Crossbow-method-based pre-bending laminated wood-concrete composite beam construction equipment
Pre-bending laminated wood concrete composite beam construction equipment based on crossbow method comprises tensioning bolts arranged at the two ends of a bent laminated wood beam and a longitudinalsupporting beam arranged in the middle of the bent laminated wood beam, a tool anchor is arranged at the top of the longitudinal supporting beam, and a counter-force device is further arranged betweenthe top of the longitudinal supporting beam and the tool anchor. Steel strands are fixed to the tensioning bolts at the two ends of the bent laminated wood beam, and the ends of the two steel strandspenetrate through the tool anchor to be fixed to the tool anchor in a centralized mode. During construction, tensioning bolts are installed at the two ends of the bent laminated wood beam, steel strands are fixed to the two ends of the bent laminated wood beam, one end of the longitudinal supporting beam abuts against the arch crown of the bent laminated wood beam, then the steel strands are pulled to the tool anchor and fixed to the tool anchor, and a counter-force device is arranged between the tool anchor and the top of the longitudinal supporting beam. A counter force is applied to flatten the bent laminated wood beam. First-stage concrete pouring and second-stage concrete pouring are conducted. By the adoption of the construction method, construction of the pre-bent laminated wood concrete composite beam can be conducted smoothly.
一种基于弩弓法的预弯胶合木‑混凝土组合梁施工设备，包括设置在弯曲胶合木梁两端的张拉螺栓，以及设置在弯曲胶合木梁中部的纵向支撑梁，纵向支撑梁顶部设置有工具锚，在纵向支撑梁顶部与工具锚之间还设置反力装置，在弯曲胶合木梁两端的张拉螺栓上固定钢绞线，两根钢绞线的端部穿过工具锚集中固定在工具锚上。施工时，在弯曲的胶合木梁的两端安装张拉螺栓，将钢绞线固定在弯曲的胶合木梁两端，将纵向支撑梁的一端顶住弯曲的胶合木梁的拱顶，然后将钢绞线拉向工具锚并固定在工具锚上，工具锚与纵向支撑梁顶部之间有反力装置，施加反力拉平弯曲胶合木梁。进行一期混凝土浇筑和二期混凝土浇筑。采用本发明能够顺利进行预弯胶合木‑混凝土组合梁的施工。
