Abstract

The utility model relates to a precast roof ventilator. The utility model is mainly composed of a precast ventilating pipe and a ventilator, wherein, the precast ventilating pipe is a metallic tubular body which is erected at the floor slab position of the top floor of a factory building and is precast on a floor slab. The lower end of the ventilator is provided with a cover slab which covers on the top end of the precast ventilating pipe. Because the structure is provided and the precast ventilating pipe is inbuilt on the floor slab in advance and is combined at the position of a ventilating opening of the floor slab, the trouble of the brick push masonry of the ventilating pipe is exempted. The ventilator is conveniently and directly sheathed on the ventilating pipe, and the utility model avoids the installation trouble which is caused by the dimension which does not correspond.

Description

The precast type roof ventilator

The utility model relates to a kind of indoor ventilator unit, is a kind of precast type roof ventilator specifically.

Generally ventilate or dispel the heat bad factory building; ventilate and the heat radiation condition of poor for improving; usually can on roof or metope, ventilated port be set; and on ventilated port, install ventilator; and it is outer and can increase ventilation will the hot gas in the factory building to discharge factory by ventilator, thereby the be improved ventilation and the problem such as bad of dispelling the heat.

And the known mode of installing ventilator at the ventilated port of factory building, as shown in Figure 5, the floor a that lies in attic upward pushes away with fragment of brick and is built into the ventilation duct b that a brick is made, again installing one ventilator c on ventilation duct, so can the hot gas in the factory building be shed, to improve the situation of improper ventilation by ventilator.

So when the construction factory building, the ventilated port on the floor of attic must be piled into ventilation duct b with fragment of brick, can be used to install ventilator c, so comparatively bother inconvenience when construction; And if the ventilation duct b that brick is made is more attractive in appearance, can stick ceramic tile or nogging on its surface usually in appearance, so then can increase many construction costs and time.

Other has the mode construction ventilation duct b that irritates casting with concrete, is used to install ventilator c equally; But must build template before the construction, the side is used for irritating the casting concrete, so bother more in construction; And behind form removal, must whitewash leveling at its outer surface again, make ventilation duct b more attractive in appearance, if will make it that more beautiful outward appearance is arranged, then must be as previously mentioned, stick ceramic tile again in its surface or nogging is modified, like this then increase time of more construction cost and construction again.

Moreover, the size of its mouth of pipe of ventilation duct b made from concrete or brick can't as the mechanical dimension accurately, its error amount is quite big, if the mouth of pipe external diameter of ventilation duct b is bigger than the socket of ventilator c, then can't install ventilator c, otherwise if the ventilation duct b external diameter that ventilation duct b concrete or brick are made less than the socket of ventilator c, then can't firmly install ventilator, so must be repaired, the side is installed ventilator c again, thereby increases the trouble when installing.

This creator is thoughts on installing ventilator c on the ventilated port of factory building, must be in advance with concrete or fragment of brick construction ventilation duct b on floor, thus comparatively trouble inconvenience in construction, and to increase construction cost; And the mouth of pipe of the ventilation duct b that concrete or brick are made is inaccurate, and can't firmly install ventilator c and cause the installing ventilator inconvenience.A kind of precast type roof ventilator is designed in this creator thereby leadoff design eventually.

Main purpose of the present utility model aims to provide a kind of precast type roof ventilator system and is made up of precast type ventilation duct and ventilator, and this precast type ventilation duct stands on and defaults in Lou Xiangshang and exempt the trouble of piling up ventilation duct with fragment of brick.

Another purpose of the present utility model is then providing a kind of precast type roof ventilator, makes this ventilator get directly and is sleeved on the ventilation duct, so can avoid precast type ventilation duct and ventilator to cause installing to go up trouble because of size is not inconsistent.

The purpose of this utility model is to realize like this, a kind of precast type roof ventilator, include a ventilator and a ventilation duct, it is characterized in that this ventilation duct is to be made of a precast type ventilation duct, and the tubular body that this precast type ventilation tubing is a metallic material, uprightly place the floor location of factory building attic, and precasting is on floor; Described ventilator is located at the top of this precast type ventilation duct; The lower end of this ventilator has a cover plate again, and it must cover on the top that is contained in the precast type ventilation duct.

Effect of the present utility model is, because this precast type ventilation tubing is preset on the floor in advance, and be incorporated on the position of ventilated port of floor, thereby must exempt the trouble that pushes away the block ventilation duct with fragment of brick, and can be convenient to that ventilator is directly overlapped ventilator forms, and this precast type ventilation duct gets upright precasting on floor and must exempt with fragment of brick and push away the trouble of building ventilation duct, and can be convenient to ventilator directly is sleeved on the ventilation duct, causes installing to go up trouble to avoid size not to be inconsistent.

Fig. 5 is known three-dimensional exploded view.The simple declaration of piece number

Precast type ventilation duct 1

Ventilator 2

Cover plate 21

Floor 3

It is as follows to describe the utility model in detail below in conjunction with embodiment and accompanying drawing thereof;

At first, see also Fig. 1, the utility model is made up of precast type ventilation duct 1 and ventilator 2, and the tubular body that this precast type ventilation duct 1 is a metallic material, it gets floor 3 positions that uprightly place the factory building attic, and precasting is on floor 3; The lower end of this ventilator 2 has a cover plate 21 again, and it must cover on the top that is contained in precast type ventilation duct 1.

According to above-mentioned structure, because this precast type ventilation duct 1 is prior manufacturing moulding, during construction floor 3, only need to place desire to be provided with on the position of ventilated port precast type ventilation duct 1, it can be embedded on the floor in advance, and be combined on the position of ventilated port of floor 3, thereby must exempt pushing away and build or concrete is irritated the trouble of casting the shape ventilation duct with fragment of brick.

Moreover, because this precast type ventilation duct 1 and ventilator 2 are that prior manufacturing is finished, so the size of the cover plate 21 of the mouth of pipe of this precast type ventilation duct 1 and ventilator 2 can fully surely be closed, after making that floor 3 construction are finished, can directly ventilator 2 directly be sleeved on the mouth of pipe of precast type ventilation duct 1, therefore avoided size not to be inconsistent and cause installing to go up to bother.

In addition, the section configuration of this precast type ventilation duct 1 must be rectangular opening or circular port, selects for use and must do different the variation according to the needs of design, as Fig. 2, Fig. 4 and shown in Figure 5.
