Abstract
The utility model discloses a kind of truss-type steels, it includes profiled body made of being bent as plate, profiled body includes a bottom edge and two sides, bottom edge and side surround an accommodation groove jointly, it raises upward in the middle part of bottom edge and forms the first boss that a length direction along profiled body extends, the width of first boss is less than the width of accommodation groove.Through this structure, the mechanical performances such as anti-bending, anti-twist that can be improved the utility model still are able to mechanical property requirements needed for meeting building truss in the lesser situation of wall thickness, are conducive to the overall quality for controlling truss.
Description
Technical field
The utility model relates to architectural shapes, especially truss-type steel.
Background technique
In the building such as house, truss can be often constructed using fashioned iron, common fashioned iron has C-type steel, channel steel etc., in order to control
The weight of truss processed, the wall thickness of fashioned iron is by more strictly controlling, it is sometimes necessary to by the thickness control of fashioned iron 1.2mm with
It is interior.However the lesser fashioned iron of thickness, the performances such as anti-bending, anti-twist will decline, the intensity for being difficult to meet truss sometimes is wanted
It asks.Therefore, it is necessary to which the structure to truss-type steel improves, in the case where controlling wall thickness, meet needed for building truss
Mechanical property requirements.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of truss-type steel anti-bending, torsional resistance is good.
The technical scheme adopted by the utility model to solve the technical problem is as follows:
A kind of truss-type steel comprising profiled body made of being bent as plate, the profiled body include a bottom edge and
Two sides, bottom edge and side surround an accommodation groove jointly, raise upward in the middle part of the bottom edge and form one along profile master
The first boss that the length direction of body extends, the width of the first boss are less than the width of accommodation groove.
Preferably, the top surface of the first boss is connected with the side wall of first boss by cambered surface.
Preferably, the top surface of the first boss is greater than the thickness on bottom edge with the bottom surface of accommodation groove at a distance between the two.
Preferably, it raises upward at the top of the first boss and to form at least one parallel with side first convex
Item.
Preferably, the section of first raised line is arc-shaped.
Preferably, the top fold inward of the side and form the flanging parallel with bottom edge.
Preferably, the side wall of the side wall with accommodation groove of the first boss is greater than or equal to flanging at a distance between the two
Width.
The beneficial effects of the utility model are: the utility model includes profiled body made of being bent as plate, profile master
Body includes a bottom edge and two sides, and bottom edge and side surround an accommodation groove jointly, raise upward in the middle part of bottom edge and form one
Along the first boss that the length direction of profiled body extends, the width of first boss is less than the width of accommodation groove.It is tied by this
Structure can be improved the mechanical performances such as anti-bending, anti-twist of the utility model, still be able to meet in the lesser situation of wall thickness
Mechanical property requirements needed for constructing truss are conducive to the overall quality for controlling truss.
Detailed description of the invention
The present invention will be further described with reference to the accompanying drawings and examples:
Fig. 1 is the schematic cross-section of the utility model.
Specific embodiment
Referring to Fig.1, the utility model is a kind of truss-type steel comprising profiled body made of being bent as plate, the type
Material main body includes a bottom edge 1 and two sides 2, and bottom edge 1 and side 2 surround an accommodation groove 3 jointly, and the middle part on bottom edge 1 raises upward
And the first boss 4 that a length direction along profiled body extends is formed, the width of first boss 4 is less than accommodation groove 3
Width.
The top surface of first boss 4 is connected with the side wall of first boss 4 by cambered surface, be can avoid stress and is concentrated.
The top surface of first boss 4 is greater than the thickness on bottom edge 1 with the bottom surface of accommodation groove 3 at a distance between the two, can mention in this way
High amount of deflection, and then improve bending resistance.
The top of first boss 4 raises upward and forms at least one first raised line 5 parallel with side 2.Likewise,
The first raised line 5, which is arranged, also can be improved the intensity of the utility model, and counter-bending, anti-twisting performance can be improved.In addition, when two
When fashioned iron head and the tail overlap, the first raised line 5 may also function as the effect of positioning.
Further, the section of the first raised line 5 is arc-shaped, can avoid stress and concentrates.
The top fold inward of side 2 and form the flanging 6 parallel with bottom edge 1, to can further improve practical
Novel anti-bending, anti-twist performance.
Further, the side wall of the side wall with accommodation groove 3 of first boss 4 is greater than or equal to flanging 6 at a distance between the two
Width.When two fashioned iron are oppositely buckled with together, flanging 6 can sky between 3 inner sidewall of first boss 4 and accommodation groove
In gap, two relatively transverse movements of fashioned iron are avoided, and good positioning action can be played.
As described above, the intensity of the utility model is improved, anti-bending compared to the C-type steel and channel steel of identical wall thickness
The performances such as bent, anti-twist are also improved, machinery needed for can satisfy building truss in the lesser situation of wall thickness
Performance requirement, and be conducive to control the overall quality of truss.
Above-described embodiment is the preferred embodiment of the utility model, and the utility model can also have other embodiments.Ability
The technical staff in domain can also make equivalent deformation or replacement without departing from the spirit of the present invention, these equivalent changes
Type or replacement are all contained in range set by the claim of this application.
