Description

Band sleeper L shaped steel expanded metals composite mortar light hollow wall construction
Technical field
The present invention relates to be with sleeper L shaped steel expanded metals composite mortar light hollow wall construction, belong to a kind of novel energy-conserving, lightweight, insulation composite hollow body of wall.
Background technology
Along with the needs of social production development and people's life, the demand of dwelling house grows with each passing day, and one of which, masonry structure often are used as load-bearing or space enclosing structure.For this reason, the consumption of masonry is also in sharp increase.Loam brick once should be used as in the load-bearing or enclosed structure in the building widely.Loam brick exists that energy consumption is high, body of wall is big from great, poor seismic behavior, masonry project amount, cause energy consumption and environment pollution also very serious.Do not meet simultaneously China's STRATEGIES OF SUSTAINABLE DEVELOPMENT yet.Protect the fields for implementing, the fundamental state policy of energy conservation and protection environment, country forbids the use of clay solid brick, adopts green, energy saving materials for wall and advocate.Its two, be in the main dwelling house system with little high level, adopt the more of frame-shear wall or shear wall structure.Tradition cast-in-place shear wall structure, the deadweight of body of wall, rigidity is big, ductility is poor, thermal insulation difference etc. can not satisfy the new demand of modern green, energy saving building to materials for wall.
The novel wall structure that expanded metal lath composite mortar light hollow is a kind of lightweight, high-strength, low energy consumption, anti-seismic performance is good; It has done bold innovation to materials for wall and building structure, and this novel hollow wall structure meets green low-carbon, the energy-saving and emission-reduction idea of development that China " 12 " planning outline (six) proposes fully.This hollow wall structure adopts polyphenyl plate to fill in the middle of being, can alleviate deadweight, reduces the rigidity of structure, increases structure ductility, and has good thermal and insulating performance.It has easy, the advantages such as making is simple, easy construction of drawing materials; And also have huge social benefit and environmental benefit at aspects such as energy-saving and emission-reduction.
Summary of the invention
The object of the invention is to provide a kind of and is mainly used in space enclosing structure or premium properties such as the load-carrying members collection is in light weight, intensity is high, overall performance is good, energy-saving heat preserving, sound insulation is good, anti-seismic performance is good, easy construction are the green of one, energy-conservation, thermal insulation composite mortar hollow wall; Particularly a kind of band sleeper L shaped steel expanded metals composite mortar light hollow wall construction is to solve present green, the energy saving building new demand problem to materials for wall.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is following:
A kind of band sleeper L shaped steel expanded metals composite mortar light hollow wall construction is characterized in that: comprise steel truss, expanded metal lath, composite mortar layer, polyphenyl plate, tension rib, dark beam, sleeper; Said expanded metal lath, composite mortar layer are set in turn in the steel truss outside, and said steel truss, expanded metal lath and composite mortar layer are formed the deck of hollow wall, are mainly used in space enclosing structure, load-carrying members; Said polyphenyl plate is installed between steel truss, the expanded metal lath, constitutes energy-conservation layer, main insulation, heat insulation, the deadening of rising; Be arranged at intervals with dark beam and the sleeper that becomes horizontal and vertical setting respectively in the said hollow wall structure, play its rigidity of adjustment, improve its ductility, improve the effect of its anti-seismic performance.Wherein, Said band sleeper L shaped steel expanded metals composite mortar light hollow structural corners place is provided with the sleeper in a L type cross section; All the other sleeper are rectangle, and said band sleeper L shaped steel expanded metals composite mortar light hollow structural corners intersection also is provided with the tension rib that is used for the body of wall splicing.
Further, said steel truss is to be welded to form by vertical Φ 4300 cold drawn wires, horizontal Φ 4300 cold drawn wires and vertical S type Φ 4150 cold drawn wires.
Further, said expanded metal lath adopts the standard expanded steel diamond mesh, and its thickness is 0.4mm~0.8mm, and mesh size is 8 * 16mm, 10 * 20mm or 20 * 25mm.
Further, said composite mortar layer is the high-performance composite mortar that fusion entringite type expansion agent, silicon ash, these super fine powder additives of flyash and fiber reinforced material form, and its thickness is 35mm~40mm.
Further, the thickness of said polyphenyl plate is 40mm~50mm.
Further, said tension rib is the cold drawn wire of diameter 4mm, and spacing is 300mm.
Further, the sectional dimension of said dark beam is 50 * 120mm~80 * 120mm, and spacing is 400~600mm.
Further, the sleeper in said L type cross section, its free extension in every limb edge of a wing and width be (0~120mm) * 120mm, all the other rectangle sleeper sectional dimensions are 50 * 120mm~80 * 120mm, spacing is 600~900mm.
The present invention has the following advantages:
1, use is flexible, compliance is strong.Have in light weight, premium properties such as intensity is high, overall performance good, energy-saving heat preserving, sound insulation, antidetonation, easy construction.Can be used as non-bearing wall bodies such as infilled wall, internal partition wall, exterior wall and roof panel.Also can be used as the bearing wall of dwelling house and the lightweight shear wall of framework.
2, environmental protection.Fill insulant material, as expanded polystyrene, foam gather that ammonia is cruel, expanded perlite, frog stone etc.; Also can adopt with the waste and scrap is main cheap heat insulating material, like the leftover bits and pieces of waste and old diffusing rock wool, mineral wool, foamed plastics, be mixed with the slag of aglite etc.And have advantages such as in light weight, insulation, sound insulation, easy construction.
3, composite material.The high-performance composite mortar that uses is the advanced composite material (ACM) that in ordinary mortar, mixes super fine powder additives such as entringite type expansion agent, silicon ash, flyash and fiber reinforced material formation.The high-performance composite mortar has characteristics such as good toughness, elongation per unit length is big, adhesive property is good.These two kinds of materials with different properties of high-performance composite mortar and steel mesh reinforcement play a different role in structure, and steel mesh reinforcement mainly plays humidification, and the composite mortar layer mainly plays protection and anchorage effect.Learn from other's strong points to offset one's weaknesses between the two, act synergistically, thereby improve the service behaviour of member.
4, good fire prevention, resistance to elevated temperatures.The high-performance composite mortar is a cementitious materials, is again protective materials, need not do overcoat in addition.Test shows that when the high-performance composite mortar reached 600 ℃ in temperature, its intensity reduction was not more than 30%.The high-performance composite mortar can be protected steel mesh reinforcement effectively under the high temperature, makes it continue to carry.
5, easy construction, cheap.Wall body structure is divided into factory process and the job site makes two parts.Gauze wire cloth body of wall by factory process transports the job site to, be spliced into required house wall at the scene after, the composite mortar with the regulation label is put on the surface again, accomplishes the making of house bearing wall.Also have cheap, construction is convenient, be easy to promote, construction quality advantages such as assurance easily.
Through accompanying drawing and embodiment the present invention program is done further detailed description below.
