Description
Technical field
The present invention relates to civil engineering new structure technical field, be specifically related to a kind of dark beam of combination of pre-buried shaped steel.
Background technology
Along with China's rapid development of economy, Development of China's Urbanization is accelerated day by day, and house house stands in great numbers like the mushrooms after rain in city.In the design of civilian construction, often run into and arrange that the situation of large space separated by partition wall on floor, because partition wall can not directly be placed on floor, so designer often arranges secondary beam under partition wall during structure design, under can avoiding partition wall like this, floor is destroyed, but secondary beam can cannot be avoided being arranged in the place such as parlor, bedroom, and reveals at the bottom of plate.If these issue handlings are bad, the using function in house may be made to have a greatly reduced quality, as: the clear height reducing house, is unfavorable for interior decoration, have impact on the attractive in appearance of house, and the flexibility of the compartment is restricted, waste material etc.
In order to arrange the adverse effect that secondary beam brings to house using function under solving partition wall, designer makes secondary beam into dark beam.Because dark beam is hidden in a kind of primary structure member in plate class A of geometric unitA or concrete wall class A of geometric unitA completely, its method for designing places at dark Liang Chu the load that sufficient stressed vertical muscle transmits to bear partition wall and floor, its existence can solve the subproblem that secondary beam brings, as: smooth at the bottom of plate, house clear height, house are attractive in appearance, the flexibility etc. of the compartment; But by the supporting capacity of existing dark beam and rigidity limited, often can not meet design requirement.Therefore, in order to solve the series of problems that in current compartment, space is brought more comprehensively, better, invention introduces a kind of dark beam of combination of pre-buried shaped steel.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of dark beam of combination of pre-buried shaped steel is provided, each doing his best to make the material of combination, collaborative work, improve the total bearing capacity that steel-concrete combines dark beam significantly, effectively improve the rigidity of component, have that depth of section is little, stress performance good, the compartment is flexible, be beneficial to the advantages such as finishing, the construction applications such as highrise building and residential houses can be widely used in.
The technical solution used in the present invention is: a kind of dark beam of combination of pre-buried shaped steel, comprise girder steel, concrete slab, transverse reinforcement, longitudinal reinforcement and " U " shape distributing bar, described girder steel is preset in concrete slab, " U " shape distributing bar is provided with between described concrete slab and steel beam web plate, below the top flange that in described concrete slab, transverse reinforcement is welded on girder steel and above bottom flange, the upper and lower flange width of described girder steel can wait and can not wait, and described steel depth of beam is equal with the thickness of concrete slab.
" U " shape distributing bar is adopted to connect as shear connector between the armored concrete slab of the dark beam of described combination and girder steel.In
As preferably, described girder steel adopts weld type girder steel or hot-rolling H-shaped girder steel.
As preferably, described " U " shape distributing bar can adopt peg to replace.
As preferably, described " U " shape distributing bar is connected with steel beam web plate to adopt and welds.
In described concrete slab, transverse reinforcement is connected with girder steel to adopt and welds, and is welded on the upper and lower edge of a wing of girder steel by transverse reinforcement in plate.
Principle illustrates: the dark beam of combination of pre-buried shaped steel, transverse reinforcement in plate and " U " shape distributing bar are welded to the overall performance that girder steel both can improve component, also can complete the compound action of beam and plate, both guarantees cooperative bearing, co-operation, simultaneously owing to considering the compound action of beam and plate, significantly can improve the strength and stiffness of dark beam, material can also be saved to a certain extent; In addition, can also prevent girder steel belly concrete from occurring larger slippage or throwing off with girder steel at girder steel belly welding " U " distributing bar (also can replace with Welded-Stud Conectors); The deck-molding of the dark beam of combination of pre-buried shaped steel is identical with concrete slab thickness, architecture indoor not only can be fully demonstrated not appear secondary beam and effectively increase interior net storey height, reduce the effect of structure floor height to greatest extent, but also the flexibility in indoor separation space can be increased, this invention can well solve the deficiencies in the prior art.
Some is also had to illustrate herein: 1, in the present invention, the upper and lower edge of a wing of weld type girder steel etc. does not mainly consider in construction and is convenient to concrete building, and hot rolling H steel also can be adopted as required to replace.2, due to the acting in conjunction of beam, plate, the connection of reinforcing bar and girder steel in plate is relied on, so the quality of welding is guaranteed when reinforcing bar welds with steel beam flange.3, for prevent concrete and girder steel from throwing off or slippage excessive, be provided with " U " shape distributing bar at girder steel belly, should be noted: for the ease of concreting, " U " shape distributing bar outward opening should be made.
Beneficial effect: the present invention is by girder steel and concrete co-operation, replace the load that secondary beam or existing dark joist support load partition wall and floor transmit, greatly can improve total bearing capacity and the rigidity of component, and section steel beam height is identical with concrete slab thickness, member section height can be reduced, increase effective headroom of building, reach neither impact finishing and house attractive in appearance, the effect of the flexibility of separate room can also be increased; Simultaneously due to the combined effect between different materials, give full play to the stress performance of Steel concrete, made the utilization rate of each material higher.Therefore, the dark beam of the combination of pre-buried shaped steel has a good application prospect in all kinds of building structure such as highrise building and civilian construction.
