The invention relates to a concrete terrace expansion joint slotting method and an expansion joint reinforcing piece, and belongs to the technical field of building accessories. The device is characterized by comprising two fixing frames, a connecting rib, a force transmission pin and a force transmission pin sleeve matched with the force transmission pin, wherein each fixing frame is composed of an upper reinforcing steel bar, a lower reinforcing steel bar and a plurality of stirrups arranged between the upper reinforcing steel bar and the lower reinforcing steel bar at intervals; one end of each force transmission pin is sleeved with a force transmission pin sleeve and arranged at the upper end of the fixing frame at intervals; the two fixing frames are oppositely arranged to be in a splayed shape, the upper steel bars are connected through a plurality of connecting bars arranged at intervals, and the two ends of the force transmission pin are fixed to the upper steel bars through opposite stirrups on the two fixing frames respectively. According to the construction method, construction is simple, arrangement can be completed by a single worker, the requirement for the cutting depth of the concrete terrace is low, the requirement for construction equipment is lowered, the integrity of the terrace on the two sides of the expansion joint can be enhanced after the construction joint is slotted, and oblique cracks and height difference generated by concrete on the two sides of the slotted position are avoided.
本发明涉及一种混凝土地坪伸缩缝开缝方法及伸缩缝补强件，属于建筑配件技术领域。其特征在于：包括两个固定架、连接筋、传力销和与传力销配套的传力销套，其中固定架由分别上部钢筋、下部钢筋和多个间隔布置在上下钢筋之间的箍筋组成；传力销的一端套有传力销套，并间隔设置在固定架上端；两个固定架相对设置成八字形，上部钢筋之间通过多个间隔设置的连接筋连接，传力销的两端被两个固定架上相对的箍筋分别固定在其上部钢筋上。本发明施工简单，单个工人即可完成布置，对混凝土地坪的切割深度要求低，降低了对施工机具的要求，并且在施工缝开缝后能加强伸缩缝两边地坪的整体性，避免开缝处两侧混凝土产生斜向裂纹和高差。
