Full analysis of pre embedded anchor bolts for steel structure factory buildings

In the construction process of Steel structure workshop, the pre embedding of anchor bolts is a crucial foundation link, and its quality directly affects the stability and safety of the entire Steel structure workshop structure.

Firstly, the preparation work before construction is crucial. For steel structure factories, precise design drawings are required to determine the position, specifications, and quantity of anchor bolts. According to the drawings, accurately measure and set out at the construction site, and mark the pre embedded position of each anchor bolt. At the same time, it is necessary to ensure that the construction site is flat and solid, providing good conditions for subsequent operations. In terms of material preparation, the pre embedded anchor bolts of steel structures must meet the material, strength grade and other standards required by the design. High strength bolts are usually used, with clear and undamaged threads and precise length.

Then enter the pre embedded construction phase. Excavate bolt pits at designated locations, with the depth and size determined based on the specifications of the bolts and the design load of the factory building. Generally speaking, the bottom of the pit should be leveled and a layer of fine aggregate concrete should be laid as a cushion layer to ensure the verticality and stability of the bolts. When placing the anchor bolts in the pit, a specialized positioning mold or bracket should be used. These molds or brackets need to have sufficient strength and accuracy to firmly fix the anchor bolts and prevent displacement during the concrete pouring process. For the foundation bolts of steel structure factories, the accuracy of positioning is particularly critical due to their ability to withstand large tensile and shear forces. Even small deviations may cause serious problems during the subsequent use of the factory.

In the concrete pouring process, appropriate pouring techniques should be adopted. Usually, the method of layered pouring and layered vibration is used to ensure that the concrete can evenly fill the gaps around the bolts and tightly bond with them. During the pouring process, close attention should be paid to the position changes of the anchor bolts. If there is displacement, the pouring should be stopped immediately and adjustments should be made. The slump of concrete should also be strictly controlled. If it is too thin, it may cause bolts to sink or shift, while if it is too thick, it is not easy to compact by vibration. For the concrete around the anchor bolts of the Steel structure workshops, special curing is also required to ensure that its strength can grow rapidly and steadily, meeting the requirements of the factory construction schedule.

In addition, quality inspection and control run through the entire pre embedding process. After the bolt installation is completed, check whether its verticality, levelness, spacing and other parameters meet the design standards. Accurate measurements can be made using measuring instruments such as total stations and level gauges. After pouring concrete, it is also necessary to regularly check the exposed length and thread condition of bolts to ensure that they are not contaminated or damaged by concrete. If any problems are found, remedial measures should be taken in a timely manner, such as readjusting the bolt position or repairing the threads.

In short, the pre embedding of foundation bolts for Steel structure workshops is a delicate and important task. Only by carefully preparing before construction, strictly following the specifications during the construction process, and strengthening quality inspection and control, can the quality of pre embedded anchor bolts be ensured, laying a solid foundation for the smooth construction and safe use of steel structure factories in the future. Every step should not be missed, from measurement and laying out to concrete pouring and curing, construction personnel need to have professional skills and a high sense of responsibility to create a stable and reliable steel structure factory foundation.
