External prestressing combined reinforcing method
The invention belongs to the technical field of prestress steel strand tensioning and fixing, and particularly relates to an external prestress combined type reinforcing method which comprises the following steps that S10, a clamp is fixed to a prestress tensioning device, S20, a steel strand is placed in the clamp, and prestress stretching is conducted; s30, the fixator is fixed to the component body to be reinforced; s40, the other end of the clamp is fixed to the fixator, so that the prestress tensioning device is fixed to the fixator; s50, after fixing is completed, prestress stretching adjustment is conducted through a prestress tensioning device; and S60, after adjustment, the prestress tensioning device is taken down, and reinforcement is completed. According to the method, the steel strand is fixed through the clamp, then pre-tightening force stretching is conducted outside the body, then the steel strand is fixed to the fixator through the clamp, at the moment, an operator can adjust the pre-stress stretching degree, and finally reinforcement can be completed by taking down the pre-stress stretching device. Compared with an existing scheme, the method has the advantages that steps are simplified, and time is saved.
本发明属于预应力钢绞线张拉固定技术领域，具体涉及一种体外预应力组合式加固方法，包括以下步骤：步骤S10：将夹具固定在预应力张拉装置上，步骤S20：将钢绞线放置在夹具内，进行预应力拉伸；步骤S30：将固定器固定在待加固构件体上；步骤S40：将夹具另一端固定在固定器上，使得预应力张拉装置固定在固定器上；步骤S50：固定好后通过预应力张拉装置进行预应力拉伸调整；步骤S60：调整好后将预应力张拉装置取下，完成加固。本方法先通过夹具固定好钢绞线，然后在体外进行预紧力拉伸好，再通过夹具固定到固定器上，这时操作者可以调节预应力拉伸程度，最后取下预应力张拉装置即可完成加固。相比于现有的方案，本方法简化了步骤，节省了时间。
