Abstract

加肋预应力雁形板,由屋面板和梁组成,特征是: 雁形板的横截面为上端带水平短翼的Y字形,沿板 长,在两屋面板之间横向设置加强肋,肋的断面为矩 形,肋中按构造要求设置钢筋;两屋面板下端的梁为 矩形,在梁下部设置有安装锚具的孔。本实用新型与 折板相比,下缝处为整体,屋面防水变得极为简单可 靠;板跨中采取加强肋,使板在施工、使用状态中,受 力良好。该板适用的领域有单层棚、库、集贸商场、中 小型体育馆、大型仓储设施等。

Description

本实用新型属于建筑结构混凝土预制构件,特别适用于板跨大、板面宽的大跨度屋面构件。
现有屋面构件中,用于做大跨度屋面构件的有V形折板,这种板重量轻,设计、制作简单,但其作为排水沟的下缝,需靠二次浇灌,很难形成整体,防水处理要求高,亦难保不漏;在制作时,预应力筋只能在板内沿板宽方向单排布置,不能集中布置,因而只能先张,不能后张,使其跨越能力受到限制。
本实用新型的目的是提供一种新型的加肋预应力雁形板,其结构合理,施工制作简单,适宜做大跨度、板面宽的屋面构件。
本实用新型的加肋预应力雁形板,由屋面板和梁组成,其特征是:雁形板的横截面为上端带水平短翼的Y字型,沿板长,在两屋面板之间横向设置加强肋,肋的断面为矩形,肋中按构造要求设置钢筋;两屋面板下端的梁为矩形,在梁下部设置有安装锚具的孔。
这种加肋预应力雁形板,其加强肋可以是V形或
形,部分设置与屋面板等高。
本实用新型与折板相比,解决了下缝防水处理难的问题,使之成为整体无缝,屋面防水变得极为简单可靠;当板跨度大时,采取加强肋,而使板在施工、使用状态中,受力良好,且板面受力合理,技术经济指标好;梁下部设置的锚具孔,为无粘结预应力筋的使用提供了方便。
本实用新型适用的领域有单层棚、库、集贸商场、中小型体育馆、大型仓储设施等。
以下结合附图及实施例,对本实用新型做进一步描述。
图1为加肋预应力雁形板结构图图2为图1的A-A剖面图一种加肋预应力雁形板,由屋面板1和梁2组成,其特征是:雁形板的横截面为带水平短翼的Y字型,沿板长,在两屋面板1之间横向设置有
形加强肋3,和V形加强肋5,肋的断面为矩形,肋中按构造要求设置钢筋;两屋面板下端的梁为矩形,在梁下部设置有安装锚具的孔4。
在跨度大于48米,板宽在6米时,在端头和每隔12米设置的 形加强肋与屋面板等高。
