Description
Technical field
The present invention relates to prefabricated assembled concrete structural construction field, be specially regeneration concrete Prefabricated stacking floor and
The structure and production method of regeneration concrete two kinds of prefabricated board floors of full precast floor slab.
Background technology
It is also increasing to the demand of cement, sandstone now with the development of Building Trade in China, need to largely it cut into a mountain for quarrying
And digging sand, heavy damage ecological environment.Moreover, the high-quality natural aggregate in some areas of China has become withered in recent years
Exhaust, 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 substantial amounts of useless commerical ready-mixed concrete does not only take up the soil of preciousness, 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 the advantages that 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 reason, the present invention provides a kind of regeneration concrete precast floor slab structure
And production method.
The content of the invention
Purpose of the present invention proposition regeneration concrete precast floor slab structure and production method, including regeneration concrete are prefabricated folded
Floor and regeneration concrete two kinds of precast floor slabs of full precast floor slab are closed, realize the recycling of waste concrete, while meet assembled
The requirement of concrete structure, meets actual engineering design construction needs.
Technical scheme：
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 for setting longitudinal reinforcement, transverse steel 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
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 for setting in concrete layer longitudinal reinforcement, transverse steel to be formed, parallel uniform cloth is distinguished in both sides in regeneration concrete layer
Put negative reinforcement.
The regeneration concrete precast floor slab construction manufacturing method, during using recycled concrete superposed floor, it makes
Method is as follows：
(1) size of template is determined according to the size of recycled concrete superposed floor, first puts longitudinal reinforcement in template lining
And transverse steel, shearing and the pulling force arrangement precast concrete shearing resistance key block born then are needed according to shear key；
(2) regeneration concrete is poured, the height of prefabricated panel is the half of recycled concrete superposed plate height, to be regenerated mixed
Solidifying soil reaches form removal after expected intensity, and precast concrete shearing resistance key block protrudes from recycled concrete superposed floor prefabricated panel
Surface；
(3) after building site is by the recycled concrete superposed floor prefabricated panel positioning with precast concrete shearing resistance key block, so
Afterwards in two rows of negative reinforcements that are arranged in parallel above；
(4) self-compacting concrete is poured, after self-compacting concrete reaches expected intensity, the regeneration with shear key is obtained and mixes
Solidifying soil laminated floor slab, regeneration concrete layer are identical with self-compacting concrete layer height.
The regeneration concrete precast floor slab construction manufacturing method, during precast floor slab complete using regeneration concrete, it is made
It is as follows to make method：
(1) determine the size of template according to the size of recycled concrete superposed floor, first template lining put longitudinal reinforcement,
Transverse steel and negative reinforcement；
(2) regeneration concrete is first poured, regeneration concrete pours 3/4 that height is full prefabricated board height, will regenerate coagulation
Self-compacting concrete is poured after native vibration compacting again, the height of self-compacting concrete is the 1/4 of full prefabricated board height, to be regenerated mixed
Solidifying soil and self-compacting concrete reach form removal after expected intensity, obtain the full precast floor slab of regeneration concrete.
Advantages of the present invention and beneficial effect are：
1st, regeneration concrete precast floor slab structure and production method of the present invention, the prefabricated layer segment of Prefabricated stacking floor, then
The tensile region of the full precast floor slab of growing concrete and the less compressive region part that is stressed, are made of regeneration concrete, and are mixed
Solidifying Tulou 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,
So lower part uses 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 fills
The mechanical property advantage of respective material is waved in distribution, meets actual loading needs.
2nd, regeneration concrete precast floor slab structure and production method of the present invention because using regeneration concrete, its with it is non-again
Raw cast-in-place concrete floor is compared, and is economized on resources, environmental protection, is more met the development of green building.
3rd, regeneration concrete precast floor slab structure and production method of the present invention, it is same excellent with prefabricated concrete structure
The advantages that point, i.e., greatly reduce with wet construction amount, and on-site consolidation is simpler, and construction quality is easier to ensure that.
