Description

SECONDARY WALL METHOD AND SYSTEM
The invention relates to a method for provision of a secondary internal wall for a structure such as a tunnel or the like, and in particular to a method for assembly of a secondary tunnel wall, to a modular internal wall system and for example modular tunnel wall system, and to a structure such as a tunnel which has been provided with a secondary internal wall in accordance with such a method or by development of such a system. The invention relates to a method and system for providing a secondary wall via a method of modular assembly in situ, and to a system adapted for the same.
Introduction
A need may arise in tunnels and like structures defining an internal cavity to provide a secondary wall or lining on the internal face of the structure to give additional functionality.
Road and railway tunnels in particular might have a particular set of desired internal wall properties. Control of appearance may be desirable for simple aesthetic purposes and/ or to give particular desired surface appearances for other reasons, for example areas of controlled low or high reflectance. Other funcfionalifies such as passive fire-resistance may be useful. It is frequently more practical or cost-effective to provide these inner wall properties by means of a secondary wall structure internal of the tunnel face Of applicable including the inner face of any direct primary lining structure).
A secondary wall structure may also provide a useful way to define a desired wall profile more accurately and for example a desired reduced and/ or more accurately controlled functional bore profile within a larger primary tunnel structure, for example to produce a controlled piston effect within the functional bore as a vehicle passes through.
Similar considerations arise in respect of other structures such as railway arches and the like.
Methods of providing a secondary wall structure are known in which modular wall panels are fabricated off-site to be assembled in situ. For example, methods of providing a secondary wall structure are known in which modular wall panels are assembled in situ mounted on to rails fixed to the tunnel face for example towards the top and bottom of the panel. The panels need to be presented to the tunnel face in suitable alignment to the tunnel face and to each other, and if applicable to such mounting rails, and fixed to the tunnel face in that suitably aligned arrangement. The process of accurately aligned assembly may be technical difficult and time consuming.
There is a general desire to provide a method for the modular assembly of a secondary internal wall for a structure such as a tunnel, and a modular internal wall system and for example modular tunnel wall system for use in such a method, in which the assembly process is simplified and/ or facilitated and/ or able to be performed more rapidly.
Summary of Invention
In accordance with the invention in a first aspect, a method for the provision of a secondary wall on the face of a structure such as a tunnel comprises the steps of: attaching a locating rail to the face; providing a wall panel having at least one locating and positioning formation; presenting the wall panel to the face; associating the at least one locating formation with the locating rail in such manner as to effect a locating engagement between the wall panel and the locating rail; positioning the wall panel; attaching the locating formation to the locating rail in such manner as to effect a mechanical engagement therebetween.
More preferably, the method comprises attaching to the face a locating rail and a fixing rail spaced apart in parallel; providing a wall panel having spaced apart thereon at least one locating and positioning formation and at least one fixing formation; presenting the wall panel to the face; associating the at least one locating formation with the locating rail in such manner as to effect a locating engagement between the wall panel and the locating rail; positioning the wall panel so as to bring the at least one fixing formation into proximity with the fixing rail; attaching the fixing formation to the fixing rail in such manner as to effect a mechanical engagement therebetween; attaching the locating formation to the locating rail in such manner as to effect a mechanical engagement therebetween.
In particular preferably, the step of attaching the fixing formation to the fixing rail comprises locking the fixing formation to the fixing rail in such manner as to effect a fixed mechanical engagement therebetween. Additionally or alternatively preferably the method comprises a further step, which may for example be performed immediately prior to or immediately subsequently to the forgoing step, of locking the locating formation to the locating rail in such manner as to effect a fixed mechanical engagement therebetween.
More completely, the method comprises providing a plurality of wall panels and presenting each wall panel successively to the face and fixing each wall panel successively thereto in the manner above described.
The method is thus a method for the modular construction of a secondary wall structure internal of the primary face of the structure (which term if applicable may include the inner face of any direct primary lining of the internal surface of the structure). Modular panels are successively offered up to and fixed onto the rails mounted onto the face.
Methods of providing a secondary wall structure are known in which modular wall panels are assembled in situ mounted on to rails fixed to the face of the tunnel or other structure for example towards the top and bottom of the panel.
The method of the invention is distinctly characterised in that panels are provided with suitable attachment formations before being presented for assembly at the face of the tunnel or other structure, and for example provided with suitable attachment formations by being fabricated integrally with suitable attachment formations as an off-site pre-fabricated construction, and further in the preferred case in that each panel has two distinct types of attachment formation, being at least one locating formation and at least one fixing formation. The method comprises presenting the panel on which the attachment formations have already been provided to the internal face of the structure on which a locating rail and preferably at least a pair of rails comprising a locating rail and a fixing rail spaced apart in parallel have already been attached. Each locating formation is configured when the panel is so presented to cause the formation to locatingly engage upon the locating rail.
In the preferred case, at least a pair of rails comprising a locating rail and a fixing rail spaced apart in parallel is provided. The relative juxtaposition of the locating and fixing formations, and of the locating and fixing rails, are such that with the locating formation locatingly engaged upon the locating rail, the fixing formation may be brought into immediate proximity of the fixing rail, and a fixed mechanical engagement onto the fixing rail may thereby be effected. Preferably both the locating formation and the fixing formation are then locked into position on their respective rails. The system is adapted to the presentation and hanging of successive panels onto the face of the structure such as the face of the tunnel or other structure in a very quick and efficient manner.
Preferably the locating formation is configured to have two functional configurations: a locating configuration in which it is adapted to facilitate relative movement of the wall panel and the face to position the same and in the case where a further fixing rail is provided to allow the fixing formation to be brought into immediate proximity of the fixing rail; and a locking configuration in which it is adapted to effect a fixed engagement between the wall panel and the locating rail. For example, the locating formation in the locating configuration may be adapted to effect a sliding engagement or a hinged engagement or a pivoting engagement or combinations thereof between the wall panel and the locating rail.
Thus, the wall panel on which the attachment formations have already been provided may be presented to the internal face of the structure such that each locating formation is caused to locatingly engage upon the locating rail. At this point the locating formation is in the locating configuration allowing the panel to be suitably positioned, for example by sliding along and/ or rotating about the locating rail, to bring the fixing formation into immediate proximity of the fixing rail, and a fixed mechanical engagement onto the fixing rail effected. The locating formation is then placed in the locking configuration in which it is also locked into position. Thus successive pre-fabricated panels may be presented for hanging onto the face of the structure such as the tunnel face and successively engaged onto and locked into position thereon in a quick and efficient manner.
In a first principal example embodiment at least two rails are provided, disposed generally horizontally in parallel on the face, so as to comprise an uppermost rail and a lowermost rail. In the preferred case the locating rail is either the uppermost or lowermost rail and the fixing rail is correspondingly either the lowermost or uppermost rail.
The method comprises associating the at least one locating formation with the locating rail effect a locating engagement, positioning the wall panel so as to bring the at least one fixing formation into proximity with the fixing rail, and attaching the fixing formation to the fixing rail.
More completely, the method of the first principal example comprises the steps of: attaching to the face of the tunnel or other structure at least two rails, disposed generally horizontally in parallel on the face, so as to comprise an uppermost rail and a lowermost rail, wherein the locating rail is either the uppermost or lowermost rail and the fixing rail is correspondingly either the lowermost or uppermost rail; providing a wall panel; providing at least one locating formation; presenting the wall panel to the face; associating the at least one locating formation with the wall panel and the locating rail in such manner as to effect a locating engagement between the wall panel and the intermediate locating rail; positioning the wall panel; providing at least one fixing formation; associating the at least one fixing formation with the wall panel and the fixing rail in such manner as to effect a fixed mechanical engagement therebetween.
The first principal example is particularly characterised therefore by the provision of a first aligning and locating rail onto which each panel is first mounted so as to be moved into correct alignment before a final engagement to the other rails is effected. This allows each panel to be presented directly to the first rail at an angle to the wall and moved into a generally parallel alignment to the wall (for example, allows a vertical wall panel to be presented vertically) and facilitates rapid assembly of successive panels in situ.
Preferably, the locating formation is configured to have two functional configurations, a locating configuration in which it is adapted to facilitate relative movement of the wall panel and the face such as to allow the fixing formation to be brought into immediate proximity of the fixing rail and a locking configuration in which it is adapted to effect a fixed engagement between the wall panel and the locating rail.
Convenently for example, the locating formation may be adapted to effect a hinged engagement or a pivoting engagement or combinations thereof between the wall panel and the locating rail.
Thus, the method comprises associating at least hinged or pivotable locating formation with the locating rail effect a locating engagement, in which engagement the hinged or pivotable locating formation is able to hinge or pivot and thus enable the panel to rotate about a hinge or pivot axis of the formation; rotating the wall panel about the hinge or pivot axis so as to bring the at least one fixing formation into proximity with the fixing rail, attaching the fixing formation to the fixing rail, and locking the locating formation so that is it not able to hinge or pivot.
Where optional intermediate rails are provided, at least one optional intermediate fixing formation may be provided associated with each such rail such that the relative juxtaposition of the locating and fixing and intermediate fixing formations, and of the locating and intermediate fixing rails, are such that with the locating formation locatingly engaged upon the locating rail, the fixing formation may be brought into immediate proximity of the fixing rail, the intermediate fixing formation(s) may be brought into immediate proximity of the corresponding intermediate fixing rail(s) and a fixed mechanical engagement onto the fixing rail and intermediate fixing rail(s) may thereby be effected.
In a second principal example embodiment at least three rails are provided, disposed generally horizontally in parallel on the face, so as to comprise at least an upper fixing rail and a lower fixing rail and an intermediate locating rail between the upper fixing rail and the lower fixing rail.
The method comprises associating the at least one locating formation with the locating rail effect a locating engagement, positioning the wall panel so as to bring the fixing formations into proximity with the respective fixing rails, and attaching the fixing formations to the fixing rail.
More completely, the method of the second principal example comprises the steps of: attaching to the face of the tunnel or other structure an upper fixing rail, a lower fixing rail, and at least one intermediate locating rail between the upper fixing rail and the lower fixing rail, the rails being spaced apart in parallel; providing a wall panel; providing at least one locating formation; presenting the wall panel to the face; associating the at least one locating formation with the wall panel and the intermediate locating rail in such manner as to effect a locating engagement and for example a sliding engagement between the wall panel and the intermediate locating rail; positioning the wall panel; providing at least one upper fixing formation and at least one lower fixing formation; associating the at least one upper fixing formation with the wall panel and the upper fixing rail and the at least one lower fixing formation with the wall panel and the lower fixing rail in such manner as to effect a fixed mechanical engagement therebetween.
The second principal example is particularly characterised by the provision of an intermediate aligning and locating rail onto which each panel is first mounted so as to be held in correct alignment before a final engagement to the top and bottom rails is effected. This allows each panel to be presented directly to the mounting rails in a generally parallel alignment (for example, allows a vertical wall panel to be presented vertically) and facilitates rapid assembly of successive panels in situ.
Each panel is first positioned in the correct alignment by associating the at least one locating formation with the wall panel and the intermediate locating rail in such manner as to effect a locating engagement between them and for example by effecting a mounting engagement between them. That is, the locating formation is mounted so as to locate the panel onto the intermediate locating rail. Once the panel is correctly positioned, the upper and lower fixing formations are engaged respectively between the upper and lower fixing rails and the panel to lock it into the desired position. That is, the fixing formations are mounted so as to fixedly mount the panel, and for example respective upper and lower portions thereof at or in the vicinity of the upper and lower edges, onto the fixing rails and thereby fixedly engaged in position at the face.
The panel may be located correctly on the intermediate locating rail by sliding to an appropriate position before locking. Conveniently therefore the locating formation is configured to have two functional configurations, a locating configuration in which it is adapted to effect a sliding between the wall panel and the locating rail to facilitate relative movement of the wall panel and the face, and a locking configuration in which it is adapted to effect a fixed engagement between the wall panel and the locating rail.
Successive panels are successively located, positioned and locked in the same manner to build up a secondary wall structure in situ fixed on to the rails and thereby fixed to the face of the tunnel or other structure. Each panel may additionally be fixedly engaged in position to its immediate neighbour.
In all of the foregoing examples, the system of rails and locating and fixing formations enables rapid assembly in situ of panels that have been prefabricated for example off site.
The rails may be mounted directly or indirectly to the face of the tunnel or other structure. The rails are mounted to the face of the tunnel or other structure to present a series of outwardly facing mounting portions that together to define a mounting face for the secondary wall.
A wall panel may be planar or curved, with the rails thereby defining a complementarily planar or curved mounting face.
The rails are preferably mounted generally horizontally. In the case plural rails are provided the rails are preferably mounted generally parallel to each other.
The invention additionally comprises a secondary wall system provided on a face of a structure comprising a plurality of panels mounted thereon according to the foregoing method.
That is, the secondary wall system comprises: a locating rail attached to a face of a structure; a wall panel having at least one locating and positioning formation; wherein the at least one locating and positioning formation is associated with the locating rail in such manner as to effect a locating engagement between the wall panel and the locating rail; the wall panel is positioned; and the locating formation is mechanically engaged to the locating rail.
Preferably the secondary wall system comprises: a locating rail and a fixing rail attached to a face of a structure and spaced apart in parallel; a wall panel having spaced apart thereon at least one locating and positioning formation and at least one fixing formation; wherein the at least one locating formation is associated with the locating rail in such manner as to effect a locating engagement between the wall panel and the locating rail; the wall panel is positioned with the at least one fixing formation in proximity with the fixing rail; and the fixing formation is mechanically engaged to the fixing rail.
Other preferred features of the secondary wall system will be understood by analogy to those described in respect of the method of the first aspect of the invention.
For example, the fixing formation may be locked to the fixing rail and/ or the locating formation may be configured to have two functional configurations, a locating configuration in which it is adapted to facilitate relative movement of the wall panel and the face and a locking configuration in which it is adapted to effect a fixed engagement between the wall panel and the locating rail.
For example, the secondary wall system may comprise a plurality of panels mounted on the said rails and hence on the face of the structure.
For example in a first principal example embodiment as above described at least two rails are provided, disposed generally horizontally in parallel on the face, so as to comprise an uppermost rail and a lowermost rail, and the locating rail is either the uppermost or lowermost rail and the fixing rail is correspondingly either the lowermost or uppermost rail.
For example in a second principal example embodiment as above described at least three rails are provided, disposed generally horizontally in parallel on the face, so as to comprise at least an upper fixing rail and a lower fixing rail and an intermediate locating rail between the upper fixing rail and the lower fixing rail.
The invention additionally comprises a structure such as a tunnel or the like having a secondary wall system provided on a face of the structure comprising a plurality of panels mounted thereon according to the foregoing.
The key to the invention in all its aspects is not merely that the wall is a modular construction, but primarily that the system modules are particularly adapted for off-site construction and mere assembly in-situ. Advantages to the invention accrue both because of its underlying modularity and because of its particular simplicity of assembly. Panels and wall sections may readily be adapted to particular requirements. Different panels may have different properties.
Panels may for example have modified properties including but not limited to one or more of: visible surface finishes for aesthetic, information, safety or commercial purposes, including for example signage or advertising; noise reducing coatings or linings; environmentally protective coatings or linings such as waterproof coatings or linings; coatings or linings for fire protection; cut-out portions for the accommodation of secondary structures such as secondary signage and lighting; built in lighting structures and for example built in LEDs.
Brief Description of Drawings
The invention will now be described by way of example only with reference to figures 1-4 of the accompanying drawings in which: figure 1 shows a secondary wall assembly in accordance with the principles of the invention in front and side elevation; figure 2 shows the intermediate mounting rail arrangement shown as inset A in figure 1; figure 3 shows the bottom rail mounting arrangement shown as inset B in figure 1; figure 4 shows the top rail mounting arrangement shown as inset C in figure 1.
Detailed Description
An example of a rail and wall panel arrangement embodying the principles of the invention is shown in the figures.
The illustrated embodiment shows three wall panels mounted in position on an upper, a lower rail, and an intermediate rail between the upper rail and the lower rail.
In the example embodiment, the panels are planar and therefore adapted to provide a planar secondary wall on the face of a structure. This is an example only. The skilled person will readily understand that the principles of the invention could be applied to a primary wall in a structure such as a tunnel which is curved and thus presents a curved mounting face, with the panels being modified to define a complementarily curved shape In the illustrated example embodiment, three parallel rails are provided, comprising an upper intermediate and lower rail. This is an example only, and the skilled person would readily understand from this illustrative embodiment how to adapt the principles of the invention to embodiments with alternative arrangements of rail.
Much depends on the size of the panel and its design. Panels offering pure aesthetic qualities are likely to be much lighter than those offering particular secondary properties such as environmental or fire protection. It is possible to envisage two supporting rails or even a single longitudinal rail.
An example use is discussed herein in which the illustrated embodiment is provided as a secondary wall mounted on the face of a tunnel. The invention might be applicable to any scenario where it might be desirable to build a secondary wall, and in particular where some of the difficulties of on-site fabrication associated with the relative inaccessibility of a tunnel bore or a similar structure might arise. For example, similar considerations might apply to a system for the lining of railway and bridge arches to allow for their conversion into usable structures.
In an example method making use of the illustrated embodiment, an attachment system comprising an upper elongate rail (1) an intermediate elongate rail (3) and a lower elongate rail (5) are attached to a wall of a tunnel structure, so as to be evenly spaced apart horizontally and in parallel.
In the illustration of figure 1 a three panel section comprising three panels (11a, 11 b, 11c) is shown. Of course, in a practical system, any number of panels may be used to build up a suitable secondary wall. In the illustrated embodiment the panels (11a, 11b, 11c) are identical. While it will usually be advantageous for panels to be identically sized and shaped to the basic framework, it is a particular advantage of the invention that it lends itself to the use of panels that are pre-fabricated with different secondary finishes, that are pre-fabricated with cut-out structures etc. Each panel has been pre-fabricated off-site to include before it is brought to the site for assembly a series of attachment formations appropriately spaced apart on a rear surface of the panel to enable it to be fixed to the rails. The zones comprising the attachment formations are circled in figure 1 respectively as zone A on the intermediate rail (3), zone B, on the lower rail (5), and zone C, on the upper rail (1), and respectively presented in greater detail in the views on figures 2 to 4.
In each case, the attachment formation comprises a bracket (respectively 21, 31, 41) that includes a projecting or carriage portion (respectively 23, 33, 43) that is received in a channel defined by the respective rail (3, 5, 1).
The example system illustrated in the figures has three supporting rails. The top one is used to fix the top of the panel in place such that it seats in completely rigid manner. The other two provide additional support to take the pressure and suction sources of vehicle traffic in a tunnel. The method of fitment in the example is to lift the panel about the support points of the intermediate rail (3); to drop the panel such that the intermediate brackets (21) locate it on the rail; to fasten the bottom of the panel in position to the lower rail (2) on its lower brackets (31) such that the dead weight is now taken on the brackets, and then to fasten the top of the panel back to its upper support rail (1) by means of its upper brackets (41).
Other arrangements of attachment formation and sequence will readily suggest themselves to the skilled person while still being embodied in the principles of the invention and encompassed in the claims appended hereto.
The key to the invention in all its aspects is not merely that the wall is a modular construction, but primarily that the system modules are particularly adapted for off-site construction and mere assembly in-situ. The panels are provided with attachment formations before being presented for assembly at the face of the tunnel or other structure, in the particular preferred case having at least some of these attachment formations fabricated integrally as an off-site prefabricated construction.
The particular combination of locating and fixing formations, and the pre-assembly of the rails at the structural face, cooperate together to ensure that the attachment operation at the site is simplified.
Advantages to the invention accrue both because of its underlying modularity and because of its particular simplicity of assembly.
In particular, it can be noted that a system that lends itself to rapid assembly in-situ of panels pre-fabricated off-site is also likely to be amenable to the ready replacement of such panels, for example for repair or to provide a modified functionality. Thus, inherent advantages associated with modular systems can be exploited to a greater extent, and different requirements in different structures, and for example different requirements in different sections of a given structure such as a given tunnel can be readily accommodated.
An advantage of the off-site fabrication principle is that more complex structural features, for example including cut-outs, can be readily provided to accommodate complex shapes and secondary structures such as light and signage etc., without the need to modify panels on-site.
Another potential advantage of the off-site fabrication principle is that replacement of panels or removal for maintenance is quick and easy. Additionally, panels may be designed to be reversible within the panel frame, which might double the working life of the system and/or give an in-situ deployable secondary functionality.
