Description
Technical field
It the utility model is related to a kind of floor, and in particular to a kind of for the prefabricated of assembled integral reinforced concrete superposed floor
Composite stalk fiber 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 it is prefabricated assembled both the advantages of, both save template, reduce engineering cost, can ensure again superstructure globality and
Shock resistance, more and more applied in modern civil engineering.The strength administered simultaneously with Rural Plane Source Pollution promotes,
The comprehensive utilization of stalk has turned into the emphasis development of agricultural industry project of country, and the exploitation of stalk building materials not only contributes to national straw
Stalk, which is prohibited, to be burnt, and improves air pollution environmental, while can also be increased farmers' income, and 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.
Utility model content
The purpose of this utility model is to develop one kind from heavy and light, good integrity, insulation, construction is simple, low cost
New prefabricated stalk fibre concrete hollow board, the bottom plate of assembled integral reinforced concrete superposed floor is used it as, then, by rear
Overlapping layers is poured by the beam of it and surrounding（Or wall）Overlap integral.
The technical solution of the utility model is to provide a kind of pre- made composite fiber concrete hollow board, and it is by hollow bottom plate and top
Panel two parts form；The bottom of hollow bottom plate is provided with reinforcing bar, and the edge of a wing is left in both sides；Upper panel it is middle along its length
Disconnection forms flat groove, and lateral connection reinforcing bar is provided with flat groove.
To reduce deadweight and being easy to produce, the bottom plate in the prefabricated board uses circular hole hollow-core construction, has 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 is less than using thermal conductivity factor
0.3W/ (m2k), intensity are more than 7.5Mpa stalk fibre concrete.
To improve the bearing capacity of construction stage, the panel in the prefabricated board is more than 20Mpa stalk using intensity
Fiber concrete.
During construction, first by the prefabricated board described in several piece in beam（Or wall）It is upper to support, 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 prefabricated stalk fibre concrete hollow board of the present utility model, the lighter stalk fibre concrete of unit weight and hollow is employed
Structural form, realize building energy conservation-structure-integrated, that is, reduce the dosage of concrete, reduce deadweight, increase plate again
Height, improve the rigidity and bearing capacity of prefabricated board and laminated floor slab, meanwhile, the edge of a wing is left in the both sides of plate, in the flat groove of plate face
Provided with transverse steel, it ensure that the overlapping of superposed surfaces is reliable.Therefore, the assembled integral building being formed by stacking using this kind of prefabricated board
Lid, have and be connected firmly from heavy and light, superposed surfaces, good integrity, insulation, anti-seismic performance is good, very suitable the features such as low cost
It is wide together in the superstructure of more, high-rise reinforced concrete structural construction, market application foreground.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is cross-sectional view of the present utility model.
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 form；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.
To reduce deadweight and being easy to produce, the bottom plate 1 in the prefabricated board uses 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 is less than using thermal conductivity factor
0.3W/ (m2k), intensity are more than 7.5Mpa stalk fibre concrete.
To improve the bearing capacity of construction stage, the panel 2 in the prefabricated board is more than 20Mpa stalk using intensity
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 extract 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.
