Description
Technical field
The utility model is related to construction engineering technical field, more particularly to a kind of segment frames beam of decile three.
Background technology
With continuing to develop for society, the high concentration of the continuous quickening, especially population of urbanization process, to limited
Huge digital population is accommodated in land area and brings very big pressure, and many high-rise or even high-rise building is then
Arise at the historic moment in this case；The problem of building of height solves per capita area, but increasing with floor,
Its stability turns into the most important thing of development.
The floor height of building basement floor determines by structure depth of beam, equipment pipe headroom, in general, equipment pipe
Road colleague is definite value at a high speed, and structural beams need certain altitude due to bearing requirements, and the key for reducing floor height is that structure height has
Effect utilizes equipment pipe headroom.Conventional uiform section Vierendeel girder can not utilize equipment pipe headroom, available at present
The Vierendeel girder form of equipment pipe headroom has two kinds of beam-ends haunched beam, holes in soffit uniform beam.The former utilizes equipment pipe
Road headroom carries out beam-ends haunch, and pipeline region in girder span is passed through, because its regulation internal force distribution capability is limited, it is impossible to effectively
Spaning middle section deck-molding is reduced, limited is reduced to floor height；The latter is using duct height as a structure deck-molding part, and deck-molding is increased, beam
Span centre region holes in soffit is walked for equipment pipe, but holes in soffit has strict position and size requirements, it is impossible to flexible arrangement,
Pipeline is walked and limits more, and it is very unfavorable to following pipeline modification.
Utility model content
The purpose of this utility model is to provide a kind of segment frames beam of decile three, can overcome existing haunched beam regulation internal force
Distribution capability is limited, holes in soffit uniform beam pipeline hole is unable to the deficiency of flexible arrangement.
Above-mentioned purpose of the present utility model technical scheme is that：A kind of segment frames beam of decile three,
Including Vierendeel girder body, Vierendeel girder body includes two sections of end carriages and one section of central sill, and end carriage is connected to the both sides of central sill and entirety is in
Inverted concave shape, the deck-molding of central sill be on the basis of deck-molding, the deck-molding of end carriage for central sill deck-molding oil (gas) filling device pipeline headroom it
With.
By using above-mentioned technical proposal, Vierendeel girder form internal force, which is distributed in deck-molding distribution, tends to be reasonable, its component itself
Possess economic rationality, meanwhile, compare beam-ends haunched beam, its adjust internal force distribution capability it is stronger, can more effectively reduce across
Middle section deck-molding, compared to holes in soffit uniform beam, its span centre region provides sufficient space for flexible arrangement pipeline, to working as
Preceding pipeline is arranged and expected future pipeline modification is highly beneficial.For basement structure, the Vierendeel girder form possesses itself
Economy, reasonability, while lower room story height can be effectively reduced, reduce foundation ditch and dig depth and construction timber amount.
It is preferred that, middle depth of beam is the 1/18 ~ 1/22 of Vierendeel girder body span.
By using above-mentioned technical proposal, because central sill is wide enough, equipment pipe can freely be arranged in the region, two ends
Increase beam using equipment pipe headroom, change Stiffness Distribution in girder span, be distributed while also changing internal force in girder span.Phase
Compared with uniform beam form, the beam end support moment of flexure increase 25% ~ 30% of three sections of beam forms of decile, mid span moment reduces 25% ~ 30%,
Mid span moment is reduced, and is effectively reduced spaning middle section deck-molding, and support moment increase is undertaken by the section of increasing deck-molding.Therefore, etc.
Point three segment frames beam forms meet equipment pipe pass through demand while also possess economy, reasonability.
It is preferred that, provided with the end stirrup being distributed along its length in end carriage, it is provided with and is distributed along its length in central sill
Middle stirrup.
By using above-mentioned technical proposal, equally distributed stirrup is set respectively in end carriage and in central sill so that decile three
Segment frames beam possesses uniform load-bearing capacity and higher structural stability.
It is preferred that, end stirrup is included positioned at the end hoop reinforcement and the middle conventional stirrup area in end at two ends, middle stirrup bag
Include positioned at the middle hoop reinforcement and middle middle conventional stirrup area at two ends.
By using above-mentioned technical proposal, hoop reinforcement is set respectively at the two ends at the two ends of end carriage and central sill, improved
Bearing capacity and structural strength at this, the possibility of reduction Vierendeel girder fracture.
It is preferred that, Vierendeel girder body is provided with the elongated muscle of back and beam bottom muscle, and the elongated muscle of back is located at top and through framework
Beam body, the beam bottom muscle that beam bottom muscle is located at bottom and central sill is anchored into end carriage.
By using above-mentioned technical proposal, the structure in the elongated muscle of back and beam bottom muscle raising Vierendeel girder body length direction connects
Continuous property and uniform structural strength, reduce stress concentration.
It is preferred that, the beam bottom muscle quantity at end carriage is two rows, and upper row extends end carriage end and blocked, and bottom drains into end carriage end and upper curved
Extend back.
By using above-mentioned technical proposal, end carriage plays the important function for sharing moment of flexure, therefore the structural strength of end carriage will
Ask higher than central sill.
It is preferred that, the intersection of end carriage and central sill is provided with end additional hooping and middle additional hooping, and end additional hooping is located at end
In beam, middle additional hooping is located in central sill.
By using above-mentioned technical proposal, end carriage and central sill intersection cross-sectional sizes change, to reduce variable cross-section pair
The influence that Vierendeel girder structural strength in this place and dimensional stability are caused, sets additional hooping, improves the structural strength at this
And stability.
To sum up, the segment frames beam of a kind of decile three described in the utility model, simple in construction, bearing capacity is strong；Internal force is distributed
It is reasonably distributed with deck-molding, can be with flexible arrangement equipment pipe；Lower room story height can be effectively reduced simultaneously, reduced foundation ditch and dug
Depth and construction timber amount.
