Spring suspension clip

Abstract

A spring suspension clip configured to suspend a threaded rod member comprises a helical body with an upper end and a lower end, and a clipping section defined as the helical body. Then the clipping section is configured to conform to a threaded section of the threaded rod member to flexibly suspend the by two outward extensions into a space which is drilled and positioned within a section of rock which is to be grouted.

Claims

1. A spring suspension clip for maintaining a space around a threaded rod in a predetermined position in a space in a rock defined by a boundary and to be filled with grout, comprising: a) a helix body; b) a head compressor; and c) a tail compressor; wherein said helix body has a head end; wherein said helix body has a tail end; wherein said helix body has a longitudinal axis; wherein said helix body is steadily threaded onto said threaded rod; and wherein said head compressor extends axially, downwardly, and outwardly compressible relative to the longitudinal axis of the helix body from said head end of said helix body and said tail compressor extends axially, downwardly, and outwardly compressible relative to the longitudinal axis of the helix body from said tail end of said helix body and said head compressor and said tail compressor are substantially diametrically opposite in position to each other on the helix body, so as to allow said head compressor and said tail compressor to compress against, and grab, the boundary of the space in the rock to thereby maintain the space around, and suspend, the threaded rod in the predetermined position in the space in the rock to be filled with the grout.

2. The spring suspension clip of claim 1, wherein said helix body has a width; wherein said helix body has a length; and wherein said width of said helix body is identical along said length of said helix body.

3. The spring suspension clip of claim 1, wherein the threaded rod has a threaded section; and wherein said helix body conforms to the threaded section of the threaded rod so as to allow the helix body to thread onto the threaded section of the threaded rod.

4. The spring suspension clip of claim 1, wherein the threaded rod has a height; and wherein said helix body is rotatably along the threaded section of the threaded rod so as to adjust the height of the threaded rod.

DETAILED DESCRIPTION OF THE INVENTION

(5) FIG. 1 exemplarily illustrates a front perspective view of the spring suspension clip 100. The spring suspension clip 100 is configured to suspend a threaded rod member 105, where the spring suspension clip 100 comprises a helical body 101 with an upper end 101a and a lower end 101b. Then the clipping section 102 is defined as the helical body 101 is configured to conform to a threaded section 109 of the threaded rod member 105 to flexibly suspend the threaded rod member 105 within a space 104 which is drilled and positioned within a section of rock 106 which is to be grouted, as shown in FIG. 2. In an embodiment, the threaded rod member 105 is, for example, of an R32 grade threaded rod.

(6) FIG. 2A illustrates a front perspective view, showing the spring suspension clip 100 used to suspend a threaded rod member 105 which is positioned inside a space 104, and FIG. 2B illustrates an enlarged view of the portion marked A in FIG. 2A. In an embodiment, the grout 107 is filled around the space 104 after suspending the threaded rod member 105 in a predefined position within the space 104, and the grout 107 is allowed to set around the space 104. In an embodiment, an opposing end of threaded rod member 105 is attached to a driver 103 of a rock bolter 108, as shown in FIG. 2A.

(7) A user first positions the driver 103 which is connected to a rock bolter 108 in alignment with the space 104, then the user connects the spring suspension clip 100 at the top end of the threaded rod member 105, and the threaded rod member 105 and the spring suspension clip 100 are inserted into the space 104. Now the threaded rod member 105 is threadably joined with the spring suspension clip 100 at a predetermined height as set by the user by rotating the spring suspension clip 100 along the threaded section 109 of the threaded rod member 105 as shown in FIG. 3. Now the user fills section of rock 106 around the space 104 with the grout 107 to set with the threaded rod member 105 positioned inside the space 104. The spring suspension clip 100 effectively grabs the threaded section 109 of the threaded rod member 105 and the two outwardly tailpieces will grab the sidewall 104a which defines the space 104 as shown in FIG. 2B. The spring suspension clip 100 is very clip to install, and can easily fit through the mechanical sleeve of rock bolter 108 carrousel. The helix body 101 has an upper or head end and a lower or tail end. The two outwardly tailpieces are called head and tail compressors. The head compressor extends axially, downwardly, and outwardly compressible from the head end of the helix body 101 and the tail compressor extends axially, downwardly, and outwardly compressible from the tail end of the helix body 101.

(8) FIG. 3 illustrates a partial sectional view of the joint between the spring suspension clip 100 and the threaded rod member 105. The partial sectional view in FIG. 3, shows how the threaded section 109 of the threaded rod member 105 is conformed within the helical body 101 of the spring suspension clip 100. In an embodiment, the height of the suspension of the threaded rod member 105 can also be adjusted by rotating the spring suspension clip 100 along the threaded section 109 of the threaded rod member 105.
