Description

Technical Field

[0001] The utility model relates to the field of building decoration energy saving, in particular to an aerogel-coated back-bolt type UHPC artificial stone plate. Background Art

[0002] Efficient thermal insulation is the foundation for achieving energy conservation and carbon reduction in buildings. Existing widely used organic and inorganic thermal insulation materials such as rock wool, extrusion, and calcium silicate generally have defects such as high thermal conductivity, fire resistance, and water resistance. With the increasingly high requirements for energy conservation and carbon reduction in buildings, the thickness requirements for these thermal insulation materials are also increasing. Several patents for cement-based artificial stone with back bolts have been disclosed. They all use back bolts in combination with screw hanging strips or anchors, and use the principle of clamping to clamp the various solid thermal insulation materials mentioned above, thereby achieving the decorative and thermal insulation functions of various buildings. The greater the thickness of the thermal insulation material, the farther the distance between the cement-based artificial stone board and the building structure will be, and the longer the suspension distance of the cement-based artificial stone board connected by bolts or screws will be. The longer the suspension distance, the greater the safety risks of the board. At the same time, boards and thermal insulation materials based on the clamping principle are also prone to problems such as delamination and panel popping.

[0003] Aerogel, hailed as one of the ten wonder materials, boasts extremely low thermal conductivity and excellent fire and water resistance. Therefore, aerogel can achieve highly effective thermal insulation with a very thin thickness. Due to its exceptional performance, aerogel is currently being actively promoted by the government. Currently, aerogel used for building insulation is primarily applied as a coating. The construction process involves first applying a primer to the wall, then applying an aerogel insulation coating over the primer. Finally, a decorative layer, such as stone lacquer or paint, is applied as needed. This coating process can only be applied on-site, resulting in low construction efficiency and difficulty in ensuring quality. The decorative layer is prone to fading, peeling, and water seepage. These defects can quickly lead to aerogel insulation and decorative systems becoming dilapidated and outdated, shortening the lifespan of the aerogel, and even causing serious safety issues such as shedding. Furthermore, the finish coating, primarily composed of chemical materials, violates the concept of green building materials, and the predominantly manual on-site application violates the development requirements of prefabricated buildings. Therefore, how to make aerogels more efficient, durable, green and energy-saving in buildings is a difficult problem that needs to be solved urgently. Utility Model Content

[0004] The purpose of the present invention is to provide an aerogel-coated back-bolt UHPC artificial stone board to solve the problems raised in the above background technology.

[0005] The technical solution adopted by the utility model is: an aerogel-coated back-bolted UHPC artificial stone plate, comprising a back-bolted UHPC artificial stone plate, a plurality of nuts are pre-embedded on the back of the UHPC artificial stone plate, the back of the back-bolted UHPC artificial stone plate is coated with an aerogel layer, and the aerogel layer is provided with through holes leading to the screw holes of the nuts.

[0006] Preferably, a primer layer is provided between the back-bolted UHPC artificial stone board and the aerogel layer.

[0007] Preferably, the surface of the aerogel layer is coated with a protective layer.

[0008] Preferably, a hanging screw is passed through the through hole, the front end of the hanging screw passes through the through hole and is threadedly connected to the nut, and the tail end of the hanging screw is connected to the metal connecting piece.

[0009] Preferably, a metal connector is provided on the hanging screw, and the metal connector is one or a combination of an L-shaped metal connecting piece and a straight metal connecting piece.

[0010] Preferably, an anchoring connecting rod is passed through the through hole, and the anchoring connecting rod passes through the through hole and is threadedly connected to the nut. An anchoring portion is provided on the main body of the anchoring connecting rod, and the anchoring portion protrudes from the surface of the aerogel layer.

[0011] Preferably, a mesh is embedded in the back-bolt type UHPC artificial stone plate, and the nut is connected to the mesh.

[0012] This utility model utilizes high-performance UHPC artificial stone panels as decorative panels. By industrially coating the back of the panels with aerogel, a highly effective aerogel insulation layer is formed. The aerogel's extremely low thermal conductivity ensures effective insulation even in extremely thin layers. Furthermore, the primer layer ensures a tighter adhesion of the aerogel insulation layer to the back of the panels. Once the thin, high-performance aerogel is applied to the back of the UHPC artificial stone panels, various screw-on connectors on the back allow the panels to be securely fastened to various building structures. This effectively addresses the safety risks associated with existing cement-based artificial stone panels combined with existing insulation materials with high thermal conductivity, such as large thickness and long hanging distances, as well as the tendency for delamination and rebounding. The aerogel's excellent fire resistance enhances the panels' fire resistance. Its excellent water resistance also effectively prevents the panels from being corroded by various contaminants, further enhancing the safety characteristics of the artificial stone panels.

[0013] The surface of the UHPC artificial stone panels of this utility model can be formed into various decorative effects such as stone and metal through peeling, wrapping, and printing. The high-performance UHPC artificial stone panels, formed through the peeling principle, can fully achieve the service life of natural stone. Using UHPC panels as the base material to wrap metal panels can be more cost-effective than metal veneers and honeycomb panels, and has better safety and durability. This effectively solves the various defects that are inherent in the stone paint, coatings, and thin-shell coatings used when applying aerogel to building walls, such as easy fading, peeling, and water seepage. At the same time, the UHPC artificial stone panels with back bolts can achieve various fully assembled installations through the principle of screw interconnection, thus simultaneously solving the various defects of aerogel insulation decoration on existing buildings, which can only be implemented manually on-site.

[0014] The UHPC artificial stone panels of this utility model fully meet the requirements of three-star green building materials, thus resolving the green challenges of coatings and stone paints. After being coated with aerogel on the backside, these high-performance UHPC artificial stone panels, as a finishing surface, effectively block the erosion and damage of the aerogel coating by harmful substances such as ultraviolet rays, rain, and snow. This effectively extends the service life of the aerogel and further blocks the erosion and damage of these harmful substances on the building structure, thereby also increasing the service life of the main structure. These advantages are unattainable with existing aerogel coating processes. Therefore, this utility model is an innovative technology that benefits both the country and the people.
