A connector is disclosed for use in forming a joint between a first surface and a second surface. The connector comprises a housing. The connector also comprises a tendon. A portion of the tendon can protrude from the housing through a seal. The seal is configured to sealably cover an open end of the housing such that the tendon can move through the seal and laterally sideways across the open end together with at least a portion of the seal. Also disclosed is a connector system for use in forming a joint, and a method of installing a connector to form a joint, between a first surface and a second surface. The connector system and method comprises and makes use of the housing and the tendon.

A device (1) for introducing a plugging compound (20) into a borehole (21), the device having a sleeve (2) with a cavity (3) for receiving the plugging compound (20). On one side, the sleeve (2) has a discharge opening (5), corresponding to the cavity (3), for discharging the plugging compound (20), and a support section (7), projecting laterally from the sleeve, for providing a support option for the sleeve (2) during introduction of the plugging compound (20). On the opposite side of the sleeve (2), an upper opening (4) is provided, through which a piston (16) together with a feed plate (18) protrudes into the cavity (3). The piston (16) is movable relative to the sleeve (2) in such a way that the feed plate (18) can be displaced in the cavity (3), for example to allow the plugging compound (20) to be received and dispensed.

A post-installed anchor by which high drawing strength can be reliably maintained and an anchoring operation can be stably performed, or the like. A post-installed anchor, which is anchored into an anchor hole having a diameter expansion portion, includes: an anchor main-body inserted in the anchor hole; a plurality of straight-shaped guide opening portions formed to penetrate in a radial direction at positions corresponding to the diameter expansion portion; a plurality of spread pieces slidably provided at the respective guide opening portions and engaged to the diameter expansion portion in an anchoring state in which the plurality of spread pieces spread in the radial direction; and a cone portion that slides the respective spread pieces to an outside in the radial direction to spread the plurality of spread pieces.
摘要:
Universal device, method and tool for allowing installation of bolts in substrates such as building block, concrete and gypsum walls without having to adapt a drill to an anchor and an anchor to a bolt. Bolts of large variety of sizes may be installed using the method, tool and materials of the invention using a single diameter drill, while allowing accurate positioning of the bolt in the substrate even when the installation hole is drilled off the accurate location.
摘要:
A structural arrangement for securing scaffolding to a building wall. The structural arrangement includes the building wall with a recess, a façade 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 façade anchor on the one hand and in the recess in the wall on the other hand. The façade 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 façade anchor makes contact over its supporting face with, and is supported by the building wall indirectly via, the compensating material.

Various embodiments include an infusion bolt and methods of manufacturing such a bolt. In one embodiment an infusion bolt includes: a head having an axially accessible opening extending therethrough; and a shaft extending from the head, the shaft having: an inner cavity fluidly connected with the axially accessible opening of the head; a radially outer surface surrounding the inner cavity; and a set of axially extending apertures along the radially outer surface, the set of axially extending apertures fluidly connected with the inner cavity and the axially accessible opening in the head.
摘要:
An anchor rod is disclosed. The anchor rod includes an attachment region and an anchoring region which is insertable into a borehole and which has a profiled section. The profiled section interacts with a curable organic and/or inorganic mortar compound filled into the borehole. The profiled section includes a plurality of expansion sections disposed axially in a row which are conically shaped. For each of the plurality of expansion sections, a diameter of the expansion section increases in a direction toward a free front end of the anchor rod, a ratio of a distance of the expansion section to a mean borehole diameter is 0.40 to 0.60, a ratio of an outer diameter to a core diameter of the expansion section is 1.35 to 1.55, and a cone angle of the expansion section is 22.5° to 27.5°.
