Technical Field

[0001] This utility model relates to the field of building exterior wall technology, specifically to an exterior wall panel for prefabricated buildings. Background Technology

[0002] Building exterior walls are the external enclosure structure of a building, mainly responsible for functions such as protection, heat insulation, waterproofing, and sound insulation.

[0003] A Chinese patent with publication number CN208518129U discloses a building exterior wall, including a first outer layer brick and a first inner layer brick. The first outer layer brick is disposed on the outside of the wall, and the first inner layer brick is disposed on the inside of the wall. A water seepage channel is provided between the first outer layer brick and the first inner layer brick. The width of the water seepage channel is 30-60mm. This building exterior wall solves the problem of water seepage in exterior walls, and the wall has good thermal insulation and sound insulation effects.

[0004] The above-mentioned scheme and existing technology for building exterior wall construction usually include the first step of wall masonry or formwork pouring of concrete walls, and the second step of insulation layer plastering construction. The process is complicated and consumes a lot of manpower and time. There is a lack of corresponding prefabricated building exterior wall structures that combine wall construction and insulation layer construction in one quick construction, which needs to be improved and optimized. Utility Model Content

[0005] The purpose of this utility model is to provide an exterior wall panel for prefabricated buildings to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an exterior wall panel for prefabricated buildings includes a concrete outer panel, a steel mesh fixedly connected inside the concrete outer panel, a connecting rod fixedly connected to one end of the steel mesh, an insulation interlayer penetrating the middle of the connecting rod, another steel mesh fixedly connected to the other end of the connecting rod, a locking strip fixedly connected to one end of the concrete outer panel, and a groove provided at the other end of the concrete outer panel, with a locking component provided in the groove.

[0007] Preferably, the concrete outer panel consists of two sets symmetrically connected to both ends of the insulation interlayer.

[0008] Preferably, a wire mesh is fixedly connected to the middle of the insulation interlayer, a perforated plate is fixedly connected to the middle of the wire mesh, and the middle of the connecting rod is inserted into the perforated plate.

[0009] Preferably, the card strip has a locking hole in the middle.

[0010] Preferably, the locking component includes a pin groove, which is located at one end of the wire groove. A locking pin is inserted into the pin groove. A connecting block is fixedly connected to one end of the locking pin. A spring is fixedly connected to one end of the connecting block. A locking handle is fixedly connected to the other end of the connecting block. One end of the spring is fixedly connected to the inner wall of the pin groove.

[0011] Preferably, a locking adjustment block is rotatably inserted into the middle of the pin groove, and one end of the locking adjustment block is provided with a first slot and the other end of the locking adjustment block is provided with a second slot.

[0012] Preferably, the first slot can be engaged with the locking handle, and the second slot can be engaged with the locking handle.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model proposes a prefabricated building exterior wall panel that integrates an insulation layer by connecting two concrete outer panels with an insulation interlayer in between. This avoids the complex process of plastering and applying an insulation layer after the exterior wall construction is completed. The panel is fixed by inserting clips and grooves between the upper and lower concrete outer panels and locking pins of locking components, enabling rapid on-site assembly of the building exterior wall panel. This avoids the complex process of on-site formwork and concrete construction. This prefabricated building exterior wall panel optimizes the construction process and greatly saves manpower and time.

[0025] Example 1: An exterior wall panel for prefabricated buildings includes a concrete outer panel 1, with a steel mesh 2 fixedly connected inside the concrete outer panel 1. One end of the steel mesh 2 is fixedly connected to one end of a connecting rod 3, and an insulation interlayer 4 passes through the middle of the connecting rod 3. Another steel mesh 2 is fixedly connected to the other end of the connecting rod 3. A locking strip 5 is fixedly connected to one end of the concrete outer panel 1, and a wire groove 6 is provided at the other end of the concrete outer panel 1. A locking component is provided in the wire groove 6. The concrete outer panel 1 consists of two sets and is symmetrically connected to both ends of the insulation interlayer 4. A wire mesh 8 is fixedly connected to the middle of the insulation interlayer 4, and a perforated plate 9 is fixedly connected to the middle of the wire mesh 8. The middle of the connecting rod 3 is inserted into the perforated plate 9.

[0026] In use, the building exterior wall panel includes two sets of outer concrete panels 1 and an intermediate insulation interlayer 4. The concrete panels 1 are internally connected with steel mesh 2, and the insulation interlayer 4 is internally connected with wire mesh 8. Multiple sets of perforated plates 9 are fixedly connected to the middle of the wire mesh 8. Connecting rods 3 are inserted and fixed on the perforated plates 9 respectively. The two ends of the connecting rods 3 are inserted into the concrete panels 1 at both ends and welded to the steel mesh 2, so that the two outer concrete panels 1 tightly clamp the intermediate insulation interlayer 4, ensuring the overall stability of the structure.

[0027] Example 2: Based on Example 1, preferably, the locking strip 5 has a locking hole 10 in the middle; the locking component includes a pin groove 701, which is located at one end of the wire groove 6. A locking pin 702 is inserted into the pin groove 701. A connecting block 703 is fixedly connected to one end of the locking pin 702. A spring 704 is fixedly connected to one end of the connecting block 703. A locking handle 705 is fixedly connected to the other end of the connecting block 703. One end of the spring 704 is fixedly connected to the inner wall of the pin groove 701. A locking adjustment block 706 is rotatably inserted into the middle of the pin groove 701. A first locking groove 707 is provided at one end of the locking adjustment block 706, and a second locking groove 708 is provided at the other end of the locking adjustment block 706.

The locking strip 5 of the lower concrete outer panel 1 is aligned with the groove 6 of the upper concrete outer panel 1 to achieve quick insertion and assembly of the upper and lower building exterior wall panels. Then, pull the locking handle 705 on the upper concrete outer panel 1 outward to disengage the locking handle 705 from the first slot 707 on the locking adjustment block 706. Rotate the locking adjustment block 706 to align the second slot 708 with the locking handle 705. After releasing, the locking handle 705 is engaged into the second slot 708 under the restoring pull of the spring 704. Inside, the locking pin 702 is inserted into the locking hole 10 on the clip 5 on the lower concrete outer panel 1, thereby locking the clip 5 to the wire groove 6, thus assembling and fixing the upper and lower building exterior wall panels. When disassembly is required, simply pull the locking handle 705 on the upper concrete outer panel 1 again to disengage it from the second slot 708, and rotate the locking adjustment block 706 to align the first slot 707 with the locking handle 705.
