建興塑料墊塊規格齊全 價格低

日 期:2016-9-13 9:40:30 已 閱:1844 次

  塑料墊塊又名鋼筋保護層墊塊,在工程建筑中以及框架結構里,放在鋼筋與模板之間,固定好鋼筋位置,避免鋼筋裸露出現腐蝕現象。在塑料墊塊承受外力保護層對鋼筋有固力作用,主要就是利用混凝土與鋼筋間的錨固力,兩者緊密作業,共同完成工作。塑料墊塊保護層過薄,導致它的錨固力降低結構抵抗軸力與彎矩的作用。塑料墊塊保護層過厚混凝土表面則易產生裂縫,影響鋼筋在混凝土中受力,F在市面上的塑料墊塊規格很是齊全,比如:梅花形、圓形、錐形等形狀;尺寸:3.5cm、4cm、4.5cm;、價格分別元2.0元/件、5.0元/件、7.0元/件、8.0元/件以及10.0元/件,但是具體的價格要根據購買商品的數目而定。
