Inverted T-shaped steel-wood-concrete composite beam and construction method thereof
The invention discloses an inverted-T-shaped steel-wood-concrete composite beam and a construction method thereof. The inverted-T-shaped steel-wood-concrete composite beam comprises a reinforced concrete plate and an inverted-T-shaped steel beam, and the top of a web of the inverted-T-shaped steel beam is fixedly embedded into the reinforced concrete plate; grooves are defined by the two sides of the inverted-T-shaped steel beam and the bottom side of the reinforced concrete plate correspondingly, and the grooves are fixedly filled with wood beams. When the inverted-T-shaped steel-wood-concrete composite beam bears load, the inverted-T-shaped steel beam and the wood beams bear tensile force, pressure is mainly borne by the reinforced concrete plate, and the advantages that the tensile strength of the wood beam and the inverted-T-shaped steel beam is high and the compressive strength of the reinforced concrete plate is high can be brought into full play; the integrity is good, the bearing capacity of the composite beam can be greatly improved, and the deflection is reduced; the structure is simple and assembling is easy; due to the existence of the wood beam, the direct fire area of the inverted-T-shaped steel beam in a fire disaster is reduced, and the fire resistance is greatly improved.
本发明公开了一种倒T形钢‑木‑混凝土组合梁及其施工方法，所述倒T形钢‑木‑混凝土组合梁包括钢筋混凝土板和倒T形钢梁，所述倒T形钢梁的腹板顶部固定嵌入于钢筋混凝土板内，所述倒T形钢梁的两侧分别与钢筋混凝土板的底侧之间围成凹槽，所述凹槽内固定填充有木梁。该倒T形钢‑木‑混凝土组合梁承受荷载时，主要由倒T形钢梁和木梁承受拉力，而压力主要由钢筋混凝土板承受，能充分发挥木梁和倒T形钢梁抗拉强度高与钢筋混凝土板抗压强度高的优势；整体性好，可大幅度提升组合梁的承载力、减少挠度；构造简单、易于装配；木梁的存在减少了火灾时倒T形钢梁的直接受火面积，大大提高了抗火能力。
