The height of the house building is continuously increased, however, along with the increase of the building height, the construction and the heat insulation performance of the outer wall heat insulation project are seriously tested. At present, super high-rise buildings are all shear wall structures, an outer wall structure and an outer heat insulation layer are respectively constructed, and then the outer wall structure and the outer heat insulation layer are combined through bonding. The cohesiveness of the outer wall structure and the outer heat-insulating layer is reduced along with the time, and the problem that the outer heat-insulating layer falls off can occur, so that safety accidents are caused.
In order to avoid bonding failure of an outer wall structure and an outer heat-insulating layer, the prior art provides a composite heat-insulating template cast-in-place concrete heat-insulating system, namely a heat-insulating structure integrated construction technology, wherein the composite heat-insulating template is a permanent outer template, concrete is poured on the inner side of the composite heat-insulating template, a leveling layer is further arranged on the outer side of the composite heat-insulating template, and then construction of an anti-cracking layer and a decorative surface layer is carried out. Finally, the composite heat-insulating template is firmly connected with the concrete through a connecting piece.

However, in the construction of super high-rise buildings, the story height of a standard story is higher, the width of the composite heat-insulating template is 600mm, the maximum length of the composite heat-insulating template is 3000mm, the thickness of the composite heat-insulating template is 12-15mm, and the composite heat-insulating template is heavy in weight, large in size and difficult to install and construct. The installation engineering of the composite heat-insulation template mainly has the following problems: firstly, when the composite heat-insulation template is installed on an ultra-high layer with the height of more than 3m, at least two composite heat-insulation templates are needed for assembling each layer of vertical heat-insulation layer, the composite heat-insulation template is heavy, and the labor intensity of manual carrying is too high, so that the engineering progress is influenced. Secondly, need set up operation platform alone when carrying out the construction of compound incubation template, and receive the restriction of building outer protection frame, lead to operation platform space narrow and small, increased the construction degree of difficulty. In addition, when two vertical composite heat-insulating templates are transversely spliced, a splicing seam is generated, and meanwhile, a cold bridge phenomenon is generated when each layer of composite heat-insulating template is spliced, so that the construction quality is difficult to ensure. The cold bridge phenomenon mainly means that when the building outer enclosure structure conducts heat with the outside, because the heat transfer coefficient of some parts in the enclosure structure is obviously larger than that of other parts, the heat is intensively and quickly transferred from the parts, and thus the air conditioning, heating load and energy consumption of the building are increased. And finally, the constructors have great potential safety hazards when working at high heights outside the super high-rise building, and the construction difficulty is increased along with the increase of the floor height.
Therefore, a construction method of a composite heat-insulating template is needed to solve the above problems.
