Embodiment Construction

[0036] Please refer to the attached figure 2 to attach Figure 9 As shown, the present invention is a prefabricated fireproof composite building component, which includes H-shaped steel 1, said H-shaped steel 1 is welded by web 11 and flanges 12 arranged at both ends of web 11 and perpendicular to web 11 made. A tie steel bar 2 is welded between the flanges 12 .

[0037] Concrete 3 is poured between the flanges 12 and on both sides of the web 11 , and the concrete 3 is poured to be flush with the sides of the flanges 12 .

[0038] The embedded part 4 is welded on the flange 12 . A fireproof board 5 is hung on the embedded part 4 , and the fireproof board 5 and the flange 12 are bonded by polymer mortar 6 . Specifically, the fireproof board 5 includes a bottom plate 51 and side plates 52 arranged on both sides of the bottom plate 51; A hanging member 54 is disposed on the inner side of the side plate 52 .

[0039] The concrete 3 is provided with a plastering mortar layer...

Abstract

The invention relates to an assembled fireproof combined building component and a construction method thereof. The assembled fireproof combined building component comprises H-shaped steel, the H-shaped steel comprise a web and flanges which are arranged at the two ends of the web and are perpendicular to the web; a pulling steel bar is welded between the flanges; concrete is casted between the flanges and at the two sides of the web, and is casted to be flush with the sides of the flanges; an embedded part is welded to each flange; fireproof boards are hung on the embedded parts, and the portion between the fireproof boards and the flanges is cemented through polymer mortar; a plastering mortar layer is arranged outside the concrete; the plastering mortar layer is flush with the outer edges of the fireproof boards. By means of the assembled fireproof combined building component and the construction method thereof, the purposes that the construction is safe and reliable, convenient, andlow in cost can be achieved.

Description

【Technical field】 [0001] The invention relates to a building component and a construction method thereof, in particular to a prefabricated fireproof composite building component and a construction method thereof, belonging to the technical field of prefabricated buildings. 【Background technique】 [0002] There are more and more applications of steel structures and composite structures in my country, and more and more damages to such building structures are caused by fires. It is imperative to ensure the safety of structures against fire and the economy of fire prevention measures. A common fire prevention measure is spraying fire retardant coatings. However, the price of fire retardant coatings is relatively high, and the use of fire retardant coatings will result in higher construction costs and increase the number of procedures for on-site operations. [0003] The steel-concrete partial composite member is a new type of composite member proposed in Europe in the 1980s. The...
