Problems solved by technology

Second, the connection form of this node is limited by the construction method
In the construction process, in order to extend the support rod steel pipe connected to the main rod steel pipe, it is necessary to reserve a hole on the main rod composite material pipe, and it is also required that the support rod steel pipe can only be opened in the range of the main rod composite material pipe The movable range of the main rod steel tube is also limited by the space inside the main rod composite material tube, so that the position of the support rod in the node cannot be set arbitrarily, otherwise it will not be able to be constructed; When the axes of the members are not coplanar) or the plane nodes with multiple members (the axes of the members are in the same plane) and other complex structural nodes, the construction process will be very difficult or even impossible.

Abstract

The invention relates to a double-steel-pipe concrete joint of an externally-wrapped composite winding pipe, and belongs to the technical field of building structures. The double-steel-pipe concrete joint comprises a main part and at least one auxiliary part, the structure of the main part is the same as that of the auxiliary part, and each of the main part and the auxiliary part comprises a composite winding pipe layer, an outer steel pipe layer, a concrete layer and an inner steel pipe layer which are sequentially arranged from outside to inside; the concrete layer is arranged between the inner steel pipe layer and the outer steel pipe layer in a pouring mode; a plurality of connecting parts are arranged between the outer steel pipe layer and the inner steel pipe layer, and the inner steel pipe layer and the outer steel pipe layer are fixedly connected through the connecting parts to form a double-steel-pipe section; and the double-steel-pipe section of the auxiliary part is fixedly connected with the outer side wall of the outer steel pipe of the double-steel-pipe section of the main part. The invention further relates to a preparation method of the double-steel-pipe concrete joint of the externally-wrapped composite winding pipe. The double-steel-pipe concrete joint of the externally-wrapped composite winding pipe is convenient to splice, simple in construction process and easy to process and manufacture.

Description

technical field [0001] The invention relates to a building structure, in particular to a double-steel tube concrete joint with an outsourcing composite material winding pipe, and also relates to a preparation method for an outsourcing composite material winding pipe double-steel tube concrete joint. Background technique [0002] The composite material-concrete-steel double-wall hollow tube component is a composite component proposed by Professor Teng Jinguang. It is composed of an external composite material winding tube, an internal steel tube and sandwich concrete between the two. It has good corrosion resistance and earthquake resistance. Strong advantage. The composite pipes and steel pipes in the composite member are not only used as the stress-bearing parts of the member, but also can be used as a formwork for pouring interlayer concrete, which realizes form-free construction, simplifies the construction process, and saves construction costs. [0003] However, how to ...
