Description

Technical Field

[0001] The utility model relates to the field of civil engineering, in particular to a steel structure connection node. Background Art

[0002] The connection node is the key part of the transmission of internal force between different components of the structure, and the node area is often subjected to complex forces. Therefore, reasonable structure, clear force transmission and convenient construction are the requirements for node design to meet the seismic design requirements of the overall node and even the overall structure. In the traditional chord-steel web welded node structure (such as chord column-steel web beam node, chord steel tube-steel web node), one or more internal partitions are often required to be set inside the chord to improve the force stability of the node area. In this way, the structural nodes are numerous and complex, which brings inconvenience to the construction work, and there is a certain construction difficulty in welding the internal partition inside the steel tube. Therefore, a chord-steel web connection node form with partial concrete filling is designed to reduce the number of internal partitions in the chord component, facilitate construction, and improve the quality of the structure.

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0023] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0024] In the description of the present utility model, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "installed / connected", "connected", etc. should be understood in a broad sense. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection. It can be a mechanical connection or an electrical connection. It can be a direct connection or an indirect connection through an intermediate medium. It can be the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0025] refer to Figure 1 The present embodiment provides a steel structure connection node partially filled with concrete, comprising: a chord 1, an inner partition 2, concrete 3, and a steel web 4; a concrete 3 pouring hole is reserved on the surface of the chord 1; the chord 1 is connected to the steel web 4; the inner partition 2 is composed of two pieces, which are welded to the inside of the chord 1 at intervals; and the concrete 3 is poured between the two inner partitions 2.

[0026] The concrete 3 is a lightweight high-strength concrete 3. A hole 5 is left on the chord 1 for pouring the concrete 3. The concrete 3 is poured after the chord 1 is connected to the steel web 4. This ensures that the concrete 3 is not damaged by the high temperature generated when the chord 1 is welded to the steel web 4. The chord 1 is connected to the steel web 4 by welding or bolts.

[0027] The chord bar 1 can be a round steel tube, a square steel tube or a rectangular steel tube bar. The steel web bar 4 can be an I-beam, a channel steel or a steel tube.

[0028] In this embodiment, the inner partition 2 is welded to the chord 1 , and the spacing of the inner partition 2 is not less than the connection range between the chord 1 and the steel web 4 , and the thickness of the inner partition 2 is less than the wall thickness of the chord 1 .

[0029] The above-mentioned steel structure connection node partially filled with concrete 3 does not need to set too many internal partitions 2 in the chord 1 of the node area, avoiding or reducing the welding workload of the internal partition 2, saving steel, simplifying construction, and further ensuring the quality of the project; the node area is filled with concrete 3 to form a local steel tube concrete 3 structure, which greatly improves the bearing capacity, stiffness and seismic performance of the node area, and also reduces the probability of stable damage in the node area. In addition, the range of the chord 1 concrete 3 node can be reasonably designed to control the weak position of the chord 1-steel web 4 connection node, effectively realizing the seismic design principle of "strong node and weak component", and further improving the seismic safety of the overall structure.

[0030] The above is only a preferred specific implementation of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
