Prestressed anchorage device for highway bridge construction
The invention discloses a pre-stressed anchorage device for highway bridge construction, which comprises a fixed anchor plate, a plurality of steel stranded wires are inserted in the fixed anchor plate, a plurality of grouting holes are formed in the edge of the fixed anchor plate, a threaded sleeve is arranged on one side of the fixed anchor plate, an annular disc is arranged on the other side of the fixed anchor plate, and the threaded sleeve is sleeved with the annular disc. A plurality of clamping plates are arranged at the end, away from the fixed anchor plate, of the threaded sleeve, the surfaces of the clamping plates are sleeved with spiral bars, one ends of the spiral bars are fixedly connected with the threaded sleeve, and the steel stranded wires penetrate through the space between the threaded sleeve and the clamping plates; a plurality of bayonets are formed in the edge of the annular disc. The directions of pressure on the two sides of the steel stranded wire are opposite, pressure is applied to the steel stranded wire from the side edge, the steel stranded wire can be correspondingly and transversely twisted and deformed, the twisted and deformed steel stranded wire can be better fixedly connected with the fixed anchor plate, and therefore the stability of the whole structure of the steel stranded wire is effectively guaranteed.
本发明公开了一种公路桥梁施工用预应力锚具，包括固定锚板，所述固定锚板上穿插有多个钢绞丝，所述固定锚板的边缘开设有多个注浆孔，所述固定锚板的一侧设置有螺纹套筒，所述固定锚板的另一侧设置有环形盘，所述螺纹套筒远离固定锚板的一端设置有多个夹板，所述夹板的表面上套接有螺旋筋，所述螺旋筋的一端与螺纹套筒固定连接，多个所述钢绞丝从螺纹套筒、夹板之间穿过；所述环形盘的边缘开设有多个卡口。本发明通过对钢绞丝两侧的压力方向相反，从侧边对钢绞丝施加压力，则会对钢绞丝造成相应的横向扭曲变形，扭曲变形后的钢绞丝能够更好的使其与固定锚板固定连接到一起，从而有效的保证其整体结构的稳定。
