Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

According to an embodiment of the present disclosure, as shown in fig. 1, a mirror concrete terrace glazing process is provided, the glazing process includes step 101, an aluminum hollow light-receiving shoe is worn to enter a construction surface, since the specially-made light-receiving shoe is larger than a common rain boot, the contact area with the construction surface can be increased, the pressure acting on the construction surface is reduced, and a footprint mark is not easily left on the construction surface; the glazing process also comprises a step 102 of carrying out mechanical steamed bread operation and carrying out trowelling and pulp lifting on the ground; after step 102, there is also step 103 of surface finish, which may include performing a previous multiple of surface finishes with metal blades and a final surface finish with a replacement plastic blade. The powder polishing process provided by the disclosure is not only suitable for mirror surface concrete terraces, but also can be used for cement-based type terraces, wear-resistant terraces and the like.

Through above-mentioned technical scheme, when operating personnel worn aluminium system fretwork to receive light shoes and step on the concrete, the aluminium system fretwork is received the contact surface of light shoes and concrete and is far greater than the contact surface of traditional rain shoes and concrete, so, when operating personnel worn special system aluminium system fretwork to receive light shoes and compare and wear traditional rain shoes, when the concrete surface walking of the same initial setting condition, the footprint of stepping on is shallower, and the easier flattening is difficult to leave the vestige of footprint. Aluminum is lighter than other metals and therefore also further reduces the depth of the footprint. The surface glazing operation is carried out after the mechanical troweling operation, if the metal blade is used for glazing in the whole process, the ground is very easy to be scratched, and the flatness of the ground is influenced, so that after the metal blade is used for primarily glazing the ground, a soft blade is needed for finally glazing the ground. Through a large number of experiments, the blade made of high-density ceramic, rubber, carbon fiber, plastic and the like is customized, and finally, the fact that only the plastic material can achieve an ideal effect is found, and the plastic material is harder than the rubber and the like, so that the situation that powder cannot move is avoided; meanwhile, the hardness of the plastic blade is softer than that of the metal blade, so that a finished surface with good pollen gloss is not easy to scrape, the finished surface is more compact, and the ground flatness is higher.

Further, in step 103, namely the surface polishing step, the polishing angle of the metal blade is between 0 ° and 45 °, as the polishing time goes, the moisture on the ground gradually evaporates, the hardness increases, when the polishing angle is small, the ground cannot be driven, and when the polishing angle is too large, the contact surface is too small, and the ground is prone to pothole, so that the polishing angle of the metal blade gradually increases as the hardness of the ground gradually increases within the range of 0 ° to 45 °, and in the surface polishing step, the included angle between the metal blade and the ground is 45 ° at most.

Further, the aluminum hollowed-out light-receiving shoes mentioned in step 101 may include a sole, an arc-shaped cofferdam and a lace connected to one side of the arc-shaped cofferdam, and the sole may be formed by a plurality of diamond-shaped hollowed-out structures, the hollowed-out structures are designed to increase the friction between the foot and the light-receiving shoes, and the hollowed-out structures are made of less material, so that the weight of the light-receiving shoes can be effectively reduced, and the depth of foot prints can be reduced. Simultaneously, the other end of frenulum is provided with the buckle that is used for with the opposite side looks joint of arc cofferdam, and the effect of frenulum and buckle is fixed the foot on receiving smooth shoes, does not take place unnecessary skew when guaranteeing the construction operation to cause unnecessary footprint to ground. The number of frenulum can be one or many, and this disclosure does not limit this, can satisfy different operation personnel's operation requirement according to the length adjustment frenulum of the length of different operation personnel feet.

According to one embodiment of the present disclosure, as shown in fig. 2, the step of performing the mechanical crushing operation includes removing 201 the laitance for disrupting the laitance layer on the concrete surface. When the surface laitance layer is destroyed, step 202 is performed, the wear-resistant material is spread, the spreading of the wear-resistant material is performed in a plurality of times, and the wear-resistant material is divided into three parts according to the size of the required polished floor, wherein each part is 1.7kg/m²-2.0kg/m²Uniformly spreading two parts of wear-resistant materials on the surface of the concrete in the initial setting stage to finish the first spreading operation; after the wear-resistant material absorbs moisture, the ground is changed from white to dark gray, and the mechanical trowel operation with the disc is carried out again; and then, after the wear-resistant material is hardened until the ground can not collapse visually after being stepped on by an operator, uniformly spreading the last part of wear-resistant material on the surface of the concrete, and finishing the second material spreading operation. After the spreading operation is finished, step 203 is carried out, the leveling operation is carried out, namely, the mechanical trowel operation with the disk added for the second time and the mechanical trowel operation without the disk added for a plurality of times are carried out, and the mechanical trowel operation needs to be carried out in a longitudinally and transversely staggered mode. The wear-resistant material may be emery or other composite organic material (such as polymer polytetrafluoroethylene), which is not limited in this disclosure.

Further, in step 201, namely, the step of removing the laitance, the laitance of the concrete surface portion is scraped off by using an aluminum ruler, and in the embodiment of the present disclosure, the aluminum ruler is an aluminum ruler with adjustable flatness. After the surface laitance goes out, adopt the mechanical float who installs wooden or steel disc additional to destroy the laitance layer at concrete mirror surface terrace corner position.

Further, in the process of polishing, the concrete setting speed is not consistent, if the concrete is directly sprayed, the finished surface is color-different due to the change of the water-cement ratio, so in steps 202 and 203, that is, when the operator is spreading the wear-resistant material and performing the polishing operation, if the wear-resistant material has insufficient moisture absorption, that is, the ground surface cannot be completely changed into dark gray, the electric sprayer can be used to spray the light-receiving synergist in the form of mist to the construction surface lacking moisture. The light-harvesting synergist is sprayed on the surface of concrete in a mist form when the concrete or the wear-resistant material is lack of moisture, slurry is easily lifted during the powder coating construction after the light-harvesting synergist is sprayed, the color difference possibly generated by changing the proportion of water and the concrete is reduced to the greatest extent, and the probability of surface cracking is reduced.

Further, the light-receiving synergist comprises silicon dioxide, and the silicon dioxide is in a colloidal state. The colloidal silicon dioxide has a large specific surface area (specific surface area/particle volume), so the colloidal silicon dioxide has strong adsorption capacity, and can adsorb ions in concrete slurry after penetrating into the concrete, and crystals are generated to fill gaps of a concrete structure, so that the final polishing effect of the concrete ground is improved, and the ground is bright and flat.

Further, in step 203, the mechanical trowel operation without the disk is performed at least three times based on the data obtained through a large number of actual operations during the polishing operation, so that the ground flatness can achieve the required effect, and the foundation is provided for the subsequent polishing operation.

According to one embodiment of the present disclosure, in step 103, i.e., the surface polishing step, the main body surface polishing is performed by using the steering type double-disk machine with the metal blade, and since there are dead corners at the corners and a large amount of machines cannot be polished, the surface polishing work at the corners can be performed by using the hand-held machine trowel or the hand-held scraper, and the surface polishing can be performed more comprehensively.

Furthermore, data accumulated through a large number of actual operations are obtained, and the surface concrete can be smoother and finer only by using the plastic blade for the surface glazing times of more than or equal to 5 times, so that the ground flatness and the attractiveness are improved, and the required effect is achieved.

The preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings, however, the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present disclosure within the technical idea of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.
