Description

One and the non-orthogonal connected node of cross column and construction method
Technical field
The invention belongs to field of steel structure, be specifically related to a kind of and the non-orthogonal connected node of cross column and construction method.
Background technology
In many high-rise civil buildings, when structure height is higher or service load is larger, in order to reduce the size of column section, usually can use steel work and concrete compound section, i.e. profile steel concrete column, giving full play to bi-material advantage separately.The reinforcing bar of profile steel concrete column, in the majority with cross column, when enhancement Layer is in order to improve the horizontal rigidity of flooring, often use steel structure support, this supports general and profile steel concrete column and presents non-orthogonal states; Another when pillar and interior cylinder or inner pillar be not on same main shaft, the horizontal member of connection vertical member is just same with profile steel concrete column presents non-orthogonal states.
For the nonopiate connected node of cross column, still do not have solution preferably, cross column mainly disconnects by domestic prior art processing mode does junction plate transition; Or bottom flange correspondence position to do after stiffening rib welding steel between the edge of a wing again on beam, and then weld bracket and be connected with nonopiate component; Or junction plate gos deep into cross column web junction and connects.It is all larger that these three kinds of modes weld difficulty, manually drops into more, and weld seam overlap is intersected many, and welding stress is concentrated, and welding welding space is little, and it is large that machining accuracy controls difficulty, and profile steel concrete column vertical applied force reinforcing bar is connected complexity with the nonopiate component edge of a wing.
Because above-mentioned technical problem, the invention provides a kind of and the non-orthogonal connected node of cross column and construction method, this case produces thus.
Summary of the invention
The object of this invention is to provide a kind of and the non-orthogonal connected node of cross column and construction method, solve the nonopiate node weld difficulty of current cross column, weld seam is overlapping, and site operation positioning precision is difficult to the problems such as control.
In order to achieve the above object, the present invention is achieved through the following technical solutions:
One and the non-orthogonal connected node of cross column, comprise cross column and the orthogonal girder steel bracket be welded on cross column side face, be fixedly welded with annular connecting plate, described annular connecting plate is fixedly welded with horizontal member between adjacent girder steel bracket.
Further, described annular connecting plate two ends are fixedly connected with girder steel bracket by buttcover plate, and the both sides of each buttcover plate are also fixedly welded with stiffener.
Further, the cross web that described cross column comprises square crossing welding and the four pieces of edges of a wing be welded on cross web, reinforced by stiffening rib in corresponding position, the girder steel bracket edge of a wing between described cross web and the edge of a wing.
One and the non-orthogonal connected node construction method of cross column, comprise the steps:
One, girder steel bracket is welded on cross column side face; Two, butt welding plate on girder steel bracket, the buttcover plate correspondence on adjacent girder steel bracket is arranged; Three, buttcover plate both sides welding stiffener, and adopt fillet weld to connect with the edge of a wing of orthogonal girder steel bracket and web; Four, girder steel bracket welds with the cross column edge of a wing, and cross column stiffening rib is welded in corresponding position, bottom flange on girder steel bracket; Five, nonopiate horizontal member is welded on annular connecting plate; Six, annular connecting plate docks with buttcover plate at the construction field (site) and welds.
Beneficial effect of the present invention: described buttcover plate is welded on one block of plate on orthogonal girder steel bracket web, is mainly used to connect annular connecting plate, avoids stretching in annular connecting plate, strengthen in-site installation difficulty.
Described stiffener, in buttcover plate both sides, ensures that buttcover plate is stablized, strengthens ultimate bearing capacity of joints, and share the stressed of orthogonal girder steel bracket web.
Described annular connecting plate by with the welding of the buttcover plate on girder steel, realize and the connection between orthogonal girder steel bracket, nonopiate component can be avoided to be connected with the complexity of cross column.
Described annular connecting plate, avoids the exocuticle of profile steel concrete column, and when nonopiate component can be avoided directly to be connected with cross column, profile steel concrete column vertical applied force reinforcing bar is cut off by the edge of a wing and causes welding, installation difficulty etc.
In a word, the present invention changes nonopiate horizontal member and the weld seam between cross column between annular connecting plate with buttcover plate in orthogonal girder steel bracket weld seam by the mode of the external connection of annular connecting plate, reduce the weld seam quantity of cross column cross-point region, avoid low-angle little space welded seam, reduce weld seam overlapping, reduce node region welding difficulty, make node region weldquality be more prone to ensure.Joint structure is succinct, and force path is clear and definite, and easy to operate, efficiency is higher.

Fig. 1 is the general illustration of present pre-ferred embodiments;
Fig. 2 is the STRUCTURE DECOMPOSITION schematic diagram of present pre-ferred embodiments;
Fig. 3 is the floor map of present pre-ferred embodiments;
Fig. 4 is the embodiment of the present invention two structural representation.
Detailed description of the invention
By reference to the accompanying drawings, present pre-ferred embodiments is described in further details.
Embodiment one:
As Figure 1-3, a kind of and non-orthogonal connected node of cross column, the component related to comprises cross column 1, orthogonal girder steel bracket 2, nonopiate horizontal member 3, annular connecting plate 4, buttcover plate 5, stiffener 6.
Orthogonal girder steel bracket 2 and cross column 1 normal welding, buttcover plate 5 is welded on orthogonal girder steel bracket 2 web, and both sides stiffener 6 is strengthened, and nonopiate horizontal member 3 is welded on annular connecting plate 4, and annular connecting plate 4 welds with buttcover plate 5 at the construction field (site) again.
In the present embodiment, cross column 1 is generally profile steel concrete column inner cross post, generally at produce in factory.
Orthogonal girder steel bracket 2 is welded H section steel, length is general identical with orthogonal steel beam web plate height, then be rigidly connected with cross column 1, the cross web 11 that described cross column 1 comprises square crossing welding and the four pieces of edges of a wing 12 be welded on cross web 11, reinforced by stiffening rib 13 in corresponding position, the girder steel bracket edge of a wing between described cross web 11 and the edge of a wing 12.
Nonopiate horizontal member 3 is generally H profile steel or horizontal double angle, when being mainly used as enhancement Layer horizontal support, also can be pipe, rectangular tube uniform section, with cross column 1 oblique, connected by annular connecting plate 4, change nonopiate component 3 and the weld seam between cross column 1 into weld seam between annular connecting plate 4 with orthogonal girder steel bracket 2, reduce welding difficulty.
Buttcover plate 5 is welded on one block of plate on orthogonal girder steel bracket 2 web, is mainly used to connect annular connecting plate 4, avoids stretching in annular connecting plate 4, strengthens in-site installation difficulty.
