Description
Technical Field
The utility model relates to a supporting member belongs to building structure engineering technical field.
Background
The central support has larger lateral rigidity and relatively simple structure, and plays a great role in improving the lateral rigidity resistance of the structure and improving the internal force distribution of the structure. Limited by the use condition of the building, the herringbone central support mode can be adopted sometimes; however, under repeated horizontal force, the herringbone bracing is easy to generate compression buckling, and the compression resistance is degraded, so that large unbalanced force of the truss at the bracing position can be caused, and the cross beam can be damaged and the floor can be sunk.
SUMMERY OF THE UTILITY MODEL
The utility model provides a not enough to prior art, the utility model provides a supporting member, the unbalanced force that reducible truss appears in support department.
In order to achieve the above purpose, the utility model provides a following technical scheme: a supporting member comprises a truss and interlayer diagonal braces, wherein the truss comprises upper chords, lower chords and web members, the web members are obliquely arranged between the upper chords and the lower chords, a plurality of web members are arranged, two adjacent web members are arranged in a herringbone shape, each web member comprises an auxiliary force transmission web member and two adjacent direct force transmission web members, a herringbone opening formed by the two adjacent direct force transmission web members is downward, the interlayer diagonal braces are arranged on downward extension lines of the two direct force transmission web members, and the length of each direct force transmission web member is smaller than that of each interlayer diagonal brace; the stress ratio of the direct force transfer web member is greater than the stress ratio of the auxiliary force transfer web member; the stress ratio of the direct force transmission web member is larger than that of the interlayer diagonal brace; the supporting members are designed according to the principle that the upper chord member and the lower chord member of the strong truss, the strong interlayer supporting and strong paving help to transmit force web members and the weak direct force to transmit force web members; the supporting member can realize that the direct force transmission web member is firstly bent or yielded under the action of repeated horizontal force, and the compressive buckling bearing capacity of the supporting member is reduced or not reduced because the direct force transmission web member is shorter than the interlayer diagonal bracing, and the unbalanced force borne by the truss is smaller.
The utility model is further arranged that the direct force transmission web member is enclosed by two different curved clothes point steels; when the direct force transmission web member is buckled or buckled, the relatively low-camber point steel can consume energy after entering plasticity, and the damping ratio of the supporting component can be increased.
The utility model is further arranged that the two ends of the web member are respectively welded on the upper chord member and the lower chord member; the interlayer inclined strut is welded on the lower chord; the welding mode is adopted to facilitate the manufacturing.
The utility model discloses set up as further, the contained angle of web member and upper chord member is 30-60 degrees.
Drawings
Fig. 1 is a schematic structural view of the support member of the present invention.
In the figure: 1. an upper chord; 2. a lower chord; 3. an auxiliary force transfer web member; 4. A direct force transfer web member; 5. and (4) interlayer diagonal bracing.
Detailed Description
An embodiment of a support member according to the present invention is further described with reference to fig. 1.
A supporting component comprises a truss and interlayer diagonal braces 5, wherein the truss comprises an upper chord 1, a lower chord 2 and web members, the web members are obliquely arranged between the upper chord 1 and the lower chord 2, the web members are provided with a plurality of web members, two adjacent web members are arranged in a herringbone shape, the direct force transmission web members 4 are arranged in the middle of the truss, each web member comprises an auxiliary force transmission web member 3 and two adjacent direct force transmission web members 4, openings of the herringbone shapes formed by the two adjacent direct force transmission web members 4 are downward, the interlayer diagonal braces 5 are arranged on downward extension lines of the two direct force transmission web members 4, and the length of the direct force transmission web members 4 is smaller than that of the interlayer diagonal braces 5; the stress ratio of the direct force transfer web member 4 is greater than the stress ratio of the auxiliary force transfer web member 3; the stress ratio of the direct force transmission web member 4 is larger than that of the interlayer diagonal brace 5; under the action of repeated horizontal force, the direct force transmission web member 4 is firstly bent or yielded, and the direct force transmission web member 4 is shorter than the interlayer inclined strut 5, so that the bearing capacity of the supporting member is reduced slightly after the direct force transmission web member 4 is bent, and the unbalanced force borne by the truss is smaller.
Furthermore, the direct force transmission web member 4 is formed by enclosing two kinds of steel with different curved service points; when the direct force transmission web member 4 is bent or yielded, the relatively low-curvature-point steel can consume energy after entering plasticity, and the damping ratio of the supporting component can be increased.
Furthermore, two ends of the web member are respectively welded on the upper chord member 1 and the lower chord member 2; the interlayer inclined strut 5 is welded on the lower chord 2; the welding mode is adopted to facilitate the manufacturing.
The utility model discloses in, stress ratio is one of them leading cause, still will be according to the superstrong and factors such as strain hardening of material, and the adjustment stress ratio is guaranteed direct web member and is buckled earlier.
The upper and lower parts of the utility model are the upper and lower parts in the conventional meaning with reference to the attached figure 1 of the specification.
It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
