Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.

[0033] In addition, if there are descriptions involving "first", "second" and ...

Abstract

The invention discloses a prefabricated multi-tube confined concrete double-wall hollow column. The prefabricated multi-tube confined concrete double-wall hollow column comprises an inner steel tube and a FRP outer tube arranged on the periphery of the steel inner tube, wherein a plurality of circumferentially-arranged prefabricated parts are arranged between the inner steel tube and the FRP outertube, inner circumference faces of the prefabricated parts are connected with the inner steel tube, outer circumference faces of the prefabricated parts are connected with the FRP outer tube, and theside faces of the two adjacent prefabricated parts are fixedly connected; a plurality of FRP inner tube bodies are arranged inside the prefabricated parts in the length direction and arranged in mortar layers. The invention also discloses a production device for producing the prefabricated parts and a production technology for the prefabricated multi-tube confined concrete double-wall hollow column. Compared with the prior art, the technical scheme has the advantages of being simple in structure, convenient and fast in production and installation and the like, the production quality of the prefabricated multi-tube confined concrete double-wall hollow column can be improved, production steps are simplified, and production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a prefabricated assembly type multi-pipe restrained concrete double-wall hollow column, a production device and a production process. Background technique [0002] Fiber reinforced polymer (Fiber Reinforced Polymer, FRP) is widely used in the field of engineering structure reinforcement technology because of its superior properties such as light weight and high strength, and its application to new structures has become a focus of attention of researchers and engineers in recent years. [0003] Due to the multi-tube confined concrete double-wall hollow column can give full play to the properties of FRP, steel pipe, concrete and mortar, and can well improve the compressive bearing capacity of the double-wall hollow column. However, in the production process of multi-tube confined concrete double-walled hollow columns, there are problems such as inaccurate positioning of...
