Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of prefabricated exterior wall panels, specifically a prefabricated integrated thermal insulation exterior wall panel. Background Technology
[0002] With economic development, prefabricated building technology has matured, enabling standardized design of building components, factory processing, and on-site assembly. This construction method saves manpower and resources, shortens the construction cycle, and improves project quality. In prefabricated buildings, the form and characteristics of the exterior wall panels have a significant impact on project cost, construction difficulty, building safety, and comfort.
[0003] The existing technology has the following shortcomings: The existing technology, disclosed in publication number CN214364215U, discloses a prefabricated integrated wall panel suitable for steel structure external enclosure systems, "including an insulation layer, a structural layer, and a finishing layer; the structural layer is a thin reinforced concrete slab with pre-embedded connecting steel plates, which are fixedly connected to the steel beams of the steel structure through wall panel connectors; the insulation layer is bonded to the structural layer with concrete during fabrication and fixed with insulation layer anchor nails; the finishing layer includes ceramic tiles, facing bricks or cement interface mortar, mesh fabric, waterproof mortar, and exterior wall coating."
[0004] When using the aforementioned prefabricated integrated wall panels, the structural layer thickness becomes quite thick when the floor height is large, significantly increasing the self-weight of the wall panels. Since the insulation and structural layers are still fixed using adhesive-anchor combinations, there is a risk of detachment. Traditional prefabricated integrated wall panels use lightweight concrete or light steel keel as the main load-bearing components, with the insulation material fixed to the outside of the wall panel or sandwiched in the middle using adhesive-anchor combinations. This results in low overall wall panel strength, significant thickness, unreliable connection performance between insulation and structure, and an inability to achieve the same lifespan for both insulation and structure.

[0007] As a further preferred embodiment of this technical solution, the exterior wall panel includes a structural layer, a first insulation layer, a second insulation layer, multiple sets of insulation anchors, multiple sets of L-shaped fasteners, multiple sets of bolts, two sets of embedded steel plates, and two sets of nut sleeves. The structural layer is a thin reinforced concrete ribbed beam slab. The first insulation layer is embedded in a groove on the surface of the structural layer. The second insulation layer is glued to the outside of the first insulation layer. Multiple sets of insulation anchors are installed through the second insulation layer and the first insulation layer. Multiple sets of L-shaped fasteners are symmetrically arranged at the top and bottom of the side wall of the structural layer. Multiple sets of bolts are installed through the L-shaped fasteners. Two sets of embedded steel plates are embedded at the bottom of the side wall of the structural layer. Two sets of nut sleeves are embedded at the top of the side wall of the structural layer.
[0008] As a further preferred embodiment of this technical solution, the height of the structural layer is consistent with the vertical height of the exterior wall panel, and the first insulation layer and the second insulation layer are fixedly connected together by insulation anchors.

[0012] This utility model provides a prefabricated integrated thermal insulation exterior wall panel, which has the following beneficial effects:
[0013] This invention employs a reinforced concrete ribbed beam thin-plate design in the structural layer. The ribbed beams improve structural rigidity and strength, reduce the thickness of the exterior wall panel, and lower the overall weight of the exterior wall panel. Insulation layers one and two significantly improve the thermal insulation performance of the exterior wall panel, meeting the parameter requirements of ultra-low energy consumption buildings.

The structural layer 2 is a reinforced concrete ribbed beam slab. The first insulation layer 3 is embedded in a groove on the surface of the structural layer 2. The second insulation layer 4 is adhered to the insulation layer by adhesive. On the outside of layer 3, multiple sets of insulation anchors 5 are installed inside insulation layer 4 and insulation layer 3. Multiple sets of L-shaped fasteners 6 are symmetrically arranged at the top and bottom of the side wall of structural layer 2. Multiple sets of bolts 7 are installed inside the L-shaped fasteners 6. Two sets of embedded steel plates 8 are embedded at the bottom of the side wall of structural layer 2. Two sets of nut sleeves 9 are embedded at the top of the side wall of structural layer 2. The height of structural layer 2 is consistent with the vertical height of the exterior wall panel. The standard horizontal width is 3 meters, and the horizontal width of non-standard parts can be adjusted according to the column spacing and opening size. Insulation layer 3 and insulation layer 4 are fixedly connected together by insulation anchors 5. Layer 3 uses a Class B fire-rated insulation board, while layer 4 uses a Class A fire-rated insulation board. The L-shaped fastener 6 is connected to the main structural beam 1 by bolts 7, with corresponding bolts 7 and nut sleeves 9. The L-shaped fastener 6 is welded to the embedded steel plate 8, and mounting holes are provided on its surface. During the pouring of structural layer 2, insulation layer 3 is embedded in the grooves on the surface of structural layer 2, while the nut sleeves 9 and embedded steel plates 8 are embedded at the four corners inside structural layer 2, completing integrated pouring and fixing.

After pouring structural layer 2, insulation layer 4 is glued together with insulation layer 3 and the ribs of structural layer 2. Finally, insulation anchors 5 are used to simultaneously anchor insulation layer 3 and insulation layer 4 to structural layer 2, thus completing the assembly of the exterior wall panel. The ribs improve structural rigidity and strength, reduce the thickness of the exterior wall panel, and also reduce the overall weight of the exterior wall panel. The insulation layer 3 and insulation layer 4 can significantly improve the thermal insulation performance of the exterior wall panel. The insulation layer 3, insulation layer 4 and structural layer 2 are connected by embedding, anchoring and bonding, which improves the reliability of the connection. When installing the exterior wall panel, the L-shaped fastener 6 is fixed to the outside of the main structural beam 1 by bolts 7, and then the bolts 7 are inserted into the nut sleeve 9 to complete the installation and fixation of the L-shaped fastener 6 to the top of the structural layer 2. Finally, the L-shaped fastener 6 is welded to the embedded steel plate 8 to complete the installation and fixation of the L-shaped fastener 6 to the bottom of the structural layer 2, thereby completing the installation and fixation of the main structural beam 1 and the exterior wall panel. The installation is convenient and the connection is stable, reducing the risk of falling off.
