The embodiment of the utility model provides a pair of outer wall windowsill concrete tongue-and-groove node waterproof construction, through set up the stagnant water tongue-and-groove on the outdoor window mesa of concrete windowsill, the stagnant water tongue-and-groove is close to the height that highly is higher than near outdoor one side of indoor one side, and the rainwater waters on the stagnant water tongue-and-groove, makes the rainwater down-flow along the stagnant water tongue-and-groove, prevents that the rainwater from invading the indoor side of windowsill, and the window opening water-proof effects is good.
Description
Technical Field
The utility model relates to the technical field of building, in particular to outer wall windowsill concrete tongue-and-groove node waterproof construction.
Background
The current construction method is concrete cast-in-place windowsill, waterproof mortar or polyurethane foaming agent is filled between the windowsill and a window frame, cement mortar is more than or equal to 5 percent of slope finding plastering and coating facing, and due to the fact that the waterproof mortar and the facing mortar have drying shrinkage cracks, long-term rain or high-wind-pressure rain can leak indoors along the interface of the concrete windowsill to form common problems of windowsill leakage quality.
SUMMERY OF THE UTILITY MODEL
An embodiment of the utility model provides an outer wall windowsill concrete tongue-and-groove node waterproof construction for solve the universal defect of concrete windowsill interface seepage.
In order to solve the problem that the above-mentioned background art provided, the embodiment of the utility model provides an outer wall windowsill concrete tongue-and-groove node waterproof construction, include: the upper part of the concrete windowsill is provided with a water-stopping rabbet and a window frame, and the height of the indoor side of the water-stopping rabbet is higher than that of the outdoor side of the water-stopping rabbet.
Preferably, the slope of the outer low-order table top of the water-stopping tongue-and-groove is not less than 5% when the table top is sloping outwards.
Preferably, the inner side surface of the opening of the concrete windowsill is coated with waterproof mortar.
Preferably, the outer side surface of the waterproof mortar is coated with a waterproof coating, and a gap between the window frame and the opening of the concrete windowsill is coated with a polyurethane foaming agent.
Preferably, the outer side surface of the concrete windowsill is sequentially provided with a heat insulation layer and a facing from inside to outside, the heat insulation layer is arranged on the outer side of the waterproof coating film, and weather-resistant glue is coated on the joint of the facing.
The utility model has the advantages that:
the embodiment of the utility model provides a pair of outer wall windowsill concrete tongue-and-groove node waterproof construction, through set up the stagnant water tongue-and-groove on the outdoor window mesa of concrete windowsill, the stagnant water tongue-and-groove is close to the height that highly is higher than near outdoor one side of indoor one side, and the rainwater waters on the stagnant water tongue-and-groove, makes the rainwater down-flow along the stagnant water tongue-and-groove, prevents that the rainwater from invading the indoor side of windowsill, and the window opening water-proof effects is good.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by the practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
The technical solution of the present invention is further described in detail by the accompanying drawings and examples.
Drawings
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention.
In the drawings:
fig. 1 is a side sectional view of an embodiment of the present invention.
Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
As shown in fig. 1, an embodiment of the utility model provides an outer wall windowsill concrete tongue-and-groove node waterproof construction, include: the concrete windowsill 1 is provided with a window frame 2 and a water-stopping rabbet 3 at the upper part, the height of the indoor side of the water-stopping rabbet 3 is more than or equal to 30mm higher than that of the outdoor side, and the outward slope of the low-order table top outside the water-stopping rabbet 3 is not less than 5%.
In the embodiment, the water-stopping rabbet 3 is arranged on the outdoor windowsill surface of the concrete windowsill 1, the height of the indoor side of the water-stopping rabbet 3 is higher than that of the outdoor side, rainwater is poured on the water-stopping rabbet 3, so that the rainwater flows downwards along the water-stopping rabbet 3, the rainwater is prevented from entering the indoor side of the concrete windowsill 1, and the waterproof effect of a window opening is good.
The inner side surface of the opening of the concrete windowsill 1 is coated with waterproof mortar 4; the outer side surface of the waterproof mortar 4 is coated with a waterproof coating 5, in the embodiment, the waterproof coating 5 is a polymer waterproof coating, and a polyurethane foaming agent 6 is coated on a gap between the window frame 2 and the opening of the concrete windowsill 1; the outer side surface of the concrete windowsill 1 is sequentially provided with a heat insulation layer 7 and a facing 8 from inside to outside, the heat insulation layer 7 is arranged on the outer side of the waterproof coating film 5, and weather-resistant glue 9 is coated on the joint of the facing 8.
In the embodiment, the inner side surface of the opening of the concrete windowsill 1 is coated with the waterproof mortar 4, the outer side surface of the waterproof mortar 4 is coated with the waterproof coating 5, then the window frame 2 is installed, and the gap between the window frame 2 and the opening of the concrete windowsill 1 is coated with the polyurethane foaming agent 6, so that the sealing property between the window frame 2 and the concrete windowsill 1 is further improved; set gradually heat preservation 7 and veneer 8 outside 1 lateral surface of concrete windowsill from inside to outside, 8 joints of veneer are brushed with resistant time and are glued 9, prevent that the rainwater from 8 joints of veneer entering 1 indoor of concrete windowsill, have improved water-proof effects.
