A light-weight external wall panel connection node

Abstract

The invention discloses a connection node of a light-weight external hanging wallboard, which relates to the field of building connection structures. The scheme includes an upper node assembly and a lower node assembly. Both the upper node assembly and the lower node assembly include connectors, L-shaped bolts, and nuts. The connectors are fixed to the main structural members of the building. On the shape bolt, the lower node assembly also includes a supporting plate, the connecting piece between the plate and the lower node assembly is fixed and supports the wallboard, and both the upper node assembly and the lower node assembly also include an elastic sleeve, and the elastic sleeve is sleeved Outside the L-shaped bolts, the elastic sleeve fits with the mounting holes provided on the upper and lower sides of the wallboard; an elastic backing plate is also arranged on the supporting plate, and the elastic backing plate is located between the supporting plate and the wallboard. The invention provides a light-weight external hanging wallboard connection node, which solves the problems of wallboard damage and L-shaped bolt failure caused by direct collision with L-shaped bolts after the wallboard is displaced, and has a simple structure and is convenient for installation.

Description

technical field [0001] The invention relates to the field of building connection structures, in particular to a connection node of a lightweight external wall panel. Background technique [0002] Lightweight external wall panels refer to multiple standard lightweight strip panel units connected to the main structure through connection nodes to form wall panels. Compared with traditional masonry walls, lightweight external wall panels are composed of multiple standard strip panels , has excellent integrity and waterproof and impermeability; at the same time, the installation of lightweight external wall panels generally adopts dry construction, which avoids wet work procedures such as on-site masonry, reduces material and labor costs, and greatly improves construction efficiency. . [0003] With the continuous advancement of the greening and industrialization of my country's construction industry, lightweight external wall panels have been favored by the engineering communit...

Problems solved by technology

[0006] (1) The fixed bolt connection nodes represented by the hook bolt connection nodes are simple in structure and easy to install. They are fixed directly through the wall panels and building structural members (I-shaped steel) through the hook bolt connection nodes, but such connection nodes will be very large. Limit the in-plane displacement of the wall panels to a certain extent. When the main structure produces a large interlayer lateral movement, the connecting node parts will be squeezed with the wall panels, which will easily lead to damage to the wall panels and yield failure of the fixing bolts, which is not conducive to maintaining the wall panels. The functions are complete, and the security of the connected nodes is reduced;

[0007] (2) Slip joints represented by steel pipe anchor connection joints have less restraint on wall panels, but the structure of such joints is complex, there are many customized parts, and generally require pre-embedded connectors inside light wall panels, The high requirements for the production process of wall panels greatly increase the production cost of wall panels and their connecting joint parts; at the same time, the installation process of such joints is cumbersome and requires high installation accuracy. The installation process needs to be completed with specific auxiliary tools, reducing Improve the installation efficiency of wall panels;
