Building flashing

Abstract

The invention discloses a rainproof plate for a building. The rainproof plate comprises a metal plate, wherein the middle part of the metal plate is hollow; one end of the metal plate is an arc-shapedsection and the other end of the metal plate is an opening end; a sealed water storage cavity is formed in the middle of the metal plate; an extending plate is inserted into the opening end; one or more through holes are formed in an upper end face of the metal plate; a positioning needle is fixedly welded on the bottom surface of the water storage cavity aligned to each through hole; a floatingball is arranged in a manner of penetrating each positioning needle; the outer diameter of the floating balls is equal to the inner diameter of each through hole; one side, far away from the positioning needle, of each through hole is a spherical limiting surface; each floating ball is buckled into the corresponding spherical limiting surface and partially stretches out of the outer part of the metal plate. In rainy days, the rainproof plate can be used for collecting external rainwater; after the rainwater is collected, the floating balls can be floated through the rainwater and the through holes are sealed; when the rainwater falls onto the floating balls, the noises of the rainwater can be effectively reduced; in sunny days, the stored water can be used for effectively cooling the wholerainproof plate, so that indoor temperature is reduced; the extending plate can be ejected in rainy days so that the rainproof area is enlarged.

Description

technical field [0001] The invention relates to a rainproof board, in particular to a building rainproof board. Background technique [0002] In many simple buildings, we will use metal rainproof panels as the simple rainproof top surface of the entire building. When this metal rainproof panel is in rainy weather, the rain will wash on the rainproof panel, which will cause a lot of damage. Loud noise causes noise pollution to people in the room and cannot communicate normally; and when it is not raining on a sunny day, the indoor temperature rises sharply due to the poor heat insulation of the metal plate, and there are many deficiencies in its use . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a building rainproof board, which can effectively collect rainwater, and can push out the floating ball, and can use the floating ball to reduce the noise of rainwater, and use the stored water to effectively insulate ...

[0002] In many simple buildings, we will use metal flashings as the simple rainproof top surface of the entire building, and this metal flashing will cause a lot of damage when the rain washes on the flashing in rainy days. Loud noise causes people in the room to be polluted by noise and unable to communicate normally; and when it is not raining on a sunny day, the indoor temperature rises sharply due to the poor heat insulation of the metal plate, and there are many deficiencies in its use
