Abstract
The invention discloses a cast-in-concrete hollow floor inner die system with an indoor smoke discharging function. The cast-in-concrete hollow floor inner die system comprises a core die built in concrete; at least one part of the core die is provided with hollow cavity core dies; the hollow cavity core dies are formed into a smoke discharging cavity system with an indoor smoke discharging function via connections of core die connection devices; one end of two ends of each hollow cavity core die forming the smoke discharging cavity system is provided with a connection port connected with the core die connection device; and the smoke discharging cavity system is provided with a smoke absorbing port and smoke discharging ports. House space utilization rate can be improved; influence of arrangements of the smoke discharging pipeline system to the house can be eliminated; house cost can be lowered; and the cast-in-concrete hollow floor inner die system with the indoor smoke discharging function can be widely applied to house construction.
Description
Technical field
The invention belongs to technical field of civil engineering, be specifically related to a kind of cast-in-place concrete hollow floor system inner system with indoor smoke discharging function.
Background technology
At present, cast-in-place concrete hollow building roof structure is more and more widely used in building construction, its inside is because putting the core of a large amount of band cavitys and there is a cavity layer, and this cast-in-situ hollow building roof is general thicker, its cavity layer is also thicker, but this cavity layer exists as just the horizontal force component in house, do not have profit he use.And the general pipe-line system also having various function in house, the pipe-line system of such as smoke evacuation, air-conditioning, fire-fighting, heating, smoke evacuation, water supply and drainage and other functions, this kind of pipe-line system is generally arranged in bottom or the top of floor, occupy the very large interior space, reduce the space utilization rate in house, and these pipe-line systems are crisscross, difficult arrangement and affect attractive in appearance, in order to the impact eliminating aesthetic must carry out ceiling decoration to house, add the cost in house undoubtedly.In addition these pipe-line systems expose easily by corrosion, also easily damaged.
In sum, the various function pipe-line systems in house occupy very large space and have drawbacks such as affecting attractive in appearance and easy damage on the one hand, and on the other hand, certain thickness hollow building cover exists again a large amount of void space be not utilized.If both organically can be combined, make the inner formwork system in cast-in-place concrete hollow building roof have indoor smoke discharging function, good technical economic benefit will be brought.
Summary of the invention
The object of the invention is for present cast-in-situ hollow building roof on an empty stomach layer not to be utilized and smoke-exhaust pipeline system occupies the problem of a lot of interior spaces, provide and a kind ofly can eliminate the hollow building cover inner formwork system of smoke-exhaust pipeline system on floor space and impact attractive in appearance.
The technical solution adopted for the present invention to solve the technical problems is: a kind of cast-in-place concrete hollow building roof with smoke discharging function, comprise the core be built in concrete, described core has a part at least for hollow cavity core, it is characterized in that, described hollow cavity core connects to form the smoke evacuation cavity system with indoor smoke discharging function by core linkage, the one or both ends of the described hollow cavity core for forming smoke evacuation cavity system have the connector be connected with core linkage, and smoke evacuation cavity system is provided with smoking port and smoke vent opening.
As the improvement of technique scheme, be provided with valve at described core linkage place.
Improve as another of technique scheme, the shape of the endoporus cross section of described hollow cavity core be circular or ellipse or rectangle or polygon.
As the another improvement of technique scheme, described hollow cavity core by parallel or serial or parallel connection with connect and connected mode form cavity system of discharging fume.
As the another improvement of technique scheme, at described smoking port or smoke vent opening, fume extractor is installed.
The invention has the beneficial effects as follows: because hollow cavity core of the present invention is not only as the horizontal force component of house superstructure, simultaneously also connect to form the smoke evacuation cavity system with indoor smoke discharging function by core linkage and be present in hollow building cover, not only increase the space utilization rate in house, and eliminate aesthetic effects that smoke-exhaust pipeline system layout brings at top, room and prevent smoke-exhaust pipeline system to expose easy damaged phenomenon and occur.

Below in conjunction with drawings and Examples, the present invention is described in further detail.
Embodiment 1:
See Fig. 1, Fig. 2, the cast-in-place concrete hollow floor system inner system with indoor smoke discharging function in the present embodiment, comprise the core 1 be built in concrete 8, have a part in core 1 at least for hollow cavity core 2, hollow cavity core 2 connects to form the smoke evacuation cavity system with indoor smoke discharging function by core linkage 3.One or both ends for this hollow cavity core 2 forming smoke evacuation cavity system have the connector 21 be connected with core linkage 3, and this smoke evacuation cavity system is provided with smoking port 4 and smoke vent opening 5, installs fume extractor 6 at smoking port 4 or smoke vent opening 5.The shape of the endoporus cross section of hollow cavity core 2 is circular, as shown in Figure 3 and Figure 4, also can be oval or rectangle or polygon.Hollow cavity core 2 couples together the connected mode of composition smoke evacuation cavity system by core linkage 3 serial or parallel connection, can also be that series and parallel connections uses simultaneously.
Embodiment 2:
See Fig. 1, Fig. 2, the present embodiment to have in the cast-in-place concrete hollow floor system inner system fundamental sum embodiment 1 of indoor smoke discharging function similar, difference is, at core linkage 3, place is also provided with valve 7, valve 7 can be dish valve or gate valve, can be used for preventing fires, controlling smoke evacuation trend.
Although describe embodiments of the present invention by reference to the accompanying drawings above, those skilled in the art can make various distortion or amendment within the scope of the appended claims.
