[0002] As my country's economy continues to develop, people's requirements for quality of life are also constantly improving. Elevators, as an effective means of transportation, have not only become an indispensable equipment for high-rise buildings, but are also gradually becoming a means of transportation for low-rise buildings.

[0003] The installation of elevators generally adopts the method of entering the house from the front of the existing building. Currently, it is mainly divided into: ① Flat-level entry, which is characterized by the elevator entrance set at the cantilevered balcony or kitchen, living room and other locations of the flat-level existing building, and the passengers can directly reach the corresponding floor, which can achieve barrier-free passage. ② Staggered-level entry, which is characterized by the elevator entrance on each floor set at the staircase rest platform of the existing building, and the installed elevator and the main body of the existing building are connected by a corridor. The elevator entrance is at the corner rest platform of the stairs between the two floors of the existing building, and it is necessary to go up or down half a floor to reach the destination floor.

[0004] The current way of connecting the corridor for installing elevators to existing buildings is to anchor the elevator corridor to the ring beam of the existing building. The ring beam of some buildings is far away from the exterior wall, resulting in the hinged connection between the corridor for installing elevators and the existing building, which will remove the rest platforms of some stairways, causing damage not only to the existing buildings, but also the destruction of the rest platforms will affect the safety of fire evacuation and create hidden dangers.

[0005] Therefore, there is a need for an elevator corridor beam end connection device for installing a ring beam when the ring beam is far away from the exterior wall. Utility Model Content

[0006] The utility model provides an elevator corridor beam end connecting device for an existing building, which does not damage the existing building and rest platform when the device is far away from the external wall surface.

The existing building comprises a rest platform and a ring beam located on the rest platform, and further comprises a corridor beam, an upper steel gasket and a lower steel gasket. The lower steel gasket is fittedly arranged at the bottom of the ring beam, the upper steel gasket is arranged on the upper surface of the rest platform, and the upper steel gasket is located above the lower steel gasket; the upper steel gasket is anchored and connected to the lower steel gasket by a plurality of bolts; one end of the corridor beam is hinged to the installed elevator, and the other end of the corridor beam is fixedly connected to the upper steel gasket.

[0009] Furthermore, the corridor beam includes two side beams, and the two side beams are fixedly connected by a plurality of connecting beams.

[0010] Furthermore, the rest platform includes a main platform and a decorative layer, wherein the decorative layer is located on the upper surface of the main platform; the decorative layer is provided with a mounting groove, and the width of the mounting groove is greater than the width of the side beam and the connecting beam.

[0011] Preferably, the side beam is a vertically arranged H-shaped steel, and the connecting beam is a square tube.

[0012] Preferably, the upper steel gasket and the lower steel gasket are anchored and connected by a plurality of bolts, and the ends of the upper steel gasket and the lower steel gasket are respectively connected by an equal number of bolts.

[0013] Furthermore, the two ends of the bolt are connected by nuts, namely an upper nut and a lower nut, the upper nut is locked on the surface of the upper steel gasket, and the lower nut is locked on the surface of the lower steel gasket.

[0014] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0015] When the ring beam is located on the rest platform and is far away from the external wall, the connection structure of the utility model can avoid partial demolition of the rest platform and damage to its original floor and platform, thereby ensuring the safety of the existing building and the connection strength of the elevator corridor.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the utility model in conjunction with the accompanying drawings in the embodiments of the utility model, so as to have a further understanding of the concept of the utility model, the technical problems solved, the technical features constituting the technical solutions and the technical effects brought about.

[0022] like Figure 1 and Figure 2 As shown, a device for connecting the ends of corridor beams of an existing building for adding an elevator thereto, comprises an added elevator 2, a rest platform 3 of an existing building 1, a corridor beam 5 and a ring beam 4 located on the rest platform 3, and also comprises an upper steel gasket 6 and a lower steel gasket 7. The lower steel gasket 7 is fittedly arranged at the bottom of the ring beam 4, the upper steel gasket 6 is arranged on the upper surface of the rest platform 3, and the upper steel gasket 6 is located above the lower steel gasket 7; the upper steel gasket 6 and the lower steel gasket 7 are anchored and connected by a plurality of bolts 8; one end of the corridor beam 5 is hinged on the added elevator 2, and the other end of the corridor beam 5 is fixedly connected to the upper steel gasket 6.

[0023] At present, the corridor of the additional elevator 2 is connected to the existing building 1 by anchoring the elevator corridor to the ring beam 4 of the existing building 1. Since the ring beam 4, frame beam and structural column of most existing buildings 1 are on the exterior wall of the building or not far from the exterior wall, the high-strength anchor bolts of the embedded parts and positioning parts do not need to be anchored for a long distance to reach the ring beam 4, frame beam and structural column. However, there are also some buildings where the ring beam 4, frame beam and structural column are far away from the exterior wall, resulting in the hinged connection between the corridor of the additional elevator 2 and the existing building 1, which will remove the rest platform 3 of some stairways, not only causing damage to the existing building 1, but also the damage to the rest platform 3 will affect the safety of fire evacuation and other safety hazards.

[0024] The utility model uses an upper steel gasket 6 and a lower steel gasket 7 as the connecting parts of the corridor beam 5. The lower steel gasket 7 is fitted at the bottom of the ring beam 4, and the upper steel gasket 6 is set on the upper surface of the rest platform 3, and the upper steel gasket 6 is located above the lower steel gasket 7; the upper steel gasket 6 and the lower steel gasket 7 are anchored and connected by multiple bolts 8. After connection, the upper steel gasket 6 and the lower steel gasket 7 use the ring beam 4 as the force point, and the upper steel gasket 6 and the corridor beam 5 are fixedly connected, so that the corridor beam 5 and the ring beam 4 located in the rest platform 3 are anchored and connected by bolts 8. Compared with the existing connection method, when the ring beam 4 is located on the rest platform 3 and is far away from the external wall, the connection structure of the utility model can avoid the partial demolition of the rest platform 3, and can also avoid destroying its original floor and platform, thereby ensuring the safety of the existing building 1 and the connection strength of the corridor with the elevator 2 installed. One end of the corridor beam 5 located inside the rest platform 3 is attached to the upper surface of the rest platform 3 , and the connection of the corridor beam 5 is supported by the rest platform 3 , so the connection strength and stability of the corridor beam 5 are higher.

[0025] Furthermore, the corridor beam 5 includes two side beams 51 , and the two side beams 51 are fixedly connected by a plurality of connecting beams 52 .

[0026] Furthermore, the rest platform 3 includes a main platform and a decorative layer, and the decorative layer is located on the upper surface of the main platform; the decorative layer is provided with a mounting groove, and the width of the mounting groove is greater than the width of the side beam 51 and the connecting beam 52. The mounting groove is provided in the decorative layer, and a groove corresponding to the structure of the corridor beam 5 is reserved in the decorative layer by excavation, so that the lower end of the corridor beam 5 is placed in the mounting groove of the decorative layer, thereby reducing the overall height of the corridor beam 5. After the corridor beam 5 is subsequently covered, the height of the rest platform 3 will not become too high. Moreover, the mounting groove provided at the decorative layer will not affect the load-bearing capacity of the rest platform 3.

[0027] Preferably, the side beam 51 is a vertically arranged H-shaped steel, and the connecting beam 52 is a square tube. The H-shaped steel is arranged vertically, that is, the steel plates on both sides of the H-shaped steel are placed at the top and bottom, respectively, and the side beam 51 is fixedly connected to the upper steel gasket 6 through the side steel plate at the bottom. The H-shaped steel has a low overall weight, high strength, and has a sufficient contact surface to be fixedly connected to the upper steel gasket 6.

[0028] like Figure 4 As shown, preferably, the upper steel gasket 6 and the lower steel gasket 7 are anchored and connected by a plurality of bolts 8, and the upper steel gasket 6 and the lower steel gasket 7 are connected at both ends by an equal number of bolts 8. The upper steel gasket 6 and the lower steel gasket 7 are connected by bolts 8 at both ends, and the connection stability of the upper steel gasket 6 and the lower steel gasket 7 is high.

[0029] like Figure 3 As shown, further, the two ends of the bolt 8 are connected by nuts 9, which are an upper nut and a lower nut respectively, the upper nut is locked on the surface of the upper steel gasket 6, and the lower nut is locked on the surface of the lower steel gasket 7. The two ends of the bolt 8 are respectively provided with an upper nut and a lower nut, that is, the bolt 8 anchors the ring beam 4 by pulling, thereby strengthening the connection strength between the corridor beam 5 and the existing building 1.
