Abstract
The utility model relates to a tubular pillar non-radial drilling tool, and belongs to the technical field of steel structure manufacturing. The tubular pillar non-radial drilling tool comprises a triangular tool (1) and a circular tubular pillar (2), the triangular tool (1) is welded to an arc face of the circular tubular pillar (2), the triangular tool is composed of two connecting boards, the two connecting boards are welded to each other to form a right angle, and positioning holes are formed in the connecting boards. The tubular pillar non-radial drilling tool has the advantages that due to the fact that the triangular tool is adopted, a plane is provided to enable drilling equipment to be attached to the plane to carry out drilling, and a drill is guided to penetrate through the arc face of the circular steel pipe column to form a puncture hole. On one hand, the size of the drilling hole is kept to be consistent with the size of the hole meeting design requirements, and column section bearing force is not excessively weakened; on the other hand, the drill hole is attractive in appearance.
Description
Technical field
The utility model relates to the non-radial bore frock of a kind of tubular pillar, belongs to the structure steel fabrication technical field.
Background technology
Concrete-filled circular steel tube column is widely used in high building structure.When concrete-filled circular steel tube column is connected with beams of concrete, and the vertical consecutive hours of beams of concrete, usually require the Reinforcement of beams of concrete to run through the round steel tubing string.Because of in this case to wear the muscle hole general along tubular pillar not radially, the angle on-right angle of centerline hole and pipe arcwall face tangent line, current rig can't be attached directly on the tubular pillar arcwall face and be holed, and usually adopts the method for hand cut to process.Hand cut hole out is larger than the hole size of designing requirement on the one hand, has weakened to a greater degree the column section bearing capacity; The hole cut out on the other hand is very not attractive in appearance.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of tubular pillar non-radial bore frock, and it can effectively solve the non-footpath boring of tubular pillar problem.
The purpose of this utility model is achieved in that the non-radial bore frock of a kind of tubular pillar, it comprises triangle frock and round steel tubing string, described triangle frock is welded on the arcwall face of round steel tubing string, described triangle frock consists of two connecting plates, described two connecting plates are welded to each other the formation right angle, on described connecting plate, offer locating hole.
During boring, in the round steel tubing string arcwall face position spot welding triangle frock of needs boring, and require hole orthographic projection on round steel pipe on the edged surface always of triangle frock.The drill bit of rig is vertical by the boring steel plate surface with the triangle frock, makes rig be attached directly to some upper boring of triangle frock, and guides drill bit through curved circular steel pipe face, realizes perforation.
Compared with prior art, the utlity model has following beneficial effect:
The non-radial bore frock of a kind of tubular pillar of the utility model, by adopting the triangle frock, provide plane to be attached on its face and to hole for rig, and the guiding drill bit is realized perforation through the arcwall face of round steel pipe.Such boring is consistent with the hole size of designing requirement on the one hand, is unlikely to weaken too much the column section bearing capacity; Hole on the other hand beautiful attractive in appearance.
The accompanying drawing explanation
The axonometric drawing that Fig. 1 is the non-radial bore frock of a kind of tubular pillar of the utility model.
The top view that Fig. 2 is Fig. 1.
Wherein:
Triangle frock 1
Round steel tubing string 2.
The specific embodiment
Referring to Fig. 1, Fig. 2, the non-radial bore frock of a kind of tubular pillar of the utility model, it comprises triangle frock 1 and round steel tubing string 2, described triangle frock 1 is welded on the arcwall face of round steel tubing string 2, described triangle frock consists of two connecting plates, described two connecting plates are welded to each other the formation right angle, on described connecting plate, offer locating hole.
During boring, in the round steel tubing string 2 arcwall face position spot welding one triangle frocks 1 of needs boring, make rig be attached directly to some upper boring of triangle frock 1, and guide the arcwall face of drill bit through round steel tubing string 2, realize perforation.
Claims (1)
