3rd, on the one hand the implantation of corrugated bushing realizes the positioning of bar connecting, on the other hand by filling in corrugated bushing Enter ungauged regions self-compacting high-strength concrete and improve adhesive strength.
This utility model is described in further detail below in conjunction with drawings and Examples;But a kind of dress of the present utility model Embodiment is not limited to splicing construction of the formula steel core concrete column with post.
Description of the drawings
Fig. 1 is overall structure diagram of the present utility model;
Fig. 2 is decomposition texture schematic diagram of the present utility model;
Fig. 3 is perspective structure schematic diagram of the present utility model;
Fig. 4 is the sectional view of steel core concrete column under this utility model.
Specific embodiment
Refer to shown in Fig. 1 to Fig. 4, the splicing construction of a kind of assembly concrete-filled steel tube post and post, including it is setting up and down Two steel core concrete columns.Some reinforcing bars 3 are embedded with upper steel core concrete column 1 and 3 part of reinforcing bar extends downwardly out steel pipe 1 bottom surface of concrete column;Some corrugated bushings 4 are embedded with lower steel core concrete column 2,4 one end open of corrugated bushing is exposed to down 2 top surface of steel core concrete column.Correspond by injection concrete grout in corrugated bushing 4 and by reinforcing bar 3 and corrugated bushing 4 slotting Connect, so that 1 bottom surface of upper steel core concrete column is docked with lower 2 top surface of steel core concrete column, while passing through welded still pipe docking site Realize the splicing of two steel core concrete columns.
The diameter parallel of reinforcing bar 3 and upper steel core concrete column 1 is arranged, the axis of corrugated bushing 4 and lower steel core concrete column 2 It is arranged in parallel, upper and lower steel core concrete column 1,2 is coaxial to be spliced, so as to form an entirety.
Internal diameter of the diameter of reinforcing bar less than corrugated bushing, specifically, 3~7 times for 3 diameter of reinforcing bar of 4 internal diameter of corrugated bushing, and It is and preferred reinforcing bar 3 is located at the middle part of corrugated bushing 4, to guarantee that 3 periphery concrete thickness of reinforcing bar is uniform, stable so as to improve which Property.By the setting of corrugated bushing, reinforcing bar is limited within corrugated bushing, and improves adhesive strength.
Further, corrugated bushing 4 is in border spread configuration along the cross section of lower steel core concrete column 2, and its spread geometry It is consistent with the shape of lower 2 cross section of steel core concrete column.For example, steel core concrete column is square column, then corrugated bushing 4 weeks Circle arrangement also forms square, so that it is guaranteed that uniform force in all directions.The setting of reinforcing bar and corrugated bushing with it is consistent.Additionally, The setting space of corrugated bushing should also meet the requirement of related specifications and construction and be played a role with the shear-carrying capacity for ensureing reinforcing bar.
Further, the concrete grout for pouring into corrugated bushing is ungauged regions self-compacting high-strength concrete, and strength grade is not low In the concrete grade of steel core concrete column.
The joining method of above-mentioned splicing construction, comprises the following steps:
1) upper steel core concrete column prefabricated component and lower steel core concrete column prefabricated component are provided, upper steel core concrete column is prefabricated Part includes steel core concrete column 1 and the reinforcing bar 3 being embedded in steel core concrete column in advance, lower steel core concrete column prefabricated component bag Include lower steel core concrete column 2 and the corrugated bushing 4 being embedded in lower steel core concrete column in advance;
2) under, steel core concrete column prefabricated component carries out concrete grouting to corrugated bushing 4 in job site fixation in place;
3) on, steel core concrete column prefabricated component is placed on lower steel core concrete column prefabricated component and will be reinforcing bar 3 one-to-one In insertion corrugated bushing 4, so that upper steel core concrete column bottom surface is docked with lower steel core concrete column top surface;
4) the steel pipe docking site for welding upper steel core concrete column 1 and lower steel core concrete column 2 makes overall.
Wherein, upper steel core concrete column prefabricated component and lower steel core concrete column prefabricated component can be completed in factory process, its Splicing step can be implemented in job site.The manufacture method of lower steel core concrete column prefabricated component is:According to design requirement, there is provided steel Pipe, by it is some corrugated bushings parallel with steel pipe axis be arranged in steel pipe among and corrugated bushing one end is concordant with steel pipe one end, Region injection concrete grout in steel pipe outside corrugated bushing forms steel core concrete column fixed corrugated bushing simultaneously.Upper steel pipe The manufacture method of concrete column prefabricated component is:According to design requirement, there is provided steel pipe, by some reinforcing bars parallel with steel pipe axis row Among being distributed in steel pipe and each reinforcing bar part is extended outside steel pipe, and the arrangement position of reinforcing bar is corresponding with corrugated bushing, to steel pipe Interior injection concrete grout forms steel core concrete column fixed reinforcing bar simultaneously.
Upper steel core concrete column prefabricated component and lower steel core concrete column prefabricated component can pass through streamline mass in factory Production.Illustrating by taking the splicing of two concrete filled steel tube prefabricated components as an example in the present embodiment, those skilled in the art understand, each steel pipe is mixed Solidifying earth pillar prefabricated component can arrange corrugated bushing, bottom setting reinforcing bar in top simultaneously, so as to realize that seriality multicolumn splices.
Further, upper and lower steel core concrete column can connect to form entirety by groove welding, and each seam stays V-butt, In seam welding after grafting, and the intensity of weld seam is not less than the intensity of steel pipe itself.
Above-described embodiment is only used for the spelling for further illustrating a kind of assembly concrete-filled steel tube post of the present utility model and post Binding structure, but this utility model is not limited to embodiment, it is every according to technical spirit of the present utility model to above example Any simple modification, equivalent variations and the modification made, each falls within the protection domain of technical solutions of the utility model.
