Description

Steel building universal nodes device

The utility model relates to the post girder connection device of a kind of steel frame construction universal building of building field.

Current, steel frame construction architectural design scheme and construction are applied in the construction aspect in airport, station, harbour, stadiums, factory building and high-rise superelevation layer house, have been of common occurrence.This is the building facilities owing to steel frame construction, and overall fund input is lower, short construction period, and reliable in quality can satisfy advantages such as different floor heights, span, requirement of strength again.It is applied.Yet the post in the steel frame construction, girder connection Design of device and construction have also become the important topic of this technology.On the node apparatus structural form, existing board-like, the level of vertically putting more energy into put more energy into board-like, horizontal triangle put more energy into board-like, external partition formula, internal partition formula etc., because the form of structure of steel column, girder steel is more, the structural form of node apparatus also is varied, in fact, all there are some shortcoming and defect in existing node apparatus, and it is as follows to lift row:

It is board-like vertically to put more energy into: placing of concrete is convenient, but the stress on the beam shaped steel edge of a wing will be by the column type steel edge of a wing and the transmission of vertically putting more energy into, and moving towards of stress is unreasonable.

Level is put more energy into board-like: though force path is simple and clear, intensity is reliable, can run into obstacle when concrete casting, causes steel column concrete casting quality not ideal enough, and construction is complicated.

Horizontal triangle is put more energy into board-like: be to change horizontal stiffener into triangular form in order to improve concrete pouring quality, but its power transmission will be by the web of post, thereby produce stress and concentrate, so stress is adjusted and calculation of Tensile Strength complexity comparatively.

The external partition formula: this component form is to more convenient at the inner placing of concrete of square, round tube steel column, but square, the outside placing of concrete of round tube steel column is just inconvenient, also must perforate just can be beneficial to concrete pouring on horizontal baffle, the inconvenience construction.

The internal partition formula: the shaped steel fiber stress transmission to beam is comparatively reasonable, when the inner placing of concrete of steel pipe column, also will perforate on internal partition, and technology bothers.

The purpose of this utility model is: at above-mentioned defective and deficiency, provide a kind of safe and reliable, constructing operation is simple, quick, it is laborsaving to economize material, reduces cost and node apparatus that can be general.

The purpose of this utility model is to realize like this, a kind of steel building universal nodes device, be made up of steel corbel, steel column, girder steel, steel corbel comprises node junction plate, web, gusset plate, and the node junction plate of steel corbel adopts flute profile shaped steel and web and gusset plate to fix as one.According to the needs of architectural design, angle post, Bian Xiangzhu, intermediolateral column, identical shaped steel corbel can install more than one on the steel column.With reference to the design stress requirement, the web of steel corbel can install more than one.Steel corbel can preset bolt hole on the node junction plate of flute profile shaped steel shape when batch production is produced.

According to different design of building structures, the shape of steel column can be the shaped steel of square, circular, heterotype tubing or I-shaped, H shape, flute profile.When steel column adopts square, circular, heterotype tubing, can in managing, it become steel concrete post by concrete perfusion.In addition, can also become steel concrete post at the outside placing of concrete of steel column.

The shape of girder steel can be square, circular, heterotype tubing or I-shaped, the shaped steel of H shape, flute profile.Equally, according to the design of building structures requirement, that girder steel adopts is square, circular, during heterotype tubing, can become steel concrete beam by concrete perfusion in it is managed.In addition, can also become steel concrete beam at the outside placing of concrete of girder steel.

Owing to adopt such scheme, particularly adopt flute profile shaped steel as the node junction plate, during design, as long as the channel-section steel internal diameter size is slightly larger than the outside dimension of girder steel port, in the construction hoisting process, girder steel is located node and is connected in the board slot.Two of flute profile shaped steel helped into about two backers, restricted that girder steel is left and right to be moved, as long as install a high strength double-screw bolt, can finish post girder connection operation.Node apparatus is used and to be able to generalization like this, and is simple in structure, and construction safety reliable, reduce operation, simplify install, to economize material laborsaving.The economic indicator that improves builing industry is played positive role.

Below in conjunction with the embodiment accompanying drawing structure of the present utility model is described:

Fig. 1 is the utility model: the steel corbel of steel building universal nodes device, steel column, girder steel organigram;

Fig. 2 be steel corbel be packed on the circular steel column and with the organigram of girder steel combination;

Fig. 3 is the structural representation that the node junction plate of steel corbel adopts flute profile shaped steel and web and gusset plate to fix as one;

Fig. 4 is the vertical view of steel corbel, steel column, girder steel node apparatus;

Fig. 5 is the schematic diagram that steel corbel installs two blocks of webs.

By Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 as can be known, the utility model is made up of node junction plate 1, web 2, gusset plate 3, steel column 4, girder steel 5 and bolt hole 6.Node junction plate 1 adopts flute profile shaped steel and web 2 and gusset plate 3 affixed one to be combined into steel corbel as can be seen in Fig. 1, Fig. 2, Fig. 3.Need according to different designs, can install an above steel corbel (see figure 4) on the steel column 4.Equally also can be according to designing requirement, for satisfying stress, shearing and moment of flexure transmission, the web 2 of steel corbel can install an above (see figure 5), is convenient to solve the problem that stress is concentrated.

Two of the utility model embodiment sees accompanying drawing 2.Steel column 4 is a circular pipe, and the gusset plate 3 of steel corbel is in order to be packed in obediently on the steel column 4, and gusset plate 3 can be processed into arc, and the radian size is formulated according to steel column 4 external arc, and same node junction plate 1 and gusset plate 3 affixed port position are also made arc.
