Bridge prestress tensioning device and using method
The invention provides a bridge prestress tensioning device and a using method, and belongs to the technical field of bridge construction equipment.The bridge prestress tensioning device comprises a bridge body and a pre-buried channel formed in the bridge body, anchor bearing plates are fixedly installed on the portions, located on the two sides of the pre-buried channel, of the left end face and the right end face of the bridge body, and spiral bars are fixedly installed on the inner side walls of the anchor bearing plates; a corrugated channel pipe is fixedly installed between the anchor bearing plates on the left side and the right side, a steel rope strand is embedded in an inner cavity of the corrugated channel pipe, an anchorage device plate is clamped to the outer side wall of each anchor bearing plate, an anchorage device clamping piece is installed in an inner cavity of each anchorage device plate in a clamped mode, and a cooling mechanism is arranged in an inner cavity of each anchorage device clamping piece. According to the steel rope tensioning device, through the arrangement of the tensioning mechanism, the function of tensioning the steel rope strand embedded in the corrugated channel pipe is achieved, through the arrangement of the cooling mechanism, cooling and heat dissipation can be conducted on the steel rope strand while tensioning is conducted, it is guaranteed that the steel rope strand has good toughness at the normal working temperature, and stable implementation of the tensioning process is guaranteed.
本发明提供了一种桥梁预应力张拉装置及使用方法，属于桥梁施工设备技术领域，包括桥梁体，以及开设在桥梁体上的预埋道，所述桥梁体的左右端面位于预埋道的两侧均固定安装有锚垫板，所述锚垫板的内侧壁上固定安装有螺旋筋，左右两侧的所述锚垫板之间固定安装有波纹通道管，所述波纹通道管的内腔预埋有钢绳股，所述锚垫板的外侧壁上卡接有锚具板，所述锚具板的内腔卡合安装有锚具夹片，所述锚具夹片的内腔设置有冷却机构。该发明通过张拉机构的设置，实现了向波纹通道管内预埋的钢绳股进行张拉的功能，通过冷却机构的设置，能够在张拉的同时对钢绳股进行冷却散热，保证了其在正常工作温度下具有良好的韧性，保证了张拉过程的稳定实施。
