Water-drive photothermal impermeable building exterior wall

Abstract

The invention discloses a water-drive photothermal impermeable building exterior wall, and belongs to the field of construction technology. Through the form of evenly arranging water-drive photothermal balls on the outer surface of the exterior wall and water phototatic composite tubes which are embedded in the exterior wall during construction and connected to the water-drive photothermal balls,once rainwater penetration occurs to the exterior wall, the water-drive composite tubes can absorb permeating water from the exterior wall and then transfer the permeating water to the water-drive photothermal balls to trigger the photo-thermal conversion action, through the water shrinkage feature of rear water shrinkage pull rods, reflective flaps on the surfaces of the water-drive photothermalballs are pulled to deform and fit along photothermal ball grooves, internal photothermal conversion layers are unfolded, the photothermal conversion layers are matched with the reflective flaps to absorb light and convert light into heat energy, and heat is also transmitted to the depths of the exterior wall through the water-drive composite tubes for heating and evaporating the permeating water,then water vapor flows from the water-drive composite tubes to the photothermal ball grooves and dissipates to the outside, thus, the water penetration problem of the exterior wall can be effectivelysolved, and the service life of the exterior wall is prolonged.

Description

technical field [0001] The invention relates to the technical field of buildings, and more specifically relates to a water-tightening type anti-seepage building exterior wall. Background technique [0002] The outer wall is defined by the judgment method. Let A-B be a wall. If the A-B wall line can cut the relevant enclosure structure, it is an inner wall, otherwise it is an outer wall. From an architectural point of view, the enclosure of a building to form an indoor and outdoor boundary component is called an exterior wall. Its functions are: bear a certain load, shelter from wind and rain, thermal insulation, noise prevention, fire safety, etc. [0003] Wall materials generally have many tiny holes, or there will be some penetrating gaps due to improper installation or material shrinkage. Due to the existence of these holes and gaps, the impermeability of the outer wall of the building is poor. In the prior art, when constructing the outer wall, impermeable concrete is ...

AI Technical Summary

Problems solved by technology

[0005] However, starting with raw materials and construction, the effect of anti-seepage is poor, especially after a certain service life, the anti-seepage effect decreases, or in the rainy season, the intensity of external force intervention is relatively large, and only the outer wall itself is used for anti-seepage Often unsatisfactory, there will still be permeability problems, seriously affecting the user's living experience and the service life of the external wall
