Technical Field
[0001] The utility model belongs to the technical field of connecting components, in particular to a connecting structure for adding an elevator gallery bridge to an old building and the old building. Background Art
[0002] With the acceleration of urbanization, the functions and facilities of old residential areas are gradually unable to meet the living needs of residents. Among them, the lack of elevator equipment is a major problem faced by many elderly people and people with limited mobility. Therefore, adding elevators to old buildings has become one of the important measures to improve living conditions and improve the quality of life. However, since the need to install elevators in the future was not taken into account when old buildings were designed and built, adding elevators without destroying the original structure faces many technical challenges.
[0003] First, the structural strength and bearing capacity of the old building may not meet the needs of the new elevator system. Without large-scale structural reinforcement, how to safely and stably connect the elevator system to the existing structure is a technical challenge. Secondly, even if the connection problem can be solved, due to natural or man-made factors such as foundation settlement, the newly built elevator system may have displacement or settlement inconsistencies with the old building, which will further increase the structural stress, may cause damage to the connection parts, and even affect the structural safety of the entire building.
[0004] In order to solve these problems, it is necessary to develop a connection structure that can adapt to the characteristics of old buildings, is easy to install, and can withstand certain settlement differences. This connection structure must not only ensure the stability and safety of the elevator system, but also minimize the interference and damage to the old building structure, while considering economy and convenience of construction. Therefore, in response to the special needs of adding elevators to old buildings, the utility model proposes an innovative connection structure design, aiming to provide a safe and practical solution to cope with the technical and structural challenges that may be encountered when adding elevators to old communities.

DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:
[0029] See also Figure 1-3 As shown, the utility model is a connection structure for adding an elevator corridor to an old building and the old building, comprising a first connecting member 1, a second connecting member 2 and two shaft rods 3 for connecting the first connecting member 1 and the second connecting member 2. The first connecting member 1 comprises an L-shaped plate 11. The horizontal plate of the L-shaped plate 11 is provided with two rows of first through holes 12. A row of first connecting ears 13 are respectively fixed to the upper and lower ends of the outer facade of the L-shaped plate 11. The second connecting member 2 comprises a rectangular plate body 21. A row of second connecting ears 22 are respectively fixed to the upper and lower ends of the surface of the rectangular plate body 21 relative to the first connecting member 1. The second connecting ears 22 are staggered with the first connecting ears 13. After the shaft rod 3 passes through the staggered second connecting ears 22 and the first connecting ears 13, a limiting end cap 31 is respectively fixed at both ends. The first connecting member 1 is connected to the floor plate of the old building, and the L-shaped plate 11 is hung on the floor plate by expansion bolts or chemical bolts. The second connecting member 2 is connected to the additional elevator gallery, which is a steel structure. The rectangular plate 21 and the steel gallery are fixed by bolts and nuts or welding, or both.
[0030] When the second connecting member 2 is connected to the additional elevator gallery by bolts and nuts, a row of third through holes 23 is opened in the middle of the rectangular plate 21, and the bolts and nuts pass through the third through holes 23, and corresponding threaded holes are opened on the gallery steel structure.
[0031] When the second connecting member 2 is connected to the additional elevator gallery by welding, a row of reserved welding slots 24 are provided in the middle of the rectangular plate 21, and the middle of the rectangular plate 21 is connected to the elevator gallery steel structure as a whole through the row of reserved welding slots 24. The rectangular plate 21 has grooves 25 at two corners away from the first connecting member 1. The upper and lower ends of the rectangular plate 21 are respectively welded to the elevator gallery steel structure as a whole, and the second connecting member 2 is strongly connected to the additional elevator gallery as a whole.
[0032] In order to increase the connection strength between the L-shaped plate 11 and the floor plate of the old building, a row of second through holes 14 are opened on the outer facade of the L-shaped plate 11. Round holes are opened horizontally on the floor plate of the old building, and countersunk bolts or chemical bolts are inserted to connect the second through holes 14 of the L-shaped plate 11. The L-shaped plate 11 is connected to the floor plate of the old building from two perpendicular directions, and the overall connection is stable and reliable.
[0033] In order to ensure that the second connecting member 2 is subjected to downward pressure as much as possible and to increase the adjustable connection distance between the first connecting member 1 and the second connecting member 2, the insertion hole of the first connecting ear 13 is set as an oblong hole, and the insertion hole of the second connecting ear 22 is set as an oblong hole, and the first connecting member 1 and the second connecting member 2 are telescopic.
[0034] In order to enable a small range of deflection and articulation between the first connector 1 and the second connector 2, and reduce the torsional stress of the first connector 1 on the second connector 2, the radius of the shaft rod 3 is smaller than the radius of the insertion hole of the first connecting ear 13. The radius of the shaft rod 3 is smaller than the radius of the insertion hole of the second connecting ear 22. When the foundation of the newly built elevator sinks, the first connector 1 deflects downward relative to the second connector 2, avoiding the first connector 1 from generating a large torsional stress on the second connector 2, and ensuring the safety of the original building floor slab. Specific embodiment 2:
[0036] On the basis of the first specific embodiment, in order to improve the connection stability between the first connecting member 1 and the floor slab of the old building, the difference of this embodiment is:
[0037] like Figure 4 As shown, it also includes a pressing plate 4. The pressing plate 4 is provided with two rows of countersunk holes that match the first through holes 12. The pressing plate 4 and the first connecting member 1 are connected as a whole through two rows of countersunk screw nuts 5 that pass through the floor plate of the old building. The pressing plate 4 and the first connecting member 1 are located above and below the floor plate and are clamped and installed on the floor plate of the old building. The pre-tightening force of the countersunk screw nuts 5 is greater than the pre-tightening force of the expansion bolts or chemical bolts, and the connection stability is higher.
