Description

A kind of existed concrete bridge post and newly-increased steel beam connecting joint
Technical field
The utility model belongs to structural engineering technical field, is specifically related to a kind of existed concrete bridge post and newly-increased steel beam connecting joint.
Background technology
Along with the high speed development of China's modernization business, the commercial building that part the 80s and 90s builds can not adapt to new business demand at present, but due to planning or operation reason, this commercial building cannot be removed again and be reconstructed, need to carry out inside transformation to it for this reason, wherein just relate to a kind of floor displacement transformation, namely lift transformation, all remove by original floor transverse member, retain vertical member, rebuild floor by new calibration is high again, be floor displacement.
At present, the existing specification of China, standard all do not provide existed concrete bridge post and newly-increased steel beam connecting joint constructs way, and this kind of connection way can often run in a lot of improvement project, and increasing along with existing commercial building, the situation of commercial building transformation also can increase, meet this kind of connection way also just more, but, owing to not having Its Relevant Technology Standards for reference, when making so many people run into this kind of situation, often have no way of doing it, do not know how to solve, therefore, this category node connectivity problem how is scientificlly and effectively solved imperative.
Utility model content
The utility model is in order to make up the defect of prior art, provide a kind of connectivity problem solving new increasing steel beam and existed concrete bridge intercolumniation, node good integrity, anti-seismic performance is good, realize the design concept of strong node, weak component, fill up international blank existed concrete bridge post and newly-increased steel beam connecting joint.
The utility model is achieved by the following technical solution:
A kind of existed concrete bridge post and newly-increased steel beam connecting joint, comprise existed concrete bridge post, steel plate encloses cover and new increasing steel beam, described existed concrete bridge post overcoat has steel plate to enclose cover, steel plate encloses cover and is fixed on existed concrete bridge post by many high-strength bolts, described existed concrete bridge post and steel plate enclose between cover and are cast with structural adhesive layer, described steel plate encloses the cross section quadrangularly of cover, steel plate encloses cover surrounding and is respectively welded with new increasing steel beam, connects formula sash rib unidirectional for Nodes two upper and lower edges of a wing of new increasing steel beam are welded to one another connection outside described new increasing steel beam adopts.
Particularly, described steel plate encloses to overlap and adopts vertical position welding groove weldings to connect into box by four pieces of anchor plates.
Particularly, the upper and lower edge of a wing of described new increasing steel beam adopts groove welding and steel plate to enclose cover and is welded to connect, and web adopts fillet weld and steel plate to enclose cover and is welded to connect.
The beneficial effects of the utility model are: the utility model a kind of existed concrete bridge post and newly-increased steel beam connecting joint solve the connectivity problem of new increasing steel beam and existed concrete bridge intercolumniation, node good integrity, anti-seismic performance is good, at beam, Column border node place, the outer formula sash rib that connects by upper bottom flange place between girder steel and girder steel is connected to each other, make ultimate bearing capacity of joints higher than girder steel self bearing capacity, under seismic loading, plastic hinge can occur at beam-ends, thus achieve the design concept of strong node, weak component, site operation is convenient, and cost is low.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
