Description

Technical Field

[0001] This utility model relates to the field of fixed building technology, and in particular to a prefabricated exterior wall panel. Background Technology

[0002] Precast exterior wall panels refer to reinforced concrete slab components manufactured in prefabrication plants or construction sites for use in building assembly. They are also known as wall panels or cladding panels. Using precast concrete wall panels to construct prefabricated large-panel buildings can improve the degree of factory and mechanized construction, reduce on-site wet work, save on-site labor, overcome seasonal influences, and shorten the construction cycle.

[0003] However, in existing prefabricated exterior wall panels, large-sized panels are difficult to transport and install, while when small units are assembled, the wall panels need to be constructed simultaneously with the main structure, relying on temporary supports, making it difficult to achieve rapid independent installation.

[0020] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0021] refer to Figures 1 to 4 The present invention discloses the following embodiments: A prefabricated exterior wall panel includes a plurality of exterior wall panel units 1, which are connected vertically in sequence; and a supporting keel 2, which passes vertically through each of the exterior wall panel units 1, and the two ends of the supporting keel 2 are used to connect the wall and floor slabs and support the exterior wall panel units 1. The exterior wall panel unit 1 includes two prefabricated panels 101 arranged opposite each other. In this embodiment, they are an inner prefabricated panel 101 and an outer prefabricated panel 101. The upper and lower ends of the prefabricated panel 101 are provided with connecting structures. The connecting structures are used to connect adjacent exterior wall panel units 1 and to connect the supporting keel 2.

[0022] In this embodiment, during transportation, the supporting keel 2 and the exterior wall panel unit 1 can be packaged and transported separately, which facilitates packaging and transportation. During installation, the supporting keel 2 can be installed first (controlling the two ends of the supporting keel 2 to be connected to the floor slab and wall respectively), and then the exterior wall panel unit 1 can be installed on the supporting keel 2, without relying on the external temporary support structure, thus achieving rapid independent installation. In addition, during long-term use, the supporting keel 2 runs through all the exterior wall panel units 1, forming a continuous load-bearing structure, avoiding mutual displacement between the structures of each unit.

[0023] The connecting structure includes a first connecting plate 3. One end of the first connecting plate 3 passes between adjacent prefabricated leaf plates 101. Specifically, one end of the first connecting plate 3 is bolted to the supporting keel 2, and the other end extends vertically with a plug-in block 4. The lower end of the prefabricated leaf plate 101 is provided with a plug-in groove 102 that mates with the plug-in block 4. The upper end face of the first connecting plate 3 is used to support the bottom surface of the prefabricated leaf plate 101 above it. Specifically, after the supporting keel 2 is installed, the first connecting plate 3 is installed so that the plug-in block 4 of the first connecting plate 3 faces upward. Then, the prefabricated leaf plate 101 on this side is installed so that the plug-in groove 102 mates with the plug-in block 4. At this time, the first connecting plate 3 can play a supporting role to facilitate the installation of the prefabricated leaf plate 101.

[0024] The connecting structure includes a second connecting plate 5, which has a horizontal plate 501 and a vertical plate 502. The cross-section of the second connecting plate 502 is L-shaped and can be made of angle steel. The vertical plate 502 is attached to the inner wall of the upper end of the precast leaf plate 101 and is fixed and locked by a sleeve bolt 6. The horizontal plate 501 is bolted to the supporting keel 2. The sleeve of the sleeve bolt 6 is embedded in the precast leaf plate 101. After the insertion groove 102 at the lower end of the precast leaf plate 101 is engaged with the insertion block 4, the sleeve bolt 6 is then connected. The structure is simple and the connection is convenient.

[0025] The prefabricated leaf plate 101 is provided with connecting joints 7 at both the upper and lower ends. The connecting joints 7 are used to connect the first connecting plate 3 or the second connecting plate 5. The thickness of the connecting joints 7 is greater than the thickness of the main structure in the middle of the prefabricated leaf plate 101, thereby providing sufficient strength and space to accommodate the above-mentioned connecting structure.

[0026] The connecting joint 7 is provided with a reinforcing rib 8, which is a steel structure pre-embedded inside the connecting joint 7. The reinforcing rib 8 includes a horizontal reinforcing part 801 extending above the insertion groove 102 and a vertical reinforcing part 802 extending to one side of the insertion groove 102. The lower end of the vertical reinforcing part 802 abuts against the upper surface of the first connecting plate 3, so that the load of the vertical part of the prefabricated plate 101 is more directly transmitted to the first connecting plate 3.

[0027] A first sealing layer 9 is provided between the plug block 4 and the plug groove 102 to prevent water or air from seeping in through the plug groove 102.

[0028] A second sealing layer 10 is provided in the gap between the vertically adjacent prefabricated panels 101 to seal the horizontal joint between the vertically adjacent prefabricated panels 101.

[0029] The surface of the exterior wall panel unit 1 is also provided with a waterproof layer 11. Specifically, after installation, a GRC waterproof layer 11 is coated on the surface of the exterior wall panel unit 1 in this embodiment to provide an overall waterproof barrier for the exterior wall panel unit 1 and further prevent moisture from seeping into the interior of the exterior wall panel unit 1.

[0030] The supporting keel 2 includes a set of vertical keels 201 arranged vertically and a transverse keel 202 arranged between the set of vertical keels 201. The transverse keel 202 is used to connect the first connecting plate 3. Specifically, angle steel is provided (welded) on the transverse keel 202, and the angle steel is fixedly connected to the first connecting plate 3 by bolts.

[0031] The top and bottom exterior wall panel units 1 are provided with a connecting part 13 for connecting the wall and floor slab on the side away from the adjacent exterior wall panel units 1, as shown in the figure. The exterior wall panel units 1 with the connecting part are the top or bottom connected vertically in sequence, and are the outer prefabricated panels 101. The connecting part 13 has a connecting groove 12. An L-shaped connector 14 is provided on the connecting part 13. Part of the L-shaped connector 14 is inserted into the connecting groove 12, and the other part of the L-shaped connector 14 is fixedly connected to the outer end face of the wall and floor slab by expansion bolts.
