Description

The present invention relates to elevator cars and elevator installations.

In recent years, the concentration of population in urban areas has led to an increase in the number of high-rise buildings. Along with this, there is an increasing demand for high-speed and large-capacity elevator systems. In order to increase the speed of the elevator system, increase the capacity of the elevator system, reduce the load on the rope, etc., there is a demand for a lighter elevator car.

As a means of reducing the weight of elevator cars, the application of fiber-reinforced plastics, which are lighter than steel used for structural members, is being studied. Conventional elevator cars employ a structure in which a box-shaped car room is placed on a steel car frame made up of beams and columns.

In this conventional structure, when a load due to a load acts on a position deviated from the center of gravity of the elevator car (eccentric load), a large bending moment acts on the columns of the car frame. Therefore, it was necessary to reinforce the columns in order to keep the amount of deflection of the columns below the standard value.

If the structural members of the elevator car are made of fiber-reinforced plastic, following the conventional structure, it will be necessary to reinforce the pillars to withstand the bending moment. Further weight reduction was difficult.

Patent Literature 1 discloses an elevator car that uses fiber-reinforced plastic and integrates the pillars of the car frame and the walls of the car room in order to withstand the bending moment due to the eccentric load. In the structure described in Patent Literature 1, reinforcing spars functioning as columns are arranged at the center of two opposing car walls, respectively.

As a result, the load on the reinforcing spar increases, and it becomes necessary to increase the thickness of the reinforcing spar, making further weight reduction difficult. Another problem is that as the capacity of the elevator car is increased and the distance between the reinforcing spars increases, the load on the reinforcing spars increases.

Patent Literature 2 discloses a structure in which ropes are used to support a plurality of locations on the outer periphery of a car floor of an elevator car to reduce the load on the car frame. However, in the structure described in Patent Document 2, a separate rope guide and a rope guide supporting member for guiding the rope from the top of the elevator car to the car floor are required, leading to an increase in the weight of the elevator car.

As described above, in the conventional elevator car, the weight of the elevator car increases due to the provision of reinforcing members to withstand the weight of the elevator car, the load, etc., and the members to realize the structure to withstand the load. There was a problem.

One support member 4 is provided for each of the vertex portions 24 , and in the structure of the elevator car 100 shown in FIGS. It is called a vertex portion 24 that

The pillars 12 arranged at the corresponding vertex portions 24 are called corresponding pillars 12 . As shown in FIG. 4, four support members 4, one end of which is fixed to the rope connection part 1 at the support member fixing position 25, are stretched toward the corresponding pillars 12, and the pipe holes of the corresponding pillars 12 are stretched. and support the corresponding apex 24 .

Here, the range of the vertex portion 24 includes not only the vertex of the car floor 3 but also the periphery of the vertex. In FIG. 2, the car floor 3 is quadrangular in plan view, but it may be a convex polygon having 3 or 5 or more vertices. Here, a convex polygon is a polygon whose interior angles are all less than 180°. A vertex refers to a vertex forming a convex polygon, and a vertex part refers to a vertex and its periphery. Each support member 4 supports each vertex 24 of the convex polygon.

The form of the support member 4 between the rope connecting part 1 and the pillar 12 may be, for example, a form in which the rope connecting part 1 side is one and the pillar 12 side is branched into a plurality of parts. Alternatively, the rope connecting component 1 side may be branched into a plurality of branches, and the pillar 12 side may be a single branch. Further, a configuration in which a plurality of support members 4 support one vertex 24 may be adopted.

If one support member 4 is provided for each vertex 24 as in this embodiment, the number of fastening points of the support member 4 to the car floor 3 is reduced, and design and manufacture are facilitated. can have a simple structure. In this embodiment, the support member 4 comprises a rope enmeshed with a plurality of fibers and fasteners 8 fixed to the ends of the rope.

The fastening portion 8 is a screw shaft having a cylindrical shape and having a threaded side surface. The support member 4 and the rope connection component 1 are connected by fixing the fastening portion 8 to the rope connection component 1 . The portion between the fastening portions 8 of the support member 4 is not limited to a rope.

The fixing part between the fastening part 8 and the rope connecting part 1 may be a screw hole provided in the rope connecting part 1 and the fastening part 8 attached to the screw hole. In addition, a through hole is provided in the rope connecting part 1 to penetrate in the vertical direction, the support member 4 is arranged so that the fastening portion 8 protrudes upward from the through hole, and a nut is attached to the protruding portion of the fastening portion 8 for fixing. You may

The support member 4 preferably has a shape that allows the pipe hole of the column 12 to pass therethrough, has strength to withstand the maximum value of the load (permissible maximum load), and is capable of transmitting tension. Here, being able to transmit tension means that the elongation (deformation) of the support member 4 with respect to the tension applied to the support member 4 is within a certain standard.

For example, a weight is placed on the elevator car 100 to carry out a load load test, and this standard may be determined so that the deformation, movement amount, and inclination of the elevator car 100 fall within a certain range for specified load conditions. good. As described above, the material and shape of the support member 4 can be selected in consideration of the load weight, dead weight, dimensions, etc. of the elevator car 100 .

For example, as the support member 4, a rod that is bent into a predetermined shape in advance can be used. Next, the car floor 3 will be explained. As shown in the bottom view of FIG. 2, the car floor 3 has a rectangular shape in plan view. The shape of the car floor 3 is not limited to a quadrangle, but may be a polygon having three or more vertices in plan view, more preferably a convex polygon.

The car floor 3 is supported by the support member 4 at each vertex 24 . Even if the arrangement of the load on the car floor 3 changes, the position of the center of gravity of the load is inside the convex polygon with the vertex 24 as the vertex in a plan view. The bending moment acting on 12 can be reduced.

The car floor 3 may be provided with protrusions, recesses, holes, or the like. Also, the shape of the car floor 3 may be different from a polygon. For example, the corners of the vertices may be rounded with a corner radius or the like, and the line connecting the vertices may be different from a straight line.

Furthermore, the shape of the car floor 3 may be a shape different from the convex polygon. For example, the car floor 3 has a circular shape, an elliptical shape, or the like, and the vertex portions 24 are arranged on the surface of the car floor 3 such that the vertex portions 24 constitute the vertices of a convex polygon. More preferably, the apex 24 is located at the edge of the car floor 3 or at the edge, which is a portion close to the edge.

With such a structure, even if the arrangement of the load on the car floor 3 changes, the position of the center of gravity of the load can be placed inside the convex polygon with the vertex 24 as the vertex in plan view. It is possible to satisfy the conditions. A point inside the car floor 3 may be included in the peripheral edge portion where the vertex portion 24 is arranged within the range that satisfies the above conditions.

As shown in FIG. 2, if the shape of the car floor 3 is a convex polygon and the apex portion 24 is at the vertex of the car floor 3, most of the car floor 3 is convex with the apex portion 24 as the vertex. Inside the polygon. Therefore, the position of the center of gravity of the load can be more reliably placed inside the convex polygon having the vertex 24 as the vertex in a plan view, regardless of the arrangement of the load, which is further preferable.

Next, a fixed portion between the car floor 3 and the support member 4 will be described. FIG. 6 is an enlarged view of part of the elevator car 100 according to Embodiment 1 for carrying out the present invention. FIG. 6 is an enlarged view of part A in FIG. The vertex portion 24 is provided with a car floor through-hole 14 which is a hole penetrating the car floor 3 in the vertical direction.

In FIG. 6 , the column 12 is arranged such that the pipe hole of the column 12 is positioned vertically above the car floor through-hole 14 . The pillars 12 are perpendicular to the plane of the car floor 3 . In the following description, being perpendicular to the plane of the car floor 3 is called "perpendicular to the car floor 3". In FIG. 6, the column 12 is directly provided on the car floor 3, but it is sufficient if the lower end of the column 12 faces the upper surface of the car floor 3, and a vibration absorbing material or the like is interposed therebetween. may be placed.

The support member 4 extends through the pipe hole of the column 12 , the car floor through-hole 14 of the car floor 3 , and the support plate through-hole 15 of the support plate 10 . The maximum diameter of the fastening portion 8 is smaller than the minimum diameters of the car floor through hole 14 and the support plate through hole 15 . Here, the diameter means the diameter of the fastening portion 8, the car floor through-hole 14, and the support plate through-hole 15 in the xy plane of FIG.

A fastening member 9 is fastened to a fastening portion 8 of the support member 4 projecting to the lower surface side of the car floor 3 , and a support plate 10 is arranged between the fastening member 9 and the car floor 3 . A configuration without the support plate 10 is also possible. The force acting on the car floor 3 from the support member 4 acts on the car floor 3 from the lower surface side. The fastening member 9 in FIG. 6 is a nut.

The fastening member 9 is attached to the fastening portion 8 protruding downward from the lower surface of the car floor 3, applies force directly or indirectly to the car floor 3, and receives the weight of the elevator car 100 and its load. It is a member and is not limited to a nut. Also, the method of connecting the fastening portion 8 and the fastening member 9 is not limited to fastening with screws.

For example, the fastening member 9 may be a metal member that can be attached to the fastening portion 8, does not pass through the support plate through-hole 15, and has strength to withstand the weight that acts on it. The method of connecting the fastening portion 8 and the fastening member 9 may be, for example, screwing, welding, riveting, hooking, or a combination thereof.

In FIG. 6 , the maximum outer diameter of the fastening member 9 is larger than the minimum diameters of the car floor through-hole 14 and the support plate through-hole 15 . For example, the maximum diameter of the outer shape of the support plate 10 is made larger than the minimum diameter of the car floor through hole 14, the maximum diameter of the outer shape of the fastening member 9 is made larger than the minimum diameter of the support plate through hole 15, and the outer shape of the fastening member 9 is increased. The maximum diameter may be smaller than the minimum diameter of the car floor through hole 14 .

In this embodiment, the support member 4 penetrates the car floor through-hole 14 from the upper surface to the lower surface, and can support the car floor 3 from the lower surface. However, the form of fixing the car floor 3 and the support member 4 is not limited to this, and a form in which the support member 4 is fixed to the upper surface of the car floor 3 may be employed.

Since the support member 4 is guided by the column 12 from the upper end to the lower end of the column 12, there is no need to separately provide a member for guiding the support member 4. FIG. Therefore, the weight of the elevator car 100 can be reduced. Here, the method of fixing the support members 4 and the car floor 3 is not limited to the form shown in FIG.

For example, the support member 4 may pass through the car floor through-hole 14 from the upper surface to the lower surface, the support member 4 may be connected to the connection position on the lower surface of the car floor 3, and the connection position may be located away from the vertex 24. . The support member 4 is stretched from the car floor through-hole 14 to the connection position, and the support member 4 and the car floor 3 are in contact with each other at the apex 24. Even if the support member 4 supports the car floor 3 at this contact point. good.

Also, the support member 4 can be arranged as follows. One end of the support member 4 is fixed to the rope connecting part 1 and stretched from the rope connecting part 1 to the upper end of the pillar 12 (referred to as the first pillar 12-1). Further, the pipe hole of the first pillar 12-1 is shaped so as to penetrate from the upper end to the lower end, and the car floor through-hole 14 penetrates from the upper surface to the lower surface at the vertex portion 24 where the first pillar 12-1 is arranged. Let

Next, on the lower side of the car floor 3, the support member 4 is moved from the vertex 24 where the first pillar 12-1 is arranged to another pillar 12 (referred to as a second pillar 12-2). The car floor through-hole 14 extends from the lower surface to the upper surface at the vertex portion 24 where the second post 12-2 is located. Further, the support member 4 is passed through the pipe hole of the second column 12-2 from the lower end to the upper end.

Then, the other end of the support member 4 extending from the pipe hole of the second column 12-2 is fixed to the rope connecting member 1. As shown in FIG. In this way, it is also possible to adopt a structure in which two apex portions 24 of the car floor 3 are supported by one supporting member 4 whose both ends are fixed to the rope connecting parts 1 .

Next, the car wall 2 will be described with reference to FIGS. 2 to 5. FIG. FIG. 5 is a trihedral view showing the car wall 2 of the elevator car 100 according to Embodiment 1 for carrying out the present invention. The car walls 2 are arranged on the side and rear sides of the elevator car 100, and are not provided on the front side where the doors are arranged. The car walls 2 are arranged perpendicular to the car floor 3 .

The wall panel 11 has a rectangular shape and is arranged so that two sides are perpendicular to the car floor 3 . Two pillars 12 are joined to one surface of the wall panel 11 along two sides perpendicular to the car floor 3 . In other words, the two pillars 12 are joined to the edge of one side of the wall panel 11 in parallel with the two sides perpendicular to the car floor 3 .

The pillars 12 joined to the wall surface panel 11 are two of the pillars 12 provided at the respective apex portions 24 and arranged at adjacent apex portions 24 . Here, the adjacent vertex portions 24 are the vertex portions 24 that are adjacent to each other with one side of the convex polygon formed by the vertex portions 24 interposed therebetween.

As shown in FIG. 5, upper beams 6 and lower beams 7 are joined along upper and lower sides parallel to the car floor 3 to the surface of the wall panel 11 to which the pillars 12 are joined. .

In other words, the upper beam 6 and the lower beam 7 are joined to the edge of one side of the wall panel 11 in parallel with the upper side parallel to the car floor 3 and the lower side parallel to the car floor 3. ing. The column 12, upper beam 6 and lower beam 7 may be joined together for added strength.

The method of joining the wall panel 11 to the column 12, the upper beam 6 and the lower beam 7 can be selected from adhesion, welding, screwing, etc., depending on the material. In the cage wall 2 shown in FIG. 5, the pillars 12, the upper beams 6 and the lower beams 7 are joined along each side of the wall panel 11, so that the wall panel 11 is resistant to the force that bends each side of the wall panel 11. It has a structure with high strength and rigidity.

Two or more pillars 12 may be arranged at one vertex portion 24 like the vertex portion 24 on the back side in FIG. The wall panel 11 may be fastened to the car floor 3 to reinforce the lower portion of the wall panel 11 . A structure in which a member is newly provided to reinforce the upper portion or the lower portion of the wall panel 11 and the upper beam 6 or the lower beam 7 can be omitted.

Moreover, the space between the car wall 2 and the car floor 3 or between two adjacent car walls 2 may be fixed by adhesion, welding, screwing, or the like. Since the elevator car 100 of this embodiment supports the car floor 3 from below, the weight is increased by reinforcing the fastening structure between the car wall 2 and the car floor 3 or between two adjacent car walls 2. can be suppressed.

The form of the wall surface panel 11 is not limited to a rectangle, and may be any shape as long as two pillars 12 arranged perpendicular to the car floor 3 and arranged at adjacent vertex portions 24 are joined to one surface. good. In such a configuration, the upper beams 6 and lower beams 7 parallel to the car floor 3 may be joined to the surfaces of the wall panels 11 to which the columns 12 are joined.

In the structure shown in FIGS. 2 to 4, the shape of the wall panel 11 is rectangular, and the pillars 12 are joined along the sides of the wall panel 11, so that the two pillars 12 protrude from the wall panel 11 and do not interfere with each other. It can be joined to the edge portion of the wall panel 11 . Therefore, the strength and rigidity of the car wall 2 can be efficiently increased with a small number of members.

By joining the upper beams 6 and the lower beams 7 parallel to the car floor 3 to the wall panel 11, the amount of reinforcing members is suppressed and the car wall 2 is strengthened against the force acting on the car wall 2. can be reinforced. As described above, it is possible to effectively increase the strength of the elevator car 100 while suppressing the amount of reinforcing members, and to provide the elevator car 100 with high load-bearing performance and light weight.

A member that reinforces the car wall 2 may be joined to the wall panel 11 instead of the upper beam 6 and the lower beam 7 . For example, a rod-shaped reinforcing member may be added along the diagonal line of the wall panel 11 to the rectangular wall panel 11 . Alternatively, the car wall 2 may be reinforced by joining rod-like members to the two pillars 12 instead of joining the wall panel 11 .

Next, the shapes and materials of the pillars 12, the upper beams 6, the lower beams 7 and the wall panels 11 will be described in more detail. As in this embodiment, as the pillar 12, a rectangular pipe material having a rectangular outer shape and a rectangular cross section of the pipe hole may be used. The upper beam 6 and the lower beam 7 may be rod-shaped and may not have pipe holes.

In addition to the pillars 12 , the upper beams 6 and the lower beams 7 , rod-shaped reinforcing members may be joined to the wall panel 11 . As the upper beam 6, the lower beam 7, and the reinforcing member, a pipe material, an L-angle material, a C-shaped material, an I-shaped material, or the like can be used. The L-angle material, the C-shaped material and the I-shaped material are rods having cross-sectional shapes close to the L-shape, the C-shape and the I-shape, respectively.

Also, the outer shape of the pillar 12 in FIG. 4 or the cross-sectional shape of the pipe hole may be circular, triangular, elliptical, polygonal, or the like. The column 12 may be provided with protrusions, recesses, through holes, joint surfaces, etc. for reinforcement, joining with other members, weight reduction, and the like. Also, the thickness and shape of the cross section may vary depending on the position in the longitudinal direction.

The pillar 12 in FIG. 4 has a pipe hole extending through the inside of the pillar 12 over the entire lengthwise direction. , grooves. In order to prevent the support member 4 from slipping out of the groove, the column 12 having the groove may be provided with a structure in which a pipe hole penetrates inside, a fastener, or the like.

In this case, two fasteners may be provided at the upper end and the lower end of the column 12 . Further, the car floor through hole 14 may function as a fastener. A structure in which a pipe hole extends through the entire lengthwise direction has strength that does not depend on the direction in a plane orthogonal to the pillar 12 compared to a structure in which a groove is partially formed in the lengthwise direction.

Further, in the column 12 of FIG. 4, since the pipe hole is positioned at the central portion of the cross section of the column 12, a lightweight structure with high strength and no anisotropy in strength can be realized. Furthermore, if the column 12 is integrally molded, the structure can be made high in strength and easy to manufacture. In particular, when fiber-reinforced plastic is used as the material, the structure can have high strength and can be easily manufactured.

The upper front beam 21, the lower front beam 22 and the pillars 12 may be joined together for increased strength. Also, the structure of the front component 19 is not limited to the structures shown in FIGS.

In this embodiment, a part such as a door (not shown) may be provided on the front side. If parts such as doors replace the functions of the front part 19, such as increasing the strength and rigidity of the elevator car 100, some or all of the parts of the front part 19 can be omitted.

Next, the upper end portion of the pillar 12 will be described. FIG. 7 is an enlarged view of part of the elevator car 100 according to Embodiment 1 for carrying out the present invention. FIG. 7 is an enlarged view of the B portion of FIG. 4, showing a plan view and a side view. A support member restraining component 13 is provided at the upper end of the column 12 .

The supporting member restraining part 13 has an external shape that can be fitted into a pipe hole at the upper end of the pillar 12, and is fixed to the pillar 12 by adhesion, screwing, or the like. The support member restraint component 13 may be fitted over the profile of the post 12 . The support member constraining component 13 is provided with a through hole through which the support member 4 penetrates.

Therefore, by mounting the support member restraint component 13, the movable range of the support member 4 in the horizontal direction (the direction within the xy plane) at the upper end of the column 12 is reduced, and the elevator car 100 is reduced in vibration. As the support member restraint component 13, a solid component molded in consideration of the cross-sectional dimensions of the support member 4 can be used.

When viewed from the direction perpendicular to the car floor 3, that is, when viewed from above, the support member fixing position 25, which is the position where the support member 4 is fixed to the rope connection component 1, is outside the convex polygon formed by the vertices 24. possible, but preferably inside.

In other words, it is desirable that a perpendicular line drawn from the support member fixing position 25 to the plane including the car floor 3 intersects the convex polygon formed by the vertex 24 . When the support member fixing position 25 is inside the convex polygon formed by the vertex 24 in plan view, the tension generated in the support member 4 by the weight of the elevator car 100 and the load is applied to the column 12 by the vertex 24 acts on the inside of the convex polygon whose vertex is .

Therefore, a force acts between the plurality of car walls 2 in the direction of pressing them against each other. Further, the force due to the weight of the elevator car 100 and the weight of the load acts in the direction of binding the plurality of car walls 2 together. With such a structure, it is possible to reduce the reinforcement of the fastening portion between the car walls 2, and the weight of the elevator car 100 can be reduced.

For comparison, a structure in which the support member fixing position 25 is outside the convex polygon formed by the vertices 24 in plan view will be described. In this structure, the tension generated in the support members 4 acts in the direction of pulling the car walls 2 away from each other, and the weight due to the reinforcement of the fastening portion between the car walls 2 is increased as compared with the above-described case.

Further, the elevator car 100 shown in FIGS. 2 to 4 has one end of the support member 4 extending from the inside of the pipe hole to the outside on the upper end side of the column 12 fixed, and suspended above the upper end of the column 12 by the main rope 5 . It has a lowered rope connection piece 1 .

Further, the elevator car 100 shown in FIGS. 2 to 4 is provided with one supporting member 4 corresponding to each of the vertex portions 24 . The support member 4 supports the corresponding vertex 24 , and the other end of the support member 4 extending from the inside of the pipe hole to the outside on the lower end side of the column 12 is fixed to the car floor 3 .

Further, in the elevator car 100 shown in FIGS. 2 to 4, the car floor 3 has a convex polygonal shape in a plan view, and the vertex portions 24 are positioned at the respective vertices of the car floor 3 .

Further, in the elevator car 100 shown in FIGS. 2 to 4 , the wall panel 11 has a rectangular shape with two sides perpendicular to the car floor 3 . Two pillars 12 respectively arranged at adjacent vertex portions 24 are joined along two sides of one surface of the wall panel 11 .

Further, the elevator car 100 shown in FIGS. 2 to 4 further includes rod-shaped upper beams 6 and lower beams 7 . The upper beam 6 is joined along the upper side parallel to the car floor 3 on one side of the wall panel 11 , and the lower beam 7 is joined along the lower side parallel to the car floor 3 on one side of the wall panel 11 . Joined along the edges.

Further, in the elevator car 100 shown in FIGS. 2 to 4, in a plan view seen from a direction perpendicular to the car floor 3, the support member fixing position 25, which is the fixing position between the rope connection component 1 and the support member 4, is , the vertex portion 24 is inside the convex polygon forming the vertex.

Further, in the elevator car 100 shown in FIGS. 2 to 4, a car floor through hole 14 extending from the upper surface to the lower surface of the car floor 3 is provided vertically below the pipe hole of the column 12 . The supporting member 4 passes through the car floor through-hole 14 , and the fastening member 9 is attached to the portion of the supporting member 4 that protrudes toward the lower surface of the car floor 3 .

In such an elevator car 100 , the car floor 3 can be supported from below by the support members 4 and the fastening members 9 . Further, the fixing of the car floor 3 and the support member 4 can be made stronger. Furthermore, the fixing work of the car floor 3 and the support member 4 can be facilitated, and the installation work of the elevator car 100 in the hoistway 202 can be facilitated.

In the elevator car 100 of this embodiment, the load and the self weight of the elevator car 100 are distributed between the support members 4, and the load on the joints between the support members 4 and the car floor 3 is reduced. Furthermore, since the car floor 3 is supported by the support members 4 , no load acts on the joints between the components of the elevator car 100 except between the car floor 3 and the support members 4 .

Furthermore, since the center of gravity of the load of the elevator car 100 is located inside the convex polygon formed by the vertex 24 in plan view, the bending moment applied to the column 12 is reduced. Furthermore, since the support member 4 can be guided by the column 12, there is no need to separately provide a guide member and a member for supporting the guide member.

As described above, according to the embodiment of the present invention, it is possible to suppress an increase in weight due to reinforcement for withstanding self weight, load, and bending moment, compared with a conventional elevator car. It is possible to provide the elevator car 100 with high load capacity and light weight.

Next, with reference to FIG. 8, an example of the orientation direction of the fibers when the material of the parts constituting the car wall 2 is FRP will be described. FIG. 8 is a front view and a side view showing orientation directions of fibers of the car wall 2 of the elevator car 100 according to Embodiment 1 for carrying out the present invention. 8(a) is a front view of the car wall 2, and FIG. 8(b) is a side view of the car wall 2. FIG. The direction of fiber orientation is indicated by arrows.

Coordinate axes are shown in FIG. The cage walls 2 are shown parallel to the xz plane. The column 12 is shown parallel to the z-axis, and the upper beam 6 and lower beam 7 are shown parallel to the x-axis. A panel material made of FRP is used for the wall panel 11 . As shown in FIG. 8(a), the wall panel 11 is a multiaxial laminate having four orientation directions.

The four directions are the vertical axis direction (z-axis direction), the horizontal axis direction (x-axis direction), the first oblique direction, and the second oblique direction. The first oblique direction and the second oblique direction are parallel to the xz plane, and are inclined at an inclination angle θ with respect to the vertical axis direction. The inclination angle θ is an angle smaller than 90 degrees and larger than 0 degrees, preferably in the range of 30 degrees to 60 degrees. It is more preferable to set the inclination angle θ to 45 degrees.

By configuring the orientation direction of the panel material in this way, it is possible to obtain a panel material whose strength and stiffness do not greatly depend on the direction in which the force acts.

Furthermore, for example, 2n layers (where n is an integer of 1 or more) are provided for each portion configured in a single orientation direction, so that the entire panel material has a laminated structure of a total of 8n layers. Then, a plane of symmetry parallel to the plane of the panel material (the xz plane in FIG. 8A) can be provided, and the panel material can be constructed so that the laminated structure is symmetrical about this plane of symmetry.

With such a laminated structure, it is possible to obtain the wall panel 11 with a small amount of deformation (warp) caused by the difference between the characteristics in the z-axis direction and the characteristics in the x-axis direction. Here, the characteristics are expansion rate, rigidity, and the like.

Here, FIG. 8 shows the wall panel 11 composed only of FRP, but for example, a composite material in which FRP is combined with metal, ceramics, resin, or the like may be used. Next, it is desirable that the column 12, the upper beam 6 and the lower beam 7 have high strength and rigidity against forces acting in the longitudinal direction.

As shown in FIGS. 8(a) and 8(b), the upper beam 6, the lower beam 7, and the column 12 can be made of a unidirectional material whose fibers are oriented in the axial direction of the pipe. Here, the axial direction of the pipe is the direction parallel to the through-hole direction of the pipe hole of the pillar 12 and is the longitudinal direction. The unidirectional pipe material used for the pillars 12 and the like may be manufactured by a pultrusion method.

Also, the upper beam 6, the lower beam 7, and the column 12 may be made of FRP with fibers oriented in the axial direction of the pipe, and composite materials such as metal, ceramics, and resin. The pultrusion method is a manufacturing method suitable for molding long members having the same cross section in which fibers are oriented in the longitudinal direction, and can efficiently manufacture long members having the same cross section.

By combining the wall panel 11 formed of the panel material having the fiber orientation direction as described above and the upper beam 6, the lower beam 7 and the column 12 formed of pipe material, the force in the x-axis direction and the force in the z-axis direction It is possible to obtain a car wall 2 having similar characteristics such as strength and rigidity against both forces. Moreover, the car wall 2 with high load-bearing performance can be obtained.

As described above, the column 12 shown in FIG. 8 contains fiber-reinforced plastic, and the orientation direction of the fibers of the fiber-reinforced plastic contained in the column 12 is parallel to the longitudinal direction of the column 12 . Further, the wall panel 11 of the elevator car 100 using the car wall 2 shown in FIG. Furthermore, the upper beam and the lower beam contain fiber reinforced plastic, and the orientation direction of the fibers of the fiber reinforced plastic contained in the upper beam and the lower beam is parallel to the longitudinal direction of the upper beam and the lower beam.

Furthermore, the orientation directions of the fibers are composed of the following four directions. The four directions are the vertical direction that is perpendicular to the car floor 3, the horizontal direction that is parallel to the car floor 3, and the first oblique direction that is tilted at an angle of 90 degrees or less with respect to the vertical direction. It is a second oblique direction that is opposite to the first oblique direction by an oblique angle with respect to the direction and the longitudinal direction.

In the elevator car 100 of this embodiment, the apexes 24 serving as support points are provided at three or more locations on the car floor 3 in plan view, and the load and the weight of the elevator car 100 are 3 or more. 4 are distributed. Therefore, an increase in weight due to reinforcement of the support member 4 and the connecting portion between the support member 4 and the car floor 3 can be suppressed.

Further, since the car floor 3 in the lower part of the elevator car 100 is supported by the support member 4, it is possible to reduce the portion where the load acts, that is, the portion that needs to be reinforced to withstand the load, among the fastening portions between the members. .

In addition, since the car floor 3 is supported by the vertex portions 24 forming the vertices of the convex polygon on the car floor 3, the center of gravity of the load can be maintained within the convex polygon having the vertex portions 24 as vertices. and the bending moment caused by eccentric loads is reduced. Therefore, an increase in weight due to reinforcement of the column 12 can be suppressed.

Also according to this embodiment, the support member 4 is guided by the post 12 . Therefore, it is not necessary to separately provide a guide member for the support member 4, and it is possible to provide the elevator car 100 having high load-bearing performance and light weight.

In addition, when the support member fixing position 25 is provided inside the convex polygon formed by the vertex portion 24 in a plan view, a force acts in the direction in which the car walls 2 are pressed against each other, and the fastening portion between the car walls 2 is applied. It is possible to suppress the increase in weight due to the reinforcement of the

An elevator car 100c according to Embodiment 4 for carrying out further includes a car ceiling 300 above the car wall 2 in addition to the configuration of the elevator car 100 according to Embodiment 1 for carrying out. 13A and 13B are a front view and a top view of an elevator car 100c according to Embodiment 4 for carrying out the present invention. 14A and 14B are a front view and a top view of a car ceiling 300 according to a fourth embodiment of the present invention. FIG. 15 is an enlarged view of a part of the car ceiling 300. As shown in FIG. That is, FIG. 15 is an enlarged perspective view of the E portion, which is the vertex portion of the car ceiling 300 in FIG. 14 . A car ceiling 300 according to Embodiment 4 is composed of a first ceiling panel 301 and ceiling beams 302 .

The first ceiling panel 301 has the same convex polygon shape as the car floor 3 . The ceiling beams 302 are arranged along each side of the convex polygon forming the first ceiling panel 301 and joined to the upper surface of the first ceiling panel 301 . As the ceiling beam 302, a pipe material, an L-angle material, a C-shaped material, an I-shaped material, or the like can be used.

In FIGS. 14 and 15, the first ceiling panel 301 has a shape with rounded corners. This allows the support member 4 to pass through the car ceiling 300 . The apex of the first ceiling panel 301 does not necessarily have to be rounded, and for example, a hole large enough for the support member 4 to pass through may be made.

The materials of the first ceiling panel 301 and the ceiling beams 302 are not particularly limited as long as they can withstand the load (for example, the weight of an installation worker) acting directly on the upper surface of the first ceiling panel 301 . The material of the first ceiling panel 301 may be metal such as iron or aluminum. FRP reinforced with fibers such as carbon fibers and glass fibers may also be used. A composite material containing metal, carbon fiber and glass fiber may also be used. From the viewpoint of weight reduction, FRP is particularly suitable as the material for the first ceiling panel 301 and the ceiling beams 302 . When the material of the first ceiling panel 301 and the ceiling beam 302 is FRP, the fiber orientation direction is parallel to the first ceiling panel, and the material properties of the first ceiling panel are the same as those of the first ceiling panel. It is isotropic with respect to the in-plane direction of the ceiling panel. When the material of the ceiling beams 302 is FRP, the orientation direction of the fibers of the FRP contained in the ceiling beams 302 is parallel to the longitudinal direction of the ceiling beams 302 . Furthermore, the car ceiling 300 is integrally fastened with the upper beam 6 . The fastening method is, for example, bolt-nut fastening, but is not particularly limited.

In the case of the structure of the elevator car 100 according to Embodiment 1 for implementation, a compressive load acts on the upper beam 6 via the support member 4 . As the load increases, the compressive load also increases proportionally, increasing the risk of buckling failure of the upper beam 6 .

A first method for preventing the buckling failure of the upper beam 6 is to increase the thickness of the upper beam 6 itself. However, since the upper limit of the dimension of the upper beam 6 is determined in relation to other members and the dimension of the hoistway, the dimension cannot be determined based only on buckling failure. In addition, there is a problem that increasing the thickness of the upper beam 6 increases the weight and reduces the weight reduction effect.

In the elevator car 100c according to Embodiment 4 for implementation, the car ceiling 300 and the upper beam 6 are integrally fastened. With such a configuration, the car ceiling 300 functions as a gusset for the upper beam 6, and the buckling failure of the upper beam 6 can be prevented.
