DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 3 As shown, a building exterior insulation installation and fixing structure includes an original building insulation layer 1 fixed on the building exterior wall, a secondary insulation board 2 is installed on the outside of the original building insulation layer 1, the secondary insulation board 2 is connected to the building exterior wall through a fixed frame 4, a plaster hanging net 3 is provided on the outside of the secondary insulation board 2, the plaster hanging net 3 is fixed on the fixed frame 4, and a plaster layer is provided on the plaster hanging net 3.

[0023] The fixed frame includes a plurality of relatively fixed vertical fixed purlins 5 and transverse fixed purlins 6. The original building insulation layer 1 is provided with vertical fixing grooves 8 and transverse fixing grooves for accommodating the corresponding vertical fixed purlins 5 and transverse fixed purlins 6. The vertical fixed purlins 5 and transverse fixed purlins 6 each include a fixing base plate 9 and a reinforcing guide rail 10 mounted on the fixing base plate. The fixing base plate 9 of the vertical fixed purlins 5 is provided with fixing holes. The reinforcing guide rail 10 on the vertical fixed purlins 5 is provided with a connecting notch 11 at the fixing hole. The vertical fixed purlins 5 and transverse fixed purlins 6 are arranged perpendicular to each other. The transverse fixed purlin 6 is installed at the connecting notch 11 and fixedly connected to the fixing hole, thereby achieving relative fixation of the transverse fixed purlin 6 and the vertical fixed purlin 5.

[0024] The vertical purlins 5 are mounted on a height-adjustable base plate 9 at their base. A hexagonal connector is located at the top of the base plate 9, which receives a hexagonal socket. This allows the base plate 9 to adjust the position of the vertical purlins 5, facilitating the installation of secondary insulation panels of varying thicknesses. Once the base plate 9 is adjusted to the desired height, the vertical purlins 5 and the horizontal purlins 6 are secured to the building's exterior wall using expansion bolts.

[0025] A plurality of fixed connectors 7 are respectively installed on the vertical fixed purlins 5 and the horizontal fixed purlins 6. The fixed connectors 7 include a plurality of slides 13 installed on the reinforcing guide rails 10. The relative position of the slides 13 and the reinforcing guide rails 10 can be adjusted according to actual conditions to facilitate on-site installation. A vertical connecting plate 14 is fixedly installed on the upper end of each slide 13. Two limit baffles 15 are connected to the upper end of the vertical connecting plate 14. Preferably, the limit baffles 15 are hinged to the vertical connecting plate 14 by spring hinges. The secondary insulation board 2 is provided with mounting grooves 16. Under the elastic force of the spring hinges, the two limit baffles 15 respectively contact the bottom of the mounting grooves 16 on both sides of the vertical connecting plate 14 to achieve compression of the secondary insulation board 2. The limit baffles 15 can be freely flipped, which is convenient for on-site installation and improves installation efficiency. The gap between the limit baffles 15 and the mounting grooves 16 is filled with insulation strips 17 to improve the insulation effect and avoid the occurrence of cold and hot bridges. The joints of the new and old insulation boards can also be sealed by filling with insulation strips for a second gluing.

[0026] The plaster hanging net 3 is fixedly connected to the fixed base plate 9 through the insulation nails 18, and the insulation nails 18 pass through the limit baffle 15 to lock the limit baffle 15.

Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention, and various changes should be included in the scope of protection of the present invention.
