Patent Description:
Existing building walls are decorated with stone-effect panels, mainly including natural stone panels and ceramic imitation slates. Natural stone panels are decorative panels made of naturally formed stone by cutting, grinding, sandblasting and other methods. Ceramic imitation slate is made by firing clay into a natural stone effect plate at high temperature. The installation methods mainly include wet pasting and dry hanging. Wet sticking: Wet sticking is the use of sticky mortar to stick the plate on the wall to be decorated. It is a rigid connection. Due to outdoor wind pressure, rain, and thermal expansion and contraction caused by temperature differences, it will accelerate the viscosity of the mortar Reduced, coupled with the large weight of the plate, it is easy to cause the plate to fall off, and the rigid connection is extremely poor in seismic resistance. The current wet paste method is only used for decoration in the low-rise building, and the use of the high-rise building is basically prohibited. Dry hanging: firstly, you need to install the metal dragon frame to support the plate on the wall to be decorated. Since the naturally formed stone is already in a solid state, the embedded parts for external hanging connection cannot be placed inside. Ceramics cannot be placed inside due to high temperature firing. The two plates can only be slotted or perforated on the side of the plate or perforated on the back of the plate during installation, and then metal connectors can be used to connect and install the load-bearing dragon skeleton. Stones and ceramics are inherently brittle, and the connectors that are stuck in the side grooves or holes during installation need to bear the weight of the plate. If the plate is thin, the thin wall will easily cause the edge to fall off; the back is punched, and the thin plate Perforation is easy to break, and the strength of shallow hole hanging is low and safety is poor. Therefore, the thickness of dry hanging stone cannot be less than <NUM>. The time for ceramics to be used for dry hanging is relatively short. There is no standard for its thickness, but the ceramic plate needs a certain thickness. To ensure its safety, the weight of the dry hanging stone is more than <NUM> per square meter, so that the dragon skeleton used for the load-bearing plate also needs to maintain a certain strength to carry its weight. This causes the production and installation of the metal dragon skeleton to be expensive and heavier. Plate installation costs are also high, and due to the heavy weight of the plate, the house structure needs to be enlarged to carry it. This also increases the cost of house construction, stone mining damages the environment, and ceramic high-temperature firing wastes energy and can easily cause pollution.

After searching, it was found that in order to solve the above problems, in the patent (Patent No.: <CIT>) a method of making and installing artificial plate stone, and the patent (Patent No.: <CIT>) using a combination of dry hanging and wet paste cement-based artificial plate. In the stone installation method, the inventor used the characteristics of cement-based materials from liquid to solid, and embedded nuts and hooks that can be connected externally. After the plate is solidified, the nuts or hooks are integrated with the plate, which solves the problem of natural stone and ceramic plates. The defects of the plug-in connectors are embedded, and the plates are laid with mesh and fibers, so that the plates are not easy to break even when they are thin, which greatly reduces the weight of the plates and solves the problems caused by the heavy weight of natural stone and ceramic plates. This kind of shortcomings, the plate uses discarded stone chips of various colors and low-cost cement as the main materials, and uses the advantages of concrete molding to overcome the shortcomings of stone mining and high-temperature firing of ceramics that destroy the environment and waste energy. Although the above shortcomings are effectively solved, However, the plate design is produced by low-strength technology, which has the disadvantages of low strength, low density, poor weather resistance, high water absorption, and poor freeze-thaw resistance. Since the embedded nuts are placed independently, the hanging strength is low. The buried hook protrudes on the back of the plate, which easily affects the assembly line processing of the plate, and the protruding hook is not easy to stack during transportation, which may easily cause the plate to break. Documents <CIT> and <CIT> are also relevant documents in the art.

The object of the present invention is to provide a cement-based ultra-high-performance artificial stone plate to solve the above-mentioned problems in the background art.

To achieve the above objectives, the present invention provides a cement-based ultra-high-performance artificial stone according to claim <NUM>.

Preferably, thickness of the cement-based plate body is <NUM>-<NUM>.

Preferably, the mesh is a stainless steel mesh, and the nut is a stainless steel nut.

Preferably, screw opening of the nut is not lower than back of the cement-based plate body of <NUM>.

Preferably, the screw opening of the nut is level with back of the cement-based plate body.

Preferably, the bottom of the nut is provided with a wing plate around the nut.

Preferably, nut body of the nut passes through hole of the mesh, and the wing plate of the nut is located at bottom of the hole of the mesh, and size of the wing plate is larger than size of the hole of the mesh.

Preferably, bottom the nuts is welded and fixed on the stainless steel mesh.

Preferably, number of the nut is two or more.

The present invention uses the basic materials and formula technology necessary for ultra-high performance concrete (UHPC) as the basic requirements, and takes strong vibration, strong pressure, and vacuum as the main plate making methods. Strong pressure and vacuum are difficult to achieve in the production of ultra-high-performance concrete in existing bridges and bridges; strong pressure combined with water-absorbing cloth can squeeze out and absorb water from the plate; vacuum can extract the gas and excess water in the plate Both, the two can reduce the moisture by more than <NUM>%, and can make the density of the plate higher, so as to achieve the principle condition that the ultra-high performance concrete water-binder ratio is lower and the strength is higher.

The meshes connected by the whole plate are used as aggregate, which has a better connection and support skeleton than the dispersive steel fibers necessary for ultra-high performance concrete. The protrusions formed by extrusion are multiple A pressed body, such as a carved plate or a molded plate, is formed by strong pressure on the back of the plate, so that the mesh does not float out of the surface of the plate, and the protrusions are extruded as part of the ultra-high-performance concrete, allowing the mesh to solidify Afterwards, it is completely integrated with the plate body, and multiple protrusions form a uniform pressing on each point in the mesh, so that the mesh is stabilized in the ultra-high performance concrete plate and integrated with it. The nut used for the external connection is connected with the mesh together, and has a very high pull strength. The nut flush with the back of the plate is convenient for assembly line processing and transportation. In this way, when the nut is mounted, the stress points are connected to the entire plate, which has a very high mounting strength, which overcomes the defects of the original cement-based artificial stone independently placed nuts and low mounting strength when independently stressed.

Thickness of the plate of the present invention is about <NUM>, so that weight of the plate is greatly reduced. The plate made by the invention has the remarkable characteristics of ultra-high strength, high toughness and high durability possessed by ultra-high performance concrete, which is more than several times better than the performance indicators of ordinary strength concrete, so as to completely overcome the original cement-based plate strength of the inventor Low, low density, poor disassembly resistance, poor weather resistance, poor freeze-thaw resistance and other defects.

The present invention makes full use of the screwing advantages of the nut and screw, and can be connected with any shaped metal connector, which can complete dry hanging humidification stickers, dry hanging with or without skeleton, and any plate cutting combination with metal connecting bars. The shape of the line can be used to clamp the thermal insulation plate of any material to form an integrated thermal insulation plate with an extended screw through a nut and a metal strip, and can be installed quickly and safely.

The invention does not require quarrying in the mountains, no high-temperature firing, no chemical reaction, and the waste materials can be reused or other building materials after dehydration and drying, completely achieving zero pollution and zero emissions. It overcomes the disadvantages of natural stone quarrying and damaging the environment, high-temperature firing of ceramics wastes energy, and the destruction of the environment caused by the mining of pottery clay is a technology that benefits the country and the people. Therefore, there is room for improvement within the art.
