Description
Technical field
The utility model relates to a kind of building construction member, particularly a kind of steel-bamboo combination reinforced concrete member.
Background technology
Steel concrete, since invention, has been widely used in the every field of building trade with its outstanding mechanical property, greatly promoted development and the change of builing industry, becomes the main constructional materials of modern architecture.Yet steel concrete need to consume a large amount of steel, this will cause the consumption of ample resources, the energy and ecological environment be caused to significant impact; In addition, the cost of steel is higher, also affects the use of the rural area that Liao Qi developing country and China's economy are comparatively backward.For this reason, people replace steel as stress frame with bamboo wood, form bamboo concrete.Bamboo wood has remarkable tensile property, in intensity, can substitute steel completely.Yet, because the modulus of elasticity of bamboo wood is less, only have 1/10th of steel, under service load effect, concrete can produce larger crack, bamboo reinforcement is exposed in air and affects its durability.
In fact, in the design load of using in structure design, the dead load that has comprised actual generation, mobile load and safety stock load thereof.In these loads, the dead load of only having actual generation is long-standing true load, and the ratio of shared total load little.Other load or not necessary being, or just accidentally occur.Thereby in reinforced concrete structure, most of tensile strength of reinforcing bar does not just really play a role as margin of safety within the most of the time in structure cycle in application life, thereby cause the waste of steel strength.And bamboo wood is except having the tensile strength that approaches steel, also there is the features such as expense is low, ecological, environmental protection.Thereby can consider to replace part reinforcing bar with bamboo wood, to resist this part non-long duration load and safety stock load, to reduce rolled steel dosage, to reduce cost.
Utility model content
The problem that the utility model exists for above-mentioned prior art is made improvement; be that technical problem to be solved in the utility model is to provide a kind of steel-bamboo combination reinforced concrete member; both can reduce rolled steel dosage, reduced cost, saved non-renewable resources, preserve the ecological environment; can increase again member and use rigidity; crack width while reducing normally to use, avoids bamboo reinforcement because corroding in exposure air.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of steel-bamboo combination reinforced concrete member, comprise stress frame and concrete, described stress frame is to be formed by reinforcing bar and bamboo reinforcement colligation in tensile region, described stress frame disturbing concrete after formwork.
Preferably, described reinforcing bar and bamboo reinforcement interval are arranged.
Preferably, the ring that staggers between described bamboo reinforcement is arranged.
Preferably, described bamboo reinforcement is round bamboo, bamboo cane or the bamboo rope that bamboo wood more than age was made by 4 years bamboos.
Preferably, the both sides of described bamboo cane offer respectively the groove that improves adhesion strength between bamboo reinforcement and concrete.
Preferably, described bamboo reinforcement surface impregnation or painting are brushed with the agglutination material bed of material that one deck has the functions such as anticorrosion, insect protected, fire prevention.
Preferably, the described agglutination material bed of material is heated bitumen, resin or fire resisting paint.
Preferably, described bamboo reinforcement surface glue is stained with the inorganic particle that improves adhesion strength between bamboo reinforcement and concrete.
Preferably, described bamboo reinforcement surface is wound with the iron wire that improves adhesion strength between bamboo reinforcement and concrete.
Preferably, described reinforcing bar and bamboo reinforcement are to be formed by stirrup colligation, and described stirrup adopts stirrup.
The utlity model has following beneficial effect: (1) is compared with steel concrete, utilize this natural resource that can rapid regeneration of bamboo wood, replace part reinforcing bar, reduced the consumption of non-renewable steel, play the effect that reduces building costs and preserve the ecological environment.(2) compare with bamboo concrete, overcome that bamboo concrete is out of shape greatly under service load effect, crack is wide, bamboo reinforcement is easily exposed to the medium shortcoming of air, durability is better than bamboo concrete.(3) be applicable to new farm building and townlet's median low structure, be conducive to promote Development of China's Urbanization, realize good economic benefit and environmental benefit.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
