Technical field
The present invention relates to a kind of building structural element and manufacture method thereof, particularly a kind of with expanded metal lath be fixed in form on the clod wash lattice configuration steel skeleton, combination type steel net frame and compound building unit and the manufacture method thereof of concrete.
Background technology
In recent years, the output of China's steel, cement, common brick and all high the occupying first place in the world of consumption.As everyone knows, steel concrete, particularly common brick when benefiting the society, also bring society serious resource calamity.China is based on development multilayer and high residential building, and every year, only dwelling house was with nearly 5,000 ten thousand tons of reinforcing bar, nearly 1.5 hundred million tons of cement, and thing followed clay common brick, the expensive source of construction formwork institute are huge.Carry out residence energy saving, economize on water, save land, become a urgent fundamental state policy; Improve the dwelling house performance simultaneously and become the state compulsion requirement, major measure develops " "four news" (new ideas " technology exactly, gets for loam brick, compulsory implement wall reform, residence energy saving, development housing industrialization.
The basic structure system of China's multilayer, high residential building is continued to use frame construction, shear wall structure and brick mix structure system based on reinforced concrete member and common brick for a long time.Though prefabricated units withdraw from successively, the prematurity still of instead of clay brick technology, brick mix structure only part is replaced by frame construction, this with regard to exist some problems as: consume template, artificial amount is big, it is poor be incubated, and globality is poor, pipe line arrangement installation difficulty etc.Small-size concrete hollow block only can substitute common brick, difficulty changes the person's character of laying bricks, simultaneously the shrinkage crack problem, build modulus problem, production and processing problem by laying bricks or stones, to repeat transportation problem etc. following, consumption is little (seeing YB9082-97 " steel reinforced concrete structure design discipline " for details, " small-size concrete hollow block tecnical regulations ") also.
Though and steel reinforced concrete, encased structures intensity are high, there are structure, node problems; Single, the difficult architectonical of usefulness, complex structure, purposes are limited; Also exist artificial amount big simultaneously, it is poor to be incubated, and pipe line arrangement is installed problems such as difficulty.
Architectural lay wire thinks that in theory direct fluid concrete can become the combined wall member.But architectural lay wire is a kind of flexible member, unsuitable heavy reinforcement; The lacing wire of folding hook causes concrete disintegration easily; Insulation surface layer " Three Cut Off's ", bonding is weak, heat bridge is many, easily hollowing, crack.So only be a kind of low intensive reinforced concrete wall.Self problem is many, act on limited, little to steel concrete itself influence, self more be difficult to promote.(see DB 21/1210 for details---2001 " architectural lay wire concrete structure tecnical regulationss ").
Cold-rolled forming section, it is a kind of lightweight section member that steel sheet is processed into through clod wash, as structural element C shaped steel, U shaped steel, Z-shape steel etc. are arranged generally, have the irreplaceable advantage of hot-rolled steel section: the cross section specification is abundant, light and handy flexibly, strength-weight ratio is high, combined and instant, economical and practical, construction facility etc., low layer even multi-storey building structure have been used for abroad, but mainly adopt dry type cladding panel close rib structure, anticorrosionly need zinc-plated surface layer, stable, fire prevention and rigidity must have plug-in maintenance panel combination perfect.At present at home, its manufacturing technology is ripe; But application technology is general only as the small members in the steel work, be used in roof purline, body of wall keel in a large number, also be used for some primary structure member and combined members, but in dwelling house, only do the keel and the finishing skeleton of combined partition, do not find the application study in multilayer, high residential building agent structure as yet.
Also have a kind of cold-rolled forming section in recent years abroad, be characterized on the web of common cold-rolled forming section, being furnished with continuous, the large-area hole that has flange with space lattice structure, have the intensity height, in light weight, handsome in appearance, be convenient to advantage such as threading; Its production technology is ripe, but application technology does not change as yet.
Summary of the invention
Purpose of the present invention is the shortcoming and defect part that exists in above-mentioned technology, and a kind of have durable, high-strength, quick assembling construction, combination type steel net frame and concrete composite block and manufacture method cheaply are provided.
For achieving the above object, the present invention adopts following technical scheme,
Combination type steel net frame of the present invention and concrete composite block comprise: clod wash lattice configuration steel, concrete, plural clod wash lattice configuration steel is fixed on the connector, form clod wash lattice configuration steel skeleton, at one side or the above fixation steel plate net of one side or the expanded metal lath composite insulation boards of the external surface of clod wash lattice configuration steel skeleton; When the fixation steel plate net, concrete be filled in the clod wash lattice configuration steel skeleton and the hole of expanded metal lath in; When fixation steel plate net composite insulation boards, concrete be filled in the clod wash lattice configuration steel skeleton and clod wash lattice configuration steel skeleton and expanded metal lath complex heat-preservation sheet separation in.
The manufacture method of combination type steel net frame of the present invention and concrete composite block, make according to the following steps:
A, preparation expanded metal lath or making expanded metal lath composite insulation boards;

The one side of the external surface of c, clod wash lattice configuration steel skeleton or one side above fixation steel plate net (3) or expanded metal lath composite insulation boards;
E, when fixation steel plate net on clod wash lattice configuration steel skeleton, concrete is filled in the clod wash lattice configuration steel skeleton and the hole of expanded metal lath in; When fixation steel plate net composite insulation boards on clod wash lattice configuration steel skeleton, concrete be filled in the clod wash lattice configuration steel skeleton and clod wash lattice configuration steel skeleton and expanded metal lath complex heat-preservation sheet separation in.
The combination type steel net frame of employing said structure and concrete composite block and reinforced concrete member essential distinction and advantage are:
The construction effect of steel is different with structural performance: reinforcing bar can not be done rigid backbone in the construction stage and bear working load and finalize the design, locate, and therefore brings construction formwork, artificial construction and complicated concrete construction process; Inside concrete be the linear tension of a kind of reinforcing bar, with the composite force material of concrete compression, and strict to concrete structural performance.The clod wash lattice configuration steel is a kind of reinforcing bar member in concrete, has the independent structures function when realizing typing, location, can independently bear working load; Operational phase, when independently bearing structural load also with the concrete composite force; Make its bulk strength, stable, rigidity greatly improve, also be combined into the composite component of more excellent performance, make that component strength is higher, rigidity is bigger, resistance type ability is stronger, the cross section is littler, weight is lighter with concrete; Aspect antidetonation and fire prevention, plate, beam are reaching the stressed limit and the fire endurance state can not cause unexpected fracture yet, have more security performance than general reinforced concrete structure such as floor, beam.
Concrete structure function is different with performance requirement: in the present invention; the main obturator that concrete structure function is, intensive aspect, attachment, firm body and protective; therefore become combination stressed body, also be unlikely to cause component damage even concrete takes place to destroy.Can be general concrete or light weight aggregate concrete or gas concrete or fly ash concrete or brickbat aggregate concrete etc., can adopt flexibly according to the structure needs.Concrete pouring type is more flexible, can pour into a mould, pour into or spray; Steel frame can be wrapped up fully, also can partly wrap up; Also can laminated pouring; Can pour into a mould synchronously with other concrete component, also can pour into a mould step by step, can one-shot forming, also can distribute and finish, grasp flexibly as required.
Component surface performance difference: reinforced concrete surface does not have reliably protecting, is easy to generate the crack and the surface comes off, and smooth surface, is difficult to carry out finish coat; Concrete surface of the present invention is a kind of and the composite cover template net, has resistance type, impact capacity securely, can reliably control concrete surface crack, increase adhesive power.

The essential distinction and the advantage of the present invention and architectural lay wire technology are: the combination type steel net frame among the present invention is a kind of rigid backbone, has independently construct function and structure function; After the template net is fixed on the rigid backbone, himself intensity and modification be littler; to concrete hoop, ooze that to consider effect more remarkable; simultaneously can more reliable formation concrete cover; make that the present invention is a kind of high-intensity, serial steel reinforced concrete structure member or insulation construction combined member, comprising: beam, plate, post, wall etc.And architectural lay wire is a flexible intermediate member, does not possess complete construction function and structure function, can only as low intensive reinforced concrete wall member.
When the present invention was added with insulation layer, the difference and the advantage of the present invention and existing heat preservation technology were: the integral heat insulation combined member that the present invention is a kind of suitability for industrialized production, form in the manufacture method process, insulation layer and deck are inlayed mutually; Existing heat preservation technology is remedial, the hand paste insulation of taking at the finished product member, after particularly main structural engineering is finished, and its technology, performance all have great defective.
The insulation layer of architectural lay wire is inboard and have to penetrate with the ∏ keel from the merit screw and fix at the template net, forms a large amount of heat bridges and has a strong impact on heat insulation effect; The insulation surface layer is connected weak with structure basic unit, when when template net external surface is plastered, mortar can't permeate template net formation hollowing, very easily tenesmus forms horizontal fracture under gravity.
The present invention can be widely used in agent structure members such as the floor, body of wall, post, beam of various housing constructions such as low layer, multilayer even high level or other building, structure or structure, insulation, the comprehensive member of maintenance; Also can be used as the building maintenance member; Can form building system, also can have building system of one's own with other member; Also can be used for engineering fields such as municipal administration, traffic, harbour.
Compared with prior art, the present invention has following meaning and advantage:
1, the present invention can standardized designs, batch production production, mechanized construction, can realize heat insulating work batch production, pipe engineering synchronization especially, structure, maintenance, insulation, pipeline construction are integrated; Simplify on-the-spot technology, reduce ancillary works, improve engineering efficient, guaranteed performance quality.
2, the present invention substitutes the various reinforced concrete members in the general housing construction structure, and can have building system of one's own.By substituting reinforcing bar, cancellation construction formwork, thereby the social calamity that can avoid construction formwork to bring; Have simultaneously intensity height, cross section little, in light weight, the more structure space of large span, height can be provided, fundamentally solve technology, technology and the performance issue of steel concrete.
3, the present invention can thoroughly replace various masonry components, thereby avoids the clay common brick to bring the resource calamity of society.
4, the present invention has avoided the basic performance deficiency of Steel section member, steel reinforced concrete member, can more give full play to shaped steel and concrete compound advantage, and can become serial structural element or insulation construction combined member, and comprise wall, plate, beam, post, roofing etc., use more extensive.
