Abstract

本发明公开了一种自保温预应力砼双T板，它为水平顶板及沿其长度方向下侧布置的两条竖直梁形成的T型整体预制件。其中水平顶板采用密肋夹心的构造形式，减少了水平顶板中砼的用量，降低了自重，提高了刚度及承载力。同时为进一步提高承载能力及刚度，竖直梁中的受力钢筋采用预应力钢筋；为减少热桥影响，纵肋带、横肋带中的混凝土采用结构保温轻骨料砼。所以本发明在不增加自重、保证承载力的同时还能保温隔热，降低了造价、简化了施工。

Description

一种自保温预应力砼双T板
技术领域
本发明涉及一种预制的双T板，具体涉及一种自保温预应力砼双T板。
背景技术
随着建筑工业化的快速发展，各种装配整体式的钢筋砼预制构件得到快速发展，其中预制预应力双T板由于具有跨度大，承载力强,整体性好,施工方便，缩短工期等特点，正在广泛用于各种大跨度建筑的楼板和屋面。但目前应用的预制预应力双T板，为减轻自重，降低生产、运输和安装成本，其顶板的厚度太薄，一般只有50mm左右，这样对于有保温和隔音要求的楼、屋面来说，要满足楼、屋面的保温隔热及隔音效果，就必须在双T板的顶面上另做保温隔热隔音层，如此一来，就要增加预制双T板的综合施工成本。因此，为加快双T板的推广，提高双T板的综合经济优势，，研发新型的自保温预制双T板是非常必要的。
发明内容
本发明的目的在于提供一种自重轻、整体性好的自保温预制预应力砼双T板。
本发明公开了一种自保温预制预应力砼双T板，它为水平顶板及沿其长度方向下侧布置的两条竖直梁形成的T型预制构件。
所述水平顶板为矩型板，竖直梁为与水平顶板等长的矩型梁，两条竖直梁沿水平顶板长度方向布置于其宽度方向的中心位置处。
所述水平顶板为由上、下面板及位于两者之间的交叉布置的纵、横肋带围成的框架型结构，纵、横肋带分别沿上、下面板的长度方向和宽度方向布置将上、下面板之间的区域分隔为若干独立空腔，独立空腔内均填充相应的填充块。
为提高屋面板和板接缝处的防水抗渗能力，在所述水平顶板的两条边纵肋上沿长度方向开有凹槽，上、下面板中的钢筋采用焊接钢筋网片。
为提高板的承载能力及刚度，竖直梁中的受力钢筋采用预应力钢筋。
为减少热桥影响，纵、横肋带中的混凝土均采用结构保温轻骨料砼。
为提高保温隔热效果，所述轻质填充块采用轻质保温材料。
本发明为水平顶板以及两条竖直梁的T型整体预制件，其水平顶板采用密肋夹心的构造形式，减少了水平顶板中砼的用量，降低了自重，又加大了本身的宽度和高度，提高了刚度及承载力。所以本发明在不增加自重、保证承载力的同时还能保温隔热，在保证其整体性及其安全性的前提下降低了造价、简化了施工。
附图说明

图2为本发明沿轻质填充块的横截面剖视图。
具体实施方式
如图1-2所示，本实施例公开了一种预制自保温预应力砼双T板，它为矩型的水平顶板1以及沿其长度方向布置于其下方的两条竖直梁2的T型整体预制件，竖直梁2为与水平顶板1等长的矩型梁，竖直梁2沿水平顶板1长度方向的等间距布置于其宽度方向的中心位置处。其中水平顶板1包括上面板11、下面板12及纵横交错的均布于两者之间的纵肋带13与横肋带14，纵肋带13、横肋带14将上面板11、下面板12之间的区域分割为若干独立空腔，独立空腔内填充有相应的填充块轻质填充块15，填充块15由轻质保温材料制成。
为提高板与板长度方向接缝处的防水抗渗能力，在顶板1的两条边纵肋上沿长度方向开有凹槽16。同时为了提高承载能力及刚度，竖直梁2中的受力钢筋采用预应力钢筋。为了减少热桥影响，纵肋带13、横肋带14中的混凝土均采用结构保温轻骨料砼。为提高屋面的抗渗能力，上面板11、下面板12中的钢筋采用焊接钢筋网片。
本实施例为水平顶板以及竖直梁的T型整体预制件，其水平顶板采用密肋夹心的构造形式，减少了水平顶板中砼的用量，降低了自重，又加大了本身的宽度和高度，提高了刚度及承载力。同时为了进一步提高承载能力及刚度，竖直梁2中的受力钢筋采用预应力钢筋；为了减少热桥影响，纵肋带、横肋带中的混凝土均采用结构保温轻骨料砼。所以本实施例在不增加自重、保证承载力的同时还能保温隔热，在保证其整体性及其安全性的前提下降低了造价、简化了施工。
