Abstract
The invention relates to a composite structure of autoclaved aerated concrete and reinforced concrete and an application thereof. The prior precast slabs have large specific gravity, resulting in high weight of buildings and very high cost of foundations. The autoclaved aerated concrete has low specific gravity but poor strength, so as not to be used as supporting parts. The inventive product comprises a building concrete structure member (1) containing reinforced steel bars, wherein the low stress part at the middle of the concrete structure member uses autoclaved aerated concrete (2). The product can be used as precast elements for buildings, such as floor slabs and roof slabs, etc.
Description
Technical field:
The present invention relates to a kind of building slab of the light concrete that adopts steam pressurized mode and as the application of floor, roof panel.
Background technology:
Existing cast-in-place plate is the monolithic concrete structure, and proportion is bigger, causes the building body weight bigger than normal, and basic cost is too high.Gas concrete proportion is smaller, but its intensity is bad, can't use as load-supporting part separately.
Summary of the invention:
The purpose of this invention is to provide a kind of high strength precast plate of light body, this precast plate can reduce the building body weight, significantly reduces building costs.
Above-mentioned purpose realizes by following technical scheme:
Steam-pressing aero-concrete and reinforced concrete composite structure member, its composition comprises: have the build concrete structural element of stiffener, steam-pressing aero-concrete is adopted at the low stress position in the middle of the described member.
Described steam-pressing aero-concrete and reinforced concrete composite structure member, the member of described steam-pressing aero-concrete are cylindricality, and the side of described cylindricality has one group of keeper, has compression reinforcement in the described concrete component.
A kind of above-mentioned steam-pressing aero-concrete and reinforced concrete composite structure member are in the application aspect floor, roof panel, wallboard.
This technical scheme has following beneficial effect:
1. because the density of gas concrete is 1/5 of common conventional concrete, because the tension resistance to compression of the supporting member of building requires than higher, because in conjunction with bad, gas concrete can only be to use as nonload bearing element to the steam pressurized concrete traditionally in reinforcing bar.And on the structure, lower near the position stress of horizontal centre of form axle, gas concrete can meet the demands.The present invention adopts gas concrete to replace the ordinary concrete at the less position of intermediate stress of floor, roof panel equal strength member or wall body construction, can greatly alleviate the overall weight of building, alleviate foundation and lowrise stressor layer, reduce building costs, improve supporting capacity.
Among the present invention when adopting light material, steel concrete is still adopted at the main position of tension resistance to compression in former supporting capacity, and strengthens the reinforcing bar configuration at tension and resistance to compression position, under the prerequisite that reduces weight, guarantee the functional requirement of normal building structure, guarantee the safety of structure.Of the present invention rational in infrastructure, for building unit, for the last lower edge that member plays the gain and loss member of carrying effect, load part of the present invention still adopts steel concrete, and its security performance has the theoretical foundation of accurate mature and reliable.
3. China is raising new light material at present, reducing wall weight, improving the insulation degree, improve the sound insulation degree is important index, the present invention adopt add gas concrete mode as the floor between the different floors or/and wallboard, can significantly improve the insulating board heat-insulating property between each family of building body, this is for present interior temperature according to user's needs setting individual, guarantee that the heat of buying does not separately run off, and has significant technology progradation.
4. the steam pressurized concrete component adopts the prefabricated units mode, its condensation process and quality examination are finished in factory, can in time pick out problematic member, and can make the shape of various needs as requested, after directly install at the scene, pour into a mould floor and shear wall again, integral construction, speed is fast, and overall performance is good, anti-seismic performance is good, be fit to highrise building and use, adopt method of the present invention, quality can be guaranteed, and in construction site, reduced concrete wetting and watered workload, reduced dust pollution and noise pollution environment.
5. the present invention adopts ordinary concrete to combine the combined member made from gas concrete, not only have high strength, high resiliency, improved the intensity and the toughness of building unit, and since the prefabricated units rough surface porous of gas concrete can combine with concrete is effective, in cast-in-place process, can form the combining structure of inlaying mutually, bonding surface is Transfer of Shear effectively, collaborative work, and overall performance is good, have good seismic resistance, in use have good performance.
6. for the fixing position of gas concrete in cast-in-place plate, the side of aerocrete unit has one group of keeper, fixes at the theoretical position that calculates with gas concrete before guaranteeing cast.Certainly, for convenient transportation with avoid on-the-spot upset, keeper also can be not added on the prefabricated units of gas concrete, changes at the scene that the relevant position is provided with fixture into, and certain this operation is carried out under engineer's the guidance at the scene.
7. the present invention is by the combination of gas concrete and ordinary reinforced concrete, it is bigger to have solved the construction wall weight that exists for a long time, divide family heat preservation and soundproof degree problem of poor, overcome gas concrete and combined bad problem with reinforcing bar, corrected traditional prejudice that gas concrete can only use in nonload bearing element, realize the major reform of building building body material, had extensive market prospects.
Description of drawings:
Accompanying drawing 1 is that this product adopts steel concrete and steam-pressing aero-concrete combining structure schematic diagram.
Accompanying drawing 2 is employing steel concrete and the supercharging gas concrete combining structure schematic diagrames that have the cylinder filling.Fine rule top is pressure zone, can determine whether arrangement of reinforcement through calculating.The fine rule bottom is the tensile region, is the low stress area of steam-pressing aero-concrete work in the middle of two fine rules.
Among the figure:
The specific embodiment of the present invention:
Embodiment 1:
Steam-pressing aero-concrete and reinforced concrete composite structure member, its composition comprises: the build concrete structural element 1 that has stiffener 5, steam-pressing aero-concrete 2 is adopted at the low stress position of the close horizontal centre of form axle in the middle of the described member, and concrete width and shape can be determined by the label of common engineering calculation and gas concrete.
Embodiment 2:
In above-mentioned steam-pressing aero-concrete and the reinforced concrete composite structure member, the member of described steam-pressing aero-concrete is the prefabricated units 2 of cylindricality, as required one group of keeper 3 can be set in the side of described cylindricality, during site operation, guarantee the position of gas concrete prefabricated units in cast-in-place plate by keeper.In described concrete component, can also have tensile reinforcement 4 as required.By increasing the supporting capacity at steel reinforced carrying position, with gas concrete displacement non-bearing position ordinary concrete, thereby reduce the weight at non-bearing position, optimize wall performance thus
Embodiment 3:
A kind of above-mentioned steam-pressing aero-concrete and reinforced concrete composite structure member are in the application aspect floor, roof panel.
