Abstract
Abstract A portable and relocatable support structure for a conduit, pipe, duct or other equipment extending above a roof has a concrete base from which extend a pair of upright members. A transverse support is attached to the upright members for receiving the conduit and a covering bracket extends over the supported conduit and is also attached to the upright members. The structure enables an adjustable positioning of the conduit and guards against an unintentional displacement of the conduit from the structure. The structure may be installed following the roofing operation. The support has application in any maintenance, retrofit or new roof application. The structure may be moved along the conduit to effect roof repairs beneath it.
Description
2~s,~
The invention is a portable, relocatable support structure for a conduit, walkway or other equipment which may be located on a roof.
Walkways, mechanical or gas pipes, ducts or other equipment are frequently located on top of flat roofs.
These conduits, equipment or other structures need to be supported above the roof surface in order to maintain the integrity of the roof structure. Traditionally, such support structures (hereinafter referred to as conduit supports) are either built into the roof or inappropriately placed on it which often results in damage to the watertight integrity of the roof structure.
Desirably, a conduit support structure for a roof should be portable so that it may be moved to effect a roof repair beneath it or near it. The conduit support desirably may be added or remo~ed without jeopardizing the roof assembly when equipment is either added or deleted. It should be capable of installation regardless of weather conditions that would otherwise hamper roof repair operations in relation to a fixed support structure. The device should be installable on any type of roof assembly. Its installation should not jeopardize a roof warranty which usually becomes invalidated if the roof is cut into by a person other than the original contractor or manufacturer. The structure should provide an adjustable support for the conduit so that the conduit may be supported at a desired height above the roof, and so that the conduit may be sloped or levelled, as desired, from one support to another, for example, to compensate for deck slope.
A preferred conduit support for this purpose should also provide stable support in expected weather conditions. For supporting a pipe, the structure should be able to accommodate structural loads, and longitudinal thermal expansion and contraction of the pipe. The ..
2~2~332 conduit should be secured within the support structure.
A preferred conduit support should be portable and relocatable on a roof, that is, their locations and number should allow for variants to suit any reasonable construction circumstance. This feature will reduce the amount of coordination required between various trades during construction activities.
Prior devices have not addressed these various needs. Frequently, prior support structures have been fixed in place in the roof structure, thus restricting future changes in roof conduit configurations and presenting the roofer with additional leak sources.
Prior devices lack height adjustability for the conduit so that the sloping of a conduit on a roof for drainage purposes, or for any other reason, is not facilitated.
Also, prior devices usually make no adequate provision for securing the conduit in place while allowing for expansion and contraction. Rather, the conduit is often just placed on top of a support so that it is vulnerable to displacement onto the roof, which may cause damage to the roof and to the conduit. Pipes attached to fixed supports will result in the thermal expansion and contraction forces being transferred to the points of attachment which usually results in damage to the supports or roofing system. Additionally, the installation of fixed conduit support structures may require the services of several workers from different trades, and to the extent that a structure can be installed by workers of a single trade, the contractor's job is simplified.
Accordingly, the invention addresses the various needs and problems aforementioned by providing a portable support structure for a conduit having a base preferably of concrete and a conduit support attached to the base.
The conduit support has spaced upright members attached 2~23~
to a transverse member and a covering bracket extending over the transverse member which is attached to the upright members to secure a conduit within the support structure.
S Brief Description of the Drawings Figure 1 is a perspective view of the invention having a transverse roller support member for the conduit.
Figure 2 is a cross sectional detail showing the lo assembly of the roller with the upright supports and covering bracket.
Figure 3 is a perspective view of the invention having a flat transverse support member for a duct or equipment.
Frequently, the roof of a building is utilized to support roof walkways and conduits such as gas pipes or ventilation ducts, and these walkways or conduits require some structural means of support. Permanent structures for supporting walkways and conduits on a roof have proven unsatisfactory because they present sites for potential roof failure and leakage. Also, if the walkway or conduit needs to be rerouted on the roof for some reason, the permanent supports do not provide the flexibility to make the required changes easily.
As shown in Fig. 1, the present invention is a portable support structure 10 that can be located on any surface of a finished roof to support a conduit 12. The support structure 10 has a base 13, preferably of concrete, which for most applications may be a readily available patio stone or paver, being about two feet square by about two inches thick. The base 13 provides ' ;
~3~2 resistance laterally and vertically. To provide an interface with the roof surface, the base 13 preferably has a water resistant insulating material 15 attached to its bottom surface. Alternatively, the base 13 may be set loose on the roof surface. A suitable insulating material is polystyrene foam. While dimensions of the base 13 may vary from one application to another, it will be apparent to the skilled person that the base must be of a size and weight to provide the required degree of stability to the structure 10 without damaging the underlying roof structure. A concrete base lo having a thickness of from about 2 inches to about 4 inches is preferred.
Extending from the top surface 17 of the base 13 are a pair of upright members 19. The upright members 19 are preferably of angled sheet metal having a short arm 20 which may be fastened to the base 13 by a nut and bolt 21 or other conventional means. It will apparent to the skilled person that a variety of materials may be used in place of the preferred angled sheet metal in construction of the support structure of the invention. The sheet metal of the upright members 19 is preferably of a thickness which allows a workman on site to drill holes through them in order to locate a trans~erse conduit support member 23 at the desired height. Of course, holes may be predrilled in the upright members 19. The insulating material 15 provides further rigidity to the base 13 and helps to distribute the load over a wide area, which helps protect the roof. The insulation elevated base 13 raises the support 10 above the roof drainage plan, thus discouraging rusting of the support 10 and deterioration of the concrete of the base 13.
Importantly, the insulating layer 15 insures that fasteners 21 penetrating the bottom of the concrete base 13 do not damage the roof membrane or surface.

Depending on the type of conduit 12 being supported, the transverse member 23 may be a roller 25 (Figs. 1 and 2) or a flat member 26 (Fi~. 3). The roller 25 is used in conjunction with a pipe 28 or other conduit 12 which may be subjected to thermal expansion and contraction.
Square or rectangular cross sectional ducting 29, on the other hand, does not generally require the roller support 25, so a flat member 26, as shown in Fig. 3, is appropriate.
The flat member 26 preferably has short legs 31 angled at either end of the member 26 for attachment to the upright members 19 by bolts and nuts 32 or other suitable fastening means. The roller 25 is preferably mounted on an axle 35 having threaded ends 36 for receiving nuts 37 (Fig. 2).
The support structure 10 has a covering bracket 41 which is sized to extend over the conduit 12 and is attachable to the upright members 19. The covering bracket 41 acts to retain the conduit in the support structure 10, which is important since unintentional displacement of the conduit 12 from the support structure 10 may lead to rupture of the conduit 12 or damage to the roof or both. Preferably, the covering bracket 41 has legs 43 extending downwardly from a transverse portion 44 with the legs 43 being attachable to the upright members 19, preferably by the same fasteners used to attach the transverse support member 23 to the members 19.
As seen from Fig. 2, a preferred means for attaching the roller 25, covering bracket 41 and upright members 19 together comprises an inner nut 46 which is tightened cooperatively with the outer nut 37 at either end of the axle 35 to secure the cover bracket 41 to the upright member 19. A washer 47 is preferably provided between the inner nut 46 and each roller end to facilitate .

movement of the roller 25 about the axle 35.
The invention provides a structure which enables the worker installing it to position the conduit 12 level with the roof or at a slope to the roof for drainage or other purpose. If the roof requires repair in the vicinity of the support structure 10, the structure 10 may ~e moved along the conduit and replaced when the repairs have been completed.
