Description

一种连续FRP复合纤维桁架抗剪切连接件
技术领域
本发明属于剪切连接件技术领域，更具体的说是涉及一种连续FRP复合纤维桁架抗剪切连接件。
背景技术
预制混凝土夹芯板是指保温夹芯板，通常在机构，商业和轻工业建筑中用作外墙或承重构件。这种墙由结构性的外墙、保温材料和剪切连接件组成。剪切连接件用于在混凝土和混凝土之间传递水平剪切力，提高墙体刚性。传统剪力连接件包括钢网，钢连接件，而钢和混凝土连接器的低热阻使预制混凝土夹芯板保温效率低下。
因此，如何提供一种连续FRP复合纤维桁架抗剪切连接件是本领域技术人员亟需解决的问题。
发明内容
有鉴于此，本发明提供了一种连续FRP复合纤维桁架抗剪切连接件，满足墙体刚性要求，并能够切断热桥连接，从而大大提高预制混凝土夹心板的保热效率。
为了实现上述目的，本发明采用如下技术方案：
一种连续FRP复合纤维桁架抗剪切连接件，包括两个折线段一和多个折线段二，多个所述折线段二依次收尾相连，两个所述折线段一分别连接在第一个所述折线段二的首端，最后一个所述折线段二的尾端；相邻所述折线段二间的夹角范围为20°～140°。
优选的，所述折线段一与相连的所述折线段二间的夹角范围为20°～140°。
优选的，所述折线段一的长度为所述折线段二的长度的1/4。
优选的，R>1.5d，其中R代表两折线段二连接处的弯曲半径，d代表折线段二的长度。
优选的，两个所述折线段一与多个所述折线段二一体成型。
优选的，两个所述折线段一与多个所述折线段二均采用复合纤维材料制作而成。
优选的，复合纤维材料包括玻璃纤维、碳纤维或玄武岩纤维中的一种。
优选的，两个所述折线段一与多个所述折线段二的表面均经过喷砂、螺纹或模压肋处理。
优选的，外墙内设置有保温材料，多个所述折线段二均贯穿所述保温材料，折线段二间的连接处以及折线段二与折线段一的连接处均位于所述外墙内；折线段一的两端点均穿插在所述保温材料内。
本发明的有益效果在于：
本发明能够切断热桥连接，从而大大提高预制混凝土夹心板的保热效率；有利于提高预制混凝土夹芯板的抗剪切强度，从而提高预制混凝土夹芯板的结构性能；并且本发明密度低，能够降低预制混凝土夹芯板整体重量。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据提供的附图获得其他的附图。
图1附图为本发明的结构示意图。
图2附图为带有连续FRP复合纤维桁架抗剪切连接件的预制混凝土夹心板的结构示意图。
其中，图中：
1-折线段一；2-折线段二；3-外墙；4-保温材料。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅附图1，本发明提供了一种连续FRP复合纤维桁架抗剪切连接件，包括两个折线段一1和多个折线段二2，多个折线段二2依次收尾相连，两个折线段一1分别连接在第一个折线段二2的首端，最后一个折线段二的尾端；相邻折线段二2间的夹角范围为20°～140°，优选为90°。夹角的角度越小提供给外墙3的刚性越高，90度时是刚度和材料节约的一个平衡点。
本实施例中，折线段一1与相连的折线段二2间的夹角范围为20°～140°，优选为90°。
本实施例中，折线段一1的长度为折线段二2的长度的1/4，长度选择保证折线一能够嵌入外墙3和保温材料4内。
本实施例中，R>1.5d，其中R代表两折线段二连接处的弯曲半径，d代表折线段二的长度。
本实施例中，两个折线段一1与多个折线段二2一体成型。
本实施例中，两个折线段一1与多个折线段二2均采用复合纤维材料制作而成。
本实施例中，复合纤维材料包括玻璃纤维、碳纤维或玄武岩纤维中的一种，也可以为其他材料，相对于钢连接件价格低廉，能够降低生产成本。
本实施例中，两个折线段一1与多个折线段二2的表面均经过喷砂、螺纹或模压肋处理，也可以采用其他处理方式，目的在于增大连续FRP复合纤维桁架抗剪切连接件与保温材料4以及外墙3间的摩擦力，从而增强连接的牢固度。
参阅附图2，外墙3内设置有保温材料4，多个折线段二2均贯穿保温材料4，折线段二2间的连接处以及折线段二2与折线段一1的连接处均位于外墙3内；折线段一1的两端点均穿插在保温材料4内，从而能够大大增强连续FRP复合纤维桁架抗剪切连接件安装的牢固度。
本发明热传递性能低，能够切断热桥连接，从而大大提高预制混凝土夹心板的保热效率；有利于提高预制混凝土夹芯板的抗剪切强度，从而提高预制混凝土夹芯板的结构性能；并且本发明密度低，能够降低预制混凝土夹芯板整体重量；另外本发明材料价格低廉，能够大大节省生产成本。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。对于实施例公开的装置而言，由于其与实施例公开的方法相对应，所以描述的比较简单，相关之处参见方法部分说明即可。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本发明。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
