Description

Technical Field

[0001] The invention relates to the technical field of self-adhesive waterproof coiled materials, in particular to a physical edge-locking self-adhesive waterproof coiled material. Background Art

[0002] Self-adhesive waterproof membrane is a special waterproof material, mainly used in building waterproofing projects. Multiple pieces of self-adhesive waterproof membrane are laid flat on the ground or roof, and the edges of the waterproof membrane are overlapped together. The overlapping part is usually called the "lap edge", and the "lap edge" of the waterproof membrane is coated with glue, so that the edges of multiple pieces of waterproof membrane are glued together by glue, and multiple pieces of waterproof membrane form a larger area of ​​waterproof layer; however, with long-term use, sunlight will continuously shine on a large area of ​​sticky waterproof membrane, coupled with the aging of glue at the adhesive position of the waterproof membrane, and the cracking of the ground, the overlapping edge joint of the membrane is easy to fall off and curling, and the cracking of the ground will also passively pull the waterproof membrane off.

[0003] The rolled waterproof membrane is easy to be further separated, so the separated waterproof membrane and the broken membrane cannot play a waterproof effect on the ground or the roof of the house.

[0004] The present invention is proposed in view of the above problems. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a physical locking edge self-adhesive waterproof membrane to solve the problems mentioned in the background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions.

[0007] The present invention provides a physical locking edge self-adhesive waterproofing roll material, comprising a roll material body, the roll material body is in a rectangular sheet shape, and two long side edges of the roll material body are respectively provided with an upper step cavity and a lower step cavity, the upper step cavity is located on the upper surface of the roll material body, and the lower step cavity is located on the lower surface of the roll material body. When a plurality of roll material bodies are flattened, the lower step cavity is just located above the upper step cavity;

[0008] The length, width and depth of the upper step cavity and the lower step cavity are consistent, and the upper step cavity and the lower step cavity can be tightly mortise and tenoned together. When multiple coil bodies are spliced, the visual effect is relatively flat and beautiful. The inner bottom surface of the upper step cavity is provided with two card grooves, and the inner top surface of the lower step cavity is provided with two card strips;

[0009] The card slot is arranged along the length direction of the upper step cavity, and the card strip is arranged along the length direction of the lower step cavity;

[0010] When the lower step cavity of one coil body is fitted with the upper step cavity of another coil body, the card strip is snapped into the card slot. By snapping the card strip into the card slot, multiple flat coil bodies can be connected together more firmly. The two sets of card strips and card slots are snapped into each other, which can generate a strong connection force, making up for the deficiency of the existing waterproof self-adhesive coil overlap relying only on chemical bonding, and at the same time increasing the physical bite overlap of the overlapped edges of the coils.

[0011] When the lower step cavity of one coil body and the upper step cavity of another coil body are engaged in a complementary manner, the clamping strip is clamped in the clamping groove to form a mortise and tenon structure engagement.

[0012] Preferably, the two clamping grooves are evenly distributed along the width direction of the upper step cavity at equal intervals, and the two clamping strips are evenly distributed along the width direction of the lower step cavity at equal intervals.

[0013] Preferably, the cross-sections of the card slot and the card strip are both rectangular, and the outer wall of the card strip is interference fit with the inner wall of the card slot.

[0014] Preferably, the cross-sectional heads of the card slot and the card strip are both heart-shaped, the widest position of the horizontal cross-sectional area of ​​the card slot is located at the mouth of the card slot, and the widest position of the horizontal cross-sectional area of ​​the card strip is located at the root of the card strip, so that the card strip can enter the card slot in a more conical manner, and the outer wall of the card strip and the inner wall of the card slot have an interference fit.

[0015] Preferably, the cross-sections of the card slot and are respectively concave, and the cross-sections of the card strip and are respectively convex; the card slot corresponds to the card strip, and the card slot corresponds to the interference fit between the upper and lower outer walls and inner walls of the card strip.

[0016] Preferably, the upper adhesive plane and the lower adhesive plane on the adhesive surface are chemically bonded and interference fit.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The length, width and depth of the upper step cavity and the lower step cavity are consistent, and the lower step cavity of one coil body can just be located in the upper step cavity of another coil body with interference fit. In this way, multiple coil bodies can be spliced ​​together more firmly;

[0019] When the lower step cavity of one roll body can just be located in the upper step cavity of another roll body, the two card strips can be respectively embedded in their corresponding card slots, and the plane overlap between the two card slots retains the original self-adhesive glue, that is, the chemical bonding of the overlapping edges of the waterproof self-adhesive rolls under the existing background is retained, while the physical mortise and tenon overlap of the overlapping edges of the rolls is increased.

[0020] The upper step cavity and the lower step cavity of multiple coil bodies can be spliced ​​together by the mortise and tenon joint of the card strip and the card slot, and the splicing is relatively firm, and can resist the curling or passive tearing of the coil body caused by sunlight and ground cracks for a long time;

[0021] Even with the exposure to sunlight and aging of the glue, the multiple roll bodies can still be firmly connected together because the card strips are firmly connected to the card slots. They can exist in an overall large-area shape for a long time, so as to play the role of ground waterproofing or roof waterproofing for a long time. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] like Figure 1-4As shown, a physical locking edge bite self-adhesive waterproofing roll material comprises a roll material body 1, the roll material body 1 is a sheet-like rectangular shape, so that a plurality of roll material bodies 1 can be flatly spread out in a plane, and the two long side edges of the roll material body 1 are respectively provided with an upper step cavity 11 and a lower step cavity 14, an upper step cavity 12 and a lower step cavity 13, the upper step cavity 11 is located on the upper surface of the roll material body 1, the lower step cavity 14 is located on the lower surface of the roll material body 1, the upper step cavity 12 is located on the upper surface of the roll material body 1, and the lower step cavity 13 is located on the lower surface of the roll material body 1, and when a plurality of roll material bodies 1 are flatly spread out, the lower step cavity 11 is just located above the upper step cavity 14, and the lower step cavity 12 is just located above the upper step cavity 13;

[0030] The length, width and depth of the upper step cavity 11 and the lower step cavity 14 are consistent, and the length, width and depth of the upper step cavity 12 and the lower step cavity 13 are consistent, so that the upper step cavity 11 and the lower step cavity 14 can fit tightly together, and the upper step cavity 12 and the lower step cavity 13 can fit tightly together with mortise and tenon joints. When multiple coil bodies 1 are spliced, the visual effect is relatively flat and beautiful, and the function is sturdy and durable.

[0031] The upper adhesive plane 9 between the card strips and the lower adhesive plane 10 between the card slots are chemically bonded and interference fit. The visual effect is relatively flat and beautiful, and the function is dense and solid;

[0032] The two clamping grooves 13 are evenly distributed along the width direction of the upper step cavity 11 at equal intervals, and the two clamping strips 14 are evenly distributed along the width direction of the lower step cavity 12 at equal intervals.

[0033] The cross sections of the clamping slot 13 and the clamping strip 14 are both rectangular, and the outer wall of the clamping strip 14 is interference-fitted with the inner wall of the clamping slot 13 .

[0034] The cross-sections of the slot 13 and the strip 14 are both semi-elliptical. The widest position of the slot 13 in horizontal cross-section is located at the mouth of the slot 13 , and the widest position of the strip 14 in horizontal cross-section is located at the root of the strip 14 . The outer wall of the strip 14 and the inner wall of the slot 13 are interference fit.

[0035] The cross sections of the card slots 11 and 13 are both "concave" shaped, and the cross sections of the card strips 12 and 14 are both "convex" shaped; the card slot 11 corresponds to the card strip 14, and the card slot 12 corresponds to the card strip 13, with interference fit between the upper and lower outer walls and inner walls.

[0036] A chemically bonded interference fit is formed between the upper bonding plane 9 and the lower bonding plane 10 on the bonding surface.

[0037] In summary: the length, width and depth of the upper step cavity 11 and the lower step cavity 12 are consistent, the lower step cavity 12 of one coil body 1 can just be located in the upper step cavity 11 of another coil body 1, and the inner bottom surface of the upper step cavity 11 and the inner top surface of the lower step cavity 12 are coated with glue, so that the upper step cavity 11 and the lower step cavity 12 can be glued together by glue, so that multiple coil bodies 1 are spliced ​​together;

[0038] When the lower step cavity 12 of one coil body 1 can be just located in the upper step cavity 11 of the other coil body 1, the two clamping strips 14 can be embedded in the clamping groove 13, the glue on the inner bottom surface of the upper step cavity 11 can enter the clamping groove 13, and the glue on the inner top surface of the lower step cavity 12 can cover the surface of the clamping strip 14, so that when the clamping strip 14 is clamped in the clamping groove 13, there is not only friction generated by the clamping, but also adhesion generated by the glue adhesion between the clamping strip 14 and the clamping groove 13;

[0039] By means of the clamping of the clamping strip 14 and the clamping slot 13 and the gluing, the upper step cavity 11 and the lower step cavity 12 of the plurality of coil bodies 1 can be spliced ​​together, and the splicing is relatively firm, and can resist the curling or tearing of the coil body 1 caused by sunlight and ground cracks for a long time;

[0040] Even with sunlight exposure and aging of the glue, since the card strip 14 is firmly clamped in the card slot 13, the multiple roll bodies 1 can still be firmly connected together and can exist in an overall large-area shape for a long time, so as to exert the effect of ground waterproofing or roof waterproofing for a long time.
