Description

Assembled steel structure external wall panel connector with bayonet

technical field

The utility model belongs to the technical field of wall panel connection of an assembled steel structure system, in particular to an assembled steel structure external wall panel connector with a bayonet.

Background technique

In structural design and on-site construction, external wall panels are the main external maintenance components of steel frame structures, which play an important role in separation and insulation. The most important. The traditional wall panel connection methods include hanging point connection and self-tapping bolt connection. The connection method is more complicated and difficult to realize the assembly of wall panel connection. When using self-tapping bolt connection, it is easy to break through the wall panel structural layer, resulting in water leakage, air leakage and other problems. appear and should be strictly avoided in industrial buildings.

As the key part of the connection between the wall panels and the structural members in the steel frame structure enclosure system, the wall panel connection nodes greatly affect whether the overall structure can be assembled. Therefore, in the study of prefabricated structures, the study of the connection nodes of wall panels is an important content, which has greater and more important significance than the study of general structures.

At this stage, the cost of walls in general projects can generally reach 15%-25% of civil engineering. With the development of the economy, the functional requirements for buildings, thermal insulation and decoration of walls make the cost of walls higher. In the fabricated steel structure, the exterior wall accounts for about 70% of the total cost. The prefabricated external wall panels are light in weight, and the connection nodes can ensure a reliable connection with the main structure. The semi-rigid connection nodes can also keep the external wall panels in a certain range and maintain coordinated deformation with the main structure, thereby protecting the wall panels and avoiding earthquakes Under the action, the wall body falls off and brings serious secondary disasters.

At present, the research on external wall panels mainly focuses on two aspects. One is to study the wall panels themselves, to improve the strength and rigidity of the wall panels by replacing the wall materials, and to increase the functions of thermal insulation and decoration, or to change the structure of the wall panels to improve the wall panels. carrying capacity etc. The main structure and the external wall panels are connected through connecting nodes, and the connecting nodes and the main structure are connected through bolts and connecting keys. External wall panels need to be assembled piece by piece. A large number of horizontal joints and vertical joints will not only cause decoration problems, but also affect the force transmission between wall panels and affect the coordinated deformation of the structural system. On the other hand, it is to study the influence of the connection of wall panels and their joints on the main structure.

The connection node between the main structure and the external wall panel is an important part to ensure the safety of the building. The rational design of the connection node affects the cooperation between the wall panel and the main structure. More and more research and development of the external wall panel reduce the quality of the wall panel, heat insulation , decoration and decoration integrated wall panels and other functions are becoming more and more complete, but there are not many studies on the connection nodes of external wall panels at present, and the lack of suitable connections will cause the inside and outside of the wall panels under the action of self-weight, wind load and earthquake. Shedding damage.

Traditional connection nodes are divided into rigid connection nodes and flexible connection nodes. Rigid connection nodes use welding or pouring to make the main structure and external wall panels deform together under load. The disadvantage of this connection method is that when the wall panels and the main body The deformation of the structure exceeds the strength and stiffness of the connecting nodes, and the damage of the nodes leads to safety accidents. The advantage is that the wall panels contribute greatly to the structural stiffness. The flexible connection node can coordinate the deformation of the external wall panels and the main structure, and achieve the redistribution of the internal force of the system. The advantage is that it can protect the wall panels from damage under large deformation. The disadvantage is that the strength and stiffness in the surface of the external wall panels cannot be fully and effectively used. .

To sum up, the connection nodes between the external wall panels and the main structure are the research hotspots of prefabricated buildings. Scholars have done a lot of research. The strength and stiffness of the nodes have an important impact on the seismic capacity of the main structure. External wall panels and The damage between the steel frames is mainly concentrated in the joint area, and the use of semi-rigid joints can coordinate the deformation of the wall panels and the main structure to a certain extent, and adapt to the structural deformation. During the stress process, the wall panel protects the wall panel when the structural deformation is small, and participates in the stiffness contribution when the displacement changes greatly, and has a great influence on the seismic performance and dynamic performance of the structural system composed of the main structure, connecting nodes and external wall panels.

Based on the above content, a connection node between the assembled steel structure wall panel and the wall beam with bayonet is proposed here. This kind of joint can well solve the problem of fast connection between steel beams and exterior wall panels, and has the outstanding advantage of "more, faster, better and more economical". Moreover, this connection method has high precision, low cost and fast speed, which fully meets the advantages of prefabricated buildings and realizes the rapid connection of steel beams and exterior wall panels. This kind of joint structure is simple, easy to install and disassemble, not only can realize the quick connection of the beam and slab in the installation and construction, but also has great significance for the later maintenance.
