Description
Technical Field
The utility model belongs to the technical field of the wallboard connection of assembled steel structure system, concretely relates to take assembled steel structure externally-hung wallboard connecting piece of bayonet socket.
Background
During structural design and field construction, the external wall panel is used as a main external maintenance component of the steel frame structure, plays an important role in separation and heat preservation, and is important to realize whether the rapid installation of the external wall panel is realized or not and whether the steel structure assembly is realized or not. Traditional wallboard connected mode has hanging some connection, self tapping bolted connection, and the comparatively complicated difficult assembly that realizes the wallboard connection of its connected mode, breaks through the wallboard structural layer easily when using self tapping bolted connection and leads to the appearance of hourglass water, the scheduling problem that leaks out, should strictly avoid in industrial building.
The wallboard connecting node is used as a key part for connecting the wallboard and a structural stress member in the steel frame structure peripheral protective system, and influences whether the whole structure can be assembled or not to a great extent. Therefore, in the research of the assembly structure, the research on the wall panel connecting node is important content, and has larger and more important significance than the research on the general structure.
The manufacturing cost of the wall body in the general project at the present stage can generally reach 15% -25% of the civil engineering, along with the development of economy and the functional requirements on buildings, the heat preservation, the heat insulation and the decoration of the wall body enable the manufacturing cost of the wall body to be higher, and in the assembled steel structure, the outer wall accounts for about 70% of the total manufacturing cost. The self weight of the assembled external wall panel is light, the connection nodes can be reliably connected with the main structure, and the semi-rigid connection nodes can also enable the external wall panel to keep coordinated deformation with the main structure within a certain range, so that the wall panel is protected, and serious secondary disasters caused by falling of the wall body under the earthquake action are avoided.
At present, the research on the external wall panel mainly focuses on two aspects, one is to research the wall panel, and the strength and the rigidity of the wall panel are improved by replacing wall materials, and functions such as heat preservation and decoration are added, or the structure of the wall panel is changed to improve the bearing capacity of the wall panel. The main structure is connected with the external wall board through a connecting node, and the connecting node is connected with the main structure through a bolt, a connecting key and the like. The external wall panels need to be assembled together, and a large number of transverse seams and vertical seams can not only cause the decoration problem, but also influence the transmission of force between the wall panels and influence the cooperative deformation of a structural system. And on the other hand the influence of the connection of the wall panels and their nodes on the main structure.
The main structure and the connecting node of the external wall panel are important parts for ensuring the use safety of a building, the reasonable design of the connecting node influences the cooperative work of the wall panel and the main structure, the external wall panel is more and more researched, the wall panel quality is reduced, the heat preservation, the heat insulation, the decoration and fitment integrated wall panel and other functions are more and more complete, but the existing connecting node of the external wall panel is not more researched, and the external wall panel is not suitable for falling and damaging inside and outside the surface of the wall panel due to the lack of proper connection under the effects of self weight, wind load and earthquake.
The traditional connecting node comprises a rigid connecting node and a flexible connecting node, wherein the rigid connecting node enables a main body structure and an external wall panel to deform together under the load action in a welding or pouring mode, and the like. The flexible connecting nodes can lead the external wall panel and the main structure to deform and coordinate to achieve the redistribution of the internal force of the system, and the flexible connecting nodes have the advantages that the wall panel can be protected from being damaged under large deformation, and the defects that the strength and the rigidity in the surface of the external wall panel cannot be completely and effectively utilized.
In conclusion, the connecting node of the external wall panel and the main structure is a research hotspot of the assembled building, students make a great deal of research 23428, the strength and the rigidity of the node have important influence on the shock resistance of the main structure, the damage between the external wall panel and the steel frame is mainly concentrated in the node area, and the deformation of the wall panel and the main structure can be coordinated to a certain extent by using the semi-rigid connecting node to adapt to the structural deformation. In the stress process, the wall board protects the wall board when the structural deformation is small, participates in rigidity contribution when the displacement change is large, and has great influence on the anti-seismic performance and the dynamic performance of a structural system consisting of the main body structure, the connecting nodes and the external wall boards.
Based on the above, a fabricated steel structure wallboard and wall beam connecting node with bayonets is provided. The joint can well solve the problem of quick connection of the steel beam and the external wall panel and has the outstanding advantages of rapidness, good quality and economy. And this kind of connected mode precision is high, with low costs, fast, has fully agreed with assembly type building's advantage, has realized the high-speed connection of girder steel and side fascia. The node has simple structure and convenient installation and disassembly, can realize the quick connection of the beam plate in the installation and construction, and has great significance for the maintenance in the later period.
