Description

A conversion base connection structure

technical field

The utility model relates to the technical field of conversion and application of construction tower cranes, in particular to a conversion foundation connection structure.

Background technique

Tower cranes are referred to as tower cranes for short, also known as tower cranes. A rotating crane with a boom mounted on the upper part of a towering tower has a large working space and is mainly used for vertical and horizontal transportation of materials in building construction and installation of building components. It consists of three parts: metal structure, working mechanism and electrical system. The foundation of the tower crane is the foundation of the tower crane. Practice has proved that many major safety accidents are caused by problems with the foundation of the tower crane. It is a factor that affects the overall stability of the tower crane. Important factors, however, the current conversion base connection structure has many shortcomings, such as high manufacturing cost, low bearing pressure, and poor connection performance. Therefore, we propose a conversion base connection structure for the above problems.

Utility model content

In order to achieve the above purpose, the utility model adopts the following technical solutions: a conversion foundation connection structure, at least including tower body standard joints, connecting corbels, upper ring beams, safety beams, tie beam top plates, reinforced longitudinal beams and embedded parts; The top plate of the tie beam is arranged at the bottom of the whole body and installed horizontally; the reinforcing longitudinal beam is vertically arranged on the lower side of the top plate of the tie beam, and is located on both sides of the standard section of the tower body; the standard section of the tower body is arranged on the top plate of the tie beam The middle of the tower body standard section is connected by thread; the embedded part is embedded in the top plate of the tie beam and the inside of the reinforced longitudinal beam; the safety beam is set at the bottom of the reinforced longitudinal beam and is located at the end of the tower body standard section The upper ring beam is arranged at the corner of the tower body standard section and the top plate of the tie beam, and is installed vertically on the upper side of the top plate of the tie beam; the connecting corbel is installed on the upper side of the upper ring beam.

As an optimized technical solution of the utility model: the safety beam is anchored to the bottom surface of the reinforced longitudinal beam and supports the standard section column of the tower body; the connecting corbel is welded to the vertical bar of the standard section of the tower body, and is connected to the upper ring beam by high-strength bolts The upper ring beam is a square ring beam assembled and welded by welded H-shaped steel, which is anchored in the top plate of the tie beam through high-strength anchor bolts pre-embedded in the reinforced longitudinal beam.

Compared with the prior art, the beneficial effect of the utility model is: the connecting corbel is welded with the vertical bar of the standard section of the tower body, connected with the upper ring beam by high-strength bolts, the connecting corbel directly bears various loads of the tower crane, and the load Passed to the upper ring beam, the upper ring beam is a square ring beam welded by welding H-shaped steel, anchored to the top plate of the tie beam through the high-strength anchor bolts embedded in the reinforced longitudinal beam, and its function is to transfer the tower crane load transmitted by the corbel It is transferred to the reinforced longitudinal beam. In order to facilitate the installation of the ring beam, the ring beam is divided into two symmetrical structures, which are connected by high-strength bolts on site. Considering that the connection weld between the corbel and the vertical bar of the standard section of the tower crane is on-site vertical welding, and To bear the dynamic load, in order to ensure the safety of the tower crane, two safety beams are set on the bottom of the reinforced longitudinal beam.
