Embodiment 1

[0028] Such as figure 1 A method for repairing an existing building wall insulation system is shown. The existing building wall insulation system includes a keel 2 and a metal exterior wall decorative panel 3 arranged outside the base wall 1. The repair method includes the following steps:

[0029] A. Keel 2 design: Use the finite element method to model the keel 2, calculate the building wind load, and design the material and density of the keel 2 according to the different heights and shape characteristics of the existing buildings;

[0030] B. Base treatment: Detect the flatness of the existing building walls, fix the drums and openings of the insulation layer on the base wall 1 with adhesives, so that the flatness of the base is less than 4mm;

[0031] C. Keel 2 laying: According to the design requirements, lay keel 2 on the outer surface of the existing building wall, and the keel 2 is anchored on the main structure of the building with anchor bolts;

[0032] D. Laying o...

Abstract

The invention relates to a repair method of an existing building wall thermal insulation system. The thermal insulation decoration system comprises a keel and metal outer wall decoration plates whichare arranged outside a base layer wall. The repair method comprises the steps of keel design, base layer treatment, keel laying, metal outer wall decoration plate laying and local cavity-free treatment. Through the combination of the metal outer wall decoration plate, an anchoring part and the keel, the thermal insulation system is integrally suspended on an existing wall, and procedures such as shoveling, layer-by-layer grouting are not needed, the construction steps are simple, the influence of existing thermal insulation system defects is avoided, and the applicability is high; according todifferent heights and body type characteristics of existing buildings, the keel material and density are designed, the fixing points of the metal outer wall decoration plates and the keel are increased, combined with the tongue-and-groove design of metal outer wall decoration plates and the local cavity-free treatment, the outward pulling force of negative wind pressure on the thermal insulationsystem can be born, and the load requirement is achieved; and the effect of ventilation and waterproofing is realized by combining the local cavity structure design, and the problems such as wall hollowing, cracking caused by water seepage are fundamentally solved.

Description

technical field [0001] The invention relates to the technical field of wall repair, in particular to a repair method for an existing building wall thermal insulation system. Background technique [0002] With the acceleration of my country's urbanization process, my country's construction industry has been vigorously developed, new buildings are increasing, and the application of external wall insulation is becoming more and more common. However, in the actual application process, due to the structural form of the building, climatic conditions, system materials, construction technology, construction management and other reasons, the wall is prone to hollowing, cracking, leakage, flooding and anti-frost, condensation, Falling off and other issues. In recent years, there have been frequent reports of large-scale cracks and shedding of exterior walls, which have resulted in loss of life and property. [0003] The conventional repair method on the market is to eradicate the or...
