Description
First, technical field
The present invention relates to it is a kind of using filled out in framework of steel reinforcement foam heat-insulating board, it is outer spray stalk flyash pea gravel concreten it is new
The production method of type lightweight composite bearing wall.It is particularly suitable for low layer and tier building structural system.
2nd, background technology
Along with the development tide of China's architectural industrialization, according to the design requirement of green building, in order to realize building production
The energy conservation and environmental protection theory of industry improves the national development planning of the recyclable efficiency of resource.For construction wall, need to pass
The construction wall production mounting technique of system is combined with architectural industrialization development model, special according to the technology that architectural industrialization develops
Point integrates various walls production mounting techniques, and the pollution that so as to mitigate architecture construction when generates environment, is to realize to industrial or agricultural
The utilization once again of waste, turns waste into wealth.It explores and straw and flyash, blast-furnace cinder etc. is manufactured into novel light
Composite lead-bearing wallboard will be a kind of beneficial exploration.
At present, there are many solid-walled structure form type, and principal mode is as follows:
In concrete shear wall structure system, a large amount of cast-in-place concrete shear wall structures are cut for frame and shear wall system
In house, technology is more mature at present.It is with prefabricated or half prefabricated panel for assembly concrete shear wall structure
For main member, through assembled in situ, the cast-in-place concrete structure formed in part.Build guality is high, speed of production is fast, protection ring
Border economizes on resources, and is mainly used in tall building structures system.But presently, there are materials'use it is single, from it is great, can not return
It receives, node connection complexity causes difficulty of construction big, and poor reliability, and integrality performance of the structure is poor, is difficult to realize the technologies such as strong ties
Problem.
Steel plate shear force wall is assembled by Edge Enhancement component and interior steel plate of filling out, and is connected similar to the affixed vertical cantilever in bottom end
Beam.Vertical edges component is equivalent to the edge of a wing, and embedded steel plate is equivalent to web, and horizontal edge component then can Approximate Equivalent for laterally
Ribbed stiffener is a kind of cost-effective lateral support system, is mainly used in tall building structures system.The wall is because of dead weight
Gently, the burden to basis is reduced, reduces foundation cost.It is usually relatively thin using steel plate thickness in Practical Project, it saves
Use space;Program is industrialized by prefabrication, in-site installation etc., speed of application is substantially increased, saves operating expenses,
It is a kind of lateral resisting component of efficient and cost-effective.However, steel plate shear force wall is because unstability outside face usually occurs to early in thinner thickness,
Hysteretic loop " pinch " under reciprocating load is seriously, again not economical enough according to the larger steel plate of thickness.In addition, steel plate shears
Wall light plate is exposed, needs to take anti-corrosion, fire prevention measure, reduces structure durability.
The way of light gauge cold-formed steel shape combination load bearing wall generally use is (such as orientation plane by zinc-plated skeleton and light weight wall panel
Card, plasterboard, calcium silicate board) etc. pass through self-drilling connection.Although this bilateral hanging plate assembled wall have simple structure,
From heavy and light, compressive property is good many advantages, such as, but the heat preservation of the wall, sound insulation, fire prevention, shock resistance and hanging ability are poor,
Connection breaking causes the globality of wall relatively poor between the splicing of plug-in shingle nail and tapping screw, easy under horizontal outer load effect
The failure damage of tapping screw occurs.
Consider application problem present in more than panel wall system use, the premise of all wallboard advantages more than having
Under, in order to further improve the performances such as the heat preservation of load bearing wall, sound insulation, shock resistance and hanging ability, research and development are a kind of to use reinforcing bar
Foam heat-insulating board, outer spray stalk flyash pea gravel concreten novel light combination load bearing wall are filled out in skeleton, applied to low layer and more
In layer house structural system, there is important engineering significance.
3rd, invention content
The purpose of the invention is to comply with the development trend of architectural industrialization, construction wall construction technology process is reduced,
Site operation is allowed to become more simple and easy to do, meets the requirement of green building material, utilizes the materials such as agriculture and industry waste stalk flyash
Material, realization are turned waste into wealth, and a kind of use designed fills out foam heat-insulating board, outer spray stalk flyash microlith coagulation in framework of steel reinforcement
