Assembly type wood-bamboo frame-grid wall structure system suitable for village and town residences

Abstract

The invention discloses a low multi-layer assembly type wood-bamboo frame-grid wall structure suitable for village and town residences. The system comprises an external wood frame and an internal grid shear wall made of standard wood or raw bamboo, and wood beams and wood columns of the external wood frame are connected through slotted-in steel plates; an internal wood grid component and an external wood frame of the wood frame-wood grid shear wall structure are connected through a joint bar, and the joint bar serving as a middle component is in bolt connection with the wood grid component and is in angle steel connection with the external wood frame; and an internal bamboo grid component and an external wood frame of the wood frame-bamboo grid shear wall structure are hinged through lug plates at the ends of the internal bamboo grid component and the external wood frame, and the slotted-in steel plates penetrate through the wood beams or the wood columns and are fixed with the wood beams or the wood columns through split bolts. The assembly type wood-bamboo frame-grid wall structure system has good anti-seismic performance and high environmental protection benefits, and is convenient to construct and low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of construction engineering and relates to a novel frame-shear wall structure, in particular to an assembled wood and bamboo frame-grid wall structure suitable for village and town residences. Background technique [0002] In recent years, the population of villages and towns in my country has gradually shifted to cities. However, due to the large population base of our country, the population of villages and towns is still huge, and the yearning of rural residents for a good living environment has become more and more urgent with the development of the economy. According to the Urban and Rural Construction Statistical Yearbook issued by the Ministry of Housing and Urban-Rural Development of the People's Republic of China, since the 1990s, the investment in village and town housing construction has been increasing year by year. Correspondingly, there is a steady upward trend. As of the end of 2018, the actua...

Problems solved by technology

According to the Urban and Rural Construction Statistical Yearbook issued by the Ministry of Housing and Urban-Rural Development of the People's Republic of China, since the 1990s, the investment in village and town housing construction has been increasing year by year. Correspondingly, there is a steady upward trend. As of the end of 2018, the actual construction area of ​​villages and towns has reached 25.22 billion square meters. However, there are a series of problems in the commonly used villages and towns houses: first, most of the villagers’ self-built houses are not fully earthquake-resistant. Design, There is no effective earthquake-resistant structure, and the damage is serious under strong earthquakes. Partial or even overall collapse may occur and the safety of people's lives and property cannot be guaranteed. According to previous earthquake damage surveys, the damage rate of villagers' self-built houses in villages and towns is much higher than that of Urban buildings; in addition, concrete, bricks and other building materials commonly used in village and town buildings also have large dust and serious construction pollution during the construction process, and it is difficult to recycle and reuse building materials, resulting in waste of resources and energy.

However, with the development of science and technology, engineered wood and engineered bamboo with more stable mechanical properties have gradually replaced logs and bamboo as the main building materials for modern bamboo-wood structures, but engineered wood and engineered bamboo need to be processed by logs and bamboo. It is manufactured through a series of processing, which increases the cost to a certain extent and limits the use of both in self-built residential structures in villages and towns
