Method for reinforcing wood beam through embedded shape memory alloy stranded wires
The invention relates to a method for reinforcing a wood beam through embedded shape memory alloy stranded wires in the field of civil engineering. In brief, the method includes the following steps offorming beam grooves in the surfaces of transverse lines of the wood beam through a grooving machine, wherein the beam grooves extend along the overall length of the wood beam; putting the shape memory alloy stranded wires into the beam grooves, and completely fixing the shape memory alloy stranded wires into the beam grooves through fixing assemblies; and injecting a structural adhesive into thebeam grooves, and then performing curing for a certain period of time so that the shape memory alloy stranded wires can be closely attached to the wood beam. On the premise of a sufficient number ofthe shape memory alloy stranded wires, by means of the method, the flexural capacity and deformability of the wood beam can be improved to a certain extent. Meanwhile, by means of the method, the influences of a traditional carbon fiber sheet attachment reinforcing method on the appearance of the beam can be reduced. In addition, by means of the method, the unrecoverable deformation of the wood beam under the action of a vertical earthquake can be reduced to a certain extent, the self-reset performance of the wood beam is improved, and therefore the after-earthquake maintenance cost and time of the wood structure are reduced.
本发明涉及土木工程领域内的一种内嵌形状记忆合金绞线加固木梁的方法,简而言之,包括如下步骤:使用开槽机在木梁横纹表面开设梁槽,梁槽沿木梁的全长布置延伸;将形状记忆合金绞线置入梁槽内,并用固定组件将形状记忆合金绞线完全地固定在梁槽内;在梁槽内注入结构胶,然后进行一段时间的养护,以使形状记忆合金绞线紧密粘接木梁。在形状记忆合金绞线数量足够的前提下,本发明可在一定程度上提升木梁的抗弯承载力和变形能力。同时,本发明可降低传统粘贴碳纤维布加固法对梁外观造成的影响。此外,本发明可在一定程度上降低木梁在竖向地震作用下产生的不可恢复变形,提升木梁的自复位性能,从而降低木结构震后维修成本和时间。
