Do high strength bolts need attention before installation? What if there is a problem?
Prior to the installation of high-strength bolts, it is necessary to have a detailed understanding of the whole project and mark according to the drawings. It is easy for former workers to forget to check the deformation and coating quality of steel structure items when installing high-strength bolts. Although the high-strength bolt steel members are well produced in the processing plant, they are qualified after inspection. However, in the process of loading and unloading and transportation, the steel paint structure of high-strength bolts will deform or fall off. If we do not deal with it in time before construction, it will seriously affect the quality of steel structure installation.
How to avoid the deformation of high strength bolt steel structure and the coating falling off? What measures should be taken to solve this problem? Let’s talk about how to solve the problem of deformation and coating off of high-strength bolt steel structure.
When large steel structure and high-strength bolt are being assembled in production and installation, appropriate number of lifting points shall be welded according to the specific length of steel structure. The loading and unloading car is also very convenient, and there will be no deformation of steel members and coating falling off. Small steel structure members with high-strength bolts usually need to be packed, and then the steel structure members shall be aligned at the hoisting position with protective measures. When high-strength bolt steel structure members are stressed, appropriate amount of steel structure members shall be padded under the members to adopt protective measures. If the steel structure members with high-strength bolts are loaded, they shall be padded with appropriate number of sleepers under the members.
If it is a small steel structure, it is necessary to lay a layer of bamboo plywood under the components of high-strength bolt steel structure when loading. In the process of transportation, pay attention to the safety speed to prevent the collision between high-strength bolt components. When unloading at the construction site, a certain number of sleepers shall be properly padded under the members according to the steel structure length of high-strength bolts. Only taking the above measures can ensure the quality and safety of high-strength bolts.
