Abstract
The utility model discloses a bracket for deepwater single-pile single-column-pier concrete box-girder 0#block construction. The bracket comprises a bracket support, a hoop platform, bracket columns and a 0#block concreting construction platform. The bracket support comprises an annular steel plate fixed at the outer circumference of a deepwater single-pile single-column-pier main-body foundation steel casing, and multiple vertical stiffening plates which are uniformly distributed around the main-body foundation steel casing. The hoop platform comprises sleeves which are sleeved out of deepwater single-pile single-column piers, and a rectangular frame sleeved out of the sleeves. The lower ends of the sleeves are uniformly provided with multiple hinged supporters along the circumferential direction. The rectangular frame is hinged with the hinged supporters via multiple oblique supporting poles. The hoop platform is formed by assembling two half bodies which are equally separated along the axial direction. The bracket columns are fixed on a top surface of the hoop platform. The 0#block concreting construction platform is fixed on top surfaces of the bracket columns. The utility model solves the problem of difficult deepwater single-pile single-column-pier concrete box-girder 0#block construction.
Description
Technical field
The utility model relates to concrete box girder 0# piece construction equipment, the support of the only stub concrete box girder of the deep water single pile 0# piece that is specifically related to be used to construct.
Background technology
When adopting symmetrical cantilever construction concrete box girder, primary task is to carry out building of concrete box girder 0# piece, and the conventional construction method of concreting case beam 0# piece mainly contains following several kinds:
(1) uses the bowl fastening type support to act on to handle and have on the ground of certain bearing capacity;
(2) use the large diameter steel pipe column holder to act on the cushion cap;
(3) arrange that triangle falsework structure is connected with the pre-buried steel structure.
But for the concrete box girder of the only stub of deep water single pile, above-mentioned three kinds of traditional job practicess all receive certain restriction.Specifically, because the substructure of the only stub concrete box girder of deep water single pile is a pile formula structure, the large diameter steel pipe column holder can't use; And basic residing deepwater regions does not possess the condition of setting up the bowl fastening type support; In addition, built-in fitting is set needs reserving hole or pre-buried steel structure on the bridge pier post, cause bridge pier post construction inconvenience, and if the built-in fitting position deal with improperly and not only influence the main body outward appearance even can influence its durability.Especially coastal waters or the Oversea bridge to being positioned at three types of environment generally do not advocated or forbidden being provided with embedded part structure and construct, in order to avoid influence the durability of this type of bridge.
This shows that the job practices of traditional concreting case beam 0# piece is not suitable for the concrete box girder of the only stub of deep water single pile, causes the concrete box girder 0# piece constructional difficulties of the only stub of deep water single pile.
The utility model content
The utility model technical problem to be solved is the problem that solves the concrete box girder 0# piece constructional difficulties of the only stub of deep water single pile.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted provides a kind of support of the only stub concrete box girder of the deep water single pile 0# piece that is used to construct, and comprising:
Stent support; Comprise the doughnut-shaped steel plate on the subjective basis steel casing outer circumference surface that is fixed on the only stub of deep water single pile and be distributed on subjective basis steel casing a plurality of vertical stiffener on every side, said vertical stiffener is fixed with the bottom surface of said doughnut-shaped steel plate and the external peripheral surface of subjective basis steel casing respectively;
The anchor ear platform; Comprise and be set in the outer sleeve of the only stub of deep water single pile and be set in the outer rectangular frame of said sleeve; The upper end of said sleeve is fixed with the horizontal loops ellbeam, and lower end edge circumferentially is uniformly distributed with a plurality of free bearings are set, and is connected fixing between said horizontal loops ellbeam and the said rectangular frame through many horizon bars; Said rectangular frame is hinged through many hounds and said free bearing, and said anchor ear platform is assembled by the halved body of dividing equally vertically;
Bracket upright post, truss structure is fixed on the end face of said anchor ear platform;
0# block concrete pouring construction platform is fixed on the end face of said bracket upright post.
At the support of the above-mentioned only stub concrete box girder of the deep water single pile 0# piece that is used for constructing, said 0# block concrete pouring construction platform is assembled to distribution beam, direction across bridge distribution beam, Bei Leiliang and case soffit distribution beam by many vertical bridges from bottom to top successively.
The utility model provides, and be used for the constructing support of the only stub concrete box girder of deep water single pile 0# piece satisfies the big load force request of 0# piece work progress; And convenient and quick construction, thereby solved the problem of the concrete box girder 0# piece constructional difficulties of the only stub of deep water single pile.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is made detailed explanation.
As shown in Figure 1, the utility model provides be used to the to construct support of the only stub concrete box girder of deep water single pile 0# piece comprises stent support 2, anchor ear platform 3, bracket upright post 4 and 0# block concrete pouring construction platform from the bottom to top successively.
The structure of stent support 2 such as Fig. 2, shown in Figure 3; Comprise the doughnut-shaped steel plate 12 on subjective basis steel casing 1 outer circumference surface that is fixed on the only stub of deep water single pile and be distributed on subjective basis steel casing 1 a plurality of vertical stiffener 11 on every side, vertical stiffener 11 is fixed with the bottom surface of doughnut-shaped steel plate 12 and the external peripheral surface of subjective basis steel casing 1 respectively.Vertical stiffener 11 carries out the part with 12 pairs of supports of doughnut-shaped steel plate and strengthens, and forms the support of support, and auger shell keyhole on doughnut-shaped steel plate 12 is prepared against and anchor ear platform 3 bolts.
The structure of anchor ear platform 3 such as Fig. 4, Fig. 5, shown in Figure 6; Comprise being set in the outer sleeve 31 of the only stub of deep water single pile and being set in the rectangular frame 32 outside the sleeve 31 that the upper end of sleeve 31 is fixed with horizontal loops ellbeam 33, lower end edge circumferentially is uniformly distributed with a plurality of free bearings 34 is set; Be connected fixing between horizontal loops ellbeam 33 and the rectangular frame 32 through many horizon bars 35; Rectangular frame 32 is hinged through many hounds 36 and free bearing 34, and anchor ear platform 3 is assembled by the halved body of dividing equally vertically, and general halved body part is in factory process; Connect into whole anchor ear platform 3 with the M30 high-strength bolt during construction, more convenient.
