Construction device and construction method of SBS waterproofing membrane with composite non-curing coating

Abstract

This invention relates to the field of building waterproofing materials technology, specifically to a construction device and method for SBS waterproof membrane with a composite non-curing coating. The device is used for constructing SBS waterproof membrane with a composite non-curing coating. The waterproof membrane consists of a membrane body, a coating layer, and a release liner. The device includes a frame on which a membrane roller, a compaction roller, and a recovery roller are rotatably mounted. Before hot-melt construction of the SBS waterproof membrane, this invention removes a certain width of the non-curing rubber asphalt waterproof coating layer from one side of the membrane. The removed portion forms an overlap area, while the remaining portion forms a waterproof area that is hot-melted with the surface of the processing area. During the movement of the hot-melt membrane paving vehicle, when the overlap area covers the already constructed waterproof area and is hot-melted, a strong, dense, and fully asphalt-fused "body weld" is formed. Its strength and reliability are equal to or even better than the overlap of pure SBS membrane, eliminating the uncertainty caused by coating interlayers.

Description

Technical Field

[0001] This invention relates to the field of building waterproofing materials technology, specifically to an SBS waterproof membrane construction device and construction method with a composite non-curing coating. Background Technology

[0002] The combined use of SBS modified bitumen waterproof membrane and non-curing rubber bitumen waterproof coating can form an excellent waterproof layer that combines rigidity and flexibility. Traditional "coating + membrane" composite processes typically involve on-site, step-by-step application, or pre-laying with a full coat of non-curing coating on the back of the membrane. However, membranes fully coated with non-curing coating face serious problems during overlap: when both rolls are coated with non-curing coating, the coating is prone to overheating and flowing during the overlap heat fusion process, or overflowing excessively due to compression. This results in insufficient effective coating adhesion in the overlap area, creating a weak and uncontrollable interlayer, severely affecting the reliability of the overlap seal.

[0003] Therefore, while existing full-coat lamination methods simplify large-area application, they introduce new quality risks at the most critical overlap points. How to retain the advantages of non-curing coatings for large-area adhesion while ensuring a firm seal at the overlap edges has become a pressing technical challenge in this field.

[0004] The information disclosed in the background section is only intended to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects of existing composite membranes with fully coated non-curing coatings in the treatment of overlapping edges, and to provide a novel construction device and method for composite SBS waterproof membranes. This technical solution creates an overlapping area by removing one side of the coating layer of the SBS waterproof membrane. While ensuring full adhesion over a large area, it creates a clean and reliable direct heat-melt bonding area for the overlapping edge, thereby optimizing the waterproof performance of the entire area.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a construction device for SBS waterproof membrane with composite non-curing coating, used for the construction of SBS waterproof membrane with composite non-curing coating. The waterproof membrane consists of a membrane body, a coating layer, and a release liner. The device includes a frame, on which a membrane roller, a compaction roller, and a recovery roller are rotatably mounted. The waterproof membrane is wound and mounted on the membrane roller. The membrane body and the coating layer are pressed onto the surface of the processing area by the compaction roller. The release liner is wound and mounted on the recovery roller. A drive roller is rotatably mounted on the frame. A cutting element is mounted on the drive roller to cut the coating layer into a layer to be cut and a grounding layer. A cutting blade is mounted on the frame to cut the layer to be cut and the membrane body. The membrane body and the grounding layer form a waterproof area on the surface of the processing area. The portion of the membrane body from which the layer to be cut is removed forms an overlap area. When the overlap area is covered by hot-melt welding over the constructed waterproof area, a body weld seam is formed. Simultaneously, the two contacting waterproof areas are hot-melt welded to form a lateral adhesive seal.

[0007] Preferably, when the layer to be cut is cut from one side of the roll body by the cutting blade, the layer to be cut and the release film are wound together on the recycling roller.

[0008] Preferably, a guide roller is also rotatably mounted on the frame, and the guide roller and the compaction roller are symmetrically mounted on both sides of the cutting blade.

[0009] Preferably, the release film is not directly wound and connected to the roll roll, but is first rolled and connected to the outer peripheral surface of the guide roller, and then wound and connected to the roll roll. The compaction roller and the guide roller are respectively rolled and connected to the roll body and the release film.

[0010] Preferably, the cutting component cuts the release film while cutting the coating layer, cutting the release film into an anti-stick film and a recycling film. The layer to be cut and the roll roll are both attached to the anti-stick film. The layer to be cut and the anti-stick film are wound on the recycling roll to form a recycling roll. The grounding layer and the roll roll are both attached to the recycling film. The recycling film is wound on the recycling roll.

[0011] Preferably, the cutting component includes a disc fixedly mounted on the transmission roller, and an annular cutter fixedly mounted on the outer circumferential surface of the disc. The annular cutter cuts the coating layer into the layer to be cut and the grounding layer, and cuts the separator into an anti-sticking film and a recycling film.

[0012] Preferably, a limiting roller that is rotatably mounted on the frame and fits against the outer peripheral surface of the roll body is also provided, and the outer peripheral surface of the disc and the outer peripheral surface of the limiting roller are respectively in contact with the surface of the roll body and the surface of the release film.

[0013] Preferably, the disc is axially slidably connected to the drive roller, and both the disc and the frame are equipped with threaded fasteners for locking the drive roller and the cutting blade.

[0014] Preferably, the compaction roller and the transmission roller are fixedly mounted with first transmission wheels at their ends, and two first transmission wheels are mounted with first gear belts. The roll roller and the recycling roller are both fixedly mounted with second transmission wheels at their ends, and two second transmission wheels are mounted with second gear belts.

[0015] Secondly, the present invention also provides a construction method for operating the SBS waterproof membrane construction device with the composite non-curing coating for construction, comprising the following steps:

[0016] S1: Move the hot melt membrane paving vehicle to one side of the already laid waterproof membrane, and then use the hot melt membrane paving vehicle to drag the frame to move, so that the overlapping area of ​​one waterproof membrane covers the waterproof area of ​​another waterproof membrane.

[0017] S2: Perform hot-melt construction on the overlapping area to fuse the two waterproof membranes together to form a welded seam.

[0018] S3: The non-cured coating layers on both sides of the weld seam of the main body are bonded to the edge of the weld seam to form a composite sealing structure.

[0019] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0020] 1. Before hot-melt construction of SBS waterproof membrane, this invention removes a certain width of the non-cured rubber asphalt waterproof coating layer on one side of the waterproof membrane. The removed portion forms an overlap area, while the unremoved portion forms a waterproof area that is hot-melted with the surface of the processing area. As the hot-melt membrane paving vehicle moves, when the overlap area covers the already constructed waterproof area and is hot-melted and welded, a strong, dense, and fully asphalt-fused "body weld" is formed. Its strength and reliability are equal to or even better than the overlap of pure SBS membrane, eliminating the uncertainty caused by coating interlayer.

[0021] 2. Simultaneously, after the hot-melt welding of the overlapping area and the waterproof area in this invention is completed, the coating layers adjacent to both sides of the weld seam will slightly soften under the influence of heat, forming excellent lateral adhesion and sealing with the edge of the weld seam. These two thick non-curing coating layers act like "dams," providing additional flexible protection and a moisture barrier for the weld seam. The entire node forms a composite waterproof structure of "internal robust body weld seam + flexible non-curing reinforcing strips on both sides";

[0022] 3. The present invention first uses a cutting tool to cut the coating layer into a layer to be cut and a grounding layer, and then uses a cutting knife to cut the layer to be cut from the roll body, so that the device can be directly used on existing composite non-curing coating SBS waterproof rolls to solve the problem of coating overflow in the overlap area, resulting in insufficient actual effective bonding of coating in the overlap area, which instead forms a weak and uncontrollable interlayer, seriously affecting the reliability of the overlap seal.

[0023] 4. At the same time, when recycling the cut-off layer, this invention does not use cumbersome parts or additional structures. Instead, it adds a guide roller and changes the timing of the separation of the release film from the roll body, cutting the release film into an anti-stick film and a recycling film. The anti-stick film is used to rewind the removed layer onto the recycling roller to form a recycling roll. This facilitates later recycling and can also effectively prevent the coating layer from adhering to the cut parts and the guide roller, thus avoiding affecting the laying quality of the waterproof roll.

[0034] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0036] This invention provides, for example Figure 1-7 The diagram illustrates an application device for SBS waterproof membrane with a composite non-curing coating. This device is used to apply the composite non-curing coating to the flat surface of a processing area. The composite non-curing coating consists of three parts: an SBS modified bitumen waterproof membrane body 1, a non-curing rubber bitumen waterproof coating layer 2 applied to the side of the SBS modified bitumen waterproof membrane body 1 facing the processing area during application, and a release film 3 covering the surface of the non-curing rubber bitumen waterproof coating layer 2. Existing application devices for laying waterproof membranes are generally hot-melt membrane pavers, including a frame 4. A membrane roll 5, a compaction roll 6, and a recovery roll 7 are rotatably mounted on the frame 4. The waterproof membrane is wound and installed on the membrane roll 5. As the hot-melt membrane paving vehicle moves forward, the release film 3 on the waterproof membrane separates from the coating layer 2 and is directly wound onto the recycling roller 7. The membrane body 1 with the coating layer 2 is pressed onto the ground by the compaction roller 6 for hot melting. The coating layer 2 softens after hot melting and adheres to the surface of the processing area. However, the membrane body 1 fully coated with the non-curing rubber asphalt waterproof coating layer 2 faces a serious problem when overlapping: when both overlapping edges of the membrane body 1 are coated with the non-curing rubber asphalt waterproof coating layer 2, the rubber asphalt coating is very prone to flow due to excessive heat or overflow in large quantities due to compression during the hot melting process of overlapping. This results in insufficient amount of coating effectively bonded in the overlapping area 12, instead forming a weak and uncontrollable interlayer, which seriously affects the reliability of the overlapping seal.

[0037] To this end, a drive roller 8 is rotatably mounted on the frame 4, and a disc 901 is slidably mounted on the drive roller 8. An annular cutter 902 is fixedly mounted on the outer circumference of the disc 901. A threaded fastener is also mounted on the disc 901 to lock the drive roller 8. Here, the annular cutter 902 and the disc 901 constitute the cutting element 9. Simultaneously, a cutting blade 10 is slidably mounted on the frame 4, and a threaded fastener is also mounted on the frame 4 to lock the cutting blade 10. Loosening the threaded fastener allows adjustment of the positions of the cutting blade 10 and the annular cutter 902 as needed. Thus, when the waterproof membrane unfolds from the roll roll 5, the release film 3 first separates from the coating layer 2 and winds onto the recovery roller 7. Then, as the roll body 1 and the coating layer 2 are pressed onto the processing surface by the compaction roller 6, the drive roller 8 first drives the disc 901 to rotate, and the disc 901 drives the annular cutter 902 to rotate, thereby removing the coating layer... 2. The material is cut into a layer to be cut 201 and a grounding layer 202. Before the layer to be cut 201 comes into contact with the construction surface, the layer to be cut 201 and the roll body 1 move toward the cutting blade 10, so that the cutting blade 10 cuts the layer to be cut 201 from the roll body 1. In this way, when the compaction roller 6 presses the roll body 1 and the grounding layer 202 onto the surface of the processing area, a waterproof area 11 is formed. The part of the roll body 1 from which the layer to be cut 201 is removed forms an overlap area 12. When the overlap area 12 covers the surface of the already constructed waterproof area 11 and is hot-melted welded, a strong, dense, and fully asphalt-fused "body weld seam" is formed. Its strength and reliability are equal to or even better than the overlap of pure SBS roll material, eliminating the uncertainty caused by the coating interlayer. At the same time, after the hot-melt welding is completed, the coating layer 2 on both sides of the weld seam will slightly soften under the influence of heat, forming excellent lateral adhesion and sealing with the edge of the weld seam. Meanwhile, these two thick, non-curing coating layers act like "dams," providing additional flexible protection and a moisture barrier for the weld joint. The entire node forms a composite waterproof structure consisting of an internally robust weld joint and flexible, non-curing reinforcing strips on both sides.

[0038] Furthermore, in order to improve the cutting effect of the cutting blade 10 on the coating layer 2, we rotatably install a limiting roller 15 and a guide roller 13 on the frame 4. The limiting roller 15 and the disc 901 together roll and connect the coil body 1 and the coating layer 2 to ensure that the cutting blade 10 can accurately cut the coating layer 2 into the layer to be cut 201 and the ground layer 202. The guide roller 13 also contacts the coating layer 2 and works with the compaction roller 6 to help the cutting blade 10 better remove the layer to be cut 201 from the coil body 1.

[0039] Furthermore, due to the adhesive nature of the non-curing rubber asphalt waterproof coating layer 2, adhesion problems exist on the disc 901 and guide roller 13. With increased usage time, a rubber asphalt ring of a certain thickness will form, affecting the cutting effect of the annular cutter 902 and the cutting blade 10. Simultaneously, if the layer to be cut 201 is not removed promptly after being removed by the cutting blade 10, as the hot-melt membrane paving vehicle moves, this removed layer 201 will eventually be pressed between the waterproof membrane and the processing area surface by the compaction roller 6, affecting the construction effect. Therefore, instead of directly tearing the release film 3 from the coating layer 2 and then winding it onto the recovery roller 7 when the waterproof membrane is unrolled, we allow the release film 3 to move along with the coating layer 2 into the space between the limiting roller 15 and the disc 901 after the waterproof membrane is unrolled. The release film 3 then separates the coating layer 2 from the disc 901. 01. Isolation is performed so that the annular cutter 902 simultaneously cuts the isolation membrane 3 into an anti-sticking membrane 301 and a recycling membrane 302. The anti-sticking membrane 301 is bonded to the layer to be cut 201, and the recycling membrane 302 is bonded to the grounding layer 202. Then, the anti-sticking membrane 301 and the recycling membrane 302 come into contact with the outer peripheral surface of the guide roller 13. The anti-sticking membrane 301 isolates the coating layer 2 and the guide roller 13. When the cutter cuts the layer to be cut 201 from the waterproof membrane, we do not set up a separate device structure to recycle the layer to be cut 201. Instead, we use the anti-sticking membrane 301 to let the layer to be cut 201 and the anti-sticking membrane 301 be wound together on the recycling roller 7 to form a recycling roll 14. Similarly, the anti-sticking membrane 301 will separate the layer to be cut 201 and the recycling roller 7, so that the recycling roll 14 can be directly removed from the recycling roller 7 later, which facilitates the recycling of the rubber asphalt that constitutes the layer to be cut 201.

[0040] Furthermore, the compaction roller 6 and the drive roller 8 are fixedly equipped with first drive wheels 16, and first gear belts 17 are installed on the two first drive wheels 16. The roll material roller 5 and the recovery roller 7 are both fixedly equipped with second drive wheels 18, and second gear belts 19 are installed on the two second drive wheels 18. In this way, as the hot melt roll material paving vehicle moves, the compaction roller 6 will not only automatically press the grounding layer 202 onto the surface of the processing area, but also drive the drive roller 8 to rotate through the cooperation of the first drive teeth and the first gear belt 17, so that the drive roller 8 rotates and cuts against the direction of travel of the coating layer 2. At the same time, when the waterproof roll material on the roll material roller 5 is unrolled, the roll material roller 5 will drive the recovery roller 7 to rotate through the second drive wheels 18 and the second gear belt 19, so that the layer to be cut 201 and the anti-stick film 301 form a recovery roll 14 on the recovery roller 7, and the recovery film 302 is wound on the recovery roller 7.

[0041] This invention also provides a construction method for using an application device for SBS waterproof membrane with a composite non-curing coating. The method includes the following steps:

[0042] S1: Move the hot melt membrane paving vehicle to one side of the already laid waterproof membrane, and then use the hot melt membrane paving vehicle to drag the frame to move, so that the overlap area 12 of one waterproof membrane covers the waterproof area 11 of another waterproof membrane.

[0043] S2: Perform hot-melt construction on the overlapping area to fuse the membrane bodies 1 of the two waterproof membranes to form a body weld seam;

[0044] S3: The non-cured coating layer 2 on both sides of the weld seam of the main body is bonded to the edge of the weld seam to form a composite sealing structure.
