Description
Technical field
The utility model relates to strides the closure segment construction equipment in a kind of, strides the suspension apparatus of closure segment Hanging Basket in particularly a kind of.
Background technology
In the field of bridge construction, cast-in-place cantilever method is claimed no support balance semi-girder method or extension (hanging) basket method again, refers in the bridge pier both sides working platform is set, and evenly piecemeal to span centre cantilever pouring cement concrete beam body, and applies prestressed job practices piecemeal.Used main equipment is Hanging Basket, and the member of Hanging Basket mainly comprises: truss, suspension system, walking system, template and stretch-draw platform five major parts, it is following to adopt Hanging Basket to carry out the operating principle of cantilever pouring: bed die, outer side form with triangular truss move forward in place after; Colligation base plate, web reinforcement and prestressed pipeline, with interior mould bases move in place after, inner formword is installed; Colligation top board reinforcing bar and prestressed corrugated conduit; Carry out beam section cantilever pouring construction, after newly watering beam section stretch-draw anchor and hole path pressure grouting, the Hanging Basket next beam section construction of carrying out in place that moves forward again; So circulation is passed, until the construction of accomplishing last beam section.
Wherein, suspender belt and back strap and lifting appliance before the suspension system of Hanging Basket comprises, its effect is that a weight concrete and a template weight part that cantilever pours into are reached on the main couple.Preceding suspender belt is made by 4 steel plates usually, and a part of Load Transfer that the effect of back strap is Hanging Basket is born is to case beam base plate, and back strap is processed by 2 steel plates usually; Interior mould bases is suspended in two internal molds through suspension apparatus and walks on the cross girders, walks the cross girders front end and is hung on the truss front beam, and the rear end is hung on the casting beams section preformed hole; Interior mould bases can slide along walking cross girders, and template all adopts combined steel, behind interior moulding/demoulding; Internal mold drops on internal mold and walks on the cross girders; Promote with artificial, can internal mold be moved to next section beam, finally after the closure segment construction is accomplished, remove Hanging Basket.
But still there is following weak point in it: because suspender belt is not dismantled before building; Build in the process; Concrete can condense on the locating hole of suspender belt; When building when accomplishing back strap and needing the demoulding, the concrete after solidifying during the big and demoulding of demoulding difficulty is prone to suspender belt is caused wearing and tearing, is unfavorable for the repeated use of suspender belt.
The utility model content
The technical problem that the utility model will solve is to overcome the above-mentioned deficiency of prior art, provide a kind of when being easy to the demoulding and the demoulding to the suspender belt damage little in stride the suspension apparatus of closure segment Hanging Basket.
For solving the problems of the technologies described above; The utility model provides following technical scheme: the suspension apparatus of striding the closure segment Hanging Basket in a kind of; Comprise suspender belt and the suspension rod that is used for fixing suspender belt; Said suspender belt is provided with sleeve, and said suspender belt is arranged on sleeve inner, and the cavity shape of said sleeve and the profile of suspender belt are suitable.
Through the suitable with it sleeve of peripheral suit shape at suspender belt; Avoided the case beam when building, suspender belt directly contacts with concrete, the situation of having avoided the concrete setting back strap to be difficult to take out; Make suspender belt be convenient to the demoulding, and can avoid because of directly contacting the damage that produces during the demoulding with concrete.
Stride in above-mentioned in the suspension apparatus of closure segment Hanging Basket, said suspender belt comprises preceding suspender belt, and the two ends of said preceding suspender belt connect with the Hanging Basket bed die with top rail respectively.Adopt above-mentioned structure, preceding top rail is linked to each other with Hanging Basket bed die front end, not only increased the intensity that connects, avoid building the situation that back strap is difficult to the demoulding through sleeve simultaneously through suspender belt.
Preferably, said sleeve set is on preceding suspender belt, and said sleeve is arranged between top rail and the Hanging Basket bed die.Adopt such structure, the zone before sleeve is arranged between top rail and the Hanging Basket bed die is arranged on suspender belt with sleeve and contacts with concrete on the concrete body, and all the other suspender belt that does not contact with concrete body parts need not be provided with sleeve.
Preferably, said suspender belt also comprises back strap, and the two ends of said back strap are connected with the Hanging Basket bed die with case beam bottom respectively.Link to each other through the main couple of suspender belt, not only increased the intensity that connects, avoid building the situation that back strap is difficult to the demoulding through sleeve simultaneously case beam bottom and Hanging Basket.
Preferably, said sleeve set is on back strap, and said sleeve is arranged between the main couple of case beam bottom and Hanging Basket.Adopt such structure, sleeve is arranged on the zone between the main couple of case beam bottom and Hanging Basket, sleeve is arranged on suspender belt contacts with concrete on the concrete body, all the other suspender belts that do not contact with the concrete body partly need not be provided with sleeve.
Stride in above-mentioned in the suspension apparatus of closure segment Hanging Basket, be provided with connecting rod between said sleeve and the suspender belt, said suspender belt is fixedly installed on the inner chamber middle part of sleeve through connecting rod.Adopt such structure, when setting up sleeve, utilize connecting rod that sleeve is connected on the suspender belt, and be embedded in case beam inside synchronously with suspender belt, when installation and removal, suspender belt does not directly contact with concrete in the location.
Preferably, said connecting rod two ends respectively with sleeve and suspender belt welding.When needs are removed suspender belt and sleeve, only need to weld releasing, can remove suspender belt and sleeve successively, have the beneficial effect of connection, easy accessibility.
Stride in above-mentioned in the suspension apparatus of closure segment Hanging Basket, said sleeve is that the steel plate of 3mm is welded by thickness.Adopt such structure, the steel plate of 3mm is seen everywhere at the construction field (site), can carry out second use to the discarded parts of job site.
In sum, owing to adopted technique scheme, compared with prior art; The beneficial effect of the utility model is: through the suitable with it sleeve of peripheral suit shape at suspender belt; Avoided the case beam when building, suspender belt directly contacts with concrete, the situation of having avoided the concrete setting back strap to be difficult to take out; Make suspender belt be convenient to the demoulding, and can avoid because of directly contacting the damage that produces during the demoulding with concrete.
