Description

High altitude localities concrete floor heat and moisture preserving maintenance structure

Technical field

The utility model relates to a kind of concrete floor maintenance structure, is specifically related to a kind of heat and moisture preserving maintenance structure at high altitude localities concrete floor.

Background technology

Concrete floor tradition maintenance structure is as follows at present: conventionally adopt laying plastic sheeting or water seasoning mode to carry out maintenance.But, when these modes are applied to high altitude localities, can produce following shortcoming: 1, due to the poor effect of existing plastic sheeting, moisture in concrete outwards scatters and disappears, its ambient humidity, light and temperature decreases, and hydrated cementitious is produced to certain influence, thereby causes the concrete strength of institute's maintenance to reduce; 2, in the larger high altitude localities of day and night temperature, if only do the maintenance of a little moisturizings aspect, and do not take further Insulation, the inside of concrete floor and its surface can form larger temperature difference, form minute crack because temperature stress causes at concrete surface, thereby cause the obvious reduction of concrete strength; 3,, for a long time in and environment that variations in temperature number of times is more large in day and night temperature, inside concrete crack occurrence is all the more serious, causes maintenance effect undesirable; 4, too early artificial construction, causes concrete floor to occur that the probability of defect increases; 5,, in maintenance processes, can cause certain water resource waste.

Therefore, we need a kind of more careful heat and moisture preserving maintenance structure, to make concrete floor can adapt to the adverse circumstances of high altitude localities.

Utility model content

For overcoming the existing defect of prior art, concrete floor heat and moisture preserving maintenance structure in a kind of high altitude localities is now provided, thereby in the large environment of high height above sea level day and night temperature, is subject to ambient temperature variable effect seriously to cause the problem of intensity and Quality Down to solve concrete floor.

For achieving the above object, a kind of high altitude localities concrete floor heat and moisture preserving maintenance structure, comprising: be arranged at the first extruded sheet under flooring bed die; And be arranged at the cavity heat-insulation layer of having built on concrete floor.

The further improvement of the utility model high altitude localities concrete floor heat and moisture preserving maintenance structure is, flooring bed die comprises builds bed die and be arranged at the brace module of building under bed die; Cavity heat-insulation layer comprises: be arranged at the first plastic membranous layer on concrete floor; Be arranged at the second extruded sheet on plastic membranous layer; And be arranged at the second plastic membranous layer on the second extruded sheet.

The further improvement of the utility model high altitude localities concrete floor heat and moisture preserving maintenance structure is, also comprises: be arranged at the cotton carpet veneer on the second plastic membranous layer.

The further improvement of the utility model high altitude localities concrete floor heat and moisture preserving maintenance structure is, the second plastic membranous layer comprises dark high heat absorptivity plastic foil.

The beneficial effect of the utility model high altitude localities concrete floor heat and moisture preserving maintenance structure is: improved to a certain extent concrete and be subject to the impact of high altitude localities variations in temperature, reduced temperature difference between inside and outside concrete, its intensity is better than the concrete strength that adopts traditional maintenance.

Detailed description of the invention

For the benefit of the understanding to structure of the present utility model, describes below in conjunction with drawings and Examples.

Shown in Fig. 1, the utility model provides a kind of high altitude localities concrete floor heat and moisture preserving maintenance structure, mainly comprises: flooring bed die 1; Be arranged at the first extruded sheet 2 under plank sheathing; And be arranged at the cavity heat-insulation layer 3 on formed concrete floor 4.Wherein, flooring bed die 1 forms by building bed die 10 and being arranged at multiple brace modules 12 of building under bed die 10.Ground floor plastic sheeting 30, second layer extruded sheet 32 and second layer plastic sheeting 34 that cavity heat-insulation layer 3 from bottom to top forms successively form.

As shown in Figure 1, in the present embodiment, when completely smooth concrete floor carries out practical application, in flooring bed die 1 under many plank sheathings 12, overlay the thick ground floor extruded sheet 2 of 30mm to carry out insulation at the bottom of plate, to form protection under concrete floor 4; On the concrete floor of having built, first lay the ground floor plastic sheeting 30 that 0.5mm is thick; Then, on ground floor plastic sheeting 30, re-lay the second layer extruded sheet 32 that 50mm is thick; Afterwards, on second layer extruded sheet, re-lay the second layer plastic sheeting 34 that black 0.8mm is thick, to form cavity heat-insulation layer 3 between upper and lower double-layer films; Finally, on second layer plastic sheeting 30, add the cotton felt 5 of one deck.

In the time that daytime, daylight was sufficient, cotton felt 5 is raised, utilize the second plastic sheeting 34 of black to absorb amount of solar heat.Until when 5 to 6 sunshine shortages, cotton felt 5 is restored to covering afternoon.When evening, temperature reduced, cavity heat-insulation layer 3 utilizes ground floor film 30 to intercept extraneous low temperature, and the heat absorbing daytime is conducted to concrete floor 4, thereby reaches the object of insulation.

As shown in Figure 2, when running into the concrete floor that has cylinder 6 projections, can be at elder generation of column cap place covered with plastic film, again according to post muscle spacing, the surrounding saw kerf of cavity heat-insulation layer 3, then filling is wrapped in protruding cylinder 6, finally covers black thin film and cotton felt 5.

Complete after above-mentioned implementation process, just reflect the utility model practical significance: guaranteed curing time, avoided the appearance of cracks on concrete floor defect.

Below embodiment has been described in detail the utility model by reference to the accompanying drawings, and those skilled in the art can make many variations example to the utility model according to the above description.Thereby some details in embodiment should not form restriction of the present utility model, the utility model by the scope defining using appended claims as protection domain.
