Abstract

A connection system (1) for releasably connecting a first member (2) to a second member (3), as the first member (1) comprises an elongate body member (4) to one end of which is attached a mounting plate (5), located orthogonally with respect to the longitudinal axis (6) of the body member. The mounting plate (5) is provided firstly with a through hole having an axis parallel to the longitudinal axis, and secondly with a stud (9) projecting from the opposite side of the mounting plate (5) to the body member (4). The second member (3) is provided firstly with a threaded stud (22) for passage through the hole (7) of the mounting plate, and secondly with a through hole (21) through which the stud (9) of the mounting plate (5) may be passed, whereby when the first and second members (2, 3) are assembled together, the operative need only apply one nut (30), and possibly a washer, to the threaded stud (22) to fasten the first and second members together.

Description

I
Title of the Invention
Connection system.
Field of the Invention
This invention relates to a connection system for releasably connecting a first member to a second member.
Background of the Invention
A frequently used item on multi-storey building sites, is a barrier, made up of a plurality of individual panels located end-to-end, and possibly slightly overlapping by hooking onto a plurality of spaced upright posts, with inwardly facing hooks on the posts.
Lower ends of the post constitute spigots for insertion into sockets provided by a boot in turn slotted onto a stub shaft.
Conventionally, the stub shafts are attached e.g. to structural steelwork, such as an UB, by drilling a pair of spaced-apart holes through the web of the UB, for alignment with a pair of holes in a mounting plate of the stub shaft.
To attach a stub shaft to an UB, the operative must align the holes, insert two bolts, apply two nuts, usually with washers, and tighten the nuts, frequently at a location overhanging a floor of a multi-storey building under construction.
It follows that to remove a stub shaft, the reverse of the above procedure must be followed.
* Object of the Invention A basic object of the present invention is the provision of an improved connection system.
Summary of the Invention
According to the invention, there is provided a connection system for releasably connecting a first member to a second member, wherein (i) the first member comprises an elongate body member to one end of which is attached a mounting plate, located orthogonally with respect to the longitudinal axis of the body member; (ii) the mounting plate is provided firstly with a through hole having an axis parallel to the longitudinal axis, and secondly with a stud projecting from the opposite side of the mounting plate to the body member; and (iii) the second member is provided firstly with a threaded stud for passage through the hole of the mounting plate, and secondly with a through hole through which the stud of the mounting plate may be passed, whereby when the first and second members are assembled together, the operative need only apply one nut, and possibly a washer, to the threaded stud of the second member to fasten the first and second members together.
Advantages of the Invention By providing a connection system having only one nut, both the connection and disconnection times for the system in accordance with the invention are reduced by half, whilst only half the number of nuts need to be carried by the operative.
Preferred or optional features of the Invention The first member is a stub shaft.
The stud of the mounting plate is plain.
The stud of the mounting plate is secured to the mounting plate by welding.
The stud of the mounting plate is provided by the stem of a bolt.
The bolt is a conventional hexagonal headed bolt.
A lock nut is applied to the threaded stem of the bolt on the other side of the mounting plate to the hexagonal head.
The second member is a universal beam (UB).
The stud of the UB is plain.
The stud of the UB is secured to the web of the UB by welding.
The stud of the UB is provided by the stem of a bolt.
The bolt is a conventional hexagonal headed bolt A lock nut is applied to the threaded stem of the bolt on the other side of the web to the hexagonal head.
The lock nuts of the threaded stems of the bolts of the first and second members serve additionally as spacers between the mounting plate and the web of the UB.
Brief Description of the Drawings
Figure 1 is a side elevation of a first member, in the form of a stub shaft.
Figure 2 is a side elevation of a second member, in the form of an UB; and Figure 3 shows the first and second members of Figures 1 and 2 connected by the connection system of the invention.
Detailed description of the drawings
A connection system I is for the releasable connection of a first member 2 to a second member 3.
The first member 2 comprises an elongate body member 4 constituting a stub shaft to one end of which is welded a mounting plate 5 which is located orthogonally with respect to longitudinal axis 6 of the elongate body member/stub shaft 4.
The mounting plate 5 is provided with a first through hole 7 and spaced therefrom with a second through hole 8 to receive a stud 9 constituted by a stem 10 of a bolt 11, the stud 8 projecting to the opposite side of the mounting plate 5 to that of the elongate body member/stub shaft 4 along an axis 12 parallel to that of the longitudinal axis 6. A hexagon bolt head 13 engages one face 14 of the mounting plate 5, whilst a lock nut 15 is threaded on the stem 9 and tightened against the opposite face 16 of the mounting plate 5.
The second member 3 is an 1" - section universal beam (UB) 17 having an upper flange 18 jointed to a lower flange (not shown) by a web I 9, which is provided with through holes 20 and 21 at the same spacing as the holes 7 and 8 of the mounting plate 5. The hole 20 receives a stud 22 constituted by a stem 23 of a bolt 24, the stem 23/bolt 24 having an axis 25 extending orthogonally with respect to the plane of the web 19 and, in use, parallel to the longitudinal axis 6. A hexagonal bolt head 26 engages one face 27 of the web 18, whilst a lock nut 28 is threaded on the stem 23 and tightened against the opposite face 29 of the web 18.
To attain the assembled mode of the connection system I illustrated in Figure 3 from the disassembled mode illustrated in Figures 1 and 2, the operative grips the first member 2 and passes the stud 9 through the hole 21, and the stud 22 through the hole 7 until a portion of the face 16 of the mounting plate 5 abuts lock nut 28 and, more or less simultaneously, lock nut abuts face 29 of the web 19. After this initial engagement of the first and second members 2, 3, the operative only needs to apply, and tighten, lock nut on the stem 23.
It follows that disassembly requires the reverse of this procedure, and compared with prior art proposals the operator need only apply, remove, and carry one lock nut 30.
