Description
Technical Field
The invention relates to the technical field of fabricated buildings, in particular to a method for bolting and welding a steel beam with a shear wall, an ear plate and angle steel.
Background
Buildings assembled from prefabricated parts at the site are called fabricated buildings. The prefabricated parts are divided into five types, namely block building, plate building, box building, skeleton plate building and rising-rise building according to the form and construction method, and with the development of modern industrial technology, the built house can be manufactured in batches like machine production. The prefabricated house components are transported to a construction site to be assembled.
Fabricated buildings have become of interest since the beginning of the 20 th century and have been realized through the sixties. The first attempt made in English, French, Soviet Union and other countries is rapidly promoted worldwide due to the rapid construction speed and low production cost of the fabricated building.
Early fabricated buildings were rather rigid and uniform in appearance. Later improvements in design have resulted in increased flexibility and versatility to allow modular construction not only in batch, but also in a wide variety of styles. The movable dwelling house is an advanced assembly type building in America, each dwelling unit is like a large trailer, and the movable dwelling house can be used only by pulling the movable dwelling house to the site by a special automobile and then hoisting the movable dwelling house to a floor cushion block by a crane to be connected with a pre-buried water channel, a power supply and a telephone system. The movable dwelling houses are provided with heating, bathroom, kitchen, dining room, bedroom and other facilities, and the movable dwelling houses can be independent into a unit and can also be connected with each other.
Shear walls are also known as wind resistant walls, seismic walls or structural walls. The wall body mainly bears horizontal load and vertical load (gravity) caused by wind load or earthquake action in a house or a structure, and the structure is prevented from being sheared (sheared) and damaged. Also known as earthquake resistant walls, are generally made of reinforced concrete.
The shear wall is divided into a plane shear wall and a barrel shear wall, and the plane shear wall is used in a reinforced concrete frame structure, a lifting plate structure and a flat slab system. In order to increase the rigidity, strength and collapse resistance of the structure, the reinforced concrete shear wall can be cast in situ or prefabricated in some parts. The cast-in-place shear wall, the peripheral beams and the columns are simultaneously poured, and the integrity is good. The cylinder shear wall is used in high-rise buildings, high-rise structures and suspension structures and is formed by enclosing of partition walls of elevator rooms, staircases, equipment and auxiliary rooms, the cylinder wall is a cast-in-place reinforced concrete wall body, and the rigidity and the strength of the cylinder shear wall are higher than those of a plane shear wall in bearing of larger horizontal load.
