Description
Technical field
The present invention relates to the spatial steel structure connected node, refer to that specifically a kind of square-section steel member reverses the welding tubular joint that crosses.
Background technology
In steel building, the steel member formation node that crosses.Node plays the effect of coordinating member stress and distortion, to guaranteeing that structural safety is significant.In the modern space structural steelwork, directly pass through the node that constitutes of welding mutually because simple appearance, power transmission are clear and definite by the steel member, so often be used.
The steel member section form that often adopts in the steel building is by remaining silent of forming of steel plate spelling or opening mostly, and the cross section outline is the cross section of rectangle (also comprise square, H shape etc.).
In the building of body rule; The square-section member is accomplished directly to pass through mutually not so difficult at the joint place, because the edge of a wing steel plate of all directions steel member can coplane or be parallel, if particularly vertically the steel member is identical with the depth of section of horizontal steel member; Then their the upper and lower edge of a wing is respectively on same horizontal plane; Can directly pass through welding mutually, the web of both direction also can be realized total cross-section welding in intersection, and this is a more satisfactory welding node that passes through mutually.
Along with the architectural design style is gradually various, the outward appearance of more and more buildings presents inclined-plane, folding face even warp surface, when steel work is used to construct these structures; Member often is obliquely installed, and the member that meets at so together will form the just comparison difficulty of node of directly passing through mutually: the edge of a wing is coplane not, even also not parallel; If adopt the mode of directly passing through welding mutually; Just have partial cross section welding less than together, such tubular joint is given the unsafe impression of people on impression, and its mechanical property also has problem; Be difficult to reach the rigidly connected effect of supposition when designing, weakened the degree of safety of node.
The following three kinds of methods of general employing solve this problem in actual engineering:
1, adopts cast steel node.Cast steel node can be made into the shape of external surface distortion, aligns with the steel member of different directions respectively in the joint.But the wall thickness of cast steel node is big than the wall thickness of welding node, thus its steel using amount greater than welding node, simultaneously the unit price of cast steel exceeds general steel plate, so that the cost of cast steel node exceeds than welding node is more.The fabricating quality of cast steel node more is difficult to control than the fabricating quality of welding node, and defects detection is also relatively more difficult.In addition, cast steel node weight is bigger, and this is very disadvantageous for the space structures to the sensitivity of conducting oneself with dignity.So except a small amount of key project, general data is seldom used cast steel node.
2, adopt the node region that strengthens.By strengthening the method for node region outer profile size, the feasible steel member that crosses reverses howsoever or tilts and can both realize the total cross-section welding with node.More common measure is to adopt sphere nodes; For let all steel members all with the welding of the external surface of sphere nodes; The diameter of sphere nodes can be bigger, looms large in its outward appearance total, is difficult to obtain architect and owner's approval in the time of therefore many.And this node need use slab could guarantee the bearing capacity and the rigidity of node, and the price of slab is higher, and mechanical property is poor, and welding will adopt special technology just can ensure the quality of products, and welder's technical level is had relatively high expectations.This category node weight is also bigger, and is very unfavorable for space structures.
3, adopt curved slab.Roasting or make plane steel plate become curved surface crooked or that reverse with fire with the method that machinery rolls, with the welding of frange plate up and down of steel member of crossing of aliging respectively of the edge of curved slab.This node does not increase the weight of node, does not enlarge the volume of nodes domains.Its shortcoming is to adopt the roasting method of fire to make steel plate bending or reverses the difficult control of this technology, often does over again, and the steel plate after the roasting distortion is uneven, and the expense of the roasting bent plate of fire is higher, and the duration is also longer, so this method seldom adopts.The machinery roll bending just relates to the cost issues of mould, and the node of using in the construction work is elongated all to be unique, adopts this method cost too high.
4, change the node connected mode.The steel member of a direction is continuous such as letting, and the steel member of direction breaks off outside node area in addition, need not pass through welding mutually, but part ways of connecting such as employing plate.It is hinged to adopt this way that the steel member of disconnection is become at the node place, has reduced the rigidity of structure like this, under load action malformation bigger, and then if the controlled deformation amount can increase the steel using amount of structure again.
Summary of the invention
The object of the invention is exactly for overcoming the deficiency of existing method, the torsion crossed welding intersected node of steel component with rectangular cross section that a kind of affixed characteristic that does not change tubular joint is provided, do not influence impression, deadweight is little, cost is low.

Said vertical steel member is with laterally the steel member is with wide, and the cross section is with high.
In order to guarantee the safety of node, the thickness that constitutes landing edge and the steel plate of two transverse joints is taken as 1.5 times of maximum thickness of slab in horizontal steel member and the vertical steel member.
With respect to prior art, the present invention has following advantage and beneficial effect:
(1) can adapt between the square-section member that crosses and reverse angle, and the also uneven situation of coplane not of the edge of a wing each other;
(2) cost is low; Address the above problem if adopt cast steel node or strengthen node region, can enlarge the outer profile size of node, also will use than steel plate, its steel using amount and cost all obviously increase.And welding node steel using amount of the present invention is little and technology is simple, so cost is low;
(3) deadweight is little; The steel using amount of node of the present invention is identical with the steel using amount that does not reverse the node that crosses; Compared to adopting cast steel node and strengthening the node region outer profile size; Adopt the way than steel plate simultaneously, it is light that weight is wanted, so the deadweight of adopting node of the present invention can alleviate node;
(4) do not increase the node outline, do not influence impression; The welding node zone is to be processed by vertical and horizontal quadrangular plan steel plate, it with intersect similar to member shape (can be square, rectangle, H shape, T shape) in length and breadth, can not increase the node outline does not influence impression yet.
(5) do not change the affixed characteristic of tubular joint; Through node of the present invention in length and breadth to joint, two-way steel member can accomplish that total cross-section passes through welding mutually, thereby has guaranteed the affixed characteristic of member in node intersection;
(6) technology is simple, easy master; Node of the present invention adopt flat board and flap---also can be decomposed into two flat boards---welding processing forms, and does not adopt special process, so simple, be prone to grasp.
