Embodiment 1

[0309] Embodiment 1.——I type section ( Figure 5 with Image 6 )

[0310] Steel pipe cement mortar composite structure, at a certain stage in the production process such as Figure 5 with Image 6 shown. Part A is made up of steel pipe 11, lower sealing plate 12 and upper sealing plate 13. A threaded circular hole 121 is provided at the center of the lower blocking plate 12 , and a threaded circular hole is also provided at the center of the upper blocking plate 13 , and a construction pipe 51 is connected to the hole. After the construction is completed, the construction pipe 51 will be unloaded or sawn off.

[0311] The steel pipe 11 in part A is made of Q345 steel with a yield strength of 345MPa. The steel pipe 11 is a seamless steel pipe with an outer diameter of 245 mm and a wall thickness of 12 mm. The fluid pressure in the cavity that can be tolerated at both ends of part A is greater than that of the side wall.

[0312] An isolating device 3 is installed in the c...

Embodiment 2

[0346] Embodiment 2.——II type section ( Figure 7 , Figure 8 )

[0347] Nearly completed CFST composite structures such as Figure 7 with Figure 8 shown. Part A of this structure is made up of steel pipe 11 , lower sealing plate 12 and upper sealing plate 13 . There is a feed circular hole 131 at the eccentric position of the upper blocking plate 13, which is used to inject B1 material; at the center of the upper blocking plate, a piston hole is arranged, and a pressurizing piston 6 is inserted in the hole, and the surface of the pressurizing piston Smooth, with a sealing ring set between the piston and the hole wall. There is an isolation device 3 inside the steel pipe. This device is an iron pipe with round holes distributed on the surface. The diameter of the round holes is 5-7mm. The outside of the iron pipe is wrapped with a metal mesh. The mesh is square and the eye width can be between 0.5-2mm. choose between. The iron pipe used as the isolation device is fixed...

Embodiment 3

[0352] Embodiment 3.——II type section ( Figure 9 , Figure 10 )

[0353] Concrete-filled steel tube composite structures such as Figure 9 with Figure 10As shown, part A is composed of a steel pipe 11 , a lower sealing plate 12 and an upper sealing plate 13 . The cavity of part A is provided with an isolating device, which is made up of corrugated iron plates 31 and 32, and the corrugated plates are fixed on the inner wall of the steel pipe. The area 22 surrounded by the corrugated plate is filled with material B2, the areas 211 and 212 between the steel pipe and the corrugated plate are filled with material B1, and all areas in the inner wall of part A that are in contact with material B1 are coated with retarding and antifriction materials.

[0354] The maximum value that part A can withstand the fluid pressure in the cavity is 55MPa, and after B1 and B2 materials are filled into the cavity, a pressure of 50MPa is applied to it.

[0355] B1 material is reactive powder...

Abstract

The invention relates to a composite structure with a high bearing capacity. The composite structure with the high bearing capacity comprises a part A and a part B. The part A is provided with a cavity, and the part B is a solidifiable material filled in the cavity and is under the pressure in the solidification process. The part B comprises a part B1 and a part B2, a material B1 is a cement-basedmaterial, a material B2 is a solidifiable material, and the material B2 has relatively high flowability compared with the material B1. A built-in or / and external volume compensation device is / are arranged. When the material(s) B1 and / or B2 are / is contracted and the material B2 has flowability, the built-in volume compensation device is expanded, or the external volume compensation device squeezesthe flowing and semi-flowing solidifiable material or solid material into a material B2 area in the cavity. The volume compensation device fills up the contracted volume, the pressure of the materialB2 in the cavity is maintained, and the pressure of the material B1 is further maintained. Optimally, the flowing time of the material B2 is larger than the time for the material B1 to arrive at a contraction turning point, and the pressure maintaining time at least exceeds the time for the contraction turning point of the material B1 to appear.

Description

technical field [0001] The invention relates to the fields of buildings and bridges, in particular to a composite structure and a manufacturing method thereof. Background technique [0002] The concrete in the steel pipe concrete composite structure will shrink, which will cause separation between the concrete and the inner wall of the steel pipe, affecting the cooperative work between the two, and then affecting the mechanical properties of the composite structure. [0003] In the existing literature, there are two categories of methods to solve this problem. The first category is to change the shrinkage characteristics of the concrete material to reduce the shrinkage as much as possible, or to allow the material to expand. This type of method has nothing to do with the present invention, and will not be described in detail. [0004] The second type of method is to apply pressure to the concrete after it has been filled into the steel pipe. There are two methods for apply...
