Detailed description of the invention
Fig. 1 is the structural schematic diagram of one embodiment of water proof anti-seepage structure outside post-cast strip provided by the utility model；
In figure, the post-cast strip 1-；2- separation layer；3- waterproof layer；4- exterior wall；5- back fill course.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Example is not intended to limit the scope of the present invention for illustrating the utility model.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified
Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary,
It can be the connection inside two elements.For the ordinary skill in the art, on can understanding as the case may be
State the concrete meaning of term in the present invention.
As shown in Figure 1, the utility model provides water proof anti-seepage structure outside a kind of post-cast strip, including separation layer 2 and waterproof layer
3；The outside of exterior wall 4 is arranged in separation layer 2, and opposite with the end of post-cast strip 1, for blocking shape between exterior wall 4 and post-cast strip 1
At notch；Waterproof layer 3 is arranged in the outside of exterior wall 4 and the outside of separation layer 2.
Specifically, for example, the width of separation layer 2 can be designed according to the actual situation on site with height, with can
It blocks and is arranged for the purpose of the notch between post-cast strip 1 and exterior wall 4；When post-cast strip 1 is wider, separation layer 2 is also corresponding wider；Exterior wall
4 is higher with the height of post-cast strip 1, and separation layer 2 is also corresponding higher；Separation layer 2 can be for certain thickness pier, isolation
The thickness of layer 2 can be in being backfilling and compacted after function, the water pressure of backfill and the combined factors such as economical consider to backfill
Setting；Under the premise of proof strength condition, separation layer 2 can be built from bottom to top by brick-on-end or building block mixed mortar and
At；The setting of separation layer 2 can stop indentation, there of the native stone in 4 outside of exterior wall between post-cast strip 1 and exterior wall 4 to enter building
Inside configuration avoids affecting indoor construction；For example, waterproof layer 3 can be made of asphalt water-proof coiled material, it can also be by height
Polymerized asphalt water-proof coiled material is made, and can also be made of synthetic polymeric waterproofing material, for example, waterproof layer 3 is by the red core of TPZ
Molecule glues polymer membranes and is made.Wherein, waterproof layer 3 is continuously arranged in the outside of exterior wall 4 and the outside of separation layer 2,
For example, the height of waterproof layer 3 is equal with the height of separation layer 2.The setting of waterproof layer 3 can stop the water penetration in 4 outside of exterior wall
To inside building structure, avoid affecting indoor construction.
Water proof anti-seepage structure outside post-cast strip provided by the utility model passes through the end phase in outside and post-cast strip in exterior wall
Separation layer is arranged in the position of alignment, later after the outside of exterior wall and the outside of separation layer arrangement waterproof layer, so that waterproof layer
It avoids forming the weakness zone of impervious leak in the seam crossing of exterior wall and post-cast strip；Meanwhile separation layer can be used as post-cast strip again
Permanent formwork when casting concrete offers convenience for construction.
Further, water proof anti-seepage structure further includes screed-coat outside the post-cast strip；Screed-coat is arranged in waterproof layer 3 after
Pour the side of band 1.Specifically, in order to improve the coating effect of waterproof layer 3, screed-coat can be set and make the metope with coating more
Add smooth；For example, the thickness of screed-coat can be 20mm, it is made after being mixed by cement and mortar according to the ratio of 1:2.5.
Further, water proof anti-seepage structure further includes insulating layer outside the post-cast strip；Insulating layer sets that be arranged in waterproof layer 3 close
The side of post-cast strip 1.Specifically, for example, the thickness of insulating layer can be made with 70mm of extruded polystyrene board.
Further, water proof anti-seepage structure further includes protective layer outside the post-cast strip；Protective layer sets that be arranged in waterproof layer 3 separate
The side of post-cast strip 1.Specifically, it for example, the thickness of protective layer can be 40mm, is made of pea gravel concreten.
Further, waterproof layer 3 includes that the red core molecules of one or more layers TPZ glue polymer membranes.It specifically, can be with
It is selected that one layer or multilayer TPZ red core molecules is used to glue polymer membranes as waterproof layer 3 according to waterproofing grade.
Further, water proof anti-seepage structure further includes back fill course 5 outside the post-cast strip；Back fill course 5 is arranged in waterproof layer 3
Side far from post-cast strip 1.Specifically, after after waterproof layer 3 arranges, the backfill of backfill is carried out, shortens the outer fertile slot of wall
Indwelling time, facilitate enhance waterproof layer 3 durability.
When simultaneously screed-coat, protective layer, insulating layer are set when, along far from post-cast strip 1 direction be insulating layer respectively, it is levelling
Layer, waterproof layer 3 and protective layer.
As can be seen from the above embodiments, water proof anti-seepage structure outside post-cast strip provided by the utility model has following excellent
Point:
1, post-cast strip position can realize timely backfill.
2, it can be used as the permanent formwork when concreting of post-cast strip using pile of building a wall outside, improve labor efficiency.
3, waterproof layer can be close to exterior wall and pier applies in time, and avoiding artificial truncation in the position, to form impervious leak thin
Weak-strong test.
4, post-cast strip is influenced by construction sequencing, and seaming position globality, water-resisting property etc. are relatively poor, builds one
The pier of uniform section and height dimension helps to improve the effect of anti-surrounding soil water pressure.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
