Abstract
The utility model discloses a kind of channel design suitable for the maintenance of box beam internal overhaul, including the vertical ladder being arranged on the outside of box beam guardrail and dangle in the cat ladder of box beam gateway bottom, it is connected between the vertical ladder and cat ladder by being suspended at the walking passageway below box beam, the vertical ladder bottom is provided with steering platform, and annular enclosing is provided with the outside of the vertical ladder and cat ladder.The utility model is simple in construction, easy to manufacture, is easy to climb, and safety coefficient is higher, power when maintainer is saved trouble when passing in and out inside box beam, and is not limited by bridge pier height, Bridge position.
Description
Technical field
Bridge maintenance technical field is the utility model is related to, more particularly, to a kind of suitable for the logical of box beam internal overhaul maintenance
Road structure.
Background technology
Highway in China construction comes into the epoch of " paying equal attention to construction and maintenance ", and it is practicable " the full longevity to strengthen bridge maintenance management work
Life design " theory, ensure the important measure that bridge is reliably on active service in design life.For the bridge of box-structure, inspection
Mastery nurse makees mainly to carry out inside box beam, and the gateway entered inside box beam is arranged on box beam bottom mostly.At present
Approach into box beam bottom gateway mainly has two kinds：First, detect car by movable type bridge delivers to box beam by staff
Bottom gateway, this method is simple, but detection car cost of use is higher, and can take bridge floor track, influence bridge
The traffic capacity；Second, set vertical cat ladder on the bridge pier close to box beam bottom gateway, staff reach bridge pier root it
Afterwards, box beam bottom gateway is reached by climbing cat ladder, this method is not suitable for the bridge that inconvenience reaches at bridge pier place, and right
In high pier bridge, there is certain potential safety hazard in staff during vertical ladder is climbed.
The content of the invention
In order to solve the above problems, the utility model provides a kind of channel design suitable for the maintenance of box beam internal overhaul.
To achieve the above object, the utility model can take following technical proposals：
Channel design described in the utility model suitable for the maintenance of box beam internal overhaul, including be arranged on the outside of box beam guardrail
Vertical ladder and pendency box beam gateway bottom cat ladder, the walking between the vertical ladder and cat ladder by being suspended at below box beam
Passage is connected, and the vertical ladder bottom is provided with steering platform, and annular enclosing is provided with the outside of the vertical ladder and cat ladder.
The walking passageway includes the spandrel girder being connected by suspension rod with box beam, and the spandrel girder upper berth is welded with steel plate and is made
Road surface, the road surface both sides are provided with handrail guardrail.
When box beam is highly relatively low, the spandrel girder is horizontal beam, and the road surface is horizontally disposed with.
When box beam height is higher, the spandrel girder includes the inclined beams being connected with the vertical ladder and is connected with the cat ladder
Horizontal beam, the road surface above the inclined beams is step-like step ladder, and the road surface above the horizontal beam is horizontally disposed with.
Anti-slip veins are provided with the steering platform and road surface.
Channel design provided by the utility model suitable for the maintenance of box beam internal overhaul, it is simple in construction, easy to manufacture, it is easy to
Climbing, safety coefficient is higher, power when maintainer is saved trouble when passing in and out inside box beam, and is not limited by bridge pier height, Bridge position
System.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, the channel design described in the utility model suitable for the maintenance of box beam internal overhaul, including it is arranged on case
Vertical ladder 1 on the outside of beam guardrail and it is connected at box beam gateway and dangles in the cat ladder 2 of box beam gateway bottom, vertical ladder 1 and climbs
It is connected between ladder 2 by being suspended at the walking passageway below box beam.Due to box beam height it is higher, walking passageway be divided into tilting section and
Horizontal segment, include the suspension rod a for being connected to box beam bottom, suspension rod a bottoms set spandrel girder, then the welding steel system on spandrel girder
Into road surface, road surface both sides set security protection handrail guardrail 3.Specifically, above-mentioned spandrel girder includes and the phase of vertical ladder 1
Inclined beams 4.1 even and the horizontal beam 4.2 being connected with cat ladder 2, the road surface in inclined beams 4.1 is made of shaped steel and steel plate
Step-like step ladder 5.1, the road surface on horizontal beam 4.2 are the horizontal steel plate 5.2 being weldingly connected.When box beam is highly relatively low,
Walking passageway can be not provided with tilting section, only set horizontal segment between vertical ladder 1 and cat ladder 2.Stood in order to facilitate staff,
The steering platform 6 being connected with walking road is provided with the bottom of vertical ladder 1.In order to improve safety coefficient, in vertical ladder 1 and the outside of cat ladder 2
Annular enclosing 7 is provided with, and turns to platform 6 and road surface（Including step-like step ladder 5.1）Use with anti-slip veins
Checkered steel plate.
Above-mentioned vertical ladder 1, cat ladder 2, walking passageway use steel construction, and are connected by connector b with box beam or guardrail.
For concrete box girder, connector b anchors pontic using setting built-in fitting or bar planting mode；For steel box-girder, connector b is then adopted
Welded with welding manner and pontic.
In use, maintenance maintenance work personnel cross box beam guardrail, pass sequentially through vertical ladder 1, walking passageway and cat ladder 2 and reach
Box beam bottom gateway, after opening access panel c, smoothly it can enter inside box beam.
