Description

Technical Field

[0001] The present invention relates to the technical field of prefabricated buildings, and in particular to an ultra-low energy consumption building energy-saving enclosure wall with independent double compartments and a manufacturing method thereof. Background Art

[0002] The Energy Conservation Law, which came into effect on January 1, 2025, includes building energy conservation as a national law. The 2024 edition of the Green Building Evaluation Standards has transformed green building from an optional requirement to a mandatory one. With the implementation of the "dual carbon" goals, near-zero energy consumption (75% energy savings) has been incorporated into local mandatory standards in temperate southern regions, and ultra-low energy consumption (85% energy savings) has been incorporated into cold northern regions. The Ministry of Housing and Urban-Rural Development's "Residential Project Standard," a construction industry standard, advocates for "safety," "comfort," "greenness," and "intelligence," while JG / T578, "Technical Requirements for Wall Panels for Prefabricated Buildings," raises the combustion performance of wall materials from the previously flame-retardant B1 grade to the current non-combustible A grade. The national standard for lightweight wall compressive strength (3.5 MPa) has made traditional wall materials, with lower standards, unable to meet the stringent requirements of the non-combustible A grade fire protection and ultra-low energy building energy conservation standards (K values ​​within 0.15 for thermal heat transfer after disassembly). Low-strength walls are one of the important reasons why the current retaining wall structure cannot have the same lifespan as the main structure. These low-strength walls not only waste a lot of precious resources, but also cause a large amount of construction waste to cause secondary pollution to the environment, thus giving rise to the demand for strengthening the transformation of existing building energy-saving retaining walls. Summary of the Invention

[0003] In response to the shortcomings of the existing technology, the present invention provides an ultra-low energy consumption building energy-saving enclosure wall with independent double compartments and a manufacturing method thereof. The wall has high strength, good thermal insulation and energy-saving performance, is not easy to crack and has a long service life, and can meet the existing building energy consumption and energy-saving standards.

[0004] To achieve the above-mentioned purpose, the technical solution provided by the present invention is: an ultra-low energy consumption building energy-saving enclosure wall with independent double compartments, comprising a wall frame, an insulation core and a leaf wall, and also comprising a Class A fireproof insulation board, the wall frame comprising two leaf wall non-removal formworks and a main keel and a secondary keel respectively fixed vertically on the inner side surfaces of the two leaf wall non-removal formworks, the leaf wall being attached to the outer side of the leaf wall non-removal formwork; the main and secondary keels are groove-shaped keels and are spaced apart in the width direction of the wall, the secondary keel is close to the inner side of the room and its width is less than the width of the main keel, the inner sides of each secondary keel are connected by keel tie pieces, the Class A fireproof insulation board is located between the main and secondary keels and is covered and fixed on the main keel; the insulation core is a non-combustible Class A insulation material, the insulation core is filled in the two compartments separated by the two leaf wall non-removal formworks and the Class A fireproof insulation board, and the insulation core is filled in the gap between the Class A fireproof insulation board and the secondary keel to form a thermal break layer.

[0005] The wall frame of the present invention creatively proposes independent main keels and secondary keels, and an independent thermal insulation double-compartment structure. The main keel and the secondary keel are not connected, and are respectively close to the outer leaf wall and the inner leaf wall. A gap is left between the main keel and the secondary keel, and this gap is filled with non-combustible Class A thermal insulation material to form a thermal break layer. It not only has excellent thermal insulation function, but also the main keel and the secondary keel are independently subjected to force without interfering with each other. Each independently transmits the force to the main structure of the building, realizing load transmission in different paths, forming a double curtain wall structure, avoiding mutual interference of the stresses of the inner and outer leaf walls, solving the cracking problem of traditional sandwich walls, and improving the life of the wall panels. Furthermore, the leaf wall's non-removable formwork is separated by Class A fireproof insulation panels, forming two insulated compartments. Heat must pass through these two compartments to be transferred. The Class A fireproof insulation panels work together with the non-combustible Class A insulation materials in the two compartments to form a composite insulated double-compartment structure. Experimental testing has proven that this can achieve a wall thermal transfer K value of ≤0.15, and the wall thickness is reduced by over 100mm compared to traditional rock wool insulation structures. Furthermore, the double-keel, double-leaf wall non-removable formwork structure not only creates a double curtain wall structure with independent force transmission paths, making the wall less prone to cracking, but also strengthens the wall skeleton, further increasing the wall's structural strength. The double-leaf wall non-removable formwork also serves as a non-removable formwork for the leaf wall attachment.

[0006] In order to further improve the strength of the wall panel skeleton, the leaf wall non-disassembly formwork includes a non-disassembly steel formwork, a steel mesh and a truss support component. Multiple truss support components connect the non-disassembly steel formwork and the steel mesh into a sandwich structure. The non-disassembly steel formwork is connected to the main keel or the secondary keel, and the two side edges of the non-disassembly steel formwork are connected to the non-disassembly steel formwork or the main structural column of the adjacent wall.

[0007] The leaf wall non-disassembly formwork is a three-dimensional double-layer structure. The bottom layer is the non-disassembly steel formwork, and the upper layer is the steel mesh. The two are supported and connected by multiple truss support members to form a three-dimensional structure. This three-dimensional structure of non-disassembly steel formwork has a mezzanine space and a supporting skeleton. Its effects are: 1. It has high strength and rigidity, and has thermal insulation and sound insulation functions; 2. There is a concrete protective layer between the steel mesh and the non-disassembly steel formwork, and the steel mesh also serves as the wall reinforcement and anti-cracking net; 3. At the same time, it serves as a leaf wall formwork that does not require support or disassembly, ensuring the thickness and strength of the wall leaf wall.

[0008] Furthermore, if you want to further reduce the wall thickness, or if the wall thermal transfer K value cannot meet the condition of ≤0.15 due to comprehensive reasons such as materials, you can further set an A1 grade thermal insulation coating layer on the surface of the dismantling-free steel formwork connecting the dismantling-free steel formwork and the main and secondary keels to further enhance the thermal insulation effect of the thermal insulation bridge.

[0009] Furthermore, as a more optimal solution, the upper and lower ends of the main keel are respectively connected to the main structural beam or plate on the outdoor side, and the upper and lower ends of the secondary keel are respectively connected to the main structural beam or plate on the indoor side.

[0010] Furthermore, in order to achieve better thermal insulation effect, the Class A fireproof insulation board is an inorganic Class A1 fireproof insulation board, and the inner side surface of the secondary keel and the Class A fireproof insulation board are spaced at least 30 mm apart.

[0011] To further enhance the strength and thermal insulation of the main keels, adjacent main keels are connected by horizontal keel anchors located near the inner edges of the main keels. The insulation core is a non-combustible, inorganic, Grade A1 rock wool board. The Grade A fireproof insulation board also serves as the horizontal anchor for the main keels. If the strength is insufficient, the keel anchors are connected to the main keels for reinforcement.

[0012] Furthermore, in order to realize the flexible connection of the main and auxiliary purlins to the main structure of the building, the upper and lower ends of the main purlin and the auxiliary purlin are respectively assembled and connected to the main structure beams or plates through right-angle connectors.

[0013] Furthermore, the side of the right-angle connector that connects to the main and secondary purlins is provided with a strip hole, which is parallel to the length of the main and secondary purlins. The strip hole facilitates installation with screws and allows slight displacement and expansion when the wall is subjected to high wind loads or thermal expansion and contraction, preventing cracking of the wall.

[0014] The present invention also provides a method for manufacturing an ultra-low energy consumption building energy-saving enclosure wall with independent double warehouses, which is used to manufacture the energy-saving enclosure wall, including the following steps: (1) fixing a plurality of the truss support members on the non-disassembly steel formwork by welding or riveting according to the designed position, and then placing the steel mesh on the truss support member and welding the two together, thereby making a leaf wall non-disassembly formwork for standby use; (2) assembling and connecting the upper and lower ends of the main keel with the main structure beam or plate through right-angle connectors, fixing them with screws, and then installing the A-class fireproof insulation board on the side of the main keel facing the interior, thereby connecting the adjacent main keels; (3) filling the insulation core between the adjacent main keels and the A-class fireproof insulation board, and connecting the leaf wall of the outer leaf wall The non-disassembly formwork is installed and fixed to the main keel; (4) The upper and lower ends of the secondary keel are respectively connected to the main structural beam or plate through right-angle connectors and fixed by screws. The inner side of the secondary keel and the Class A fireproof insulation board are spaced at least 30 mm apart; (5) The inner side of the secondary keel is connected by a keel tie piece, and the insulation core is filled and inserted between the Class A fireproof insulation board and the keel tie piece, as well as between two adjacent secondary keels, and the non-disassembly formwork of the inner leaf wall is installed and fixed to the secondary keel; (6) After the non-disassembly formwork of the inner and outer leaf walls is inspected and corrected, the leaf wall material is sprayed and the leaf wall water-hardening material is constructed so that the leaf wall concrete wraps the steel mesh of the leaf wall non-disassembly formwork, and the inner and outer leaf walls are formed after leveling and compaction.

[0015] Through the above manufacturing method, an ultra-low energy consumption building energy-saving enclosure wall with independent double compartments is obtained, which solves the technical problems of high strength, good thermal insulation and energy-saving performance, and the wall is not easy to crack and has a long service life, so as to meet the existing building energy consumption and energy-saving standards.

[0016] Furthermore, in order to achieve better structural strength and energy-saving effects, meet the local building energy-saving standards and requirements of specific wall panels such as pipeline boxes, in step (2), the inner sides of adjacent main keels are first connected with keel tie pieces, and then the Class A fireproof insulation board is installed; in steps (3) and (5), before installing the leaf wall non-removal formwork, the surface of the non-removal steel formwork connected to the main and secondary keels is first sprayed with an A1 class insulation coating layer; in step (6), according to the design, the pipes, wires, and boxes are pre-buried before the leaf wall water-hardening material construction is carried out.

[0017] The beneficial effects of the present invention are: the thermal heat transfer K value of the enclosing wall is low, it has excellent thermal insulation and energy-saving performance, and can meet the requirements of existing building energy consumption and energy-saving standards; the wall skeleton is high in strength, and the inner and outer leaf walls independently transmit force to the main structure of the building, forming a double curtain wall structure with independent force transmission paths, and the wall is not easy to crack and has a long service life.

[0025] The present invention will be described in further detail below with reference to the accompanying drawings. DETAILED DESCRIPTION

[0026] In the following example description, the direction "inside" refers to the inner direction of the wall, the direction "outside" refers to the outer direction of the wall, the "outer leaf wall" is close to the outdoor side, and the "inner leaf wall" is close to the indoor side. Figure 1-Figure 4As shown, an ultra-low energy consumption building energy-saving enclosure wall with independent double compartments includes a wall frame, an insulation core 7, a Class A fireproof insulation board 4 and a leaf wall. The wall frame includes two leaf wall non-removal formworks 3 and a main keel 1 and a secondary keel 2. A plurality of parallel main keels 1 and secondary keels 2 are respectively vertically fixed on the inner sides of the two leaf wall non-removal formworks 3, and the leaf wall is attached to the outer side of the leaf wall non-removal formworks 3; the main and secondary keels 1 and 2 are trough-shaped keels with two side edges, and the main keel 1 and the secondary keel 2 are spaced in the width direction of the wall. The secondary keel 2 is close to the inner side of the room and its width is smaller than the width of the main keel 1. This width refers to the width of the bottom of the trough of the trough-shaped keel. The inner sides of each secondary keel 2 are connected by a horizontal keel tie piece 9. Since the outer sides of each main and secondary keel 1 and 2 are fixed with a leaf wall non-removal formwork 3, it is equivalent to that the outer sides of each main and secondary keel 1 and 2 have been tied and connected through the leaf wall non-removal formwork 3. The Class A fireproof insulation board 4 is an inorganic Class A1 fireproof insulation board and is located between the main and secondary purlins 1 and 2. The Class A fireproof insulation board 4 covers and is fixed to the main purlin 1. The Class A fireproof insulation board 4 separates the two leaf wall non-removable formwork 3 into two insulating and heat-preserving compartments. The Class A fireproof insulation board 4 also serves as a horizontal force anchor on the inner side of the main purlin 1. In this embodiment, to enhance the strength of the main purlin 1, adjacent main purlins 1 are also connected by horizontal purlin anchors 9, which are located near the inner side of the main purlin 1. There is a minimum spacing of 30 mm between the inner side of the secondary purlin 2 and the Class A fireproof insulation board 4, and in this embodiment, the spacing is 40-50 mm.

[0027] To achieve better insulation, the insulation core 7 in this embodiment is a non-combustible, inorganic, Class A1 rock wool board. Rock wool boards are commercially available in a variety of thicknesses. The thickness of the rock wool board is roughly equal to the width of the primary and secondary purlins 1 and 2, as well as the distance between the inner side of the secondary purlin 2 and the Class A fireproof insulation board 4, to facilitate filling. The insulation core 7 is filled into the two compartments separated by the two leaf wall retaining formwork 3 and the Class A fireproof insulation board 4. The insulation core 7 forms a thermal bridge between the Class A fireproof insulation board 4 and the secondary purlin 2. The wall skeleton of the present invention creatively proposes an independent main keel 1 and secondary keel 2, and an independent thermal insulation double-compartment structure. The main keel 1 and the secondary keel 2 are not connected, and are respectively close to the outer leaf wall 5 and the inner leaf wall 6. A gap is left between the main keel 1 and the secondary keel 2, and this gap is filled with non-combustible Class A thermal insulation material to form a thermal break layer. It not only has excellent thermal insulation function, but also the main keel 1 and the secondary keel 2 are independently subjected to force without interfering with each other. Each independently transmits the force to the main structure of the building, realizes load transmission in different paths, forms a double curtain wall structure, avoids mutual interference of stress between the inner and outer leaf walls 6 and 5, solves the cracking problem of traditional sandwich walls, and improves the life of wall panels. Furthermore, the leaf wall's non-removable formwork 3 is separated by Class A fireproof insulation panels 4 to form two insulated compartments. Heat must pass through these two compartments to be transferred. The Class A fireproof insulation panels 4 work together with the non-combustible Class A insulation materials in the two compartments to form a composite insulated dual-compartment structure. Experimental testing has proven that this can achieve a wall thermal transfer K value of ≤0.15, and the wall thickness is reduced by over 100mm compared to traditional rock wool insulation structures. Furthermore, the double-keel, double-leaf wall non-removable formwork structure not only forms a double curtain wall structure with independent force transmission paths, making it less prone to cracking, but also strengthens the wall skeleton, further increasing the wall's structural strength. The double-leaf wall non-removable formwork also serves as a non-removable formwork for leaf wall attachment.

[0028] like Figure 2 、 Figure 3 As shown, the upper and lower ends of the main keel 1 are respectively connected to the main structural beam or plate 10 on the outdoor side, and the upper and lower ends of the auxiliary keel 2 are respectively connected to the main structural beam or plate 10 on the indoor side. In order to realize the flexible connection between the main and auxiliary keels 1 and 2, the upper and lower ends of the main keel 1 and auxiliary keel 2 are respectively assembled and connected to the main structural beam or plate 10 through right-angle connectors 8. Figure 2 The side of the right-angle connector 8 that connects to the main and secondary purlins 1 and 2 is provided with a strip hole 81, which is parallel to the length of the main and secondary purlins 1 and 2. The strip hole 81 facilitates installation with screws and allows slight displacement and expansion when the wall is subjected to high wind loads or thermal expansion and contraction, preventing cracking in the wall.

[0029] like Figure 5 and Figure 6As shown, in order to further improve the strength of the wall panel skeleton, the leaf wall non-disassembly formwork 3 includes a non-disassembly steel formwork 31, a steel mesh 32 and a truss support member 33. Multiple truss support members 33 connect the non-disassembly steel formwork 31 and the steel mesh 32 into a sandwich structure. The non-disassembly steel formwork 31 is connected to the main keel 1 or the secondary keel 2. The two sides of the non-disassembly steel formwork 31 are connected to the non-disassembly steel formwork 31 or the main structure column of the adjacent wall. The truss support member 33 can be as follows Figure 4 The midpoint is fixedly distributed on the non-dismantling steel template 31, or it can be Figure 5 As shown, the truss support member 33 is formed from a single steel bar into multiple trapezoidal protrusions. The bottom of the groove between adjacent trapezoidal protrusions is butt-welded to the reinforcement bars protruding from the non-dismantling steel formwork 31, and the top of the trapezoidal protrusions is welded to the steel mesh 32. Using a single steel bar to form multiple support points simplifies the manufacturing process, is easy to implement, reduces costs, and improves processability. The formed strip truss support members 33 can be roughly evenly distributed on the non-dismantling steel formwork 31.

[0030] The leaf wall non-disassembly formwork 3 is a three-dimensional double-layer structure, the inner layer is the non-disassembly steel formwork 31, and the outer layer is the steel mesh 32. The two are supported and connected by multiple truss support members 33 to form a three-dimensional structure. The non-disassembly steel formwork 31 of this three-dimensional structure has a mezzanine space and a supporting skeleton, and its effects are: 1. It has high strength and rigidity, and has thermal insulation and sound insulation functions; 2. There is a concrete protective layer between the steel mesh 32 and the non-disassembly steel formwork 31, and the steel mesh 32 also serves as the wall reinforcement and anti-cracking net; 3. At the same time, it serves as a leaf wall formwork that does not require support or disassembly, ensuring the thickness and strength of the wall leaf wall.

[0031] The main and secondary purlins 1 and 2 are flexibly connected to the main structure. The main and secondary purlins 1 and 2 respectively transmit the stress borne by the outer and inner leaf walls 5 and 6 to the main structure through the main and secondary purlins 1 and 2, forming a combination of "external curtain wall structure" and "inner curtain wall structure". An insulating bridge layer is formed between the double curtain walls. This "ultra-low energy consumption building energy-saving enclosure wall" with a double curtain wall structure is in line with the "four new technologies, new processes, new materials, and new equipment" of construction and the development direction of industrialization of prefabricated buildings.

[0032] The present invention also provides a method for manufacturing an ultra-low energy consumption building energy-saving enclosure wall with independent double warehouses, which is used to manufacture the energy-saving enclosure wall of Example 1, comprising the following steps: (1) fixing a plurality of the truss support members 33 on the non-disassembly steel formwork 31 by welding or riveting according to the designed position, and then placing the steel mesh 32 on the truss support member 33 and welding the two together to form a leaf wall non-disassembly formwork 3 for standby use; (2) assembling and connecting the upper and lower ends of the main keel 1 with the main structure beam or plate 10 through right-angle connectors 8 respectively, fixing them with screws, connecting the inner sides of adjacent main keels 1 with keel tie pieces 9, and then installing the A-class fireproof insulation board 4 on the side of the main keel 1 facing the room, thereby tying and connecting the adjacent main keels 1; (3) filling the insulation core 7 between the adjacent main keels 1 and the A-class fireproof insulation board 4, The leaf wall non-removal formwork 3 of the outer leaf wall 5 is installed and fixed to the main keel 1; (4) the upper and lower ends of the secondary keel 2 are respectively assembled and connected to the main structure beam or plate 10 through the right-angle connector 8, and fixed by screws, and the inner side edge of the secondary keel 2 and the Class A fireproof insulation board 4 are at least spaced at a distance of not less than 30 mm; (5) the inner side edge of the secondary keel 2 is connected by the keel tie piece 9, and the insulation core 7 is filled and inserted between the Class A fireproof insulation board 4 and the keel tie piece 9, and between two adjacent secondary keels 2, and the leaf wall non-removal formwork 3 of the inner leaf wall 6 is installed and fixed to the secondary keel 2; (6) after the leaf wall non-removal formwork 3 of the inner and outer leaf walls 5 is inspected and corrected, the leaf wall material is sprayed, and the leaf wall water hardening material is constructed so that the leaf wall concrete wraps the steel mesh 32 covering the leaf wall non-removal formwork 3, and after leveling and compacting, the inner leaf wall 6 and the outer leaf wall 5 are formed. In this embodiment, the leaf wall uses solid waste recycled concrete with a compressive strength of ≥10Mpa to wrap the steel mesh. When the leaf wall hardening material is absorbing sweat, cement coarse sand mortar is used to add mortar and level it, and then compact and smooth it. After the water-hardening materials of the inner and outer leaf walls harden, water them and maintain them reasonably for several days.

[0033] The above-mentioned manufacturing method achieves an ultra-low-energy energy-saving building enclosure wall with independent dual compartments. This solves the technical challenges of achieving high strength, excellent thermal insulation and energy-saving properties, and a long lifespan that resists cracking, thus meeting existing building energy conservation standards. Tests have shown that the thermal conductivity K value of a wall with a total thickness of approximately 350mm can be controlled within 0.15.

[0034] Example 2: Figure 7As shown, in this embodiment, the structure of each component and the connection relationship between them are basically the same as those in Example 1. The difference is that an A1-class thermal insulation coating layer is provided on the surface of the dismantling-free steel formwork 31 connected to the main and secondary keels 1 and 2 to further enhance the thermal insulation effect. The bottom of the main and secondary keels 1 and 2 in this embodiment is wavy, which further strengthens the keel. In this embodiment, the main keel bin near the outer leaf wall 5 is filled with two stacked non-combustible inorganic A1-class rock wool boards according to the keel width, and the secondary keel bin near the inner leaf wall 6 is also filled with two non-combustible inorganic A1-class rock wool boards, one of which is located between the inner side of the secondary keel 2 and the A-class fireproof insulation board 4 to form a thermal insulation layer, and the other is located in the secondary keel 2 and is the same width as the secondary keel 2.

[0035] The manufacturing method of Example 2 is based on Example 1, except that in steps (3) and (5), before installing the leaf wall non-removal formwork 3, the surface of the non-removal steel formwork 31 connected to the main and secondary keels 1 and 2 is sprayed with an A1-class thermal insulation coating to form an A1-class thermal insulation coating layer. In addition, depending on the wall design, in step (6), pipes, wires, and boxes can be pre-buried before the leaf wall water-hardening material is installed.

[0036] The retaining wall produced by the present invention has a low thermal heat transfer K value, excellent thermal insulation and energy-saving performance, and can meet the requirements of existing building energy consumption and energy-saving standards; the wall skeleton has high strength, and the inner and outer leaf walls independently transmit force to the main structure of the building, forming a double curtain wall structure with independent force transmission paths. The wall is not easy to crack and has a long service life.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
