In the drawings, similar reference number can represented appropriate section in whole figure, and the description of appropriate section just can be omitted after in a single day providing.
Fig. 1 shows the part according to building frame of the present invention, and it has a plurality of steel pipe columns 20 to be connected in series with one heart.As shown in Figures 2 and 3, each bar post 20 is included in the steel pipe 22 that its inner surface 22a is coated with last layer separate layer 24, and has a core 26 to place within the steel pipe 22.The thickness range of steel pipe 22 be about steel pipe 22 external diameter 1/500 to about about 1/10.This separate layer 24 can be that a kind of barrier material is made, for example, and petroleum bitumen, grease, paraffin, synthetic resin and paper.Core 26 is made by structured packing, for example concrete, mortar, sand, glass grain, metal dust and synthetic resin.Separate layer 24 is not attached on the steel pipe 22 core 26 in order to steel pipe 22 and core 26 are separated.
In this embodiment, steel pipe 22 has a pipe shaft 28, and part therebetween, promptly moment of flexure turning point place provide one have that multirow runs through seam 32 run through seam part 30.As shown in Figure 2, the running through seam 32 mutual spaced at equal intervals in each row form circlewise running through seam part 30, and the position of running through seam in the vicinities of contiguous two row with the zigzag formula be offset.The summation (for example, in Fig. 2 running through seam on the dotted line VL) that runs through the upright width that runs through seam of the upright aligning that stitches part 30 is preferably in the scope of the axial maximum distortion that produces because of the overturning moment of building of steel pipe 22.The width of each bar seam 32 is to make the wall of each bar seam 32 that enough intensity is arranged, and it can not subsided because of axial compression during framework is built and is resisting static load.Stitch 32 except running through, other shaped aperture, such as elliptical openings, slit all can form on pipe shaft 28.
In this is built, from the shearing of beam 48 by beam connection 36,38,40 and 42 and the wall of tube connector 34 be delivered to inward flange 50 and 51.Then, shearing is delivered to core 26 from inward flange 50 and 51 and forms an axial force.Therefore, steel pipe 22 bears from beam 48 than core and the quite tiny axial force of coming.Because the existence of separate layer 24, steel pipe 22 can move axially with respect to core 26, and so when core 26 is subjected to axial compression, steel pipe 22 has more tiny axial deformation along with core 26 but linking its concrete core than steel pipe in the prior art.In addition, the axial compression of steel pipe 22 can see through to run through and running through of seam part 30 stitch axial deformation and reduce its axial length, therefore, the axial stresses in the steel pipe 22 is dissipated.
In building above-mentioned steel pipe column 20, structured packing, for example concrete for example transports concrete conduit through use and is filled within the steel pipe 22, to form core 26.At this filling process, inward flange 50 and 51 allows that conduit 54 is inserted within the steel pipe 22 along axis; This is to see through middle folder opening 50a and the 51a that as shown in Figure 4 conduit 54 is passed inward flange 50 and 51.Therefore, concrete 26 is fed to the center of steel pipe 22, on the entire cross section of steel pipe 22, distributes equably then.When the upper surface 26a of concrete 26 trends towards this dotted line from the level shown in the solid line of Fig. 4, air passes the center drilling 50a and the steam vent 52 of flange 50, and the annular air space 56 under inward flange 50 is filled by concrete 26; Then, the center drilling 50a of steam vent 52 and inward flange 50 is also filled by concrete.Any similar air space forms with the following 51b that same form is prevented from flange 51.As a result, steel pipe column that has the coupling part not have the air space that is occupied by concrete.
The improved form that has shown Fig. 3 embodiment in Fig. 5, the pipe shaft and the tube connector 58 that wherein do not have to show have square sectional.Though Fig. 5 only shows an inward flange, a pair of each have the inward flange 60 and 60 of a plurality of steam vents 52 to be welded to the inner surface 58C of tube connector 58 circlewise with the same form of inward flange 50 and 51; And in each inward flange 60, be formed centrally an octagon perforate 60a.
Another improved form of post among Fig. 2 and Fig. 3 shows at Fig. 6 and Fig. 7, wherein tube connector 34 has four reinforcing ribs 62 to be welded to inner surface 34C, and the wall 34b that makes reinforcing rib 62 see through tube connector 34 is connected to the web part 46 of respective beam connector 36,38,40 and 42.Reinforcing rib 62 is radially to the projecting inward core 26 that enters, and terminally relatively is connected with inward flange 50 and 51 at it.In this improves, can mainly be delivered to reinforcing rib 62 by tube connector 34 from the shearing of the web part 46 of beam connection 36,38,40 and 42.Then, shearing reaches core 26 by flange 50 and 51 from reinforcing rib.Therefore, because the existence of reinforcing rib 62, can be delivered to core 26 effectively, the inward flange 50 and 51 axial intensity of force of opposing that then acquisition is bigger than the inward flange of Fig. 2 and 3 from the shearing of beam 48.
Another improved form of the post that remains Fig. 2 and Fig. 3 that shows in Fig. 8 and Fig. 9, wherein the last end portion 64a of steel pipe 64 is provided with four beam connections 36,38,40 and 42.The inner surface 64b that a pair of inward flange 66 and 68 is welded to steel pipe 64 circlewise is positioned at the corresponding edge of a wing part 44 of connector 36,38,40 and 42 and 45 par place.Flange 66 and 68 and perpendicular to the plane inclination of the axis of steel pipe 64, and converge to upper limb 64a.The lower end of another steel pipe then is welded to the last terminal 64a of steel pipe 64 with one heart.Each piece flange 66 or 68 angle of inclination B are generally at zero degree to six ten degree.As angle B during near zero degree, the space of being filled by concrete may not produce below the outside of inward flange 66 and 68.If angle B is greater than 60 degree, just axial force can not be delivered to core 26 from each piece flange 66 and 68 effectively.Angle of slope B preferably is substantially equal to the angle of inclination of the upper surface 26a of concrete 26 when filling as shown in Figure 8.On show that the angle B of 26a can determine with the result of concrete slump test.
In the filling process of above steel pipe 64, can approach the soffit 66b of flange 66 and discharge to the central opening 66a of flange 66 along with concrete upper surface 26a at the upper surface 26a of concrete 26 and the air between the flange 66, pass opening 66a then along the soffit 66b of flange 66.In flange 68, air passes through central opening 68a with same form.Therefore, concrete 26 is filled the entire inner space of steel pipe 64, makes concrete core 26 not have air space and forms therein.
Angle of heel B can strengthen, as long as it allows that respective flanges 66 and 68 is delivered to core 26 with shearing.Angle B can also be made the angle of slope less than the upper surface 26a of concrete 26, this depends on concrete fluidity when filling.Except inward flange 66 and 68, straightforward face is trapezoidal, and its upper surface not have its soffit of inclination then can be welded on the inner surface 64b of steel pipe 64 with the inward flange perpendicular to the plane inclination of steel pipe 64 axis.
Figure 10 shows the improved form of inward flange 66 or 68, and wherein, inward flange 70 has a plurality of steam vents 52 to form with angular separation ground such as about circlewise, as shown in Figure 2 an inward flange 50 and 51.Steam vent 52 stretches upwards at steel shaft.The outer edge part that steam vent 52 is preferably in flange 70 forms, and makes when concrete is filled, through allow that air and cement pass and can not produce the space of not filled by cement below flange 70 in them.The air guiding groove that is linking steam vent 52 can form in the outer edge of the soffit of flange 70, and air is brought in the steam vent 52.
Figure 11 to Figure 13 shows an alternative embodiment of the invention.In Figure 11, many steel pipe columns 72 are connected in series to form a building frame.Every post 72 has steel pipe 74, and is provided with a coupling part 74a who is welding many beam connections 76 in the top.As shown in figure 12, the steel pipe 74 of per three sections posts 72 comprises pipe fitting 78 and the terminal with one heart following pipe fitting 80 that is soldered to the lower end of pipe fitting 78 on one thereon.The end portion of last pipe fitting 78 has the inward flange 82 that is welded on its inner surface 78a circlewise.Flange 82 has a plurality of its lower edges to be welded on the reinforcing rib 84 of upper surface 82a, and the radially outer edge of reinforcing rib 84 then is welded on the inner surface 78a of pipe fitting 78 as shown in figure 13.Promptly be that reinforcing rib 84 is connected to the inner surface 78a of pipe fitting 78 with the upper surface of flange 82, makes it resist an axial load intentinonally.On the other hand, the upper end of following pipe fitting 80 then is provided with and runs through seam part 30.Therefore, the steel pipe 74 of per three sections posts 72 is part therebetween, comprises that the moment of flexure turning point is provided with flange 82 and runs through seam part 30.
The modified form that the axial deformation of Fig. 2 absorbs structure 30 shows that in Figure 14 wherein, a plurality of cannelures 86 axially are formed equidistantly round the external surface 22C of steel pipe 22.Each bar groove 86 stretches in the whole circumference of steel pipe 22.The number of groove 86 and width C can be determined according to design condition seam 32 ground as shown in Figure 2 of every post 20.The thickness D of the end wall of every groove 86 will make end wall that sufficient intensity opposing axial compression is arranged when framework is built and resists load when static.When axial compression was added on the steel pipe 22, the width C of every groove 86 can be dwindled.Therefore, groove 86 has absorbed the axial deformation in steel pipe 22 and its stress that dissipates.Except groove 86, can also on the inner surface 22a of steel pipe 22, form groove 88 as shown in figure 15.
Another kind of axial deformation absorbs structure 30 and shows that in Figure 16 the inner surface radial direction of the part of steel pipe 22 outwards protrudes, thereby protrudes a corrugated portion 90 from steel pipe 22.Wall spare 94 corrugated portion 90 of packing between one annular is with the inside of corrugated portion 90 enclose inside from steel pipe 22; Thereby between the inner surface of a wall spare and corrugated portion 90, delimit an annular air space 92; Therefore, prevented that concrete 26 from entering air space 92.This wall spare 94 can be made by elastomeric material, for example pitch, rubber, lead and aluminium.This corrugated portion 90 is the meeting axial deformation when axial compression is added to steel pipe 22, therefore, and the axial stress in the steel pipe 22 that dissipated.
