(13) FIG. 1 depicts an end view of an embodiment of an apparatus including an arch-support system 102.

(14) Referring to a general embodiment as depicted in FIG. 1, the apparatus includes (and is not limited to) a synergistic combination of the arch-support system 102 and a rail assembly 120.

(15) The arch-support system 102 is configured to support an archway 900 above a work surface 902 during construction of the archway 900. The rail assembly 120 is configured to selectively receive and support the arch-support system 102. This is done in such a way that the rail assembly 120, in use, supports the arch-support system 102 once the rail assembly 120 selectively receives the arch-support system 102.

(16) In accordance with an embodiment, the arch-support system 102 includes a synergistic combination of (A) an arch-support section 116 configured to securely support construction of the archway 900, and (B) a telescoping base section 104 configured to move the arch-support section 116 relative to the archway 900. The rail assembly 120 is configured to selectively receive and support the telescoping base section 104 in such a way that the rail assembly 120, in use, supports movement of the telescoping base section 104 relative to the archway 900 once the rail assembly 120 selectively receives the telescoping base section 104.

(17) More specifically, referring to the embodiment as depicted in FIG. 1, the arch-support system 102 includes (and is not limited to) a synergistic combination of a telescoping base section 104, an intermediate section 110, an arch-support section 116, and a rail assembly 120.

(18) With reference to all of the FIGS., and starting with FIG. 1, the arch-support system 102 is configured to support an archway 900 above a work surface 902 during construction of the archway 900 while allowing unimpeded movement below the archway 900 (such as, traffic or water flow) during construction of the archway 900. The archway 900 is to be constructed over (above) a work surface 902. The arch-support system 102 is configured to require a relatively shorter set-up time, and a relatively shorter demobilization time after completion of the construction of the archway 900. The arch-support system 102 is configured to allow sectional construction of a length of the archway 900. The arch-support system 102 is configured to allow the archway 900 to be curved and/or to change grade as well. The arch-support system 102 is modular and may be constructed in a desired length, with additional sections that may be attached to each other to allow construction of longer instances of the archway 900. The arch-support system 102 is configured to provide modular components to facilitate transportation. The arch-support system 102 is configured to assist in the construction of the archway 900 forming various radiuses, heights, lengths, curvatures and/or formed tunnels positioned underneath the archway 900. The arch-support system 102 may include rolled steel structural elements filled in with either steel plate and/or fine mesh expanded metal screening or a combination of both. This is to ensure that tools, materials or construction debris do not fall under the arch-support system 102 onto the work surface 902 positioned directly below the archway 900. Preferably, each section of the arch-support system 102 includes removable hand railings that may have expanded metal screening (or any other equivalent material or system) positioned between the structural elements (to ensure that tools, materials or construction debris do not fall under the arch-support system 102). Preferably, the arch-support system 102 includes hand railings that may be removed from the arch-support system 102 to allow the arch-support system 102 to be moved in order to assist in the construction of the next section of the archway 900, or for removal from the construction site after completion. The arch-support system 102 is configured to be movable for building free-standing archways. The arch-support system 102 is configured to support the placement of the blocks of the archway 900 until the key block is positioned in place. Once the key block is placed, the archway 900 becomes self-supporting, and the arch-support system 102 may be moved away from the archway 900. The arch-support system 102 is configured to be lowered and moved to the next position, and raised toward a section of the archway 900 to be constructed, so that construction work may continue on the next section of the archway 900.

(19) Referring to the embodiment as depicted in FIG. 1, the telescoping base section 104 is also called a lift base telescoping section. The telescoping base section 104 has an upper base section 106 (as depicted in FIGS. 3, 4, 5 and 6) and a lower base section 108 (as depicted in FIGS. 3, 4, 5 and 6) that is spaced apart from the upper base section 106. The lower base section 108 is configured to be securely mounted to the work surface 902. This is done in such a way that the telescoping base section 104 extends upwardly from the work surface 902 once the lower base section 108 is securely mounted to the V-shaped rail assembly 120 positioned on the work surface 902. Preferably, the telescoping base section 104 includes a locking device which is depicted in FIG. 5 as any one of or both the safety lock assembly 142 and the manual and lockable safety shut off valve 144 configured to prevent accidental movement (lowering, raising, vertical movement and/or horizontal movement) of the telescoping base section 104 during the construction of the archway 900 (in the event of a component failure and/or human error). A combination of safety lock assemblies and manual and lockable safety shut off valves are configured to prevent accidental movement of the telescoping base section during the construction of the archway.

(20) Referring to the embodiment as depicted in FIG. 1, the intermediate section 110 has an upper intermediate section 112 (as depicted in FIGS. 3, 4, 5 and 6) and a lower intermediate section 114 (as depicted in FIGS. 3, 4, 5 and 6) that is spaced apart from the upper intermediate section 112. The lower intermediate section 114 is configured to be securely affixed to the upper base section 106 of the telescoping base section 104. This is done in such a way that the intermediate section 110 extends upwardly from the telescoping base section 104 once (A) the lower intermediate section 114 is securely affixed to the upper base section 106 of the telescoping base section 104, and (B) the lower base section 108 is securely mounted to the work surface 902.

(21) Referring to the embodiment as depicted in FIG. 1, the arch-support section 116 is configured to be securely affixed to the upper intermediate section 112 of the intermediate section 110 (as depicted in FIGS. 1 and 2). This is done in such a way that the arch-support section 116 is spaced apart from the work surface 902 once the arch-support section 116 is securely affixed to the upper intermediate section 112 of the intermediate section 110. The arch-support section 116 is configured to securely support construction of the archway 900 in such a way that the arch-support section 116 is removable from the archway 900 once construction of the archway 900 is completed and the archway 900 is self-supporting. The telescoping base section 104 and the intermediate section 110 are configured to be combined in such a way that the telescoping base section 104 and the intermediate section 110 hold and support the arch-support section 116 in position relative to the archway 900. The weight of the archway 900 is received by the arch-support section 116. The weight of the archway 900 and the arch-support section 116 is, in turn, received by the combination of the telescoping base section 104 and the intermediate section 110. Preferably, the arch-support section 116 is configured to be arched (curved). More preferably, the arch-support section 116 is configured to be arched (curved) in such a way that the arch-support section 116 (in use) matches the curvature of the archway 900. Preferably, the arch-support section 116 is configured to match an archway radius of the archway 900. The archway 900 and the arch-support section 116 (to be fully constructed) are held and supported in position (the raised position above the work surface) while the archway 900 (or the section of the archway 900) is under construction. Once a section of archway 900 is completed, the telescoping base section 104 is configured to lower the arch-support section 116 away from the archway 900, and then the telescoping base section 104 may be removed (rolled out and away) from the archway 900. Then, an additional section of the archway 900 may be constructed, or the telescoping base section 104 (and other components, etc.) may be removed from the construction site. Preferably, the arch-support section 116 is fabricated to produce a desired arch size. Preferably, the arch-support section 116 is configured to be bolted (affixed) to the upper intermediate section 112 of the intermediate section 110. The arch-support section 116 is configured to (A) match the shape of the archway 900, and (B) hold or support the required load of the archway 900 until a section of the archway 900 is completed and self-supporting.

(22) In accordance with the embodiments as depicted in FIGS. 1 and 2, two instances of the telescoping base section 104 are spaced apart from each other (and face each other), and two instances of the intermediate section 110 are spaced apart from each other (and face each other). The arch-support section 116 is configured to be connected to (affixed to), and to span across, the two instances of the intermediate section 110 that are spaced apart from each other. In accordance with an option, the telescoping base section 104 includes spaced-apart telescoping base sections 104, and the arch-support section 116 is configured to be connected to (affixed to), and to span across, the spaced-apart telescoping base sections 104.

(23) In accordance with an embodiment as depicted in FIG. 5, the apparatus is adapted such that spaced-apart lift actuators 118 (also called hydraulic lift cylinders or spaced-apart lift assemblies, which may be either a single acting cylinder or a double acting cylinder) are affixed to the telescoping base section 104. This is done in such a way that the spaced-apart lift actuators 118 are configured to move the telescoping base section 104 along any one of an upward direction and a downward direction relative to the work surface 902 once the spaced-apart lift actuators 118 are affixed to the lower base section 108 of the telescoping base section 104.

(24) In accordance with the embodiments as depicted in FIGS. 1-6, the apparatus is adapted such that a rail assembly 120 is configured to selectively receive and support the telescoping base section 104. This is done in such a way that the rail assembly 120, in use, supports the telescoping base section 104 once the rail assembly 120 selectively receives the telescoping base section 104. Preferably, the rail assembly 120 is configured to contact and extend along the work surface 902. This is done in such a way that the rail assembly 120 extends along the work surface 902 underneath the archway 900 once the rail assembly 120, in use, contacts the work surface 902. Preferably, the rail assembly 120 forms (includes) V-shaped spaced-apart rails. The rail assembly 120 is configured to support and maintain the telescoping base section 104 in the correct (desired) position underneath the archway 900. The rail assembly 120 may be positioned by being bolted (connected) to a concrete base, by being fixedly mounted on rig mat-type supports, or any equivalent system. Preferably, the telescoping base section 104 forms or provides a corresponding V-shaped groove configured to make positive contact with the V-shaped rails of the rail assembly 120. In this manner, the telescoping base section 104 is positioned in a stationary position (relative to the work surface) on the rail assembly 120 (that is, once the telescoping base section 104 is lowered onto and received by the rail assembly 120). Generally, the telescoping base section 104 is configured to selectively mate with the rail assembly 120 in such a way that the telescoping base section 104 is selectively maintained in a stationary position relative to the rail assembly 120.

(25) In accordance with the embodiments as depicted in FIGS. 1-6, the apparatus is adapted such that spaced-apart wheels 122 are affixed to the lower base section 108 of the telescoping base section 104. The spaced-apart wheels 122 are configured to make rolling engagement with the rail assembly 120 (as depicted on the right-hand side of FIG. 3). This is done in such a way that the spaced-apart wheels 122, in use, permit horizontal rolling movement of the telescoping base section 104 along the rail assembly 120 once the spaced-apart wheels 122 engage the rail assembly 120. Preferably, the spaced-apart wheels 122 are attached to the spaced-apart wheel lift actuators 134 that are supported by the telescoping base section 104. The spaced-apart wheel lift actuators 134 are configured to respectively lower and raise the spaced-apart wheels 122 relative to the rail assembly 120. The spaced-apart wheels 122 are configured to be lowered (moved relative to) toward the rail assembly 120. The spaced-apart wheels 122 may be affixed to (mounted to) spaced-apart shafts and bushings 135 (also called spaced-apart support bushings and thrust bearings, as depicted in FIG. 3, and in detail drawing of FIG. 8. This arrangement allows the selective movement of the telescoping base section 104 relative to the archway 900 (when needed) into a predetermined position, thereby allowing or facilitating the construction of, for instance, a section of the archway 900, and/or allowing or facilitating the selective movement of the telescoping base section 104, for instance, for the construction of other (additional) sections of the archway 900 (as needed). When the telescoping base section 104 has been positioned at a desired location (along the rail assembly 120), the spaced-apart wheels 122 are lifted away from the rail assembly 120, and the telescoping base section 104 may then settle onto (and be supported by) the rail assembly 120 (which preferably includes a V-shaped spaced apart rails) in a relatively stationary position (relative to the work surface). In this manner, the telescoping base section 104 is securely locked in a stationary position relative to the archway 900. Preferably, the spaced-apart wheels 122 are configured to be locked in such a way that the spaced-apart wheels 122 are lifted away from the rail assembly 120 and the telescoping base section 104 contacts and rests on the rail assembly 120.

(26) In accordance with the embodiments as depicted on the left-hand side of FIG. 3, the apparatus is adapted such that the spaced-apart wheels 122 are configured to be locked. This is done in such a way that once the spaced-apart wheels 122 are locked, the telescoping base section 104 is stationary relative to the rail assembly 120. The spaced-apart wheels 122 are also configured to be unlocked (as depicted on the right-hand side of FIG. 3). This is done in such a way that once the spaced-apart wheels 122 are unlocked, the telescoping base section 104 is mobile relative to the rail assembly 120.

(27) In accordance with the embodiments as depicted in FIGS. 1, 2, 4 and 6, the apparatus is adapted such that a bracing assembly 124 (also called a hydraulic bracing cylinder and pivot arms) is configured to be coupled to the telescoping base section 104. The bracing assembly 124 is configured to brace the telescoping base section 104 against a stationary section of the archway 900 (as depicted in FIGS. 1 and 2). This is done in such a way that the bracing assembly 124, in use, prevents the lateral movement of the telescoping base section 104 relative to the work surface 902. The bracing assembly 124 is affixed to the side sections of the telescoping base section 104. The bracing assembly 124 is configured to position the telescoping base section 104 relative to the archway 900. The bracing assembly 124 is configured to prevent lateral movement of the telescoping base section 104 during construction of the archway 900.

Referring to the right-hand side of FIG. 3, the spaced-apart wheel lift actuators 134 have moved the spaced-apart wheels 122 toward (and into contact with) the rail assembly 120. Alternatively, the spaced-apart wheel lift actuators 134 may be replaced with spaced-apart bushings 135 (also called support bushings and thrust bearings), if so desired. The spaced-apart bushings 135 are not configured to move (directly move) the spaced-apart wheels 122 relative to the rail assembly 120, or relative to the work surface.

(33) Preferably, the spaced-apart lift actuators 118 are affixed to the lower base section 108 of the telescoping base section 104.

Preferably, the spaced-apart wheels 122 are configured to be respectively pivoting or rotatable about a longitudinal axis that extends through the spaced-apart wheel lift actuators 134. Alternatively, the spaced-apart wheels 122 may be mounted to spaced-apart bushings 135 (as depicted in FIG. 3 and in the detail drawing of FIG. 8).

(38) The telescoping base section 104 further includes vertically-extending spaced-apart telescoping tubular sections 136. The vertically-extending spaced-apart telescoping tubular sections 136 each includes an outer tube section 138 and an inner tube section 140 (which is also called a threaded inner tube section). The inner tube section 140 may include a threaded inner tube section or a grooved inner tube section, etc. The inner tube section 140 and the outer tube section 138 are threadably engaged with each other. In accordance with an option, the inner tube section 140 includes an unthreaded inner tube section 141 or a grooved inner tube section.

(39) A safety lock assembly 142 (also called a lock nut or a split lock nut) is provided with each of the vertically-extending spaced-apart telescoping tubular threaded sections 136.
