Description

Metro station excavation bracing members set up personnel's fall arrest facility

Technical field

The utility model is related to Tunnel Engineering, more particularly to a kind of Metro station excavation bracing members set up personnel's fall arrest and set It applies.

Background technology

In recent years with the fast development in city since, city incity urban rail transit construction is more like a raging fire, subway station Most of support forms for adding inner support for fender post, since station is typically all two layers or three-decker, foundation depth reaches 15m~25m, bracing members erection quantities is bigger, and personnel need walk in steel purlin on foot in erection process.There are operation people Member's high falling risk, security risk are larger.

Traditional bracing members erection method be personnel climbed to by cat ladder need set up bracing members one layer of steel purlin on, then Pad it need to extremely set up Support Position, whole process since travel distance is long, and periphery without safety belt can bolt hang position, worker All it is often very long a distance of walking in steel purlin without any safety measure, it is very dangerous.Therefore, A kind of method for being badly in need of in bracing members erection process preventing personnel from falling, to solve such technical problem.

Utility model content

The technical problem to be solved by the utility model is to provide a kind of Metro station excavation bracing members, erection personnel are anti-fall Facility is fallen, to fully ensure that the safety of the operating personnel in steel purlin, and advantageously reduces construction cost.

Technical solution is as follows used by the utility model solves its technical problem：

The Metro station excavation bracing members of the utility model set up personnel's fall arrest facility, including spaced fender post With the steel purlin being fixedly mounted on each fender post, it is characterized in that：The top of the steel purlin is fixedly installed on each fender post The overhanging end of expansion bolt, expansion bolt has hook part, and elongated round steel is hung in the hook portion of each expansion bolt.

The utility model has the beneficial effects that being formed by expansion bolt, elongated round steel and existing fender post fixed Combination Falling proof device can fully ensure that operating personnel's safety in steel purlin, and not influence it and freely walk；It is easy to operate, it applies Work is rapid, simple with material, and structure is common, and easy to assembly, strong applicability can effectively reduce construction cost.

Description of the drawings

This specification includes following two width attached drawing：

Fig. 1 is that the utility model Metro station excavation bracing members set up personnel's fall arrest service plan；

Fig. 2 is that the utility model Metro station excavation bracing members set up personnel's fall arrest facility elevation.

Component and corresponding label are shown in figure：Fender post 10, steel purlin 11, bracing members 12, expansion bolt 21, elongated circle Steel 22.

Specific implementation mode

The utility model is further illustrated with reference to the accompanying drawings and examples.

Referring to Figures 1 and 2, the Metro station excavation bracing members of the utility model set up the fall arrest facility of personnel, including Spaced fender post 10 and the steel purlin 11 being fixedly mounted on each fender post 10.The top of the steel purlin 11 is each Expansion bolt 21 is fixedly installed on fender post 10, the overhanging end of expansion bolt 21 has hook part, in the curved of each expansion bolt 21 Hook portion hangs elongated round steel 22.

With reference to Fig. 2, while setting up steel purlin 11, the position of certain distance is arranged and is respectively going along with sb. to guard him above steel purlin 11 Expansion bolt 21 is set in stake 10, then elongated round steel 22 is hung in the hook part of 21 exposed junction of expansion bolt.With elongated circle Steel 22 is used as the fixed tie point of construction personnel's safety belt.Under construction personnel to after in steel purlin, as long as safety belt is bolted to logical On long round steel 22,12 decorating position of bracing members can be run to safely in steel purlin 11, it is extremely convenient.In general, expansion bolt 21 bearing capacity is not less than 8KN, and the diameter of elongated round steel 22 is not less than 16mm.

The above is the utility model Metro station excavation bracing members erection personnel's fall arrest facility that explains through diagrams Some principles, be not intended to by the utility model be confined to shown in and the concrete structure and the scope of application in, therefore it is every It is possible that the corresponding modification being utilized and equivalent, belong to the apllied the scope of the claims of the utility model.
