Abstract
The invention discloses a cast-in-place concrete hollow floor frame having an indoor fire-fighting function. Core models are internally arranged in the hollow floor frame, and at least a part of the core models are hollow cavity core models; the hollow floor frame is provide with a smoke evacuation hollow cavity system having the indoor fire-fighting function, and a fire-fighting water supply and spraying pipeline system; the smoke evacuation hollow cavity system is formed by connecting hollow cavity core models through core model connection devices; one ends or two ends of the hollow cavity core models forming the smoke evacuation hollow cavity system are provide with a connection port connected to one core model connection device respectively; the smoke evacuation hollow cavity system is provided with an air inlet and an air outlet; the fire-fighting water supply and spraying pipeline system is formed by a fire fighting water supply pipe network and a spraying pipe network which are arranged in concrete or the core models. The cast-in-place concrete hollow floor frame has the advantages that: the use rate of a house space can be improved, the influence of fire fighting pipeline system arrangement on a house can be eliminated, and the house cost can be reduced; and the cast-in-place concrete hollow floor frame can be widely applied to house buildings.
Description
Technical field
The invention belongs to technical field of civil engineering, be specifically related to a kind of cast-in-place concrete hollow building roof with indoor fire-fighting 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 ventilation, 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, form the cast-in-place concrete hollow building roof with indoor fire-fighting 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 fire control smoke exhausting pipe-line system occupies the problem of a lot of interior spaces, provide and a kind ofly can eliminate the hollow building cover of fire control smoke exhausting pipe-line 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 indoor fire-fighting function, be built-in with core, described core has a part at least for hollow cavity core, also containing having the smoke evacuation cavity system of indoor fire-fighting function and fire fighting supply and spray piping in hollow building cover, described smoke evacuation cavity system is formed by connecting by core linkage by hollow cavity core, 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, smoke evacuation cavity system is provided with air intake and air outlet, described fire fighting supply and spray piping are made up of the fire water supply pipe network be arranged in concrete or in core and spray pipe network.
As the improvement of technique scheme, be provided with control 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 air-conditioning cavity system.
As the another improvement of technique scheme, in described air inlet, fume extractor is installed, at described air outlet, exhaust equipment 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, also be simultaneously be present in hollow building cover as the pipe-line system of fire control smoke exhausting, not only increase the space utilization rate in house, and eliminate fire control smoke exhausting pipe-line system and be arranged in the aesthetic effects that brings at top, room and prevent fire control smoke exhausting pipe-line system to expose easy damaged phenomenon and occur.
