Ultrahigh-superposition unilateral formwork reinforcing system and construction method thereof
The invention provides an ultrahigh-superposition unilateral formwork reinforcing system and a construction method thereof. The ultrahigh-superposition unilateral formwork reinforcing system comprises a lower-layer formwork, an upper-layer formwork, first-section formwork supporting frames and second-section formwork supporting frames, wherein the height of the lower-layer formwork is h1; the upper-layer formwork is vertically arranged on the lower-layer formwork, the height of the upper-layer formwork is h2, the pre-inclination value of the upper-layer formwork pre-inclining towards the concrete side is a, the pre-inclination value is the deformation amount of the upper-layer formwork caused by the lateral pressure of concrete to the upper-layer formwork, and the pre-inclination value n of the lower-layer formwork pre-inclining towards the concrete side is n = a.h1/(h1+ h2); the first-section formwork supporting frames are arranged on one side of the lower-layer formwork and fixed to the lower-layer formwork; and the second-section formwork supporting frames are fixed to the first-section formwork supporting frames and fixed to the upper-layer formwork. According to the ultrahigh-superposition unilateral formwork reinforcing system, through the overall design, two sections are superposed and supported during construction, and therefore the lateral pressure of the concrete to the formworks is reduced.
本发明提供了一种超高叠加单侧模板加固体系及其施工方法，包括：下层模板，所述下层模板的高度为h1；上层模板，沿竖向设置于所述下层模板上，所述上层模板的高度为h2，所述上层模板向混凝土侧预倾的预倾值为a，所述预倾值为混凝土对所述上层模板的侧压力导致所述上层模板产生的变形量，所述下层模板向混凝土侧预倾的预倾值n＝a·h1/(h1+h2)；第一段模板支撑架，设于所述下层模板的一侧并与所述下层模板固定；第二段模板支撑架，固定于每个所述第一段模板支撑架上并与所述上层模板固定。本发明超高叠加单侧钢模板支撑体系通过整体设计，在施工时分两段叠加支设，以减小混凝土对模板的侧压力。
