Detailed description of the invention
below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to any restriction of the present utility model.
the utility model is that this type of attachment is the improvement to existing post and beam structure, and the connection of Liang Yuzhu all adopts welded corner joint connected mode constructed by following a kind of girder steel and the weak axial type of attachment of I-shaped cross-section post; Specific practice is: after girder steel is inserted into the weak axial groove of I-shaped cross-section post, on beam-ends top flange is passed through, three weld all arounds of horizontal connecting plate and steel column are connected, be connected with three weld all around steel columns by lower horizontal connecting plate in beam-ends bottom flange, two edges of a wing and the upper and lower horizontal connecting plate of girder steel adopt three weld all around modes to be connected.Upper and lower horizontal connecting plate is rectangular slab, and rectangular slab avoids the inner arc surface of steel I-column by chamfering.Steel I-column web between upper and lower horizontal connecting plate is provided with vertical center web, and vertical center web plate is provided with one group of fixing hole; The web of girder steel is provided with one group of fixing hole corresponding with vertical center web, and girder steel is welded after being located by connecting by bolt assembly again.
the of the present utility model a kind of girder steel formed as stated above and the beam-to-column joint structure of I-shaped cross-section post are that this beam-to-column joint structure comprises steel I-column 1 and girder steel 2, are provided with horizontal connecting plate 3 and lower horizontal connecting plate 4 on the girder steel end edge of a wing; Steel I-column 1 web between upper horizontal connecting plate 3 and lower horizontal connecting plate 4 is provided with vertical center web 5, and the termination of girder steel 2 is between upper horizontal connecting plate 3 and lower horizontal connecting plate 4 and be located by connecting through bolt assembly 8 and vertical center web 5; Upper horizontal connecting plate 3 and lower horizontal connecting plate 4 and steel I-column 1 three weld all arounds, the wing plate width of girder steel 2 is less than steel I-column web height.The web of girder steel 2 is slightly shorter than wing plate, and web is provided with fixing hole 12.One side of vertical center web 5 and the web of girder steel 2 are fitted, and are located by connecting through bolt assembly 8 and vertical center web 5.
Embodiment
this example is the improvement to existing bean column node, easy construction.As depicted in figs. 1 and 2, beam and column is i-beam structure to existing bean column node.Horizontal connecting plate 3 and lower horizontal connecting plate 4 is welded with between two wing plates of steel I-column 1 side, distance between upper horizontal connecting plate 3 with lower horizontal connecting plate 4 is corresponding with the distance between the upper and lower wing plate of girder steel 2, the upper flange of girder steel 2 docks with upper horizontal connecting plate 3, the lower wing plate of girder steel 2 docks with lower horizontal connecting plate 4, docking mode beats groove 6 on the wing plate of girder steel 2, bottom horizontal connecting plate and wing plate, pad one piece of run-on tab 7 during welding, then with welding rod, the gap between horizontal connecting plate and wing plate is filled and led up.Existing beam column docking mode welding quality requires high, and difficulty of construction is large.
this example improve one's methods as shown in Figure 3 and Figure 4, after girder steel is inserted into the weak axial groove of I-shaped cross-section post, on beam-ends top flange is passed through, three weld all arounds of horizontal connecting plate and steel column are connected, be connected with three weld all around steel columns by lower horizontal connecting plate in beam-ends bottom flange, upper and lower horizontal connecting plate and steel I-column adopt three weld all arounds to be connected, and concrete welding position is as shown in the label B in Fig. 5.Upper horizontal connecting plate 3 is connected one side and only adopts one side fillet welding to connect at end face with steel I-column 1 web, bottom is not welded.Concrete welding position is as shown in the label C in Fig. 5.Can ensure that girder steel 2 is inserted into the end and steel I-column 1 web close contact.Lower horizontal connecting plate 4 is connected with steel I-column 1 web and on one side only adopts one side fillet welding to connect in bottom surface, inserts top do not weld for avoiding affecting girder steel 2.Then steel I-column 1 web between upper and lower horizontal connecting plate welds one piece of vertical center web 5, vertical center web 5 can not be welded on the centre of steel I-column 1 web, should be more slightly biased, with ensure the termination of girder steel 2 insert rectangular recess after vertical center web 5 fit with the web of girder steel 2.Vertical center web 5 and steel I-column 1 web adopt butt welding.Vertical center web 5 is provided with two fixing holes, is first fixedly connected with the fixing hole of two on vertical center web 5 12 by two fixing holes 12 on girder steel 2 web with bolt assembly 8, girder steel is located after rectangular recess is inserted in the termination of girder steel 2.And then two wing plates of girder steel and upper and lower horizontal connecting plate are welded together.Because girder steel is inserted in the rectangular recess between upper and lower horizontal connecting plate, therefore forming step between girder steel wing plate and upper and lower horizontal connecting plate, adopt one side welded corner joint mode to connect at step place, concrete welding position is as shown in the label A in Fig. 3.After above-mentioned improvement, the connection eliminating prior art flange of beam and post adopts the groove butt weld of the complete penetration being provided with run-on tab to connect, do not need to beat groove 6 on the wing plate of girder steel 2, do not need to pad run-on tab 7 bottom horizontal connecting plate and wing plate yet, owing to adopting welded corner joint and step welding manner, welding difficulty reduces greatly, and welding quality is also greatly enhanced, and therefore also improves the feasibility of post and beam structure.
the supplementary notes of the present embodiment
in order to avoid the weld seam of vertical center web, the web of girder steel 2 termination should excise, and makes the web of girder steel 2 termination slightly shorter than wing plate.So just girder steel 2 termination can be inserted into the end, the wing plate of girder steel 2 termination and steel I-column 1 web are pushed against, to guarantee welding quality.
in order to ensure steel I-column 1 intensity, horizontal reinforcing plates 9 is welded with between two wing plates of steel I-column 1 opposite side, horizontal reinforcing plates 9 and horizontal connecting plate are rectangular slab, in order to avoid the interference of steel I-column 1 Inner arc to horizontal reinforcing plates 9 and horizontal connecting plate, chamfering 11 can be set at the drift angle of horizontal reinforcing plates 9 and horizontal connecting plate.
when girder steel 2 is assembled with steel I-column 1, first by crane gear, girder steel 2 termination is inserted in the weak axle groove of steel column, girder steel 2 and steel I-column 1 are located by connecting by bolt assembly 8, and then weld, concrete welding procedure welded corner joint technique routinely performs.
