[0022] Embodiment 2: This embodiment is a further description of the external window lintel structure described in Embodiment 1. In this embodiment, when the lintel insulation layer 3 uses non-hydrophobic insulation material, in order to avoid heat preservation The layer is damp, reducing the performance of the thermal insulation material. There is a gap between the outer beam 1 and the lintel insulation layer 3. The gap is used as a moisture-proof air layer, and the distance between the outer beam 1 and the lintel insulation layer 3 is equal to the wall air space The thickness of the layer.

[0023] Specific embodiment three: this embodiment is a further description of the external window lintel structure described in specific embodiment 1. In this embodiment, a roof insulation layer 10 is laid between the outer wall 7 and the roof, and the roof insulation The thickness of layer 10 is 50 mm. Laying a roof insulation layer 10 between the outer wall 7 and the roof can cut off the thermal bridge of this part, further achieving the purpose of insulation.

Abstract

The invention relates to the technical field of window body insulation structure construction, and provides an exterior window lintel structure. The exterior window lintel structure is to solve the thermal bridge problem caused by an excessive heat transfer coefficient of an exterior window lintel. The exterior window lintel structure includes an outer beam, a lintel insulating layer and an innerbeam which are arranged in sequence from outside to inside; the thickness of the outer beam is the same as the thickness of an outer wall, and the thickness of the inner beam is the same as the thickness of an inner wall. The bottom of the lintel insulating layer is provided with a steel wire mesh; the outer surface of the steel wire mesh is coated with mortar. The outer beam and the inner beam are connected by two parallel reinforcing steel bars in a pulling mode, and the reinforcing steel bars are horizontally arranged. The exterior window lintel structure is fixed between the top portion ofan exterior window frame and a wall body. The exterior window lintel structure is suitable for the construction of demonstration houses in villages and towns in severe cold regions, and is particularly suitable for exterior window lintels of intermittently heating houses in villages and towns in severe cold regions.

Description

Technical field [0001] The invention belongs to the technical field of window insulation structure construction. Background technique [0002] Village houses in severe cold areas usually have independent heating systems. For intermittently heated village houses using kang as heating method, light-weight and high-efficiency insulation materials with a small heat storage coefficient should be installed inside the outer wall structure to reduce the attenuation of the enclosure structure. Degree, the load-bearing wall is arranged on the side close to the outdoor. [0003] Taking into account the production and living habits of villages and towns, farm tools are often stacked indoors or ornaments are placed on the inner surface of the wall, so a protective wall is added inside the insulation layer to form a sandwich insulation structure. However, since the insulation material is arranged on the inner side, it cannot cover the entire wall structure. In addition, the external window lin...
