Prefabricated concrete member, connecting piece thereof and manufacturing and construction method
The invention discloses a prefabricated concrete member, a connecting piece thereof and a manufacturing and construction method. The connecting piece comprises an inserting rod, a first sleeve and a clamping piece cylinder, the clamping piece cylinder comprises a clamping piece cylinder main body and a clamping piece arranged on the clamping piece cylinder main body, the clamping piece cylinder main body is provided with a first connecting part used for being connected with a steel bar, the clamping piece cylinder can be fixed to the first sleeve through threads, in the fixed state, the clamping piece is located in the first sleeve, and the insertion end of the inserting rod can be inserted into the first sleeve to be clamped to the clamping piece. The connecting piece has the following advantages that the integrality is good, the inserting rod can be accurately clamped to the clamping piece, the connection is easy, and the failure rate is low; the specification of the clamping piece is not limited by the general size of a tensioning part of the sleeve, so that compared with a mechanical joint in the prior art, the tensile bearing capacity is higher; and the first sleeve and the clamping piece cylinder can be installed in advance in manufacturers during processing in batch, the production time does not need to be occupied, the efficiency of the production stage and the construction stage is improved, and the time cost is saved.
本发明公开了一种预制混凝土构件、其连接件及制作和施工方法，所述连接件包括插杆、第一套筒和夹片筒，所述夹片筒包括夹片筒主体和设置于夹片筒主体上的夹片，所述夹片筒主体上设有用于与钢筋连接的第一连接部，所述夹片筒能通过螺纹与第一套筒相互固定，且在固定状态下，夹片位于第一套筒内，所述插杆的插头能插入第一套筒并与夹片进行卡接。本发明具有以下优点：整体性好，可以使插杆能够准确地卡入夹片，易于连接，失效率低；夹片规格不受套筒张拉部分通用尺寸的限制，从而相较于现有技术中的机械接头的抗拉承载力更高；第一套筒与夹片筒在批量加工时可在厂家提前安装好，无需占用生产时间，提高了生产阶段和施工阶段的效率，节省了时间成本。
