Abstract
The utility model relates to a temporary guardrail used for stairs, which comprises a plurality of standard joints in sequential head-to-tail connection, wherein each standard joint comprises vertical bars and armrest transversal member bars. The temporary guardrail used for the stairs is characterized in that each standard joint comprises a starting vertical bar arranged above the stairs, a platform vertical bar arranged on a stair platform, and the armrest transversal member bars arranged between the vertical bars; a one-way armrest elbow is adopted for connecting the starting vertical bar and either armrest transversal member bar, and a two-way armrest elbow is adopted for connecting the platform vertical bar and either armrest transversal member bar. The starting vertical bar, the platform vertical bar and the armrest elbows forming each standard joint have uniform specifications, the lengths of the armrest transversal member bars can be determined according to stair stepping lengths in various projects, and the vertical bars are connected with stair stepping embedded parts through a pre-embedding mode. The utility model has the advantages of simple processing without electric welding, convenient connection, high efficiency, recycling and effective reduction of the project construction cost.
Description
Technical field
The utility model relates to the correlative technology field of building operations, specifically a kind of interim guard rail that is used for stair.
Background technology
The interim guard rail of stair of construction site adopts the scaffold tubes of Φ 48mm to set up mostly at present, yet its stability is a problem for a long time always, construction is got up comparatively complicated: the connection between the scaffold tubes does not have needs all between unified standard, the rod member that electric welding (being difficult to control welding quality), rod member are diversified in specifications to cause, can't process surely etc., therefore exist that operating process is numerous and diverse, poor stability, specification are mixed and disorderly, take and tear rod member dangerous, connecting portion open and shortcoming such as can't recycle, and are difficult to adapt to the needs of job site standardization effort.
The utility model content
The purpose of this utility model has provided the interim guard rail that is used for stair that a kind of standard is provided, to overcome existing stair construction protection railing poor stability, complicated operation, the low defectives such as using inconvenience that reaches of standardization level.
For achieving the above object, the utility model has adopted following technical scheme:
The utility model discloses a kind of interim guard rail that is used for stair, the standard knot of being made up of vertical rod and handrail transverse bar member that comprises that a plurality of head and the tail successively connect is characterized in that: each standard knot comprises the starting vertical rod that is arranged on the stair, be arranged at the platform vertical rod on the landing and be arranged at handrail transverse bar member between each vertical rod; Adopt unidirectional knee to be connected between described starting vertical rod and the handrail transverse bar member, the two-way knee of employing is connected between platform vertical rod and the handrail transverse bar member.
The uniform specification of the starting vertical rod of every group of standard knot of described formation, platform vertical rod, knee, handrail transverse bar member length can be decided according to the stair step length of each engineering.
Described each vertical rod links to each other with the stair step embedded part by pre-buried mode.
Described knee is fastenedly connected by bolt and standard knot.
Knee is processed surely by scaffold tubes, can directly be socketed on horizontal stroke, the pole steel tube, adopts bolt.
The beneficial effects of the utility model are:
1, owing to adopted bolt fixed mode, the potential safety hazard of avoiding welding (few weldering or do not weld) has improved the degree of safety of guard rail;
2, owing to used the standard knot of unified specification, can improve standardization level, and obtain neat effect attractive in appearance;
3, because connecting portion has been abandoned traditional welding manner, make the guard rail connecting portion neatly unified, beautified the sense organ effect;
4, because cross bar, vertical rod and knee are standard component, processing uniform specification and recyclable utilization effectively reduce the project construction cost, active response " economy type building site " requirement.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of starting vertical rod;
Fig. 3 is the structural representation of platform vertical rod.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
A kind of as shown in drawings interim guard rail that is used for stair, each standard knot comprise the starting vertical rod 1 that is arranged on the stair, be arranged at the platform vertical rod 2 on the landing and be arranged at handrail transverse bar member 3 between each vertical rod; Adopt unidirectional knee 4 to be connected between described starting vertical rod 1 and the handrail transverse bar member 3, the two-way knee 5 of employing is connected between platform vertical rod 2 and the handrail transverse bar member 3.
The uniform specification of the starting vertical rod of every group of standard knot of described formation, platform vertical rod, knee, handrail transverse bar member length can be decided according to the stair step length of each engineering.
Knee is fastenedly connected by M12 bolt and standard knot.Knee is processed surely by the scaffold tubes of Φ 60, can directly be socketed in horizontal stroke, vertical rod Φ 48 steel pipes, adopts the M12 bolt.
The erection procedure of guard rail is at first being provided with vertical rod basis built-in fitting, treat that intensity reaches after, vertical rod is installed on the built-in fitting, with knee its and stair transverse bar member are fastenedly connected (M12 bolt) then, like this, railing integral body promptly installs.The concrete parameter of the interim guard rail of stair of a certain job site employing below is provided:
1.208 meters of construction protection railing starting vertical rod height, divide two joints, unidirectional Φ 48mm coupling (124 millimeters of length) is arranged respectively at vertical rod top, middle part, be the usefulness of socket knee, 1.208 meters of railing platform vertical rod height, divide two joints, two-way Φ 48mm coupling (200 millimeters of length) is arranged respectively at vertical rod top, middle part, be the usefulness of socket knee.The knee specification is Φ 60mm steel pipe (160 millimeters of length of sides, 100 millimeters of another length of side), is fastenedly connected by two M12 bolts and standard member, and the bolt hole distance is 30,40 millimeters.Knee is processed surely by the scaffold tubes of Φ 60mm, can be directly and horizontal, the socket of vertical rod Φ 48mm steel pipe, adopt the M12 bolt.Built-in fitting, rod member, the elbow of forming interim guard rail on this all can be processed the recovery utilization rate height surely.
