Description
Technical field
The utility model belongs to traffic engineering technical field, the pre- manufacturing of beam slab being related to during bridge construction,
Ensure the foldable cat ladder of construction personnel or more beam slab safety.
Background technique
Currently, reinforced concrete girder slab is mainly carried out by the way of cast-in-place or prefabricated during bridge construction
Construction.The cast-in-place design position locating in construction drawing for the beam slab is poured, prefabricated then near the Bridge position
Or farther away place is poured, then secondary installing.Precast beam meets wanting for installation because that can be made in advance at any time
It asks, and does not influence construction speed, largely used in bridge construction.
When Liang Chang progress precast beam pours, construction personnel needs often precast beam progress operation and inspection up and down.
Although facilitating construction personnel or more, it is mating that the country lacks the mature construction of a set of safety it is required that scene is equipped with Simple crawling ladder
Equipment, in practical projects live Simple crawling ladder there are safeties it is poor, inconvenient to use the problems such as, influence construction personnel's peace
Complete and operating efficiency, and ladder storage transport is inconvenient, is unfavorable for reusing.
Utility model content
The purpose of this utility model is that: it is directed to during current science of bridge building precast beam panel construction, upper and lower beam slab ladder
The problems such as inconvenient, construction personnel can not ensure safely is moved, a kind of upper and lower ladder of collapsible precast beam is provided.
To achieve the above object, the utility model uses following technical scheme.
A kind of collapsible precast beam ladder, including pedestal 1, bracket 2, platform 3, stair 4, attached building ladder 5 up and down, feature
It is:
Bracket 2 includes two heel post disposed in parallel and crossbeam, and 2 column lower end of bracket and 1 one end of pedestal are hinged, bracket 2
The upper end of the column and 3 one end of platform are hinged；Crossbeam is arranged between two heel posts
Stair 4 are inclined between 3 other end of platform and the other end of pedestal 1, and stair 4 and 3 other end of platform pass through
Reserved jack and bolt 9 connect, and stair 4 and 1 other end of pedestal pass through hingedly；
Attached building ladder 5 is hinged with 3 side of platform.
The utility model further comprises following preferred embodiment:
2 column of bracket and 1 one end of pedestal, 2 column of bracket and 3 one end hinged place of platform are provided with bolt, bracket 2 and station
Using the fixed position of bolt when platform 3 turns to right angle.
Brace 8 for fixing is arranged in 3 other end of platform and 2 column of bracket, and wherein 8 one end of brace and platform 3 are hinged, separately
One end is connect by bolt with 2 column of bracket.
Station guardrail 6 is arranged in platform 3, and stair railing 7 is arranged in stair 4, and stair railing 7 is hinged by bearing 11 and stair 4,
Using the fixed position of bolt when station guardrail 6 and stair railing 7 turn to right angle.
Cross bar 10 is set on station guardrail 6, and both ends are provided with inserted link, reserve slot by station guardrail 6 and are installed.
The castor 12 of 1 four jiaos of pedestal installation braking devices.
The utility model principle is simple and convenient to operate, and is hingedly folded with the assembling of bolt realization ladder structure by many places,
The fixation and movement that position can be realized by pedestal castor, by ladder folding convenient, it moves, transports and stores；Attached building ladder can be square
Just precast beam above and below construction personnel, while platform can be used as the one-shot job platform of construction personnel, guardrail can ensure construction
Personnel's operation safety；The utility model can reuse in different engineerings convenient for storage and transport, reduce waste, ensure
Construction safety, improves construction efficiency.
Detailed description of the invention
