Abstract:
The present invention utilises impact-driven fastener (1) having a twisted body having: a common axial core (2) a protruding helix (3) and a trailing elongate lost-end driving shank: (4) of reduced radial diameter. The fastener incorporates two or three loosely wound loosely wound thread-cutting blade-like helical projections (5) extending radially from a solid axial core (2). These blade-like projections (5) are inclined upon a sweeping helical angle (8) of less than 42° to the longitudinal axis (9) of the core (2). The elongate shank (4), which carries no swept angle thread-cutting blades, has a reduced cross sectional diameter that is approximately one half or less of a cross-sectional circumscribed diameter (7) of a protruding helix (3), from which it extends coaxially, such as to fit into and cooperate with a driving adapter (21) having a hollow leading end (24), said leading end of a driving adapter having an external diameter that is less than a cross-sectional circumscribed diameter (7) of the fastener (1).
Abstract:
A composite wall tie structure (1) is disclosed for supporting or anchoring building materials to a building structure. The composite wall tie has a vertical leg (20) for affixation to a building structure and a horizontal leg (10) for placement in the mortar between courses of building materials. The horizontal portion (10) of the wall tie (1) has bristle-like protuberances (60) and/or perforations (50) thereon for anchoring the leg (10) within mortar. The materials of construction of the wall tie (1) are preferably selected from composites that are moisture impermeable and corrosion resistant. The wall tie (1) system may also comprise a mounting and alignment bracket attached to the vertical legs (20) of multiple wall ties (1) at regular horizontal intervals to accommodate the secure attachment of wall ties (1) to wall studs.
Abstract:
The present invention concerns a device for securing an insulation board within a cavity wall, comprising an inner wall (1), an outer wall (2) and a cavity (3) in between said inner and outer walls in which insulation boards (4) are accommodated, said device comprising: wall anchor means (5) for securing the inner wall to the outer wall; retaining means (6,7,9) for fixating an insulation board in the cavity; said retaining means including projections (7) gripping an end portion of the insulation board; wherein the retaining means include a mounting element (6) adapted to be fastened to the inner wall; the anchor means comprises an elongated (5) member with holding means, which cooperate with corresponding receiving means (12,14,15,16) on the mounting element for securing the anchor member to the mounting element; and the projections are formed in the mounting element. Hereby, a better insulation quality may be achieved as the insulation boards may be positioned against a smooth inner wall without any wall ties pre-mounted, on which the insulation panels otherwise could be damaged. The insulation mounting procedures becomes much simpler and easier by a device according to the present invention, saving a considerable amount of time and consequently labour costs.
Abstract:
A support member system includes a set of elongate members (2). Each elongate member (2) has a first end (53) and a second end and a predetermined length. The predetermined length of each elongate member (2) is different from the predetermined length of each of the other elongate members (2). An end member (10) has an elongate member engagement portion (12, 13) adapted to engage with the first end (53) of an elongate member (2), and a support structure engagement portion (15). The support structure engagement portion (15) is adapted to engage with a support structure (8). The elongate member engagement portion (12, 13) permits the distance from the wall engagement portion (15) to the second end of the elongate member (2) to be adjustable at least up to the length of the next longer elongate member (2) in the set.
Abstract:
A corrugated board ((32) is secured to the inner wall (12) of a cavity wall construction (10) to establish a defined spacing (25) between the inner and outer walls (12, 13) and prevent excess mortar from bridging (28) to the inner wall (12). The corrugated board (32) has a series of spaced channels, furrows or grooves (34) into which an anchor (24) projects into the studs (16) of the inner wall (12) to secure the outer wall (13). The corrugated board (32) is installed prior to the construction of the outer wall (13) and establishes a minimum spacing or gap (25) between the walls (12, 13) based upon the thickness of the board (32). The outer wall (13) is constructed immediately adjacent to the outer face of the corrugated board (32). The grooves or channels (34) of the corrugated board (32) create a chamber for vapor and air circulation. The board (32) eliminates bridging by the mortar (22) and provides an air conduit to exhaust even the minimal amounts of vapor that will occur in the cavity (25).

The frame can comprise steel beams (30) , or also comprise a truss having an open web, and a slide rail (40) attached to the truss chords in a generally plumb orientation. Embodiments of the hook member substantially encircle one or more slide rails and thereby retain the rails. Other embodiments fit within a channel attached to solid steel webs, or concrete frames. The device's other end is positioned over a course of masonry units (12), and when embedded in mortar (20), the cells of the masonry units do not require grouting. Other connecting device embodiments comprise an anchor member securely joined to the member, the connecting device providing multiple points of attachment with the masonry, or multiple members joined to the anchor member.

Abstract:
A device fixable to blockwork has the form of a tie (10) with first and second elongate body parts joined one to the other at their first ends whilst their second ends are apertured to receive fixing means for fixing the tie to blockwork. The body parts may be coplanar or be disposed at right angles one to the other. The tie as described (Fig. 1) is of moulded plastics material and the body parts are joined by a live hinge. Edges of each body part carry walls (16, 17) extending normally of the plane of the tie and these walls are of increasing height in moving from the hinge (20) to the ends (12, 14) of the tie. Fixture of the tie to blockwork is achieved by driving the body of fixing means (30, Fig. 2; 54, Fig. 3; 74, Fig. 4; 94, Fig. 5) into blockwork through the apertures (22, 24) such that the bevelled undersurfaces of heads of the fixing means bear on bevelled edges (26) of the apertures. Various fixing means are described all of which are of moulded glass fibre reinforced plastics material, are rectangular in section along their length and taper inwardly in moving from their trailing to their leading ends. One described fixing means (30, Fig. 2) is slotted to form a pair of legs (18) when driven into blockwork, whilst others (Figs. 4, 5) are formed with lands running along at least part of their lengths. A method of bonding blockwork, joining adjacent blocks of material, to form a wall is described.
