Abstract
The invention discloses a kind of prefabricated stalk fibre concrete hollow board for concrete superposed floor, it is characterised in that：It include hollow bottom plate 1. with the flat rib in longitudinal direction 2.；Be further characterized in that 3. the two bottom sides of the hollow bottom plate of the prefabricated board 1. leave the edge of a wing, 4. bottom two ends are extended with beard muscle, the flat rib in longitudinal direction 2. between provided with lateral connection reinforcing bar 5.；It is further characterized in that 1. the hollow bottom plate of the prefabricated board uses thermal conductivity factor less than 0.3W/ (m k), intensity is more than 7.5Mpa stalk fibre concrete, and 2. the flat rib in longitudinal direction uses the stalk fibre concrete that intensity is more than 20Mpa.During construction, first by the prefabricated board described in several piece in beam（Or wall）It is upper to support, then by rear pouring concrete concrete folding layer by beam（Or wall）It is superimposed together to form the self-heat conserving reinforced concrete laminated floor slab of assembled integral with prefabricated board.The assembled integral superstructure being formed by stacking using this kind of prefabricated board, with from heavy and light, superposed surfaces are connected firmly, good integrity, insulation, anti-seismic performance is good, the features such as low cost, it is very suitable for the superstructure of many, high-rise reinforced concrete structural construction, market application foreground is wide.
Description
Technical field
The present invention relates to a kind of floor, and in particular to a kind of for the prefabricated compound of assembled integral reinforced concrete superposed floor
Stalk fibre concrete hollow board.
Background technology
Portion's professional standard is built as state lives《Prefabricated concrete structure technical regulation》JGJ1-2014 promulgation and reality
OK, the industrialization of building will be rapidly developed, wherein the reinforced concrete superposed floor of assembled integral, due to it combine it is cast-in-place
Monoblock type and both prefabricated assembled advantage, both save template, reduce engineering cost, can ensure again superstructure globality and
Shock resistance, is more and more applied in modern civil engineering.The strength administered simultaneously with Rural Plane Source Pollution is promoted,
The comprehensive utilization of tangerine bar turns into the emphasis development of agricultural industry project of country, and the exploitation of tangerine bar building materials not only contributes to national tangerine
Bar, which is prohibited, to be burnt, and improves air pollution environmental, while can also increase farmers' income, is saved resource, is realized the sustainable development of construction industry
Exhibition.Therefore, using the stalk renewable resource of China's abundant, new assembled integral stalk fibre concrete folding building is researched and developed
Lid has huge national strategy meaning and economic and social benefits.
The content of the invention
A kind of from heavy and light, good integrity it is an object of the invention to develop, insulation, construction are simple, low cost new
The prefabricated stalk fibre concrete hollow board of type, uses it as the bottom plate of assembled integral reinforced concrete superposed floor, then, pours folded after
Layer is closed by the beam of it and surrounding（Or wall）Overlapping is integral.
The technical scheme is that：A kind of pre- made composite fiber concrete hollow board is provided, it is by hollow bottom plate and upper side
Plate two parts are constituted；The bottom of hollow bottom plate is provided with reinforcing bar, and the edge of a wing is left in both sides；Upper panel is broken along its length in centre
Open form is provided with lateral connection reinforcing bar into flat groove in flat groove.
Conduct oneself with dignity for reduction and be easy to the bottom plate in production, the prefabricated board to use circular hole hollow-core construction, there is a row to pass through thereon
Logical circular hole.
To meet the self-heat-preservation energy-saving effect of floor, the hollow bottom plate of the prefabricated board uses thermal conductivity factor and is less than
0.3W/ (m2 k), intensity is more than 7.5Mpa stalk fibre concrete.
The stalk that intensity is more than 20Mpa is used to improve the panel in the bearing capacity of construction stage, the prefabricated board
Fiber concrete.
During construction, first by the prefabricated board described in several piece in beam（Or wall）It is upper to support, it is then folded by rear pouring concrete concrete
Layer is closed by beam（Or wall）It is superimposed together to form the self-heat conserving reinforced concrete laminated floor slab of assembled integral with prefabricated board.
Due to the prefabricated stalk fibre concrete hollow board of the present invention, the lighter stalk fibre concrete of unit weight and hollow structure are employed
Appearance formula, realizes building energy conservation-structure-integrated, that is, reduces the consumption of concrete, reduce deadweight, the height of plate is increased again
Degree, improves the rigidity and bearing capacity of prefabricated board and laminated floor slab, meanwhile, the both sides of plate, which are left in the edge of a wing, the flat groove of plate face, to be provided with
Transverse steel, it is ensured that the overlapping of superposed surfaces is reliable.Therefore, the assembled integral superstructure being formed by stacking using this kind of prefabricated board,
With from heavy and light, superposed surfaces are connected firmly, good integrity, insulation, and anti-seismic performance is good, the features such as low cost, are especially suitable for
Yu Duo, high-rise reinforced concrete structural construction superstructure, market application foreground are wide.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the cross-sectional view of the present invention.
Embodiment
Such as Fig. 1 -- shown in Fig. 2, present embodiment discloses a kind of prefabricated composite stalk fiber concrete hollow board, it is by hollow-sole
Plate 1 and panel 2 are constituted；The bottom of hollow bottom plate 1 is provided with reinforcing bar 6, and the edge of a wing 4 is left in both sides, and upper panel 2 is in centre along length
Direction is disconnected forming flat groove 3, and lateral connection reinforcing bar 5 is provided with flat groove 3.
Conduct oneself with dignity for reduction and be easy to the bottom plate 1 in production, the prefabricated board to use circular hole hollow-core construction, thereon at equal intervals
It is provided with circular hole 7.
To meet the self-heat-preservation energy-saving effect of floor, the hollow bottom plate 1 of the prefabricated board uses thermal conductivity factor and is less than
0.3W/ (m2 k), intensity is more than 7.5Mpa stalk fibre concrete.
The stalk that intensity is more than 20Mpa is used to improve the panel 2 in the bearing capacity of construction stage, the prefabricated board
Fiber concrete.
When the present embodiment is manufactured, first the good bottom reinforcement bars 6 of tensioning on special production platform, then sets prefabricated board
Mould, first pour the stalk fibre concrete of hollow bottom plate 1, then lay transverse steel 5, lay the steel plate of flat groove 3, then pour
The stalk fibre concrete of panel 2, finally extracts flat channel plate, demoulding maintenance.During construction, first the prefabricated board described in several piece is existed
Beam（Or wall）It is upper to support, then by rear pouring concrete concrete folding layer by beam（Or wall）It is superimposed together to form dress with prefabricated board
Self-heat conserving reinforced concrete laminated floor slab with monoblock type.
