Problems solved by technology

[0005] In view of the above-mentioned related technologies, the inventor believes that: the above-mentioned subway prestressed beam body only realizes the stress support to the beam body by installing prestressed tendons in the prestressed tunnel, resulting in the low strength of the prestressed beam body and the occurrence of cracks in the beam body. Uneven distribution of prestress

Abstract

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.

Description

technical field [0001] The present application relates to the field of concrete beams, in particular to a reinforced subway prestressed beam body and a manufacturing method thereof. Background technique [0002] Prestressed beams, that is, prestressed concrete beams, are commonly used in construction beam construction in recent years. Prestressed concrete structural members generally form rebound extrusion by stretching prestressed tendons, so that the cross-section of the concrete is internal before it is put into use. It is subject to a certain internal pressure, which is used to partially or completely offset the stress formed due to the use of load. It can improve the performance of cracks and deformation of structural components, and the tensile stress and the compressive stress in the concrete just form a self-balancing system, making the stress of the concrete structure more reasonable. [0003] Prestressed concrete beams are pre-applied to the beams to generate nega...
