Description

Technical Field

[0001] The utility model relates to the technical field of building wall panels, and in particular to a light fireproof and heat-insulating composite panel. Background Art

[0002] The total carbon emissions of buildings throughout their life cycle account for 51.2% of the country's energy carbon emissions. The development of ultra-low energy consumption buildings has become a development trend in today's construction industry and an important goal of my country's construction industry at this stage. Currently, the frame structure products used in public buildings on the market are mainly the following three systems.

[0003] Thin plaster system: The insulation layer of this system is prone to falling off, the fire resistance is poor, and the insulation service life is only 25 years, which is inconsistent with the 50-year life of the building design;

[0004] Wire mesh composite board sandblasting and slurry exterior wall insulation system: This system sets a 3 cm perlite board + 3 cm spray coating as a protective layer on the outside of the filling wall insulation layer. The protective layer is connected to the insulation layer through connectors to achieve an integrated insulation structure, and the protection level can achieve structural A-level. Interlayer cantilevers are set between the building layers to avoid the problem of insulation falling off. The service life of the insulation system is 50 years, achieving the same life as the insulation structure. However, the insulation layer of the shear wall is combined with adhesive anchors. Although there is a 5 cm A-level fireproof structure on the outside, which solves the fire prevention problem, the problem of insulation falling off still needs to be improved;

[0005] Cast-in-place concrete built-in insulation system: This system sets a 5 cm protective layer on the outside of the shear wall and the infill wall. The protective layer is connected to the structural layer through connectors, and cantilevers are set between the layers to solve the problems of falling off and fire prevention, and achieve the same life of insulation and structure. However, both the infill wall and the outer protective layer of the shear wall are made of self-compacting concrete or fine stone concrete with high bulk density.

[0006] In summary, the existing shear walls and filling walls use anchoring to connect the insulation layer, protective layer and structural layer, but the connection effect of the insulation layer, protective layer and structural layer is still poor. After long-term use, the insulation layer and protective layer will fall off, resulting in poor fire protection performance.

[0007] Therefore, the art needs a new lightweight fireproof thermal insulation composite board to solve the above problems. Utility Model Content

[0013] A pad is arranged on the thermal insulation layer, the pad is connected to the steel mesh, and the pad is used to fix the steel mesh.

[0014] Preferably, the protective layer has a first perforated groove, the heat-insulating layer has a second perforated groove, and the first perforated groove is connected to the second perforated groove;

[0018] Preferably, the connecting member is any one of a steel truss or a connecting rod.

[0037] Example 1

[0038] Reference Figure 1~Figure 4 , which is the first embodiment of the utility model, proposes a lightweight fireproof thermal insulation composite panel, which is arranged outside the base wall, has an insulation layer 1 and a protective layer 2, and also includes: a steel mesh 4, which is arranged in the protective layer 2; a connecting piece 5, which is arranged in the insulation layer 1 and partially extends out of the side wall of the insulation layer 1 and is connected to the steel mesh 4, or the connecting piece 5 is sequentially passed through the protective layer 2 and the insulation layer 1 and connected to the steel mesh 4; a pad 3, which is arranged on the insulation layer 1, the pad 3 is clamped with the steel mesh 4, and the pad 3 is used to fix the steel mesh 4.

[0039] In the above scheme, the base wall is the building itself, and the insulation layer 1 and the protective layer 2 are both installed on the outer wall of the base wall. Specifically, the protective layer 2 is on the outermost side, and the insulation layer 1 is located between the protective layer 2 and the base wall. It should be noted that the insulation layer 1 and the protective layer 2 are both prefabricated parts.

[0040] During production, the insulation layer 1 is made of insulation material for construction. When producing the insulation layer 1, a perforated groove is reserved to facilitate the embedding of the connector 5 on the insulation layer 1. A portion of the connector 5 extends out of the insulation layer 1 to connect with the steel mesh 4. The pad 3 is used to fix the steel mesh 4 and limit the distance from the steel mesh 4 to the surface of the insulation layer 1 to determine the production thickness of the protective layer 2. Then the protective layer 2 is produced, and the connector 5 connects the steel mesh 4 and the insulation layer 1 and the protective layer 2 into a whole, effectively preventing the insulation layer 1 or the protective layer 2 from falling off. It should also be noted that the end of the connector 5 away from the protective layer 2 also needs to extend out of the insulation layer 1 to facilitate the subsequent connection of the connector 5 to the base wall, thereby improving the overall strength of the wall panel, improving the fire protection effect, and achieving the same lifespan of the insulation structure as the wall.

[0041] Furthermore, there are a plurality of pads 3, which are arranged in an array on the thermal insulation layer 1, and the pads 3 have a clamping groove 301, and the steel mesh 4 is clamped with the clamping groove 301. Furthermore, the steel mesh 4 has a cross-intersection portion 403, and the clamping groove 301 is a cross-intersection groove. The pads 3 are located at the cross-intersection portion 403, and the pads 3 are clamped with the cross-intersection portion 403 through the clamping groove 301.

[0042] In the above scheme, the steel mesh 4 includes a plurality of horizontal bars 401 arranged at intervals and a plurality of vertical bars 402 arranged at intervals. The position where each horizontal bar 401 and each vertical bar 402 cross-overlaps is a cross-intersection 403. The slot 301 on the pad 3 is snapped at the position of the cross-intersection 403, which can not only improve the connection strength of the steel mesh 4, but also improve the fixing strength of the pad 3 and the steel mesh 4.

[0043] It should be noted that the slot 301 of the pad 3 is a cross slot. In order to adapt to the overlapping method of the horizontal bar 401 and the vertical bar 402, the slot 301 is set as two slots of different depths, one deep and one shallow. Since the vertical bar 402 and the horizontal bar 401 are both round bars, the bottom of the slot 301 is also a semicircular groove, which further improves the connection strength between the pad 3 and the steel mesh frame, and effectively prevents the steel mesh 4 from loosening and causing the insulation layer 1 or the protective layer 2 to fall off.

[0044] Furthermore, the connecting member 5 is a steel truss, which is in any one of a U-shape, a Z-shape, a V-shape or a trapezoidal shape.

[0045] The steel truss is arranged in the insulation layer 1. When the insulation layer 1 is prefabricated, the steel truss is arranged at intervals in the insulation layer 1. One end of the steel truss extends out of one side of the insulation layer 1 for connection with the base wall, and the other end extends out of the other side of the insulation layer 1. This part is located in the protective layer 2 and is used to connect with the steel mesh 4.

[0046] In the above scheme, the steel truss can enhance the connection strength between the steel mesh 4 and the insulation layer 1, thereby improving the connection strength between the protective layer 2 and the insulation layer 1, and can also improve the connection strength between the protective layer 2, the insulation layer 1 and the base wall.

[0047] Furthermore, a groove 6 is provided between the side wall of the protective layer 2 and the side wall of the thermal insulation layer 1. The groove 6 can prevent the generation of a heat-through seam, and the thermal insulation layer 1 and the protective layer 2 are convenient to produce.

[0048] Furthermore, the material of the protective layer 2 is lightweight concrete. The protective layer 2 adopts lightweight concrete, which solves the problem of the built-in cast-in-place concrete system causing the protective layer 2 to be too heavy, thereby improving the safety of the system; at the same time, the integrated form of the thermal insulation structure is retained, the fireproof performance is excellent, and the insulation structure has the same life. The protective layer 2 adopts lightweight concrete with a thermal conductivity of ≤0.2 (W / m*K). Under the same design insulation requirements, the thickness of the insulation layer 1 is thinner. The original protective layer 2 is self-compacting concrete or fine stone concrete with a thermal conductivity of 1.74 (W / m*K). At the same time, the thermal bridge problem of the built-in insulation system connector 5 and the thermal bridge problem of the cantilevered components (eaves, awnings, etc.) are solved.

[0049] Example 2

[0050] Reference Figure 5 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0051] Compared with Embodiment 1, further, the connecting member 5 is a connecting rod.

[0052] Furthermore, the protective layer 2 has a first perforated groove 201, and the insulation layer 1 has a second perforated groove 101, and the first perforated groove 201 is connected to the second perforated groove 101; the connecting member 5 is arranged in the first perforated groove 201 and the second perforated groove 101, one end of the connecting member 5 is connected to the steel mesh 4, and the other end is connected to the base wall.

[0053] In the above scheme, further, the connecting rod is an L-shaped steel bar, specifically a point-connected L-shaped steel bar connection. The structure uses L-shaped steel bars for connection. When prefabricating the protective layer 2, a perforated groove of the L-shaped connector 5 is reserved to facilitate the installation of the L-shaped steel bar in the later construction and connect it with the steel mesh 4.

[0054] In the above scheme, the first perforated groove 201 and the second perforated groove 101 are through grooves. When the thermal insulation layer 1 and the protective layer 2 are prefabricated, the first perforated groove 201 and the second perforated groove 101 need to be reserved to facilitate the installation of the connector 5. It should be noted that when the protective layer 2 and the thermal insulation layer 1 are prefabricated, the connector 5 can be installed in the first perforated groove 201 and the second perforated groove 101, or the connector 5 can be installed in the first perforated groove 201 and the second perforated groove 101 after the thermal insulation layer 1 and the protective layer 2 are installed on site, which improves the flexibility of the installation of the connector 5. Moreover, after the connector 5 is installed, the connector 5 is completely located inside the protective layer 2 and the thermal insulation layer 1, which solves the thermal bridge problem of the connector 5 of the built-in thermal insulation system and the thermal bridge problem of the external cantilever component.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
