Description

Technical Field

[0001] The utility model relates to the technical field of building decoration structures, in particular to a pre-treatment structure for the splicing seams of GRC boards. Background Art

[0002] GRC is an advanced composite material, which uses alkali-resistant glass fiber as the reinforcing material and combines with a cement mortar matrix. The GRC decorative boards made of this material have been widely used in the field of building decoration due to their diverse decorative effects, light weight and high strength, and excellent durability, especially in decorative landscape walls and building exterior walls.

[0003] The prior art has the following problems:

[0004] Generally, decorative dividing strips are included in the design of GRC boards to enhance the visual effect.

[0005] As Figure 1 shown, in the existing treatment method one, decorative dividing strips 2 are pre-cut on the GRC board 1, and then secondary grinding is carried out at the splicing seam 3 of adjacent GRC boards 1 to ensure the style consistency with the dividing strips 2. This process not only increases the working procedures, but also is more difficult to control the grinding quality, and it is difficult to ensure a good decorative effect.

[0006] As Figure 2 shown, in the existing treatment method two, real stone paint 4 is sprayed on the bottom plate of the GRC board 1 and dividing strips are added, but this method is prone to cracks during the film-forming process, and after being exposed to the sun for a long time, the real stone paint coating may turn yellow.

[0007] In view of these problems, the technicians in this technical field are committed to developing a new pre-treatment method for the splicing seams of GRC boards to solve the connection problem of the splicing seams of GRC boards with decorative dividing strips.

[0008] The aim is to solve the connection problem at the splicing seams of GRC boards with decorative dividing strips to improve the construction efficiency and the final decorative effect.

[0009] Therefore, how to design the structure of the splicing seams of GRC boards to improve the assembly efficiency of GRC boards and ensure the decorative effect has become an urgent technical problem to be solved by the technicians in this field. Summary of the Utility Model

[0010] In view of the above-mentioned defects of the prior art, the utility model provides a pre-treatment structure for the splicing seams of GRC boards, and the achieved purpose is to reduce the construction procedures in the process of assembling GRC boards and ensure the decorative effect of GRC boards.

[0011] To achieve the above technical objectives, the present utility model provides a pre-treatment structure for the splicing joints of GRC boards, including GRC boards, and the GRC boards include a decorative surface layer and a grid strip layer;

[0012] A pre-treatment grid strip is provided in the middle of the grid strip layer;

[0013] At least one pair of adjacent horizontal and vertical sides of the grid strip layer are respectively indented a certain distance towards the middle of the grid strip layer, so that after adjacent GRC boards are assembled, a post-indentation grid strip with the same size as the pre-treatment grid strip is formed between the adjacent grid strip layers.

[0014] Preferably, all the horizontal and vertical sides of the grid strip layer are respectively indented the same distance towards the middle of the grid strip layer.

[0015] Preferably, one pair of adjacent horizontal and vertical sides of the grid strip layer are respectively indented the same distance towards the middle of the grid strip layer, and the other pair of adjacent horizontal and vertical sides are respectively extended the same distance towards the outside of the grid strip layer;

[0016] After two adjacent GRC boards are assembled, a post-indentation grid strip with the same size as the pre-treatment grid strip is formed between the adjacent grid strip layers, where a horizontal or vertical side extended by one grid strip layer and a horizontal or vertical side indented by the other grid strip layer form the post-indentation grid strip.

[0017] Advantages of the present utility model:

[0018] Due to the above structural design of the present utility model, the same pre-treatment grid strip and post-indentation grid strip are directly formed after the GRC boards are assembled, and a better landscape effect is formed without secondary processing, reducing the uncertainty brought by secondary treatment; at the same time, the yellowing caused by using real stone paint is avoided, further ensuring the decorative effect.

[0025] The following will further illustrate the concept, specific structure and technical effects of the present utility model in conjunction with the drawings, so as to fully understand the purpose, features and effects of the present utility model.

[0026] Example:

[0027] As Figures 3 - 5 shown, the splicing joint pre-treatment structure of the GRC board includes a GRC board 1, and the GRC board 1 includes a decorative surface layer 5 and a dividing strip layer 6.

[0028] A pre-treated dividing strip 7 is provided in the middle of the dividing strip layer 6.

[0029] At least one pair of adjacent horizontal and vertical sides of the dividing strip layer 6 are respectively indented a certain distance towards the middle of the dividing strip layer 6, so that after adjacent GRC boards 1 are assembled, a post-recessed dividing strip 8 with the same size as the pre-treated dividing strip 7 is formed between the adjacent dividing strip layers 6.

[0030] The main innovation of the present utility model is that the pre-treated dividing strip 7 and the post-recessed dividing strip 8 of the same type are directly formed after the assembly of the GRC board 1, and a better landscape effect is formed without secondary processing, reducing the uncertainty brought by secondary treatment.

[0031] Specifically, in order to further ensure the decorative effect, the GRC board 1 can be pre-processed in the factory, and the pre-treated dividing strip 7 and the indented horizontal and vertical sides can be preset, so as to avoid the uncertainty caused by on-site secondary processing of the dividing strip layer 6 during construction.

[0032] The decorative surface layer 5 and the dividing strip layer 6 can be integrally formed without using real stone paint or other glue coatings, avoiding yellowing on the dividing strip layer 6 and affecting the decorative effect.

[0033] In this embodiment, one pair of adjacent horizontal and vertical sides c, d of the dividing strip layer 6 are respectively indented the same distance towards the middle of the dividing strip layer 6, and the other pair of adjacent horizontal and vertical sides a, b are respectively extended the same distance towards the outside of the dividing strip layer 6;

[0034] After two adjacent GRC boards 1 are assembled, a space is formed between the horizontal or vertical edges b, a extended by one grid strip layer 6 and the horizontal or vertical edges d, c retracted by the other grid strip layer 6. For example, the vertical edge a extended by one grid strip layer 6 is adjacent to the vertical edge retracted by the other grid strip layer 6, or the horizontal edge b extended by one grid strip layer 6 is adjacent to the horizontal edge d retracted by the other grid strip layer 6. In either case, a post-retracted grid strip 8 with the same size as the pre-treated grid strip 7 can be formed between the adjacent grid strip layers 6.

[0035] In some embodiments, all the horizontal and vertical edges of the grid strip layer 6 are retracted towards the middle of the grid strip layer 6 by the same distance.

[0036] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present invention without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present invention through logical analysis, reasoning, or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
