Fig. 1 shows a construction method in an example of the present application.
Detailed Description
In the field of construction, some existing construction robots can only perform some relatively standard construction operations. For the construction requirements of some complex operations, manual intervention is also required at present.
For example, in a scene where wall construction is performed and local or regional protection is required, the current operation requires human intervention.
One common existing construction method is as follows:
traditionally, a plastic film is stuck on a protected finished product in a manual mode for protection, and then an outer wall is operated. Because the operation mode robot of pad pasting realizes the degree of difficulty height, need make the workman take the hanging flower basket to go aluminum alloy window position and paste the plastic film. The manual high-altitude operation has certain safety risk, the consistency of the quality of the plastic film is poor, and the adhered plastic film is easy to be damaged or uncovered under the influence of the environment (such as wind). After the construction is finished, the stripping needs to be manually carried out by relying on the hanging basket to reach the position of the aluminum alloy window again, and the aluminum alloy window is manually torn off. Moreover, the manner of tearing off the plastic film is easy to leave glue residues on the protected finished product, and meanwhile, the manner is difficult to be completed by full-automatic mechanical equipment.
As mentioned above, wall surface construction requiring protection is currently performed by means of a film. The film can be mechanically applied, but when the protection area is a profile, the film is mechanically applied with great difficulty and may be difficult to implement. Furthermore, the subsequent operation of removing the film after the construction is difficult to be carried out by mechanical equipment. Or the attached film is not long enough to be easily damaged or uncovered by wind, for example, in order to facilitate manual or robotic stripping. Therefore, the current scheme often requires a large amount of manual intervention, so that the construction period is long, the cost is higher, and the like.
The invention provides a finished product protection technology and a construction technology which are suitable for being completed by a robot in a full-automatic way; the whole operation process can be carried out without manual participation. In the application example, the inventor provides a finished product protection technology suitable for being completed by a robot in a full-automatic mode, and a construction scheme without manual participation is adopted in the whole operation process. It should be noted that the process of the present example may also be performed manually. Compared with the related scheme of the current manual film pasting, the scheme of the application example can still achieve relatively better effects such as small manual operation difficulty, low strength, short construction period and the like even if the scheme is implemented manually.
As mentioned above, the current wall construction protection scheme is to apply a prefabricated protection film to an area to be protected, and then perform construction (such as plastering). And after the construction is finished, the film is lifted. In contrast, in the present application example, the film is not applied with a prefabricated film, but is selectively applied by a fluid material to form a film on the surface of the protection area. And then, construction is carried out, and the film is removed after the construction is finished. And, in particular, the film-forming material selected in the examples is one that can be easily removed after its adhesion to the protection area is reduced by an appropriate operation (for example, a non-destructive manner).
In the above aspect exemplified in the present application, since the film is formed on the surface of the protection region by the fluid material, the fluid film formation is easily performed, and can be applied to various profile members. Meanwhile, the material can also conveniently reduce the adhesion force after film forming, thereby avoiding the dilemma that the existing film pasting difficulty is high, the film uncovering difficulty is high, the glue is remained and the like.
More importantly, the film formation of the fluid material described above, as well as the reduction of the adhesion of the film to the protected area and the removal of the film, exemplified herein, are easily performed by mechanical means. Therefore, the construction scheme of the application example is a construction scheme which is suitable for being completed by a robot in a full-automatic mode, and the finished product can be protected without manual participation in the whole operation process.
Because the construction difficulty of the outer vertical surface, especially the high-rise building, is large and the risk is high, the construction has better prospect and advantage through automatic machinery. Therefore, the scheme of the application example is particularly suitable for the construction of the outer wall surface of a high-rise building. Of course, the scheme of the application can be used on other non-wall surfaces, such as the ground or inclined facades. Moreover, the exemplary embodiments of the present disclosure are equally applicable to cases where the protected area and the construction area are adjacent (either immediately adjacent or marginally contiguous) as well as non-adjacent.
The construction scheme in the examples will be described in detail below.
The construction method comprises the following steps:
step S101, at a construction site where a construction area and a protection area are determined, transferring and curing a fluid material to the protection area to form a temporary protection layer attached to a surface of the protection area.
The construction area and the protection area can be different according to the requirements of a construction site.
For example, a job site may be a variety of wall surfaces — illustratively, a wall facade or a wall interior facade, or a non-wall facade, or a tilt-up wall surface. Accordingly, the construction area and the protection area may be different areas of the wall surface, or different building elements on the wall surface. For example, the protected area is a window and the construction area is a wall with a wall surface outside the window.
Alternatively, in still other examples, the job site is the ground. In these examples, the construction area is a specific building element of the ground, and the protection area is the ground or a specific building of the ground outside the aforementioned specific building element, and the like.
Alternatively, in other examples, the job site is a combination of wall and floor. In these examples, the construction area is a wall surface or a specific building member of the wall surface, and the protection area is a ground surface or a specific building of the ground surface, and the like.
Further, the construction area and the protection area may be identified and determined at the time of work by a machine or a human at the construction site. Alternatively, the construction area and the protection area may be previously designated manually or mechanically, and then the identification tag or the marker may be set, and then the machine on the construction site may identify the tag or the marker during the operation (for example, image recognition) and confirm the tag or the marker.
After the construction area and the protection area have been determined, the fluid material is transferred in a convenient manner. For example, the fluid material may be transferred to the protected area by spraying or knife coating or spin or roller coating. The specific transfer mode can be determined according to the appearance shape of the protection area. For example, for a structural member with regular surface topography, such as a flat glass plate, a fluid material or slurry can be formed into a wet film (cover layer) on the surface by knife coating or spraying. And for the special-shaped component, the various surfaces of the special-shaped component can be conveniently and effectively shielded and covered by spraying to form a film-wet film (covering layer).
For a continuous protection area, the cover layer is continuous. Whereas for a plurality of spaced apart protective areas the cover layer is discontinuous (discrete). For example, when the protected area is a window, the cover layer may be a continuous film. When the protective area is a plurality of windows dispersed at different locations on the wall, the corresponding covering is continuous for any individual window, while the covering from the plurality of windows is dispersed as a whole.
In addition, after the fluid material is transferred to the surface of the protected area, in order to prevent the fluid material from being separated from the protected area or from being easily damaged, the wet film is selectively cured to form a temporary protective layer (e.g., dry film/cured film/solid film) having a protective effect. The curing mode can be realized differently according to different fluid materials. For example, the curing may be performed by volatilizing a dispersion in the slurry. Accordingly, the dispersion may be volatilized by irradiation with light, or heating, or a combination of irradiation with light and heating. Alternatively, in other examples, the method of curing includes chemically reacting the slurry to cure. Wherein the reacting of the slurry may be by thermal excitation or by illumination of a specific wavelength.
The fluid material may be any commercially available material, and the present application is not limited thereto. Typically, the fluid material may be a commercially available temporary protective coating, or a water washable temporary protective coating, or a peelable coating. Alternatively, the fluid material is a water-washable temporary protective material capable of being de-filmed by water washing.
Illustratively, the fluid material may be a mixture of a glycerol oligomer and a water-dispersible polyurethane. Alternatively, the fluid material may be the material described in "temporary protective coating for washable (aging and application of synthetic material, vol.46, No. 5, 2017). Alternatively, the fluid material may be the material described in the Chinese patent application (application publication No. CN105038401A) (hereinafter referred to as an example material).
Applications of the above "example materials" are found below.
The example material (water washable temporary protective paint) was roll coated on four windows of the same specification using a roller. The roll coating amount for each window was as follows: 0.056Kg/m2、0.12Kg/m2、0.2Kg/m2、0.255Kg/m2. After roller coating, the window is exposed to the sun for curing for 4 h. Then, the windows are respectively coated with emulsion paint (firstly) and sprayed with multi-color paint (secondly) -the simulation robot is sprayed with paint overspray. Through the operation, each window sequentially comprises a washable temporary protection coating layer at the bottom, a latex paint layer positioned on the middle layer and a colorful paint layer positioned on the latex paint layer at the top layer.
After the roller coating and spraying were completed, curing was performed for 2 hours, followed by further testing. The test result shows that: the temporary protective coating and the latex paint and colorful paint attached on the temporary protective coating can be easily washed away.
In addition, different formulations of fluid materials may be provided depending on the protective zone or mode of operation. For example, the fluid material is a water washable temporary protective material suitable for aluminum alloy windows and tile facings. In some examples, the protective material is prepared from two formulas of high viscosity and low viscosity, and the high-viscosity protective material is suitable for being sprayed on the surfaces of aluminum alloy windows and tiles by a robot; the low-viscosity protective material is suitable for being brushed on the surfaces of aluminum alloy windows and tiles by a robot roller. The protective film can be formed on the surfaces of aluminum alloy windows and tiles in a period of time by the protective materials with the two formulas.
Further, it is considered that the temporary protection layer may be intentionally or unintentionally contaminated with dirt or the like during construction in the temporary protection process. Therefore, in some examples, the particulate matter may be added to the fluid material as described above. When particulate matter is already present in the fluid material, it may be advantageous for the particle size of the incorporated particles to be larger than the particle size of the original particles.
This is because the doped particles may cause the surface of the temporary protective layer to have protrusions. These protrusions cause the surface of the temporary protective layer to assume a rugged structure. That is, the fluid material contains particles, and the temporary protective layer has a rough surface formed by the particles protruding. Then, when the dirt adheres to the surface of the temporary protective layer, the incorporated particles prevent the dirt from forming a film. I.e., the film of contaminant formation is pierced by the incorporated particles (which may advantageously be angular or suitably sharp) to expose the inner temporary protective layer. This facilitates the subsequent reduction of adhesion between the temporary protection layer and the protected area and the implementation of the removal operation.
And S102, constructing at least a construction area.
After the protected area is protected in step S101, various required construction and work operations can be performed on the construction area. For example, wall object installation, wall cleaning, or plastering, putty, paint, etc.
Note that, when the construction area is constructed in this step, the protected area may be constructed. For example, if the construction of the construction area is plastering, the plastering may be performed on the protected area. Namely, in the construction, the plastering construction is carried out on the protection area and the construction area without avoiding the protection area (or the protected finished product).
This is because, in the scheme exemplified in the present application, the object that needs to be protected has already been protected using the temporary protection layer. Therefore, the work is performed on the protective region at this time, and substantially on the temporary protective layer (the work film formed on the protective region temporary protective layer). In the latter stage or step S103 described below, the temporary protective layer may be removed together with the application film in the protective region attached to the temporary protective layer.
Therefore, the advantages of the scheme of the application example can be embodied, namely after the protection area is protected, when construction operation is carried out, the protection area or a protection finished product does not need to be avoided deliberately, a constructor or a construction robot can carry out construction operation on the whole wall surface, or the whole protection area and the construction area, so that the operation difficulty and the complexity of the protection area and the construction area which need to be treated differently during construction are greatly reduced, and the construction efficiency is also improved.
Step S103, after the adhesion force of the temporary protection layer and the protection area is reduced by using a liquid soaking and/or heat treatment mode, the temporary protection layer is removed.
After the construction of step S102 is completed, this step is performed to remove the temporary protective layer. In the application example, the membrane removal is carried out in a step-by-step mode; or the operation of removing the film involves two processes. That is, the adhesion between the temporary protective layer and the protective area is decreased and then removed.
The adhesion is reduced, for example, by wetting with a liquid (to wet the film), or by heat treatment, or by both wetting and heat treatment, to reduce the adhesion of the temporary protective layer to the protective area. Wherein the liquid is provided in an atomized state or in a droplet state. Namely, the liquid can be contacted with the temporary protective layer by spraying or dripping; the liquid used will vary depending on the fluid material. The liquid may be selected from water based on cost, environmental protection, and convenience and safety of operation; accordingly, the fluid material, in combination therewith, is a temporary protective material for the water-washable film.
After the adhesion of the temporary protective layer to the protection area is reduced, it can be easily removed by hand or machine. Such as manually lifted or scraped off, etc. Or by mechanically spraying a high-pressure water stream or a gas stream or a liquid stream onto the temporary protective layer whose adhesion has decreased, or by scraping it off by a roller brush, or by washing it off by high-pressure water stream impact in the process of scraping it off by a roller brush.
In other words, after the construction is finished, the protective film formed by the washable temporary protective material and mortar, putty, paint and the like adhered on the protective film can be removed automatically by a robot. For example, the robot sprays atomized water or water drops on the surface of a protected finished product, and after the protective film is wet, the protective film can be easily removed by flushing with water with higher water pressure or by a roller brush or by combining flushing with the roller brush.
So far, the construction scheme of the example of the present application has been clearly and completely stated, and in order to facilitate the implementation of the scheme of the example of the present application by those skilled in the art, the example also provides a wall surface construction system for implementing the foregoing construction method.
The system comprises a film laminating mechanism, an operating mechanism and a film stripping mechanism which are independently configured and operate in a matched mode. Further, according to the functional design, the film coating mechanism, the operation mechanism and the film removing mechanism can be integrated into one device.
In addition, for scenes with high-altitude operation requirements, the system can be provided with a movement mechanism which is used for correspondingly moving selected equipment (such as a film covering mechanism, a working mechanism and a film stripping mechanism) according to requirements. The movement can be vertical lifting, transverse movement or the combination of the two.
In other words, in order to enable work at high altitudes, a traveling mechanism (including a suction cup or the like) or an independent moving mechanism that can move at high altitudes is independently provided for each mechanism in the above-described equipment.
Exemplarily, the movement mechanism comprises a suspension device and a basket, a lifting rope and a winch connected with the suspension device. The hanging basket can be connected with the suspension device through a lifting rope and can be lifted along the outer wall in a winding mode. The film covering mechanism, the operation mechanism and the film removing mechanism can be arranged on the hanging basket.
In other examples, the movement mechanism includes a suspension device, a basket, a hoist rope, and a hoist. The hanging basket can be connected with the suspension device through a lifting rope. And the gondola therein can be climbed along the rope by means of a hoist. The film covering mechanism, the operation mechanism and the film removing mechanism can be arranged on the hanging basket.
The above-mentioned mechanisms may be operated independently by manual operation or may be controlled by an automatic control device. And the automation control device can be matched with each mechanism in a communication way through a wired communication cable or a wireless way (such as one or a combination of more of infrared rays, NFC, WIFI and Bluetooth). The automatic control equipment is provided with a controller which is used for correspondingly controlling different equipment to operate according to an operation instruction. The controller may be, for example, various electronic components or a collection of electronic components capable of certain data storage and processing. For example, a Central Processing Unit (CPU), a Micro Control Unit (MCU), an editable logic controller (PLC), a Programmable Automation Controller (PAC), an industrial control computer (IPC), a Field-Programmable Gate Array (FPGA), an Application Specific Integrated Circuit chip (ASIC chip), and the like.
The film coating mechanism is used for arranging a temporary protective layer by using a fluid material in a protective area.
In order to be able to provide the temporary protective layer with the fluid material, the film covering mechanism has a transfer device that performs a fluid material transfer operation. The transfer device is used to transfer the fluid material to the protective area to form a cover layer and, after curing, to form a temporary protective layer.
The transfer device in the different examples has different configurations, for example, the transfer device comprises a nozzle for producing the cover layer by spraying; alternatively, the transfer device has a roll for producing the cover layer by means of roll coating. When the covering layer can be cured under natural conditions, the film coating mechanism can be selected not to use a curing device. In other examples, the coating mechanism may be configured with corresponding devices in order to speed up or for material reasons when additional curing devices are required. For example, if the cover layer is to be cured by heating, the coating mechanism may be provided with a heating device to enable the cover layer to be cured by chemical reaction or by evaporation of the dispersing agent. The heating device is, for example, a hot air heater, and heats the target object by jetting hot air in a directional manner.
The operation mechanism is used for executing a preset construction task in a construction area of the wall surface. The operation mechanism can have different implementation modes according to different operation contents. For example, the work content is wall cleaning, wall plastering, wall putty coating, wall window installation, wall drilling, etc. Therefore, for example, when the operation content is the spraying operation of the outer wall surface, the operation mechanism can be configured with the spray head for spraying operation of colorful paint, emulsion paint, stone paint and the like of the outer wall, and the operation form can temporarily protect the window and the like of the outer wall, and the spraying operation efficiency of the outer wall is improved.
The film removing mechanism is used for removing the temporary protection layer from the protection area. As described above, in the present example, the film removal mainly includes two steps and is a step of reducing the adhesion and a step of removing the film, respectively.
Correspondingly, the film stripping mechanism can be provided with a film stripping device and a film stripping device. And the film removing device reduces the adhesion force of the temporary protection layer and the protection area in a liquid soaking and/or heat treatment mode. When the adhesion is required to be reduced by means of liquid infiltration, the film stripping mechanism can be provided with a sprayer for spraying water or other liquids. Alternatively, the film removing mechanism may also be configured with an atomizer for atomizing the liquid. When the adhesion force needs to be reduced by heating, the film stripping device can be provided with a heater. Alternatively, the sprayer (or atomizer) and the heater may be arranged simultaneously and may be operated independently of each other as needed.
The stripping device separates the temporary protection layer from the protection area wholly or dispersedly after the adhesion of the temporary protection layer is reduced. According to the film removing mode, the film removing device can carry out film removing operation through different actuating mechanisms. For example, the stripping device may be provided with a roller brush to remove the film having reduced adhesion from the wall surface by scraping action. Alternatively, the stripping device may be provided with a nozzle which ejects a jet (gas or liquid) to remove the film with reduced adhesion from the wall surface by the impact of the jet. Of course, both may be arranged at the same time and combined to perform the operation.
In brief, in combination with the wall surface construction system described above, the wall surface construction with the need for temporary protection can be performed in the following manner, referring to fig. 1.
T1, moving the outer wall hanging basket type operation robot to the position of a protected finished product (such as an aluminum alloy window) through a hoist or a winch. And then, the cradle type operation robot covers the surface of the protected finished product with a washable temporary protection material by spraying through a spray head or roller coating through a roller.
T2, after a certain time, the water-washable temporary protective material covering the surface of the protected product is solidified to form a protective film. If the curing time needs to be accelerated, hot air can be blown through an air drying device configured by a hanging basket type operation robot so as to heat the repeated covering film, so that the curing is accelerated to form the protective film.
It is noted that in some examples, the water-washable temporary protective material cured into a film has a certain rain-proof capability so as to be able to be directly washed by non-heavy rain without being easily washed away by rain water. Therefore, in construction operation such as external wall spraying for several days, the protective device can cope with severe working conditions such as rainy weather, and can continuously play a protective role.
T3, after the step T2, the wall surface around the aluminum alloy window on the outer wall surface can be constructed by using an outer wall operation robot to carry out normal plastering, putty, paint and the like. And particularly, the protected finished products of aluminum alloy windows and the like on the outer wall surface can also be subjected to normal construction such as plastering, putty, paint and the like. In other words, since the finished product protection has been performed by the coating film, the aforementioned construction product performed thereon can be removed at a later stage. That is, the construction operation does not need to avoid the protected finished product deliberately, and mortar, putty, paint and the like stained on the protective film of the protected finished product can not cause fouling to the protected finished product in the construction process, thereby being very convenient for the operation of an external wall operation robot and avoiding various other finished product protection measures in the construction.
T4, after the construction operation of the outer wall operation robot of the T3, atomized water or water drops can be sprayed on the surface of the protected finished product through the hanging basket type outer wall paint spraying robot. In the step, the protective film is soaked by water, so that the adhesive force of the protective film on the surface of a protected finished product is reduced, and the water consumption and the cleaning difficulty in the subsequent steps are reduced.
T5 cleaning robot cleans the surface of the protected product completely by washing with water or rolling brush or combination of washing and rolling brush with higher water pressure. Because the protective film is soaked in the T4 step by a water spraying mode, the cleaning can be completed only by consuming a small amount of water.

In the present application, conventional equipment, devices, components, etc. are either commercially available or self-made in accordance with the present disclosure.
