Description
Technical field
The utility model is related to Building technology, specifically a kind of modular combination precast floor slab.
Background technology
, it is necessary to prefabricated substantial amounts of precast floor slab before one building housing construction, and the length of precast floor slab may have various
Different specifications, the prefabricated quantity of floor of each specification all can be very big, it is therefore desirable to expend substantial amounts of equipment and place is directed to
Different specification floors carry out Prefabrication, and because distribution area is big, labour movement route is long, and the amount of labour is accordingly increased, work
Efficiency reduction, cost is also high.
But if modular floor is tensed with prestressing force with many reinforcing bars only combined, its steel using amount will be significantly more than
Common process.
The content of the invention
Technical problem to be solved in the utility model is to provide one kind can be with can prefabricated different rule in limited areal
The modular combination precast floor slab of lattice, and steel using amount is saved as far as possible.

Specific embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples：As shown in Fig. 1~4, the modularization
Combination precast floor slab is combined as one piece of prefabricated building by the prefabricated end module 4 of independent separate and intermediate module 7 by deformed bar 6
Plate, including polylith intermediate module 7 and each one piece of end module 4 for being combined in precast floor slab two ends, the end module 4 and intermediate module
7 composition surface overall size is consistent, and for the floor of same width, end module 4 can be prefabricated into unified structure, middle
Module 7 could be arranged to several different lengths based on same modulus as needed, cooperate into required length,
To reduce the quantity of intermediate module.By such cooperation, the production of the precast floor slab of different length only needs several short lengths
Module combination, greatly save the place needed for making precast floor slab and equipment, thus not only reduce cost, together
When make production capacity not enough at place and insufficient funds problem be resolved.
Show by calculating, the Prefabricated composite floor combined by deformed bar, its bearing capacity is better than conventional
Integral prefabricated floor.It was verified which can be applied directly in actual production completely, and floor actually bears down
Curved pressure concentrates the bottom for acting on floor, therefore the reinforcing steel bar bear for only running through and being tensed by prestressing force in the bottom of floor comes
Prevent bending deformation under composite floor.
