Top span beam for prefabricated building

Abstract

The invention discloses a topspan beam for a prefabricated building. The beam comprises a support clamping seat, the support clamping seat is welded with one end of a curved beam through a welded joint, the other end of the curved beam is integrally formed with a straight beam, a fixing seatis connected to one side of a circular plate through a threaded post, and the other side of the circular plate is fixedly connected to a contact plate by a spring. Through the cooperation clamping of the straight beam and an embedded beam, the transverse length of the span beam can be conveniently finely adjusted during the installation process, the overall adjustability is increased, through asymmetric cooperation fixing ofa clamping bolt and the fixing seat, a transverse position conveniently locks the support clamping seat on a beam column, a telescopic tube is arranged to facilitate the adjustment of the protruding position of a positioning folding plate, thereby facilitating the fixing of the support clamping seat of a longitudinal position,the positioning folding plate is arranged to facilitate the adjustment of a folding angle of the positioning folding plate, the beam can be convenientlyapplied to the fixing of beam columnsof different shapes, the overall structure is easy to disassemble, the disassembly and assembly are convenient, and the fixing is good.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a top span beam for prefabricated buildings. Background technique [0002] Manufacture of prefabricated buildings is prefabricated building materials in the factory, and then transported to the construction site for assembly. This will be a great revolution faced by my country's construction and building materials industry at the turn of the century. Steel will be used in prefabricated buildings. , steel is also widely used in other construction industries due to its high hardness, corrosion resistance and long service life. It is especially important in use, and the current steel structure top span beam adopts a simple and basic structural form, its overall adjustment is poor, and the length of the span beam cannot be fine-tuned, and the span beam is generally used in conjunction with the beam column, and the span beam Fixing with beams and columns needs to overcom...

[0002] Manufacture of prefabricated buildings is prefabricated building materials in the factory, and then transported to the construction site for assembly. This will be a great revolution faced by my country's construction and building materials industry at the turn of the century. Steel will be used in prefabricated buildings. , steel is also widely used in other construction industries due to its high hardness, corrosion resistance and long service life. It is especially important in use, and the current steel structure top span beam adopts a simple and basic structural form, its overall adjustment is poor, and the length of the span beam cannot be fine-tuned, and the span beam is generally used in conjunction with the beam column, and the span beam The fixation between the beam and the column needs to overcome the lateral force and shear force, but today's prefabricated span beams often ignore these, and cannot achieve both horizontal and vertical fixation, and the installation is complicated and difficult to disassemble
