Referring to fig. 1 to 5, the evacuation passage structure includes: a support part 10 and a tread body 20.
The support portion 10 includes a first support member 11 and a second support member 12 disposed at an interval. The treading body 20 is arranged on the first supporting component 11 and the second supporting component 12, the treading body 20 comprises a first side 21 and a second side 22 which are opposite, the first side 21 is fixed on the first supporting component 11, and the second side 22 is movably connected with the second supporting component 12.
It should be noted that the first support component 11 and the second support component 12 are arranged at intervals along the longitudinal direction of the bridge, and the interval between the two components is an expansion joint. As shown in fig. 1, the longitudinal direction is the X direction in the drawing, and the lateral direction is the Y direction in the drawing.
In the embodiment of the present application, since the support portion 10 includes the first support member 11 and the second support member 12 which are disposed at an interval, the treading member includes the treading body 20, and the treading body 20 is overlapped on the first support member 11 and the second support member 12, a pedestrian can walk on the treading body 20, and the treading body 20 forms a portion of the evacuation passageway on which the pedestrian treads. Because step on body 20 and include relative first side 21 and second side 22, first side 21 is fixed on first supporting component 11, second side 22 and second supporting component 12 swing joint, therefore, can make and step on body 20 and can satisfy the normal concertina movement of first supporting component 11 and second supporting component 12, and simultaneously, when the pedestrian walks on step on body 20, because second side 22 is connected with second supporting component 12, consequently, second supporting component 12 can provide support and pulling force for second side 22, make and step on body 20 and can bear great load, and make second side 22 be difficult for upwarping, and then reduce the possibility that appears stumbling the safety problem of pedestrian. That is, in the embodiment of the present application, the second side edge 22 is movably connected to the second support member 12, so that the evacuation passageway structure can satisfy the requirements of the normal telescopic movement and the safety performance of the bridge at the same time.
It should be noted that, in the embodiment of the present application, as shown in fig. 1, the first support assembly 11 may include two first supports 111 opposite to each other in the transverse bridge direction, and the second support assembly 12 may include two second supports 121 opposite to each other in the transverse bridge direction.
In the embodiment of the present invention, when the treading body 20 has different structures, the connection manner between the treading body 20 and the supporting portion 10 is also different, and specifically, there may be two types:
(1) as shown in fig. 1, the treading body 20 has a grid structure.
When the stepping body 20 is a grid structure, the grid structure can be light, so that the labor intensity of constructors is low when the stepping body 20 is installed.
In addition, when the stepping body 20 is a grid structure, as shown in fig. 3, the evacuation passageway structure may further include a first fixing member 30, a clip member 40, and a support member 50. The joint member 40 joint grid structure, support piece 50 are located between joint member 40 and the second supporting component 12, have the clearance between grid structure and the joint member 40, and joint member 40 and support piece 50 are fixed on the second supporting component 12 through first mounting 30.
Because joint 40 joint grid structure, support piece 50 is located between joint 40 and second supporting component 12, consequently, support piece 50 can play the supporting role to joint 40 for there is the clearance between grid structure and the joint 40. Because joint spare 40 and support piece 50 are fixed on second supporting component 12 through first mounting 30, consequently, make grid structure and second supporting component 12 be connected through first mounting 30, because there is the clearance between grid structure and the joint spare 40, consequently, when supporting part 10 produces deformation, grid structure can have certain activity space to the normal concertina movement of adaptation supporting part 10, can avoid grid structure extrusion joint spare 40 to make the problem appearance that joint spare 40 warp in addition.
In addition, in the embodiment of the present application, as shown in fig. 3, the grid structure may include first and second opposite snap arms 23 and 24, and the first and second snap arms 23 and 24 are located at the second side 22 of the pedal body 20.
Since the connecting portion 41 abuts against the supporting member 50, and both the connecting portion 41 and the supporting member 50 are fixed on the second supporting component 12 through the first fixing member 30, the supporting member 50 is located between the connecting portion 41 and the second supporting component 12, and at this time, the supporting member 50 can support the connecting portion 41. Since the first and second catching grooves 42 and 43 are connected to the connecting portion 41, respectively, the supporting member 50 is equivalent to supporting the first and second catching grooves 42 and 43.
At this moment, if the first supporting component 11 and the second supporting component 12 of the supporting portion 10 are deformed, the first clamping arm 23 on the second supporting component 12 can move in the first clamping groove 42, and the second clamping arm 24 can move in the second clamping groove 43, so that the normal telescopic movement of the supporting portion 10 can be adapted, and the first clamping arm 23 is prevented from damaging the first clamping groove 42 or the second clamping arm 24 is prevented from damaging the second clamping groove 43 when the supporting portion 10 is deformed. That is, by providing the supporting member 50, it can be avoided that the first engaging arm 23 damages the first engaging groove 42 and the second engaging arm 24 damages the second engaging groove 43 when the supporting portion 10 is deformed.
For example, as shown in fig. 3, the gap between the first catching arm 23 and the first catching groove 42 is L1.
It should be noted that, in the embodiment of the present application, the grid structure may be a steel grid structure, or a steel grid plate. Of course, the grid structure may also be a grid structure made of other metals, such as iron, and the embodiments of the present application are not limited herein.
In addition, in this embodiment of the application, the first engaging groove 42 includes a first groove wall and a second groove wall that are opposite to each other, a distance between the first groove wall and the second groove wall is greater than a width of the first engaging arm 23, and the width of the first engaging arm 23 is a distance between two opposite surfaces of the first engaging arm 23 along a direction from the first groove wall to the second groove wall.
The second clamping groove 43 includes a third groove wall and a fourth groove wall which are opposite to each other, the distance between the third groove wall and the fourth groove wall is greater than the width of the second clamping arm 24, the width of the second clamping arm 24 is along the direction from the third groove wall to the fourth groove wall, and the distance between two surfaces of the second clamping arm 24 which are opposite to each other is the same as the distance between the two surfaces of the second clamping arm 24.
Since the distance between the first and second groove walls of the first clamping groove 42 is greater than the width of the first clamping arm 23, when the first clamping arm 23 is located in the first clamping groove 42, the first clamping arm 23 can have a certain moving space in the first clamping groove 42. Similarly, when the second catching arm 24 is located in the second catching groove 43, the second catching arm 24 may have a certain moving space in the second catching groove 43. At this time, when the grid structure is mounted on the second support member 12 by the engaging member 40, if the first engaging arm 23 or the second engaging arm 24 in the grid structure is displaced, the first engaging arm 23 and the second engaging arm 24 can still be located in the first engaging groove 42 and the second engaging groove 43, respectively. That is, by setting the distance between the first groove wall and the second groove wall to be greater than the width of the first engaging arm 23, and setting the distance between the third groove wall and the fourth groove wall to be greater than the width of the second engaging arm 24, when the first engaging arm 23 or the second engaging arm 24 in the grid structure is displaced, the grid structure can still be installed through the engaging member 40.
In addition, if supporting part 10 produces deformation because the effect of expend with heat and contract with cold or other load effects, at this moment, second supporting component 12 drives first draw-in groove 42 and second draw-in groove 43 and removes, because first joint arm 23 can have certain removal space in first draw-in groove 42, second joint arm 24 can have certain removal space in second draw-in groove 43, consequently, first joint arm 23 can not directly collide with first draw-in groove 42, second joint arm 24 can not directly collide with second draw-in groove 24, thereby can avoid because the deformation of supporting part 10, lead to first joint arm 23 and second joint arm 24 to collide with first draw-in groove 42 and second draw-in groove 43 respectively, make first draw-in groove 42 and the impaired problem of second draw-in groove 43 appear. That is, by setting the distance between the first groove wall and the second groove wall to be greater than the width of the first engaging arm 23, and setting the distance between the third groove wall and the fourth groove wall to be greater than the width of the second engaging arm 24, it is also possible to avoid the problem that the engaging member 40 is damaged when the support portion 10 is deformed.
For example, as shown in fig. 3, the distance between the first and second slot walls is L2, the width of the first snap-in arm 23 is L3, and L2 is greater than L3.
For another example, when the first support member 11 and the second support member 12 which are spaced apart form a straight line, the distance between the first groove wall and the second groove wall is greater than the width of the first engaging arm 23, and the distance between the third groove wall and the fourth groove wall is greater than the width of the second engaging arm 24, at this time, the first engaging arm 23 and the second engaging arm 24 in the grid structure may be respectively located in the first engaging groove 42 and the second engaging groove 43 in the engaging member 40. When the first supporting component 11 and the second supporting component 12 which are arranged at intervals form a bending structure, namely, when a turning part occurs, because the positions of the first clamping arm 23 and the second clamping arm 24 in the grid structure cannot be changed, the first clamping arm 23 and the second clamping arm 24 respectively deviate relative to the first supporting component 11 and the second supporting component 12, at this time, the first clamping arm 23 can still be located in the first clamping groove 42, and the second clamping arm 24 is located in the second clamping groove 43.
In addition, in the embodiment of the present application, the first fixing member 30 may be a bolt, and the supporting member 50 may be at least one of a spacer and a nut.
As shown in fig. 3, when the first fixing member 30 is a bolt and the supporting member 50 is a cushion block, at this time, the cushion block may be placed on the second supporting member 12, then the connecting portion 41 of the engaging member 40 is placed on the cushion block, wherein both the connecting portion 41 and the cushion block of the engaging member 40 may be provided with a through hole, a bolt shank of the bolt passes through the connecting portion 41 and the cushion block, respectively, and passes through the second supporting member 12, and then the tightening nut 31 is tightened on the bolt shank, so that the connecting portion 41 and the cushion block are fixed on the second supporting member 12 by the bolt.
Because the cushion can play the supporting role to connecting portion 41, at this moment, first joint groove 42 and second joint groove 43 that are connected with connecting portion 41 respectively are equivalent to by the cushion pad for there is the clearance between first joint groove 42 and the first joint arm 23, there is the clearance between second joint groove 43 and the second joint arm 24.
It should be noted that the second support member 12 includes a first surface and a second surface opposite to each other, and the height of the first surface is greater than that of the second surface in the gravity direction. At this time, when the connection portion 41 and the spacer are fixed to the second support member 12 by bolts, the connection portion 41 and the spacer may be placed on the first surface first, that is, the connection portion 41 and the spacer are fixed in a direction from top to bottom.
As shown in fig. 5, when the first fixing member 30 is a bolt and the supporting member 50 is a nut, in this case, when the connecting portion 41 and the supporting member 50 are fixed to the second supporting member 12 by the bolt, the bolt shaft of the bolt may be inserted through the second supporting member 12 in a direction in which the second surface of the second supporting member 12 faces the first surface, i.e., in a direction from bottom to top, and then the supporting member 50, i.e., the nut, may be mounted on the bolt shaft, and the nut may be tightened. Then, the coupling portion 41 is fitted to the bolt shank, and finally, the tightening nut 31 is fitted to the bolt shank and the tightening nut 31 is tightened.
Since the evacuation passageway may be located on the bridge, at this time, the evacuation passageway is located in the air as an equivalent, at this time, when the first fixing member 30 is a bolt and the supporting member 50 is a nut, the first fixing member 30 may be fixed on the second supporting member 12 in advance through the supporting member 50 before the aerial work, and then, during the aerial work, the constructor only needs to perform the work on the first surface of the second supporting member 12, so that the construction difficulty may be reduced.
It should be noted that, in the embodiment of the present application, the first fixing member 30 may also be other devices, such as a pin, and the embodiment of the present application is not limited herein with respect to the type of the first fixing member 30.
