Abstract
The utility model relates to a flat truss girder which comprises straight web members 1 made of square hollow section steel 11, diagonal web members 2 made of cold bending curling channel steel 12, and an upper and a lower chords 3 and 4 respectively composed of two roots of left-right symmetrical cold bending curling channel steel 12, wherein the straight web members 1 are vertically supported between the upper and the lower chords 3 and 4 at intervals; one diagonal web member 2 is arranged between two adjacent straight web members 1, and is slanting supported between the upper and the lower chords 4 and 5; the square hollow section steel 11 and the cold bending curling channel steel 12 are arrayed alternately in sequence. The utility model has the advantages that the cost is low, and the utility model can provide larger concealed space for cable running.
Description
Technical field
The utility model relates to a kind of plane frame beam that is used for large spans such as house, factory building, especially a kind of straight web member, diagonal web member and upper and lower string of being formed by two symmetrical clod wash lipped channels respectively of comprising, straight web member keep at a certain distance away vertical support down, between the lower edge, a diagonal web member is arranged, the plane frame beam of diagonal web member diagonal brace between upper and lower string between every adjacent two straight web members.
Background technology
Existing plane frame beam, it comprises straight web member, diagonal web member and the upper and lower string of being made up of two symmetrical clod wash lipped channels respectively, between two clod wash lipped channels of upper and lower string, be welded with a fill plate, straight web member keeps at a certain distance away and is vertically welded in down, the lower edge fill plate between, between every adjacent two straight web members a diagonal web member is arranged, the diagonal web member diagonal brace is between upper and lower string.The plane frame beam of this structure, because fill plate is generally thinner, so its moment of inertia is little, so, must support with more straight web member and diagonal web member, so just there is the high defective of complex structure, material and manufacturing cost.
The utility model content
The technical problem that the utility model solves is to overcome above-mentioned defective, provides a kind of plane frame beam simple in structure, with low cost and easy for installation to society.
The hidden advantage that provides than large space to cabling also is provided this plane frame beam.
The technical solution of the utility model is: design a kind of plane frame beam, it comprises straight web member, diagonal web member and the upper and lower string of being made up of two symmetrical clod wash lipped channels respectively, straight web member keep at a certain distance away vertical support down, between the lower edge, between every adjacent two straight web members a diagonal web member is arranged, the diagonal web member diagonal brace is between upper and lower string, described straight web member all is that square hollow section or described straight web member partly are that square hollow section and part are the clod wash lipped channel, and square hollow section and clod wash lipped channel be alternately arrangement successively.
Above-mentioned diagonal web member is square hollow section.
Above-mentioned diagonal web member is the clod wash lipped channel.
Above-mentioned diagonal web member partly is that square hollow section and part are the clod wash lipped channel.
Above-mentioned diagonal web member partly is that square hollow section and part are the clod wash lipped channel, and is square
Hollow section and clod wash lipped channel are alternately arranged successively.
The utility model all is that square hollow section or described straight web member partly are the clod wash lipped channel for square hollow section and part owing to having adopted straight web member, square hollow section and clod wash lipped channel replace structure arranged successively, like this, its moment of inertia is relatively large, then the clod wash lipped channel of upper and lower string can be selected less model for use, and, then reduced material cost owing to replaced original fill plate with square hollow section or clod wash lipped channel; Between the two clod wash lipped channels of upper and lower string is dead slot, and the hidden greater room that provides of cabling can be provided.
Description of drawings
Fig. 1: be the perspective view of a kind of embodiment of the utility model.
The specific embodiment
See also Fig. 1, a kind of plane frame beam, it comprises the straight web member 1 made with square hollow section 11, the diagonal web member made from clod wash lipped channel 12 2 and the upper and lower string of being made up of two symmetrical clod wash lipped channels 12 respectively 3,4, straight web member 1 keep at a certain distance away vertical support down, between the lower edge 3,4, between every adjacent two straight web members 1 diagonal web member 2 is arranged, diagonal web member 2 diagonal braces are between upper and lower string 4,5, and square hollow section 11 is alternately arranged successively with clod wash lipped channel 12.
Certainly, above-mentioned straight web member 1 also can all be made with square hollow section 11.Above-mentioned diagonal web member 2 also is that square hollow section or part are clod wash lipped channel 12 for square hollow section 11 and part, and with square hollow section 11 and clod wash lipped channel 12 alternately arrangement mode arrangement successively.
