Description
Technical Field
The utility model relates to a quick construction equipment of mortar. Is applicable to the technical field of mortar construction devices.
Background
With the deep development of the manufacturing industry in China, the manufacturing industry in China is gradually developed into the creation industry in China, wherein the construction industry also obtains good development achievements, and the construction efficiency problem is an aspect of thinking and effort, especially a large-scale project, which is always unconscious by technicians, and particularly needs to be implemented by high-efficiency and high-quality process equipment. In the later stage of the project, external decoration and installation beautifying links are required, and mortar coating is an indispensable process generally.
In the mortar smearing construction process, after necessary steps of polishing, cleaning and wetting the foundation are completed, mortar distribution and smearing construction are required. In the mortar feeding (distributing) mode, the vertical surface, the inclined surface, the inverted suspension surface and the plane have larger differences, and the scraping and distributing, the throwing and distributing, the spraying and distributing, the plastering machine and the like are summarized.
Scraping and smearing cloth: the most commonly used mortar distributing mode generally adopts manual multi-frequency scraping operation, namely, a small amount of mortar is dug on the mortar knife, and the plastering is pressed on a wall body by the plastering knife, so that the construction thickness, the flatness and the efficiency generally depend on the proficiency, the physical ability and the technical level of workers.
However, in the face of a large amount of construction needs, skilled workers are only relied on, and technical workers cannot bring in the technical workers, in other words, a plurality of different workers hardly meet the high-quality engineering quality requirements, and the main defect is that the construction quality is not high in consistency, a plastering layer must be firmly bonded according to the regulation of 'quality acceptance criteria for architectural decoration and finishing engineering', delamination hollowing and cracks should not exist, and when the single-sided wall body with the thickness less than 5 square meters is adopted in the house construction for single plastering construction quality inspection, the hollowing at 1 position is allowed, and the hollowing area is not more than 5 square centimeters; the single-sided wall body with the area larger than 5 square meters allows 2 hollow drums at most, and the area of each hollow drum is not larger than 5 square centimeters. The occurrence of the hollowing in the super-area is also common, and is a link of self-checking before acceptance inspection, which causes unnecessary waste. The reason is that, except that the mortar construction process is not standard (different from person to person), it is difficult to quantify various parameters, such as the angle, force, area, quantity and the like of a spatula, and the main defects are as follows: the construction area of single scraping is small, the problem of more boundary overlapping exists, and cracks are usually from the overlapping part; in the process of plastering and pressing mortar, the mortar forms extrusion sliding movement on the foundation surface, the water of the mortar is locally absorbed by the concrete foundation surface, and the absorbed amounts are inconsistent, so that the mortar on the base surface has different dryness and humidity and forms quality difference; quality differences are generated in the construction process under the influences of different heights of the wall surface, different time and fatigue of people, and differences can be generated on the mortar bonding surface due to the fact that manipulations are changed carelessly at any time.
Throwing and throwing cloth: because the hollowing and cracking problems easily occur in the conventional mortar scraping construction, the slurry throwing construction process is provided, the artificial quality influence factors during the conventional mortar scraping construction are basically solved, and the main process generally comprises the following steps: base course treatment → base course acceptance → watering and wetting → mortar preparation → field slurry throwing. Some projects are made of square multilayer fine iron wires with the size of a badminton racket surface, the badminton racket surface is fixed at one end of the tool through a stick, a proper amount of mortar is scraped on the racket surface, the racket is manually swung to a wall surface, the mortar is hammered to the wall surface under the action of gravity to form adhesion, the process of putting the mortar on the wall is completed, and the process is repeated to form a complete mortar surface. In some projects, mortar is grabbed by hands and thrown to a wall surface for construction, particularly an inverted suspension surface of a floor slab, and blank parts of the wall body are continuously thrown to realize bonding.
The mortar which is hammered on the wall surface has certain strength, can deeply fill small holes of a concrete base surface, instantaneously completes the extrusion effect, and has certain mortar spraying effect. The method has the main defects of low efficiency, non-continuity, large loss, easy occurrence of the problems of local white exposure and excessive mortar overlapping and is not suitable for large-area construction.
And (3) cloth spraying: the sprayed concrete/mortar construction process is generally used for construction of side slopes, tunnels and walls, a mortar pumping machine and a matched high-pressure air pipe are usually needed to form a sprayed construction system, mortar is quickly blown away and hit the walls under the drive of high-speed air flow, a quick and continuous construction process is realized, the human influence factor of hollowing and cracking of the mortar is basically solved, the construction quality is greatly improved, and a certain industrial chain is formed at present.
The pipeline is adopted to convey the mortar, so that certain requirements are required on the pumping performance of the mortar, the spraying construction of the mortar with high viscosity cannot be carried out, and the unit with small area is not suitable for being adopted because the equipment is cleaned and the fixed loss generated by stirring the mortar is large.
Material distribution of a plastering machine (wall plastering machine): be applicable to the facade construction of rule, the plastering machine is from taking the feed bin, on the wall that suitably handles through the base face, can accomplish cloth and the step of floating fast from bottom to top, and the operation of plastering of removal base continuation next breadth is different according to the machine model, once accomplishes width 1 to 2 meters and varies, is the present building trade, and the better selection of quick high efficiency construction of plastering.
The utility model discloses of plastering machine does bring very big facility for facade mortar construction, but its construction that can't accomplish top surface, inclined plane, arc surface also can't be under construction to the basement root, also can't realize effective construction operation to super high facade.
The above mortar construction process methods have many construction projects in use, the applicable project conditions of each method are different, relatively speaking, the spraying construction method has strong universality and high bonding reliability, can meet most project requirements, but also has the problems of strict requirements on mortar consistency and large mortar loss. With the advance of engineering construction, common cement mortar cannot be applied to more and more working conditions, so that special mortar materials are gradually adopted in engineering to meet engineering requirements, such as high-fiber parameter elastic concrete/mortar and high-viscosity epoxy resin concrete/mortar, the most traditional scraping and plastering construction is mainly adopted at present, and the engineering construction requirements of a large area are difficult to meet.
