Embodiment Construction
[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0024] Such as figure 1 and figure 2 As shown, the integral pre-embedded structure of the group double-headed anchor bolts of the present invention includes a plurality of units arranged at intervals, and each unit includes a fixed base 5, a fixed plate 7 located above the fixed base 5, and a set of double-headed anchor bolts. Anchor bolts 3 and double-headed anchor bolts 3 are respectively perpendicular to the fixed base 5 and the fixed plate 7. The two ends of the double-ended anchor bolts 3 are respectively threaded with the fixed base 5 and the fixed plate 7. Located above the fixing plates 7 , each fixing plate 7 is connected into a network structure through the connecting piece 1 . The top of the double-ended anchor bolt 3 is located above the fixed plate 7, that is, the upper threaded part of the double-ended anchor bolt 3 is exposed ...

The invention discloses an integral embedded structure of groups of double-end foundation bolts and a method for constructing the integral embedded structure. The integral embedded structure comprises a plurality of units arranged at intervals. Each unit comprises a fixing base, a fixing plate and a group of double-end foundation bolts, each fixing plate is positioned above the corresponding fixing base, the double-end foundation bolts are respectively perpendicular to the fixing bases and the fixing plates, two ends of each double-end foundation bolt are respectively connected with the corresponding fixing base and the corresponding fixing plate in a threaded manner, the top of each double-end foundation bolt is positioned above the corresponding fixing plate, and the various fixing plates are connected with one another by connecting pieces to form a net structure. The method includes forming holes in the fixing bases and the fixing plates; arranging nuts at the holes; connecting the lower ends of the various double-end foundation bolts with the corresponding nuts in a threaded manner; mounting the fixing plates above the corresponding fixing bases; connecting the upper ends of the various double-end foundation bolts with the corresponding nuts in a threaded manner; connecting the various fixing plates with one another by the connecting pieces to form the net structure. The integral embedded structure and the method have the advantage that the double-end foundation bolt mounting precision can be advantageously guaranteed for ultra-long mechanical equipment.
Description
technical field [0001] The invention relates to an integral pre-embedded structure of group double-headed anchor bolts used in the field of ultra-long mechanical equipment foundation construction, and a construction method of the structure. Background technique [0002] The length of super-long mechanical equipment is greater than 200m, and some are as long as 274m. The installation accuracy of super-long mechanical equipment is high, which requires the installation accuracy of the anchor bolts used to fix the equipment to be high. The anchor bolts corresponding to some ultra-long mechanical equipment are double-headed anchor bolts with high-strength full-screw rods, which are arranged on a super-large rectangular foundation. This kind of double-ended anchor bolts requires a large number of installations. Generally, several double-ended anchor bolts form a group, and each group is arranged at intervals. The position accuracy requirements of each group of double-headed anch...
