Tensioning frame
The invention relates to the technical field of precast beam construction, in particular to a tensioning frame which comprises a rear anchor beam, a counter-force column, a cable-stayed belt, an upper tension-bearing steel box beam and a lower tension-bearing steel box beam, the upper tension-bearing steel box beam and the lower tension-bearing steel box beam are connected to the upper end and the lower end of the counter-force column through jacks respectively, one end of the cable-stayed belt is connected with the counter-force column, and the other end of the cable-stayed belt is connected with the rear anchor beam. The other end of the connecting rod is connected with the rear anchor beam which is arranged on a certain supporting face in an inclined mode. The rear anchor beam, the counter-force column and the inclined pull belt are pressed components when the steel strand is in a pulled state, so that the components meet the requirement of pressed bearing capacity, and when the steel strand is in a tightened state, the rear anchor beam, the counter-force column, the inclined pull belt, the bearing steel box beam and the pedestal jointly participate in stress so as to resist overturning bending moment brought by tensioning force. Therefore, the problems of cracking, distortion, deformation and the like after the precast beam is tensioned are effectively avoided, and the construction quality is guaranteed.
本发明涉及预制梁施工技术领域，具体而言，涉及一种张拉架，包括后锚梁、反力柱、斜拉带、上承拉钢箱梁和下承拉钢箱梁，上承拉钢箱梁和下承拉钢箱梁分别通过千斤顶连接于反力柱的上下两端，斜拉带的一端与反力柱连接，另一端与后锚梁连接，后锚梁斜向设置于某支撑面。后锚梁、反力柱和斜拉带在钢绞线受拉状态下为受压构件，因此构件满足受压承载力的要求，在钢绞线处于绷紧状态下，后锚梁、反力柱、斜拉带和承拉钢箱梁与台座共同参与受力，以抵抗张拉力带来的倾覆弯矩。从而有效避免了预制梁张拉后的开裂、扭曲、变形等问题，保证了施工质量。
