Embodiment 1

[0074] Such as Figure 1-Figure 4 As shown, a composite column 30 provided in this embodiment includes a round steel pipe 31 and 2-4 T-shaped steels 32; the round steel pipe 31 is poured with concrete 33, and a plurality of T-shaped steels 32 are spaced along the circumferential direction of the round steel pipe 31. Set, and the opposite end of the T-shaped steel 32 web and the flange is fixedly connected to the outer wall of the round steel pipe 31; the web 32b of the T-shaped steel 32 is located on the extension line of the diameter of the round steel pipe 31, and the flange 32a is provided with bolt holes.

[0075] Among them, several T-shaped steel 32 are arranged in various ways, such as figure 1 As shown, there are two T-shaped steels 32, and the webs of the two T-shaped steels 32 are located on the same diameter of the round steel pipe 31 to form a straight shape. Such as image 3 As shown, there are two T-shaped steels 32, and the webs of the two T-shaped steels 32 a...

Embodiment 2

[0079] This embodiment discloses a composite structure building, which includes beams, columns, shear walls and floors. Wherein the column is the combined column 30 in Example 1.

[0080] Such as Figure 5 As shown, the combined column 30 is embedded in the wall 4 as a column; the T-shaped steel flange on the outdoor side of the combined column 30 is the outer flange 3a, and the outer flange 3a is arranged parallel to the wall surface of the wall 4; The outer end face of the outer flange 3a is coated with an outer anti-corrosion layer (not shown); the outer side of the anti-corrosion layer of the outer flange is laid with several layers of glass wool boards 10, which are used to block the combined column 30 as a thermal bridge in the interior of the wall. Transfer heat flow between the outer sides.

[0081] While effectively eliminating the thermal bridge effect at the combined column 30 and improving the overall thermal insulation performance of the building, several layers...

Embodiment 3

[0096] This embodiment discloses a composite structure building, which is different from Embodiment 4 in that the beam in this embodiment is a partially clad steel-concrete composite member.

[0097] Such as Figure 6 and Figure 7 As shown, the partially clad steel-concrete composite member in this embodiment includes: first side steel plate 100, second side steel plate 200, stud 500, repair welding steel plate 400, stiffening steel plate 300, steel skeleton 600 and concrete 700.

[0098] The first side steel plate 100 and the second side steel plate 200 are arranged in parallel and spaced; It is fixedly connected with the second side steel plate 200.

[0099] The two stiffened steel plates 300 divide the partly clad steel-concrete composite member into the connection area A1 on the outside of the two stiffened steel plates 300, and the prefabricated area A2 between the two stiffened steel plates 300; the two stiffened steel plates 300 and the first side steel plate 100 an...

Abstract

The invention relates to the technical field of buildings, and particularly relates to combined columns and a combined structure building thereof. The combined columns comprise round steel tubes and aplurality of T-shaped steels, concrete is poured into the round steel tubes, and the plurality of T-shaped steels are arranged at intervals in the circumferential directions of the round steel tubes;the webs of the T-shaped steels are located on the diameter extension lines of the round steel tubes, and a bolt hole is formed in a flange; the round steel tube concrete is positioned near neutral axial and is mainly used for bearing axial force, the advantage of good axial compression mechanical property of the round steel tube concrete is fully exerted, the T-shaped steels are arranged away from the neutral axial, the force arm is increased, the flexural bearing capacity is greatly improved, and the flexural mechanical property is greatly improved. Meanwhile, the T-shaped steels are located on the outer side so as to facilitate connection, all-bolt connection of beam column joints and column and column vertical splicing joints is achieved, steel columns can be prevented from being exposed out of a wall body when connected, so that the purpose of hiding the columns in the wall body is achieved. In addition, the combined columns have the advantages of simple machining, automatic production and low production cost.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a composite column and a composite structure building thereof. Background technique [0002] Prefabricated building is the direction of transformation and upgrading of the construction industry, and it is also an emerging sunrise industry vigorously promoted by the country. Prefabricated steel structure residences are a new type of building that is being vigorously piloted by the state. However, there is still a lack of suitable structural systems for prefabricated steel structure residences, especially the form of vertical load-bearing components. The structural system is not applicable. Residential buildings have complex functions, high requirements for use (such as beams and columns not exposed), high requirements for safety, high requirements for energy saving, heat preservation, sound insulation and fire prevention, and difficult maintenance during the service period. At...
