Abstract
The utility model relates to steel structure construction, in particular to a steel structure jacking anti-skidding device. The steel structure jacking anti-skidding device comprises an annular part and a rectangular part, wherein one surface of the annular part and one surface of the rectangular part are concave surfaces, the other surface of the annular part and the other surface of the rectangular part are straight surfaces, and the annular part and the rectangular part are welded together through the straight surfaces. The anti-skidding device further comprises a rectangular gasket group and a round gasket group, wherein the rectangular gasket group is matched with the rectangular part in shape, and the round gasket group is matched with the rectangular part in shape. The steel structure jacking anti-skidding device increases contact areas, increases stressed areas, enables completes to be stressed reasonably, increases jacking stability, and is safe to construct.
Description
Technical field
The utility model relates to Construction of Steel Structure, relates in particular to a kind of steel work lift-up device.
Background technology
Along with the more and more application in industrial, civilian, public building of this form of structure of steel work, so that the method for Steel Structure Installation is also more and more.For complicated, the highly higher Construction of Steel Structure of profile, tend to adopt the mounting method of hydraulic jack integral jacking steel work, and generally all be the place, stressed member bottom flange that directly withstands on steel structure member with jack when jacking.Because the bearing top surface area of jack is less, the contact surface of itself and structure is also less, thus when operation so that the structural member local pressure is excessive, Load concentration, make easily the deformation of member excessive and damage, and in operation process, also can have the hidden danger of member and jack slippage.
Summary of the invention
The utility model is intended to address the aforementioned drawbacks, and a kind of steel work jacking shoe is provided.The utility model increases contact surface, increases lifting surface area; Make member stress more reasonable; And this device has the jacking of increasing stability simultaneously, makes construction safer.
For addressing the above problem, the utility model is to realize like this, a kind of steel work jacking shoe, it comprises an annular element and a rectangular-shaped piece, the one side of described annular element and rectangular-shaped piece is concave surface, another side is flat face, and both weld together with its flat face separately, and described shoe also comprises respectively rectangular washer group and the circular gasket group that is complementary with annular element and rectangular-shaped piece shape.
Described a kind of steel work jacking shoe, the concave surface of described annular element is the circular depressed that diameter dwindles step by step, and described circular gasket is the boss of scalariform of organizing a performance.
Described a kind of steel work jacking shoe, the concave surface of described rectangular-shaped piece is the step of both ends high, middle low, and described rectangular washer has the low step in middle high two ends.
The utility model is located at jack and needs and mainly is comprised of annular element and rectangular-shaped piece two parts between the member of jacking, and the difform pad of the many groups of attached outfit.The utility model can increase contact surface, increases lifting surface area.Make member stress more reasonable; And this device has the jacking of increasing stability simultaneously, makes construction safer.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is the utility model schematic diagram;
Fig. 2 is use state diagram of the present utility model.
The specific embodiment
See also Fig. 1, for addressing the above problem, a kind of steel work jacking of the utility model shoe, it comprises an annular element 2 and a rectangular-shaped piece 1, the one side of described annular element 2 and rectangular-shaped piece 1 is concave surface, another sheet flat face, both weld together with its flat face separately, and described shoe also comprises respectively rectangular washer group and the circular gasket group that is complementary with annular element and rectangular-shaped piece shape.
As examples of implementation of the present utility model, the concave surface of described annular element is the circular depressed that diameter dwindles step by step, and described circular gasket is the boss of scalariform of organizing a performance; The concave surface of described rectangular-shaped piece is the step of both ends high, middle low, and described rectangular washer has the low step in middle high two ends.
Claims (3)
1. steel work jacking shoe, it is characterized in that, it comprises an annular element and a rectangular-shaped piece, the one side of described annular element and rectangular-shaped piece is concave surface, another side is flat face, both weld together with its flat face separately, and described shoe also comprises respectively rectangular washer group and the circular gasket group that is complementary with annular element and rectangular-shaped piece shape.
2. a kind of steel work jacking shoe according to claim 1 is characterized in that the concave surface of described annular element is the circular depressed that diameter dwindles step by step, and described circular gasket is the boss of scalariform of organizing a performance.
