Embodiment 1

[0033] The construction of self-insulating exterior walls and beams and columns with the same life span, including walls filled with frame structures, consists of 4 layers from the outside to the inside, which are the outer heat insulation layer 101, the outer load-bearing layer 102, the central layer 103 and the The inner load-bearing layer 104; the outer load-bearing layer 102, the central layer 103 and the inner load-bearing layer 104 are located on the upper part of the frame beam 105; The outer surface of the outer heat insulation layer 101 protrudes to the outside of the frame beam 105, and its outer surface is flush with the outer surface of the additional insulation board 107 on the frame beam 105 and the frame column 108.

[0034] The wall is built with blocks made of autoclaved aerated concrete, and the blocks used in the same wall include an outer heat insulation layer 101, an outer load-bearing layer 102, and a central layer 103 corresponding to the required size an...

Embodiment 2

[0039]In severe cold regions, higher thermal resistance is required for exterior wall energy saving. The thicknesses of the outer heat insulation layer 101, outer load-bearing layer 102, central layer 103, and inner load-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 seismic fortification level 8 and crack degree 9, the thickness of the outer heat insulation layer 101, outer load-bearing layer 102, central layer 103 and inner load-bearing layer 104 is 50mm, 60mm, 140mm, and 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 ratio is increased by 5%, and the rest of the settings are the same as in Example 1.

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

[0043] 1. Set the outer heat insulation layer 101, outer bearing layer 102, center layer 103 and The thickness, strength and density of the inner bearing layer 104, the shape and size elements of the pre-set tie reinforcement on the design block;

[0044] 2. According to the above strength requirements, determine the density an...

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 external wall and beam column belong to the technical field of building energy conservation, and specifically relate to a structure and construction method of an external wall and beam column. Background technique [0002] In the field of energy-saving building technology, autoclaved aerated concrete blocks are widely used in the outer walls of building enclosure structures. Blocks with a compressive strength index of 4MPa outer walls have low thermal insulation performance and meet the national goal of 65% energy saving in building buildings. , the difference is obvious. Organic foam insulation layer measures are often added. Compared with cement-based components and building materials with a long lifespan, these organic materials have a shorter service life, which constitutes a potential defect for the service life of the building. [0003] The house with wall self-insulation sy...
