Abstract
This method discloses a kind of for running the construction method that light rail station special-shaped steel structure traction sliding is installed on line, this method relies on special-shaped steel structure installing engineering, it is big according to long-span special Steel Structure Installation engineering difficulty of construction, duration is nervous, construction site is narrow and small, it is impossible to the new method for carrying out the requirement of lifting in situ and designing.Sliding construction is drawn for steel construction, innovation is in steel structural upright column side increase bracket structure, it is used as the support power transmission point and stopping means of integral slipping, by analyzing under each working condition, structural internal force, deformation distribution, the control of steel construction posture analysis and resistance to overturning can adjust Structure Attitude in time, it can play a part of spacing preventing steel construction overall offset again, it is ensured that traction security.
Description
Technical field
It is used to run the construction method that light rail station special-shaped steel structure traction sliding is installed on line, category the present invention relates to a kind of
In light rail station technical field of construction.
Background technology
Jing-Bin light rail Zhang Guizhuan stations engineering is Tianjin City to Binhai New District rail rapid transit first stage of the project Zhang Guizhuan stations
Project to be continued, the engineering mainly builds reserved station in the case where ensuring that Zhang Guizhuan stations are normally run.Wherein station across
Spend for 17.20 meters, post is away from for 9.6 meters, and 12.8 meters, and overall structure is " bridge of standing unification " frame structure, it is necessary to normal in light rail
It is pin-ended arch-shaped steel frame that load-carrying members are installed under running situation.No. 9 line Zhang Guizhuan stations project to be continued large spans of Jing-Bin light rail
Different formed steel construction installation mainly faces construction safety risk greatly, and the duration is nervous, and surrounding environment is complicated, it is impossible to carry out steel construction
The problems such as original position lifting.
The content of the invention
The present invention is to solve the technical problem that train in light rail enlarging is normally run, and the one kind provided is used to run line
The construction method that upper light rail station special-shaped steel structure is installed.
It is a kind of to be used to run the construction method that light rail station special-shaped steel structure traction sliding is installed on line, by steel column
Upper setting bracket, in the long 16#a channel-section steels of bracket lower weld 200mm as sliding block, patch weldering stainless steel plate, passes through inside channel-section steel
Bracket, channel-section steel realize sliding of the steelframe on slideway.Slideway is located on beams of concrete center line, and 24#b works are set up in slipway beam bottom
Word steel makes track be higher than beams of concrete 20cm as support.304 stainless steel plates are completely spread on slipway beam and weld jail with slipway beam
Gu.Silicone grease lubricant is smeared when using on stainless steel.
By increasing bracket device on steel column, steel construction need not remove cunning immediately after jack jacking is fixedly mounted
Duct device, constructs in steel construction all sliding installation process, is installed on girder steel bracket and FY15-7 folders are installed in anchor slot, groove
Piece anchor tool system fixes steel strand wires, the effect of anchor existing anchorage steel strand wires, while also there is adjustment steel strand wires position.
Pass through fixed steel strand wires, it is ensured that azimuth deviation does not occur for pulling force when steel construction is drawn, effectively prevent that clamp rail phenomenon occurs during sliding.
The duration is saved compared to conventional construction method；Meanwhile, jack jacking position be bracket, the change of stress point and by
The increase of power area, substantially increases stability during steelframe jack-up, construction safety has been effectively ensured；Compared to steel column, bracket
Lifting surface area is larger, and steel column is more prone to ensure installation accuracy and speed when being fixedly mounted.
Brief description of the drawings
Fig. 1 is main span steel roof truss upright column bracket and slide block structure figure.
Fig. 2 is main span steel roof truss upright column bracket and slide block structure A-A schematic diagrames.
Embodiment
The 1st, bracket and sliding block are set on the inside of girder steel
Creative is respectively provided with bracket on the inside of every root posts of Pin 2, in the long 16#a channel-section steels conducts of bracket lower weld 200mm
Sliding block, the patch weldering stainless steel plate inside channel-section steel.Meanwhile, installation of slide track is on the inside of the steel column of both sides.Slideway is located at beams of concrete center
On line, 24#b I-steel is set up as support in slipway beam bottom, track is higher than beams of concrete 20cm.Completely spread on slipway beam
304 stainless steel plates and slipway beam firm welding.Silicone grease lubricant is smeared when using on stainless steel.Main span steel roof truss upright column bracket
And slide block structure figure is shown in Fig. 1-Fig. 2.
As shown in figure 1, setting bracket device on the inside of steel column, slid by the use of bracket device as steel construction integrally dragging
Power transmission point, control steel construction horizontal sliding displacement.
2nd, girder steel assembly and pushing tow
Steel structure assembling place is assembled into Pin, and installation bracket and sliding block on steel column to steel column girder steel at the construction field (site).
Installed on girder steel bracket and FY15-7 intermediate plates anchor tool system fixation steel strand wires are installed in anchor slot, groove.Led using 3 steel strand wires
Draw pushing tow operation., will be per Pin steel constructions for connecting bracket and steel strand wires by installing anchor slab, anchor slot and steel construction slideway
Connect as one, wherein anchor existing anchorage steel strand wires are acted on, while also there is adjustment steel strand wires position.
