Latest company news about Roof Sheet Machine Operate Skills

For this reason, the foundation is carefully inspected before the press is installed, and problems should be dealt with in advance. The contents of the basic inspection include: the external dimensions of the foundation, the level of the foundation surface, the center line, the elevation, the center distance of the anchor bolt holes, and whether they meet the requirements of the design and construction codes. The formwork around the foundation, the wooden box with anchor bolt holes, and water accumulation should be cleaned. For the smooth foundation surface within the range of secondary grouting, many small round pits (ie shovel pits) should be drilled with steel brazing, so that during the second grouting, the original concrete surface of the newly grouted concrete and the anchor bolt holes or the The original base surface is firmly joined to ensure the quality of the grouting.
In the process of inspection, if the non-conformity is found, the fully automatic tile pressing machine shall deal with it. Under normal circumstances, the foundation is more likely to produce directional problems such as non-conformity in elevation and offset of anchor bolt position. These directional problems should be dealt with in time. When the foundation elevation does not match, when the locality is too high, you can use shovel to shovel low. If it is too low, you can shovel the original foundation surface into a sleeping surface. After rinsing with water, refill the concrete. When the center deviation of the foundation is too large, you can consider changing the position of the anchor bolts to adjust. If the individual deviation of the embedded anchor bolts is very small, the bolts can be burnt red by gas welding and then knocked to the correct position. If the deviation is too large, the larger bolts can be chiseled to a certain depth around it and cut It is required that the size of the lap weld be welded on the previous section, and adopt reinforcement measures.
