Apparatus of passenger conveyor 1 described in this specification sheets is arranged on speedwalk between two different works etc. as object with the escalator between the different floor being erected at the works (also can be described as structure) comprising house (fabrication) with using level or mild gradient.In addition, floor of the present invention (hereinafter referred to as sliding floor) is arranged in building lower floor 2 and/or building upper floor 3, is namely arranged on the gangway of at least one party in two gangways of apparatus of passenger conveyor 1.In the present embodiment, the situation being arranged on building lower floor side for the sliding floor of escalator is described.
At escalator with in the speedwalk of mild gradient setting, because of vibration during earthquake, between building lower floor 2 and building upper floor 3, relative storey displacement can be produced.In the speedwalk arranged in the horizontal direction, when being arranged between two different buildings, relative displacement can be produced between two gangways of speedwalk.It should be noted that, about above-mentioned relative displacement and relative storey displacement, in this manual, what occur the length direction (direct of travel of step) along framework (Frame) 13 is described with the displacement of horizontal direction parallel.In addition, the relative displacement between two gangways is as comprising escalator and using with the upperseat concept of the relative storey displacement in the speedwalk of mild gradient setting.
As shown in Figure 1, apparatus of passenger conveyor 1 possess step 104, with the structure member such as the synchronization-moving handrail 105 of this step 104 and railing 106, wherein, this step 104 connects in the form of a ring, and between the gangway of the side be connected with the floor F1 of building lower floor 2 and gangway, bottom 102 and the gangway of the opposing party be connected with the floor F2 of building upper floor 3 and gangway, top 103, carry out loopy moving, this railing 106 is erected to the both sides of the Width being arranged on this step 104, forms the path of travel of handrail 105.It should be noted that, in this manual, the Width of step 104 is defined as vertical with the moving direction of step 104 and parallel with the pedal tread of step 104 direction (horizontal direction), and by along step 104 moving direction extend and the direction parallel with the pedal tread of step 104 is defined as depth direction.This depth direction is sometimes referred to as the length direction of framework described later (also referred to as main body frame) 13 or apparatus of passenger conveyor 1.
In addition, by the total length on the length direction of the structure member of railing 106 grade (namely from gangway, bottom 102, via lower curve path 104A, slant path 104B and upper curve path 104C until the total length of gangway, top 103) link into an integrated entity for lower horizontal portion 107A, the sloping portion 107B of the framework 13 of L and upper horizontal portions 107C, and be configured between the floor F1 of building the lower floor 2 and floor F2 of building upper floor 3.This framework 103 is such as made up of steel.
The supporting part (also referred to as beam body) 7 being fixed on upper side (F2 side, the floor) end of framework 13, can not to move and the mode that can not depart from integrally is fixed on the building structure 108 of upper side securely, forms the fixation side part 101A of framework 13 thus.In addition, the supporting part (also referred to as beam body) 7 being fixed on lower side (F1 side, the floor) end of framework 103 is placed in the floor F1 of building lower floor 2 with transitory state, forms the mounting side part 101B of framework 13 thus.Mounting side part 101B is formed at and makes to there occurs large relative storey displacement (relative displacement) between floor F1 and floor F2 because of earthquake etc., when making to there occurs relative displacement between the building structure of framework 13 and F1 side, floor and step part (also referred to as bearing beam) 2A, prevent loading side part 101B and depart from from the step part 2A of floor F1 and drop.In addition, by arranging mounting side part 101B, framework 13 can be prevented stressed on compression direction, and the power on this compression direction can be reduced.Therefore, the slipper 100 that can slide relative to the step part 2A of F1 side, floor is possessed at mounting part 101B place, side.
Next, with reference to Fig. 2 and Fig. 3, the structure of mounting side part 101B is described.
Framework 13 has main floor 4, the supporting part 7 of apparatus of passenger conveyor 1 has the first floor 5, the step part 2A of building lower floor 2 is provided with the second floor 5a.
Supporting part 7 is made up of L-shaped steel, and the limit 7v of the vertical of L-shaped steel is fixed on the end of framework 13, the limit 7h of the horizontal direction of L-shaped steel by screw rod 17 to be positioned on step part 2A for revocable state relative to building lower floor 2.According to this structure, supporting part 7 forms the sliding floor 100 that the second floor 5a of formation sliding floor is slided relative to building lower floor 2.Gap 12 is formed between supporting part 7 and the end face 2A2 by framework 13 side of step part 2A, when there occurs relative storey displacement (relative displacement) between floor F1 and floor F2, mounting side part 101B can carry out slide displacement relative to floor 14 (identical with the floor F1) side of step part 2A towards building lower floor 2 in the scope in gap 12.It should be noted that, screw rod 17 is rational height adjustment components of the rational height for adjusting supporting part 7.
As mentioned above, in the apparatus of passenger conveyor of the present embodiment, possesses the framework 13 that two ends are supported by the step part 2A be arranged on works floor, the end of at least one party of framework 13 is configured to load side part 101B, and is supported to and on the length direction of framework 13, can carries out relative displacement relative to step part 2A.
The upper surface on the first floor 5 is covered by the first floor panel 8a, and the surface (upper surface) of the first floor panel 8a becomes the walking surface of passenger.First floor 5 and the first floor panel 8a, along with relative storey displacement during earthquake, carry out relative displacement (slip) relative to step part 2A together with framework 13.
In the present embodiment, also there is the second floor (sliding floor) 5a, second floor 5a be arranged on be formed in framework 13 side between the first floor 5 and the floor of building side and the floor 14 of building lower floor 2, be set to slide relative to floor 14.
Second floor 5a possesses the second floor panel (also referred to as surface plate) 8b and strengthens structure 20.Strengthen structure 20 to be made up of floor enhancing part 6 and directing assembly 30, be arranged on step part 2A to support the back side of the second floor panel 8b.Second floor panel 8b and floor strengthen part 6 and are fixed to one another and form integral structure (integrative-structure), and floor strengthens part 6 and supported by directing assembly 30.Directing assembly 30 divides the guiding piece 30a of the 6 and pedestal 30b for loading also fixed guide 30a to form by keeping floor enhanced portion.Guiding piece 30a is arranged at the length direction of framework 13 both sides that floor strengthens part 6, is fixed on pedestal 30b by bolt 30d.
Floor strengthens part 6 and is arranged near the central authorities at the second floor panel 8b back side, for supporting the second floor panel 8b and suppressing bending of the second floor panel 8b.Enhancing structure 20 is configured to be had the first gap 9 and have the second gap 9a between the step surface 2A1 side of step part 2A on the length direction of framework 13 between framework 13 side.Specifically, on the length direction of framework 13, the both sides strengthening part 6 on floor are provided with gap, first gap 9 is arranged between floor enhancing part 6 and supporting part 7 or floor strengthens between part 6 and the first floor 5, and the second gap 9a is arranged on floor to be strengthened between part 6 and the step surface 2a1 of step part 2A.Thus, when framework 13 has carried out relative displacement relative to step part 2A at the length direction of framework 13, strengthen structure 20 and born the thrust pressure from framework 13 side and can move on step part 2A.
As shown in Figure 3, the second floor panel 8b be set to overlap building lower floor 2 floor 14 on and be formed in the floor i.e. surface of the first floor panel 8a of framework 13 side.Further, the second floor panel 8b is configured to slide towards the direction of side, floor 14 and the direction of the first floor panel 8a side.It should be noted that, width overlapping with floor 14 for the second floor panel 8b is set as B, and the width that the second floor panel 8b is overlapping with the first floor 8a is set as A.
In addition, the friction force (the first friction force) of the contact portion in the front of the back side of the second floor panel 8b and the first floor panel 8a is set smaller than the friction force (the second friction force) of the lower surface of pedestal 30b and the contact portion of step part 2A, and, second friction force is set to and is less than when earthquake, when there occurs relative storey displacement, supporting part 7 or the pushing of the first floor 5 strengthen the thrust pressure (pressing force) of structure 20.
When there occurs earthquake etc., if rock little, load side part 101B towards Fig. 2 arrow Y shown in direction move time, the supporting part 7 of apparatus of passenger conveyor 1 or the first floor 5 amount that movement is suitable with relative storey displacement the first gap 9 in.Now, due to the first friction force < second friction force, therefore the second floor 5a is motionless, and the first gap 9 between the first floor 5 and the second floor 5a diminishes.And, when there occurs the relative storey displacement being greater than the first gap 9 because of more massive rocking, the first gap 9 movement is further crossed on first floor 5, and now, the floor that the supporting part 7 of apparatus of passenger conveyor 1 or the first floor 5 push the second floor 5a strengthens part 6.Thus, the second floor 5a comprising the second floor panel 8b moves along the length direction of framework 13 towards the second side, gap 9, and the second gap 9a diminishes.It should be noted that, the sliding surface be formed on the second floor 5a is the lower surface of pedestal 30b.
As mentioned above, near the central authorities being arranged on the back side of the second floor panel 8b owing to floor to be strengthened part 6, and gap is provided with in both sides, therefore, it is possible to the relative storey displacement that the mode of floor damage can not be made to tackle building.Further, due to the slidably distance of the mounting side part 101B of apparatus of passenger conveyor 1 can be lengthened, therefore, it is possible to tackle large rocking in the mode that structure member such as framework 13 grade can not be made to damage.
In addition, as mentioned above, strengthen structure 20 by arranging at the dorsal part of floor panel, and the first gap 9 and the second gap 9a is set in both sides, therefore, compared with the situation only relying on the end of the second floor panel 8b to carry out supporting, bending of the second floor panel 8b can be suppressed.Thereby, it is possible to reduce the thickness of the second floor panel 8b, thus the difference of height of floor panel end can be reduced.Further, due to the slidably distance of mounting side part 101B can be lengthened, even if the length of the therefore floor panel (especially the second floor panel 8b) of the length direction of framework 13, also can prevent floor panel from bending at above-below direction.
Next, the action of the second floor 5a is described with reference to Fig. 2, Fig. 4 A to Fig. 4 C.It should be noted that, in the present embodiment, due to the second floor panel 8b and enhancing structure 20 are arranged to integrative-structure, therefore the second floor panel 8b is mobile with enhancing structure 20 one.
As shown in Figure 2, relative storey displacement is not occurring usually, the overlap length A of the second floor panel 8b of the second floor 5a and the first floor 5 or the first floor panel 8a (being referred to as the first side, floor 5 below) is greater than the size of maximum relative storey displacement (relative displacement) γ max and the size sum of the second gap 9a that the second floor panel 8b at least supposes on the length direction of framework 13.Specifically, according to formula 1, there is the mode of rich amount α to set overlap length A.
A=second gap 9a+ relative storey displacement γ max+ affluence amount α (formula 1)
The length B that second floor panel 8b is overlapping with the floor 14 of building lower floor 2 on the length direction of framework 13 is set as at least being greater than the first gap 9.Specifically, according to formula 2, there is the mode of rich amount α to set overlap length B.It should be noted that, the affluence amount α of the formula 1 and affluence amount α of formula 2 can be different.
B=first gap 9+ affluence amount α (formula 2)
Length A is set on the basis of the action of Fig. 4 A and Fig. 4 B that consider following explanation.Further, length B be consider to make the second floor panel 8b to there occurs the situation of position skew towards framework 13 side because passenger walks on the second floor panel 8b after be added with the length in the first gap 9 and set.
Fig. 4 A is the action specification figure of the second floor 5a, represent strengthen structure 20 be subject to the first floor 5 pressing and from state during usual shown in Fig. 2 along the state of direction shown by arrow Y movement among the second gap 9a.Now, think and there occurs the relative storey displacement suitable with the maximum relative storey displacement γ max supposed.
When framework 13 moves towards step surface 2A1 side, the part (main floor 5 or supporting part 7) abutted with enhancing structure 20 be arranged in framework 13 moves and abuts with enhancing structure 20 in the first gap 9, by this abutment portion with strengthen the abutting of structure 20, strengthen structure 20 and bear the thrust pressure from framework 13 side and move towards the second 9a side, gap.
In a situation shown in fig. 4 a, the gap (first gap 9 and the second gap 9a) strengthening structure 20 both sides disappears.Further, the second floor panel 8b and the first floor 5 stress the length adding the first gap 9 compared with length A1 and the A that folds.In addition, the length B1 that the second floor panel 8b is overlapping with the floor 14 of building lower floor 2 adds the length suitable with the second gap 9a.
Fig. 4 B is the action specification figure of the second floor 5a, represent the first floor 5 and framework 13 from the state of Fig. 4 A in the opposite direction (direction shown by arrow Z) mobile and from the state after position time usual moves the amount suitable with the maximum relative storey displacement γ max supposed further.Now, strengthen structure 20 and maintain position under Fig. 4 A condition.Therefore, to be formed between structure 20 and the first floor 5 and the first gap 9 and the second gap 9a and the suitable interval of relative storey displacement γ max sum strengthening.Further, the length A2 that the second floor panel 8b and the first floor 5 stress to fold has affluence and measures α.In addition, overlap length A during by setting usual as shown in Fig. 2 and formula 1, even if under the state (state shown in Fig. 4 B) that framework 13 and the first floor 5 leave the floor 14 of building lower floor 2 to greatest extent by the maximum relative storey displacement γ max of hypothesis, the overlap length A2 suitable with affluence amount α still can be retained between the second floor panel 8b and the first side, floor 5.
It should be noted that, in this condition, second floor panel 8b is in the state easily bent, but this state only may occur when there occurs the emergency state such as earthquake, therefore the possibility of this state continuance existence is very little, after there occurs this state, as shown in Figure 2 the second floor 5a can be moved to the position with the second gap 9a by maintainer etc.Or, also can, by arranging the elastic components etc. such as spring, make the second floor 5a be automatically moved to the position being formed with the second gap 9a.
Fig. 4 C is the action specification figure of the second floor 5a, represent the first floor 5 to have been carried out from state during usual shown in Fig. 2 towards the direction (direction shown by arrow Z) that the first gap 9 expands by relative storey displacement γ mobile after state.Now, between enhancing structure 20 and the first floor 5, the interval suitable with relative storey displacement γ max sum with the first gap 9 is formed with.Further, the length A3 that the second floor panel 8b and the first floor 5 stress to fold becomes the length after the length deducting relative storey displacement γ max, namely becomes and the second gap 9a and rich that measure α with suitable length.Now, also overlap length A3 can be retained between the second floor panel 8b and the first side, floor 5.
First gap 9 and the second gap 9a and above-mentioned gap 12 consider hypothesis maximum relative storey displacement γ max size (length) basis on set.That is, preferably the first gap 9 and the combined length of the second gap 9a and the size in above-mentioned gap 12 be set greater than or equal the size of maximum relative storey displacement (relative displacement) the γ max supposed.By as above setting the first gap 9 and the combined length of the second gap 9a and the size in above-mentioned gap 12, the displacement of the mounting side part 101B of framework 13 can not be hindered, and therefore, apparatus of passenger conveyor 1 and building side can not sustain damage.And, as mentioned above, by the combined length in the first gap 9 and the second gap 9a being set as the size equaling maximum relative storey displacement γ max and the gap 12 supposed, or be set greater than the size in relative storey displacement γ max and gap 12, apparatus of passenger conveyor 1 and building side can be avoided to sustain damage.
It should be noted that, the second floor panel 8b length B overlapping with the floor 14 of building lower floor 2 side can, when considering the position strengthening structure 20 and offset by the length suitable with relative storey displacement γ max further towards the first side, floor 5, adopt following method to set.
B=first gap 9+ relative storey displacement γ max+ affluence amount α (formula 3)
Thereby, it is possible to prevent from effectively producing gap between the floor 14 of the second floor panel 8b and building lower floor 2 side.
In addition, the first floor 5 also can not be set, and main floor 4 is extended, make main floor 4 double as the first floor 5.
Second embodiment
With reference to Fig. 5 and Fig. 6, the second embodiment involved in the present invention is described.Fig. 5 represents the floor section drawing of apparatus of passenger conveyor 1, Fig. 6 is the instruction diagram of the action of the second floor 5a of the present embodiment, represents that the first floor 5 has carried out state movement after from state during usual shown in Fig. 5 towards the direction (direction shown by arrow Z) that the first gap 9 expands by the maximum relative storey displacement γ of hypothesis.
In this configuration, the second floor panel 8b does not strengthen part 6 with floor and forms integrative-structure, but is configured to the second floor panel 8b and can strengthens part 6 relative to floor and carry out relative displacement.Strengthen structure 20 to be made up of floor enhancing part 6, the directing assembly 30 of the first embodiment is not set.Floor strengthens part 6 and is fixed on step part 2A by bolt 16.The object adopting bolt 16 to be fixed is the position skew in order to prevent floor from strengthening part 6.Fixing by what undertaken by bolt 16, floor strengthens the position that part 6 can maintain regulation, unless the supporting part 7 of apparatus of passenger conveyor 1 or the floor of the first floor 5 and the second floor 5a strengthen part 6 and collide, floor strengthens part 6 and is pressed and bolt 16 is ruptured.
In addition, the second floor panel 8b is fixed together by screw 18 and the first floor panel 8a.Thus, when the first floor 5 is moved along its length, the second floor panel 8b moves together with the first floor 5.Or, the second floor panel 8b also can not be set, but the floor 14 by the first floor panel 8a on the first floor 5 is extended to building lower floor 2, replace the second floor panel 8b with this.
