Abstract
The utility model provides a supporting system for a large-span assembly type cantilevered scaffold. The supporting system comprises trusses, a supporting pin, a diagonal brace, and a wall adapter, wherein both ends of each truss are provided with connectors, through which the trusses can be connected to obtain a required length, and the supporting pin, the diagonal brace, and a wall form a triangular fixed frame. The length of the diagonal brace can be adjusted so that the supporting pin is at a level position. The connected trusses are arranged on the supporting pin which has a truss support arranged thereon. The truss support can be sleeved at any position on a lower chord member of the trusses. If the contact part between the trusses and the supporting pin is not on a fulcrum, a truss support is arranged at the contact part to increase the bearing force of the contact part between the trusses and the supporting pin, preferably each supporting pin being provided with one truss support. The trusses are produced in a factory, conveyed to a building site, connected to a required length and arranged on the supporting pin. The distance (within 12m) between supporting pins can be adjusted according to the position of a structural framework column or a shear wall pier. The erecting speed is rapid, and the length of the diagonal brace can be adjusted, so that the diagonal brace may not be influenced by the flatness of the vertical wall. The supporting system is practical and worthy of promotion.
Description
Technical field
The utility model relates to scaffold, particularly a kind of large span assembly type builder's jack support system.
Background technology
Scaffold is absolutely necessary in building operations, along with building is more and more higher, the use of builder's jack is also more and more wider, but existing builder's jack all is vertical rod basically to be directly arranged on the shaped steel of encorbelmenting or on the gusseted, whenever stride vertical rod and all need shaped steel of encorbelmenting or gusseted, steel using amount is very big, and wastes time and energy when installing.
Encorbelmenting, anchored end need stretch into certain-length in the floor behind the shaped steel; run into positions such as staircase and often do not have the enough length of going deep into; more seriously; the situation that shaped steel can't be arranged often appears in the rotation angle position at building; even string out, the anchored end that also can occur several shaped steel usually concentrates on the rough sledding such as middle part of a floor.
