Abstract
The present invention relates to concrete structure and component reinforcement. It features that the adhesive is inorganic adhesive material formed by means of polymerization of resin emulsion or curing agent, quarzite powder, cement and other material and hydration reaction of cement inside the epoxy emulsion containing 50% water. The construction process is anchoring one. The advantage of the present invention is that the original steel bar and the reinforcing steel plate have synchronous stress and solving the problem of ageing makes the said reinforced structure durable.
Description
The present invention relates to matrix material and worker's method of building concrete structure and strengthening member, particularly steel clad reinforcement.
The stick that prior art stick steel plate (muscle) reinforced concrete technology is used is epoxy resin series or modified epoxy resin, is commonly called as structure glue, all is macromolecular material.These binding agents have following shortcoming: 1) aging easily; 2) Young's modulus of epoxy resin binding agent is than the low magnitude of concrete, therefore during concrete deformation, material transfer stress by this low elastic modulus then can cause the asynchronous and response lag of stress between steel plate and the concrete to steel plate, and outer sticking steel plate surpasses the wasting phenomenon of elastic stage far away with regard to causing former beam steel yield failure like this; 3) because epoxy glue is little compared with concrete and steel plate density, it is low to play mould, and capacity is few, cause by temperature deformation or stress deformation inharmonious, asynchronous, will cause concentrated the gathering and fatigue of interfacial stress between the material like this, aging thereby the destruction interfacial adhesion is called interfacial adhesion again.The shortcoming of above-mentioned materials makes Baogang's plate reinforcement method be difficult to development, also is judged to be interim method for strengthening by many experts.
Reinforcing worker method before the appearance is used interim the support, and following shortcoming is arranged: 1, the spatial of interim support around can influencing under many circumstances be set normally use, the work cost is raise, in some cases or even unallowed; 2, the interim support is provided with normal force, is feasible for objects such as beam slabs, but just is difficult to the support of normal force has been set for objects such as shearwalls, limited the use range of steel bonding technology like this.
It is good to the purpose of this invention is to provide a kind of ageing-resistant performance, easy construction, and use range is extensive, and Baogang's binding agent and the constructional method that can forever reinforce.
Technical scheme of the present invention is: adopt polymer water mud to replace polymer pure organic materials---epoxy glue as binding agent.The composition and the proportioning of polymkeric substance are as follows: resin emulsion: solidifying agent: silica powder: cement=18～23: 4～7: 20～25: 40～55.Constructional method comprises: plumbous bolt hole on member, expansion bolt is installed, and the component surface concrete is coated with interfacial agents and makes interface processing, with above-mentioned matrix material affixing steel plate, tightens the nut of expansion spiral shell inspection.
Advantage of the present invention: 1) matrix material is made up of inorganic materials, effectively solves problem of aging, makes the steel bonding method become permanent strengthening method; 2) the stress sync rates that makes former reinforcing bar and the strong steel plate of reinforcement is up to 99%, and the required power transmission of steel plate and member co-operation is made of jointly the cohesive force of matrix material and the normal direction stress that adds in advance of expansion bolt, and strcture safety is higher; 3),, also reduced construction costs simultaneously for the normal use of buildings is provided convenience because the pressuring action of expansion bolt need not be provided with interim support.
The present invention has adopted polymer water mud as binding agent replacement polymer pure organic materials---epoxy glue, this material main composition is resin emulsion, cement, silica powder, or solidifying agent, the trade name of this glue is a TN glue, because the epoxy that is emulsification, cement plays hydration reaction in the epoxy emulsion that contains 50% moisture content, form cement inorganic material, thereby the ageing-resistant performance of the strong mechanical performance of organic materials and inorganic materials has been combined well.Combination like this improves the induration shearing modulus of elasticity of NT glue, from original pure epoxy 10 widely in addition
2Mpa brings up to 10
3Mpa has so just solved the common fault of traditional assembly glue effectively.
Concrete enforcement prescription and effect are as follows:
One, epoxy emulsion: polyamine: silica powder: 525# ordinary Portland cement=20: 5: 23: 52
Its main mechanical performance index is as follows:
Set time: 5 hours
Bonding shear strength (the 10 day length of time): 3.01Mpa～4.0Mpa
Bonding bending and tensile strength (the 10 day length of time): 2.71Mpa～3.5Mpa
Bonding cube ultimate compression strength (the 28 day length of time): 23.0Mpa～40Mpa
Pressure-proof elasticity modulus (the 38 day length of time): 1.05 * 10
4Mpa
Shearing modulus of elasticity (the 30 day length of time): 3.57 * 10
3Mpa
Two, cationic chloroprene latex: polyamine: silica powder: cement=18: 4: 20: 55.Mechanical performance index is the same.
Constructional method of the present invention has been improved the interim in the past way that supports, and replaces with permanent anchor pole.Normal force before more effectively providing glue paste fixed, permanent anchoring have increased interface shearing-resistance cohesive force (but not making basis, a do insurance coefficient).
Constructional method of the present invention has comprised: auger shell keyhole on member; Expansion bolt is installed; The component surface concrete is coated with interfacial agents and makes interface processing; Use the matrix material affixing steel plate; Tighten the nut of expansion bolt.Further specify the present invention below by accompanying drawing.
Among the figure, concrete member 1, steel plate 2, matrix material 3, interface 4, expansion bolt 5.
