Construction method of thin-wall concrete hollow floor

The invention discloses a construction method of a thin-wall concrete hollow floor. The construction method comprises the following steps of (S1) erecting a scaffold as a formwork supporting frame, and laying bottom formworks, wherein the outer edge spacing of the bottom formworks is 18 to 25 cm; and (S2) binding floor bottom steel bars, wherein a plurality of vertical bars are bound on the upper surfaces of the bottom steel bars according to design requirements when the bottom steel bars are bound, one to two vertical bars are arranged between every two core molds, one to two vertical bars are arranged between the core molds and the formworks, and the bottom steel bars are supported and cushioned on the bottom formworks through cushion blocks. According to the construction method, the core molds can be effectively prevented from floating upwards. 本发明公开了一种薄壁混凝土空心楼盖施工方法，包括以下步骤：S1、搭设脚手架作为支模架，铺设底层模板，底层模板的外楞间距为18～25cm；S2、绑扎楼板底层钢筋，绑扎底层钢筋时，按设计要求在底层钢筋的上表面绑扎若干竖筋，使每两个芯模之间均具有1～2个竖筋、芯模与模板之间具有1～2个竖筋，底层钢筋通过垫块支垫于底层模板上。本发明能
