1 Construction technology of large equipment foundation anchor bolts
(1) According to the construction drawings of the foundation bolts of the equipment, the upper and lower layers of the distance are sampled.
(2) When the foundation cushion is constructed, the embedded parts of the fixed poles of the fixed distance fixed plate are pre-buried.
(3) When installing the anchor bolt holder, first solder the pole to the embedded part, and then weld the scissors between the poles.
(4) According to the design elevation of the anchor bolts, copy the installation elevation of the upper and lower fixed distance samples.
(5) Weld the support of the fixed distance model on the fixed pole and install the upper and lower fixed distance samples.
(6) Adjust the upper and lower fixed distance samples according to the equipment basic control axis until the equipment basic control axis and the fixed distance template axis match, and then fix the fixed distance template on the support.
(7) Install the anchor bolts on the fixed distance template. First measure the height of the anchor bolt with the water level gauge, and control the deviation of the anchor bolt height between 0 and 10mm, then adjust the center distance, diagonal line and chord length between the anchor bolts, and adjust the deviation to within 2mm. .
(8) Spot welding the bottom of the anchor bolt to the lower layer.
2 Steel structure column anchor bolt construction technology (1) According to the steel structure column anchor bolt diameter and spacing to make adjustable anchor clamp.
(2) Install the anchor bolts on the adjustable anchor clamps, and adjust the spacing between the anchor bolts according to the pitch of the anchor bolts until the deviation value is controlled within 2mm.
(3) Adjust the anchor clamp according to the control axis of the steel structure column until the center line of the anchor clamp matches the axis of the steel structure.
(4) Spot welding the bottom of the anchor bolt to the concrete column reinforcement.
During the foundation construction of the engineering equipment, the above management and construction techniques were used to solve various construction difficulties, ensure the construction period, ensure the smooth construction of the installation project, improve the technical level of the construction, and provide experience for similar projects. method.
