Percolation-proof building board
Technical field
The utility model relates to a kind of percolation-proof building board.
Background technology
The top of current building is overing number mud layer on top board mostly, because cement layer easily seeps water, therefore of long duration on the one hand after percolation-proof building board is arranged on roof, easily percolation-proof building board is rotted, also easily make moister within doors on the other hand; Simultaneously due to province's material material-saving feature of present building structure, make the soundproof effect between its upper and lower floor poor, therefore, it is possible to have influence on the quality of people's daily life.
Summary of the invention
The purpose of this utility model is to provide a kind of percolation-proof building board, and the technical problem that solve to eliminate the percolation-proof building board of roof cement layer seepage problem.
For solving the problem, the utility model realizes by the following technical solutions: a kind of percolation-proof building board, comprise the gypsum substrate that several piece is spliced mutually, the inner face surrounding of described gypsum substrate is provided with surrounding edge, gypsum substrate inner face is provided with spaced securing member, the inner face of described gypsum substrate is provided with at least one rhone, on the relative both sides of surrounding edge, the drain hole be connected with rhone is provided with corresponding section, rhone position, the outer face of gypsum substrate is provided with the first waterproofing course, the lower surface of the first waterproofing course is provided with decorative cover flaggy, fluid sealant is filled with in gap between adjacent two pieces of gypsum substrates, building wall is provided with the gutter corresponding with drain hole position, and the drain hole on the surrounding edge of the gypsum substrate that gutter is other with being arranged on building wall is connected, and gutter is also connected with the drainage pipe of building.
Securing member described in the utility model is angle bar, and one end of securing member is fixed by the smallpox of setscrew and building, and the other end of securing member is connected and fixed by the inner face of self-tapping screw and gypsum substrate.
Gutter described in the utility model is embedded in building wall.
The inner face of gypsum substrate described in the utility model is inclined-plane.
The utility model compared with prior art, because the gypsum surface arranged is provided with surrounding edge, utilize rhone, drain hole and gutter, avoid cement layer infiltration and cause moisture issues in room, eliminate the moisture accumulating in gypsum plank upper end, the waterproofing course simultaneously arranged when steam is not eliminated completely, can play protective action.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises the gypsum substrate 1 that several piece is spliced mutually, gypsum substrate 1 splices to building wall place always, the inner face surrounding of every block gypsum substrate 1 is provided with surrounding edge 2, gypsum substrate 1 inner face is provided with spaced securing member 4, and described securing member 4 is angle bar, and the vertical edge of securing member 4 is fixed by swell fixture and building smallpox, the vertical edge of securing member 4 welds with swell fixture, and the horizontal edge of securing member 4 is fixed by the inner face of self-tapping screw and gypsum substrate 1; The inner face of gypsum substrate 1 is provided with at least one rhone 5, rhone 5 is preferably one, drain hole 6 is provided with on the relative both sides of surrounding edge 2, with corresponding section, rhone 5 position, two drain holes 6 are connected with the two ends of rhone 5 respectively, be interconnected between drain hole 6 on adjacent two pieces of gypsum substrates 1, the outer face of gypsum substrate 1 is provided with the first waterproofing course 7, the lower surface of the first waterproofing course 7 is provided with decorative cover flaggy 8, in the gap between adjacent two pieces of gypsum substrates 1, is filled with fluid sealant 9; Building wall is provided with gutter 3, and the drain hole 6 on the surrounding edge 2 of the gypsum substrate 1 that gutter 3 is other with being arranged on building wall is connected, and described gutter 3 is arranged on wherein gutter 3 and can be embedded in building wall, and gutter 3 is connected with the drainage pipe of building.
In the present embodiment, gutter 3 can be connected with the drain hole 6 that wherein side or both sides are arranged on the surrounding edge 2 of the other gypsum substrate 1 of building wall.
During installation, the rhone 5 of every block gypsum substrate 1 is arranged towards same direction, and is interconnected, make between itself and gutter 3, to form a drainage channel.
As shown in Figure 2, the inner face of gypsum substrate 1 is inclined-plane, and its incline direction is successively decrease highly successively from the both sides of gypsum substrate 1 towards rhone 5, makes it possible to ponding to be drained in rhone 5.
First waterproofing course 7 of the present utility model adopts polyethylene polypropylene fiber composite sheet.
