Description

Assembling energy-dissipating type bean column node

Technical field

The utility model relates to a kind of bean column node, and particularly a kind of assembling energy-dissipating type bean column node being applicable to multistory & high-rise frame structural steelwork, belongs to structural engineering technical field.

Background technology

In recent years, along with the development of building science and technology, steel work is widely used in Multistory-tall building, large span spatial structure and bridge construction with the performance of its excellence.Due to the continuous generation of geological disaster, experts and scholars more and more pay close attention to the anti-seismic performance of steel building and pay attention to, and therefore, in the design stage of structure, take rationally necessary precautions against earthquakes to seem particularly important to structure.In multi and tall steel building building, normally bean column node place, position the weakest and dangerous.When structure meets with earthquake, during the destructive macroseism that especially earthquake intensity is larger, the bean column node position in structure is often because rigidity is larger, can not absorb and earthquake energy, and cause Nodes to produce excessive bending deformation, even there is brittle failure, serious threat people safety of life and property.

At present, in actual structural steelwork, the design principles " the weak component of strong node " followed still is followed in the design of steel-structure beam-column node substantially both at home and abroad, the form combined by welding, high-strength bolt or welding and bolt, is made into by bean column node to be rigidly connected or hinged.The connected node of this kind of form does not possess stronger distortion and energy dissipation capacity, cannot guarantee that distortion power consumption zone-transfer is to beam-ends position.Meanwhile, because bean column node position exists serious stress concentration phenomenon, when bearing seismic load, very easily there is brittle fracture and destroying, causing collapsing of structure.Although experts and scholars propose many specific aim measures for above problem both at home and abroad at present, as: weaken the mode such as two end sections or end employing fan structure, but not only cause the total bearing capacity of structure to decline with upper type, also may cause the Local Stability Problem of beam end simultaneously.

Summary of the invention

The purpose of this utility model is to provide a kind of assembling energy-dissipating type bean column node, and it effectively can improve the anti-seismic performance of bean column node, can realize standardized designs, suitability for industrialized production, and improves on-the-spot installation efficiency.

In order to solve the problem, the technical solution adopted in the utility model is: a kind of assembling energy-dissipating type bean column node, comprise H profile steel post and H profile steel beam, the bottom of described H profile steel beam is fixedly installed interlayer damper, described in the H profile steel beam that is fixed together and interlayer damper be mounted by means of bolts on the side of H profile steel post; And the node region being positioned at H profile steel post is provided with several stiffening ribs.

As further improvement of the utility model, described interlayer damper comprises several C-type steel group, upper plate, lower plate and side plates, and several C-type steel groups described are arranged between the upper and lower plates uniformly, and three is fixed together; Described side plate is connected with lower plate is vertical.

As further improvement of the utility model, the upper and lower edge of described H profile steel beam is fixed on H profile steel post respectively by T-shaped connector.

As further improvement of the utility model, between the lower plate of described interlayer damper and side plate, be provided with i iron curved support.

As further improvement of the utility model, described each C-type steel group is made up of back-to-back two C-type steel, and the lateral length of each C-type steel is about 3/4 of H profile steel flange of beam width.

As further improvement of the utility model, the quantity of described stiffening rib is three, it is separately positioned on the position that the top flange of H profile steel beam, the lower plate of interlayer damper and i iron curved support parallel, its thickness is about 4mm-8mm, three limits of every bar stiffening rib all adopt fillet weld form and H profile steel post to weld together, and effectively can strengthen tension and the compressive property of H profile steel post local.

The beneficial effects of the utility model are: the utility model bean column node is provided with interlayer damper, under strong earthquakes load action, energy dissipation can be carried out by the distortion of C-type steel in interlayer, available protecting is served to bean column node, substantially increase the anti-seismic performance of bean column node; Meanwhile, this novel joint is assembling type node, and can realize batch production, standardized production, site operation is convenient and swift, and construction quality is easy to ensure, effectively improves operating efficiency; There is good safety and economic and practical, especially in the region that antidetonation earthquake intensity is larger, there is higher promotional value.
