Abstract
A cast-steel connection part used for a steel-structure building relates to a connection part used for the steel structure building. The invention solves the problems of the existing welding connection manner that the impact toughness is low; the stress is focused and the welding quality can not be guaranteed and also solves the problems of the existing rolled steel connection parts that the shape is single and the alternative is less; and the intensity and bearing capacity are lower. One side surface of a first connection plate of the invention is intersected with one side surface of a second connection plate; two adjacent side surfaces of a rib plate are respectively intersected with one side face of the first connection plate and one side surface of the second connection plate; and the rib plate, the first connection plate and the second connection plate are integrally cast for shaping. The cast-steel connection part has the advantages that the impact toughness is high; the stress is not focused and the cast quality can be guaranteed easily. The cast-steel connection part enhances the bearing capability and the intensity; the features of the cast-steel technique can be adopted to lead the connection parts to have the advantages that the shape can be various, the alternative is wide and the material can be conserved; simultaneously, the bolt prying force can be eliminated or reduced; and the adaptability is strong.
Description
Technical field
The present invention relates to a kind of connector that is used for steel building, belong to the steel building technical field.
Background technology
The high-strength light advantage of steel makes steel work be widely used in building trade, especially in airport terminal, conference and exhibition center, stadiums and the super highrise building of large span.Along with the raising of china's overall national strength and the develop rapidly of output of steel and steel smelting technique, a large amount of steel buildings are built throughout the country.
The steel frame beam column type of attachment is a key areas of steel building design.A series of earthquake disasters have in recent years proposed query to traditional steel work connected mode.Wherein, the impact toughness that is welded to connect is low, and stress is concentrated outstanding and welding quality is difficult for ensureing; And rolled steel connector shape is single, but the choice is little, bolt sled power and waste of material have inevitably occurred, and rolled steel connector intensity and bearing capacity are lower.
Summary of the invention
The objective of the invention is in order to solve low, the concentrated outstanding and difficult problem that ensures of welding quality of stress of impact toughness that existing welding connecting mode exists, and but the single choice of shape that the rolled steel connector exists is little, intensity and the lower problem of bearing capacity, and then provide a kind of cast steel connector that is used for steel building.
Technical scheme of the present invention is: a kind of cast steel connector that is used for steel building is made up of floor, first junction plate and second junction plate; Intersect a side of described first junction plate and a side of second junction plate, intersect with a side of corresponding first junction plate and a side of second junction plate respectively adjacent two sides of described floor, all have at least one bolt hole on described first junction plate and second junction plate, described floor, first junction plate and the second junction plate integral cast moulding.
The present invention compared with prior art has following beneficial effect: the present invention adopts the integral cast one-shot forming, has abandoned welding connecting mode, makes the present invention have the advantage that impact toughness height, stress dispersion and casting quality are easy to ensure; Thereby the present invention is provided with supporting capacity and the intensity that floor has improved connector by the force part at connector; But the present invention makes full use of the characteristic of cast steel technology makes connector have the advantage of the big and economical with materials in the various choice of shape, also reduces simultaneously or has eliminated bolt sled power and had the strong advantage of applicability.
