The connector (100) system and method comprises and makes use of the housing (10) and the tendon (200).

Fasteners and related systems according to the invention include a collet body having a first part of a two part anti-rotation arrangement and a cylinder body having a second part of the two part anti-rotation arrangement wherein the collet body and the cylinder body are mateably axially translatable with respect to each other, and have the same or similar outer diameter in some embodiments or not in others. A threaded member rotationally engages the collet body and compressively contacts the cylinder body during operation of the fastener to creating a clamping effect. Rotational interference between the first and second parts of the anti-rotation arrangement preferably occurs at sectional face portions of at least the collet body. Resistance to induced rotation of the cylinder body relative to a work piece rotation of the threaded member is preferably provided by a tool engaging a tool interface present on the cylinder body.

A double connector for butt-joining two components includes two connector components which can be pushed together as far as a locked assembly position and which each have an spreadable first end portion for inserting into a hole of a component, and a second end portion for spreading the first end portion of the other connector component in each case in the assembly position and at least one locking portion for interlocking the two connector components in the assembly position.

Disclosed here is a method for arranging at least one composite element at a component. The composite element includes a sleeve element and an insert element. The method involves: arranging the sleeve element in a bore of the component; connecting the sleeve element and the insert element so that a composite element is formed; inserting an engagement apparatus in the composite element, wherein the engagement apparatus aligns and/or assembles the sleeve element and the insert element to each other. Also disclosed here is use of an engagement apparatus and at least one composite element for arranging the composite element at a component. The at least one composite element includes a sleeve element and an insert element. The engagement apparatus aligns and/or assembles the sleeve element and the insert element to each other.

A method and system of affixing a plaque to a solid surface is provided. The method includes the steps of providing at least one opening in a face of the solid surface and inserting a plaque support into the at least one opening. The plaque support includes a body defining a passageway therethrough and having a first end and a second end. The first end has a flange portion. Further, at least one outer tab member extends radially outward toward the first end and at least one inner tab member extends radially inward toward the second end. The outer tab member engages the solid surface upon insertion of the plaque support into the at least one opening. The method and system further include providing the plaque with at least one installation fastener. The at least one installation fastener is inserted into the passageway of the plaque support, such that the at least one inner tab member engages the at least one installation fastener.

A fastener for securing a door hinge to a wooden jamb. The fastener includes an anchor and a screw. The anchor having a wall enclosing a central inner void. The central inner void can extend along the length of the anchor. The screw having a head, a shaft, and a tip. The shaft extends between the tapered head and the tip and can have a threaded portion that extends along the length of the shaft. The screw can be configured to concentrically insert into the central inner void of the anchor causing expansion of the wall of the anchor. The tapered head of the screw can fit onto an aperture of the hinge joint. The top surface of the tapered head can have a grove for driving the screw using a screwdriver.

An expansion connector including an expandable casing, a pushing member, a compression spring, and a connecting rod. The expandable casing includes an expansion end and is in the shape of a hollow cylindrical tube provided with an axial hole and an inner wall defining the axial hole. The connecting rod includes a first end, a second end, and a stopper disposed between the first end and the second end. The pushing member, the compression spring and the connecting rod are disposed in the expandable casing; the expansion end is expandable radially outwards with respect to the axial hole; the pushing member is disposed in the axial hole and abuts against the expansion end; the pushing member includes a first male thread, and the inner wall of the expansion end includes a first female thread corresponding to the first male thread.

An Anchor Bolt Setting (ABS) system has a bolt cap adapted to securely hold an anchor bolt vertically by an upper threaded end, with the anchor bolt suspended below the bolt cap, and an adapter having a first interface shaped to engage an edge of a foundation form for concrete, a substantially planar portion extending over the foundation form from the edge, and a second interface in the planar portion shaped to engage and suspend the bolt cap, with the anchor bolt suspended downward. The anchor bolt is threaded into the bolt cap, the adapter is engaged to the edge of the foundation form extending horizontally over the foundation form, the bolt cap with the anchor bolt engaged is engaged to the second interface of the adapter, presenting the anchor bolt downward into the foundation form, and uncured concrete is poured into the foundation form, enveloping the anchor bolt.

The present disclosure describes an anchor device for receiving and securing a shaft thereto. The device includes an outer housing within which a jaw assembly is secured. The outer housing of the device may in turn be secured to or within a support structure such as a building component. Jaw components of the jaw assembly may be threaded. Furthermore, the jaw assembly has at least two configurations. In a first configuration, at least one jaw component is positioned away from a central shaft axis against the biasing force of a biasing member. A removable or reconfigurable holding member or stop member selectively secures the at least one jaw component in this position. A second configuration is the result of the holding member being reconfigured by the inserted shaft. The shaft triggers movement of the at least one jaw component toward the central shaft axis and into contact with the shaft.
