Technical Field
[0001] This application relates to the technical field of building walls, and in particular to a composite wall panel structure with waterproof and heat-insulating effects. Background Technology
[0002] With the continuous development of modern architecture, people have higher requirements for the functionality of buildings. Traditional building walls are divided into two categories: on-site masonry and precast walls, both of which are widely used in building construction. After the exterior walls of a building are completed, in order to improve the thermal insulation of the exterior walls, it is usually necessary to add an insulation layer on the outside of the walls to meet the requirement of improving the wall's thermal insulation performance.
[0003] However, during rainy seasons with high humidity, insulation boards can deform, and rainwater can easily seep into the insulation layer, causing peeling of the building's exterior walls, creating certain safety hazards. It also affects the insulation and waterproofing of the building's exterior walls, impacting the normal use of the building structure. Utility Model Content
[0004] To improve the thermal insulation and moisture-proof performance of wall panels, this application provides a composite wall panel structure with waterproof and thermal insulation effects.
[0005] The composite wall panel structure with waterproof and heat-insulating effects provided in this application adopts the following technical solution:
[0006] A composite wall panel structure with waterproof and heat-insulating effects includes a mounting steel frame, a composite wall panel, and an exterior decorative panel. The mounting steel frame is vertically arranged, and the composite wall panel is connected to one side of the mounting steel frame. Several exterior decorative panels are connected to the side of the composite wall panel away from the mounting steel frame. The composite wall panel includes a rainproof curtain wall with a polyurethane insulation board disposed on one side of the polyurethane insulation board, and the rainproof curtain wall is disposed on the side of the polyurethane insulation board away from the mounting steel frame.
[0007] By adopting the above technical solution, a rainproof curtain wall is installed on one side of the polyurethane insulation board, which helps to improve the waterproof performance of the wall. The exterior decorative panel is placed on the outermost side, which protects the wall and reduces the possibility of damage to the polyurethane insulation board and the rainproof curtain wall during use. Through the cooperation of the steel frame, composite wall panels and exterior decorative panels, waterproof and thermal insulation of the wall are achieved, which improves the thermal insulation and moisture-proof performance of the wall panels.
[0008] Optionally, a layer of magnesium oxysulfate board is provided on both opposite sides of the polyurethane insulation board, and the magnesium oxysulfate board away from the mounting steel frame is connected to the rainproof curtain wall.
[0009] By adopting the above technical solution, magnesium oxysulfate board exhibits excellent fireproof, heat-insulating, waterproof, and moisture-proof properties. The magnesium oxysulfate board has a layer on both sides of the polyurethane insulation board, which helps to improve the waterproof and heat-insulating performance of the composite wall panel.
[0010] Optionally, a waterproof and breathable cloth is provided between the composite wall panel and the rainproof curtain wall.
[0011] By adopting the above technical solution, the installation of waterproof and breathable cloth ensures the waterproof performance of the composite wall panel while allowing moisture inside the wall panel to escape.
[0012] Optionally, an aluminum strip is provided between two adjacent exterior panels. On the two opposite sides of the aluminum strip away from the composite wall panel, a limiting plate is provided in the vertical direction. The exterior panel includes a surface layer and two bent layers perpendicularly arranged on both sides of the width direction of the surface layer. The two bent layers and the surface layer together form a rainproof cavity facing the composite wall panel. The rainproof curtain wall is disposed in the rainproof cavity. The side of the surface layer away from the composite wall panel abuts against the side of the limiting plate close to the composite wall panel.
[0013] By adopting the above technical solution, before connecting the outer decorative panel, the mounting aluminum strip is connected to the composite wall panel, and the outer decorative panel is inserted between the two corresponding mounting aluminum strips. The limiting plate limits the two sides of the outer decorative panel, thus realizing the detachable connection between the outer decorative panel and the composite wall panel.
[0014] Optionally, the mounting aluminum strip is hollow, and sliding openings are provided vertically on the two sides of the mounting aluminum strip adjacent to the composite wall panel. The two limiting plates correspond one-to-one with the two sliding openings and are slidably connected. An abutting elliptical block is rotatably disposed in the inner cavity of the mounting aluminum strip. The two limiting plates have corresponding snap-fit grooves on their adjacent sides. An elastic element connects the two limiting plates. The abutting elliptical block is correspondingly disposed with the snap-fit groove. In the natural state, the limiting plate abuts against the abutting elliptical block under the action of the elastic element. When the end of the abutting elliptical block in the length direction is snapped into the snap-fit groove, the edge of the limiting plate extends out of the mounting aluminum strip.
[0015] By adopting the above technical solution, when connecting the exterior trim panel, the panel is placed between two adjacent corresponding mounting aluminum strips, and rotated to abut the elliptical block until both ends of the elliptical block are embedded in the corresponding locking grooves of the side limiting plates. The edges of the limiting plates extend out of the mounting aluminum strips and limit the exterior trim panel. When it is necessary to remove the exterior trim panel, the elliptical block is rotated in the opposite direction, and the two limiting plates retract the mounting aluminum strips under the action of the elastic element, realizing the quick installation and removal of the exterior trim panel.
[0016] Optionally, the rainproof curtain wall includes a supporting partition and a rainproof panel. The rainproof panel is disposed between the two bending layers on one side near the composite wall panel. The rainproof panel is arranged parallel to the finishing layer. The supporting partition is horizontally disposed at the top of the rainproof inner cavity. The supporting partition has several water-permeable holes.
[0017] By adopting the above technical solution, the supporting partition is set in the rainproof inner cavity and internally supported. The water in the rainproof inner cavity flows downward and is discharged through the water-permeable holes, reducing the possibility of water accumulation in the wall panel.
[0018] Optionally, a number of support columns connect the rainproof panel and the finishing layer.
[0019] By adopting the above technical solution, the support column is set between the rainproof panel and the finishing layer, which reduces the possibility of deformation of the finishing layer during use.
[0020] Optionally, a water-guiding sloping plate is inclinedly connected between the rainproof panel and the decorative layer, a drain outlet is provided on the decorative layer, and a drain plate for sealing the drain outlet is provided on the decorative layer, with the lower side of the water-guiding sloping plate corresponding to the bottom end of the drain outlet.
[0021] By adopting the above technical solution, when it is necessary to clean the water in the rainproof inner cavity, the drain plate can be removed, and the water will flow out of the rainproof inner cavity through the drain outlet along the water guide plate.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. By installing steel frames, composite wall panels, and exterior decorative panels in combination, waterproofing and thermal insulation of the wall are achieved, which improves the thermal insulation and moisture-proof performance of the wall panels;
[0024] 2. The installation of aluminum strips enables a detachable connection between the exterior decorative panel and the composite wall panel;

Detailed Implementation
[0033] The following is in conjunction with the appendix Figure 1-6 This application will be further described in detail below. Embodiments of this application provide a composite wall panel structure with waterproof and thermal insulation properties, which improves the thermal insulation and moisture-proof performance of the wall panel.
[0034] Example 1
[0035] Reference Figure 1 and Figure 2 A composite wall panel structure with waterproof and thermal insulation properties includes a steel frame 1, composite wall panels 2, exterior decorative panels 3, a rainproof curtain wall, and aluminum strips 4. The steel frame 1 is vertically arranged, and the composite wall panels 2 are vertically connected to the outward-facing side of the steel frame 1. The composite wall panel 2 includes a polyurethane insulation board 21, a magnesium oxysulfate board 22, and a waterproof and breathable cloth 23. A layer of magnesium oxysulfate board 22 is connected to both sides of the polyurethane insulation board 21, and the waterproof and breathable cloth 23 is located on the side of the magnesium oxysulfate board 22 away from the steel frame 1.
[0036] Reference Figure 1 and Figure 2Several exterior decorative panels 3 are vertically arranged on the side of the composite wall panel 2 away from the mounting steel frame 1, and an aluminum strip 4 is installed between two adjacent exterior decorative panels 3. Each exterior decorative panel 3 includes a connecting edge 31, a decorative layer 32, and a bending layer 33. Two bending layers 33 are vertically connected to the decorative layer 32 on the side closest to the composite wall panel 2, and the two bending layers 33 are respectively located on both sides of the width direction of the decorative layer 32. One connecting edge 31 is vertically connected to each bending layer 33 on the side away from the decorative layer 32, and the two connecting edges 31 are parallel to the decorative layer 32. The decorative layer 32 and the two bending layers 33 together form a rainproof inner cavity, and one rainproof curtain wall is installed in each rainproof inner cavity.
[0037] Reference Figure 3 The aluminum strip 4 is hollow, and two staggered, vertically arranged supporting inclined plates 5 are installed within it. A connecting T-shaped strip 6 is vertically arranged on the side of the aluminum strip 4 closest to the composite wall panel 2, and the connecting T-shaped strip 6 is connected to the composite wall panel 2 by countersunk bolts. The connecting edge 31 is inserted into the groove corresponding to the connecting T-shaped strip 6. A limiting plate 7 is vertically arranged on both sides of the width direction of the aluminum strip 4, located on the side of the aluminum strip 4 away from the composite wall panel 2 and parallel to the composite wall panel 2. The limiting plate 7 is fitted against the side of the finishing layer 32 away from the composite wall panel 2.
[0038] Reference Figure 2 The rainproof curtain wall includes a supporting partition 8, a rainproof panel 24, and supporting columns 10. The supporting partition 8 is horizontally installed at the top of the outer cladding panel 3, sealing the top of the rainproof inner cavity. Several water-permeable holes 81 are provided on the supporting partition 8. The rainproof panel 24 is vertically installed on the side of the rainproof inner cavity near the composite wall panel 2. Several supporting columns 10 connect the rainproof panel 24 and the cladding layer 32.
[0039] Reference Figure 1 and Figure 2 Both sides of the polyurethane insulation board 21 are provided with magnesium oxysulfate boards 22. Magnesium oxysulfate boards 22, as an air-hardening cementitious material, have excellent fireproof, heat-insulating, waterproof, and moisture-proof properties. A waterproof and breathable cloth 23 is placed on the side of the magnesium oxysulfate board 22 away from the mounting steel frame 1, facilitating moisture expulsion from the interior while ensuring the waterproof performance of the composite wall panel 2. After the composite wall panel 2 is installed, the mounting aluminum strips 4 are connected to the surface of the composite wall panel 2 away from the mounting steel frame 1 using countersunk bolts. The outer decorative panel 3 is inserted between two corresponding mounting aluminum strips 4. A gap is left between the decorative layer 32 and the rainproof panel 24. When moisture exists in the wall, the moisture flows downwards through the rainproof cavity and is discharged, reducing the possibility of moisture remaining inside the wall. The support columns 10 and support partitions 8 help improve the structural strength of the outer decorative panel 3 and reduce the possibility of deformation of the outer decorative panel 3 during use.
[0040] The implementation principle of the composite wall panel structure with waterproof and heat-insulating effects in Embodiment 1 of this application is as follows: Magnesium oxysulfate boards 22 are provided on both opposite sides of the polyurethane insulation board 21, improving the fireproof, heat-insulating, waterproof, and moisture-proof performance of the composite wall panel 2. A waterproof and breathable cloth 23 is placed on the side of the magnesium oxysulfate board 22 away from the installation steel frame 1, facilitating the expulsion of moisture from the interior while ensuring the waterproof performance of the composite wall panel 2. A gap is left between the finishing layer 32 and the rainproof panel 24, allowing moisture to flow downwards and drain out through the rainproof cavity when it exists in the wall, reducing the possibility of moisture remaining inside the wall.
[0041] Example 2
[0042] Reference Figure 4 and Figure 5 The difference between Embodiment 2 and Embodiment 1 is that each of the opposite sides of the mounting aluminum strip 4 has a sliding opening 41 along the vertical direction. The two sliding openings 41 correspond one-to-one with the two limiting plates 7 and are slidably connected. An anti-detachment strip 11 is vertically installed at the end of the limiting plate 7 inside the mounting aluminum strip 4. A rotating shaft 12 is rotatably installed on the side of the mounting aluminum strip 4 away from the composite wall panel 2. A rotating block 13 is connected to the end of the rotating shaft 12 outside the mounting aluminum strip 4, and an abutting elliptical block 14 is installed at the end of the rotating shaft 12 inside the mounting aluminum strip 4. A snap-fit groove 71 is provided on the side of the two limiting plates 7 that is close to each other, and the two snap-fit grooves 71 are positioned corresponding to the abutting elliptical block 14. Several connecting springs 15 are connected to the side of the two limiting plates 7 that is close to each other. The edges of the two limiting plates 7 abut against the abutting elliptical block 14 under the action of the connecting springs 15. When the abutting elliptical block 14 rotates to a horizontal state, the edges of the two limiting plates 7 extend out of the mounting aluminum strip 4 under its abutting action.
[0043] Reference Figure 6 An inclined water-guiding plate 16 is connected to the rainproof inner cavity, and the water-guiding plate 16 is located below several support columns 10. A drain outlet 17 is provided on the finishing layer 32, and a drain plate 9 is detachably connected to the drain outlet 17. The lower side of the water-guiding plate 16 is correspondingly set to the bottom end of the drain outlet 17.
[0044] The implementation principle of the composite wall panel structure with waterproof and heat-insulating effect in Embodiment 2 of this application is as follows: When connecting the mounting aluminum strip 4 and the outer decorative panel 3, the outer decorative panel 3 is placed between two corresponding mounting aluminum strips 4. The rotating block 13 is turned, and the abutting elliptical block 14 rotates to a horizontal state and is locked in the locking groove 71. The connecting spring 15 extends and accumulates elastic potential energy. Under the action of the abutting elliptical block 14, the two limiting plates 7 extend out of the mounting aluminum strip 4 and limit the connection of the outer decorative panel 3, realizing a quick and detachable connection between the mounting aluminum strip 4 and the outer decorative panel 3. When it is necessary to remove the outer decorative panel 3, the rotating block 13 is turned, and the edge of the limiting plate 7 retracts into the mounting aluminum strip 4, releasing the limitation on the outer decorative panel 3.
[0045] When water accumulates in the rainproof cavity, the drainage plate 9 is removed from the drainage outlet 17, and the water in the rainproof cavity flows out along the water guide plate 16, thus cleaning up the water.
[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
