Detailed Description
In the method for assembling an elevator car and a car platform according to the present invention, the work of coupling the slab to the floor can be performed by one person, and the number of members for fixing the slab to the floor can be reduced, thereby reducing the cost required for the assembly work of the platform (car platform). In the method of assembling the car and the car bottom of the elevator according to the present invention, the slab can be accurately arranged and fixed to the floor in a short time, and therefore, the effect of improving the workability of assembling the car bottom can be obtained.
Hereinafter, an assembly method of a car and a car bottom of an elevator according to an embodiment of the present invention will be described with reference to the drawings.
Fig. 7 is a diagram showing the car 10 of the elevator of the present embodiment. In fig. 7, the interior of the car 10 is shown. The car 10 includes: a car floor 1 on which passengers and cargo are placed; a side plate 8 erected on the car bottom 1; a top plate 9 covering the upper part of the side plate 8; and a car door 11 that is provided on the side plate 8 and opens and closes.
Fig. 1 is a structural diagram showing a car floor 1 of a car 10 of an elevator according to the present embodiment. The car bottom 1 includes a bottom plate 2, a plurality of slabs 3, and a skirting board 4. The floor panel 2 has an upper surface on which passengers and cargo are placed, and a slab 3 is fixed to a lower surface (a bonding surface 2a) on the opposite side of the upper surface. The plurality of slabs 3 are members for reinforcing the bottom plate 2, and are arranged parallel to each other along the bonding surface 2a of the bottom plate 2. Skirting boards 4 are provided on the periphery of the upper surface of the base plate 2.
The base plate 2 has a plurality of positioning holes 5 at one end. The positioning holes 5 preferably penetrate the bottom plate 2 and are provided only in the same number as the number of slabs 3 (for example, six in fig. 1). The positioning hole 5 is preferably formed in one end portion of the bottom plate 2 by punching (punching) in the manufacturing of the bottom plate 2.
The blank 3 has a positioning protrusion 6 at one end.
Fig. 8 is a view showing the slab 3. The blank 3 is formed of a metal plate-like member (for example, a steel plate) and has a shape of substantially コ, and includes a bonding surface 3a which is a surface contacting the bonding surface 2a of the bottom plate 2 and two surfaces intersecting the bonding surface 3a substantially perpendicularly. The blank 3 includes a positioning projection 6 at one end of the bonding surface 3 a.
The positioning projection 6 extends from the joint surface 3a, and before the blank 3 is fixed to the bottom plate 2, the positioning projection 6 projects in parallel with the joint surface 3a, and after the blank 3 is fixed to the bottom plate 2, the positioning projection 6 engages with the positioning hole 5 of the bottom plate 2 in a bent state. The positioning projection 6 has a size that can be inserted into the positioning hole 5 of the bottom plate 2, and the positioning projection 6 is provided at a position that is positioned inside the positioning hole 5 and engages with the positioning hole 5 when the slab 3 is fixed to the bottom plate 2.
The positioning projection 6 includes a bent portion 6b serving as a connecting portion with the bonding surface 3a of the slab 3. The bent portion 6b protrudes in parallel with the joining surface 3a before the blank 3 is fixed to the bottom plate 2, and after the blank 3 is fixed to the bottom plate 2, the bent portion 6b is plastically deformed and bent at a substantially right angle from the positioning hole 5. After the blank 3 is fixed to the bottom plate 2, the portion of the positioning projection 6 located at the front end of the bent portion 6b is located inside the positioning hole 5. A part of the portion at the front end of the bent portion 6b may protrude from the bottom plate 2. The portion of the positioning protrusion 6 that is located at the front end of the bent portion 6b and protrudes from the bottom plate 2 is referred to as a front end portion 6 a. The positioning projection 6 is engaged with the positioning hole 5 in this manner.
The positioning projection 6 is made of a plastic material made of metal and made of the same material (for example, steel plate) as the slab 3. The positioning projection 6 has a strength enough to be plastically deformed and bent by the force of the operator. The positioning projection 6 is preferably formed at one end of the blank 3 by punching at the time of manufacturing the blank 3. If the positioning projections 6 are formed by punching, additional members for constituting the positioning projections 6 are not required, the number of members for fixing the blank 3 to the bottom plate 2 can be reduced, and the cost required for the assembly work of the car bottom 1 can be reduced.
The shapes of the positioning hole 5 and the positioning protrusion 6 can be set arbitrarily. An example of a preferable shape of the positioning hole 5 and the positioning protrusion 6 will be described below.
Fig. 9 is a diagram showing an example of a preferable shape of the positioning hole 5 and the positioning projection 6, and shows a part of the bottom plate 2 and the slab 3. Fig. 10 is an enlarged view of a portion shown in a of fig. 9. The positioning hole 5 is preferably trapezoidal in shape having two portions having different widths (i.e., a wide portion 5a and a narrow portion 5b having a smaller width than the wide portion 5 a). The positioning projection 6 is preferably shaped such that the width of the distal end portion 6a is larger than the width of the bent portion 6 b. The width of the tip portion 6a is smaller than the width of the wide portion 5a and larger than the width of the narrow portion 5 b. The width of the bent portion 6b is smaller than the width of the narrow portion 5 b.
When the positioning hole 5 and the positioning protrusion 6 have the shapes shown in fig. 9 and 10, the following effects can be obtained.
In the method of assembling the car bottom 1 of the car 10 according to the embodiment of the present invention, as will be described later, the worker inserts the positioning projections 6 into the positioning holes 5 and brings the entire bonding surface 3a of the blank 3 into contact with the bonding surface 2a of the floor panel 2. In this step, the operator inserts the positioning projection 6 into the positioning hole 5 by moving the slab 3 as indicated by arrow B in fig. 10. At this time, the positioning projection 6 is inserted into the wide portion 5a of the positioning hole 5. In the positioning projection 6, a tip end portion 6a protrudes downward from the bottom plate 2, and the other portion is positioned inside the positioning hole 5. Before bringing the bonding surface 3a of the slab 3 into contact with the bonding surface 2a of the bottom plate 2, the operator moves the slab 3 as indicated by an arrow C in fig. 10, and moves the positioning projection 6 toward the narrow portion 5b of the positioning hole 5. Since the width of the distal end portion 6a is larger than the width of the narrow portion 5b, the positioning projection 6 cannot be pulled out from the positioning hole 5. Thus, the operator can accurately specify the position of the slab 3 with respect to the floor panel 2, and can prevent the positioning projection 6 from being pulled out of the positioning hole 5.
Thereafter, the operator presses the blank 3 against the bottom plate 2, and brings the entire bonding surface 3a of the blank 3 into contact with the bonding surface 2a of the bottom plate 2. The bent portion 6b is plastically deformed and bent at a substantially right angle, thereby engaging the positioning projection 6 with the positioning hole 5.
In the car bottom 1 of the car 10 of the present embodiment, since the bottom plate 2 is provided with the positioning holes 5 and the slab 3 is provided with the positioning projections 6, the slab 3 can be accurately fixed to the bottom plate 2 in a short time, and the workability of assembling the car bottom 1 can be improved.
As shown in fig. 1, the bottom plate 2 and the blank 3 have coupling holes 12 at the other end portions. The joining hole 12 of the bottom plate 2 and the joining hole 12 of the slab 3 are provided at positions facing each other when the slab 3 is fixed to the bottom plate 2. The coupling hole 12 is preferably formed by punching in the manufacturing of the bottom plate 2 and the blank 3.
The fixing member 7 is inserted into the coupling hole 12 to fix the other end portion of the bottom plate 2 and the other end portion of the slab 3 to each other. The fixing member 7 is a mechanical coupling member, and for example, a rivet member such as a rivet, a bolt, and a screw may be used.
In the car bottom 1 of the car 10 of the present embodiment, the bottom plate 2 and the slab 3 are coupled to each other using the positioning projections 6, the adhesive, and the fixing members 7. The positioning projection 6 is inserted into the positioning hole 5 and engaged with the positioning hole 5, thereby fixing the one end portion of the bottom plate 2 and the one end portion of the slab 3 to each other. The adhesive is applied to the bonding surface 2a of the base plate 2, thereby fixing the bonding surface 2a of the base plate 2 and the bonding surface 3a of the blank 3 to each other. The fixing member 7 is inserted into the coupling hole 12 of the bottom plate 2 and the slab 3, thereby fixing the other end portion of the bottom plate 2 and the other end portion of the slab 3 to each other.
Next, a method of assembling the car bottom 1 of the car 10 according to an embodiment of the present invention will be described with reference to fig. 2 to 6. Fig. 2 is a diagram illustrating a first step of the method of assembling the car bottom 1 of the car 10 according to the present embodiment. Fig. 3 is a diagram showing a second step that is a step after the first step. Fig. 4 is a diagram showing a third step that is a step after the second step. Fig. 5 is a diagram showing a fourth step that is a step after the third step. Fig. 6 is a diagram showing a fifth step that is a step after the fourth step. The work of joining the floor panel 2 and the slab 3 in the first to fifth steps can be basically performed by one operator.
As shown in fig. 2, when assembling the car bottom 1, the worker performs the following first step. The worker sets the base plate 2 so that the joint surface 2a (i.e., the lower surface) of the base plate 2 faces upward. Then, an adhesive is applied to the bonding surface 2a of the base plate 2. The adhesive is applied to the portion of the bonding surface 2a that contacts the blank 3. Then, the operator lifts the slab 3 to be placed on the bonding surface 2a of the bottom plate 2 so as to stand vertically with respect to the bottom plate 2, and vertically faces the positioning holes 5 of the bottom plate 2 and the positioning projections 6 of the slab 3.
Next, as shown in fig. 3, the worker performs the following second step. That is, the operator lowers the raised slab 3 and inserts the positioning projections 6 into the positioning holes 5 in a state where the slab 3 is standing upright with respect to the floor panel 2. After the second step, the positioning projection 6 is positioned inside the positioning hole 5. A part (tip end portion 6a) of the positioning projection 6 may protrude from the base plate 2. In this way, the operator determines the position of the slab 3 with respect to the floor panel 2.
Next, as shown in fig. 4, the worker performs the following third step in a state where the positioning projection 6 is positioned inside the positioning hole 5. That is, the operator sets the blank 3 so that the joining surface 3a of the blank 3 faces the joining surface 2a of the bottom plate 2 with the positioning projection 6 inserted into the positioning hole 5. At this time, the bent portion 6b of the positioning projection 6 is plastically deformed and bent. The operator pushes down the blank 3 so as to apply its own weight, for example, and plastically deforms the bent portion 6b of the positioning projection 6 so that the joining surface 3a of the blank 3 faces the joining surface 2a of the bottom plate 2.
Next, as shown in fig. 5, the worker performs the following fourth step. That is, the operator brings the entire bonding surface 3a of the slab 3 into contact with the bonding surface 2a of the bottom plate 2. For example, the operator pushes the blank 3 down by substantially 90 degrees, and presses the blank 3 against the bottom plate 2 by bringing the entire bonding surface 3a of the blank 3 into contact with the bonding surface 2a of the bottom plate 2. The positioning projection 6 engages with the positioning hole 5 in a state where the bent portion 6b is plastically deformed and bent at a substantially right angle and a portion of the bent portion 6b at the tip thereof is positioned inside the positioning hole 5. (the tip end portion 6a of the positioning projection 6 may protrude from the bottom plate 2.) in the fourth step, the positioning projection 6 is engaged with the positioning hole 5 to join the bottom plate 2 and the one end portion of the slab 3 to each other, and the joint surface 3a of the slab 3 and the joint surface 2a of the bottom plate 2 are bonded to each other with an adhesive to fix the slab 3 to the bottom plate 2.
The operator repeats the operations of the first to fourth steps (fig. 2 to 5) the number of times corresponding to the number of slabs 3. The above-described work can be performed by one operator.
Next, as shown in fig. 6, the worker performs the following fifth step. First, the operator sets the bottom plate 2 to which the slab 3 is fixed such that the bonding surface 2a faces downward. That is, the operator turns the floor panel 2 upside down so that the slab 3 is positioned below the floor panel 2. This operation may be performed by a plurality of operators. Subsequently, the operator inserts the fixing member 7 into the coupling hole 12 of the bottom plate 2 and the slab 3, and fixes the other end portion of the bottom plate 2 and the other end portion of the slab 3 to each other using the fixing member 7. This operation can be performed by one operator. In the fifth step, the slab 3 is fixed to the floor panel 2 by joining the floor panel 2 and the other end portion of the slab 3 to each other using the fixing member 7.
The bottom plate 2 may have a reduced design due to the positioning projection 6 provided at one end and the fixing member 7 provided at the other end. That is, the front end portion 6a of the positioning projection 6 protrudes from the floor panel 2, or the fixing member 7 is visible to the passengers of the elevator, so that there is a concern that the design of the car bottom 1 is deteriorated.
In the car 10 of the elevator of the present embodiment, the skirting board 4 provided on the peripheral edge of the bottom plate 2 preferably covers the positioning hole 5, the positioning protrusion 6 protruding from the positioning hole 5, the coupling hole 12 of the bottom plate 2, and the fixing member 7 (see fig. 1) inside the coupling hole 12 of the bottom plate 2. The positioning projection 6 and the fixing member 7 can be made invisible to the passenger by the skirting board 4, and the design of the car platform 1 can be prevented from being deteriorated.
As described above, in the car 10 of the elevator of the present embodiment, the bottom plate 2 of the car bottom 1 and the slab 3 are coupled to each other at one end portion by the positioning projection 6 engaging with the positioning hole 5 in a state of being bent by plastic deformation. The bottom plate 2 and the slab 3 are fixed to each other at the other end by a fixing member 7. The fixing member 7 is used only for fixing the other end portion and is not used for fixing the one end portion, and therefore the number of members for fixing the slab 3 to the floor panel 2 can be reduced as compared with a conventional car of an elevator. Further, the work of coupling the floor panel 2 and the slab 3 (particularly, the work of inserting the positioning projections 6 into the positioning holes 5, plastically deforming and bending the positioning projections 6, and fixing the slab 3 to the floor panel 2) can be performed by one person, and thus the labor cost required for the assembly work of the car floor 1 can be reduced.
By providing the above-described structure, in the method of assembling the car 10 and the car 10 base of the elevator of the present embodiment, the cost required for the assembling work of the car base 1 can be reduced. Since the positions of the floor panel 2 and the slab 3 can be accurately and easily determined by the positioning projections 6 and the positioning holes 5, even if the floor panel 2 and the slab 3 are joined by one person, the slab 3 can be accurately disposed and fixed to the floor panel 2 in a short time, and the workability of assembling the car floor 1 can be improved.
The positioning hole 5 is preferably formed by punching (punching) at the time of manufacturing the bottom plate 2, and the positioning projection 6 is preferably formed by punching at the time of manufacturing the blank 3. When the positioning hole 5 and the positioning protrusion 6 are formed by punching, additional processing such as bending is not required for forming the positioning hole 5 and the positioning protrusion 6, and thus, the working time can be shortened, and the productivity is excellent. Further, as described above, when the positioning projection 6 is formed by punching, the cost required for the assembling work of the car bottom 1 can be reduced.
The other end of the bottom plate 2 and the other end of the slab 3 are fixed to each other using a fixing member 7. By using the fixing member 7, the strength necessary for fixing the slab 3 to the floor panel 2 can be ensured, and the slab 3 can be reliably fixed to a predetermined position of the floor panel 2, so that the workability of assembling the car floor 1 can be improved.
An adhesive is applied to the bonding surface 2a of the base plate 2, and the bonding surface 2a of the base plate 2 and the bonding surface 3a of the slab 3 are fixed to each other with the adhesive. By joining the slab 3 to the floor panel 2 using an adhesive, the slab 3 can be arranged and fixed at a predetermined position on the floor panel 2, and the workability of assembling the car floor 1 can be improved.
The present invention is not limited to the above-described embodiments, and various modifications can be made. For example, the above-described embodiments have been described in detail to explain the present invention in an easily understandable manner, but the present invention is not necessarily limited to the embodiment having all the configurations described. In addition, a part of the structure of one embodiment may be replaced with the structure of another embodiment. In addition, the structure of another embodiment can be added to the structure of one embodiment. Further, a part of the configuration of each embodiment may be deleted, or another configuration may be added or replaced.
