Preferably, one side of the lightweight core layer is provided with a tenon, and the other side opposite to the tenon is provided with a tenon groove opposite to the tenon.

Preferably, the shape of the tenon matches the shape of the groove.

Preferably, the shape of the tenon is dovetail or trapezoidal or rectangular or arcuate.

Preferably, the tenon is located on the upper side of the lightweight core layer, and the tongue groove is located on the lower side of the lightweight core layer.

Preferably, the connecting piece is arranged obliquely downward relative to the panel layer.

Preferably, the connecting piece is fixedly connected to the steel mesh.

Preferably, the connection between the connecting piece and the steel mesh is welded.

Preferably, a sealing layer is provided on the outer wall of the lower end portion of the panel layer, and the lower edge of the sealing layer exceeds the lower edge of the panel layer.

Preferably, the sealing layer is made of flexible material.

Owing to adopting the present application of above-mentioned technical scheme to have following advantage:

1. The building energy-saving exterior wall of this application includes a panel layer, a lightweight core layer and a cement mortar layer arranged sequentially from outside to inside. Since the cement mortar layer is always provided with a steel mesh as a skeleton, and the panel layer, The lightweight core layer and the cement mortar layer are connected into a reliable whole, so that the building energy-saving exterior wall of the application has good earthquake resistance;

2. Since there is a lightweight core layer made of foamed concrete between the panel layer and the cement mortar layer, first of all, the weight of the outer wall is reduced, which is convenient for installation and fixing, and also has good thermal insulation performance ;

3. Since the panel is made of calcium silicate board, it has good moisture-proof and anti-leakage performance, so the moisture-proof and anti-leakage ability of the energy-saving exterior wall of the building of this application is further improved.

detailed description

In order to make the purpose, technical solutions and advantages of the embodiments of the utility model more clear, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the utility model. Obviously, the described The embodiments are part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the present invention. The scope of utility model protection.

Embodiment 1, as shown in Figure 1:

An energy-saving exterior wall of a building, comprising a panel layer 1, a lightweight core layer 2 and a cement mortar layer 3 arranged sequentially from outside to inside, the panel layer 1 is a calcium silicate board, and the lightweight core layer 2 is: A concrete slab formed by pouring foam concrete, the cement mortar layer 3 is: a cement mortar slab with a steel mesh 4 inside as a skeleton, and the energy-saving exterior wall also includes several connecting pieces 5 arranged separately. The connecting piece 5 runs through the panel layer 1, the lightweight core layer 2 and the cement mortar layer 3 in turn, and the two ends of the connecting piece 5 are also provided with a pressing piece 6, and one side of the lightweight core layer 2 is provided There is a tenon 7, and the other side opposite to the tenon 7 is provided with a tenon groove 8 opposite to the tenon 7, the shape of the tenon 7 matches the shape of the tenon groove 8, and the tenon 7 The shape is dovetail or trapezoidal or rectangular or arc-shaped, the tenon 7 is located on the upper side of the lightweight core layer 2, the tenon groove 8 is located on the lower side of the lightweight core layer 2, and the connection The member 5 is arranged obliquely downward relative to the panel layer 1, the connecting member 5 is fixedly connected to the steel mesh 4, the connecting member 5 and the steel mesh 4 are welded, and the panel A sealing layer 9 is arranged on the outer wall of the lower end part of the layer 1, the lower edge of the sealing layer 9 exceeds the lower edge of the panel layer 1, and the sealing layer 9 is made of flexible material.

The building energy-saving exterior wall of this embodiment includes a panel layer 1, a lightweight core layer 2 and a cement mortar layer 3 arranged sequentially from outside to inside. Since the cement mortar layer 3 is always provided with a steel mesh 4 as a skeleton, and connectors are used 5. Connect the panel layer 1, the lightweight core layer 2 and the cement mortar layer 3 into a reliable whole, so that the building energy-saving exterior wall of this embodiment has good earthquake resistance; The lightweight core layer 2 made of foamed concrete is provided, first of all, the weight of the outer wall is reduced, it is convenient to install and fix, and it also has good thermal insulation performance; since the panel is made of calcium silicate board, it has Good moisture-proof and anti-leakage performance, so the moisture-proof and anti-leakage ability of the building energy-saving exterior wall of this embodiment is further improved; the welding between the connector 5 and the steel mesh 4 further improves the structure of the exterior wall of this embodiment stability and reliability; and, due to the setting of the mortise 8 and the tenon 7, in the actual use process, multiple exterior wall structures can be assembled to obtain a larger area of the exterior wall structure, further expanding the scope of application; Since the tenon 7 is arranged on the upper side and the tenon groove 8 is arranged on the lower side, after assembly, rainwater is not easy to flow into the tenon groove 8, which further ensures the anti-leakage ability of the outer wall of this embodiment; The panel layer 1 is arranged obliquely downward, which also makes it difficult for rainwater to flow into the gap between the connecting piece 5 and the panel layer 1; at the same time, due to the setting of the sealing layer 9, after a plurality of outer wall structures are assembled, it can pass through the sealing layer 9 The gap between the adjacent outer walls of the sealing plate, thus further ensuring the imitation leakage ability of the outer walls of this embodiment.
