Description

Double-row bucket

Technical Field

The utility model relates to a drainage and steam exhaust device, namely a double-row bucket, which is mainly applied to a building roof and used for discharging accumulated water and moisture in a roof heat-insulating layer.

Background

GB50345-2012 roofing engineering specification 4.4.5 states that the roof exhaust structure should comply with the following regulations:

(1) the dividing joint arranged on the leveling layer can be used as a steam exhaust passage, and the width of the steam exhaust passage is preferably 40 mm;

(2) the steam exhaust channel is communicated with the air and the exhaust pipe communicated with the atmosphere, and the steam exhaust hole can be arranged under the cornice or at the intersection of the vertical and horizontal steam exhaust channels;

(3) the longitudinal and transverse spacing of the steam exhaust passage is preferably 6m, and the area of the roof is 36m ² A steam exhaust hole is preferably arranged and is subjected to waterproof treatment;

(4) plastic boards with fulcrums can also be laid under the heat preservation layer.

The 8 th item generally specified in the common general knowledge of the general regulations in the second chapter of the courseware of the technical Specification GB50345-2018 and the inverted roof technical Specification JGJ230-2018 indicates that the roof exhaust steam structure meets the following regulations:

(1) dividing seams arranged on the leveling layer can be used as an exhaust passage, and the width of the exhaust passage is preferably 40 mm;

(2) the exhaust channel is communicated with the exhaust pipe communicated with the atmosphere in a longitudinal and transverse mode, and the exhaust hole can be arranged under the cornice or at the intersection of the longitudinal and transverse exhaust channels;

(3) the longitudinal and transverse spacing of the exhaust passage is preferably 6m, and the area of the roof is 36m ² An exhaust hole is preferably arranged and is subjected to waterproof treatment;

(4) a plastic plate with a fulcrum can also be laid under the heat preservation layer, and water and air are discharged through the cavity layer.

It can be seen that 'steam' in the technical specification of the roof engineering of GB50345-2012 and 'gas' in the technical specification of the roof engineering of GB50345-2018 and the technical specification of the inverted roof JGJ230-2018 teach that 'gas' is a meaning in courseware, and in the field of building, 'steam barrier' and 'gas barrier' are often mixed, so that 'steam' and 'gas' written in the present invention are also a meaning. The steam discharge structure in the above two specifications has basically the same items (1), (2) and (3), and in item (4), after 'a plastic plate with a fulcrum can be laid under the heat preservation layer', the latter adds 'water discharge and air discharge through the cavity layer'. Therefore, the purpose of the specification is to control water and steam in the insulating layer to gather under the insulating layer, and the latter specification is more clearly expressed. At present, all roof engineering technologies only design steam vents, and although moisture can be discharged upwards from a steam discharge pipe through the steam vents, accumulated water flows downwards, so that the accumulated water cannot be discharged from the steam vents.

Can see through above standard regulation, the downthehole ponding of roofing insulation, moisture all wait for them to become gaseous back, lean on the steam vent to discharge slowly, if only a small amount of moisture, can also solve the steam exhaust problem through the steam vent, but in fact, a lot of seepage roofing all has a large amount of ponding in the insulation, lean on evaporative emission far away not enough. The technical specifications are introduced from the sixty-seven years of the last century, the thermal insulation material used in the thermal insulation layer is cement perlite or asphalt perlite, and accumulated water basically does not flow in the cement perlite or the asphalt perlite and can only be slowly discharged from the steam vent through evaporation. The existing roof heat-insulating layer material uses the extruded sheet to replace cement perlite, the extruded sheet does not absorb water, accumulated water or moisture has good water mobility and steam mobility in gaps of the extruded sheet, the moisture can return upwards through the gaps of the heat-insulating plate, and the accumulated water can naturally gather under the heat-insulating layer. From the real roofing seepage condition, all there is ponding in the seepage roofing insulation can, the condition is serious, and ponding can reach more than 100mm in the insulation can, and the steam vent does not have quick drainage function, can not satisfy drainage, steam extraction needs.

The utility model discloses a double-hopper comprises base and apron two parts, and the pedestal mounting is in the roofing structural layer, and the firm strip of base is inlayed in the structure layer of looking for slopes or the screed-coat, and the steam barrier or invert the waterproof layer and accomplish on the base panel plane. The base outlet is connected with the exhaust drum of the roof of a kitchen or a toilet indoors, the cover plate covers the base, the inverted waterproof layer is arranged below the cover plate filter column, water and steam in the heat preservation layer are collected and discharged through the base, and are shunted in the exhaust drum, the steam moves upwards and is discharged from the exhaust port, the water flows downwards, enters the exhaust drum drainage channel and flows to the building drainage pipe network.

GB50345-2012 roofing engineering specification 5.3.4 section 4 states that metal or plastic exhaust pipes can be embedded at the intersections of the longitudinal and transverse exhaust ducts of the roof, the exhaust pipes are preferably arranged on the structural layer, and holes should be punched through the insulating layer and around the pipe walls of the exhaust ducts. In cold winter, a thick layer of frost is condensed on the inner wall of the roof exhaust pipe, and the frost flows into the heat-insulating layer from the exhaust hole after being converted into water. After the device of the invention, namely the double-row bucket, is installed, the roof is not provided with a steam exhaust hole, and a steam exhaust pipe is not installed, so that the hidden trouble can be avoided forever.

On the roof with a small area, the double-row bucket can completely replace steam exhaust holes, and on the roof with a large area, the double-row bucket can be supplemented with other water and steam exhaust devices, such as a three-row bucket and the like, so as to partially replace the steam exhaust holes (the three-row bucket is another water and steam exhaust device developed based on the same idea, and has the functions of collecting and discharging roof rainwater, discharging water and moisture accumulated on a heat-insulating layer, ventilating the heat-insulating layer and the like). Because the double-row bucket is arranged in the heat-insulating layer, steam is exhausted outwards by virtue of the steam exhaust barrels of the kitchen and the toilet, the roof does not have steam exhaust holes, and the steam exhaust pipe is not arranged, thereby eliminating the hidden trouble that the steam exhaust pipe is damaged and changed into a roof leakage point.

Disclosure of Invention

The utility model discloses the device is in order to solve the interior ponding of roofing heat preservation and can not in time excrete and the slow difficult problem of moisture emission. The proposal for solving the problem is to design a double-drain device of water and steam, namely a double-drain bucket.

The accumulation of the accumulated water and the moisture under the roof heat-insulating layer and the mobility of the water and the steam in the gaps of the extruded sheet provide feasibility for the installation and the use of the double-row bucket device of the utility model. Compared with steam exhaust holes, the double-drain-bucket steam exhaust area is larger, 1 double drain bucket can replace a plurality of steam exhaust holes, and the double drain buckets are installed, so that the roof steam exhaust holes are cancelled, the open steam exhaust of the steam exhaust holes is changed into the blind steam exhaust of the double drain buckets, and the drainage of accumulated water and moisture in a heat-insulating layer is facilitated.

The double-row bucket is composed of a base and a cover plate, the base is arranged in a roof structure, a base water outlet is connected with a kitchen and toilet roof exhaust funnel indoors, a base panel and a structure slope finding layer or a leveling layer are at the same height, a cover plate supporting column is downwards arranged in the base and is jointly acted by a cover plate filtering column, a supporting column, blades and the inner wall of the base, a water and steam discharging channel is formed between the cover plate and the base (on a steam isolating layer or an inverted waterproof layer), and meanwhile, sundries can be filtered by the cover plate filtering column. The base is thick at the top and thin at the bottom, and is provided with a variable diameter, the thick at the top is beneficial to collecting accumulated water, and the thin at the bottom is beneficial to being connected with the exhaust funnel. The base stabilizing strip is arranged below the base panel and embedded in the structure slope finding layer or the leveling layer to play a role of stabilizing the base. The lower end of the base is connected to an exhaust funnel of an indoor kitchen or toilet, the lower end of the exhaust funnel is connected with a sewer pipe network, the upper end of the exhaust funnel is higher than a roof and is communicated with the atmosphere, when excessive water is accumulated in a heat-insulating layer of the roof, the double-row hopper discharges the accumulated water in the heat-insulating layer through a sewer passage of the exhaust funnel (the accumulated water in the heat-insulating layer is limited, the flow is far smaller than the water flow of the kitchen or toilet, the normal use function of the kitchen or toilet cannot be influenced), and when steam pressure exists in the heat-insulating layer of the roof, gas can enter the double-row hopper through gaps of the extruded sheet and is discharged into the air through the exhaust funnel. The filter column can filter sundries and prevent the sundries from flowing into the base, and can support the cover plate to keep a certain distance from the base, so that the accumulated water is discharged smoothly. The support columns and the blades can ensure that the cover plate is stabilized at the central position above the base.

When water and steam in the heat-insulating layer flow through the exhaust funnel through the double drain hoppers, the water and the steam are divided, the steam flows upwards, the water flows downwards, and the principle of the water and the steam division is the same as that of the water and the steam after the water flows to the exhaust funnel in a kitchen and a toilet. Thus, the double-drain bucket realizes double drainage of water and steam. Accumulated water and moisture in the heat-insulating layer are discharged in time, so that the potential danger of house leakage can be reduced, the heat-insulating performance of the heat-insulating layer can be improved, and the service life of roof water resistance and heat insulation is prolonged.
