Foam concrete panel, rabbet connecting piece and wallboard externally hung structure

Abstract

The invention discloses a foam concrete panel, a rabbet connecting piece and a wallboard externally hung structure. The rabbet grooves extended along the direction of a panel surface are respectively arranged on the upper end and the lower end of the foam concrete panel, the rabbet groove is a straight-through groove, the rabbet connecting pieces are respectively fixed on the upper end and lower end of the foam concrete panel body on a beam of the house, the rabbet connecting piece comprises a main part overhung to the outside of a house and a tongue protruded on an overhanging end of the main part, and the tongue is in guiding cooperation with the rabbet groove along the plane direction of the foam concrete plane body. While in use, the rabbet connecting piece is fixed on the beam of the house, the tongue on the rabbet connecting piece can form a corresponded guide rail structure at the upper side and the lower side of the installation position of the foam concrete panel, and then the foam concrete plane is introduced to slip into an area between the rabbet connecting pieces through the guiding cooperation between the tongue and the rabbet groove, so that the construction efficiency of the wallboard externally hung structure is accelerated, and the construction cycle is shortened.

Description

technical field [0001] The invention relates to a foam concrete wallboard, a tongue-and-groove connector adapted to the foam concrete wallboard and a wallboard external hanging structure using the foam concrete wallboard. Background technique [0002] At present, the wallboards used in the dry-hanging construction on buildings are hung and fixed on the main structure through metal inserts. For example, a Chinese patent with application number 201210072729.0 discloses a light-weight aerated concrete based on autoclaved The dry-hanging self-insulation curtain wall of the board includes the ALC board (autoclaved lightweight aerated concrete board). The parts are connected with a pressure plate through bolts, and the pressure plate is fixed on the angle steel of the main structure, that is, the ALC plate is fixed on the main structure through the pressure plate. However, the bolts fixed to the built-in embedded parts are inlaid on the ALC plate by means of forced installation. ...

Problems solved by technology

However, the bolts fixed to the built-in embedded parts are inlaid on the ALC plate by means of forced installation. If these bolts have been installed before the ALC plate is transferred, then because the surface of the existing ALC plate is flat, and The bolts fixed to the built-in embedded parts protrude from the surface of the ALC plate, so the exposed part of the bolt will form a circle of spaced protrusions on the surface of the ALC plate. When it is necessary to stack several ALC plates on the When transported together, the protrusions on the two adjacent ALC plates will make the ALC plates cannot be stacked together stably, affecting the transportation and handling of the ALC plates; if the bolts are installed on the ALC plates at the construction site, then Each bolt needs to be installed on the ALC board correspondingly before construction, which prolongs the time for on-site preparation of the ALC board and reduces work efficiency; at the same time, after the built-in embedded parts are connected with the roof beams, a cantilever structure suspended outside the main structure will be formed , and the ALC board is fixedly connected to the overhanging end of the built-in embedded part, and the ALC board will bend the built-in embedded part under the influence of its own weight, so that the inner surface of the ALC board is damaged, resulting in the external hanging structure of the entire wall panel The reliability and integrity of the connection are destroyed, which will reduce the heat insulation effect of the wall panel and shorten the service life of the wall panel
