Description

Technical Field

[0001] The utility model relates to the technical field of building structures, in particular to a node structure for a leap-storey truss steel diagonal brace and a steel concrete beam column. Background Art

[0002] In actual engineering construction projects, architects often need to cantilever a certain floor by about 10 meters in order to achieve the desired building facade effect. The functional space in the cantilevered area has a wide field of vision, and the beam section of the cantilevered floor is expected to be consistent with the beam height of the non-cantilevered area. For cantilevered structures, the structural design scheme can adopt the direct cantilevering of beams to bear the load of this floor. This scheme will cause the beam section to be too large, destroying the facade unity of the same floor.

[0003] Generally, a more feasible solution is to use a leap-floor truss with overall spatial stress. Cantilever leap-floor trusses generally use steel structures. Steel beams and steel diagonal braces are easier to connect, and hoisting and installation are also simple. However, the main body is generally a concrete structure. The connection between the cantilever steel structure and the main concrete structure is complex and costly. When the cantilever leap-floor truss uses a concrete structure, its construction formwork and bracket erection requirements are high, construction is difficult, and the components are relatively heavy, which loses the effect of the light cantilever of the building. Therefore, in order to combine the advantages of steel structure and concrete structure, the upper and lower chords of the cantilever truss can be made of steel concrete, and the support can be made of steel structure, but its node structure needs to be specially designed.

[0045] Example 3

[0046] Based on the content of Example 2, in a specific embodiment, according to Figure 1-Figure 7 As shown, the steel-concrete column 2 includes a second steel 21, a second stiffening plate 22, a column longitudinal reinforcement 23, a second sleeve 24, and a second concrete 25. The second steel 21 is provided with the second stiffening plate 22 at the position aligned with the flange of the steel-concrete beam 1 and the position aligned with the cross-section flange of the steel diagonal brace extension section 3, and the second stiffening plate 22 is vertically arranged to the second steel 21 to enhance rigidity and ensure local stability; the column longitudinal reinforcement 23 is arranged parallel to the outer periphery of the second steel 21, and the second sleeve 24 is welded on the column longitudinal reinforcement 23 at the intersection with the steel-concrete beam 1 and the steel diagonal brace extension section 3; the second steel 21, the second stiffening plate 22, and the column longitudinal reinforcement 23 constitute a space for pouring the second concrete 25.

[0047] In this embodiment, the number of column longitudinal reinforcements 23 is determined according to actual conditions. The purpose is to select the actual number for use under the premise of low cost, strong structural stability and simple operation. The number is greater than 2 and is evenly arranged along the circumference of the second steel section 21 to ensure uniform force.

[0048] In order to further improve the stability of the structure, Figure 3-Figure 7 As shown, the steel-concrete column 2 also includes a plurality of column stirrups 26 arranged at intervals along the height direction of the column longitudinal reinforcement 23, and the plurality of column stirrups 26 are welded to the column longitudinal reinforcement 23 and the second steel section 21; the column stirrups 26 adopt open hoops to wrap the second steel section 21, the second stiffening plate 22, and the column longitudinal reinforcement 23; the column stirrups 26 are welded at the contact points with the second steel section 21, the second stiffening plate 22, and the column longitudinal reinforcement 23 to improve the stability of the extended section of the steel-concrete column 2. Before the steel-concrete column 2 is placed on site, it can be welded together with the steel-concrete beam 1 (before pouring concrete) and the steel diagonal brace extension section 3, and then the welded structure is placed on site, so that the steel-concrete beam 1 is welded to the steel member 5, and the steel diagonal brace extension section 3 is welded to the box-type steel diagonal brace member 4, and then the formwork of the beam and column is supported as needed, and the first concrete 15 and the second concrete 25 are poured, so that the construction load is borne by the first steel 11 and the second steel 21, while the steel diagonal brace extension section 3 is subjected to less force and has lower requirements.

[0051] The node where the first steel section 11 in the steel concrete beam 1 is connected to the second steel section 21 in the steel concrete column 2 is called a beam-column steel connection node; in the utility model, after the steel concrete beam 1 is arranged at this end of the steel concrete column 2, the steel concrete beam 1 is connected to the steel section 5 on site to achieve factory welding (referring to factory welding before pouring the first concrete 15 and the second concrete 25), convenient on-site installation, reduce costs and improve work efficiency.

[0052] In a more specific embodiment, the node where the beam transverse reinforcement 13 in the steel-concrete beam 1 and the column longitudinal reinforcement 23 in the steel-concrete column 2 are to be connected is called a beam-column reinforcement connection node. Since the steel sections (which may be the first steel sections 11 and the second steel sections 21) at the node position block the penetration of the steel bars (which may be the beam transverse reinforcement 13 and the column longitudinal reinforcement 23) and cannot transmit force, the first sleeve 14 and the second sleeve 24 are designed in the utility model (see the above content for the specific structural position) to facilitate the connection between the steel bars (in the utility model, the beam transverse reinforcement 13 and the column longitudinal reinforcement 23) and the steel sections (in the utility model, the beam stirrups 16 and the column stirrups 26).
