Description

Steel work and concrete frame structure body of wall cast-in-place foamed concrete fireproofing heat preservation structure

Technical field

The utility model relates to construction wall structure, particularly construction wall insulation, fire prevention, sound insulating construction; Specifically, be that steel work and concrete frame structure body of wall foam concrete coat column and keel fireproofing heat preservation structure.

Technical background

The main position of building heat preservation is a body of wall, particularly outer body of wall.Interior body of wall mainly is sound insulation, and is then less demanding to insulation.No matter be the exterior wall interior wall, fire prevention is of equal importance with heat preservation and soundproof.

At present, in order to promote building energy conservation, steel construction wall of China and concrete frame structure body of wall all are faced with insulation and the huge contradiction of fireproof.Because wall heat insulation material is foamed plastics mostly, no matter insulation layer is outer subsides or plug-in, perhaps there is disaster hidden-trouble invariably in the interior filling of steel work.CCTV's annex big fire, Chinese science and technology new shop big fire, a series of wildfires such as the Olympic Sports Center, Jinan big fire make us startling, are caused by the foamed plastics wall thermal insulating invariably.Therefore, approach foamed plastics, and absolute fire prevention is not fired with heat insulation effect, and the foam concrete of sound insulating and absorbing excellence, replace foamed plastics, be the industry common recognition.How foam concrete forms wall body structure, really uses on the wall self-insulation, and it is unified to obtain insulation and fireproof, does not also have satisfied or desirable scheme so far, has blocked foam concrete and has replaced the paces that foamed plastics is used for wall thermal insulating.

Foam concrete prefabricated panel heat-preserving wall structure though in China certain application is arranged, because cost is very high, is never promoted on a large scale, is difficult to popularize.Except that a small amount of villa and large scale industry building, general industry building and civilian construction are all less than using.Foam concrete is cast-in-situ thermal-insulated to have very big advantage, and speed of application is fast, cost is low, do not need factory building, investment is little, but nowadays only is used for roof insulation layer and floor heating heat insulation layer, seldom is used for the insulation of building enclosure body of wall.Application number is 200410027613.0 patent of invention " foam concrete body of wall pouring technology technology ", foam concrete body of wall pouring technology technology has been proposed: " according to the actual needs at scene foam concrete wall mould, template are installed earlier, then the foam concrete pumping for preparing are poured in mould or the template.Mould, template can be made different shape according to actual needs, behind supersolidification, remove mould or template, and whole body of wall is built the work of building and finished ".This scheme is too simple, and does not propose concrete wall thermal insulating structure and be suitable for body of wall type (as brick masonry wall, steel structure body of wall, concrete frame body of wall etc.) to be unfavorable for practical application.Simultaneously, this scheme is emphasized form removable, tears permanent formwork (or panel) open and ignored bigger the exempting from of actual application value, has limited the foam concrete cast-in-situ wall and has promoted widely.The national standard atlas " steel house (two) " of China's promulgation in 2008; though foam concrete grouting steel house wall structure is arranged; but the panel of its body of wall lightgage steel joist column both sides directly is fixed on the keel; foam concrete does not coat lightgage steel joist fully; keel can not get effective protection of foam concrete when fire, and can form the cold bridge of body of wall internal-external heat exchange.Simultaneously opening not on its keel web has been cut apart foam concrete, and foam concrete can't be flowed in body of wall, and not only speed of perfusion is slow, and has destroyed the globality of foam concrete insulation layer, has reduced heat insulation effect.In addition, this atlas foam concrete cast-in-situ wall only is adapted to steel work, and does not contain concrete frame structure, is unfavorable for enlarging its range of application.

The utility model content

Major technique innovation scheme of the present utility model has two:

1,, and between the template or panel that are fixed thereon, the bridge cut-off cushion block is set at steel structure column and steel joist, concrete frame column and concrete component keel or steel joist.The bridge cut-off cushion block makes between column or keel and template or the panel and forms spacing, and foam concrete just can coat column and keel after filling this spacing.The bridge cut-off cushion block can be selected the tabular inorganic heat insulation materials of lightweight such as the higher foam concrete of intensity, foam glass, foamed ceramics, float stone for use.

2, in the web upper shed of steel structure centre keel, concrete cement member centre keel, make the foam concrete slurry can pass centre keel, in body of wall, flow freely.

Specifically, cast-in-place coating column of the utility model foam concrete and keel self-heat conserving fire-proof wall structure is achieved in that

A kind of steel work and concrete frame structure body of wall cast-in-place foamed concrete fireproofing heat preservation structure, it is characterized in that inside and outside both sides at wall stud and keel, pass through certain thickness bridge cut-off cushion block with fixture, panel or template are fixed on column and the keel, form die cavity between interior outer side panel or the template, also form die cavity between column and keel and template or the panel, with the pumping of foam concrete slurry or manually inject in the die cavity, coat column and keel, form foam concrete fireproofing heat preservation body of wall.The keel that adopted are the web open-type, promptly have a plurality of holes on the web of keel.Be provided with the bridge cut-off cushion block between wall stud and keel and panel or template, this bridge cut-off cushion block can be bulk or slab foam concrete, foam glass, foamed ceramics.

The beneficial effects of the utility model:

1, because the foam concrete coefficient of thermal conductivity is low, both be incubated, and can intercept the thermal radiation in the fire again, insulation is fire prevention again.Simultaneously, it does not directly contact column and keel with panel, also eliminated the formed cold bridge of column, has improved heat insulation effect.Therefore, it is the key structure that foam concrete coats column and keel that the bridge cut-off cushion block is set, can solve the building fire protection of always perplexing domestic and international builing industry and the contradiction of insulation preferably, found and made the two unified outlet, realized the unification of building fire protection and insulation, and integrated finishing for building fire protection both domestic and external and insulation have solved a difficult problem, led direction.
