Abstract
The utility model relates to a combined connecting structure of corrugated steel web plates in a box beam bridge, which mainly solves the technical problems of difficult hole operation or difficult welding operation and the like during the connection of the existing corrugated steel web plates. The combined connecting structure comprises two corrugated steel web plates; the connecting ends of the corrugated steel web plates are provided with corresponding bolt holes; the connecting ends of the two corrugated steel web plates are connected through ordinary bolts; and another corrugated steel web plate is welded at a port of each connecting end. The combined connecting structure uses the ordinary bolts for temporary fixation on the corrugated steel web plates, provides stable supporting and fixing effects for in-site welding, ensures the welding quality, reduces the internal stress caused by construction, and is favorable for cost reduction.
Description
Technical field
The utility model relates to combined box beam member connection structure in the large-span continuous girder bridges, is specially Wavelike steel webplate joint construction in a kind of corrugated steel web plate composite box girder bridge.
Background technology
Wavelike steel webplate in the existing bridge in the waveform steel web box girder is at the segmented processing and fabricating that carries out of factory, when construction, each sections Wavelike steel webplate of processing is transported to the job site, and along with the casting process of concrete floor, top board in the case beam with each sections connection successively.Connection between the existing steel web mainly contains following several form of structure (referring to Fig. 1): the friction of (1), high-strength bolt single face connects.Referring to Fig. 1 a, the two ends that Wavelike steel webplate 1` is connected overlap, and directly connect with high-strength bolt 2` then.(2), the friction of knuckle single face connects.Referring to Fig. 1 b, weld or directly be processed into a knuckle junction plate 3` respectively at the two ends of the Wavelike steel webplate 1` that is connected, by high-strength bolt 2` knuckle junction plate 3` is linked together then.Above-mentioned two kinds of types of attachment all directly connect by high-strength bolt, yet because bridge all has the gradient of vertical and horizontal in design and construction, and generally all be degree of uprising and thickness with the employed Wavelike steel webplate of the variation of stressed size, bolt hole is that factory reserves, and when therefore adopting high-strength bolt to connect, is difficult for aiming at bolt hole, cause difficulty is installed, thereby connect unbalance stress to making between the steel web, bring internal force, influence its intensity etc.; And adopt high-strength bolt to connect and cause cost up; And in order to guarantee the reliability of its connection, its number of bolt hole is more, thereby reduces Wavelike steel webplate junction intensity.(3), butt joint groove welding.Referring to Fig. 1 c, be processed into groove at the two ends that Wavelike steel webplate 1` is connected, directly weld and form soldering opening 4`.(4), overlapping fillet weld connects.Referring to Fig. 1 d, overlapping (overlap joint) directly welds at each port then and forms welded construction 5` together at the two ends that Wavelike steel webplate 1` is connected.Two kinds of above-mentioned types of attachment all adopt field Welding, though help reducing cost, when work high above the ground, place and ambient conditions are all relatively poor, weld not easy to operately, and easily produce dislocation, cause connect inaccurate, thereby produce internal force, influence its intensity etc.
The utility model content
The utility model mainly solves Wavelike steel webplate connection when having box girder construction now---and merely high-strength bolt connects or merely welding, existing the hole is difficult for or welding is not easy to operate etc. that thereby unfavorable factor causes internal stress for the steel web, influence technical problems such as its intensity, and then provide a kind of new Joining Structure of the internal stress that brings, i.e. Wavelike steel webplate combined connecting structure in the box girder bridge when being convenient to connect between the Wavelike steel webplate, effectively reduce cost, reduce construction.
The Wavelike steel webplate combined connecting structure is achieved through the following technical solutions in the box girder bridge of the present utility model: it includes two Wavelike steel webplates that are connected, link separately at two Wavelike steel webplates that are connected is provided with corresponding bolt hole, pass the link that bolt hole connects two Wavelike steel webplates by plain bolt, each link port is welded to connect the link of another Wavelike steel webplate.
Wavelike steel webplate in the Wavelike steel webplate box girder bridge is owing to adopt plain bolt and fillet weld combined connecting structure, when factory process, on Wavelike steel webplate, only reserve the bolt hole of minority, undertaken Wavelike steel webplate temporary fixed with plain bolt by bolt hole when Wavelike steel webplate is installed, for the welding of subsequently scene provides stable support and fixation, thereby made things convenient for the field Welding construction, guaranteed welding quality, helped reducing the internal stress that causes because of construction; Because the bolt hole count is few, help guaranteeing the intensity of its junction; And,, help reducing cost owing to adopt plain bolt.
Description of drawings
Fig. 1 is existing Wavelike steel webplate syndeton schematic diagram, and wherein Fig. 1 a is high-strength bolt single face friction connection diagram, and Fig. 1 b is knuckle single face friction connection diagram, and Fig. 1 c is butt joint groove welding schematic diagram, and Fig. 1 d is that overlapping fillet weld connects schematic diagram;
Fig. 2 is a combined connecting structure schematic diagram of the present utility model.
The specific embodiment
Referring to Fig. 2, combined connecting structure of the present utility model includes two Wavelike steel webplates 1 that are connected, the link separately of two Wavelike steel webplates 1 that are connected be provided with corresponding bolt hole several, its number of bolt hole is decided according to the height of Wavelike steel webplate, pass the link that bolt hole connects two Wavelike steel webplates with plain bolt 2, connect to play temporary fixed effect by bolt, for welding provides stable support, with the welding after guaranteeing, each link port is welded to connect the link of another Wavelike steel webplate, and the welding back forms fillet weld seam 3.
Claims (1)
1, Wavelike steel webplate combined connecting structure in the box girder bridge, include two Wavelike steel webplates (1) that are connected, it is characterized in that: the link separately at two Wavelike steel webplates (1) that are connected is provided with corresponding bolt hole, pass the link that bolt hole connects two Wavelike steel webplates by plain bolt (2), each link port is welded to connect the link of another Wavelike steel webplate.
