Further, the purpose of this utility model is to provide a kind of concrete filled steel tube structural member of putting more energy into, and this structural member can be avoided forming the concrete pumping space, improves the encased structures stress performance, improves the safety and the durability of structure.
For achieving the above object, the utility model provides a kind of concrete filled steel tube stiffening element, comprises an outside steel pipe, is connected with the steel plate of putting more energy on described steel pipe inwall, also is welded with the reinforcing bar of putting more energy on the described steel plate of putting more energy into; It is characterized in that, on described steel pipe inwall, also be connected with a plurality of expansions head screw of putting more energy into.
Preferably, the described steel plate of putting more energy into is welded on the described steel pipe inwall on described steel pipe cross sections direction.
Preferably, the described steel plate of putting more energy into is being welded on the described steel pipe inwall on the described steel pipe axis direction.
Preferably, the described steel plate of putting more energy into is provided with perforate.
Preferably, the described expansion head screw of putting more energy into is to be welded on symmetrically on the described steel pipe inwall about described steel pipe axis.
Preferably, the described reinforcing bar of putting more energy into is a groined type.
Preferably, the described reinforcing bar of putting more energy into is a rhombus.
The utility model is on the existing mode basis of putting more energy into, shortcoming at these modes of putting more energy into, for improving safety and the durability of structures of encased structures in work progress and in the use, on the steel pipe inwall, set up and expand the head screw of putting more energy into, thereby prevent the possibility of outside steel pipe squib effectively.In addition, the utility model also adopts the steel plate of putting more energy into the steel shaft line parallel, simultaneously adopt well word or the rhombus reinforcing bar of putting more energy into to connect between the steel plate putting more energy into, reduced the resistance in the core concrete pumping process, guarantee that the concrete pumping safety in work progress is smooth, thereby guarantee concrete density.

The specific embodiment
Below in conjunction with accompanying drawing put more energy into structure, characteristics and the effect of structural member of concrete filled steel tube of the present utility model elaborated.
As Fig. 5 A and 5B and shown in Figure 6, the concrete filled steel tube of the present utility model structural member embodiment one that puts more energy into comprises an outside steel pipe 1, be welded with the steel plate 2 of putting more energy at this steel pipe inwall on the steel pipe cross-sectional direction, the steel plate 2 of putting more energy into is general wide 100 millimeters and be welded on the whole girth of steel pipe inwall.Certainly, this steel plate of putting more energy into also can be shown in Fig. 4 A and 4B like that, which is provided with a plurality of perforates so that concrete pumping by avoiding near the steel plate of putting more energy into, forming the space.Be welded with the reinforcing bar 3 of putting more energy on the steel plate 2 of putting more energy into, this reinforcing bar of putting more energy into can be a groined type as shown in the figure, can be rhombus like that shown in Fig. 2 A and 2B also.The diameter of reinforcing bar of putting more energy into is generally 18 millimeters, and adopts double welding, weld length 5d=90 millimeter with the steel plate of putting more energy into.Further, in the utility model, also be welded with on the steel pipe inwall and expand the head screw 4 of putting more energy into, it is roughly the same or bigger with the steel plate width of putting more energy into that this expands the head general length of screw of putting more energy into, and diameter is about 20 millimeters.Expand the head screw 4 of putting more energy into and be distributed in symmetrically on the steel pipe inwall, and adopt pressure submerged arc welding mode to weld thereon.Put more energy into steel plate 2 and expand head put more energy into stiffening element such as screw can be on the steel pipe axis direction by 250 millimeters pitch arrangement.In the utility model, on outside steel pipe, increase the expansion head screw 4 of putting more energy into of weldering one determining deviation, improve the effect that is connected between steel pipe and the concrete, disperse because the structural stress that gradient of temperature, concrete shrinkage and creep etc. cause.Through adopting the labor of large-scale finite element procedure ANSYS, under equal conditions, adopt tradition to put more energy in the mode preferably under the situation of form three, four, the caused core concrete tensile stress of variations in temperature maximum value still reaches more than the 4Mpa; After adopting the mode of putting more energy into of the present utility model, this tensile stress is effectively reduced, and it is original about 30% that maximum value is reduced to, and this value is reduced within the tensile stress value that general core concrete allows.Because this tensile stress value is very important to durability of structures, therefore reduces this numerical value and just improved durability of structures greatly.
Fig. 7 A, 7B and shown in Figure 8 for another example, second embodiment of the utility model and first embodiment difference are, the steel plate 2 of putting more energy into is that the axial direction that is parallel to steel pipe 1 is welded on the steel pipe inwall, like this, can make concrete not be subjected to any stopping in the pumping process.In this embodiment, expanding the head screw 4 of putting more energy into is still along the steel pipe cross-sectional direction and distributes.In this embodiment, vertically the mode of putting more energy into of steel plate and well word reinforcing bar has effectively been offset concrete filled steel tube core concrete in work progress the radial stresses that outside steel pipe acted on has been guaranteed that work progress is safe and reliable; Adopt to expand the head screw of putting more energy on the other hand simultaneously and put more energy into and strengthen the effective connection of outside steel pipe and core concrete, disperseed concrete filled steel tube in the operation process owing to steel plate and the caused stress of core concrete relative deformation, make structure reliable durable more.The combination of two kinds of modes of putting more energy into, good solution encased structures the construction with the operation process in a series of problems.
