Description
Technical field
This utility model is a kind of anti-continuous collapse transfer framework structure, belongs to the renovation technique of anti-continuous collapse transfer framework structure.
Background technology
Building structure as occurred continuous collapse to will result in great casualties and property loss, is the biggest threat to safety under suffering accidental action (such as local impact, explosion wave etc.).The safety of building structure is had conclusive impact, force path and component arrangement to determine the anti-continuous collapse performance of organization plan by organization plan.
National regulation continuous collapse anti-to building structure design at present not yet has clear and definite and concrete requirement, and designer does not typically consider in the design.Structure that is discontinuous due to structure vertical member and that cause is changed, relatively conventional in building structure. and bottom transformational structure uses frame structure more, and transfer framework has conclusive impact to the safety of structure.At present the transformational structure in design is usually unidirectional conversion, and in the short direction of structure based on single span or twin spans, as single span transfer framework, when a transition mast occurs to destroy, overall structure is almost certain to continuous collapse.This makes the unidirectional transfer framework structure of single span or twin spans have fatefulue weakness in anti-continuous collapse ability.
Summary of the invention
The purpose of this utility model is to consider the problems referred to above and provide the anti-continuous collapse transfer framework structure of a kind of progressive collapse-resisting ability strengthening transfer framework structure.This utility model is reasonable in design, convenient and practical.
The technical solution of the utility model is: anti-continuous collapse transfer framework structure of the present utility model, includes transition mast, conversion beam, upper box trestle, and the most some conversion beams are bearing on transition mast, and upper box trestle is installed on conversion beam.
This utility model compared with prior art, has the advantages that
1) this utility model conversion plan is the two-way space structure system with High redundancy, when overall structure is destroyed under local transitions post meets with accidental action, possesses the strongest anti-continuous collapse ability；
2) this utility model conversion span can more existing conventional scheme appropriateness increase.
3) during the transfer framework that general single span is a unidirectional post destruction wherein, structure collapses, and this utility model uses bi-directional conversion system can avoid continuous collapse；Conversion span can increase by more than 20% under the conditions of identical deck-molding.
This utility model is that a kind of design is ingenious, function admirable, convenient and practical anti-continuous collapse transfer framework structure.

Detailed description of the invention
Embodiment:
Structural representation of the present utility model is as shown in Figure 1, 2, 3, anti-continuous collapse transfer framework structure of the present utility model, including transition mast 1, conversion beam 2, upper box trestle 3, the most some conversion beams 2 are bearing on transition mast 1, and upper box trestle 3 is installed on conversion beam 2.
In the present embodiment, above-mentioned upper box trestle 3 is that multilamellar or high level are by transfer framework or shear wall structure.
In the present embodiment, above-mentioned transition mast 1 includes some Y-direction transition masts 11 and some X to transition mast 12.Some Y-direction transition masts 11 are distributed along Y-direction, some X to transition mast 12 along X to distribution.
In the present embodiment, above-mentioned conversion beam 2 includes Y-direction conversion beam 21 and X and is rigidly attached to Y-direction transition mast 11 and X to the upper end of transition mast 12 to conversion beam 22, Y-direction conversion beam 21 and X to conversion beam 22.
In the present embodiment, the post of the some Y-direction transition masts 11 in above-mentioned transition mast 1 is away from for 7 to 20 meters, and some X are to the post of transition mast 12 away from for 7 to 20 meters, and some Y-direction transition masts 11 and some X are single span or twin spans structure to transition mast 12.
In the present embodiment, above-mentioned transition mast 1, conversion beam 2 use cast-in-situ reinforced concrete column or combined steel and concrete column also or steel structure column.
In the present embodiment, above-mentioned transfer framework structure uses cross or the horizontal layout of groined type.
In the present embodiment, construction is built order and is: in advance construction builds Y-direction transition mast 11 and X to transition mast 12, then Y-direction conversion beam 21 and X of constructing is to conversion beam 22, finally construction upper box trestle 3 or shear wall.When transition mast and conversion beam are as used armored concrete or steel reinforced concrete material, must can form removal when concrete arrives normal intensity more than 80%.
In the present embodiment, above-mentioned transfer framework structure, use cross or the horizontal layout of groined type.Cross or groined type are generally orthogonal system, it is possible to appropriateness corner, no more than 15 °.
This utility model relates to a kind of two-way (cross or groined type) transfer framework structure, and its span is typically between 7 meters to 20 meters.Frame beam column can be ordinary reinforced concrete structure or steel reinforced concrete structure or steel construction or a combination thereof.
This utility model is a kind of transfer framework structure, uses cross or the horizontal layout of groined type.Cross or groined type are generally orthogonal system, it is possible to appropriateness corner, no more than 15 °.The transfer framework of structure bottom is made up of with conversion beam transition mast, and transfer framework superstructure is that multilamellar or high level are by transfer framework or shear wall structure.Transform frame trestle away from generally 7 to 20 meters, usually single span or twin spans structure.Transition mast, conversion beam component pattern can use common cast-in-situ reinforced concrete column or combined steel and concrete column also or steel structure column, and transition mast uses with conversion beam and just connects in succession.Order is built in construction: transition mast, then conversion beam of constructing are built in construction in advance, the frame column or shear wall changed of finally constructing.When transition mast and conversion beam are as used armored concrete or steel reinforced concrete material, must can form removal when concrete arrives normal intensity more than 80%.
