[0042] Among them, the upper end of the insulation panel 111 can be provided with an insert block 114 or a slot 115, which is set according to actual needs and is not specifically restricted here. The setting direction of the insert block 114 of the insulation panel 111 needs to be kept consistent to reduce construction difficulty and improve construction efficiency.

[0043] See also Figure 2 and Figure 3 , Figure 2 A cross-sectional view of an energy-saving building exterior wall according to the present invention is shown. Figure 3 The invention provides an energy-saving building exterior wall, wherein a groove 116 is vertically arranged in the middle of the inner wall of the insulation plate 111, and the groove 116 is detachably plugged with the connector 13.

[0044] Among them, the positions of the grooves 116 and the connecting pieces 13 correspond, and the grooves 116 of the upper and lower adjacent insulation panels 111 are on the same straight line and can be connected to form a long through groove. The spacing between the left and right adjacent long through grooves is the setting spacing between each group of connecting pieces 13.

[0045] The present invention provides an energy-saving building exterior wall, wherein the connecting member 13 comprises a clamping block 131 , which is longitudinally arranged on the outside of the facade of the exterior wall base layer 10 , and the clamping block 131 is matched with the connecting member 13 .

[0046] The block 131 may be configured in a dovetail shape to strengthen the connection between the thermal insulation layer 11 and the exterior wall base layer 10 .

[0047] The pad 132 is disposed between the block 131 and the exterior wall base 10 , and the pad 132 is attached to the exterior surface of the exterior wall base 10 .

[0058] The filling body 14 may be bonding mortar. Pouring bonding mortar into the gap between the exterior wall base layer 10 and the insulation layer 11 can achieve a stable connection and further enhance the insulation effect of the exterior wall.

[0059] See also Figure 5 , showing a schematic flow chart of a construction method of a building energy-saving exterior wall of the present invention. The present invention provides a construction method of a building energy-saving exterior wall, comprising the following steps:

[0060] Execute step S210: clean the concrete structure wall to be constructed to obtain the outer wall base layer 10.

[0061] The purpose of cleaning the concrete structural wall is to facilitate the subsequent structural installation of the wall facade and ensure the stability of the connection. Then, step S220 is executed.

[0062] Execute step S220: install a plurality of connectors 13 at intervals on the outer surface of the outer wall base layer 10 .

[0063] Among them, the installation position of the connecting member 13 should be set according to the spacing of the grooves 116 on the insulation board 111. The installation of the connecting member 13 is to first anchor the pad 132 to the outer surface of the outer wall base 10 with anchor nails 133, and then connect the block 131 to the outside of the pad 132, and set the block 131 vertically to correspond to the groove 116, and then execute step S230.

[0064] Execute step S230: stack the insulation panels 111 from bottom to top on the outer surface of the outer wall base layer 10 to form the insulation layer 11, and connect the insulation panels 111 and the connectors 13 accordingly.

[0065] Among them, the stacking process of the insulation panels 111 is to connect the upper and lower adjacent insulation panels 111 through the relatively arranged plug blocks 114 and slots 115, and the left and right adjacent insulation panels 111 are slidably connected through the relatively arranged connecting grooves 112 and connecting blocks 113, which can ensure the stability of the connection. The assembly method can adapt to multiple sizes of exterior wall bases 10 and has wide applicability. Then, execute step S240.

[0066] Execute step S240: pour the filling body 14 into the gap between the exterior wall base layer 10 and the thermal insulation layer 11 .

[0067] The filler 14 fills the gap, so that a reliable connection is formed between the exterior wall base layer 10 and the insulation layer 11 , and then step S250 is performed.

[0068] Execute step S250: apply a protective layer 12 on the outer wall of the thermal insulation layer 11 .

[0069] Among them, applying the protective layer 12 includes applying a first mortar layer 121 on the outer wall of the insulation layer 11, then hanging a fiberglass mesh 122 on the first mortar layer 121, and finally applying a second mortar layer 123 on the outer side of the fiberglass mesh 122. This coating method enhances weather resistance and anti-aging capabilities, and can effectively prevent the insulation layer 11 from being eroded and damaged by the external environment, thereby extending the service life of the exterior wall.
