Technical Field

The utility model relates to an external wall panel for a building, in particular to an external wall panel with an integrated heat preservation structure.

Background

Along with the continuous improvement of the energy-saving requirements of the buildings in China, the requirements on the heat insulation performance of the outer wall are also higher and higher. The sandwich external wall panel is a wall panel with better performance and wider application. For example, the sandwich external wall panel widely used in the prior art comprises an inner reinforced concrete layer, an outer reinforced concrete layer and a heat preservation layer in the middle, wherein a plurality of tie bars are arranged in the inner reinforced concrete layer, the outer reinforced concrete layer and the heat preservation layer in the middle.

Disclosure of Invention

The utility model aims to overcome the defects in the prior art and provide a novel external wall board-heat-insulation structure integrated external wall board, which has the advantages of simple structure, convenient manufacture, structural heat insulation integration realization, cost reduction and reliability improvement.

The technical scheme adopted for realizing the aim of the utility model is that the external wall panel with the integrated heat preservation structure comprises outer layer foam concrete, inner layer foam concrete and a heat preservation layer, and is structurally characterized in that n is more than or equal to 1 continuous trapezoid drawknot pieces distributed in a wave shape are adopted to penetrate through the external wall panel, the waists of the continuous trapezoid drawknot pieces penetrate through the heat preservation layer, and the adjacent trapezoid bottom edges (adjacent wave crests and wave troughs) of the continuous trapezoid drawknot pieces are respectively positioned in the outer layer foam concrete and the inner layer foam concrete.

The number of the continuous trapezoid drawknot pieces penetrating through the external wall panel is a natural number with n being more than or equal to 1, the specific number is determined according to the size of the external wall panel, and one continuous trapezoid drawknot piece can be arranged every 200-600 mm.

The continuous trapezoid drawknot piece penetrates through the outer wall plate in three modes (1) penetrates through the outer wall plate transversely; (2) longitudinally penetrates through the outer wall plate; (3) the two forms of transverse and longitudinal penetrate through the external wall panel at the same time. The continuous trapezoid drawknot member can penetrate through the outer wall plate in any one of the three modes.

According to the installation direction (transverse or longitudinal) of the external wall panel, the continuous trapezoid drawknot member can transversely penetrate through the external wall panel and also can longitudinally penetrate through the external wall panel so as to meet the drawknot requirement of the external protective layer. When the outer wall plate is transversely installed, the continuous trapezoid drawknot piece transversely penetrates through the outer wall plate, and when the outer wall plate is longitudinally installed, the continuous trapezoid drawknot piece longitudinally penetrates through the outer wall plate. In order to further increase the application range and firmness of the external wall panel, the continuous trapezoid drawknot piece can also penetrate through the external wall panel in a transverse and longitudinal mode at the same time, and the manufactured external wall panel can be suitable for any situation.

In order to further enhance the overall strength of the external wall panel, longitudinal stress ribs and transverse distribution ribs can be arranged in the inner foam concrete and are connected together and form a stress system together with the continuous trapezoid drawknot piece.

The outer layer foam concrete and the inner layer foam concrete are both high-strength foam concrete. The continuous trapezoid drawknot member adopts a nonmetal continuous trapezoid drawknot member such as fiber reinforced composite (FRP) and the like.

Reinforcing mesh or fiberglass mesh may be disposed within the outer foam concrete to strengthen the outer surface strength and prevent cracking.

The continuous trapezoid drawknot pieces distributed in a wave form penetrate through the outer wall plate, and penetrate through the heat insulation layer, so that reliable drawknot of the inner layer foam concrete and the outer layer foam concrete is realized, structural heat insulation integration is realized, the structure is simple, the manufacture is convenient, the anchoring force with the foam concrete is increased, the binding force between drawknot ribs and the foam concrete is increased, and the binding force between the inner layer foam concrete and the outer layer foam concrete is increased. The high-strength foam concrete is used as the outer layer foam concrete and the inner layer foam concrete, so that the functions of a stress structure and a protective shell are respectively realized, the stress is clear, and the structure is stable; the non-metal continuous trapezoid drawknot member such as FRP is adopted for inner and outer drawknot, so that the manufacture is simple and convenient, the cost is low, and the heat transfer of a cold bridge is eliminated (the heat transfer of the metal drawknot member can be increased by about 30%).
