Description
Technical Field
The utility model relates to the technical field of steel column construction, in particular to a steel column supporting and positioning device and a buried foundation type steel column one-step forming structure.
Background
In recent years, with the acceleration of urban progress and continuous progress of building technology in China, the number and scale of high-rise buildings are rapidly increased. Under the background, the steel-concrete combined structure is taken as a building structure form with high efficiency, economy and excellent performance, and is gradually becoming an important choice in modern high-rise building design and construction. In particular in frame column structures, the use of stiff steel columns is becoming increasingly widespread. The structural form organically combines the steel with the concrete, fully exerts the advantages of high strength of the steel and strong pressure resistance of the concrete, and has the following remarkable advantages:
1. The bearing capacity is strong, the bearing capacity of the steel column is obviously improved through the high-efficiency stress characteristic of steel, and the high requirement of high-rise buildings on structural strength can be met.
2. The construction section size is small, compared with the traditional reinforced concrete column, the section size of the stiff steel column is smaller, the material consumption is effectively reduced while the bearing capacity is ensured, and the self weight of the building is reduced.
3. The indoor space is increased, the available space inside the building is increased due to the reduction of the cross section size of the column, and more flexibility is provided for building design.
However, in practical engineering applications, the design and construction of the toe joint of a stiff steel column still face some challenges. At present, most steel columns of high-rise buildings adopt a form of embedded foundation type rigid column foot nodes, the construction of the nodes is usually completed through secondary pouring, specifically, the construction process is divided into two stages, namely, firstly, the first concrete pouring is carried out after column foot positioning anchors are installed until the bottom plate is reached, and after the concrete reaches the design strength requirement, the steel columns are installed again, and the second concrete pouring is carried out to complete the part above the bottom plate. Although this construction method can ensure stability of the column foot node to some extent, there are obvious disadvantages:
1. The steel column is difficult to position and easy to shake after being installed, namely, when the steel column is installed, the steel column is difficult to accurately align to a preset anchor bolt position due to the fact that uneven or dimensional deviation exists on the surface of the poured foundation concrete, and after the steel column is installed, if the fixing measure is not in place, shaking can occur due to the action of external force (such as wind load or construction vibration).
2. And the construction period is long, and the concrete pouring is required to be completed twice, so that the whole construction time is prolonged, and the engineering progress is influenced.
3. Construction joints are easy to generate, namely the construction joints can be formed at the interface between two pouring processes, so that the quality of the joint part is difficult to ensure completely.
4. The quality of the foundation is improved, and the risks of leakage, cracking and the like are increased due to the existence of the construction joint, so that the integrity and durability of the foundation are weakened.
5. Potential safety hazards, namely, if the construction joint is improperly processed, the problems of reduced basic bearing capacity and the like can be caused, and the safety of the whole structure is threatened.
