Description

Technical Field

[0001] The utility model belongs to the technical field of curtain wall construction and relates to a structure for preventing stone from falling. Background Art

[0002] With the rapid growth of my country's economy in the past thirty years, the construction industry has been deeply developed, and stone curtain walls have been widely used and developed in various types of hotels, stations, airports, commercial complexes, exhibition halls, gymnasiums, museums, etc. Due to the imperfect safety considerations of early stone curtain walls, some projects exposed some problems of stone falling, which greatly affected the safety of stone curtain walls.

[0003] Since stone is a natural material, its compressive strength varies due to factors such as mineral composition, crystal coarseness, uniformity of cementing material, load area, angle between load and cleavage, etc. During the implementation of the project, various factors may also lead to negligence in quality control environment. Architects and owners are not familiar with the characteristics of this material, which leads to certain risks in using it in large areas in the ceiling to ensure the appearance effect. Therefore, the new regulations issued this year have made provisions for anti-fall measures in the safe use of stone, which has played a good regulatory guarantee for promoting the installation and use of stone curtain walls.

[0004] However, there is no clear regulation on the specific methods and structures of anti-fall measures for stone curtain walls. Therefore, in the specific implementation process, many projects only focus on the fixing of the stone at a certain point, ignoring the natural properties of the stone. There is uncertainty about breakage and falling, and too many anti-fall point fixations on stone panels will weaken the strength of the stone itself. The breakage of stone is often localized. Therefore, how to prevent the stone from falling due to local damage has become the current research focus. Utility Model Content

[0025] See also Figures 1 to 5 The utility model discloses a structure for preventing stones from falling, comprising a stone fixing system and an anti-falling suspension system.

[0026] Among them, the stone fixing system includes a stone panel 1, a stainless steel back bolt 2, a stone adhesive 3, and an aluminum plate 4. The entire stone fixing system is to bond and fix the stone panel 1 in a certain area through the stone adhesive 3 and the aluminum plate 4, and at the same time, the aluminum plate 4 and the stone panel 1 are mechanically fixed through the stainless steel back bolt 2; the anti-fall suspension system includes an aluminum alloy hanger 5, a steel wire spring rope 6, and a steel angle code 7. The aluminum alloy hanger 5 is fixedly connected to the stone panel 1 through the stainless steel back bolt 2, one end of the steel wire spring rope 6 is connected to the steel angle code 7, and the other end is connected to the aluminum alloy hanger 5.

[0027] The stainless steel back bolts 2 of the stone fixing system in this embodiment are point fixing forms of the stone panel 1, and are arranged at certain intervals in the weaker areas of the stone panel 1. The aluminum plate 4 and the stone adhesive 3 are surface fixing forms of the stone panel 1. The aluminum plate 4 is arranged in a certain area near the stainless steel back bolts 2, and the stone adhesive 3 is used to bond the stones in the entire area to ensure that the stones in this area will not fall directly when cracks occur.

[0028] The aluminum alloy hanger 5 in this embodiment mechanically fixes the aluminum plate 4 to the stone panel 1 through the stainless steel back bolt 2. One end of the steel spring rope 6 is connected to the steel angle code 7, and the other end is connected to the aluminum alloy hanger 5. When a certain area of ​​the stone panel 1 near the stainless steel back bolt 2 is damaged, it will not fall off immediately due to the bonding effect of the stone back glue 3, which minimizes the risk of stone falling and ensures the safety of the stone curtain wall.

[0029] The aluminum alloy pendant 5 adopts an "h"-shaped profile made of aluminum alloy, which has the advantages of light weight, high strength, corrosion resistance, long life, etc. In addition, the aluminum alloy material is easy to process and can be recycled and reused, which meets the requirements of environmental protection and sustainable development.

[0030] The use of the structure for preventing stone from falling in the utility model comprises the following steps:

[0031] S1, preparation work: determine the fixing points and distribution area of ​​the stone panel 1 in the construction area in advance, and prepare all materials according to the design drawings and relevant construction requirements;

[0032] S2, Laying out lines and establishing skeletons: Laying out lines and positioning are performed based on the design drawings, and the primary and secondary keels of the curtain wall and the main structure are connected in place. At the same time, the position of the steel angle code 7 needs to be leveled and suspended during the installation process to ensure that the shape meets the design requirements.

[0033] S3, component processing: the stone panel 1, aluminum plate 4 and aluminum alloy hanger 5 are pre-processed in the factory according to the size and shape of the design drawings, and their surfaces are cleaned, painted, etc., and then the stone panel 1 and aluminum alloy hanger 5 are processed, cut and drilled, and the aluminum plate 4 is cut according to the design size.

[0034] S4, stone fixing system assembly: according to the design drawings, the stone panel 1, stone adhesive 3, and aluminum plate 4 are bonded according to the designed position, and the bonding and fixing work is completed after curing. Then the processed aluminum alloy hanger 5 is aligned with the back bolt hole and connected and fixed with the stainless steel back bolt 2 and the stone panel 1.

[0035] S5, installation of the anti-fall suspension system: one end of the steel spring rope 6 is passed through the fixing hole on the aluminum alloy hanger 5 for connection and fixation, and the other end is temporarily fixed.

[0036] S6, on-site installation: transport the assembled stone panel 1 and its supporting components to the predetermined location on site, fix the other end of the steel spring rope 6 to the steel angle code 7 on site, and complete the fixing of the stone hanging system at the same time, thus completing the installation process.

[0037] S7, Sealing and concealment work: Complete the direct sealing and cleaning work of the stone panel 1 to ensure that the design effect and functional requirements are met.

[0038] The utility model is different from the stone point anti-falling measures commonly used in most projects at present by setting two fixing structures of bonding and mechanical fixing. It can simultaneously meet the point fixation and surface fixation of stone anti-falling, and keep the stone from falling for a certain period of time after it is damaged or broken, thereby providing sufficient preparation time for the later maintenance and repair of the stone curtain wall, and avoiding personal and property losses caused by the falling of stones.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
