Coated rock wool board heat-preservation system for building curtain walls

Abstract

The invention belongs to the technical field of building heat preservation, and relates to a coated rock wool board heat-preservation system for building curtain walls. Coated rock wool boards are arranged between a leveling layer and the curtain walls, and connected with a base wall body in an anchorage manner by the penetration of anchor bolts through the leveling layer; board seams of the coated rock wool boards and the end parts of the anchor bolts are sealed in a pasting manner by aluminum foil to form a heat-insulation and heat-preservation external wall exterior heat-preservation layered structure; splicing parts of the block-shaped curtain walls are in sealing connection by clamps; the coated rock wool boards are in board-shaped structures; tongue-and-grooves for matched butting are formed at the two ends of each coated rock wool board; splicing parts of the tongue-and-grooves are fixed on the base wall body in an anchorage manner by fixing clamp boards; spacing seams are formed between the aluminum foil on the outer side faces of the coated rock wool boards and the curtain walls made of glass or stone boards; and an external wall of a building is sheathed with a heat-preservation structure mainly constructed by the coated rock wool boards, the aluminum foil, the curtain walls and the spacing seams to form the coated rock wool board heat-preservation system. The heat-preservation system is simple in structure, manpower-saving, low in cost, good in heat-preservation effect, simple and reasonable in construction technology, and environment-friendly.

Description

Technical field: [0001] The invention belongs to the technical field of building heat preservation, and relates to a film-coated rock wool board heat preservation system for an OLH building curtain wall used in a building group of an external wall heat preservation system of a curtain wall, in particular to a film-coated rock wool board heat preservation system for a building curtain wall. Background technique: [0002] Implementing energy conservation and emission reduction policies for buildings is a strategic task in my country. As a key indicator of green buildings, energy conservation and emission reduction, the thermal insulation performance of building exterior walls has been highly valued by the whole society. Traditional external wall insulation materials are mainly organic materials such as EPS, XPS and PU. Although organic materials have superior thermal insulation performance, their fire resistance is the Achilles heel. The burning problem of organic matter has no...

Problems solved by technology

Traditional external wall insulation materials are mainly organic materials such as EPS, XPS and PU. Although organic materials have superior thermal insulation performance, their fire resistance is the Achilles heel. The burning problem of organic matter has not been solved in construction applications. It is completely flame retardant under an open flame, and it will release a large amount of toxic gas when burning. Once a fire breaks out, it will definitely cause huge losses to people's lives and property.

In this context, the research, development and application of external wall insulation systems using inorganic materials (rock wool, glass wool, foam glass, etc.) It has a history of several decades, and has mature product standards and system certification guidelines (N13500-2003 and EN13162-2001); at present, the utilization rate of rock wool as building insulation materials in China is relatively low, and it started late, but it is in the national Under the mandatory policy adjustments issued, especially in recent years, the rock wool board external wall insulation system that is both thermal and fireproof has been developed and applied by leaps and bounds. The existing rock wool board external wall insulation system mainly includes rock wool board external wall insulation system. Cotton board composite slurry external wall thermal insulation system, rock wool board reinforced mesh (double layer mesh) thin plastered external wall thermal insulation system and rock wool board reinforced mesh (single layer mesh) thin plastered external wall thermal insulation system ; The external thermal insulation system of the rock wool board composite slurry exterior wall adopts an external hot-dip galvanized welded wire mesh, and a 20mm thick thermal insulation slurry is used as the protective layer of the rock wool board. The requirements are relatively low, and it is enough to meet the minimum value of the relevant standards, but the post-hot-dip galvanized welded mesh and thermal insulation slurry increase the load on the external wall, and there are many construction procedures, heavy labor workload, and high cost; rock wool board Reinforced mesh (double-layer mesh) thin plastered external wall external insulation system uses double-layer alkali-resistant mesh cloth and anti-cracking mortar on the outside of the rock wool board as a protective layer, which can not only protect the rock wool board, but also protect the rock wool board. The cost is reduced. This rock wool board external wall insulation system is also the most practical insulation system in China at present, but the quality requirements for the rock wool board material are high, and the tensile strength of the material cannot be less than 7.5kpa; rock wool board Reinforced mesh (single-layer mesh) thin plastered external wall external insulation system uses a single-layer alkali-resistant mesh cloth and anti-crack plaster mortar to place outside the rock wool board to reduce costs, but the requirements for rock wool board materials are very high. The tensile strength of the rock wool board material cannot be less than 15kpa, which is difficult and the material cost is very high

To sum up, the existing external wall thermal insulation systems of various rock wool boards are all based on the external thermal insulation system system developed directly on the rock wool board system as a decorative layer. The external wall decorative layer is generally paint, real stone paint, Texture paint or exterior wall bricks are directly used as a decorative layer on the rock wool board insulation system, which requires high requirements, complex structural systems, many construction procedures, heavy labor workload, and high costs.
