Description

Technical Field

[0001] The present invention 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 and an installation method. Background Art

[0002] At present, the building exterior wall insulation technology mainly adopts the method of insulation board pasting and anchor reinforcement. However, in actual application, due to the influence of non-standard construction, material aging, and environmental factors (such as wind pressure, temperature changes, etc.), the insulation board often falls off, which poses a great hidden danger to building safety. Based on actual engineering 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 exterior wall insulation construction technology of housing 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 pressure plate components for reinforcement, as follows:

[0004] The patent with publication number CN116025075A discloses a method for anti-falling anchoring construction of thermal insulation panels attached to the exterior walls of existing buildings. However, the patent method simply strengthens the anti-falling anchoring, which has the following serious defects: dense anti-falling anchoring will compress the thermal insulation material, causing the performance of the thermal insulation layer to decrease and affecting the thermal insulation effect; over time, the anchor nails may fall off due to loosening, and there are still safety hazards; the outer surface structure of the wall may be damaged, affecting the overall stability and safety of the building; a large number of anchor nails and other auxiliary materials are required, which consumes a lot of labor, resulting in increased construction difficulty and cost.

[0005] Patent No. CN118653585A discloses an anti-falling structure for an ecological insulation board. The patent adopts a bearing plate, a supporting strip and a connecting piece structure. The supporting groove formed between the supporting strip and the bearing plate for accommodating the ecological insulation board is used to reduce the probability of the ecological insulation board falling directly from the exterior wall. The technology mainly adopts partitioned glue injection to prevent the ecological insulation board from falling off.

[0006] Although the prior art disclosed in the above patents and papers has alleviated the problem of insulation board falling off to a certain extent, it still has disadvantages such as potential safety hazards in the later stage, difficulty in construction, high cost, inconvenient maintenance, aging of adhesives, loosening of anti-falling anchors, etc. At the same time, the above technologies have all taken the insulation problem into consideration. Summary of the invention

[0007] The purpose of the present invention is to solve the technical problems of poor insulation, aging of adhesives and easy loosening of anti-falling anchors in the prior art, and to provide a building exterior insulation anti-falling device and installation method. The device has the advantages of simple structure, convenient construction and low cost, can effectively prevent the building facade insulation board from falling off, and can also take into account the setting of fire isolation belts.

[0008] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0010] 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.

[0011] In one embodiment, the first locking assembly includes a fireproof isolation zone arranged between two adjacent insulation boards, two angle steel aluminum alloy keels arranged at the upper and lower ends of each fireproof isolation zone, a π-shaped cap plate and two self-locking nails, each angle steel aluminum alloy keel is stepped, each angle steel aluminum alloy keel is partially embedded in the corresponding insulation board, the π-shaped cap is arranged outside the fireproof isolation zone and the two angle steel aluminum alloy keels, and the two horizontal sections of the legs of the π-shaped cap extend into the interior of the two adjacent insulation boards respectively;

[0012] Each locking nail passes through a horizontal section of a supporting leg of a corresponding π-shaped cap, and a corresponding angle steel aluminum alloy keel is locked in a self-locking nail nut groove.

[0013] Specifically, the insulation board is installed on the building facade (exterior wall) to play the role of building thermal insulation. The fire isolation belt plays the role of preventing the flame from spreading along the insulation board in case of fire.

[0014] 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.

[0015] 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.

[0016] In one embodiment, the inner sides of the two vertical sections of the legs of the π-shaped cap 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.

[0017] Specifically, the angle steel aluminum alloy keel serves to separate and limit the insulation board, while absorbing part of the gravity of the insulation board; in addition, it can form a locking frame with the protruding parts of the upper and lower π-shaped capping board to limit the displacement of the insulation board; finally, the fireproof isolation belt can be paved in the cavity between the angle steel aluminum alloy keels. The angle steel aluminum alloy keel is pre-perforated in advance at the location where the core-pulling aluminum rivets are required at the junction with the π-shaped capping board, and at the insulation board where the self-locking nails are punched, so as to play a fixing role.

[0018] In one embodiment, each angle steel aluminum alloy keel is provided with a portion for installing a blind aluminum rivet at the joint with the π-shaped cap plate.

[0019] In one embodiment, an aluminum alloy stay is provided between the fireproof isolation belt and the corresponding π-shaped cap.

[0020] Specifically, the aluminum alloy stays play a role in preventing the deformation of the two angle steel aluminum alloy keels above and below the fire isolation.

[0023] In one embodiment, a highly elastic material glue is injected into the gap between the self-locking nail nut groove and the corresponding self-locking nail.

[0024] Specifically, a high elastic material glue (such as rubber, silicone, etc.) is injected 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.

[0028] S2. For new buildings, the self-locking nail nut slots can be pre-buried according to the design drawings; for existing buildings, the wall surface base should be treated first, and then the wall should be drilled according to the drawings, and then the self-locking nail nut slots should be tapped;

[0029] 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.;
