[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] Embodiment 1

[0019] like Figure 1-Figure 4 As shown, an embodiment of the utility model provides a prefabricated wall panel 1 with a mesh skeleton web, comprising four frame panels, the four frame panels are connected to form a wall panel outer frame, a web is embedded in the wall panel outer frame, the web is a concrete plate 15 with a mesh skeleton 14, the thickness of the concrete plate 15 is less than the thickness of the wall panel outer frame, and the four sides of the mesh skeleton 14 are fixedly connected to the inner plate surfaces of the four frame panels respectively.

[0020] Preferably, the four frame panels are a frame top panel 11, a frame bottom panel 12 and two frame side panels 13, wherein the frame top panel 11 and the frame bottom panel 12 are arranged opposite to each other, the two frame side panels 13 are arranged opposite to each other, and the panel surface of the frame side panel 13 is perpendicular to the panel surface of the frame top panel 11.

[0021] Among them, the mesh skeleton 14 is formed by interweaving multiple longitudinal wires and multiple transverse wires, the two ends of the longitudinal wires are respectively connected to the frame top plate 11 and the frame bottom plate 12, and the two ends of the transverse wires are respectively connected to the two frame side plates 13, so that the ends of each longitudinal wire respectively form the two sides of the mesh skeleton 14, and the ends of each transverse wire respectively form the other two sides of the mesh skeleton 14.

[0022] The web is a concrete slab 15 with a mesh frame 14 as the frame, that is, the mesh frame 14 is covered with concrete. Based on the above-mentioned wall panel outer frame structure, the concrete slab 15 can be poured without setting a peripheral formwork, which is convenient for the prefabrication production of the wall panel, and can effectively improve the prefabrication production efficiency of the wall panel and reduce the prefabrication production cost; for example, only one bottom form can be used, the wall panel outer frame with the mesh frame 14 can be placed on the bottom formwork, and then concrete can be poured to form the concrete slab 15.

[0023] The mesh structure of the mesh skeleton 14 can ensure its bonding with the concrete slab 15 , thereby improving the structural strength and stress-bearing performance of the prefabricated wall panel 1 .

[0024] The above-mentioned prefabricated wall panel 1 adopts a combined structure of wall panel outer frame + mesh skeleton 14 + concrete board 15. The outer frame structure and the mesh skeleton concrete structure can each play their own advantages and cooperate with each other to bear force, so that the wall panel has better structural performance and seismic resistance, etc. Therefore, the prefabricated wall panel 1 has good comprehensive performance and ensures its application effect.

[0025] Preferably, the thickness of the frame plate is in the range of 2 to 7 mm; the diameters of the longitudinal and transverse wires of the mesh skeleton 14 are in the range of 2 to 5 mm.

[0026] In one embodiment, the mesh skeleton 14 is a steel wire mesh or a composite material mesh, which can play a better role as a skeleton, and cooperate with the outer frame of the wall panel, etc. to ensure the stress performance and earthquake resistance of the wall panel. Preferably, the frame plate adopts a metal plate, and the mesh skeleton 14 correspondingly adopts a steel wire mesh, and the four sides of the mesh skeleton 14 are welded to the four frame plates respectively; or, the frame plate adopts a composite material plate, and the mesh skeleton 14 correspondingly adopts a composite material mesh. For the metal plate, it is preferred to use a steel plate. For the composite mesh / composite plate, building composite materials are generally used, including but not limited to using resin / rubber / ceramic as the base material, and using carbon fiber / glass fiber / basalt fiber as the reinforcing material.

[0027] The thickness of the concrete slab 15 is preferably smaller than the thickness of the wall panel outer frame. The thickness of the wall panel outer frame, i.e., the size of the wall panel outer frame in the direction perpendicular to the surface of the concrete slab 15, corresponds to the width of the frame top plate 11 / frame bottom plate 12. In this structure, an assembly cavity is formed on at least one side of the concrete slab 15. The assembly cavity is formed by the concrete slab 15 and four frame plates. The assembly cavity is a groove-shaped cavity, and the groove depth direction is perpendicular to the surface of the concrete slab 15. The assembly cavity can be used to set insulation materials / decorative panels at a later stage. Therefore, in some embodiments, the prefabricated wall panel 1 also includes an insulation layer and / or decorative panel embedded in the assembly cavity, that is, the prefabricated wall panel 1 is installed after the insulation layer and / or decorative panel are preinstalled offline. The insulation layer includes but is not limited to the use of insulation fire wall panels.

[0028] The prefabricated wall panel 1 based on the above structure adopts a web with a relatively small thickness, which can significantly reduce the weight of the wall panel and facilitate the subsequent wall construction.

[0029] Further preferably, the concrete slab 15 divides the inner cavity of the wall panel outer frame into two assembly cavities, and the two assembly cavities are arranged on both sides of the concrete slab 15 .

[0030] In an optional embodiment, the mesh skeleton 14 has multiple layers and is distributed sequentially along the thickness direction of the wall panel outer frame, which can correspondingly improve the structural strength, stiffness, stress bearing performance and seismic resistance of the prefabricated wall panel 1; each mesh skeleton 14 is covered by a concrete slab 15.

[0031] Preferably, the frame plate is provided with assembly holes for connecting to adjacent wall panels / columns, and bolt assembly can be performed between adjacent wall panels and between wall panels and columns; in particular, since the thickness of the web is less than the thickness of the wall panel outer frame, there is sufficient space to complete the bolt assembly operation, and therefore the assembly hole is connected to the above-mentioned assembly cavity.

[0032] In an optional embodiment, at least one of the frame panels is extended to form a flanged plate, and the flanged plate extends in the direction of the opposite frame panel and is respectively connected to the other two adjacent frame panels. The flanged plate can increase the structural strength and rigidity of the wall panel 1, and can also fix the outer decorative panel. Further, the two sides of the frame panel (corresponding to the inner side and the outer side of the wall) are respectively extended to form flanged plates; wherein, it is preferred that at least one of the frame side panels 13 is extended to form a flanged plate, and the flanged plate is respectively connected to the frame top panel 11 and the frame bottom panel 12; when all four frame panels are provided with flanged plates, the wall panel 1 can obtain higher structural strength and rigidity, and the installation of the outer decorative panel is also more convenient and reliable.

[0033] In one embodiment, if Figure 1 and Figure 2 The wall panel outer frame is a square structure, and the two frame side panels 13 are arranged in parallel.

[0034] In another embodiment, Figure 3 and Figure 4 At least one of the frame side panels 13 is an L-shaped side panel 130 with its corners protruding outward, and the angles between the two panels of the L-shaped side panel 130 and the thickness direction of the wall panel outer frame are both 45°; the frame top panel 11 and the frame bottom panel 12 match each other and have an L-shaped end 111 connected to the L-shaped side panel 130. It is easy to understand that the L-shaped end 111 is a right-angled isosceles triangle plate, and the frame top panel 11 / frame bottom panel 12 also includes a rectangular plate, and the corresponding side edges of the rectangular plate are connected to the bottom edge of the right-angled isosceles triangle plate.

[0035] The L-shaped side plate 130 is preferably made of angle steel.

[0036] The concrete slab 15 is connected to two inner wall surfaces of the L-shaped side plate 130 respectively, and roughly forms a U-shaped / meson-shaped connection structure.

[0037] When the two frame side panels 13 are both L-shaped side panels 130 , the notches of the two frame side panels 13 face each other, and the frame top panel 11 and the frame bottom panel 12 match each other and have two L-shaped end portions 111 .

[0038] In the above structure, the frame side panels 13 adopt L-shaped side panels 130 to facilitate connection with other wall panels at the intersection of the vertical and horizontal walls, so as to form a column-free structure at the intersection of the vertical and horizontal walls.

[0039] Embodiment 2

[0040] like Figure 5 This embodiment provides an assembled wall, which includes a plurality of prefabricated wall panels 1 provided in the first embodiment above, and each of the prefabricated wall panels 1 is assembled and connected to form a wall of a preset shape.

[0041] Among them, preferably, an insulation layer and / or a decorative panel is provided on the inner side of the wall of the web, and / or an exterior wall decorative panel is provided on the outer side of the wall of the web. This solution is particularly suitable for the case where the thickness of the concrete slab 15 is smaller than the thickness of the wall panel outer frame.

[0042] Among them, Figure 5 Preferably, at the intersection of the vertical and horizontal walls, the border side panels 13 of the prefabricated wall panels 1 are L-shaped side panels 130 with the corners protruding outwards, and the angles between the two plates of the L-shaped side panels 130 and the thickness direction of the corresponding wall panel outer frame are both 45°; the two adjacent border side panels 13 are butt-joined and assembled and fixed. In this structure, a column-free structure can be formed at the intersection of the vertical and horizontal walls, including but not limited to replacing L-shaped columns, T-shaped columns and cross-shaped columns, etc., so that not only the construction efficiency of the prefabricated wall can be effectively improved and the construction period can be shortened, but also the wall of the target structure can be assembled by using two types of wall panels, which can significantly reduce the cost of wall construction.

[0043] The prefabricated wall panel 1 with a square wall panel outer frame is the first wall panel 101, and the prefabricated wall panel 1 with an L-shaped side panel 130 as the frame side panel 13 is the second wall panel 102. At the intersection of the vertical and horizontal walls, two second wall panels 102 can be assembled into an L-shaped intersection node, and the L-shaped column at the node can be eliminated; at the intersection of the vertical and horizontal walls, three second wall panels 102 can be assembled into a T-shaped intersection node, and the T-shaped column at the node can be eliminated; at the intersection of the vertical and horizontal walls, four second wall panels 102 can be assembled into a cross-shaped intersection node, and the cross-shaped column at the node can be eliminated.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
