Description

Technical Field

[0001] The utility model relates to the technical field of extruded boards, in particular to a spliced ​​extruded board. Background Art

[0002] Extruded board is a hard board made of polystyrene resin as the main raw material, which is formed by high-mix extrusion and continuous extrusion foaming by special process. This product has a unique and perfect closed-cell honeycomb structure, and has the characteristics of high pressure resistance, moisture resistance, airtightness, non-absorption, corrosion resistance, low thermal conductivity, light weight, and long service life. It is widely used in the construction industry and is currently recognized as an extremely ideal thermal insulation material. However, there are still some problems when using existing spliced ​​extruded boards:

[0003] For example, a side-jointed extruded board with announcement number CN215253579U has a technical solution as follows: it includes a first splicing portion and a second splicing portion with the same width and thickness extending outward on both sides of the extruded board, and the first splicing portion is located below the second splicing portion in the height direction, the bottom surface of the first splicing portion and the top surface of the second splicing portion are flush with the bottom surface and the top surface of the board body respectively, a first limiting portion is provided on the top surface of the first splicing portion, and a second limiting portion is provided on the bottom surface of the second splicing portion. The side-jointed extruded board of the utility model can limit the two spliced ​​extruded boards by providing the first splicing portion and the second splicing portion, thereby avoiding the generation of gaps between the two extruded boards, thereby improving the thermal insulation effect. However, the existing extruded boards are only spliced ​​in an overlapping manner during the splicing process, and the splicing effect is not ideal. They will become loose when encountering external forces, and the splicing joints are not protected.

[0004] In view of this, we conducted in-depth research on the above issues, which led to the present case.
