Embodiment 1

[0033] Such as Figure 1-7 As shown, the combined structural system of steel pipe concrete columns and cast-in-place beams of the present invention includes a steel pipe column 1, which is a hollow structure, and the steel pipe column 1 is provided with at least two first installation openings 10 communicating with its inner cavity, each with two second installation openings. One installation port 10 is arranged oppositely; in addition, at least two second installation ports 11 communicating with the inner cavity of the steel pipe column 1 are also opened, and each two second installation ports 11 are arranged oppositely, and the first installation port 10 and the second installation port 11 are on different planes. The steel pipe column 1 in this embodiment is a rectangular steel pipe column 1, that is, it can be understood that the rectangular steel pipe column 1 has a first side wall 12 and a second side wall 13 opposite to each other, and two first installation ports 10 O...

Embodiment 2

[0045] Such as Figure 8 As shown, the difference between the present embodiment and the first embodiment lies in the number of the first installation opening 10 and the second installation opening 11 are different.

[0046] In this embodiment, since the lengths of the first installation opening 10 and the second installation opening 11 need to be opened according to the height of the cast-in-place beam, when the height of the cast-in-place beam is high, two first installation openings 10 (a pair of first installation openings 10) are opened. One installation opening 10) and two second installation openings 11 (a pair of second installation openings 11) will weaken the overall rigidity of the steel pipe column 1. Therefore, four first installation openings 10 and two second installation openings 11 in this embodiment are opened respectively, that is, two pairs of first installation openings 10 and two pairs of second installation openings 11, on opposite first sides of the ste...

Abstract

The invention discloses a concrete filled steel tubular column and cast-in-place beam combined structure system which comprises a first sleeve piece, a second sleeve piece and a hollow steel tubular column, the steel tubular column is provided with at least two first mounting ports and at least two second mounting ports which are communicated with an inner cavity of the steel tubular column, every two first mounting ports are oppositely arranged, and every two second mounting ports are oppositely arranged. The first mounting port and the second mounting port are positioned on different planes; the first sleeve part can penetrate through the steel pipe column through the first mounting opening, and first holes communicating with an inner cavity of the first sleeve part are formed in the two opposite side walls of the first sleeve part; the second sleeve part can penetrate through the steel pipe column through the second mounting opening and is in mortise and tenon joint with the first sleeve part through the first hole, so that a mortise and tenon joint of the steel pipe concrete column and the cast-in-place beam is formed, and out-of-plane deformation of a wall plate of the steel pipe column after the steel pipe concrete column and the cast-in-place beam are connected and combined is avoided; therefore, the bearing capacity of the connecting joint of the concrete-filled steel tubular column and the cast-in-place beam is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a combined structural system of steel pipe concrete columns and cast-in-place beams. Background technique [0002] At present, there are various forms of building structures, and the corresponding forms of beam-column joints are also varied. Among them, the rectangular steel-filled concrete column has reasonable stress, good fire performance and economic indicators, so it is usually combined with beams to form a steel-concrete combination in buildings. structural system. However, in the existing steel-concrete composite structure system, the beam-column joints are difficult and inconvenient to construct due to their complex structural form and cumbersome structure. Therefore, it is urgent to improve the composite structure system of steel tube concrete columns and cast-in-place beams. Contents of the invention [0003] Aiming at the deficiencies of the prior art,...
