Ultra-high performance concrete truss concrete rib
The invention relates to an ultra-high performance concrete truss concrete rib, relates to the technical field of buildings, and aims to improve the rigidity of a truss concrete rib precast slab and solve the problems that the stability is poor when a truss rib is reversely buckled for concrete pouring, and the concrete rib is easy to crack after being poured. The structure comprises UHPC concrete ribs and truss ribs, wherein the truss ribs comprise an upper chord rib, a plurality of web member ribs and two lower chord ribs; a supporting piece is arranged on the outer wall of the upper chord rib and comprises two supporting ribs and an abutting rib, one ends of the two supporting ribs abut against each other to form a clamping opening for clamping the upper chord rib, and the abutting rib is arranged at the end, away from the other supporting rib, of the corresponding supporting rib. The truss rib UHPC concrete rib structure for the laminated slab has the advantage of being large in rigidity, the rigidity of the whole slab can be improved when the truss rib UHPC concrete rib structure is applied to a prefabricated slab, the production, transportation and installation efficiency is improved, and meanwhile the truss rib internal structure has the effects of improving the stability when the truss rib is inversely buckled and improving the forming quality and the convenience degree when concrete is poured into the truss rib.
本申请涉及一种超高性能混凝土桁架砼肋，涉及建筑技术领域，为了提高桁架砼肋预制板刚度，解决桁架筋倒扣进行混凝土浇筑时稳定性差，砼肋浇筑完成后易开裂的问题。其包括UHPC砼肋和桁架筋，桁架筋包括上弦筋、若干腹杆筋和两条下弦筋；上弦筋外壁设置有支撑件，支撑件包括两条支撑筋和抵紧筋，两条支撑筋一端相抵并形成可供上弦筋卡接的卡接口，抵紧筋设置于相应的支撑筋背离另一支撑筋的一端。本申请的叠合板用桁架筋UHPC砼肋构造具有刚度大的优点，应用于预制板上可提高整体板型的刚度，提高生产、运输及安装效率，同时桁架筋内部构造具有提高桁架筋倒扣时的稳定性，提高桁架筋浇筑混凝土时的成型质量和便捷程度的效果。
