Gate-type pier cross beam construction method and formwork
The invention discloses a gate-type pier cross beam construction method and a formwork. The gate-type pier cross beam construction method comprises the steps that a bearing platform is constructed; pier column construction is performed; a bottom die is constructed, specifically, the steel pipe column is welded to the bearing platform pre-embedded steel plate and the pier column pre-embedded steel plate; I-shaped steel beams are welded to the steel pipe columns; a plurality of I-steel longitudinal beams are welded and laid on the I-steel cross beams; a plurality of I-shaped steel distribution beams are welded and laid on the I-shaped steel longitudinal beams; vertical rods are installed on the I-shaped steel distribution beams, the two vertical rods are connected through transverse rods to form a rectangular frame, and inclined supporting rods are installed on the diagonal lines of the rectangular frame; leveling I-shaped steel is laid on the vertical rods for leveling; a bottom die is laid on the leveling I-shaped steel; loading and unloading are carried out according to 0-80%-100%-110%-100%-80%-0 of the total load weight, settlement data are obtained, and the bottom die is adjusted to the designed elevation; cross beam reinforcing steel bars and prestressed pipelines are installed; a side formwork is constructed; pouring and molding are performed; and pre-stress engineering is performed. The single-line beam and the gate-type pier are constructed at the same time, and the construction efficiency is high.
本发明公开了一种门式墩横梁施工方法及模架，门式墩横梁施工方法包括步骤：承台施工；墩柱施工；底模施工：将钢管柱同承台预埋钢板、墩柱预埋钢板焊接；于钢管柱焊接工字钢横梁；于工字钢横梁焊接铺设多个工字钢纵梁；于工字钢纵梁焊接铺设多个工字钢分配梁；于工字钢分配梁安装立杆，横杆将两个立杆连接形成矩形框架，于矩形框架的对角线安装斜撑杆；于立杆铺设调平工字钢以调平；于所述调平工字钢铺设底模；按照荷载总重的0→80%→100%→110%→100%→80%→0加载及卸载，并获取沉降数据并调整底模至设计标高；横梁钢筋和预应力管道安装；侧模施工；浇筑成型；预应力工程。本发明实现单线梁和门式墩同时施工，施工效率高。
