Description
技术领域technical field
本实用新型属于建筑工程技术领域,特别是涉及一种低多层钢结构住宅体系。The utility model belongs to the technical field of construction engineering, in particular to a low multi-storey steel structure residential system.
背景技术Background technique
目前我国城镇化比例还偏低,在市区范围外大面积范围内建筑均以低多层村镇住房为主,且大多数农房都为自建,从建造方式上其建筑材料常需求部件简单、就地选材或居民自建等特点,且整体性和抗震性差;从结构特点上其大都为1-3层低层住宅,使用功能和荷载类型较为简单,材料大都采用生土、红砖、竹木或石土结构。At present, the proportion of urbanization in my country is still relatively low. The buildings in large areas outside the urban area are mainly low-storey village houses, and most of the rural houses are self-built. From the construction method, the building materials often require simple components. , on-site selection of materials or self-built by residents, etc., and poor integrity and earthquake resistance; in terms of structural characteristics, most of them are low-rise residences with 1-3 floors, the use functions and load types are relatively simple, and most of the materials are raw soil, red brick, bamboo Wooden or stone-earth structures.
近年来我国开展村镇改造和美丽乡村建设计划,将对于村镇建筑和规划进行整体提升改造,以改善人民居住条件。同时在我国对于建筑结构的抗震要求逐步提升的背景下,研发适用于村镇住宅使用功能特点,具有较好的抗侧抗震性能,且低成本可快速装配及快速施工的低多层装配式钢结构住宅具有十分重要的现实意义。In recent years, my country has carried out village and town reconstruction and beautiful countryside construction plans, and will carry out overall upgrading and renovation of village and town buildings and planning to improve people's living conditions. At the same time, under the background that my country's seismic requirements for building structures are gradually increasing, research and develop low-level prefabricated steel structures that are suitable for use in villages and towns, have good lateral seismic performance, and can be quickly assembled and constructed at low cost. Housing is of great practical significance.
现有村镇钢结构住宅大都采用冷弯薄壁结构体系,其主体结构采用轻钢龙骨骨架,配以轻钢龙骨复合墙板。该结构体系中轻钢龙骨复合墙板作为竖向承重墙,导致内部墙板施工完成后不能随意改变或拆除,导致房屋使用功能受到限制。Most of the existing steel structure houses in villages and towns adopt cold-formed thin-walled structural system, and the main structure adopts light steel keel frame and light steel keel composite wallboard. In this structural system, the light steel keel composite wall panel is used as a vertical load-bearing wall, so that the internal wall panel cannot be changed or removed at will after the construction is completed, resulting in the limited use of the house.
而且采用传统框架结构作为低多层村镇住宅骨架时,梁柱构件除需满足竖向承重外还需要提供足够的抗侧刚度,构件和节点需要能够提供足够的抗弯承载能力,因此尺寸较大,导致建造成本较高,在农村地区及村镇推广受限。并且框架钢结构应用时节点大都需要刚接,以提供足够的结构刚度和抗侧能力,对于节点施工要求较高,而村镇地区施工质量常难以保障,从而存在安全隐患。Moreover, when the traditional frame structure is used as the skeleton of low-level village houses, the beam-column members need to provide sufficient lateral stiffness in addition to vertical load-bearing, and the members and nodes need to provide sufficient flexural bearing capacity, so the size is large. , resulting in higher construction costs and limited promotion in rural areas and villages. In addition, when the frame steel structure is applied, most of the nodes need to be rigidly connected to provide sufficient structural rigidity and lateral resistance. The requirements for node construction are relatively high, and the construction quality in villages and towns is often difficult to guarantee, resulting in potential safety hazards.
