摘要:
A stackable moulded junction box section, suitable for construction of underground junction boxes. The section includes integrally moulded support means (55,56,57). The support means can comprise a step (52) and can also comprise a receiving means (56,57) for receiving and supporting a support (58), which may be moulded integrally with the section and then separated for use. The section may comprise inner (50) and outer (51) walls joined by cross-reinforcement portions (52) which divide the space between the walls into cavities (53). Provision to form apertures between the cavities, which may comprise a knock out portion (54), can be provided. The apertures may be open to the bottom of the section, so that the section may be placed over a conduit. The section may include projections to enable it to be stacked on end. In another embodiment the section is formed from two or more separate interlocking components.
摘要:
A hurdle type barrier system where there is provided an assembly comprised of at least two substantially horizontally arranged barrier boards (1), together with at least two substantially vertically arranged support posts (2), said support posts having provided upon them an upper and lower receiving means (3,4) for accepting the needs of the two barrier boards; individual receiving means each being arranged whereby it extends to both the inboard (4) and outboard (3) opposing sides of the post in line with and relative to the barrier board, where the receiving means on at least the inboard part (4) is open to receive the barrier board, and where the fit of the barrier board within the receiving means is such that there is interference between the inner surface of the receiving means and the outer surface of the barrier board and where provision is made to prevent unintentional disassembly of the barrier.
摘要:
A method for securing a close fitting preformed sleeve 12 onto a support surface 10. The sleeve 12 is coated internally with adhesive and the adhesive is covered by a liquid layer, such as isopropanol to prevent the adhesive contacting the body 10 while the sleeve is being fitted thereon. The sleeve dimensions are no larger than the body and preferably smaller so as to provide the close fit.
摘要:
A retro-reflective assembly comprising a substrate (10, 30) and a binder layer (12, 32) coated onto the substrate. Glass beads (14, 34) which are partially metallised (16, 36) are at least partially embedded in the binder layer. The assembly can be joined to another structure, e.g. a cover (38) or a support (20) by high frequency welding at a location where partially metallised beads are present.
摘要:
A marker post which can be quickly installed at the edge of a road comprising a flexible body (10) of part circular cross-section with an elongated metal base (12) preferably of T-shaped cross-section. To secure the post in place the body is flexed away from the base so that the base can be driven into the ground with a hammer. When the body is released it returns to an upright disposition.
