Steel-wood combined roof truss carbon fiber reinforcement construction method
The invention provides a steel-wood combined roof truss carbon fiber reinforcement construction method which comprises the following steps: S1, firstly removing greasy dirt and floating dust on the surface of a wood structure, repairing an uneven part, and carrying out prime coat according to the requirements of a selected product; s2, processing a pressed upper chord of the combined roof truss by adopting a cross section enlarging reinforcing method; the method comprises the following steps of: arranging top-layer square timber at the top of a pressed upper chord of the combined roof truss, bonding the top-layer square timber and the top of a wood structure through glue injection and bolts, and winding carbon fiber surrounding hoops at two ends of each internode to ensure reliable connection; s3, longitudinal purlines are arranged above the top-layer square timbers, and the metal roof panels are connected with the purlines; S4, full-length tensile steel bars are arranged below the timber structure, and the compression supporting rods of the combined roof truss are connected with the lower chord tensile steel bars through connecting pieces; and S5, the first log with the insufficient axial bearing capacity is treated through a carbon fiber rib reinforcing method. The wood structure building can be reinforced, the effect is good after reinforcing construction, and the service life of the reinforcing structure is long.
本发明提出一种钢木组合屋架碳纤维加固施工方法，包括如下步骤：S1：先清除木结构表面的油污、浮尘，对不平整部位进行修复处理，按选用产品的要求进行底涂；S2：对组合屋架受压上弦杆采用加大截面加固法进行处理；即对组合屋架受压上弦杆顶部设置顶层方木，顶层方木与木结构顶部之间通过注胶粘接和螺栓，并在每个节间两端缠绕碳纤维围箍以保证连接可靠；S3：在顶层方木上方设置纵向檩条，金属屋面板与檩条连接，S4：在木结构下方设置通长受拉钢筋，组合屋架的受压撑杆通过连接件与下弦受拉钢筋连接；S5：对轴向承载力不足的第一圆木采用碳纤维筋加固法进行处理。其能够对木结构建筑进行加固，加固施工后效果好，加固结构使用寿命长。
