Description

Technical Field

[0001] This utility model relates to the field of node insulation technology, and in particular to an insulation structure at the junction of the inner and outer surfaces of the basement roof of a building with a curtain wall. Background Technology

[0002] In building construction, thermal insulation structures are often installed to ensure overall energy conservation and efficient energy utilization. General insulation typically uses materials such as rock wool boards and polystyrene boards for a covering installation. At some critical points, such as the junction between the basement and the ground floor, targeted insulation is required. Generally, insulation is applied separately to the interior and exterior, but due to the discontinuity of the insulation layers, the insulation effect is poor. Furthermore, when the ground floor is a curtain wall structure, the joints need to ensure waterproofing, aesthetics, and insulation simultaneously, thus requiring more targeted design. Utility Model Content

[0003] This utility model provides a thermal insulation structure for the junction of the inner and outer surfaces of the basement roof of a building with a curtain wall, which solves the technical problems of thermal insulation, waterproofing and decoration at the junction of the inner and outer surfaces of the basement roof at the first-floor curtain wall.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A thermal insulation structure at the junction of the interior and exterior of the basement roof of a building with a curtain wall includes an exterior basement wall, a basement roof slab connected to the top of the exterior basement wall, a roof insulation board connected to the basement roof slab, a waterproof layer connected to the exterior of the exterior basement wall, a wall insulation board and a wall insulation layer sequentially arranged outside the waterproof layer, a curtain wall embedded part arranged at the top of the exterior basement wall, a curtain wall connecting part connected to the embedded part, a glass curtain wall arranged outside the curtain wall connecting part, a bottom decorative layer arranged below the glass curtain wall and outside the wall insulation layer, and an additional insulation layer arranged before the bottom decorative layer and the wall insulation layer and below the curtain wall connecting part.

[0006] Furthermore, the top of the basement exterior wall is higher than the basement roof slab, forming a stepped shape; the top insulation board has an upward-turned edge at the top of the basement exterior wall and is fully covered on the top of the basement exterior wall and extends out of the exterior wall, with the length of the extension adapting to the thickness of the wall waterproof layer and the thickness of the wall insulation board.

[0007] Furthermore, a sealing layer is provided between the section of the top insulation board extending out of the basement exterior wall and the top of the wall insulation board, and the thickness of the sealing layer is set according to the wall insulation board.

[0008] Furthermore, both the top insulation board and the wall insulation board are STP insulation boards with a thickness of not less than 30mm; the wall insulation board is installed with a length of not less than 1000mm from the elevation of 0m downwards.

[0009] Furthermore, the wall waterproofing layer is configured as two layers, one inside and one outside, and is laid along the entire length of the basement exterior wall; the top of the wall waterproofing layer is fixedly connected to the basement exterior wall by connecting nails; and the top of the wall waterproofing layer is sealed to the top surface of the insulation board.

[0010] Furthermore, the wall insulation layer is installed along the entire length of the basement exterior wall and has a thickness of not less than 50mm; the wall insulation layer is an extruded polystyrene foam board layer.

[0011] Furthermore, the top of the curtain wall embedded part is located below the bottom surface of the top insulation board; the curtain wall connecting part is a steel profile and is horizontally set, extending horizontally out of the wall insulation layer and detachably connected to the curtain wall keel.

[0013] The beneficial effects of this utility model are reflected in:

[0014] This invention, through the combined installation of a top insulation board and a wall insulation board, ensures the continuity of internal and external insulation at the junction, thereby improving insulation performance. Furthermore, the wall insulation board is only installed within a limited area at the junction, saving insulation materials and costs. The wall insulation layer installed on the outside of the wall insulation board ensures the overall insulation effect, playing a dual role in insulation. Combined with the additional insulation layer, it effectively ensures multiple layers of insulation at the junction. Secondly, the double installation of the wall waterproof layer and the connection between the top and top insulation boards ensure waterproofing and installation stability. The installation of the bottom decorative layer not only ensures the aesthetics of the bottom but also provides installation space for the additional insulation layer.
