Square concrete funnel formwork supporting structure and construction method
The invention provides a square concrete funnel formwork supporting structure and a construction method. The square concrete funnel formwork supporting structure comprises an upper formwork, a lower formwork, an upper secondary ridge, a lower secondary ridge, opposite-pull screws, an upper main ridge and lower main ridges; each lower main ridge is composed of two trusses, each truss is of a plane frame structure formed by welding and connecting an upper chord member, a lower chord member and a web member, the upper chord members are steel pipes with the same specification as the upper main ridge, and the upper chord members are welded and connected between the two trusses through connecting rods; and when the formworks are supported, the multiple lower main ridges are arranged at the bottom of the lower formwork and the bottom of the lower secondary ridge side by side, the length direction of the lower main ridges is perpendicular to the inclined wall of a funnel, the upper chord members of every two adjacent lower main ridges are connected through a mountain-shaped clamp and connected with the upper main ridge through the opposite-pull screws, and supporting frames are erected at the bottoms of the lower main ridges. According to the square concrete funnel formwork supporting structure and the construction method, the rigidity of the lower formwork supporting structure on the inclined wall of the funnel is improved, the strength of the lower formwork is improved, the lower formwork is prevented from deforming, and the funnel concrete construction quality is guaranteed.
一种方形混凝土漏斗模板支设结构及施工方法，包括上模板、下模板、上次楞、下次楞、对拉螺杆、上主楞、下主楞，所述下主楞是由两个桁架构成，所述桁架是由上弦杆、下弦杆和腹杆焊接连接而成的平面框架结构，所述上弦杆是与上主楞相同规格的钢管，两个所述桁架之间通过连接杆将上弦杆焊接连接；支设模板时，若干个下主楞并列设置在下模板和下次楞底部，下主楞长度方向与漏斗斜壁垂直，相邻两个下主楞的上弦杆通过山形卡连接并通过对拉螺杆与上主楞连接，所述下主楞底部架设支撑架。本发明一种方形混凝土漏斗模板支设结构及施工方法，通过增加漏斗斜壁下模板支设结构的刚度，增加下模板强度，防止下模板变形，保证漏斗混凝土施工质量。
