Abstract
The utility model belongs to the field of steel structures, and particularly relates to a ventilated steel structure. The steel structure is of a hollow structure, a steel structure body is provided with a plurality of ventilation holes, and the air inlet end of the steel structure is provided with an opening-sealing air bag connected with an air pump. The ventilated steel structure does not need to be additionally provided with a ventilation device, the ventilation aim can be achieved through the steel structure, the structure is simple, the ventilated steel structure does not occupy other spaces, the size of an air port can be freely and linearly adjusted, and the ventilated steel structure is high in flexibility and convenient to use.
Description
Technical field
The utility model belongs to field of steel structure, is specially a kind of ventilation steel work.
Background technology
Due to the output of steel increase of China, and there is lot of advantages with industry and civilian construction facility that steel are built, for example: 1, steel building quality is light, and intensity is high, and span is large; 2, the steel building construction period short, corresponding reduction cost of investment; 3, steel building fire line is high, and anticorrosive property is strong; 4, steel building is moved conveniently, reclaims pollution-freely, and therefore increasing factory building mainly consists of the supporting member of steel work.Wherein the supporting member of steel work comprises steel column, girder steel, steel structure base, steel roof truss (span of factory building is larger certainly, has been all steel roof truss substantially now), steel roof system etc.
Deficiency in draught often in factory building, adds because production produces a large amount of high temperature and a large amount of oxygen consumption, makes workman's operating environment severe, even cause danger, so ventilating problem in assistant officer's factory building to be solved.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of ventilation steel work is provided, and improves the ventilation effect in factory building, and can regulate as required ventilate size or switching air port.
For realizing above-mentioned technical purpose, the scheme that the utility model provides is: a kind of ventilation steel work, and described steel work is hollow structure, offers some gravity vents on steel work body, and the air intake of steel work is provided for sealing air bag, and this sealing air bag is connected with air pump.
And described steel work is vertical support column, its air intake is to stretch out outdoor end.
And described steel work is horizontal crossbeam, its air intake is to stretch out outdoor end.
The utility model, without separately establishing ventilation installation, utilizes steel work itself to realize ventilation purpose, simple in structure, and without taking up room in addition, and freely linear adjustment air port is big or small, and flexibility ratio is high, is beneficial to practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the vertical support column of the utility model.
Fig. 2 is the structural representation of the horizontal crossbeam of the utility model.
Fig. 3 is the vertical support column of the utility model and horizontal crossbeam combination one.
Fig. 4 is the vertical support column of the utility model and horizontal crossbeam combination two.
Wherein, 1, steel work, 2, gravity vent, 3, sealing air bag, 4, air pump.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
The present embodiment provides a kind of ventilation steel work, and as shown in Fig. 1 ~ 4, described steel work 1 is hollow structure, offers some gravity vents 2 on steel work 1 body, and the air intake of steel work 1 is provided for sealing air bag 3, and this sealing air bag 3 is connected with air pump 4.
Further, as shown in Figure 1, above-mentioned steel work 1 is vertical support column, and its air intake is to stretch out outdoor end.
Further, as shown in Figure 2, above-mentioned steel work 1 is horizontal crossbeam, and its air intake is to stretch out outdoor end.
Further, the vertical support column of above-mentioned steel work 1 and horizontal crossbeam junction inner chamber communicate, as shown in Figure 3, outdoor end by vertical support column is blown, or, as shown in Figure 4, outdoor end by horizontal crossbeam is blown, or, together with the outdoor end of vertical support column and horizontal crossbeam, blow.
During use, only need to regulate by air pump 4 size of sealing air bag 3, control gap between sealing air bag 3 and steel work 1 air intake inwall (being air port size), to realize ventilation effect in various degree.As closed sealing, only sealing air bag 3 inflations fully need be contacted with steel work 1 air intake inwall.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvement or distortion, these improvement or distortion also should be considered as protection domain of the present utility model.
