[0002] The building beam is a horizontal load-bearing component arranged along the transverse direction of the building (generally perpendicular to the longitudinal axis of the building). In modern buildings, most of the building beams in the form of traditional beams are concrete beams and steel beams. First, the weight of ordinary reinforced concrete beams is large, which is mainly due to the large density of concrete material and the need for large cross-sectional size to ensure structural strength. This not only increases the overall weight of the building and the requirement for foundation bearing, but also brings inconvenience in transportation and hoisting, increases the construction difficulty and cost. The solution is to optimize the concrete mix ratio or use lightweight concrete, but the former has limited effect, and the latter has high cost and may affect the structural durability. Second, ordinary steel beams have poor fire resistance. Steel material quickly loses strength at high temperatures, and heat easily softens steel beams due to the fast heat conduction of steel.

[0021] Please refer to Figures 1 to 4 As the first embodiment of the utility model: the cross section of crossbeam body 100 is I-shaped structure, and a plurality of accommodating cavities are formed in the recess one 101 of crossbeam body 100 by baffle 110, and the accommodating cavities of crossbeam body 100 are prefabricated and filled with concrete, and reinforcing plate one 120 is installed on the left side surface of crossbeam body 100 in horizontal position,

[0022] Reinforcing plate two 130 is installed on the right side surface of crossbeam body 100 in vertical position, and angle solid plate 140 is integrally arranged between the inner side surface of reinforcing plate two 130 and the bottom of recess two 102, and the corner of angle solid plate 140 is chamfered, and a plurality of threaded holes are evenly arranged on the surface of reinforcing plate one 120 and reinforcing plate two 130 respectively;
