Abstract
The utility model discloses a guide positioning connecting structure for a feet-lock bolt of a steel frame of a tunnel. The guide positioning connecting structure is characterized by comprising a guide tube and the feet-lock bolt, wherein the guide tube is welded to the steel frame; a drill hole is drilled in the guide tube and plays a role in guiding; the feet-lock bolt is installed through the guide tube, and the tail of the feet-lock bolt bends to form an L shape; the feet-lock bolt and the steel frame are welded into a whole. According to the guide positioning connecting structure of the feet-lock bolt, the problems that angle deviation occurs in the process of installing the feet-lock bolt and the steel frame, and the connection between the feet-lock bolt and the steel frame is not tight are solved, the installing accuracy of the feet-lock bolt is enhanced, the overall stability of the steel frame is improved, construction quality is guaranteed, and potential safety hazards are eliminated.
Description
Technical field
The utility model belongs to the construction technology of steelframe lock foot anchoring stock in constructing tunnel preliminary bracing, relates generally to steelframe lock foot anchoring stock guide-localization syndeton.
Background technology
Steel arch frame in constructing tunnel preliminary bracing generally need to be fixed with lock foot anchoring stock, to guarantee the stability of steelframe, traditional construction method is directly at steelframe side jewel hole, then install anchor pole, again anchor pole and steelframe are welded, the shortcoming of this method is, the angle of boring is difficult to meet design requirement, and the anchor pole of having installed after having holed is difficult to guarantee and steelframe fits tightly.
Utility model content
The purpose of this utility model is to provide a kind of tunnel steelframe lock foot anchoring stock guide-localization syndeton at this; The angular deviation that solution occurs when installing steelframe lock foot anchoring stock and lock foot anchoring stock are connected untight problem with steelframe, improve the precision of installing of lock foot anchoring stock, have improved the resistance to overturning of steelframe, have guaranteed construction quality, have eliminated potential safety hazard.
The utility model is to realize like this, construct a kind of tunnel steelframe lock foot anchoring stock guide-localization syndeton, it is characterized in that: comprise guide pipe and lock foot anchoring stock, described guide pipe is welded on steelframe, described guide pipe is drilled with the boring of the effect of playing guiding, by guide pipe, install the lock foot anchoring stock that described afterbody bends to L-type, and lock foot anchoring stock and steelframe are welded into an integral body.Solve the angular deviation and the lock foot anchoring stock that when installing steelframe lock foot anchoring stock, occur and be connected untight problem with steelframe, improved the precision of installing of lock foot anchoring stock, improved the resistance to overturning of steelframe, guaranteed construction quality, eliminated potential safety hazard.
According to tunnel described in the utility model steelframe lock foot anchoring stock guide-localization syndeton, it is characterized in that: described guide pipe adopts the steel pipe of external diameter 45mm, wall thickness 4mm, and guide pipe length is consistent with the width of steelframe.
According to tunnel described in the utility model steelframe lock foot anchoring stock guide-localization syndeton, it is characterized in that: described lock foot anchoring stock is ф 22HRB335 reinforcing bar, and afterbody bends to L-type.
The utility model has the advantage of: the utility model proposes a kind of lock foot anchoring stock guide-localization syndeton, solve the angular deviation and the lock foot anchoring stock that when installing steelframe lock foot anchoring stock, occur and be connected untight problem with steelframe, improved the precision of installing of lock foot anchoring stock, improved the resistance to overturning of steelframe, guarantee construction quality, eliminated potential safety hazard.
