Description
Technical Field
The utility model belongs to the technical field of steel construction engineering construction, concretely relates to be used for large-span conversion steel truss strutting arrangement.
Background
The modern building has unique design and complex structure, and the conversion steel truss is suitable for building multi-story high-rise large-span structures due to the characteristics of light weight, high strength, simple and convenient construction, good ductility and seismic performance and the like. And the conversion steel truss inevitably generates downward deflection deformation under the action of large upper load, thereby leading to front and rear construction interface cracks. By preloading and arch eliminating the reasonably arched steel truss, cracks can be avoided from being generated on the weak plane of the boundary. The traditional preloading method is mostly a heavy loading mode such as sand bags, concrete blocks and the like at present, and the mode needs a large amount of substances, has complex procedures and is difficult to operate safely.

In order to solve the problem, the utility model discloses a be used for large-span conversion steel truss strutting arrangement, design benefit, easy operation, the safety and stability has guaranteed that the state after the final completion of conversion steel truss construction keeps unanimous with the design status, and has solved the adverse effect such as the interface crack that arouses because of warping around the construction.
In order to achieve the above purpose, the technical scheme of the utility model is as follows:
the utility model provides a be used for large-span conversion steel truss strutting arrangement, is including conversion steel truss, support bed-jig, sleeve pipe, punching jack, hydraulic power unit, stroke sensor, the sleeve pipe sets up in the bottom surface, support the bed-jig bottom and insert in the sleeve pipe to bury the piece with the column base on the bottom surface and reserve the clearance, the setting of conversion steel truss is in supporting the bed-jig top, it is equipped with the steel corbel to support the bed-jig below, and the sleeve pipe outside is equipped with the steel buttress, punching jack sets up between steel corbel and steel buttress, and punching jack passes through hydraulic pressure oil pipe and is connected with hydraulic power unit, and punching jack sets up stroke sensor.
As an improvement of the utility model, the supporting jig frame is a steel pipe supporting jig frame.
As an improvement of the utility model, the inner diameter of the sleeve is 2-5mm larger than the outer diameter of the supporting jig frame.
As an improvement of the present invention, the number of the center-penetrating jacks is two or four.
As an improvement of the utility model, the gap is 5-20 cm.
The utility model has the advantages that:
the support device for the large-span conversion steel truss has the advantages of simple structure, convenient use, strong practicability, low investment cost, safety and reliability; and adverse effects such as interface cracks caused by deformation in the construction process are effectively solved.
