Novel prefabricated precast concrete beam with steel joint
The invention relates to the field of prefabricated buildings, in particular to a novel prefabricated concrete beam with a steel joint. The novel prefabricated concrete beam comprises a steel framework; connecting parts are arranged at two ends of the steel framework; the steel framework comprises four parallel longitudinal bars; a plurality of rectangular stirrups are arranged among the longitudinal bars; the longitudinal bars are positioned at four corners of the stirrups; the distribution density of the stirrups close to a connecting part is greater than that of the stirrups in the middle of the steel framework; the connecting part comprises a connecting plate; flange steel plates are arranged on two side edges of the connecting plate and form an I-shaped structure; the longitudinal bars and the flange steel plates are welded and fixed through welding plates; end socket plates are further arranged between the flange steel plates and are perpendicular to the connecting plate; a concrete layer is poured on the steel framework between the end socket plates; a plurality of connecting holes are formed in the connecting plate; and the connecting plate can be directly connected with other steel structures through the connecting holes. By adopting the scheme, the precast concrete beam has the advantages of convenience in joint connection, reduction of manufacturing cost and convenience in market popularization.
本发明涉及装配式建筑领域，特指一种新型装配式带钢节点的预制混凝土梁，包括钢骨架，钢骨架两端为连接部，钢骨架包括四根平行的纵筋，纵筋之间设置有若干矩形的箍筋，纵筋位于箍筋的四个角上，靠近连接部的箍筋分布密度大于钢骨架中间部的箍筋分布密度；连接部包括连接板，连接板两侧边设置有翼缘钢板并形成工字型结构，纵筋与翼缘钢板之间通过焊接板焊接固定；翼缘钢板之间还设置有封头板，封头板与连接板垂直，在封头板之间的钢骨架上浇筑有混凝土层；连接板上开设有若干连接孔，通过连接孔可直接与其它钢结构连接。采用上述方案后，具有节点连接方便，有利于降低造价，便于市场推广的优点。
