The invention relates to a truss structure, an escalator and an installation method of the escalator. The truss structure comprises a lower chord piece, an upper chord piece, a reinforcing piece and a connecting piece, the lower chord piece is T-shaped steel, and the lower chord piece is used for being installed on a building structure; the upper chord piece and the lower chord piece are arranged in parallel; the reinforcing piece is mounted on the upper chord piece; the two ends, away from each other, of the connecting piece are connected with the upper chord piece and the lower chord piece. The installation reinforcer ensures that the installation of other parts of the escalator is not affected while the structural strength of the upper chord is ensured, and the width of the truss structure is not increased for enhancing the structural strength. The lower chord piece is T-shaped steel, so that the overall bending resistance of the truss structure is enhanced. The width and the depth of the truss structure are not increased and the size of a pit for mounting the truss structure is not increased under a large-span and middle-support-free scene of the truss structure. And other parts for supporting and enhancing the structural strength of the lower chord piece are avoided, so that the weight and the construction cost of the truss structure are reduced.
本申请涉及一种桁架结构、扶梯及其安装方法。桁架结构包括下弦件、上弦件、加强件和连接件,下弦件为T型钢,下弦件用于安装在建筑结构上;上弦件与下弦件平行设置;加强件安装在上弦件上;连接件相远离的两端部分别连接上弦件和下弦件。安装加强件在保证上弦件结构强度的同时也确保了不会影响扶梯其他部件的安装,也不会为了增强结构强度而增加桁架结构的宽度。下弦件为T型钢增强了桁架结构整体的抗弯性能。保证了桁架结构在大跨距无中间支撑场景下,桁架结构的宽度和深度不会增加,安装桁架结构的底坑尺寸不会增大。避免了设置其他支撑和加强下弦件结构强度的部件,进而降低了桁架结构的重量及建造成本。
