Description
Technical field
The present invention relates to be used in the steel truss girder erection construction equipment and the method for turning of large steel girder member bar turning.
Background technology
Steel truss girder is that the rod member spelling by one group of group forms, each rod member of steel truss girder after steel truss girder professional production producer completes, through the water route or the land route be transported to bridge site, piece together lifting, depositing and piecing together in advance then in advance in the building site.
Steel truss girder needs rod member is pieced together in advance before installation, and its purpose is exactly to reduce the number of times of the lifting when setting a roof beam in place and the workload of work high above the ground assembly unit, accelerating construction progress.The pre-method of piecing together of steel girder member bar is exactly before steel truss girder sets up, the part rod member that is associated in advance on ground (pre-piece together) with dashing the nail location and the bolted on connection of working is in the same place.
Because of the certain directionality of setting up of upper and lower chord member, again because of the condition restriction of water route or land route transportation, the direction of the rod member of coming over is not necessarily with to set up direction consistent, so we must be provided with a supporting equipment for supporting patient with burn in the pre-field of piecing together according to the needs that set up, with this reliability and safety of satisfying the construction needs and guaranteeing steel girder member bar turning.
Along with construction requirements is also more and more higher, the scale of construction of single steel girder member bar is also more done bigger, and because of the employing of new technologies such as orthotropic plate makes that attached a lot of other primary structural components are (thiner on the single rod member, fragile), in order to adapt to this variation, in steel girder member bar assembly process in advance, adopt special equipment for supporting patient with burn to stand up, avoid unnecessary deformation and damage in the process of standing up with regard to requiring.
Now standing up of steel girder member bar generally is on the ground or directly utilizes lifting appliance to stand up in the sand pit, because of the rod member scale of construction big, it is very dangerous standing up operation as direct employing loop wheel machine, moreover the rod member accessory structure is many, is easy to also cause that the plastic strain of rod member and application pull-up fall.Carry out the research of steel truss girder equipment for supporting patient with burn, be intended to satisfy the construction needs, the better protection steel girder member bar, thus satisfy the quality requirement that steel truss girder sets up.
Summary of the invention
The objective of the invention is at above-mentioned present situation, aim to provide a kind of safe and reliable large steel girder member bar turning device and member bar turning method.
The implementation of purpose of the present invention is, large steel girder member bar turning device, single steel leg 3 is installed on the end concrete pedestal 1, on single steel leg 3 the end rotary buckle 5 that can connect steel girder member bar 7 is installed, on the middle part concrete pedestal 2 two steel legs 4 that can connect steel girder member bar 7 are installed, the upset wheel disc 6 that can connect steel girder member bar 7 is blocked on two steel legs 4 tops, and upset wheel disc 6 bottoms are by locking device 8 lockings.
The large steel girder member bar turning device member bar turning method, switching process is as follows:
1) earlier end rotary buckle 5 and steel girder member bar 7 ends are connected;
2) wherein half of wheel disc 6 of will overturning is installed on the steel leg on concrete pedestal 2 tops, middle part, by the locking device 8 wheel disc fixation of will overturning, installs the pad thing then;
3) utilize lifting appliance that steel girder member bar 7 to be flipped is in place, half upset wheel disc 6 in addition is installed, the good pad thing 11 of pad is bolted on;
4) wire rope and hoist engine are installed;
5) device 8 that unlocks utilizes hoist engine to make steel girder member bar 7 overturn together in company with upset wheel discs 8 and end rotary buckle 5 and puts in place;
6) untie upset wheel disc connecting bolt, the steel girder member bar upset is finished.
Adopt this equipment for supporting patient with burn, steel girder member bar 7 one ends are positioned on the end rotary buckle 5, and the centre is installed on two steel legs 4.
This equipment for supporting patient with burn can better protect the girder steel rod member, can fully guarantee reliability and safety in the girder steel member bar turning process, thus the good girder steel rod member of better protection, and can improve the upset work efficiency; Steel girder member bar is indeformable in the process of standing up, do not damage.This equipment for supporting patient with burn is simple in structure, is fit to the field machining manufacturing, overturn reliable and secure, efficient is high, turning operation is simple, make things convenient for.

The specific embodiment
With reference to Fig. 1,2,3, single steel leg 3 is installed on the end concrete pedestal 1 of this equipment for supporting patient with burn, on single steel leg 3 the end rotary buckle 5 that can connect steel girder member bar 7 is installed, on the middle part concrete pedestal 2 two steel legs 4 that can connect steel girder member bar 7 are installed, the upset wheel disc 6 that can connect steel girder member bar 7 is blocked on two steel legs 4 tops, and upset wheel disc 6 bottoms are by locking device 8 lockings.
Large steel girder member bar upset, by two independently pedestal finish, its pedestal is that concrete is built and formed.One of them is provided in a side of the end concrete pedestal 1 of Rod end, and another is located at the middle part concrete pedestal 2 at rod member middle part, thereby can adapt to the rod member of different length.Determine two pedestals height separately according to the height of all rod members, determine distance between the pedestal according to the length of all rod members, the external force of being born by pedestal is determined planar dimension separately then.
The large steel girder member bar end is connected with end rotary buckle 5, is bearing on the single steel leg 3 on the end pedestal top; The girder steel middle part is connected with upset wheel disc 6, between copy with wooden unit and rubber pad thing 11 real fixing, thereby the rod member that adapts to different cross section is on the two steel legs 4 in the middle part of the upset wheel disc is bearing on the pedestal top, fixing by locking device 8 between upset wheel disc and the middle part concrete pedestal 2.Determine the size of end rotary buckle and upset wheel disc according to the cross section of rod member, and determine the size of steel leg according to stressing conditions;
With wire rope around the upset wheel disc on, be divided into initiatively haulage cable 9 and brake wire 10, utilize 2 hoist engines to control its upset then, a hoist engine initiatively draws the girder steel upset, and another hoist engine loosens wire rope and controls its velocity of rotation or braking.
Switching process of the present invention is as follows:
1) earlier end rotary buckle 5 and steel girder member bar 7 ends are connected;
