Abstract
The invention discloses a buckling and hanging system for an outwards inclined steel box arch rib, which is characterized in that a fixed end of a buckle cable (2) is arranged on an arch rib segment (7), and a stretching end of the buckle cable (2) is arranged on an anchor beam of a cable support tower (1); an anchor rope (3) is connected between the anchor beam of the cable support tower (1) and an anchor beam alley (4); and a temporary cross-link (5) is connected between two corresponding arch rib segments. In the system, the buckle cable balances a vertical force component generated by the self weight of the arch rib; the temporary cross-link balances a transverse force component of the outwards inclined arch rib; lateral cable wind balances a transverse force generated by external factors (wind); and the arch rib keeps balanced through the three-dimensional buckling and hanging system and self rigidity of the arch rib, and linear design is achieved. Moreover, the mutual balance between two arch ribs is fully utilized to solve the transverse imbalanced force caused by outward inclination during construction. Therefore, construction of the arch rib is carried out smoothly, installation is accurate, and difficulty of positioning and mounting the arch ribs without cross connection is solved.
Description
Technical field
The present invention relates to construction equipment, especially relating to a kind of external inclined type does not have outward inclined steel box arch rib buckling and hanging system in the horizontal connection steel box arch rib work progress.
Background technology
Existing button mounts and is equipped with vertical parallel arch rib buckling and hanging device and introversion formula arch rib buckling and hanging device, and these two kinds devices are all because of there being cross binding need not consider the influence of dead load in the direction across bridge direction between arch rib.External inclined type does not have and has the problem that dead load direction across bridge component need balance in the horizontal connection arch rib work progress, more than two kinds of buttons mount and put all and can not meet the demands.
Summary of the invention
The object of the invention provides in a kind of assurance arch rib work progress and keeps self balance, and guarantee the linear outward inclined steel box arch rib buckling and hanging system of arch rib design, solving external inclined type does not have and has dead load and environmental activity equilibrium of forces problem in the horizontal connection arch rib work progress.
In order to achieve the above object, the present invention adopts following technical scheme: a kind of outward inclined steel box arch rib buckling and hanging system, the fixed end of knotted rope is arranged on the rib-lifting section, the stretch-draw end is arranged on the Sarasota anchor beam, be connected with anchor cable between Sarasota anchor beam and the anchor cable alley, the anchor cable fixed end is positioned on the alley, knotted rope stretch-draw end is arranged on the anchor beam of Sarasota, horizontal component by anchor beam balance button anchor cable (knotted rope and anchor cable), and the vertical force component that will detain anchor cable passes to Sarasota, is connected with interim horizontal-associate between corresponding two rib-lifting sections.
Described rib-lifting section is fixed on the alley through the side guy.
The present invention is the buckling and hanging system in a kind of arch rib work progress, and this system carries out balance to rib-lifting section component makes the horizontal arch rib that connects of nothing position installation smoothly.For realizing the smooth location and installation of arch rib, the external inclined type arch rib must guarantee after lifting puts in place under a stress balance state, stress balance in the arch rib work progress is by button anchor cable system, the common arch rib buckling and hanging system of forming of interim horizontal-associate and side guy is finished, wherein detain the anchor cable system by knotted rope, anchor cable, Sarasota and alley are formed, mainly the vertical force component that deadweight produces to arch rib is carried out balance, interim horizontal-associate carries out balance to the component of walking crosswise of external inclined type arch rib, the side guy horizontal force of factor (wind) generation to external world carries out balance, and the effect of three directions adds that the rigidity of arch rib self makes arch rib keep balance.
Advantage of the present invention: the knotted rope among the present invention etc. can carry out balance to the vertical force component that the arch rib deadweight produces, interim horizontal-associate carries out balance to the component of walking crosswise of external inclined type arch rib, the side guy horizontal force of factor (wind) generation to external world carries out balance, effect by three directions of buckling and hanging system adds that the rigidity of arch rib self makes arch rib keep balance, and it is linear to reach design, but also the mutual balance that makes full use of two arch ribs solves the horizontal out-of-balance force that brings because of flare in the work progress, the arch rib construction is carried out smoothly, be in place, having solved does not have the problem that laterally connects arch rib location and installation difficulty.
Description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the structural representation of the Sarasota 1 among the present invention.
The specific embodiment
Below in conjunction with drawings and Examples buckling and hanging system is further described.
A kind of outward inclined steel box arch rib buckling and hanging system of the present invention is seen Fig. 1, Fig. 2, shown in Figure 3, mainly is made of Sarasota 1, knotted rope 2, anchor cable 3, anchor cable alley 4, interim horizontal-associate 5, side guy 6, and Sarasota is as the vertical applied force structure.Wherein the fixed end of knotted rope 2 is positioned on the rib-lifting section 7, the stretch-draw end is on the anchor beam of Sarasota 1, be connected with anchor cable 3 between the anchor beam of Sarasota 1 and the anchor cable alley 4, anchor cable 3 fixed ends are positioned on the alley 4, the stretch-draw end of knotted rope 2 is arranged on the anchor beam 8 of Sarasota, by the horizontal component of anchor beam balance button anchor cable (knotted rope and anchor cable), and the vertical force component that will detain anchor cable passes to Sarasota, is connected with interim horizontal-associate 5 between corresponding two rib-lifting sections.Described rib-lifting section 7 is fixed on the alley through side guy 6.In Fig. 1, the rib-lifting section 7 that is camber line is corresponding in twos.
Buckling and hanging system work is as follows: after at first rib-lifting section 7 liftings in upstream being put in place, this sections knotted rope 2 of synchronous tension, anchor cable 3, then corresponding downstream rib-lifting section 7 is lifted and put in place, stretch-draw knotted rope 2, anchor cable 3 are finished the interim horizontal-associate 5 of post tensioning two intercostals in the welding of two rib-lifting sections; So repeatedly rib-lifting section is lifted stretch-draw side guy 6 when the arch rib jib-length reaches certain-length.Nanning, Nanning City bridge master bridge is an asymmetry outward inclined steel arch bridge, does not establish horizontal-associate between two arch ribs.Bridge adopts the cable hanging apparatus to carry out erection without scaffolding, and this button of application mounts and puts in the hoisting engineering, and the rib-lifting section lifting construction is finished smoothly, and has reached the linear requirement of design.
Claims (2)
1, a kind of outward inclined steel box arch rib buckling and hanging system, it is characterized in that: knotted rope (2) fixed end is on rib-lifting section (7), the stretch-draw end is on Sarasota (1) anchor beam, be connected with anchor cable (3) on the anchor beam of Sarasota (1) and between the anchor cable alley (4), between corresponding two rib-lifting sections, be connected with interim horizontal-associate (5).
