Abstract
The invention relates to the field of constructional engineering, in particular to an efficient silent air duct well structure for a roof. According to the technical scheme, an expansion ventilation cavity is formed in the periphery of a prefabricated heating and ventilation air duct well; perforated ventilation aluminum plates are arranged on the four peripheral walls and the top of the expansion ventilation cavity; an aluminum plate top cover is arranged over the prefabricated heating and ventilation air duct well, and the elevation of the aluminum plate top cover is the same as that of the perforated ventilation aluminum plates; a rain shelter concrete overturned opening is arranged abutting against the part, with the prefabricated heating and ventilation air duct well, of the roof; an outward roof drainage slope within the range of the expansion ventilation cavity; a drainage floor drain is arranged at the indoor bottom of the part, with the prefabricated heating and ventilation air duct well, of a building. According to the efficient silent air duct well structure for the roof, the actual air inlet quantity and air exhaust quantity of the roof air duct well are effectively increased, noise is reduced, and the usage quality of the space of the roof is improved.
Description
Technical field
The present invention relates to building engineering field, particularly relate to roofing HVAC pipe well structure.
Background technology
The roof space is worth and is more and more fully excavated and utilize, improve the form that the performance of ventilating of roof airduct well in Practical Project uses and acoustic efficiency, optimization are originally undesirable, need to take some measures solve ventilation, the requirement of rate of being stopped by rain, noise reduction and four one attractive in appearance, support and improve the comfort level of roofing space environment quality and people's accomodation of activities in the roof space.
The general form adopting stormproof louvre of blinds design of roofing airduct well, the available ventilation area that the general design experiences value of available ventilation area of stormproof louvre gets 0.3-0.5(Pierced Aluminum Plank can reach 0.7-0.75), but stormproof louvre when meet be stopped by rain rate, actual ventilation does not generally all reach design load, unless blinds area is very large, generally do not accomplish not only rainproof but also meet air-conditioning requirement.
The cross correlation of wind speed and noise: if civil engineering pipe well condition does not allow to output enough large blinds area, improving ventilation speed is the measure generally can taked.But wind speed is not again a design load that can infinitely improve, and general wind speed is 2-4.5m/s, and wind speed is larger, noise also can be larger, and on roofing, large noise can reduce the quality that the roof space uses.
Summary of the invention
The main purpose of the present invention's structure is effectively improving the actual air intake of roof airduct well and the amount of air draft; Again for reducing noise thus the using character of the raising roof space.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: arrange ventilation enlarged cavity in the surrounding of the prefabricated airduct well of HVAC; Vented perforation aluminium sheet is provided with at the peripheral wall of described ventilation enlarged cavity and top; Directly over the prefabricated airduct well of described HVAC, arrange aluminium sheet top cover, described aluminium sheet top cover top mark is high identical with the vented perforation aluminium sheet top mark height at described top; In the surrounding close neighbour position, roofing civil engineering hole of the prefabricated airduct well of described HVAC, the concrete turned welt that keeps off the rain is set; Within the scope of described ventilation enlarged cavity, do outside roof drainage look for slope; Bottom the building pipe well of the prefabricated airduct well of described HVAC, floor drain is set.
The present invention by structure and technical finesse by of the prior art go out the peripheral structure of roofing airduct well outwards expand, increase ventilation cavity, change the stormproof louvre of periphery of the prior art into vented perforation aluminium sheet, and vented perforation aluminium sheet is set at the top of ventilation enlarged cavity.Improve ventilation rate by above-mentioned construction measure, thus resist wind speed, to reduce noise.
In addition, by keeping off the rain, the rainwater entering ventilation enlarged cavity blocks by concrete turned welt, looks for slope to dredge on large roofing by rainwater by the outside draining of ventilation enlarged cavity; Again by the floor drain bottom the building pipe well of the prefabricated airduct well of HVAC, by organized for the water of remnants collection and discharge, originally traditional mode of being stopped by rain is changed into the mode blocking water and combine with organized row's rain.
More useful economic benefit is reached: the cost directly reducing blinds type selecting on the one hand by structure and technical finesse; Reduce roofing noise on the other hand, optimize roof space quality, improve the economic benefit of roof space operation.
General available Pierced Aluminum Plank in the structure of this airduct well, also can use the material of the perforation of other various different ventilation rates, the vision needs coordinating the roof space to design.
Accompanying drawing explanation
Fig. 1 is airduct well construction plan view of the present invention.
Fig. 2 is the A-A sectional drawing of this Fig. 1.
The direction of arrow shown in Fig. 1 and Fig. 2 is air inlet mode signal, also can be reverse air-out mode, is only a kind of signal in figure.
Detailed description of the invention
As depicted in figs. 1 and 2: in the surrounding of HVAC prefabricated airduct well 4, ventilation enlarged cavity 2 is set; Vented perforation aluminium sheet 1 is provided with at the peripheral wall of ventilation enlarged cavity 2 and top; Directly over the prefabricated airduct well 4 of HVAC, arrange aluminium sheet top cover 7, aluminium sheet top cover 7 top mark is high identical with the vented perforation aluminium sheet 1 top mark height at top; Arrange in the surrounding close neighbour position, roofing civil engineering hole of the prefabricated airduct well 4 of HVAC and to keep off the rain concrete turned welt 3, the keep off the rain height of concrete turned welt of general recommendations is 350 millimeters; In ventilation enlarged cavity 2 scope, do outside roof drainage look for slope 5, namely the height point of weathering is located at concrete turned welt 3 place of keeping off the rain, and low spot is located at Pierced Aluminum Plank 1 place of peripheral wall, and general recommendations draining looks for the gradient on slope 5 to be 2%; Bottom the building pipe well of the prefabricated airduct well 4 of HVAC, floor drain 6 is set.
Above the scheme that the embodiment of the present invention provides is introduced in detail, for one of ordinary skill in the art, according to the thought of the embodiment of the present invention, all will change in specific embodiments and applications.As this structure also can paste wall arrange, now, the prefabricated airduct well of HVAC be wall, other three limits outwards arrange the same configuration such as ventilation enlarged cavity, vented perforation aluminium sheet; This structure also reliable corner is arranged, and now, the both sides of the prefabricated airduct well of HVAC are wall, and both sides outwards arrange the same configuration such as ventilation enlarged cavity, vented perforation aluminium sheet in addition.
In sum, this description should not be construed as limitation of the present invention, and all any changes made according to design philosophy of the present invention are all within protection scope of the present invention.
