A new type of extension device for prestressed continuous bamboo and wood beams

Abstract

The invention discloses a novel pre-stressed continuous bamboo-wood beam popularizing device, relates to a continuous beam, and aims to solve problems that most of existing glued bamboo-wood beams are simply supported and prone to brittle failures, the material strength cannot be fully utilized and deformation is higher. U-shaped end connecting pieces (11) are fixed at two ends of each bamboo-wood material (1), and every two adjacent bamboo-wood materials (1) are connected through the U-shaped end connecting pieces (11); integrated anchorage units (5) are fixed on top plates of the U-shaped end connecting pieces (11); turning and pressure-bearing wheels (2) are arranged on lower end surfaces of the bamboo-wood materials (1); pre-stressed steel strands (3) are distributed on front and back sides of the bamboo-wood materials (1), strand types are controlled by the turning and pressure-bearing wheels (2), bent strands are formed, and the pre-stressed steel strands (3) are anchored on the integrated anchorage units (5). With the adoption of the popularizing device, the applying speed of a modern bamboo-wood structure in a project is increased, and the bamboo-wood structure is effectively popularized.

Description

technical field [0001] The invention relates to a continuous beam, in particular to a prestressed continuous bamboo-wood beam, which belongs to the field of civil engineering. Background technique [0002] The study of prestressed glued bamboo and wood structures is of great significance: "National Medium and Long-Term Science and Technology Development Program (2006-2020)" Article 4, Article 20 states that "focus on research and development of high-efficiency, low-cost, large-scale cultivation of agricultural and forestry biomass , collection and transformation of key technologies", the prestressed glued bamboo-wood string beam floor structure system is another important form of prefabricated buildings, its research, demonstration and promotion belong to the efficient use of agricultural and forestry biomass materials in my country, and the National Development and Reform Commission, The spirit of the "Green Building Action Plan" vigorously advocated by the Ministry of Housin...

AI Technical Summary

Problems solved by technology

[0013] In order to solve the problems that the glued bamboo and wooden beams are mostly simply supported, the damage is brittle, the material strength cannot be fully utilized, and the deformation is relatively large, the present invention further provides a new type of prestressed continuous bamboo and wooden beam extension device, which will prestress Stress technology extends from simply supported beams to continuous beams and frame beams, and then forms a prestressed glued bamboo and wood floor structure system
