Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
Please refer to fig. 1, the utility model discloses an existing building basement bottom plate construction joint waterproof construction, include:
the original bottom plate 10 is provided with a first joint face 11, a second joint face 12 and a third joint face 13 which are connected in sequence, the second joint face 12 is perpendicular to the first joint face 11 and the third joint face 13 respectively, and the first joint face 11 is positioned at one end close to the upper surface of the bottom plate; a reserved space is formed in one end, far away from the second joint surface 12, of the third joint surface 13, and the reserved space is filled with an advanced water stopping bag 30;
a new floor panel 20 is created which is simultaneously attached to the first joint face 11, the second joint face 12 and the third joint face 13.
The first joint face 11, the second joint face 12 and the third joint face 13 are connected in sequence, and meanwhile, the second joint face 12 is perpendicular to the first joint face 11 and the third joint face 13 respectively, so that the joint area between the original bottom plate 10 and the newly-built bottom plate 20 is greatly increased, the water seepage path of the bottom plate is further increased (the path that water sequentially penetrates through the third joint face 13, the second joint face 12 and the third joint face 13 from the water facing surface), and the waterproof performance of the bottom plate is greatly improved.
The reserved space is arranged on the upstream surface of the original bottom plate 10.
The reserved space is located on the upstream side, and the advanced water stopping bag 30 is filled in the reserved space to provide a first waterproof measure for the reconstruction bottom plate, so that most water can be prevented from entering the third joint surface 13.
And a water-swelling water stop strip 40 is arranged between the first joint surface 11 and the newly-built bottom plate 20.
And a water-swelling water stop strip 40 is arranged between the second joint surface 12 and the newly-built bottom plate 20.
And a water-swelling water stop strip 40 is arranged between the third joint surface 13 and the newly-built bottom plate 20.
Since most of the water is isolated by the leading water stopper 30, the water that can reach the third joint face 13 through the leading water stopper 30 is a very small part, and therefore, the water-swellable seal 40 of the three joint faces can completely prevent the water penetrating from the leading water stopper 30 from penetrating to the upper surface of the bottom plate, which is a second measure of waterproofing for rebuilding the bottom plate.
The first joint surface 11 is fixedly provided with a plurality of drainage conduits 50, and the drainage conduits 50 are connected through a plurality of tee joints.
A hydrophobic conduit 50 is provided at the first joint face 11, i.e. the joint face closest to the upper surface of the sole plate, as a final waterproofing measure for the reconstructed sole plate. When the lead water stopper 30 or/and the water-swellable seal 40 fail, the hydrophobic conduit 50 may direct water into a nearby catchment well without flowing directly to the upper surface of the base plate, thereby ensuring a substantially constant waterproof performance of the reconstituted base plate.
The interval between any two adjacent hydrophobic conduits 50 is 3-5 meters.
The leading water stopper 30 has a thickness of 1/3 to 1/2 of the thickness of the bottom plate.
The leading water stopper 30 has a thickness of 3/7 mm of the bottom plate.
The reason why the leading water stopper 30 is made 1/3 to 1/2 thick as the bottom plate is to ensure the waterproof performance of the leading water stopper 30 without wasting material and further reduce the construction cost.
The width of the headspace is 3/7 the thickness of the bottom panel.
In this embodiment, the bottom plate has a thickness of 700mm, and the height of the reserved space and the thickness of the leading water stopper 30 are both 300 mm.
When the first joint surface 11, the second joint surface 12 and the third joint surface 13 are all provided with grooves, the newly-built base plate 20 is correspondingly provided with convex strips; or when the first joint surface 11, the second joint surface 12 and the third joint surface 13 are all provided with convex strips, the newly-built base plate 20 is correspondingly provided with grooves; the engagement of the ribs into the grooves increases the strength of the connection, making the connection between the newly-built base plate 20 and the original base plate 10 tighter.
The three joint surfaces are dug into the rabbet shape, so that the joint area of the new and old bottom plates can be further increased, the connection between the newly-built bottom plate 20 and the original bottom plate 10 can be more compact, and the connection strength of the bottom plates can be improved; the joint is arranged in a tongue-and-groove shape, so that a water seepage path can be increased, the difficulty of water penetrating the joint is increased, and the waterproof performance of the bottom plate is greatly improved.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
