Description

Technical Field

[0001] This invention relates to the field of ultra-low energy buildings, and more particularly to an installation structure for exterior doors and windows of ultra-low energy buildings with ALC panel systems. Background Technology

[0002] Compared to traditional buildings, ultra-low energy buildings place significantly higher demands on the thermal performance and airtightness of their external envelope. This is especially true in ALC (Alternating Current Concrete) composite wall systems, where the connection between the ALC panels and exterior windows must be reliable, while also ensuring thermal bridge-free joints and overall airtightness. Simultaneously, ease of installation must be considered. For example, in conventional steel structure systems, exterior doors and windows are often installed using angle steel welding or through-bolt fixing, with metal connectors directly connecting the interior and exterior, easily creating linear thermal bridges. Actual measurement data shows that the thermal bridge loss coefficient for such structures can reach 0.08–0.12 W / (m·K), resulting in an overall heat transfer coefficient exceeding the standard by more than 30%. Furthermore, the significant thermal differences between the ALC panels and various connectors further exacerbate the risk of localized condensation, and the airtightness between the three components cannot be guaranteed.

[0003] For example, existing patent CN220365172U discloses an ALC panel window construction structure, including a reserved opening, a horizontal ALC panel set at the top of the reserved opening, vertical ALC panels on the sides and bottom, and flat steel fixedly installed on the inner wall of the opening. Adjacent flat steels are welded end-to-end. Each end of the horizontal ALC panel has a connecting clip; one side of the connecting clip engages and is fixed to the end of the horizontal ALC panel, and the other side engages and is fixed to the vertical ALC panel. The connecting clip includes a connecting plate and fixing plates fixed on opposite sides of the connecting plate. Two fixing plates are provided on each side of the connecting plate, forming a slot between the two connecting plates for engaging the horizontal or vertical ALC panel. This application replaces cast-in-place reinforced concrete lintels with flat steel and horizontal ALC panels, and replaces cast-in-place reinforced concrete structural columns with vertical ALC panels. The ALC panel door and window opening construction structure provided by this utility model strengthens the opening structure with components such as flat steel to meet the installation requirements of external doors and windows. However, this solution does not consider thermal bridging and the overall airtightness of the building, and only meets the installation requirements of external windows. Summary of the Invention

[0004] To ensure that the installation of exterior doors and windows in ALC panel systems meets the requirements of ultra-low energy consumption buildings, and to ensure that there are no thermal bridges at the connection nodes and that the structural airtightness requirements are met, this invention provides an installation structure for exterior doors and windows suitable for ultra-low energy consumption buildings using ALC panel systems. Through a reasonable structural design, the requirements for no thermal bridges and airtightness in the installation of exterior doors and windows in ALC panel systems are met, while optimizing the construction process and reducing the risk of overlapping operations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An installation structure for exterior doors and windows in ultra-low energy consumption buildings using an ALC (Alternating Current Carrier) panel system includes ALC panels, flat steel, external insulation, hook bolts, channel steel, angle steel, thermal insulation blocks, thermal insulation pads, exterior window frames, infill insulation, waterproof and breathable membrane, waterproof and vapor-tight membrane, pre-compressed expansion sealing strip, and metal window sills. The exterior window frames are fixed to the thermal insulation blocks.

[0007] Furthermore, thermal insulation pads separate the outer window frame from the channel steel;

[0008] Furthermore, thermal insulation is applied between the outer window frame and the ALC strip;

[0009] Furthermore, the heat insulation pad is fixed inside the channel steel;

[0010] Furthermore, hook bolts are used to secure the ALC strips;

[0011] Furthermore, the angle steel is connected to the hook bolt;

[0012] Furthermore, the waterproof vapor barrier membrane is adhered to the indoor side;

[0013] Furthermore, one end of the waterproof vapor barrier membrane is pasted onto the outer window frame, and the other end is covered with angle steel and hook bolts and pasted onto the ALC strip;

[0014] Furthermore, the waterproof and breathable membrane is adhered to the outdoor side;

[0015] Furthermore, one end of the waterproof and breathable membrane is attached to the outer window frame, while the other end is covered with insulation and attached to the ALC strip with hook bolts.

[0016] Furthermore, the external insulation is laid in a double-layer staggered pattern on the ALC strips;

[0017] Furthermore, the external insulation is covered with an upward-filling insulation layer;

[0018] Furthermore, the metal window sill is fixed to the bottom of the outer window frame;

[0019] Furthermore, a pre-compressed expansion sealing strip is filled between the metal window sill and the external insulation.

[0020] Furthermore, the external insulation should cover the external window frame as much as possible.

[0021] The beneficial effects achieved by this invention, compared with conventional practices, are that by optimizing the structure, it not only ensures that the installation of the ALC panel system for exterior walls, doors and windows meets safety requirements, but also meets the requirements of ultra-low energy consumption buildings for no thermal bridges and airtightness. It also optimizes the construction process, avoids cross-operations of multiple trades, and improves the reliability and thermal performance of each system. Attached Figure Description

Detailed Implementation

[0025] The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The technical problem to be solved by this invention is to overcome the shortcomings of existing solutions, such as... Figure 1 , Figure 2 As shown, the present invention provides an installation structure for exterior doors and windows of ultra-low energy consumption buildings with ALC strip panel system, including ALC strip panels, flat steel, external insulation, hook bolts, channel steel, angle steel, heat insulation pads, heat insulation gaskets, exterior window frames, filling insulation, waterproof and breathable membrane, waterproof and vapor barrier membrane, pre-compressed expansion sealing strip, and metal window sill.

[0027] The channel steel is connected to the building structure via flat steel, ensuring the structural reliability of the exterior window installation and solving the problem that ALC panels cannot be used as load-bearing components due to their low density.

[0028] The thermal insulation pad is fixed inside the channel steel, and the outer window frame is fixed on the thermal insulation pad. This utilizes the structural strength of the channel steel and avoids direct contact between the outer window frame and the channel steel, thus preventing thermal bridges. Furthermore, the thermal insulation pad separates the outer window frame from the channel steel, preventing contact thermal bridges caused by construction errors or material errors.

[0029] The aforementioned insulation filling is placed between the outer window frame and the ALC strip. In actual engineering, this insulation filling can be replaced by ALC strip, wooden strip, or other thermal insulation materials with a thermal conductivity not greater than that of the ALC strip, to fill the gap between the outer window and the ALC strip wall.

[0030] The hook bolts are used to fix the ALC strips; the angle steel connected to the hook bolts is a fixing method for the ALC strip installation, which is not related to the installation of the exterior window itself. However, since the hook bolts pass through the ALC strips, the connection point needs to be airtight.

[0031] The waterproof and vapor barrier membrane is pasted on the indoor side, with one end pasted on the outer window frame and the other end covered by angle steel and hook bolts pasted on the ALC strip.

[0032] The waterproof and breathable membrane is attached to the outdoor side, with one end attached to the outer window frame and the other end covered with insulation and attached to the ALC strip with hook bolts.

[0033] The external insulation is laid on the ALC strip with double staggered joints; the external insulation covers and fills the insulation layer upwards, and the insulation layer should be pasted with double staggered joints, and the construction should be carried out by a combination of adhesive and anchoring according to the calculation requirements.

[0034] The metal window sill is fixed below the outer window frame to facilitate drainage of the outer window and provide effective protection for the external insulation; a pre-compressed expansion sealing strip is filled between the metal window sill and the external insulation.

[0035] The external insulation should cover the external window frame as much as possible to minimize thermal bridging during window installation.

[0036] The above specific embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
