Reinforced type subway prestressed beam body and manufacturing method thereof
The invention relates to the field of concrete beams, in particular to a reinforced type subway prestressed beam body and a manufacturing method thereof. The reinforced type subway prestressed beam body comprises two first concrete beams and second concrete beams, the two first concrete beams are oppositely arranged, the opposite side faces of the two first concrete beams are each provided with a prestressed semi-hole channel, the two prestressed semi-hole channels are combined into a prestressed hole channel, first prestressed tendons are arranged in the prestressed hole channel in a penetrating mode, the two second concrete beams are oppositely arranged, the first concrete beams and the second concrete beams are attached in a one-to-one correspondence mode, the opposite side faces of the first concrete beams and the corresponding second concrete beams are each provided with a reinforcing semi-hole channel, the two reinforcing semi-hole channels are combined into a reinforcing hole channel, and second prestressed tendons are arranged in the reinforcing hole channels in a penetrating mode. The manufacturing method of the reinforced type subway prestressed beam body comprises the steps of beam body manufacturing, bending, mounting, filling and stuffing. The reinforced type subway prestressed beam body has the effects of improving the strength of a subway prestressed concrete beam and weakening noise pollution.
本申请涉及混凝土梁的领域，尤其是涉及一种加固型地铁预应力梁体及其制造方法。加固型地铁预应力梁体包括第一混凝土梁、第二混凝土梁，第一混凝土梁相对设有两个，两个第一混凝土梁相向的侧面均开有预应力半孔道，两个预应力半孔道组合为预应力孔道，预应力孔道内穿设有第一预应力筋，第二混凝土梁相对设有两个，第一混凝土梁与第二混凝土梁一一对应贴合，第一混凝土梁与对应的第二混凝土梁相向的侧面均开有加固半孔道，两个加固半孔道组合为加固孔道，加固孔道内穿设有第二预应力筋。加固型地铁预应力梁体的制造方法为制作梁体→弯折→安装→填充→填塞。本申请具有提高地铁预应力混凝土梁的强度,同时减弱噪声污染的效果。
