Description

Technical Field

[0001] The invention relates to the technical field of exterior wall insulation, in particular to a building exterior wall decorative insulation device. Background Art

[0002] External wall decoration and insulation technology achieves insulation and decoration functions by adding one or more layers of insulation materials on the surface of the building's external wall, and then adding a decorative layer on the outside. Its main functions include thermal insulation, decoration and wall protection.

[0003] After searching, the Chinese patent with patent number CN114000599B includes a mortar leveling layer, a thermal insulation adhesive layer, a thermal insulation component and a decorative layer which are connected to the exterior wall of the building from the inside to the outside in sequence. The thermal insulation component is bonded to the mortar leveling layer through the thermal insulation adhesive layer, and the decorative layer is bonded and fixed to the thermal insulation component; the thermal insulation component includes two vertically arranged support rods, a placement piece arranged between the two support rods, and a number of thermal insulation boards fixed on the placement piece, the support rods are respectively located at both ends of the exterior wall of the building along the length direction, and the support rods are pressed against and bonded and fixed to the thermal insulation adhesive layer, and an anti-detachment block is also arranged between the support rod and the thermal insulation adhesive layer to reduce the risk of the support rod detaching from the exterior wall of the building.

[0004] In this case, connecting parts are used to prevent the insulation layer from being directly installed on the exterior wall of the building, thereby reducing the impact of the deformation of the exterior wall of the building on the insulation layer, and thereby reducing the risk of the insulation material falling off the exterior wall of the building; anti-detachment blocks are used to enhance the connection area and strength between the support rod and the insulation adhesive layer, thereby reducing the risk of the insulation board falling off the exterior wall of the building.

[0005] However, although the structural coordination between the fixing strip and the cross bar in this case can reduce the probability of deformation of the cross bar or the support bar, it is easy to cause the fixing strip to dislocate when the deformation of the building's exterior wall is large, thereby causing its buffering effect to fail; on the other hand, as the device is used for a longer period of time, the conical clamping relationship between the anti-slip rod and the cross bar is gradually strengthened, resulting in an increase in the connection strength between the cross bar and the insulation board, making it difficult for the device to achieve the expected shock-absorbing effect.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0031] See also Figures 1 to 9 The present invention provides a technical solution: a building exterior wall decoration insulation device, comprising a buffer component for absorbing the deformation stress of the exterior wall panel 1 and a heat insulation component for heat insulating the exterior wall panel 1, characterized in that: the buffer component is installed between the exterior wall panels 1 and is fixedly connected to the exterior wall panels 1, and the buffer component is fixedly connected to the heat insulation component;

[0032] The exterior wall panels 1 are provided in multiple groups and the number of each group is fixed at four. Every two exterior wall panels 1 are transmission-connected via a buffer assembly and are arranged at intervals. Four corners of the outer contour of the exterior wall panels 1 close to the insulation assembly are provided with mounting holes 11.

[0033] In the present device, the exterior wall panel 1 is a plate-type structure covering the exterior wall of the building, and its size and number of uses are determined according to the actual scenario. The buffer component is fixedly connected to the exterior wall panel 1 through the mounting hole 11 and satisfies the correspondence between the quantity and position of the exterior wall panel 1 and the buffer component. The structural characteristics of the buffer component can absorb the deformation of the exterior wall panel 1 caused by temperature changes, foundation settlement and the like to the greatest extent, thereby effectively dispersing and absorbing stress and preventing the structural cracking and damage of the exterior wall panel 1 and the insulation component; the insulation component reduces the heat loss of the building while balancing the temperature distribution at various positions, thereby further improving the structural life of the insulation component; the fixing mechanism further improves the thermal insulation effect of the insulation component while providing a limiting connection for the guide component; the guide component prevents the direct erosion of the insulation component structure by the external environment while improving the appearance of the building, and guides the erosion angle of the environment such as wind and rain to further extend the service life of the building. Example

[0034] See also Figure 3-Figure 4 , this embodiment further explains the first embodiment, the buffer component is provided with multiple groups and each group includes four centrally symmetrically distributed positioning plates 2, the four positioning plates 2 are respectively located around the outer contour of the side of the exterior wall panel 1 away from the wall body, the center of the four positioning plates 2 away from the exterior wall panel 1 is penetrated and threadedly connected with a fixing bolt 21, the fixing bolt 21 is threadedly connected to the mounting hole 11, and a filling pad 22 is fixedly connected to the opposite surface of each group of the positioning plates 2, and the interior of the filling pad 22 is penetrated and fixedly connected with a buffer plate 23, both ends of the buffer plate 23 are fixed to the outer contour of the positioning plate 2, and an arc plate 24 is fixedly connected to the outer contour of the side of the exterior wall panel 1 of each group of the positioning plates 2, and the relative positioning plates 2 between different groups are connected by transmission through the arc plate 24, and each of the arc plates 24 is penetrated and fixedly connected at the position on the vertical center line with two positioning bolts 25 symmetrically distributed up and down.

[0035] Both ends of the filling pad 22 are chamfered at an angle of 45 degrees, and the filling pad 22 is made of elastic material.

[0036] The buffer plate 23 is a metal spring structure and is processed by a multi-layer bending process. The buffer plate 23 is made of stainless steel material. The bending angle of the arc plate 24 is ninety degrees.

[0037] It can be seen from Example 2 that since the buffer components are arranged around each exterior wall panel 1, the distribution of the buffer components on the exterior wall of the building is a grid-type distribution that is staggered horizontally and vertically. When the exterior wall panel 1 expands or contracts, since the exterior wall panel 1 and the positioning plate 2 are fixedly connected by the fixing bolts 21, that is, the fixing bolts 21 change position synchronously with the deformation of the exterior wall panel 1. At this time, the relative distance between each group of fixing bolts 21 changes and causes the filling pad 22 and the buffer plate 23 to be stretched or compressed. Since the filling pad 22 is made of elastic material, such as polyurethane foam, silicone sealant, etc., it can effectively ensure the structural life of the filling pad 22 under long-term use. The buffer plate 23 is a metal spring structure and is processed by a multi-layer bending process. The structure of the buffer plate 23 can effectively absorb the vertical and horizontal deformation stresses between the exterior wall panels 1, thereby avoiding structural damage or cracking of the exterior wall panel 1 due to deformation.

[0038] At the same time, when the relative distance between the fixing bolts 21 changes, the arc plate 24 deforms synchronously. At this time, due to the bending setting of the structural characteristics of the arc plate 24, the two ends of the arc plate 24 will generate a large reaction force and bending stress, thereby offsetting a part of the deformation degree of the exterior wall panel 1. In this case, the stress at the two ends of the arc plate 24 is larger and the stress in the middle part is smaller. This is because the positioning bolt 25 is fixedly connected to the vertical center line of the arc plate 24 and the positioning bolt 25 is limitedly slidably connected to the insulation board 3, that is, when radial deformation occurs in the middle of the arc plate 24, the positioning bolt 25 expands and contracts synchronously and does not affect the insulation component, thereby minimizing the structural influence of the deformation stress of the exterior wall panel 1 on the insulation component.

[0039] On the other hand, since the bending angle of the arc plate 24 is 90 degrees, that is, the arc plate 24 can effectively absorb the deformation stress when the exterior wall panel 1 expands and contracts, so that the device meets the purpose of adapting to changes in ambient temperature during long-term use. In addition, because the buffer plate 23 is made of stainless steel, stainless steel is a poor conductor of heat, and its own thermal conductivity is low, it effectively reduces the probability that the buffer plate 23 affects the heat transfer path of the device and causes the buffer plate 23 itself to deform. At the same time, the 45-degree chamfer design at both ends of the filling pad 22 allows each group of buffer components to be completely assembled during installation, thereby minimizing the gap between the buffer components, further isolating the exterior wall panel 1 from the external environment, thereby effectively preventing direct contact between the exterior wall panel 1 and the external environment.

[0040] It should be noted that with the long-term use of the device, the exterior wall panel 1 will inevitably be corroded by external factors and cause structural damage. At this time, since the exterior wall panel 1 is fixedly connected to the positioning plate 2 on all sides and only by one fixing bolt 21, that is, when the outer surface of the exterior wall panel 1 is corroded, the positioning plate 2 may be deflected along with the fixing bolt 21 to adapt to the outer contour of the corroded exterior wall panel 1, and each arc plate 24 is fixedly connected with two positioning bolts 25. The two positioning bolts 25 can effectively prevent the arc plate 24 from synchronously deflecting with the positioning plate 2, thereby further reducing the stress influence of the exterior wall panel 1 on the insulation component. At this time, the buffer component can still work normally, thereby further improving the service life of the device. Example

[0041] See also Figure 5-Figure 6 The present embodiment further explains the second embodiment, wherein the heat-insulating assembly comprises a heat-insulating plate 3, and a plurality of positioning holes 31 are opened at the position of the center line of the outer contour of the heat-insulating plate 3, and the positioning holes 31 correspond to the positions of the positioning bolts 25 and are limitedly slidably connected. Four heat-conducting rings 32 are fixedly connected to the outer contour of the heat-insulating plate 3 on the side close to the positioning plate 2, and each heat-conducting ring 32 corresponds to the position at the center of the exterior wall panel 1. A heat-conducting shaft 33 is penetrated and limitedly slidably connected to each side of the heat-conducting ring 32 close to the positioning plate 2, and each heat-conducting shaft 33 is fixedly connected to a limiting plate 34 on the outer contour of the inner side of the heat-conducting ring 32, and a connecting spring 35 is fixedly connected between the outer contour of each limiting plate 34 away from the outer wall panel 1 and the inner contour of the heat-conducting ring 32, and a fixing mechanism for enhancing the heat insulation effect of the heat-insulating assembly is provided on the outer contour of the heat-insulating plate 3 on the side away from the positioning plate 2.

[0042] The heat-conducting ring 32 and the heat-conducting shaft 33 are both made of copper alloy material, the limiting plate 34 and the connecting spring 35 are both made of stainless steel alloy material, and each of the connecting springs 35 is in a compressed state.

[0043] It can be seen from Example 2 that the filling pad 22, the buffer plate 23 and the arc plate 24 can effectively absorb the lateral and vertical stresses generated when the exterior wall panel 1 is deformed, and the arc plate 24 and the positioning bolt 25 can effectively absorb the radial stress generated when the exterior wall panel 1 is deformed, that is, the overall relative position of the insulation board 3 is not affected by the deformation of the exterior wall panel 1. At this time, the deformation stress of the exterior wall panel 1 is absorbed by the buffer component and reaches the insulation board 3. It reaches the minimum, thereby effectively protecting the structural effect of the insulation board 3.

[0044] On the other hand, since the connecting spring 35 is in a compressed state, the limiting plate 34 is held against the inner contour of the heat-conducting ring 32 on the side close to the heat-conducting shaft 33 and the extension of the heat-conducting shaft 33 reaches the maximum. At this time, the heat-conducting shaft 33 is in contact with the outer wall panel 1. Along with the radial deformation of the outer wall panel 1, the compression degree of the connecting spring 35 changes synchronously. The greater the expansion degree of the outer wall panel 1, the greater the compression degree of the connecting spring 35, that is, the smaller the extension degree of the heat-conducting shaft 33. Because the heat-conducting ring 32 and the heat-conducting shaft 33 are both made of copper alloy, and the limiting plate 34 and the connecting spring are made of copper alloy, the limiting plate 34 and the connecting spring are made of copper alloy. 35 are all made of stainless steel alloy. Copper alloy is a good conductor of heat, and its own thermal conductivity is significantly higher than that of stainless steel alloy. At this time, the heat transfer path between the exterior wall panel 1 and the insulation board 3 is exterior wall panel 1 → heat conduction shaft 33 → heat conduction ring 32 → insulation board 3. As the extension of the heat conduction shaft 33 decreases, the distance of the heat transfer path between the exterior wall panel 1 and the insulation board 3 decreases synchronously. As the expansion of the exterior wall panel 1 increases, the distance of the heat transfer path between the exterior wall panel 1 and the insulation board 3 decreases, and the heat conduction efficiency of the insulation board 3 to the exterior wall panel 1 increases. Therefore, when the exterior wall of the building is heated unevenly, the insulation assembly can effectively balance the temperature distribution at each position to further improve the structural life of the insulation board 3. Example

[0045] See also Figure 7-Figure 8 , this embodiment further explains Example 3, the fixing mechanism includes a reinforcing plate 4, the reinforcing plate 4 is fixedly connected to the outer contour of the insulation board 3 on the side away from the positioning plate 2, a spherical groove 41 is provided at the center of the outer contour of the reinforcing plate 4 on the side away from the insulation board 3, a square frame 42 is fixedly connected around the outer contour of the reinforcing plate 4 on the side away from the insulation board 3, four positioning springs 43 are fixedly connected to the outer contour of the reinforcing plate 4 on the side away from the insulation board 3, each of the positioning springs 43 is in a stretched state and corresponds to the position at the center of the exterior wall panel 1, and a guide component for reducing wind erosion is provided at the end of the positioning spring 4 away from the reinforcing plate 4.

[0046] The deflector assembly includes a decorative plate 5, which is fixedly connected to the end of the positioning spring 43 away from the reinforcing plate 4 and is slidably connected to the inner contour of the spherical groove 41. A cross frame 51 is fixedly connected to the center line position of the outer contour of the decorative plate 5 on one side close to the reinforcing plate 4. A hemispherical joint 52 is fixedly connected to the center of the outer contour of the side of the cross frame 5 away from the decorative plate 5. The hemispherical joint 52 is connected to the inner contour of the spherical groove 41 in a limited rotation manner on the outer contour of the side away from the cross frame 51. The peripheral wall of the outer contour of the decorative plate 5 on the side away from the reinforcing plate 4 adopts an arc chamfer design.

[0047] Furthermore, the insulation board 3 is structurally reinforced by the reinforcing plate 4 to further improve the thermal insulation effect of the insulation board 3. The positioning spring 43 limits the connection between the fixing mechanism and the guide assembly. The spherical groove 41 serves as a movable window of the guide assembly. The maximum deflection angle of the guide assembly is jointly limited by the square frame 42 and the positioning spring 43.

[0048] The decorative panel 5 in the guide assembly not only improves the appearance of the building, but also cooperates with the square frame 42 to prevent the external environment from directly eroding the structure of the insulation assembly, thereby further improving the service life of the device. When the wind flow directly erodes the decorative panel 5, under the action of wind force, the hemispherical joint 52 deflects at a corresponding direction angle in the spherical groove 41, and the square frame 42 in the corresponding direction is compressed while the square frame 42 in the opposite direction is stretched. At this time, the cross skeleton 51 and the hemispherical joint 52 deflect accordingly, thereby increasing the contact area between the decorative panel 5 and the wind flow. Increasing the contact angle can produce a greater guide effect, making the wind flow path smoother, reducing the generation of eddies and turbulence to reduce the erosion of the decorative panel by the wind, and further utilizing the deflection of the decorative panel 5 to achieve a guiding effect on the wind flow, thereby changing the erosion angle of the wind flow when the wind flow contacts the decorative panel 5 for the first time, so that the wind is guided away when it encounters the first decorative panel 5 to reduce the direct impact of the wind force on the subsequent decorative panels 5.

[0049] On the other hand, the arc-shaped chamfer adopted on the outer contour peripheral wall of the decorative plate 5 on the side facing away from the reinforcing plate 4 can effectively reduce wind resistance, improve the flow guidance effect, and reduce the generation of eddies and turbulence.
