Description
技术领域technical field
本发明涉及一种适用于框支剪力墙结构逆作法施工的连接节点。The invention relates to a connection node suitable for reverse construction of a frame-supported shear wall structure.
背景技术Background technique
随着我国城市化进程不断加深，城市内建筑场地逐渐变得狭小，实际的市场需求对建筑施工工期提出严格要求，有时甚至十分紧张，而狭小的施工场地尤其制约着施工进展，影响建筑工期。逆作法施工由于利用建筑的地下结构作为基坑支撑体系，不需要设置临时支撑，并可以在基坑开挖、地下室施工的同时进行地面结构的施工，有效缩短了建筑工期，节约了建筑场地，因而在当今的城市建设中得到了越来越多的应用。逆作法设计、施工过程中，需设置逆作法支撑构件作为在地下室与基础施工完成前承载上部结构荷载的竖向结构构件。With the continuous deepening of urbanization in our country, the construction site in the city is gradually becoming narrower. The actual market demand puts forward strict requirements on the construction period, sometimes even very tight, and the narrow construction site especially restricts the construction progress and affects the construction period. The reverse construction method uses the underground structure of the building as the support system of the foundation pit, so there is no need to set up temporary supports, and the construction of the ground structure can be carried out at the same time as the excavation of the foundation pit and the construction of the basement, which effectively shortens the construction period and saves the construction site. Therefore, it has been more and more used in today's urban construction. During the design and construction process of the upside-down method, it is necessary to set up the upside-down method support members as the vertical structural members that bear the load of the upper structure before the basement and foundation construction are completed.
对于框支剪力墙结构，当其转换层位置在三层楼面或三层楼面以下时，以转换层楼面作为逆作法的分界面，可进一步缩短建筑工期，即：先完成转换层楼面的施工，然后在转换层同时向上进行上部结构施工、向下进行下部结构施工。在此应用场景下，逆作法支撑构件的上端部应伸至转换层并与转换梁连接；并且，转换梁应采用型钢混凝土组合结构(包括钢箱梁和钢骨混凝土梁)，不仅满足建筑空间及功能要求、更能进一步节省建筑工期以及降低转换层高支模的难度。For the frame-supported shear wall structure, when the transfer floor is at or below the third floor, the transfer floor is used as the interface of the reverse method, which can further shorten the construction period, that is, the transfer floor is completed first The construction of the floor, and then carry out the construction of the superstructure upwards and the construction of the substructure downwards at the same time at the transfer floor. In this application scenario, the upper end of the upside-down supporting member should extend to the transfer floor and be connected with the transfer beam; moreover, the transfer beam should adopt a steel-concrete composite structure (including steel box girders and steel-reinforced concrete beams), which not only meets the needs of building space and functions Requirements, can further save the construction period and reduce the difficulty of converting storey formwork.
现有的逆作法施工中，逆作法支撑构件与型钢混凝土组合结构转换梁的连接节点构造为：使用单根的圆形钢管柱作为逆作法支撑构件，使用型钢混凝土组合结构梁作为转换梁，单根的圆形钢管柱通过环板或牛腿等方式与型钢混凝土组合结构梁连接；其中，采用圆形钢管柱作为逆作法支撑构件具有受力简单明确、使用成本经济的优点。In the existing upside-down method construction, the connection node structure between the upside-down method support member and the steel-concrete composite structure transfer beam is as follows: a single circular steel pipe column is used as the upside-down method support member, and the steel-concrete composite structure beam is used as the transfer beam. The circular steel pipe column at the root is connected to the steel-concrete composite structural beam through ring plates or corbels; among them, the circular steel pipe column is used as the supporting member of the inverse method, which has the advantages of simple and clear force and low cost of use.
上述现有的连接节点应用于框支剪力墙结构部分逆作法施工时存在以下不足：The above-mentioned existing connection nodes have the following deficiencies when they are applied to the frame-supported shear wall structure part of the reverse construction method:
第一，对框支剪力墙结构高层建筑来说，其上部结构的荷重较大，而由于作为逆作法支撑构件的圆形钢管柱埋于框支剪力墙结构的剪力墙中，使得该圆形钢管柱的管径受到剪力墙厚度的限制，单根的圆形钢管柱难以满足支撑高层建筑上部结构荷重的要求，因此，现有的连接节点不适用于框支剪力墙结构高层建筑以转换层楼面为分界面的逆作法施工；First, for a high-rise building with a frame-supported shear wall structure, the load on the superstructure is relatively large, and because the circular steel pipe column used as the support member of the reverse method is buried in the shear wall of the frame-supported shear wall structure, the The diameter of the circular steel pipe column is limited by the thickness of the shear wall, and it is difficult for a single circular steel pipe column to meet the load requirements of supporting the upper structure of a high-rise building. Therefore, the existing connection nodes are not suitable for frame-supported shear wall structures Inverse construction of high-rise buildings with the transfer floor as the interface;
第二，解决上述第一点不足的通常思路是把单根的圆形钢管柱替换为多根圆形钢管柱，但由此又带来了新的问题：由于型钢混凝土组合结构转换梁的钢构件截面较大，受到剪力墙厚度限制的圆形钢管柱截面则小而细，在采用现有技术的环板或牛腿等连接方式的情况下，转换梁需要分别与多根圆形钢管柱进行连接，使得该转换梁与逆作法支撑构件之间的连接十分不便，传力复杂、施工难度大，连接可靠性低。Second, the general idea to solve the above-mentioned first point is to replace a single circular steel pipe column with multiple circular steel pipe columns, but this brings new problems: due to the steel structure of the steel concrete composite structure conversion beam The section of the member is large, and the section of the circular steel pipe column limited by the thickness of the shear wall is small and thin. In the case of using the existing connection methods such as ring plate or corbel, the transfer beam needs to be connected with multiple circular steel pipes respectively. The column is connected, which makes the connection between the transfer beam and the supporting member of the reverse method very inconvenient, the force transmission is complicated, the construction is difficult, and the connection reliability is low.
