Dinging structure and dinging method for novel heat preservation and insulation building

Abstract

The invention discloses a dinging structure and a dinging method for a novel heat preservation and insulation building. The dinging structure is characterized in that the inside of the wall body (1) of a basic wall body is provided with a mortar levelling layer (2), a heat preservation and insulation layer (3), an anti-crack motor layer (4), an elastic water repellent facing layer (5) and a heat preservation and insulation decorative sheet layer (6), wherein the heat preservation and insulation layer (3) and the heat preservation and insulation decorative sheet layer (6) are made of the same material; and the heat preservation and insulation layer (3) can be made from foaming polystyrene / extruded polystyrene or made from polyurethane directly by foaming. The dinging method comprises the following steps: a, calking joints with a heat preservation and insulation material; b, extruding the anti-crack mortar into the joints; and c, treating the water repellent facing layer. The dinging structure and the dinging method have the advantages of increasing the crystal content of a mortar system, filling or blocking slit pores, reducing the porosity greatly, generating volume expansion, generating compression stress and compression strain in a body, compensating for various contraction distortions, and counteracting or partially counteracting corresponding pulling stress, thereby improving the overall cracking resistance and having the advantages of good heat insulation and preservation effect, strong anti-crack resistance and water resistance, good decorative performance, simple and convenient construction and the like.

Description

technical field [0001] The invention relates to a building structure, in particular to a jointing structure and method for a novel thermal insulation building, which is mainly used for jointing treatment of the external heat insulation structure of the external wall of the building enclosure structure. Background technique [0002] With the gradual implementation of my country's building energy-saving related standards, the development of some new thermal insulation building structures aimed at reducing energy consumption has begun to accelerate. In order to meet the actual needs of my country's construction projects, a number of new thermal insulation decorative panels have also come out one after another. At present, there are not many studies on pointing methods for this type of new thermal insulation building structure, and it is still in its infancy. The pointing methods currently applied to new thermal insulation decorative panels are mainly as follows: When the panel g...

Problems solved by technology

[0003] In the actual use of the original pointing technology of thermal insulation decorative panels, on the one hand, because the selected materials are all organic materials, the weather resistance is poor, and it is easy to affect the service life of the external thermal insulation system; on the other hand, due to the surface temperature of the material The change is drastic, the surface stress is large, and it is easy to form early temperature cracking. At the same time, the surface is not waterproof and hydrophobic during construction, which is easy to cause water infiltration, and then damage the external thermal insulation system structure, seriously affecting the thermal insulation effect
