Description

Technical Field

[0001] The utility model relates to the field of construction engineering, in particular to a keel adapter adopting an adaptive pin shaft. Background Art

[0002] Large-span steel corridors are often set up between the towers of a building complex. For the sake of architectural effect and safety, an aluminum single-plate curtain wall system is usually used at the bottom of the corridor.

[0003] However, in the installation of conventional aluminum plates, the skeleton is usually made of square tubes with a side length of 30mm or 40mm, which are welded to the main structure and the square tubes. Since the deformation of the large-span steel corridor is not a stable value but is in constant change due to changes in wind pressure, temperature, and live load during both construction and operation, this deformation will cause additional deformation and stress to the curtain wall keel. If steel keel welding is directly used, the weld may fail due to fatigue in the part with large deformation and stress. Conventional curtain wall keels only bear static loads, and this type of weld generally does not require fatigue calculation. For high-altitude large-span corridors, they are always affected by various loads, and the stress conditions are constantly changing, which affects the stress of the attached curtain wall structure. Once a problem occurs, it is very difficult to inspect and replace the high-altitude corridor curtain wall. Therefore, a keel adapter with an adaptive pin is proposed to solve the above problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a keel adapter using an adaptive pin shaft, which has the advantages of ensuring structural safety and being able to eliminate additional stress and deformation caused to the aluminum curtain wall keel by the deformation of the main structure. It solves the problem in the prior art of directly using steel keels for welding, which may cause the weld to fail due to fatigue in the part with greater deformation and stress.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a keel adapter with an adaptive pin shaft, comprising an adapter steel plate, two upper ear plates are fixedly connected to the bottom of the adapter steel plate, a lower ear plate is arranged between the two upper ear plates, two limit bolts are fixedly connected to the upper ear plate, a pin shaft is fixedly connected between the two upper ear plates and the lower ear plate, a joint bearing is arranged between the pin shaft and the lower ear plate, a through bolt is fixedly connected to the lower ear plate, a fastening shaft end retaining ring is arranged on the outer surface of the through bolt, and a limited position flat key is arranged between the two limit bolts.

[0006] In one or more embodiments, a through hole is formed on the lower ear plate, the size of the through hole is matched with the size of the spherical bearing, and the outer surface of the spherical bearing is fixedly connected to the inner wall of the through hole.

[0007] In one or more embodiments, a through hole is formed on the upper ear plate, and the size of the through hole is matched with the size of the pin shaft.

[0008] In one or more embodiments, the inner wall of the lower ear plate is rotatably connected to the pin shaft via a joint bearing, and the pin shaft is fixedly connected to the upper ear plate via a hexagon socket countersunk screw.

[0009] In one or more embodiments, the transition steel plate and the upper ear plate are welded into a whole.

[0010] In one or more embodiments, the transition steel plate and the upper ear plate are integrally formed by stamping.

[0011] In one or more embodiments, the outer surface of the transition steel plate is coated with fluorocarbon, and the outer surfaces of the upper ear plate and the lower ear plate are both coated with fluorocarbon.

[0012] In one or more embodiments, the upper ear plate and the lower ear plate are made of 304 stainless steel.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0014] The keel adapter adopts an adaptive pin shaft, and the pin shaft can rotate around its own center point through a joint bearing. The rotation range is within the gap between the fastening shaft end retaining ring and the joint bearing. The stress of the curtain wall keel can be released when the lower ear plate is deformed in the thickness direction of the lower ear plate. At the same time, the lower ear plate can rotate around the joint bearing, and then two limiting modes can be set as needed to prevent excessive horizontal displacement or to prevent deformation from falling back. The stress of the curtain wall keel in the length direction of the lower ear plate can be released, thereby effectively releasing the additional stress of the curtain wall keel caused by the deformation of the corridor structure, preventing the aluminum plate from deforming, and avoiding the damage of the curtain wall keel and its welds due to fatigue. At the same time, the adapter has no effect on the safety of the curtain wall structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] See also Figure 1-3In this embodiment, a keel adapter using an adaptive pin shaft comprises an adapter steel plate 1, two upper ear plates 2 are fixedly connected to the bottom of the adapter steel plate 1, a lower ear plate 3 is arranged between the two upper ear plates 2, two limit bolts 4 are fixedly connected to the upper ear plate 2, a pin shaft 5 is fixedly connected between the two upper ear plates 2 and the lower ear plate 3, a joint bearing 6 is arranged between the pin shaft 5 and the lower ear plate 3, a through bolt 7 is fixedly connected to the lower ear plate 3, a fastening shaft end retaining ring 8 is arranged on the outer surface of the through bolt 7, and a limited position flat key 9 is arranged between the two limit bolts 4.

[0024] Specifically, the limit bolt 4 and the limit flat key 9 realize the two functions of preventing excessive horizontal displacement and preventing deformation and falling back. Figure 2 When the limit bolt 4 is rotated to the bottom of the limit flat key 9, it can resist the limit flat key 9, thereby preventing the limit flat key 9 from falling back. Figure 3 In the process, the limit bolt 4 is screwed to a certain distance from the limit flat key 9. When the deformation is too large, the limit bolt 4 presses against the limit flat key 9 to limit the deformation within a specified range.

[0025] In a preferred embodiment, a through hole is formed on the lower ear plate 3, the size of the through hole is adapted to the size of the joint bearing 6, the outer surface of the joint bearing 6 is fixedly connected to the inner wall of the through hole, and a through hole is formed on the upper ear plate 2, the size of the through hole is adapted to the size of the pin shaft 5.

[0026] Furthermore, the inner wall of the lower ear plate 3 is rotatably connected to the pin 5 through the joint bearing 6, and the pin 5 is fixedly connected to the upper ear plate 2 through the hexagonal countersunk screw 10. The pin 5 can rotate around the center point in a small range through the joint bearing 6 without affecting the rotation of the lower ear plate 3 around the joint bearing 6.

[0027] In one embodiment, the transition steel plate 1 and the upper ear plate 2 are welded into a whole. In a preferred embodiment, the transition steel plate 1 and the upper ear plate 2 are stamped into one piece. The outer surface of the transition steel plate 1 is coated with fluorocarbon, and the outer surfaces of the upper ear plate 2 and the lower ear plate 3 are coated with fluorocarbon. Fluorocarbon paint, as a highly efficient anti-corrosion and anti-rust coating, can effectively solve the protection problem of the surface of the steel structure and can effectively prevent the corrosion of the metal surface, thereby extending the service life of the metal surface. In other embodiments, other materials can also be coated to prevent corrosion of the metal surface and reduce friction, which is not limited here.

[0028] During implementation, the following steps are followed: the upper part of the adapter is welded to the main structure through the adapter steel plate 1, the lower ear plate 3 is welded to the curtain wall keel, the pin shaft 5 can rotate around its own center point through the joint bearing 6, and the lower ear plate 3 rotates around the joint bearing 6. At the same time, according to the position change of the limit bolt 4 and the limit flat key 9, the stress release of the curtain wall keel along the length direction of the lower ear plate 3 is achieved.

[0029] To summarize, the pin shaft 5 can rotate around its own center point through the joint bearing 6, and the rotation range is within the gap between the fastening shaft end retaining ring 8 and the joint bearing 6, so that the stress release of the curtain wall keel can be achieved when the lower ear plate 3 is deformed in the thickness direction. At the same time, the lower ear plate 3 can rotate around the joint bearing 6, and then two limiting modes can be set as needed to prevent excessive horizontal displacement or to prevent deformation from falling back, so that the stress release of the curtain wall keel along the length direction of the lower ear plate 3 can be achieved, thereby effectively releasing the additional stress of the curtain wall keel caused by the deformation of the corridor structure, preventing the deformation of the aluminum plate, and avoiding the damage of the curtain wall keel and its welds due to fatigue. At the same time, the adapter has no effect on the safety of the curtain wall structure, and solves the problem in the prior art that directly uses steel keel welding, which may cause the weld to fail due to fatigue in the part with large deformation and stress.
