Large-span prestressed concrete roof structure and using method thereof
The invention discloses a large-span prestressed concrete roof structure and a using method thereof.The large-span prestressed concrete roof structure comprises mounting columns symmetrically arranged on the left side and the right side in rows, the left end of a large-span concrete roof is mounted on the mounting column on the left side, and the right end of the concrete roof is mounted on the mounting column on the right side; the large-span prestressed concrete roof structure is provided with a plurality of prestressed concrete core columns, the prestressed concrete core columns are arranged in parallel front and back, the left ends of the prestressed concrete core columns are fixed to the mounting column on the left side, and the right ends of the prestressed concrete core columns are fixed to the mounting column on the right side. The middle section of the prestressed concrete core column is located in the concrete roof and fixed with the concrete roof into a whole, and a prestressed steel strand is poured in the prestressed concrete core column. When the concrete roof is poured, secondary maintenance is not needed, and only if the poured concrete is solidified to reach the preset strength, the construction time can be greatly saved.
本发明公开了大跨度预应力混凝土屋顶结构及其使用方法，其中结构包括左侧和右侧成排对称设置的安装柱，大跨度混凝土屋顶的左端安装在左侧的安装柱上，混凝土屋顶的右端安装在右侧的安装柱上，大跨度预应力混凝土屋顶结构设有若干个预应力混凝土核心柱，预应力混凝土核心柱前后平行设置，预应力混凝土核心柱的左端固定在左侧的安装柱上，预应力混凝土核心柱的右端固定在右侧的安装柱上，预应力混凝土核心柱中段位于混凝土屋顶内，并与混凝土屋顶固定为一体，预应力混凝土核心柱内浇筑有预应力钢绞线。本发明在浇筑混凝土屋顶时不需要进行二次养护，只要等浇筑的混凝土凝固达到预定强度即可，能极大的节约施工时间。
