Below in conjunction with accompanying drawing 2 to accompanying drawing 9, describe the steel column drum rack alternating bracing hydraulic of one embodiment of the invention integral steel platform that climbs in detail and cross girders layer construction method, comprise the following steps:
Step a: as shown in Figure 2, original state is that steel column drum rack alternating bracing hydraulic climbs that to be positioned at Core Walls Structure 6 top of concrete of firm casting complete high with last layer for integral steel platform 100;
As shown in Figure 3 and Figure 4, rely on the shear wall of the Core Walls Structure 6 be poured, utilize steel column to support 22 and steel plateform system 1 is risen to the first predetermined altitude;
Specifically, as shown in Figure 3, flexible bracket 213 exits Core Walls Structure reserved opening 7, and steel column supports 22 and is fixed on Core Walls Structure 6 concrete structure upper end, as the support of whole steel platform formwork system, control alternately climbing of climbing boots 31 by hydraulic system 32 and realize climbing of steel platform, climb after putting in place, flexible bracket 213 is stretched into Core Walls Structure reserved opening 7, carry out stress check calculation, then, as shown in Figure 4, control climbing boots 31 by hydraulic system 32 oppositely to climb and steel column is supported 22 times carry.
Step b1: as shown in Figure 5 and Figure 6, remove the part steel deck-plate 14 and coupling beam 12 of interferenceing with girders layer, channel floor steel platform is made to form cavity 15 (being shown as oblique line frame in figure), part lower chord assembly 911 is hung in Core Walls Structure 6 from cavity 15, and part lower chord assembly 911 is interconnected and fixes with the shear wall of Core Walls Structure 6;
Lower chord assembly 911 is specially with the fixed connection method of the shear wall of Core Walls Structure 6: be first poured in the shear wall of Core Walls Structure 6 by part lower chord assembly 911, connector can certainly be buried by arranging in the shear wall of Core Walls Structure 6, then part lower chord assembly 911 is connected with built-in connection, to reach the object be fixedly connected with shear wall.
Because the weight of coupling beam 12 carrying leg hand system 4 and template system 5, and steel deck-plate 14 and coupling beam 12 are also constructed as operation platform, in order to ensure the safety of constructing, in this step b, part steel deck-plate 14 and coupling beam 12 can only be removed, all steel deck-plates 14 and coupling beam 12 all can not be removed.In addition, also there is no need all steel deck-plates 14 and coupling beam 12 to remove, under the premise that security is guaranteed, only need to remove part and there is the steel deck-plate 14 and coupling beam 12 of mutually interfering with the installation site of girders layer.
In order to improve efficiency of construction, under the prerequisite ensureing stress equalization, in step b1, also can remove the part steel deck-plate 14 on two steel platform unit 11 and coupling beam 12 simultaneously, in order to ensure stress equalization, the steel platform unit 11 be removed requires to be symmetric with the center of Core Walls Structure 6, and two the steel platform unit showing dismounting in Fig. 5 and Fig. 6 are positioned on the diagonal of whole steel platform 13.
Step b2: described for the part of removing in step b1 steel deck-plate 14 and described coupling beam 12 are recovered install;
Step b3: as shown in Figure 7, repeat above-mentioned steps b1 to step b2, substep removes all steel deck-plates 14 of interferenceing with girders layer and coupling beam 12, lower chord assembly 911 substep is hung in Core Walls Structure 6, and all lower chord assemblies 911 are connected to form lower chord 91;
Equally, ensure stress equalization to improve efficiency of construction simultaneously, can remove simultaneously and be symmetric part steel deck-plate 14 on two each steel platform unit 11 and coupling beam 12 with the center of Core Walls Structure 6 by substep, and the lower chord assembly 911 of correspondence position substep is hung in Core Walls Structure 6, and the lower chord assembly 911 of this part is connected and is fixedly connected with the shear wall of Core Walls Structure 6, and then the steel deck-plate 14 be removed and coupling beam 12 are recovered to install, repeat above-mentioned steps, progressively all lower chord assemblies 911 substep is hung in Core Walls Structure 6, and all lower chord assemblies 911 are connected to form lower chord 91.
Should be understood that, the order that substep removes steel platform unit can sort flexibly according to the actual needs of site operation, and the present invention does not limit dismounting order.Preferably, in order to improve efficiency of construction, dismounting operation can be carried out to two steel platform unit simultaneously, but in order to stress equalization consideration, require that two the steel platform unit simultaneously carrying out removing operation are symmetric with the center of Core Walls Structure.Certainly, when the One's name is legion of steel platform unit, in order to improve efficiency of construction, also can carry out dismounting operation to plural steel platform unit simultaneously, consider stress equalization, require that the steel platform unit simultaneously carrying out removing operation is symmetric with the center of Core Walls Structure.
Further, when after lower chord 91 installation, original concrete segmentation lifts assembling reinforcement, then by contraposition bolt, template system 5 is arranged on the both sides of described Core Walls Structure 6 structure, then carries out concrete structure pouring and maintenance; After concrete curing terminates, template system 5 is removed and under be hung on the below of steel plateform system 1, prepare lifting and do one's assignment.
Through step b1 to step b3, complete the installation of lower chord 91, in above-mentioned installation process, installer all under be hung on below steel plateform system 1 pin hand system 4 on complete, in order to ensure that installation has enough construction spaces, preferably, require that the distance that the first predetermined altitude in step a is higher than lower chord 91 absolute altitude is 1400mm ~ 1800mm, carry out construction operation to facilitate workman.
Step c: rely on the shear wall of Core Walls Structure 6 be poured, utilizes steel column to support 22 and to be climbed by institute's steel column drum rack alternating bracing hydraulic integral steel platform 100 second predetermined altitude;
Specifically, similar to steel column drum rack alternating bracing hydraulic process of climbing in integral steel platform 100 process and step a of climbing, do not repeating at this.
Steps d: as shown in Figure 8, removes the part steel deck-plate 14 and coupling beam 12 of interferenceing with girders layer, makes channel floor steel platform form cavity, hung in Core Walls Structure 6 by part diagonal web member assembly from cavity, and be fixedly connected with lower chord 91 by part diagonal web member assembly;
Usually, girders layer is all made up of lower chord, diagonal web member and upper chord.The concrete grammar that climbs of integral steel platform and steel column drum rack alternating bracing hydraulic climbs, depend on climb stroke and the practice of construction scheme of hydraulic system, the height that integral steel platform once climbs if steel column drum rack alternating bracing hydraulic climbs is larger, each assembly of diagonal web member and upper chord can be fitted together in advance, if diagonal web member assembly and upper chord assembly fit together in advance, in this steps d, diagonal web member assembly can be hung in Core Walls Structure together with upper chord assembly simultaneously.Usually, because execution conditions more complicated, steel column drum rack alternating bracing hydraulic climbs all not too large of height that integral steel platform once climbs, at this moment needs substep that diagonal web member assembly and upper chord assembly are hung in Core Walls Structure.Special in super highrise building, the steel column drum rack alternating bracing hydraulic integral steel platform that climbs climbs process complexity, each walks the height climbed and is subject to a lot of restriction, sometimes only also need to split layering lifting for diagonal web member, such as, diagonal web member assembly can be split long two groups of diagonal web member assemblies composition: the first diagonal web member assembly and the second diagonal web member assembly be positioned on the first diagonal web member assembly.For this situation, the method that two steps can be adopted to promote completes, and concrete construction method is as follows:
First, as shown in Figure 8, remove the steel deck-plate 14 of interferenceing with girders layer and coupling beam 12 step by step, make channel floor steel platform 13 form cavity, part first diagonal web member assembly 921 hangs in Core Walls Structure 6 by substep, is fixedly connected with lifting the first diagonal web member assembly 921 put in place with truss lower chord 91; Wherein, after each step dismounting installation terminates, all the steel deck-plate 14 be removed in this step and coupling beam 12 to be recovered to install;
Then, as shown in Figure 9, rely on the shear wall of Core Walls Structure 6 be poured, utilize steel column to support 22 integral steel platforms that to be climbed by steel column drum rack alternating bracing hydraulic and rise to the 3rd predetermined altitude;
Then, as shown in Figure 10, remove the steel deck-plate 14 of interferenceing with described girders layer and coupling beam 12 step by step, channel floor steel platform is made to form cavity, part second diagonal web member assembly 922 and upper chord assembly 931 hang in described Core Walls Structure by substep, girders layer is fixedly connected to form by lifting the described second diagonal web member assembly 922 that puts in place and upper chord assembly 931 and the first diagonal web member assembly 921, equally, after each step dismounting installation terminates, all the steel deck-plate 14 be removed in this step and coupling beam 12 to be recovered to install.
Similar with described step b1, in order to improve efficiency of construction, also can remove the part steel deck-plate 14 on two or more steel platform unit 11 and coupling beam 12 simultaneously, but in order to ensure stress balance, require that the steel platform unit simultaneously carrying out removing operation is symmetric with the center of Core Walls Structure, what show in Fig. 9 is the embodiment of simultaneously removing two the steel platform unit be symmetric with the center of Core Walls Structure, repeat above-mentioned steps, progressively by the lifting of all diagonal web member assemblies substep, and all diagonal web member assemblies are connected to form truss diagonal web member 92.
Equally, the order of substep dismounting steel platform unit can sort flexibly according to the actual needs of site operation.Preferably, in order to improve efficiency of construction, dismounting operation can be carried out to two or more steel platform unit simultaneously, but in order to stress equalization consideration, require that the two or more steel platform unit simultaneously carrying out removing operation are symmetric with the center of Core Walls Structure.
The above sets up the explanation that large-sized diagonal web member 92 carries out for example, in the occasion that girders layer size is less, in stepb, only needs once to promote, namely can complete the erection of diagonal web member 92.In addition, according to the real size of girders layer, synchronously can also complete the erection of diagonal web member 92 and upper chord 93, lower chord 91, diagonal web member 92 and upper chord 93 are connected rear final formation girders layer 9; Also can complete the lifting of diagonal web member 92 and upper chord 93 step by step, then lower chord 91, diagonal web member 92 and upper chord 93 are connected rear final formation girders layer 9.
So far, complete the erection to girders layer 9, after girders layer 9 has set up, for steel column drum rack alternating bracing hydraulic climb integral steel platform 100 subsequent construction for, the construction process of Engage of standard floor height, as long as carry out climbing operation according to the construction process of standard floor height, the operation of climbing for standard floor height belongs to prior art, does not repeat them here.
In like manner, in order to easy construction, preferably, require that the distance that the second predetermined altitude in step c is higher than girders layer 9 absolute altitude is 1400mm ~ 1800mm, the distance that the 3rd predetermined altitude in like manner in steps d is higher than girders layer 9 absolute altitude is 1400mm ~ 1800mm.It is to be noted, climb altitude in step a neutralization procedure c, should determine flexibly according to the stroke of the actual height of girders layer and the oil cylinder that climbs, such as, the steel column drum rack alternating bracing hydraulic integral steel platform that climbs just can be made can to rise to the first predetermined altitude or the second predetermined altitude by once to climb, also even repeatedly can be climbed by twice just to reach the first predetermined altitude or the second predetermined altitude.
In sum, in construction method of the present invention, substep removes the coupling beam on steel plateform system, integral steel platform is made to occur cavity, and by cavity, the assembly of composition girders layer is hung in Core Walls Structure inside respectively, and in the totally enclosed operating space of steel platform template system composition, the assembly of girders layer is assembled formation girders layer.Steel platform template system is relied on successively lifting to be installed along girders layer vertical section, avoid the fractionation combination operation to steel platform template system in high-altitude, whole work progress all carries out operation in totally enclosed space, ensure construction safety to greatest extent, construction method is easy simultaneously, effectively can shorten the girders layer construction period, effectively reduce construction cost.
Foregoing description is only the description to present pre-ferred embodiments, any restriction not to the scope of the invention, and any change that the those of ordinary skill in field of the present invention does according to above-mentioned disclosure, modification, all belong to the protection domain of claims.
