Problems solved by technology

[0006] In view of the fact that when the existing PVC-FRP pipe concrete column is connected with the shear wall, the method of opening holes on the PVC pipe is generally adopted, which is very easy to cause stress concentration and damage the PVC pipe. A PVC-FRP pipe of the present invention The connection structure between the concrete column and the concrete shear wall and the installation method of the connection structure strengthen the connection between the concrete column and the concrete shear wall without opening holes, and at the same time simplify the PVC- The construction technology of connecting FRP tube concrete column and concrete shear wall to speed up the construction progress

Embodiment 1

[0043] combine Figure 1-Figure 3 , a connection structure between a PVC-FRP pipe reinforced concrete column and a reinforced concrete shear wall in this embodiment, comprising a concrete column 2 and a shear wall 4 connected around the concrete column 2; the outer periphery of the concrete column 2 is wrapped more A rigid collar structure 3 constrains and strengthens the concrete column 2 . The plurality of collar structures 3 are arranged at intervals on the outer edge of the concrete column 2 and are closely attached to the concrete column 2 . In this embodiment, six collar structures 3 are provided in total. Both the upper and lower ends of the concrete column 2 are embedded with core steel pipes 1 , and one end of each core steel pipe 1 protrudes from the concrete column 2 .

[0044] combine Figure 5-Figure 7, the collar structure 3 of this embodiment includes a lower collar 31 and an upper collar 34, the two are fixedly connected by threads to form a collar structure...

Embodiment 2

[0059] The structure of this embodiment is basically the same as that of the embodiment, except that the plurality of ring structures 3 are fixedly connected to each other to form a whole, which is set on the outer edge of the concrete column 2 and is closely connected to the concrete column 2. fit. Meanwhile, specifically in this embodiment, the FRP type of the PVC-FRP pipe 21 is GFRP; the cross section of the prefabricated concrete column 2 is circular. The shear wall 4 is "L-shaped". The poured concrete 22 is high-strength concrete. The lower collar 31, the upper collar 34, the core steel pipe 1 and the connecting plate 6 are Q3455 steel. The distance between horizontally distributed ribs 5 is 150mm, and its diameter is less than or equal to the inner diameter of the hollow part of the hollow bolt. The cross section of the core steel pipe 1 is circular; the connecting plate 6 and the core steel pipe 1 are connected by bolts.

Abstract

The invention discloses a connecting structure of a PVC-FRP pipe concrete column and a concrete shear wall and an installation method of the connecting structure, and belongs to the technical field of building structure engineering. The connecting structure comprises a concrete column and shear walls connected to the periphery of the concrete column. The periphery of the concrete column is wrapped with a plurality of rigid lantern ring structures, and the lantern ring structures restrain and reinforce the concrete column. The method comprises the steps that the concrete columns and the shear walls are prefabricated firstly, and then field installation is conducted. The steel lantern rings and the core steel pipe are arranged on the basis of the PVC-FRP pipe concrete column, the PVC-FRP pipe plays a role in restraining the core concrete, the steel lantern rings with the lug plates and the pre-embedded core steel pipe can also provide restraining force for the core concrete, and the connecting structure can reliably connect the PVC-FRP pipe concrete column and the concrete shear wall and also can be used for connecting the core concrete and the concrete shear wall. And the bearing capacity and the anti-seismic property of the concrete column can be obviously improved. The method is simple, convenient and easy to popularize and use.

Description

technical field [0001] The patent of the invention relates to the technical field of building structure engineering, specifically a connection structure between a PVC-FRP pipe concrete column and a concrete shear wall and an installation method for the connection structure. Background technique [0002] Ordinary reinforced concrete makes full use of the respective advantages of steel bars and concrete. It is the most widely used material in today's structures. However, its shortcomings such as heavy weight, low bearing capacity, and complicated construction process limit its application in modern structures. Concrete-filled steel tube structures have the advantages of high bearing capacity and good seismic performance, but steel is prone to corrosion. In atmospheric or corrosive environments, concrete-filled steel tube columns have structural durability problems. In order to solve the above problems, PVC-FRP pipe concrete structure was proposed. Due to its high bearing capac...
