Description

Building exterior wall insulation structure

technical field

The utility model relates to a thermal insulation structure for the outer wall of a building.

Background technique

my country is a big energy-consuming country, and the annual energy consumption is equivalent to 1.5 billion tons of standard coal, of which about 30% is the energy consumption of buildings. In order to reduce the energy consumption of buildings, insulation layers are arranged on the outer walls of existing buildings, and the buildings are wrapped with the insulation layers to reduce the energy consumption of buildings.

This kind of insulation layer is usually achieved by directly pasting the insulation board on the outer wall of the building to achieve the purpose of insulation. The insulation board is generally made of polystyrene, phenolic resin, glass wool, rock wool and other materials, and its existing problems Yes: 1. The insulation board is a prefabricated block structure with a certain hardness and weight. When installing, it is necessary to use an adhesive to stick the block insulation board to the outer wall. It is difficult to install, difficult to construct, and very dangerous 2. Since the insulation board is a whole structure, when it is installed on the wall, it is easy to cause the phenomenon of uneven outer surface; 3. Since the insulation board has a certain weight, this requires spraying on the outer surface of the insulation board. The sand should not be too thick to prevent it from falling off due to its heavy weight, but if the sandblasting is too thin, it will affect the protection of the insulation board and shorten its service life. The operation brings certain construction difficulties; 4. Since the insulation board needs to be assembled and butted to cover the wall, there must be a large number of seam thermal bridges, which will affect the insulation effect. 5. Since the prefabricated insulation boards are relatively flat, it is impossible to fit closely with the surface of the outer wall substrate. There are a large number of cavities between the insulation board and the wall that are conducive to air convection, which is not conducive to fire prevention and affects the insulation effect.

However, the invention may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

For ease of description, spatially relative terms such as "upper," "lower," "left," and "right" may be used herein to describe the relationship of one element or feature relative to another element or feature shown in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative specifications used herein interpreted accordingly.

As shown in Figures 1 to 5, the building exterior wall thermal insulation structure of the present utility model includes a building exterior wall 1, a keel 2, and a thermal insulation layer 4, and several keels 2 are installed on the building exterior wall 1 through anchor bolts 3.
