Description

Technical Field

[0001] The utility model relates to the technical field of building curtain walls, in particular to an ultra-low energy consumption building curtain wall. Background Art

[0002] The architectural curtain wall is a structural system of the building's exterior facade, usually made of glass, metal, concrete or other materials. It is located on the outside of the building and not only provides an aesthetically pleasing exterior surface, but also has functions such as thermal insulation, heat insulation, and sound insulation. The architectural curtain wall uses different forms and materials to achieve diverse design styles and functional requirements. As an important part of modern architecture, the architectural curtain wall not only provides a beautiful appearance, but also improves the building's energy efficiency and improves the quality of the indoor environment. It is an indispensable part of architectural design.

[0003] However, the existing metal frame non-transparent composite insulation curtain wall has the problems of many structural layers and high material cost. The "Passive Ultra-Low Energy Consumption Civil Building Energy Saving Technical Standard" requires higher insulation performance standards for the enclosure structure. In extremely cold and cold areas, the insulation layer made of traditional insulation materials needs to be more than 200mm thick to meet the exterior wall heat transfer coefficient standard. Walls with too thick insulation layers will occupy usable space, are easy to fall off and have high costs. Utility Model Content

[0004] The purpose of the utility model is to provide an ultra-low energy consumption building curtain wall which is easy to construct, safe, durable and low in cost, so as to solve the technical problems in the above-mentioned background technology that the overly thick insulation layer wall occupies the usable space, is easy to fall off and has a high cost.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an ultra-low energy consumption building curtain wall, comprising a curtain wall panel and a concrete substrate, wherein the curtain wall panel is provided with a concrete substrate, a rectangular groove is opened on the concrete substrate, an insulation board is embedded in the rectangular groove, and a vacuum insulation board is provided on the outdoor side of the curtain wall panel and the concrete substrate, wherein the vacuum insulation board is used to provide excellent thermal insulation performance.

[0006] Preferably, horizontal connectors and load-bearing connector holes are provided in the concrete base plate, and two groups of load-bearing connector holes are provided for inserting load-bearing members extending from the main floor slab of the building.

[0007] Preferably, a window opening can be provided in the area between the curtain wall panel and the frame of the concrete base plate according to the design scheme.

[0008] Preferably, the vacuum insulation panels are fully laid on the outdoor side of the concrete base plate to ensure that condensation and mildew will not occur inside the wall due to thermal bridges.

[0009] Preferably, pre-embedded horizontal connectors and holes for inserting load-bearing connectors are arranged on the inner side of the concrete base plate, a limited steel plate member is provided on the top surface of the hole, and the frame where the hole is located is wider than other frames.

[0010] Preferably, the concrete substrate as the structural substrate has a plurality of rectangular grooves arranged in an array, the interior of the concrete substrate is a single-layer steel mesh, and the interior of the frame of the concrete substrate is a three-dimensional double-layer steel mesh integrated with the substrate steel bars.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model compounds the surface material of the curtain wall and the inner and outer insulation layers one by one onto a concrete base plate with grooves in the factory. The batch processing has high quality and the cost is lower than the on-site assembly installation of manually pasting the insulation layer and the decorative layer on the construction site. It does not require temporary brackets and pouring concrete construction, and does not require the high precision required for sleeve connection and bolt connection. Its load-bearing plug-in hole structure reduces the difficulty of installation and realizes the convenient installation of "hanging curtain cloth".

[0013] 2. The utility model uses reinforced concrete as the main material, wherein the integrated three-dimensional steel mesh is combined with concrete to be strong and durable, and is suitable for unit curtain walls with larger areas. No steel frame reinforcement ribs are required inside the concrete, thus reducing the risk of thermal bridges. This curtain wall panel is directly installed on the main body of the building without laying metal keels and waterproof vapor barrier structures, thus saving material and construction costs compared to conventional opaque curtain wall methods.

[0014] 3. The utility model is fully covered with vacuum insulation panels on the outside, without thermal bridges. The vacuum insulation panels are only 10-30mm thick, which are thinner than traditional insulation materials and are not easy to fall off. In addition, the vacuum insulation panels made of Class A fireproof materials can reduce the fire hazard of exterior wall insulation projects, save the concrete outer layer of conventional assembled sandwich concrete wall panels, and reduce the weight. The thicker traditional insulation layer on the inside is cast and formed in one piece with the concrete groove, which avoids the risk of exterior wall insulation falling off and the risk of vacuum insulation panels being squeezed and damaged at the junction with the floor when arranged on the first floor of the room. The inner and outer insulation layers work together to achieve the relevant standards of the heat transfer coefficient of the exterior wall of ultra-low energy consumption buildings. When designing the curtain wall, this insulation layer can use different materials, thicknesses and bulk densities to suit the exterior wall heat transfer coefficient standards of different regions. In this way, the thickness of the more expensive vacuum insulation panels on the outside of the curtain wall can be finely adjusted to the highest cost-effectiveness. The heat storage performance of the concrete curtain wall is higher than that of the curtain wall made of lightweight insulation materials, the indoor temperature difference is stable, and the comfort level is high.

[0015] 4. Compared with the existing curtain wall made of composite insulation board materials, the curtain wall of the utility model has a strong structure, low material cost, and high thermal insulation and corrosion resistance. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 , Figure 2 and Figure 3 An ultra-low energy consumption building curtain wall includes a curtain wall panel 3 and a concrete substrate 5. The curtain wall panel 3 is provided with a concrete substrate 5. The concrete substrate 5 is provided with a rectangular groove. An insulation board 6 is embedded in the rectangular groove. A vacuum insulation panel 7 is provided on the outdoor side of the curtain wall panel 3 and the concrete substrate 5. The vacuum insulation panel 7 is used to provide excellent thermal insulation performance.

[0022] When using an ultra-low energy consumption building curtain wall, a plurality of rectangular grooves are arranged in an array in the concrete substrate 5 serving as the structural substrate. The interior of the concrete substrate 5 is a single-layer steel mesh. The interior of the frame of the concrete substrate 5 is a three-dimensional double-layer steel mesh integrated with the substrate steel bars. Since the interior of the vacuum insulation panel 7 is in a vacuum state, there is almost no possibility of heat conduction by gas, so the heat transfer can be significantly reduced, effectively isolating the temperature difference between indoor and outdoor.

[0023] The insulation board 6 and the concrete base plate 5 are cast in one piece, and there is no risk of falling off.

[0024] When designing the curtain wall, the insulation board 6 can be made of different materials, thicknesses and bulk densities to suit the exterior wall heat transfer coefficient standards of different regions, thereby finely adjusting the thickness and cost-effectiveness of the more expensive vacuum insulation board 7 on the outside of the curtain wall.

[0025] See also Figure 1 , Figure 2 and Figure 3 , horizontal connectors 1 and load-bearing connector holes 4 are provided in the concrete base plate 5, and two groups of load-bearing connector holes 4 are provided for inserting load-bearing members extending from the main floor of the building.

[0026] The inner side of the concrete base plate 5 is arranged with embedded horizontal connectors 1 and holes 4 for inserting load-bearing connectors. The top surface of the hole is provided with a limited steel plate member 8. The frame where the hole is located is wider than other frames. While strengthening the mechanical properties of the unitized curtain wall, a certain width and height are ensured to set the holes 4 for inserting load-bearing connectors, thereby ensuring that the curtain wall itself is not provided with load-bearing connectors. The embedded structure of the load-bearing connectors in the floor slab also becomes simple and does not need to be higher than the ground surface layer.

[0027] The portion between the curtain wall panel 3 and the frame of the concrete base plate 5 can be provided with a window opening 2 according to the design scheme.

[0028] The method of processing curtain wall panels is as follows: the insulation board 6 on the inner side of the building curtain wall is cut into several rectangular blocks, and after inserting insulation nails, they are arranged horizontally in the curtain wall mold according to the designed position. The curtain wall panel outer frame mold, the window opening mold and the insulation board 6 therein together constitute a mold of a concrete base plate with a groove. Then the three-dimensional steel mesh is placed in the mold, and steel pads are arranged at the same time. Hanging parts, connectors, embedded parts, wire sleeves and junction boxes are fixed on the steel mesh, concrete is poured, vibrated and cured, the vacuum insulation board 7 is bonded, insulation nails are inserted, glass fiber mesh is laid, plastering is performed, and real stone paint is sprayed.

[0029] The process of installing curtain wall panels: hoist the curtain wall panels 3, place them on the load-bearing connectors embedded in the building floor, adjust the height of the load-bearing connector bolts and adjust the horizontal connectors 1 until the exterior wall is flat, then fix the connectors, seal the indoor horizontal gaps with cement mortar, fill the vertical gaps with polyurethane foam glue, apply anti-cracking tape, stuff foam rods in the outdoor gaps between the curtain wall panels 3, apply weather-resistant glue, and the surface layers inside and outside the curtain wall are determined according to the architectural design plan, which is a conventional practice. For example, the indoor wall can be installed with joinery board keels and bamboo fiberboard veneers.
