Abstract
A kind of portable steel slab bridge, relate to a kind of Simple bridge, comprise on main crane span structure, described main crane span structure and be provided with support crane span structure, described main crane span structure two ends are provided with flexible connecting device, described flexible connecting device comprises fixed strip, the contiguous block connecting described main crane span structure is provided with in described fixed strip, described contiguous block is provided with several junction buttons, described contiguous block two ends are provided with spring, described support crane span structure is provided with slideway, described slideway slides and is provided with bridge deck, described bridge deck two ends are provided with linkage.Compared with prior art, after several this steel slab bridges splicing one, the main crane span structure of any one steel slab bridge can ensure when being subject to mud extruding displacement bridge deck on this main crane span structure still with the bridge deck level connection joint on other steel slab bridges, ensure the stable of whole passage, prevent toppling of steel slab bridge.
Description
Technical field
The utility model relates to a kind of Simple bridge, particularly relates to a kind of mountable steel bridge.
Background technology
Mountable steel bridge is also known as Bailey bridge, this bridge makes the compositions such as light standardization truss element component and crossbeam, longeron, bridge deck, bridge chair and connector with high-strength steel, can be assembled into rapidly on the spot be applicable to the various truss bridge across footpath, load with special erection equipment.In China, early stage mountable steel bridge is mainly used in military affairs, i.e. military steel bridge, and present mountable steel bridge, except as except Combat Readiness Steel Bridge, has been widely used in the aspects such as rescue and relief work, traffic engineering, municipal hydraulic engineering, unsafe bridge reinforcing.Mountable steel bridge is also through being usually used in building engineering field, in building engineering field, mountable steel bridge is not be usually used in successive watercourse two sides, but be usually directly routed on the bad road surface of situation and form road surface bridge, pass through in order to facilitate heavy vehicle to avoid heavy vehicle to be trapped in muddy ground.
Summary of the invention
The utility model is for deficiency of the prior art, provide a kind of portable steel slab bridge, after several this steel slab bridges splicing one, the main crane span structure of any one steel slab bridge can ensure when being subject to mud extruding displacement bridge deck on this main crane span structure still with the bridge deck level connection joint on other steel slab bridges, ensure the stable of whole passage, prevent toppling of steel slab bridge.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals: a kind of portable steel slab bridge, comprise main crane span structure, described main crane span structure is provided with support crane span structure, described main crane span structure two ends are provided with flexible connecting device, described flexible connecting device comprises fixed strip, the contiguous block connecting described main crane span structure is provided with in described fixed strip, described contiguous block is provided with several junction buttons, described contiguous block two ends are provided with spring, described support crane span structure is provided with slideway, described slideway slides and is provided with bridge deck, described bridge deck two ends are provided with linkage.
In technique scheme, preferably, described bridge deck rotate and is dismountablely provided with the shielding cover matched with described linkage.
In technique scheme, preferably, described linkage comprises several casting lug thereons being arranged on described bridge deck end face, described casting lug thereon is provided with through hole, described linkage also comprises the fixed bar matched with described through hole, and described fixed bar two ends are provided with dismountable fixed cover.
This steel slab bridge is connected with other steel slab bridges by main crane span structure, compared with prior art this main crane span structure adopts flexible connection mode to connect, time an arbitrary main crane span structure is subject to mud extruding displacement, under the effect of flexible connecting device, only this main crane span structure can be allowed to move the main crane span structure that can not feed through to other, avoid whole passage to be impacted by mud and topple.Simultaneously under the effect supporting crane span structure sliding way, the displacement of main crane span structure also can not involve the bridge deck be arranged on this main crane span structure, makes the bridge deck on whole passage keep balance and stability, allows channels open.
Compared with prior art, after several this steel slab bridges splicing one, the main crane span structure of any one steel slab bridge can ensure when being subject to mud extruding displacement bridge deck on this main crane span structure still with the bridge deck level connection joint on other steel slab bridges, ensure the stable of whole passage, prevent toppling of steel slab bridge.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of portable steel slab bridge, comprise main crane span structure 1, described main crane span structure 1 is provided with and supports crane span structure 2, described main crane span structure 1 two ends are provided with flexible connecting device, described flexible connecting device comprises fixed strip 11, the contiguous block 12 connecting described main crane span structure 1 is provided with in described fixed strip 11, described contiguous block 12 is provided with several junction buttons 13, described contiguous block 12 two ends are provided with spring 13, described support crane span structure 2 is provided with slideway 21, described slideway 21 slides and is provided with bridge deck 3, described bridge deck 3 two ends are provided with linkage.Described linkage comprises several casting lug thereons 31 being arranged on described bridge deck 3 end face, described casting lug thereon 31 is provided with through hole, described linkage also comprises the fixed bar 4 matched with described through hole, and described fixed bar 4 two ends are provided with dismountable fixed cover 41.Described bridge deck 3 both sides are also provided with dismountable railing 33.Described bridge deck 3 rotate and is dismountablely provided with the shielding cover 32 matched with described linkage.
During use, several main crane span structures 1 only need mutually to be fastened can be linked together by the junction button 13 on adjacent contiguous block 12.And be arranged on support bridge deck 3 the adjacent casting lug thereons of needs 31 on crane span structure 2 interlaced after can be linked together by fixed bar 4.When mud starts motion to make a certain main crane span structure 1 that skew occur, under the effect of fixed strip 11 inner spring 13, that the main crane span structure 1 by mud impacts is only had to offset, other main crane span structures 1 can not be had influence on, simultaneously support the slideway 21 on crane span structure 2 act under bridge deck 3 there is relative displacement with main crane span structure 1, make bridge deck 3 still in position not with main crane span structure 1 interlock.Maintain the stable of whole passage like this, the situation that the bridge deck 3 avoiding mud to impact causing tilt to cause passage to use.
