Abstract

本发明涉及一种用于板状件连接的抗剪切力螺栓。本发明的新型抗剪切力螺栓通过具有中心通孔的台阶型回转体结构、柔性垫圈以及刚性垫圈，可在同时受轴向压力和径向剪切力的条件下工作，其抗剪切能力远远高于传统的抗剪切力螺栓。

Description

一种用于板状件连接的抗剪切力螺栓
技术领域
本发明属于机械技术领域，涉及一种新型抗剪切螺栓，特别是一种用于板状件连接的抗剪切力螺栓。
背景技术
常规的抗剪螺栓受力状态基本都是受拉力剪切力共同作用。受力体5受到轴向螺栓施加的压力，以及板状件对受力体5施加的径向剪切力。
发明内容
本发明的目的是：从材料力学分析来看，螺栓(材料)在受轴向压力的时候，其抗剪性能是会大大提高的；设计一种新型的抗剪切力螺栓，此螺栓的抗剪切能力高于同直径的传统抗剪切螺栓。
本发明的技术方案是：
本发明提供了一种用于板状件连接的抗剪切力螺栓，所述的板状件至少为两个，所述的板状件3，4具有通孔，所述的螺栓1包括螺帽和螺杆；受力体5为具有中心通孔的台阶型回转体结构，所述的受力体5贯穿设置在被连接的板状件的通孔中；螺杆依次穿过柔性垫圈2、受力体的中心通孔、刚性垫圈6后与螺母7螺纹连接；柔性垫圈2套装在所述的台阶型回转体结构小端上；所述的柔性垫圈被夹紧在螺帽和板状件之间，所述的刚性垫圈6被夹紧在螺母7与受力体5的台阶型回转体结构大端之间。
本发明中可以通过调整垫圈厚度，调节板状件之间的贴合压力。
板状件不局限于两件。
本发明的有益效果是：
本发明的新型抗剪螺栓可在同时受压力和剪切力的条件下工作，其抗剪能力远远高于传统的抗剪螺栓。
附图说明
图1是本发明的结构示意图；
其中：1-螺栓、2-柔性垫圈、3-第一板状件、4-第二板状件、5-受力体、6-刚性垫圈、7-螺母。
具体实施方式
下面对本发明的具体实施方式做进一步详细说明：
请参阅图1，提供了一种用于板状件连接的抗剪切力螺栓，所述的板状件至少为两个，所述的板状件3，4具有通孔，所述的螺栓1包括螺帽和螺杆；受力体5为具有中心通孔的台阶型回转体结构，所述的受力体5贯穿设置在被连接的板状件的通孔中；螺杆依次穿过柔性垫圈2、受力体的中心通孔、刚性垫圈6后与螺母7螺纹连接；柔性垫圈2套装在所述的台阶型回转体结构小端上；所述的柔性垫圈被夹紧在螺帽和板状件之间，所述的刚性垫圈6被夹紧在螺母7与受力体5的台阶型回转体结构大端之间。
本发明中可以通过调整垫圈厚度，调节板状件之间的贴合压力。
板状件不局限于两件。
