A construction method of aac thermal insulation laminated wall panel structure for exterior wall of frame structure

Abstract

The invention discloses a construction method for an AAC thermal insulation laminated wall panel structure of a frame structure exterior wall, comprising the steps of: 1. pouring a water retaining platform; 3. Review of the actual height of the AAC thermal insulation laminated wall panels; 4. Fix the upper limit fixture of the laminated exterior wall panel and the lower limit fixture of the laminated exterior wall panel; 5. Install the AAC thermal insulation laminated exterior wall panel; 6. Fix The upper limit fixture of the laminated inner wall panel and the lower limit fixture of the laminated inner wall panel; 7. Install the AAC thermal insulation laminated inner wall panel. The invention is simple in construction, adding and optimizing structural measures such as anchoring nodes, water-stop and reverse sill at the root of the wall, which not only ensures the earthquake resistance, thermal bridge insulation, heat preservation and durability of the laminated thermal insulation wallboard related structures, but also meets the needs of safe construction, improved Requirements such as work efficiency and reduced labor intensity fill in the deficiencies in existing industry technical regulations and standard atlas-related construction practices, and are energy-saving and effective.

Problems solved by technology

[0002] AAC (Autoclaved lightweight sand Aerated Concrete) insulation composite wallboard is an autoclaved lightweight sand aerated concrete insulation composite wallboard, which has the advantages of light weight, good fire resistance and sound insulation performance, green environmental protection, economy, and convenient construction. It is widely used in exterior wall panels, interior wall panels, floor panels and roof panels. Atlas 06CGC01 of "Autoclaved Lightweight Sand Air-entrained Concrete (AAC) Block and Plate Structure Structure" currently used in architectural design, "Autoclaved Lightweight Aerated sand aerated concrete (AAC) blocks and slab building structures" Atlas 06CJC05, "Technical Specifications for Lightweight Autoclaved Aerated Concrete Blocks and Slabs" DBJ61 / T89-2014, from the aspects of building earthquake resistance, waterproof, heat preservation and energy saving and The above-mentioned standards have the following deficiencies: first, the structural nodes used for fixing and anti-seismic anchoring in the atlas are only applicable to the structure of single-layer thermal insulation wall panels, and lack the methods of fixing and anti-seismic anchoring of laminated wall panels; The size of the clamps, U-shaped clamps and hook-head clamps in the original atlas are only suitable for the seismic anchorage of non-superimposed thermal insulation wall panels, and at the same time, the superimposed installation of the entire board is compatible with the original U-shaped clamps and hook-head clamps. The installation process is not matched, and it belongs to the side of the building, so it is difficult to guarantee safety. It is also necessary to improve the joint form of the superimposed structure and the fixture structure, and meet the relevant requirements of construction and installation; The joints connected by the hook bolt method or the sliding bolt method, their clip joints and bolt joints all pass through the inside and outside of the laminated wall panel, the installation joints of doors and windows are complicated, and there are thermal bridges, which cannot eliminate the thermal bridge phenomenon and cannot meet the energy saving requirements; Third, AAC panels are not suitable for long-term immersion in water, otherwise they are prone to creep deformation, and the interlayer roots related to building exterior walls, the surroundings of doors and windows, etc. are prone to water seepage, and their durability is poor; fourth, the existing Relevant construction methods are only suitable for single-layer self-insulating exterior wall panels, not suitable for thermal insulation laminated wall panels, and the construction methods and techniques need to be improved
