Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Referring to shown in Fig. 1 and Fig. 2, this utility model provides a kind of precast beam lifting positioner, and this device includes location sandbox 1, pre-embedded device 2 and regulates device 3.Wherein pre-embedded device 2 is fixed on bottom precast beam, and location sandbox 1 is fixed on by the bearing of pier coping portion.Regulate device 3 bottom the sandbox 1 of location and between bridge pier.
Referring also to shown in Fig. 3 and Fig. 4, pre-embedded device 2 is made up of a complete corrosion resistant plate, and it includes ball recess 21 and pre-embedded bolt 22.Pre-embedded bolt 22 and ball recess 21 firm welding, and ball recess 21 top is additionally provided with the detent 23 that direction of caving in ball recess 21 is consistent, detent 23 plays the effect of final location.During on-the-spot pre-buried pre-embedded device 2, need to determine in advance its accurate location and install firm.During casting concrete, vibrating spear must not vibrate ball recess 21, it is prevented that its deformation, affects precast beam locating effect.
Location sandbox 1 includes piston 11 and sleeve 12, and piston 11 is contained within sleeve 12.Referring to shown in Fig. 5 and Fig. 6, piston 11 includes the convex surface 111 matched with ball recess 21, and the shape profile of convex surface 111 and ball recess 21 match, and when precast beam para-position falls beam, precast beam can only by conducting oneself with dignity along convex surface 111 sliding.Being additionally provided with protruding 112 on convex surface 111, when precast beam sliding makes protruding 112 to be combined with detent 23, protruding 112 just complete location with detent 23.Referring to shown in Fig. 7 and Fig. 8, sleeve 12 one end is welded with base plate 121, it is provided with layer of sand bottom piston 11 and between base plate 121, sleeve 12 side is additionally provided with the device 122 that shakes out simultaneously, clearance hole 122a and the bolt 122b, clearance hole 122a being fixed on clearance hole 122a that the device 122 that shakes out includes being located at described sleeve 12 side is through hole.This utility model is provided with 4 clearance hole 122a and 4 matched bolt 122b.After turning on bolt 122b, along with sand flow goes out sleeve 12, piston 11 also declines therewith, so that precast beam slowly drops on bearing.
In order to facilitate the sliding of precast beam, first its medial surface can be polished smooth before ball recess 21 is installed, corresponding is before installing location sandbox 1, its convex surface 111 can also be polished, after polishing smooth, uniform application butter on convex surface 111, so that precast beam sliding is more convenient.
In addition in order to prevent from layer of sand from making moist affecting sand outflow, and then the whereabouts of precast beam is had influence on, it is possible to a certain amount of Colophonium is filled in the gap between piston 11 and sleeve 12.
Due to bottom precast beam to the distance of bridge pier end face not etc., in order to make the precast beam lifting positioner in this utility model have the suitability widely, adjustment device 3 can be set bottom the sandbox 1 of location and between bridge pier, regulate device 3 and include two lozenges bonded to each other, after adjustment device 3 is set, can very flexible height, adapt to different distances.
Utilize this precast beam lifting positioner to carry out precast beam lifting construction to mainly comprise the steps that
(1), after moulding board of precast beam is installed, groove type pre-embedded device 2, assembling reinforcement, casting concrete are installed in precast beam base plate precalculated position.
(2) beam location sandbox 2 is installed in pier top precalculated position, then convex surface 111 is polished smooth, and uniform application butter.Location sandbox 2 need to guarantee horizontal positioned, and fixing preventing is moved simultaneously.
(3) the hoisting prefabricated beam of hanging device is to beam position place, and slow para-position falls beam.By the position of precast beam is adjusted roughly, making protruding 112 in pre-embedded device at the bottom of beam 2 scope, hanging apparatus slowly falls beam, precast beam under Gravitative Loads automatic sliding to positioner precalculated position.
(4) keeping hanging apparatus motionless, sandbox clearance hole 122a is opened after having confirmed that precast beam position is errorless in scene, and precast beam slowly falls on bearing.
(5), after treating that large-scale precast beam drop on bearing, after reaffirming that its position is errorless, location sandbox 2 is removed from pier location, checks and can be continuing with without after damaging.
(6) precast beam base plate precalculated position installation groove scene concrete is floating, recovers large-scale precast beam outward appearance.
Precast beam of the present utility model lifting positioner by arranging ball recess 21 bottom precast beam, simultaneously at bridge pier correspondence position stationary positioned sandbox 1, location sandbox 1 includes piston 11 and sleeve 12, is provided with the convex surface 111 matched with ball recess 21 on piston 11.Ball recess 21 top is provided with detent 23, and corresponding is arrange protruding 112 on the piston 11 of location sandbox 1.After precast beam para-position falls beam, precast beam will at automatic sliding under Gravitative Loads, if now protruding 112 being not in detent 23, then the support force of precast beam can be made precast beam towards protruding 112 direction slidings by the gravity of precast beam and protruding 112 with joint efforts, until protruding 112 are combined with detent 23, it is finally completed the location of precast beam.Namely whole hoisting process need not arrange large-scale jack, and precast beam at exactitude position under Gravitative Loads, can eliminate loaded down with trivial details adjustment of displacement process, thus having saved the duration.
This utility model is not limited to above-mentioned embodiment; for those skilled in the art; under the premise without departing from this utility model principle, it is also possible to make some improvements and modifications, these improvements and modifications are also considered as within protection domain of the present utility model.The content not being described in detail in this specification belongs to the known prior art of professional and technical personnel in the field.
