Abstract
The utility model discloses a reinforced concrete pier in the two-lane multi-span beam type bridge cross-linking position of a small and medium sidewalk, which consists of a horizontal platform, two vertical platforms and a plurality of suspended binding beams. The horizontal platform, the two vertical platforms, and the suspended binding beams which are connected with the two ends of the two vertical platforms and arranged in an upper row and a lower row form a Chinese character Zhong (middle in English) overlooking planar graph structure. The utility model is applicable to the bridge pier for bearing one 120-ton trailer or two ordinary load vehicles, with the bridge width being 5.8 meters, the bridge span being 20 to 30 meters and the total span more than or equal to 100. Compared with the conventional square or rectangular pier, the utility model can save the concrete by 49.7 percent and reduce the manufacturing cost by 35 to 40 percent.
Description
Technical field:
The present invention relates to the civil construction field, relate in particular to and a kind ofly be adapted to 20～30 meters in single span footpath, always stride footpath two-lane multispan beam type bridge span connection reinforced concrete pier in the middle-size and small-size sidewalk more than 100 meters.
Background technology:
Along with rapid economic development, people and logistics increase severely, speedway, Class I highway, Class II highway has become network design and has built construction, institute's highway of building also occur to be crossed over the shallow ridges valley through regular meeting, thereby need establish the bridge construction beam so that highway is freely without hindrance, and the beam bridge bridge of the expert single vehicle in this sidewalk is generally single span footpath 20m～30m, always strides footpath＞100m; The bridge pier pier structure design of this bridge is four directions or cuboid bridge pier at present, the inventor finds that by site investigation this bridge pier pier is durable, is suitable for earthquake-prone region, but for some relatively stable areas, the construction of this bridge pier pier can cause the waste of material such as reinforcing bar, cement.
Summary of the invention:
In order to overcome the waste that causes under construction of present Bridge Pier structure, the purpose of this invention is to provide a kind of stability requirement that can satisfy the coefficient of stability that holds bridge load, can save two-lane multispan beam type bridge span connection reinforced concrete pier in the raw-material middle-size and small-size sidewalk again, the design and construction of this pier will be tied province's raw material in a large number, reduce the gross investment of bridge construction.
Technical scheme of the present invention realizes in the following manner:
Two-lane multispan beam type bridge span connection reinforced concrete pier in a kind of middle-size and small-size sidewalk, it is made up of a Heng Tai, two perpendicular platforms, several outstanding binding beams, wherein Heng Tai and two perpendicular platforms and with being connected two perpendicular platform two ends several outstanding binding beams in a row up and down form one " in " the top plan view figure structure of font.
Described two-lane multispan beam type bridge bridge reinforcement concrete pier single span footpath l=20m～30m, horizontal platform length (a) be bridge wide 80%; Perpendicular platform length (l) is 1/8 meter of height, when perpendicular platform height during, perpendicular platform width c=0.80 rice at 15 meters, and, perpendicular platform height subtracts 1 meter downwards, erects the platform width and subtracts 0.002 meter; Horizontal platform width e=0.40 meter, when horizontal platform height subtracted 1 meter downwards, horizontal platform width subtracted 0.005, and the distances between Heng Tai and the two perpendicular platform center intersection points are g=2.60 rice, and horizontal platform convex goes out length d=0.63 meter; Outstanding up and down binding beam distance between center line is 5 meters, and outstanding binding beam is rectangular build, its width=height h=0.24～0.392 meter.
When perpendicular platform height was 15-32 rice, apart from being 3 meters so that play balanced action, the outstanding binding beam length of described outstanding binding beam width=height h=1/4 was erected 1 meter of the every increase of platform height to outstanding binding beam between the upper and lower, and described perpendicular platform width increases by 0.002 meter; 1 meter of the every increase of horizontal platform height, described horizontal platform width increases by 0.005 meter.
The present invention is applicable to that one of 120 tons of Pallet Truck of feasible load-carrying or two bridges of conventional truck wide are 20 meters-30 meters of 5.8 meters, spanning footpath, the Bridge Pier of total span 〉=100, compare with the tetragonal body or the cuboid pier of routine, can save about 49.7% concrete consumption, can save cost 35-40%.
Description of drawings:
Fig. 1 is a plan structure schematic diagram of the present invention.
Fig. 2 is a main TV structure schematic diagram of the present invention.
Fig. 3 is the main TV structure schematic diagram of 32 meters high pier piers.
The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing:
Embodiment one:
As seen from Figure 1: it be wide with bridge be 5.8 meters, the pier height is that 15 meters standard designs, it is made up of the perpendicular platform of a horizontal platform 1, two 2, three outstanding binding beams 3, the perpendicular platform 2 of wherein horizontal platform 1 and two and with being connected two perpendicular platform two ends three outstanding binding beams 3 in a row up and down form one " in " the top plan view figure structure of font, as seen from Figure 2, described reinforced concrete pier, three distances of hanging between the binding beam center line up and down are 5 meters; It can also be seen that by Fig. 1: horizontal platform length a=4.64 rice; Perpendicular platform length l=1.875 rice, perpendicular platform width c=0.8 rice, horizontal platform width e=0.4 meter, Heng Tai is a g=2.6 rice with two distances of erecting between the intersection points of platform center, horizontal platform convex goes out length d=0.63 meter; Outstanding binding beam is rectangular build, (h)=0.24 of its width=highly meter.
Embodiment two:
As seen from Figure 3: it be wide with bridge be 5.8 meters, the pier height is that 32 meters standard designs, described reinforced concrete pier has 11 outstanding binding beams, the distance between ten binding beam center lines from bottom to top is 3 meters; Between the adjacent outstanding binding beam center line of the outstanding binding beam center line of the top with the below apart from 3 meters of less thaies, be it can also be seen that by Fig. 1: perpendicular platform width is 0.834 meter, 0.485 meter of horizontal platform width, and perpendicular platform length is 4 meters, outstanding binding beam is rectangular build, (h)=0.392 of its width=highly meter.
