Description

A kind of prefabricated modular composite floor
The application is application number 201510697398.3, October 23 2015 applying date, a kind of denomination of invention " prefabricated molds The divisional application of block composite floor ".
Technical field
The present invention relates to Building technology, specifically a kind of prefabricated modular composite floor.
Background technology
Before one building housing construction, prefabricated a large amount of precast floor slab is needed, and there are many length of precast floor slab possibility The prefabricated quantity of floor of different specifications, each specification all can be very big, it is therefore desirable to expend a large amount of equipment and place is directed to Different specification floors carries out Prefabrication, and since distribution area is big, labour movement route is long, and the amount of labour accordingly increases, work Efficiency reduces, and cost is also high.
Invention content
Technical problem to be solved by the invention is to provide it is a kind of can be with can prefabricated different size in limited areal Prefabricated modular composite floor.
The prefabricated modular composite floor, it is characterised in that:Led to by the prefabricated end module of independent separate and intermediate module It crosses deformed bar and is combined as one block of precast floor slab, including polylith intermediate module and each one piece of end for being combined in precast floor slab both ends Module, the deformed bar passes through the reinforced hole of the longitudinally-aligned setting in middle part of end module and intermediate module, in end module Outer end applies prestressing force by anchorage, and the end module is consistent with the joint surface overall size of intermediate module.
Preferably, the end module and it is equipped with longitudinally disposed cavity with the middle part of intermediate module, in the end module End is equipped with the solid core end seat with bar-mat reinforcement.
The deformed bar is equipped with two rows, and two rows deformed bar point in end module and intermediate module Distribution is set, and position vertical non-alignment, quantity are equal.
Preferably, be transversely provided with pipeline hole in the middle part of the intermediate module and/or end module, for wear required water/ Tracheae and circuit.
Preferably, it being equipped with gas vent on the top of the reinforced hole, the air in duct is discharged when for being in the milk.
Further, the end module and intermediate module, which are arranged laterally at a spacing, is centered around on the outside of all deformed bars Rinforcement bar.
Further, the joint between the end module and the joint or intermediate module of intermediate module is equipped with mutual The tenon and slot of cooperation.
Further, the end module and intermediate module are vertically equipped with hole for hoist.
The present invention by precast floor slab be separated into module carry out it is prefabricated, due to the precast floor slab of different length size length with Identical modulus lengthens, therefore separated intermediate module can be and identical with single times or the long Prefabricated composite of modulus of integral multiple The size of the end module of width floor can be unified, therefore the precast floor slab of different length can be with the module of very few number specification It is combined after prefabricated.
The precedent for using precast floor slab separation Prefabricated composite is never had in industry technical staff, due to prefabricated Floor needs to bear floor load, and in the impression of people, the module of separation does not have the support of column or wall to be obviously difficult to To supporting role, and in the present invention program, show after the precompression of deformed bar by Force Calculation, floor is born Power has been more than traditional precast floor slab.And simultaneously because plant area needed for Prefabrication is significantly saved, to make into Originally be reduced, and manage and it is convenient for production, quality is easier to control.
Concrete perfusion plays etch-proof protective effect to deformed bar in reinforced hole, and deformed bar is made both to enhance The prestressing force tensile property of composite module, in turn ensures durability and reliability.Cavity in modular structure plays mitigation weight With the effect of heat-insulation and heat-preservation.

Specific implementation mode
Present invention will be further explained below with reference to the attached drawings and examples:As shown in Fig. 1~4, the prefabricated modular Composite floor is combined as one block of precast floor slab by the prefabricated end module 4 of independent separate and intermediate module 7 by deformed bar 6, Including polylith intermediate module 7 and each one piece of end module 4 for being combined in precast floor slab both ends, the end module 4 and intermediate module 7 Joint surface overall size is consistent, and for the floor of same width, end module 4 can be prefabricated into unified structure, intermediate die Block 7 could be provided as several different lengths based on same modulus as needed, cooperate into required length, with Reduce the quantity of intermediate module.The production of cooperation in this way, the precast floor slab of different length only needs several short lengths Place and the equipment made needed for precast floor slab is greatly saved in the combination of module, thus not only reduces cost, simultaneously It is resolved the problem of production capacity deficiency at place and insufficient funds.
By calculation shows that, the Prefabricated composite floor combined by deformed bar, bearing capacity is better than conventional Integral prefabricated floor.It was verified which can be applied directly in actual production completely.Its specific constructive embodiment For the end module and intermediate module are vertically equipped with hole for hoist 3.Hole for hoist is arranged in each piece of module, the block-by-block pair in construction Neat lifting, is then passed through deformed bar, applies prestressing force by anchorage.The deformed bar 6 passes through end module 4 and intermediate die The reinforced hole 10 of the longitudinally-aligned setting in middle part of block 7, and prestressing force is applied by anchorage 1 in the outer end of end module 4.It is being arranged When reinforced hole 10, big 10-15mm of diameter of aperture ratio deformed bar or so, when being tensed by anchorage 1, deformed bar is placed in the middle Setting is equipped with gas vent 12 on the top of the reinforced hole 10, is wrapped with filling concrete reinforced hole after tensing deformed bar The gas vent of deformed bar, the setting of reinforced hole top has reserved exhaust space.
As shown in Figure 1, the middle part of the intermediate module 7 and end module 4 is transversely provided with pipeline hole 5, it is required for wearing Pipeline, when being laterally laid with precast floor slab, pipeline hole alignment makes floor be integrated with the function of steel pipe buried in advance, facilitates subsequent construction.
Middle part such as Fig. 2,3, the end module 4 and with intermediate module 7 is equipped with longitudinally disposed cavity 8, and empty cavity can To insert thermal insulation material, while alleviating floor weight, thermal and insulating performance has been taken into account.
Such as Fig. 1, the solid core end seat 2 with bar-mat reinforcement 13 is equipped in the end of the end module 4.The end of end module is applying Stress is concentrated the most when prestressing force, therefore end needs to provide good stress basis.
Such as Fig. 2,4, the deformed bar is vertically equipped with two rows in end module and intermediate module, and that often arranges pre- answers Power reinforcing bar dispersed placement, makes prestressing force be uniformly applied to floor.Such as Fig. 3, the end module and intermediate module are arranged laterally at a spacing There is the rinforcement bar 11 being centered around on the outside of all deformed bars.
