Description

Connection structure of overhanging type discharging platform and steel column

Technical Field

The utility model relates to a super high-rise building construction correlation technique field specifically is platform wire rope and shaped steel column connection structure of unloading encorbelmenting.

Background

The unloading platform is an operation platform and an operation frame which are temporarily built, is hoisted to an upper floor by means of vertical transportation equipment such as a tower crane and the like, and is mainly applied to material turnover. With the rapid development of the building engineering industry, the number of super high-rise buildings is continuously increased, the corresponding problem of the turnover of building materials becomes more important, and in the super high-rise buildings, a section steel cantilever unloading platform is a transportation platform which is relatively common in application and is applied to material transfer between floors or between floors and the ground. The traditional connection mode of the profile steel overhanging type discharging platform and the upper structure (a structural beam or a structural wall) mostly adopts pre-embedded U-shaped round steel pull rings, and the safety and the stability of the platform are ensured by the connection mode of a steel wire rope and the embedded part of the upper structure. The dead weight and the final stress of the stacked load are concentrated on the steel wire rope, and whether the connection between the steel wire rope and the structure is reliable and firm or not is concerned about the use safety of the discharging platform. If the hoisting ring is in a pre-treatment form and can only be arranged on the surface of the upper floor, the inclination angle of the unloading steel wire rope is possibly too large, and the unloading effect is influenced; if the hanging ring is fixed at the bottom of the steel beam in a welding mode, welding needs to be performed on the steel beam, and the stress effect of the steel beam is influenced to a certain extent; in addition, superstructure's boundary beam is mostly H shaped steel, and the formula of encorbelmenting platform of unloading is connected with the girder steel mostly, because the super high-rise building material of present stage is heavy objects such as reinforcing bar, steel pipe mostly, and transportation weight is big, and is also big to the atress of girder steel, probably leads to the girder steel to be bent the increase, produces adverse effect to super high-rise structure. The patent number is CN 201921013091.7's utility model discloses an anchor that is used for shaped steel formula of encorbelmenting platform wire rope of unloading, including upper structure floor and lower structure floor, the fixed platform of unloading that is equipped with in lower structure floor top, the upper and lower both sides of upper structure floor lateral wall are equipped with the through-hole respectively, be equipped with in the through-hole with through-hole matched with PVC casing coupling, two PVC casing coupling fit-in pegs graft and is equipped with the U-shaped round steel, the inboard of upper structure floor lateral wall is stretched out to U-shaped round steel straight flange, the U-shaped round steel straight flange stretches out the end and is helicitic texture, and the cooperation is equipped with the nut, the dog-ear of U-shaped round steel and the platform of unloading are connected and are equipped with wire rope. However, the PVC sleeve is embedded in the surface of the upper floor, and when the device is used, a split screw which is processed, manufactured and formed and can be pulled needs to be inserted into the PVC reserved pipe, so that the problem that the inclination angle of the unloading steel wire rope is overlarge exists. The utility model with the patent number of CN201420198177.2 discloses a novel overhanging discharging platform drawknot device, which comprises a hanging ring, a steel wire rope and a cross beam, wherein the length of the cross beam is longer than the width of a reserved door and window opening of a building, the cross beam is transversely arranged at the inner side of the reserved door and window opening, and two ends of the cross beam are close to a vertical structural column or a shear wall of the building; the lifting ring is welded on the cross beam, one end of the steel wire rope is connected with the discharging platform, and the other end of the steel wire rope is connected with the lifting ring through a detachable steel wire rope clamping head to form counter-pulling. The beam is installed before use and removed after use, can be used for multiple times and can be recycled, but brings inconvenience to operators.

Based on the above description, a need exists for a new connection mode of an overhanging type discharging platform and a connecting piece, so as to solve the problem that the stress of a steel beam is large and the steel beam is easy to bend to cause unstable structure and generate adverse effect on the structure due to the fact that the overhanging type discharging platform is connected to the steel beam in a super high-rise building.
