Abstract

本实用新型公开了一种塑料拉伸菱形网状结构材料,所述的网状结构材料包括多个节点,节点之间设有筋带,其特征在于:每个节点连接三个或者六个筋带,使得相邻的四个节点和此节点之间的筋带连接形成菱形单元孔,所述的网格结构为此多个菱形单元孔组成,相邻两菱形单元邻边重合。本实用新型能够同时承受多向载荷,节点受到撕裂破坏的几率减少,同时其整体的结构强度增强,受力状态更为合理。

Description

一种塑料拉伸菱形网状结构材料
一:技术领域
本实用新型涉及一种多向受力塑料拉伸格栅,尤其是一种菱形网状结构材料,其用于土木工程中作为加筋加固材料或者用于建筑工程中作为防护和隔离材料。
二:背景技术
塑料拉伸网状结构材料有多种生产方式,有的采用塑料条带焊接成井字形或者方形或者矩形结构,但是其接点强度很难满足施工要求,往往起不到加筋加固作用;有的采用聚酯纤维或者玻璃纤维经过编织成井字形或者矩形结构,然后在其表面涂覆有机防护层的结构,这种结构的接点强度也很难满足工程对强度的需要,尤其很难起到整体加强的作用;有的采用塑料板材经过冲出整排的方形或矩形的孔,其孔的形状可以是多种形式,如圆形、椭圆形、长圆形、方形、矩形等,经过纵向、横向逐步拉伸或者同步拉伸,从而得到井字形或者方形、矩形孔形状的网状结构材料,这种结构材料在承载能力方面比起上述焊接、编织形成的格栅具有了整体性好、节点强度高的效果,大大满足了工程对整体强度的要求。
但是,在工程应用中发现,实际荷载往往不只是纵、横向施压,而上述所述各类结构材料往往只能提供纵、横两个方向的加强和支撑,对于来自于斜向的荷载的支撑就会表现出极大的弱点,它们必须通过节点的直角抗剪作用来传递和分散荷载,所以,节点也很容易遭到破坏。
三:发明内容
为解决上述技术问题,本实用新型提供一种塑料拉伸菱形网状结构材料,其能够承载纵向、横向、斜向受力,节点不易被撕裂破坏,受力状态更为合理。
为达到上述目的,本实用新型所采用的技术方案如下:
一种塑料拉伸菱形网状结构材料,包括多个节点,节点与节点之间设有筋带,每个节点连接三个或者六个筋带,使得相邻的四个节点和此节点之间的筋带连接形成菱形单元孔,所述菱形单元孔的锐角顶点连接六个筋带,菱形单元孔的钝角顶点连接三个筋带,所述的网格结构为此多个菱形单元孔辐射延伸组成,相邻两菱形单元孔邻边重合。
本塑料拉伸菱形网状结构由塑料板被横纵向拉伸而成,整个结构一次成形,非焊接或编织而成,此网状结构由规则的菱形单元孔组成,菱形锐角顶点连接六个筋带、钝角顶点连接三个筋带,菱形单元孔交叉排列,能够很好的承载纵向、横向、斜向应力,节点不易被破坏。
四:附图说明
图1为所述网状结构材料一种菱形分布的结构示意图;
图2为所述网状结构材料另一种菱形分布的结构示意图。
五:具体实施方式:
下面结合附图和具体实施例对本实用新型进行详细描述:
如图1、2所示,一种塑料拉伸菱形网状结构材料,包括多个节点,节点之间设有筋带,每个节点连接三个或者六个筋带,使得相邻的四个节点和此节点之间的筋带连接形成菱形单元孔;所述菱形单元孔的锐角近60度,其顶点连接六个筋带,菱形单元的钝角近120度,其顶点连接三个筋带,本网格结构为此多个菱形单元孔组成,相邻两菱形单元邻边重合。根据菱形分布方向不同可有图1和图2两种具体产品方式。
此种菱形网状结构材料比传统的塑料拉伸结构材料能够更有效的分散载荷,因为菱形结构能够承受来自各个方向的载荷,是自然界中蜂巢顶部结构的形状,也是公认的最合理结构之一。
根据上述描述,本专利可通过孔阵列的板材经过纵向、横向拉伸形成的菱形网状结构材料,由于纵向和横向的拉伸倍率不同而有所差异;例如,将孔设计为六角形或者其他可能的形状,对于一定孔径的阵列来讲,纵向和横向的孔间距变化,也会相应影响网状结构材料的最终形状。所以,本专利所述的菱形网状结构材料包括但不限于本专利所阐明的孔阵列以及以此方法制造出的塑料拉伸菱形网状结构材料。
