Problems solved by technology

In the first method, due to the large size of the anchor bolts of large-scale equipment, M72, M80, and M100 are generally used, with a length of 3.5 meters and a weight of nearly 200KG. In addition, the limited working space of the external equipment makes it very difficult for the bolts to be lifted and rotated.
In the second method, due to the narrow gap between the equipment and the foundation, it is very difficult to seal the casing, and the seal is not complete due to the influence of the clamp

Embodiment Construction

[0011] Such as figure 1 Shown: a method for fixing T-shaped anchor bolts and sealing the sleeve. First, put the T-shaped anchor bolt 5 into the sleeve, and weld the 6mm-thick circular steel plate 4 to the inner wall of the sleeve 6. The distance from the sleeve 6 is At the 30mm place on the plane, rotate and lift the T-shaped anchor bolt 5 by using the reverse chain, then put the 20mm thick rubber and plastic sponge ring 3 into the T-shaped anchor bolt 5, and place the two semi-circular steel plates 2 with a thickness of 6mm On the ring 3, use bolts to fasten through M16 nuts 1. This method can be used to lift, rotate and fix the T-shaped anchor bolts in advance, and effectively seal the sleeve without affecting the adjustment of the T-shaped bolts, which facilitates the installation of equipment in place, effectively reduces construction personnel, improves equipment installation efficiency, and prevents grouting The material flows into the sleeve. The method can greatly re...

Abstract

The invention relates to a method for fixation of a T-shaped foundation bolt and sleeve sealing. The method is characterized in that first the T-shaped foundation bolt is placed in a sleeve, an annular steel plate is welded to an inner wall of the sleeve, a chain block is utilized to rotate and lift the T-shaped foundation bolt, a circular ring is sleeved with the T-shaped foundation bolt, two semi-circular steel plates are placed on the circular ring and fastened through bolts and nuts, and the circular ring is a rubber and plastic sponge circular ring. The T-shaped foundation bolt can be lifted, rotated and fixed in advance, the sleeve is effectively sealed, adjustment of the T-shaped bolt is not influenced, device installation in position is facilitated, constructors are effectively reduced, device installing efficiency is improved, and a grouting material is prevented from flowing into the sleeve.

Description

technical field [0001] The invention relates to a fixing and sealing method, in particular to a fixing and sleeve sealing method of T-shaped anchor bolts. Background technique [0002] In the installation process of large equipment, T-shaped anchor bolts are widely used, but because a piece of equipment has many anchor bolts to be fastened together, it has always been a very cumbersome item to raise the T-shaped anchor bolts and seal the sleeve. Work. [0003] Traditionally, there have been two ways of dealing with this. 1. After the unfixed anchor bolts and other equipment are in place, lift and rotate the anchor bolts. Finally, fill the sleeve with sand and asphalt to seal it, and then perform secondary grouting for the equipment. 2. Lift and rotate the anchor bolts in advance and fix them with fixtures before placing the equipment in place. After the equipment is adjusted, the sealing sleeve is used for secondary grouting. In the first method, due to the large size of ...
