Description

Complex detachable box type mould for exposed aggregate floor tile

Technical Field

The utility model relates to an innovative technology for improving the structure of a concrete exposed bone material forming die with retarded local surface, in particular to a technology for improving the disassembly and assembly of a local functional component of a polyurethane rubber die for producing a precast concrete profile with exposed bone material decorative effect only in a local area.

Background

The exposed aggregate veneer has unique charm, fashion trend and space beauty, and the cement concrete exposed aggregate technology has very rapid development compared with the asphalt pavement construction technologies such as color permeable concrete, exposed aggregate and the like.

For example, in the case of sponge city cast-in-situ water permeable landscape road, a color water permeable concrete and exposed bone material paving process is generally adopted. The color concrete is made on the bottom layer of the pavement, and the surface is calendered by exposed bone material to manufacture the prefabricated assembled pavement slab or brick with thorough water permeability.

And the prior art of molding floor tiles with exposed concrete bone material is more widely used. The floor tile decorative concrete product produced by the mould is formed by one-step casting, and has good integrity. In the manufacturing process, compared with the concrete surface without retarder, the concrete surface after retarder spraying can be precisely and quantitatively controlled in a certain range to delay solidification, and after the normal solidification time is preset, the unset concrete surface can be washed by a certain water pressure to expose sand or coarse stone particles. Two major advantages are: 1. the flushing depth is uniform and beautiful; 2. the flushing window period is long, and the flushing can be performed within the range of 18 to 72 hours.

The foregoing concrete open-faced floor tile molding technique, although occurring earlier, is relatively complex and somewhat less mature in its manufacturing process. The main appearance is that; the design effect is very inconvenient to realize according to the conventional template, and particularly, a special decoration aggregate exposure retarder needs to be coated on a die in the aggregate exposure area, so that the retarder is controlled to be coated only in the designated pattern area, the control is very difficult, the time and the labor are wasted, and the mass production is difficult.

For example: the research on the box-type polyurethane rubber mold for prefabricating and producing the local aggregate floor tile shows that the existing traditional polyurethane rubber mold is a whole piece of non-detachable flat plate mold. When used in prefabricated production, one of the following two processing modes is generally adopted, namely:

1) The density board or the multilayer board with the hollowed-out patterns is used, after the positioning is accurate, the density board or the multilayer board is placed on a die flat board for fixing and bonding, and then the decorative retarder is sprayed or brushed, so that a decorative retarder area with the hollowed-out patterns is formed at the hollowed-out position of the surface of the die flat board. Or alternatively;

2) And spraying the decorative retarder on the acrylic plate cut with the decorative pattern, and then bonding the acrylic plate on the die flat plate, so that a decorative retarder area with the pattern is formed at the acrylic plate.

The following problems generally occur in the two ways:

1) When the retarder is sprayed, part of the retarder can be slightly sputtered to adjacent areas outside the edges of the retarding patterns along with air flow, so that the outline of the exposed bone material patterns is unclear, and the finish of the exposed bone material decorative patterns is affected.

2) After the retarder reacts in contact with concrete, the retarder is easy to diffuse and overflow to adjacent areas along with disturbance in the production pouring process, so that the edges of the exposed aggregate are irregular, and the attractiveness of the exposed aggregate decorative pattern is affected.

3) In the spraying process or the production process, once the mold contacts the retarder, the tiny capillary holes on the surface of the mold can possibly adsorb and remain the retarder, and the retarder is difficult to clean, so that in the subsequent production process, slight impression flaws appear on the concrete non-exposed-bone facing, and the decoration effect is affected. Therefore, during the second repeated use, the retarding area can only and must be accurately used at the first fixed position, otherwise, the residual retarder on the mold can affect the decorative effect, but the positioning technology in the prior art is difficult to accurately control.

4) The surface of the area outside the exposed bone material effect is required to be coated with a concrete release agent, if the release agent is firstly coated, the adhesiveness between the retarder and the mold is affected, and if the release agent is later coated, the retarding effect of the retarder is affected by the release agent.
