Step is described in detail.According to following explanation and claims, advantages and features of the invention will become apparent from.It should be noted that, it is attached
Figure in the form of simplifying very much and uses non-accurately ratio, only real conveniently, lucidly to aid in illustrating the present invention
Apply the purpose of example.
The grandstand air-conditioning ground air-supply structure of one embodiment of the invention is described in detail with reference to Fig. 1 and Fig. 2.
Fig. 1 is the side view of the large stadium grandstand such as gymnasium or music hall, and Fig. 2 is the partial enlarged drawing in A portions in Fig. 1.
As shown in Fig. 2 grandstand includes that at least two-stage is stepped the step of shape overlap joint, every grade of step includes a vertical beam 1,
Panel 2 and inner liner layer (not shown), panel 2 are vertically installed in the top of vertical beam 1, and one end of panel 2 is along level
Direction extends a distance into, and the other end of panel 2 is vertical with the lower end of the vertical beam 1 in adjacent upper level step to be overlapped, panel 2
Outside be provided with inner liner layer, inner liner layer include external structure level course (not shown) connected vertically with it is outside
The vertical layer (not shown) of structure, the vertical layer of external structure be arranged at the side of one end of panel 2 and extend downward ground or
On panel 2 in adjacent next stage step, external structure level course is arranged at the upper surface of one end of panel 2 and horizontal-extending
To the vertical layer of external structure in adjacent upper level step, air chamber 5 that grandstand air-conditioning ground air-supply structure includes being sequentially communicated,
Some ventilation ducts 6, air groove 7 and some air outlets 8；Air chamber 5 is arranged at the lower section of grandstand, air chamber 5 by pipeline with
Air-conditioning main frame (not shown) is connected, some ventilation ducts 6 along the bearing of trend of grandstand be arranged at intervals at vertical beam 1 and/
Or in panel 2, vertical beam 1, panel 2, inner liner layer enclose to form air with the panel 2 in ground or adjacent next stage step
Groove 7, air outlet 8 are arranged in the vertical layer of external structure, and air outlet 8 is connected with air groove 7.
With continued reference to Fig. 2, generally, the large stadium such as stadiums or music hall, space are tall and big, and indoor occupant is concentrated, and
And when watching program, indoor closing is strict to criteria of noise control.The present embodiment to see that tableland air-supply structure disclosure satisfy that aforementioned
Require.Specifically, air-supply structure air-supply in tableland seen using the present embodiment, air-conditioner wind is first by the pipe of air-conditioning main frame
Road enters some air chambers 5, and as each air chamber 5 is connected with some ventilation ducts 6, thus air-conditioner wind flows through air chamber 5 and enters
Ventilation duct 6 forms tributary, and then the air-conditioner wind in each tributary is each passed through some ventilation ducts 6 and is all pooled to air groove 7, finally
The air-conditioner wind that Jing converges enters grandstand space outerpace by the air outlet 8 being correspondingly arranged with air groove 7, puts down so as to reach bleacher area
Slow stable air-supply effect.That is, in the grandstand of the stairstepping being made up of multi-stage stairs, being provided with per one-level step
One row stand seat, is provided with an air groove 7, the vertical layer of external structure of panel 2 in the corresponding one-level step for often arranging under-seat
Middle setting air outlet 8, air outlet 8 are connected with air groove 7.As each tributary air-conditioner wind is mixed by air groove 7, serve buffering and make
With so as to air-conditioner wind forms uniform temperature field and velocity field in bleacher area, without strong blowing feeling, and avoiding spectators' brain
After blow, reached comfortable air-supply effect.And, air-conditioner wind is from the vertical layer of external structure of the panel 2 positioned at step side
Air outlet 8 produce by boasting, be under seat bottom blow, air-conditioner wind is delivered to into gallery directly, the big sky of whole venue need not be undertaken
Between load, reduce the energy consumption of air-conditioning, improve air-supply efficiency.Additionally, carry out in the venues table tennis, shuttlecock,
When basketball, vollyball etc. are competed, all wind speed size is required.Using grandstand air-conditioning ground air supply mode, the wind speed of air outlet 8 all exists
In the wind speed range of regulation, various ball games are not affected, disclosure satisfy that environment of the various sports items to competition area
Require.Certainly, in order to save energy as far as possible, can be arranged using multisystem subregion and seen according to spectators in grandstand distribution situation
The air-conditioning in platform area.
With continued reference to Fig. 2, inner liner layer includes the intermediate layer 3 for setting gradually from inside to outside and decorative layer 4, positioned at outer
Intermediate layer 3 in the vertical layer of portion's structure extends downward the lower edge of panel 2, and the decorative layer 4 in the vertical layer of externally-located structure is to downward

In.Meanwhile, the decorative layer 4 positioned at the side surface of panel 2 is extended on the panel 2 in next stage step downwards.
With continued reference to Fig. 2, generally, according to the structure stress stability of the size and step at different levels of air quantity, determine logical
The number of airduct 6.Some ventilation ducts 6 are respectively independently disposed through in vertical beam 1 or in panel 2.The some of every grade of step are led to
Airduct 5 is connected with an air groove 7 being correspondingly arranged in this grade of step.Spectators' seat is arranged at the top of panel 2, and panel
2 is hanging near the side of air outlet 8, i.e., panel 2 only has one end stress, and the other end of panel 2 is ridden upon in vertical beam 1.Therefore
In order to meet 2 structure stress stability requirement of panel, the size of air groove 7 can select be：Width × a height of 300mm × 300mm,
Its length can be consistent with the length of step, or other can meet air quantity, wind speed and ledge structure stability feature and want
The appropriate length asked.
With continued reference to Fig. 2, especially, in order to preferably lift air-conditioner wind air-supply efficiency, air outlet 8 is shaped as wedge shape.
By the air outlet 8 for designing wedge shape, can cause the air-conditioner wind transmitted by air groove 7 from bottom to top air draft and produce turbulent flow, from
And the energy consumption of reduction air-conditioner wind, realize efficiently blowing.The size of air-supply is needed according to air force and unit interval, is gone out
Air port 8 is 15 ° -45 ° with the angle β of panel 2.
With continued reference to Fig. 2, in order to meet the sound-insulation noise requirement in large-scale place space, vertical beam 1 and panel 2 are near air groove
7 side is filled out and is provided with rock wool 9.
With continued reference to Fig. 2, further, grandstand air-conditioning ground air-supply structure also includes air outlet grid (not shown),
Air outlet grid is arranged at the one end of air outlet 8 away from air groove 7, so that the air-supply of air-conditioner wind ground is more stable, more gently,
More comforts are brought to spectators.
Continue with the construction method of the grandstand air-conditioning ground air-supply structure for describing the present invention with reference to Fig. 2 in detail.
