layers of bidirectional reinforcing mesh sheets 510, so that the tensile stress from the expansion of the construction joint 300 to two sides can be further dispersed. Thereby further improving the crack resistance of the barrier section 410.
In a further embodiment of the present invention, the width of the bidirectional mesh 510 is 0.5m to 1.5 m. The width of the bidirectional reinforcing mesh 510 needs to be ensured to be larger than the width of the construction joint 300, and the wider the width of the bidirectional reinforcing mesh 510 is, the more dispersed the stress is.
In a further embodiment of the present invention, the method further includes step S21 of setting a connection steel bar 600, before the outer frame roofing concrete layer 210 is poured, a circle of burrs are formed around the core tube roofing concrete layer 110, then the connection steel bar 600 is implanted, one end of the connection steel bar 600 is implanted into the core tube roofing concrete layer 110 and connected with the steel bar structure in the core tube roofing concrete layer 110, the other end of the connection steel bar 600 is connected with the steel bar structure of the outer frame 200, and then the outer frame roofing concrete layer 210 is poured.
Before the outer frame roofing concrete layer 210 is poured, a circle of the periphery of the core tube roofing concrete layer 110 is chiseled sufficiently, then the connecting steel bars 600 are implanted, and the implanted ends are connected with the steel bar structures in the core tube roofing concrete layer 110. The other end of the connecting reinforcement 600 is connected to the reinforcement structure in the core tube roofing concrete layer 110, and then the outer frame roofing concrete layer 210 is poured. The outer frame roofing concrete layer 210 and the core tube roofing concrete layer 110 are connected by arranging the connecting steel bars 600, so that the tensile stress of the expansion of the construction joint 300 to two sides is resisted, and the expansion stress of the construction joint 300 is reduced. The tensile stress experienced by the barrier section 410 may also be reduced, increasing the useful life of the barrier section 410.
In a further embodiment of the present invention, the method further includes step S4, setting a reverse threshold of the core cylinder 100, where the reverse threshold of the core cylinder 100 is set on the slope finding concrete layer 400 near the inner side of the slope finding concrete layer 400, the reverse threshold of the core cylinder 100 is set along the indoor boundary of the core cylinder 100, and the height of the reverse threshold of the core cylinder 100 is higher than the height of the slope finding concrete layer 400.
By providing the core barrel reverse threshold 700 along the indoor boundary of the core barrel 100, the core barrel reverse threshold 700 may prevent rainwater from entering the indoor of the core barrel 100 in reverse flow in some rainy weather.
In a further embodiment of the present invention, the slope of the slope finding surface of the slope finding concrete layer 400 is 1% to 3%.
The slope finding surface of the slope finding coagulation layer 400 needs to be set as an inclined surface so as to be capable of finishing the guiding effect on water, but if the slope finding surface of the slope finding coagulation layer 400 is too small, the effect of guiding rainwater is not ideal. The thickness of the slope finding coagulation layer 400 from the core tube 100 to the outer frame 200 is thinner and thinner, but the difference of the thickness of the slope finding coagulation layer 400 is larger due to the overlarge slope of the slope finding surface, and the strength of the slope finding coagulation layer 400 is reduced. Particularly, when the thickness difference of the barrier sections 410 is too large, the strength of the barrier sections 410 is greatly affected. The slope of the slope finding surface of the slope finding concrete layer 400 is 1% -3%. The rainwater guiding function can be achieved, and the influence on the strength of the seepage-proof section 410 is avoided because the thickness difference of the seepage-proof section 410 is too large.
