Description
Technical Field
[0001] The utility model relates to the technical field of steel structures, in particular to a modularized convenient connection device for top beams and columns. Background Art
[0002] Steel structures are made of steel and are one of the main types of building structures. They primarily consist of components such as beams, columns, and trusses, made from sections and plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. Components are typically connected by welds, bolts, or rivets. Due to its light weight and simple construction, steel structures are widely used in large factories, stadiums, high-rise buildings, and bridges. Steel structures are susceptible to rust and generally require rust removal, galvanizing, or coating, as well as regular maintenance. Steel is characterized by high strength, light weight, good overall rigidity, and strong resistance to deformation, making it particularly suitable for constructing large-span, ultra-high, and ultra-heavy buildings. Its homogeneity and isotropy make it an ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics. Its excellent plasticity and toughness allow for large deformation and excellent resistance to dynamic loads. Construction periods are short, and its high degree of industrialization allows for highly mechanized, specialized production. Steel structures should research high-strength steel materials to significantly increase their yield strength. Furthermore, new types of steel sections, such as H-shaped steel (also known as wide-flange steel), T-shaped steel, and corrugated steel sheets, should be rolled to accommodate the needs of long-span structures and super-high-rise buildings. Furthermore, there are lightweight steel structures with no thermal bridges. While buildings inherently lack energy efficiency, this technology uses ingenious special connectors to address the thermal bridge issue. Small truss structures allow cables and plumbing to pass through walls, facilitating both construction and renovation.
[0003] In existing steel structures, the top beam and the columns are often fixed with multiple bolts. However, this connection method has the following disadvantages:
[0004] 1) Internal threaded holes need to be opened on the top beam and columns, which have high hardness. Therefore, the processing of the top beam and columns is not easy. At the same time, multiple bolts are required for fixing, so the assembly between the top beam and columns is relatively cumbersome;
[0005] 2) Bolts are generally very thin, which results in a low connection strength between the top beam and the column. Utility Model Content
[0006] In view of the problems existing in the existing modularized convenient connection device between top beams and columns, the present utility model is proposed.
[0007] Therefore, the purpose of the present invention is to provide a modular and convenient connection device between the top beam and the column, which solves the problem that the connection between the top beam and the column in the existing steel structure requires internal threaded holes to be opened on the top beam and the column with high hardness, so the processing of the top beam and the column is not easy, and multiple bolts are required for fixing, so the assembly between the top beam and the column is relatively cumbersome; the bolts are generally very thin, so the connection strength between the top beam and the column is relatively low.

[0012] As a preferred solution of the modularized top beam and column convenient connection device described in the utility model, the modularized clean room column head plate is provided with a through hole for the fixing bolts to pass through.
