Description

Technical Field

[0001] The present application relates to the technical field of wall panels, and in particular to a multifunctional wall panel and a connection structure. Background Art

[0002] Wall panels are a house structure with a load-bearing system composed of walls and floor slabs. Simply put, it is a new type of wall material that has developed with the rise of prefabricated large-panel buildings. Its materials and styles are diverse. Currently, the wall panels available on the market include PVC wall panels, stone plastic panels, bamboo fiber wall panels, and wooden wall panels. The public can choose to decorate and beautify their homes according to their personal preferences.

[0003] Wall panels can be divided into exterior wall panels and interior partitions according to their functions. Exterior wall panels include front exterior wall panels, gable wall panels and eave wall panels. Front exterior wall panels are self-bearing wall panels, while gable wall panels and eave wall panels are load-bearing wall panels. Interior partitions include horizontal wall panels, vertical wall panels and partition panels. Both horizontal wall panels and vertical wall panels are load-bearing wall panels, while partition panels are non-load-bearing wall panels.

[0004] Since wall panels are divided into exterior wall panels and interior partition walls, and due to their different functions, there is a large difference in their strength, hardness and load-bearing capacity. This results in that current conventional wall panels cannot be mixed and have relatively single functions. Utility Model Content

[0005] In order to improve the situation that conventional wall panels have relatively single functions, the present application provides a multifunctional wall panel and a connection structure.

[0006] On the one hand, the present application provides a multifunctional wall panel, which adopts the following technical solution:

[0007] A multifunctional wall panel comprises a core panel, wherein the core panel is provided with supporting layers on all sides along the height direction thereof, the supporting layers surround the core panel, a magnesium oxychloride layer is filled between the core panel and the supporting layer, the outer side of the supporting layer away from the core panel is also coated with a magnesium oxychloride layer, the magnesium oxychloride layer wraps the supporting layer, the core panel, the supporting layer and the magnesium oxychloride layer together constitute the main body of the wall panel, and the magnesium oxychloride layer is made of magnesium oxychloride cement material.

[0008] By adopting the above technical scheme, the core board serves as a backbone and can provide stable support for the formation of the wall panel body. The outer periphery of the core board is coated with a supporting layer, and a magnesium oxychloride layer is filled between the supporting layer and the core board, so that the supporting layer and the core board are combined together to form the supporting body of the wall panel body. At the same time, a magnesium oxychloride layer is also coated outside the supporting layer, and the magnesium oxychloride layer wraps all the supporting layers and the core board located inside to form a complete wall panel body. The magnesium oxychloride layer is made of magnesium oxychloride cement material. The magnesium oxychloride cement has the characteristics of high strength, fire resistance, early strength, frost resistance, and resistance to salt and alkali corrosion. The wall panel body formed by wrapping and pouring the magnesium oxychloride cement has sufficient strength, so that the wall panel body can be used as an exterior wall panel, an interior partition wall or a floor slab at the same time, which greatly improves the use function of the wall panel body.

[0009] Optionally, the core board is made of lightweight concrete or foam insulation board.

[0010] By adopting the above technical solution, the core board is made of lightweight concrete or foam insulation board material, so that the core board has the function of thermal insulation and sound insulation, and at the same time can effectively reduce the weight of the core board itself, thereby reducing the overall weight of the wall panel body, making the wall panel body have the characteristics of lightweight.

[0011] Optionally, a plurality of pipeline holes are opened in the core plate, the plurality of pipeline holes are parallel to each other and penetrate the core plate along the height direction of the core plate, and the pipeline holes are used for placing wire tubes.

[0012] By adopting the above technical solution, the pipe holes opened inside the core board can facilitate the installation of wire pipes during the later construction, so that there is no need for on-site grooving during the later construction process, which effectively improves the construction efficiency.

[0013] Optionally, the support layer includes support plates surrounding the core plate, and the support plates at two long sides perpendicular to the height direction of the core plate are formed by staggered splicing of multiple support strips.

[0014] By adopting the above technical solution, the support panels at the two long sides perpendicular to the height direction of the core panel are formed by staggered splicing of multiple support strips, so that the support panels can be composed of many smaller support strips. When making the main body of the wall panel, the purchase price of the whole panel is obviously higher than the price of multiple support strips. Therefore, using multiple support strips to splice the support panels can effectively reduce the company's procurement costs.

[0015] Optionally, a mesh cloth is laid on a side of the support strips away from the core board, and the mesh cloth covers all the support strips located on the same side of the core board.

[0016] By adopting the above technical solution, the mesh cloth covers all the supporting strips on the same side. During the subsequent pouring of magnesium oxychloride cement, the mesh cloth can improve the stability of the connection between the supporting strips and reduce the possibility of cracking of the supporting strips.

[0017] Optionally, a groove is provided on the outer side of the magnesium oxychloride layer perpendicular to the two wide sides in the height direction of the core board, the groove penetrates the outermost magnesium oxychloride layer in the height direction of the core board, and the groove is provided at the midline of the two wide sides in the height direction of the core board.

[0018] By adopting the above technical solution, when the wall panel body is connected to other components, the reserved grooves are convenient for filling with sound-absorbing materials, and the sound-absorbing materials subsequently filled in the grooves can fill the connecting gaps between the wall panel body and other components, which can effectively reduce the sound transmission through the seams and the smoke transmission in the event of fire.

[0019] Optionally, the thickness of the magnesium oxychloride layer at the two wide sides perpendicular to the core board height direction gradually becomes thinner from the middle to both sides, forming a hypotenuse symmetrical with respect to the midline of the two wide sides along the core board height direction.

[0020] By adopting the above technical solution, the magnesium oxychloride layer at the two wide sides perpendicular to the core board height direction is provided with beveled edges. When the wall panel body is connected with other components, an outward opening is formed between the reserved beveled edges and the other components, which facilitates the subsequent filling of the gap between the wall panel body and the other components with adhesive materials.

[0021] Optionally, concave grooves are provided at both edges of the magnesium oxychloride layer at positions perpendicular to the two long sides in the height direction of the core plate.

[0022] By adopting the above technical solution, recessed tongues and grooves are provided at the two edges of the outermost magnesium oxychloride layer. When two wallboard bodies are butt-jointed, the space formed by the two adjacent tongues and grooves is convenient for construction workers to fill in adhesive materials.

[0023] On the other hand, the present application provides a multifunctional wall panel connection structure, using any of the multifunctional wall panels described above, as well as sound insulation materials and adhesive materials, when the wall panel body is connected to other components, the sound insulation material is filled in the groove, and the adhesive material is filled in the gap between the wall panel body and other components;

[0024] When two wall panel bodies are butt-jointed, a mesh cloth is laid in the space formed by two adjacent tongues and grooves and filled with bonding material.

[0025] By adopting the above technical solution, when the wall panel body is connected to other components, sound insulation material can be filled in the groove, the sound insulation material can fill the gap, reduce the sound transmission through the gap, and improve the sound insulation effect of the wall panel body. Subsequently, the adhesive material is filled in the gap formed between the inclined surface of the wall panel body and other components. Finally, a mesh cloth is laid in the space formed by two adjacent tongues and grooves, and filled with adhesive material. The laid mesh cloth can effectively improve the connection stability between the wall panel body and other components and reduce cracking.

[0026] In summary, the present application includes at least one of the following beneficial effects:

[0027] 1. The wallboard body is formed by filling and coating with a core board, a support board and a magnesium oxychloride layer. The magnesium oxychloride layer can effectively improve the overall strength of the wallboard body. At the same time, the core board and the support board serve as the supporting body, so that the wallboard body can be used as an exterior wallboard, an interior partition wall or a floor board at the same time, effectively improving the use function of the wallboard body;

[0028] 2. By using preset pipe holes inside the core board, the preset pipe holes can be used to pass wire pipes in subsequent construction, so that subsequent construction does not require on-site grooving, thereby improving construction efficiency;

[0029] 3. By laying a mesh cloth on the outside of the support plate, the mesh cloth can effectively improve the stability of the connection between the support strips. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] Embodiment 1:

[0037] Embodiment 1 of the present application discloses a multifunctional wall panel, referring to Figure 1 and Figure 2 The multifunctional wall panel includes a core panel 2, and the core panel 2 is covered with support panels 3 on all sides. The support panels 3 cover the core panel 2 to surround the core panel 2. The core panel 2 is used as the main trunk, and the support panels 3 surrounding the core panel 2 together form a wall panel body 1. In Example 1 of the present application, the core panel 2 is a lightweight concrete panel, which is cast by lightweight concrete. The lightweight concrete has the characteristics of light weight, high strength, thermal insulation, shock resistance and anti-seepage. Compared with ordinary concrete of the same grade, the weight can be reduced by more than 20% to 30%. The core panel 2 made of lightweight concrete has sufficient strength and can provide reliable and stable support for the wall panel body 1. In other embodiments of the present application, the core panel 2 may also be a foam insulation board, which is currently the most ideal insulation material for wall insulation and wall insulation fire isolation zone. The core panel 2 composed of foam insulation board has the advantages of low thermal conductivity, good insulation effect, non-combustibility, waterproofness, high strength, and environmental protection. It can reduce the weight of the board while providing reliable and stable support for the wall panel body 1.

[0038] A plurality of mutually parallel pipe holes 21 are provided inside the core plate 2. In the embodiment 1 of the present application, the number of the pipe holes 21 is 10, and the pipe holes 21 are staggered and spaced apart, and the pipe holes 21 penetrate the core plate 2. In other embodiments of the present application, the number of the pipe holes 21 can be increased or decreased according to actual conditions, as long as enough pipe holes 21 are reserved.

[0039] Reference Figure 2 , the support plate 3 surrounds the core plate 2, and the support plates 3 on each side of the core plate 2 along its own height direction are formed by multiple support strips 31 laid in an interlaced manner, and a gap of 10mm-15mm is left between the support strips 31 laid on the same side of the core plate 2. It is stipulated that the two long sides in the vertical direction of the height of the core plate 2 are the upper and lower sides of the core plate 2, and the two wide sides in the vertical direction of the height of the core plate 2 are the left and right sides of the core plate 2. In other embodiments of the present application, since the thickness of the wallboard is much smaller than its own length, the support plates 3 on the left and right sides of the core plate 2 can be formed by a whole support strip 31, and the support plates 3 on the upper and lower sides of the core plate 2 are still formed by multiple support strips 31 laid in an interlaced manner. The support strips 31 can be made of recycled wood boards, so that the support strips 31 have the advantages of environmental protection while having sufficient strength. At the same time, the wood boards can also effectively increase the toughness of the wallboards, and can also enhance the nail holding force when screws need to be installed in subsequent construction.

[0040] There is a gap between each two adjacent support plates 3 around the core plate 2, and there is also a gap between the support plate 3 and the core plate 2, and the gap between the support plate 3 and the core plate 2 is filled with a magnesium oxychloride layer 4, and the thickness of the magnesium oxychloride layer 4 filled between the support plate 3 and the core plate 2 is maintained at more than 5mm, and the magnesium oxychloride layer 4 is formed by pouring magnesium oxychloride cement. Magnesium oxychloride cement combines many advantages such as light weight, fire resistance, early strength, frost resistance, and resistance to salt and alkali corrosion. It also has the characteristics of air hardening and can harden in the air, so that it has good air stability. In other embodiments of the present application, magnesium oxychloride cement can also be replaced by high-strength mortar, which can also improve the overall strength of the wallboard body 1.

[0041] After the magnesium oxychloride layer 4 between the support plate 3 and the core plate 2 is poured, the magnesium oxychloride layer 4 is poured again on the outside of the support plate 3. At the same time, a layer of mesh cloth 9 is laid on the outside of the support plate 3 located on the upper and lower sides of the core plate 2, and the mesh cloth 9 covers all the support strips 31 spliced ​​into the support plate 3. When making the wallboard, the mesh cloth 9 is first laid outside the support strips 31 spliced ​​with staggered seams, and then the magnesium oxychloride layer 4 is poured on the surface of the mesh cloth 9. The thickness of the magnesium oxychloride layer 4 on the outside of the support plate 3 is also maintained at more than 5mm. The laid mesh cloth 9 can effectively prevent cracking between the staggered support strips 31, thereby improving the overall strength of the wallboard. At this point, the magnesium oxychloride layer 4 is filled in the gaps between all the plate components, and the magnesium oxychloride layer 4 also forms an outer wrapping for all the plate components. The high strength of the magnesium oxychloride cement can be used to improve the overall strength of the wallboard, so that the wallboard can be used as an exterior wallboard, an interior partition wall and a floor slab at the same time, thereby improving the use function of the wallboard.

[0042] Reference Figure 1 and Figure 2 A groove 11 is provided on the outermost magnesium oxychloride layer 4 on the left and right sides of the core plate 2. The groove 11 is correspondingly provided at the midline position of the left and right support plates 3 on the core plate 2, and the groove 11 penetrates the outermost magnesium oxychloride layer 4 along the height direction of the core plate 2. The opening of the groove 11 is semicircular. In other embodiments of the present application, the opening of the groove 11 can also be semi-elliptical or trapezoidal, which can be provided according to the actual construction situation.

[0043] The thickness of the outermost magnesium oxychloride layer 4 located on the left and right sides of the core board 2 gradually becomes thinner from the middle to the sides, forming a hypotenuse 12 symmetrical with respect to the midline of the left and right sides of the core board 2. At the same time, a tongue 13 is provided on the outermost magnesium oxychloride layer 4 corresponding to the upper and lower sides of the core board 2, and the tongue 13 is provided at the two edges of the outermost magnesium oxychloride layer 4 and is concave.

[0044] The implementation principle of a multifunctional wall panel in Example 1 of the present application is as follows: a core board 2, a support board 3 and a magnesium oxychloride layer 4 formed by pouring together form a wall panel body 1, and the magnesium oxychloride layer 4 can effectively improve the strength of the wall panel body 1, and integrates many advantages such as light weight, fire resistance, early strength, frost resistance, and resistance to salt and alkali corrosion, so that the wall panel body 1 can be used as an exterior wall panel, interior partition wall or floor slab at the same time; the core board 2 is made of lightweight and heat-insulating material, which can reduce the weight of the board while providing reliable and stable support for the wall panel body 1; the support board 3 can effectively increase the toughness of the wall panel, and can also enhance the nail holding force when screws need to be installed during subsequent construction.

[0045] Embodiment 2:

[0046] Embodiment 2 of the present application discloses a multifunctional wall panel connection structure for connecting the multifunctional wall panel in embodiment 1 with other components. Figure 3 The multifunctional wall panel connection structure also includes a sound insulation material 5 and an adhesive material 6. When two wall panel bodies 1 are spliced, the grooves 11 of the two wall panel bodies 1 are first aligned, and the sound insulation material 5 is filled in one of the grooves 11, and then the two wall panel bodies 1 are brought close to each other so that the sound insulation material 5 fills the space formed by the two grooves 11. The sound insulation material 5 can be a sound absorbing strip or foam. The sound insulation material 5 can fill the connection gap between the wall panel bodies 1, which can effectively reduce the sound transmission through the seam and the smoke transmission in case of fire.

[0047] Two outward openings are formed between the inclined surfaces at the joint surfaces of the two wall panel bodies 1, and the openings gradually expand outward, and adhesive material 6 is filled into the openings. The adhesive material 6 can be a special structural adhesive. The adhesive material 6 fills the gaps in the wall panel bodies 1. The adhesive material 6 will also fill the space formed by the groove 11, so that the two adjacent wall panel bodies 1 can be tightly combined together.

[0048] Two adjacent tongues and grooves 13 of adjacent wall panel bodies 1 at the butt joint surface form a concave space, in which a layer of mesh cloth 9 is laid, the mesh cloth 9 is closely attached to the surface of the wall panel body 1, and the concave space formed by the tongue and groove 13 is also filled with adhesive material 6, the laid mesh cloth 9 can effectively improve the connection stability between the wall panel body 1 and other components, and reduce cracking. Finally, a layer of gypsum putty can be applied outside the adhesive material 6, so that the two wall panel bodies 1 form a whole.

[0049] Reference Figure 4The wall panel body 1 can also be arranged between the upper and lower floors 8. In this case, the two sides of the wall panel body 1 with the groove 11 are placed vertically, so that the two sides of the wall panel body 1 with the groove 11 are connected to the floor 8. Similarly, the sound insulation material 5 can be filled in the groove 11, and the adhesive material 6 can be used to fill the gap between the wall panel body 1 and the floor 8, so that the wall panel body 1 and the floor 8 are bonded. When connecting, the wall panel body 1 at the top can be bonded to the upper floor 8 with the adhesive material 6, and the wall panel body 1 at the bottom can be fixed to the lower floor 8 with fine stone concrete 7.
