Abstract
The utility relates to a combined bridge deck, belongs to the technical field of deck structures and solves the problems that the existing bridge deck is difficult to construct, easily fatigues, cracks and deforms and is high in maintenance cost. The combined bridge deck comprises a bottom steel plate, a steel frame, vent tubes, shear keys and a concrete layer; the steel frame, the vent tubes and the shear keys are all fixedly welded to the bottom steel plate; the steel frame, the vent tubes and the shear keys are covered with the concrete layer. The combined bridge deck is applied to bridge engineering construction.
Description
Technical field
The utility model belongs to bridge deck structure technical field, is specifically related to a kind of combined bridge deck.
Background technology
Bridge deck are main pressure-bearing parts of bridge, and the rational in infrastructure of bridge deck will bring a lot of convenience to construction and maintenance, and current bridge deck exist difficulty of construction large, easily produce fatigue, crack and distortion, the problems such as maintenance costs height.
Summary of the invention
The purpose of this utility model is to exist difficulty of construction large in order to solve current bridge deck, easily produces fatigue, crack and distortion, and the problem that maintenance costs is high, provides a kind of combined bridge deck, and its technical scheme is as follows:
A combined bridge deck, it comprises end steel plate, steel frame, permeability cell, shear connector and layer of concrete, and described steel frame, permeability cell, shear connector are all fixed with end Plate Welding, and are covered with layer of concrete on steel frame, permeability cell, shear connector;
Described steel frame connects and composes by organizing waveform band steel more, the lower end of waveform band steel and end Plate Welding, waveform band steel from the bottom to top width is gradually little, every group of waveform band steel upper end, is welded with reinforcing bar crossbeam, and two adjacent groups waveform band steel connects by arch steel;
The cross section of described permeability cell is semicircle, is provided with air-vent on permeability cell, between every two adjacent groups waveform band steel, is provided with a permeability cell;
Described shear connector is semicircular cylinder shape, between every two adjacent groups waveform band steel, two row's shear connectors is set, and two row's shear connector zigzag are arranged.
The beneficial effects of the utility model are: difficulty of construction is little, be difficult for to produce tired, crack and distortion, have high-durability, the secondary disaster such as can prevent that concrete from coming off, and maintenance costs is low.
accompanying drawing explanation:
Fig. 1 is overall structure schematic diagram of the present utility model;
Fig. 2 is the left side schematic diagram of Fig. 1;
Fig. 3 is two adjacent groups waveform band steel connection diagram in the utility model;
Fig. 4 is that the shear connector zigzag in the utility model is arranged schematic diagram.
the specific embodiment:
With reference to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, a kind of combined bridge deck, it comprises end steel plate 1, steel frame 2, permeability cell 3, shear connector 4 and layer of concrete 5, described steel frame 2, permeability cell 3, shear connector 4 are all welded and fixed with end steel plate 1, and are covered with layer of concrete 5 on steel frame 2, permeability cell 3, shear connector 4;
Described steel frame 2 connects and composes by organizing waveform band steel 2-1 more, the lower end of waveform band steel 2-1 and 1 welding of end steel plate, width is gradually little from the bottom to top for waveform band steel 2-1, every group of waveform band steel 2-1 upper end, be welded with reinforcing bar crossbeam 2-2, two adjacent groups waveform band steel 2-1 connects by arch steel 2-3;
The cross section of described permeability cell 3 is semicircle, is provided with air-vent 3-1 on permeability cell 3, between every two adjacent groups waveform band steel 2-1, is provided with a permeability cell 3;
Described shear connector 4 is semicircular cylinder shape, two row's shear connector 4, two row's shear connector 4 zigzag is set between every two adjacent groups waveform band steel 2-1 and arranges.
Preferably, described permeability cell 3 two ends grow end steel plate 1, and while preventing from constructing, concrete is blocked permeability cell 3.
The principle of utility model: waveform band steel 2-1 is width I convenient construction gradually from the bottom to top; The shear connector 4 that zigzag is arranged can increase bridge deck overall construction intensity, improves fatigue resistance, extends curing period; The setting of permeability cell 3 can reduce the differences such as the inside and outside temperature of bridge deck, humidity, effectively prevents crack and distortion.
