[0001] The invention relates to a guide rail section for partitioning part of a roadway,
provided with a foot and side walls adjoining the foot, wherein at one extremity of
the guide rail section the foot and/or the side walls can be coupled to the respective
foot or side walls of a similar guide rail section and wherein at least one wall of
the guide rail is provided with a hole and a detachable assembly hatch fitting in
it near the extremity.
[0002] Such a guide rail section is known from practice and is used for composing a guide
rail of it by coupling several guide rail sections together. Guide rail sections are
manufactured in a factory and then transported to the desired place of erection. In
this place the guide rail sections must be easy to couple in order to make the roadway
on the spot available for traffic again as soon as possible. The intercoupling of
guide rail sections takes place with strips of sheet metal which are laid longitudinally
over the extremities of two guide rail sections adjoining each other and are fastened
to the guide rail sections with bolts and nuts and/or rivets. In order to be able
to reach the bolt or nut in the interior of a guide rail section, an assembly hatch
is fitted near the extremity of a guide rail section. The known assembly hatch has
a rectangular shape and is fastened to the guide rail section by means of a number
of bolts. On a guide rail strength requirements are imposed both as to longitudinal
and transverse load. The assembly hatch must not reduce the strength properties of
the guide rail to beneath the minimum strength requirements.
[0003] A drawback of the known assembly hatch is that fitting of it after guide rail sections
have been coupled together requires much time. It is strived for to have a day or
night shift install at least thousand metres of guide rail sections. The necessity
of fitting the assembly hatch constitutes a limitation of the amount of guide rail
that can be installed per shift.
[0004] Another drawback is that, in case of a temporary installation, after some time the
assembly hatch is hard to remove due to which the removal of a temporary guide rail
requires much time.
[0005] An object of the invention is to provide a guide rail section with which the above-mentioned
problems are eliminated or reduced to a considerable extent and with which other added
advantages are achieved.
[0006] To this end a guide rail section in accordance with the invention is characterized
in that the assembly hatch is provided with at least a twist-lock fastening for the
clamping of it in the wall. The twist-lock fastening enables quick fitting of the
assembly hatch; the design of the construction can be so sturdy that the twist-lock
fastening is still detachable without a problem after long exposure to the outside
climate.
[0007] A further embodiment of the invention suitable for application with a great variety
of shapes of the assembly hatch is characterized in that the twist-lock fastening
comprises an arm fastened on the hatch which arm is suitable for being brought into
locking contact with the inward part of the wall.
[0008] An embodiment of the invention in which the assembly hatch can be fitted very quickly,
is characterized in that the assembly hatch is an essentially circular plate and that
the inward part of the wall is provided with a clamping plate on which the arm can
be brought into locking contact. This embodiment has the added advantage that less
concentration of stress occurs around the hole in which the assembly hatch fits due
to which the mechanical strength of the guide rail section is influenced less disadvantageously.
[0009] After being shaped the guide rail sections are galvanized to make them resistant
to the corroding effect of the climate. To prevent residual acid from the galvanizing
baths from being left in slits, a further embodiment of the invention is characterized
in that the clamping plate is fastened at a distance from the wall.
[0010] To further simplify the fastening of the assembly hatch a further embodiment of the
invention is characterized in that the assembly hatch is provided with means for turning
the assembly hatch around its centre.
[0011] The invention will be illustrated in the following with reference to a drawing.
[0012] In the drawing
Fig. 1A is a longitudinal view of a guide rail section,
Fig. 1B is a front view of a guide rail section and
Fig. 2 is a further detail of an assembly hatch in accordance with the invention.
[0013] In Fig. 1A reference number (1) represents a guide rail section. Guide rail section
(1) has a foot (2) and side walls (3). At one extremity side wall (3) is provided
with a round hole (4) in which an assembly hatch (5) is fitted. At the extremity near
assembly hatch (5) a composite flange (6) is fastened by means of a number of rivets
(7). If desired, the other extremity of the guide rail section can be provided with
a second hole (8) and an assembly hatch (9) fitting in it.
[0014] Fig. 1B shows a front view of a guide rail section. At one extremity the guide rail
section is provided with a composite flange (6) which runs across practically the
entire inner wall of the guide rail section. This flange (6) is to be connected to
the extremity of a similar guide rail section by means of bolts.
[0015] Fig. 2 shows part of a guide rail section with the hole (4) and the assembly hatch
(5) fitted in it. The round assembly hatch (5) is provided with arms (11) which are
fastened rigidly to the assembly hatch (5). On the inner wall of the guide rail section
clamping plates (12) are fitted at a distance from the wall. In the drawn situation
the parts (13) of the arms (11) lie under the clamping plates (12), viewed in the
drawn situation, and are in locking contact with the clamping plates (12). The strip
(14) is a stop for limiting the angle of rotation of the assembly hatch. Reference
number (15) indicates a central hole in the assembly hatch in which an appropriate
tool fits to enable rotation and with that fastening or detachment of the assembly
hatch.

is provided with a hole (4,8) and a detachable assembly hatch (5,9) fitting in it
near the extremity, characterized in that the assembly hatch is provided with at least
a twist-lock fastening for the clamping of it in the wall.
