Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.In addition, those skilled in the art, according to the description of presents, can carry out respective combination to the feature in embodiment in presents and in different embodiment.
The embodiment of the present invention is as follows, and a kind of construction method suppressing haydite concrete floating shown in Figure 1, comprises the steps:
Step S1, base treatment; Particularly, steel chassis is adjusted to horizontal level, assists leveling by levelling means such as putty if desired, then cleaning mold is clean, and in mould, mainly in mould, base and inner side edge are coated with and brush releasing agent or mould oil.
In step S2, lay bar-mat reinforcement 2; Particularly, lay bar-mat reinforcement 2 in mould, bar-mat reinforcement 2 is worked out by several reinforcing bar anyhow arranged in a crossed manner.Bar-mat reinforcement 2 layers can be one deck, also can be multilayer, specifically can determine according to the purposes of prefabricated component.It should be noted that, when laying multistory reinforced, should preset distance be kept between multistory reinforced net, and shifting to install between adjacent bar-mat reinforcement, namely misplace between reinforcing bar mesh up and down, be so also conducive to the floating of haydite.In addition, also can as required the parts such as built-in fitting and anchoring piece also be defaulted in mould.
In step S3, build haydite concrete 3 and strike off; After laying bar-mat reinforcement 2 and built-in fitting, start to stir haydite concrete 3, and the haydite concrete 3 be stirred is built in mould, haydite concrete 3 layers when building, should be made to sprawl completely and use the instruments such as scraper plate to strike off.It should be noted that, in this step, because the mobility of haydite concrete 3 is better, therefore, without the need to being vibrated by the equipment of vibrating.
In step S4, lay grid cloth 1; Particularly, the grid cloth 1 shown in Fig. 2 is layed on the haydite concrete 3 after striking off, and the specification of grid cloth 1 can be varied, and the material of grid cloth 1 also can be selected as required.In addition, before laying grid step, larger haydite particles should be removed, or carry out compacting.
In step S5, rolling; Particularly, carry out roll extrusion by rolling device to the haydite concrete 3 being equipped with grid cloth 1, until the slurry of haydite concrete 3 completes be covered in grid cloth 1, namely grid cloth 1 sinks in haydite concrete 3 completely.
In step S6, shaping and demoulding; Maintenance is carried out to haydite concrete 3, as regular watering, keeps the temperature and humidity of appropriateness, can till the demoulding until haydite concrete 3.
On the basis of above-described embodiment, in another embodiment of the present invention, in step S2, when laying bar-mat reinforcement 2 in mould, build graduation mark at die inside mark, graduation mark marks according to the thickness of prefabricated component, and notation methods is varied simultaneously, can be marked by span wire system, can also be marked by modes such as setting-outs on internal mold.
On the basis of above-described embodiment, in another embodiment of the present invention, in step S2, as shown in Figure 3, bar-mat reinforcement 2 comprises two-layer up and down, and two-layer bar-mat reinforcement 2 interval is arranged, and concrete spacing distance can regulate according to the thickness of prefabricated component.
On the basis of above-described embodiment, in another embodiment of the present invention, in step S4; when laying grid cloth 1; laying need be completed in after haydite concrete 3 has been built 20 minutes, as interval is oversize, then grid cloth 1 may be caused cannot to be embedded in haydite concrete 3.In addition, for grid cloth 1, as shown in Figure 2, the every object specification of grid cloth 1 is preferably 8mmx8mm to 12mmx12mm, and, during laying, should ensure that grid cloth 1 is covered on concrete comprehensively.
On the basis of above-described embodiment, in another embodiment of the present invention, in step S4, for the laying of grid cloth 1, preferably after haydite concrete 3 has been built, complete laying in 15 minutes, at this moment in section, grid cloth 1 is easier to embed in haydite concrete 3.
On the basis of above-described embodiment, in another embodiment of the present invention, in step S5; when namely rolling being carried out to haydite concrete 3; preferred employing length is 20 inches, and the froth breaking cylinder that nail grows to few 12mm carries out roll extrusion to grid cloth 1, till making the comprehensive grid coverage cloth 1 of haydite concrete 3 slurry.
On the basis of above-described embodiment, in another embodiment of the present invention, step S3, to step S5, namely from building haydite concrete 3, then strikes off, and lays grid cloth 1, and extremely finally haydite concrete 3 rolling, three steps need complete in 15 minutes.As the time is oversize, the amalgamation of grid cloth 1 and haydite concrete 3 will be affected, and then affect the quality of prefabricated component.
On the basis of above-described embodiment, in another embodiment of the present invention, in step S6, the prefabricated component built up is watered to haydite concrete 3 and carries out maintenance, cover film on prefabricated component, ensure that prefabricated component is in suitable temperature and humidity, until the final demoulding.
On the other hand, the present invention also proposes a kind of prefabricated component, and particularly, prefabricated component obtains based on the construction method of haydite concrete floating that suppresses as above.By the prefabricated component that said method obtains, preferably resolve the problem of haydite floating in concrete, surfacing, function admirable.
On the basis of above-described embodiment, in another embodiment of the present invention, the cross sectional shape of prefabricated component as shown in Figure 3, the grid cloth 1 that prefabricated component adopts is specially alkali-proof glass fiber mesh, further, the concrete thickness of grid cloth more than 1 is 2mm-20mm, and namely grid cloth 1 embeds in prefabricated component 2 to 20mm.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
