Construction workers can be required to access building structures, such as chimney structures, located in difficult-to-access locations, such as pitched roofs. In order to safely access these building structures for construction or repair, the workers typically utilize a variety of types of support systems to support themselves on the pitched roof surface.
For example, in order to access a house chimney for repair, a worker can utilize a conventional pipe staging or scaffolding system that includes tube-based scaffolding that extends around the outer perimeter of a chimney. Typically, the base of the scaffolding is secured to the house roof using fasteners, such as nails. The scaffolding carries a set of planks that also extend about the outer perimeter of the chimney. The planks allow the worker to walk about the chimney on a horizontal surface to access and repair all portions of the chimney.
Conventional staging systems suffer from a variety of deficiencies. For example, while the conventional pipe staging system provides the construction worker with a walking surface surrounding the chimney, the base of staging system is directly secured to the roof using nails or other fasteners. These fasteners can damage the structural integrity of the roof which can lead to water or other fluids to leaking into the house once the staging system has been removed. Further, the fasteners provide a relatively minimal level of support for the staging. In certain cases, with such a minimal level of fixation to the roof, the staging can shift or sway as the workers walk along the scaffolding planks. This can lead to the worker feeling relatively unsafe during a chimney repair.
By contrast to conventional roof support systems, embodiments of the present innovation relate to a support apparatus for use with an elongate structure, such as a chimney. In one arrangement, the support apparatus includes a base configured to extend along both sides of a pitched roof surface, a set of vertical supports secured to the base and configured to be secured to the chimney, and a set of platforms connected to the set of vertical supports and configured to at least partially extend about the perimeter of the chimney. With this arrangement, because the base extends substantially along the length of both sides of the roof surface, the base is configured to distribute the weight of the support apparatus and the workers along a relatively large surface area of the pitched roof surfaces. Accordingly, the base effectively secures the base to the pitched roof surface without relying on external fasteners, thereby minimizing damage to the roof. Additionally, with the vertical supports secured between the base and the platforms, and with the platforms secured to each other, the support apparatus provides a substantially stable, horizontal walking surface for the construction workers during chimney construction or repair. This configuration minimizes the risk of injury to the worker and allows the worker to safely handle their tools during the construction or repair, thereby minimizing the risk of damage to the structure or injury to workers on the ground as caused by dropped tools.
In one arrangement, a support apparatus comprises a first base portion having a first base portion element configured to be disposed on a first roof portion and a second base portion element configured to be disposed on a second roof portion and a second base portion having a first base portion element configured to be disposed on the first roof portion and a second base portion element configured to be disposed on the second roof portion. The support apparatus comprises a first set of vertical supports connected to the first base portion and a second set of vertical supports connected to the second base portion, each of the first set of vertical supports and the second set of vertical supports extending along a direction that is substantially parallel to an elongate structure. The support apparatus comprises a set of platforms connected to the first set of vertical supports and to the second set of vertical supports, the set of platforms configured to at least partially surround the elongate structure. Each platform of the set of platforms connected to a corresponding, adjacent platform of the set of platforms.
The foregoing and other objects, features and advantages will be apparent from the following description of particular embodiments of the innovation, as illustrated in the accompanying drawings in which like reference characters refer to the same parts throughout the different views. The drawings are not necessarily to scale, emphasis instead being placed upon illustrating the principles of various embodiments of the innovation.
Embodiments of the present innovation relate to a support apparatus for use with an elongate structure, such as a chimney. In one arrangement, the support apparatus includes a base configured to extend along both sides of a pitched roof surface, a set of vertical supports secured to the base and configured to be secured to the chimney, and a set of platforms connected to the set of vertical supports, as well as to each other, and configured to at least partially extend about the perimeter of the chimney.
The base 12 is configured to distribute the weight of the support apparatus 10 along a relatively large area in order to provide the support apparatus 10 with a relatively high level of stability. For example, the base 12 can include a first base portion 18 disposed in proximity to a first side portion of a chimney 17 and a second base portion 20 disposed in proximity to a second side portion of a chimney 17.
Each of the first and second base portions 18, 20 can include base portion elements that extend along a length relative to the chimney 17, such as along the length of a roof 15. For example, with additional reference to
With the base 12 having first and second base portion elements 22, 24, 26, 28 disposed on either side of pitched roof 15, the base portion elements 22, 24, 26, 28 are configured to distribute the weight of the support apparatus 10 along the surface area of the roof 15. The base 12, therefore is configured to balance any loads applied to the roof 15 via the support apparatus 10, including the weight of the support apparatus 10 itself and the shifting weight of any workers utilizing the support apparatus 10. Accordingly, the configuration of the base 12 allows the weight of the support apparatus 10 to secure the support apparatus 10 to the roof 15 without requiring additional fixation components. For example, with the configuration of the base 12, an operator is not required to mechanically affix the support apparatus 10 to a roof in a destructive manner, such as by using nails or screws.
The first and second base portion elements 22, 24, 26, 28 can be configured in a variety of ways. For example, each of the first and second base portion elements 22, 24, 26, 28 can be configured as a ladder of other grid-like structure having a series of rungs. In use, such a configuration allows a worker to scale the roof 15 to access the platforms 16 surrounding the chimney 17.
In one arrangement, with particular reference to the second base portion 20 in
As illustrated in
Each platform 44, 46 also includes a respective base portion securing mechanism 55, 57 having a corresponding holding element 54, 56 and locking element 58, 60. In one arrangement, each holding element 54, 56 is configured to receive a rung of the corresponding base portion element 26, 28 while each locking element 58, 60 is configured to secure the corresponding rung to the platform 44, 46. For example, each locking element 58, 60 can be configured as a spring loaded member that snaps over a rung to secure each corresponding base portion element 26, 28 within the holding element 54, 56 and to the ridge spanning device 42.
The connecting element 48 of the ridge spanning device 42 can be configured in a variety of geometries. For example, each connecting element 48 can be configured as having a curved or arched geometry extending from an apex location 62 (e.g., a hinged apex location 62) to platform connection locations 64, 66. With this geometry, and with reference to

In one arrangement, each of the vertical supports 70, 72, 74, 76 are adjustably connected to the base 12 by a corresponding foot element 78, 80, 82, 84 disposed at a first end of the vertical supports 70, 72, 74, 76. For example, foot elements 78 and 80 define a first set of foot elements that are configured to secure corresponding vertical supports 70 and 72 of the first set of vertical supports to the first base portion 18 and foot elements 82 and 84 define a second set of foot elements configured to secure corresponding vertical supports 74 and 76 of the second set of vertical supports to the second base portion 20. As an example, and with reference to
In the example shown, the foot element 78 includes a base engagement portion 86 configured to adjustably secure the vertical support 78 to the base 12. In one arrangement, the base engagement portion 86 includes a first sleeve 88 and a second sleeve 90 configured to capture adjacent rungs 97, 99 on the corresponding base portion element 26. In such an arrangement, when the first and second sleeves 88, 90 engage the rungs 97, 99, the base engagement portion 86 secures the interlocking foot element 78 as well as the vertical support 70 to the base 12. Further, the configuration of the first and second sleeves 88, 90 allows a user to adjust a position of the foot element 78 along axis 101 relative to the base portion element 26 or ladder in order to dispose the vertical supports about chimneys 17 having differently sized cross-sectional areas.
In one arrangement, the vertical support 70 couples to the interlocking foot element 78 via an adjustable mounting support 92. For example, the adjustable mounting support 92 includes a support portion 94 configured to receive the first end of the vertical support 70. The support portion 94 is rotatably coupled to the base engagement portion 86 to allow an assembler to rotatably adjust 96 the position of the vertical support 70 relative to the chimney 17. The support portion 94 is also linearly coupled to the to the base engagement portion 86 to allow an assembler to linearly adjust 98 the position of the vertical support 70 relative to the chimney 17.
In one arrangement, the set of vertical supports 14 are configured to be connected to the support platforms 16 via a set of cross beams 200, as illustrated in
In order to align the cross beams 200 as substantially square with the chimney 17, an assembler can utilize a placement tool system 100 as illustrated in
With collective reference to
After generating the lateral load, the assembler can connect the first and second clamp members 110, 112 to the base member 114 using corresponding first and second locking assemblies 120, 122 to limit or prevent lateral translation of the first and second clamp members 124, 126 relative to the base member 114. The assembler then further squares the placement tools 102, 104 using the pair of interconnection members 106, 108 as shown in
With reference to
In one arrangement, the set of support platforms 16 are connected to the cross beams 200, via first and second support fixtures 204, 206 associated with the cross beams 200. For example, as illustrated in
In one arrangement, the set of support platforms 16 are further secured to the set of vertical supports 14 with corner brackets 150 as illustrated in
In one arrangement, each end of the spanner platforms 140, 142 and each end of the corresponding filler platforms 144, 146 are configured with a locking system to secure abutting platforms together. For example,
In use, an assembler aligns the opposing ends of the platforms 140, 144 and rotates the latch 252 about hinge 260 and along direction 261, such as by pulling on handle 262. With such positioning of the latch 252, the assembler moves the filler platform 144 toward the spanner platform 140 along direction 264 to insert the receptacle elements 254 into the groove 256 and such that the base 258 supports the end of the spanner platform 140. The assembler then releases the latch 252 such that an engagement portion 266 enters an opening 268 defined by the receptacle elements 254. This engagement locks the platforms 140, 144 together, as shown in
The support apparatus 10 is configured to provide a substantially safe and solid walking surface for a user. For example, because the base 12 extends substantially along the length of both sides of the roof surface, the base 12 is configured to distribute the weight of the support apparatus and the workers along a relatively large surface area of the pitched roof surfaces. Accordingly, the configuration of the base 12 effectively secures the base 12 to the pitched roof surface without relying on external fasteners, thereby minimizing damage to the roof. Additionally, with the vertical supports 70, 72, 74, 76 secured between the base 12 and the platforms 140, 142, 144, 146, and with the platforms 140, 142, 144, 146 secured to each other, the support apparatus provides a substantially stable, horizontal walking surface for the construction workers during chimney construction or repair. This configuration minimizes the risk of injury to the worker and allows the worker to safely handle their tools during the construction or repair, thereby minimizing the risk of damage to the structure or injury to workers on the ground as caused by dropped tools.
In one arrangement, the support apparatus 10 forms part of a support apparatus system 200.
Initially, as shown in
Next, an assembler secures a set of lift ladders 304 to the locking location of the leveling platform 300. In one arrangement, as illustrated in
Returning to
The assembler can install a landing platform 312, such as placed on the roof above the eve. The landing platform 312 extends across a portion of the roof 30 in a substantially level manner (e.g., perpendicular to a horizontal reference), which allows the platform to receive equipment.
Next, the assembler disposes at least one egress ladder 314 on the roof. In one arrangement, multiple egress ladders can be disposed about the chimney and connected together using pipes placed through the rungs of the ladders to allow the assembler to walk around the chimney.
Next, the assembler places ridge spanning device 42 on both sides of the chimney 17. The assembler then locks base portion elements 12, such as 8′ sections of ladders, to the ridge spanning devices 42. Next, the assembler clamps placement tools 102, 104 (e.g., the chimney clamp system) to the sides of the chimney. As indicated in
Next, the assembler locks the first and second primary platforms and the first and second locking platforms to each other to create a substantially square and level work platform around the four sides of the chimney. The assembler then lock corner braces 15 between the platforms and the vertical supports, as indicated in
