Description

Double-row bucket

Technical Field

The invention relates to a drainage and steam exhaust device, namely a double-row hopper, which is mainly applied to a building roof and used for exhausting 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 vertical and horizontal steam exhaust pipes communicated with the atmosphere, and the steam exhaust holes can be arranged below the cornice or at the intersection of the vertical and horizontal steam exhaust channels;

(3) the longitudinal and transverse spacing of the steam exhaust channel is preferably 6m, and the area of the roof is 36m²A steam exhaust hole is preferably arranged and is subjected to waterproof treatment;

(4) plastic boards with supporting points 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) the dividing joint 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 36m²An 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'. It can be seen that the purpose of the two specifications is to control the water and steam in the insulating layer to gather under the insulating layer, and the latter specification is more clearly expressed. At present, the roof engineering technical specification only designs the steam exhaust hole, and although moisture can be upwards discharged from the steam exhaust pipe through the steam exhaust hole, accumulated water is discharged downwards, so that the accumulated water cannot be discharged from the steam exhaust hole.

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. These specifications were introduced from the sixty-seven years of the last century, and the insulating material used in the insulating layer was cement perlite or asphalt perlite, so that the accumulated water would not flow in the cement perlite or asphalt perlite, but would be slowly discharged from the steam vent by 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 invention relates to a drainage and steam exhaust device, in particular to a double-row bucket, which consists of a base and a cover plate, wherein the base is arranged in a roof structure layer, a base stabilizing strip is embedded in a structural slope layer or a leveling layer, and a steam barrier layer or an inverted waterproof layer is arranged on the plane of a base panel. The water outlet of the base is connected with the steam exhaust barrel of the roof of a kitchen or a toilet indoors, the cover plate covers the base, the inverted waterproof layer is arranged below the filter column of the cover plate, water and steam in the heat-insulating layer are collected and discharged through the double-drain-bucket base, and are shunted in the steam exhaust barrel, the steam moves upwards and is discharged from the steam exhaust port, the water flows downwards, enters the drainage channel of the steam exhaust barrel and flows to the drainage pipe network of the building.

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 drain buckets are installed, the roof is not provided with steam exhaust holes, and a steam exhaust pipe is not installed, so that the condition that condensed water flows into the heat insulation layer can be avoided.

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, exhausting accumulated water and moisture in the heat insulation layer, ventilating the heat insulation 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 invention aims to solve the problems that accumulated water in a roof insulation layer cannot be drained in time and moisture is slowly drained. The invention solves the problem by designing a double-drain device of water and steam, namely a double-drain bucket.

The accumulation of accumulated water and moisture under the roof insulation layer and the fluidity of water and steam in the gaps of the extruded sheet provide feasibility for the installation and the use of the device, namely the double-drain. Compared with the steam exhaust hole, 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 bucket is installed to cancel the roof steam exhaust hole, so that the open steam exhaust of the steam exhaust hole is changed into the dark steam exhaust of the double-drain bucket, and the drainage of accumulated water and moisture in the heat insulation layer is facilitated.

The double-row bucket is composed of a base and a cover plate, the base is installed 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 are at the same height, a cover plate support column is installed downwards in the base and is jointly acted by a cover plate filtering column, a support 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, the cover plate filtering column can be used for filtering sundries. 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. A base stabilizing strip is arranged below the base panel and embedded in the structural slope finding layer to play a role in 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 not only filter sundries and prevent the sundries from flowing into the base, but also support the cover plate to keep a certain distance with the base, thereby ensuring the accumulated water to be 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 hidden danger of house leakage can be reduced, the heat-insulating performance of the heat-insulating layer can be improved, and the waterproof heat-insulating service life of the roof can be prolonged.
