本实用新型涉及结构连接件保护装置，具体为一种简易分体式地脚螺栓保护帽。 The utility model relates to a protective device for structural connectors, in particular to a simple split type anchor bolt protective cap.
背景技术 Background technique
地脚螺栓的作用就是将机械、设备、大型结构或构件固定在地面上用的。因为它具有较强的稳固性，所以经常看到它应用在铁路、公路、桥梁、矿山、电厂、电力和通信杆塔、塔吊、锅炉钢结构、大跨度钢结构以及大型建筑等上面。地脚螺栓的制作材料一般采用Q235碳素结构钢，也有采用Q345低合金高强度结构钢来制作。 The role of anchor bolts is to fix machinery, equipment, large structures or components to the ground. Because of its strong stability, it is often seen in railways, highways, bridges, mines, power plants, power and communication towers, tower cranes, boiler steel structures, long-span steel structures, and large buildings. Anchor bolts are generally made of Q235 carbon structural steel, and some are made of Q345 low-alloy high-strength structural steel.
地脚螺栓大致由露头段和锚固段两部分组成。露头段，即露出于基础顶面的部分，包括螺栓、螺母和垫圈三部分。锚固段即埋入基础或地下部分。根据锚固段螺栓底部形状和构造，地脚螺栓可以分为L型地脚螺栓、J型地脚螺栓、棘爪型地脚螺栓和T型地脚螺栓（即带螺栓连接锚板的地脚螺栓和带焊接锚板的地脚螺栓）等。 The anchor bolt is roughly composed of two parts: the outcrop section and the anchor section. The outcrop section, that is, the part exposed on the top surface of the foundation, includes three parts: bolts, nuts and washers. The anchorage section is buried in the foundation or underground part. According to the shape and structure of the anchor bolt bottom, anchor bolts can be divided into L-type anchor bolts, J-type anchor bolts, pawl-type anchor bolts and T-type anchor bolts (that is, anchor bolts with bolts to connect anchor plates) and anchor bolts with welded anchor plates), etc.
为了确保地脚螺栓与基础的之间足够的锚固力，防止地脚螺栓被拔出而导致的设备或结构松动、移位或倾覆，地脚螺栓的安装有埋置深度以及角度的要求。根据地脚螺栓原材料强度、地脚螺栓直径大小、地脚螺栓底部类型、以及地脚螺栓锚固基础材料的类型和强度，地脚螺栓具有不同的露头段和锚固段长度。常用的地脚螺栓露头段长度为25mm~440mm，锚固段长度为60mm~4900mm。 In order to ensure sufficient anchoring force between the anchor bolts and the foundation, and prevent the equipment or structure from loosening, shifting or overturning caused by the anchor bolts being pulled out, the installation of the anchor bolts has requirements for the depth and angle of embedding. According to the strength of the raw material of the anchor bolts, the diameter of the anchor bolts, the type of the bottom of the anchor bolts, and the type and strength of the anchoring base material of the anchor bolts, the anchor bolts have different lengths of outcropping and anchoring sections. The length of the commonly used anchor bolt outcrop section is 25mm~440mm, and the length of the anchor section is 60mm~4900mm.
作为结构或设备的重要锚固构件，地脚螺栓的设计使用寿命一般都非常长，往往需要达到几十年。但是，地脚螺栓在安装后，往往由于环境作用，地脚螺栓露头段裸露在空气中，不可避免的产生腐蚀，尤其在海边、山上等复杂环境中，腐蚀破坏力更为严重，随着时间延长，就会对地脚螺栓本身强度和稳固性造成很大的影响，给被固定的设备带来安全隐患。 As an important anchoring component of structures or equipment, the designed service life of anchor bolts is generally very long, often reaching decades. However, after the anchor bolts are installed, often due to environmental effects, the exposed sections of the anchor bolts are exposed in the air, and corrosion is inevitable. Especially in complex environments such as seaside and mountains, the corrosion damage is more serious. If it is extended, it will have a great impact on the strength and stability of the anchor bolt itself, and bring safety hazards to the fixed equipment.
因此，有必要对地脚螺栓设计一种保护帽。 Therefore, it is necessary to design a protective cap for the anchor bolts.
