The utility model has the characteristics of improve the building space rate of utilization, eliminate fire service pipe way system layout to the influence in house, reduce building price etc, but the wide application is in housing construction.
Description
Technical field
This utility model belongs to technical field of civil engineering, is specifically related to a kind of cast-in-place concrete hollow floor system inner system 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, because having put the substantial amounts of cavity layer that exists with the core of cavity inside it, and this cast-in-situ hollow building roof is generally thicker, its cavity layer is also that comparison is thick, but this cavity layer exists as just the horizontal force component in house, it does not have profit he use.And the general pipe-line system also having various functions in house, the such as pipe-line system of ventilation, air-conditioning, fire-fighting, heating, smoke evacuation, water supply and drainage and other functions, this kind of pipe-line system is typically located at bottom or the top of floor, occupy the very big interior space, reduce the space utilization rate in house, and these pipe-line systems are crisscross, difficult arrangement and affect attractive in appearance, house must be carried out ceiling decoration by the impact in order to eliminate aesthetic, adds the cost in house undoubtedly.In addition these pipe-line systems expose easily by corrosion, also easily damaged.
In sum, on the one hand the various function pipe-line systems in house occupy very big space and to have impact attractive in appearance and the drawback such as be easily damaged, and on the other hand, certain thickness hollow building cover exists again a large amount of void space not being utilized.If can both organically be combined, the inner formwork system in cast-in-place concrete hollow building roof is made to have indoor fire-fighting function, it will to bring good technical economic benefit.
Summary of the invention
The purpose of this utility model is not to be utilized for present cast-in-situ hollow building roof on an empty stomach layer and problem that fire control smoke exhausting tubing occupies a lot of interior spaces, it is provided that a kind of can eliminate the fire control smoke exhausting tubing hollow building cover on floor space and impact attractive in appearance.
This utility model solves its technical problem and be the technical scheme is that a kind of cast-in-place concrete hollow floor system inner system with indoor fire-fighting function, including the core being built in concrete, described core is at least part of for hollow cavity core, smoke evacuation cavity system that described inner formwork system also includes having indoor fire-fighting function and fire fighting supply and spray piping, described smoke evacuation cavity system is to be formed by connecting by core connecting device by hollow cavity core, the one or both ends of the described hollow cavity core for forming smoke evacuation cavity system have the connector being connected with core connecting device, smoke evacuation cavity system is provided with air inlet and air outlet, described fire fighting supply and spray piping are made up of the fire water-supply pipe network being arranged in concrete or in core and spray pipe network.
As the improvement of technique scheme, it is provided with control valve at described core connecting device place.
As another improvement of technique scheme, generally circular in shape or the oval or rectangle of the endoporus cross section of described hollow cavity core or polygon.
As the another improvement of technique scheme, described hollow cavity core in parallel or serial or parallel connection with connect and connected mode composition 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 beneficial effects of the utility model are: owing to hollow cavity core of the present utility model serves not only as the horizontal force component of house superstructure, connect to form the smoke evacuation cavity system with indoor fire-fighting function simultaneously also by core connecting device and be present in hollow building cover, 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 brought at top, room and prevent fire control smoke exhausting pipe-line system to expose the generation of easy damaged phenomenon.
