Problems solved by technology

But the defect in this anchor bolt device is: at first, nut box and nut are arranged separately, in order to realize the circumferential fixation of nut, nut needs to be welded on lower anchor plate, but the stress unevenness of whole lower anchor plate is caused in welding nut or ;Secondly, this will add a welding process, which will increase the cost; again, in order to meet the construction conditions, the plastic sleeve and the anchor bolt need a certain gap, and the entire anchor bolt device is basically filled in concrete. The medium concrete will inevitably squeeze the plastic casing to force the plastic casing to deform so that the anchor bolt and the plastic casing are out of alignment, making it difficult to unscrew the broken anchor bolt for replacement

Embodiment 1

[0024] Embodiment 1, an anchor bolt assembly, see figure 1 As shown, the anchor bolt body 1 is included, and the anchor bolt body 1 is an existing prestressed anchor bolt. The upper end of the anchor bolt body 1 is a cone head end, and the lower end is a flat head end. A rigid sleeve 2, wherein, in this embodiment, the rigid sleeve 2 is a stainless steel pipe, the length of the rigid sleeve 2 is slightly shorter than the length of the anchor bolt main body 1, and the lower end of the anchor bolt main body 1 is threadedly connected with an isolation cap 3, Solid butter is filled between the two ends of the rigid sleeve 2 and the anchor body 1 to realize the sealing between the rigid sleeve 2 and the anchor body 1 . Also, see e.g. image 3 As shown, in this embodiment the isolation cap 3 is a head nut.

Embodiment 2

[0025] Embodiment 2, an anchor bolt assembly, differs from Embodiment 1 in that, as figure 2 As shown, the top end of the anchor bolt body 1 is flat. In this way, it is convenient to clamp the top of the anchor bolt main body 1 to remove the upper half of the anchor bolt main body 1, and then select the rod extractor to take out the lower half of the anchor bolt main body 1.

[0026] For the specific structure of the rod taker, see Figure 9 , including a sheath 8 and a drill bit 81 arranged in the sheath 8, the sheath 8 is a steel sheath, and the diameter of the lower end of the sheath is slightly larger than the diameter of the anchor bolt body 1. Insert the sheath 8 into the rigid sleeve 2 and cover the outside of the broken anchor body 1 through the transition fit between the sheath 8 and the anchor body 1 to achieve fixation, and the drill bit 81 extends into the sheath 8 and connects with the broken anchor body 1 The fractured end faces of the broken anchors conflict,...

Embodiment 3

[0027] Embodiment 3, an anchor bolt assembly, differs from Embodiment 1 in that, as image 3 As shown, the anchor bolt main body 1 is covered with a support ring 9 , and the diameter of the support ring 9 is smaller than the inner diameter of the rigid casing 2 . In addition, the support ring 9 is a rubber ring, and the number of the rubber rings can be 1, 2 or 3, which are respectively located at the upper part, the middle part and the lower part of the main body of the anchor bolt.

Abstract

The invention discloses an anchor bolt assembly. According to the technical scheme, the anchor bolt assembly comprises an anchor bolt body which is sleeved with a rigid casing pipe, the two ends of the rigid casing pipe are in sealed connection with the anchor bolt body, and the bottom end of the anchor bolt body is in threaded connection with an integral isolation cap. The assembly has the beneficial effects of being convenient to replace and low in cost.

Description

technical field [0001] The invention relates to the technical field of building foundations and fan foundations, in particular to an anchor bolt assembly. Background technique [0002] At present, the racks and towers of large or very large equipment, including wind generators, wind turbines, power line street lighting and signaling devices, bridge supports, commercial signs, highway signboards, ski lifts and other buildings are all constructed on site. Concrete foundation support. [0003] The anchor bolt mainly bears the cyclic load from the upper fan tower, plus the prestress imposed by itself, the working state is complicated, easy to damage, and the prestress level cannot be maintained for a long time. The anchor bolt itself has a high-strength prestress, and the tension or pressure on the anchor bolt caused by the tilting tendency of the wind turbine tower. With the continuous application of this load, the prestress of the anchor bolt itself is also reduced, and the ...
