Description
Technical field
The utility model relates to Bridge High-pier technical field of construction, specifically a kind of in Bridge Pier Construction, checking process, for the administrative staff such as constructor, management provide safe, comfortable, lower channel easily.
Background technology
Along with the develop rapidly that China's economy obtains, based on build one of transport development also develop rapidly.Bridge construction be also in transport development an important component part, and present bridge design is more and more tended to, and span is large, pier shaft is high.Although present bridge design level can reach these requirements, the structure design that span is large, pier shaft is high brings huge difficulty and danger to bridge construction.Four work area cove Xiang River two-wire grand bridges are marked for Chongqing-Guichow Railway civil engineering 9, this project 9# pier only reaches 55m in the vertical higher position of pier shaft, use conventional scaffold as constructor, management and administrative staff's construction, check that upper and lower passage sets up difficulty, safety factor is low, Given this situation, according to the actual conditions at scene, the safety climbing ladder developing a kind of suitable high pier construction is very necessary.
Utility model content
The utility model is the problem of upper and lower pier in order to solve constructor and administrative staff's safety in high pier construction process comparatively difficulty, thus provides the safety climbing ladder of a kind of suitable constructor and the upper and lower high pier construction of administrative staff.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of railroad bridge high pier construction safety climbing ladder, comprise vertical rod, cross bar and diagonal member, this safety climbing ladder also includes Z-shaped stair; Vertical rod is fixedly connected with by latch with cross bar; By the V-arrangement pin storehouse in vertical rod, the crossbar joint on cross bar and the diagonal draw bar on diagonal member, vertical rod, cross bar and diagonal member are fixedly connected to form the webmaster frame of a cuboid; Z-shaped stair are arranged in webmaster frame.
Described Z-shaped stair are provided with handrail.
Described Z-shaped stair are made up of 450mm*5mm band steel.
Described handrail by
30*2.5 steel pipe band steel is made.
Described cross bar is divided into horizontal cross bar and longitudinal cross bar.
Described horizontal cross bar is
48*3*1200 steel pipe, longitudinal cross bar are
48*3*2400 steel pipe.
Described diagonal member is divided into horizontal diagonal member and longitudinal diagonal member.
Described horizontal diagonal member is
48*2.5*2332 steel pipe, longitudinal diagonal member are
48*2.5*3125 steel pipe.
Described vertical rod is provided with door.
Described vertical rod is
48*3.25*3000 steel pipe.
The beneficial effect of employing technique scheme is:
1, safe and reliable, the bearing capacity of the utility model safety climbing ladder is strong, elegant in appearance, dismounting is flexible, convenient, be particularly suitable for bridge construction and be arranged on the other escape way upper and lower for constructor of bridge pier column, and manufacturing cost is low, construction plant requires low, and construction efficiency is high, saves material and duration.2, the utility model safety climbing ladder good stability, easy to process, cost is low, practical function is obvious, substantially increase safety factor and dress in engineering construction, tear efficiency open.
3, can also to be generalized to some other construction plant little for the utility model safety climbing ladder, and the environment that the scope of operation is high, as construction work decoration of exterior wall, water tower construction etc.
