Insert designed to be fitted on a support, including a body extending along a longitudinal axis and a base including at least one plate extending along a base plane, at least one through hole oriented along an orientation axis perpendicular to the base plane being formed in said at least one plate, at least one protuberance being formed on a first surface of said at least one plate and forming a hollow on a second surface of said at least one plate.

To provide a post-installed anchor capable of being used repeatedly and being easily removed and recovered.

A post-installed anchor to be inserted and fixed in an anchor insertion hole formed in a structure includes: a cylindrical anchor body; expandable pieces obtained by dividing the tip side of the anchor body into a plurality of pieces by a plurality of slits 16 which are formed on the tip side, leaving equal intervals in a circumferential direction and extending in the axial direction of the anchor body, the expandable pieces each having a plate-like part whose surface is formed into a flat surface and which has spring force, a fixing part formed at the tip of the expandable piece and having a larger thickness than that of the plate-like part, and an inclined part whose inner surface is gradually inclined inward toward the tip of the expandable piece; a female screw formed in an inner surface of an unexpandable part side of the anchor body; and a male screw body formed into a substantially columnar shape that can be inserted into the anchor body, having a wedge part with a truncated conical shape at its tip, having a male screw screwed with a female screw formed in the anchor body at its rear end side, and having a rotary tool engagement part at its rear end surface. The male screw body is advanced with the male screw of the male screw body screwed with the female screw of the anchor body to make the truncated conical shaped wedge part at the tip of the male screw body abut against the inclined part formed so that the inner surface thereof is gradually inclined inward toward the tip side of the expandable piece to expand the expandable piece by wedge action, pressing the outer surface of the fixing part against the hole wall of the anchor insertion hole, which thereby fixes the post-installed anchor in the anchor insertion hole, and the male screw body is retracted to close the expanded expandable piece by spring force of the plate-like part of the expandable piece for recovery and reuse.

The invention relates to a dowel for arranging in lightweight building boards, wherein a lightweight building board has a first cover layer and a second cover layer made of compact, pressure-resistant material and, arranged between the cover layers, a core layer made of material having a lower density than the cover layers, comprising a first dowel part and a second dowel part, wherein the first and the second dowel part are designed to be displaceable relative to one another, in which dowel the first dowel part and the second dowel part each have at least two fingers which extend parallel to a longitudinal direction of the dowel, wherein, in the plugged-together state of the first and second dowel part, the fingers of the first dowel part and the fingers of the second dowel part inter-engage at least in certain portions.

A fastening system for a metallic cellular shipping container floor includes a potted insert with a body disposed between a top flange at one end and a bottom flange at another end. The body defines a channel from the top flange leading towards the bottom flange and has a depth not exceeding a distance from the top flange to the bottom flange. The system also includes a hole formed in a panel of a metallic cellular shipping container floor with a depth identical to or greater than a distance from a top portion of the top flange to a bottom portion of the bottom flange. Finally, the system includes a self-tapping screw disposed within the channel of the potted insert, and including a threaded shaft with tip at a distal end of the shaft, and a screw head at a proximal end of the shaft.

Injection mortar for anchoring a fastener containing a chemical composition that can cure in a curing process, and means for initiating the curing process characterized in that the chemical composition cures when irradiated with electromagnetic radiation, the means for initiating the curing process is formed by a radiation source for electromagnetic radiation, and the radiation source is placed within the anchoring zone.

The present invention relates to a device and a method associated with the device. With respect to the device, it is a structural connector for fastening structural components in insulated concrete formwork (ICF). The structural connector consists of a double threaded cylinder bolt assembly that aligns through openings in the ICF wall. One end of the cylinder bolt assembly embeds into the cavity of the ICF wall where openings in the cylinder bolt assembly receive concrete and reinforcement bars. The other end of the cylinder bolt assembly is threaded to receive a double threaded washer head bolt. The cylinder bolt assembly is used to mount ledger boards, floor joist hangers and roof truss connectors to the ICF wall, locking them together acting as one unit in withstanding bending and uplift loads imposed by large forces such as floor and roof truss systems.

A metal joint adapted to be fitted into a hole formed in a building component and fixed to the hole with an adhesive includes: a small diameter portion having an elongated shape and an outer diameter smaller than an inner diameter of the hole; and two large diameter portions fixed to the small diameter portion individually at two locations spaced apart from each other in a longitudinal direction of the small diameter portion, each large diameter portion having an outer diameter corresponding to the inner diameter of the hole. Furthermore, irregularities are formed on an outer peripheral surface of the small diameter portion in a section between the two large diameter portions.

A cured concrete and stone bore working tool and method of forming radially oriented discontinuities in a bore or perforation formed in a cured concrete or stone material such that, after use or application of the tool, the perforation formed in the cured concrete or stone material is configured to provide a non-planar adhesive interface and isolate a properly sized anchor or fastener from direct contact with the wall of the bore. Fasteners or anchors adhesively secured in bores previously treated with the bore treating tool exhibit improved creep failure performance as compared to fasteners adhesively secured to untreated bores.

A fastener-receiving insert system includes a fastener-receiving insert having a proximal end and a distal end and at least one adhesive-dispensing chamber adjacent to the distal end of the insert, containing at least one part of an adhesive material within a chamber wall. The fastener-receiving insert system further includes a puncturing device operably engaged with and configured to puncture the chamber wall to release the at least one part of the adhesive material around the fastener-receiving insert.

A ballistic resistant fastener having a ballistic resistant face plate includes a plurality of layers of aramid synthetic fibers or carbon nanotubes, a plug body having a threaded body bore extending into the body, a helical thread insert within the plug body, a bolt engaging the helical thread insert, and a bottom cup having a cup sidewall attached to the body.
