Passengers and luggage are placed on the upper surface of the floorboard 2, and a floorboard 3 is fixed to the lower surface (joint surface 2a) opposite to the upper surface. A plurality of floorboards 3 are members that reinforce the floorboard 2 and are arranged along the joint surface 2a of the floorboard 2 so as to be parallel to each other. The baseboard 4 is provided along the periphery of the upper surface of the floor board 2 .

The floor plate 2 has a plurality of positioning holes 5 at one end. The positioning holes 5 preferably penetrate the floor plate 2 and are provided in the same number as the floor plates 3 (for example, six in FIG. 1). The positioning hole 5 is preferably formed by stamping (punching) at one end of the floor plate 2 when the floor plate 2 is manufactured.

Each floor slab 3 has a positioning projection 6 at one end.

FIG. 8 is a diagram showing the floor slab 3. As shown in FIG. The floor slab 3 is composed of a metal plate-like member (for example, a steel plate), and has a substantially U-shaped shape. and two perpendicularly intersecting faces. The floor slab 3 has a positioning projection 6 at one end of the connecting surface 3a.

The positioning projection 6 extends from the joint surface 3a, protrudes parallel to the joint surface 3a before the floor slab 3 is fixed to the floor board 2, and is bent after the floor slab 3 is fixed to the floor board 2. It engages with the positioning hole 5 of the floor plate 2 in this state. The positioning projection 6 has a size that can be inserted into the positioning hole 5 of the floorboard 2 , and is positioned inside the positioning hole 5 to engage with the positioning hole 5 when the floorboard 3 is fixed to the floorboard 2 . installed in a suitable location.

The positioning projection 6 has a bent portion 6b that is a connection portion with the joint surface 3a of the floor slab 3. As shown in FIG. The bent portion 6b protrudes parallel to the connecting surface 3a before the floor slab 3 is fixed to the floor plate 2, and is plastically deformed to form the positioning hole 5 after the floor slab 3 is fixed to the floor plate 2. It is bent almost at a right angle from the The tip portion of the positioning projection 6 beyond the bent portion 6 b is positioned inside the positioning hole 5 after the floor slab 3 is fixed to the floor slab 2 . A part of the tip portion from the bent portion 6 b may protrude from the floor plate 2 . A portion of the positioning projection 6 which is at the tip of the bent portion 6b and protrudes from the floor plate 2 is called a tip portion 6a. The positioning projections 6 are thus engaged in the positioning holes 5 .

The positioning projection 6 is made of a metal plastic material, and is made of the same material as the floor slab 3 (for example, steel plate). The positioning projection 6 has strength to the extent that it can be plastically deformed and bent by an operator's force. The positioning projection 6 is preferably formed by stamping at one end of the floor slab 3 when the floor slab 3 is manufactured.

FIG. 5 is a diagram showing the fourth step following the third step. FIG. 6 is a diagram showing the fifth step following the fourth step. The work of connecting the floor slabs 2 and 3 performed in the first to fifth steps can basically be performed by one worker.

As shown in FIG. 2, in order to assemble the car floor 1, the worker performs the following first step. The worker installs the floorboard 2 so that the joint surface 2a (that is, the lower surface) of the floorboard 2 faces upward. Then, an adhesive is applied to the joint surfaces 2a of the floorboards 2. As shown in FIG. The adhesive is applied to a portion of the joint surface 2a that contacts the floor slab 3. As shown in FIG. After that, the worker lifts the floor slab 3 to be arranged on the connecting surface 2a of the floor slab 2 so as to stand upright with respect to the floor slab 2, and the positioning hole 5 of the floor slab 2 and the positioning projection 6 of the floor slab 3 are engaged. are vertically opposed to each other.

Next, as shown in FIG. 3, the worker performs the following second step. That is, the operator lowers the lifted floor slab 3 and inserts the positioning projections 6 into the positioning holes 5 while the floor slab 3 stands upright with respect to the floor slab 2 . When the second step is finished, the positioning projections 6 are positioned inside the positioning holes 5 . A portion of the positioning protrusion 6 (tip portion 6 a ) may protrude from the floor plate 2 . Thus, the operator determines the position of the floor slab 3 with respect to the floor slab 2 .

Next, as shown in FIG. 4, the worker performs the following third step with the positioning projection 6 positioned inside the positioning hole 5. As shown in FIG. That is, the operator lays down the floor slab 3 so that the connecting surface 3 a of the floor slab 3 faces the connecting surface 2 a of the floor 2 while the positioning projections 6 are still inserted into the positioning holes 5 . At this time, the bent portion 6b of the positioning projection 6 is plastically deformed and bent. For example, the operator pushes down the floor slab 3 by applying its own weight to plastically deform the bent portions 6b of the positioning projections 6 so that the joint surface 3a of the floor slab 3 becomes the joint surface 2a of the floor plate 2. make it go

Next, as shown in FIG. 5, the worker performs the following fourth step. That is, the operator brings the entire connecting surface 3a of the floorboard 3 into contact with the connecting surface 2a of the floorboard 2. As shown in FIG. For example, the worker pushes down the floor slab 3 approximately 90 degrees to bring the entire joint surface 3 a of the floor slab 3 into contact with the joint surface 2 a of the floor board 2 , thereby pressing the floor slab 3 against the floor board 2 . The positioning protrusion 6 is bent at a substantially right angle by plastically deforming the bent portion 6b, and engages with the positioning hole 5 in a state in which the tip of the bent portion 6b is positioned inside the positioning hole 5. there is (The tips 6a of the positioning projections 6 may protrude from the floorboard 2.) In the fourth step, the positioning projections 6 are engaged with the positioning holes 5 so that one ends of the floorboards 2 and floorboards 3 are aligned. The floor slabs 3 are fixed to the floorboard 2 by bonding the floorboards 3 to the floorboards 2 by bonding the floorboards 3 to the floorboards 2 with an adhesive.

The worker repeats the work from the first step to the fourth step (FIGS. 2 to 5) by the number of floor slabs 3 . These operations can be performed by a single operator.

Next, as shown in FIG. 6, the worker performs the following fifth step. First, an operator installs the floorboard 2 to which the floorboard 3 is fixed so that the joint surface 2a faces downward. That is, the worker turns the floorboard 2 upside down so that the floorboard 3 is positioned under the floorboard 2 . Note that this work may be performed by a plurality of workers. After that, the worker inserts the fixing member 7 into the connecting hole 12 of the floorboard 2 and the floorboard 3, and fixes the other end of the floorboard 2 and the other end of the floorboard 3 using this fixing member 7 to each other. do. This work can be performed by one worker. In the fifth step, the other ends of the floorboards 2 and 3 are joined together by the fixing member 7 to fix the floorboard 3 to the floorboard 2 .

The design of the floor plate 2 may deteriorate due to the positioning projection 6 provided at one end and the fixing member 7 provided at the other end. That is, there is a concern that the design of the car floor 1 will be deteriorated due to the distal end portion 6a of the positioning projection 6 protruding from the floor plate 2 and the fixing member 7 being visible to the passengers of the elevator.
