Cement-based ultrahigh-performance artificial stone slab dry hanging and wet adhering structure

Abstract

The invention discloses a cement-based ultrahigh-performance artificial stone slab dry hanging and wet adhering structure which comprises an artificial stone slab and metal connectors. The artificialstone slab is made of ultrahigh-performance concrete, a stainless steel mesh is buried in the artificial stone slab, stainless steel nuts are fixedly welded on the stainless steel mesh, ports of the stainless steel nuts are flush with the back of the artificial stone slab, and intense vibration, intense compaction and vacuum pumping are carried out on the ultrahigh-performance concrete to obtain the artificial stone slab. The cement-based ultrahigh-performance artificial stone slab dry hanging and wet adhering structure has the advantages that the ultrahigh-performance concrete only has basicrequirements on necessary basic materials and formula processes, the stainless steel mesh capable of improving the detaching resistance is added to the cement-based ultrahigh-performance artificial stone slab dry hanging and wet adhering structure, main methods for manufacturing the slab include the intense vibration, the intense compaction and the vacuum pumping, accordingly, mountain excavatingand stone mining, high-temperature firing and chemical reaction can be omitted, discarded materials can be reused or can be used for manufacturing other building materials after the discarded materials are dehydrated and dried, and the cement-based ultrahigh-performance artificial stone slab dry hanging and wet adhering structure is completely free of pollution and emission; the shortcomings of environmental damage due to mountain excavating and stone mining for natural stone, energy wastage due to high-temperature pottery firing and environmental damage and pollution due to pottery clay mining can be overcome by the aid of the cement-based ultrahigh-performance artificial stone slab dry hanging and wet adhering structure.

Description

technical field [0001] The invention relates to the field of architectural decoration, in particular to a cement-based ultra-high-performance artificial stone slab dry-hanging and humidifying paste structure. Background technique [0002] Existing building exterior walls are decorated with stone-effect boards, mainly including natural stone boards and ceramic imitation stone boards. Natural stone boards are decorative boards made of naturally formed stones through cutting, grinding, sandblasting and other methods. The ceramic imitation stone board is a board with natural stone effect by firing clay at high temperature. There are two main installation methods: wet paste and dry hang. 1. Wet paste: Wet paste is to use sticky mortar to paste the board on the wall to be decorated. It is a rigid connection. Due to the thermal expansion and contraction caused by outdoor wind pressure, rain, and temperature difference, the viscosity of the mortar will be accelerated. In addition, ...

Problems solved by technology

1. Wet paste: Wet paste is to use sticky mortar to paste the board on the wall to be decorated. It is a rigid connection. Due to the thermal expansion and contraction caused by outdoor wind pressure, rain, and temperature difference, the viscosity of the mortar will be accelerated. In addition, the weight of the board is relatively large, so it is easy to cause the board to fall off, and the rigid connection is extremely poor in shock resistance. The current wet paste method is only used for decoration at the low-rise of the building, and the use of high-rise buildings is basically prohibited.

2. Dry hanging: The dry hanging of the board first needs to be installed on the wall to be decorated, and the metal dragon skeleton used to carry the board is installed. Since the naturally formed stone itself is in a solid state, the embedded parts for the external connection cannot be placed inside. Ceramics are also unable to place embedded parts because of high-temperature firing. When installing the two types of plates, only grooves or holes can be made on the side of the plates or holes can be drilled on the back of the plates, so that metal connectors can be used to connect and install the load-bearing frame. Stone and ceramics are relatively brittle. The connectors stuck in the side grooves or holes during installation need to bear the weight of the board. If the board is thin, the thin wall is easy to cause chipping and falling off; the back is punched, and the thinner board Punching holes are easy to break, and shallow holes are low in strength and poor in safety. Therefore, the thickness of dry-hanging stones is now stipulated to be no less than 25mm, and the time for ceramics to be dry-hanged is relatively short. To ensure its safety, the weight of the dry-hanging stone per square meter exceeds 65 kilograms, so that the dragon frame used to carry the plate also needs to maintain a certain strength to carry its weight, so the production and installation of the metal dragon frame is costly and heavy The cost of panel installation is also very high, and due to the heavy weight of the panel, the structure of the house needs to be enlarged to carry it, which also increases the cost of housing construction, stone mining damages the environment, and high-temperature firing of ceramics wastes energy and easily causes pollution

[0003] After searching, it was found that in order to solve the above problems, in the patent (patent number: 2014100884568) a kind of artificial slab stone production and its installation method, and in the patent (patent number: 201410694568X) a cement-based artificial slab that combines dry hanging and wet pasting In the stone installation method, the inventor made use of the characteristics of cement-based materials from liquid to solid, and pre-buried nuts and hooks that can be connected externally. After the board is solidified, the nut or hook is integrated with the board, which solves the problem of natural stone and ceramic boards. The gaps of the external connectors are pre-buried, and the plates are laid with mesh and fibers, so that the plates are not easy to break even when they are thinner, thus greatly reducing the weight of the plates and solving the problems caused by the heavy weight of natural stone and ceramic plates. Various gaps, waste stone chips of various colors and low-cost cement are used as the main materials for the board, and the advantages of concrete molding are used to overcome the gaps of stone mining and high-temperature firing of ceramics that damage the environment and waste energy. The above-mentioned gaps, but the board preparation is produced by a low-strength formula process, which has disadvantages such as low strength, low density, poor weather resistance, high water absorption, and poor freeze-thaw resistance. The strength is low, and the pre-embedded hook protrudes from the back of the board, which can easily affect the assembly line processing of the board, and the protruding hook is not easy to stack during transportation, and it is easy to cause the board to break
