Basement heat-insulating layer structure of passive low-energy-consumption building

Technical Field

The utility model relates to a thermal insulation wall structure, specific theory has related to a basement heat preservation structure of passive form low energy consumption building.

Background

With the development and progress of the building industry, the heat preservation requirement of the building is increased day by day, and the current active heat preservation measures comprise heating, air conditioning and the like, although the effect is obvious, the energy consumption is overlarge.

China and even the world face increasingly serious energy and environmental challenges, and the construction and popularization of low-energy-consumption buildings are not slow in the key period of accelerated transformation, innovation and crossing of the current building industry.

Based on this, passive low energy consumption building is in the process of transportation, and compared with the traditional building, the passive low energy consumption building has lower energy consumption and higher comfort level, is rapidly popularized and widely applied abroad at present, and forms some building design standards at home.

For example, in the national building standard design drawing set 16J908-8 passive low energy consumption building-residential building in severe cold and cold regions published by the institute of building standard design, there are two methods for producing the insulating layer of the bottom plate of the heating basement of the passive low energy consumption building:

1. as shown in fig. 1, the heat-insulating layer can be laid below the basement bottom plate and is continuous with the heat-insulating layer of the basement outer wall;

the disadvantages of this approach are: the heat-insulating layer is arranged below the basement bottom plate, bears the pressure of the whole building, has extremely high requirements on the material performance of the heat-insulating layer and is unfavorable for the seismic performance of the building.

2. As shown in fig. 2, the building block can be laid above the foundation slab and turned upwards by more than 1m along the inner side of the outer wall of the basement;

the disadvantages of this approach are: the heat preservation needs to turn up 1m at basement outer wall inboard, has influenced the use of interior space, and interior wall unevenness, very influences the fitment work in later stage.

In order to solve the above problems, people are always seeking an ideal technical solution.

Disclosure of Invention

The utility model aims at the not enough of prior art to a basement heat preservation layer structure of passive form low energy consumption building that design science, heat preservation continuity are good, require lowly, guaranteed interior space's integrality, improved structure shock resistance to the bearing capacity of heat preservation is provided.

In order to realize the purpose, the utility model discloses the technical scheme who adopts is: the utility model provides a basement heat preservation structure of passive form low energy consumption building, is including setting up in basement bottom plate lower extreme and with the crossbeam that the outer wall is parallel, and basement bottom plate below that rises to between the outer wall from the crossbeam sets up outer heat preservation, outer heat preservation is laid to the outer wall outside and is upturned to covering the outer wall in succession.

The basement structure is characterized by further comprising a plurality of longitudinal beams arranged below the basement bottom plate, wherein the longitudinal beams are perpendicular to and staggered with the cross beams, and the longitudinal beams are parallel to each other.

Basically, the distance between the beam and the outer wall is 1 m.

Basically, the longitudinal beam extends outwards to be flush with the outer wall.

And on the basis, an in-layer heat insulation layer is laid above the basement bottom plate, and the inner heat insulation layer extends outwards to the inner side of the outer wall.

Basically, the cross section of the beam is an inverted right trapezoid.

Compared with the prior art, the utility model has substantive characteristics and progress, in particular to the utility model, the crossbeam is designed at the lower end of the basement bottom plate, the outer end of the basement bottom plate is lifted, and the crossbeam bears most of the pressure of the basement bottom plate, so that the lower side of the outer end of the basement bottom plate is vacated with space for laying an outer heat preservation layer; due to the addition of the cross beam, the anti-seismic performance of the structure is better; meanwhile, the laying of the indoor heat-insulating layer does not need to be turned over, so that the continuous type of the heat-insulating layer can be ensured, and the integrity of the indoor space is guaranteed.

Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 3, a passive form low energy consumption building's basement heat preservation structure, including setting up in 1 lower extreme of basement bottom plate and with the crossbeam 3 that outer wall 2 is parallel, set up outer heat preservation 4 from crossbeam 3 to basement bottom plate 1 below between outer wall 2, the distance of crossbeam apart from between the outer wall is 1m, and the length of laying of heat preservation is also about 1 m. The external heat-insulating layer 4 is laid to the outer side of the external wall 2 and continuously turned upwards to cover the external wall 2.

An inner heat-insulating layer 6 is laid above the basement bottom plate 1, and the inner heat-insulating layer 6 extends outwards to the inner side of the outer wall 2.

Through increasing crossbeam 3, the basement bottom plate that the bearing was outwards chosen sets up the heat preservation in the below of the basement bottom plate of choosing, and the heat preservation is laid the outside to the outer wall always in succession, and under such structure, the pressure of basement bottom plate is shared by crossbeam 3, and outer heat preservation pressure-bearing is limited, just also no longer need possess high performance, and the cost is effectively controlled.
