Description

Technical Field

[0001] The utility model relates to the technical field of building exterior wall facilities, in particular to an anti-falling structure for a building exterior wall insulation layer. Background Art

[0002] With the global emphasis on energy conservation, emission reduction and sustainable development, energy conservation in buildings has become an important issue. External wall insulation technology can effectively reduce energy loss in buildings, reduce carbon emissions and promote low-carbon development. In recent years, the frequent falling off and fire accidents of external wall insulation materials have attracted great attention from the society. Faced with the limitations of traditional external wall insulation materials, such as flammability, combustibility and falling off, the industry is seeking safer and more reliable new insulation materials and structural designs to improve the fire resistance and structural stability of building exterior walls. Many old buildings did not use modern insulation materials or designs during construction, resulting in poor insulation effects and safety hazards. With the advancement of urban renewal and building renovation, the demand for external wall insulation renovation of these buildings is increasing, the insulation material market is constantly developing, and new materials and systems are constantly emerging, but at the same time there is also the problem of uneven quality. The reasonable selection and application of insulation materials is not only related to the energy-saving effect of buildings, but also to building safety and the healthy development of the market.

[0003] In the prior art, in recent years, the problem of the shedding of building exterior wall insulation materials has gradually become a focus of widespread social attention. This phenomenon not only occurs frequently, but also has extremely serious consequences. First, the shedding of the exterior wall insulation layer greatly affects the overall beauty of the building, making the appearance of the building mottled and affecting the image of the city. Secondly, the peeling of the insulation layer will also shorten the service life of the building, increase maintenance costs, and cause economic losses to the owner. More importantly, the shedding of exterior wall insulation materials poses a direct threat to personal safety. The shedding insulation layer may hit pedestrians or objects, especially in the city center where high-rise buildings are lined up, and this risk is always present. Therefore, solving the problem of the shedding of the exterior wall insulation layer and ensuring the safety and stability of the building have become one of the technical challenges that the current construction industry urgently needs to solve. Take effective measures to protect people's lives and property, maintain the beauty of the city and the long-term use of buildings. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a structure for preventing the thermal insulation layer of a building exterior wall from falling off.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a structure for preventing the thermal insulation layer of a building exterior wall from falling off, comprising a keel frame, wherein the upper end surface of the keel frame is detachably connected with a thermal insulation board, the internal threaded connection of the keel frame is connected with a fixing bolt, the surface of the fixing bolt is slidably connected with a sliding ring, a plurality of the sliding rings are rotatably connected with a spreading piece, a spring piece is fixed at the bottom of the spreading piece, a plurality of the spreading pieces are connected by the spring piece, a pressing plate is fixed on the circumference of the fixing bolt, and in the prior art, in recent years, the falling off problem of thermal insulation materials of building exterior walls has gradually become the focus of widespread social attention. This phenomenon not only occurs frequently, but also brings extremely serious consequences. First, the falling off of the thermal insulation layer of the exterior wall greatly affects the overall beauty of the building, making the appearance of the building mottled and affecting the image of the city. Secondly, the peeling off of the thermal insulation layer will also shorten the service life of the building, increase the maintenance cost, and cause economic losses to the owner. More importantly, the falling off of the thermal insulation material of the exterior wall poses a direct threat to personal safety. The falling off thermal insulation layer may hit pedestrians or objects, especially in the city center where high-rise buildings are everywhere, and this risk is always present. Therefore, solving the problem of the outer wall insulation layer falling off and ensuring the safety and stability of the building have become one of the technical challenges that the current construction industry urgently needs to solve. Take effective measures to protect people's lives and property, maintain the beauty of the city and the long-term use of the building. In response to such problems, the utility model adopts a card block method. When the staff installs the insulation layer, the staff first installs the keel frame inside the wall and fixes it with filling materials. Then, the staff accurately positions it according to the threaded holes on the surface of the keel frame. Subsequently, the insulation board is placed on the surface of the keel frame. The staff will tighten the fixing bolts, and this action will drive the pressure plate to move downward. As the pressure plate descends, the sliding ring is also driven to move downward. At this time, the extruded expansion piece will expand around, and through this expansion action, the insulation board and the keel frame are firmly fixed together. Through this series of operations, the utility model effectively avoids the problem of the insulation board falling off, ensures the stability and safety of the building's exterior wall, and also improves the construction efficiency and the overall beauty of the building.

[0006] Preferably, a fiberboard is fixed to the inner wall of the keel frame, and a honeycomb groove is provided on the surface of the fiberboard. In the prior art, the design of the traditional keel frame often has a large number of blank areas. These blank areas not only affect the overall stability of the frame, but also the uneven support capacity of the frame due to the large number of blank areas, which easily leads to deformation or falling off of the building exterior wall insulation material when subjected to external force, increasing safety hazards. Secondly, the existence of the blank area also reduces the sealing performance of the frame, making it easy for air and moisture to penetrate, thereby affecting the insulation effect and service life of the insulation layer. The installation process of the traditional keel frame is often cumbersome and complicated, requiring a lot of manpower and time for positioning, fixing and adjusting, increasing the construction cost. At the same time, due to the influence of the blank area, cracks are prone to appear at the connection between the frame and the wall, affecting the aesthetics of the building. In summary, the problems caused by the large number of blank areas in the traditional keel frame mainly include: increased safety hazards, reduced insulation performance, increased construction costs and reduced aesthetics. Therefore, in response to these problems, it is necessary to improve the traditional keel frame to improve its overall stability and use effect. In response to such problems, the method of installing a honeycomb groove structure fiberboard is adopted to effectively solve the problem of multiple blank areas. Because the layout of the honeycomb grooves is tight and uniform, they can form a series of small support points on the surface of the fiberboard, which can effectively disperse and bear the pressure and impact from different directions. This way of dispersing pressure greatly increases the stability of the entire structure, thereby reducing the risk of deformation or falling off due to external forces. The structural design of the honeycomb groove also helps to reduce the expenditure on filling materials. It reduces the waste of materials, simplifies the construction steps, and improves the construction efficiency. It improves the stability and safety of the building exterior wall insulation materials, and effectively reduces the expenditure on filling materials and reduces the construction cost.

[0007] Preferably, a filling groove is provided at the bottom of the insulation board. During the installation process, the staff can easily inject the filling material into the filling groove, which simplifies the construction steps and improves the construction speed. At the same time, due to the presence of the filling groove, the filling material can be more evenly distributed at the bottom of the insulation board, further enhancing the bonding force between the insulation board and the wall and improving the overall stability.

[0008] Preferably, a support frame is fixed at the bottom of the keel frame. The utility model effectively reduces the influence of the insulation board's own weight on the fixing bolts through the design of fixing the support frame at the bottom of the keel frame, improves the stability and durability of the installation structure, and also improves the construction efficiency, ensuring the safety and reliability of the insulation board during use.

[0009] Preferably, a trapezoidal block is provided at one end of the insulation board, and a trapezoidal groove is opened at the other end of the insulation board. The utility model designs the trapezoidal block and the trapezoidal groove at both ends of the insulation board respectively, so that the splicing between the insulation boards is more stable, the installation efficiency is improved, the maintenance cost is reduced, and the utility model demonstrates the high innovation and practicality of the utility model.

[0010] Preferably, the surface of the sliding ring is covered with a rubber sleeve. The utility model effectively improves the durability and safety of the insulation layer fixing structure by covering the rubber sleeve on the surface of the sliding ring, and performs particularly well in preventing bolt corrosion, demonstrating the high innovation and practicality of the utility model.
