[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as being limited to the embodiments described herein. The same figure marks in the figures represent the same or similar structures, and thus their repeated descriptions will be omitted. The words expressing position and direction described in the embodiments of the utility model are all explained with reference to the accompanying drawings as examples, but changes can be made as needed, and the changes made are all included in the scope of protection of the utility model. The drawings of the embodiments of the utility model are only used to illustrate the relative position relationship, and they do not represent the true proportions.

[0020] It should be noted that specific details are described in the following description to facilitate understanding of the present invention. However, the present invention can be implemented in a variety of other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] The assembled exterior wall interlayer fireproof plugging is installed between the exterior wall and the main floor plate structure of the building, so as to effectively prevent the occurrence of smoke and fire between floors when a fire occurs. In the prior art, the assembled exterior wall interlayer fireproof plugging includes multiple layers of materials separated from each other. In the process of installing the assembled exterior wall interlayer fireproof plugging, the separated materials need to be installed layer by layer between the main floor plate structure of the building and the exterior wall to play a role in smoke and fire prevention. However, in actual applications, the installation efficiency of the above-mentioned assembled exterior wall interlayer fireproof plugging is low, and the dimensional consistency between the layers of the fireproof plugging obtained by layer-by-layer installation is poor, and the construction quality is related to the technical level of the on-site workers, which leads to a lack of controllability in the construction quality.

[0022] In view of this, the prefabricated exterior wall interlayer fire blocking provided by the utility model improves the installation efficiency and construction quality of the prefabricated exterior wall interlayer fire blocking by designing the prefabricated exterior wall interlayer fire blocking as an integrated component.

[0023] refer to Figure 1 , Figure 1 A structural schematic diagram of an assembled exterior wall interlayer fireproof plug provided for an embodiment of the utility model. The assembled exterior wall interlayer fireproof plug is installed between the exterior wall 02 and the main floor slab structure 01 of the building. The assembled exterior wall interlayer fireproof plug is an integrated component, and the assembled exterior wall interlayer fireproof plug includes a surface layer 1 and a core layer 2, wherein the surface layer 1 forms a receiving cavity 11, the core layer 2 is received in the receiving cavity 11, and the core layer 2 is fixedly connected to the receiving cavity 11. The assembled exterior wall interlayer fireproof plug provided by the utility model, by setting the assembled exterior wall interlayer fireproof plug as an integrated component, and the assembled exterior wall interlayer fireproof plug can be prefabricated and processed by the factory, so that the assembled exterior wall interlayer fireproof plug can be installed as a whole at the construction site, which is conducive to improving the installation efficiency and construction quality of the assembled exterior wall interlayer fireproof plug.

[0024] Continue to refer Figure 1 , the thickness of the core layer 2 is greater than or equal to 200 mm. In this way, while meeting the fire resistance requirements of the core layer 2, the manufacturing cost of the assembled exterior wall interlayer fire blocking can be reduced and its fire prevention effectiveness can be improved.

[0025] When selecting the material of the core layer 2, the present invention does not limit the specific material of the core layer 2. For example, the material of the core layer 2 can be rock wool or mineral wool. This can reduce the material cost while meeting the fire resistance requirements of the core layer 2. In addition, the bulk density of the rock wool is required to be in the range of 100-120 kg / cm 3 This is conducive to improving the fire prevention effectiveness of fire blocking between prefabricated exterior wall layers.

[0026] In the assembled exterior wall interlayer fireproof plugging provided by the utility model, the core layer 2 is bonded to the accommodating cavity 11. This is conducive to improving the processing convenience of the assembled exterior wall interlayer fireproof plugging. It is worth mentioning that the bonding strength between the core layer 2 and the accommodating cavity 11 formed by the surface layer 1 needs to be greater than 0.06Mpa, which is conducive to improving the connection reliability between the surface layer 1 and the core layer 2.

[0027] When the material of the surface layer 1 is specifically selected, in the present invention, the specific material of the surface layer 1 is not limited. For example, the surface layer 1 material can be a galvanized sheet or a stainless steel sheet; the surface layer material can also be a cement fiber pressurized board or a gypsum board, etc. And when the material of the surface layer 1 is a metal material, the thickness of the sheet is greater than or equal to 1.5 mm, so that the fire resistance time requirements of the interlayer fireproofing of the assembled exterior wall can be met while reducing the material cost.

[0028] It is worth mentioning that the exposed surface of the surface layer 1 away from the core layer 2 is provided with a spray coating, which can effectively improve the waterproof and mildew-proof properties of the surface layer 1, thereby extending the service life of the fire-proof sealing between the prefabricated exterior wall layers.

[0029] In addition, in the present invention, the specific shape of the fireproof plugging between the assembled external walls is not limited, and can be adjusted according to the thickness of the building floor and the spacing requirements between the two assembled external walls. For example, refer to Figure 2 , Figure 2 A schematic diagram of the structure of the outer wall interlayer fire blocking provided by the embodiment of the utility model. The shape of the assembled outer wall interlayer fire blocking can be strip-shaped or L-shaped. This can simplify the manufacturing process while ensuring the fireproof performance and reduce the manufacturing cost.

[0030] Continue to refer Figure 1 The assembled exterior wall interlayer fireproof plugging structural system includes a building main floor plate structure 01, an exterior wall 02, and an assembled exterior wall interlayer fireproof plugging. The assembled exterior wall interlayer fireproof plugging is arranged between the building main floor plate structure 01 and the exterior wall 02, wherein the assembled exterior wall interlayer fireproof plugging is fixedly connected to the building main floor plate structure 01; and the assembled exterior wall interlayer fireproof plugging abuts against the exterior wall 02; and the exterior wall 02 is fixedly connected to the building main floor plate structure 01. This is conducive to improving the connection reliability between the assembled exterior wall interlayer fireproof plugging and the building main floor plate structure 01, and improving the sealing and fire resistance between each floor.

[0031] It is worth mentioning that the main floor slab structure 01 of the building usually includes beams, slabs and columns. Since beams, slabs and columns are distributed in different positions of the main building according to construction requirements and their own functions and strengths, when the assembled external wall interlayer fire blocking is installed, when the assembled external wall interlayer fire blocking is located between the beam and the external wall 02, the assembled external wall interlayer fire blocking is connected to the beam; when the assembled external wall interlayer fire blocking is located between the slab and the external wall 02, the assembled external wall interlayer fire blocking is connected to the slab; when the assembled external wall interlayer fire blocking is located between the column and the external wall 02, the assembled external wall interlayer fire blocking is connected to the column. In this way, the outer wall between each floor of the main floor slab structure 01 of the building is provided with assembled external wall interlayer fire blocking between the external wall 02 to avoid the occurrence of fire and smoke between the floors, thereby effectively improving the sealing and safety between the floors.

[0032] It should be noted that, in the present invention, the board of the main floor board structure 01 is a building floor board, which is located between two adjacent floors and is used to separate the two floors. The building floor board includes a first board surface 011 and a second board surface 012 arranged opposite to each other, wherein the first board surface 011 is the ground of the higher floor of the two adjacent floors, and the second board surface 012 is the top surface of the lower floor of the two adjacent floors.

[0033] In addition, according to actual fire protection requirements, two layers of prefabricated exterior wall interlayer fire blocking can be set between the main floor plate structure 01 and the exterior wall 02 of the building along the direction from the first plate surface 011 to the second plate surface 012 to improve the fire protection effectiveness between each floor.

[0034] Since the outer circumferential dimension of the main floor plate structure 01 of the building is relatively large, a plurality of assembled exterior wall interlayer fire blockings need to be installed along the outer circumferential direction of the main floor plate structure 01 of the building to ensure the effectiveness of fire prevention between each floor. In the prior art, since a single assembled exterior wall interlayer fire blocking is installed layer by layer between the outer side wall of the main floor plate structure 01 of the building and the exterior wall 02, there are certain size differences between the assembled exterior wall interlayer fire blockings arranged at different positions of the main floor plate structure 01 of the building. The assembled exterior wall interlayer fire blocking provided by the utility model, by setting the assembled exterior wall interlayer fire blocking as an integrated component, can be installed as a whole at the construction site, which is conducive to improving the size consistency of the assembled exterior wall interlayer fire blockings arranged at different positions of the main floor plate structure 01 of the building, thereby effectively improving the effectiveness of fire prevention between each floor.

[0035] Continue to refer Figure 1, the surface layer 1 is fixedly connected to the main floor plate structure 01 of the building; and the surface layer 1 is in contact with the outer wall 02. This is conducive to improving the connection reliability between the assembled outer wall interlayer fireproof blocking and the main floor plate structure 01 of the building.

[0036] It is worth mentioning that, since the beams, plates and columns of the main floor plate structure 01 of the building are distributed at different positions of the main floor plate structure 01 of the building according to the construction requirements and their own functions and strengths, when installing the assembled external wall interlayer fire blocking, when the assembled external wall interlayer fire blocking is located between the beam and the external wall 02, the surface layer 1 is connected to the beam; when the assembled external wall interlayer fire blocking is located between the plate and the external wall 02, the surface layer 1 is connected to the plate; when the assembled external wall interlayer fire blocking is located between the column and the external wall 02, the surface layer 1 is connected to the column. This is conducive to improving the connection reliability and sealing between the assembled external wall interlayer fire blocking and the main floor plate structure 01 of the building.

[0037] It is worth mentioning that the sealant is filled between the surface layer 1 and the main floor plate structure 01 of the building; the sealant is filled between the surface layer 1 and the exterior wall 02. And the sealant is fireproof. This is conducive to further improving the sealing between the main floor plate structure 01 of the building and the fireproof sealing between the assembled exterior wall layers, and improving the sealing between the fireproof sealing between the assembled exterior wall layers and the exterior wall 02.

[0038] In the assembled exterior wall interlayer fireproof plugging construction system provided by the utility model, the surface layer 1 can be fixed to the main building floor plate structure 01 by riveting, clamping or nailing. When installing the assembled exterior wall interlayer fireproof plugging, the surface layer 1 can be directly connected to the main building floor plate structure 01 by riveting or nailing, which is conducive to improving the installation efficiency of the assembled exterior wall interlayer fireproof plugging. Alternatively, a buckle is provided on the side of the surface layer 1 close to the main building floor plate structure 01, and a hook is provided on the outer side wall of the main building floor plate structure 01, so as to realize the connection between the surface layer 1 and the main building floor plate structure 01 by the buckle and the hook being mutually clamped, which is conducive to improving the installation efficiency and later replacement efficiency of the assembled exterior wall interlayer fireproof plugging.

[0039] In addition, in the present invention, the exterior wall 02 is fixed to the main floor plate structure 01 of the building by riveting, clamping or nailing. When installing the exterior wall 02, the exterior wall 02 can be connected to the main floor plate structure 01 of the building by riveting or nailing, which is conducive to improving the installation efficiency of the exterior wall 02. Alternatively, a buckle is set on the side of the exterior wall 02 close to the main floor plate structure 01 of the building, and the buckle is directly clamped on the keel of the main floor plate structure 01 of the building, which is conducive to improving the installation efficiency and later maintenance efficiency of the exterior wall 02. It is worth mentioning that the buckle set on one side of the main floor plate structure 01 of the building can be fixed to the main floor plate structure 01 of the building by pre-embedding or on-site installation.

[0040] It is worth mentioning that the fireproofing between layers of the prefabricated exterior wall can be made of the same material as the exterior wall 02, which can effectively improve the utilization rate of the raw materials for the exterior wall or the fireproofing between layers of the prefabricated exterior wall, and facilitate the simultaneous production of the exterior wall 02 and the fireproofing between layers of the prefabricated exterior wall.

[0041] In a specific embodiment, the surface layer 1 of the assembled external wall interlayer fireproof plugging adopts a galvanized sheet with a thickness of 1.5 mm, and the core layer 2 adopts rock wool with a thickness of 200 mm, and the rock wool is accommodated in the accommodation cavity 11 formed by the galvanized sheet, and the rock wool is bonded to the accommodation cavity 11 of the galvanized sheet to obtain a composite assembled external wall interlayer fireproof plugging, and a spray coating is provided on the side of the surface layer 1 away from the core layer 2. This is conducive to further reducing the manufacturing cost while meeting the fire resistance requirements of the assembled external wall interlayer fireproof plugging.

[0042] After a preliminary understanding of the specific structure of the prefabricated exterior wall interlayer fire blocking structural system provided by the present invention, the construction process of the prefabricated exterior wall interlayer fire blocking structural system is further explained in combination with actual construction scenarios.

[0043] In the present invention, a keel frame is provided on the outer side wall of the main floor plate structure 01 of the building, and the outer wall 02 is fixed to the keel frame. When constructing the assembled exterior wall interlayer fireproof blocking structural system, the outer wall 02 is first installed on the keel frame, and then the integrated assembled exterior wall interlayer fireproof blocking is fixedly connected to the main floor plate structure 01 of the building, and the assembled exterior wall interlayer fireproof blocking is abutted against the exterior wall. Compared with the prior art, this can avoid the installation of assembled exterior wall interlayer fireproof blocking layer by layer at the construction site, which is conducive to improving the installation efficiency of assembled exterior wall interlayer fireproof blocking.

[0044] It is worth mentioning that when constructing the prefabricated exterior wall interlayer fire blocking structural system, the installation sequence of the exterior wall 02 and the prefabricated exterior wall interlayer fire blocking is not limited, and can be adjusted according to actual installation requirements.

[0045] The utility model provides a prefabricated exterior wall interlayer fire blocking structural system, which designs the prefabricated exterior wall interlayer fire blocking as an integrated component so that the prefabricated exterior wall interlayer fire blocking can be installed as a whole at the construction site, which is beneficial to improving the installation efficiency of the prefabricated exterior wall interlayer fire blocking.

[0046] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
