2-1200 g/m
2The four-axial glass fiber forms by laminated being solidified into of vinylite, planar isotropism.
The through hole that described gummed wooden frame 3 ends are used for installing connecting bolt glueds joint GFRP reinforced pipe 6, installs on the gummed pin that gluing has GFRP reinforced pipe 6 in the hole of connecting bolt of node region of metal connecting piece.
It is 1.2-2.8mm that described GFRP strengthens muscle pipe 6 thickness, by two to four layers of 800g/m
2-1200 g/m
2The four-axial glass fiber forms by laminated being solidified into of vinylite, vertically isotropism.Through actual measurement, its modulus of elasticity is 8730MPa.Test specimen is integral one-step molding under atmospheric pressure, guarantees the no delamination of bonding fully between panel and the core.
Beneficial effect of the present invention:
The present invention can improve the anisotropy of contact area timber, the concentrated distribution that slows down stress;
1. the present invention changes over the cleavage fracture of the failure mode-timber of the brittle fracture of connected node the bearing failure of ductile failure mode-keyhole;
2. the present invention is conducive to improve the supporting capacity of laminated wood bolt connected node;
3. the present invention can reduce the end distance of connected node, middle distance is the size of connector;
4. the present invention can reduce sectional dimension and the deadweight of supporting member;
5. the present invention can embody the seismic design theory (or requirement) of strong shear capacity and weak bending capacity, the strong strong anchoring of node;
6. the present invention can reduce cost and construction cost (20000 yuan/m of large scale glue laminated wood member market price
3).
7. the present invention provides reliable connection for the Load Transfer of striding qlue timber structurer greatly, for structural safety is reliably laid a good foundation.It not only can be used for enhancing and the reinforcing of traditional old wooden construction, also can be used for the lifting of the structural performance of wood structures.
