Description

A kind of light-duty cable-stayed type scaffold

Technical field

The utility model relates to a kind of scaffold, is specifically related to that a kind of materials are economized, in light weight, the external scaffolding that makes things convenient for the workman to operate, can satisfy the fabric structure construction of various height and the requirement of decoration construction.

Background technology

At present, on construction market, obtain the widely used following several kinds of scaffolds that have: full hall scaffold, builder's jack, adhering lifting formula scaffold, protective frame.Wherein full hall scaffold shortcoming is that the consumption material is huge with manual work, labor strength is big, is eliminated gradually; And builder's jack and attachment type raise scaffold all only can the implementation part height protection; Such as, builder's jack generally is 4 to 6 floors, attached lift scaffold generally is 4 to 5 floors; Can not realize totally-enclosed construction to building; And its cost is high, and especially the attached lift scaffold construction cost is huge, has limited further developing of it.Protective frame is the product of the utility model inventor development, is used for the building main body construction stage, once sets up the 3-4 layer height, utilizes wall attaching parts to be fixed on the building, adopts tower crane to promote rising with the building main body operation that makes progress; Relatively before-mentioned products have simple in structure, processing ease, advantage with low cost.Its shortcoming is only to protect usefulness as major structure of construction, can not use as the exterior wall finishing scaffold, and it is applied and also receives big limitations.Several kinds of traditional scaffolds must efflux the high-altitude at scaffold and set up intersection rod members such as bridging for keeping stability in addition, and are abnormally dangerous during actual setting up.Labor strength is big.The inventor has researched and developed a series of light-duty cable-stayed type scaffold to this situation, and being characterized in adopting pull bar is main bearing member, diagonal member is set or tiltedly draws relief arrangement along the every floor of building; Changed the Path of Force Transfer of scaffold, given full play to the pull bar loading characteristic, bridging need be set; Reduced the danger of construction weight and workman operation, its result of use is fine, but on operability, also leaves some room for improvement; Such as, when tiltedly drawing relief arrangement to adopt screw thread etc. to regulate tension structure, its screw thread that exposes easily by cement mortar etc. pollute, corrosion; Nut can not normally be back-outed, and maintenance difficulties strengthens, and considers in the practical applications; Tiltedly draw the relief arrangement enormous amount, even nut can normally be back-outed, its workload is also quite big.

The utility model content

The technical problem that the utility model will solve provides a kind of light-duty cable-stayed type scaffold, and it tiltedly draws relief arrangement can realize auto-tensioning, is convenient to operation.

The utility model solves the technical scheme that its technical problem adopted: a kind of light-duty cable-stayed type scaffold; Comprise vertical member, transverse horizontal member, vertical equity member, holder; Scaffold floor and safety net; Vertical member is connected through fastener with the vertical equity member with the transverse horizontal member respectively, and scaffold floor is laid on the transverse horizontal member, and safety net is connected on vertical member or the vertical equity member; Described transverse horizontal member is pressed the certain level spacing and is distributed, and is arranged on each floor place; Said holder one end is connected with building, and the other end is connected with said transverse horizontal member; The node place that the transverse horizontal member is connected with vertical member connects tiltedly draws relief arrangement, and the holder of a floor is connected on tiltedly drawing the relief arrangement other end and being located at building; It is characterized in that: the said relief arrangement that tiltedly draws is that two ends are provided with the sealing ring set; An end closed collar wherein is inserted in the transverse horizontal member; Under the installment state, realize tiltedly drawing the auto-tensioning of relief arrangement through the connection fastener of move down said transverse horizontal member and vertical member.

The beneficial effect of the utility model is: because it is secondary to have cancelled the threaded adjusting that exposes; Eliminated the disadvantage that is easy to generate corrosion or pollution under the adverse circumstances at the construction field (site); The utility model is more convenient to operate, has improved operating efficiency greatly, has reduced the maintenance cost; And owing to component, the also corresponding reduction of manufacturing cost have been reduced.

Further, the structure of tiltedly drawing relief arrangement is confirmed, it is characterized in that: the described relief arrangement that tiltedly draws is a kind of of the drag-line processed of wire rope, loop chain bar, reinforcing bar, steel band or high strength fibre.

Further, the holder and the syndeton of sealing ring set are confirmed that it is characterized in that: said holder is provided with the connection stake that said sealing ring set is nested and closes.During use, directly the closed-loop cover is inserted in the connection stake, makes installation, dismounting become very easy.
