Stone curtain walls, a frequent building façade material, provide modern structures with their natural texture, rich colours, and noble texture special appeal. The best insulation for exterior walls, practically speaking, though, the connecting techniques of unique elements including corners, decorative strips, waistlines, etc. of stone curtain walls often become crucial determinant of their safety and longevity. Although the conventional connection method of glueing and adding pins (or bonding reinforced stones) can satisfy some connection needs in the early stage of construction, due to the ageing and failure of adhesives, accidents of stone falling off often occur, so seriously endangering people’s life and property safety. Combined with actual engineering experience, the pertinent requirements of the “Technical Specifications for Metal and Stone Curtain Wall Engineering” (JGJ 133-2001) and “Architectural Curtain Wall” (GB/T21086-2007) make great practical relevance in optimising the connection methods of corners and special parts of stone curtain walls.
1. Problems With Traditional Connection Methods Best Insulation for Exterior Walls
Often used as a building façade, stone curtain walls give modern constructions their natural texture, rich colours, and great charm. Practically speaking, however, the joining methods of special parts like corners, decorative strips, waistlines, etc. of stone curtain walls (Best Insulation for Exterior Walls) sometimes become vital predictor of their safety and lifetime. While the traditional connection method of glueing and adding pins (or bonding reinforced stones) can meet some connection needs in the early stage of construction, due to the ageing and failure of adhesives, accidents of stone falling off often occur, so seriously endangering people’s life and property safety. Together with real engineering expertise, the relevant requirements of the “Technical Specifications for Metal and Stone Curtain Wall Engineering” (JGJ 133-2001) and “Architectural Curtain Wall” (GB/T21086-2007) have great practical relevance in optimising the connection methods of corners and special parts of stone curtain walls.
2. Best Insulation for Exterior Walls Optimized Connection Method
The conventional connection technique has to be optimised if stone curtain walls Best Insulation for Exterior Walls are to become more durable and safe. First of all, the design, processing, and construction of every stone in the stone curtain wall must entirely take independent hanging components for dependable connection with the curtain wall keel into great account. The method of independent hanging part connection guarantees that every stone has its own independent force support point, therefore preventing the condition whereby the stones are mutually dependent on one another. This connection technique satisfies the criteria of the “Technical Specifications for Metal and Stone Curtain Wall Engineering” (JGJ 133-2001), so distributing the load carried by the stone and so increasing the general stability of the stone curtain wall. Independent hangers should be installed precisely in line with the design drawings in real construction, and the connection between the hangers and the keel should be strong and dependable. Second, a one-piece design might be regarded when the stone in some areas cannot be linked to the keel with independent hangers for specific reasons. But at this point the link between the main stone (stone with independent hangers) and the stone without independent hangers (slave stone) should adopt a reliable mechanical connection method, such bolt connection, pin connection, key connection, riveting, welding, hinge connection, flange connection, clamp connection, threaded connection, tight fit connection, etc. Long-term usage of these mechanical connection techniques allows good connection performance and their strength and stability surpass those of conventional glue and pin connection. The suitable mechanical connection method should be chosen in the design and construction phase based on the real scenario and rigorously followed the pertinent standards. In any event, the conventional stone-to–stone connection uses adhesive and pins; so, one should avoid the practice of one stone depending on the bonding force of the adhesive as the major force form. Many technical applications have shown the dependabilitylessness of this connecting approach. Finding a more dependable connection method should be the main emphasis of design and construction of stone curtain walls instead of depending on the bonding performance of adhesives. The accident rate of stone falling off the corner of the stone curtain wall may be essentially lowered only by drastically altering this irrational connection method.
3. Auxiliary Role Of Adhesive Bonding And Selection Of Adhesives (Best Insulation for Exterior Walls)
Adhesive bonding can be utilised as a temporary fixing to guarantee stone splicing’s beauty and sealing in the building of stone curtain walls – Best Insulation for Exterior Walls. While splicing, adjacent plate stones can be cemented; but, the bonding of stones is simply a supporting function and cannot replace dependable mechanical connection techniques. Actually, it should be guaranteed that the construction procedure is rigorously followed and that the adhesive used for glue bonding satisfies the standards. Simultaneously, it should be underlined that dependable mechanical connection techniques cannot be replaced by glue bonding, which only serves as an auxiliary tool. Although the adhesive at the glue-bonded sections ages during the long run of stone curtain walls, it will not compromise the general safety of the stone curtain wall as long as the mechanical connection method is trustworthy. Using epoxy resin adhesive for dry hanging stone will help to guarantee the weather resistance and ageing resistance of stone bonding. Epoxy resin adhesive can somewhat lengthen the service life of the bonded part, has good weather and ageing resistance and bonding strength. Strict adherence to pertinent criteria and standards will help to guarantee that the chosen adhesives satisfy engineering needs. Concurrent with the building process, the guidelines for using the adhesives should be rigorously followed to guarantee the quality of the adhesive bonding.
4. Quality Control During Construction (Best Insulation for Exterior Walls)
One of the main links to guarantee the safety and durability of stone curtain walls – Best Insulation for Exterior Walls is quality control under construction. One crucial connection guaranteeing the quality of stone curtain wall construction is a study of building drawings. Whether special sections including corner locations, decorative strips, waistlines, etc. satisfy the standards, should be taken into consideration throughout the process of the building drawing review. Modification ideas should be presented promptly and the design unit should be obliged to maximise for design plans that fall short of the criteria. Apart from looking at the completeness, accuracy, and reasonableness of the construction drawings, the evaluation of them should also investigate and address the main and challenging issues in the building process so offering direction for next projects. Stone curtain wall construction starts mostly with the processing drawings produced by the design unit. It should be verified that the connection technique in the drawings satisfies the optimal design criteria in the process of quality control of processing drawings thereby avoiding the usage of conventional adhesive and pin connection methods. Simultaneously, one should carefully review the dimensions and marks in the drawings to guarantee the processing drawing accuracy. Regarding the discovered issues, they should be returned to the design unit in time for change; also, the processing drawings should be reissued. The buying department should carefully buy stone slabs in line with the design specifications and pertinent standards. Strictly examined and approved should be the quality, features, performance, and other markers of the stone. During the acceptance process, one should pay close attention to whether the strength, weather resistance, ageing resistance, other indicators of the stone satisfy the criteria. For stones that do not satisfy the criteria, they will be forcefully rejected to guarantee the dependable quality of the stones entering the building site. During the acceptance of stone and the building of project stone, the project department should enhance the management and monitoring of building quality. Strictly following the optimal connection technique will help to guarantee that every stone’s connection is strong and dependable during the building process. Correcting issues that develop during the building process should be done quickly to guarantee that the construction quality satisfies pertinent standards and design specifications. Simultaneously, it is essential to raise construction workers’ quality awareness and operation skills as well as boost their technical training.
