Abstract
The invention discloses a super long span without supporting truss walking board which comprises a platform main beam, a support beam and an end vertical frame, the support beam is arranged on the platform beam, the end vertical frame is arranged on the both ends of the platform main beam. the super long span without supporting truss walking board satisfies the using requirement through the reasonable design in the condition of no support in the special area, And using finite element strength analysis software for strength and stability checking, from the perspective of computing providing basis, the device can satisfy more than 15 m span no support to walk, And in the design of the same type of platform, the weight is the lightest, the requirement of the Marine weight control is satisfied.
Description
Technical field
Walked on stage without sub-truss formula the present invention relates to a kind of overlength span.
Background technology
In the prior art, in extra large work project, some special areas need to design overlength span（Length reach 15 meters with
On）Walk on stage, it is current etc. for maintenance of equipment or personnel, but the problems such as due to equipment arrangement or surrounding structure form, lead
Causing the lower section of walking on stage cannot set inclined support structure, this to walk on stage because span is oversize according to structural mechanics single beam design principle
And centre cannot effectively support, it is not enough that tie point intensity easily occurs, situations such as deform excessive or unstability.
The content of the invention
Can meet the requirement that more than 15 meters spans are walked on stage without support it is an object of the invention to provide a kind of, and in same type
Weight is most light in the design walked on stage, and the overlength span for meeting the requirement of extra large work Weight control is walked on stage without sub-truss formula.
The technical scheme that is used to achieve the above object of the present invention is：A kind of overlength span is walked on stage without sub-truss formula,
Including platform girder, support beam and end vertical frame, the support beam is arranged on platform girder, and the end vertical frame is installed
At platform girder two ends.
The platform girder is provided with guardrail of walking on stage.
The support beam is triangular truss structure.
The platform girder, support beam and end vertical frame are constituted by pipe.
A kind of overlength span of the present invention is walked on stage without sub-truss formula, in the case of special area is unsupported, by reasonable
Design it is met use requirement, and strength and stability check is carried out using finite Element Intensity Analysis software, from calculating angle
Degree provides foundation, can meet the requirement that more than 15 meters spans are walked on stage without support, and the weight in the design that same type is walked on stage
It is most light, meet the requirement of extra large work Weight control.

Specific embodiment
As shown in Figures 1 to 6, overlength span is walked on stage without sub-truss formula, including platform girder 1, support beam 2 and end are hung down
Straight frame 3, support beam 2 is arranged on platform girder 1, and end vertical frame 3 is arranged on the two ends of platform girder 1, and platform girder 1 is provided with
Walk on stage guardrail 4, support beam is triangular truss structure, because span is larger, maximum stress of walking on stage occurs at two ends, it is therefore desirable to
It is fixed in strength supporting construction, such as nearby without strong structure, it is necessary to increase the fixed beam being connected with strong structure, as illustrated,
Two ends are connected using the vertical I-beams of 9.5x150+12.5x100 as end, and truss girder stage casing is Φ 114x16 pipes, by
Larger in end stress, two ends increase thick to Φ 140x20, it is ensured that end intensity meets calculating and requires, Φ 45x4 are used between girder
Grid and railing can be increased as the triangular form truss support between girder, on platform with the pipe of Φ 114x8 current for personnel
Use, the uniform load of related outfititem weight and code requirement is the Main Load of this platform, while needing to consider periphery
The environmental factors such as wind load, strength and stability requirement is met through FEM calculation, according to material geometrical property, circle under equivalent weight
The bending resistance of pipe is most strong, so this is walked on stage, all material is constituted using yield strength tubing higher without exception, using geometry
Upper most stable of gusseted principle, the Cross section Design of platform is del, and three girders run through both sides, and centre is using in the same direction
Batter brace pipe, making to overcome may be delivered to girder, the calculating according to structure to single beam, the girder pipe larger to stress
Two ends are strengthened, with the result of calculation of finite element analysis software as foundation, it is ensured that strengthened girder meets intensity requirement,
The design of the platform can meet more than 15 meters spans without the requirement walked on stage of support, and weight is most in the design that same type is walked on stage
Gently, the requirement of extra large work Weight control is met.
