Base is as the counterforce device of snubber 113, and when movable roof 2 is during in complete opening, the payload values calculating is to its intensity and deformation checking computations.
The method that the each parts of the utility model folding house roof rail system are installed is specially:
Thinking is installed: fixing roof system 1 carries out rail beam rest 5 when installation and installs, rail beam rest 5 carries out the installation of Accessory Members between rail beam 41 and rail beam 41 after installing and checking, on rail beam 41, lay again track 61, finally install car stop 10 and lower car bumper 11.
The installation of rail beam rest 5.Rail beam rest 5 is completed by factory process, and point upper and lower two parts mail to scene, and top comprises top bracket 59 and two semicircle ring flat-plates 54, and bottom is the circular ring flat-plates 54 of two halves.When fixing roof truss is installed, utilize total powerstation accurately to locate, rail beam rest 5 is temporarily fixed in truss web 12, after calibration, circular two halves ring flat-plate 54 is stitched together, enclose along pipe boxing one simultaneously.
The installation of rail beam 41.On rail beam 41, directly lay track 61, track 61 soffits and rail beam 41 upper surfaces fit together, and must not have space, and because the installation accuracy of track 61 is had relatively high expectations, the therefore making to rail beam 41, installation accuracy require also comparatively harsh.Consider after fixing roof system bracing frame is removed and can produce a certain amount of downwarp, therefore rail beam need be installed after fixing roof system bracing frame is removed; Rail beam 41 by total is carried out to emulation simulation during construction analysis, obtains the downwarp value of each point before modeling; In the time that rail beam 41 carries out modeling in-depth, rail beam 41 downwarp factors are taken into account, guarantee as much as possible member precision, reduce alignment error.Rail beam 41 is made the complete scene that sends to according to member detail drawing in factory process, according to on-the-spot actual, choosing rational loop wheel machine lifts, after check location, link together by bolt 7 and rail beam rest 5, rail beam rest 5 top board upper bolt holes are slotted hole, facilitate installation, the calibration of rail beam 41.
The installation of track 61.Track 61 is laid immediately on rail beam 41, adjusts behind position and is fixed together by briquetting 8 and rail beam 41.Track 61 is generally laid to both sides by centre.Each section of track packs limiting plate 9 into after installing and adjusting to the right place, and the limiting plate 9 on single hop track when mounted, is all closely attached on orbital groove in the same direction, and by limiting plate welding and rail beam, 9 two of every section of equal limited location plates of track; Track straightness accuracy after installation, parallelism error need be in 5mm.
Above-described embodiment is only for the utility model of the present utility model design of explaining, but not restriction to the utility model rights protection, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should fall into protection domain of the present utility model.
