Description

Technical Field

[0001] This utility model relates to the field of waterproof engineering construction technology, and in particular to a device for laying and compacting R-angle waterproof membrane. Background Technology

[0002] In order to improve the waterproofing effect and prevent the waterproof membrane from cracking and leaking at the inside corners during the construction of existing waterproofing projects, it is generally necessary to make a rounded corner at the inside corner of the foundation.

[0003] Based on existing technology and engineering practice, it has been found that during waterproofing construction, the waterproofing membrane at the rounded corners of the foundation cannot be tightly adhered, resulting in air pockets in the membrane at the rounded corners. This has become a common problem affecting the quality of waterproofing construction. Regardless of whether self-adhesive or wet-laying methods are used, the existing waterproofing membrane laying and compaction devices cannot effectively compact the waterproofing membrane at the rounded corners. As a result, air and moisture between the upper and lower layers of membrane also affect the density of the membrane laying at the rounded corners, thus affecting the quality of waterproofing construction.

[0004] To address the aforementioned issues, a portable waterproof membrane compaction device is proposed. This device can compact the waterproof membrane at the radius (R) corner of the foundation cap without requiring electricity, thereby improving the quality of waterproofing construction. Utility Model Content

[0005] The purpose of this utility model is to provide a device for laying and compacting R-corner waterproof membrane. It has a simple structure, is easy to carry, and can compact the R-corner waterproof membrane of the foundation, thereby improving the quality of waterproof construction.

[0006] To solve the above-mentioned technical problems, the embodiments of this utility model provide a technical solution as follows:

[0007] A device for laying and compacting R-angle waterproof membrane includes a handrail and a support frame that is detachably and fixedly connected to the handrail. The support frame is rotatably connected to a pressure roller. The pressure roller has a circular cross-sectional profile, and the diameter of the cross-sectional profile increases from both ends to the middle.

[0008] Furthermore, the support frame includes a support crossbar, and connecting arms extend from both ends of the support crossbar in the same direction. The pressure roller is rotatably disposed between the two connecting arms.

[0009] Furthermore, the pressure roller includes a roller body and a roller shaft arranged along its central axis. Both ends of the roller shaft extend beyond the end face of the roller body. The free ends of the connecting arms are symmetrically provided with connecting holes, and both ends of the roller shaft pass through the connecting holes.

[0010] Furthermore, the connecting hole is a U-shaped opening, and the end of the roller shaft is fixedly connected to the connecting arm by fasteners.

[0011] Furthermore, the handrail includes a connecting rod connected to the support frame, and an adjusting rod that is rigidly and telescopically connected to the connecting rod.

[0012] Furthermore, the connecting rod is provided with a plurality of axially arranged adjustment holes, and the end of the adjusting rod facing the handrail is provided with a spring pin. The spring pin can be engaged with the adjustment holes to lock and prevent relative displacement between the adjusting rod and the connecting rod.

[0013] Furthermore, the support frame is provided with a connector in the center, and the handrail is threadedly connected to or snapped into the connector.

[0014] The R-corner waterproof membrane laying and compaction device provided by this utility model, compared with the prior art, through the rotational connection between the support frame and the pressure roller, and the cone-shaped setting where the diameter of the pressure roller's cross-section contour line gradually increases from both ends to the middle, allows the contact surface between the pressure roller and the waterproof membrane to better fit with the R-corner arc surface, improving the compaction effect of the R-corner waterproof membrane laying. The structure is simple, easy to carry, and can effectively address uneven R-corner surfaces, reducing the occurrence of inadequate compaction of the R-corner waterproof membrane, improving the tightness of the bond between the waterproof membrane and the R-corner, thereby enhancing the overall waterproofing effect.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0026] like Figure 1 As shown, in order to improve the waterproofing effect of the inside corner of the foundation 5, it is often necessary to add a rounded R-corner 6 at the inside corner, and then lay the waterproof membrane 7 at the R-corner 6 of the foundation 5 to increase the adhesion between the waterproof membrane 7 and the foundation 5 and improve the waterproofing performance.

[0027] like Figure 2-5As shown, one embodiment of this utility model relates to a device for laying and compacting a waterproof membrane 7 with an R-angle of 6, including a handrail 1 and a support frame 2 detachably and fixedly connected to the handrail 1. A pressure roller 3 is rotatably connected to the support frame 2. The pressure roller 3 has a circular cross-sectional profile, and the diameter of the cross-sectional profile increases sequentially from both ends towards the middle. Preferably, the pressure roller 3 includes a roller body 32 and a roller shaft 31 rotatably disposed at the central axis of the roller body 32. Both ends of the roller shaft 31 extend beyond the end faces of the roller body 32 and are fixedly connected to the support frame 2. By designing the diameter of the cross-section of the pressure roller 3 to gradually increase from both ends to the middle, compared to a conventional cylindrical pressure roller, the pressure roller 3 provided by this invention reduces the contact area between the pressure roller 3 and the waterproof membrane 7 when laying and pressing the R-angle 6 waterproof membrane 7. Under the same force applied to the roller body 32, the waterproof membrane 7 withstands greater pressure, which is beneficial for the waterproof membrane 7 to adhere firmly to the R-angle 6 surface. Since the R-angle 6 at the inside corner of the support platform 5 is mostly set later, its surface is arc-shaped, resulting in limited flatness and surface undulation. By designing the diameter of the cross-section of the pressure roller 3 provided by this invention to gradually increase from both ends to the middle, the surface undulation of the R-angle 6 can be effectively addressed, reducing the occurrence of inadequate laying and pressing of the R-angle 6 waterproof membrane 7, improving the tightness of the adhesion between the waterproof membrane 7 and the R-angle 6, and thus improving the overall waterproof effect.

[0028] like Figure 4-5 As shown, in an exemplary example, the roller body 32 is generally spindle-shaped, the outer contour of the cross-section of the roller body 32 is circular, and the diameter of its end face contour line 33 is smaller than the center contour line 34 at its center position. Preferably, the contour line of the axial section of the roller body 32 is a symmetrical figure composed of smooth arcs and straight lines.

[0029] like Figure 7-8 As shown, in one embodiment, a device for laying and compacting a waterproof membrane 7 with an R-angle of 6 is provided. The support frame 2 includes a support crossbar 22, with connecting arms 23 extending in the same direction at both ends of the support crossbar 22. The pressure roller 3 is rotatably disposed between the two connecting arms 23. A connector 21 is centrally located on the support frame 2, and the handrail 1 is threadedly connected to or snap-fitted to the connector 21.

[0030] In an exemplary example, the free end of the connecting arm 23 is symmetrically provided with connecting holes 24, and both ends of the roller shaft 31 pass through the connecting holes 24. Preferably, the connecting holes 24 are U-shaped openings, and the ends of the roller shaft 31 are fixedly connected to the connecting arm 23 by fasteners 4.

[0031] like Figure 6As shown, one embodiment relates to a device for laying and compacting a waterproof membrane 7 with an R-angle of 6. The handrail 1 includes a connecting rod 11 connected to a support frame 2, and an adjusting rod 12 rigidly and telescopically connected to the connecting rod 11. In an exemplary example, the connecting rod 11 has multiple axially arranged adjusting holes 111. The end of the adjusting rod 12 facing the handrail 1 has a spring pin 121, which engages with the adjusting holes 111 to lock and prevent relative displacement between the adjusting rod 12 and the connecting rod 11. In use, the end of the adjusting rod 12 with the spring pin 121 is inserted into the end of the connecting rod 11 away from the support frame 2. By aligning the spring pin 121 with different adjusting holes 111, the length of the handrail 1 can be adjusted. When it is necessary to disassemble or adjust the length of the handrail 1, pressing down the spring pin 121 allows the adjusting rod 12 to be displaced relative to the connecting rod 11 by pushing or pulling. Of course, the telescopic mechanism of the connecting rod 11 and the adjusting rod 12 can also be achieved using existing technology that involves setting a fixing buckle or adjusting ring between the adjusting rod 12 and the connecting rod 11, which will not be elaborated here. The telescopic adjusting rod 12 better meets the needs of different workers and different work spaces, while also being easy to disassemble and carry by workers.

[0032] The R-corner waterproof membrane laying and compaction device provided by this utility model, compared with the prior art, through the rotational connection between the support frame and the pressure roller, and the cone-shaped setting where the diameter of the pressure roller's cross-section contour line gradually increases from both ends to the middle, allows the contact surface between the pressure roller and the waterproof membrane to better fit with the R-corner arc surface, improving the compaction effect of the R-corner waterproof membrane laying. The structure is simple, easy to carry, and can effectively address uneven R-corner surfaces, reducing the occurrence of inadequate compaction of the R-corner waterproof membrane, improving the tightness of the bond between the waterproof membrane and the R-corner, thereby enhancing the overall waterproofing effect.

[0033] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
