Description
Technical field
The present invention relates to a kind of masonry construction method, more particularly, to a kind of construction method of winter masonry project.
Background technology
The winter of northern China and cold district, due to prolonged consecutive low temperature, the temperature difference is big, high wind, snowfall and frost,
Weather conditions are poor.When estimated continuous 10 days outdoor temperature on average is less than 5 DEG C, or beyond the winter construction time limit, same day gas
When temperature is less than 3 DEG C, masonry project will require to carry out according to winter construction.
Winter, most significant influence was that mortar is freezed by cold service.The mortar freezed will appear from stopping hardening, lose
Cementation and intensity, plasticity significantly reduce, mortar joint compactness weakens, it is uneven to be produced under the load action of mortar defrosting upper back
The drawbacks such as sedimentation.Therefore, the winter construction of masonry project needs to take corresponding measure from many aspects.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide a kind of winter masonry project
Construction method.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of construction method of winter masonry project, comprises the following steps:
S1, the dirt for removing building material surface, reject the fragment of brick freezed by immersion;
If S2, lime paste freeze, melt lime paste;
S3, mix well sand and it is not contained diameter and freeze block and ice cube more than 10mm;
S4, in advance heating sand are to 20~35 DEG C, and for heating water to 40~70 DEG C, environment temperature is not less than 5 DEG C of mixing mortars,
Mixing time increases by 0.5~1 times than normal temperature situation;
S5, build masonry by laying bricks or stones, vertical mortar seam is filled up before daily knock off, does not spread mortar above, is covered and built with insulation material
Body upper surface.
The mortar includes sand, water, cement, lime paste and antifreezing agent.
Ratio of the antifreezing agent in mortar is 6~7%.
The mortar also includes modified foaming agent, and its ratio in mortar is 0.1~0.3%.
The denseness when mortar is used in porous brick masonry is in 90~120mm, and denseness is 45 when being built by laying bricks or stones used in ashlar
~60mm.
Directly transported after the mortar mixing, do not accumulate Secondary Transport, the storage time of mortar is no more than 15min.
The mortar when building masonry by laying bricks or stones temperature more than 5 DEG C.
Compared with prior art, appropriate antifreezing agent is added in mortar of the present invention prevents mortar hardening, and mixes appropriate change
Property foaming agent, so as to improve the workability of mortar, freeze thawing resistance cyclicity and durability, and can save the dosage of cement;To water and
Sand uses advance mode of heating, and mixing time increases by 0.5~1 times than normal temperature situation, is advantageous to the uniformity of mortar, water temperature is 40
~70 DEG C will not produce false set because temperature is too high;Heat insulation work is carried out when knocking off daily in construction to masonry, ensures and builds
Body will not occur low temperature bursting by freezing phenomena such as.
Brief description of the drawings
Fig. 1 is the construction method of winter masonry project of the invention.
Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.The present embodiment is with technical solution of the present invention
Premised on implemented, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to
Following embodiments.
As shown in figure 1, a kind of construction method of winter masonry project, comprises the following steps:
S1, the dirt for removing building material surface, ice and snow etc., reject the fragment of brick freezed by immersion;
If S2, lime paste freeze, melt lime paste;
S3, mix well sand and it is not contained diameter and freeze block and ice cube more than 10mm, ensure mortar quality;
S4, in advance heating sand are to 20~35 DEG C, and for heating water to 40~70 DEG C, environment temperature is not less than 5 DEG C of mixing mortars,
The frame stove that can be put up a shed by mixer is incubated, and mixing time increases by 0.5~1 times than normal temperature situation, and sand field is covered with tent, works as gas
It is incubated when temperature is relatively low using brooder, prevents sand from freezing, but sand must not the calcination on steel plate;
S5, build masonry by laying bricks or stones, vertical mortar seam is filled up before daily knock off, does not spread mortar above, with insulation material by masonry
Upper surface is covered, and when building by laying bricks or stones within second day, first should be swept only the frost and snow on masonry surface, can be continued to build by laying bricks or stones.
Mortar includes sand, water, cement, lime paste and antifreezing agent, and wherein ratio of the antifreezing agent in mortar is 6~7%,
Antifreezing agent is qualified using inspection and through the satisfactory product of laboratory's match ratio trial.Mortar also includes modified foaming agent, its
Ratio in mortar is 0.1~0.3%, can improve the workability, freeze thawing resistance cyclicity and durability of mortar, and can save
The dosage of cement.
Denseness when mortar is used in porous brick masonry in 90~120mm, when being built by laying bricks or stones used in ashlar denseness 45~
60mm。
Directly transported after mortar mixing, do not accumulate Secondary Transport, the storage time of mortar is no more than 15min.
Mortar is after stirring, transporting, and temperature is more than 5 DEG C when building by laying bricks or stones.Without using the mortar freezed, not by heat
Stirring use again in mortar is freezed in water incorporation, and also not when building by laying bricks or stones, into mortar, water mixing uses.Under the conditions of subzero temperature, when laying bricks
Do not sprinkle water moistening.
