Description
Technical field
The utility model relates to the overhanging type steel scaffold in a kind of highrise building, particularly a kind of the shaped steel suspension scaffolding structure.
Background technology
Along with present habitat condition raising and perception demand, facade moulding evagination and plane corner increase increasingly.For this reason, being widely used of the shaped steel suspension scaffolding, has become general high-building construction protection and ornamental external scaffolding main flow at present.
In existing shaped steel Overhanging Outside Scaffold, cantilever steel girder is all by Ω shape reinforcing bar draw ring or U-shaped anchor bolt, directly be embedded in floor structure concrete beam, position, plate bottom layer of the reinforcing steel face, fix with iron wire and reinforcing bar binding, easily be subjected to displacement in concrete placings, for meeting anchoring requirement, bottom needs two additional bars setting up vertical anchor to make beading, after cantilever steel girder is removed, reinforcing bar draw ring or anchor bolt all excise with gas cutting, anchor self and additional muscle thereof can only use once, cause material serious waste, especially Ω shape reinforcing bar anchor and cantilever steel girder are fixed and are only adopted timber wedge to hold out against, be out of shape large and cannot horizontal thrust be born.Simultaneously, existing cantilever steel girder controls to stretch into building structure canned paragraph length, the overhanging section of encorbelmenting termination should hang, and (also can not establish) makes safety stock, selects the flexible wire ropes not needing to calculate, can have a strong impact on highrise building shaped steel Overhanging Outside Scaffold in situations and build smoothly.
1. when the architectural image section of encorbelmenting requires longer dimension, large length large gauge shaped steel of satisfying the demand, construction carrying and installing space plane restricted, cannot build;
2. adopt regular size and shaped steel outrigger made by the 16# i iron being beneficial to constructing operation, when canned paragraph length, girder steel intensity and monolithic stability are all satisfied, and termination amount of deflection is not when meeting, need to adopt large model i iron, cause construction difficult and also waste material;
3., when adopting same canned paragraph to require that length lays anchor point at floor face, the some pull-up simultaneously of same strip can be formed, fragile floor slab structure;
4. when building structure frame bears many cantilever steel girder dead-end pressures, often can cause Lack of support, need to increase additional bar or increase frame beam section size.
Summary of the invention
The purpose of this utility model provides a kind of the shaped steel suspension scaffolding structure to solve above-mentioned the deficiencies in the prior art.
To achieve these goals, a kind of the shaped steel suspension scaffolding structure designed by the utility model, comprise and be preset in steel I-beam of encorbelmenting and install novel anchor on floor, be fixed on this steel I-beam of encorbelmenting by this novel anchor and install steel I-beam of encorbelmenting on floor, one end is connected with the end of encorbelmenting of steel I-beam of encorbelmenting, the other end to be fixed on superstructure structure floor and to establish prestressed pre-stretching wire rope, and by the steel pipe scaffold that standard is set up, described novel anchor is primarily of one piece of angle steel pressing plate, one block of positioning of bottom steel plate and add for a pair plastic bushing bolt composition, described positioning of bottom Interal fixation is installed in the template that floor builds in concrete below reinforcing bar at steel I-beam of encorbelmenting, wherein said positioning of bottom steel plate is arranged in steel I-beam of encorbelmenting and installs the below that concrete reinforcing bar built by floor, and install floor by establishing aperture iron nail with steel I-beam of encorbelmenting to build concrete Template Location and fix, add the melting welding of holing of the bottom of plastic bushing bolt and positioning of bottom steel plate for a pair to fix, its top section double nut is installed floor fixed by will encorbelment steel I-beam and steel I-beam of encorbelmenting of angle steel pressing plate, the length adding thread segment on plastic bushing bolt meets to add after double nut is locked stays three to buckle, namely 3 screw threads to also be exposed after tightening double nut on thread segment, the general length of 3 screw threads is about 5 ㎜, described steel I-beam of encorbelmenting also is welded with thrust piece, the mutual apical grafting of lateral surface of this thrust piece and angle steel pressing plate.
Above-mentioned a kind of the shaped steel suspension scaffolding structure, after floor structure formwork completes, by the positioning of bottom Interal fixation in above-mentioned in template, then assembling reinforcement on it, build concrete, lay after reaching sufficient intensity and encorbelment steel I-beam and add angle steel pressing plate, with double nut tighten put in place fixing.After outrigger of encorbelmenting is removed, first unload double nut from adding plastic bushing bolt, then angle steel pressing plate is added plastic bushing bolt from a pair to take off, finally touch with gavel and add plastic bushing bolt top, take off novel anchor, and unit assembled window, repeatedly reusable after cleaning, maintenance, because positioning of bottom steel plate is placed at the bottom of the steel mesh reinforcement of floor structure, therefore additional muscle need not be set up.Meanwhile, anchor and template are fixed, and can guarantee structure reinforcing bars topping, have accurate positioning, stressed reliable, save reinforcing bar and guarantee the feature of quality.And, above-mentioned superstructure structure floor is fixed with suspension ring, described wire rope one end is fixed on the end of encorbelmenting of steel I-beam of encorbelmenting, and its other end runs through suspension ring and carries out pre-stretch-draw, is locked after setting up setting value prestressing force by rope clamp, prestressed wire rope is set up with pre-method for stretching, participation is encorbelmented steel I-beam cooperative bearing, improves outrigger bearing capacity, deformation rigidity, is beneficial to constructing operation, and the load of floor edge supporting beam can be reduced, economize on material.Simultaneously when oblique pull wire rope produces an inside thrust to steel I-beam of encorbelmenting, in order to prevent the inside slippage of steel I-beam of encorbelmenting, above-mentioned steel I-beam of encorbelmenting is welded with thrust piece, the briquetting lateral surface of this thrust piece and novel anchor holds out against mutually, thus can effectively avoid encorbelmenting steel I-beam appearance to intrinsic displacement.
The utility model easy accessibility, guarantees wire rope and encorbelments steel I-beam cooperative bearing, greatly increasing encorbelment steel I-beam bearing capacity, deformation rigidity, improve degree of safety with under condition, saving material; Solve comparatively large cantilever, corner and other complicated position and use a builder's jack difficult problem, there is better Social and economic benef@.
