Referring to fig. 1 to 5, the preferred embodiment of the present invention is shown.

A waterproof roll with salient points on two sides comprises a waterproof layer, wherein the waterproof layer comprises an upper bonding layer 25 and a lower bonding layer 26, and the upper bonding layer 25 and the lower bonding layer 26 are integrally formed; a plurality of upper protruding strips 21 are formed on the upper adhesive layer 25 in a direction away from the upper adhesive layer 25, and a plurality of lower protruding strips 22 are formed on the lower adhesive layer 26 in a direction away from the lower adhesive layer 26; the upper protruding strips 21 are arranged in a quincunx on the upper adhesive layer 25, and the lower protruding strips 22 are arranged in a quincunx on the lower adhesive layer 26.

Above-mentioned waterproof coiled material of a both sides area bump that provides, in laying waterproof coiled material 10 in-process, lower protruding strip 22 on waterproof coiled material 10's lower tie coat 26 imbeds in the concrete thick liquid 30 of lower part, after concrete thick liquid 30 of lower part solidifies, pour into concrete thick liquid 30 above waterproof coiled material 10, after concrete thick liquid 30 of waterproof coiled material 10 top solidifies, realize the water-proof treatment to the basement structure promptly, at this moment, it imbeds respectively in the concrete with lower protruding strip 21 to go up protruding strip 21 and lower protruding strip 22, on the one hand, the area of contact between waterproof coiled material 10 and the concrete has been increased, stability between waterproof coiled material 10 and the concrete has been increased, on the other hand, under the restriction of last protruding strip 21 and lower protruding strip 22, waterproof coiled material 10 is difficult for taking place to rock, the displacement, thereby strengthen waterproof coiled material 10's stability, waterproof coiled material 10's waterproof performance is promoted, has strong practicability.

Moreover, compared with the square arrangement, the quincunx arrangement can enable the stress of the upper protruding strips 21 and the lower protruding strips 22 to be more uniform, and the integrity is stronger.

The quincunx arrangement is the arrangement like the plum blossom petal, and is mostly in a five-point arrangement form.

Moreover, upper protruding strip 21 and lower protruding strip 22 are the mirror image and arrange, fix, spacing waterproofing membrane 10 from upper and lower two directions, and the application of force is more even.

In another embodiment, the upper protruding strips 21 and the lower protruding strips 22 are arranged in a staggered manner, so that a larger area of the waterproof roll 10 is covered, and blind areas are reduced.

Specifically, go up protruding strip 21 and last tie coat 25 and arrange perpendicularly, protruding strip 22 is arranged perpendicularly with lower tie coat 26 down, be convenient for more concrete thick liquid 30 and go up protruding strip 21 and fill between the protruding strip 22 down, mix, simultaneously, come the analysis from atress angle direction, relative waterproofing membrane 10 is the last protruding strip 21 of arranging perpendicularly and also can receive the bigger power of holding from concrete thick liquid 30 with protruding strip 22 down, and then play better spacing, fixed effect to waterproofing membrane 10.

In order to further increase the contact area between the upper and lower protruding strips 21, 22 and the concrete grout 30, a plurality of protruding blocks 210 are disposed on the outer side wall of the upper protruding strip 21 and the outer side wall of the lower protruding strip 22, and the plurality of protruding blocks 210 are uniformly distributed on the outer side wall of the upper protruding strip 21 and the outer side wall of the lower protruding strip 22, that is, around the outer side wall of the upper protruding strip 21 and the outer periphery of the lower protruding strip 22, and are distributed over the outer side wall of the upper protruding strip 21 and the outer periphery of the lower protruding strip 22 and arranged in an empty manner.

The tail end of the protruding block 210 is also provided with an expanded part 220, the edge part of the expanded part 220 extends towards the direction departing from the protruding block 210 and is arranged in parallel with the waterproof layer, and the protruding block 210 is combined with the concrete grout 30 more tightly and is not easy to separate from the concrete grout 30.

The bump 210 and the expansion part 220 are integrally formed and arranged, so that the consistency and the integrity are better.

Go up tie coat 25 and tie coat 26 down and be the unevenness form and arrange, further promote the frictional force on waterproofing membrane 10 surface, be convenient for concrete grout 30 to last tie coat 25 and tie coat 26 adhesion down.

Furthermore, the outer surface of the upper bonding layer 25 and the outer surface of the lower bonding layer 26 are also provided with bonding, and the adhesive can be made of high polymer resin and high quality asphalt as base materials and polyethylene film and aluminum foil as surface materials.

The main body layer is arranged between the upper bonding layer 25 and the lower bonding layer 26 and is made of polyethylene polypropylene, and the polyethylene polypropylene has the advantages of high tensile strength, strong impermeability, good low-temperature flexibility, small expansion coefficient, low temperature rise effect, strong deformation adaptability and large friction coefficient.

The limit portion of waterproof layer is provided with overlap joint portion 50, does not set up protruding strip 21 and protruding strip 22 down on the overlap joint portion 50, like this, when single waterproof layer can't satisfy the needs of construction area, can carry out the overlap joint combination to a plurality of waterproof layers through overlap joint portion 50, because do not set up protruding strip 21 and protruding strip 22 down on the overlap joint portion 50, consequently can not disturb the mutual overlap joint between a plurality of waterproof layers.

In order to facilitate the overlap joint between two waterproof layers, be provided with the depressed area on overlap joint portion 50 to the orientation opposite direction of the depressed area of the 50 overlap joint portions of mutual arrangement, like this, when single waterproof layer can't satisfy the needs of the regional area of construction, two adjacent waterproof layers imbed each other, and connect through rubber coating or hot melt method between two overlap joint portions 50, and the junction can not rise the perk, and is more level and smooth, the construction of being convenient for.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
