The utility model discloses also under the condition that also reaches the same bearing capacity under the same environment that utilizes, can reduce thick board, reduce ligneous use amount, reach economic effect.
Description
Technical field
The utility model relates to a kind of reinforcement plate member, is specifically related to a kind of quadrature laminated wood that strengthens laminate with perpendicular embedding FRP, is based on CLT(Cross-laminated Technology, i.e. staggered composite technology) reinforcement plate of floor plate.
Background technology
Quadrature laminated wood (CLT) is the abbreviation of cross-laminated timber, design concept originates from Europe, in Europe, some national developments have surpassed 10 years, by staggered superimposed to the plank of certain specification, adopt the techniques such as gummed or stitching, the large scale of producing, what biaxial mechanical capability was superior is solid slab, quadrature laminated wood more and more causes concern at present, as a kind of reinforcing bar and concrete material of realizing non-traditional high-rise wooden construction of replacing, more and more embody its vigor and prospect, quadrature laminated wood is no matter be that plane is interior or plane all has good supporting capacity outward, make it be suitable for highrise building.
Quadrature laminated wood is applicable to how high-rise wooden construction, and CLT plate length of technique can reach 16m now, and width can reach 3m, and thickness can reach 500mm, and wherein length can also be passed through mechanical connection, and the modes such as glue connection are expanded.Two kinds of the superimposed number of plies of alternately laminated layers plate odd several layers and even levels, there is good biaxial mechanical capability, adopt staggered superimposed mode to make stressed more even, there is better mechanical property, can make full use of timber, production and processing is easy, and quadrature laminated wood is by the solid plank of large scale that necessarily relatively the plank of small-sized forms, can be cut into various shapes, not need complicated technological process.
Quadrature laminated wood has been glued at dimensional instability less to a certain extent by quadrature, but be the board member of rift grain laminate gummed relatively entirely, its supporting capacity, bending rigidity declines a little, according to engineering practice, during its floor as house, its thickness will reach 142mm-150mm, and the amount ratio of timber is larger.
Fibre reinforced composites (FRP) have lightweight, high-strength, corrosion-resistant, easy cutting, application property good, save the advantages such as artificial, with FRP, strengthening wooden construction is used widely, not only can improve bearing capacity, rigidity and ductility, also can improve durability and the Creep Characteristics of wooden construction.FRP is when wooden construction uses, and in technology, one of basic theory problem of most critical is whether the adhesive property of FRP and wooden construction can guarantee both co-operation, and timber and FRP glue-line stripping damage are also a kind of mode of failure that FRP strengthens glue laminated wood member.
Utility model content
The utility model is in order to overcome the deficiencies in the prior art, a kind of enhancing quadrature laminated wood with perpendicular embedding FRP laminate is provided, member after enhancing is when improving supporting capacity, also increased ductility, at the identical environment that utilizes, be issued to minimizing thickness of slab object, reasonable more economically, simultaneously special FRP arrangement has been avoided the cementing of the large area wood laminate of traditional F RP enhanced form and FRP plate, effectively reduces and peels off the possibility that causes component damage because of the glue-line between FRP and timber.Make to process convenient, be applicable to suitability for industrialized production.
The technical solution adopted in the utility model is: a kind of unidirectional quadrature laminated wood that strengthens laminate with perpendicular embedding FRP, the laminate that comprises horizontal gummed, the laminate that longitudinally the perpendicular embedding FRP of glued laminated board and band strengthens, above-mentioned each laminate links together by structure glue or nail, and the laminate that the perpendicular embedding FRP of described band strengthens is arranged on the outermost layer that described quadrature laminated wood is subject to tension when curved;
The laminate that the perpendicular embedding FRP of described band strengthens comprises small bore wood saw material and FRP plate, and described FRP plate vertically embeds the plate face of plank, forms the enhancing laminate that many FRP plates and polylith small bore wood saw material spacing glue are combined.
As preferably, described FRP plate material is BFRP(glass fibre reinforced composion), GFRP(basalt fibre reinforcing composite material), CFRP(carbon fibre reinforced composite) in any.
As preferably, the thickness of described FRP plate is 1～4mm.
As preferably, described each laminate thickness is between 16-51mm, and each wooden laminate width of sheet is between 60mm-240mm.
As preferably, described structure glue adopts PUR, EPI or PRF.
As preferably, described quadrature laminated wood is generally odd-level, can be also even level, general 3,5,7 layers the most common, thickness is generally more than 100mm.
As preferably, the mode of described quadrature laminated wood combination is one willfully go up one vertically, or adopts two willfully one to indulge.
The perpendicular embedding FRP of the utility model band strengthens the quadrature laminated wood of laminate, can freely convert laminate reinforcement ratio to meet various enhancing requirements by strengthening thickness and the configuration number of FRP plate in laminate.
The beneficial effects of the utility model are: when containing the quadrature laminated wood raising supporting capacity after perpendicular embedding FRP laminate enhancing by employing, also increased the ductility of member, simultaneously special FRP arrangement effectively reduces and peels off the possibility that causes component damage because of the glue-line between FRP and timber.In the situation that identical utilizing under environment also reach same bearer power, can reduce thickness of slab, reduce the use amount of timber, reach economic effect.
