Abstract
The utility model discloses a hollow superstructure of cast in situ concrete with indoor function of discharging fume, it has the mandrel to embed, the mandrel has partly hollow cavity mandrel that is at least, still contains the cavity system of discharging fume that has the indoor function of discharging fume in hollow superstructure, the cavity system of discharging fume is formed by connecting through mandrel connecting device hollow cavity mandrel, a connector, the cavity system of discharging fume is equipped with smoking mouth and exhaust port for forming the one end of the hollow cavity mandrel of the cavity system of discharging fume or both ends have to be connected with mandrel connecting device. the utility model has the characteristics of improve the building space rate of utilization, eliminate the pipe -line system that discharges fume and arrange 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 building roof 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, 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 smoke evacuation, 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 both organically can be combined, form the cast-in-place concrete hollow building roof with smoke discharging function, it will 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 smoke-exhaust pipeline system occupies a lot of interior spaces, it is provided that a kind of can eliminate the smoke-exhaust pipeline system 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 building roof with smoke discharging function, it is built-in with core, possibly together with the smoke evacuation cavity system with indoor smoke discharging function in hollow building cover, 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, and smoke evacuation cavity system is provided with smoking port and exhaust opening.
As the improvement of technique scheme, it is provided with 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 smoke evacuation cavity system.
As the another improvement of technique scheme, at described smoking port or exhaust opening, fume extractor 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, also it is that the pipe-line system as house smoke evacuation is present in hollow building cover simultaneously, not only increase the space utilization rate in house, and eliminate smoke-exhaust pipeline system and be arranged in the aesthetic effects brought at top, room and prevent smoke-exhaust pipeline system to expose the generation of easy damaged phenomenon.

Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is described in further detail.
Embodiment 1:
Referring to Fig. 1, the cast-in-place concrete hollow building roof with indoor smoke discharging function in the present embodiment, being built-in with core 1 in concrete 8, core 1 is at least part of for hollow cavity core 2, possibly together with the smoke evacuation cavity system with indoor smoke discharging function in hollow building cover.As shown in Figure 2, this smoke evacuation cavity system is to be formed by connecting by core connecting device 3 by hollow cavity core 2, one or both ends for forming this hollow cavity core 2 of smoke evacuation cavity system have the connector 21 being connected with core connecting device 3, this smoke evacuation cavity system is provided with smoking port 4 and exhaust opening 5, installs fume extractor 6 at smoking port 4 or exhaust opening 5.The endoporus cross section of hollow cavity core 2 generally circular in shape, as shown in Figure 3 and Figure 4, it is also possible to be oval or rectangle or polygon.Hollow cavity core 2 couples together the connected mode of composition smoke evacuation cavity system by core connecting device 3 serial or parallel connection, it is also possible to be series connection and parallel connection uses simultaneously.
Embodiment 2:
Referring to Fig. 1, Fig. 2, similar in and embodiment 1 basic at the cast-in-place concrete hollow building roof with indoor smoke discharging function of the present embodiment, difference is in that, is also provided with valve 7 at core connecting device 3 place, valve 7 can be dish valve or gate valve, it is possible to is used for preventing fires, controlling smoke evacuation trend.
Although being described in conjunction with the accompanying embodiment of the present utility model above, but those skilled in the art can make various deformation or amendment within the scope of the appended claims.
