Abstract
The utility model discloses a self-made circulation bend connecting tool for stair protection at different heights and the tool is used for a connection on corners of down and upstairs. The connecting tool comprises a steel pipe, two ends of which are provided with bends; each bend is provided with a nut and a bolt; two ends of each bend are respectively provided with an expanded head; each expanded-head is connected with the steel pipe and a horizon bar of the corner of the stair to be connected; each expanded head is provided with a screw; the screw hole is provided with a nut; the nut is provided with a bolt; a head part of the bolt is arranged outside the bend wall; and a screw part of the bolt is arranged inside the nut and the pipe wall of the expanded head. The self-made circulation bend connecting tool for stair protection at different heights makes a breakthrough for traditional methods of manufacturing stair protecting barriers and provides a new type of corner connecting tool for stair protecting barriers. A circular head is made on the corner to avoid body scratches, thereby protecting personal safety; standardization of stair protection is further realized with beautiful design; the tool can be recycled; standardized stair protection is achieved; operation is facilitated; cost is saved; and on-site overall appearance is improved.
Description
Technical field
The utility model relates to a kind of fastening means, and especially a kind of self-control can be had enough to meet the need the not contour elbow fastening means of stair protection.
Background technology
At present, when setting up the stair guard rail, be to run stair horizon bar on the corner up and down with steel pipe post to link together in the common way of stair corner and landing slab corner, the method will cause stair protective materials consumption to strengthen, integral body is disorderly and unsystematic, influence is attractive in appearance, and increases material cleaning difficulty when removing.
The utility model content
Existing stair corner and landing slab corner common way protective materials consumption are big, influence is attractive in appearance and removed material cleaning difficulty is big in order to solve, and the utility model provides little, safe, the attractive in appearance and reusable self-control of a kind of protective materials consumption can have enough to meet the need the not contour bend pipe fastening means of stair protection.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
A kind of self-control can be had enough to meet the need the not contour elbow fastening means of stair protection, comprises steel pipe, and described steel pipe two ends are provided with bend pipe, and described bend pipe is provided with nuts and bolt.
Described bend pipe two ends are provided with enlarged footing.
Described enlarged footing and steel pipe are connected with stair corner horizon bar to be connected.
Described enlarged footing is provided with screw, and described screw is provided with nut, and described nut is provided with bolt.
Described bolt head partly is located at outside the bend pipe wall, and described bolt screw portion is located in nut and the enlarged footing tube wall.
Described bend pipe bendable angle is 0 °-180 ° scope.
The beneficial effects of the utility model are:
The utility model has been broken through the way of traditional stair guard rail, and a kind of novel stair guard rail corner fastening means is provided.On the corner make fillet and avoid scraping wound body, guarantee personal safety, can realize the stair level of protectionization again, generous, attractive in appearance, and can reuse, realized the standardization protection of stair, made things convenient for construction, saved cost, improved on-the-spot overall image.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
