What are the traditional anchor bolt inspection and anchorage methods? Please ask the master to teach me, please, 3Q

the position is accurate and meets the installation requirements of machinery and equipment. Due to the factors of machinery and equipment itself, the accuracy of the position of the anchor bolt is required, and the allowable error is generally only within millimeters. Therefore, measures must be taken to ensure it during construction. The requirements for the position of anchor bolts are generally as follows: the deviation of plane position should not exceed 2-5 mm; The top elevation error of screw inspection shall not exceed ~ 12mm, and negative error is not allowed. Before 193s, when the machine foundation was made of masonry, the machine was fixed to the foundation by wedging anchor bolts. The buried part of the anchor butterfly bolt is made into a square frustum or a circular frustum, and some of them are also made with some barbs on the side. In this way, the depth of the anchor bolt buried in the foundation is larger. After the 193s, when concrete and reinforced concrete equipment foundations were adopted, the anchoring method was changed into the binding of anchor bolts with concrete and the use of anchor plates or other forms. There are basically three traditional anchoring methods for anchor bolt inspection: embedded bolt method, which is mainly used for anchoring bolts such as hook bolt inspection, claw bolt inspection and anchor plate bolt inspection. The anchor plate method is preset, and the anchor is anchored by thousand-headed bolts, counter-screwed bolts and screwed bolts. The reserved hole method is used for anchoring some dead bolts such as hook bolts. The embedded bolt method is to fix the anchor bolt in the position specified in the design with the fixing frame first, and then pour the foundation concrete to anchor the anchor bolt. The embedded bolt method is mainly used for anchoring hook bolts, claw bolts and drilling plate bolts when they are waiting for screw inspection.
