Description
Technical field
The utility model relates to a kind of construction work device, specifically be a kind of big cantilever frame encorbelment the end and temporary support columns between linkage.
Background technology
The canopy formula building that the grandstand of large public building is much more general to adopt the big cantilever frame by steel work or reinforced concrete structure to cooperate purlin and roof panel to constitute.Such construction techniques is as follows:
Carry out the construction of single truss structure earlier: the big cantilever frame that prefabrication is good is installed at the scene, and with the bottom and the basic fixed of the big cantilever frame of single Pin, and the middle-end of big cantilever frame is fixed on the frame column.For the stability that guarantees the follow-up construction of truss, prevent single truss structure distortion, also the end of encorbelmenting of big cantilever frame need be supported on the temporary support columns of temporarily constructing.At this moment, single truss structure installation is finished.
Repeat above-mentioned steps again, finish until whole truss installations.
Then, purlin, roof panel are installed on the good big cantilever frame of many Pin of construction, roofing supports and other auxiliary roof structures such as (insulation, waterproofing materialss), the monolithic roof structure.
At last, dismantle the temporary support columns of the big cantilever frame of every Pin.
Direct pressure-bearing contacts between encorbelment end and the temporary support columns (top) of the big cantilever frame of prior art.
There is following defective in the end of encorbelmenting of the big cantilever frame of prior art with syndeton between the temporary support columns: because direct pressure-bearing contacts between encorbelment end and the temporary support columns (top) of big cantilever frame, so when whole roof structures construction finishing needs are dismantled temporary support columns, because the load of roof structure is big, scale error when the normal deformation of big cantilever frame and canopy formula are built each member installation, make encorbelmenting of big cantilever frame produce bigger pressure between end and the temporary support columns, cause the dismounting work of temporary support columns to become very difficult, in addition accidents caused easily.
The utility model content
The technical problems to be solved in the utility model is, a kind of easy separation is provided, makes the linkage between end and the temporary support columns of encorbelmenting of the simple and safe big cantilever frame of temporary support columns dismounting.
Technical solution of the present utility model is, a kind of linkage between end and the temporary support columns of encorbelmenting of the big cantilever frame with following structure is provided, encorbelmenting of described big cantilever frame is provided with unloader box between end and the temporary support columns, described unloader box comprises the steel casing that is fixed on the temporary support columns top, the base plate center fixation of described steel casing has hydraulic jack, the top board center of described steel casing is provided with the circular hole that feed flow presses jack to pass, two groups of wedge shape billets are installed on the top board of described circular hole both sides, every group of wedge shape billet comprises at least four superimposed wedge shape billets, one end face of the top of described every group of wedge shape billet is against the bottom surface of the end of encorbelmenting of big cantilever frame, and the absolute altitude of one end face of the top of described every group of wedge shape billet equals the design elevation of bottom surface of the end of encorbelmenting of big cantilever frame.
After adopting above structure, the big cantilever frame of the utility model encorbelment the end and temporary support columns between linkage compared with prior art, have the following advantages:
Because indirect pressure-bearing contacts between encorbelment end and the temporary support columns (top) of big cantilever frame, be that encorbelmenting of big cantilever frame held two end face of the top that is pressed on two groups of wedge shape billets, so when whole roof structures construction finishing needs are dismantled temporary support columns, though have bigger pressure between the two wedge shape billets of the encorbelment end and the top of big cantilever frame, but the constructor can start hydraulic jack, and begin when encorbelmenting end in contact when the piston of hydraulic jack, just can produce and make the active force of end of encorbelmenting to top offset, continue jigger lifting piston, the slit that both are disengaged appears between end and the wedge shape billet until encorbelmenting, hydraulic jack is kept stable state, extract whole wedge shape billets out, at last hydraulic jack is slowly fallen after rise, the encorbelment bottom of end also is moved to design elevation thereupon, and just making encorbelments holds and unloader box disengages fully.Like this, the unloading process of temporary support columns becomes simply, has also avoided occurring security incident.
As improvement, the base plate center fixation of described steel casing has hydraulic jack to be meant, the base plate of described steel casing is provided with two mounting holes that are symmetrically distributed along diagonal, described hydraulic jack is by on the base plate that is bolted to the steel casing that passes mounting hole, like this, just can be as required in the fixing hydraulic jack of different size of steel box bottom.
As improving again, two groups of wedge shape billets are installed on the top board of described circular hole both sides to be meant, the circular hole both sides are fixed with the cylinder spacer pin of two epireliefs on the top board of described steel casing, the bottom surface of minimum wedge shape billet is provided with the blind hole that cooperates with the cylinder spacer pin in every group of wedge shape billet, this piece wedge shape billet by cylinder spacer pin and steel casing level to spacing, like this, make that fixing of wedge shape billet and steel casing is more firm.
