Prefabricated concrete structure meets the resources conservation proposed in China " 12 " planning, eco-friendly social desirability, is one of effective way realizing building energy conservation reduction of discharging and housing industrialization.Reinforced concrete slab has can make component industrialization, manufacture and be not subject to seasonal restrictions, greatly shorten cycle and save the advantage such as a large amount of template and other resources.But prefabricated units overall performance, anti-seismic performance are poor compared to cast-in-place structural, laminated floor slab bearing capacity also the shortcoming such as relatively low be also exist actually.At present, the main development direction of reinforced concrete slab has two: on the one hand, and along with the worsening shortages of china natural resources, the problem that searching novel environment friendly, ecomaterial carry out engineering construction needs solution badly; On the other hand, improve the bearing capacity of reinforced concrete slab, overall performance and anti-seismic performance, making it can with cast-in-place structural close to exceeding even.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the object of the present invention is to provide a kind of steel fibre regeneration brick grain concrete list rib base plate laminated floor slab, the stressing conditions of superposed surfaces is optimized by the structural form changing prefabricated panel, improve the cooperative work performance of prefabricated panel and last layer, improve bearing capacity and the globality of laminated floor slab, solve the drawback of prefabricated units, the concrete that the present invention utilizes, steel fibre regeneration brick grain concrete is a kind of green material, regeneration brick grain is that screening is extracted from building waste, not only save material, environmental protection, wide material sources, and can help to process building waste, reach twice laid, the object of beautifying the environment.
To achieve these goals, the technical solution used in the present invention is:
A kind of steel fibre regeneration brick grain concrete list rib base plate laminated floor slab, comprise the steel fibre regeneration brick grain concrete prefabricated base plate 1 with single rib 11, the one side with single rib 11 on steel fibre regeneration brick grain concrete prefabricated base plate 1 has cast-in-situ concrete layer 2.
In described steel fibre regeneration brick grain concrete prefabricated base plate 1, containing steel fibre 78kg, cement 500kg, water 200kg, regeneration brick aggregate 1150kg and sand 500kg in every cubic meter of concrete.
In one side with single rib 11 on described steel fibre regeneration brick grain concrete prefabricated base plate 1, longitudinally plucking produces matsurface.
There is baseplate reinforcing bar mesh sheet 12 in described steel fibre regeneration brick grain concrete prefabricated base plate 1, in single rib 11, have longitudinal single rib arrangement of reinforcement 13 along its length.
Present invention also offers the manufacture method of described steel fibre regeneration brick grain concrete list rib base plate laminated floor slab, comprise the steps:
Step 1, the concrete preparation of steel fibre regeneration brick grain:
First steel fibre is made to be dispersed in regeneration brick grain steel fibre and regeneration brick grain mix and blend; Sand and cement are mixed with the mixture of steel fibre and regeneration brick grain, first dry stirring adds water stirring more again; Mixing time is consistent with ordinary concrete; Finally obtained steel fibre regeneration brick grain concrete.
Step 2, the preparation of prefabricated panel:
First make the wooden form of prefabricated panel, and the single rib template on base plate also makes in the lump, colligation baseplate reinforcing bar mesh sheet 12 and single rib arrangement of reinforcement 13; Then use the concreting of steel fibre regeneration brick grain, prefabricated panel begins to take shape; After base plate upper strata is floating, longitudinally plucking produces matsurface; Last standard curing 14d, stripping, forms the steel fibre regeneration brick grain concrete prefabricated base plate 1 with single rib 11;
Step 3, cast-in-situ concrete layer is built:
When prefabricated panel intensity reaches more than 75% of design load, first wetting backplate surface, installs template; Then cast-in-situ concrete layer reinforced mesh 21 is laid, concreting, after floating, standard curing 28 days.
Compared with prior art, the invention has the beneficial effects as follows:
1, laminated floor slab of the present invention uses novel ecological concrete material, effectively can alleviate traditional raw-material consumption problem, economize on resources, and also solves the problem that urban building waste re-uses simultaneously, has the advantage such as energy-conserving and environment-protective, green ecological.
2, laminated floor slab of the present invention is compared with the common precast floor slab of tradition, and have good integrity, anti-seismic performance is superior, from heavy and light and there are the advantages such as stronger bonding and shearing ability.
3, laminated floor slab of the present invention can carry out industrialization Production line, makes industrialization of construction industry, automation, economizes on resources, and improves traditional architecture production environment, improves architecture production efficiency.
Accompanying drawing explanation
Fig. 1 is organigram of the present invention.
Fig. 2 is finished product schematic diagram of the present invention.
Detailed description of the invention
Embodiments of the present invention are described in detail below in conjunction with drawings and Examples.
As depicted in figs. 1 and 2; a kind of steel fibre regeneration brick grain concrete list rib base plate laminated floor slab; comprise the steel fibre regeneration brick grain concrete prefabricated base plate 1 with single rib 11; one side with single rib 11 on steel fibre regeneration brick grain concrete prefabricated base plate 1 has cast-in-situ concrete layer 2, forms the state of occlusion.
Steel fibre regeneration brick grain concrete prefabricated base plate 1 of the present invention adopts steel fibre regeneration brick grain concrete, and steel fibre regeneration brick grain concrete is a kind of novel ecological material, the features such as lightweight, thermal insulation, refractoriness are good, good corrosion resistance, anti-seismic performance are good that it has.The concrete proportioning of steel fibre regeneration brick is:
