Description

Wall structure

Technical Field

The utility model relates to a building technical field especially relates to a wall structure.

Background

The implementation of relevant requirements such as building energy-saving standards and building fire prevention specifications promotes the rapid development of wall heat-insulating materials. In order to fully utilize the heat insulation effect of an organic heat insulation material and meet GB50016-2014 fire protection specifications, the existing cast-in-place heat insulation external formwork is widely used for coating a 5cm non-combustible fire protection layer on the outer side of a B-level fire insulation material in a scraping mode, almost all polystyrene particle adhesive cement or vitrified micro-bead adhesive cement with 2-3cm is used as a transition layer at present, and a 3-2cm mortar protection layer is additionally arranged to meet the requirement of the 5cm non-combustible fire protection layer. The transition layer mainly plays a role in increasing the mechanical strength of the outer template and reducing the cracking degree of the screeding leveling layer.

However, when the polystyrene particle adhesive cement or the vitrified microsphere adhesive cement is used as a transition layer, the formed structure has strong air permeability and water permeability, the heat preservation effect is poor, the heat conductivity coefficient is generally between 0.07 and 0.10W/(m.K), and the integral thickness and the unit area weight of the outer template are greatly increased; if the polystyrene particle cement mortar is used as the heat insulation layer, the whole thickness of the outer template is greatly increased, and the unit area weight of the outer template is also greatly increased due to the cement components contained in the polystyrene particle cement mortar, so that the polystyrene particle cement mortar is not suitable for being used as the heat insulation layer independently. Along with the continuous improvement of the heat preservation and energy conservation standard, the whole thickness of the outer template is thicker and heavier, so that the construction is more and more limited, and the potential safety hazard is seriously increased.

Chinese patent application No. 201520727791.8 provides a fire prevention type cast-in-place concrete composite heat preservation template, which is composed of protective layers at two outer sides and a middle inorganic material wrapped polyphenyl particle/organic heat preservation material composite board, and has the effects of good heat preservation and heat insulation performance and high strength. However, the inorganic material is mainly used in the inorganic material-coated organic particle layer (about 90%), and the inorganic-coated organic particle layer mainly made of inorganic material and the organic heat-insulating material layer belong to two material layers with very different properties, so that the inorganic material-coated organic particle layer and the organic heat-insulating material layer have different shrinkability. In this regard, the thickness of the inorganic material-wrapped organic particle layer and the protective layer is often increased, so that the same problems as the above-mentioned "the whole thickness of the outer form is increased and the weight is increased, which leads to more and more limited construction and serious increase of potential safety hazard" can occur.

Therefore, the existing wall is generally thicker after meeting the national standard, the room rate is low, and because the insulation board used in the wall is heavier, the construction is difficult, and safety accidents are easy to happen when workers move and lift the wall. This is a disadvantage of the prior art.
