Abstract
The utility model discloses unidirectional cross-laminated timber enhanced by longitudinal strip FRP (Fiber Reinforce Plastic).. The cross-laminated timber comprises transversely-laminated laminates, longitudinally-laminated laminates and a longitudinal strip FRP single plate, wherein all the laminates are connected together by structural adhesives or nails; the longitudinal strip FRP single plate is arranged on the tensioned outermost layer of the cross-laminated timber in bending; the longitudinal strip FRP single plate is formed by sticking the longitudinal strip FRP on the surface layer of the longitudinal single plate by using the structural adhesive. Compared with non-enhanced cross-laminated timber, an enhanced component can improve the carrying capacity and the ductility is also increased; the aim of reducing the plate thickness is realized under the same utilization environment so that the unidirectional cross-laminated timber is economic and reasonable.
Description
Technical field
The utility model relates to a kind of reinforcement plate member, is specifically related to the quadrature laminated wood that a kind of band FRP strengthens, and 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.
Utility model content
The utility model is in order to overcome the deficiencies in the prior art, the unidirectional quadrature laminated wood that provides a kind of band FRP longitudinally to strengthen, with respect to the quadrature laminated wood not strengthening, 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.
The technical solution adopted in the utility model is: the unidirectional quadrature laminated wood that a kind of band FRP longitudinally strengthens, the laminate that comprises horizontal gummed, longitudinal glued laminated board and with longitudinal veneer of band FRP, above-mentioned each laminate links together by structure glue or nail, and described longitudinal veneer with band FRP is arranged on the outermost layer that described quadrature laminated wood is subject to tension when curved;
Described longitudinal veneer with band FRP is that the longitudinal FRP of band adopts structure glue to be bonded in the top layer of longitudinal veneer.
As preferably, described FRP material is BFRP(glass fibre reinforced composion), GFRP(basalt fibre reinforcing composite material), CFRP(carbon fibre reinforced composite) in any.
As preferably, described each laminate thickness is between 16-51mm, and each wooden laminate width of sheet is between 60mm-240mm.
As preferably, the width of the longitudinal FRP of described band is 30mm-60mm.
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 unidirectional quadrature laminated wood that described band FRP strengthens, can freely convert laminate reinforcement ratio to meet various enhancing requirements by strengthening width degree and the configuration number of laminate discal patch band FRP.
The beneficial effects of the utility model are: by employing, contain the quadrature laminated wood of band FRP when improving supporting capacity, also increased the ductility of member, in the situation that identical, utilize and under environment, also reach same bearer power, can reduce thickness of slab, the use amount that reduces timber, reaches economic effect.
Accompanying drawing explanation
Fig. 1 is the laterally laminate formation schematic diagram of gummed of the utility model;
Fig. 2 is the longitudinally laminate formation schematic diagram of gummed of the utility model;
Fig. 3 is the formation schematic diagram of longitudinal veneer of the utility model band FRP enhancing.
Fig. 4 is the formation schematic diagram of the utility model quadrature laminated wood.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
As shown in Figure 1: by structure glue, adopt the form of side joint to connect into veneer small bore wood saw material, form quadrature laminated wood horizontal veneer.
As shown in Figure 2: by structure glue, adopt the form of side joint to connect into veneer small bore wood saw material, form quadrature laminated wood longitudinal veneer.
As shown in Figure 3: adopt structure glue to be bonded in the top layer of longitudinal veneer the longitudinal FRP1 of band.
As shown in Figure 4: the longitudinal veneer 2 with band FRP is placed on to orlop, as the outermost layer that is subject to tension when curved, the veneer of the veneer laterally gluing together and longitudinal gummed is combined according to certain mode, and the reasonable time that finally pressurizes forms the good enhancing sheet material of stress performance.The mode of general combination is one willfully go up one vertically, also can adopt two willfully one to indulge or other feasible mode.When adopting gummed, structure glue can adopt PUR, EPI, and PRF, also can adopt nail to carry out being connected of plate and plate.
Should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model principle; some improvements and modifications can also do wrong; these improvements and modifications also should be considered as the scope of the utility model protection, and in the present embodiment, not clear and definite each forms all available existing technology and realized.
