Abstract

The utility model discloses an insulating wall which is cast in polyurethane rigid foam on site by adopting a dismantling-free mould needing not to be fixed by a padding block. The insulating wall comprises a basal wall surface, a cast polyurethane insulating layer, a high-density fiber-cement board and a finishing coat, wherein the high-density fiber-cement board is connected with the basal wall surface by special expanding screws in an anchoring way; the high-density fiber-cement board can be rapidly supported to be fixed; the cast polyurethane insulating layer can be flexibly adjusted in thickness gap and the flatness; wall surface leveling or line snapping is not needed; and the dismantling-free mould needs not to be supported by the padding block to preserve the heat of the thickness gap and adjust the flatness of the cast polyurethane insulating layer. The insulating wall is waterproof and fireproof and is moulded in one step with easier and simpler procedures and least time and labor, thereby being convenient for popularization.

Description

On-the-spot no cushion block is fixedly exempted from form removal cast polyurethane hard bubble body heat-preserving wall

Technical field

The utility model belongs to thermal insulation, the water proof building component technology field of site preparation, is specifically related to the no cushion block in a kind of scene and fixedly exempts from the form removal pouring polyurethane heat insulating wall.

Background technology

The energy of China is poor relatively and in short supply, is accompanied by global energy, pressure and China's rapid economic development that environment brought, and energy-saving and emission-reduction have become a fundamental state policy of China.Because China has a large population, construction scope is big and building heat preservation is poor, makes architectural energy consumption account for more than 30% of social total energy consumption, from now on along with people to live, the office occupancy comfort level requires improves constantly, building energy consumption also will further strengthen.Therefore, building energy conservation is imperative.

Party and state has paid much attention to building energy conservation, relevant policies and regulations of building energy conservation and energy-conservation 50% compulsory standard have successively been formulated, and progressively promote energy-conservation 65% new standard, also will progressively improve the standard of building energy conservation from now on, the building energy conservation of China is reached or near the standard of West Europe advanced country, along with improving constantly of building energy-saving standard, research and application heat insulating material and heat-preserving wall have become the emphasis of building energy conservation.

Be the heat-preserving wall of main flow with the external pasting polyphenyl plate at present, because of its coefficient of thermal conductivity is bigger, the not too suitable high building of energy conservation standard.And polyurethane in building energy saving field, earns widespread respect, and applies in the building more than 65% energy-conservation with its distinctive low heat conductivity, high-adhesion and good water proofing property.

Polyurethane heat-insulation, at present on building energy conservation external wall outer insulation application technology, mainly contain in-situ spraying method, cast-in-site method and stick method several, the cast-in-site method has the movable die plate method again and exempts from the form removal method, but with regard to its insulation, water tight integrity, safety and firmness, easy construction, exempting from form removal cast-in-site method, is the developing direction of external wall outer insulation from now on.

At present the disclosed form removal cast-in-site polyurethane heat insulating wall of exempting from exists basic unit's metope and needs cement mortar screeding, must play control line on metope, and fixing non-dismantling formwork must be with prefabricated cushion block support etc., the deficiency that working procedure is loaded down with trivial details.

Publication number 100999918 patents of invention disclose a kind of pouring polyurethane heat insulating wall, it is characterized in that, this body of wall is basic unit's body of wall, cement mortar screeding layer, cast polyurethane insulation layer, high-density fiber cement board, finish coat from inside to outside successively.Its working procedure is, draw fabric swatch figure according to thermal insulation wall surface earlier, press fabric swatch figure setting-out again on thermal insulation wall surface, then on metope, paste cushion block again by fabric swatch figure, and adjust the thickness of each cushion block according to insulation layer thickness and degree of plainness for wall surface, and all cushion block surfaces are on the plane, the back uses anchor clamps and expansion bolt that cement board is fixed again, last slit cast polyurethane between cement board and body of wall, its working procedure is somewhat loaded down with trivial details.

The utility model content

At present scene exempt from that basic unit's metope that the form removal pouring polyurethane heat insulating wall exists needs cement mortar screeding, must play control line on metope, non-dismantling formwork fixes must be with the prefabricated loaded down with trivial details deficiencies of working procedure such as cushion block support, the utility model without the metope levelling, not be used in and play control line on the body of wall, also need not paste prefabricated cushion block on the wall but fix non-dismantling formwork with the solid plate instrument of special-purpose metal, working procedure is easy, labor and material saving, pollution-free, wall thermal insulating, waterproof, fire prevention one-shot forming.

The utility model adopts following technical scheme:

On-the-spot no cushion block is exempted from fixedly cast polyurethane hard bubble body external wall outer insulation body of wall of form removal, is made of basic unit's body of wall, cast polyurethane hard bubble body insulation water-proof layer, high density fiberboard cement board, finish coat successively from the inside to surface.It is characterized in that: the high-density fiber cement board is anchored into the basic unit metope and is connected by the special use silk that expands.Solid plate instrument with special use fixes cement board on basic unit's metope, basic unit's metope need not cement mortar screeding, must on basic unit's metope, not play the cloth printed line yet, reserve the space of cast polyurethane hard bubble body between basic unit's metope and the cement board and adjust the cement board surface glacing flatness, also cushion block that need not be prefabricated, working procedure is easy, labor and material saving.

The solid plate instrument of described special use is to adjust pin spiral shell, the bloated silk of special-purpose anchoring and level(l)ing bubble by laths of metal, insulation layer thickness and glacing flatness to combine.The solid plate instrument of this special use can be smooth vertical with degree of plainness for wall surface rapid adjustment cement board surface according to insulation layer thickness, and with firm being fixed on basic unit's body of wall of cement board, can make things convenient for the lower fixed slab instrument of tearing open fast after the urethane cures, changing the next one over to recycles, the described special-purpose anchoring bloated silk of silk for being manufactured by nylon material that expand, can be eliminated the metal silk cold bridge that expands at its non-corroding, low heat conduction.The no cushion block in described scene is fixedly exempted from form removal cast polyurethane hard bubble body heat-preserving wall, comprises following operation:

1. according to heat-preserving wall, draw cloth template figure;

2. according to cloth template figure, manufacture the high-density fiber cement sheeting;
