Abstract

The utility model belongs to the field of municipal bridge design, in particular to a pedestrian overcrossing assembling type steel truss girder. The pedestrian overcrossing assembling type steel truss girder comprises a top frame, an overcrossing road bottom frame serving as an overcrossing road and trusses which are located on two sides of the overcrossing road and serves as guardrails. The top frame, the overcrossing road bottom frame and the trusses form a cuboid frame over a road. Main support columns are disposed on two sides of the cuboid frame. The trusses, the top frame and the overcrossing road bottom frame are made of circular steel pipes or square steel pipes sleeving through bushes. The girder is convenient to manufacture, convenient in hoisting in position, short in construction cycle, and can be used for a simply-supported pedestrian overcrossing with large span. Due to the fact that the girder is of a through structure, the length of a bridge staircase is unaffected by the span and the height of the girder.

Description

A kind of pedestrian overcrossing assembled steel truss girder
Technical field
The utility model belongs to municipal bridge design field, relates in particular to a kind of pedestrian overcrossing assembled steel truss girder.
Background technology
At present, all material is transported to construction ground by design and the structural requirement of overline bridge, a large amount of work high above the ground, open work, and the cycle of carrying out is long, affect the walking of normal pedestrian and vehicle, especially the in the situation that of bad weather, affect the progress of engineering, in addition, the structure of existing overline bridge is in the time of crossbearer road, for wider span, unreasonable due to structure, cannot complete wider span.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of pedestrian overcrossing assembled steel truss girder, is intended to solve overline bridge long construction period outside in prior art, the problem poor compared with the load-carrying members of large span.
The utility model is to realize like this, a kind of pedestrian overcrossing assembled steel truss girder, comprise upper frame, bridge road underframe is as bridge road and be positioned at the truss of Qiao Dao both sides as guardrail, upper frame, bridge road underframe and truss composition are across the cuboid framework of road, main support column is set in the both sides of cuboid framework to be supported, wherein, truss comprises the truss framework of surrounding, truss framework is that multiple square steel pipes are formed by connecting by framework truss sleeve pipe, in truss framework, be provided with " ^ " ellbeam, described " ^ " ellbeam is formed by connecting by sleeve pipe between " ^ " ellbeam by multiple round steel pipe, all fix by the C type floor of putting more energy in the junction of " ^ " ellbeam and truss framework.
Further, described bridge road underframe comprises bridge road frame-saw frame, and the multiple tracks bridge road frame crossbeam evenly arranging in Qiao road frame-saw frame; Described upper frame comprises upper frame framework, and the multiple tracks upper frame crossbeam arranging in upper frame framework, between its jackshaft road frame crossbeam, is set to 1/2~1/3 of interval between upper frame crossbeam.
Further, bridge road frame-saw frame is socketed to form by multiple square steel pipes, and bridge road frame crossbeam adopts round steel pipe.
Further, upper frame framework is socketed to form by multiple square steel pipes, and upper frame crossbeam adopts round steel pipe.
Compared with prior art, beneficial effect is the utility model: fabricated construction is the building forming at assemble in site with prefabricated member.A large amount of work high above the ground, open work are completed as far as possible in ground, factory.Construction speed is fast, and climate conditionality is little, and when construction, traffic is disturbed littlely, saves labour can improve construction quality, guarantees safe construction.Greatly develop modern architecture industry to reducing energy consumption cost, improving building structure quality and construction efficiency.
Under load action, truss mainly bears axial tension or pressure, thereby can make full use of the intensity of material, is applicable to the load-carrying members compared with large span.
The advantage of trussed construction is easy to make, be convenient to hoisted in position, can do the freely-supported pedestrian overcrossing across footpath greatly, and because girder is lower support type structure, the length of bridge ladder is the impact of acceptor's girder span footpath and deck-molding not, no matter how to change across footpath and deck-molding, in the situation that under-clearance standard is unified, the length of bridge ladder is all identical.So, it is greatly convenient to have brought to the batch production of bridge ladder, and can realize veritably standardized designs.
