Abstract: The invention disclosed shows a device, method and system for installing threaded masonry anchors. A plate is used to control the rate of axial penetration of the anchor into a masonry structure. An opening in the plate allows engagement of the anchor with the plate. Rotation of the plate is prevented by various means. As the anchor advances and forms threads in the structure, the plate may be used to resist axial forces on the anchor in either axial directions thereby precluding stripping of threads formed in the masonry structure.

Abstract: A temporary anchor for securing part of a structure to the earth includes a tension member made up of at least two complementary shaped parts forming a regular shaped exterior. One or more ribs are formed on the exterior peripheral surface of each part so that it can be engaged within a settable grout material when it is inserted into a borehole formed in the earth. A spacer member is positioned between facing surfaces of the tension member parts and holds them in spaced relation along the length of the parts within the borehole. The spacer member is removable from between the parts when they are anchored in a grout substance so that the parts can then be removed by exerting a pulling force on them.

Abstract: As a masonry or block wall is constructed, plates are placed through the wall between courses. Anchor assemblies are then secured to the ends of the plate and extend downwardly and outwardly at approximately 45.degree. from the vertical and are secured to anchors within the ground. Vertically extending plate portions depend from each end of the plates and engage the faces of the wall and support the wall until it can be braced by the installation of the roof assembly. At this time, the anchor assemblies can be removed and the plate driven outwardly from between the courses with the resultant apertures then being mortared in the usual way.

Abstract: In a composite beam, a connecting element interconnects a concrete slab and a downwardly depending structural steel member. The connecting element is L-shaped having an elongated base member which is secured by one or more fastening elements to the structural steel member and an elongated anchor strap extending angularly from the base member and incorporated into the concrete slab. Supporting webs are secured to and extend between the base member and the anchor strap. The part of the base member encircling the openings through which the fastening elements pass is deformed to provide rounded recesses. The anchor strap can be made more rigid by forming a corrugation-like recess extending in the elongated direction of the strap. When a force is applied to the anchor strap causing it to move angularly away from the base member, the support webs cause the adjacent surfaces of the base member to act as deformation zones relieving the force on the connection between the base member and the structural steel member.

Abstract: A method of reinforcing rock strata, such as that around underground openings in mines, is effected by using a first wooden reinforcing dowel to drive a second wooden reinforcing dowel into contact with resin capsules located at the inner end of a borehole. The first dowel is then removed from the borehole while additional resin capsules are positioned in the borehole and a further wooden dowel is then inserted into the borehole so as to become embedded in mixed resinous composition from the additional capsules. In this manner it is possible to reinforce the strata to a considerable depth, for example upwards of 16 feet, without the danger of metallic drill rods becoming jammed in the borehole and thereby obstructing subsequent cutting of the reinforced strata by mining machinery.
