Description

Technical Field

[0001] The invention relates to the technical field of ancient building restoration, in particular to a thermal insulation composite board for ancient building restoration. Background Art

[0002] Due to their unique historical and cultural value, ancient buildings need to pay special attention to protecting their original appearance and structural safety during the restoration process. At the same time, ancient buildings often have problems such as high energy consumption and poor thermal insulation performance, so effective thermal insulation measures need to be taken. The application of thermal insulation technology can effectively solve the energy consumption problem of buildings and improve the comfort and service life of buildings. As an important carrier of culture and history, the restoration and protection of ancient buildings is particularly important. As a new type of building material, thermal insulation composite panels are gradually being used in the restoration of ancient buildings due to their excellent thermal insulation performance and construction convenience. A composite plate structure with heat insulation effect and a preparation method thereof are disclosed in the announcement number CN114033055A. A heat insulation board is prepared by adopting a preparation method of a composite plate structure with heat insulation effect. The preparation method includes the following steps: preparing materials, making heat insulation materials, making heat insulation materials, making heat insulation mechanisms, making heat insulation mechanisms, combined splicing and cement pressing. The upper heat insulation substrate, the lower heat insulation substrate and the middle heat insulation substrate are layered and spliced ​​together. The upper heat insulation substrate, the lower heat insulation substrate and the middle heat insulation substrate all have excellent heat insulation performance; the upper heat insulation substrate and the lower heat insulation substrate have excellent heat insulation performance, and the three groups of heat insulation substrates and the two groups of heat insulation substrates work simultaneously to improve the heat insulation performance of the device; the arrangement of the card slot and the card block increases the bonding area between the upper heat insulation substrate and the lower heat insulation substrate, and improves the stability of the splicing between the upper heat insulation substrate and the lower heat insulation substrate; At present, when using thermal insulation composite panels, special tapes or other adhesives are mainly used for splicing. There may be gaps or unevenness between the panels, which not only affects the aesthetics, but also may reduce the thermal insulation effect. When the above-mentioned prior art is used, the thermal insulation composite panels are connected by gluing, which is cumbersome to operate and inconvenient to assemble freely. The fixed size and shape of the composite panels limit their adaptability in different usage conditions and environments. Due to the inconvenience of free assembly, more time and manpower may be required for adjustment and alignment during the installation process, which reduces construction efficiency and increases installation costs. In projects such as ancient building restoration, this additional cost and time consumption are particularly significant, so corresponding improvements are needed; A building waterproof, thermal insulation composite board is disclosed in the announcement number CN110158854A, including a square fixing frame, a decorative panel is fixed and sealed with an adhesive on the front of the square fixing frame, and a mounting board is fixed and sealed with an adhesive on the back of the square fixing frame, and a first waterproof board, a thermal insulation board and a second waterproof board are sequentially arranged inside the square fixing frame from front to back. The present invention also discloses a method for producing a building waterproof, thermal insulation composite board, including four steps. The present invention proposes a building waterproof, thermal insulation composite board, which is not only simple in structure, but also has good waterproof, thermal insulation and heat insulation performance. It adopts a modular design and can be prefabricated in advance, which can effectively shorten the construction period and improve the construction efficiency. At the same time, it makes its construction less difficult, more convenient to construct and has a wider range of applications. The proposed method for producing a building waterproof, thermal insulation composite board has simple process steps, is scientific and reasonable, and is easy to implement; When the above-mentioned prior art is used, when assembling the composite panels, the composite panels are mainly assembled by the cooperation of the blocks and the slots. The connection strength is insufficient, and the connection method of the blocks and slots may become loose or displaced when subjected to force. Especially when subjected to external forces such as wind pressure and snow pressure for a long time, the connection parts may fail due to fatigue, which in turn affects the firmness of the splicing of the composite panels and increases the subsequent maintenance costs. Therefore, corresponding improvements are needed. Summary of the invention
