Description

Top board expansion bolt fastener
Technical field
The utility model relates to a kind of top board expansion bolt fastener, belongs to mechanical fastening device field.
Background technology
Usual fastening top board expansion bolt order: first install ascending stair → operator upper after certain altitude → cooperation personnel pass suspension rod → by this hanger erection in hole → screw up with a wrench; This method engineering time is long, loaded down with trivial details, complicated, efficiency is low, work consuming amount is large.
Summary of the invention
The purpose of this utility model is to provide that a kind of speed of application is fast, simple operation, saving is artificial, operating efficiency is high, installation cost is low top board expansion bolt fastener.
The purpose of this utility model is achieved in the following ways:
The utility model comprises steel pipe, large hexagonal socket wrench, it is characterized in that: the top be welded to connect at steel pipe of the large axis of hexagonal socket wrench and the axis being parallel of steel pipe, and the top of large hexagonal socket wrench exceeds the top 8 ~ 12mm of steel pipe; In the side of large hexagonal socket wrench in box spanner in hexagonal an angle centered by axially have a groove along box spanner, the width of groove is less than the width of box spanner endoporus, is provided with handle in the bottom of steel pipe.
The utility model has the advantages that: flexible to operation, speed of application is fast, it is artificial to save, operating efficiency is high, greatly can reduce installation cost, being applicable to architecture storey is 4m ~ 5.5m clear height, and top board expansion bolt suspension rod format diameter is the fastening category of 6 ~ 12mm.
Accompanying drawing explanation
Fig. 1 is the structural representation in the utility model use procedure;
Fig. 2 is top view of the present utility model.
Detailed description of the invention
With reference to accompanying drawing, the utility model comprises steel pipe 1, large hexagonal socket wrench 2, the top be welded to connect at steel pipe of the axis of large hexagonal socket wrench and the axis being parallel of steel pipe, and the top of large hexagonal socket wrench exceeds the top 8 ~ 12mm of steel pipe; In the side of large hexagonal socket wrench is in box spanner hexagonal an angle centered by axially have a groove 4 along box spanner, the width of groove is less than the width of box spanner endoporus, is provided with handle 3 in the bottom of steel pipe.
During use, the suspension rod combined is placed in the large hexagonal socket wrench at fastener top; Lift fastener suspension rod is tentatively placed in installing hole; Slightly tilt fastener, makes large hexagonal socket wrench top withstand on below nut, move up and down fastener, withstand in installing hole by complete for its expansion bolt; Inspection lay qualified after, the large hexagonal socket wrench of fastener is enclosed within expose on nut rotate make it fastening.
