When the stand just connects with the horizontal component, take the plate girder as the example, the deformation of plate girder under the effect of the dead weight of structure can lead to the stand to follow take place to warp, in order to resist the deformation of roof beam, perhaps bear the moment of flexure that the roof beam transmitted, the post often need design very big very thick for with the steel volume grow and do not have the aesthetic feeling. If the columns are hinged with the horizontal members (the horizontal members comprise beams or plates or plate trusses and the like), although the deformation of the beams does not affect the columns, the columns and the beams cannot form a frame, the structure becomes a bent structure, the lateral stiffness of the bent structure is far smaller than that of the frame structure, and therefore the columns also need to be designed to be large and thick to meet the requirement of the lateral stiffness of the structure.

The invention is described in detail below with reference to the figures and specific embodiments. It is noted that the aspects described below in connection with the figures and the specific embodiments are only exemplary and should not be construed as imposing any limitation on the scope of the present invention.
Referring to fig. 1 to 5, the present invention is directed to solving the problem that in the existing horizontal structure such as cantilever and large span, the horizontal member is deformed due to a corner caused by dead weight, so that the supporting structure bears a large bending moment, and needs to be designed into a large cross section, and a connection node between the vertical column and the horizontal member is provided, wherein the connection node comprises a horizontal member 1 and a vertical column 2, the top of the vertical column 2 is provided with a hinge point, and the hinge point is supported at the bottom of the horizontal member 1 and is hinged to the horizontal member 1; a rotatable gap 23 for blocking the horizontal member 1 from transmitting bending moment to the upright 2 is arranged between the top of the upright 2 and the bottom of the horizontal member 1, and a rear rigid connection node 24 is arranged in the rotatable gap 23.
Preferably, the horizontal member is a beam or a plate truss. In the present embodiment, a plate truss is specifically described as an object.
What need show is, among the bearing structure of traditional horizontal component and stand, no matter be the girder steel of encorbelmenting of plate truss or large-span, thereby the horizontal component can take place deformation transmission moment of flexure to the stand because of the dead weight, lead to the stand and then take place to warp, in order to resist the deformation of roof beam, perhaps bear the moment of flexure that the roof beam transmitted, the post often needs to design very big very thick for become with the steel volume and do not have the aesthetic feeling, and if avoid the stand to warp through the hinge, the anti lateral stiffness of structure is again far away not enough. Therefore, when the horizontal member is installed, the upright posts are prevented from being deformed due to the bending moment transmitted by the horizontal member through the hinge joint; after the horizontal component is installed and the self deformation of the horizontal component caused by self weight is finished, the lateral stiffness of the upright column is improved through rigid connection, so that the stability of the whole structure is improved, and the upright column can adopt thinner thin columns through the design, so that the steel consumption is reduced, and the whole aesthetic feeling is improved (compared with common support columns in building structures, the thin support upright columns can break visual cognition to cause strong visual impact).
The hinge point is intended to transmit vertical force of the horizontal member 1 to the column, and when the structure in this embodiment is loaded by gravity, only vertical force is transmitted between the horizontal member 1 and the column, and no bending moment is transmitted, and the connection can rotate without restriction. Therefore, the hinge point can be a hemisphere 22, and the top of the column 2 is provided with a first groove 21 for placing the hemisphere 22. The hemisphere 22 supports the horizontal member 1 and forms a rotatable gap 23 between the horizontal member 1 and the top of the column, so that the bending moment of the horizontal member 1 is not transmitted to the column, and stress deformation and damage are not caused to the connection node and the column of the column.
As another embodiment of this embodiment, please refer to fig. 6 and 7, the hinge point may also be a supporting screw 25, and the top of the upright 2 is provided with a threaded slot 26 for the supporting screw 25 to be connected and the height to be adjusted. The supporting screw 25 is supported on the horizontal member 1, and the height of the supporting screw 25 in the threaded slot 26 can be adjusted adaptively. The same as the above-mentioned hemisphere 22 embodiment is that the supporting screw 25 is supported at the bottom of the horizontal member 1, so that a rotatable gap 23 is formed between the horizontal member 1 and the top of the pillar, thereby blocking the bending moment transmission of the horizontal member 1 and protecting the connection node and the pillar of the pillar.
After the corner deformation of the horizontal member 1 is finished, the rear rigid connection node 24 is additionally arranged to connect the horizontal member 1 and the upright post 2, so that an integrally stable frame structure is formed, the lateral stiffness of the horizontal member and the upright post is improved, and the lateral resistance and the stability of the structure are improved in earthquake and wind resistant environments. At the moment, the corner deformation of the horizontal component 1 is finished, the transmitted bending moment is greatly reduced, and the stress deformation of the upright column (thin column) is also reduced to the minimum. And correspondingly, grooves are formed around the upright columns 2, and the grooves and the horizontal members 1 are subjected to groove welding to form the rear rigid connection nodes 24.
In view of the above, the present invention also provides a method for constructing a connection node between a vertical column and a horizontal member, including:
s1: the top of the upright post 2 is provided with a hinge point, the horizontal member 1 is arranged on the hinge point, a rotatable gap 23 is reserved between the bottom of the horizontal member 1 and the top of the upright post 2, and the horizontal member 1 is blocked from transmitting bending moment to the upright post 2.
Specifically, the hinge point provides two embodiments in this embodiment:
firstly, the hinge point can be a hemisphere 22, and the top of the upright 2 is provided with a first groove 21 for placing the hemisphere 22. The semi-sphere 22 supports the horizontal member 1 and forms a rotatable gap 23 between the horizontal member 1 and the top of the pillar, so that the bending moment of the horizontal member 1 is not transmitted to the pillar, and further the stress deformation and damage to the connection node and the pillar of the pillar are avoided.
Secondly, the hinge point can also be a supporting screw 25, and the top of the upright post 2 is provided with a threaded groove 26 for connecting the supporting screw 25 in a threaded manner and adjusting the height. The supporting screw 25 is supported on the horizontal member 1, and the height of the supporting screw 25 in the threaded slot 26 can be adjusted adaptively. The same as the above-mentioned hemisphere 22 embodiment is that the supporting screw 25 is supported at the bottom of the horizontal member 1, so that a rotatable gap 23 is formed between the horizontal member 1 and the top of the pillar, thereby blocking the bending moment transmission of the horizontal member 1 and protecting the connection node and the pillar of the pillar.
Preferably, grooves are formed around the upright post 2 so as to facilitate the subsequent welding of the rigid connection node 24.
S2: temporary supports are provided for the overall structural mounting on the horizontal member 1. Horizontal component 1 can be board, board truss or roof beam, and when carrying out overall structure installation, horizontal component 1 takes place the corner deformation, and at this moment, rotatable clearance 23 and pin joint block horizontal component 1 moment of flexure and transmit to stand 2, protect stand 2, also so, stand 2 can choose for use the size to be far less than the thin post of conventional stand and accomplish the support.
S3: after the integral structure on the horizontal member 1 is installed, the temporary support is removed, and after the horizontal member 1 is subjected to corner deformation, a rear rigid connection node 24 is formed in the rotatable gap 23 to connect the upright 2 with the bottom of the horizontal member 1. Further, the rear rigid connection node 24 may be formed by welding between the groove and the bottom of the horizontal member 1.
The invention has the beneficial effects that:
in the supporting structure of the traditional horizontal member and the upright, the upright is either rigidly connected or hinged with the horizontal member. During rigid coupling, thereby because of the horizontal component can take place deformation transmission moment of flexure to the stand because of the dead weight, lead to the stand to follow take place to warp, in order to resist the deformation of roof beam, perhaps bear the roof beam and transmit the moment of flexure of coming, the post often need design very big very thick for with the steel volume grow and do not have the aesthetic feeling, and if avoid the stand to warp through the hinge, the anti side rigidity of structure is not enough again far away. Therefore, when the horizontal member is installed, the upright posts are prevented from being deformed due to the bending moment transmitted by the horizontal member through the hinge joint; after the horizontal member is installed and the self deformation of the horizontal member due to self weight is finished, the lateral stiffness of the upright post is improved through rigid connection, so that the stability of the whole structure is improved.
While the present invention has been described in detail and with reference to the embodiments thereof as illustrated in the accompanying drawings, it will be apparent to one skilled in the art that various changes and modifications can be made therein. Therefore, certain details of the embodiments are not to be interpreted as limiting, and the scope of the invention is to be determined by the appended claims.
