Description

Lay particular stress on heart heavy wall ultra-large type reinforced concrete structure stencil-type steel supporting system
(1) technical field
The utility model relates to a kind of support system of concrete structures template.
(2) background technology
Along with commercial production scale rapidly to the development of maximization direction, the concrete structures volume of each link is also increasing in the production procedure, shape becomes increasingly complex.The concrete funneled bin is used for the exit of industrial structure feed bin more.The plane cross section of feed bin can be divided into circle, square, rectangle substantially; The outlet of feed bin is divided into several types such as single port, twoport, four-hole.Most concrete feed bins all are center of gravity and material outlet center axis bilateral symmetry that overlap or material outlet.The wall thickness of feed bin is in 250mm.And it is different with common feed bin to lay particular stress on heart heavy wall ultra-large type steel concrete feed bin, and its outlet is eccentric, and bulkhead is thick and heavy, and volume is tall and big, and whole feed bin does not have pillar.The full feed bin joist suitable for reading that leans on is connected with the top bulkhead.And be the structure feed bin that many storehouses are arranged continuously.This feed bin section is irregular rectangle, and not to old, the angle of inclination, four inclined-planes of feed bin is all different, and differs bigger on two axis in length and breadth on the horizontal plane for the feed bin upper and lower opening.
The formwork bracing system of laying particular stress on heart heavy wall ultra-large type steel concrete funneled bin is for construction quality, and the especially consideration of construction safety always is a construction Difficulties.As traditional wooden construction support system, because material is too wasted and is eliminated, what application was wider at present is the support of fastener type steel pipe scaffold to the feed bin template system.Application as fastener type steel pipe scaffold in the general civilian construction has outstanding advantage: i.e. its flexibility, this outstanding advantage is at the industrial construction with special form and complicated construction condition, sometimes will become fatal weakness, exactly because the flexibility of mould bases support system, make and lay particular stress on heart ultra-large type funneled bin fastener type steel pipe scaffold mould bases support system in concreting process, because its position of centre of gravity constantly changes the generation lateral thrust and cave-in accident very easily takes place.
(3) utility model content
The purpose of this utility model provides a kind of heart heavy wall ultra-large type reinforced concrete structure stencil-type steel supporting system of laying particular stress on, and solve the firm support problem that lays particular stress on heart heavy wall ultra-large type reinforced concrete structure template; And solution conventional art materials are many, cost is high, job practices complexity, technical problem of poor safety.
For achieving the above object, the utility model adopts following technical scheme:
This heart heavy wall ultra-large type reinforced concrete structure stencil-type steel supporting system of laying particular stress on, comprise scaffold and be supported on rack platform below the template, above-mentioned template comprises soffit formwork, upright template and inclination template, it is characterized in that: above-mentioned rack platform is by lower floor's steelframe platform, middle level steelframe platform, upper strata steelframe platform is formed the multi-layered type steel supporting system, every layer of steelframe platform is formed by connecting by steel pipe post and section steel beam, on the steelframe platform of upper strata, be positioned at the inclination template below be connected with local little vertical steel body panel, between inclination template and local little vertical steel body panel and upper strata steelframe platform, be connected angle ejector rod.
Above-mentioned lower floor steelframe platform is supported on the concrete floor, is supported by the steel pipe jacking between concrete floor and the ground, below.
Can be connected with shaped steel diagonal brace or bridging between the above-mentioned adjacent steel body panel.
Can be connected with shaped steel diagonal brace and bridging between the above-mentioned adjacent steel body panel.
Above-mentioned section steel beam can be steel I-beam or steel channel beam.
Above-mentioned scaffold can be to the double-pole scaffold at structure top from ground.
Compared with prior art the utlity model has and save materials, cost is low, job practices is simple, the characteristics that safety is good are that example has following some beneficial effect with the steel concrete funneled bin:
1, the formwork bracing system of feed bin all adopts steel pipe and formed steel construction.Compare with steel concrete funneled bin wooden construction support system, the material yield rate utilization rate height of shaped steel support system, the utilization rate again of material can reach more than 95%, and the recycling rate of wooden construction support system material is almost nil.
2, replace scaffold to make backing material with big section profiled bar, reduced material usage, reduced the lease expenses of turnover material tool on the one hand, on the other hand because the minimizing of working measure materials has also reduced labour cost simultaneously.
3, bracing frame adopts steel work to be convenient to connect and dismounting all recyclings of the material overwhelming majority.Replace carpenter and scaffolder to finish the construction of steelframe support system with the steel work workman, labour's distribution changes, and the support system construction becomes the multiplex (MUX) and plants continuous productive process, has accelerated the construction speed that support system is installed and removed.The utility model uses shaped steel to make supporting steel frame, compares with using scaffold tube, obviously reduces when doing owing to material, has then accelerated construction speed, has guaranteed the construction period.
4, steel work bracing frame good integrity, supporting ﹠ stablizing have enough intensity.Shaped steel on the bottom steelframe platform is as the steelframe that shifts load.The load of feed bin and bracing frame passes to by these shaped steel on the primary and secondary concrete beam of platform, passes to ground by concrete beam lower supporting rod steel pipe again.Load Transfer to the primary and secondary beam of bottom steelframe platform, realized with bottom steelframe platform with the feed bin load transfer then by the upper strata steelframe in the upper strata.
5, steel bracket increases vertical support, and good integrity is all welded in the steel bracket crosspoint.
6, the utility model also helps protection concrete structures and template, improves construction safety and construction quality level, and the assurance engineering is normally carried out.Each layer supports and constitutes an integral body, and feed bin weight is reached bottom steelframe platform girder, by the section steel reinforcement platform power reached the concrete platform beam, reaches ground by the lower support steel column again by support system, has effectively protected top reinforcement concrete platform structure.
7, through measuring and calculating, the utility model is saved working measure expense nearly 30% than using scaffold tube to do support system.Can be used for various templates supports of laying particular stress on heart heavy wall ultra-large type reinforced concrete structure such as large-scale step funneled bin.
