Description
Technical Field
The utility model relates to a rack connects subassembly technical field, concretely relates to high strength conical head.
Background
The bolt ball node grid structure has the characteristics of light dead weight, high strength, good earthquake resistance, simple construction and installation, environmental protection, energy conservation and the like, and is widely applied to large-span buildings in recent years. The traditional bolt ball node net rack rod piece is manufactured by manual welding or semi-automatic welding, the labor productivity is low, and the product quality discreteness is large. If the conical head for the bolt ball joint net rack matched with the traditional process is applied to a full-automatic production line process, the assembly precision cannot meet the requirements of national technical standards due to various factors such as the wall thickness deviation of a steel pipe. The bolt ball node net rack rod piece is formed by welding conical heads or sealing plates at two ends of a round steel pipe and heightening bolts in the two ends, and the high-strength bolts are connected with bolt balls through sleeves in a construction site.
However, when the existing welding conical head is used, the existing welding conical head cannot be well positioned and welded with a steel pipe generally, the existing welding conical head cannot well limit the sleeve, the concentricity of the sleeve and the conical head cannot be well guaranteed, and a gasket of a high-strength bolt is easy to twist and deflect and easy to deform when the existing welding conical head is connected with the high-strength bolt, so that the service life of the existing welding conical head can be greatly shortened.
SUMMERY OF THE UTILITY MODEL
In order to comprehensively solve the problems, the high-strength conical head is provided aiming at the defects in the prior art.
In order to achieve the above purpose, the utility model adopts the following technical means:
the utility model provides a high strength conical head, includes the conical head body, conical head body rear portion is provided with and is used for with the steel pipe joint and leave the grafting portion of welding groove, the anterior inboard of conical head body is provided with the joint groove one that corresponds with the high strength bolt gasket, the anterior outside of conical head body is provided with the joint groove two that corresponds with the sleeve pipe.
Further, the inner diameter of the first clamping groove is the same as the outer diameter of the high-strength bolt gasket, and the depth of the first clamping groove is smaller than the thickness of the high-strength bolt gasket.
Further, the inserting part comprises a vertical part corresponding to the steel pipe and a bevel part connected with the vertical part.
Further, the included angle between the vertical part and the bevel part is 150 degrees.
Furthermore, arc transition is adopted between the front end face of the cone head body and the conical surface.
Compared with the prior art, the utility model, have following advantage:
the utility model discloses simple structure, through grafting portion can be fine with steel pipe cooperation location, and leave the bevel portion and more make things convenient for the welding, be provided with assurance conical head and telescopic concentricity that sleeve joint groove two can be fine, be provided with the fixed high strength bolt gasket that joint groove one can be better, avoid the gasket to twist partially, can improve the life of gasket greatly.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
As shown in fig. 1-2: the embodiment provides a high strength conical head, including conical head body 1, conical head body 1 rear portion is provided with and is used for 5 joints of steel pipe and leaves grafting portion 101 of welding groove, the anterior inboard of conical head body 1 is provided with the joint groove 102 that corresponds with high strength bolt gasket 2, the anterior outside of conical head body 1 is provided with the joint groove two 4 that corresponds with sleeve pipe 3.
The inner diameter of the first clamping groove 102 is the same as the outer diameter of the high-strength bolt gasket 2, the depth of the first clamping groove 102 is smaller than the thickness of the high-strength bolt gasket 2, better gasket fixing is facilitated, and the pressing effect of the gasket cannot be influenced.
The inserting part 101 comprises a vertical part 103 corresponding to the steel pipe 5 and a bevel part 104 connected with the vertical part 103, and welding is facilitated better.
The included angle between the vertical part 103 and the bevel part 104 is 150 degrees, so that the welding effect is better.
The front end surface of the cone head body 1 and the conical surface are in arc transition.
This embodiment simple structure, through grafting portion 101 can be fine with steel pipe cooperation location, and leave the more convenient welding of bevel portion 104, be provided with the assurance conical head that sleeve joint groove two can be fine and telescopic concentricity, be provided with the fixed high strength bolt gasket that joint groove one can be better, avoid the gasket to twist partially, can improve the life of gasket greatly.
The present invention is illustrated by way of example and not by way of limitation. It will be apparent to those skilled in the art that other variations and modifications of the present invention can be made in light of the above teachings, and it is not necessary or necessary to exhaustively enumerate all embodiments herein, and it is intended that all such obvious variations and modifications are within the scope of the present invention.
