Lightweight concrete plate with excellent strength and quality and manufacturing method thereof
The present invention relates to a lightweight concrete plate which is light in weight, has excellent strength and quality, is environmentally friendly, hardly deforms even after long-term use, and has excellent strength and quality because an FRP rod body or an FRP mesh made of fiber reinforced plastic (FRP) is provided inside, and a method for manufacturing the same, comprising: a concrete C main body 2 having a predetermined length, a predetermined width, and a predetermined height; the FRP rod body 5 is arranged in the main body 2; and recessed grooves (3, 4) formed on both sides of the main body (2) in the longitudinal direction. The FRP rod body (5) can be replaced with FRP. And the pipe 9 is embedded in the main body 2 and is used for inserting a constant-temperature electric wire 8. And a fastener 26 used for fixing the concrete slab on the lower supporting piece 33 is also included. A method for manufacturing a concrete slab according to the present invention comprises: a) a step for assembling a molding frame for molding a concrete slab; b) arranging and bundling the FRP rod bodies in the internal space of the forming frame; c) putting the concrete into the forming frame and vibrating the concrete at the same time; d) curing the concrete, which has been put in and vibrated, for 20-50 hours; e) decomposing the forming frame to obtain a cured concrete slab; and f) curing the demolded concrete slab for 60-100 hours to obtain the final concrete slab. The step b further comprises the step that when the FRP rod body is arranged in the inner space of the forming frame, a pipe used for inserting a constant-temperature electric wire is arranged in the inner space of the forming frame.
本发明涉及将用纤维强化塑胶(FRP：Fiber Reinforced Plastics)制造的FRP杆体或FRP网设置在内部，因此重量轻且强度和品质优良，环保，长期使用也几乎不会变形，且强度和品质优良的轻质混凝土板及其制造方法，包括：具有既定长度和既定宽度以及既定高度的混凝土C主体2；在主体2内部配筋的FRP杆体5；形成于主体2的长度方向两侧面上的凹入槽3、4。可以使用FRP来替代所述FRP杆体5。还包括：在所述主体2内部埋入设置用于插入恒温电线8的管9。还包括：用于将所述混凝土板固定到下支承件33上的紧固件26。本发明的混凝土板制造方法是，包括：a)组装用于混凝土板成型的成型框的步骤；b)将FRP杆体在成型框内部空间设置并捆扎的步骤；c)将混凝土投入成型框中的同时进行振动的步骤；d)对投入及振动结束的混凝土进行20～50小时养护的步骤；e)分解成型框，获得已经过养护的混凝土板的步骤；f)将脱模的混凝土板养护60～100小时，获得最终混凝土板的步骤。所述b)步骤中还包括：将FRP杆体在成型框内部空间设置时，将用于插入恒温电线的管在成型框内部空间设置的步骤。
