Description

Waterproof precast concrete cigarette hood

Technical Field

The utility model belongs to the technical field of the construction, especially, waterproof precast concrete cigarette hood.

Background

The flue bears the smoke exhausting function of modern housing and the updating rhythm of local building products, and is also an important mark for scientific and technological progress and life improvement, and the hood as the end structure of the house flue is needed for history and practicality and also for building beauty. The cement cover plate type blast cap is a common blast cap structure, has been raised for a long time and continues to the present.

However, the hood of this structure has some problems: the cement cover plate type hood is poor in waterproof effect, rainwater is easy to fall into the air duct due to the open structure, the wind and rain resistance of the hood is extremely poor, and particularly in the case of high floors, the rainwater flows backward very easily, and normal smoke discharge of the air duct is affected.

SUMMERY OF THE UTILITY MODEL

The utility model provides a waterproof precast concrete cigarette hood to solve the above-mentioned problem that exists among the prior art.

The utility model provides a waterproof precast concrete cigarette wind cap, which comprises a cigarette wind cap body and a base, wherein the base is fixedly arranged at the bottom of the cigarette wind cap body; the air cap body is of a rectangular structure with a closed top, an air duct is vertically formed in the air cap body, exhaust channels are horizontally formed in four side end faces of the air cap body respectively, and the inner end portions of the four exhaust channels are communicated with the top of the air duct.

Further, the exhaust passage is of a frustum structure which is horizontally arranged, and the outer end part of the exhaust passage is larger than the inner end part of the exhaust passage.

Furthermore, a connecting plate is arranged at the bottom of the smoke cap body and fixedly arranged in a groove formed in the top end face of the base through a bolt; a first through hole is formed in the connecting plate and is positioned at the bottom of the air duct; and a second through hole is formed in the base and is positioned at the bottom of the first through hole.

The utility model has the advantages that:

1. in this waterproof precast concrete cigarette wind cap, the wind channel is built-in at cigarette wind cap originally internally, and the wind channel top is connected exhaust passage and is outwards discharged fume, and the exhaust passage that the level set up can play waterproof effect, avoids the rainwater directly to fall into the wind channel.

2. In this waterproof precast concrete cigarette hood, exhaust passage is the toper structure, and the rainwater falls and to follow the inclined plane and discharge in exhaust passage, has strengthened the water-proof effects of cigarette hood, avoids the rainwater to store up in exhaust passage.

3. The utility model discloses possess waterproof performance, can be applied to high floor, still can normally discharge fume at precipitation weather, the condition that the rainwater flows backward can not appear, avoids the rainwater to get into the wind channel influence and discharges fume.

In the figure, 1 is a smoke cap body, 2-position connecting plates, 3 is a base, 11 is an air duct, 12 is an exhaust channel, 21 is a first through hole, 31 is a second through hole, and 32 is a groove.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

The utility model provides a waterproof precast concrete smoke cap, as shown in figure 1, which comprises a smoke cap body 1 and a base 3, wherein the base 3 is fixedly arranged at the bottom of the smoke cap body 1; as shown in fig. 2 and 4, the hood body 1 is a rectangular structure with a closed top, an air duct 11 is vertically formed inside the hood body 1, exhaust passages 12 are horizontally formed on four side end surfaces of the hood body 1, and inner end portions of the four exhaust passages 12 are all connected with the top of the air duct 11 in a penetrating manner. The horizontal exhaust passage 12 can play a waterproof role, preventing rainwater from directly falling into the air duct 11. The exhaust passage 12 is a horizontally arranged frustum structure, and the outer end part is larger than the inner end part. Exhaust passage 12 adopts above-mentioned frustum structure, can further improve water-proof effects, and the rainwater that falls into exhaust passage 12 can follow the direct escape way of inclined plane, prevents effectively that exhaust passage 12 from the internal accumulation rainwater.

As shown in fig. 1 and 3, a connecting plate 2 is arranged at the bottom of the smoke cap body 1, the connecting plate 2 and the smoke cap are integrally cast, a plurality of threaded holes for installing bolts are formed in the connecting plate 2, the connecting plate 2 is fixedly arranged in a groove 32 formed in the top end face of the base 3 through bolts, and corresponding threaded holes are formed in the groove 32; a first through hole 21 is formed in the connecting plate 2, and the first through hole 21 is located at the bottom of the air duct 11; a second through hole 31 is formed in the base 3, and the second through hole 31 is located at the bottom of the first through hole 21. The first through hole 21, the second through hole 31 and the air duct 11 are connected to form a complete passage. During installation, the prefabricated base 3 is placed at the port position of the smoke exhaust pipeline, the base 3 is connected with a roof joint in a pouring mode, and after the base 3 is installed, the connecting plate 2 of the smoke exhaust pipeline 11 body is fixedly installed in the groove 32 in the top of the base 3 through bolts.

The utility model discloses possess waterproof performance, can be applied to high floor, still can normally discharge fume at precipitation weather, the condition that the rainwater was irritated backward can not appear, avoids the rainwater to get into the wind channel influence and discharges fume.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious changes and modifications can be made without departing from the scope of the invention.
