Description
The present invention relates to a kind of bridge, particularly a kind of movable detachable highway cross-over bridge.
Along with expanding economy, it is more and more important that urban road construction has seemed, and the renovation of a large amount of limited roads in old urban area is also imperative., on originally with regard to crowded old urban area road, construct and to bring serious obstruction to traffic, or, influence the traffic of entire city, make troubles to people's work and study because of vehicle shunting causes away from the traffic jam in construction point area.And existing road construction method and equipment can not overcome this problem, thereby have brought many troubles to unit in charge of construction and relevant department.
In order to overcome above-mentioned shortcoming, the invention provides a kind of movable detachable highway cross-over bridge that can cooperate road construction and not influence normal traffic.
To achieve these goals, movable detachable highway cross-over bridge provided by the invention comprises:
One arc bridge floor, its two ends and ground are pressed close to mutually; And
An one secondary or secondary above arc main span that is used for supporting above-mentioned arc bridge floor, the top of this main span removably is connected with the arc bridge floor, and the lower end contacts with ground by a fastening devices and is fixing.
Movable detachable highway cross-over bridge provided by the invention, pavement construction can carry out below the arc bridge floor.And the vehicles or pedestrians that can travel on the arc bridge floor, thereby do not influence normal traffic; Under the situation that does not have construction, use this bridge can form temporary transient grade separation, alleviate the traffic jam of traffic intersection greatly, and the main span of this overpass bridge can be separated with the arc bridge floor, thereby can be shipped to the use point easily, and under the situation that road surface preparation is finished, can be by design, make this bridge in the time at night, assemble or to dismantle and finish, very little to traffic impact.

Fig. 2 is the schematic diagram of the described main span of Fig. 1;
Fig. 3 is the schematic diagram of the described arc bridge floor of Fig. 1;
Fig. 4 is the connection layout of the left and right bridge floor of one embodiment of the present of invention;
Fig. 5 is the schematic diagram of fastening devices of the main span of another embodiment of the present invention.
Below in conjunction with drawings and Examples, the present invention is described in detail:
Fig. 1 is provided by the invention moving or the structural representation of an embodiment of detachable highway cross-over bridge.As shown in Figure 1, this highway cross-over bridge comprises three main span 2-1,2-2, the 2-3 of arc bridge floor 1 and structural similarity; Arc bridge floor 1 comprises left bridge floor 1-1 and right bridge floor 1-2, they at the C place by the hasp (see figure 4) that links to each other with bolt.Certainly, can be according to size and the transportation and the requirement of bridge floor, this bridge floor also can be made an integral body or be divided into part more than three, makes in transportation, installs.Main span 2-1,2-2,2-3 are frame constructions, and it has two support beams supporting arc bridge floor 1, respectively are provided with a fastening devices G in the lower end of two supporting frames of main span 2-1,2-2,2-3.
Fig. 2 is the structural representation of the described main span 2-1 of Fig. 1,2-2,2-3.This main span 2-1,2-2,2-3 are arc frame constructions, and it comprises two supporting frames 26, connect the bow beam 29 and 30 and the fastening devices 9 that is arranged on the lower end of above-mentioned supporting frame 26 of above-mentioned supporting frame.Above-mentioned supporting frame 26 comprises that montant 126,127 has reached the crossbar 128,129 of booster action, and support crossbeam (bar) 125, support crossbeam 125 to fix along montant 126 upper and lower diverse locations according to the height of the support point of the arc bridge floor that will support, arc bridge floor 1 is being supported by above-mentioned crossbeam 125.Bow beam 29,30 is connecting two supporting frames 26, and it plays booster action, also can make other form certainly and for example with two cross couplings two montants 126 and 127 be coupled together.Fastening devices 9 comprises many for example three tires 22 and several three spikes 23 for example.Tire 22 is free to rotate after qi of chong channel ascending adversely is arrived to a certain degree, thereby main span is removable, is convenient to shipment.After tire 22 venting, the bottom surface of spike 23 can contact with ground, thereby plays the effect of supporting arc bridge floor 1.In order to achieve this end, the diameter d after tire 22 qi of chong channel ascending adversely is larger than the height h that equals spike 23 usually, that is to say, the position of the minimum point after the tire qi of chong channel ascending adversely will be a little more than the lowest point of spike 23, at this moment, if bleed a tire, then spike 23 can support landing ground.The rotating direction of tire 22 is consistent with the in-plane of supporting frame 26.
Fig. 3 is the outline drawing of the described arc bridge floor of Fig. 1.This bridge floor can be made a frame construction usually in advance, in this embodiment, above the frame construction of bridge floor make earlier about each several piece, middlely connect by screw, bolt or rivet mode, on framework, lay the good T-shape plate 231 of intensity then.
Fig. 4 is the connection diagram between the described bridge floor each several part of Fig. 1.In fact, if whole overpass bridge is very big, bridge floor 1 will be made several usually, is shipped to then to use point to use bolt 233 as shown in the figure to couple together again.In trapezoidal cross section of the junction stage of per two bridge floors, so that connect better.
Fig. 5 is the structural representation of fastening devices of the main span of another embodiment of the present invention.In this embodiment, when using pulley 122 and mobile main span, the arm 124 of rotary pulley 122, make pulley 122 support the supporting frame 126 of main span, at this moment, spike 123 " unsettled " is after being installed to the place, arm 124 is turned to shown position, so that the bottom surface of spike having peace of mind 123 contacts with ground.
Referring to figs. 1 through Fig. 4, when using highway cross-over bridge of the present invention, can be with main span 2,3 and 4 and the left bridge floor 2-1 of arc bridge floor 1, right bridge floor 2-2 transport to and use the place, with left bridge floor 2-1 and right bridge floor 2-2 frame to the support crossbeam 125 of main span 2,3 and 4, adopt the aspect of Fig. 4 to connect then, with tire 22 venting of main span 2,3 and 4, make support 23 support landing ground again.So, but traveling vehicle or pedestrian on the arc bridge floor 1, thus temporary grade separation can be formed.
Certainly, embodiment of the present invention can do various variations, for example:
If 1 arc bridge floor 1 is very big, main span more than three also can be set,, a main span can be set also if arc bridge floor 1 is very little, the structure of its main span can be done multiple variation according to the experience and the regulation of bridge design, and the intensity of bridge floor also should satisfy the requirement and the actual needs of bridge design;
2, the rotating direction of the tire 22 of main span is consistent with the in-plane of supporting frame 26 in the above-described embodiments, certainly also can be inconsistent for example at an angle of 90;
Support crossbeam 125 to support bridge floors if 3 supporting frames 26 do not adopt, but as the E among the figure, F point and supporting frame 26 2 of 2 of the front and back of arc bridge floor are removably coupled together, can reach purpose of the present invention equally by the hasp mode; And
4, arc bridge floor 1 also can be made the road surface form that can add turning according to implementing needs.
