Description

A kind of overhanging type steel support for shuttering for suspended structure at high altitude
Technical field
The utility model belongs to building engineering field, particularly relates to a kind of overhanging type steel support for shuttering for suspended structure at high altitude.
Background technology
For urban skyscraper, traditional pin hand cradle, the method of the steel pipe scaffold namely upwards set up from ground shown set up take a lot of work, the construction period is long, unsafe drawback of constructing, therefore, overhanging scaffold for middle-high building arises at the historic moment, and wherein the shaped steel suspension scaffolding is one of main scaffold type.
The shaped steel suspension scaffolding generally arranges overhanging component and by a kind of scaffold of overhanging component upper load from building storey.It has not by the advantage that building height affects.The key of overhanging scaffold is that intensity, rigidity and stability must meet related request, and has reliable connection with building structure, the load of scaffold can be passed to building structure safely.The shaped steel suspension scaffolding is also a kind of cantilevered structure that present engineering is often used.It is worth mentioning that the application of constructor for overhanging component is often by experience in the past, for the concrete stress performance of overhanging component, the selection of component etc. the concept that all neither one is clear and definite, and neither be a lot of to the regulation of overhanging component in specification.So existing builder's jack platform all to there is structure power transmission indefinite, bonding strength is not high, the defect that safety is lower.
Summary of the invention
In order to solve the problem, the utility model provides a kind of overhanging type steel support for shuttering for suspended structure at high altitude, reaches and is convenient to mounting or dismounting and the reusable object of energy.
Adopt following technical scheme: a kind of overhanging type steel support for shuttering for suspended structure at high altitude for this reason, comprise the overhanging type steel beam of cross section in " work " type, concrete structure, support for shuttering and template, concrete structure vertically compresses with the bottom of overhanging type steel beam and coordinates, overhanging type steel beam is provided with support for shuttering, is equipped with template between support for shuttering; It is characterized in that: in concrete component, be also provided with the pre-buried U-bolt in concrete component in a lower end, described U-bolt horizontal width matches with overhanging type steel beam width, U-bolt is vertically highly not less than overhanging type steel cantilever thickness and pre-buried thickness sum; Also comprise a pressing plate, pressing plate is provided with screwed hole, the vertical top of U-bolt through a pressing plate screwed hole after respectively with a nut lock stressed joint, described pressing plate vertically compresses with the top of overhanging type steel beam and coordinates; Described overhanging type steel beam is provided with mounting head, is provided with support for shuttering by mounting head.
Further, described U-bolt two ends arrange the silk mouth that length is not less than 50mm.
Further, be provided with fixture between the space, horizontal both sides of the overhanging type steel beam of described " work " font, described fixture is timber wedge.
Further, pad between the bottom of described overhanging type steel beam and concrete structure and be provided with backing plate.
Further, fixing reinforcing bar is embedded with inside the turning bottom described U-bolt.
Further, the pre-buried draw ring of last layer of described overhanging type steel beam, described draw ring holds overhanging type steel beam by wire rope; Or the support bar of a diagonal brace reinforcing is provided with at the lower one deck installing overhanging type steel beam.
Further, described support for shuttering adopts steel pipe to set up, and described support for shuttering surrounding hangs close order safety net.
Pass through such scheme, make full use of original structure condition and shaped steel self-bearing capacity, under high-altitude overhanging component, one deck installs overhanging type steel beam according to the mode of outrigger of encorbelmenting, and overhanging type steel beam is set up steel tube frame, installation form, construction high-altitude overhanging reinforced concrete structure.After superstructure intensity reaches requirement, more progressively remove support for shuttering and overhanging type steel beam.If top also has cantilevered structure, then recycle; Or directly utilize this layer of overhanging type steel beam as the girder of outrigger of encorbelmenting.
This programme has the following advantages: the bearing capacity 1, making full use of shaped steel self, and high-supported formwork frame is converted into general support for shuttering, decreases a large amount of inputs of steel pipe scaffold, has saved labour; 2, overhanging type steel support for shuttering is clearly stressed, dependable performance, and technique is simple, and architecture quality can be protected; 3, overhanging type steel support for shuttering comparatively high-supported formwork frame height reduction, reduces security risk, accelerating construction progress; 4, the shaped steel of cantilevered formwork can be used as builder's jack Cantilever Beams, if a building has repeatedly encorbelments, and under meeting related request prerequisite, also can repeatedly use, economical rationality.
For load larger lay particular stress on, partially long cantilevered structure only utilizes shaped steel self bearing capacity not meet the demands, this programme provides two kinds of corresponding reinforcement measures, namely fix by steel cable draw ring or with support bar diagonal brace, construction safety can be ensured, effectively increase the bearing capacity of overhanging type steel, to meet construction requirement.
