Fabricated concrete tree-shaped support and construction method thereof
The invention discloses an assembly type concrete tree-shaped support and a construction method thereof. The support comprises a cast-in-place column section, and a grouting sleeve is pre-embedded in the top face of the cast-in-place column section; grouting holes are formed in the bottoms of the prefabricated columns; a prefabricated hole is formed in the middle of the prefabricated inclined column, and a spring cushion is arranged on the top surface of the prefabricated inclined column; the middle steel joint is connected between the prefabricated column and the prefabricated inclined column, a hole is formed in the middle of the supporting face, a first end anchor disc of the steel strand is fixed in the hole of the supporting face, the steel strand penetrates out of the hole of the supporting face and a prefabricated hole of the prefabricated inclined column, and the middle steel joint, the prefabricated column and the prefabricated inclined column are integrally formed in a pouring mode; preformed holes are formed in the middles of the crotch prefabricated splicing sections, anchor disc reserved clamping positions are arranged at the ends of the crotch prefabricated splicing sections, anchor discs at the second ends, penetrating out of the preformed holes, of the steel strands are locked and fixed in the anchor disc reserved clamping positions, and grouting holes are formed in the ends, close to the prefabricated inclined columns, of the sections. According to the method, in large-scale repeated tree support construction, construction can be fast and convenient, and use of large-scale manpower and material resources on site is reduced.
本发明公开了一种装配式混凝土树状支撑及其施工方法，支撑包括：现浇柱段，顶面预埋有灌浆套筒；预制柱，底部设置注浆孔；预制斜柱，中部设置预制孔，预制斜柱顶面设置有弹簧垫；中部钢制节点，连接于预制柱与预制斜柱之间，支撑面中部开孔，钢绞线第一端锚盘固定在支撑面开孔中，钢绞线从支撑面开孔以及预制斜柱的预制孔中穿出，中部钢制节点与预制柱、预制斜柱一体浇筑成型；树杈预制拼接节段，中部设置预留孔，端部设置有锚盘预留卡位，钢绞线穿出预留孔的第二端上的锚盘锁紧固定在锚盘预留卡位中，节段在靠近预制斜柱的一端上设置有注浆孔。本发明在大规模树状支撑重复建设中，能够实现施工的快速化、便捷化，减少现场大规模人力物力的使用。
