Background technology
In building field, the bean column node of profile steel concrete column and reinforced concrete beam or girder with rolled steel section en cased in concrete should adopt and be rigidly connected, and the longitudinal reinforcement of beam should stretch into the post node, and should satisfy reinforcing bar anchoring requirement.The cross section type of shaped steel and the configuration of longitudinal reinforcement should be convenient to running through of beam longitudinal reinforcement in the post, should reduce the quantity that the beam longitudinal reinforcement passes steel column in the post in the design, and should not pass the shaped steel edge of a wing, also should directly not be welded to connect with shaped steel in the post; In the time must in post, reserving through hole on the shaped steel web, shaped steel web plate section loss late should be less than web area 25%; In the time must in post, reserving through hole on the shaped steel edge of a wing, should press the M of styletable least favorable combination, the supporting capacity in N checking computations preformed hole cross section, when not satisfying requirement for bearing capacity, should carry out reinforcement.
Along with a large amount of rises of steel building in China, many high-rise steel structure are built with its intensity height, from heavy and light, series of advantages such as anti-seismic performance is good, speed of application is fast, ground cost saving, floor space is little, industrialization degree is high, good looking appearance, environmental protection more and more receive various places government, large-scale steel structure company and real estate developer's attention.And in the construction work of many high-rise steel structure, important link during the connection of girder.Whether the girder type of attachment is proper, to guaranteeing the globality and the reliability of many high-rise steel structure building, to making the quality and the progress of installing, there is direct influence whole construction period and cost.
And at present; The construction of the connected node between the Liang Yuliang is complicated, and in order to satisfy the requirement of beam column rigidity, main employing welding or bolt weldering connect; Also handlebar girder steel end is cemented on the end plate; Through the connected mode of very long bolt-through rectangular steel-tube concrete column, yet these method constructions are comparatively complicated, and cost is higher.
Summary of the invention
To the deficiency that exists on the prior art; The present invention seeks to be to provide that a kind of simple structure, Stability Analysis of Structures, power transmission are clear and definite, the beam and the beam connecting node structure of quick construction; Have higher installation accuracy and construction precision, reduced construction formwork expense and operating expenses.
To achieve these goals, the present invention realizes through following technical scheme:
Beam and beam connecting node structure comprise a plurality of prefabricated panels, it is characterized in that, saidly between two prefabricated panels, are installed with splicing seams, in described splicing seams, are filled with the microdilatancy mortar, have increased the steadiness of node; Also have cast-in-place groove on the said prefabricated panel, in cast-in-place notch, be welded with group's bar, the splicing seams between two prefabricated panels is the jointing of beam, in splicing seams, is provided with the stirrup of encryption, and said stirrup is connected as a single entity two prefabricated panels through group's bar welding.
According to above-mentioned beam and beam connecting node structure, wherein, it is 0～15mm that the seam of said splicing seams is opened distance.
According to above-mentioned beam and beam connecting node structure, wherein, the degree of depth of said cast-in-place groove is 170mm, and the width of said cast-in-place groove is 250～500mm,
According to above-mentioned beam and beam connecting node structure, wherein, said prefabricated panel upper top and bottom are equipped with reinforcing bar, and said reinforcing bar extends on the prefabricated panel edge truncation surface.
According to above-mentioned beam and beam connecting node structure, wherein, also be provided with the stirrup that connects top and bottom reinforcement bars on the described prefabricated panel, increased stability.
The advantage that the present invention compared with prior art has is following:
The present invention passes through in the node part of Liang Yuliang, to fill the microdilatancy mortar, and through group's bar welding two blocks of wallboards is connected as a single entity, and has increased the node fastness; And have higher installation accuracy and a construction precision; Quick construction has reduced construction formwork expense and operating expenses, and it has simple structure, the clear and definite quick construction of power transmission; Make things convenient for the reinforcing and the transformation of building structure, but suit connects in the girder of middle-high building.
