Embodiment Construction

[0019] Such as figure 1 , figure 2 As shown, the embodiment of the composite thermal insulation board of the present invention, the composite thermal insulation board includes an inner panel 1, an outer panel 3, and a core layer 2 between the two panels. For the convenience of description, the direction of the following description is figure 1 The orientation shown has nothing to do with the actual orientation of the product in use. The ends on the upper and lower sides of the composite insulation board are tongue-and-groove 4,6 for overlapping, and the specific structure of the tongue-and-groove is the prior art, so it will not be repeated here.

[0020] The edges of the outer panels 3 on the left and right sides of the composite thermal insulation board are provided with an inward-turned bending structure 5 for docking with the corresponding composite thermal insulation board to form a groove extending along the length direction of the edge. bottom of the panel surface. ...

Abstract

The invention discloses a cold bridge-blocking composite insulation board and a wallboard. The composite insulation board comprises an inner panel, an outer panel and a sandwich layer arranged between the two panels. Two opposite end parts at the periphery of composite insulation board are provided with rabbets for overlap joint, and the edges of the outer panels at the other two opposite sides of the composite insulation board are provided with inwards-flanged bent structures which are used for the butt joint with the corresponding composite insulation board to form grooves extending along the length directions of the edges, wherein each bent structure is provided with a bottom lower than the surface of the outer panel. By adding the bent structures for forming the joint groove during the butt joint to the rabbet-free ends based on the fact that the common composite insulation board is provided with overlapping rabbets only, the invention can effectively avoid the cold bridge phenomenon generated by the air gap existing during the anterior-posterior butt joint of the traditional composite insulation boards. Besides, the invention can effectively enhance the overall insulating property of the composite insulation board.

Description

technical field [0001] The present invention relates to thermal insulation wall panels and composite thermal insulation panels for building thermal insulation wall panels. Background technique [0002] Some composite thermal insulation boards in the prior art are provided with tongue and groove at the ends of opposite sides of the composite thermal insulation board to be used for overlapping two by two when building wall panels to form an impenetrable groove-and-groove lap joint structure, and can be used in Install sealing and insulating rubber strips at the tongue and groove to prevent the occurrence of cold bridges. The groove and groove lap structures mainly include stacked, plug-in and hybrid types. The structure of such wall panels, composite insulation boards and grooves can be It is found in publication / report number CN201362893Y, CN101338607A Chinese patent literature, and the lap joint end and the lap groove end in the literature are tongue and groove. However, li...
