Description

A connection structure for prefabricated external hanging filling wall panels

technical field

The utility model belongs to the technical field of joint connection of assembled filling wallboards, in particular relates to a connection structure for assembled externally hanging filling wallboards.

Background technique

Judging from the current development status of prefabricated building node connection technology, the main node connection methods are divided into dry and wet connection methods in terms of connection types. Among them, the node wet connection method, that is, in the process of construction, the steel bars are connected to each other and then the overall connection of the structure is realized by pouring node concrete. The wet connection is also called the cast-in-place connection. The method of construction through wet connection is not suitable for assembly In the structure; in the dry connection node construction technology, firstly, the reinforced concrete components are prefabricated in the factory, and at the same time, according to the design drawings, the reinforced concrete construction needs to be connected. During the process, the steel structure is mechanically connected by bolts or special parts made of steel. Compared with the wet connection, the integrity of the dry connection is poor. In the event of an earthquake, problems such as ductile failure and excessive deformation will cause poor restoring force, which will easily cause serious damage. However, the construction method of the dry connection is convenient and efficient, which is in line with the current prefabricated monolithic buildings. The requirements need to be further developed and improved.

There are three types of dry joints commonly used at present, rigid joints, flexible joints, and semi-rigid joints.

Rigid connection refers to the connection of the exterior wall panel and the main structure as a whole by means of bolts, welding or grouting, etc., and the joint stress produces corresponding deformation. The main connection forms include angle steel connection, embedded sleeve connection, steel card consolidation and hook bolt connections, etc. Rigid joints are widely used in actual engineering, with mature technology and a complete set of specifications; no need for cast-in-place concrete, saving construction time. However, the disadvantages of rigid connection are also obvious. The installation operation is relatively cumbersome, and a large internal force will be generated under the action of a rare earthquake, which will cause the wall panel to break and fall off, resulting in serious earthquake damage.

In the flexible connection node, the limit hole is an oblong hole, and the bolt can move in the hole, that is, there can be relative displacement between the external wall panel and the main structure. Therefore, under the action of external load, no large internal force will be generated to cause node damage, which can reduce the occurrence of wall cracks or wall panels falling off; at the same time, the oblong hole and plate structure are less difficult to install and easy to construct. But the shortcoming of the flexible connection is that the strength and stiffness of the external wall panels are not fully utilized in the earthquake resistance.

Semi-rigid connection nodes have good stiffness and ductility, and also have a certain seismic capacity. Since the current research on semi-rigid joints is still in its infancy, there is a lack of supporting enclosure systems to adapt to it. Under the action of earthquakes, wall panels cannot meet the deformation requirements, resulting in premature cracks or even falling off of wall panels.

The patent application with the application number CN202021963768.6 discloses a prefabricated wall panel installation structure, including vertical keels, wall panels and connecting clips. There are multiple vertical keels arranged in parallel on the base of the wall, and the vertical keels are provided with Multiple sets of jacks arranged along its own length direction, one set of jacks includes two jacks arranged in parallel, symmetrically arranged connecting clips are arranged on both sides of the wallboard, and buckles corresponding to the positions of the jacks are arranged on the connecting clips , the buckle is snapped on the mounting base on the connecting clip, and the end of the buckle is plugged into the socket, the mounting base includes an L-shaped side wall and a panel, and the mounting plate of the buckle is snapped on the L-shaped side wall In the accommodating space formed with the panel, the L-shaped side wall is provided with a deformable blocking piece, and the blocking piece is against the bottom of the buckle. In this structure, the installation efficiency of the wall panels is very low, and the baffles are easy-bending metal sheets, which have low thermal insulation performance, poor stability of the wall panels, and leakage problems.

The patent application with the application number CN2021121587880.9 discloses a prefabricated wall panel connection structure, including a wall and a connecting plate, the connecting plate is located on one side of the wall, and there are embedded parts in the wall. There is a threaded sleeve under the embedded part, and the threaded sleeve is fixedly installed in the wall, and a fixed part is connected between the wall and the upper end of the connecting plate, and also includes: a connection between the wall and the connecting plate Components, the connecting part includes a mounting plate, a moving rod is fixedly installed on one side of the mounting plate, a connecting block is arranged on one side of the moving rod, a mounting groove is opened on the side wall of one end of the connecting block, and the mounting groove Slide grooves are provided on the inner walls of the upper and lower ends, and the end of the moving rod away from the mounting plate is inserted into the mounting groove, and a slider is fixedly installed on the outer wall of the moving rod. Although this structure can effectively solve the problem of uneven installation of wall panels caused by uneven walls, improve the installation quality of wall panels, and has the characteristics of structural stability; however, under the action of earthquakes, wall panels cannot meet the deformation requirements and are damaged.

It can be seen from the above that the existing semi-rigid joint joints generally have poor stability and insufficient deformation capacity, which leads to the problem that the wallboard is prone to damage under earthquake action, and the existing semi-rigid joint joints are connected with anti-seepage and thermal insulation. Poor insulation. Therefore, there is an urgent need for a semi-rigid connection node connection structure that can improve the seismic performance and has good sealing performance.
