Description

Technical Field

[0001] The utility model relates to the technical field of wall panels, in particular to an assembled external wall panel. Background Art

[0002] At present, the construction industry focuses on the production of wall panels. Traditional wall panels such as autoclaved lightweight aerated concrete partition walls (referred to as ALC panels) are prone to cracking and breakage, have high construction costs, and lack an efficient and convenient connection method for external wall panels.

[0003] Existing installation processes such as stone dry hanging have a single function and high construction costs, and are high-risk operations. For example, the existing practices of curtain walls such as stone and ceramic panels are all on-site construction, which are high-risk operations, relatively cumbersome, time-consuming and laborious, and will also result in uneven final quality. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the utility model provides an assembled external wall panel, which can not only ensure quality but also ensure safety, and the installation process is efficient and fast.

[0005] The technical solution for the utility model to solve the above technical problems is as follows:

[0006] An assembled external wall panel includes a main keel. One side of the main keel is provided with an inner wall panel, and the other side is provided with a plurality of sequentially connected outer wall panels; one end of each outer wall panel is provided with an assembly block, and the other end is provided with an assembly groove; the assembly block of the outer wall panel is embedded in the assembly groove of another outer wall panel and is installed on the main keel through a connection component, and a sealing caulking strip is provided at the joint of two adjacent outer wall panels.

[0007] By adopting the above technical solution, after the assembly block of one outer wall panel is embedded in the assembly groove of another outer wall panel, it is installed on the main keel through a connection component, so that the rapid installation of two adjacent outer wall panels can be realized, and then the sequential installation of multiple outer wall panels can be realized. The above installation process can be made in a factory, operated on the ground, and formed at one time. There is only one hoisting and installation process on site, which can not only ensure quality but also ensure safety, and the installation process is efficient and fast; the sealing caulking strip can seal the joint of two adjacent outer wall panels, play a waterproof and moisture-proof effect, and extend the service life of the assembled external wall panel.

[0008] Further, a secondary keel is provided on the main keel, an installation groove is provided on the assembly groove, and the connection component includes a dry hanging piece and a connection bolt. One end of the dry hanging piece abuts against the assembly block and is embedded in the installation groove adjacent to the assembly block; the other end of the dry hanging piece passes through the joint of two adjacent outer wall panels and is installed on the secondary keel through a connection bolt.

[0009] By adopting the above technical solution, one end of the dry hanging piece is abutted against the assembly block of one of the exterior wall panels, and the other end is fitted to the secondary keel. Then, the end of the dry hanging piece away from the secondary keel is inserted into the installation groove of the other exterior wall panel. Finally, the dry hanging piece is installed on the secondary keel through the connecting bolts, and the connection of two adjacent exterior wall panels can be realized.

[0010] Furthermore, a sealing gasket is provided at the abutting portion between the dry hanging piece and the assembly block, and the sealing gasket is used to seal the dry hanging piece and the exterior wall panel.

[0011] By adopting the above technical solution, the sealing gasket can seal the connection between the dry hanging piece and the two adjacent exterior wall panels, further achieving the effects of waterproofing and moisture-proofing.

[0012] Furthermore, the sealing gasket is made of rubber.

[0013] By adopting the above technical solution, the rubber sealing gasket has properties such as oil resistance, acid and alkali resistance, cold and heat resistance, and aging resistance, with better effects and longer service life.

[0014] Furthermore, a waterproof coating is provided on the side of the exterior wall panel facing the main keel.

[0015] By adopting the above technical solution, the waterproof coating can act as a waterproof barrier, further extending the service life of the prefabricated external wall panel.

[0016] Furthermore, the waterproof coating is polymer cement waterproof coating.

[0017] By adopting the above technical solution, the polymer cement waterproof coating has characteristics such as water resistance, no milk return, no swelling, non-toxic, and pollution-free, and belongs to an environmentally friendly waterproof coating product.

[0018] Furthermore, the sealing caulking strip is a silicone sealant strip.

[0019] By adopting the above technical solution, the silicone sealant has strong adhesion and large tensile strength, and at the same time has characteristics such as weather resistance, earthquake resistance, moisture-proofing, anti-odor, and adaptability to large temperature changes, and has a better sealing effect on the connection between two adjacent exterior wall panels.

[0020] Furthermore, rock wool and foam concrete are sequentially filled between the interior wall panel and the exterior wall panel, and the rock wool is arranged close to the interior wall panel.

[0021] By adopting the above technical solution, cold bridges in the wall panels are avoided, the heat preservation performance of the prefabricated external wall panel is ensured, and a prefabricated multi-functional integrated external wall panel that simultaneously meets functions such as heat preservation, fire prevention, waterproofing, and energy conservation is obtained, with relatively high comprehensive performance.

[0022] Further, a distance is left between the inner wall panel and the main keel, and a rubber pad is provided between the inner wall panel and the main keel. The inner wall panel, the rubber pad and the main keel are connected by screws.

[0023] By adopting the above technical solution, since the hardness of the rock wool thermal insulation material is insufficient and the direct bolting connection between the inner wall panel and the main keel is not flat enough, a rubber pad with a certain hardness is used for leveling.

[0024] Further, the outer wall panel is a ceramic panel, a nano stone wall panel or an aluminum plate.

[0025] By adopting the above technical solution, the ceramic panel has the characteristics of being green, environmentally friendly, radiation-free, with a mild color and no light pollution; the nano stone wall panel has the characteristics of fire prevention, waterproofing, corrosion resistance and no cracking; the aluminum plate wall panel has the characteristics of waterproofing, moisture-proofing, good fire resistance, good durability and easy cleaning.

[0026] In summary, compared with the prior art, the beneficial effects of the above technical solution are as follows:

[0033] The following is combined with the attachedFigure 1-2 The principles and features of the present utility model are described. The examples given are only used to explain the present utility model and are not intended to limit the scope of the present utility model.

[0034] An embodiment of the present utility model discloses an assembled external wall panel.

[0035] Referring to Figure 1 and Figure 2 , an assembled external wall panel includes a main keel 1. One side of the main keel 1 is provided with an inner wall panel 2, and the other side is provided with a plurality of sequentially connected external wall panels 3. Adjacent two external wall panels 3 are installed on the main keel 1 through a connecting component 6, thereby realizing the sequential installation of a plurality of external wall panels 3, which can not only ensure the quality but also ensure the safety, and the installation process is efficient and fast.

[0036] The external wall panel 3 is a ceramic board, a nano-stone wall panel or an aluminum plate. In this embodiment, a ceramic board is adopted, which has the characteristics of environmental protection, no radiation, mild color and no light pollution.

[0037] The side of the external wall panel 3 facing the main keel 1 is coated with a waterproof coating 11. The waterproof coating 11 has the effect of a waterproof barrier and can extend the service life of the assembled external wall panel. Specifically, the waterproof coating 11 is a polymer cement waterproof coating, which has the characteristics of water resistance, no milk return, no swelling, non-toxic and pollution-free, and belongs to an environment-friendly waterproof coating product.

[0038] One end of each external wall panel 3 is integrally connected with an assembly block 4, and the other end is provided with an assembly groove 5. After the assembly block 4 of one external wall panel 3 is embedded into the assembly groove 5 of another external wall panel 3 and then installed on the main keel 1 through the connecting component 6, the rapid installation of adjacent two external wall panels 3 can be realized, and further the sequential installation of a plurality of external wall panels 3 can be realized.

[0039] A secondary keel 8 is fixedly arranged on the main keel 1, and a mounting groove 9 is formed in the assembly groove 5. The connecting assembly 6 includes a dry hanging piece 61 and a connecting bolt 62. One end of the dry hanging piece 61 abuts against the assembly block 4 and is embedded in the mounting groove 9 adjacent to the assembly block 4; the other end of the dry hanging piece 61 passes through the joint of two adjacent exterior wall panels 3 and is installed on the secondary keel 8 through the connecting bolt 62. Specifically, during the installation process, first, one end of the dry hanging piece 61 abuts against the assembly block 4 of one of the exterior wall panels 3, and the other end is attached to the secondary keel 8. Then, the end of the dry hanging piece 61 away from the secondary keel 8 is embedded in the mounting groove 9 of the other exterior wall panel 3. Finally, the screw rod of the connecting bolt 62 passes through the secondary keel 8 and the dry hanging piece 61 in sequence, and the nut of the connecting bolt 62 is tightened, so that the dry hanging piece 61 can be installed on the secondary keel 8 through the connecting bolt 62, realizing the connection of two adjacent exterior wall panels 3. Moreover, gaskets can be installed between the head of the connecting bolt 62 and the secondary keel 8, and between the dry hanging piece 61 and the nut of the connecting bolt 62.

[0040] A sealing gasket 10 is fixedly arranged at the abutting position of the dry hanging piece 61 and the assembly block 4. The sealing gasket 10 can seal the joint between the dry hanging piece 61 and two adjacent exterior wall panels 3, playing the role of waterproofing and moisture-proofing. Specifically, the sealing gasket 10 is made of rubber material. The rubber sealing gasket 10 has properties such as oil resistance, acid and alkali resistance, cold and heat resistance, and aging resistance, with better effects and longer service life.

[0041] A sealing caulking strip 7 is fixedly arranged at the joint of two adjacent exterior wall panels 3 and away from the main keel 1, which can seal the joint of two adjacent exterior wall panels 3, playing the role of waterproofing and moisture-proofing, and extending the service life of the prefabricated exterior wall panel. Specifically, the sealing caulking strip 7 is a silicone sealant strip. The silicone sealant has strong adhesion and large tensile strength, and at the same time has characteristics such as weather resistance, earthquake resistance, moisture-proofing, anti-odor, and large adaptability to cold and heat changes, with better sealing effect on the joint of two adjacent exterior wall panels 3.

[0042] Rock wool 12 and foam concrete 13 are filled in sequence between the interior wall panel 2 and the exterior wall panel 3, that is, the rock wool 12 and the foam concrete 13 are fully paved between the interior wall panel 2 and the exterior wall panel 3, wrapping the main keel 1 and the secondary keel 8 therein, and the rock wool 12 is arranged close to the interior wall panel 2, avoiding cold bridges in the wall panel, ensuring the heat preservation performance of the prefabricated exterior wall panel, and obtaining a prefabricated multi-functional integrated exterior wall panel with high comprehensive performance that simultaneously meets functions such as heat preservation, fire prevention, waterproofing, and energy saving.

[0043] A distance is left between the exterior wall panel 3 and the main keel 1, and a distance is left between the interior wall panel 2 and the main keel 1. Since the hardness of the rock wool 12 thermal insulation material is insufficient, it is not flat enough for the interior wall panel 2 to be directly bolted to the main keel 1. Therefore, a rubber pad 14 is fixedly arranged between the interior wall panel 2 and the main keel 1. A screw 15 is commonly installed on the interior wall panel 2, the rubber pad 14 and the main keel 1, that is, the screw 15 sequentially passes through the interior wall panel 2, the rubber pad 14 and the main keel 1 to realize the installation of the interior wall panel 2.

[0044] The implementation principle of an assembled external wall panel in an embodiment of the present utility model is as follows: During the installation process, first place one side of two exterior wall panels 3 close to the main keel 1, and make one end of the dry hanging piece 61 abut against the assembly block 4 of one of the exterior wall panels 3, and the other end fit against the secondary keel 8. Then, embed the end of the dry hanging piece 61 far from the secondary keel 8 into the installation groove 9 of the other exterior wall panel 3. Finally, the screw rod of the connecting bolt 62 sequentially passes through the secondary keel 8 and the dry hanging piece 61, and tighten the nut of the connecting bolt 62, so that the dry hanging piece 61 can be installed on the secondary keel 8 through the connecting bolt 62 to realize the connection of two adjacent exterior wall panels 3, and fill a sealing caulking strip 7 at the joint of two adjacent exterior wall panels 3; repeat the above process to realize the installation of multiple exterior wall panels 3; place the other side of the interior wall panel 2 close to the main keel 1, fix the rubber pad 14 between the interior wall panel 2 and the main keel 1, and sequentially pass the screw 15 through the interior wall panel 2, the rubber pad 14 and the main keel 1 to realize the installation of the interior wall panel 2; finally, fill the rock wool 12 and the foam concrete 13 between the interior wall panel 2 and the exterior wall panel 3 in sequence, that is, the rock wool 12 and the foam concrete 13 are fully paved between the interior wall panel 2 and the exterior wall panel 3 to wrap the main keel 1 and the secondary keel 8 therein, and the rock wool 12 is arranged close to the interior wall panel 2 to realize the assembly process of the assembled external wall panel.

[0045] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
