Also being embedded with prefabricated reinforcing steel bar cage 6 in described concrete 4, described prefabricated reinforcing steel bar cage 6 is non-penetrating to be connected between adjacent horizontal splitter plate 2.In other embodiments, prefabricated reinforcing steel bar cage 6 can also pass hole 9, along the through setting of cavity.
Described prefabricated reinforcing steel bar cage is by indulging muscle 6.1 and stirrup 6.2 forms.
Further, the transverse section of described prefabricated reinforcing steel bar cage 5 is rectangle, can also be circular in other embodiments or other polygon.
Embodiment three sees shown in Fig. 5-6, and unlike embodiment one, outside plate 1 and inner side steel plate enclose connection and form two cavitys 3, respectively one loculus and a big chamber.Concrete 4 it is filled with in described cavity.Each little intracavity is provided with through cylinder, the core reinforcing bar 2 separated with outside plate and inner side steel plate, in a big chamber, is provided with four core reinforcing bars 2.Described core reinforcing bar 2 is welding L-type steel.
Embodiment four sees shown in Fig. 7-8, and unlike embodiment two, described core reinforcing bar 2 is welding L-type steel, and the transverse section of described reinforcing steel bar cage 5 is circular.
The construction method of the multi-cavity steel tube concrete post of this embedded separate type reinforcing bar, construction procedure is as follows:
Step one, in factory, material piecemeal is cut into welding outside plate 1, inner side steel plate and horizontal splitter plate 5, if core reinforcing bar 2 is welding fabrication, then it is also required to be cut into by material piecemeal the steel plate of core reinforcing bar 2 simultaneously, if core reinforcing bar 2 is roll forming, then module installed by the reinforcing bar being processed into core reinforcing bar 2 along short transverse by different length specification；
Step 2, outside plate 1 in step one and inner side steel plate are processed into multi-cavity steel tube respectively by design transverse shape, fix horizontal splitter plate 5 in the inside of multi-cavity steel tube simultaneously, and in the middle part hole-opening 9 of horizontal splitter plate 5, multi-cavity steel tube is processed ultimately forming multi-cavity steel tube along short transverse by different length specification and installs module；If needing core reinforcing bar 2 is welding fabrication, then by the steel plate of the core reinforcing bar 2 in step one by designing transverse shape, ultimately forming reinforcing bar installation module along short transverse by the processing of different length specification；
Step 3, multi-cavity steel tube is installed module and reinforcing bar and installs after module is transported to job site, multi-cavity steel tube is installed module and reinforcing bar is installed module and lifted by crane installation respectively, and the multi-cavity steel tube that aligns installs module and the center of reinforcing bar installation module, multi-cavity steel tube is installed interim connection between module and reinforcing bar installation module fixing；
Step 4, installs module by multi-cavity steel tube and reinforcing bar is installed module upper and lower split respectively and is welded into entirety.
Step 5, casting concrete 4 in cavity 3, and carry out maintenance, make outside plate 1, inner side steel plate, core reinforcing bar 2 and concrete 4 connect and form overall primary structure member.
Further, in work progress, reinforcing bar is installed module and hangs in the cavity that multi-cavity steel tube installs module from the top of multi-cavity steel tube installation module, ensure that reinforcing bar is installed the construction height of module and installed the construction height of module less than multi-cavity steel tube simultaneously, or multi-cavity steel tube is installed the module top hanging sleeve from reinforcing bar installation module the outside of module is installed in reinforcing bar, ensure that multi-cavity steel tube installs the construction height construction height less than reinforcing bar standard knot of module simultaneously.
As steel floor of putting more energy into need to be arranged, then steel floor of also putting more energy in needing the factory in step one, and will put more energy in step 2 steel floor and outside plate and/or inner side Plate Welding, collectively constitute the multi-cavity steel tube in step 3 and module is installed.
Reinforcing steel bar cage 6 can also be added in concrete, further enhance the bearing capacity of concrete.Vertical muscle 6.1 and stirrup 6.2 are processed in factory prefabricated reinforcing steel bar cage by described step one module is installed, and reinforcing steel bar cage installation module hung in multi-cavity steel tube installation module after step 3, be enclosed within outside reinforcing bar installation module, then fixing in cavity, last and concrete 4 forms entirety.
For the bond stress of Concrete Structure, in described step one, by the surface weld stud in advance of outside plate 1, inner side steel plate, core reinforcing bar 2 or steel floor of putting more energy into.
