CONSTITUTION:A lower metal plate 31a having an area as same as a cage floor frame 20 is placed on the cage floor frame 20, and a honeycomb plate 22 having an area as same as the inside area of a cage chamber is placed on the lower metal plate 31a for bonding. A rectangular frame fixing member 32 is fitted so as to surround the periphery of the honeycomb plate 22 to prevent deformation of the honeycomb plate 22. An upper metal plate 31b is placed on the honeycomb plate 22 and the fixing member 32 for bonding so as to cover them, and a plywood 23 and a glazed tile 24 are bonded. The floor plate 20 and the skirting board 25 are bonded to the fixing member 32 with bolts. Consequently, deflection to be caused by offset of a load is absorbed with the tensile force of the metal plates 31a, 31b to maintain the rigidity.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an elevator car, and particularly to an elevator car using a honeycomb plate for the car floor.

(Prior Art) Generally, as shown in FIG.
An elevator car 14 and a counterweight 15 are attached to both ends of a wire robe 13 hung on the hoist 12, and these are suspended so as to maintain balance.

The elevator car 14 is composed of a car floor 16, a car chamber 17, and a car frame 18 that strongly supports the car floor 16, and is guided by a guide rail 19 installed vertically over the entire length of the elevator passage 10. It seems to be going up and down while being lifted.

Therefore, by reducing the weight of the elevator car 14, the weight of the counterweight 15 can be reduced, and the load on the hoisting machine 12 is reduced.
Energy saving will be achieved. At the same time, this makes it possible to reduce the load on the building structure, thereby reducing construction costs, equipment costs, etc.

For this reason, honeycomb plates are used in elevator cars, especially in the car floor, to reduce the weight of the car floor.

The cage floor 16 using this honeycomb board has a structure as shown in FIGS. 4, 5, and 6. That is, the elevator car 14 is composed of a car floor 16, a car chamber 17, and a car frame 18, and the floor area of the car floor 16 is made equal to the internal area of the car chamber 17.

This car floor 16 is composed of a floor frame 20 and a floor member attached to the upper part of this floor frame 20.
is a rectangular frame made of steel material with a U-shaped cross section fixed by welding or the like. In addition, the floor member includes a metal plate 21 having a size that extends to the end of the floor frame 20 and has a thickness of about 0.5 to 1.6 mm, and has a 71 plate having a size slightly smaller than the internal area of the car compartment 17 on the top surface of the metal plate 21.
A honeycomb board 22 is placed on top of the honeycomb board 22, and a decorative tile 24 is placed on top of the honeycomb board 22 with a plywood board 23 interposed therebetween, and these are adhesively bonded in a sandwich-like manner using an epoxy-based adhesive, a chloroprene-based adhesive, or the like.

The honeycomb plate 22 is generally a porous flat plate made by laminating and bonding cylindrical bodies of light metal plates or fiber reinforced plastic plates (FRP), and is lightweight and has high rigidity in the thickness direction. It's big. Therefore, it is often used in lightweight structures.

A square baseboard 25 made of steel is attached to the upper surface of the metal plate 21 of this floor member except for the entrance part, and a car compartment side plate 26 forming the car compartment 17 is attached to this baseboard 25. In addition, a threshold 27 is attached to the entrance of the metal plate 21,
An elevator door 28 is provided so that it can be opened and closed freely, and
A ceiling plate 29 is attached to the upper part of this car side plate 26.

A steel car frame 18 is provided below the car floor 16 to support the elevator car 14 via vibration-proof rubber 30, 30.

(Problem to be solved by the invention) In an elevator car having such a configuration, the number of passengers and their riding positions are not constant, so the load is concentrated in the center of the car floor or concentrated in one corner. Sometimes.

This variation in load causes the car floor to bend (see Figure i7). In particular, since elevator cars are used for long periods of time, the floor of the car repeatedly bends as passengers get on and off the car, deforming the honeycomb plate and causing the bond between it and the metal plate to separate. Therefore, there is a problem that the rigidity of the car floor is reduced and its function is impaired.

In order to solve the above-mentioned problem, the present invention provides an elevator car in which the rigidity of the car floor does not decrease even if the car floor undergoes repeated load fluctuations.

[Structure of the invention]

(Means for Solving the Problem) The present invention has a honeycomb plate bonded between upper and lower metal plates in a sandwich-like manner, and a frame-shaped frame surrounding the outer periphery of the honeycomb plate is provided on the outer periphery between the upper and lower metal plates. A fixing member is interposed and bonded to form a car floor, and the upper and lower metal plates are fixed together with the fixing member to the floor frame and baseboard.

(Function) When passengers ride on the elevator car floor in a concentrated manner or in the corners, the elevator car floor tends to flex.
This deflection is absorbed by the tensile force of the upper and lower metal plates sandwiching the honeycomb plate, reducing the deflection of the elevator car floor.

Therefore, the peeling phenomenon of the honeycomb plate is eliminated, and its rigidity is not impaired, so that the function of the elevator car is maintained.

(Example) An example of the elevator car of the present invention will be described below with reference to the drawings.

In the drawings, the same parts as in FIGS. 3, 4, 5, 6, and 7 are designated by the same reference numerals, and detailed explanation thereof will be omitted.

1 and 2 show an elevator car 14. FIG. A floor frame 20 is attached to the car floor 16 of the elevator car 14, and a lower metal plate 31a having the size of the floor frame 20 is placed on top of the floor frame 20. This metal plate 31
A /X nicomb board 22, which is about the same size as the internal area of the car compartment side plate 26, is also mounted and adhered to the upper part of a. A fixing member 32 having a rectangular frame is attached so as to surround the outer periphery of the /1 honeycomb plate 22 and the honeycomb plate 22 to prevent the honeycomb plate 22 from deforming.

An upper metal plate 31b is mounted and adhered to the upper part of the honeycomb plate 22 and the fixing member 32 so as to cover them, and the plywood 23 and the decorative tile 24 are placed on the upper part of the metal plate 31b.
etc. are attached, and these are joined with adhesive so that they form a sandwich.

In this way, the lower metal plate 31a and the lower part of the fixing member 32 are fixed by the bolts 33 and nuts 34, the upper metal plate 31b and the upper part of the fixing member 32 are fixed by the bolts 33 and nuts 34, and the floor frame 20 and baseboard 25 are combined.

In this way, even if a large number of passengers repeatedly get on and off the elevator car 14 and the load is concentrated in the center of the car 14 or applied to the corners, the metal parts on the top and bottom of the car floor 16 can be removed. Tensile force acts on the plates 31a and 31b, and deflection due to the load is absorbed.

Therefore, the deformation of the honeycomb plate 22 is prevented, the peeling phenomenon between the honeycomb plate 22 and the metal plates 31a and 31b is eliminated, the rigidity of the elevator car 14 is not impaired, and its function can be maintained for a long time.

〔Effect of the invention〕

In the elevator car of the present invention, a honeycomb plate is bonded between upper and lower metal plates in a sandwich manner, and a frame-shaped fixing member surrounding the outer periphery between the upper and lower metal plates is interposed and bonded to form the car floor. Since the upper and lower metal plates are fixed to the floor frame and baseboard together with the fixing members, this elevator car can be made light and highly rigid.

Furthermore, even if the car floor is subjected to a bending load, the peeling phenomenon between the upper and lower metal plates and the Nicum plate is prevented, and its high rigidity can be stably maintained for a long time.
