Description

Roller type coating retarder elastic modeling mold

Technical Field

The utility model belongs to the technical field of concrete molds, relates to a roller-type coating retarder elastic modeling mold, and in particular relates to a functional elastic modeling mold for producing prefabricated exposed bone material decorative concrete, wherein the surface of the roller-type coating retarder is provided with decorative modeling patterns.

Background

The concrete is made up by mixing natural river, sea pebble or gravel with cement and water according to a certain proportion, pouring them on the surface of mould with negative retarder, after demoulding of the whole concrete member, flushing the surface coated with negative retarder by high-pressure water gun to expose the original appearance of stone, and it is similar to the water stone brushing technique popular in 70-80 years. The exposed aggregate decorative concrete has various colors and shapes as raw materials, can decorate patterns with various shapes and designs, is widely applied to indoor decoration and outdoor landscape modeling, and also adopts exposed aggregate decorative concrete for large-area outer wall decoration, thereby showing natural and pure feeling. Along with the progress of the scientific and technological level, people not only pursue the effect of exposing aggregate concrete on the whole wall body, but also combine plain surfaces with exposed bone material surfaces and even make artistic patterns on the exposed bone material surfaces, so that the construction difficulty is greatly increased.

At present, the traditional aggregate concrete manufacturing process mainly adopts a hairbrush scraping or manual hand washing mode in the process of waiting for concrete setting and hardening manually, so that aggregates in the concrete are exposed, the mode is more in manual participation and can only reach the whole aggregate exposure, the depth of aggregate scrubbing is difficult to control, and the wall surface of the aggregate exposure artistic pattern is difficult to manufacture.

Specifically, the traditional construction process of exposed aggregate decorative concrete generally comprises the following steps: (1) In the cast-in-situ process, stone aggregates with different colors are mixed into cement, sand and a certain amount of water are stirred, and the mixture is poured into a fixed mould after the stirring is completed. (2) And after pouring, the template is removed at fixed time, and the surface cement slurry is removed before the concrete is completely coagulated and hardened, so that aggregates such as stones and the like in the concrete are exposed. (3) The artistic modeling is made at the required position through a simple perforated wood die or other material dies, so that the exposed material surface and plain concrete combined part of the wall surface is produced. The above process generally suffers from several problems: (1) For general projects only can be used for cast-in-place concrete, and cannot be used for factory prefabrication, for projects with large aggregate decoration areas, the project period can be greatly increased, so that the measure cost and the management cost are greatly increased, and the construction efficiency is low. (2) The effect of exposing the aggregate on the surface can only be controlled by the proficiency of workers, which is extremely unfavorable for the whole quality control of the whole project, and the coagulation hardening time of concrete in different batches is different, so that the problems of different depths of the exposed aggregate and surface color difference which greatly influences the decoration effect are caused. (3) Because only a simple hollowed-out template is used for positioning on the wall surface, for the project with artistic modeling requirements, only a simple and old exposed bone material pattern can be made, and the modern design requirements cannot be met. The exposed bone material project requiring complex artistic patterns can only be considered to adopt modes of poor durability such as pictures or sculptures and serious construction environment pollution, and the decorative effect can not reach a higher level yet.
