Abstract
The utility model discloses an assembled arch rib which comprises a top flange, a left web, a right web and a bottom flange. The top flange and the bottom flange are arranged in parallel, and the left web and the right web are symmetrically arranged between the top flange and the bottom flange. An inverted trapezoidal box type section is formed by the structure. The top flange and the bottom flange are rectangular hollow steel pipes and are filled with concrete. A vertical stiffening rib is arranged in a cavity of the top flange, and the left web and the right web are wave-shaped thin-wall steel plates which are arranged in the length direction. According to the assembled arch rib, the rectangular steel pipes are filled with the concrete to replace conventional reinforced concrete slabs, and the stressed performance is good. Thin-walled cold-formed steel is used for replacing conventional steel or concrete webs, and shearing resistance is high. The assembled arch rib is good in stress, low in cost, good in integrity, convenient to produce and transport, high in assembling speed, short in construction period, low in construction cost and obvious in social benefit and economic benefit.
Description
Technical field
The utility model relates to a kind of prefabricated assembled arch rib, belongs to bridge new type of component field.
Background technology
Arch bridge is because it has graceful linear and good load-carrying properties, and in the city of water system prosperity, application is very general.Along with the increase of urban traffic amount, road pressure is large, administrative department often wish to build durations of road and bridge more short better, cost is more low better.Conventional concrete arch-type bridge is to set up at the scene support, then concreting on support, and health concrete arrives enough intensity next step operation of could constructing, engineering time is long, and concrete gravity is large, high to the bridge foundation requirement of two sides, construction cost is high.Steel arch bridge speed of application is fast, but steel using amount is large, cost is high.Therefore, assembled steel-Combined concrete formula arch bridge will be the new selection of bridge Fast Construction.
Summary of the invention
The purpose of this utility model is to provide a kind of assembling arch rib, and it can replace traditional concrete arch rib or steel arch rib, compares that the deadweight of traditional arch rib is lighter, cost is lower, speed of application is fast, is particularly suitable for the fast construction of city arch bridge.
In order to address the above problem, the technical solution adopted in the utility model is: a kind of assembling arch rib, comprises top flange, left web, right web and bottom flange; Described top flange and bottom flange be arranged in parallel, and between top flange and bottom flange, are symmetrically arranged with left web and right web, and the cross section of the arch rib being made up of said structure is box-type section.
As further improvement of the utility model, described top flange and bottom flange are rectangle hollow steel pipe, and filler is housed in hollow steel pipe; Described left web and right web are that even or inhomogeneous periodicity repeats the waveform thin-walled steel plate arranging along its length.
As further improvement of the utility model, described filler is high-strength concrete or the contour performance concrete of steel fibrous concrete, in described top flange and the hollow steel pipe of bottom flange, is vertically provided with stiffening rib, increases local anti-pressure ability.
As further improvement of the utility model, described left and right web is vertically set on respectively between the upper and lower edge of a wing.
As further improvement of the utility model, the described box-type section being made up of the upper and lower edge of a wing and left and right web is inverted ladder type, and the angle of left and right web and bottom flange is 90 °～140 °.
As further improvement of the utility model, described left and right web is welded on respectively between the upper and lower edge of a wing.
As further improvement of the utility model, the ripple section of described waveform thin-walled steel plate is circular arc waveform or sinusoidal or trapezoidal waveform.
The beneficial effects of the utility model are: not only practicality but also economy that the utility model is built in order to realize arch bridge, propose a kind of steel-concrete combined type box arch rib.Replace conventional armored concrete slab with rectangular steel pipe concrete filled, Compressive Performance is good; Replace conventional steel or concrete web with clod wash waveform thin-walled steel plate, shearing resistance is large.The arch rib stress performance of this type is good, and from heavy and light, cost is low; Meanwhile, this kind of member, in plant produced, is transported to scene directly assembled, and speed is fast, and the duration is short, also greatly reduces operating expenses, has obvious Social benefit and economic benefit.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 to Figure 2, a kind of assembling arch rib, comprises top flange 1, left web 2, right web 3 and bottom flange 4; Described top flange 1 be arranged in parallel with bottom flange 4, and between top flange 1 and bottom flange 4, be symmetrically arranged with left web 2 and right web 3, described left web 2 and right web 3 are welded between top flange 1 and bottom flange 4, and the cross section of the arch rib being made up of said structure is box-type section.
Described top flange 1 is rectangle hollow steel pipe with bottom flange 4, and high-strength concrete or the contour performance concrete of steel fibrous concrete are housed in hollow steel pipe, in the hollow steel pipe of top flange 1 and bottom flange 4, is vertically provided with stiffening rib 6, increases local anti-pressure ability; Described left web 2 is that even or inhomogeneous periodicity repeats the waveform thin-walled steel plate arranging along its length with right web 3, and the ripple section of described waveform thin-walled steel plate can be arc-wave shape or sinusoidal or trapezoidal waveform.
Described left web 2 and right web 3 are vertically set on respectively between top flange 1 and bottom flange 4.
The described box-type section being made up of top flange 1, bottom flange 4, left web 2 and right web 3 is inverted ladder type, and left web 2 and right web 3 be preferably 120 ° with the angle of bottom flange 4, certainly as long as it is all fine between 90 °～140 °.
In the building course of arch bridge, between every two box arch ribs, link together by arch springing place end plate 5 respectively, form a bridge arch rib.
This assembling arch rib replaces conventional armored concrete slab with rectangular steel pipe concrete filled, and Compressive Performance is good; Replace conventional steel or concrete web with clod wash waveform thin-walled steel plate, shearing resistance is large.The arch rib stress performance of this type is good, and from heavy and light, cost is low; Meanwhile, this kind of member, in plant produced, is transported to scene directly assembled, and speed is fast, and the duration is short, also greatly reduces operating expenses, has obvious Social benefit and economic benefit.
