As shown in Figure 3; Earlier foundation columns 5 is placed on the intersection point of the transverse axis (X axle, Y axle) and the longitudinal axis (A axle, B axle, D axle and E axle); Again transverse truss 1 is lifted on the foundation columns 5; The two ends of one Pin transverse truss 1 are placed on respectively on the corbel 51 of the foundation columns 5 that is positioned at X axle and D axle and B axle intersection point, the two ends of another Pin transverse truss 1 are placed on respectively on the corbel 51 of the foundation columns 5 that is positioned at Y axle and D axle and B axle intersection point.Mounting slip beam 52 on the corbel 51 of foundation columns 5; Four slippage beams 52 lay respectively on the line of intersection point of X axle and A axle and B axle; On the line of the intersection point of X axle and D axle and E axle, on the line of the intersection point of Y axle and A axle and B axle, on the line of the intersection point of Y axle and D axle and E axle.The upper surface of the upper surface of slippage beam 52 and transverse truss 1 is positioned on the same horizontal plane.Again at the upper surface longitudinal central axis of slippage beam 52 and the top longitudinal central axis line upper mounting rail 53 that winds up of transverse truss 1.
As shown in Figure 4, first longitudiual truss 2 that two Pin are welded to connect with two first support columns 21 respectively in advance lifts respectively and is positioned at A axle and B axle, and four first support columns 21 lay respectively on the foundation columns 5 on A axle and the B axle.Two first support columns 21 that are positioned at the X axle are welded to connect through two linking beams 22, and two first support columns 21 that are positioned at the Y axle also are welded to connect through two linking beams 22.First support column 21 is welded to connect through the support bar 24 that tilts with linking beam 22.Like this two Pin, first longitudiual truss 2 and four first support columns 21 are connected into an integral body, stability is more intense when can make slippage.The pulley 23 that matees with guide rail 53 is installed in the bottom of four first support columns 21.
As shown in Figure 5, four first support columns 21 and two Pin, first longitudiual truss 2 are whole along the guide rail 53 on the top longitudinal central axis line that winds up of upper surface longitudinal central axis that is installed in slippage beam 52 and transverse truss 1, whole to D axle and the slippage of E axle.With four first support columns 21 and two Pin, first longitudiual truss, 2 integral slippings to D axle and E axle.Use jack, with first longitudiual truss 2 and first support column, 21 whole jack-up, dismounting pulley 23, track 53 and slippage beam 52 dock welding with first support column 21 on top with the foundation columns 5 of bottom.
As shown in Figure 6, second longitudiual truss 3 that two Pin are welded to connect with two second support columns 31 in advance lifts respectively and is positioned at A axle and B axle.Four second support columns 31 lay respectively on the foundation columns 5 on A axle and the B axle.Two second support columns 31 that are positioned at the X axle are welded to connect through two linking beams 22, and two second support columns 31 that are positioned at the Y axle also are welded to connect through two linking beams 22.Second support column 31 is welded to connect through the support bar 24 that tilts with linking beam 22.Second support column 31 on top is docked welding with the foundation columns 5 of bottom.
As shown in Figure 7, at the top of two first support columns 21 of two second support columns that are positioned at the B axle 31 and D axle steel strand jack 6 is installed respectively.The steel strand 61 of steel strand jack 6 are connected with transverse truss 1, and the support afterbody of steel strand jack 6 utilizes steel wire 62 to be connected with linking beam 22 simultaneously, is used for the support of balance steel strand jack 6.
As shown in Figure 8, start steel strand jack 6, transverse truss 1 is promoted to setting height.With transverse truss 1 and corresponding first support column 21 and the welding of second support column, 31 counterparts.
So far, using transverse truss 1, first longitudiual truss 2 and second longitudiual truss 3 to accomplish the slippage of truss self-bearing type promotes.
In embodiment 1, transverse truss 1, first longitudiual truss 2 and second longitudiual truss 3 all adopt the shaped steel truss.In other embodiments, also can adopt other truss such as timber truss or reinforced concrete truss.
In embodiment 1, first support column 21 and second support column 31 all are steel columns.In other embodiments, also can be pin or reinforced concrete post.
In embodiment 1, the quantity of transverse truss 1, first longitudiual truss 2 and second longitudiual truss 3 all is two Pin.In other embodiments, the quantity of transverse truss 1, first longitudiual truss 2 and second longitudiual truss 3 also can be a Pin, three Pin or four Pin etc.If transverse truss 1 is a Pin, need coming together by other crossbeam, support first longitudiual truss 2 slides.If the quantity of first longitudiual truss 2 is more than two Pin, because tie point increases, need more firm connection, could guarantee the stability of slippage.
Above-described only is embodiments more of the present invention.For the commonsense method personnel of this area, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, these all belong to protection scope of the present invention.
