Prestress reinforced wooden roof truss
The invention discloses a prestress reinforcing method for a building wooden roof truss, relates to the technical field of reinforcing engineering of traditional wooden roof trusses, and aims to solve the problems that in the prior art, at least one of historical vicisgiss and high engineering cost of a building cannot be reserved during reinforcing of a wooden roof. The method comprises the steps that one end of a lower chord prestressed pull rod is fixedly connected with one end of a lower chord, and the other end of the lower chord prestressed pull rod is fixedly connected with the other end of the lower chord; fixedly connecting the upper ends of the vertical web prestressed pull rods with the upper chord members, and fixedly connecting the lower ends of the vertical web prestressed pull rods with the lower chord members; prestress is applied to the lower chord prestress pull rods and the vertical web prestress pull rods respectively, the lower chord is subjected to prestress reinforcement through the lower chord prestress pull rods, and the vertical web members are subjected to prestress reinforcement through the vertical web prestress pull rods, so that the tension borne by the lower chord and the vertical web members is reduced. The method can be used for reinforcing the building wooden roof truss.
本发明公开了一种建筑木屋架的预应力加固方法，涉及传统木屋架的加固工程技术领域，用以解决现有技术中木屋顶加固无法保留建筑的历史沧桑感、工程造价高中的至少一个的问题。该方法包括将下弦预应力拉杆的一端与下弦杆的一端固定连接，将下弦预应力拉杆的另一端与下弦杆的另一端固定连接；将竖腹预应力拉杆的上端与上弦杆固定连接，将竖腹预应力拉杆的下端与下弦杆固定连接；分别对下弦预应力拉杆和竖腹预应力拉杆施加预应力，通过下弦预应力拉杆对下弦杆进行预应力加固，通过竖腹预应力拉杆对竖腹杆进行预应力加固，使得下弦杆和竖腹杆所受拉力减小。本发明可用于建筑木屋架的加固。
