Description
Technical field
The invention belongs to building material technical field, more specifically relate to a kind of PTB inorganic environment-friendly inserted bar adhesive and using method thereof.
Background technology
The buildings that China built up in the 1950's～sixties has quite a few and has entered person in middle and old age's phase, need detect consolidation process to it, because it is before not enough to concrete performance understanding, each side such as the design of concrete structure, control of construction quality, choices of raw materials are only being laid particular emphasis on concrete mechanical strength and stability of structure, life requirement is not proposed, make concrete structure have many problems and hidden danger, these structures As time goes on, will deterioration, damage causes use properties to descend, and makes structure can not continue to use; Simultaneously, also there are a considerable amount of buildingss need change functions of use, as the increasing of the change of buildings design, floor, the change of house purposes, the increase of structural load etc. along with the development of society and the raising of people's living standard.How under the principle that guarantees primary structure member reliability, to remodel and expand, reduce construction investment again as far as possible, become the problem that industries such as architectural design, construction and building materials must be faced.
In recent years, along with the development of building technology and the introduction of advanced foreign technology, some technical problems that are difficult in the past overcome have progressively obtained solution, new technologies such as bar planting, affixing steel plate, stickup carbon fiber, novel material begin utilization gradually in the engineering reconstruction is reinforced, wherein the bar planting anchoring is because cheap, the simple and widespread use in engineering of constructing operation.
The most frequently used bar planting glue is organic bar planting glue at present, organic bar planting glue has its significant advantage, such as early strength height, full-fledged etc., but organic bar planting glue also has the shortcoming that it is difficult to overcome, such as differ too big with concrete Young's modulus, resistance toheat is poor, easily wear out, have little poison, price is high.
Yet inorganic bar planting glue can solve the problem that organic bar planting glue exists, and it has a lot of advantages:
(1) the main raw material of inorganic bar planting glue generally is inorganic materials such as concrete and silicate, and Young's modulus is close with former concrete, so and former concrete work Harmony better, under temperature and stressed variation, colloid and concrete are difficult for breaking away from.
(2) inorganic bar planting glue resistance toheat is good, and the Applicable temperature scope of general organic bar planting glue is at-35～60 ℃, and nearly all organic materials is non-refractory all, and the heatproof of compound resin is no more than 250 ℃, and the heatproof of " plastics king " tetrafluoroethylene is also not as good as 400 ℃; When reaching 360 ℃, the intensity of organic bar planting glue just begins to have descended.And in the middle of some engineerings, such as chimney, industry cellar for storing things stove etc., temperature is generally all between 300～600 ℃, in this case, organic bar planting glue just is difficult to be suitable for, and cement base inorganic bar planting glue complete energy works better under this temperature, heat-resisting inorganic bar planting glue after treatment is safe working below 600 ℃.
(3) inorganic bar planting glue main raw material is cement and silicate mostly, adds various admixtures, and is nontoxic, tasteless, and it has overcome the shortcoming with little poison of organic bar planting glue, protected workmen's health in construction process.And inorganic bar planting glue generally is to prepare glue before injecting glue earlier, so more convenient and simple than organic bar planting glue construction.
Although inorganic bar planting glue development is very fast, and uses more and more widely, existing inorganic bar planting glue still has some significant disadvantages at present:
(1) inorganic bar planting glue time of reaching certain intensity still is long, though shortened much the time of coagulation of the time of coagulation of the inorganic bar planting glue of short-term strength cement base than the inorganic bar planting glue of Portland cement base, but with respect to organic bar planting glue, tangible gap is still arranged, thereby had influence on range of application.
(2) bulk strength of inorganic bar planting glue also needs further to improve.At present, the anchorage depth of inorganic bar planting glue generally all needs to reach about 15d, when running into concrete wall and concrete slab structure, because original concrete thickness low LCL causes inorganic in this case bar planting glue to use.Though the method for the inorganic bar planting of band conehead can shorten anchorage length, this method is constructed cumbersome comparatively speaking.
So press for a kind of novel inorganic environment-friendly inserted bar adhesive at present, bring spring for the reinforcing industry, bring good economic benefit and social benefit.
PTB inorganic environment-friendly inserted bar adhesive of the present invention can overcome the shortcoming of existing inorganic bar planting glue, has remarkable economic efficiency and social benefit.
Summary of the invention
The purpose of this invention is to provide a kind of PTB inorganic environment-friendly inserted bar adhesive, its Young's modulus and concrete are close, fire-resistant, heat-resisting, nontoxic, tasteless, cheap, work-ing life is identical with concrete structure, have wide range of applications, preparation process is simple, and using method is simple and direct, be fit to large-scale promotion application, have remarkable economic efficiency.
PTB inorganic environment-friendly inserted bar adhesive of the present invention is made up of the PTB aqueous solution and bar planting rubber powder material; The weight ratio of the described PTB aqueous solution and bar planting rubber powder material is: 0.1～0.3: 1.
The using method of PTB inorganic environment-friendly inserted bar adhesive of the present invention is: the using method process is: location → boring → clear hole → steel rust removing → PTB inorganic environment-friendly inserted bar adhesive preparation → bar planting → curing, protection → check.
Remarkable advantage of the present invention is: the rapid hardening cement that uses in the raw material of the present invention is a kind of mineral binder bond, and it and water generation hydration reaction generate the C-S-H gel, make the intensity fast development of inorganic bar planting glue.The PTB emulsion is a kind of organic binder bond, carrying out along with hydration process, the dehydration of PTB emulsion forms polymeric film, around the cavity that this film continuous distribution is produced when cement solidification, they are bonded to a firm integral body firmly, and across the microscopic checks in the sand-cement slurry hardenite, the connection of shuttling back and forth, when stressed, become whippy " hinge " structure, both disperse stress concentration, increased resistance capacity to deformation again, thereby improved the cohesive strength of inorganic bar planting glue, PTB inorganic environment-friendly inserted bar adhesive Young's modulus of the present invention is close with concrete, fire-resistant, heat-resisting, nontoxic, tasteless, work-ing life is identical with concrete structure, and compares with other bar planting glue, find that the inorganic bar planting glue of PTB has better economic, have wide range of applications, preparation process is simple, and using method is simple and direct, be fit to large-scale promotion application, have remarkable economic efficiency.
