Description

Technical Field

[0001] The invention relates to the technical field of basement waterproof structures, and in particular to a bottom plate corner waterproof connection node and a construction method thereof. Background Art

[0002] For the waterproof structure at the bottom of the basement floor, the polymer self-adhesive film is more commonly used, while for the waterproof structure of the basement side wall, the SBS modified asphalt waterproof membrane is more commonly used. At the corner of the basement floor and the side wall, there is a connection condition between the SBS modified asphalt waterproof membrane on the side wall and the polymer self-adhesive membrane turned up from the bottom of the floor. SBS modified asphalt waterproof membrane is usually connected by hot melt, but because the heat resistance of the polymer self-adhesive membrane is lower than that of SBS modified asphalt waterproof membrane, when the SBS modified asphalt waterproof membrane is baked with a torch to a molten state on the surface and pasted on the polymer self-adhesive film, the lower polymer self-adhesive film will be instantly melted, and the waterproof material will be damaged.

[0003] Therefore, at present, SBS modified asphalt waterproof membrane is mostly overlapped with polymer self-adhesive membrane, or there is no connection between the two materials. This makes the quality of the connection nodes of the two waterproof membranes extremely poor, seriously affecting the waterproof effect. The external water of the basement side wall can easily penetrate through the two materials to the inside of the waterproof material, causing the risk of water seepage in the side wall. Summary of the invention

[0047] Combine the following Figure 1 , Figure 2 , describing an embodiment of the present invention.

[0048] According to an embodiment of the present invention, on the one hand, a bottom plate corner waterproof connection node is provided, such as Figure 1 As shown, it includes: a bottom plate 1, a side wall 2, a first waterproof membrane material 3 and a second waterproof membrane material 4.

[0049] The side wall 2 is arranged on the bottom plate 1; the first waterproof membrane material 3 is attached to the bottom plate 1; the second waterproof membrane material 4 is attached to the side wall 2, the hot melting temperature of the second waterproof membrane material 4 is higher than the hot melting temperature of the first waterproof membrane material 3, and at least part of the second waterproof membrane material 4 is connected to the first waterproof membrane material 3; wherein the first waterproof membrane material 3 is suitable for micro-heating and the micro-heating temperature does not exceed the hot melting temperature of the first waterproof membrane material 3, and the second waterproof membrane material 4 is suitable for hot-melt treatment so that the first waterproof membrane material 3 and the second waterproof membrane material 4 are fitted and connected.

[0050] In the above embodiment, the first waterproof membrane material 3 is slightly heated to a temperature not exceeding the hot-melt temperature of the first waterproof membrane material 3, and the second waterproof membrane material 4 is hot-melt treated, so that the membrane structure of the second waterproof membrane material 4 will not be destroyed when the second waterproof membrane material 4 is bonded and connected to the first waterproof membrane material 3, and the waterproof quality of the bonded connection between the first waterproof membrane material 3 and the second waterproof membrane material 4 is ensured, and the waterproof effect of the corner position of the bottom plate is improved, thereby solving the problem that the connection between two waterproof membrane materials with large differences in heat resistance is prone to water seepage.

[0051] Specifically, Figure 1 As shown, the bottom plate corner waterproof connection node provided in this embodiment is generally suitable for basement locations.

[0052] Furthermore, if Figure 1 As shown, the first waterproof membrane material 3 and the second waterproof membrane material 4 can be specifically made of polyvinyl chloride (PVC) membrane material, thermoplastic polyolefin (TPO) membrane material, high-density polyethylene (HDPE) membrane material, polytetrafluoroethylene (PTFE) membrane material, ethylene propylene diene monomer (EPDM) membrane material, etc. Among them, the first waterproof membrane material 3 is made of the one with a lower hot-melt temperature, and the second waterproof membrane material 4 is made of the one with a lower hot-melt temperature.

[0063] Specifically, Figure 1As shown, the width of the first waterproof membrane material 3 and the second waterproof membrane material 4 connected together can also be 255 mm, 260 mm, etc.

[0064] In some embodiments, Figure 1 As shown, the lower surface of the first waterproof membrane material 3 and the upper surface of the base plate 1 are bonded together using an adhesive tape 5 .

[0065] In the above embodiment, the first waterproof membrane 3 is folded to the upper surface of the base plate 1, and the lower surface of the first waterproof membrane 3 and the upper surface of the base plate 1 are adhered with tape 5 to ensure a stable connection between the first waterproof membrane 3 and the base plate 1.

[0066] Specifically, Figure 1 As shown, the adhesive tape 5 is provided as a butyl adhesive tape.

[0071] In some embodiments, Figure 1 As shown, the additional waterproof layer 6 is located at the junction of the bottom plate 1 and the side wall 2 .

[0072] Specifically, Figure 1 As shown, the additional waterproof layer 6 is bent at the junction of the bottom plate 1 and the side wall 2, and one side of the additional waterproof layer 6 close to the bottom plate 1 is folded above the bottom plate 1, and the width of the folded part is 250 mm.
