Building top layer anti-seepage structure

Abstract

The invention relates to a building top layer anti-seepage structure. An anti-seepage device comprises a trough plate mounted on the top wall of a building; transverse plates are fixedly arranged on the two sides of the trough plate; longitudinal support columns are fixedly arranged below the transverse plate; the bottom of the trough plate is in communication with a water outlet pipe; the water outlet pipe is in communication with a water delivery pipe; the water delivery pipe is in communication with a drain pipe; the lower part of the drain pipe is in communication with a blow-off pipe; theblow-off pipe is in communication with the top of a longitudinal drainage hole of the building; a top flat plate is arranged above the trough plate; the top flat plate is provided with water leakageholes; and the inner side bottom of an outer waterproof layer is fixedly connected with the tops of the transverse plates. The building top layer anti-seepage structure has the advantages of convenience in operation, high working and running efficiencies, long service life, good waterproofing effect, remarkable heat-insulating effect, high overall outer flatness, complete drainage, insusceptibility to storing of water, assembled structure, convenience in transportation, mounting and disassembling, and good social and economic benefits.

Description

technical field [0001] The invention relates to the field of construction, in particular to an anti-seepage structure on the top floor of a building. Background technique [0002] After the construction of the building is completed, the exterior of the top floor slab needs to be protected. This treatment includes flatness, heat insulation layer, waterproof layer and other components to ensure that the top floor of the building will not be overcooled or overheated due to climatic factors. Occurs, and guarantees that the top floor will not leak due to rain and snow. [0003] However, after the top waterproof layer is treated, the aging phenomenon of the waterproof layer will occur as the building's service time increases. As the current top-layer waterproofing mostly uses asphalt to pave the top-layer structure to implement anti-seepage work, but after a long time of use, the asphalt will age and lose its anti-seepage effect. [0004] To sum up, the anti-seepage water on the...

As the current top-layer waterproofing mostly uses asphalt to pave the top-layer structure to implement anti-seepage work, but after a long time of use, the asphalt will age and lose its anti-seepage effect

[0004] To sum up, the anti-seepage water on the top floor of traditional buildings is mostly implemented by blocking and controlling seepage. This kind of structure has a short service life and is easily affected by weather and environmental factors, resulting in the loss of the anti-seepage effect.

In addition, in the top floor structure of traditional houses, the interior of the top floor is overheated in summer due to direct sunlight exposure, and the temperature inside the top floor is relatively low in winter due to the lack of a protective layer on the outside.

The traditional method is to set an insulation layer on the outside of the top floor of the house, and use the air insulation mode of the insulation layer to implement sun protection and heat preservation operations. If the roof is unstable or there are potholes in these gaps, it will cause water storage. The water accumulated here will always be in a state of accumulation. Since the upper space is relatively airtight, it is difficult for this part of the deposited water to evaporate. After a long time, it will appear that the cracks in the waterproof layer of the roof will seep into the top floor of the house, causing water leakage or water seepage.
