[0020] Specifically, the bridge deck floor 10 is arranged parallel to the horizontal plane.

[0021] When the lift is in operation, the lap joint assembly 20 is perpendicular to the bridge compartment floor 10, and the carrying assembly is retracted into the bridge compartment and operates along with the lift.

[0022] The usage process of the overlapping device 1 provided in this embodiment is: when the elevator stops at the nth floor structure layer 2, open the car door, flip the overlapping component 20 90° and overlap it on the floor structure layer 2, and the construction vehicle enters the floor from the car through the overlapping component 20; when switching to other floors, flip the overlapping component 20 back 90° and flip it into the elevator car, close the car door and the overlapping component 20 runs up or down with the elevator to other floors.

[0023] Furthermore, in this embodiment, the lap joint assembly 20 includes a lap joint plate 21 and two oppositely arranged protective units 22, one end of the lap joint plate 21 is rotatably connected to the bridge compartment bottom plate 10, and the two protective units 22 are respectively arranged on opposite sides of the lap joint plate 21; when the lap joint plate 21 rotates, the lap joint plate 21 drives the two protective units 22 to move; by setting the protective units 22, the safety is further improved.

[0024] Specifically, Figure 2 Taking the illustrated position as an example, two protection units 22 are respectively arranged on the left and right sides of the overlapping plate 21 .

[0025] Exemplarily, the lap plate 21 may be rotatably connected to the bridge deck floor 10 via a hinge 30; of course, the lap plate 21 may also be rotatably connected to the bridge deck floor 10 via a rotating shaft.

[0026] In an achievable method in which the lap plate 21 is rotatably connected to the bridge car floor plate 10 by means of a hinge 30, the lap plate 21 partially overlaps with the bridge car floor plate 10, one end of the hinge 30 is connected to the end of the lap plate 21 mounted on the bridge car floor plate 10, and the other end of the hinge 30 is connected to the top surface of the bridge car floor plate 10. During use, the lap plate 21 can rotate relative to the bridge car floor plate 10. When the elevator is docked at the nth floor structure layer 2, the car door is opened and the lap plate 21 is flipped 90° and overlapped on the floor structure layer 2.

[0027] The overlapping width L between the lap plate 21 and the bridge deck bottom plate 10 is in the range of 150 mm to 300 mm. In this embodiment, the overlapping width L between the lap plate 21 and the bridge deck bottom plate 10 is 200 mm.

[0028] Specifically, the overlap width H between the overlap plate 21 and the floor structure is in the range of 150 mm to 300 mm. In this embodiment, the overlap width H between the overlap plate 21 and the floor structure is 200 mm.

[0029] Exemplarily, the lap plate 21 is made of steel plate. Of course, the lap plate 21 can also be made of iron plate. In the implementation method of using steel plate for the lap plate 21, compared with the use of laying formwork, the steel plate bears a greater load than the formwork, and the same weight of materials can be transported by laying the steel plate and the floor structure layer 2, which reduces the number of transportations, saves transportation time, and increases construction efficiency.

[0030] Furthermore, the length of the lap plate 21 ranges from 800 mm to 1200 mm. In this embodiment, the length of the lap plate 21 is 1000 mm.

[0031] The width K of the lap plate 21 is in the range of 300 mm to 700 mm. In this embodiment, the width K of the lap plate 21 is 500 mm.

One end of the guardrail 221 is connected to one side of the lap plate 21, and the footboard 222 is arranged on the inner side of one end of the guardrail 221 close to the lap plate 21. By setting the footboard 222, materials can be prevented from falling during transportation, thereby further improving safety.

[0033] Specifically, the foot plate 222 is vertically arranged to the lap plate 21 .

[0034] The height G of the guardrail 221 is in the range of 1000 mm to 1500 mm. In this embodiment, the height G of the guardrail 221 is 1200 mm.

[0035] During use, when the lap plate 21 rotates relative to the bridge compartment bottom plate 10, the lap plate 21 drives the guardrail 221 and the footboard 222 to move.

[0036] Furthermore, in this embodiment, a warning film is coated on the outer wall of the footboard 222, and the warning film is red and white; by providing the warning film, the staff is warned of the boundary of the overlap assembly 20, thereby further improving safety. Furthermore, in this embodiment, a reinforcing cross bar 2211 is provided in the middle of the guardrail 221 along its extension direction; by providing the reinforcing cross bar 2211, the strength of the guardrail 221 is improved.

[0037] Specifically, a reinforcing cross bar 2211 is provided at a middle position of the guardrail 221 extending along its height direction.

[0038] The use process of the lap joint device 1 provided in this embodiment is as follows: when the elevator stops at the nth floor structure layer 2, open the car door and flip the lap plate 21. At this time, the guardrail 221 and the footboard 222 move with the lap plate 21, flip the lap plate 21 90° and overlap it on the floor structure layer 2, and the construction vehicle enters the floor from the car through the lap plate 21; when switching to other floors, rotate the lap plate 21 in the opposite direction.
