Abstract
The utility model discloses an interlayer plug-in connecting component (7) for an indoor composite vent pipeline. The inner caliber of the utility model can be inserted by a composite vent pipe (3), and the middle part of the inner wall is provided with a baffle plate (8) as big as the inner caliber; one end of the baffle plate (8) is provided with a hole (9) as big as the inner caliber of a major vent pipe (1) and corresponding to the major ventpipe (1). The plug-in connecting component has the advantages of easy installation, facility, few blockage in construction, nice tightness and favorable air circulation effect.
Description
The utility model relates to a kind of room ventilation pipeline of building.
The room ventilation pipeline of existing building normally adopts precast concrete primary and secondary air chimney, and each floor gap primary and secondary air chimney is with the cement mortar formation ventilating duct that links into an integrated entity.The primary and secondary air chimney is made of sub-air chimney and female air chimney of the parallel up/down perforation of two one, and sub-air chimney is used for each interlayer room air delivery pipe, and female air chimney is used for total delivery pipe of each floor air discharging.Each floor gap primary and secondary air chimney is with brick and cement mortar sealing, so that each interlayer air is not ganged up.In actual installation, need sub-air chimney one end is destroyed one, still concordant to guarantee with cement mortar sealing back primary and secondary air chimney with brick, guarantee the ventilating duct resistance to overturning.When destroying, the shape that forms usually is irregular, often seal is bad during sealing, and because operating personnel very easily fall into down the straton ventilation stack with brick and foreign material accidentally results in blockage, cause circulation of air to be obstructed, it is also bad with cement mortar binding seal to add each interlayer primary and secondary air chimney, so whole ventilating duct circulation of air effect is bad.
The purpose of this utility model is to provide a kind of easy for installation, flexible, is difficult for stopping up the indoor primary and secondary ventilating duct of good leak tightness.
The purpose of this utility model is achieved in that a kind of indoor primary and secondary ventilating duct of building, comprises the primary and secondary air chimney, and each interlayer primary and secondary air chimney is linked together by plug connector, constitutes complete ventilating duct.Plug connector is the pipeline section that bore just can inject the primary and secondary air chimney in a section, its inwall middle part have one with its interior consistent baffle plate of bore size, the corresponding female air chimney of one end of baffle plate has one and the interior bore hole of the same size of female air chimney, the corresponding sub-air chimney of the sub-air chimney of the primary and secondary air chimney between levels, hole on corresponding female air chimney of female air chimney and the corresponding baffle plate is inserted in the plug connector respectively, the place crosses at the middle part baffle plate, thereby constitutes complete ventilating duct.
The utility model has adopted the plug connector connection owing between the levels primary and secondary air chimney, thus easy for installation, flexible, good leak tightness, circulation of air is effective.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a primary and secondary air chimney stereogram in the indoor primary and secondary ventilating duct;
Fig. 2 is a plug connector stereogram in the indoor primary and secondary ventilating duct;
Fig. 3 is primary and secondary air chimney and a plug connector connection status sectional drawing in the indoor primary and secondary ventilating duct.
Describe in detail according to primary and secondary ventilating duct interlayer plug connector details and the working condition that the utility model proposes below in conjunction with Fig. 1-Fig. 3:
Each layer rigid plastics primary and secondary air chimney 3 is made of sub-air chimney 2 and the female air chimney 1 that the centre has stationary barrier 6 separations, and the top of sub-air chimney 2 is provided with a gravity vent 4, and dividing plate 6 upper ends between the primary and secondary air chimney are provided with an opening 5.Interlayer plug connector 7 is plastic conduits that bore just can inject primary and secondary air chimney 3 in a section, there are one and its interior bore baffle plate 8 of the same size in its inwall middle part, the corresponding female air chimney 1 of one end of baffle plate 8 has one and female air chimney 1 interior bore hole 9 of the same size, the sub-air chimney 2 corresponding sub-air chimneys 2 of the primary and secondary air chimney 3 between levels, female air chimney 1 corresponding female air chimney 1, and 7 li of plug connectors are inserted in the hole 9 on the corresponding baffle plate 8 respectively, 8 places cross at the middle part baffle plate, and by gluing being connected together on baffle plate 8 and plug connector 7 inwalls, thereby constitute complete ventilating duct.
Claims (1)
1, a kind of indoor primary and secondary ventilating duct of building, comprise each interlayer primary and secondary air chimney (3), it is characterized in that being formed by connecting with plug connector (7) between the female air chimney of each straton (3), plug connector (7) is the pipeline section that bore just can inject primary and secondary air chimney (3) in a section, there are one and its interior bore baffle plate of the same size (8) in its inwall middle part, and the corresponding female air chimney of an end of baffle plate (8) (1) has one and the interior bore of female air chimney (1) hole of the same size (9).
