Description
Technical Field
The utility model belongs to the technical field of building structure, in particular to novel truss-like bracket for beam column connects.
Background
The bracket is also called a beam support, and refers to a placing component between the hanging beam and the cantilever in the suspension system, and the placing component is used for connecting the hanging beam and the cantilever and transferring load from the hanging beam. The existing building bracket is a wooden bracket; reinforced concrete corbels, steel corbels, and the like.
In the ancient Chinese building, the beam-column joint is provided with two members, namely a bracket and a sparrow, which are made of wood, the bracket usually plays a role of decoration, and the sparrow plays a role of bearing and transferring load, and the bracket and the sparrow are placed at the intersection of the beam and the column, so that the span of the house beam is shortened, the load force of the house beam is enhanced, the downward shearing force at the joint of the beam and the column is reduced, and the inclination of the angle between the transverse member and the vertical member is prevented. Because the wood carving component is used, the artistic building has high artistry and aesthetic property and has high artistic characteristics of Chinese buildings. However, the wood structure material has low strength, is only suitable for ancient buildings and modern partial wood buildings, and cannot be applied to modern high-rise and large-span buildings.
The reinforced concrete corbels are mostly applied to modern engineering, the reinforced concrete serving as a structural form is designed and used by people as early as the eighties of the nineteenth century, the advantages of the reinforced concrete and the reinforced concrete are combined for use, the bearing capacity is greatly improved, good plasticity and anti-seismic performance are achieved, the economic effect is obvious, and therefore later people apply the structure to the corbels.
However, the reinforced concrete corbel has partial defects in the construction process: the construction process is complicated, the construction period is long, the reinforced concrete structure usually needs to be bound with reinforcing steel bars firstly, then the concrete is poured by a formwork, and the maintenance is carried out for 14-28 days; the strength of the material is unstable, and the strength of the final structure not only depends on the strength of the material, but also is closely related to the operation of constructors, maintenance measures, the temperature and humidity of the environment and the like. The reinforced concrete bracket needs to be provided with intensive arrangement of reinforcement at bracket and strong junction in the use, influences this department wall body strength and bracket intensity to this bracket takes place local pressure-bearing easily and destroys, cuts to destroy, and the oblique compression or draw to one side destroy, the bending destroy.
At present, China is in a period of rapid urbanization development, a large number of old buildings exist in a plurality of cities, in order to endow new lives, inject new vitality, realize circulation and efficient use of the old buildings and meet the changing urban design requirements, the old buildings need to be modified on the basis of the existing buildings, new beams and laying members need to be added in the modification process of part of the buildings, and if the old buildings and the columns are connected to the beams and are not located at the same elevation, a plurality of corbels and reinforcing plates are needed. If adopt bright bracket can influence the structure pleasing to the eye, if adopt dark bracket, can influence again and produce inconvenience to the pouring concrete, influence the construction progress, use the reinforced concrete bracket not only construction cost height as shelving the component under this condition, the work progress also can very complicated moreover, consequently people adopt the steel bracket mostly under this condition.
The steel corbel is a common component in the existing building, and has the advantages of simple construction, reliable theoretical calculation, small section, high bearing capacity and the like, and is easier to apply to modification engineering. The common steel bracket has an n-shaped interface, an I-shaped variable cross section, and the n-shaped interface has the advantages of high shearing resistance and bearing capacity, simplicity in construction, light dead weight and the like, so that the common steel bracket is the conventional bracket with better performance and is often used in the conventional engineering.
