The assembled floor of production.
Background technique
With the development and popularization of the engineered woods such as glued laminated timber, wood-based structural panel and structural composite lumber, especially
The appearance and application of orthogonal laminated wood (Cross-Laminated Timber, abbreviation CLT), timber buildings develop center of gravity gradually
It is transferred on heavy timber construction by light-duty wooden, the interior spatial structure of timber buildings is more diversified.However timber
Itself has the characteristics that elasticity modulus is small, deflection deformation is big so that when using the floorboard and roof boarding of CLT production needs compared with
The beam column component of multi-quantity is supported, to reduce the effective use space of inside configuration, to hall, meeting room, banquet hall etc.
Internal volume requirement Shao Liang, there are certain difficulty for the design without column.
For using in the board member of post stretching tensioning, the both ends of board member not only local compression, also around compressive region
There is also tensile stresses, and stress condition is complicated, be easy to cause bending deformation, are unfavorable for wooden board member.And wood
For material under the influence of by long-range circumstances factor, edge loss is serious, or even cracking, more importantly the wooden timber is in imposed load
Creep can be generated under long term, so that the boundary condition of unbonded prestressing tendon changes, reduce unbonded prestressing tendon
Middle prestressing force.
FRP is used to combine in existing scheme with CLT to promote bearing capacity, such as Chinese Patent No.
" 201310483522.7 " number disclose a kind of " a kind of unidirectional orthogonal laminated wood that band FRP longitudinally enhances ", by using containing
The orthogonal laminated wood of band FRP also increases the ductility of component while improving bearing capacity, under identical utilization environment
Reach and reduce plate thickness purpose, but FRP material is limited to the overall stiffness promotion of CLT plate, cannot effectively improve bearing capacity.
For above-mentioned deficiency, the utility model lies in that mentioning a kind of assembled made with CLT plate and unbonded prestressing tendon
Floor, it is intended to solve the problem of using span when a small amount of beam column component support floorboard and roof boarding and Lack of support
