Cement-based ultrahigh performance artificial stone slab ceiling structure

Abstract

The invention discloses a cement-based ultrahigh performance artificial stone slab ceiling structure. The cement-based ultrahigh performance artificial stone slab ceiling structure comprises an artificial stone slab, bearing metal keels and transverse keels, a ceiling further comprises L-shaped metal connectors and n-shaped metal clamps, a stainless steel mesh is embedded in the artificial stone slab, nuts are arranged in the stainless steel mesh, and end openings of the nuts are flush with the back of the artificial stone slab. According to the cement-based ultrahigh performance artificial stone slab ceiling structure, the pre-embedded stainless steel mesh fused with the slab into a whole has extremely high hanging-mounting strength, the hanging point of each nut is in force-bearing connection with the whole slab completely, through fracture resistance of the stainless steel mesh and tight connectivity between the stainless steel mesh and aggregate, even though only one point is adopted for fixing, the breaking falling-off phenomenon is avoided, and thus the potential safety hazard of falling-off caused by the large weight, large brittleness, low hanging strength and large fallingimpact force of natural stone slab and a ceramic stone-imitated slab is avoided.

Description

technical field [0001] The invention belongs to the field of architectural decoration, in particular to a cement-based ultra-high-performance artificial stone plate suspended ceiling structure. Background technique [0002] For the beautification of existing buildings, after people complete the decoration and beautification of indoor and outdoor walls and floors, the indoor roof and outdoor corridors and eaves play an overall role in the whole decoration and beautification process. It makes people feel perfect, so the ceiling is becoming more and more important in architectural decoration. A good ceiling should be rich in color to coordinate with the decoration style of the house. The position of the ceiling is high and it is not easy to scrub and replace. Fading, anti-aging, moisture-proof, anti-corrosion, durable, easy-to-clean materials, but also need to have: anti-static, sound insulation, heat insulation, fire prevention and other basic functions. There are mainly main...

AI Technical Summary

Problems solved by technology

All the above materials have certain disadvantages: 1. Gypsum (composite) board: poor moisture resistance, not easy to scrub, single color, easy to change color

2. PVC board: poor high temperature resistance, easy deformation, easy aging, poor environmental protection

3. Metal plate: poor thermal insulation, high installation requirements, large seam gap

4. Wooden board: easily affected by temperature and humidity, easy to deform, twist, warp, crack, poor fire resistance

Due to the high brittleness of natural stone and ceramics, the side of the thinner plate is slotted or punched, and the metal connector stuck in the groove or hole is easy to cause chipping and falling off due to the weight of the plate; thinner Punching holes on the back of the board is easy to cause the board to break, and the hanging strength of the shallow hole is low, and the safety is poor. Therefore, the thickness of the dry-hanging stone on the external wall should not be less than 25mm, and the time for the ceramic board (brick) to be dry-hanged is short. The thickness standard is mandatory, but in order to ensure safety, a certain thickness is also required. The weight of the dry-hanging stone per square meter exceeds 65 kg

The dry hanging of natural stone and ceramic imitation stone slabs (bricks) on the wall belongs to the vertical force, and the force generated by the metal connector is mainly used to fix the slab. Even if a certain point cracks or falls off, other stress points can also Temporarily guarantee its safety; the suspended ceiling makes the board completely suspended on the top, and its board is completely in the overall downward gravity environment. If a certain point falls off, the falling impact of the board can easily cause greater impact on other hanging points , In addition, the board itself is brittle and has poor bending resistance, and the hanging point is easily broken, causing the whole board to fall off. The suspended ceiling belongs to the place where people's activities are frequent, and the top falls off easily causing major safety accidents. Based on the above reasons, natural stone boards and Ceramic imitation stone slabs (bricks) have not been widely used in suspended ceilings
