Abstract

本实用新型公开了一种仓顶交叉桁架连接结构,它包括大仓、小仓和桁架,小仓固定在大仓顶部的桁架上,在桁架交叉的中点位置设有钢管,桁架以钢管为中心对称布置,并通过其节点板固定在钢管上。本实用新型具有构造简单、各桁架受力均匀、造价低等优点。

Description

仓顶交叉桁架连接结构
技术领域:
本实用新型涉及一种电解铝生产中氧化铝贮仓的仓顶交叉桁架连接结构。
背景技术:
在电解铝工程中,常常遇到一些大型的氧化铝贮仓,由于工艺要求,需要在大仓内设置配料小仓。大仓通常是几千吨至上万吨,小仓一般是100~300吨,小仓挂在大仓的顶盖上,形成仓中仓。为了解决大仓顶盖的受力问题,通常在大仓顶盖设置钢桁架,以支承配料小仓荷载,为保证小仓的稳定,一般设置多榀桁架,几榀桁架相互交叉重叠在一起,使得主次梁传力差,而且交叉节点构造复杂、各榀桁架受力不均、造价高、不经济。
发明内容:
本实用新型的目的在于:提供一种构造简单、各桁架受力均匀且造价低的仓顶交叉桁架连接结构,以克服上述现有技术的不足。
本实用新型是这样构成的:它包括大仓(1)、小仓(2)和桁架(3),小仓(2)固定在大仓(1)顶部的桁架(3)上,在桁架(3)交叉的中点位置设有钢管(4),桁架(3)以钢管(4)为中心对称布置,并且桁架(3)的一端固定在钢管(4)上;桁架(3)也可通过其节点板(5)固定在钢管(4)上。
本实用新型与现有技术相比,其采用中间节点处理的方式,在多榀桁架相交的中点设置一传力钢管,将所有的桁架以钢管为中心对称,通过节点板与钢管连接,既解决了各榀桁架受力的均匀性问题,又将交叉节点连接构造的处理简单化,经济效益也较好。
附图说明:
附图1为本实用新型的结构示意图;
附图2为附图1的俯视图。
具体实施方式:
本实用新型的实施例:在大仓(1)顶部的多榀桁架(3)相交的中点设置一根传力钢管(4),钢管(4)的直径及厚度根据负荷大小经计算确定,将所有的桁架(3)以钢管(4)为中心对称布置,并且将每根桁架(3)的一端都焊接在钢管(4)上;为了连接更加可靠起见,也可通过节点板(5)将桁架(3)与钢管(4)焊接在一起,最后将小仓(2)固定在桁架(3)上即可。

Claims (2)

1.一种仓顶交叉桁架连接结构,它包括大仓(1)、小仓(2)和桁架(3),小仓(2)固定在大仓(1)顶部的桁架(3)上,其特征在于:在桁架(3)交叉的中点位置设有钢管(4),桁架(3)以钢管(4)为中心对称布置,并且桁架(3)的一端固定在钢管(4)上。
2.根据权利要求1所述的仓顶交叉桁架连接结构,其特征在于:桁架(3)通过其节点板(5)固定在钢管(4)上。
