Description

Fast-assembling ground beam column structure

Technical Field

The utility model belongs to the technical field of connection of building structural columns and bottom beams, and particularly relates to a fast-assembled ground beam column structure.

Background

In the building construction process, the connection relation between the bottom beam and the structural column refers to a physical connection mode between a ground beam (also called a bottom beam, a bottom plate beam and a bottom beam) and a stand column (also called a structural column and a post), so that the stability, the safety and the bearing capacity of a building structure are ensured. This connection plays a key role in the overall structure of the building, since the connection of the bottom beams to the structural columns is responsible for transferring the upper load to the foundation, ensuring that the building can stably bear external loads.

Common connection relations between the bottom beams and the structural columns include the following: rigid connection: in rigid connection, the bottom beams and the structural columns are directly connected together by welding, bolting or other similar means to form a rigid whole. The connecting mode can effectively transfer load and provide a stable structure; semi-rigid connection: the semi-rigid connection is interposed between the rigid connection and the flexible connection. In this case, the bottom beam and the structural column may be connected by bolts, pins, or the like, but the connection is not as strict as that of a rigid connection. This may allow some minor deformation, but still maintain a high stability; and (3) flexible connection: the flexible connection allows for some relative displacement between the sill and the structural columns, typically by an elastic material, rubber pad, or the like. The connection mode can absorb part of energy under the conditions of earthquake and the like, so that the risk of structural damage is reduced; prestress connection: the prestress connection fixes the bottom beam and the structural column by applying prestress force, so that the stability and the bearing capacity of the connection are improved; and (3) foundation reinforcement connection: in some buildings, the connection of the bottom beams to the structural columns may need to be combined with a foundation stabilization system to ensure the stability and safety of the connection.

The connection between the bottom beam and the structural column in the existing building construction process has the following problems and disadvantages: the connection design is unreasonable: the low connection strength may be caused by unreasonable connection design, and a more effective connection mode is needed to ensure the stability and safety of the structure; lack of pre-fixation measures: the lack of pre-fixing measures at the bottom of the structural column may be a result of insufficient planning and preparation at the early stage of construction, taking into account the need to ensure the stability of the structural column prior to construction; the righting design is insufficient: additional righting means may not only add to the construction complexity, but may be inefficient, requiring more reliable righting systems to be designed to maintain the verticality of the structural column; safety and reliability are not sufficient: the low strength of the connection and the unstable structure column directly affect the safety and reliability of the overall structure, which may cause problems in long-term use.

Because the connection problem between the bottom beam and the structural column in the existing building construction relates to challenges in connection strength, structural column stability, safety, construction efficiency and the like, a bottom beam column connection structure form which can meet the stability and bearing performance of the structural column and has quick assembly performance is needed.
