Abstract

The invention discloses a construction method for dry-mixed mortar and belongs to the field of buildings. The construction method for the dry-mixed mortar comprises the following steps that 1, sand of the dry-mixed mortar is supplied independently without drying; 2, other components, except the sand, of the dry-mixed mortar are used for producing a finished cement mixture product by dry-mixed mortar manufacturers; 2, the sand and the cement mixture are transported to a construction side independently and stored; 4, the sand and the mixture of other components are conveyed onto a construction working face independently by means of an airtight wind conveying system; and 5, the sand and the mixture are mixed by adding water on the construction working face, so that wet mortar meeting use requirements is formed. The construction method for the dry-mixed mortar has the characteristics that energy resources are saved, the construction cost is reduced, the requirement for environmental friendliness is met, and mortar waste and labor waste are avoided.

Description

A kind of construction method of dry-mixed mortar

Technical field

The invention belongs to building field, particularly a kind of construction method of dry-mixed mortar.

Background technology

Dry-mixed mortar be in building trade for masonry panel or whitewash the conventional a kind of construction material of metope, mostly adopt cement, sand, and for adapting to the additive composition that different application is added; Dry-mixed mortar is being applied in work progress, various part is needed to sieve, mixing, add water stirring, thus form the pasty mixture with certain fluidity reaching instructions for use, due to a large amount of dust can be produced in process, certain pollution can be caused to environment, thus by the produced on-site of government's restriction dry-mixed mortar; In order to adapt to the requirement of environmental protection, dry-mixed mortar is placed on the dry-mixed mortar producer professional production of specialty, is made into finished product, is transported to construction site, directly use; At present, have two kinds as the dry-mixed mortar of supply of commodities, a kind of adding water is stirred, and also claims wet mortar; A kind ofly to mix but the stirring that do not add water, also claim dry mortar; From most of service condition, there is following defect in these two kinds of Supply Methods, first respectively, wet mortar is transported to construction site after mortar manufacturer production, there is the unmatched problem of labour, because the current construction for mortar is all artificial construction mostly, such as build a wall, wipe one's face; To grow standing time due to mortar and can condense and the characteristic that lost efficacy, if the amount that producer transports is large, has then manually cannotd be used up and will cause waste because solidifying; If the amount that producer transports is little, then construction worker can be caused to leave unused, cause equally and delay project progress and lost labor, because mortar workmen and other work posts are not easy to allocate; And dry mortar is Site, can meet and use how many how much stirring, but, in the production process of dry mortar, the chief component of dry-mixed mortar i.e. sand, can use after needing oven dry, the oven dry of sand, need to consume a large amount of energy, cause secondary environmental pollution simultaneously, the production cost of mortar manufacturer is significantly increased, and unit in charge of construction so that construction investment unit are just married again in these increases, and building cost is increased.

Summary of the invention

For the above defect that the construction method of existing dry-mixed mortar exists, the present invention proposes a kind of construction method of dry-mixed mortar, it is characterized in that: comprise the following steps, and 1, the sand of dry-mixed mortar need not be dried independent supply; 2, other parts except sand of dry-mixed mortar are become cement admixture finished product in dry-mixed mortar manufacturer production; 3, sand and cement admixture are transported to construction site respectively and store; 4, airtight blast system is adopted respectively sand and other component mixtures to be transported to construction working face; 5, in construction working face, both mixing and water addings are stirred, form the wet mortar meeting instructions for use.Described step 1 adopts commodity sand, do not need to dry and secondary operations; Described step 2 is that additive processes in mortar factory according to construction requirement, and proportionally mixes, and packs separately or store transport as finished product by other components such as cement except sand of dry-mixed mortar; Described step 3 increases a set of storage tank in traditional mortar supply system, to store sand and other mixtures respectively; Described step 4 is that induction system is overlapped in employing two, by different blast systems respectively to construction working face transport of sand and other mixtures; At the end of blast system, there is airtight blender, two kinds of article proportionally can be mixed automatically, and join in mixer; Described step 5 on construction working face, installs mixer and the automatic stirring that proportionally adds water, to supply the workmen needing mortar on construction working face.

Beneficial effect

Beneficial effect of the present invention is, saves the energy, reduces building cost, meets environmental requirement, avoid mortar and artificial waste.

Detailed description of the invention

Now in conjunction with detailed description of the invention, further illustrate technical scheme of the present invention; Commodity sand is directly transported to construction site, is stored in sand holding vessel, cement and additive are produced in dry-mixed mortar factory, the cement admixture finished product after production is transported to construction site, and is stored in another holding vessel; Holding vessel is herein the conventional powder in construction site or pellet object storing tank, is usually used for storing bulk cement, mortar etc.; Two kinds of article are now independently, and it is that the prime cost that finished product dry-mixed mortar is produced consumes source that sand is dried, and sand need not be dried, and saves the energy and producing cost; Dry-mixed mortar producer only stores with by after cement and additive mixing or packs and can meet instructions for use; By the below of holding vessel, connect airtight blast system respectively, respectively by sand and cement admixture, be transported to construction working face, closed conveying system comprises roots blower, loader, conveyance conduit, loading head; Loading head is arranged in construction working face, bi-material two loading heads, and the loading head in this example is cyclone type loading head; Just export from two loading heads and connect blender, when needing to use dry-mixed mortar in construction, sand in two loading heads and cement admixture are proportionally sent into blender, mixer is sent into after blender mixing, add water stirring in mixer, just define the dry-mixed mortar meeting instructions for use, according to number and the workload of workmen, coordinate the dry-mixed mortar stirring respective numbers, excessive is formationed that so there is not dry-mixed mortar is wasted, or affects construction speed because of the quantity not sufficient of dry-mixed mortar; And due to course of conveying be all airtight, there is no again the produced on-site process of sand and cement admixture simultaneously, can environmental requirement be met.

Claims (1)

1. a construction method for dry-mixed mortar, is characterized in that: comprise the following steps, 1, the sand of dry-mixed mortar need not be dried independent supply; 2, other parts except sand of dry-mixed mortar are become cement admixture finished product in dry-mixed mortar manufacturer production; 3, sand and cement admixture are transported to construction site respectively and store; 4, airtight blast system is adopted respectively sand and other component mixtures to be transported to construction working face; 5, in construction working face, both mixing and water addings are stirred, form the wet mortar meeting instructions for use.
