Description

A compensating beam for aerial work

Technical Field

The utility model relates to a compensating beam, especially a compensating beam for eminence operation.

Background

With the continuous development of construction technology, the grid structure is rapidly developed and widely applied in nearly thirty or four years due to the characteristics of large rigidity, good integrity, good earthquake resistance, light dead weight, steel saving, good adaptability and the like. The traditional net rack mounting methods at present comprise common construction methods such as a high-altitude assembling method, a lifting method, an integral hoisting method and a jacking method. The high-altitude assembly method needs to consume a large amount of frame materials to set up an operation platform, and has higher material lease and labor cost. Although the integral hoisting in-place method has the characteristics of simple and convenient construction, short construction period, easy guarantee of engineering quality and the like, the overhead cost of a crane is too high, the crane walking road needs to be treated, the construction cost is very high, the key is limited by the site, and the construction requirement is difficult to meet; although hydraulic pressure whole lifting is not restricted by the place, but has higher requirement as the reliable hoisting fulcrum to original structure, and the structural steel column can not satisfy the bearing capacity requirement. The jacking method integrates the advantages, the net rack is assembled on the ground, safety and time saving are realized, the assembling quality is convenient to guarantee, and the installation of the jacking frame body is not limited by the field and the surrounding environment, so that the jacking method is generally applied to the construction of the net rack structure with balanced weight.

However, the roof of a certain project is a combined type eccentric overweight slope angle steel structure, the main structure is a diagonal quadrangular pyramid net rack, if the roof is jacked by adopting the traditional method, only the lower chord ball of the net rack can be jacked, and because the diagonal quadrangular pyramid net rack and the lower chord rod piece are arranged right below the upper chord ball of the net rack, the jacking of the jacking frame is blocked, and jacking cannot be realized. And the lower chord ball of the supporting net rack inevitably improves the ground assembling height of the steel structure, increases the work load at high places and increases the installation difficulty of the jacking frame. Therefore, how to realize the supporting of the string ball on the net rack becomes a problem which needs to be solved urgently in the industry.

Disclosure of Invention

The utility model provides a solve the technical problem who exists among the known art and provide a compensating beam for the aerial work, this compensating beam can realize the upper portion back timber of steel construction.

The utility model discloses a solve the technical scheme that technical problem that exists among the well-known technique took and be: the utility model provides a compensating beam roof beam for eminence operation, includes four cantilever beams that are "ten" font level and arrange be equipped with the supporting part above the cantilever beam's the cantilever end, four the intersection top rigid coupling of cantilever beam has draws the gusset plate to one side the rigid coupling has the support pole setting on drawing the gusset plate to one side support pole setting and four respectively be equipped with a diagonal draw pole between the cantilever beam.

The cantilever beam is formed by welding H-shaped steel.

The two sides of the upper wing plate at the cantilever end of the cantilever beam are respectively welded with a widened bottom lining plate, the two sides of the web plate at the cantilever end of the cantilever beam are respectively provided with a reinforcing rib plate, the top edge of each reinforcing rib plate is connected with the corresponding widened bottom lining plate and the corresponding upper wing plate, and the bottom edge of each reinforcing rib plate is connected with the corresponding lower wing plate.

The utility model has the advantages and positive effects that: the compensating beam can stretch into the inside of the operation object, and then avoids stopping of the lower structure, realizes upper supporting or lower supporting, and when the compensating beam is used for the upper supporting of the large structure, the ground assembling height of the large structure can be greatly reduced, and high-altitude operation is avoided. The large-scale structure is assembled on the ground, so that the quality of welding seams is convenient to ensure, quality inspection such as welding seam detection, component installation position check and the like is convenient to ensure, the installation quality of the large-scale structure is convenient to ensure, vertical transportation and hoisting operation can be reduced, and potential safety hazards of high-altitude operation are avoided; the large-scale structure is assembled on the ground, so that the jacking frame is convenient to install, the construction efficiency is high, and the construction quality is easy to guarantee. Meanwhile, the balance beam enables the supporting point of the jacking frame to be changed from one to four, jacking counter force is dispersed to a certain degree, and supporting stress is enabled to be more stable. Adopt the diagonal draw bar to drawknot the cantilever beam in supporting the pole setting, can greatly strengthen the bending resistance of cantilever beam. The utility model discloses not only can be used for the jacking of large-scale structure, can also be used for the jacking of shell component and pipe class component or promote or hoist and mount etc. need buckle the shell component this moment and put on the compensating beam, erect the pipe class component on the compensating beam. No matter adopt the utility model discloses jacking large-scale structure, jacking, promotion or hoist and mount shell component or pipe class component can all guarantee operation object stable in structure, and indeformable keeps the structure form and position tolerance of operation object in the within range that allows.
