Description
Technical field
The present invention relates to Steel Structure Installation field, specifically a kind of large girder is vertical to spell anti-dumping coating method.
Background technique
In recent years, with the development of national economy and construction industry, height is larger, the biggish real abdomen large girder of span is in industry
Build in (especially power plant, steel mill, boiler factory etc.) and civil buildings (large span spatial structure) using more and more, large girder
Segmental machining is generally carried out by factory, then is installed to the mode that construction site carries out integral assembling lifting, large girder is segmented
Stood during spelling at the construction field (site), due to highly higher, there is a very big risk of toppling, especially at the construction field (site) working space by
When limit, it is likely that can have more large girders close to the case where vertical spelling, this just more exacerbates the analysis continuously toppled, mesh
The preceding measure generally taken mainly is welded fashioned iron between large girder and is reinforced, and the deficiency of this reinforcing mode is can be to finished product
Steel member forms local failure, influences component presentation quality even safe mass, while the structural stability after its fixation
It is insufficient.
Summary of the invention
It is an object of the invention to overcome drawbacks described above, providing one kind can also protect while not having an impact to steel member
Hold the stable anti-dumping coating method of ruggedized construction.
In order to achieve the above object, the present invention is implemented as follows:
A kind of vertical spelling anti-dumping coating method of large girder, including
Step 1 prepares bracket: the bracket includes linking beam, fastener, turnbuckle, flexible support and bolt；
Step 2 completes linking beam in factory process according to the vertical flange dimensions for spelling large girder in scene, and linking beam uses H profile steel, work
Word steel and fastener, turnbuckle and plain bolt purchase finished parts, and flexible support is completed by live reinforcement fabrication；
Step 3 chooses the vertical end two for spelling large girder, intermediate two positions as installation flexible support, installs flexible branch
Support is tensioned turnbuckle；
Step 4, the linking beam and flexible support for installing the large girder of end two, make two large girders in end formed one it is stable
Structural system；
Step 5, with the vertical increase for spelling large girder quantity, linking beam and local flexible support are successively installed, make it is entire side by side
More large girders are always a stable structural system；
Step 6, when hanging large girder, remove linking beam and flexible support one by one, thus before hanging last two large girders,
Entire large girder system is always stable structural system.
The kind large girder is vertical to spell anti-dumping coating method, and the specific structure of bracket is: two linking beams are arranged in parallel and lead to
It crosses fastener and the upper lower flange of large girder is connect with two linking beams and passes through live reinforcing bar and two linking beams are intersected
It tenses.
Bracket in this anti-dumping coating method is the standard component in factory process, be may be reused, and waste of material is avoided；Together
When, large girder is connected by this method, and overturn-preventing effect is good, can be formed always in vertical spell of large girder with during hanging one by one
Stable structural system；Further, the bracket in this anti-dumping coating method, it is adaptable, can according to vertical spelling large girder height,
Quantity is adjusted；To not will cause damage to steel member；And remove, install it is also all very convenient quick.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of bracket in this method.
Fig. 2 is the structural schematic diagram after formation system in this method.
Specific embodiment
The present invention is further illustrated below by way of specific embodiment.
As shown in Figure 1 and Figure 2, the vertical spelling anti-dumping coating method of a kind of large girder, including
Step 1 prepares bracket: the bracket includes linking beam 1, fastener 2, turnbuckle, flexible support 3 and bolt；
Step 2 completes linking beam 1 in factory process according to the vertical flange dimensions for spelling large girder 4 in scene, and linking beam 1 uses H-type
Steel, I-steel and fastener, turnbuckle and plain bolt purchase finished parts, and flexible support 3 is completed by live reinforcement fabrication；
Step 3 chooses the vertical end two for spelling large girder 4, intermediate two positions as installation flexible support 3, and installation is flexible
Support 3 is tensioned turnbuckle；
Step 4, the linking beam 1 and flexible support 3 for installing two large girders 4 in end make the large girder 4 of end two form one surely
Fixed structural system；
Step 5, with the vertical increase for spelling large girder quantity, linking beam and local flexible support are successively installed, make it is entire side by side
More large girders are always a stable structural system；
Step 6, when hanging large girder, remove linking beam and flexible support one by one, thus before hanging last two large girders,
Entire large girder system is always stable structural system.
The kind large girder is vertical to spell anti-dumping coating method, and the specific structure of bracket is: two linking beams are arranged in parallel and lead to
It crosses fastener and the upper lower flange of large girder is connect with two linking beams and passes through live reinforcing bar and two linking beams are intersected
It tenses.
Bracket in this anti-dumping coating method is the standard component in factory process, be may be reused, and waste of material is avoided；Together
When, large girder is connected by this method, and overturn-preventing effect is good, can be formed always in vertical spell of large girder with during hanging one by one
Stable structural system；Further, the bracket in this anti-dumping coating method, it is adaptable, can according to vertical spelling large girder height,
Quantity is adjusted；To not will cause damage to steel member；And remove, install it is also all very convenient quick.
