Description

  The present invention relates to a fascia plate for a seismic isolation elevator.

The elevator's fisher plate has been established by the Building Standards Act as “the size from the car sill to the fisher plate should be 125 mm or less”. Ordinary fesher plates are attached to the building side, but in buildings with seismic isolation layers, the deformations in the seismic isolation layers are large, so they were fixed to the connecting frame attached to the elevator rail. . Previously, the maximum interlayer displacement of the seismic isolation layer was up to 350 mm. However, even if the maximum interlayer displacement is 500 mm, the dimension from the cage sill to the fisher plate is always 125 mm or less in the seismic isolation layer. Has come to be required by the market.
In the conventional seismic-isolated elevator fisher plate, a hole is made in the connecting frame attached to the elevator rail, and a laterally split fisher plate is attached. The upper rigidity is increased to prevent the deformation of the Fescher plate (see, for example, Patent Document 1).

JP 2004-99215 A

  In the conventional seismic-isolated elevator fascia plate, the amount of displacement transmitted to the fascia plate increases as the maximum displacement of the seismic isolation layer increases. For this reason, even a highly rigid fascia plate may be deformed during the seismic isolation operation. In that case, it cannot absorb only by bending of a Fescher plate, and there exists a possibility of causing a permanent deformation. In addition, since the force applied to the connecting frame increases as the maximum displacement amount increases, there is a risk that the strength of the connecting frame may decrease when a hole is attached to the connecting frame and a fesher plate is attached as in the prior art. . In addition, since the plate is attached so that the elongated hole is sandwiched through the collar, the dimension of the elongated hole increases as the maximum displacement of the seismic isolation layer increases. Even vibrations that sometimes occur can cause large rattles and generate noise. Further, in the case of a horizontally-structured Fesher plate as in the prior art, sufficient strength cannot be obtained simply by fixing the upper and lower sides of the connecting frame.

  The present invention has been made to solve the above-described problems, and has a structure in which a fascia plate can be attached without deviating from the provisions of the Building Standards Act and without impairing the strength of the rail connection frame. We provide a seismic-isolated elevator fascia plate.

In the elevator plate of the seismic isolation elevator according to the present invention, a plurality of connecting frames attached to the elevator rail are installed in the vertical direction at the seismic isolation part of the hoistway, and the fisher plate is used as the connecting frame so as to fill in between them. In what was attached, it was joined to the connection frame by welding, and provided with an attachment metal for attaching the Fescher plate.

  According to this invention, the connection frame attached to the elevator rail is installed at a plurality of locations in the seismic isolation part of the hoistway, and the attachment frame is joined to the connection frame by welding, so that the strength of the connection frame is not reduced. Since the rate is attached, destruction of the Fescher plate can be prevented. Moreover, even if a displacement occurs, the dimensions of the car sill and the fisher plate can be kept within the specified range of the Building Standard Law.

Embodiment 1.
FIG. 1 is a longitudinal sectional view of a hoistway of a seismic isolation elevator according to Embodiment 1 of the present invention, and FIG. 2 is a transverse sectional view of a seismic isolation elevator fascia plate according to Embodiment 1 of the present invention. 3 is an enlarged detailed view showing the portion E in FIG. 1, FIG. 4 is an exploded detailed view showing the portion C in FIG. 3, FIG. 5 is an enlarged detailed view showing the portion G in FIG. Is a front view of FIG. 5 as viewed from the direction of arrow B, FIG. 7 is an enlarged detailed view of a portion D of FIG. 1, and FIG. It is a perspective view which shows a part.

  In the figure, 4 is a building wall, 5 is a sill mounting bracket, 6 is an anchor bolt, 7 is an elevator rail, 8 is a connecting frame, 9 is a mounting bolt, 10 is a collar, 11 and 12 are fisher plate mounting brackets, 13 is Fescher plate which is divided vertically and has a vertically divided structure, 14 is a nut, 15 is a bolt, 16 is a reinforcement, 17 is an anti-vibration rubber, 18 and 19 are mounting brackets, 20 is a washer, 21 is a landing threshold, 22 is a toe guard.

  The connecting frame 8 fixes the four elevator rails 7 to each other, and is connected so as to form a square in the hoistway cross section as shown in FIG. A plurality of connecting frames 8 are installed only in the seismic isolation part in the vertical direction of the hoistway. The installation span is determined by the specifications of the floor, the strength of the Fescher plate 13, and the like. The fisher plate 13 is attached between the connecting frames 8 in a vertically split structure as shown in FIG. 8 by mounting bolts 9 fixed above and below the fisher plate 13. Long holes for fixing the connecting frame 8 and the mounting bolts 9 are formed on the upper and lower surfaces of the fisher plate 13. The size of each of the long holes is larger than the lateral displacement applied during the seismic isolation operation of the fescher plate 13. The length of the fescher plate 13 in the vertical direction (vertical direction) is slightly shorter than the vertical span to which the connecting frame 8 is attached. The upper part of the Fescher plate 13 is fixed by a mounting bolt 9 and a nut 14 so as not to move. The lower part of the fisher plate 13 is fixed by the mounting bolts 9 and the nuts 14, and is sandwiched between the fisher plate 13 and the connecting frame 8 through a long hole through the collar 10.

  The Fescher plate 13 is fixed in a state where it is suspended at the upper end, and the lower end is also fixed. However, since the collar 10 passes through the elongated hole, it can move along the elongated slot in the lateral direction. . Further, fixing holes are formed in the connecting frame 8 at the same pitch as that of the fisher plate 13, and are slightly larger than the diameter of the mounting bolt 9 so that the mounting bolt 9 can be easily passed. The mounting bolt 9 is fixed to one of the Fescher plates 13 at a total of six locations, three in the lateral direction (horizontal direction) and two in the vertical direction.

  The elevator rail 7 is fixed to the building wall 4 at the upper end and the lower end of the seismic isolation part, and the displacement at the time of the seismic isolation is 0, so that it can be completely fixed with the bolt 15. That is, since the upper and lower end of the seismic isolation layer 13 has a small amount of displacement during the seismic isolation operation, as shown in FIG. And the lower end is attached to the building wall 4 side by the anchor bolt 6 through the attachment metal 19, the bolt 15, and the nut 14.

  In addition, when there is a landing in the seismic isolation layer as shown in part G of FIG. 1, as shown in detail in FIGS. 5 and 6, a long hole 12a is formed in the sill attachment 5 to which the sill 21 of the landing is attached. Tighten the bracket 12 that has been opened. In addition, when there is a connecting frame 8 in the middle of the seismic isolation layer as shown in part E of FIG. 1, the details are shown in FIGS. 3 and 4, and an attachment metal attached to the connecting frame 8 by welding or the like. The fastener plate mounting bracket 11 having a long hole in 18 is fastened together. The specific structure will be described below.

  First, the attachment plate 18 is joined to the connecting frame 8 by welding or the like, so that the fescher plate 13 can be fixed without reducing the strength of the connecting frame 8.

  Secondly, as shown in FIG. 2 and FIG. 8, the fisher plate 13 has a U-shape that is bent only on the side surface. By bending, the rigidity is lower than that of the conventional structure. By making the deformation easier than in the conventional structure in this way, even if displacement occurs in the Fescher plate 13 during the seismic isolation operation, the amount of deflection of the entire Fesher plate increases, so that no permanent deformation occurs. I have to. Moreover, when the width | variety of the fisher plate 13 becomes large, the intensity | strength is ensured by joining the reinforcement 16. FIG.

  Thirdly, by fixing the anti-vibration rubber 17 between the fisher plate 13 and the fisher plate mounting brackets 11 and 12, noise caused by rattling or the like is not caused by vibration during normal operation. Further, since the collar 10 is sandwiched together with the anti-vibration rubber 17 so that the space is secured without being completely tightened, it is possible to move along the elongated hole when strong vibration or shaking occurs. Also, as shown in Fig. 2, the long hole is larger than the maximum displacement when shaking in the seismic isolation mode, but in the case of shaking in the vertical direction, the cage sill and the fesh In order to make the rate 13 distance 125 mm or less, the hole is smaller than the displacement. At this time, the Fescher plate mounting bracket collides with the bolt, but the shock-proof rubber 17 prevents the shock plate mounting brackets 11 and 12 from generating a strong impact load.

  Fourthly, the upper and lower fixings can be achieved by dividing the Fescher plate 13 in the horizontal direction so far into a vertically divided structure by dividing it vertically into a vertically divided structure. The required strength can be obtained only by
