Abstract
The utility model discloses a hollow superstructure centre form system of cast in situ concrete with indoor ventilation function, place the mandrel of concrete in including in, the mandrel has partly hollow cavity mandrel that is at least, hollow cavity mandrel connects to form ventilation cavity system through mandrel connecting device, a connector, ventilation cavity system is equipped with air intake and air outlet for forming the one end of the hollow cavity mandrel of ventilation cavity system or both ends have to be connected with mandrel connecting device. the utility model has the characteristics of the improvement building space rate of utilization, elimination ventilation pipe -line system 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 floor system inner system with room ventilation 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 room ventilation 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 air pipeline system occupies a lot of interior spaces, it is provided that a kind of can eliminate the air pipeline system hollow building cover inner formwork system 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 ventilation function, including the core being built in concrete, described core is at least part of for hollow cavity core, described hollow cavity core connects to form ventilation cavity system by core connecting device, the one or both ends of the described hollow cavity core for forming ventilation cavity system have the connector being connected with core connecting device, and ventilation cavity system is provided with air inlet and air outlet.
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 ventilation cavity system.
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 room ventilation 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 air pipeline system and be arranged in the aesthetic effects brought at top, room and prevent air 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, Fig. 2, the cast-in-place concrete hollow floor system inner system with room ventilation function in the present embodiment, it is built-in with core 1 including being built in concrete 8, in core 1 at least part of for hollow cavity core 2, hollow cavity core 2 connects to form the ventilation cavity system with room ventilation function by core connecting device 3, one or both ends for forming this hollow cavity core 2 of ventilation cavity system have the connector 21 being connected with core connecting device 3, this ventilation cavity system is provided with air inlet 4 and air outlet 5, at air inlet 4 and air outlet 5, ventilation installation 6 is installed.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 ventilation 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 in the cast-in-place concrete hollow floor system inner system with room ventilation function of the present embodiment, difference is in that, it is also provided with control valve 7 at core connecting device 3 place, control valve 7 can be dish valve or gate valve, it is also possible to is other kinds of valve.
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.
