Segmental assembled prestressed steel-wood combined truss rod piece and mounting method thereof
The invention relates to a segmental assembled prestressed steel-wood combined truss rod piece. The segmental assembled prestressed steel-wood combined truss rod piece comprises a plurality of wood rod piece segments, prestressed threaded steel bars, end shear-resistant anchoring iron nails and end steel connecting pieces, wherein flanges and notches are respectively arranged on the head and tail ends of the wood rod piece segments, and through round holes are formed in the middle of the wood rod piece segments; the prestressed threaded steel bars sequentially penetrate through the wood rod piece segments, and the adjacent wood rod piece segments are tightly buckled through the flanges and the notches to form a long-strip-shaped rod piece; through holes are formed in the middle of the end steel connecting pieces, the two ends of the long-strip-shaped rod piece respectively penetrate through the end steel connecting pieces, and the end steel connecting pieces make contact with the wood rod piece segments on the head and tail ends correspondingly and are locked through end anchoring nuts which are matched with the prestressed threaded steel bars; and the end steel connecting pieces are fixedly connected with the wood rod piece segments through the end shear-resistant anchoring iron nails. The segmental assembled prestressed steel-wood combined truss rod piece has the advantages of large section rigidity and good mechanical properties and can bear tension and pressure at the same time, and zero carbon emission of the whole component can be achieved.
本发明涉及一种节段拼装预应力钢木组合桁架杆件，包括若干木杆件节段、预应力螺纹钢筋、端部抗剪锚固铁钉和端部钢连接件；木杆件节段的首尾两端分别设置凸缘和槽口，中部设置中通圆孔；各木杆件节段依次穿入预应力螺纹钢筋，相邻木杆件节段之间通过凸缘和槽口实现紧密扣合，形成一个长条形杆件；端部钢连接件中部设有通孔，长条形杆件两端分别穿设端部钢连接件，端部钢连接件分别与首尾两端的木杆件节段接触，并通过与预应力螺纹钢筋适配的端部锚固螺母实现锁固；端部钢连接件与木杆件节段之间通过端部抗剪锚固铁钉固定连接。本发明钢木组合桁架杆件截面刚度较大，可同时承受拉力和压力，具有更佳的力学性能，还能实现整体构件的零碳排。
