What are the functions of building accessories

       Architectural accessories are the "connectors" between building structure, function, and appearance, covering various components from foundation connection to decorative finishing. Their core functions can be divided into four dimensions: "structural support, functional implementation, safety assurance, and appearance optimization", as follows:

1、 Structural Support and Stability: Ensuring the Overall Safety of Buildings

       This is the core foundation function of building accessories, which ensures the load-bearing capacity and stability of the building structure by connecting and reinforcing components, avoiding deformation or collapse:

       Connection fixing: such as bolts, nuts, and embedded parts (metal parts pre embedded in concrete), used to connect steel structures, concrete components (beams, columns, wall panels), door and window frames with the main structure, achieving "rigid connection between components"; Grouting sleeves and connectors in prefabricated buildings can be used to splice prefabricated wall panels and composite panels, ensuring the overall structural integrity.

       Reinforcement and strengthening: such as seismic brackets (fixing pipes and cables), corner brackets (reinforcing the right angle connection between door and window frames and walls), and steel bar connection sleeves (connecting two sections of steel bars to enhance the tensile and compressive strength of concrete structures), can enhance the load-bearing capacity of local weak areas, especially in extreme scenarios such as seismic and wind resistance, and reduce structural damage.

       Stress dispersion: For example, rubber bearings (used between beams and piers in bridges and large buildings) and shock-absorbing pads can distribute concentrated stress to a larger area through their own elastic buffering of load impacts (such as vehicle traffic and earthquake shaking), protecting the main structure from direct damage.

2、 Function implementation: meet the needs of building use

      Building accessories are the key to the "usability and ease of use" of buildings, directly supporting the implementation of core functions such as water, electricity, ventilation, and lighting

      Water and electricity system matching: such as pipeline connectors (elbows, tees, flanges), used for turning, branching, and sealing of water supply, drainage, and heating pipelines to avoid water and heat leakage; Cable trays and conduit boxes regulate the routing of electrical circuits, protect wires from corrosion or external damage, and facilitate maintenance.

       Ventilation and lighting: such as skylight opening and closing accessories (hinges, push rod motors), controlling the opening angle of the skylight to achieve natural ventilation inside the building; The hardware components (handles, locks) of the curtain wall opening fan not only fix the glass curtain wall, but also can be flexibly opened, balancing the needs of lighting and ventilation.

      Flexible space adjustment: such as partition connectors (tracks, hinges), used for the installation of movable partitions and folding doors, to achieve flexible space splitting and merging (such as conference rooms, exhibition halls); Scaffold accessories (buckles, crossbars), although temporary construction accessories, can build a stable work platform and ensure the efficiency of structural construction during the construction phase.

3、 Security guarantee: Avoiding risks and hidden dangers during use

      From fire prevention and theft prevention to personal protection, building accessories reduce safety risks during building use through "active protection" or "passive warning":

       Fireproof and flame retardant: such as fireproof sealing strips (embedded in door and window gaps, curtain wall joints), which expand and seal gaps when exposed to high temperatures, preventing the spread of flames and thick smoke; Fire dampers (installed in ventilation ducts) automatically close in the event of a fire, cutting off the path of the fire spreading through the ducts.

       Personal protection: such as the column connectors of balcony guardrails and the fixing bolts of stair handrails, to ensure the load-bearing capacity of guardrails/handrails and prevent personnel from falling; Anti slip strips (attached to the edges of stair treads and corridor floors) increase the friction coefficient to prevent pedestrians from slipping.

       Anti theft and protection: such as door and window locks (anti-theft lock cores, heaven and earth locks), enhancing the anti pry performance of doors and windows; External wall insulation nails (fixed insulation boards) prevent the insulation layer from falling off and injuring pedestrians, while ensuring the durability of the insulation system.

4、 Appearance optimization and detail improvement: enhancing the aesthetics and texture of buildings

       Building accessories are not only "functional components", but also the key to enhancing the visual effect of buildings, especially in decorative scenes:

       Closing and beautification: such as skirting (covering the gap between the wall and the ground), decorative lines (door and window frame lines, wall corner lines), covering defects at the joints of components (such as gaps and inequalities), making the transition between the wall and the ground smoother; The sealing strips and decorative buckle plates of the curtain wall conceal the connection points between the glass and the frame, making the appearance of the curtain wall more concise and unified.

       Style adaptation: such as arch of wooden architecture accessories of Chinese architecture (although it has a structural role, but the core is to reflect the traditional style), carved decorations of European architecture (window sill carved, cornice accessories), which echo the overall style of the building through modeling design to enhance cultural attributes; The invisible hinges and hidden handles in modern minimalist style reduce the exposure of components and achieve a "minimalist visual effect".

       Detail texture: such as metal textured door handles and aluminum alloy decorative strips, which enhance the local texture through materials and processes (such as wire drawing and electroplating); The imitation stone brick connectors on the exterior wall ensure neat splicing of the imitation stone bricks and restore the high-end visual effect of the stone curtain wall.
