Referring to fig. 1 and 3, the fabricated composite wall according to the present embodiment includes an interior surface layer 1, a structural frame (not shown), a support member 2, an insulation layer 3, an exterior surface layer 4, a cold and hot bridge blocking layer 5, a waterproof material layer (not shown), and a decorative coating (not shown). The structural framework is internally provided with an installation cavity, namely, the installation cavity is formed into a frame-shaped structure and distributed around the composite wall, the supporting members 2 are installed in the installation cavity of the structural framework and are fixedly connected with the inner wall of the structural framework, for example, welded or connected through fasteners such as screws, rivets and the like, and the structural framework and the supporting members 2 jointly form a stress member. The supporting member 2 is not a flat plate, as shown in fig. 3, a plurality of recesses 21 and protrusions 22 are formed on the surface, and specifically, one protrusion 22 is formed between two adjacent recesses 21, the depth of the recess 21 and the height of the protrusion 22 should not exceed the outer side of the installation cavity of the structural frame, that is, the recess or the bottom of the recess 21 is preferably even with the surface of the structural frame, or may be completely located in the installation cavity. The convex surface of the projection 22 is preferably flat with the surface of the structural frame and may be located entirely within the mounting cavity. That is, the male part 22 and the female part 21 of the support member are both located within the mounting cavity and do not extend outside the mounting cavity. The heat insulating layer 3 is filled in the concave portion 21, and may be fixed by a fastening member or may be fixed by adhesion such as an adhesive. The interior facing layer 1 and the exterior facing layer 4 are oppositely disposed at intervals on both sides of the fixing frame, i.e., the upper and lower sides as shown in fig. 1. The waterproof material layer is tightly attached between the heat preservation layer 3 and the outer facing layer 4, and water is prevented from permeating into the heat preservation layer 3 and the inner wall. The cold-hot bridge blocking layer is arranged between the finishing layer 4 and the structural frame and between the finishing layer 4 and the support element 2, in particular in a first filling space between the structural frame and the finishing layer and in a second filling space between the protrusions 22 of the support element 2 and the finishing layer 4, that is to say, the cold-hot bridge blocking layer is arranged outside the structural frame. The outer surfaces of the inner decorative surface layer 1 and the outer decorative surface layer 4 are respectively coated with decorative coatings, such as emulsion paint or stone paint, and specifically, the decorative coating of the inner decorative surface layer 1 is emulsion paint, and the decorative coating of the outer decorative surface layer 4 is stone paint. The distance between the outer surface of the interior finishing layer 1, i.e., the lower surface as shown in fig. 1, and the outer surface of the exterior finishing layer 4, i.e., the upper surface as shown in fig. 1, is the total thickness of the composite wall, and specifically, the total thickness of the composite wall is 150mm to 200 mm.
The interior surface layer 1 can be selected from conventional gypsum boards in the existing market, is tightly attached to the lower surface of the supporting member 2, specifically the supporting member 2 shown in fig. 1, and is directly attached to ensure the requirement of single-point hanging force required by interior decoration. Alternatively, a gap may be reserved between the lower surface of the supporting member 2 and the gypsum board, that is, the gypsum board is hung on the lower surface of the supporting member 2 by using conventional screws and the like. The size of the gap is not described in detail, as long as the total thickness of the composite wall is ensured to be 150-200 mm.
The support member 2 is a profiled steel sheet having a plurality of protrusions 22 and recesses 21, wherein the protrusions 22 include end ribs protruding upward toward the exterior finishing layer 4 as shown in fig. 3 at both ends and a middle rib protruding toward the exterior finishing layer 4 in the middle, and the recesses are located in the middle and are recessed downward toward the interior finishing layer as shown in fig. 1. Preferably, as shown in fig. 3, the support member 2 is formed with three recesses 21 depressed downward toward the interior finishing layer 1, i.e., as shown in fig. 1, and two protrusions 22 protruded upward toward the exterior finishing layer 4, i.e., as shown in fig. 1, in the middle thereof, one recess 21 is formed between two adjacent protrusions 22 or one protrusion 22 is formed between two adjacent recesses 21, and each recess 21 is filled with one insulating layer 3. That is, the convex portions 22 and the concave portions 21 are arranged alternately. Optionally, the concave surface of the concave portion 21, that is, the lower surface of the concave portion 21 shown in fig. 1 is flush with the lower cavity of the installation cavity or the lower side surface of the structural frame, or the convex bottom of the convex portion 22 is flush with the lower cavity of the installation cavity or the lower side surface of the structural frame, so that the interior finishing layer 1 and the supporting member 2 are tightly attached to each other, the total thickness of the wall body can be effectively reduced, the structural strength of the composite wall body is improved, and the single-point hanging force of the interior finishing layer during interior finishing is improved. The recess of the recess 21 is flush with the convex surface of the projection 22, i.e. the top end surface of the projection 22, and with the upper mouth of the mounting cavity or the upper side of the structural frame. Alternatively, the concave surfaces of the concave and convex portions 21 and 22 are not flat with the upper side of the mounting cavity, i.e. the concave surfaces of the concave and convex portions are both located below the upper opening of the mounting cavity, while the concave surfaces of the concave and convex portions 22 are flat with the lower opening of the mounting cavity. It is also possible that the recesses of the recesses 21 and the convex surfaces of the protrusions 22 are level with the upper mouth of the mounting cavity and the concave surfaces of the recesses and the convex bottoms of the protrusions 22 are not level with the lower mouth of the mounting cavity. Preferably, the concave of the concave portion 21 and the convex of the convex portion 22 are flush with the upper opening of the mounting cavity and the concave of the concave portion and the convex of the convex portion 22 are flush with the lower opening of the mounting cavity.
The projections 22 are formed in a tapered shape in a direction from the outer surface layer 4 toward the inner surface layer 1, that is, in a direction from top to bottom as shown in fig. 1. Preferably, the cross-section of the protrusion 22 is a closed triangle. As shown in fig. 3, the contact between the left side of any one of the convex portions 22 and the bottom of the left concave portion 21 and the contact between the right side of the other convex portion 22 and the bottom of the right concave portion 21 are closely adhered to each other, so that the convex portion has a closed structure. The closed structure can improve the overall structural strength of the supporting member 2 and improve the bearing capacity of the stressed member. Alternatively, the cross-sectional shape of the convex portion 22 may be other shapes such as circular arc, square, and the like.
The insulating layer 3 is preferably made of conventional ALC board (short for Autoclaved Lightweight Concrete) on the market, and has a thickness slightly larger than the recess 21, that is, the insulating layer 3 partially extends out of the recess 21. Specifically, as shown in fig. 1, the notch extending from the insulating layer 3 to the recess 21 forms an outer extension, and the outer extension is closely attached to the outer facing layer 4. That is, the total thickness of the composite wallboard is actually the sum of the thicknesses of the inner facing layer 1, the supporting member 2, the ALC board and the outer facing layer 4, the integrity of the wallboard is improved, and meanwhile, the total thickness of the wallboard is effectively reduced. It should be noted here that the thickness of the support member 2 refers to the thickness of the concave bottom of the concave portion 21 or the thickness of the convex surface of the convex portion 22, and does not refer to the thickness from the concave bottom of the concave portion 21 to the convex surface of the convex portion 22. Since the convex surface of the convex portion 22 and the concave portion of the concave portion 21 are located on the same horizontal plane, a space is formed between the convex surface of the convex portion 22 and the upper side surface of the structural frame and the exterior facing layer 4, and a cold and heat bridge blocking layer is filled in the space to prevent the cold and heat bridge effect, that is, the cold and heat bridge blocking layer is located on the outer side of the structural frame. Optionally, the thickness that layer was blocked to cold and hot bridge is unanimous with the thickness of extension portion, that is to say that cold and hot bridge blocks and closely laminates between layer and the exterior finish coat 4, when having improved the joint firmness, has also reduced the whole thickness of baffle. Specifically, the outer facing layer 4 is the thermal insulation mortar coated on the outer surface of the ALC board, and because the thermal insulation layer 3 extends to the outside of the structural frame, when the thermal insulation mortar is coated, part of the thermal insulation mortar can be filled in the gap formed between the convex surface of the structural frame and the convex part 22 and the outer facing layer 4 to form a cold and hot bridge blocking layer, thereby effectively preventing the cold and hot bridge effect of the gap between the outer facing layer 4 and the structural frame and between the outer facing layer 4 and the supporting member 2.
It should be noted that, a plurality of insulating layers 3 of the present embodiment are arranged at intervals, and each insulating layer 3 is filled in one concave portion 21 of the supporting member 2, that is, there is no connection between two adjacent insulating layers 3, so that the insulating layers 3 are convenient to install, and the problem of labor waste in installing large panels is avoided.
In order to ensure the waterproof performance of the composite wall, a waterproof material layer is further added on the outer surface of the heat-insulating layer 3, and is selected from the conventional waterproof interface agents in the existing market, and the detailed description and limitation are omitted. And a waterproof interface agent is arranged between the heat-insulating layer 3 and the outer decorative surface layer 4 to improve the waterproofness of the composite wall body, so that the phenomenon that water permeates into the heat-insulating layer 3 to damage the heat-insulating layer 3 or permeates into an inner wall to influence the use of the whole wall body is avoided. At this time, the total thickness of the wallboard is the sum of the thicknesses of the interior facing layer 1+ the support member 2+ the ALC board + the waterproof interface agent + the exterior facing layer 4. Similarly, the thickness of the support member 2 herein refers to the thickness of the concave bottom of the concave portion 21 or the thickness of the convex surface of the convex portion 22, and does not refer to the thickness from the concave bottom of the concave portion 21 to the convex surface of the convex portion 22.
It should be noted that, the composite wall body of the embodiment is used in areas warm in summer and warm in winter, the building wall body of the existing areas warm in summer and warm in winter generally has no heat insulation layer, most of the building wall bodies adopt single concrete or common building block materials with poor heat insulation performance, the proportion of the building energy consumption generated by wall body heat transfer to the total building energy consumption is large, and the requirements of related energy-saving indexes and regulations cannot be met. The ALC board is filled in the concave part of the support member 2, so that the heat preservation and heat insulation performance of the wallboard is improved, the heat preservation and heat insulation requirements of the building outer wall in hot summer and warm winter can be met, and the thermal performance of the wall body reaches the related energy-saving index. The ALC plate, the support member 2 and the structural framework jointly form a stressed member, and the integrity of the wall body is improved. The inner decorative surface layer 1 and the supporting member 2 act to improve the single-point hanging force of the inner wall surface. In addition, ALC board is filled in the recess 21 of the bracing member 2, the bracing member 2 is located in the installation cavity of the structural frame, the thickness of the wallboard can be greatly reduced, energy conservation and structural integrity are ensured, meanwhile, the occupied space of the wallboard is reduced, the manufacturing cost is lower, and the manufacturing cost of the composite wallboard is about 250 yuan/m2. The cold and hot bridge blocking layer filled in the second filling space between the convex surface of the convex portion 22 and the exterior finish layer 4 and the first filling space between the structural frame and the exterior finish layer 4 is specifically thermal insulation mortar which is a low thermal conductivity material and can effectively block the acoustic bridge and the cold and hot bridge.
Example 2
Referring to fig. 2 and 3, the difference from the embodiment 1 is that the composite wall panel of the embodiment is used in cold regions, the cold regions are mainly northern regions of China, the climates are mainly temperate zone monsoon climate and temperate zone continental climate, the winter is cold and dry, and the time span is long. Correspondingly, the outer facing layer 4 is a calcium silicate plate hung outside the heat-insulating layer 3. The calcium silicate board is used as an external decorative material and has waterproof function. The heat insulating layer 3 filled in the recess 21 of the support member 2 is rock wool. The rock wool is used as a heat insulation layer, has good heat insulation performance and simultaneously gives consideration to excellent fireproof performance. Optionally, the thickness of the rock wool is 100mm, and correspondingly, the depth of the concave portion 21 is less than 100mm, that is, the thickness of the installation cavity is less than 100mm, which is not specifically described and limited in detail, for example, the total thickness of the composite wall body, that is, the total thickness of the interior facing layer 1+ the supporting member 2+ the rock wool + the waterproof breathable film + the exterior facing layer 4 is 150 mm. Similarly, the thickness of the support member 2 herein refers to the thickness of the concave bottom of the concave portion 21 or the thickness of the convex surface of the convex portion 22, and does not refer to the thickness from the concave bottom of the concave portion 21 to the convex surface of the convex portion 22.
Meanwhile, in northern areas, the requirements for moisture removal are high in summer heat and rainy days, and in the same rain and heat period. Correspondingly, the waterproof material layer between the heat-insulating layer 3 and the outer facing layer 4 is a waterproof breathable film. The waterproof performance is guaranteed, and meanwhile the air permeability and moisture removal performance of the wallboard is improved.
The cold and heat bridge blocking layers filled in the first filling space between the structural frame and the exterior surface layer 4 and the second filling space between the convex surface of the convex portion 22 and the exterior surface layer 4 are rubber pads. Otherwise, the remaining components were the same as the composite wall panel of example 1.
In the composite wallboard of the embodiment, the supporting member 2 is filled in the installation cavity of the structural frame, so that the supporting member 2 and the structural frame jointly form a stressed member, and the integrity of the wallboard is enhanced. The supporting member 2 and the interior surface layer 1 such as a gypsum board work together to ensure the requirement of single-point hanging force required in the indoor decoration. The rock wool also improves the fireproof performance of the wall body while ensuring the heat preservation and heat insulation performance of the wall body. The waterproof breathable film ensures the waterproof performance of the outer wall and simultaneously ensures the breathable and moisture-removing performance of the outer wall, and meets the requirements of building walls in cold and hot areas.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
