Abstract
The utility model discloses a bolt-fixed type oblique-pulling cantilever scaffold, which comprises a plurality of cantilever shaped steel beams, a steel bar pull rod, section steel and a scaffold body, wherein the roots of the cantilever shaped steel beams are fixed on boundary beams of a main structure of a building, and the cantilever shaped steel beams are arranged in parallel; the end part of the cantilever type steel beam is connected with one end of a steel bar pull rod, the steel bar pull rod is in a diagonal pulling shape, and the other end of the steel bar pull rod is also fixed on the boundary beam of the main structure of the building through two high-strength bolts; the cantilever steel beams are horizontally connected by profile steel connecting beams; and a frame body outside the cantilever is erected on the section steel. The utility model discloses to prior art's not enough, adopt the shaped steel root of encorbelmenting to fix on the structure boundary beam with high strength bolt, hang a structure that draws to one side on the tip reuse reinforcing bar pull rod, the narrow and small difficulty in construction space is solved to this structure, material saving, and preparation, installation and dismantlement are convenient, safe and reliable.
Description
Technical field
The utility model relates to a kind of scaffold, specifically is that a kind of bolt fastening tiltedly draws builder's jack.
Background technology
Along with increasing of domestic building construction high level and little high-level structure, the utilization widely in building operations of shaped steel builder's jack.The structural form of the shaped steel overhanging scaffold that generally adopts is divided into outstanding cable-stayed type and following diagonal-bracing type at present.Wherein, upward outstanding cable-stayed type is to add wire rope inclined-pulling in the shaped steel outrigger end of being stretched out by structure; Or on floor the embedded bar ring, overhanging crossbeam inserts in the ring, sets up shelf on the transverse horizontal member, and then the outside support body of encorbelmenting.The shaped steel that this method needs is more, need stay the finishing of establishing than exterior wall after the hole is not easy to greatly at the position of shear wall and post, and owing to shaped steel length very, remove inconvenience, easily causes danger.Following diagonal-bracing type builder's jack is to add a bearing diagonal below shaped steel outrigger end.From the used material of shaped steel builder's jack, making, peace tear open, aspect analysis such as recruitment situation, upward outstanding cable-stayed type effect is better than declivity support formula, but goes up outstanding cable-stayed type in use not as diagonal-bracing type is convenient down.
The utility model content
Technical problem to be solved in the utility model provide a kind of can be under the narrow and small situation of construction space normal use tiltedly draw builder's jack, this scaffold economical with materials, making, installation and convenient disassembly, safe and reliable.
Bolt fastening described in the utility model tiltedly draws builder's jack, it comprises some section steel beams of encorbelmenting, steel bar rod, shaped steel and support body, the described section steel beam root of encorbelmenting is fixed on the constructure body structure side bar by two high-strength bolts, the parallel installation of section steel beam of respectively encorbelmenting; The encorbelment end of section steel beam is connected with steel bar rod one end, and steel bar rod is and tiltedly draws shape, and the steel bar rod other end also is fixed on the constructure body structure side bar by two high-strength bolts; Respectively encorbelment and connect with shaped steel coupling beam level between section steel beam; Set up the outside support body of encorbelmenting above the shaped steel.
Above-mentioned steel bar rod can be divided into two sections, connects by flower basket bolt between two sections.
The utility model guarantees monolithic stability and intensity by to existing agent structure bearing capacity, high-strength bolt intensity, fusion length, the power checking computations of preformed hole place concrete partial pressing, effectively satisfies the designing requirement of support body.Carry out the preloading test at the scene, form firm, stable, a safe system of encorbelmenting.The utility model adopts the shaped steel root of encorbelmenting to be fixed on the structure side bar with high-strength bolt at the deficiencies in the prior art, and the end is again with the outstanding scaffolding structure that tiltedly draws on the steel bar rod, this structure solves the narrow and small difficulty of construction space, economical with materials, making, installation and convenient disassembly, safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, bolt fastening of the present utility model tiltedly draws builder's jack, comprise the some section steel beams 1 of encorbelmenting, steel bar rod 2, shaped steel 3 and support bodys, described section steel beam 1 root of encorbelmenting is fixed on the constructure body structure side bar 4 by two high-strength bolts 6, the section steel beam 1 parallel installation of respectively encorbelmenting; The encorbelment end of section steel beam 1 is connected with steel bar rod 2 one ends, and steel bar rod 2 is and tiltedly draws shape, and steel bar rod 2 other ends also are fixed on the constructure body structure side bar, and steel bar rod 2 is divided into two sections, connects by flower basket bolt 5 between two sections.Respectively encorbelmenting, 1 usefulness shaped steel, 3 coupling beam levels connect between section steel beam; Set up the outside support body of encorbelmenting above the shaped steel 3.
Characteristics of the present utility model:
1, safe and reliable:
Upper outstanding cable-stayed type shaped steel outrigger scaffold adopts steel wire rope to connect to soft drawn connects as oblique pull, and the overhanging type steel beam generally need pass in the external wall embedding structure concrete, destroys easily external wall structure, causes infiltration hidden danger. The utility model adopts at existing structure side bar place preformed hole, be connected with overhanging type steel with high-strength bolt, the overhanging type steel beam is as the load-carrying member of overhanging scaffold, oblique pull connects and adopts reinforcing bar to socket, and with the level trough steel overhanging type steel is coupled together and to strengthen stability, guarantee the safety of this scaffold in construction.
2, overcome the narrow and small difficulty of construction space, easy installation and removal:
Former strut-framed suspension scaffold needs to make the trigonometric expression builder's jack as support in overhanging type steel beam lower end, palpus lot of materials, manpower, installation inconvenience, and the construction site is narrow and small. The utility model compares with the former system of encorbelmenting that only section steel beam is as load-carrying member, and high-strength bolt passes in the preformed hole, and both sides are twisted solid with nut, and the end adds outstanding oblique pull on the reinforcing bar, and the below construction surface of the whole support body of encorbelmenting is free from worry, construction, installs with removing all and makes things convenient for.
3, economical with materials:
The former outstanding shaped steel of strut-framed shaped steel outrigger scaffold that tiltedly draws must stretch into 2/3 length in the existing agent structure, this be by on the structural mechanics outer encorbelment stretch into fixed end must not be less than 1: 2 requirement, compare with the erection method that the utility model adopts 2 high-strength bolts to be connected with shaped steel, many with steel, manually measure and have over halfly, and various material accessory is reusable.Reach the effect of material-saving environmental protection.
4, applicability is strong:
Former outstandingly must be repaired structure outer body hole to be provided after tiltedly drawing the dismounting of strut-framed shaped steel outrigger scaffold, easily cause infiltration hidden danger, and the utility model is at dismounting side bar high-strength bolt fixedly behind the shaped steel builder's jack, only side bar preformed hole place is filled up, must reduce influence to the problem of exterior wall box out repairing after having solved the builder's jack dismounting to indoor and outdoor decoration.
