Prefabricated House Accessories
Prefabricated house accessories come in a wide variety, covering categories such as lifting, connecting, supporting, functional materials, and molds, with prices varying significantly depending on the type and specifications. The following provides an introduction based on the main types, price ranges, and functional characteristics:
1. Lifting and Connecting Accessories
These accessories are primarily used for lifting, transporting, and fixed connections during the installation of prefabricated components. For example, metal lifting components like round-head lifting pins and construction O-shaped lifting pins with holes, with prices ranging from ¥0.06 to ¥39.00, enable safe lifting by being embedded inside the components. Threaded steel lifting sleeves (¥1.00 - ¥8.00) are used for the mechanical connection of steel bars, ensuring force transmission between components. Duckbill-buckle lifting fixtures (¥39.00) and lifting rings for concrete prefabricated parts are specialized lifting tools suitable for the vertical transportation of large components. Additionally, PC embedded components (such as embedded nuts and connecting plates) enable rapid splicing between components using metal or plastic materials, with prices varying greatly depending on the specifications.
2. Supporting and Leveling Accessories
To ensure the installation accuracy of prefabricated components, supporting and leveling accessories are required. PC spacers (¥0.06 - ¥0.22) and plastic square shims are used for leveling walls or floor slabs, eliminating construction errors through combinations of different thicknesses. Solid spacers (¥0.08) and installation spacers are used to support components and prevent deformation. Inclined support construction brackets (¥51.00) and PC inclined support formwork provide temporary support for composite slabs, wall panels, etc., through adjustable designs, ensuring construction safety.
3. Functional Material Accessories
These accessories focus on enhancing component performance or construction efficiency. For example, high-performance bedding mortar (¥1200.00) and micro-expanding leveling bedding mortar are used for filling the bottom of components, eliminating gaps through micro-expanding properties and enhancing structural stability. Early-strength polycarboxylate superplasticizers (¥6000.00) can shorten the concrete curing cycle and accelerate construction progress. Rubber plugs and mortar-blocking plugs (¥381.69) are used to seal component holes and prevent mortar leakage. Fiberglass-reinforced plastic assembled profiles (¥800.00) replace traditional metal materials for special structures due to their lightweight and high-strength characteristics.
4. Large Components and Molds
Prefabricated houses also require supporting large components and molds. For example, cement prefabricated wells (¥150.00) and prefabricated cement components for power engineering (¥2000.00) are used for underground pipeline systems. Prefabricated stairs (¥3100.00) and assembled stairs improve quality through factory production. Hydraulic tilting mold tables (¥5277.25) and vibrating tilting curing mold tables are used for demolding and curing components, enhancing production efficiency. Additionally, basic materials such as concrete prefabricated house molds, steel bars, and steel fibers are also key accessories for component molding.
Summary: The selection of prefabricated house accessories should be comprehensively considered based on component types, construction techniques, and budgets. Lifting accessories focus on load-bearing capacity and durability, supporting accessories emphasize precision adjustment, functional material accessories focus on performance optimization, while large components and molds directly affect production efficiency and costs. When making actual purchases, it is recommended to compare different brands and specifications according to project requirements and prioritize qualified products that comply with national standards (such as GB/T).
