Description

Technical Field

[0001] This utility model relates to the field of exterior wall decorative panels, and in particular to an installation and connection structure for thin-layer concrete exterior wall decorative panels. Background Technology

[0002] The exterior wall cladding connection structure is a specialized structure used to fix decorative cladding panels to the exterior walls of buildings, typically composed of metal components. Its core function is to securely install the decorative cladding panels onto the wall through mechanical connections and sealing design, while simultaneously meeting building requirements such as insulation, waterproofing, and earthquake resistance. Currently, the exterior wall cladding connection structure still has the following shortcomings:

[0003] (1) Insufficient installation complexity and compatibility

[0004] Traditional exterior wall cladding panel connection structures typically rely on multiple components for fixation. These components must be assembled step-by-step using bolts, welding, and other methods, resulting in a cumbersome construction process and requiring highly skilled workers. Furthermore, existing structures are poorly adaptable to variations in insulation layer thickness. When the insulation layer thickness is uneven or construction errors exist, it is difficult to achieve precise fitting using a single connector, often necessitating additional adjustments or the addition of shims, which affects installation efficiency and overall integrity.

[0005] (2) Insufficient stability

[0006] The contact surfaces between the mounting plate and the connectors are mostly smooth right-angle structures, which have weak resistance to horizontal displacement. Under the action of wind load or thermal expansion and contraction caused by temperature changes, the mounting plate is prone to loosening or even falling off.

[0007] Therefore, there is an urgent need in this field to design a novel installation and connection structure for thin-layer concrete exterior wall decorative panels. Utility Model Content

[0008] The purpose of this utility model is to provide an installation and connection structure for thin-layer concrete exterior wall decorative panels.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] A thin-layer concrete exterior wall decorative panel installation connection structure includes two upper connectors embedded in the top left and right sides of the back of the thin-layer concrete exterior wall decorative panel and two lower connectors embedded in the bottom left and right sides of the back of the thin-layer concrete exterior wall decorative panel. The two upper connectors and the two lower connectors are symmetrically distributed from left to right.

[0011] The upper connector is fixed to the fastener on the exterior wall of the building and / or the lower connector is fixed to the fastener.

[0012] Furthermore, the upper part of the upper connector is a Z-shaped plate, the lower end of the Z-shaped plate is connected to one side of the first circular connecting part, the other side of the first circular connecting part is connected to the upper end of the lower inclined plate, and the lower inclined plate is inclined toward the back of the thin-layer concrete exterior wall decorative panel.

[0013] The upper part of the lower connector is an upper inclined plate, which is inclined toward the back of the thin-layer concrete exterior wall decorative panel. The lower end of the upper inclined plate is connected to one side of the second circular connector, and the other side of the second circular connector is connected to the top inner side of the inverted U-shaped groove plate. The cross-section of the groove of the inverted U-shaped groove plate is a right trapezoid, and the side of the groove near the back of the thin-layer concrete exterior wall decorative panel is an inclined surface.

[0014] Alternatively, the middle part of the upper connector is bent horizontally; the top end of the upper connector extends outward horizontally to form a second horizontal extension, the bottom end of the upper connector extends outward horizontally to form a third horizontal extension, the inner end face of the horizontal bend in the middle of the upper connector forms an outer slope, and the lower surface of the horizontal bend in the middle of the upper connector forms an inner slope; two first through holes are symmetrically opened on the vertical surface below the horizontal bend in the upper connector, and the upper connector is fixedly connected to the steel mesh inside the thin-layer concrete exterior wall decorative panel by bolts passing through the first through holes.

[0015] The lower connector includes a second vertical plate. The outer side of the lower middle part of the second vertical plate extends horizontally to form a fourth horizontal extension. The end of the fourth horizontal extension extends downward to form a second vertical extension. The bottom end of the second vertical extension is flush with the bottom end of the second vertical plate. The inner side of the second vertical extension is a slope. The second vertical extension, the fourth horizontal extension, and the second vertical plate form a groove with a right-angled trapezoidal cross-section. Two second through holes are symmetrically opened in the part of the second vertical plate above the fourth horizontal extension. The lower connector is fixedly connected to the steel mesh by bolts passing through the second through holes.

[0016] Furthermore, the fastener includes a first upright plate, the lower end of the first upright plate extends outward in a horizontal direction to form a first horizontal extension, the middle part of the lower surface of the first horizontal extension protrudes downward to form a first protrusion, the end of the first horizontal extension extends downward to form a first vertical extension, the upper surface of the first horizontal extension protrudes upward near the end to form a second protrusion, and a bolt hole is provided in the center of the first upright plate.

[0017] The fastener is connected to the upper connector embedded in the thin-layer concrete exterior wall decorative panel through the groove between the first protrusion and the first vertical extension, and / or the fastener is connected to the lower connector embedded in the thin-layer concrete exterior wall decorative panel through the second protrusion.

[0018] Furthermore, both the outer and inner surfaces of the first upright plate are provided with anti-slip textures.

[0019] Furthermore, the connection between the first vertical plate and the first horizontal extension is thickened inward to form a sloped transition zone.

[0020] Furthermore, the inner side of the second protrusion is inclined, the outer side is vertical, and the cross-sectional shape of the second protrusion is a right trapezoid that is narrower at the top and wider at the bottom.

[0021] Furthermore, the inner and outer surfaces of the first protrusion are both vertical surfaces, the inner surface of the first vertical extension is a vertical surface, and the outer surface is an inclined surface; the heights of the first protrusion and the first vertical extension are equal.

[0022] Furthermore, the fastener is embedded in the fireproof insulation board, and the connecting bolt passes through the bolt hole and the EPS insulation board to fix the fastener to the wall.

[0023] Furthermore, when the fastener is connected to the upper connector, the upper part of the upper connector is inserted into the groove between the first protrusion and the first vertical extension of the fastener; when the fastener is connected to the lower connector, the second protrusion is inserted into the lower part of the lower connector.

[0024] Compared with the prior art, the outstanding advantages of this utility model are:

[0025] (1) Modular design and improved adaptability

[0026] The connecting structure for exterior wall decorative panels of this utility model, through the cooperation of the fixing part (the groove formed by the first protrusion and the first vertical extension) and the upper and lower connecting parts (the Z-shaped bend of the upper connecting part and the right-angled trapezoidal groove of the lower connecting part), can be compatible with various working conditions, simplify the installation process, and improve construction efficiency.

[0027] (2) Sealing and stability

[0028] The second protrusion of the fastener adopts a right-angled trapezoidal cross-section that is narrower at the top and wider at the bottom, forming multiple sealing surfaces after being inserted into the groove of the lower connector. Combined with the flexible filling layer composed of EPS insulation board and fireproof insulation board, it effectively blocks the path of moisture penetration while suppressing displacement of the cladding due to external forces, thus improving the waterproof stability and seismic performance of the structure. The fastener features an anti-slip textured design, increasing its friction and ensuring that the exterior wall decorative cladding does not slide after installation.

[0029] (3) Dual guarantee of durability and environmental protection

[0030] All fasteners and connectors are made of galvanized steel or stainless steel with anti-corrosion treatment, significantly extending the service life of the components in harsh environments such as humidity, heat, and salt spray. Furthermore, the modular design reduces on-site welding and cutting operations, minimizing material waste and aligning with the trend towards carbon-neutral green buildings.

The two upper connectors 2 and the two lower connectors 3 are symmetrically distributed from left to right.

[0052] The middle part of the upper connector 2 is bent horizontally; the top end of the upper connector 2 extends outward in the horizontal direction to form a second horizontal extension 21, the bottom end of the upper connector 2 extends outward in the horizontal direction to form a third horizontal extension 23, the outer end face of the horizontal bend in the middle of the upper connector 2 forms an outer inclined surface 22, and the lower surface of the horizontal bend in the middle of the upper connector 2 forms an inner inclined surface 24; two first through holes 25 are symmetrically opened on the vertical surface below the horizontal bend in the upper connector 2, and are fixedly connected to the steel mesh 9 inside the thin-layer concrete exterior wall decorative panel 8 by bolts passing through the first through holes 25.

[0053] The upper connector 2 has an elongated first grouting hole 26 located in the center of the facade below the horizontal bend. This hole is used to inject concrete when making thin-layer concrete exterior wall decorative panels to prevent the formation of cavities on the inner side of the upper connector 2.

[0054] The lower connector 3 includes a second vertical plate 31. The outer side of the lower middle part of the second vertical plate 31 extends horizontally to form a fourth horizontal extension 32. The end of the fourth horizontal extension 32 extends downward to form a second vertical extension 33. The bottom end of the second vertical extension 33 is flush with the bottom end of the second vertical plate 31. The inner side of the second vertical extension 33 is a slope. The second vertical extension 33, the fourth horizontal extension 32 and the second vertical plate 31 form a groove with a right trapezoidal cross section (narrower at the top and wider at the bottom). Two second through holes 34 are symmetrically opened in the part of the second vertical plate 31 above the fourth horizontal extension 32, and are fixedly connected to the steel mesh 9 by bolts passing through the second through holes 34.

[0055] The second vertical plate 31 of the lower connector 3 is also provided with an elongated second grouting hole 35 in the center, which is used to inject concrete when making thin-layer concrete exterior wall decorative panels, so as to prevent the formation of cavities on the inner side of the lower connector 3.

[0056] The upper connector 2 is connected to the fastener 1 fixed to the exterior wall of the building, and / or the lower connector 3 is connected to the fastener 1.

[0059] When the fastener 1 is only used to connect the lower thin-layer concrete exterior wall decorative panel 8, it is connected to the upper connector 2 embedded in the lower exterior wall decorative panel 8 through the groove between the first protrusion 13 and the first vertical extension 14.

[0060] When the fastener 1 is only used to connect the upper thin-layer concrete exterior wall decorative panel 8, it is connected to the lower connector 3 embedded in the upper exterior wall decorative panel 8 through the second protrusion 15.

[0061] Both the outer and inner surfaces of the first upright plate 11 are provided with anti-slip textures 16. The connection between the first upright plate 11 and the first horizontal extension 12 is thickened inward to form a sloping transition area. The inner side of the second protrusion 15 is sloping, and the outer side is vertical. The cross-sectional shape of the second protrusion 15 is a right-angled trapezoid that is narrower at the top and wider at the bottom. The inner and outer sides of the first protrusion 13 are both vertical. The inner side of the first vertical extension 14 is vertical, and the outer side is sloping (the cross-sectional shape is a right-angled trapezoid that is wider at the top and narrower at the bottom). The heights of the first protrusion 13 and the first vertical extension 14 are equal. The outer end of the first protrusion 13 is rounded.

[0062] The fastener 1 is embedded in the fireproof insulation board 6, and the connecting bolt 7 passes through the bolt hole 17 and the EPS insulation board 5 to fix the fastener 1 to the wall 4.

[0063] When the fixing member 1 is connected to the upper connecting member 2, the portion of the upper connecting member 2 located above the horizontal bend is inserted into the groove between the first protrusion 13 and the first vertical extension 14 of the fixing member 1. When the fixing member 1 is connected to the lower connecting member 3, the second protrusion 15 is inserted into the groove surrounded by the second vertical extension 33, the fourth horizontal extension 32, and the second upright plate 31.

[0064] Among them, the fastener 1 and the upper and lower connecting parts are all made of galvanized steel plate or stainless steel, and the surface is treated with anti-corrosion.

[0065] like Figure 10-12 As shown, the back side of the thin-layer concrete exterior wall decorative panel 8 has a different height than the front side, with the upper edge of the back side higher than the upper edge of the front side, and the lower edge of the back side higher than the lower edge of the front side. The steel mesh 9 is located between the back side and the front side.

[0066] Example 2

[0067] Compared with Embodiment 1, the only difference is that the shapes of the upper connector 2 and the lower connector 3 have been changed.

[0068] like Figures 13-15 As shown, the upper part of the upper connector is a Z-shaped plate 41. The lower end of the Z-shaped plate 41 is connected to one side of the first circular connecting part 42, and the other side of the first circular connecting part 42 is connected to the upper end of the lower inclined plate 43. The lower inclined plate 43 is inclined toward the back of the thin-layer concrete exterior wall decorative hanging panel 8.

[0069] The upper part of the lower connector is an upper inclined plate 51, which is inclined towards the back of the thin-layer concrete exterior wall decorative panel 8. The lower end of the upper inclined plate 51 is connected to one side of the second circular connecting part 52, and the other side of the second circular connecting part is connected to the top inner side of the inverted U-shaped groove plate 53. The cross-section of the groove of the inverted U-shaped groove plate 53 is a right trapezoid, and the side of the groove near the back of the thin-layer concrete exterior wall decorative panel 8 is an inclined surface.

[0070] When the fixing member 1 is connected to the upper connecting member, the upper and middle parts of the Z-shaped plate 41 in the upper connecting member are inserted into the groove between the first protrusion 13 and the first vertical extension 14 of the fixing member 1. When the fixing member 1 is connected to the lower connecting member, the second protrusion 15 is inserted into the groove of the inverted U-shaped groove plate 53.
