Description

Technical Field

[0001] The present invention belongs to the technical field of building wall panels, and in particular relates to an assembled light steel integrated composite environmentally friendly wall panel system and a construction method thereof. Background Art

[0002] Light steel integrated composite environmentally friendly wall panels are mainly composed of light steel keels as the skeleton, supplemented by lightweight panels (such as gypsum boards, calcium silicate boards, etc.) and filling materials (such as insulation, sound insulation, and fireproof materials). This composite material structure makes the wall panels have sufficient strength and stability while maintaining a relatively light weight, which is easy to construct and install.

[0003] With the popularization of green building concepts and the continuous advancement of building technology, light steel integrated composite environmentally friendly wall panels are gradually being widely used as a new type of green building material. For example, after searching, there is a Chinese invention with a publication number of CN114961025A, which is an assembled anti-cracking light composite wall panel, which includes a middle base and two panels arranged on two opposite sides of the middle base, which is convenient for overall assembly, and the two panels are supported by triangular bent support ribs and fillers, which can absorb the stress of the panels and avoid cracking of the panels, and is easy to use.

[0004] Existing composite wall panels are generally prefabricated in factories, using light steel frames to build in light steel skeletons, which are then placed in molds and poured with fillers. After hardening and forming, they are sent to the construction site and fixed with bolts. A portion of the composite wall panels are installed on the outside of the building facing the outdoor environment. Due to thermal expansion and contraction, the expansion coefficients of the light steel frames and the poured fillers are different, causing expansion gaps at the junction of the two when exposed to cold. The built-in light steel skeleton only supports these poured fillers in one direction, making it difficult to take into account the fit between the four sides of the light steel frame and the poured fillers. Summary of the invention

[0005] The purpose of the present invention is to provide an assembled light steel integrated composite environmentally friendly wall panel system and a construction method thereof, in which an inner frame and inclined tie bars provide three-dimensional support for pouring fillers and tighten the outer frame from the inside, taking into account the fit between the four sides of the inner and outer frames and the filler pieces, thereby reducing the expansion gap generated at the adhesion between the two when they are cooled.

[0006] The technical solution adopted by the present invention is as follows:

[0007] An assembled light steel integrated composite environmentally friendly wall panel system includes a cross beam, two frames and a bottom beam fixed in sequence from top to bottom, and also includes:

[0008] A first curved panel, wherein the first curved panel is wavy and has flanges a and flanges b welded alternately on both sides, the flanges a and flanges b have opposite curvatures, and the flanges a and flanges b are welded with first angle irons on the sides away from the first curved panel, and two first limit strips arranged side by side are fixed on the outer curved surface of the first curved panel;

[0009] A second curved plate, the second curved plate is also wavy and has flanges c and flanges d welded alternately on both sides, the flanges c and flanges d have opposite curvatures, and the flanges c and flanges d are welded with second angle irons on the sides away from the second curved plate, and two second limit bars arranged side by side are fixed on the outer curved surface of the second curved plate;

[0010] A grid unit, wherein the cross beam, two frames and the bottom beam are assembled into an outer frame, the first curved panel and the second curved panel are cross-assembled into an inner frame, the inner portion of the outer frame is divided into grid units by the inner frame, a filler and an oblique tie bar wrapped by the filler are arranged inside the grid unit, and the filler is pulled by the first angle iron and the second angle iron, and the oblique tie bars are arranged along the diagonal of the grid unit;

[0011] Take the composite environmentally friendly wall panel and insert it vertically into the reserved holes in the stair frame. You can use screws to penetrate the wall to fix it, which is convenient and quick to assemble. Once the outdoor temperature drops, the entire composite environmentally friendly wall panel will be cold, and the expansion coefficients of the inner and outer skeletons and the cast filler are different. The edge of the filler piece and the inner side of the outer skeleton are tightly attached. Among them, the curved first curved panel and the second curved panel can support the cast filler along the X and Y axes, and their curved sides can support the cast filler along the Z axis. Diagonal braces are added to increase the connection area between the inner skeleton and the cast filler while dividing the grid unit into two spatial triangles, which are more stable. The cast filler is supported in three dimensions by the inner skeleton and the diagonal braces, and the outer skeleton is tightened from the inside, taking into account the fit between the four sides of the inner and outer skeletons and the filler pieces, reducing the expansion gap between the adhesion between the two when it is cold, which is convenient for improving the overall bending and shear resistance of the composite environmentally friendly wall panel.

[0012] As a preferred solution, a first slot is spaced apart on one side of the first curved panel, and a second slot opposite to the first slot is spaced apart on one side of the second curved panel. The second slot is nested with the first slot to realize the assembly of the first curved panel and the second curved panel. The second slot and the first slot are staggered with the first angle iron and the second angle iron. During assembly, due to the mutual adaptation of the second slot and the first slot, the first curved panel and the second curved panel are guided, and can be quickly put into place and crossed together, and a gap can be left for welding and fixing at the cross position.

[0013] As a preferred solution, the oblique tie bar includes two outer ring parts welded in an "8" shape along the diagonal line inside the grid unit, and the inner ring parts are vertically welded inside the two outer ring parts. The inner ring parts and adjacent outer ring parts are assembled into a hollow mesh cage. During assembly, the outer ring parts and the inner ring parts are first cross-welded together to form a hollow mesh cage, wherein the hollow mesh cage can be deformed with the inner skeleton before pouring the filler parts, and after pouring the filler parts, the inner skeleton supports the filler parts toward the hollow mesh cage to form a clamping effect, so that the hollow mesh cage and the inner skeleton cooperate with each other, and the hollow mesh cages are welded end to end to form oblique tie bars, and several spare ones are prepared. After being loaded into the grid unit, the poured filler can smoothly enter the hollow mesh cage, mix with the oblique tie bars and connect seamlessly, so that the connection between the inner skeleton and the filler parts is closer.

[0014] As a preferred embodiment, the filler comprises aggregate arranged inside the grid unit and two mesh layers wrapped by the aggregate, the edges of the two mesh layers respectively hook the adjacent first angle iron and the second angle iron, the two mesh layers are respectively wrapped with oblique tension bars from both sides, both ends of the aggregate extend out of the grid unit, both sides of the exoskeleton are coated with fireproof surface layers, the inner sides of the two fireproof surface layers extend into the exoskeleton and bonded to one end of the aggregate, when pouring, first wrap the two sides of each oblique tension bar with mesh layers, glue can be used to glue the two mesh layers at multiple points, and then the aggregate and the fireproof surface layers are poured in turn, the mesh layer serves as an extension of the oblique tension bar, which can pull a wider area of ​​the aggregate, so that the entire filler is more firmly attached to the inner skeleton and is not easy to fall off or crack, especially the flexible mesh layer, which can extend freely in the grid unit and be attached to the surface of the inner skeleton over as large an area as possible.

[0015] As a preferred solution, corrugated grooves are provided on the sides of the two frames that are away from each other. The corrugated grooves are used to accommodate mortar. Especially when the composite environmentally friendly wall panels are connected to each other, the side seams are often filled with mortar. The corrugated grooves increase the bonding area of ​​the mortar to improve the firmness of the assembly.

[0016] As a preferred solution, a connecting piece is inserted between two adjacent corrugated grooves. The connecting piece is vertically wavy and its surface can be coated with flux. The two composite environmentally friendly wall panels are pulled across by the connecting piece so that the composite environmentally friendly wall panels can be held hand in hand. Especially after the connecting piece is spot-welded by a welding gun, the assembly is more secure and the side seams are not easy to come loose or crack.

[0017] As a preferred solution, steel columns are welded on the lower surface of the bottom beam. During installation, the steel columns are inserted into long grooves on the ground to guide the external skeleton. The long grooves can be filled with cement mortar later. After hardening, these steel columns are fixed. The steel columns are used to horizontally support the composite environmentally friendly wall panels to prevent horizontal deviation.

[0018] As a preferred solution, assembly grooves are provided on both sides of the two frames that are away from each other. After installation, the assembly grooves are used to weld steel plates at the connecting seams of the two outer skeletons. Mortar or seam beautifier can then be applied to the side seams to be beautify them while bonding them, making it convenient for multiple composite environmentally friendly wall panels to form an integrated whole, which is beautiful and elegant.

[0019] As a preferred solution, the outer surfaces of the two fire-proof surface layers are coated with an environmentally friendly coating, preferably a coating made of a mixture of silicate and calcium oxide as the main body, which has the advantages of fire resistance, high temperature resistance, corrosion resistance, and strong weather resistance. In particular, their surfaces are hard and flat, making the entire wall surface neat and tidy, and are not easy to crack and deform after being pulled by the internal and external skeletons and the inclined reinforcement.

[0020] A method for constructing an assembled light steel integrated composite environmentally friendly wall panel includes two stages:

[0021] First, the prefabrication stage:

[0022] Step 1: Cut the steel plate to make a crossbeam, two frames, and a bottom beam, and weld them into an outer frame;

[0023] Step 2: After the first curved panel and the second curved panel are bent and formed, they are cross-assembled, spot-welded at the intersection, and the inclined tie bars are welded in the grid unit to form an inner frame, which is then placed in the outer frame and welded and fixed;

[0024] Step 3: First, wrap the mesh layer on both sides of each inclined reinforcement;

[0025] Step 4: Place the exoskeleton flat into the mold, pour the aggregate and fireproof surface layer in sequence, and use a flat plate to level it;

[0026] Step 5: The filler parts are hardened and firmly bonded to the four sides of the outer frame to form assembled light steel composite environmentally friendly wall panels, which are then demoulded and set aside.

[0027] Second, the installation phase:

[0028] Step 6: Take the composite environmentally friendly wall panel and insert it vertically into the reserved hole of the stair frame. You can use screws to penetrate the wall to fix it;

[0029] Step 7: Once the composite environmentally friendly wall panel is cooled, the curved first curved panel and the second curved panel can support the pouring of fillers along the X and Y axes, and their curved sides can support the pouring of fillers along the Z axis. The inner skeleton and the inclined reinforcement provide three-dimensional support for the pouring of fillers and tighten the outer skeleton from the inside, taking into account the fit between the four sides of the inner and outer skeletons and the filler pieces, reducing the expansion gap between the two when the adhesion is cooled.

[0030] The technical effects achieved by the present invention are:

[0031] The present invention takes the composite environmentally friendly wall panel and vertically inserts it into the reserved hole of the stair frame, and can be fixed by penetrating the wall with screws, which is convenient and quick to assemble. Once the outdoor temperature drops, the entire composite environmentally friendly wall panel is cold, and the expansion coefficients of the inner and outer skeletons and the cast filler are different. The edge of the filler piece and the inner side of the outer skeleton are tightly attached, wherein the curved first curved panel and the second curved panel can support the cast filler along the X and Y axes, and their curved flanges a, flanges b, flanges c and flanges d can support the cast filler along the Z axis, and oblique tension bars are added to increase the connection area between the inner skeleton and the cast filler while dividing the grid unit into two spatial triangles, which has higher stability. The cast filler is three-dimensionally supported by the inner skeleton and the oblique tension bars, and the outer skeleton is tightened from the inside, taking into account the fit between the four sides of the inner and outer skeletons and the filler piece, reducing the expansion gap generated when the adhesion between the two is cold, which is convenient for improving the overall bending and shear resistance of the composite environmentally friendly wall panel.

[0032] During assembly, the outer ring and the inner ring are first cross-welded to each other to form a hollow mesh cage, and the hollow mesh cages are welded end to end to form oblique reinforcements, and a number of spares are prepared. After the grid units are loaded, the poured filler can smoothly enter the hollow mesh cage, mix with the oblique reinforcements and connect seamlessly, so that the connection between the inner skeleton and the filler is closer.

[0033] During pouring, the present invention first wraps both sides of each oblique tie bar with mesh layers, and glue can be used to stick the two mesh layers at multiple points. The edges of the two mesh layers respectively hook the adjacent first angle iron and the second angle iron, so that the mesh layers are not easy to fall off. Aggregates and fireproof surface layers are then poured in sequence. The mesh layers serve as extensions of the oblique tie bars, and can pull a wider area of ​​the aggregates, so that the entire filler piece is more firmly attached to the inner skeleton and is not easy to fall off or crack. In particular, the flexible mesh layer can extend freely in the grid unit and be attached to the surface of the inner skeleton over as large an area as possible.

[0034] The present invention forms an assembled light steel composite environmentally friendly wall panel in the prefabrication stage through steps one to seven, taking into account the characteristics of high structural strength, environmental protection, fire resistance, crack resistance, etc., and then demolding for use. In the subsequent installation stage, the composite environmentally friendly wall panel is vertically inserted into the reserved holes of the stair frame, and can be fixed by penetrating screws into the wall. Once the composite environmentally friendly wall panel is cooled, the inner frame and the inclined tie bars are three-dimensionally supported to cast the filler and tighten the outer frame from the inside, taking into account the fit between the four sides of the inner and outer frames and the filler pieces, reducing the expansion gap generated at the adhesion between the two after being cooled. The construction steps are clear and distinct, which is different from other composite wall panels on the market, ensuring that the quality of the composite environmentally friendly wall panel after construction is similar, especially in the cold northern regions, it can have good anti-cracking and anti-edge seam detachment performance.

[0048] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention, and does not strictly limit the scope of protection of the specific claims of the present invention.

[0049] Embodiment 1:

[0050] like Figure 1-Figure 10 As shown, an assembled light steel integrated composite environmentally friendly wall panel system includes a cross beam 1, two frames 2 and a bottom beam 3 fixed in sequence from top to bottom, and also includes: a first curved panel 4, a second curved panel 6 and a grid unit 8.

[0051] The first curved panel 4, the number of the first curved panels 4 can be multiple, in the present embodiment preferably 7 first curved panels 4 are distributed along the vertical array, the first curved panel 4 can be processed by a bending machine into a wavy shape and both sides are alternately welded with flanges a401 and flanges b402, the flanges a401 and flanges b402 have opposite curvatures respectively, the flanges a401 and flanges b402 away from the first curved panel 4 are welded with first angle irons 403, and the outer curved surface of the first curved panel 4 has two side-by-side first limiting strips 5 welded thereon.

[0052] The second curved panel 6, the number of the second curved panels 6 can also be multiple. In the present embodiment, preferably 5 second curved panels 6 are distributed along the vertical array. The second curved panel 6 can also be processed into a wavy shape by a bending machine and both sides are alternately welded with flanges c601 and flanges d602. The flanges c601 and flanges d602 have opposite curvatures respectively. The sides of the flanges c601 and flanges d602 away from the second curved panel 6 are welded with second angle irons 603. The outer curved surface of the second curved panel 6 has two side-by-side second limiting strips 7 welded thereon.

[0053] The grid unit 8, the cross beam 1, the two frames 2 and the bottom beam 3 are assembled into an outer frame, the first curved panel 4 and the second curved panel 6 are cross-assembled into a mesh inner frame, the interior of the outer frame is divided into grid units 8 by the inner frame, and the grid unit 8 is provided with fillers and oblique tie bars wrapped by the fillers, and the oblique tie bars are all arranged along the diagonal lines of the grid unit 8.

[0054] At present, manufacturers can prefabricate composite environmentally friendly wall panels of different sizes according to customer needs. Steel plates are cut according to the dimensions on the drawings to form a crossbeam 1, two frames 2, and a bottom beam 3. The two ends of the two frames 2 are respectively welded to the two ends of the crossbeam 1 and the two ends of the bottom beam 3 as an outer frame, and the first curved panel 4 and the second curved panel 6 can be cut off after bending and forming, and after cross-assembly, they are placed on an automatic laser welding machine for spot welding at the intersection of the two, and oblique tie bars are welded in the grid unit 8, and the filler pieces are pulled by the first angle iron 403 and the second angle iron 603. After continuous welding, they are cut off at a fixed length as an inner frame, and then placed in the outer frame for welding and fixing.

[0055] During pouring, place the exoskeleton flatly into the mold, pour in the evenly mixed filler with a hopper, and use a flat plate to flatten it. After a period of time, the filler hardens and adheres to the four sides of the exoskeleton to form a composite environmentally friendly wall panel, which can then be demolded for use.

[0056] During installation, the composite environmentally friendly wall panel is vertically inserted into the reserved holes of the stair frame, and can be fixed by screwing into the wall, which is convenient and quick to assemble. Once the outdoor temperature drops, the entire composite environmentally friendly wall panel is cold, and the expansion coefficients of the inner and outer frames and the poured fillers are different. The edge of the filler piece and the inner side of the outer frame are tightly attached. Among them, the curved first curved panel 4 and the second curved panel 6 can support the poured fillers along the X and Y axes respectively. Because the flange a401 and the flange b402 both have a certain angle relative to the first curved panel 4, and the flange c601 and the flange d602 both have a certain angle relative to the second curved panel 6, they are respectively "curved" The U" shape can wrap the poured filler while supporting the poured filler along the Z axis, and the filler piece is pulled by the burr-shaped first angle iron 403 and the second angle iron 603 to strengthen the tightness of the connection between the filler piece and the inner frame, and the inclined reinforcement is added to increase the connection area between the inner frame and the poured filler while dividing the grid unit 8 into two spatial triangles, which is more stable. The poured filler is supported in three dimensions by the inner frame and the inclined reinforcement and the outer frame is tightened from the inside, taking into account the fit between the four sides of the inner and outer frames and the filler piece, reducing the expansion gap generated when the adhesion between the two is cold, so as to improve the overall bending and shear resistance of the composite environmentally friendly wallboard.

[0057] See attached Figure 4 , Figure 7 and Figure 8 A first card slot 9 is provided at one side of the first curved panel 4, and a second card slot 10 opposite to the first card slot 9 is provided at one side of the second curved panel 6. The second card slot 10 and the first card slot 9 are nested together to realize the assembly of the first curved panel 4 and the second curved panel 6. The second card slot 10 and the first card slot 9 are staggered with the first angle iron 403 and the second angle iron 603. During assembly, due to the mutual adaptation of the second card slot 10 and the first card slot 9, the first curved panel 4 and the second curved panel 6 are guided, and can be quickly placed in place and crossed together, and a gap can be left for welding and fixing at the crossing position.

[0058] Among them, the first limiting strip 5 and the second limiting strip 7 increase the layered connection between the inner frame and the poured filler, facilitate limiting, and prevent the poured filler from sliding along the curved surface of the inner frame.

[0059] See attached Figure 3 , Figure 4 and Figure 6The oblique tie bars include two outer rings 11 welded in the shape of "8" along the diagonal line inside the grid unit 8, and the inner rings 12 are vertically welded inside the two outer rings 11. The inner rings 12 and the adjacent outer rings 11 are assembled into a hollow mesh cage, wherein the hollow mesh cage can be deformed with the inner frame before pouring the filler, and after pouring the filler, the inner frame supports the filler toward the hollow mesh cage to form a clamping effect, so that the hollow mesh cage and the inner frame cooperate with each other, especially the flange a401, The wrapping structure of flange b402, flange c601 and flange d602 can push the poured filler into the hollow mesh cage better. During assembly, the outer ring 11 and the inner ring 12 are first cross-welded together to form a hollow mesh cage. The hollow mesh cages are welded end to end to form diagonal reinforcements, and several spare ones are prepared. After the grid unit 8 is loaded, the poured filler can smoothly enter the hollow mesh cage, mix with the diagonal reinforcements and connect seamlessly, making the connection between the inner skeleton and the filler pieces closer.

[0060] See attached Figure 1 and Figure 2 The filler includes an aggregate 14 arranged inside the grid unit 8 and two mesh layers 13 wrapped by the aggregate 14. The edges of the two mesh layers 13 respectively hook the adjacent first angle iron 403 and the second angle iron 603, so that the mesh layer 13 is not easy to fall off. The mesh layer 13 can be woven into a sheet by nylon fiber. The two mesh layers 13 are respectively wrapped with oblique tension bars from both sides. The aggregate 14 is composed of cement mortar, glass fiber, slag, etc. Both ends of the aggregate 14 extend out of the grid unit 8. Both sides of the exoskeleton are coated with a fireproof surface layer 15, and the fireproof surface layer 15 can be made of rock wool. The inner sides of the two fireproof surface layers 15 extend into the interior of the outer frame and are bonded to one end of the aggregate 14. When pouring, the mesh layer 13 is first wrapped on both sides of each inclined reinforcement, and the two mesh layers 13 can be glued at multiple points with glue, and then the aggregate 14 and the fireproof surface layer 15 are poured in turn. The mesh layer 13 serves as an extension of the inclined reinforcement, which can pull the aggregate 14 to a wider area, so that the entire filler is more firmly attached to the inner frame and is not easy to fall off or crack. In particular, the flexible mesh layer 13 can extend freely in the grid unit 8 and be attached to the surface of the inner frame over as large an area as possible.

[0061] See attached Figure 1 and Fig. 9 The two frames 2 are provided with corrugated grooves 16 on the sides away from each other. The corrugated grooves 16 are used to accommodate mortar. Especially when the composite environmentally friendly wall panels are connected to each other, the side seams are often filled with mortar. The corrugated grooves 16 increase the bonding area of ​​the mortar to improve the firmness of the assembly.

[0062] See attached Figure 1 , Fig. 9 and Fig.10A connector 17 is inserted between two adjacent corrugated grooves 16. The connector 17 is made of the same material as the outer frame. The connector 17 is vertically wavy and its surface can be coated with flux. The two composite environmentally friendly wall panels are pulled across by the connector 17, so that the composite environmentally friendly wall panels are hand in hand. Especially after the connector 17 is spot-welded with a welding gun, the assembly is more secure and the side seams are not easy to come off or crack.

[0063] See attached Figure 1 and Figure 5 A steel column 18 is welded on the lower surface of the bottom beam 3. During installation, the steel column 18 is inserted into a long groove on the ground to guide the external frame. The long groove can be filled with cement mortar in the later stage. After hardening, these steel columns 18 are fixed. The steel columns 18 are used to horizontally support the composite environmentally friendly wall panels to prevent horizontal deviation.

[0064] See attached Figure 1 and Fig. 9 The two sides of the two frames 2 away from each other are provided with assembly grooves 19. After installation, the assembly grooves 19 are used to weld steel plates at the connecting seams of the two outer skeletons. Mortar or seam beautifying agent can be applied to the side seams, and the side seams can be beautified while bonding, so that multiple composite environmentally friendly wall panels can be integrated into one, which is beautiful and generous.

[0065] See attached Figure 1 and Figure 2 The outer surfaces of the two fireproof surface layers 15 are coated with an environmentally friendly coating 20. The environmentally friendly coating 20 can be any one of water-based coatings, UV-curing coatings, nano coatings, biomass coatings and inorganic coatings. In this embodiment, it is preferably a coating made of a mixture of silicate and calcium oxide as the main body. It has the advantages of fire resistance, high temperature resistance, corrosion resistance, and strong weather resistance. In particular, their surfaces are hard and flat, making the entire wall surface neat and tidy, and are not easy to crack and deform after being pulled by the internal and external skeletons and the inclined reinforcement.

[0066] Embodiment 2:

[0067] Since there are many composite wall panels on the market, and the manufacturing processes are different, we improve the construction method of traditional composite wall panels, so as to ensure that the quality of the composite environmentally friendly wall panels given in Example 1 after construction is similar, especially in the cold northern regions, it can have good anti-cracking and anti-seam detachment performance.

[0068] like Fig.11 As shown, a method for constructing assembled light steel integrated composite environmentally friendly wall panels is mainly divided into two stages:

[0069] First, the prefabrication stage:

[0070] Step 1: Composite environmentally friendly wall panels of different sizes can be prefabricated according to customer needs. Steel plates are cut according to the size of the drawing to make a crossbeam 1, two frames 2, and a bottom beam 3. The two ends of the two frames 2 are welded to the ends of the crossbeam 1 and the ends of the bottom beam 3 as an external skeleton;

[0071] Step 2: The first curved panel 4 and the second curved panel 6 can be cut off after being bent and formed, and after cross-assembly, they are placed on an automatic laser welding machine to spot weld the intersection of the two, and the inclined tie bars are welded in the grid unit 8. After continuous welding, they are cut off at a fixed length as the inner frame, and then placed in the outer frame for welding and fixing;

[0072] The outer ring member 11 and the inner ring member 12 are first cross-welded together to form a hollow mesh cage, and the hollow mesh cages are welded end to end to form inclined tie bars, and several spares are prepared before they can be installed in the mesh unit 8;

[0073] Step 3: First, wrap the two sides of each inclined reinforcement with a mesh layer 13, and glue can be used to glue the two mesh layers 13 at multiple points;

[0074] Step 4: Place the outer frame flat into the mold, and pour the aggregate 14 and the fireproof surface layer 15 in turn. The mesh layer 13 is used as an extension of the inclined reinforcement to pull the aggregate 14 to a wider area, so that the entire filler is more firmly attached to the inner frame and is not easy to fall off or crack. In particular, the flexible mesh layer 13 can be freely extended in the grid unit 8 and attached to the inner frame surface with as large an area as possible;

[0075] Then pour the evenly mixed filler into the hopper and flatten it with a flat plate;

[0076] Step 5: The filler is hardened and adhered to the four sides of the outer frame, so that the aggregate 14 is the main body and the outer frame of the light steel material is formed into an integrated body to form an assembled light steel composite environmentally friendly wallboard, which takes into account high structural strength, environmental protection, fire resistance, crack resistance and other characteristics, and then demolded for use.

[0077] Second, the installation phase:

[0078] Step 6: Take the composite environmentally friendly wall panel and insert it vertically into the reserved holes of the stair frame. You can use screws to penetrate the wall to fix it, which is convenient and quick to assemble;

[0079] Step seven: Once the outdoor temperature drops, the entire composite environmentally friendly wall panel becomes cold, and the expansion coefficients of the inner and outer frames and the cast fillers are different. Among them, the curved first curved panel 4 and the second curved panel 6 can support the cast fillers along the X and Y axes, and their curved sides can support the cast fillers along the Z axis. Diagonal reinforcement is added to increase the connection area between the inner frame and the cast fillers while dividing the grid unit 8 into two spatial triangles, which is more stable. The cast fillers are supported in three dimensions by the inner frame and the diagonal reinforcement, and the outer frame is tightened from the inside, taking into account the fit between the four sides of the inner and outer frames and the fillers, reducing the expansion gap between the adhesion between the two when it is cold, so as to improve the overall bending and shear resistance of the composite environmentally friendly wall panel.

[0080] The above is only a preferred embodiment of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the art unless otherwise specified and limited.
