Novel combined stone beam

Abstract

The invention discloses a novel combined stone beam. The stone beam comprises a stone beam body, wherein a tensile region of the stone beam body is provided with a groove in the longitudinal direction of the stone beam body; a reinforcement material under a certain horizontal prestressing force is arranged in the groove in the longitudinal direction; the reinforcement material is fixed in the groove in a bonding way through a bonding material; and both ends of the reinforcement material are firmly fixed on both longitudinal ends of the stone beam body respectively through anchor devices. Compared with the prior art, the combined stone beam substantially increases the cracking moment, bending rigidity and anti-bending bearing capacity of the stone beam by embedding the high-strength tensile reinforcement material in the tensile region of the stone beam body and applying prestressing force and anchoring. Moreover, the combined stone beam can be applied in a beam-type stone-structure member of larger span and has the advantages of great width, high bearing capacity, no damages to stone-structure style and features and beauty, and the like; and therefore, the combined stone beam can be used in a newly-built stone-structure project and the reinforcement of an existing stone structure.

Description

technical field [0001] The invention relates to a composite stone beam, which can be applied to the construction of beam-type stone bridges, stone structure buildings, porches, archways and other structures in civil engineering and the reinforcement and transformation of existing stone beams. Background technique [0002] Stone structure is one of the oldest structural forms in our country and is widely used in bridges and house structures. The biggest advantages of granite stone structure materials are high compressive strength, good durability, and the advantages of natural texture and beauty. Stone structures have a long history in civil engineering in my country. The most famous ancient stone structures include Zhaozhou Bridge (arch structure) in Zhao County, Hebei Province, Song Dynasty Luoyang Bridge (beam structure) in Quanzhou, Fujian, and Kaiyuan Temple in Quanzhou. East and West Twin Towers, etc. In some areas of our country, especially in southern Fujian, due to ...

AI Technical Summary

Problems solved by technology

Although it is also used as a flexural member such as beams and slabs, it is often too bulky due to the need for a high section, not only has a low flexural bearing capacity, but also has a greater risk of brittle failure, thus limiting the scope of application of granite stone.
