Abstract

The utility model relates to a simple arc bridge. Because the arch crown of a three-hinged arch is provided with hinges, the three-hinged arch has turning points when deforming and is disadvantageous to high-speed running; besides, because the structure of the crown hinges is complex, maintenance is inconvenient. Thus, the three-hinged arch is only suitable for steel arch bridges with a small span. The simple arc bridge comprises a supporting arch frame (1). A main support (2) is connected to the highest point of the supporting arch frame, and two auxiliary supports (3) support the supporting arch frame and are symmetrically arranged on the two sides of the main support. The top of the supporting arch frame is connected with an arched bridge floor (4), a guardrail (5) is arranged on the bridge floor, and the auxiliary supports are connected with the arched bridge floor. The simple arc bridge is used for road traffic.

Description

Simple and easy arch bridge
technical field:
the utility model relates to a kind of simple and easy arch bridge.
background technology:
most deck type or the half-through two hinged arch forms of adopting of arch bridge.Fixed-end arch, because there being firm ground, is restricted its range of application.Three hinged arch is hinged because of vault, has turning point during distortion, unfavorable to high speed traveling, and crown hinge complex structure, and inconvenient maintenance, therefore only for the steel arch bridge of less span.The arch rib of steel arch bridge generally can make truss-like, box-shaped or plate-girder shape, minute another name braced arch, case arch and plate arch.Arch bridge is divided into: Arch Bridge: the arch bridge that arch ring axis arranges by partial arc line.Advantage simple structure, building stones specification is minimum, gets the raw materials ready, setting-out, construction be all very easy; When shortcoming is load-bearing, encircleing internal pressure line, to depart from arch larger, discontinuity.Generally be applicable to the stone arch bridge that span is less than 20m.Arch bridges: the arch bridge that arch ring axis arranges is parabolically a kind of special case of catenary arch bridge.Advantage is that moment of flexure is little, and material is economized, and span ability is larger; Shortcoming be construct more complicated, if stone arch bridge the specification of work stone is more, construct more inconvenient.Catenary arch bridge: arch ring axis is pressed the arch bridge that catenary arranges.Advantage is stressed even, and moment of flexure is little, saves material.Be applicable to filled spandrel arch bridge more, in the spandrel-braced arched bridge of large span, also usually adopt this linear layout.
utility model content:
the purpose of this utility model is to provide a kind of simple and easy arch bridge.
the purpose of this utility model is achieved in that
a kind of simple and easy arch bridge, its composition comprises: scaffold, with main bearing, be connected to the peak of described scaffold, with the scaffold described in two secondary seat supports, secondary bearing described in two is symmetricly set on described main bearing both sides, the top of described scaffold is connected with arch bridge floor, and described bridge floor is provided with guardrail, and described secondary bearing is connected with described arch bridge floor.
described simple and easy arch bridge, in described main bearing and described secondary bearing, two parallel brace summers connect by one group of crossbearer, have fastening devices to reinforce between described crossbearer.
described simple and easy arch bridge, described scaffold and described main bearing, described secondary bearing are steel design.
beneficial effect:
1. can fully accomplish to gather materials on the spot, compare and can economize a large amount of steel and cement with beam bridge.
good endurance, and maintenance and maintenance cost few, and good looking appearance.
construct simpler, masonry arch bridge especially, technology is easily grasped, and is conducive to extensive employing.
accompanying drawing explanation:
accompanying drawing 1 is the utility model structural representation.
accompanying drawing 2 is structural representations of bracing frame of the present utility model.
accompanying drawing 3 is structural representations of main bearing of the present utility model.
accompanying drawing 4 is structural representations of the secondary bearing of the utility model.
the specific embodiment:
embodiment 1:
a kind of simple and easy arch bridge, its composition comprises: scaffold 1, with main bearing 2, be connected to the peak of described scaffold, with two secondary bearings 3, support described scaffold, secondary bearing described in two is symmetricly set on described main bearing both sides, the top of described scaffold is connected with arch bridge floor 4, and described bridge floor is provided with guardrail 5, and described secondary bearing is connected with described arch bridge floor.
embodiment 2:
according to the simple and easy arch bridge described in embodiment 1, in described main bearing and described secondary bearing, two parallel brace summers 8 connect by one group of crossbearer 6, have fastening devices 7 to reinforce between described crossbearer.
embodiment 3:
according to the simple and easy arch bridge described in embodiment 1, described scaffold and described main bearing, described secondary bearing are steel design.

Claims (1)

1. a kind of simple and easy arch bridge, its composition comprises: scaffold, it is characterized in that: the peak that is connected to described scaffold with main bearing, with the scaffold described in two secondary seat supports, secondary bearing described in two is symmetricly set on described main bearing both sides, the top of described scaffold is connected with arch bridge floor, described bridge floor is provided with guardrail, described secondary bearing is connected with described arch bridge floor, in described main bearing and described secondary bearing, two parallel brace summers connect by one group of dry crossbearer, between described crossbearer, there is fastening devices to reinforce, described scaffold and described main bearing, described secondary bearing is steel design.
