Abstract
The invention discloses a node structure for connecting a corrugated steel web and concrete. The node structure is characterized in that a corrugated edge of the corrugated steel web is connected with a flat steel plate in a welding manner, transverse perforated steel plates are welded at intervals on the corrugated steel web and the flat steel plate along the longitudinal direction, a reinforcing steel bar is arranged in each transverse perforated steel plate in a penetrating manner, and the steel web and the flat steel plate are coated with concrete, so that the corrugated steel web, the flat steel plate, the transverse perforated steel plates and concrete form an entirety. The node structure has advantages that the problem of an additional downward pulling force caused by downward insertion of plate into a concrete base plate in a traditional connection way can be avoided, and the problem of the traditional connection way that the structural durability is reduced due to the permeation of rainy water into the contact surface between the corrugated steel web and the concrete also can be avoided. The connection node is simple in structure, reasonable in stress and convenient in construction.
Description
Technical field
The invention belongs to technical field of bridge engineering, relate to the joint structure that Wavelike steel webplate is connected with concrete.
Background technology
The connection of Wavelike steel webplate and concrete base plate outside traditional waveform steel web grider bridge, general employing insert type and two kinds, edge of a wing type.Insert type refers to that Wavelike steel webplate inserts concrete base plate, is provided with weldering nail or is provided with circular hole and runs through reinforcing bar to play connection function in the Wavelike steel webplate both sides of inserting concrete base plate; Edge of a wing type refers to connect one block of plain plate in the waveform side weld of Wavelike steel webplate, connects concrete side be provided with weldering nail or be provided with open pore steel plate and run through reinforcing bar and play connection function at plain plate.
There is the additional lower pulling force problem that concrete base plate drop-down insertion plate causes in traditional connected mode, and can not solve the problem of the structure durability reduction caused after rainwater infiltrates Wavelike steel webplate and concrete contact surface.For this reason, research and design goes out the Types of nodes of a kind of reasonable stress, durable in use, easy construction, and tool is of great significance.
Summary of the invention
The object of the present invention is to provide the joint structure that a kind of Wavelike steel webplate is connected with concrete, improve structure durability, the problem that the structure durability caused after the additional lower pulling force problem avoiding concrete base plate drop-down insertion plate to cause and conventional coupling arrangement infiltrate Wavelike steel webplate and concrete contact surface by rainwater reduces, reduce node construction difficulty, and simple structure, reasonable stress.
For reaching above object, solution of the present invention is: the joint structure that a kind of Wavelike steel webplate is connected with concrete, it is characterized in that the waveform side weld of Wavelike steel webplate connects one block of plain plate, longitudinally lateral opening steel plate is welded at a certain distance again on Wavelike steel webplate and plain plate, Wavelike steel webplate and plain plate Outsourcing Concrete, make Wavelike steel webplate, plain plate, lateral opening steel plate and concrete form entirety.Wear reinforcing bar in described lateral opening steel plate, described waveform steel abdomen and plain plate are furnished with weldering nail in concrete side.
Owing to have employed such scheme, the present invention has following characteristics: welding weldering nail and open pore steel plate on Wavelike steel webplate and plain plate also run through reinforcing bar, enhance steel work and are connected with concrete; Wavelike steel webplate waveform limit arranges plain plate, as structure floor, and the location of Wavelike steel webplate in constructability; Wavelike steel webplate peace steel plate external wrapping concrete, avoid the additional lower pulling force problem that concrete base plate drop-down insertion plate causes, it also avoid the problem of the structure durability reduction caused after rain infiltrates Wavelike steel webplate and concrete contact surface simultaneously, improve the durability of structure.The invention has the advantages that this connected node simple structure, reasonable stress, easy construction.
Accompanying drawing explanation
Fig. 1 is the joint structure schematic diagram that Wavelike steel webplate of the present invention is connected with concrete.
Detailed description of the invention
See Fig. 1, the joint structure that a kind of Wavelike steel webplate is connected with concrete, it is characterized in that the waveform side weld of Wavelike steel webplate 1 connects one block of plain plate 2, on Wavelike steel webplate 1 and plain plate 2, longitudinally weld lateral opening steel plate 3 more at a certain distance form entirety, the side of lateral opening steel plate 3 is welded with Wavelike steel webplate 1, opposite side welds with plain plate 2, Wavelike steel webplate 1 and plain plate 2 Outsourcing Concrete 4, makes Wavelike steel webplate, plain plate, lateral opening steel plate and concrete form entirety.Wear reinforcing bar in described lateral opening steel plate 3, described waveform steel abdomen and plain plate outside bag concrete concrete side are furnished with weldering nail 5.Wavelike steel webplate 1 contacts concrete with the one side of plain plate 2, and another side exposes, and installing reinforcing bar in open pore steel plate and hole thereof is wrap in inside concrete completely.Plain plate 2 is levels or flushes with concrete bottom surface.The angle of Wavelike steel webplate 1 and plain plate 2 is generally between 90 ~ 120 degree, and corner dimension can require to arrange according to structural sections face.By increasing weldering plain plate bottom Wavelike steel webplate, make Wavelike steel webplate and plain plate external-wrapped bottom plate concrete, catch concrete base plate, the additional lower pulling force that the concrete base plate drop-down insertion plate avoiding conventional coupling arrangement existence causes, it also avoid the problem that the structure durability that causes after conventional coupling arrangement infiltrates Wavelike steel webplate and concrete contact surface by rainwater reduces simultaneously, and reasonable stress, durable in use, easy construction.Spacing between lateral opening steel plate is generally at 750mm ~ 850mm.The height of Wavelike steel webplate Outsourcing Concrete is the height of concrete base plate, and the length of plain plate Outsourcing Concrete, generally at 450mm ~ 550mm, can adjust as the case may be.
