The present invention is a kind of a kind of novel combination construction system that is mainly formed by the steel reinforced concrete frame and the steel support combinations of arranging according to the stressed needs of structure space.Compare with existing conventional art and to have the following advantages and beneficial effect:
On joint form: section steel beam variable cross-section height and width, steel are supported on the node area frange plate and the beam column frange plate is in quadrature.The cross section mechanical characteristics is: beam and be supported on node area and all strengthened, and the cross section resistance moment increases, and section area strengthens, and node area forms firm territory.The pass of shaped steel and reinforcing bar is: the part beam steel directly is welded on the shaped steel, the not perforate of steel column frange plate, and the steel column cross section does not have and slackens; Prick post master muscle after the perforate of section steel beam cross section, but the section steel beam cross section is strengthened; The shaped steel beam main tendon is worn in the perforate of steel supporting section part, but steel supporting section tension pressure energy power does not weaken.Beam column master muscle is arranged uniform sequential, and the node area concrete is subjected to good constraint.
The present invention has improved the anti-seismic performance of node region greatly, node area shaped steel dominate, but reinforcement placement is even, reinforcing bar is by with the welding of shaped steel with intert, the cooperative bearing of reinforcing bar and shaped steel is strengthened, synergy between reinforcing bar, shaped steel and the concrete is also strengthened, and the ductility in cross section increases substantially.The present invention has given full play to the advantage of shaped steel, concrete, several different materials of reinforcing bar, has avoided the appearance of weakness in engineering of material, makes the shaped steel beam column and support the node area anti-seismic performance that forms to increase substantially.
Easy construction of the present invention, the installation of reinforcing bar and easy to connect, the depth of section that shaped steel beam column and steel support is unified in node area, and reinforcing bar directly passes the shaped steel edge of a wing or is welded in the shaped steel edge of a wing, very is convenient to the blanking and the installation of reinforcing bar; Node area does not have too much stiffener, is convenient to the connection and the concrete cast of reinforcing bar, and the construction quality of node area is easy to guarantee.
The present invention makes that by changing node area section steel beam and steel supporting section height and width node area section steel beam and steel supporting section are strengthened.The equivalent rule of utilizing cross section geometric and physical property is suitably opened shaped steel beam column and steel supporting section and is worn reinforced hole, by reasonable control percent opening, allows the frange plate of a part of reinforcing bar by shaped steel.The rigidity of section of node region has been strengthened on the one hand in design like this, has guaranteed the mechanical property in shaped steel cross section, and the interconnecting of reinforcing bar, continuity and anchoring are solved equally preferably.Concrete formwork erection position and concrete pouring passage have also made things convenient for constructing operation.
Node diagnostic of the present invention to steel column, is uniform and continuous from bottom to top clearly, and the node region that supports between section steel beam and steel column then wants the situation of combined with steel reinforced concrete to carry out the design and the adjustment in shaped steel cross section.Utilize the equivalence of cross section on mechanical property and the plasticity of shaped steel, the reinforcing bar of section steel beam is converged on the section steel beam frange plate of node region, the character in cross section is converted to relatively pure steel reinforced concrete frame cross section by the binary cross section of span centre shaped steel and steel concrete, avoids the too much reinforcing bar of node region to intert and reduces and weaken the target that is provided with of node overall performance and shaped steel.By such design, the mechanical property in the spaning middle section of section steel beam and bearing cross section will be distinguished to some extent, is typical steel reinforced concrete beam section at span centre, and then transition is for based on the shaped steel drag in standoff region, and the reinforcing bar drag is the cross section of assisting.Particularly the section steel beam standoff region cross section ductility under geological process is improved, and strong shock-resistant node target is achieved.Can apply to stride greatly, heavy burden, and high-rise, super highrise building in.
The present invention has arranged rationally on the basis of the local variable cross-section of shaped steel that section steel beam, steel support, the spatial relationship of the node region of steel column, to allow shaped steel play a part in node area by the cross section conversion bigger as far as possible, reinforcing bar is more tight with combining of shaped steel, divide to mix more on internal force and coordinate, cross section ductility improves.Simultaneously laid reinforcement binding and intersection are interted and are reserved on the locus.
Be to solve the outer rigidity problem of supporting plane, the strong axle in cross section that H shaped steel is supported places in the plane, and weak axle places outside the plane, with the cross section of less expensive obtained design need rigidity.But like this after the design, the support node edge of a wing in support node zone and the relative broad in the section steel beam node edge of a wing, it is wide to reach 560mm, the adding that steel supports this wide width wing edge member element has increased the complexity of node, node region becomes the three-dimensional cross reference, the space contradiction relations of shaped steel and reinforcing bar etc. are more outstanding, the main muscle of the part of steel column must pass the cross section performance that frange plate that section steel beam and steel support could guarantee steel column, the main muscle passage of the part of simultaneous type girder steel also hinders in the edge of a wing of supporting, and perforate means that the part of the mechanical property in cross section loses on the edge of a wing of section steel beam and support, reduces the usefulness that is provided with of shaped steel; The target of design of node is to give the shaped steel cross section that loses for change, also will strengthen the shaped steel performance of node area simultaneously relatively, guarantees the reliable drag of steel reinforced concrete frame node under the violent earthquake effect.
Compare with concrete structure, owing to disposed shaped steel in the cross section, shaped steel is with its intrinsic intensity and ductility, and shaped steel, reinforcing bar, concrete three make reinforced concrete composite structure possess the advantage that bearing capacity is big, rigidity is big, anti-seismic performance is good for working integratedly.Significantly improving of structural strength, rigidity, make that it can apply to stride greatly, heavy burden, and high-rise, super highrise building in.Stride greatly, in heavy burden and the super highrise building if use reinforced concrete structure, the member section is very big, it might influence technology arrangement, or influences function of use, adopts reinforced concrete structure just to seem very unreasonable or impossible reluctantly.And under the identical situation of load, adopt reinforced concrete composite structure, the sectional dimension of member to reduce, and the building usage space will increase.This for solve in the high building structure because of the number of plies increase, highly big, make bottom column, power increases rapidly within the walls, it is meaningful especially that corresponding requirements concrete component sectional dimension strengthens the contradiction that requires with function of use.Because the pin power of the shear resistance of shaped steel vertical muscle in the reinforced concrete member, shaped steel can suppress carrying out of member diagonal crack, pressure zone shaped steel skeleton can also make it be the three-phase pressured state by confined concrete, the fragility character of material when having improved sheared destruction greatly, thereby the reinforced concrete composite structure member has good ductility and energy-dissipating property, thereby becomes the good structure of a kind of anti-seismic performance.In the super highrise building of high intensity Zone if adopt reinforced concrete structure, the ductility of total in fact not to reach the requirement of " big shake less than " again.
Compare with steel work, because the shaped steel external wrapping concrete has increased durability of structures and refractoriness, the initial adopted purpose of this also this just form of structure.Adopt steel reinforced concrete structure to save a large amount of steel, reduced cost, and overcome that steel work is antirust, anticorrosion, fireproof performance be relatively poor, needs shortcomings such as often maintenance.External wrapping concrete can prevent the cripling of steel member, has improved the integral rigidity of steel member, has significantly improved steel member out-of-plane torsional buckling performance, and steel strength is given full play to.In addition, the core concrete that is surrounded by the shaped steel frange plate is because of the effect of contraction of frange plate, and the concrete intensity of core space is improved.
Beam column shaped steel skeleton itself had constituted the structural system that rigidity is bigger when another advantage of the present invention was construction and installation, hang the skeleton of mould, sliding formwork when can be used as concreting, not only can save template in a large number supports, simplify the formwork engineering greatly, improved construction efficiency, the influence that makes work plane not supported by the beam column template can also be born working load.
The present invention is successfully applied in the engineering of National Indoor Stadium, the agent structure of this project has adopted steel reinforced concrete frame shear wall-steel support structure system, this structural system is the supporting system of sports palace large-span steel roofing, the antidetonation grade designs by special one-level, it is arranged in the sports palace periphery, with organic whole of the common composition of grandstand frame-shear wall structural system, adopt this structural system, solved structural seismic, fire prevention, cross section economy, series of technical such as easy to connect.Can improve on the one hand the anti-seismic performance of structure greatly, guarantee the safety of structure, can solve problems such as the connection that contains large span complex space structure and structure on the other hand again.
