Abstract

The invention discloses a method for preventing an outdoor building from accelerating deterioration and a surface of a finishing coat from being separated out pollutant. A concrete structure laid with the finishing coat outdoors is provided with a water drain and air guide device. The method is as follows: in the concrete structure laid with the finishing coat outdoors, a plurality of water drain holes and air guide holes are arranged at preset intervals, inlet heights of the water drain holes and the air guide holes are larger than outlet heights, so that water permeating each structural layer between the finishing coat and the concrete structure can be discharged through the water drain holes and the air guide holes in a natural mode in time under the actions of gravity, sunshine, temperature difference and air convection, so as to avoid the water accumulated between the finishing coat and a concrete member intensifying deterioration of a material in each structural layer and separate out hydrolytic substances such as calcium hydroxide and the like in cement products to pollute the finishing coat. The method has the advantages of simple technical means, convenient construction, and common and easily obtained materials with low cost, and can be widely applied to various building constructions.

Description

The method of pollutant is separated out on a kind of outdoor building accelerated deterioration and finish coat surface of preventing
Technical field
The invention belongs to construction engineering technical field, be specifically related to a kind of outdoor building accelerated deterioration and finish coat surface of preventing and separate out the method for pollutant.
Background technology
Outdoor building thing such as bridge, road, outdoor class and its finish coats of building such as step ladder, outdoor square terrace, be exposed in the atmosphere all the year round, not only to bear effects such as People's Bank of China tramples on, vehicle rolls, but also constantly be subjected to Exposure to Sunlight, the temperature difference, do the influence of external force alternate cycles such as wet.Techonosphere between its finish coat and the concrete structure often exists percolating water or ponding.Though in the prior art, some building is provided with waterproofing materials or structure on its surface, but still can not avoid the infiltration of outside moisture content fully.Simultaneously, since the finish coat gas permeability of outdoor building a little less than, the moisture that accumulates in each techonosphere between outdoor building finish coat and the concrete structure is difficult to disengage voluntarily usually, this has not only aggravated the physicochemical property deterioration of concrete structure and each techonosphere material, and the hydrolyzable materials such as calcium hydroxide in the cement products, under the effect of water, can constantly expand, dissolve, and then be transported to building surface with moisture content gradually, at the water evaporates post crystallization or separate out, pollute the impression of outdoor building finish coat.
The root of the problems referred to above all is the intrusion of water and can't in time discharges and cause.If can manage the moisture that amasss each techonosphere between finish coat and the concrete structure with oozing, drain within a short period of time, reduce the time that moisture stops in each techonosphere between finish coat and concrete structure, make concrete structure recover dry state rapidly, obviously be provided with and stop moisture content to ooze to amass material or the structure in each techonosphere between finish coat and the concrete structure, more reliable, economy and easy.In addition, can recover to do wet balance in the short time after its member of outdoor building makes moist, help guaranteeing globality, stability and the durability of each techonosphere of outdoor building greatly, guarantee that the physicochemical property of material does not reduce substantially, can effectively delay its deterioration, prolong the building life-span.
Summary of the invention
According to above shortcomings in the prior art, technical problem to be solved by this invention is, deterioration and pollution problems appear easily in order to solve existing outdoor building, the invention provides a kind of employing and dredge but not shutoff, prevent that outdoor building accelerated deterioration and finish coat surface from separating out the method for pollutant.
The technical scheme that the present invention is adopted for achieving the above object is:
