DETAILED DESCRIPTION

[0016] The utility model is further described below with reference to the accompanying drawings.

[0017] like Figure 1-Figure 3 As shown, one side of the insulation board 2 is a base plate 2-1, and the other side is a glass fiber layer 2-2. The metal keel 1 is fixedly connected to the wall 4. The insulation board 2 is installed between the metal keels 1 on both sides, and the glass fiber layer 2-2 is installed toward the wall 4. One end of the pressing plate 3 is rotatably connected to the outer side of the metal keel 1, and the other end of the pressing plate 3 is pressed on the outer side of the insulation board 2. The middle of the pressing plate 3 is fixed to the metal keel 1 by screws.

[0018] The wall 4 is provided with a mounting hole 4 - 1 , in which an expansion tube 5 is placed. Outward flanges 1 - 1 are provided on both sides of the metal keel 1 , and self-tapping screws 6 are screwed into the expansion tube 5 through the countersunk holes at the flanges 1 - 1 .

[0019] Grooves 2-3 are provided on both sides of the glass fiber layer 2-2 of the insulation board 2, and the flanges 1-1 are embedded in the grooves 2-3.

[0020] The metal keel 1 is filled with thermal insulation material.

[0021] A heat-insulating pad 7 is provided at the connection point of the self-tapping screws 6 between the metal keel 1 and the wall 4 .

[0022] Two sides of the base plate 2-1 of the heat preservation plate 2 are provided with grooves 2-4, and the pressing plate 3 is embedded in the grooves 2-4 when pressed tightly.

[0023] The outer side of the metal keel 1 is provided with decorative panel mounting holes 1 - 2 .

[0024] When the utility model is used, firstly, a mounting hole 4-1 is made on the wall 4, and then an expansion tube 5 is placed in the mounting hole 4-1, and a self-tapping screw 6 is screwed into the expansion tube 5 through the countersunk hole. The expansion tube 5 expands under the pressure of the self-tapping screw 6, and generates a strong friction force with the mounting hole 4-1, so that the metal keel 1 is fixed to the wall 4. The metal keel 1 can be installed horizontally or vertically. After multiple metal keels 1 are installed in parallel, an insulation board 2 is installed between the metal keels 1. The glass fiber layer 2-2 of the insulation board 2 is installed toward the wall 4 to isolate the temperature of the wall 4. The pressing plate 3 presses both sides of the base plate 2-1, presses the glass fiber layer 2-2 on the wall 4, and prevents the glass fiber layer 2-2 from being separated from the base plate 2-1. One end of the pressing plate 3 can be rotatably connected to the metal keel 1 through a pin shaft. After the pressing plate 3 rotates and presses the insulation board 2, it only needs to be fixed and locked with screws to facilitate workers to quickly install.

[0025] The metal keel 1 can be filled with insulation materials such as polyurethane, and an insulation pad 7 made of a material with a low thermal conductivity such as plastic or cork can be installed at the connection between the self-tapping screws 6 between the metal keel 1 and the wall 4. This can reduce the heat transfer between the wall 4 and the metal keel 1, prevent the metal keel 1 from forming a cold bridge, and further improve the insulation effect.

[0026] Grooves 1-3 and 2-4 can be cut on both sides of the base plate 2-1 and the glass fiber layer 2-2 of the insulation board 2, respectively. The flange 1-1 is embedded in the groove 2-4, and the pressure plate 3 is embedded in the groove 1-3, so that the installation structure is more fitting and compact. The pressure plate 3 can be embedded outside the metal keel 1, so that the pressure plate 3 is flush with the surface of the metal keel 1 after the insulation board 2 is installed, making the overall structure more compact. The metal keel 1 is provided with a structure of multiple groups of pressure plates 3, and the insulation board 2 is arranged and installed between the metal keels 1 in sequence to complete the installation of the internal insulation of the exterior wall. The decorative panel can be installed on the outside of the metal keel 1 through the decorative panel installation hole 1-2 to cover the overall structure.
