[0002] In the existing technology, a prefabricated building refers to a building in which a large number of on-site operation works in the traditional construction method are transferred to a factory. Building components and fittings (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory and transported to the building construction site, and then assembled and installed on-site through reliable connection methods. For the existing prefabricated thermal insulation exterior wall panels, adhesives such as glue are usually used to paste the thermal insulation exterior wall panels on the exterior wall during installation. After pasting, there will be relatively large gaps between each thermal insulation exterior wall panel. Rainwater will penetrate through the gaps between the thermal insulation exterior panels and damage the adhesive, affecting the fixing stability of the thermal insulation exterior panels and reducing the service life of the thermal insulation exterior panels. There are technical problems such as poor fixing stability after the existing prefabricated thermal insulation exterior wall panels are pasted and the service life is affected after rainwater penetration.

[0034] Embodiment 1:

[0035] AsFigures 1 to 3 As shown in the figure, a schematic diagram of an embodiment of an assembled building composite wall panel of the present invention includes a plurality of first mounting plates 1 and an outer covering part with a matching quantity. The plurality of first mounting plates 1 are connected to each other to form horizontal or vertical joints, and the outer covering part is connected to the corresponding first mounting plate 1 to cover the corresponding joints. Preferably, it further includes a heat preservation board 2, and the first mounting plate 1 is connected to the heat preservation board 2.

[0036] On at least a pair of opposite sides of the first mounting plate 1, mutually adaptable slots and plugs are respectively arranged. An elastic limiting structure is arranged in the slot. The elastic limiting structure includes a limiting block movably connected to the inner wall of the slot. The plug is provided with a limiting groove. When the plug is inserted into the corresponding slot, the limiting block can be engaged with the limiting groove to be fixed.

[0037] The elastic limiting structure further includes a spring damping mechanism. A sliding groove is opened on the side of the slot, and the limiting block is connected to the inner wall of the sliding groove through the spring damping mechanism.

[0038] Preferably, slots are arranged on both sides of the first mounting plate 1. The slot arranged on the first side of the first mounting plate 1 penetrates through the first mounting plate 1 to form a first plugging slot 4, and the plug arranged on the opposite side of the first side is a matching rod shape to form a first plugging rod 5. The first plugging rod 5 is provided with a first limiting groove 51. A first sliding groove 41 is opened on the side of the first plugging slot 4. A first elastic limiting structure is arranged in the first sliding groove 41. The first elastic limiting structure includes a first spring 42, a first damper and a first limiting block 43. The first limiting block 43 is connected to the inner wall of the first sliding groove 41 through the first spring 42. The first damper is arranged in the first spring 42. The first damper is used for slowing down the sliding speed of the first limiting block 43. When the first plugging rod 5 is inserted into the first plugging slot 4, the first limiting block 43 can be embedded into the first limiting groove 51 to be locked;

[0039] The number of slots arranged on the second side of the first mounting plate 1 is multiple and is arranged at intervals to form a split-type clamping slot 8. The plugs arranged on the opposite side of the second side are blocks 9 with a matching quantity and can correspond to the clamping slots 8 one by one. The first side is perpendicular to the second side. Each block 9 is provided with a second limiting groove 91. A second sliding groove 81 is opened on the side of each clamping slot 8. A second elastic limiting structure is arranged in each clamping slot 8. The second elastic limiting structure includes a second spring 82, a second damper and a second limiting block 83. The second limiting block 83 is connected to the inner wall of the second sliding groove 81 through the second spring 82. The second damper is arranged in the second spring 82. The second damper is used for slowing down the sliding speed of the second limiting block 83. When the block 9 is inserted into the corresponding clamping slot 8, the second limiting block 83 can be embedded into the second limiting groove 91 to be locked.

[0040] In this embodiment, the first mounting plates 1 are rectangular and can be quickly and accurately spliced with each other. The elastic limiting structure can avoid lateral or vertical displacement after splicing, thereby ensuring the stability of the first mounting plates 1 after installation.

[0041] In this embodiment, the outer covering part includes a first outer panel 3, which is staggeredly connected to the outside of the first mounting plate 1, and the first outer panel 3 is vertically staggered with the first mounting plate 1, and the edge of the first outer panel 3 extends beyond the corresponding joint. The vertical staggered design allows the first outer panel 3 to cover the joint formed by the vertical splicing of adjacent first mounting plates 1 to achieve rainproof shielding protection, and the first outer panel 3 is horizontally staggered with the first mounting plate 1 to cover the joint formed by the horizontal splicing of adjacent first mounting plates 1. The first outer panel 3 and the first mounting plate 1 can be an integrated structure or a split structure.

[0042] This embodiment can ensure that the first mounting plates 1 are connected to each other to form a whole after assembly, thereby improving the stability of the fixation effect. The staggered design of the outer covering part can form shielding and protection for the joints, thereby increasing the service life of the combined wall panels.

[0043] Embodiment 2:

[0044] like Figures 4 to 5 As shown, compared with embodiment 1, this embodiment further includes a second mounting plate 6, one side or both sides of the first mounting plate 1 are connected to the second mounting plate 6 and form a thickness difference, and the first mounting plate 1 has a splicing surface 11 with a matching shape on the side opposite to the side connected to the second mounting plate 6. In this embodiment, the first mounting plate 1 and the second mounting plate 6 are an integrated structure.

[0045] Preferably, the splicing surface 11 can be fitted with the corresponding surface of the second mounting plate 6. When the cross-section of the second mounting plate 6 is triangular, the splicing surface 11 is a corresponding inclined surface; when the second mounting plate 6 is trapezoidal or rectangular, the splicing surface 11 forms an adaptive stepped bite structure.

[0046] In this embodiment, the second mounting plate 6 and the corresponding splicing surface 11 of the first mounting plate 1 are fitted together to form an inclined or irregular complex splicing surface, and cooperate with the staggered shielding of the outer covering part so that rainwater can only penetrate from multiple different directions, thereby better preventing rainwater from penetrating into the joints, avoiding rainwater from damaging the adhesive on the wall side of the first mounting plate 6, and improving the service life of the composite wall panel.

[0047] Embodiment 3:

[0048] like Figures 6 to 8 As shown, compared with Embodiment 1 and Embodiment 2, in this embodiment, the first mounting plate 1 and the second mounting plate 6 are split structures.

[0049] In this embodiment, the first mounting plate 1 is provided with a connecting groove 10 which also penetrates through the first mounting plate 1 to form a second insertion groove. The connecting groove 10 and the first insertion groove 4 are arranged on the same side and side by side. The second mounting plate 6 is provided with a connecting member 61 which is rod-shaped and adapted to the second insertion groove to form a second insertion rod. The connecting member 61 is provided with a locking groove 62. An elastic locking structure is arranged in the connecting groove 10. The elastic locking structure includes a locking block 101 movably connected to the inner wall of the connecting groove 10, and also includes a third spring 102 and a third damper. A third sliding groove 103 is formed on the side of the connecting groove 10. The locking block 101 is connected to the inner wall of the third sliding groove 103 through the third spring 102. The third damper is arranged in the third spring 102 and is used to slow down the sliding speed of the locking block 101. When the connecting member 61 is inserted into the connecting groove 10, the locking block 101 can be engaged with the locking groove 62 to be fixed.

[0050] In this embodiment, the outer covering part includes a first outer plate 3 and a second outer plate 7. The first outer plate 3 is connected to the first mounting plate 1 in a staggered manner, and the second outer plate 7 is connected to the second mounting plate 6 in a staggered manner. The first outer plate 3 and the second outer plate 7 cooperate to cover the corresponding joint.

[0051] Preferably, the first insertion rod 5 and the connecting member 61 can be provided with limiting protrusions, such as in a T shape, and the shapes of the first insertion groove 4 and the second insertion groove are adapted and opened. In this embodiment, axial sliding fit and radial multiple constraints can be achieved, which can improve the splicing efficiency and quality of the first mounting plate 1 and ensure the stability after splicing.

[0052] In this embodiment, the shape of the second mounting plate 6 can be fitted into the gap formed between the adjacent first mounting plates 1 to be spliced. The second mounting plate 6 can also be used to block the joint of the adjacent first mounting plates 1 to form a first-level shielding. The first outer plate 3 and the second outer plate 7 are connected in a staggered manner to form a multi-module second-level shielding. The multi-module shielding can not only increase the water drainage path, but also better reduce the hidden danger of rainwater seepage affecting the adhesive.

[0053] On the other hand, the present invention also provides a construction method for an assembled building composite wall panel, including the following steps:

[0054] During construction, the corresponding insulation board 2 is first fixed by the foaming glue bonding method or the pre-embedding method. The connecting member 61 is slid into the connecting groove 10. During the insertion process, the connecting member 61 pushes the locking block 101 to slide into the third sliding groove 103, and the third spring 102 is compressed. When the connecting member 61 is inserted into the connecting groove 10 to a predetermined position, the locking groove 62 can correspond to the locking block 101 and release the compression limit of the third spring 102. The locking block 101 is driven by the restoring force of the third spring 102 to insert into the locking groove 62, realizing the connection and fixation of the first mounting plate 1 and the second mounting plate 6.

[0055] In a construction scenario, two first mounting plates 1 are spliced. The first mounting plate 1 is rectangular and its first side is disposed below. When multiple first mounting plates 1 are assembled vertically, the first insertion rod 5 is inserted into the first insertion slot 4. During the insertion process, the first insertion rod 5 pushes the first limiting block 43 to slide into the first sliding slot 41, and the first spring 42 is compressed. When the first insertion rod 5 is inserted into the first insertion slot 4 to a predetermined position, the first limiting slot 51 can correspond to the first limiting block 43 and release the compression limit on the first spring 42. The first limiting block 43 slides and inserts into the first limiting slot 51 under the driving of the restoring force of the first spring 42, realizing the vertical splicing and locking of the vertical displacement of adjacent first mounting plates 1.

[0056] When multiple first mounting plates 1 are assembled horizontally, a plurality of clamping blocks 9 provided on one first mounting plate 1 are aligned with a plurality of clamping slots 8 provided on another first mounting plate 1, and the clamping blocks 9 are inserted into the corresponding clamping slots 8. During the insertion process, the clamping block 9 pushes the second limiting block 83 and causes the second limiting block 83 to slide into the second sliding slot 81 and compress the second spring 82. When the clamping block 9 is inserted into the clamping slot 8 to a predetermined position, the second limiting slot 91 can correspond to the second limiting block 83, and the compression limit of the second spring 82 is released. The second limiting block 82 inserts into the second limiting slot 81, realizing the horizontal splicing and locking of the horizontal displacement of adjacent first mounting plates 1.

[0057] The first outer plate 3 and the second outer plate 7 are arranged in a staggered manner after assembly and can block each corresponding joint in the horizontal or vertical direction, preventing rainwater from seeping in and affecting the service life.

[0058] The present invention can ensure the stability of the connection after the first mounting plates 1 are spliced together through the elastic limiting structure and the elastic locking structure. The first outer plate 3 and the second outer plate 7 are arranged in a staggered manner to block the splicing gaps, and the multi-directional misaligned covering structure prevents rainwater from seeping into the gaps, improving the service life of the assembled building composite wall panel.

[0059] The above has described the embodiments of the present invention in detail, but the content described is only the preferred embodiments of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
