Description
Technical Field
The utility model belongs to the technical field of the wallboard nodal connection is filled to the assembled, particularly, relate to a connection structure for assembled joins externally to fill wallboard.
Background
In view of the current development of the node connection technology of the prefabricated building, the main node connection modes are divided into a dry connection mode and a wet connection mode in terms of connection types. The wet connection mode of the nodes is that in the construction process, the integral connection of the structure is realized by pouring node concrete after the reinforcing steel bars are connected with each other, the wet connection is also called as cast-in-place connection, and the construction mode through the wet connection is not suitable for an assembled structure; in the construction technology of the dry connection node, firstly, components of reinforced concrete are prefabricated in a factory, parts such as steel plates for connection are embedded in the positions, needing to be connected, of the reinforced concrete according to a design drawing, and mechanical steel structure connection is carried out through bolts or special components made of steel in the process of node connection. Compared with wet connection, dry connection has poor integrity, and the problems of poor recovery and the like caused by ductility damage and overlarge deformation can occur during earthquake, so that serious damage can be easily caused; but the dry connection construction mode is convenient and efficient, meets the requirements of the current assembly integral type building, and needs to be further developed and improved.
Currently, there are three types of commonly used dry-type connection nodes, namely rigid connection nodes, flexible connection nodes and semi-rigid connection nodes.
The rigid connection refers to that the external wall panel and the main structure are connected into a whole in the form of bolts, welding or grouting and the like, and the external wall panel and the main structure are stressed together to generate corresponding deformation. The rigid node has wide application in practical engineering, mature technology and a set of complete specifications; concrete is not needed to be cast in situ, and the construction period is saved. But the rigid connection has obvious defects, the installation operation is more complicated, and a large internal force can be generated under the action of rare earthquakes, so that the wallboard is damaged and falls off, and serious earthquake damage is caused.
In the flexible connection node, the limiting hole is a long round hole, and the bolt can move in the hole, namely the external wall-hanging plate and the main structure can have relative displacement. Therefore, under the action of external load, larger internal force can not be generated to cause node damage, and the generation of wall body cracks or the falling-off condition of the wall board can be reduced; meanwhile, the installation difficulty of the long round hole and the plate structure is low, and the construction is convenient. The disadvantage of flexible connections is that the strength and rigidity of the outer wall panel is not fully utilized in earthquake resistance.
The semi-rigid connection node has good rigidity and ductility and also has certain shock resistance. Because the research of the semi-rigid node is still in the starting stage at present, a matched enclosure system is lacked to adapt to the semi-rigid node, and the wallboard cannot meet the deformation requirement under the earthquake action, so that the phenomenon that the wallboard cracks and even falls off in an early stage is caused.
The application number is CN202021963768.6 discloses an assembled wallboard mounting structure in the patent application, including vertical keel, wallboard and connector strip, be provided with many parallel arrangement's vertical keel in the wall basic unit, be provided with the multiunit jack of arranging along self length direction on the vertical keel, a set of jack includes two jacks of parallel arrangement, the wallboard both sides are provided with the connector strip of symmetrical arrangement, be provided with the buckle of the corresponding jack in position on the connector strip, the buckle joint is on the mount pad on the connector strip, and the tip of buckle is pegged graft in the jack, the mount pad includes L shape lateral wall and panel, the mounting panel joint of buckle is in the accommodation space that L shape lateral wall and panel formed, be provided with yielding separation blade on the L shape lateral wall, the separation blade supports the below at the buckle. In this structure, the installation effectiveness of wallboard is very low, and the baffle is the sheet metal of easy bending moreover, and its thermal insulation performance is lower, and wallboard stability is relatively poor, and has the seepage problem.
Application number is CN2021121587880.9 discloses an assembled wallboard connection structure in the patent application, including wall body and connecting plate, the connecting plate is located one side of wall body, be equipped with the built-in fitting in the wall body, the built-in fitting below is equipped with the thread bush, thread bush fixed mounting is in the wall body, be connected with fixed part between wall body and the connecting plate upper end, still include: be located the adapting unit between wall body and the connecting plate, adapting unit includes the mounting panel, mounting panel one side fixed mounting has the carriage release lever, carriage release lever one side is equipped with the connecting block, the mounting groove has been seted up on the connecting block one end lateral wall, the spout has all been seted up on the lower extreme inner wall on the mounting groove, the mounting panel was kept away from to the carriage release lever one end inserts in the mounting groove, fixed mounting has the slider on the carriage release lever outer wall. The structure can effectively solve the problem of uneven installation of the wallboard caused by uneven wall surface, improves the installation quality of the wallboard and has the characteristic of stable structure; however, under the action of earthquake, the wallboard can not meet the deformation requirement and is damaged.
It can be seen from the above that, the problem that wallboard is easy to be destroyed under the action of earthquake due to poor stability and insufficient deformability commonly exists in the existing semi-rigid connection node connection, and the existing semi-rigid connection node connection is poor in seepage prevention and heat preservation and heat insulation capacity. Therefore, a semi-rigid connection node connection structure which can improve the anti-seismic performance and has good sealing performance is urgently needed.
