Embodiment 1

[0033] The structure of the same life, self-insulating external wall and beams and columns, including the wall filled with frame structure. The wall consists of 4 layers from the outside to the inside, followed by the outer insulation layer 101, the outer bearing layer 102, the center layer 103 and The inner bearing layer 104; the outer bearing layer 102, the center layer 103 and the inner bearing layer 104 are located on the upper part of the frame beam 105; the interface between the outer insulation layer 101 and the outer bearing layer 102 and the frame beam 105 and frame column 108 The outer surface of the outer thermal insulation layer 101 protrudes to the outside of the frame beam 105, and its outer surface is flush with the outer surface of the frame beam 105 and the additional thermal insulation board 107 on the frame column 108.

[0034] The wall is masonry made of autoclaved aerated concrete blocks. The blocks used in the same wall have external insulation layer 101, ext...

Embodiment 2

[0039] In severe cold areas, energy saving on external walls requires higher thermal resistance. The thickness of the outer thermal insulation layer 101, the outer bearing layer 102, the central layer 103 and the inner bearing layer 104 are 80mm, 60mm, 190mm and 30mm respectively. Example 1 is the same.

Embodiment 3

[0041] In earthquake-prone areas, for buildings with earthquake-resistant magnitude 8 and crack degree 9, the thickness of the outer insulation layer 101, the outer bearing layer 102, the central layer 103 and the inner bearing layer 104 are 50mm, 60mm, 140mm, 50mm, respectively; The density of the outer bearing layer 102 and the inner bearing layer 104 is 950KG / M 3 , The amount of cement in the pouring mix is ​​increased by 5%, and the other settings are the same as in Example 1.

[0042] The construction method of the structure of the same life, self-insulating external wall and beams and columns includes the following steps:

[0043] 1. Set the outer insulation layer 101, the outer bearing layer 102, the center layer 103 and the outer wall of the outer wall block according to the nature, size and engineering construction specifications of the outer wall, the arrangement of the outer wall masonry blocks, and the deviation of the construction process. The thickness, strength and d...

Abstract

The invention relates to an equal-lifetime self-insulation exterior wall and beam column structure, and a construction method thereof and belongs to the technical field of building energy conservation. The equal-lifetime self-insulation exterior wall and beam column structure comprising a frame-embedded wall is characterized in that the wall comprises an outer insulation layer (101), an outer bearing layer (102), a central layer (103) and an inner bearing layer (104) sequentially from outside to inside; the outer bearing layer (102), the central layer (103) and the inner bearing layer (104) are located on the upper portion of a frame beam (105); an interface between the outer insulation layer (101) and the outer bearing layer (102) is level to the outer surface of the frame beam (105) and the outer surface of a frame column (105); the outer insulation layer (101) projects out of the frame beam (105), and the outer surface of the outer insulation layer (101) is level to the outer surface of an insulation plate (107) added to the frame beam (105) and the frame column (108). The equal-lifetime self-insulation exterior wall and beam column structure has the advantages that the exterior wall is large in heat resistance, the target of saving energy by 65% is satisfied, the wall is large in bending resistance, the stress structure is reasonable, and the equal-lifetime self-insulation exterior wall and beam column structure is convenient to construct and equal in lifetime.

Description

Technical field [0001] The structure and construction method of the same-life, self-insulating outer wall and beam and column belong to the technical field of building energy saving, and specifically relates to a structure and construction method of an outer wall and beam and column. Background technique [0002] In the field of energy-saving building technology, autoclaved aerated concrete blocks are widely used in the outer wall of the house envelope. The blocks that reach the 4MPa outer wall compressive strength index have low thermal insulation performance and meet the national building energy saving target of 65%. , The gap is obvious. Organic foam insulation is often added. Compared with cement-based components and building materials with a long service life, these organic materials have a shorter service life and constitute potential defects in the service life of housing construction. [0003] A house with a wall self-insulation system refers to a wall system formed of aut...
