Building Frame Structure Having Edge Beam and Construction Method Thereof

Content Provider	The Lens
Abstract	Disclosed is a building frame structure having an edge beam and a construction method thereof. The frame structure includes: a main frame structure and a cantilever beam provided outside of the main frame structure, a beam supported by the cantilever beam, and an outer floor disposed between the main frame structure and the edge beam. The edge beam and the cantilever beam are preforms reserved with exposed reinforcing bars, respectively. The edge beam is provided thereon with a vertical sideboard and a temporary safety rail. The cantilever beam is a beam-shell structure provided with an inner recess. The outer floor is a laminated plate, a lower part of which is a preformed plate. The preformed plate, the edge beam, and the cantilever beam are connected to each other by concrete cast in situ at respective top portions thereof.

Claim	A building frame structure having an edge beam, comprising: a main frame structure ( 10 ) which includes a column ( 1 ), a beam ( 2 ), and an inner floor ( 31 ), a cantilever beam ( 5 ) provided outside of the main frame structure ( 10 ), an edge beam ( 6 ) supported by the cantilever beam ( 5 ), and an outer floor ( 32 ) disposed between the main frame structure ( 10 ) and the edge beam ( 6 ), wherein the edge beam ( 6 ) is a preform reserved with an exposed reinforcing bar, the edge beam ( 6 ) being provided thereon with a vertical sideboard ( 61 ) and a temporary safety rail ( 62 ); wherein the cantilever beam ( 5 ) is a preform reserved with an exposed reinforcing bar, the cantilever beam ( 5 ) having a beam-shell structure provided with an inner recess; wherein the outer floor ( 32 ) is a laminated plate, a lower part of which is a preformed plate ( 321 ); and wherein the preformed plate ( 321 ), the edge beam ( 6 ), and the cantilever beam ( 5 ) are connected to each other by concrete cast in situ at respective top portions thereof. The building frame structure having an edge beam according to claim 1 , wherein multiple notches ( 63 ) are provided in the vertical sideboard ( 61 ) of the edge beam ( 6 ), and a curtain wall pre-insert is arranged in advance at each of the notches ( 63 ). The building frame structure having an edge beam according to claim 2 , wherein at a construction site, the notches ( 63 ) are filled with concrete, to form a curtain wall firewall together with the vertical sideboard ( 61 ). The building frame structure having an edge beam according to claim 1 , wherein a periphery of a corner outer floor at each corner of a building is connected to the beam-shell structure provided with a recess therein. The building frame structure having an edge beam according to claim 1 . wherein the edge beam ( 6 ) and its vertical sideboard ( 61 ) are formed into one preform, and the temporary safety rail ( 62 ) is secured to the vertical sideboard ( 61 ) by means of a connector pre-embedded in the vertical sideboard ( 61 ). The building frame structure having an edge beam according to claim 1 , wherein an inner floor ( 31 ) of the main frame structure ( 10 ) is a laminated plate, a lower part of which is a preformed plate, wherein the beam ( 2 ) is a preform provided, at a top portion thereof, with a recess, and reserved with an exposed reinforcing bar, and wherein a preformed plate of the inner floor ( 31 ) and the beam ( 2 ) are connected, by concrete cast in situ at respective top portions thereof, to the outer floor ( 32 ), the edge beam ( 6 ), and the cantilever beam ( 5 ). A construction method of the building frame structure having an edge beam according to claim 1 , comprising: step A): cleaning up an N th floor, and preparing for construction on a current floor; step B): mounting and securing, by means of a completed column ( 1 ), a support frame of a cantilever structure provided outside of a main frame structure ( 10 ), and hanging a safety net ( 9 ); step C): mounting a support frame ( 81 ), and preparing for lifting of a preformed beam and a preformed plate; step D): lifting the preformed beam ( 2 ) and a preformed plate of the main frame structure ( 10 ), mounting, by means of the completed column ( 1 ), a reinforced oblique rod ( 82 ) of the edge beam, and lifting a preformed cantilever beam ( 5 ), a preformed edge beam ( 6 ), and a preformed plate ( 321 ) of the outer floor ( 32 ); step E): strapping reinforcing bars on the preformed beam ( 2 ), the preformed plate of the main frame structure ( 10 ), the preformed plate of the outer floor ( 32 ), the preformed cantilever beam ( 5 ). and the preformed edge beam ( 6 ), respectively, to connect them together by means of cast-in-site concrete; and step F): removing the support frame ( 81 ) and the safety net ( 9 ) of the N th floor when the cast-in-situ concrete achieves required strength. The construction method of the building frame structure having an edge beam according to claim 7 , wherein in step D), the preformed edge beam ( 6 ) and its vertical sideboard ( 61 ) are lifted first, followed by mounting of a temporary safety rail ( 62 ) by means of a connector pre-embedded in the vertical sideboard ( 61 ). A construction method of the building frame structure having an edge beam according to claim 7 with series preforms, wherein in step E), before concrete is cast in situ, an independent support piece ( 83 ) is established below the preformed beam ( 2 ) and the preformed plate. The construction method of the building frame structure having an edge beam according to claim 7 with series preforms, wherein the vertical sideboard ( 61 ) of the edge beam is provided therein with multiple notches ( 63 ), at which curtain wall pre-inserts are arranged in advance, and wherein in step E), concrete is cast into the notches ( 63 ).
