Description

Technical Field

[0001] This invention relates to the technical field of edge sealing and installation, and specifically to an apparatus and method for edge sealing and installation of waterproof membrane rolls. Background Technology

[0002] Generally, the following measures are taken when sealing the edges of waterproof membrane in winter:

[0003] (1) Material protection requirements and measures: In order to prevent rain and snow from covering the waterproof materials, the waterproof materials are piled up in a centralized manner and the finished products are protected with tarpaulins, etc. The unused waterproof materials are collected on site and collected before the end of the work, and covered with tarpaulins or straw curtains for protection, which is very troublesome.

[0004] (2) The overlap of the roll material is bonded with adhesive layer to adhesive layer. Generally, heating equipment is used to assist in heat treatment. Specifically, it is a two-person construction. One person holds a flame sprayer to spray flames at the overlap, and the other person rolls it. Since two people are required to work, it wastes human resources. At the same time, the person spraying the flame needs to bend over for a long time, which is very harmful to the worker's body.

[0005] (3) Since the overlapping area is usually not a limited area, it includes long distances and wide areas, and such long overlapping areas require higher standards from workers.

[0006] In fact, if a construction machine and method existed that could easily and reliably complete winter construction or long-distance construction, it would save labor and reduce the difficulty of protecting materials. Summary of the Invention

[0007] To address the problems existing in the prior art, this invention provides a waterproof membrane edge sealing and laying device. This device features a dual-mode laying mechanism with both mobile and laying states. In laying state, a single person can efficiently complete the waterproof membrane edge sealing and laying work in a short time, with minimal air bubbles and wrinkles. In mobile state, the device is easy to move, and unused waterproof membrane is placed on it for easy storage by workers, reducing the time spent on material collection. Operation is simple and requires minimal worker skill. Another objective of this invention is to provide a waterproof membrane edge sealing and laying method, thereby further improving the reliability and stability of the waterproof membrane edge sealing and laying device.

[0008] To achieve the above objectives, the waterproof membrane sealing and laying device used in this invention includes:

[0009] The moving mechanism includes a vehicle body that moves along the edge sealing area. The top surface of the vehicle body is generally rectangular and a handrail is arranged on the rear side. The handrail is provided with grip bars at the top and bottom for easy holding.

[0010] A roll unwinding drum is arranged on the top surface of the vehicle body. A drive device is located at the input end of the roll unwinding drum and drives the roll unwinding drum to rotate. The waterproof membrane is wound on the roll unwinding drum and is released as the roll unwinding drum rotates.

[0011] The pressing and bonding part includes a horizontal connecting rod, a vertical support member and a pressing and rolling cylinder. The horizontal connecting rod is provided at the front end of the vehicle body. The vertical support members are a pair and are arranged vertically on the upper surface of the horizontal connecting rod with a gap between them. The pressing and rolling cylinder is rotatably arranged between the two vertical support members.

[0012] The tensioning section includes a flattening cylinder and tensioning rollers. The flattening cylinder is arranged between the unwinding cylinder and the pressing section. There are two tensioning rollers, which are respectively arranged on the upper and lower sides of the flattening cylinder and tension the waterproof membrane. The direction of the flattening cylinder is opposite to that of the unwinding cylinder.

[0013] An auxiliary compaction section includes at least one auxiliary compaction cylinder arranged parallel to the compaction cylinder below it.

[0014] A preheating section is located near the application area, with the heating surface of the preheating section facing the adhesive surface of the waterproof membrane.

[0015] There are two types of heating components: one is an inexpensive flame emitter, and the other is a more expensive but less polluting far-infrared heater. Specifically:

[0016] The heating element is a flame emitter, which is positioned in front of the waterproof membrane adhesive area, with the radiating end of the flame emitter facing the waterproof membrane adhesive area.

[0017] The heating element is a far-infrared heater, which is placed in front of the waterproof membrane adhesive area, with the radiating part of the far-infrared heater facing the waterproof membrane adhesive area.

[0018] in:

[0019] The aforementioned moving mechanism has two operating states. In the moving state, the lower surface of the vehicle body has a traditional wheel structure, making it easy to move. In the rolling state, the vehicle body is raised so that the rear part of the vehicle body is tilted to tilt the rolling cylinder forward and press it to bond the waterproof membrane.

[0020] The above-mentioned structure is designed as a laying device with dual modes of movement and laying. In the laying mode, the laying device can efficiently complete the sealing and laying of waterproof membrane by a single person in a short time, with fewer problems such as bubbles and wrinkles. In the moving mode, the laying device is easy to move. Since the unused waterproof membrane is placed on the laying device, it is convenient for workers to store, reducing the time spent on collecting materials. The operation is simple.

[0021] As a further optimization of the above solution, the vehicle body includes a single rear wheel and two parallel front wheels, with the front and rear wheels forming an inverted triangular structure. The diameter of the rear wheel is smaller than that of the front wheel. The inverted triangular tire structure and the small-diameter rear wheel make it easy for workers to lift the rear half of the vehicle body, and the entire vehicle body tilts backward, making it easy for workers to operate.

[0022] The method for sealing the edges of waterproof membrane includes the following steps:

[0023] a) Lift the vehicle body to lower the roller and bring it into contact with the edge sealing and paving area;

[0024] b) Unwind the roll to lay the waterproof membrane along the selected area of ​​the sealing area;

[0025] c) The preheating section and heating components heat the adhesive surface of the waterproof membrane;

[0026] d) The roller presses and rolls the waterproof membrane, moving the air bubbles formed under the membrane toward the side. The auxiliary roller then continuously presses the waterproof membrane to expel the moving air bubbles to the edge sealing area.

[0027] The above-mentioned installation method further improves the reliability and stability of the waterproof membrane edge sealing installation device.

[0028] The waterproof membrane sealing and laying device and method of the present invention have the following beneficial effects:

[0029] 1. The waterproof membrane sealing and laying device designed in this invention provides a laying device with dual modes: a moving state and a laying state. In the laying state, the device can efficiently complete the waterproof membrane sealing and laying work by a single person in a short time, with fewer air bubbles and wrinkles. In the moving state, the device is easy to move. Since the unused waterproof membrane is placed on the device, it is convenient for workers to store, reducing the time spent on collecting materials. The operation is simple and requires less skill from workers.

[0030] 2. The waterproof membrane edge sealing and laying method proposed in this invention further improves the reliability and stability of the waterproof membrane edge sealing and laying device.

[0031] 3. The waterproof membrane sealing and laying device designed in this invention is equipped with a tensioning part to adjust the tension of the waterproof membrane, making the laying of the waterproof membrane more stable, safe and reliable; it is also equipped with an auxiliary pressing part to continuously press the waterproof membrane to expel moving air bubbles to the sealing and laying area, thereby enhancing the sealing and laying effect.

[0032] 4. The waterproof membrane sealing and laying device designed in this invention has two heating structures: one is an inexpensive flame jet, which has a low cost; the other is a far-infrared heater, which has a high cost but less environmental pollution.

[0033] 5. The waterproof membrane sealing and laying device designed in this invention features an inverted triangular tire structure and a small-diameter rear wheel, which makes it easy for workers to lift the rear half of the vehicle and tilt the entire vehicle backward, making it easy for workers to operate.

[0042] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of the invention.

[0043] It should be noted that when an element is referred to as "set on" or "provided with" another element, it can be directly on the other element or there may be an intermediate element. When an element is referred to as "connected to" or "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. "Fixed connection" means fixed connection. There are many ways of fixed connection, which are not within the scope of protection of this document. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this document are only for illustrative purposes and do not represent the only implementation method.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in the specification herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] As per the instruction manual Figure 1-5 As shown, the first embodiment of the waterproof membrane edge sealing and laying device is as follows: The laying device is generally in the shape of a trolley, and specifically includes:

[0046] The moving mechanism 1 includes a vehicle body 11 that moves along the edge sealing area. The top surface of the vehicle body has a roughly rectangular structure, and a handrail is provided on the rear side. The handrail is provided with grip bars at the top and bottom for easy holding.

[0047] Specifically, in the moving state, the worker holds and pushes the moving mechanism 1 using the top handle; in the laying state, the worker holds and pushes the moving mechanism 1 using the bottom handle.

[0048] Unwinding drum 2 is arranged on the top surface of vehicle body 11. Driving device 21 is located at the input end of unwinding drum 2 and drives unwinding drum 2 to rotate. Waterproof membrane 3 is wound on unwinding drum 2 and released as unwinding drum 2 rotates.

[0049] Furthermore, the drive device 21 is a first electric motor, and the unwinding drum 2 is arranged on the output shaft of the first electric motor.

[0050] The pressing and bonding part 4 includes a horizontal connecting rod 41, vertical support members 42, and a pressing and rolling cylinder 43. The horizontal connecting rod 41 is provided at the front end of the vehicle body 11. The vertical support members 42 are a pair and are vertically arranged on the upper surface of the horizontal connecting rod 41 with a gap between them. The pressing and rolling cylinder 43 is rotatably arranged between the two vertical support members 42.

[0051] The aforementioned vehicle body 11 is raised so that the rear part of the vehicle body 11 is tilted so that the pressing cylinder 43 is tilted forward and lowered to press and adhere the waterproof membrane 3.

[0052] In summary, the waterproof membrane sealing and laying device designed in this invention provides a laying device with dual modes: a moving mode and a laying mode. In the laying mode, the device can efficiently complete the waterproof membrane sealing and laying work by a single person in a short time, with fewer air bubbles and wrinkles. In the moving mode, the device is easy to move, and since unused waterproof membrane is placed on the device, it is convenient for workers to store, reducing the time spent on collecting materials. The operation is simple and requires less skill from workers.

[0053] It should be noted that during the paving process, workers can push the moving mechanism 1 on both sides of the vehicle body 11. Of course, protective covers can also be added to the rear wheels 112. Alternatively, the rear wheels 112 can be designed as a detachable structure, and hooks for hanging the rear wheels 112 can be added to the side of the vehicle body.

[0054] As per the instruction manual Figure 1-5 As shown, the second embodiment of the waterproof membrane edge sealing and laying device is as follows: The laying device is generally in the shape of a trolley, and specifically includes:

[0055] The moving mechanism 1, the roll, and the pressing and bonding part 4 in the second embodiment are the same as those in the first embodiment, with further optimizations in that:

[0056] Tensioning section 5 includes a flattening cylinder 51 and a tensioning roller 52. The flattening cylinder 51 is arranged between the unwinding cylinder 2 and the pressing section 4. There are two tensioning rollers 52, which are respectively arranged on the upper and lower sides of the flattening cylinder 51 and tension the waterproof membrane 3.

[0057] Furthermore, the input end of the flattening cylinder 51 is located on the output shaft of the second motor, and the rotation direction of the flattening cylinder 51 is opposite to that of the unwinding cylinder 2, so as to flatten the unwound waterproof membrane 3.

[0058] The auxiliary pressing section 6 includes at least one auxiliary pressing cylinder 61 arranged parallel to the pressing cylinder 43 below. In this embodiment, the number of auxiliary pressing sections 6 is one.

[0059] The preheating section 7 is located near the laying area, and the heating surface of the preheating section 7 faces the adhesive surface of the waterproof membrane 3. Preferably, in this embodiment, the preheating section is a heating roller, and the roller surface of the heating roller is in contact with the adhesive surface of the waterproof membrane 3 to achieve preheating of the adhesive surface.

[0060] Furthermore, in this embodiment, to improve the adhesive bonding effect, a heating component 8 is also installed on the moving mechanism. Specifically, in this embodiment, the heating component 8 has two usage scenarios:

[0061] Heating component 8, which is a flame emitter 81, is placed in front of the adhesive part of the waterproof membrane 3, and the radiating end of the flame emitter 81 faces the adhesive part of the waterproof membrane 3. The advantage of the flame emitter 81 is its low cost.

[0062] Heating component 8, which is a far-infrared heater 82, is placed in front of the adhesive part of the waterproof membrane 3. The radiating part of the far-infrared heater 82 faces the adhesive part of the waterproof membrane. The advantage of the far-infrared heater 82 is that it has low environmental pollution.

[0063] As per the instruction manual Figure 1-5 As shown, the third embodiment improves upon the first embodiment. Specifically, this embodiment improves the wheel structure below the vehicle body 11 to better facilitate the switching between the moving state and the paving state. Specifically:

[0064] The vehicle body 11 includes a single rear wheel 111 and two parallel front wheels 112, with the front wheels 112 and the rear wheels 111 forming an inverted triangular structure. The diameter of the rear wheel 111 is smaller than the diameter of the front wheels 112.

[0065] The above-mentioned structural design features an inverted triangular tire structure and small-diameter rear wheels, which makes it easy for workers to lift the rear half of the vehicle and tilt the entire vehicle backward, making it easy for workers to operate.

[0066] like Figure 6 As shown, the method for sealing the edges of waterproof membrane includes the following steps:

[0067] a. Lifting the vehicle body 11 lowers the roller 43 to change the moving mechanism 1 from the moving state to the laying state, so that the roller 43 contacts the edge sealing laying area.

[0068] b. The first electric motor drives the unwinding drum 2 to rotate, so that the unwinding drum 2 unwinds the waterproof membrane 3 to be laid along the selected area of ​​the sealing and laying area.

[0069] c. The preheating section 7 and the heating component 8 heat the adhesive surface of the waterproof membrane 3.

[0070] The d-pressing cylinder 43 presses and rolls the waterproof membrane 3, and moves the air bubbles formed under the waterproof membrane 3 to the side. The rear auxiliary pressing cylinder 61 continuously presses the waterproof membrane 3 to expel the moving air bubbles to the edge sealing and laying area.

[0071] The above-mentioned installation method further improves the reliability and stability of the waterproof membrane edge sealing installation device.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
