Description

Foundation bolt

Technical Field

The utility model relates to a bolt, be used for fixing the subaerial rag bolt of the base of equipment specifically to say so.

Background

The anchor bolts are bolts connecting the base of the equipment with the ground. At present, traditional rag bolt includes the stand, and the upper portion processing of stand has the external screw thread, and there is gland nut the upper end of stand, and the lower extreme of stand is 90 crooked kink to its one side. When the device is used, the lower end and the bent part of the upright post are embedded into the ground according to the installation position of the device; then, the mounting hole of the base of the equipment is sleeved from the upper end of the corresponding upright column, so that the base of the equipment is abutted against the ground; and finally, screwing the compression nut. Traditional rag bolt is when using, and the base of equipment offsets with ground, and some equipment when installation, its base need be gapped with ground, when using this bolt, need subaerial extra setting up the platform, and the cost is higher. Moreover, when the height of the base and the ground is adjusted, the base needs to be detached first, the height of the platform needs to be changed again, and the operation process is complicated.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a rag bolt, the cost of using this rag bolt is lower, and the process of changing the base height is simple and convenient.

In order to solve the problems, the following technical scheme is provided:

the utility model discloses an rag bolt includes the stand, and the upper portion processing of stand has the external screw thread, and the upper end of stand has gland nut, and the lower extreme of stand is 90 crooked kink to its one side. The nut is characterized in that the section of the upright column between the nut and the bending part is sleeved with a vertically arranged external threaded pipe, a gap is reserved between the outer wall of the upright column and the inner wall of the external threaded pipe, and a gasket is arranged between the compression nut and the upper end face of the external threaded pipe. The upper end of the outer threaded pipe is concentrically and integrally connected with an annular outer boss which extends outwards in the radial direction, and the upper end face of the annular outer boss is flush with the upper end face of the outer threaded pipe.

Wherein, the external thread pipe is provided with a jacking nut.

The outer section of the annular outer boss is in a regular hexagon shape.

By adopting the scheme, the method has the following advantages:

because the utility model discloses an rag bolt states that section stand between nut and kink on the cover be connected with vertical arrangement's external screw thread pipe, gapped between stand outer wall and external screw thread pipe's inner wall, has the gasket between the up end of nut and external screw thread pipe, and the concentric body coupling in upper end of external screw thread pipe has the outer boss of the annular that radially outwards stretches out, and the up end of the outer boss of annular flushes with the up end of external screw thread pipe. When the device is used, a threaded hole is machined in a mounting hole of the device base; then, the external threaded pipe is connected with the mounting hole of the base in a threaded mode, so that the lower end of the external threaded pipe extends out of the bottom of the equipment base; then, according to the installation position of the equipment, the lower end and the bent part of the upright post are embedded into the ground; then, the external thread pipe and the equipment base are sleeved on the upright post together, so that the external thread pipe is abutted against the ground; and finally, placing a gasket at the upper end of the upright column, and screwing a compression nut. This kind of rag bolt utilizes the screw-thread fit of equipment base and external screw thread pipe can be with equipment base and ground separation to need not to set up the platform, greatly reduced use cost. Moreover, the equipment bottom plate is fixed in the circumferential direction; and the clearance between the equipment bottom plate and the ground can be adjusted by turning to the external threaded pipe, so that the operation process is convenient and fast.

Drawings

FIG. 1 is a schematic structural view of the anchor bolt of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in figure 1, the utility model discloses an rag bolt includes stand 4, and the upper portion processing of stand 4 has the external screw thread, and there is gland nut 3 stand 4's upper end, and stand 4's lower extreme is to its one side kink 7 that is 90 crooked the outer threaded tube 1 that the cover is connected with vertical layout on that section stand 4 between nut and kink 7, it is gapped between stand 4 outer wall and the inner wall of outer threaded tube 1, there is gasket 9 between gland nut 3 and the up end of outer threaded tube 1. The upper end of the external threaded pipe 1 is concentrically and integrally connected with an annular outer boss 2 which extends outwards in the radial direction, and the upper end face of the annular outer boss 2 is flush with the upper end face of the external threaded pipe 1.

In order to ensure the strength, the external thread pipe 1 is provided with a jacking nut 6.

In order to facilitate the rotation of the external thread pipe 1, the external section of the annular external boss 2 is in a regular hexagon shape.

When the device is used, a threaded hole is machined in the mounting hole of the device base 5. Then, the male screw pipe 1 is screwed with the mounting hole of the base 5 so that the lower end of the male screw pipe 1 protrudes from the bottom of the base 5, and the top-tightening nut 6 is screwed onto the male screw pipe 1 from the lower end of the male screw pipe. Then, the lower end of the column 4 and the bent portion 7 are buried in the ground 8 according to the installation position of the equipment. Then, the external threaded pipe 1 is fitted over the column 4 together with the equipment base 5, so that the external threaded pipe 1 abuts against the ground 8. And finally, placing a gasket 9 at the upper end of the upright post 4, and screwing the compression nut 3.
