Assembly type composite panel and heat insulation boards thereof

Abstract

The invention relates to an assembly type composite panel and heat insulation boards thereof. The assembly type composite panel comprises at least two heat insulation boards connected in sequence, each the heat insulation board comprises an inner face panel and an outer face panel, wherein a filling layer is arranged between the two face panels, and a slot is formed between the inner and outer face panels at the position of a connection end of the two adjacent heat insulation boards; a bridge connection piece is inserted in the slotting and the upper side face of the bridge connection piece is attached to the outer face panels of the two adjacent heat insulation boards, and the lower side face of the bridge connection piece is attached to the inner face panels of the two adjacent heat insulation boards, so that a connection piece does not need to be arranged at the connection end of the heat insulation boards, misplacement and deformation of the connection piece, the face planes and the bridge connection piece are avoided when the temperature changes, deformation of nails in the connection position due to shearing force is avoided, and the connection strength between the heat insulation boards is improved; and when installing is conducted, the bridge connection piece is directly installed in the slot of one heat insulation board, then the other heat insulation board is installed on the bridge connection piece, and the installation process is convenient.

Description

technical field [0001] The invention relates to an assembled composite board and its heat preservation board. Background technique [0002] With the continuous development of our country's economy, energy conservation has become an issue that our country pays more and more attention to, and building energy conservation is an important part of it; with the continuous strengthening of the country's work on building energy conservation, it is especially required that residential buildings and public buildings strictly implement the building regulations. Energy-saving standards, fully implement the design standard of 50% energy saving, and implement the energy-saving design standard of 65% energy saving in regions where conditions permit. The insulation of building walls is the most important and most effective aspect of building energy conservation. There are many cavity insulation products made of existing thermal insulation and energy-saving materials on the market, such as ...

Problems solved by technology

There are many cavity insulation products made of existing thermal insulation and energy-saving materials on the market, such as a composite board and a wall panel using the composite board disclosed in a Chinese patent with the announcement number CN 101942882 B and the announcement date of 2012.12.26. The composite board is the insulation board, and the wall panel is the composite board. The composite board includes two insulation boards and a bridge for connecting the two insulation boards. The insulation board includes an inner panel, an outer panel and a foam filling layer filled therein. The outer panel is generally made of hard materials such as cement fiberboard and fiber reinforced calcium silicate board. The tube is filled with a foam filling layer used to prevent cold bridges between the two insulation boards. The two ends of the bridge are respectively inserted into the female grooves of the adjacent connectors of the two insulation boards and fixed by nails. It passes through the panel and is fixed on the bridge. Due to the large difference in expansion coefficient between the panel, the connector and the bridge, the panel, the connector and the bridge will expand or expand to different degrees as the temperature changes during use. Shrinkage will cause dislocation and deformation of the nail installation holes on the panels, connectors and bridges, and the nails in the installation holes will be subjected to shear force, which will easily deform the nails or even fatigue fracture, resulting in the joints of the insulation boards in the composite board. disengagement problem
