在多层建筑浅基础中,由于层数变化、基础类型不同、新旧建筑的拼接等原因,需用沉降缝隔开。本文介绍３种浅基础沉降缝的构造方法。１悬挑方案适用于新旧建筑拼接处（图１）。图中１为挑梁,可根据需要在平面上布置几道;２为梁,当３为墙时作承墙梁用,３为柱时作连系梁用;３为承重 In the shallow foundation of multi-storey buildings, due to the change of the number of floors, different types of foundations, and the splicing of old and new buildings, it is necessary to separate them with settlement joints. This article describes the construction methods of three kinds of shallow foundation settlement joints. The overhanging scheme is applicable to the splices of old and new buildings (Figure 1). In the figure, 1 is a cantilever beam, and several paths can be arranged on the plane according to needs; 2 is a beam; when 3 is a wall, a wall beam is used; 3 is a tie beam; 3 is a weight bearing.
