Polystyrene foam molding applications within the hollow plate

1, with rubber bladder for endometrial hollow plate beam applications in the province: 1-1 of 1987, the province Xinxiang-Zhengzhou highway, 16 m, 20 m, 30 m prestressed hollow began to apply; 1 -21 992 years, the Kaifeng to Zhengzhou to Luoyang expressway construction of large-scale application; 1-3 province is located in the Central Plains, the project more than in the plains, roads and bridges more than 80% are small and medium-span of 10 ~ 30m, so a maximum Hollow Slab type; 1-4 Advantages: simple structure, easy crossing, building height is low, easy to prefabrication, transportation and lifting the board in the process of stability, not capsize; 1-5 Disadvantages: After ten years of application, gradually exposed. 2, hollow plate beam main disease and responses: The main disease 2-1 hollow plate roof and floor thickness is inadequate; insufficient reinforcement steel protective layer; hinge joints between 2-2 hollow concrete shed, water seepage, efflorescence; between 2-3 board dislocation; bottom longitudinal cracks; 2-4 bearing severe shear deformation; bearing age; bearing off, three or two hollow force. 2-1 Measures to improve internal and external template by varying the bore hole double; 2-2 from small tongue and groove tongue and groove joints larger joints, increasing the connecting bars; pouring together with board member ends 2-3, three side nap, enhanced waterproof adhesive; 2-4 capped ends into partitions, increase torsional, anti-distortion rigidity. 3, even Huo Zhengzhou Rebuild Project in hollow beam construction major improvements: Compared with the old hollow Lianhuo line has five improvements: a hole big plates, using polystyrene foam inside the mold to replace conventional rubber capsules, to ensure accurate positioning hole; Second, unified custom high strength steel template chunk, ensure dimensions; third, increase the hollow tongue and groove joints, increasing the lateral tendon, enhance the lateral connections between the plates; three four, hollow plate Picking process, enhance the cohesive force; V. tip and the beam pouring together, increase torsional rigidity. First, the use of expanded polystyrene make the mold: Advantages: hollow top, bottom and side wall thickness dimension can be effectively guaranteed. It solves the internal model is easy to use rubber capsules deviation, resulting in quality problems floating hollow top, side wall thickness locally produced ultra-thin. Note: Positioning problem 1, located Fixtures. 2, using fixed plastic pad under the top surface of hollow steel mesh polystyrene pressed into the mold to a fixed position. Profile: Henan Wansheng Color LLC is prestressed bridge with in-mold foam, Color Room, steel truss room, prestressed bridge with anchor plate, external wall insulation board and other professional production and processing company, has a complete and scientific quality management system. Color Henan Wansheng limited liability company's integrity, strength and quality of products recognized by the industry. Welcome friends to visit, guidance and business negotiation. Our research and development of endometrial bridges polystyrene foam board to solve the shortage of precast slab bridge capsule floating in inflatable roof thickness and technical problems, bridge hollow slab of polystyrene foam used in place of inflatable capsule, to ensure accurate positioning within the mold design size and structure intact. Get the relevant experts and customer recognition and praise. Project: Henan Huai solid two standard high-speed civil, Henan Huai solid high-speed civil three standard, Henan Huai solid four-speed civil standard, Henan Huai solid civil six-speed standard, Henan Huai solid seven-speed civil standard, Henan Province, high-speed civil Deng three standard Henan Xichuan X110 line first precast plant, Xichuan X110 precast plant \\ third line, Beijing set a new high-speed standard Pingdiquan call a mixing station, Beijing set a new high-speed standard Tuchengzi call a mixing station, Beijing The new high-speed set call a standard 18 sets mixing station
