Description

Technical Field

[0001] The utility model relates to the technical field of exterior wall maintenance, and more specifically to the technical field of an exterior thermal insulation anti-falling device for buildings. Background Art

[0002] At present, the main method of building exterior wall insulation technology is to stick insulation boards and reinforce them with anchors. However, in actual applications, due to non-standard construction, material aging, and environmental factors (such as wind pressure, temperature changes, etc.), insulation boards often fall off, posing a great hidden danger to building safety. Based on actual project research, Liu Delin found that the existing insulation board anti-falling measures mainly include increasing the number of anchors and using high-performance adhesives (referenced literature: Liu Delin. Analysis of Construction Technology of Exterior Wall Insulation of House Construction Projects "Foshan Ceramics". 2024, 34 (09), pp. 144-146.). However, while these methods improve the stability of the insulation board, they also increase the construction cost and complexity, but the durability is not greatly improved.

[0003] In addition, there are a large number of patented technologies that use improved anchor nails or anti-falling anchor plate components for reinforcement, as follows:

[0004] Patent publication number CN116025075A discloses a method for anti-slip anchoring of insulation panels attached to the exterior walls of existing buildings. However, this patented method, which simply strengthens the anti-slip anchoring, has the following serious drawbacks: dense anti-slip anchors compress the insulation material, reducing the performance of the insulation layer and affecting the insulation effect; over time, the anchors may loosen and fall off, still posing a safety hazard; damage may occur to the exterior surface structure of the wall, affecting the overall stability and safety of the building; and the method requires a large number of anchors and other auxiliary materials, requiring a high labor cost, which increases the difficulty and cost of construction.

[0005] The patent with publication number CN118653585A discloses an anti-falling structure for ecological insulation boards. The patent adopts a bearing plate, a supporting bar and a connecting piece structure. The supporting groove formed between the supporting bar and the bearing plate for accommodating the ecological insulation board can reduce the probability of the ecological insulation board falling directly from the exterior wall. This technology mainly adopts partitioned glue injection to prevent the ecological insulation board from falling off. Although the existing technologies disclosed in the above patents and papers have alleviated the problem of insulation board falling off to a certain extent, they still have disadvantages such as potential safety hazards in the later stage, difficult construction, high cost, inconvenient maintenance, aging of adhesives, and loose anti-falling anchors. At the same time, the above technologies have all taken the issue of insulation into consideration. Utility Model Content

[0006] The purpose of this utility model is to solve the technical problems of poor insulation, aging adhesives, and loosening of anti-fall anchors in existing technologies. This utility model provides a building exterior insulation anti-fall device. It has the advantages of simple structure, convenient construction, and low cost. It can effectively prevent the fall of building facade insulation panels and also take into account the installation of fire isolation belts.

[0007] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0008] One aspect of the utility model provides an anti-falling device for exterior thermal insulation of a building, comprising a plurality of thermal insulation boards arranged at equal intervals on the exterior facade of the building, an anti-falling component for locking the ends of the two thermal insulation boards is arranged between two adjacent thermal insulation boards, and the anti-falling component comprises a connecting member for connecting the two adjacent thermal insulation boards together and a locking component with a self-locking function for locking the connecting member on the exterior facade of the building.

[0009] In one embodiment, the locking assembly includes a first locking assembly at one end of each insulation board and a second first locking assembly at the other end.

[0010] In one embodiment, the first locking assembly includes a fireproof isolation strip disposed between two adjacent insulation panels, two angle steel aluminum alloy keels disposed at the upper and lower ends of each fireproof isolation strip, a π-shaped cap plate, and two self-locking nails. Each angle steel aluminum alloy keel is stepped, and each angle steel aluminum alloy keel is partially embedded in the corresponding insulation panel. The π-shaped cap is disposed outside the fireproof isolation strip and the two angle steel aluminum alloy keels, and the two horizontal legs of the π-shaped cap extend into the interior of the two adjacent insulation panels respectively.

[0011] Each locking nail passes through a horizontal section of a supporting leg of a corresponding π-shaped cap, and the corresponding angle steel aluminum alloy keel is locked in a self-locking nail nut groove.

[0012] Specifically, insulation panels are installed on the exterior facades (exterior walls) of buildings to provide thermal insulation. Fire barriers prevent flames from spreading along the insulation panels in the event of a fire.

[0013] The self-locking nail nut groove is buried in the exterior wall of the building to accommodate the self-locking nails, which work together with the self-locking nails to fix the insulation board and the angle steel aluminum alloy keel.

[0014] The π-shaped cap plate plays the role of protecting the fire isolation zone; in addition, together with the upper and lower two angle steel aluminum alloy keels, it plays the role of limiting the insulation board.

[0015] In one embodiment, the inner sides of the two vertical sections of the π-shaped cap legs are provided with inner self-locking structures, and the outer sides of each angle steel aluminum alloy keel are provided with outer self-locking structures that cooperate with the corresponding inner self-locking structures.

[0016] Specifically, the angle steel aluminum alloy keel separates and limits the insulation panels, while also absorbing some of their weight. It also forms a locking frame with the protrusions above and below the π-shaped capping plate, limiting the panels' displacement. Finally, the cavity between the angle steel aluminum alloy keels allows for the installation of fireproof isolation strips. The angle steel aluminum alloy keel is pre-perforated at the junction with the π-shaped capping plate, where blind rivets are required, and at the insulation board, where self-locking rivets are required, to ensure securement.

[0017] In one embodiment, each angle steel aluminum alloy keel is provided with a portion for installing a blind-end aluminum rivet at the junction with the π-shaped cap plate.

[0018] In one embodiment, an aluminum alloy support bar is provided between the fireproof isolation strip and the corresponding π-shaped cap.

[0019] Specifically, the aluminum alloy stays serve to prevent deformation of the two angle steel aluminum alloy keels above and below the fire isolation.

[0021] Specifically, the outer side of the self-locking nail nut groove has its own thread and the inner side has a barb structure to prevent the self-locking nail from falling off.

[0022] In one embodiment, a highly elastic material glue is injected into the gap between the self-locking nail nut slot and the corresponding self-locking nail.

[0023] Specifically, the gap between the self-locking nail nut slot and the self-locking nail is injected with high elastic material glue (such as rubber, silicone, etc.) to absorb and disperse the stress changes of the insulation board caused by temperature changes, wind pressure and other factors.

[0024] In one embodiment, the first locking assembly includes a first locking nail passing through the insulation board.

[0025] Another aspect of the present invention provides a method for installing a building exterior thermal insulation anti-falling device, which is used to install the above-mentioned building exterior thermal insulation anti-falling device, comprising the following steps:

[0026] S1. Draw a diagram of the insulation board fixing components based on the structure and area of ​​the building's exterior facade.

[0027] S2. For new buildings, pre-buried self-locking screw nut slots according to the design drawings are sufficient; for existing buildings, the wall surface base should be treated first, then the wall should be drilled according to the drawings, and then the self-locking screw nut slots should be tapped;

[0028] S3. Temporary fixation of angle steel aluminum alloy keels. In order to facilitate the division of the insulation board installation area by piece and distinguish the installation position of the fire isolation zone, the angle steel aluminum alloy keels are temporarily fixed first to facilitate the installers to clearly identify the installation area. The angle steel aluminum alloy keels can be temporarily fixed with cement nails, hardwood plugs, etc.

[0029] S4. Installation of external insulation: First, temporarily fix the insulation board. You can use cement nails, hardwood plugs, etc. to fix it. After adjusting the installation angle and position of the insulation board, inject high-elastic glue (such as rubber, silicone, etc.) into the self-locking nail nut slot to absorb and disperse the stress changes of the insulation board caused by factors such as temperature changes and wind pressure. Then, drive the self-locking nails of the insulation board. Finally, inject glue at the joints of each insulation board to form each insulation board into a whole.

[0030] S5. Installation of fire isolation belt: First, lay the fire isolation belt in the cavity between the angle steel aluminum alloy keels, and place the aluminum alloy support strips on the surface after laying; then install the π-shaped cap; then inject glue into the self-locking nail nut groove of the angle steel aluminum alloy keel; then, hammer in the self-locking nails of the angle steel aluminum alloy keel; finally, hammer in the core-pulling aluminum rivets at the joint of the angle steel aluminum alloy and the cap plate to further prevent the cap plate from falling off.

It also forms a locking frame with the protrusions above and below the π-shaped capping plate, limiting the panels' displacement. Finally, the cavity between the angle steel aluminum alloy keels allows for the installation of fireproof isolation strips. The angle steel aluminum alloy keel is pre-perforated at the junction with the π-shaped capping plate where blind rivets are required, as well as at the insulation board where self-locking rivets are required, to ensure securement.

[0034] 3. Inject high elastic material glue (such as rubber, silicone, etc.) into the gap between the self-locking nail nut slot and the self-locking nail to absorb and disperse the stress changes of the insulation board caused by temperature changes, wind pressure and other factors.
