Description

Technical Field

[0001] This utility model belongs to the field of prefabricated buildings, and in particular relates to an interior partition wall. Background Technology

[0002] Current building wall technologies are diverse. Besides masonry blocks, most are constructed by assembling standard-width precast wall panels on-site. Hollow mesh walls also exist, using corrugated wire mesh to form a mesh, which is then plastered or sprayed with thin concrete. These walls offer good rigidity and integrity, making them less prone to cracking. However, they are heavy, and the corrugated wire mesh, being a unidirectional structure, while providing excellent vertical rigidity, suffers from poor horizontal rigidity and is prone to deformation. Therefore, the wire mesh must be assembled on-site.

[0003] In order to reduce the weight of the wire mesh wall, improve the bidirectional stiffness of the wire mesh, and enable the factory production of wire mesh assemblies, this utility model was developed.

[0004] It should be noted that the information disclosed in the background section of this utility model is intended only to enhance the understanding of the general background of this utility model, and should not be regarded as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to propose a wall that is lightweight and has good bidirectional stiffness.

[0006] To achieve this objective, the present invention provides an interior partition wall, comprising: A space truss, comprising a first flat space plate, a second flat space plate, and a corrugated back space plate, wherein the corrugated back space plate is connected between the first flat space plate and the second flat space plate, the first flat space plate is connected to the crest of the corrugated back space plate, and the second flat space plate is connected to the trough of the corrugated back space plate; The mortar layers are respectively formed and wrapped on the first flat mesh plate and the second flat mesh plate, and a sandwich layer is formed between the two mortar layers. The corrugated web mesh plate is located in the sandwich layer and is respectively connected in the two mortar layers.

[0007] Preferably, the crests and troughs of the wave-shaped mesh plate have a plane facing outwards, and the first flat mesh plate and the second flat mesh plate are fixed to the plane accordingly.

[0008] Preferably, the first flat mesh plate and the second flat mesh plate are fixed to the corrugated web mesh plate by welding, binding or gluing to the plane.

[0009] Preferably, the corrugated mesh plate, the first flat mesh plate, and the second flat mesh plate are steel wire mesh or expanded steel mesh.

[0010] Preferably, the sandwich layer is filled with a thermal insulator or a sound absorber.

[0011] Preferably, the wires of the corrugated mesh plate are obliquely interwoven.

[0012] Preferably, the inner angle of the waveform of the waveform mesh plate is 30~60°.

[0013] Preferably, the two sides of the truss are formed with edge sealing, which is formed by bending the side of the first flat truss; or, the edge sealing is formed by bending the side of the second flat truss; or, the edge sealing is formed by bending the side of the corrugated web truss.

[0014] Preferably, the number of the mesh trusses is at least two, the edge banding of adjacent mesh trusses is abutted, and the first flat mesh plate and the second flat mesh plate of adjacent mesh trusses extend outward and interlock.

[0015] The technical effects of the above-mentioned technical solution of this utility model are as follows: The factory uses a steel wire mesh core module (mesh truss) made of three steel wire meshes. The truss structure is formed by the wave "webs" perpendicular to the wave direction of the middle mesh. Along the wave direction of the middle mesh, a large number of diagonal steel wires act as "diagonal webs" and also form a truss structure. Therefore, it is a two-way force transmission spatial "mesh structure" with good two-way stiffness, making it suitable for handling and transportation without easily deforming.

[0016] At the same time, due to its extremely light weight (less than 4 kg / m²) 2 This allows the inner core to be 1.2m or even 1.8m wide while still being easy to handle manually, which is much larger than the 600mm width of traditional strips, greatly improving installation efficiency.

[0017] After the wire mesh core module is positioned on the construction site, it is coated or sprayed with mortar (or fine stone concrete) on both sides. The mortar will interlock with and wrap the wire mesh, thus forming a two-way wire mesh reinforced concrete wall with high rigidity and good integrity. More importantly, there is no need to install a keel for structural reinforcement.

[0018] The resulting wall has better bidirectional force transmission performance, which helps to disperse the concentrated force acting on the wall in two directions, which is equivalent to improving the out-of-plane stiffness of the wall.

[0019] Because the concrete thickness is small (20~25mm for the surface layer) and there is no concrete in the troughs of the wire mesh in the middle, the wall is lighter, saving concrete costs and reducing the seismic response of the structure.

[0020] Because the surface layer is plaster mortar, which replaces the leveling layer of traditional masonry walls, the overall cost is lower.

[0021] An air cavity is formed inside the wall (something that no previous wall could achieve unless a double-layer wall was made). The cavity forms a sound wave attenuation zone. Combined with the sound absorption characteristics of the uneven inner surface of the cavity caused by the wire mesh on the inside of the plastered surface, excellent noise reduction is achieved through the triple action of sound wave reflection, resonance suppression, and cavity damping.

[0022] The inner and outer walls are connected only by wire mesh, which reduces the sound transmission path and provides better sound insulation.

[0023] "Grid trusses" can be easily customized and produced. Compared to interior partition walls such as ALC panels and lightweight aggregate concrete hollow panels, they can be manufactured on-site with zero waste and minimal construction waste. (Panels often require cutting, resulting in more construction waste). Attached Figure Description

[0040] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. It should be noted that the aspects described below with reference to the accompanying drawings and specific embodiments are merely exemplary and should not be construed as limiting the scope of protection of the present invention in any way.

[0041] Structural Example: Please see Figures 1-9 This embodiment provides an internal partition wall, including a grid truss 1 and a mortar layer 2. The grid truss 1 includes a first flat grid plate 11, a second flat grid plate 12, and a corrugated mesh plate 13. The corrugated mesh plate 13 is connected between the first flat grid plate 11 and the second flat grid plate 12. The first flat grid plate 11 is connected to the crest 131 of the corrugated mesh plate 13, and the second flat grid plate 12 is connected to the trough 132 of the corrugated mesh plate 13. The two mortar layers 2 are respectively formed and wrapped around the first flat grid plate 11 and the second flat grid plate 12, forming a sandwich layer 10 between the two mortar layers 2. The corrugated mesh plate 13 is located in the sandwich layer 10 and is connected to the two mortar layers 2.

[0042] In this embodiment, the truss 1 is made of wire mesh. However, in the foreseeable future, it can be replaced by materials of equivalent or better strength. Wire mesh is a preferred choice in this embodiment. Specifically, the corrugated web plate 13, the first flat web plate 11, and the second flat web plate 12 are made of wire mesh or expanded metal mesh.

[0043] Please combine Figure 7 and Figure 9 The wire mesh core module forming the wall is a truss 1, which includes a three-layer mesh structure. The corrugated mesh plate 13 is located between the first flat mesh plate 11 and the second flat mesh plate 12. Furthermore, the crests 131 and troughs 132 of the corrugated mesh plate 13 have an outward-facing plane, and the first flat mesh plate 11 and the second flat mesh plate 12 are correspondingly fixed to this plane. That is, the tops of the crests 131 and troughs 132 of the corrugated mesh plate 13 are planar structures, facilitating the fixed installation of the first flat mesh plate 11 and the second flat mesh plate 12.

[0044] Specifically, the first flat mesh plate 11 and the second flat mesh plate 12 are fixed to the corrugated web mesh plate 13 by welding, binding or gluing. In this embodiment, welding is preferred.

[0045] Please combine Figure 7 , Figure 9 and combined Figure 5 A sandwich layer 10 is formed between the first flat mesh panel 11 and the second flat mesh panel 12. The sandwich layer 10 is filled with a thermal insulation material or a sound absorber to further achieve thermal insulation and sound insulation effects. The thermal insulation material or sound absorber can be made of foam material and filled in the sandwich layer 10.

[0046] In this embodiment, the factory uses three steel wire mesh core modules. Perpendicular to the wave direction of the middle mesh, the wave "webs" form a truss structure. Along the wave direction of the middle mesh, numerous diagonal steel wires act as "diagonal webs," also forming a truss structure. Therefore, it is a two-way force-transmitting spatial "space frame structure" with good two-way stiffness. Based on this two-way force-transmitting spatial "space frame structure," and with the addition of mortar layer 2, its stiffness is sufficient to meet the requirements of an internal partition wall, eliminating the need for a keel as in traditional internal formwork walls.

[0047] In this embodiment, the number of trusses 1 is determined according to the wall width. Several custom widths of trusses 1 are prefabricated in the factory, and can be assembled on-site according to the width requirements of different interior partition walls. Furthermore, edge banding 14 is formed on both sides of the trusses 1. The edge banding 14 is formed by bending the side of the first flat mesh plate 11 (e.g., ...). Figure 8 and Figure 9 Alternatively, the edge banding 14 is formed by bending the side of the second flat mesh 12 (e.g.) Figure 8 and Figure 9 Alternatively, the edge sealing 14 is formed by bending the side of the corrugated mesh plate 13 (e.g.) Figures 3-7 Specifically, when the number of grid trusses 1 is at least two or more, the sealing edges 14 of adjacent grid trusses 1 are attached together, and the first flat grid plate 11 and the second flat grid plate 12 of adjacent grid trusses 1 extend outward and interlock.

[0048] The beneficial effects of this embodiment: The factory uses a steel wire mesh core module (mesh truss) made of three steel wire meshes. The truss structure is formed by the wave "webs" perpendicular to the wave direction of the middle mesh. Along the wave direction of the middle mesh, a large number of diagonal steel wires act as "diagonal webs" and also form a truss structure. Therefore, it is a two-way force transmission spatial "mesh structure" with good two-way stiffness, making it suitable for handling and transportation without easily deforming.

[0049] At the same time, due to its extremely light weight (less than 4 kg / m²) 2 This allows the inner core to be 1.2m or even 1.8m wide while still being easy to handle manually, which is much larger than the 600mm width of traditional strips, greatly improving installation efficiency.

[0050] After the wire mesh core module is positioned on the construction site, it is coated or sprayed with mortar (or fine stone concrete) on both sides. The mortar will interlock with and wrap the wire mesh, thus forming a two-way wire mesh reinforced concrete wall with high rigidity and good integrity. More importantly, there is no need to install a keel for structural reinforcement.

[0051] The resulting wall has better bidirectional force transmission performance, which helps to disperse the concentrated force acting on the wall in two directions, which is equivalent to improving the out-of-plane stiffness of the wall.

[0052] Because the concrete thickness is small (20~25mm for the surface layer) and there is no concrete in the troughs of the wire mesh in the middle, the wall is lighter, saving concrete costs and reducing the seismic response of the structure.

[0053] Because the surface layer is plaster mortar, which replaces the leveling layer of traditional masonry walls, the overall cost is lower.

[0054] An air cavity is formed inside the wall (something that no previous wall could achieve unless a double-layer wall was made). The cavity forms a sound wave attenuation zone. Combined with the sound absorption characteristics of the uneven inner surface of the cavity caused by the wire mesh on the inside of the plastered surface, excellent noise reduction is achieved through the triple action of sound wave reflection, resonance suppression, and cavity damping.

[0055] The inner and outer walls are connected only by wire mesh, which reduces the sound transmission path and provides better sound insulation.

[0056] "Grid trusses" can be easily customized and produced. Compared to interior partition walls such as ALC panels and lightweight aggregate concrete hollow panels, they can be manufactured on-site with zero waste and minimal construction waste. (Panels often require cutting, resulting in more construction waste).

[0057] Furthermore, the present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
