Description

A kind of support construction and its application
Technical field
The invention belongs to civil engineering structure field more particularly to a kind of support construction and its applications.
Background technology
Timber structure is not only most important structure type in China's traditional architecture or the important composition portion in infrastructure Point.Timber is that building field is one of common raw material, on the one hand, timber have lighter weight, strength parallel to grain higher and Advantages of environment protection;On the other hand, timber is biomaterial, and deformation increases after being moistened, while also suffering from naturally The influence of defect, bacterium, worm, high temperature, high humidity and etching medium, causes timber structure to need periodic maintenance and reparation.Due to timber Performance may suffer from prodigious damage during service life, for timber structure of the remote past or newly-built timber structure, repair It is urgently to be resolved hurrily with endurance issues.
In recent years, fibre reinforced composites (Fiber Reinforced Polymer, FRP) are widely used in coagulation In soil structure and other structural strengthenings;FRP have lightweight, high-strength, corrosion-resistant, ductility is good and excellent with wood good compatibility Point, existing research reinforce pin using the wet bonding techniques of FRP, and pin all obtains bright in bearing capacity, ductility and shock resistance after reinforcing It is aobvious to be promoted.However, there is following disadvantages by FRP, such as:Non-refractory, be not suitable in moist surface or low temperature condition and The cost of epoxy resin is higher.
Currently, both at home and abroad having fiber reinforced cement-based composite material compared with in-depth study and application, especially adding Gu being made great progress in terms of concrete structure.Fiber knitted net enhances cement-based material (Textile Reinforced Concrete, TRC) overcome that ordinary reinforced concrete durability is poor, crack resistance is poor, from the fatal defects such as great, and it is strong at it Degree, ductility have a distinct increment in shock resistance, and the concrete/cement mortar for becoming most potential, which is expanded, applies alternative materials, and water There are problems that making of mud base solves composite fireproof poor performance.
In the prior art, it is for having the existing restorative procedure of timber structure:Traditional replacement Local Damaged material is simultaneously noted It penetrates resin filling or other materials filling crack, reinforced with metal machinery device or metal cap and the wet bonding of FRP is reinforced etc..It passes There is some defects for the reinforcement and repair method of system, such as:Injecting resin is often obtained the enhancing degree of pin by subjective experience It arrives, high for the skill requirement of technical staff, repair efficiency is poor;When being reinforced using metallic sheath or metal cap, metal and wood There are compatibility issue between material, there is also corrosion problems for metal itself;Using the wet viscous reinforcing pins of FRP using full package or Equidistantly the form of package pin is reinforced, and for wrapping up entirely, the FRP and amount of resin of consuming are larger, and cost is higher, right For equidistantly discontinuous package, some pin exposes in air, reduces the service life of timber, whether All there is high temperature resistance difference in full package or equidistantly package.
Therefore, a kind of support construction and its application are developed, for solving in the prior art, the reinforcing of timber structure there is Good consolidation effect can not be taken into account simultaneously, reinforces durability and the cheap technological deficiency of reinforcement cost, become this field Technical staff's urgent problem to be solved.
