Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to an integrated heat-insulating wall with a steel mesh truss and a non-disassembly template. Background Art

[0002] With the development of energy-saving buildings, building industrialization, and the improvement of green prefabricated building standards, various regions have raised local building energy-saving indicators according to local climatic conditions. Building envelope systems are green building passive energy-saving technologies and products, accounting for about 13% of the total social carbon emissions. In particular, the JG / T578-2021 "Technical Requirements for Wall Panels for Prefabricated Buildings" construction industry product standard implemented on March 1, 2022, regards various types of "keel walls" as prefabricated building walls. Article 5.3.9 of the industry standard stipulates that the combustion performance of exterior walls shall be increased to non-combustible Class A, and the energy-saving standards for near-zero energy buildings in temperate areas of southern provinces and cities shall be increased to 75% energy saving, while the energy-saving standards for ultra-low energy buildings in cold areas of northern provinces and cities shall be increased to 85% energy saving. As local mandatory standards, the national "Prefabricated Building Evaluation Standard" stipulates that all non-masonry walls shall be used as components and parts of prefabricated building enclosure systems, and walls constructed of various blocks and masonry, including autoclaved aerated foam blocks, can no longer be used. However, traditional non-masonry walls are difficult to meet the current national and local mandatory standards, and cannot meet the design requirements of wall earthquake resistance, wind load resistance, wall surface density (bulk density), and overcoming wall cracking defects. Utility Model Content

[0003] In response to the shortcomings of the existing technology, the utility model provides an integrated insulation wall with a steel mesh truss and a non-dismantling formwork, which has high waterproof, heat-insulating, sound-insulating and fire-proof performance. No formwork needs to be supported or dismantled during the production process, and the existing building energy consumption and energy-saving standards can be achieved at a lower cost.

[0004] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is: an integrated insulation wall with a steel mesh truss and a non-disassembly formwork, comprising a wall frame, an insulation core and a leaf wall, wherein the wall frame comprises a wall frame and a wall non-disassembly formwork, and the wall non-disassembly formwork is located on both sides of the insulation core; the wall non-disassembly formwork comprises a non-disassembly steel formwork, a steel mesh and a truss support member, and a plurality of truss support members connect the non-disassembly steel formwork and the steel mesh into one, and the two side edges of the non-disassembly steel formwork are fixed to the wall frame; the insulation core is between the inwardly opposed non-disassembly steel formworks, and the insulation core is a non-combustible Class A insulation material.

[0005] The wall skeleton of the present utility model creatively proposes a non-disassembly formwork for the wall. The non-disassembly formwork for the wall is a three-dimensional double-layer structure. The bottom layer is a non-disassembly steel formwork, and the upper layer is a steel mesh. The two are supported and connected by multiple truss support members to form a three-dimensional structure. The two sides of the non-disassembly steel formwork are fixedly connected to the wall frame to form the wall skeleton. This three-dimensional non-disassembly steel formwork has a mezzanine space and a supporting skeleton, and its effects are: 1. It has high strength and rigidity, and has the functions of heat insulation, heat insulation and sound insulation; 2. It provides 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. It accurately fixes the wall insulation layer in the middle of the wall and serves as a leaf wall formwork to ensure the thickness and strength of the wall leaf wall; 4. It does not require formwork or demoulding, and its manufacturing cost is lower than that of traditional products and technologies under the same acceptance conditions.

[0006] An insulation core made of non-combustible Class A insulation material is installed within the skeleton cavity formed by the wall frame and the wall formwork on both sides. The insulation core can be a filler layer filled within the skeleton cavity. The thickness of the insulation core is designed based on the specific material selected and the requirements of local building energy-saving standards. By installing a three-dimensional, non-removal steel formwork composed of steel plates and steel mesh on both sides of the wall, the insulation core is made of non-combustible Class A insulation material. The resulting integrated wall panel has high waterproof, thermal, soundproof, and fireproof performance. No formwork is required during the production process, and existing building energy-saving standards are achieved at a low cost.

[0007] Furthermore, the insulation core is a filling layer, and a correction layer is provided between the filling layer and the wall-mounted formwork on one or both sides. The correction layer is a thermal and sound insulation coating layer or a thermal and sound insulation mat. To achieve better energy savings and meet local building energy-saving standards, in addition to adjusting the thickness of the insulation core, correction layers can also be added. This also facilitates mass production of insulation cores of the same thickness. By adding and adjusting the thermal and sound insulation correction layers, the existing energy-saving standards for near-zero energy buildings in temperate southern regions (75%) and ultra-low energy buildings in cold northern regions (85%) can be met.

[0008] Furthermore, as a preferred embodiment, the heat and sound insulation pad is made of aluminum foil or rock wool wrapped with aluminum foil.

[0009] Furthermore, in order to achieve better load-bearing effect and excellent strength, the truss support members are evenly distributed on the non-dismantling steel formwork, the truss support members are provided with a base for fixing to the non-dismantling steel formwork, and the top of the truss support members is welded to the steel mesh.

[0010] Furthermore, the truss support member is formed from a single steel bar into multiple trapezoidal protrusions. The groove bottoms between adjacent trapezoidal protrusions form the base. The groove bottoms are welded to the non-disassembly steel formwork, and the tops of the trapezoidal protrusions are welded to the steel mesh. This method of forming multiple support points from a single steel bar is simple to manufacture, easy to implement, low in cost, and highly manufacturable.

[0011] Furthermore, the non-dismantling steel formwork is provided with upwardly protruding reinforcement ribs, and the groove bottom is butt-welded to the reinforcement ribs. The reinforcement ribs can not only strengthen the non-dismantling steel formwork, but also serve as welding parts for butt welding with the truss support members.

[0012] Furthermore, as another embodiment, the truss support member is a strip of L-shaped right-angled plates, one right-angled surface of which serves as a base welded to the non-dismantling steel formwork; the other right-angled surface is welded to the steel mesh at its top, and a feed hole is provided on this right-angled surface. The truss support member is formed from thin steel plate and can be welded and arranged across the width of the non-dismantling steel formwork.

[0013] Furthermore, the non-dismantling steel formwork is provided with upwardly projecting reinforcement ribs, and the base spans and is welded to multiple reinforcement ribs. The reinforcement ribs can be arranged along the length of the non-dismantling steel formwork, with strip-shaped truss support members perpendicular to the reinforcement ribs. A single truss support member spans and is welded to multiple reinforcement ribs, with the intersection of the truss support member and the reinforcement ribs forming the welded portion. Furthermore, the reinforcement ribs can also strengthen the non-dismantling steel formwork.

[0014] Furthermore, in order to achieve better waterproofing, heat preservation, thermal insulation and sound insulation effects in a low-cost and waste-recycling manner, the thermal insulation core is at least one of rock wool, glass wool, perlite, vermiculite or recycled lightweight ceramsite; the leaf wall is lightweight concrete, which is coated on the outside of the steel mesh and fills the space between the steel mesh and the disassembly-free steel formwork.

[0015] Furthermore, as a preference, the length of the wall-free formwork is 1800-2600 mm, and the width is 500-700 mm.

[0026] like Figure 1-Figure 4As shown, a steel mesh truss integrated insulation wall with a non-disassembly formwork includes a wall frame, an insulation core 2, and a leaf wall 3. The wall frame includes a wall frame and a non-disassembly formwork 1, which is located on both sides of the insulation core 2. The non-disassembly formwork 1 includes a non-disassembly steel formwork 11, a steel mesh 12, and truss support members 13. Multiple truss support members 13 connect the non-disassembly steel formwork 11 and the steel mesh 12 into one. In this embodiment, the length of the non-disassembly wall formwork 1 is 2400-2500mm and the width is about 600mm. The steel mesh 12 is the same size as the non-disassembly wall formwork 1. The truss support members 13 are evenly distributed on the non-dismantling steel formwork 11. The height of the truss support members 13 is 18-20 mm. The truss support members 13 are provided with a base 131 for fixing to the non-dismantling steel formwork 11. The top of the truss support member 13 is welded to the steel mesh 12 by butt welding. The two sides of the non-dismantling steel formwork 11 are fixed to the wall frame. On both sides of the wall frame, the non-dismantling steel formwork 11, the steel mesh 12 and the truss support members 13 are fixed to form a wall non-dismantling formwork 1 that is connected into one body. The wall non-dismantling formwork 1 is a three-dimensional double-layer structure. The bottom layer is the non-dismantling steel formwork 11, and the upper layer is the steel mesh 12. The two layers are supported and connected by multiple truss support members 13 to form a three-dimensional structure. The two sides of the non-dismantling steel formwork 11 are fixed to the wall frame to form the wall skeleton. This three-dimensional structure of the non-disassembly steel formwork 11 has a mezzanine space and a supporting skeleton, high strength and rigidity, and has the functions of thermal insulation, heat insulation and sound insulation, so that there is a concrete protective layer between the steel mesh 12 and the non-disassembly steel formwork 11. The steel mesh 12 also serves as the wall reinforcement and anti-cracking net, accurately fixing the wall insulation layer in the middle position of the wall, and at the same time serving as the leaf wall 3 formwork, ensuring the thickness and strength of the wall leaf wall 3, and there is no need to support or dismantle the formwork. Under the same acceptance conditions, the manufacturing cost is lower than that of traditional products and technologies.

[0027] A skeleton cavity for accommodating the insulation core 2 is formed between the wall frame and the wall non-disassembly formwork 1 on both sides. The non-disassembly steel formwork 11 of the wall non-disassembly formwork 1 on both sides faces the inside of the wall and is opposite to each other. Between the non-disassembly steel formwork 11 is the insulation core 2, which is a non-combustible Class A insulation material. The insulation core 2 is at least one of rock wool, glass wool, perlite, vermiculite or recycled lightweight ceramsite. In this embodiment, rock wool is used for filling to form a filling layer. The thickness of the insulation core 2 is designed according to the specific selected material and the requirements of the local building energy-saving standards. By arranging a three-dimensional non-disassembly steel formwork 11 composed of steel plates and steel mesh 12 on both sides of the wall, the insulation core 2 is made of non-combustible Class A insulation material, and the integrated wall panel made of the non-disassembly steel formwork has high waterproof, heat-insulating, heat-insulating, sound-insulating and fire-proof performance. No formwork needs to be supported or disassembled during the production process, and the existing building energy-saving standards are achieved at a lower cost.

[0028] like Figure 3 、 Figure 4As shown, to achieve better load-bearing performance and excellent strength, the non-dismantling steel formwork 11 is provided with several upwardly projecting parallel reinforcing ribs. The truss support member 13 is formed from a single steel bar into multiple trapezoidal protrusions. The groove bottom between adjacent trapezoidal protrusions forms the base 131, which is butt-welded to the reinforcing ribs. The tops 132 of the trapezoidal protrusions are welded to the steel mesh 12. Using a single steel bar to form multiple support points is simple, easy to implement, low in cost, and highly manufacturable. The reinforcing ribs not only strengthen the non-dismantling steel formwork 11, but also serve as welds for butt-welding with the truss support members 13. In this embodiment, each steel bar forming the truss support member 13 is arranged parallel to the width of the non-dismantling steel formwork 11. After forming, each steel bar is the same length as the width of the non-dismantling steel formwork 11. Of course, the steel bars can also be staggered on the non-dismantling steel formwork 11, as long as the truss support members 13 are roughly evenly distributed on the non-dismantling steel formwork 11.

[0029] The wall's non-removable formwork 1 is covered with leaf walls 3, which are made of lightweight concrete. These walls wrap around the steel mesh 12 and fill the space between the mesh and the non-removable steel formwork 11. The lightweight concrete is made of quarry waste stone powder concrete, fine stone concrete, recycled lightweight ceramsite concrete, or recycled concrete from construction waste, with a compressive strength of no less than 10 Map. This achieves improved waterproofing, thermal insulation, heat insulation, and sound insulation at a low cost and by utilizing waste.

[0030] like Figures 5 to 7 As shown, the truss support member 13 can also be a strip L-shaped right-angle plate, wherein one right-angle surface is a base 131 that is abutted and welded to the non-dismantling steel formwork 11; and the top of the other right-angle surface 134 is connected to the steel mesh 12 (such as Figure 1 The right-angled surface 134 is welded together (as shown), and a circular feed hole 133 is provided on the right-angled surface 134. The feed hole 133 is used to pass lightweight concrete so that the lightweight concrete can pass through and fill quickly and evenly. The edges of the two right-angled surfaces are curled inward to strengthen the truss support member 13. Five parallel upwardly protruding reinforcing ribs 111 are provided on the non-dismantling steel formwork 11. The reinforcing ribs 111 are arranged in the length direction of the non-dismantling steel formwork 11, that is, parallel to the length direction of the non-dismantling steel formwork 11. The truss support member 13 is formed by thin steel plates and is welded and arranged in the width direction of the non-dismantling steel formwork 11, that is, parallel to the width direction of the non-dismantling steel formwork 11. The strip-shaped truss support member 13 is perpendicular to the reinforcing ribs 111. One truss support member 13 spans five reinforcing ribs 111 and is welded together. The intersection of the truss support member 13 and the reinforcing ribs 111 is the welding portion; in addition, the reinforcing ribs 111 can also strengthen the non-dismantling steel formwork 11.

[0031] The manufacturing method of the present invention comprises the following steps: (1) fixing a plurality of the truss support members 13 on the non-disassembly steel formwork 11 by welding or riveting according to the designed position, and then placing the steel mesh 12 on the truss support member 13 and welding the two together, thereby making a plurality of wall non-disassembly formworks 1 for standby use; (2) first installing the wall non-disassembly formwork 1 on one side, overlapping the two sides of the wall non-disassembly formwork 1 at the two ends of the wall frame, and fixing the non-disassembly steel formwork 11 of the wall non-disassembly formwork 1 to the wall frame by welding or self-tapping screws; filling the space between the wall frame and the wall non-disassembly formwork 1 with non-combustible Class A thermal insulation material , the non-combustible A-class thermal insulation material is at least one of rock wool, glass wool, perlite, vermiculite or recycled lightweight ceramsite to form the thermal insulation core 2; then install the wall non-disassembly formwork 1 on the other side, and fix the non-disassembly steel formwork 11 of the wall non-disassembly formwork 1 on the other side to the wall frame by welding or self-tapping screws, and the wall non-disassembly formwork 1 on both sides clamp the thermal insulation core 2; (3) lightweight concrete with a compressive strength of not less than 10Map is sprayed or applied to the steel mesh 12 of the wall non-disassembly formwork 1 and tamped, and then leveled and compacted, and the lightweight concrete fills the space between the steel mesh 12 and the non-disassembly steel formwork 11. The spraying or application of lightweight concrete needs to be carried out two or three times, and the last spraying is followed by compaction and leveling.

[0032] Through the above manufacturing method, an integrated insulation wall with a steel mesh truss and a non-removal template is obtained. During the wall production process, each integrated insulation wall is spliced ​​into a whole wall, and the leaf wall 3 can be sprayed on the whole surface to cover the steel mesh 12 and the wall frame. In step (3), for walls with doors, windows, water pipes, electrical conduit pipes, and switch boxes, the non-removal templates 1 of each wall are installed according to the pre-designed special construction plan, including the installation of each door and window opening, and the inspection is completed and qualified; the embedded water pipes, electrical conduits, switches, and socket embedded boxes are installed according to the design requirements. After the inspection is qualified, the steel mesh 12 that was cut due to the pre-embedding is reinforced, and reasonable protection and fixing measures are taken, and then the leaf wall 3 is sprayed and painted.

[0033] The integrated insulation wall produced in this embodiment is flexibly connected to the main structure, has a specified bearing capacity, and can adapt to the displacement capacity of the main structure. By setting reasonable expansion joints, the shrinkage stress of the wall material caused by temperature differences is controlled within the expansion joints, forming a waterproof, heat-insulating, thermally insulating, sound-insulating, and fire-proof non-load-bearing wall enclosure system.

[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 a correction layer 4 is provided between the insulation core 2 and the non-removal steel formwork 11 of the wall non-removal formwork 1 on both sides. The correction layer 4 is a heat-insulating and sound-insulating coating layer or a heat-insulating and sound-insulating pad. In this embodiment, the heat-insulating and sound-insulating pad is made of rock wool wrapped with aluminum foil. Of course, according to local energy-saving standards, multiple layers of aluminum foil or a double layer of heat-insulating and sound-insulating coating can also be used. Compared to the integrated insulation wall of Example 1, in addition to adjusting the thickness of the insulation core 2, this embodiment adds a correction layer 4. This facilitates the mass production of insulation cores 2 of the same thickness. By adding and adjusting the heat-insulating and sound-insulating correction layer, the existing energy-saving standards for near-zero energy buildings in the temperate southern region, which save 75%, and the energy-saving standards for ultra-low energy buildings in the cold northern region, which save 85%, are met.

[0035] Compared with Example 1, the manufacturing method of this embodiment is that in step (2), a correction layer 4 is further provided between the thermal insulation core 2 and the double-sided wall non-disassembly formwork 1, and the correction layer 4 is a double-layer thermal insulation and sound insulation paint layer or an additional thermal insulation and sound insulation pad brushed on the non-disassembly steel formwork 11.

[0036] The integrated thermal insulation wall produced by the present invention has high waterproof, thermal insulation, heat insulation, sound insulation and fireproof performance. No formwork needs to be erected or dismantled during the production process, and the existing building energy consumption and energy-saving standards are achieved at a relatively low cost. In addition, by adding a correction layer, the requirements of different building energy-saving standards in various places are met, the number of specifications for the thickness of the wall panel frame is reduced, and the versatility is higher. Recycled concrete from construction solid waste is used as the leaf wall 3, thereby achieving energy saving, environmental protection, and waste utilization.

[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.
