Description
Technical field
The present invention relates to a kind of node component and preparation method, be specifically related to a kind of U-shaped steel-concrete combination beam and profile iron
The node component of pipe concrete column and preparation method, belong to building field.
Background technology
U-shaped steel-concrete composite beam is a kind of new structural members, replaces the I shape in conventional composite beam to cut with U-shaped steel
Face girder steel, it is possible to significantly improve the fire resistance of combination beam, improves the anti-bending bearing capacity under the hogging moment effect of node area, simultaneously
U-shaped steel-concrete composite beam can be accomplished wide with body of wall, and architectural effect is good, therefore has wide in Practical Project
Application prospect.The steel pipe of special-shaped steel pipe concrete post is to be formed by steel pipe or Plate Welding, and in the cross section of steel beam column composition
Casting concrete and a kind of combined member of being formed, owing to special-shaped steel pipe concrete post can be accomplished wide with body of wall, therefore exist
House has broad application prospects, current Practical Project mainly uses shaped rc columns, but owing to reinforcing bar mixes
Solidifying soil Special-Shaped Column construction is complicated, poor seismic behavior, is therefore only limitted in low-rise building structure, and special-shaped steel pipe concrete post by
Have employed steel beam column in periphery, steel beam column can make the bearing capacity of concrete and ductility obtain significantly with operative constraint concrete
Improving, can significantly improve the anti-seismic performance of structural system, special-shaped steel pipe concrete post eliminates reinforced concrete member in addition
Formwork and form removal operation, significantly improve the speed of application of structure, there is good economic benefit.Structural system middle frame
Post uses special-shaped steel pipe concrete post, when Vierendeel girder uses U-shaped steel-concrete composite beam, relates to a kind of new node even
Connect i.e. U-shaped steel-concrete composite beam and the node of special-shaped steel pipe concrete post.The cross-sectional width of special-shaped steel pipe concrete post leads to
Often and body of wall is wide, generally no greater than 200mm, U-shaped combination beam and the connection of coupled column generally use internal partition with outer every
Plate two ways, connects according to external partition, then at lower flange, the overhanging width of dividing plate is relatively big, and architectural effect is poor, it is impossible to reach
To the purpose using special-shaped steel pipe concrete post special-shaped steel pipe concrete post；Connect according to internal partition, due to Special-Shaped Column cross section
Size is less, and the existence of internal partition cannot be effectively ensured the pouring quality of node area concrete, if node area concreting is not
Closely knit, ultimate bearing capacity of joints can be reduced, cause node to occur too early destroying.
Summary of the invention
The present invention solves that existing special-shaped steel pipe concrete post is unreasonable with the connected mode of combination beam node, concreting
Quality is difficult to ensure, the bearing capacity causing node is too low, and the ductility of joint cores and energy dissipation capacity are not enough so that node is first
In the problem of other component damages, and then the node of a kind of U-shaped steel-concrete combination beam and special-shaped steel pipe concrete post is proposed
Assembly and preparation method
The present invention solves that the problems referred to above adopt the technical scheme that: assembly of the present invention include steel pipe, U-lag steel,
Concrete slab and Duo Gen reinforcing bar, steel pipe is vertically arranged, and U-lag steel is opening up, one end of U-lag steel and the outside of steel pipe
Wall connects, and the axis of steel pipe and U-lag steel centerline parallel along its length, and concrete slab horizontal set is at steel pipe
Lateral wall on, and concrete slab is positioned at the top of U-lag steel, is provided with many reinforcing bars in concrete slab.
Specifically comprising the following steps that of preparation method of the present invention
Step one, one end of U-lag steel and the lateral wall of steel pipe are connected by the way of welding；
Step 2, multiple angle steel shear keies are welded in U-lag steel；
Step 3, respectively weld a trapezoidal decks in the both sides of U-lag steel with junction, steel pipe lateral wall；
Step 4, the component node welded is transported to job site, carries out location is installed；
Step 5, by many reinforcing bar bindings above U-lag steel；
Step 6, in reinforcing bar, U-lag steel and steel pipe casting concrete.
The invention has the beneficial effects as follows: the present invention is a kind of reasonable stress, simple structure, easy construction, industrialized production mistake
The node component that journey is high, instead of traditional external partition and internal partition connected mode with two side cover plates, efficiently solves profile iron
In pipe concrete column, inner diaphragm joint is not easy to ensure the shortcoming of concrete pouring quality, solves in external partition node simultaneously and cuts
The shortcoming that face is oversize.U-shaped steel top flange uses connecting plate to be connected with special-shaped steel pipe concrete post, it is ensured that top flange interior
Power effectively passes to special-shaped steel pipe concrete post, and the internal force of lower flange then passes to chapped pipe coagulation by both sides trapezoidal decks
Earth pillar, it is to avoid the internal force of lower flange acts directly on the steel pipe of special-shaped steel pipe concrete post, makes steel pipe produce local too early
Flexing, power transmission of the present invention is clear and definite, it is ensured that the load on U-shaped steel-concrete composite beam effectively passes to special-shaped steel pipe concrete
Post, lower flange is connected with special-shaped steel pipe concrete post by both sides trapezoidal decks, while meeting intensity, column section and beam
Cross section can be accomplished and body of wall uniform thickness, without too much exposed parts, it is easy to construction and decoration.Node area ladder mentioned in the present invention
Shape cover plate is connected with steel pipe and U-lag steel, is arranged such and facilitates implementation being reliably connected of U-lag steel lower wing plate and steel pipe,
Ensure that the internal force of beam effectively passes to node.The employing edge of a wing, the U-lag steel top flange connecting plate of the present invention is connected with steel pipe,
It is arranged such and facilitates implementation the internal force of U-shaped beam upper limb and effectively pass to steel pipe.The U-lag steel lower flange width of the present invention with
Steel pipe width is identical, it is simple to beam, post width are identical, and in framework, the filled wall back rest, post are without exposing phenomenon, obtains preferably
Architectural effect.
