In-vivo string-type CFRP-metal combined structure device and in-vivo string-type CFRP-metal combined structure method
The invention discloses an in-vivo string-tensioning CFRP-metal composite structure device and method, the device comprises an I-beam and two groups of prestress applying units, the two groups of prestress applying units can be symmetrically arranged between wing plates on two sides of the I-beam, and the two groups of prestress applying units comprise two groups of oblique anchoring assemblies and two groups of prestress applying assemblies; the two sets of oblique anchoring assemblies are connected with the two ends of the CFRP sheet in a matched mode correspondingly, the two sets of prestress applying assemblies are symmetrically arranged relative to the CFRP sheet, and prestress is applied to the CFRP sheet by rotating the prestress applying assemblies. According to the scheme, the CFRP sheet is arranged in the I-shaped steel body, so that the occupation of a clear height space outside the I-shaped steel is avoided; meanwhile, prestress can be effectively applied through the rotary telescopic push rod, and the size of the prestress can be controlled and adjusted through the number of rotation circles; in addition, an inclined anchoring device and a CFRP steering block are designed, the CFRP sheet can be bent gently, and the influence on the strength of the CFRP sheet due to the fact that the bending angle of the CFRP sheet is too large is reduced.
本发明公开了一种体内张弦式CFRP‑金属组合结构装置及方法，包括工字梁，两组预应力施加单元，两组预应力施加单元可对称设置于工字梁两侧的翼板之间，两组预应力施加单元包括两组斜形锚固组件，两组预应力施加组件，两组斜形锚固组件分别与CFRP片材的两端进行配合连接，两组预应力施加组件对称且相对CFRP片材设置，通过转动预应力施加组件来对CFRP片材进行预应力的施加。本方案通过将CFRP片材设置在工字钢体内，避免了对工字钢外净高空间的占用；同时，通过旋转式伸缩推杆可有效施加预应力，并可以通过旋转周数对预应力大小进行控制及调节；另外，本发明设计斜形锚固装置与CFRP转向块，可平缓弯折CFRP片材，降低CFRP片材弯折角度过大对CFRP片材强度的影响。
