Abstract

一种套装式单柱钢管塔,它包括塔体和附载件,所述的塔体由至少三段组成,各段塔体可全部套装在一起,内层的每段塔体在底部连接处设有断口,相邻塔体在断口处通过第一螺栓穿钉相连接。采用上述技术方案的本发明,内层的每段塔体在底部连接处设有有断口,相邻塔体在断口处通过第一螺栓穿钉相连接,这样断口处向外扩胀,使得内层的塔体与外侧的塔体之间可以紧密地连接在一起,然后再用螺栓穿钉将其固定,此时螺栓穿钉就不需要承担很大的张力,从而使得塔体连接更加稳定牢固,避免了事故的发生,也延长了塔体的使用寿命。

Description

一种套装式单柱钢管塔
技术领域
本发明涉及一种单柱钢管塔,特别是一种可广泛应用于市区各种高度较高线路、路灯架设和广告牌等的单柱钢管塔。
背景技术
随着城市规模的不断扩大和城市层次的不断提高,对城市的规划水平也提出了越来越高的要求。单柱钢管塔由于具有占地面积小、强度高、不用拉线、造型简洁明快等诸多优点,被越来越多采用在城市高压输电线路、广告塔等各种高度较高的应用中。目前常用的单柱钢管塔多为分体方式,塔体之间多采用法兰盘螺栓连接或为冲装连接,但由于塔体还是较长,安装、运输起来非常麻烦。
专利号为200810140743.3,发明名称为“一种套装式单柱钢管塔”的发明专利,虽然也公开了一种套装式钢管塔,但是在两段连接的地方利用螺栓穿钉进行固定连接。这样在安装完成后,上部的塔重压在螺栓穿钉上,长时间很容易造成螺栓穿钉生锈或断裂,造成事故。另外,内层塔体和外层塔体结合性不好,因此螺栓穿钉也承受了很大的张力,存在稳定的安全隐患。
发明内容
本发明的目的是提供一种稳定牢固的套装式单柱钢管塔。
为实现上述目的,本发明采用以下技术方案:
本发明包括塔体和附载件,所述的塔体由至少三段组成,各段塔体可全部套装在一起,内层的每段塔体在底部连接处设有断口,相邻塔体在断口处通过第一螺栓穿钉相连接。
上述的塔体为直筒形或锥台形,横截面为六边形或八边形。
在所述中间各段塔体和最上面的一段塔体顶部均设有钢鼻。
采用上述技术方案的本发明,内层的每段塔体在底部连接处设有有断口,相邻塔体在断口处通过第一螺栓穿钉相连接,这样断口处向外扩胀,使得内层的塔体与外侧的塔体之间可以紧密地连接在一起,然后再用螺栓穿钉将其固定,此时螺栓穿钉就不需要承担很大的张力,从而使得塔体连接更加稳定牢固,避免了事故的发生,也延长了塔体的使用寿命。
附图说明
图1为本发明的整体结构示意图。
图2为图1中A-A向视图。
具体实施方式
如图1、图2所示,本发明包括塔体和附载件,上述的塔体由至少三段组成,各段塔体可全部套装在一起。为方便说明,本发明以三段塔体为例加以说明。
本发明中,塔体由顶段塔体4、中段塔体5和底段塔底6组成。其中,在中间各段塔体和最上面的一段塔体顶部均设有钢鼻1;在顶段塔体4上,通过第二螺栓穿钉3固定附载件2;上述的底段塔体6设置在底座8上。需要说明的是,上述的塔体为直筒形或锥台形,横截面为六边形或八边形。
为稳定牢固起见,本发明中内层的每段塔体在底部连接处设有多个断口9,相邻塔体在断口处通过第一螺栓穿钉7相连接,如图2所示。
本发明的原理是:将内层塔体在底部开有断口后,断口处向外扩胀,使得内层的塔体与外侧的塔体之间可以紧密地连接在一起,然后再用螺栓穿钉将其固定,此时螺栓穿钉就不需要承担很大的张力,从而使得塔体连接更加稳定牢固。
