摘要:
Two-piece fastener assembly for securing thermoplastic roof membranes to an underlying roof deck having: a batten bar coated with a thermoplastic coating on its top surface; a plurality of openings in the batten bar; and fasteners positioned in the plurality of openings for securing the batten bar and one thermoplastic roof membrane to the underlying roof deck. In a method aspect the steps of securing thermoplastic roof membranes to an underlying roof deck includes: placing a first thermoplastic roof membrane on the roof deck; placing a batten bar on the marginal portion of the first thermoplastic roof membrane and securing the batten bar along with the first thermoplastic roof membrane to the roof deck by use of the fasteners; placing a second thermoplastic roof membrane to overlap the batten bar and the marginal portion of the first thermoplastic roof membrane; and applying heat and pressure to the batten bar and the overlapped portion of the first and second thermoplastic roof membranes to fuse them together and provide a waterproof covering over the roof deck.

The assembly includes fasteners hold in a carrier (170). The carrier includes a plurality of adjacent sleeves (72), each of which includes an upper breakable portion (74), a middle wall portion, and a lower breakable portion. When a fastener is driven into a work piece, the upper and middle portions of the fastener sleeve break away and the lower portion breaks into fragments. The carrier (170) is made from a mixture of a stiff polyolefin material and a particular filler. The plurality of carrier sleeves (72) include two end sleeves. At least one end sleeve includes a lateral end extension (171 ; 173) in the lower breakable portion which helps to balance and stabilize the fastener assembly in a fastener driving tool.

An obliquely collated strip of brads (100) useable in an angled magazine (50) of a fastener driving tool (10), each brad (30) having a head (70) on one end and a point (80) on an opposing end. The point (80) of each brad (30) of the collated strip (100) has a tip (90) defined by converging facets (91,92,93,94) to form an edge (96) or surface (91) at an acute angle relative to an axis of the brad (30). The edge (96) or surface (91) of each brad forms a substantially continuous edge (110) of the collated strip (100). The head (70) of each brad (30) of the collated strip (100) is arranged step-wise relative to the head of an adjacent brad (30). The step-wise arrangement of heads (70) form a stepped edge (120) substantially parallel to the substantially continuous edge (110) of the collated strip (100). The head of each brad (30) slopes at an angle relative to the axis of the brad (30), with the angle of the head (70) sloping oppositely relative to the angle of the substantially continuous edge (110) of the collated strip (100).
摘要:
The invention pertains to a U-shaped clip-on slide nut (10) with two parallel sliding limbs (11, 12) provided with notch elements and capable of being clipped onto an undercut ridge (19). One sliding limb (11) is provided with a bore (13) and the other limb (12) is provided with a threaded bore (14) aligned with the bore (13) and accommodating a clamping screw (20). The invention facilitates fixing of a component (30) on the ridge (19) in that the bore is a blind bore, the clamping screw is a countersunk screw (20), and at least one sliding limb (11, 12) is provided in addition with a screw recipient (15) for a securing screw (31).
