Abstract

A cast-in-situ foam concrete structure for external wall heat insulation is characterized by comprising a wall, fixing parts, a cast-in-situ foam concrete heat insulation layer, a protective layer or decorative layer. The protective layer or decorative layer can be decorative panels such as large-sized ceramic tiles, marbles, granite, aluminum-plastic composite boards, GRC cement decorative boards, veneer fiber cement boards and metal decorative boards, or can be non-decorative panel such as tempered fiber cement boards, GRC cement boards and calcium silicate boards and coating layers, or can be coating layers after formworks are removed. The fixing parts can adopt direct type, frame type or adhesive type fixing parts and fixing structures for hanging marble and granite plates or other decorative plates. Fixing structures for formworks can adopt fixing structures for steel formworks, bamboo formworks and composite formworks.

Description

External wall outer insulation cast-in-place foamed concrete structure

Affiliated field

The utility model relates to the outer insulation construction of a kind of external wall, particularly adopts the cast-in-place external heat preserving structure for exterior wall of foam concrete.

Technical background

External wall outer insulation both domestic and external adopts outer the subsides or plug-in plastic foamboard at present mostly, and then whitewashes decoration.Because the inflammability of foamed plastics has caused countless fire, wherein super-huge fire such as CCTV's annex fire, the Olympic Sports Center, Jinan fire etc. cause by foam insulation.The insulation of building body is becoming increasingly acute with the contradiction of fire, has become significant problem anxious to be solved, and the cry of eliminating foamed plastics in building heat preservation grows with each passing day.

Foam concrete is raw material with cement, secure and non-combustible, and insulation approaches foamed plastics, integrates excellent properties such as fire prevention, insulation, antidetonation, sound-absorbing sound insulation, is that the best of foamed plastics building heat preservation replaces product.Therefore, wideling popularize foam concrete in building heat preservation is the inexorable trend that develops both at home and abroad.

Foam concrete is cast-in-place to have advantage such as do not need workshop, equipment, investment is little, operating personnel are few, has obtained to use widely in China.But foam concrete is cast-in-place at present all is to be used for roofing, ground insulating layer, and is not applied to external wall outer insulation, and the application of field of thermal insulation still belongs to blank outside exterior wall.Yet external wall outer insulation but is first emphasis of building heat preservation.The difficult point of building heat preservation also is an external wall outer insulation.So far, except the foamed plastics of initiation fire, also there are not better external wall outer insulation method and corresponding insulation construction.Foam concrete cast-in-place outside exterior wall field of thermal insulation can not use so far, be that a very big loss and lack is shaken.

Simultaneously, building dry-hang stone, ceramic tile, colour concrete plate curtain wall because the obstruction of fixture and keel makes dry-hung plate and body of wall form the spacing of 3cm～10cm, and all is not incubated processing in the spacing, are great defectives.

The utility model patent content

The purpose of this utility model is exactly to overcome the fire problem of foamed plastics external wall outer insulation existence and the problem of cladding curtain wall heat insulating ability difference, and a kind of structure that adopts cladding curtain wall fixed plate is provided, and carries out the cast-in-place external heat preserving structure for exterior wall of foam concrete.

The utility model is achieved in that this structure is made up of body of wall, fixture, cast-in-place foamed concrete insulation layer, topping or decorative layer.

Carry out at needs on the metope of external wall outer insulation, with fixture steel form is installed, or Bamboo Formwork, or composite shuttering, or the big specification ceramic tile that plays template action is installed, or marble, or granite, or aluminium-plastic panel, or the GRC cement decorative plate, or the facing fiber cement board, or metal lagging etc. exempts to tear open the made from permanent ornamental moulded panel; The pressurization fiber cement board that plays template action also can be installed, or the GRC cement board, or the non-ornamental permanent panel of exempting to tear open such as calcium silicate board with microporous.Form certain spacing between template or panel and metope, the spacing size is according to the requirement design of local building heat preservation.The foam concrete slurry is poured in the formed cavity of above-mentioned spacing, has just formed the foam concrete external wall insulating layer after the air-set.Panel is not removed, and becomes topping or decorative layer.If adopt template to replace panel, foam concrete sclerosis rear pattern plate is then removed, and the foam concrete insulation layer adds mortar cover and application layer in addition.

Above-mentioned fixture and corresponding fixed structure at fixing various templates of metope and panel can adopt the fixture and the fixed structure of cladding marble and granite plates, as direct-type, or back hanging type, or stick formula fixture and fixed structure; The fixing fixture and the fixed structure that can adopt template to install of template.

The utlity model has following advantage:

1, replaces the foamed plastics heat insulating material with the cast-in-place foamed concrete heat insulating material, the inflammable initiation fire of foamed plastics, easily aging atrophy, easy deficiency such as come off have thoroughly been solved, integrate excellent properties such as insulation, fire prevention, sound insulation, energy-absorbing antidetonation, can solve building heat preservation and fireproof contradiction substantially, for outlet has been found in the outer insulation of external wall.

2, with the traditional external wall outer insulation technology of cast-in-place replacement, save the production of articles link, simplified external wall outer insulation technology, the polyphenyl foam plastic outer wall of original widespread usage is approached once cast-in-place the finishing of multiple working procedure boil down to of the heat preservation method of plastering, technology is simple, and is easy to implement, labor and material saving.

3, greatly reduce the cost of external wall outer insulation, have good economic benefit.

4, once construction can be protected the lifelong insulation of building, and insulation layer and same life-span of building have overcome the defective that the foamed plastics insulation need repeatedly be overhauled.
