Abstract
The utility model relates to a metal section, particularly an open web metal section with complex cross-section. The utility model has the technical proposal that the utility model is provided with a mold cavity which is composed of a frame; slots are arranged respectively outside the frame and inside a bottom frame; an upwards opened upper slot is arranged outside an upper frame of the mold cavity, and the outer side of the bottom frame of the mold cavity is provided with a downwards opened lower slot; the shape of the middle part of the bottom frame of the mold cavity can be an arc shape which is bulged towards the interior of the mold cavity, and the upper surface of the arc shape is provided with an inner slot which is opened upwards. The utility model has the advantages that multiple of the slots are arranged on different positions, and different mold cavities with different shapes can be formed; when the utility model is used, structural members with different functions can be inserted or embedded in the slots in more options; simultaneously, connecting pieces can be internal-mounted and the integral beautiful appearance of the frame structure is ensured.
Description
Technical field
The utility model belongs to a kind of metal section, particularly a kind of hollow metal section bar with complex section.
Background technique
Metal section is used in the frame structure in mechanical industry more, in the known technology before the utility model is realized, the cross section of general metal section is very simple, content just to by after perforation on the section bar, directly the structural member of difference in functionality is fixed on the section bar surface with bolt, perhaps directly structural member is bonded in the surface of section bar.Above-mentioned design is limited to the function of use of section bar, and after fixing with structural member, connection part is exposed, and not only makes link fragile, and has destroyed the fluency of the integrity and the outward appearance of outward appearance.
Technological scheme
The purpose of this utility model provides a kind of hollow section with complex section, thereby has solved the problem that exists in the above-mentioned background technology.
Technical solution of the present utility model is: described hollow section with complex section, contain a die cavity that constitutes by frame, and be respectively arranged with slot in the inboard of the described frame outside, boundary frame area.
The arranged outside of the upper frame of described die cavity has the last slot of a upward opening, and the arranged outside of the boundary frame area of described die cavity has a following slot under shed.
The shape of the boundary frame area intermediate portion of described die cavity can be set to the circular arc to the die cavity internal projection, and the upper surface of this circular arc is provided with the interior slot of upward opening.
On the section bar described in the utility model, can have a plurality of slots at different positions and form difform die cavity, can insert or embed the structural member of difference in functionality at the position of slot in use, thereby more selection can be arranged.And only need simple connection, make the link can be built-in simultaneously, guaranteed the overall appearance of frame structure with bolt or rivet.
Description of drawings
Accompanying drawing 1 is the structural representation of a kind of embodiment in the utility model;
Accompanying drawing 2 is the schematic cross-section of accompanying drawing 1.
In the accompanying drawing: upper frame 1, boundary frame area 2, die cavity 3, last slot 4, following slot 5, interior slot 6.
Mode of execution
The arranged outside of described die cavity 3 upper frames 1 has the last slot 4 of a upward opening, and the arranged outside of die cavity boundary frame area 2 has a following slot 5 under shed.The shape of the boundary frame area intermediate portion of die cavity is provided with the circular arc to the die cavity internal projection, and the upper surface of this circular arc boundary frame area is provided with the interior slot 6 of upward opening.
Claims (3)
1. the hollow section with complex section contains a die cavity that is made of frame, it is characterized in that being respectively arranged with slot in the inboard of the described frame outside, boundary frame area.
2. hollow section according to claim 1, the arranged outside that it is characterized in that described die cavity upper frame has the last slot of a upward opening, and the arranged outside of described die cavity boundary frame area has a following slot under shed.
3. hollow section according to claim 1 is characterized in that the shape of described die cavity boundary frame area intermediate portion can be the circular arc to the die cavity internal projection, and the upper surface of this circular arc is provided with the interior slot of upward opening.
