Description

Technical Field

[0001] The utility model belongs to the technical field of heat preservation and thermal insulation of steel structure metal exterior walls, and in particular provides a metal exterior wall cold and hot bridge breaking structure, which is an anti-cold bridge structure realized by hinges between structural parts using a variety of common heat insulation materials. Background Art

[0002] At present, due to the large temperature difference between indoor and outdoor in winter and summer, condensation is very easy to occur in the metal exterior wall structure in the parts that cannot be completely insulated due to workmanship and other reasons, resulting in rust of metal components, causing great difficulties for the use and maintenance of the building, and it is very difficult to deal with after the building is put into use. Utility Model Content

[0003] The utility model aims to provide a metal exterior wall multi-break cold and hot bridge structure, which solves the problem of condensation on the metal exterior wall due to cold bridges and hot bridges, leading to rust on the metal components.

[0004] The utility model uses a "U-shaped clip" to hinge the main structure and the metal outer wall, plastic washers are arranged on the inside and outside of the bolts, nylon pads with low thermal conductivity are used at the hinges to break the bridge, and rock wool and glass wool are used on the outside of the "U-shaped clip" to break the bridge again, thereby realizing the structure of the metal outer wall breaking the cold and hot bridges.

[0005] The utility model comprises: a main structure 1, a metal U-shaped card 2, a bolt 3, a U-shaped card metal tail plate 4, a wall insulation 5, a nylon pad 6, a metal exterior wall plate 7, and insulation cotton 8; the U-shaped opening of the metal U-shaped card 2 is inserted into the main structure 1 of the metal exterior wall, and connected and fixed with bolts 3, two nylon pads 6 are used to separate the main structure 1 and the metal U-shaped card 2, and the outer side of the metal U-shaped card 2 is separated by wall insulation 5 and insulation cotton 8. The U-shaped card metal tail plate 4 is connected and fixed with the exterior wall modeling component by bolts 3, and plastic pads are arranged at the bolts, nuts and nuts.

[0006] The main structure 1 and the metal curtain wall keel are hinged with a metal U-shaped clip 2, and then fixed with mounting bolts. The mounting bolts are hinge bolts 3 with double plastic pads. Plastic washers are arranged inside and outside the hinge bolts to perform thermal insulation treatment on the metal bolts. The hinge between the metal U-shaped clip 2 and the main structure 1 is treated with a nylon pad 6 with a small thermal conductivity coefficient for thermal insulation treatment. The outside of the metal U-shaped clip 2 is treated with wall insulation 5 and thermal insulation cotton 8 for thermal insulation treatment again, thereby realizing the technology of thermally insulating the cold and hot bridges between the metal exterior wall panel 7 and the main structure 1.

[0007] The metal exterior wall keel is hinged to the main structure with a "metal U-shaped card". When installing, first align the nylon pad 6 with the hole position and fix it on the main structure 1. On both sides of the main steel structure column are nylon pads 6 of the same size as the metal U-shaped card 2, which prevents temperature conduction between the main structure 1 and the "metal U-shaped card", thereby achieving the first bridge breaking treatment.

[0008] The metal U-shaped card 2 is inserted into the corresponding position of the main structure 1 and the hole position is aligned. The first plastic gasket of the hinge bolt 3 with double plastic pads is passed through the hexagonal head side of the nut, and then the bolt is inserted into the three aligned holes of the metal U-shaped card 2, the main structure 1, and the nylon pad 6, and the second bolt plastic gasket is installed, and then the nut is installed and tightened. The hinge bolt 3 with double plastic pads is separated from the metal U-shaped card 2 by a plastic gasket. The isolation temperature is transmitted from the metal U-shaped card 2 to the hinge bolt 3 with double plastic pads, thereby realizing the second bridge breaking treatment.

[0009] Rock wool and glass wool are used to insulate the metal exterior wall keel from the inner and outer metal plates of the exterior wall. Thermal insulation wool and glass wool are used to block most of the temperature transmitted from the metal plate to the exterior wall keel, thus achieving the third insulated bridge treatment.

[0010] The utility model has the advantages that the components are reliably connected and the cold and heat bridges are completely cut off. BRIEF DESCRIPTION OF THE DRAWINGS
