Abstract

The invention provides a lightweight fireproof insulation wall made by pouring inorganic foamed slurry into a chamber formed by steel mesh members supported by a light steel keel frame. The lightweight fireproof insulation wall is disposed within a framework formed by building pillars and beam slabs. Each steel mesh member comprises a mesh plate, reinforcing ribs, connecting strips and a long prismatic mesh; the mesh plate, the reinforcing ribs, the connecting strips and the long prismatic mesh are mutually-acting steel mesh parts made of strip steel by special equipment; the directions of the adjacent long prismatic meshes are regularly changed; the inorganic foamed flurry is made by combining foam liquid added mixed cement slurry. By means of the technique where the inorganic foamed slurry is directly poured into the chamber formed by the steel mesh members supported by a light steel keel frame, the wall is structurally integrated, cold bridge is avoided, and the wall is light in weight, fireproof and self-insulating.

Description

A kind of lightweight fireproof insulating body of wall

Technical field

The present invention relates to a kind of construction wall, particularly a kind of lightweight fireproof insulating body of wall.

Background technology

Construction wall is the important component part of building, it play going along with sb. to guard him of External Wall and be incubated, lattice effect to interior wall, its body of wall must meet thermal insulation, sound insulation cuts off, the requirement of fire prevention lattice, light firm, and the quality of body of wall is directly connected to using function and construction quality and building energy conservation.

Along with building energy conservation Integration Strategy is implemented, the main body of building energy conservation is the floor in building level direction and the body of wall of vertical direction; Floor the present inventor of horizontal direction has write " a kind of hollow floor slab with small dense ribs ZL200410082381.9 "; " the lightweight member ZL200810192976.8 for cast-in-situ open-web floor "; " a kind of hollow floor system ZL201110332999.6 adopting reinforced bar foam combination filling component to make "; Technology such as " a kind of cast-in-situ hollow building roof pore-forming steel reticulate body and organic object group frame ZL201420220817.5 " solves the floor power saving of horizontal direction; The body of wall of vertical direction, at present, generally adopts GRC light partition wall body, aerated concrete building block to be used as infilled wall, to form combined partition, hollow concrete block, non-burning brick more with calcium silicate board with microporous as fluid concrete in partition wall clamping plate; And for example steel-mesh separation wall CN 102251604 A, the mesh sheet that have employed more than by constructional column and a slice or a slice is formed, and is connected between mesh sheet by constructional column, and steel mesh face and framework form mesh sheet, constructional column, fixes with keeper between mesh sheet and mesh sheet; Have foam concrete etc. in the middle of the mesh sheet, the mesh sheet adopted in scheme by with steel bar mesh welding machine by reinforcement fabrication mesh sheet; These schemes all exist that intensity is lower, deadweight is comparatively large, add the deadweight of agent structure, globality difference is unfavorable for structural seismic; Though a kind of steel-mesh separation wall solves GRC light partition wall body, aerated concrete building block is used as infilled wall Problems existing, also have that complicated construction technique, claim for eot, cost are too high, the defect of poor thermal insulation property; When Sandwich materials adopts organic material polyurethane foam, during polystyrene foam, fireproof performance and structural performance poor; When Sandwich materials adopts inorganic material gas concrete or fibrous concrete or concrete, structural weight per square meter increases; Again due in a kind of steel-mesh separation wall CN 102251604A, common welding steel mesh, do not possess take up carry a concrete function, need first with pulp shooting machine to integral wall whitewashing, whitewash floating, through at least 4 to 5 days after dry, then with slurry filling machine foam concrete injected mesh sheet hollow in; One deck insulating layer of external wall is added especially for also needing during exterior wall.Therefore, it is multi-functional integrated with building energy conservation that research and development one can meet building, realizes the breakthrough of cast-in-place light fireproof heat-preserving wall new technology, become the urgent need of construction wall field lightweight fireproof insulating wall technology innovation.

Summary of the invention

The object of the present invention is to provide a kind of brand-new cast-in-place light fireproof heat-preserving wall new technology, adopt steel reticulate body as the deck of lightweight fireproof insulating body of wall two sides and wall interior panel, utilize the netted physical efficiency of steel to take up and carry the specific function that do not leak outside of inorganic foamed slurry, realize the disposable cast-in-site of inorganic foamed slurry, optimize existing body of wall manufacturing technology; Reach and have that structural strength is higher, from heavy and light, good integrity, construction technology is simple, the duration shortens, reduce the good lightweight fireproof insulating body of wall of cost, self-heat conserving and fireproof performance; Meet building energy conservation requirement, particularly there is exterior wall fireproof and self-heat conserving performance, release is added insulating layer of external wall and is brought security risk and reduce cost of investment, is of value to and realizes building energy conservation integration realization, overcome the defect that existing cast-in-situ wall wall interior panel can not do deck simultaneously.
