Problems solved by technology
The traditional thermal insulation board paste construction technology adopts the splicing and pasting method of the boards. This splicing method causes a certain gap between two adjacent boards, which cannot achieve complete sealing, and the entire insulation layer cannot achieve integrity, and it is easy to generate cold and heat bridges. , so that the wall cracks and the thermal insulation performance is greatly reduced; at the same time, rainwater can easily enter the wall from the gaps between adjacent panels, and the existence of gaps makes it difficult for the thermal insulation panels to resist the influence of negative wind pressure, which in turn will lead to thermal insulation panels. The falling off, which has a great adverse effect on the insulation system

Embodiment Construction
[0025] Below in conjunction with accompanying drawing 4, the present invention will be further described in detail. The thermal insulation board anti-crack melting seam technology of the present invention, in building thermal insulation construction, selects polyurethane board as the thermal insulation board, and when fixing the thermal insulation board, the thermal insulation board is staggered by the standard part 1 For connection, a certain gap is reserved between adjacent thermal insulation boards. After the thermal insulation boards are fixed, the standard parts are taken out, and polyurethane material is poured into the gaps of the boards by manual pouring to connect adjacent thermal insulation boards.
[0026] Construction method step of the present invention:
[0027] 1) Prefabrication processing or construction site processing insulation board;
[0028] 2) Pretreatment of building base surface, cement mortar leveling;
[0029] 3) According to the projected size of th...

The present invention is anti-cracking seam-jointing technology for heat insulating plates and belongs to the field of building heat insulating technology. The anti-cracking seam-jointing technology is that after heat insulating plates are fixed onto building, polyurethane material is poured to the remained joints to connect the heat insulating plates so as to form one waterproof seamless system, which has no heat bridge, no cracking and deformation, and raised heating insulating and waterproofing effect.
Description
technical field [0001] The invention belongs to the technical field of building heat preservation, and in particular relates to a melting seam technology of heat preservation boards. Background technique [0002] The method that the existing building wall insulation generally adopts is to paste thermal insulation boards such as prefabricated boards and composite processed boards on the building base. The traditional thermal insulation board paste construction technology adopts the splicing and pasting method of the boards. This splicing method causes a certain gap between two adjacent boards, which cannot achieve complete sealing, and the entire insulation layer cannot achieve integrity, and it is easy to generate cold and heat bridges. , so that the wall cracks and the thermal insulation performance is greatly reduced; at the same time, rainwater can easily enter the wall from the gaps between adjacent panels, and the existence of gaps makes it difficult for the thermal ins...
