[0036] The present utility model provides a flat-floor entrance additional ladder structure 100. A frame structure is formed by overlapping a frame cross beam 20 and a frame vertical beam 10, and a load-bearing plate 30 is arranged on each layer of the frame structure for passengers to walk on. The load-bearing plate 30 and the entrance floor are on the same plane. After getting out of the elevator, passengers do not need to climb the stairs 70 anymore, which is more convenient and faster.

[0037] Please refer to Figures 1-3 and Figure 5 , the flat-floor entrance additional ladder structure 100 includes a frame structure, a corridor structure, a reinforcing plate 40 and a hoistway structure 80. The frame structure includes a frame cross beam 20 and a frame vertical beam 10. The frame cross beam 20 and the frame vertical beam 10 overlap each other, and the overlapping part of the frame cross beam 20 and the frame vertical beam 10 is connected by bolts to form a frame structure. The frame structure is divided into multiple layers at intervals along the vertical direction. The corridor structure includes a load-bearing plate 30. The load-bearing plate 30 is laid on each layer of the frame structure to form a corridor structure. One end of the corridor structure is connected to the landing platform of the additional elevator, and the other end of the corridor structure communicates with the living area of the existing building. The corridor structure and the entrance platform of the existing building are on the same horizontal plane; the reinforcing plate 40 is connected to the frame cross beam 20 and / or the frame vertical beam 10. The hoistway structure 80 includes a hoistway frame. The hoistway frame is connected to the frame structure, and a part of the frame cross beam 20 and the frame vertical beam 10 in the frame structure cooperate with the hoistway frame to form the hoistway structure 80. A landing platform 34 extends from one end of the corridor structure towards the hoistway structure 80. The landing platform 34 facilitates passengers to walk from the hoistway structure 80 to the entrance platform, and the landing platform 34 is connected to the hoistway frame.

[0038] In this way, the frame cross beam 20 and the frame vertical beam 10 are bolted together, which is more convenient for disassembly and connection. There is no need for welding connection, thus accelerating the assembly efficiency of the frame structure, enabling rapid construction, avoiding fires caused by welding, and also enhancing the structural strength of the frame structure. The load-bearing plate 30 on each floor of the frame structure is used for the occupants to walk on, and the corridor structure, its load-bearing plate 30, and the entrance floor are on the same plane. The corridor structure connects to the residential area of the existing building. Specifically, the corridor structure can be connected to the balcony of the existing building or to the living room of the existing building, and is designed according to the specific conditions of the existing building; the corridor structure is for the residents to enter the residential area from the hall door platform and walk on, and the corridor structure and the entrance floor are on the same plane, so that the residents can directly enter the house on the same floor, and the occupants do not need to go up the stairs 70 anymore, which is more convenient and fast. The reinforcing plate 40 is connected to the frame cross beam 20 and / or the frame vertical beam 10, which can equivalently increase the thickness of the frame cross beam 20 and the frame vertical beam 10 to enhance their torsional resistance, so as to further improve the structural strength of the frame structure. The hoistway structure 80 can share a part of the frame cross beam 20 and the frame vertical beam 10 with the frame structure, so as to save materials, make the connection between the hoistway structure 80 and the frame structure closer, and the assembly more convenient.

[0039] Specifically, three hoistway structures 80 are provided, which are respectively connected to the entrance platforms of Unit 1, Unit 2, and Unit 3. An elevator car is provided in each hoistway structure 80 to facilitate the simultaneous use by multiple occupants.

[0040] In this embodiment, reinforcing plates 40 are provided on both the frame cross beam 20 and the frame vertical beam 10, and multiple reinforcing plates 40 are provided on each frame cross beam 20 and each frame vertical beam 10. The respective reinforcing plates 40 are evenly spaced to enhance the strength of the frame cross beam 20 and the frame vertical beam 10.

[0041] Please refer to Figures 3-4 , the load-bearing plate 30 extends horizontally, and there are multiple grooves 33 on the load-bearing plate 30. The multiple grooves 33 are evenly spaced along the extension direction of the load-bearing plate 30. The grooves 33 can improve the structural stiffness of the load-bearing plate 30 without increasing the thickness and weight of the load-bearing plate 30, enabling the load-bearing plate 30 to bear a greater weight, so as to enhance the safety of the flat-floor entrance type additional ladder structure 100. When the load-bearing plate 30 is deformed under force, each groove 33 can deform correspondingly to release stress.

[0042] In this embodiment, the groove 33 is rectangular for convenient processing and opening. In other embodiments, the groove wall of the groove 33 can also be set to be arc-shaped, that is, the load-bearing plate 30 forms a wavy structure, which can also achieve the effect of improving the support stiffness.

[0043] Furthermore, the groove 33 is formed by bending the load-bearing plate 30. In this way, the groove 33 can be directly formed by the original structure of the load-bearing plate 30 without the need for additional opening, saving material costs and processing costs.

[0044] A walking layer (not shown in the figure) is laid on the upper side of the load-bearing plate 30 (i.e., the upper surface where the passengers walk), and the walking layer is connected to the load-bearing plate 30. The walking layer can protect the load-bearing plate 30 and reduce the wear of the load-bearing plate 30 during long-term use by passengers. When the load-bearing plate 30 is provided with the groove 33, the groove 33 can also be used to accommodate the walking layer, making the connection between the load-bearing plate 30 and the walking layer closer.

[0045] Specifically, the walking layer can be formed by dry-laying cement mortar, or dry-laying ceramic tiles or wooden floors, etc., as long as it can protect the load-bearing plate 30.

[0046] Furthermore, a connecting portion 31 is provided on the side wall of each groove 33, and the connecting portion 31 is in limit abutment with the walking layer. In this way, the connecting portion 31 can improve the connection strength with the walking layer and prevent the walking layer from falling off the load-bearing plate 30.

[0047] Exemplarily, the connecting portion 31 is a protrusion 311, and the protrusion 311 protrudes into the groove 33 along the horizontal direction. The protrusion 311 is provided on the groove wall of the groove 33, and the outer wall of the protrusion 311 is part of the groove wall of the groove 33. Therefore, the setting of the protrusion 311 can increase the contact area between the groove 33 and the walking layer, thereby improving the connection strength between the walking layer and the load-bearing plate 30.

[0048] It can be understood that in other embodiments, the connecting portion 31 can also be set to a structure other than the protrusion 311. For example, a recessed structure is opened on the groove wall of the groove 33, which can also increase the connection area between the groove wall of the groove 33 and the walking layer. Or, structures such as steps and flanges are provided on the groove wall of the groove 33, and are not limited to the above-mentioned protrusion 311 structure.

[0049] While a walking layer is provided on the upper side of the load-bearing plate 30, a light strip (not shown in the figure) is also arranged on the bottom surface of the load-bearing plate 30 to form the ceiling of the adjacent lower-level corridor structure. That is to say, the load-bearing plate 30 can also be used as a ceiling, and there is no need to additionally install a ceiling in the frame structure, simplifying the frame structure and saving the material cost of the ceiling.

[0050] Connection holes 32 are opened at both ends in the length direction of the load-bearing plate 30, and connecting members 50 are inserted through the connection holes 32. The load-bearing plate 30 is connected to the frame cross beam 20 and / or the frame vertical beam 10 through the connecting members 50. Both ends of the load-bearing plate 30 are connected to the frame cross beam 20 and the frame vertical beam 10, and its fixation is more stable.

[0051] Preferably, the connecting hole 32 is set as an oblong hole, and the oblong hole can provide a moving amount for the connecting member 50 along the length direction of the oblong hole. That is to say, the connecting member 50 can move within the oblong hole to adjust its own position. When there is a positional tolerance, it is ensured that the connecting member 50 can be smoothly connected to the adjacent structure.

[0052] Please refer to Figure 6 , further, the connecting member 50 passes upward through the load-bearing plate 30 from the bottom surface of the frame cross beam 20 that abuts against the load-bearing plate 30 and extends into the walking layer. That is to say, the connecting member 50 is connected to the frame cross beam 20, the load-bearing plate 30, and the walking layer at the same time to further enhance the connection tightness between the walking layer and the load-bearing plate 30.

[0053] In this embodiment, the connecting member 50 is set as a bolt structure, which has stable installation and is convenient for disassembly and assembly. In other embodiments, the connecting member 50 can also adopt a connecting structure such as a screw.

[0054] Each frame vertical beam 10 includes two first wing plates 11 and one first web plate 12. The first wing plates 11 and the first web plate 12 are perpendicular to each other, and both ends of the first web plate 12 are respectively connected to the middle parts of the two first wing plates 11 to form a frame vertical beam 10 with an I-shaped cross-section. At least one first wing plate 11 of each frame vertical beam 10 is connected with a reinforcing plate 40; each frame cross beam 20 includes two second wing plates 21 and one second web plate 22. The second wing plates 21 and the second web plate 22 are perpendicular to each other, and both ends of the second web plate 22 are respectively connected to the middle parts of the two second wing plates 21 to form a frame vertical beam 10 with an I-shaped cross-section. At least one second wing plate 21 of each frame cross beam 20 is connected with a reinforcing plate 40. The I-shaped frame vertical beam 10 and the frame cross beam 20 have good torsional strength, and the space between the wing plates (including the first wing plates 11 and the second wing plates 21) can facilitate the installation of the reinforcing plate 40.

[0055] The reinforcing plate 40, the frame vertical beam 10, and the frame cross beam 20 are all connected by a plurality of bolts to ensure stable connection between the two.

[0056] A connecting plate 23 is provided at the end of the frame cross beam 20. One end of the connecting plate 23 is connected to the second web plate 22, and the other end extends between the two first wing plates 11 of another frame cross beam 20 and is clamped with the two first wing plates 11. Preferably, the end face in the length direction of the connecting plate 23 abuts against the first web plate 12, and the two side faces in the width direction of the connecting plate 23 abut against the two first wing plates 11. The two first wing plates 11 and the first web plate 12 clamp the connecting plate 23 from three directions, thereby improving the connection strength between the connecting plate 23 and the frame vertical beam 10.

[0057] A plurality of frame cross beams 20 located on the same plane are connected to each other, and at least two parallel frame cross beams 20 are connected by three mutually parallel reinforcing frame cross beams 24 at the bottom surfaces, and the reinforcing frame cross beams 24 are vertically arranged with the frame cross beams 20 connected to both ends of the reinforcing frame cross beams 24. The reinforcing frame cross beams 24 can reinforce the connection strength between the two frame cross beams 20, so as to further improve the overall structural stiffness of the frame structure and enhance its durability and safety.

[0058] In addition, the flat floor entrance type elevator adding structure 100 further includes a canopy frame 60 and a staircase 70. There are a plurality of canopy frames 60, and the plurality of canopy frames 60 are evenly spaced and connected to the frame cross beams 20 for stably supporting the canopy. The staircase 70 can supply passengers to walk when the elevator is in a stopped state (such as a power outage or maintenance).

[0059] Please refer to Figures 7-9 , the hoistway structure 80 includes hoistway vertical beams 82, hoistway cross beams 81 and corner braces 90. There are a plurality of hoistway vertical beams 82, and the plurality of hoistway vertical beams 82 are arranged in parallel at intervals. The hoistway cross beams 81 are perpendicular to the hoistway vertical beams 82. There are a plurality of hoistway cross beams 81, and the plurality of hoistway cross beams 81 are arranged in parallel at intervals. Both ends of each hoistway cross beam 81 are respectively connected to two hoistway vertical beams 82; the corner brace 90 includes a first support plate 91 and a second support plate 92. The first support plate 91 and the second support plate 92 are connected, and the first support plate 91 and the second support plate 92 are integrally arranged. In this embodiment, specifically, they are vertically arranged. One of the first support plate 91 and the second support plate 92 is connected to the hoistway vertical beam 82, and the other is connected to the hoistway cross beam 81. In this way, the hoistway cross beams 81 and the hoistway vertical beams 82 form the basic frame of the elevator hoistway. The first support plate 91 and the second support plate 92 of the corner brace 90 are vertically arranged, so that the first support plate 91 and the second support plate 92 can respectively fit on the mutually perpendicular hoistway cross beams 81 and hoistway vertical beams 82, thereby supporting the hoistway cross beams 81 and the hoistway vertical beams 82, improving the connection strength and support strength between the two, and thus improving the overall stability of the hoistway structure 80.

[0060] Preferably, a corner brace 90 is provided at each connection point between the hoistway vertical beam 82 and the hoistway cross beam 81 to make the connection strength between each connection point balanced and further improve the structural strength.

[0061] The connection part of the first support plate 91 and the second support plate 92 is bent and forms an arc structure 93. The arc-shaped bending structure can avoid stress concentration, make the stress distribution more balanced, so that the connection between the first support plate 91 and the second support plate 92 is stronger, and avoid deformation and damage at the connection part of the two.

[0062] Of course, in other embodiments, the first support plate 91 and the second support plate 92 can also be directly connected at a right angle to reduce production costs. The provision of the knee braces 90 at the connection of each shaft vertical beam 82 and each shaft cross beam 81 can already significantly improve the structural strength of the shaft structure 80. Here, not providing the arc structure 93 in order to save costs will not affect the implementation of the technical problems in this application.

[0063] Please refer to Figure 10 , in this embodiment, the first support plate 91 is connected to the shaft cross beam 81, the second support plate 92 is connected to the shaft vertical beam 82, and the first support plate 91 is an L-shaped structure. The L-shaped structure enables the first support plate 91 to not only maintain a good fitting effect with the shaft cross beam 81, but also have at least a part extending towards the second support plate 92, thus ensuring an effective connection between the first support plate 91 and the second support plate 92.

[0064] It can be understood that, in another embodiment, the second support plate 92 can also be set as an L-shaped structure, that is to say, while the second support plate 92 is connected to the shaft vertical beam 82, it can also extend towards the first support plate 91 and ensure the connection effect.

[0065] Specifically, the first support plate 91 includes a connecting section 911 and an extending section 912 which are connected to each other (in the embodiment where the second support plate 92 is L-shaped, the second support plate 92 can also include a connecting section 911 and an extending section 912 which are connected to each other). The connecting section 911 and the extending section 912 are perpendicularly arranged to form an L-shaped structure, and at least one side of the connection between the connecting section 911 and the extending section 912 is an arc surface 94. The arc surface 94 here is similar to the arc structure 93 in the above text, and can avoid stress concentration when the connecting section 911 and the extending section 912 are stressed and twisted or bent, improve the stress sharing effect, and thus improve the overall structural strength of the knee brace 90.

[0066] In this embodiment, the direction in which the L-shaped first support plate 91 bends is defined as the inner side, and the other direction is the outer side. The inner side of the first support plate 91 has an arc surface 94, thus avoiding stress concentration on its inner side. In other embodiments, the outer side can also be set as the arc surface 94, or both the inner side and the outer side can be set as the arc surface 94.

[0067] There are at least two fixing holes 95 formed in the first support plate 91, and a connecting member 50 (which can be shared with the connecting member in the frame structure) is inserted through each fixing hole 95, and the connecting member 50 in the first support plate 91 is connected to the hoistway cross beam 81. Since the hoistway structure is subject to more lateral forces and its frequency is greater than the longitudinal force during daily use, accordingly, the number of bolt connections between the first support plate 91 and the hoistway cross beam 81 is increased to specifically improve the support effect that the knee brace 90 can provide. Correspondingly, there is at least one fixing hole 95 formed in the second support plate 92, and a connecting member 50 is inserted through each fixing hole 95, and the connecting member 50 in the second support plate 92 is connected to the hoistway vertical beam 82. When the longitudinal force is small, the number of connecting members 50 between the second support plate 92 and the hoistway vertical beam 82 is correspondingly reduced to reduce the material cost and the processing cost.

[0068] Specifically, the connecting member 50 is a bolt. Through the cooperation of the bolt and the nut, it is convenient to disassemble and assemble, and the connection strength is high. Of course, in other embodiments, structures such as screws can also be selected, and it is not limited to the cooperation structure of the nut and the bolt. Preferably, in this embodiment, bolts with a diameter greater than 12 mm are used to ensure that the strength of the connecting member 50 meets the standard.

[0069] In this application, in order to improve the structural stiffness of the hoistway cross beam 81 and the hoistway vertical beam 82 itself, considering the comprehensive cost and the convenience of installing the knee brace 90, the hoistway vertical beam 82 is selected as an I-shaped beam. Specifically, each hoistway vertical beam 82 includes two third flange plates 821 and one third web plate 822. The third flange plates 821 and the third web plate 822 are perpendicular to each other, and both ends of the third web plate 822 are respectively connected to the middle parts of the two third flange plates 821 to form a hoistway vertical beam 82 with a cross section in the shape of an I (also known as an H shape). This type of hoistway vertical beam 82 has good torsional strength, and the space between the third flange plates 821 and the third web plate 822 can facilitate the installation of the knee brace 90.

[0070] The side of the third flange plate 821 close to the third web plate 822 is the inner side, and at least part of the hoistway cross beam 81 is connected to the inner side of the third flange plate 821. Therefore, part of the hoistway cross beam 81 is located in the area surrounded (not completely surrounded to form a closed area here) by the third flange plate 821 and the third web plate 822, improving the space utilization rate and reducing the occupied space.

[0071] Please refer to Figure 11, corresponding to the hoistway vertical beam 82, the hoistway cross beam 81 includes two fourth wing plates 811 and a fourth web 812. The fourth wing plates 811 and the fourth web 812 are perpendicular to each other, and both ends of the fourth web 812 are respectively connected to one end of the same side of the two fourth wing plates 811 to form a hoistway cross beam 81 with a C-shaped cross-section. The side of the fourth wing plate 811 away from the fourth web 812 is the outer side; the fourth web 812 is connected to the inner side of one of the third wing plates 821, the first support plate 91 is connected to the outer side of the fourth wing plate 811, and the second support plate 92 is connected to the inner side of the other third wing plate 821. In this way, the matching degree of the hoistway cross beam 81 and the hoistway vertical beam 82 is higher. The fourth web 812 of the hoistway cross beam 81 just fits against the third wing plate 821 of the hoistway vertical beam 82, thus forming a connection. And because the hoistway cross beam 81 and the hoistway vertical beam 82 are perpendicular, the third wing plate 821 and the fourth wing plate 811 are also perpendicular. At this time, the mutually perpendicular first support plate 91 and the second support plate 92 in the knee brace 90 can just be connected to the vertically arranged third wing plate 821 and the fourth wing plate 811 to realize the reinforcement of the hoistway cross beam 81 and the hoistway vertical beam 82.

[0072] The hoistway structure 80 further includes a hoistway diagonal beam 83. The hoistway diagonal beam 83 is arranged at an angle with the hoistway cross beam 81 and the hoistway vertical beam 82, and each end of the hoistway diagonal beam 83 is connected to two adjacent hoistway vertical beams 82 through at least two connecting pieces 50. The hoistway diagonal beam 83 can further improve the structural strength of the frame formed between the hoistway cross beam 81 and the hoistway vertical beam 82, transfer the stress on the adjacent hoistway vertical beams 82, and improve the overall structural strength of the hoistway structure 80. At the same time, the two connecting pieces 50 further improve the connection stability between the hoistway diagonal beam 83 and the hoistway vertical beam 82 bracket, and prevent relative rotation between the hoistway diagonal beam 83 and the hoistway vertical beam 82.

[0073] In this embodiment, two fixing holes 95 are formed in the hoistway diagonal beam 83. The two fixing holes 95 are arranged staggeredly in the height direction. Each fixing hole 95 is respectively penetrated by a connecting piece 50 to realize the connection with the hoistway vertical beam 82.

[0074] Preferably, the cross-section of the hoistway diagonal beam 83 is L-shaped to improve the structural strength of the hoistway diagonal beam 83 itself.

[0075] Compared with the prior art, the frame cross beam 20 and the frame vertical beam 10 of the utility model are connected by bolts, which is more convenient for disassembly and connection. There is no need for welding connection, which speeds up the assembly efficiency of the frame structure, enables rapid construction, avoids fires caused by welding, and also improves the structural strength of the frame structure. The load-bearing plate 30 on each layer of the frame structure is used for the crew to walk on, and the load-bearing plate 30 and the entrance floor are on the same plane, so that the crew does not need to climb the stairs 70 anymore, which is more convenient and fast. The reinforcing plate 40 is connected to the frame cross beam 20 and / or the frame vertical beam 10, which can equivalently increase the thickness of the frame cross beam 20 and the frame vertical beam 10 to enhance their torsional resistance, thereby further improving the structural strength of the frame structure. In addition, a walking layer for walking is provided on the load-bearing plate 30, and a light strip is also provided on the bottom surface. The additional load-bearing plate 30 can not only serve as the floor for the crew to walk on, but also as a ceiling, eliminating the need for an additional dedicated ceiling structure and saving material costs.

[0076] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0077] The above-described embodiments only represent several implementation manners of the utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
