The body bolts are indispensable everywhere in life, the street lights erected on the road, the beautiful billboards at night, the flagpoles standing on the majesty, and the fixing of the body bolts at the bus stop signs. The role of the body bolts must not be despised. How is the body bolt so fierce? Let’s talk about the machining process of the body bolts. The body bolts are machined to the lathe wire, which requires an average of the thread, and the Carriage Bolt Manufacturer thread length must match the design criteria. The pallets and stiffening anchor plates in the body bolts are usually welded by artificial arc welding. The welds required for welding here are on average full and cannot have any pores and dry tumors. The size of the weld must be determined by the design request. The body bolts are inspected by the data clerk and then submitted to the quality inspectors for further inspection. The acceptance items are mainly to check the specifications and dimensions of the body bolts and the length of the thread buckles to see if it can meet the original design request and wait until the acceptance is passed. It is necessary to stop the archiving work, the archiving work should be registered according to the specification code, and the logo should be attached.

 

The street lights on the road, the station sign and so on under each steel column have body bolts and the base platform are connected together. In order to ensure the accuracy of the body bolt device, a smooth stop for the steel construction device. Before the construction device, the corresponding positions of the body bolts are fixed by bolt fixing frames. The body bolt fixing frames are made of steel plates of 6 mm and 10 mm thickness and 15 mm thick bamboo veneers. After the erection of the base platform template is completed, the body bolt group is placed into the root bottom according to the relative position, and then the bolt fixing frame and the base scaffold are tightly fixed. The time of the inspection requires the theodolite to correct the position of the body bolt. And welded with a diameter of 14 steel and body bolts into a well-shaped frame, supported on the template. The bottom of the bolt is supported by a 16-diameter steel bar and welded to the base backing reinforcement of the cap. The purpose of this is to prevent the body bolt from moving and not sinking. In the process of concrete pouring, the average and symmetrical feeding should be carried out around the roots, and try to prevent the position of the body bolts from changing due to the unevenness of the blanking. At the time of construction, the inspectors should monitor the position and elevation of the body bolts at any time. If it is found that the position of the body bolts is shifted, the adjustment should be stopped in time.
