Abstract

The utility model provides an exhaust and antiseep structure of heat preservation roofing which characterized in that: at the pre -buried standpipe of expansion joint to outer wall juncture that cornices, the sump pit shape is made on standpipe upper portion, the horizontal breather pipe of reservation in the heat preservation of the waterproof roofing that keeps warm to be connected to the sump pit within range of standpipe, has laid the air vent on the horizontal breather pipe, the utility model discloses it is even that the inside and outside atmospheric pressure of heat preservation is maintain to horizontal breather pipe, and it is unanimous with outdoor atmospheric pressure that the heat preservation is maintain to the standpipe, avoids having improved integrality, the reliability on roof waterproof layer at roofing upper portion destruction waterproof layer reservation breather pipe, utilizes hot -air come -up effect to avoid the cold air to immerse the heat preservation, improves roofing thermal insulation performance. During the unexpected seepage of roof waterproof, advection to sump pit on the roof boarding is discharged from the standpipe and is dripped, plays early warning function in advance before piercing through reinforced concrete leaking, and the tip of pre -buried standpipe at the expansion joint of cornicing plays the diffusion concentrated stress, plays the fissured effect of collar tie beam that prevents.

Description

The aerofluxus of a kind of heat insulation house surface and anti-leakage structure

Technical field

This utility model belongs to power transmission and distribution and electricity consumption Engineering Speciality transformer station power transformation engineering Architectural Structure Design technical field, relates to transformer station's projecting-eave type insulation cornice anticracking of flat roof deck, roofing exhaust constructs with antiseep.

Background technology

In recent years, in power transformation engineering, building uses projecting-eave type flat roof deck in a large number, also some engineering problems and deficiency are exposed, especially cold district cornices and collar tie beam irregularly ftractures, exhaustor ventilation affects around heat insulation effect, waterproof layer seepage, roofing surrounding and exhaustor the problems such as waterproof layer cementing material inefficacy and often occurs, cause roofing to leak without early warning, bring hidden danger to the normal production run of transformer station.

Utility model content

The purpose of this utility model is to provide a kind of aerofluxus being applied to heat insulation house surface and anti-leakage structure, the positive and negative air-pressure that release roofing heat-insulating layer variations in temperature causes in time, prevents roofing from deforming, improves the integrity of roof waterproof layer, reliability；Improve roof heat insulation performance, moreover it is possible to stop the expansion joint stress that cornices to be concentrated and cause collar tie beam crack.

For achieving the above object, this utility model provides aerofluxus and the anti-leakage structure of a kind of heat insulation house surface, it is characterized in that: be stitched to the pre-buried vertical tube of exterior wall intersection cornicing to stretch, riser upper portions makes catch pit shape, reserved horizontal breather in the heat-insulation layer of thermal-insulating water-proof roof, and in the range of being connected to the catch pit of vertical tube, level ventilation pipe is laid with passage.

Vertical tube lower end is cusp-shaped.

Level ventilation pipe upper vent hole presses 0.5 ~ 1.0 meter of uniform laying of spacing.

This utility model level ventilation pipe maintains heat-insulation layer inner and outer air pressure uniform, vertical tube maintains heat-insulation layer consistent with outside atmosphere pressure, avoid destroying waterproof layer on roofing top and reserve breather, improve the integrity of roof waterproof layer, reliability, utilize hot-air floating effect to avoid cold air to sink to heat-insulation layer, improve roof heat insulation performance.During roof waterproof accident seepage, on roof boarding, advection is to catch pit, discharges from vertical tube and drips, leak penetrate armoured concrete slab before play the effect of giving warning in advance, pre-buried vertical tube plays diffusion concentrated stress in the end at expansion joint of cornicing, and plays the effect in prevention collar tie beam crack.

Accompanying drawing explanation

Fig. 1 is floor map of the present utility model；

Fig. 2 is generalized section of the present utility model.

Detailed description of the invention

With reference to Fig. 1, Fig. 2, structure of the present utility model is made up of tip vertical tube 1, expansion joint 2 of cornicing, level ventilation pipe 3, thermal-insulating water-proof roof 4.

nullSetting is suitably encrypted at the expansion joint 2 of cornicing of BUILDINGS IN COLD AREAS thing，It is advisable for 6 ~ 10 meters，At expansion joint 2 to the exterior wall intersection pre-buried tip vertical tube 1 that cornices，Catch pit shape is done on top，Reserved horizontal breather 3 in the heat-insulation layer of thermal-insulating water-proof roof 4，Level ventilation pipe 3 overall length presses the uniform laying breeder tube of spacing 0.5 ~ 1.0 meter，And in the range of being connected to the catch pit of tip vertical tube 1，It is uniform that level ventilation pipe 3-dimensional holds heat-insulation layer inner and outer air pressure，Tip vertical tube 1 maintains heat-insulation layer consistent with outside atmosphere pressure，Avoid destroying waterproof layer on roofing top and reserve exhaustor，Improve the integrity of roof waterproof layer、Reliability，Hot-air floating effect is utilized to avoid cold air to sink to heat-insulation layer，Improve roof heat insulation performance，During roof waterproof accident seepage，On roof boarding, advection is to catch pit，Discharge from tip vertical tube 1 and drip，Leak penetrate armoured concrete slab before play the effect of giving warning in advance，Pre-buried tip vertical tube 1 plays diffusion concentrated stress in the end at expansion joint 2 of cornicing，Play the effect in prevention collar tie beam crack.
