Problems solved by technology

If the span of the beam is increased, if the longitudinal section of the beam is not enlarged, the beam will sink when the crane lifts heavy objects, which will seriously cause the beam to deform or even break

Embodiment 1

[0019] Such as figure 1 As shown, the beam body 1 is provided with a group of prestressed reinforcement ribs, and the group of prestressed reinforcement ribs is composed of two prestressed reinforcement structures 3, and is located on the cross section of the beam body 1 (that is, on the section shown in the figure) ), two prestressed reinforcement structures 3 are arranged obliquely and symmetrically, and the two ends of the prestressed reinforcement structures 3 are fixed to the beam body 1. In this embodiment, the prestressed reinforcement structure 3 is a prestressed reinforcement rib. In this group of prestressed reinforced structures, the upper ends of the two prestressed reinforced structures 3 are fixed to the upper part of the side of the beam body 1 by tension bolts 2, and the upper part of the side of the beam body 1 is correspondingly provided with connecting holes. In this group of prestressed reinforced structures, the lower ends of the two prestressed ribs are ...

Embodiment 2

[0021] The difference between the second embodiment and the first embodiment is that there are two sets of prestressed reinforcement structures inside the beam body 1, and the planes where the two sets of prestressed reinforcement structures are located are parallel to each other. All the other structures are the same as in Embodiment 1.

Abstract

The invention relates to a cable-stayed prestressed reinforcing rib type crane cross beam. The cross beam is provided with a cross beam body and is characterized in that one, two or more groups of prestressed reinforcing ribs are arranged in the cross beam body, wherein each group of prestressed reinforcing ribs consists of two prestressed reinforcing ribs and is positioned on the cross section ofthe cross beam body, the two prestressed reinforcing ribs are obliquely and symmetrically arranged, and two ends of the prestressed reinforcing ribs are fixed to the cross beam body.

Description

technical field [0001] The invention relates to a cable-stayed prestressed rib type crane beam. Background technique [0002] Cranes, also known as cranes, cranes, gantry cranes, and cranes, are indispensable hoisting equipment for factories. In use, the span of the crane beam should not be too large, otherwise, the beam is easy to bend. With the development of science and technology, the span of the factory building is getting bigger and bigger, which requires the span of the crane to increase. As the span of the crane increases, the longitudinal section of the crane beam needs to be increased accordingly to ensure the strength of the crane beam. If the span of the beam is increased, if the longitudinal section of the beam is not enlarged, the beam will sink when the crane lifts heavy objects, and in serious cases, the beam of the crane will be deformed or even broken. Contents of the invention [0003] The purpose of the present invention is to provide a cable-stayed ...
