Use of a synthetic resin system as an adhesive for chemical fixing technology, especially for fixing anchoring means in drilled holes, which synthetic resin system includes a) a reaction resin based on , -unsaturated compounds, b) a reaction resin based on compounds that include CH-acidic methylene groups, and c) a catalyst, and to related subject matter.

Systems and methods provide for the installation of fasteners in a composite panel with a fastener insert. A fastener insert for a composite panel includes a body and a at least three arms extending from the body. The body has a top face and a central hub extending rearward from the top face. The top face has an outer dimension between opposing edges. The arms extend from the central hub on a rear side of the body. In a retracted configuration, the arms are folded inward toward the central hub so that the arms do not extend beyond the outer dimension of the top face. In an extended configuration, the arms extend outward from the central hub beyond the outer dimension of the top face.

An adhesive joint of a first hollow profile to a second hollow profile, and a method of producing such an adhesive joint. The second hollow profile is surrounded in an overlapping region by the first hollow profile, and a core connected to the first hollow profile is arranged in the overlapping region inside the first hollow profile and the second hollow profile. An expandable structural adhesive is arranged between the core and the inner face of the second hollow profile.

A structural arrangement for securing scaffolding to a building wall. The structural arrangement includes the building wall with a recess, a faade anchor secured to the building wall and having a receptacle for accommodating at least one securing element. The securing element engages in the receptacle in the faade anchor on the one hand and in the recess in the wall on the other hand. The faade anchor provides a supporting face facing the building wall. A compensating material is provided between the supporting face and the building wall in such a manner that the faade anchor makes contact over its supporting face with, and is supported by the building wall indirectly via, the compensating material.

An anchoring method of anchoring an anchoring element in a construction object is provided, where a surface of which object has at least one of pores in a surface, structures in a surface (such as an arrangement of ridges with undercut), a inhomogeneous characteristic with makes the penetration of a surface by a liquid under pressure possible, thereby creating pores filed by the liquid underneath the surface, and of a cavity. The method includes the steps of: providing a first element and a second element, the first element comprising a thermoplastic material; positioning the first element in a vicinity of said surface and/or of said cavity, respectively, and positioning the second element in contact with the first element; and causing a third element to vibrate while loading the first element with a force, thereby applying mechanical vibrations to the first element, and simultaneously loading the first element with a counter-force by the second element.

Plugs with a high dimensional tolerance of about +/33 percent for successfully plugging holes even if the holes were miss-drilled to have diameters that vary up to thirty-three percent smaller or larger from the specified hole/plug size of any chosen material, tapered to approximately one degree or un-tapered, having a three-dimensionally textured surface made up of elements imparted upon a surface of the plug causing the plug to exert a strong hold-in force of outwardly directed pressure against a side wall of a drilled hole into which the plug is installed keeping the plug within the drilled hole so that the plug does not protrude out of the hole preventing tripping hazards when the hole is drilled in walking surfaces all without requiring the addition of a glue, special tools, or special fasteners. The plug has a 30 second or less installation time.

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.

An anchoring adhesive includes effective amounts of an isocyanurate compound and a vinyl ester compound that react and cure to form a composition having high compressive strength, high tensile strength and low shrinkage. The anchoring adhesive can be used to firmly bond anchor pins to boreholes in concrete, steel, wood, and other substrates.

Anchor fastening element for fastening an object to a wall having a drilled hole, which comprises a threaded bolt having a threaded portion at one end and an anchor portion at the other end and also having a shank portion in between. The threaded portion and the anchor portion have a low ductility and the shank portion has a higher ductility.

A method for installing fastener in a base material. The fastener has a shank having a first end and a second end defining a length, a head provided at the second end, and a thread provided on the shank which includes a leading edge and a trailing edge adapted remove portions of the base material when inserted into the base material. The method includes forming a hole having a diameter which is a nominal shank diameter of the fastener to be installed in the base material. The hole is then filled with an adhesive having a viscosity of 350 cP or less. Finally, the fastener is rotated into the hole such that the adhesive is forced into portions of the base material adjacent to the shank and thread when the thread is fully inserted into the hole.
