Background technology
Body of wall is different according to the structure stress situation, is divided into load bearing wall and nonbearing wall.All walls that directly bears roof, top, load that floor transmits claim load bearing wall; All walls that does not bear upper load claim nonbearing wall, and nonbearing wall comprises partition wall, infilled wall and curtain wall.Partition wall plays a part to separate the interior space, should satisfy the requirements such as sound insulation, fire prevention, and its weight is subjected to by floor or joist support; Infilled wall generally is filled between the post wall of frame construction; Curtain wall then is the lightweight exterior wall that hangs between external skeletal or the floor.Simultaneously at present in the Practical Project, when often running into body of wall and have the bearing wall performance, need to have the performances such as light weight, fire prevention, insulation, sound insulation concurrently.
At present, the kind of light partition wall material that is used for nonbearing wall on the market is a lot, in space decoration main use Thistle board partition wall, calcium silicate board partition wall and carpentery workshop partition wall etc. are arranged.All kinds of Light Walls are had nothing in common with each other at aspect of performances such as price, sound insulation value, metope carrying, hanging force and fire prevention, waterproof, but compare with clay solid brick, its common characteristics are from heavy and light, every square metre weight generally than the light 5-9 of clay solid brick wall doubly, and have the performances such as good heat insulation, insulation, fire prevention, anti-aging, anti-impact force, in engineering practice, be used widely.Light partition wall just develops towards supporting, seriation, easy to assemble, easy construction direction at present simultaneously.The novel light walling mainly is to make with raw materials such as cement, lime, slag, sand, flyash, strings, generally has native, energy-conservation, the sharp useless advantage of joint, the utilization of Novel light wall body, with fundamentally change traditional materials for wall fetch earth in a large number ruin the field, consume the energy, the situation of contaminated environment, can also alleviate structural weight per square meter, reduce the building comprehensive cost.
In sum, need at present a kind of easy construction of invention, fast, the light weight of speed of application badly, have simultaneously the performances such as fire prevention, insulation, sound insulation, can be used as the Light Wall that load bearing wall or nonbearing wall use.
Summary of the invention
The purpose of this utility model is to make up and utilizes the wire mesh mortar fire wall to have good fireproof performance, reinforced concrete wall to have good load-carrying properties, air bubble mix light-textured soil has the performances such as light weight and good heat insulating and sound insulating, interlayer ventilation stack and body of wall air chimney and has good energy-conserving and environment-protective characteristic etc., invent a kind of easy construction, fast, the light weight of speed of application, have simultaneously the performances such as fire prevention, insulation, sound insulation, can be used as the lightweight core reinforced concrete wall that load bearing wall or nonbearing wall use.
In order to realize above-mentioned technical purpose, the utility model has adopted following technical scheme:
A kind of lightweight core reinforced concrete wall comprises: the inside and outside wallboard of steel concrete arranges respectively inside and outside metope on the outer facade of inside and outside wall board; Inside and outside wall board adopts screw rod to fix, and screw limiting end and nut adopt the countersunk head mode, and the two ends lateral surface is parallel with inside and outside metope respectively; Described inside and outside metope is the mortar fire wall;
Inside and outside metope gauze wire cloth is set respectively in the inside and outside metope; Inside and outside metope gauze wire cloth is arranged at mortar 1/3rd of the inside and outside wall surface mortar layer thickness of preventing fires, and near inside and outside wallboard one side of steel concrete;
Ventilation stack is set between inside and outside wall board, is to be enclosed by dividing plate to form, and between dividing plate and the inside and outside wall board support is set, and at inner wall panel the air chimney that connects with ventilation stack is set, and end ports of ventilating ducts arranges the Easy dismountable closing cap.
Cast in situs cellular concrete lightweight core between inner wall panel and the dividing plate, between side fascia and the dividing plate.
Cellular concrete, that foamed system by air bubble machine fully foams blowing agent with mechanical system, and foam evenly mixed with cement paste, then the pumping system through foaming machine carries out cast-in-place construction or mould molding, through the formed a kind of novel light heat insulating material that contains a large amount of sealed porositys of natural curing.It belongs to the air bubble-shaped thermal insulation material, and outstanding feature is the foam hole that forms sealing at inside concrete, makes concrete light materialization and thermal insulation separation thermalization.In precast reinforced concrete structure, can adopt cellular concrete as inner core, can make it have the heat insulation superperformance of high-strength light.
Wire lath mortar fireproofing technique especially is used widely in the structural steelwork in engineering at present; after adopting wire lath mortar fireproofing technique; the anti-impact force of energy Effective Raise fire resistant coating, the integrality of protection fire resistant coating guarantees safety of building and durability.
Rationally sandwich establishment ventilation stack and body of wall air chimney in body of wall can be taken away and reduce enter indoor heat summer, thereby reduce energy consumption for cooling.Close all ventilation openings winter, hollow plank becomes the air space of sealing, has greatly improved the thermal insulation ability.
That the body of wall that the utility model relates to has is lightweight, speed of application is fast, has significant barrier property, fire prevention, insulation, soundproof effect are good, crack resistance and anti-deformation are good, can be used as load bearing wall or nonbearing wall and use, symbol building construction material will be to the requirement light-duty and development of heat preservation energy-saving aspect.
