Abstract
A tunnel structure includes a frame; a continuous plate fixed to the frame in order to protect passing-through pedestrians; supporting legs hinged to the frame; and a connecting section supported by the frame, the connecting section configured to enable the combination of multiple tunnel structures.
Claims11
An apparatus comprising:
- a modular pedestrian tunnel comprising:
- a first pedestrian tunnel module comprising:
- a rectangular frame having a perimeter defined by a first side and a second side each having a first length, and a third side and a fourth side each having a second length,
- a continuous plate fixed to the frame for protecting a pedestrian passing under the first pedestrian tunnel module,
- a first profiled element extending continuously along the first side of the frame and having a length equal to the first length,
- a second profiled element extending continuously along the second side of the frame and having a length equal to the first length, the second profiled element having a shape configured to interlock directly with a first profiled element of an adjacent pedestrian tunnel module,
- a third profiled element extending continuously along the third side of the frame and having a length equal to the second length,
- a fourth profiled element extending continuously along the fourth side of the frame and having a length equal to the second length, the fourth profiled element having a shape configured to interlock directly with a third profiled element of an adjacent pedestrian tunnel module, and
- a plurality of supporting legs hinged to the frame,
- wherein each of the four profiled elements is configured to withstand one or more of a bending moment and a twisting moment generated by a weight of at least the continuous plate,
- wherein the first profiled element comprises a structure extending along the first side of the frame and having an L-shaped cross-section having a first segment extending outward from the frame and a second segment extending from the first segment in a first direction, and
- wherein the second profiled element comprises a structure having a third segment extending outward from the frame and a fourth segment extending from the third segment in a second direction opposite the first direction.

An apparatus comprising:
- a modular pedestrian tunnel comprising:
- a first pedestrian tunnel module comprising:
- a rectangular frame extending along a first axis and a second axis, the first and second axes perpendicular to a third axis, the rectangular frame having a continuous cover fixed to the frame for protecting a pedestrian passing under the first pedestrian tunnel module, and
- a plurality of supporting legs hinged to the frame,
- wherein the frame comprises first and second flanges securing the cover therebetween, the first and second flanges extending along a direction parallel to the first axis beyond the cover and connected to each other by a connecting portion parallel to the third axis, thereby defining a top portion of a profiled element, the profiled element extending along the third axis and having a bottom portion connected to the top portion of the profiled element via a main body,
- wherein a first connector is connected to the top portion of the profiled element and extends continuously along a direction parallel to the second axis, the first connector having an L-shaped cross-section that is shaped to directly interlock with a first connector of an adjacent pedestrian tunnel module, the L-shaped cross-section comprising:
- a first segment that extends along the first axis away from the profiled element, and
- a second segment joined to the first segment and extending in a direction parallel to the third axis, and
- wherein a second connector is connected to the bottom portion of the profiled element and extends continuously along a direction parallel to the second axis, the second connector having an L-shaped cross-section that is shaped to directly interlock with a second connector of an adjacent pedestrian tunnel module, the L-shaped cross-section comprising:
- a first segment that extends along the first axis away from the profiled element, and
- a second segment joined to the first segment and extending in a direction parallel to the third axis,
- wherein the spacing between the first and second connectors along the third axis enables the profiled element to withstand one or more of a bending moment and a twisting moment generated by a weight of the continuous cover.
