Background technology
It is also increasing to the demand of cement, sandstone now with the development of Building Trade in China, it need to largely cut into a mountain for quarrying
And digging sand, seriously destroy ecological environment.Moreover, the high-quality natural aggregate in some areas of China has become withered in recent years
It exhausts, the material used need to transport for long-distance from other places, not only increase the cost of building products, also aggravate the pollution of environment.It is same with this
When, the discharge capacity of waste material of buildings increasingly increases, and so a large amount of useless commerical ready-mixed concrete does not only take up valuable soil, and
Cause environment and social concern, the big city being particularly becoming tight in soil with Space Day is even more so.To a large amount of waste concretes
It is considered as the most effective measure for solving the problems, such as waste concrete to carry out recycling, that is, recycled concrete.Assembled
Concrete construction has many advantages, such as energy-saving and environmental protection, becomes one of the important directions of future architecture development.By regeneration concrete application
In assembled architecture, the effect killed two birds with one stone can be played.For this purpose, the utility model provides a kind of regeneration concrete precast floor slab
Structure.
Utility model content
The purpose of this utility model proposes regeneration concrete precast floor slab structure, including regeneration concrete Prefabricated stacking floor
Two kinds of precast floor slabs of precast floor slab complete with regeneration concrete, realize the recycling of waste concrete, while meet assembly concrete
The requirement of structure meets actual engineering design construction needs.
The technical solution of the utility model：
A kind of regeneration concrete precast floor slab structure, the structure are entirely pre- for recycled concrete superposed floor or regeneration concrete
Floor processed, wherein：
Recycled concrete superposed floor is folded up and down for self-compacting concrete layer and recycled concrete superposed floor prefabricated panel
Structure, the bar-mat reinforcement that longitudinal reinforcement, transverse steel is set to be formed in recycled concrete superposed floor prefabricated panel are closed, self-compaction mixes
Both sides are parallel respectively in solidifying soil layer is evenly arranged negative reinforcement, and self-compacting concrete layer and recycled concrete superposed floor are prefabricated
It is connected between bottom plate by the precast concrete shearing resistance key block being evenly arranged；
The full precast floor slab of regeneration concrete is regeneration concrete layer and self-compacting concrete layer iterative structure up and down, self-compaction
The bar-mat reinforcement that setting longitudinal reinforcement, transverse steel are formed in concrete layer, parallel uniform cloth is distinguished in both sides in regeneration concrete layer
Put negative reinforcement.
The advantages of the utility model and advantageous effect are：
1st, the utility model regeneration concrete precast floor slab structure, the prefabricated layer segment of Prefabricated stacking floor regenerate coagulation
The tensile region of native full precast floor slab and by the smaller compressive region part of pressure, is made of regeneration concrete, and concrete building
Plate mainly top in stress is under pressure lower part under tension, and the pressure that lower part is subject to mainly is undertaken by reinforcing bar, and institute is following
Portion is using the relatively low regeneration concrete of intensity, and the pressure that top is subject to has the more non-renewable concrete of intensity to undertake, and gives full play to
The mechanical property advantage of respective material, meets actual loading needs.
2nd, the utility model regeneration concrete precast floor slab structure, it is and non-renewable cast-in-place because using regeneration concrete
Concrete floor is compared, and is economized on resources, environmental protection, more meets the development of green building.
3rd, the utility model regeneration concrete precast floor slab structure equally has the advantages that prefabricated concrete structure, i.e.,
It is greatly reduced with wet construction amount, the advantages that on-site consolidation is simpler, and construction quality is easier to ensure that.

Specific embodiment
As shown in Fig. 1-Fig. 7, there are two types of structure types for the utility model regeneration concrete precast floor slab, respectively regenerate mixed
Solidifying soil laminated floor slab, the full precast floor slab of regeneration concrete.
(1) as Figure 1-Figure 5, recycled concrete superposed floor construction and production method are as follows：
(1) as shown in Fig. 2, determining the size of template 5 according to the size of recycled concrete superposed floor, first in template lining
Longitudinal reinforcement 2 and transverse steel 3 are put, the shearing and pulling force then born according to shear key needs arranges precast concrete shear key
Block 1 forms the structure of Fig. 2.
(2) regeneration concrete is poured on the basis of Fig. 2, the height of prefabricated panel is the one of recycled concrete superposed plate height
Half, concrete to be regenerated reaches form removal after expected intensity, and precast concrete shearing resistance key block 1 protrudes from recycled concrete superposed
The surface of floor prefabricated panel 8 forms Fig. 3 structures.
(3) after the recycled concrete superposed floor prefabricated panel 8 with precast concrete shearing resistance key block 1 is positioned in building site,
Then in two rows of negative reinforcements 4 that are arranged in parallel above, Fig. 4 structures are formed.
(4) self-compacting concrete is poured on the basis of Fig. 4, after self-compacting concrete reaches expected intensity, it is anti-to obtain band
The recycled concrete superposed floor 9 of key is cut, regeneration concrete layer 6 and 7 height of self-compacting concrete layer are identical.
(2) as Figure 6-Figure 7, the full precast floor slab structure of regeneration concrete and production method are as follows：
(1) as shown in fig. 6, determining the size of template 5 according to the size of recycled concrete superposed floor, first in template lining
Longitudinal reinforcement 2, transverse steel 3 and negative reinforcement are put, forms the structure of Fig. 6.
(2) regeneration concrete is first poured on the basis of Fig. 6, regeneration concrete pours 3/4 that height is full prefabricated board height,
Self-compacting concrete will be poured after regeneration concrete vibration compacting again, the height of self-compacting concrete is the 1/ of full prefabricated board height
4, concrete and self-compacting concrete to be regenerated reach form removal after expected intensity, obtain the full precast floor slab of regeneration concrete
10。
Embodiment the result shows that, the utility model have following features：1. regeneration concrete precast floor slab lower part is subject to
Pressure is mainly undertaken by reinforcing bar, so lower part is using the relatively low regeneration concrete of intensity, and the pressure that top is subject to have intensity compared with
High concrete undertakes, and gives full play to the mechanical property advantage of respective material, meets actual loading needs；2. using regeneration coagulation
Soil economizes on resources, environmental protection；3. precast slab uses steel template, make more environmentally friendly, conveniently；4. due to using half
Prefabricated and complete prefabricated mode, the wet construction amount at the scene of reducing save field fabrication template, energy conservation and environmental protection accords with green building
Demand for development, the utility model have very big popularization and application space.
