Description

Sandwich thermal- and sound-insulation panel member for reinforced concrete

These novel prefabricated units that belong to construction work

At the peripheral structure exterior wall of BUILDINGS IN COLD AREAS thing and the major function of roofing is load-bearing and insulation, and the major function of interior separation structure interior wall and floor is load-bearing and sound insulation.The conventional practice of these structures all is to adopt homogenous material, as red anvil, steel concrete etc. make, therefore, make them reach not only load-bearing simultaneously but also be incubated or the multi-functional requirement of not only load-bearing but also sound insulation all has certain difficulty, people are to the compound use of two or more materials for this reason, once carried out a large amount of research, but all the thermal property difference because of the strength character of structural meterials and heat insulating material is too big, be difficult to take into account mutually unification, even exempt to be combined with each other by force, also be easy to generate various hidden danger, effect is not good enough, and single light weight aggregate concrete material, though can satisfy load-bearing simultaneously, the double requirements of insulation, because of the lightweight aggregate price more expensive, consumption is excessive, applies to be restricted.How finding a kind of middle transition way to fill up this blank, is an important subject extremely to be solved, and this is novel to be exactly with this end in view to develop.

This novel purpose is the sandwich member that will produce a kind of steel concrete, make its steel concrete shell can satisfy the requirement and the life requirement of various mechanical properties, the energy-saving heat preserving that the insulation of the ultralight of sandwich part, sound insulation materials can satisfy any standard requires and the sound isolation requirement when using, and make the web of structural element with the light weight aggregate concrete that can satisfy load-bearing, heat preservation and soundproof requirement on a small quantity simultaneously, steel concrete shell and sandwich heat preservation sound insulation materials can effectively be combined with each other.Thereby, make member can reach the dual function of use requirement of load-bearing, insulation or load-bearing, sound insulation fully, and don't have any hidden danger.

Its practice sees shown in the accompanying drawing 1～16, is member is made double-deck armored concrete slab face 1,2, and plate face thickness 3～4cm can be prestressed, and is also can right and wrong prestressed.Between two layer concrete plate faces 1,2; making web 3,4 with the light concrete that self also has insulation, sound insulation function connects; its lightweight aggregate can be haydite or float stone; make between this light concrete web 3,4 and the double steel bar concrete plate surface 1,2 and can constitute a kind of primary structure member that meets the mechanics requirement; can make web 3,4 also have the function that stops thermal energy transfer again; its thermal technology requires should be to guarantee that when the outdoor lowest temperature, indoor web 3,4 places not dewfall are principle.After pressing from both sides between the double layer concrete plate face 1,2 again with the various different lightweights that require, high-efficiency insulated, sound insulation materials 6, as: swelling perlite powder and goods thereof, glass wool, rock wool and goods thereof, foamed plastics and goods thereof,

Stone, gas concrete piece etc., wherein permeability resistance is poor, and bibulous material should wrap up with plastic sheeting in advance.Just finally formed with three kinds of energy-efficient composite components that material is compound with load-bearing, insulation, sound insulation function.This class A of geometric unitA can be single load bearing plate Fig. 1 of duplexing font section; Also can be bidirectional stress plate Fig. 4 of nine-squares beam shape; Can make the side fascia of load-bearing, insulation unification, roof panel; Can make floor, the inner wall panel of load-bearing, sound insulation unification.

This novel key technology is:

1, the structure of web:

Web 3,4 can be prefabricated with light concrete, reserves in the future the fine steel rib 10 that connects with other cast-in-situ concrete around it; The ordinary concrete that also can be light concrete and plate face 1,2 is distinguished cast-in-place moulding simultaneously.

When member was stripe board Fig. 1 of duplexing font section of single load bearing, its prefabricated light concrete web 3 was strips; When member is rectangular slab Fig. 4 of bidirectional stress, its prefabricated light concrete web be by ten, the nine-squares beam that combines mutually of ┬, ┌

font plate

7,8,9.

At severe cold area, when member is when doing side fascia or roof panel use, in order to prevent that better severe winter from producing the dewfall phenomenon at indoor web place because of cold bridge, can be designed to prefabricated light concrete web with triangle space Fig. 7 or with the pattern of square space Fig. 9, shape space, garden Figure 11, and in these spaces, also fill out with efficient light heat insulation material 5, to improve its heat-proof quality.

When sandwich heat preservation, when sound insulation materials 6 is the lightweight board-like material, can in the manufacturing process of big plate, when sandwich material 6 is filled, reserve the position, space of

web

3,4 or 7,8,9.Use the cast-in-place moulding web of light concrete then therein, the making that makes whole large board member is to adopt plate face 1,2 ordinary concretes and

web

3,4 or 7,8,9 light concretes to distinguish cast-in-place moulding simultaneously.When member is when doing inner wall panel and floor use, owing to there is not the strict demand of heat-insulating property, as long as can satisfy the condition of sound isolation requirement, therefore can also in the space of reserving

web

3,4 or 7,8,9, also directly water ordinary concrete, make whole production technology simpler.

2, the construction of double steel bar concrete plate surface and sandwich lightweight, high-efficiency insulated sound insulation materials inserts

The production of this new type of component is to adopt the production technology moulding that lies low, the just moulding on the pedestal of ground of bottom plate face 1 of its double layer concrete plate face 1,2, and the moulding of top plate face 2 can not be with traditional formwork way.Because if like this, after concrete casting is intact, template just can't be removed, for this reason, the present invention adopts with sandwich light thermal-insulation, sound insulation materials 6 full ways of filling, and so the bearing surface when allowing these materials as top plate face 2 concrete cast-in-situs is when the shake of top plate face 2 concrete is smash, must use special weight lighter, equipment construction is smash in the less flat board shake of compressive load per unit area.After top plate face 2 concrete castings are intact, these light thermal-insulations, sound insulation materials 6 also just are clipped in the two layer concrete plate faces 1,2 naturally, final formation has double steel bar concrete plate surface 1,2,

light concrete web

3,4 or 7,8,9 sandwich heat preservation, sound insulating panel member.

When because of stressed needs, need increase

web

3,4 or 7,8,9, when satisfying the rigidity requirement of structure, when maybe needing to make the domatic member, can sandwich insulation, sound insulation materials 6 is built on stilts.Built on stilts way can be selected arbitrarily, with till reaching the height or the gradient that needs, and then at the concrete of its surface construction top plate face 2, can make increasing or the domatic member of needing.

This novel advantage is:

1, itself makes the connection web of inside and outside two layers of armored concrete slab face with regard to light concrete owing to having adopted with insulation, sound insulation value, effectively solved cold district and connect the serious cold bridge condensation trouble that produces because of adopting the relatively poor material of ordinary concrete or other thermal resistances to carry out structure as web, also reduced the consumption of more expensive lightweight aggregate to greatest extent, for study this class not only the building composite construction of economy but also effectively winter protection started a new road.

2, owing to can directly be compounded in all kinds of light thermal-insulations, sound insulation materials in the structural element,---insulation or load-bearing---unification of sound insulation that makes member itself just accomplish load-bearing, this compares with traditional structural form of making insulation, sound insulation materials in addition in component surface, can save material in a large number, reduce working procedure, reduce structural thickness, speed up the work, reduce cost.

3, this class A of geometric unitA is if use as side fascia, can be when producing, directly decorative material is laid on the pedestal, when pouring outer concrete plate face, ornament materials and concrete plate surface are directly bonded together, be commonly called as " anti-play ", at this moment, ornament materials and concrete plate surface bonding firmly, and save time, material-saving.
