Description
Technical field
The utility model belongs to staircase and girder design field, specifically relates to a kind of modularization truss without support staircase increased based on tilting section.
Background technology
Along with the fast development of staircase technical field, common staircase and girder can because the entirety of the change truss of staircase span changes, thus making truss interface, processing technology, moulds of industrial equipment etc. that a series of change occur, such truss cost is high, stability and reliability is poor and design complicated, moulds of industrial equipment are complicated, the production cycle is long, error rate is high.
Fig. 1 is the truss structure of the standard ladder that current Occupation coefficient is higher, mainly contains lower flat bed section (a), tilting section (b) and lower flat bed section (c) composition.When being applied to the larger occasion of span, such as, when being used on the public transport ladders such as overpass, subway, Railway station, need the height increasing tilting section (b), the scheme adopted at present as shown in Figure 2.
It is the design paper of the routine of tilting section rise of a truss 1650mm in Fig. 2.Flex point on the weld seam of flat bed section that in Fig. 2 to be the weld seam flex point of upper flat bed section: 1a be in 1a and 1d position, 1d is flex point under the weld seam of flat bed section, 1a and 1d place is higher to welding requirements, 1c and 1b is digonal link, mainly plays a supporting role.Due to the quality height of welding personnel in conventional design, when designer designs 1c with 1b two digonal links, design level height is different.Can design the digonal link of differing tilt angles, this has larger impact to the mechanical property of truss.Therefore the stability of truss can be more unreliable.In Fig. 2, flex point on the weld seam of lower flat bed section that to be the weld seam flex point of lower flat bed section: 1e be in 1e and 1h position, 1h is flex point under the weld seam of lower flat bed section, and these 2 higher to welding requirements, 1f and 1g is digonal link, mainly plays a supportive role.The same with upper flat bed in conventional design due to the quality height of welding personnel, when designer designs 1f with 1g two digonal links, design level height is different.Can design the digonal link of differing tilt angles, this has larger impact to the mechanical property of truss.Therefore the stability of truss can be more unreliable.
Owing to there is above-mentioned factors, after Truss Design completes, be not often inconsistent with on-the-spot size or stressed effect not good, cause needing again to design and produce truss, greatly increased the weight of the labour intensity of installation personnel, improve truss processing and cost of installation.Also there is no desirable processing scheme at present.
