Abstract
The invention discloses a connecting node for a wide-flange H-section steel column added with horizontal draw bars on two sides and an H-section steel beam. The connecting node comprises the H-section steel column and the H-section steel beam, wherein the H-section steel column is provided with a column web plate and column flanges located on two sides of the column web plate, the H-section steel beam is provided with a beam web plate and beam flanges located on two sides of the beam web plate, the connecting end of the H-section steel beam is connected with an end plate, a plurality of horizontal draw bars are arranged in the length direction of the H-section steel column, the horizontal draw bars located in the middle penetrate through the column web flanges and the end plate and then are fixed through frictional high-strength bolts, and longitudinal draw bars are connected among the adjacent horizontal draw bars penetrating the end plate. By the adoption of the structure, local bending of the flanges of the H-section steel column is effectively prevented from being destroyed, the local stability of the section steel flanges is improved, and connection of the beam-column node is achieved on the premise that the strength of the H-section steel column is reduced to the greatest extent. In addition, the end plate is welded to the end of the section steel beam, so that the node for connecting the beam and the column has good stretchability, natural vibration period of the structure is prolonged, amplitude is decreased, and vibration damage is reduced.
Description
Technical field
The invention belongs to building structure, especially a kind of beam-column connection.
Background technology
In high-rise steel structure, traditional H profile steel post edge of a wing is when thickness is less, section steel flange convex or concave is easily caused and buckling failure under load action, the bearing capacity of wide width wing edge H profile steel post and stability may be caused to decline, in order to ensure the local stability on the edge of a wing, common thinking strengthens frange plate thickness, but this can increase rolled steel dosage, increases construction cost and DeGrain.
Summary of the invention
Goal of the invention: provide a kind of wide width wing edge bilateral to add H profile steel post and the H profile steel beam connecting node of cross-tie, to solve the problems referred to above that prior art exists.
Technical scheme: a kind of wide width wing edge bilateral adds H profile steel post and the H profile steel beam connecting node of cross-tie, comprise: H profile steel post, there is column web and the post edge of a wing being positioned at described column web both sides, H profile steel beam, there is web and the flange of beam being positioned at described web both sides, the link of described H profile steel beam is connected with end plate, is provided with some cross-ties along on the length direction of described H profile steel post, is positioned at middle cross-tie and is fixed by frictional high-strength bolts through behind the post edge of a wing and end plate; Through end plate adjacent transverse pull bar be connected with longitudinal tie.
Further, described end plate and H profile steel beam are welded and fixed.
Further, corresponding punching on the post edge of a wing of described H profile steel post both sides, described cross-tie passes corresponding hole and is bolted.Described cross-tie spaced set, and symmetrical along H profile steel beam.
Beneficial effect: by said structure, the present invention both effectively prevent the destruction of H profile steel post edge of a wing cripling, improved the local stability of section steel flange, again under the prerequisite as far as possible reducing to weaken H profile steel post intensity, realized the connection of bean column node.Meanwhile, section steel beam welding edges end plate connection bean column node has good ductility, and the natural vibration period therefore increasing structure reduces amplitude, reduces earthquake.
Accompanying drawing explanation
Fig. 1 is that wide width wing edge bilateral of the present invention adds the H profile steel post of cross-tie and the structural representation of H profile steel beam connecting node embodiment.
Fig. 2 is that wide width wing edge bilateral of the present invention adds the H profile steel post of cross-tie and the lateral view of H profile steel beam connecting node embodiment.
Detailed description of the invention
As shown in Figure 1, the wide width wing edge bilateral of the embodiment of the present invention adds the H profile steel post of cross-tie and H profile steel beam connecting node mainly comprises H profile steel post 1 and H profile steel beam 2.Wherein, described H profile steel post 1 has column web 12 and is positioned at the post edge of a wing 11 of described column web both sides.Described H profile steel beam 2 has web 22 and is positioned at the flange of beam 21 of described web both sides, and the link of described H profile steel beam is connected with end plate 3, and end plate and H profile steel beam are welded and fixed.
Be provided with some cross-ties along on the length direction of described H profile steel post, be positioned at middle cross-tie and fixed by frictional high-strength bolts through behind the post edge of a wing and end plate; Through end plate adjacent transverse pull bar be connected with longitudinal tie 5.
The connected mode of cross-tie and channel column is incessantly a kind of, such as can in the following way: corresponding punching on the post edge of a wing of H profile steel post both sides, and cross-tie is through corresponding hole and be bolted.
In other embodiments, end plate can adopt other equivalent way to be fixed on the end of girder steel, such as one-body molded or be spirally connected.
During application, calculate the position punched in the sectional dimension of H profile steel beam column, shaped steel size, the edge of a wing according to actual condition, the size of pull bar size, and the thickness of end plate, make related accessory.Being welded to connect of hole, end plate and H profile steel beam on the H profile steel post edge of a wing and end plate can be prefabricated in advance in factory, and job site lifts.
In a word, applicant thinks as calculated with after test: in high-rise steel structure, the H profile steel post that choice for use edge of a wing bilateral adds cross-tie replaces traditional H profile steel post, edge of a wing bilateral adds the H profile steel post of cross-tie can with comparatively thin wing edge thickness, improve the weak axle rigidity of H profile steel post, and effectively prevent the destruction of H profile steel edge of a wing cripling, improve local stability and the bearing capacity of section steel flange.
Find when implementing: existing beam-column node type of attachment is not suitable for the H profile steel post that wide width wing edge bilateral of the present invention adds cross-tie and is connected with H profile steel girder connection simultaneously, it is a problem always thirsting for solving that the H profile steel post how wide width wing edge bilateral being added cross-tie is rationally connected with H profile steel beam, and the present invention in turn gives above-mentioned solution.
To sum up, the punching on the steel column edge of a wing of the present invention and beam end plate, the connection of pull bar can be prefabricated in the factory, and therefore on-site hoisting can improve construction quality, increases speed of application.Meanwhile, the H profile steel post that choice for use wide width wing edge bilateral adds cross-tie is connected with H profile steel girder connection and replaces existing beam-column node to connect, and can save steel and resource, can improve again the safety and stability of Column Joint in steel building.
More than describe the preferred embodiment of the present invention in detail; but the present invention is not limited to the detail in above-mentioned embodiment, within the scope of technical conceive of the present invention; can carry out multiple equivalents to technical scheme of the present invention, these equivalents all belong to protection scope of the present invention.It should be noted that in addition, each the concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode.
