Abstract

The invention discloses a reinforced laminate vertically embedded with FRP (Fiber Reinforce Plastic), a laminated wood beam and a pillar member, belonging to the field of construction material manufacture. The reinforced laminate vertically embedded with the FRP mainly comprises a wood composite material part and an FRP laminate part, and can be used for improving performances of the laminated wood beam and a pillar structure; in the process of manufacturing a laminated wood member, the original wood laminate is replaced by the reinforced laminate vertically embedded with the FRP, so that the bearing capacity of the laminated wood member can be obviously improved; and through the novel FRP arrangement manner, the possibility of peeling destruction between the FRP and the wood laminated surface in the traditional FRP reinforcement manner can be effectively reduced. According to the reinforced laminate vertically embedded with the FRP, the laminated wood beam and the pillar member, various reinforcement requirements can be met through freely changing an FRP reinforcement ratio via changing the thickness and the arrangement number of FRP slabs, and the reinforced laminate can be used for the reinforcement of the laminated wood beam and the pillar member.

Description

The enhancing laminate of a kind of perpendicular embedding FRP and gummed wooden frame, post member
Technical field
The present invention relates to a kind of enhancing sheet material and gummed wooden frame, post member, be specifically related to the enhancing laminate of a kind of perpendicular embedding FRP and glue together wooden frame, post member, main (but not exclusively) is used for the enhancing of gummed wooden frame, post member.
Background technology
Now Domestic wood raw material structure generation major transformation, path low-quality timber will become primary raw material, and high-quality log reduces day by day in the world wide, price is lasting rises; The simultaneously development of petrochemical industry is so that the structure prices of glue; High-tech process technology has been successfully applied to wood-processing industry, and these all provide good opportunity for the development of China's modern project wood structure.
Engineered Wood Product Manufacturing is take log as main raw material(s), adopts high-performance environmentally-friendly type adhesive, the composite wood that utilizes the modern timber process technology to make.Engineered Wood Product Manufacturing has not only kept the desirable natural characteristic of solid wood sawn timber, but also have that material is even, permissible stress is high, good stability of the dimension, protection against the tide, the characteristics such as anticorrosion, fire-retardant; Its appearance has improved the utilization rate of timber, and for intensity and the reliability of timber buildings provides powerful guarantee, trimmed size flexibly and can adapt to multiple needs is convenient to realize batch production production, for the sustainable development that realizes forestry is laid a good foundation.
Modern timber buildings is main with the building types of laminated wood as main bearing member such as beam and columns, the timber ratio of strength to weight is large, but specification is limited, and more piece, therefore to be applied in building structure field, still need to further investigate at aspects such as mechanical strength and structural performances.
The advantages such as fibre reinforced composites (FRP) have lightweight, high-strength, corrosion-resistant, easy cutting, application property is good, saving is artificial, reinforcing wooden construction with FRP is used widely, not only can improve bearing capacity, rigidity and the ductility of wooden frame and pin, also can improve durability and the Creep Characteristics of wooden construction.It is whether the adhesive property of FRP and wooden construction can guarantee both co-operation that FRP reinforces one of basic theory problem of most critical in the timber structural techniques, and timber and FRP glue-line stripping damage also are a kind of mode of failure of FRP enhancing glue laminated wood member.
Summary of the invention
The objective of the invention is in order to overcome the deficiencies in the prior art, the enhancing laminate of a kind of perpendicular embedding FRP is provided, when the glue laminated wood member after the enhancing improves supporting capacity, also increased the ductility of member, special FRP arrangement of while has been avoided the cementing of the wooden laminate of the large tracts of land of traditional F RP enhanced form and FRP plate, the substitute is the identical line of timber to gummed, effectively reduce because of the glue-line between FRP and timber and peel off the possibility that causes component damage.
Another object of the present invention provides a kind of laminated wood beam of enhancing laminate of perpendicular embedding FRP plate.
Another object of the present invention provides a kind of gummed pin member of enhancing laminate of perpendicular embedding FRP plate.
The technical solution used in the present invention is: a kind of enhancing laminate of perpendicular embedding FRP plate, comprise 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 can be the BFRP(glass fibre reinforced composion), the GFRP(basalt fibre reinforcing composite material), the CFRP(carbon fibre reinforced composite) in any.
As preferably, the thickness of described FRP plate is 1~4mm.
The enhancing laminate of described perpendicular embedding FRP plate can be by FRP plate in the conversion laminate thickness and the free conversion laminate of configuration number reinforcement ratio to satisfy various enhancing requirements.
Perpendicular embedding FRP laminate of the present invention is desirable to be used for being glued at the tension side tension side of gummed wooden frame or compression-side or tension, pressurized bilateral, and the skin of gummed pin, can better bring into play its humidification.
A kind of laminated wood beam that uses the enhancing laminate of above-mentioned perpendicular embedding FRP plate, comprise the enhancing laminate of perpendicular embedding FRP plate and the gummed wooden frame that is formed by many wood strips laminate gummed, the enhancing laminate of described perpendicular embedding FRP plate is glued at the tension side of gummed wooden frame or compression-side or tension, pressurized bilateral.
A kind of gummed pin member that uses the enhancing laminate of above-mentioned perpendicular embedding FRP plate comprises the enhancing laminate of perpendicular embedding FRP plate and the gummed pin that is formed by many wood strips laminate gummed, and the enhancing laminate of described perpendicular embedding FRP plate is glued at the skin of gummed pin.
The invention has the beneficial effects as follows: when the glue laminated wood member after strengthening by the present invention improves supporting capacity, also increased the ductility of member, simultaneously special FRP arrangement effectively reduces because of the glue-line between FRP and timber and peels off the possibility that causes component damage.
