Structure of lower suspended beam and construction method

The invention relates to the technical field of door and window opening structure construction, and discloses a structure of a lower suspended beam and a construction method. The first filling piece is located in a gap between the lintel and the door and window frame, the top is fixedly connected with the bottom of the lintel through a first fastener, and the bottom abuts against the top of the door and window frame. The decorative layer is located in a gap between the lintel and the door and window frame and fixed to the side, close to the inner wall, of the first filling piece. According to the door and window frame, the construction technology is simple, concrete curing is not needed, the work amount is small, operation is easy, construction is convenient, manpower and material resources are saved, and the construction duration is shortened. 本发明涉及门窗洞口结构施工技术领域，公开了一种下挂梁的结构及施工方法，包括第一填充件和装饰层；第一填充件位于过梁与门窗框之间的空隙中，顶部通过第一紧固件与过梁的底部固定连接，底部与门窗框的顶部抵接；装饰层位于过梁与门窗框之间的空隙中，固定在第一填充件靠近内墙的一侧；装饰层的底部与门窗框的顶部抵接，且顶部与过梁的底部抵接，本发明施工工
