Abstract
The utility model relates to a stair temporary guard bar, which belongs to the stair engineering technical field. The stair temporary guard bar comprises a stair guard bar which is composed of a stair tube, a transverse tube and a vertical tube which are connected and matched. The stair temporary guard bar is characterized in that two ends of the transverse tube which is connected with the upper end of the vertical tube are welded and connected with small iron tubes, the transverse tube is sleeved and matched with the stair tube through the small iron tubes, and the lower end of the vertical tube is fixedly connected with a floor rest platform. The amount of steel tubes which are used in the stair temporary guard bar is few, the stair temporary guard bar does not need fasteners and upright stanchions, saves the cost, does not occupy the stair, does not have projecting bar bodies, can return easily, and can be used repeatedly after first investment.
Description
Technical field
The utility model belongs to the stair field of engineering technology, is specifically related to the interim guardrail of a kind of stair.
Background technology
When the engineering structures work progress, according to the requirement of among JGJ59-99 " construction safety check criteria " JGJ80-91 " building operations high-rise working technical specification of security " the stair mouth and the stair of construction in layer being faced the limit, interim guardrail must be installed, safety when guaranteeing the eminence construction, the fall injury of pre-anti-personnel.Generally, the interim guardrail that stair mouth and stair face the limit adopts steel pipe and all kinds of fastener to combine, and employed steel pipe, fastener amount are big, the cost height, and must begin to carry out vertical rod until top layer from bottom, take ladder and do, hinder to enter the operation of stair unwrapping wire; Steel pipe is outstanding outward when setting up, and hinders and returns row.
The utility model content
At the problems referred to above that exist in the existent technique, the utility model purpose is to provide the technical scheme of the interim guardrail of a kind of stair.
The interim guardrail of described stair, comprise that connecting cooperation by ladder pipe, transverse tube, standpipe constitutes stair railing, it is characterized in that standpipe upper end connects the transverse tube two ends that are provided with and is welded to connect little iron pipe, and connect with terraced pipe box by little iron pipe and to cooperate the fixedly connected floor half space in the lower end of standpipe.
The interim guardrail of described stair is characterized in that the centre of standpipe is welded to connect little iron pipe, and connects with terraced pipe box by little iron pipe and to cooperate.
The interim guardrail of described stair is characterized in that fixedlying connected with the floor half space by connecting the built-in fitting that is provided with in the lower end of standpipe.
The interim guardrail of described stair is characterized in that the internal diameter of little iron pipe width less than terraced pipe.
The employed steel pipe amount of the interim guardrail of above-mentioned stair is few, need not fastener, vertical rod, saves cost, does not account for the ladder lane, does not have outer highlight bar body, easily returns row, and can have enough to meet the need use after dropping into first.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is another structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, and provide the specific embodiment.
The interim guardrail of stair connects cooperation by ladder pipe 1,1b, transverse tube 2, standpipe 3 and constitutes, transverse tube 2 two ends that standpipe 3 upper ends are welded to connect are welded to connect little iron pipe 5, and cooperate by little iron pipe 5 and ladder pipe 1,1b socket, fixedly connected with floor half space 6 by connecting the built-in fitting 4 that is provided with in the lower end of standpipe 3, the centre of standpipe 3 is welded to connect little iron pipe 5a, and cooperates with ladder pipe 1a, 1c socket by little iron pipe 5a.During installation, standpipe, the transverse tube of the bottom are installed earlier, the built-in fitting of electric welding standpipe lower end, the gate-type member of standpipe and transverse tube welding formation is fixed on the floor half space, again with terraced Guan Yiduan be welded on this standpipe, transverse tube on and width cooperate less than the little iron pipe socket of terraced bore, the standpipe on the ladder pipe other end and the second floor half space and the gate-type member socket of transverse tube welding formation cooperate, and then fix standpipe on the second floor half space, and successively upwards install by the electric welding built-in fitting.
