Description
Technical field
The invention belongs to building machinery technical field, particularly relate to the internal-climbing tower crane supporting of a kind of band shearing frame
Structure.
Background technology
Plug-in or inner climbing type two ways is generally used to be supported on and build for high-rise and high-rise building derrick crane
Build on thing, and raise along with the rising of building, plug-in or in climb be to determine according to the needs of architecture construction.
The internal-climbing tower crane supporting construction of presently used band shearing frame substantially has two kinds of versions.One is
The supporting construction being made up of parts such as two girders that climb, bearing, supporting legs, girder two ends and wall connecting.Inner climbing type tower crane is pacified
It is contained in elevator hoistways, due to installation constitution requirement, it is necessary on elevator shear wall, bury built-in fitting, four of two girders
Bearing is bolted with the built-in fitting bearing buried in advance, this in climb supporting construction fairly simple.But owing to tower crane is propped up
Seating is in girder upper surface, and tower crane is delivered to the horizontal force of girder and produces moment of torsion on girder, and is delivered on the bearing at two ends,
It is unfavorable for girder and the stress of two end bearings.Also have installs horizontal brace rod between two girders additional, but due to master
The torsion of beam does not has inhibitory action, can not improve the stress of girder, owing to there being tower crane support frame on girder bearing,
So the stress that level connection joint pole pair improves beam body does not has practical significance.
Climb supporting construction in another kind in the first, climb on the basis of structure the horizontal hound of side installation at girder,
Generally three horizontal hounds, the other end of bar is connected with body of wall, four ends of two girders respectively with left and right two face wall
Body be connected, connect by tower crane support frame between two girders, this in climb structure by horizontal hound by tower crane generation
Horizontal force be directly delivered on body of wall, it is possible to improve girder beam body and the stress of girder two ends body of wall.But need to increase
Support level hound with wall connecting at built-in fitting, installation process is the most more complicated, and add tower crane supporting become
This.
Climbing tower crane supporting construction of the present invention, including the shearing frame between two girders, two girders,
Bearing and connector, described shearing frame is two, be arranged in parallel between two girders, symmetrical along two girder normal direction centrages, often
Individual girder two ends are separately installed with the connector being connected with wall body built-in fitting.Inside climb supporting construction girder by the horizontal masterpiece of tower crane
Used time will produce moment of torsion, and torsional deflection occurs, and shearing frame oblique fulcrum bar has the effect keeping shearing frame shape invariance, with shearing
After frame connects, the two respective torsional deflections of girder suffer restraints, thus respective for girder torque axis changes to hanging down on beam end support
Straight load, improves the stress of girder, the stress of end of main beam junction, also improves support girder body of wall simultaneously
Stress, and this supporting construction installation process is simple, easily operates, it is possible to reduce support cost.
Summary of the invention
For the technical problem of above-mentioned existence, the present invention provides the internal-climbing tower crane supporting of a kind of band shearing frame to tie
Structure, it can effectively improve support girder and end of main beam and support the stress of body of wall, and structure fabrication is easy, installs letter
Single, working performance can be improved, reduce overall support cost.
It is an object of the invention to be achieved through the following technical solutions:
A kind of internal-climbing tower crane supporting construction of band shearing frame, including the shearing frame between two girders, two girders,
Bearing and connector, described shearing frame is two, be arranged in parallel between two girders, symmetrical along two girder centrages, corresponding
Seat is put, and is provided with supports the bearing of tower crane installing the girder upper surface at shearing frame, each girder two ends be separately installed with
The connector that wall body built-in fitting connects.
Further, described shearing frame is the triangular structure being made up of horizontal strut, vertical pole and inclined support bar,
At triangle point, it may be assumed that inclined support bar two ends and horizontal strut one end are all with pin shaft hole.
Further, described shearing frame is to constitute by being provided with inclined support bar in rectangular frame, its corner with girder ear
The pin shaft hole that plate connects.
Further, described inclined support bar is a diagonal of rectangular frame, and rectangular frame is configured to triangle knot
Structure.
Further, the rectangular frame of described shearing frame is welded by two horizontal struts, two vertical poles and inclined support bar
Connecing composition, horizontal strut one end has pin shaft hole, the other end to be welded on inclined support bar, and vertical pole two ends are respectively welded at level
On pole and inclined support bar, all there is pin shaft hole at inclined support bar two ends, by the pin shaft hole on horizontal strut and inclined support bar respectively
It is connected with the otic placode on the girder of both sides.
Further, under described shearing frame, horizontal strut is connected end and is provided with keeper with girder, and girder is connected
Otic placode be provided with location-plate, during installation, keeper is placed on location-plate, it is ensured that shearing rack-mounted enter after on each connecting hole and girder
The connecting hole of otic placode is the most identical, makes shearing frame easily install.
Further, described keeper is square tube, pipe or round steel.
Further, described pin shaft hole both sides are respectively provided with the first reinforcing plate, the second reinforcing plate is strengthened.
The invention have the benefit that
1. the present invention uses two shearing shelf structures, is respectively symmetrically and is connected with girder, and tower crane is acted on by horizontal force, inside climbs
To produce moment of torsion when supporting construction girder is by tower crane horizontal force action, and torsional deflection occurs, shearing frame oblique fulcrum bar has guarantor
Holding the effect of shearing frame shape invariance, after being connected with shearing frame, the two respective torsional deflections of girder suffer restraints, thus by girder
Respective torque axis changes to the vertical load on beam end support, improves the stress of girder, being subject to of end of main beam junction
Power state, also improves the stress of support girder body of wall simultaneously.
There is pin shaft hole at shearing shelf structure corner the most of the present invention, connected with being connected otic placode on girder by bearing pin, convenient peace
Assembly and disassembly work；The oblique fulcrum bar of shearing frame is a diagonal of rectangle frame, and rectangular configuration is configured to triangular structure, protects
The stability of card structure.
