Pull the bolt to pull the screw, use it to pull the knot between the wall and the outer formwork, and bear the side pressure and other loads of the concrete to ensure that the spacing between the inner and outer stencils can meet the design requirements, and also the fulcrum of the formwork and its supporting structure. . Therefore, the arrangement of the pull bolt has a great influence on the integrity, rigidity and strength of the formwork structure. For the bolts, the round steel bolts of the two ends are also used, which are also called the wall bolts.
It is also useful to insert the fixed wedges with the wedge irons at the ends of the flat steel. Because bolts are also a type of railroad accessory, railroad fittings are part of the railroad line, and the rails referred to here include rails, sleepers, joint parts, track beds, anti-climbing equipment, rail stays, and ballasts. As a holistic engineering structure, the track is laid on the roadbed and plays a guiding role in train operation, directly bearing the tremendous pressure of the rolling stock and its load. Under the power of train operation, its various components must have sufficient strength and stability to ensure that the train runs safely, smoothly and uninterruptedly to pull the bolt to the wall at the specified maximum speed.
The tie between the outer formwork, the side pressure of the concrete and other loads, to ensure that the spacing of the inner and outer formwork can meet the design requirements, and also the fulcrum of the formwork and its support structure. Therefore, the arrangement of the pull bolt has a great influence on the integrity, rigidity and strength of the formwork structure. Manufacturers and customers discuss the use of high quality hexagon socket bolts to produce wire.
On the other hand, the manufacturer must remember to take the produced natural hexagon socket bolts for hardening, and must require the hardened factory to reach the indicated hardness index. Customers are required to use the corresponding tools properly when using them. They should not use unreasonable tools to make hexagon socket bolts for convenience. Also, let's talk to the customer. When using the hexagon socket bolt, you don't need to use too much force. Grasping the balance of strength is fine. M2.5 hex socket bolts should withstand a torque of more than 2N.m under normal conditions. Therefore, it is necessary to adjust this strength to the right, not too much power.
