Description
技术领域technical field
本发明涉及一种剪力墙，特别是一种预制钢筋混凝土剪力墙及施工方法。The invention relates to a shear wall, in particular to a prefabricated reinforced concrete shear wall and a construction method.
背景技术Background technique
剪力墙又称抗震墙或结构墙；在房屋或构筑物中主要承受风荷载或地震作用引起的水平荷载和竖向荷载的墙体。现有传统的剪力墙主要是钢筋混凝土结构，一般采用现浇混凝土的方式制成，其需要在现场捆扎钢筋骨架和浇筑混凝土，不仅施工速度慢，而且也难以保证浇筑质量；其次，混凝土梁的自重比较重，影响竖向构件和基础的造价，结构的抗震性能不高，同样的跨度和荷载条件下，混凝土梁的梁高较高，减少了建筑的净高，影响建筑的使用；而且混凝土梁上开洞构造复杂。随着绿色建筑和建筑工业化的发展，装配式建筑已逐步进入市场，装配式剪力墙开始逐渐替代传统的现浇混凝土剪力墙。现有的装配式剪力墙结构体系主要为钢板组合剪力墙，其连接方便，施工快捷，施工质量有保证；但是，钢板组合剪力墙的防火性能差，需要额外进行防火保护，造价较高，防火材料还占用建筑的使用面积，导致建筑物的使用效率不高。防火材料在后期装修的工程中容易被破坏掉，影响结构的防火安全性；同时，用钢量高，造价高。因此，现有的技术存在着无法同时兼顾造价低、连接方便和防火性能好的问题。Shear wall, also known as seismic wall or structural wall; a wall that mainly bears horizontal and vertical loads caused by wind loads or earthquakes in houses or structures. The existing traditional shear wall is mainly a reinforced concrete structure, which is generally made of cast-in-place concrete. It needs to bundle the steel frame and pour the concrete on site, which is not only slow in construction, but also difficult to ensure the pouring quality; secondly, the concrete beam The self-weight of the concrete beam is relatively heavy, which affects the cost of vertical components and foundations. The seismic performance of the structure is not high. Under the same span and load conditions, the beam height of the concrete beam is higher, which reduces the clear height of the building and affects the use of the building; and The structure of openings on concrete beams is complex. With the development of green buildings and building industrialization, prefabricated buildings have gradually entered the market, and prefabricated shear walls have begun to gradually replace traditional cast-in-place concrete shear walls. The existing prefabricated shear wall structure system is mainly steel plate composite shear wall, which is easy to connect, fast in construction, and guaranteed in construction quality; however, the fire resistance of steel plate composite shear wall is poor, additional fire protection is required, and the cost is relatively high. High, fireproof materials also occupy the usable area of the building, resulting in inefficient use of the building. Fireproof materials are easily destroyed in the later decoration project, which affects the fire safety of the structure; at the same time, the amount of steel used is high and the cost is high. Therefore, the existing technology has the problem of not being able to take into account low cost, convenient connection and good fire performance at the same time.
