A building exterior wall construction structure

technical field

The utility model relates to the field of construction engineering, in particular to a construction structure of an exterior wall of a building.

Background technique

The exterior wall of the building is the boundary wall that makes the whole building form indoors and outdoors, and the exterior wall of the building is used to enclose the building. The functions and functions of building exterior walls are as follows: bear a certain load, shelter from wind and rain, heat insulation, noise prevention, fire safety, etc. The construction structure of the existing building exterior wall is basically to scrape the mortar layer on the building exterior wall, and then paint the latex paint coating on the mortar layer. The beauty of the wall.

Contents of the invention

In view of the above, it is necessary for the utility model to provide a building exterior wall construction structure with good stability.

The technical scheme provided by the utility model is as follows: a building exterior wall construction structure, including a building wall, an interface agent layer is painted on the outer peripheral surface of the building wall, and a protective layer is provided on the outer peripheral surface of the interface agent layer. A coating layer is provided on the outer peripheral surface of the protective layer, the protective layer includes a glass fiber mesh cloth and a plastering mortar layer, the glass fiber mesh cloth is bonded on the interface agent layer, and the plastering mortar layer is coated with on the glass fiber mesh cloth and bonded to the interface agent layer.

Further, the paint layer is painted on the plastering mortar layer.

Further, the paint layer is an imitation sandstone paint.

Further, an alkali-resistant primer layer is provided on the outer peripheral surface of the protective layer, and the alkali-resistant primer layer is located between the plastering mortar layer and the paint layer.

Further, the flatness of the building wall is less than 1.5mm.

Compared with the prior art, the construction structure of the building exterior wall of the utility model has good stability, is not easy to fall off, shrink and crack, and the appearance of the construction structure of the exterior wall of the building is beautiful.

Description of drawings

Fig. 1 is the schematic diagram of the construction structure of the building exterior wall of the utility model.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. For example, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

Please refer to FIG. 1 , a building exterior wall construction structure includes a building wall 10 for enclosing a building, and the flatness of the building wall 10 is less than 1.5mm.

The outer peripheral surface of the building wall 10 is coated with an interface agent layer 20, the outer surface of the interface agent layer 20 is provided with a protective layer 30, and the outer peripheral surface of the protective layer 30 is coated with an alkali-resistant primer layer 40. The alkali-resistant A paint layer 50 is painted on the outer peripheral surface of the primer layer 40 . The interface agent 20 has super-strong adhesive force, excellent water resistance, and aging resistance, so as to improve the bonding strength of the protective layer 30 to the building wall 10, and can effectively avoid defects such as hollowing, falling off, shrinkage and cracking of the protective layer 30 The effect appears.

The protective layer 30 includes a glass fiber mesh cloth 31 and a plastering mortar layer 32, the glass fiber mesh cloth 31 is bonded on the interface agent layer 20; the plastering mortar layer 32 is coated on the glass fiber mesh cloth 31, and the The grid of the glass fiber mesh cloth 31 is bonded to the interface agent layer 20 to improve the stability of the plastering mortar layer 32 and prevent the plastering mortar layer 32 from cracking or coming off. thermal insulation.

The alkali-resistant primer layer 40 is painted on the plastering mortar layer 32, and the alkali-resistant primer layer 40 has strong water resistance and alkali resistance, so as to make the decorative effect lasting.

The paint layer 50 is painted on the outer peripheral surface of the alkali-resistant primer layer 40 to improve the aesthetics of the building wall 10. In this embodiment, the paint layer 50 is an imitation sandstone paint, which is not easy to fade and has a beautiful decorative effect.

The building exterior wall construction structure has short construction period, low cost, energy saving and environmental protection.

To sum up, the construction structure of the exterior wall of the utility model has good stability, is not easy to fall off, shrink, and crack, and the construction structure of the exterior wall of the building has a beautiful appearance.

The above is only an embodiment of the utility model, and does not limit the patent scope of the utility model. Any equivalent structure or equivalent process conversion made by using the content of the utility model description, or directly or indirectly used in other related technologies Fields are all included in the scope of patent protection of the utility model in the same way.
