Abstract

A bedding for curing concrete consists of a water-absorbing layer, a surface layer and a lower covering layer that are compounded sequentially; an upper surface layer is longer than the water-absorbing layer and the lower covering layer and can wrap the two layers; the water-absorbing layer is made of melamine heat-preserving sponge; the upper surface layer is made of scraping and twining cloth; and the lower covering layer is made of synthetic fiber nonwoven fabric. The bedding is a concrete curing product, which is convenient for use, is water-saving and effort-saving and pure, has no pollution, can keep the humidity of the concrete curing surface in a long time, and can ensure the curing quality of the concrete.

Description

A kind of bed clothes of curing concrete

Technical field

The utility model relates to a kind of concrete maintenance product, is applicable to the maintenance that adds in the concrete formation process.

Background technology

Temperature difference between inside and outside concrete is one of major reason that causes concrete cracking, in order to obtain good concrete quality, behind concrete formation, must carry out maintenance, to guarantee normally carrying out of cement hydration process.Under the suitable situation of temperature, keep the temperature of concrete surface just to become the factor of concrete curing most critical.At concrete construction site, the method that traditional concrete curing method adopts grass (fiber crops) bag oversite concrete surface usually and waters, this method is owing to fail grass (fiber crops) bag and concrete surface and outside air isolation, thereby maintenance effect has been subjected to the influence of dry air, particularly in summer, strong solar radiation makes water evaporates very fast, guarantee that quality of concrete must ceaselessly water, thereby water consumption is big, the labour intensity height; Also existence grass (fiber crops) bag is easy to rot simultaneously, the life-span is short, pollute shortcomings such as concrete surface and environment.

Summary of the invention

That the purpose of this utility model provides is easy to use, water saving, saving of labor, totally pollution-free, and can keep the humidity of concrete curing face in a long time, and can guarantee a kind of concrete curing product of concrete curing quality.

The utility model is to constitute like this: a kind of bed clothes of curing concrete are to be composited in proper order by water accepting layer, superficial layer and lower caldding layer, and its upper surface layer is longer than water accepting layer and lower caldding layer.

The bed clothes of described a kind of curing concrete, its water accepting layer are to adopt the melamine insulating sponge to make.

The bed clothes of described a kind of curing concrete, its superficial layer are to adopt to be coated with to scrape the folder screen cloth and make.

The bed clothes of described a kind of curing concrete, its lower caldding layer are to adopt the synthetic fibers non-weaving cloth to make.

The utility model is compared the characteristics that had with existing background technology: this maintenance bed clothes are before use because water accepting layer has absorbed certain moisture, these moisture are covered by film, even can very fast volatilization under sunburst irradiation yet, inherent concrete surface of long period has formed a kind of approximate saturated maintenance environment like this, has reached the purpose to the good maintenance of concrete.Therefore, this product is easy to use, water saving, clean, pollution-free, and can keep the humidity of concrete curing face in a long time and change little temperature, thereby has kept concrete maintenance quality to greatest extent.

Description of drawings:

The bed clothes sectional schematic diagram of a kind of curing concrete of Fig. 1;

The construction drawing of the bed clothes of a kind of curing concrete of Fig. 2;

The A-A profile of the bed clothes of a kind of curing concrete of Fig. 3.

It is as follows that the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:

Among the figure: 1 is that water accepting layer, 2 is that superficial layer, 3 is that lower caldding layer, 4 is that newly-laid concrete, 5 is that sewing line, 6 is snap-fastener.

The specific embodiment

The described concrete curing bed clothes of the utility model (Fig. 1) are to be composited by superficial layer 2, water accepting layer 1 and lower caldding layer 3 orders, and water accepting layer 1 is to adopt the melamine insulating sponge to make; Upper surface layer 2 is to adopt to be coated with to scrape the folder screen cloth and make; Lower caldding layer 3 is to adopt the synthetic fibers non-weaving cloth to make.

Water accepting layer 1 is for having the industrial products of enough water imbibitions and heat insulating ability.Before concrete curing, earlier outside moisture is sucked its inside, in the concrete curing process, discharge contained humidity gradually, to keep the humidity of concrete curing face, its thickness is decided according to the maintenance environmental condition, is generally 6 to 90 millimeters and is advisable.

Superficial layer 2 is for having water proof, ageing-resistant and industrial products with certain intensity.Its effect one is the water evaporates that prevents in the water accepting layer 1, the 2nd, and the bulk strength of increase maintenance bed clothes.

Lower caldding layer 3 should be selected high water-permeability, high-intensity industrial products for use, so that pour mass can be discharged bubble and excessive moisture easily and can be carried out good maintenance action to concrete.In the concrete curing process and maintenance when finishing, play effective protective effect by 3 pairs of water accepting layers 1 of lower caldding layer, increase the service life of concrete curing bed clothes.

The maintenance bed clothes in use, lower caldding layer 3 with contacted by newly-laid concrete 4 surfaces of maintenance, superficial layer 2 outwardly, the moisture in the water accepting layer 1 sees through lower caldding layer 3 and keeps the humidity on newly-laid concrete 4 surfaces.

Adopt the maintenance bed clothes of such structure fabrication, can significantly reduce the water consumption in the concrete curing, reach purpose easy to use, water saving.Simultaneously, concrete surface and surrounding environment are not polluted.

The planar dimension of maintenance bed clothes and size need be determined according to engine request, and its periphery need be made (Fig. 2,3), can make a call to a circle hole (Fig. 2) on its periphery, or do some snap-fasteners or velcro along its periphery.Fig. 3 is a kind of pattern that concrete curing bed clothes periphery is made, and upper surface layer 2 is longer than water accepting layer 1 and lower caldding layer 3, and can wrap that this is two-layer, and 5 is sewing line.

Claims

1, a kind of bed clothes of curing concrete are composited by superficial layer (2), water accepting layer (1) and lower caldding layer (3) order, it is characterized in that upper surface layer (2) is longer than water accepting layer (1) and lower caldding layer (3).

2, the bed clothes of a kind of curing concrete according to claim 1 is characterized in that superficial layer (2) is to adopt to be coated with to scrape the folder screen cloth and make.
