Description

Technical Field

[0001] This invention relates to a waterproof membrane construction technology, specifically a waterproof membrane edge finishing device and construction method. Background Technology

[0002] To prevent water leakage from the top floor or basement floor of a building due to rain or snow, the building foundation and roof need to be waterproofed. This is usually done by laying waterproof membrane.

[0003] Currently, the laying and sealing of waterproof membrane rolls are all done manually. There are two common sealing methods. The first method is that one operator holds a spray gun to heat the hot melt adhesive on the bottom layer of the membrane roll, while another operator uses a heated metal trowel to press and seal the joint. The second method is that the operator directly uses an existing round-headed blowtorch to heat the membrane roll first and then press it firmly.

[0004] Existing construction methods have the following disadvantages:

[0005] 1. During the construction process, two construction workers need to bend over or squat down to operate, which consumes a lot of labor and results in low work efficiency.

[0006] 2. The construction area is limited, and the gas cylinders need to be moved frequently. Moving the gas cylinders can easily tear the membrane and affect the waterproofing effect.

[0007] 3. Improper edge sealing construction can lead to quality defects such as bubbling and curling at the overlap joints, which can easily cause cracking and leakage during use. Repairing leaks in the roll material is very difficult. Summary of the Invention

[0008] The purpose of this invention is to provide a waterproof membrane edge-sealing device and construction method to solve the problems of low efficiency, easy damage to the membrane, and poor sealing effect of existing waterproof membrane construction methods.

[0009] The present invention is implemented as follows: a waterproof membrane edge-gathering device includes a frame body, a guide wheel provided at the front of the frame body, a roller provided at the rear of the frame body, a mounting bracket for mounting a gas cylinder provided at the upper part of the frame body, a handrail for driving and controlling the movement of the frame body provided at the rear of the frame body, a flame nozzle provided at the lower part of the frame body, a gas guide pipe for connecting to the gas cylinder connected to the flame nozzle, a lifting rod for lifting the membrane overlap seam provided at the lower part of the frame body, and a cantilever linkage device for controlling the lifting rod to move up and down and extend and retract left and right on one side of the frame body.

[0010] The telescopic linkage device includes a rotating rod that can rotate freely and is mounted on the frame. An L-shaped lifting rod is threaded to the lower end of the rotating rod. A guide is provided on the frame to guide the lifting rod to move up and down. A lifting rod is inserted into the end of the horizontal section of the lifting rod. A rope is connected to the inner end of the lifting rod. The rope passes through the interior of the lifting rod and is connected to the rotating rod. A spring is provided in the horizontal section of the lifting rod. One end of the spring is fixed, and the other end contacts the lifting rod.

[0011] A top plate is provided at the top of the rotating rod, and a bearing is provided at the center of the top plate. The upper end of the rope is connected to the inner ring of the bearing, and a rotating handle is provided on the top plate.

[0012] The guide component is a guide plate with a vertical guide hole, through which the horizontal section of the lifting rod passes.

[0013] An observation hole is provided on the vehicle frame, and the observation hole is located above the lifting rod and the flame nozzle.

[0014] An elastic scraper is provided next to the grinding wheel, and the elastic scraper is in contact with the surface of the grinding wheel.

[0015] A positioning mark is provided on the vehicle frame, and the positioning mark is located on the central axis of the vehicle frame.

[0016] Two baffles are provided at the bottom of the vehicle frame, one at the front and one at the rear, respectively, on the front and rear sides of the flame nozzle.

[0017] The present invention also discloses a method for edge finishing of waterproof membrane, including the following steps.

[0018] a. Prepare the waterproof membrane edge-sealing device as described above, install the gas cylinder on the mounting frame and connect the gas pipe to the gas outlet of the gas cylinder, move the waterproof membrane edge-sealing device to the membrane overlap seam, and make the roller press directly above the membrane overlap seam.

[0019] b. Control the lifting rod to move down to the bottom through the extension linkage device, and at the same time retract the lifting rod to the outer edge of the roll overlap seam.

[0020] c. Manually lift the roll material overlap seam, and control the lifting rod to gradually extend and insert it under the roll material through the lifting telescopic linkage device. At the same time, the lifting rod moves upward to lift the edge of the roll material to a suitable height.

[0021] d. Open the gas cylinder valve and ignite it, adjusting the flame size.

[0022] e. Push the waterproof membrane edge sealing device along the membrane overlap seam, and use the roller to press the membrane overlap seam to seal the heated and softened membrane edge.

[0023] f. Before starting construction, conduct a test section to check the quality of the membrane sealing, determine parameters such as flame size and walking speed, and check the sealing condition of the membrane edges. If it passes the test, continue construction along the membrane overlap joint.

[0024] In step b, the rotating rod is rotated to move the lifting rod downward while it retracts; in step c, the rotating rod is rotated in the opposite direction to extend the lifting rod while it moves upward.

[0025] This invention first discloses a waterproof membrane edge sealing device. This device requires only one operator to push and perform edge sealing work on waterproof membranes, greatly saving manpower and improving construction efficiency. The device mounts a gas cylinder on a vehicle frame. On one hand, the gas cylinder moves directly with the vehicle frame, eliminating the need to move the cylinder every certain distance during construction, thus avoiding damage to the membrane from repeated cylinder movements. Furthermore, the pressure from the gas cylinder on the membrane is distributed through rollers and guide wheels, preventing excessive pressure from damaging the membrane. On the other hand, the device utilizes the weight of the gas cylinder to apply pressure to the heated membrane overlap seam via the rollers, thereby compacting and sealing the overlap seam and ensuring the quality of the edge sealing.

[0026] Meanwhile, the device can realize the linkage action of inserting the lifting rod under the roll material and lifting the roll material at the same time, which is easy to operate. During operation, the height of the roll material can be adjusted at any time so that the flame can effectively heat the roll material, thereby ensuring the sealing effect of the roll material.

[0027] The waterproof membrane edge-sealing construction method of the present invention utilizes the above-mentioned waterproof membrane edge-sealing device. The construction method is simple to operate and only requires one operator. After adjusting the device, it can be moved along the membrane overlap seam. The construction speed is fast, the effect is good, and the construction period and cost are saved. Attached Figure Description

[0037] like Figure 1 , Figure 2 as well as Figure 3 As shown, the waterproof roll edge finishing device of the present invention includes a frame body 1, which is a plate-shaped structure. A guide wheel 4 is installed at the front of the lower surface of the frame body 1, and a roller 5 is installed at the rear of the lower surface of the frame body 1. The frame body 1 is supported by the roller 5 and the guide wheel 4.

[0038] A mounting bracket 2 is installed on the rear of the upper surface of the vehicle frame 1. The mounting bracket 2 is used to place and fix the gas cylinder 3. A handrail 10 is installed on the rear of the vehicle frame 1. The operator can drive the entire device to move and control the direction of the device by using the handrail 10.

[0039] A flame nozzle 6 is installed below the frame body 1, and an air guide pipe 9 is connected to the flame nozzle 6. The air guide pipe 9 is also connected to the air cylinder 3. A lifting rod 8 is installed below the frame body 1, and a lifting telescopic linkage device 7 is installed on one side of the frame body 1 to control the up-and-down movement and left-and-right extension of the lifting rod 8. The edge of the waterproof membrane is lifted by the lifting rod 8. The flame nozzle 6 is located behind the lifting rod 8. After the lifting rod 8 lifts the edge of the waterproof membrane, the flame nozzle 6 sprays flames downwards onto the lifted waterproof membrane to heat and soften it.

[0040] Among them, the guide wheel 4 is a swivel wheel, which enables the frame 1 to move and turn. The guide wheel 4 has a large diameter, which makes the entire frame 1 tilted, and the center of gravity of the entire device shifts backward, thus applying most of the weight of the entire device to the roller 5.

[0041] like Figure 5 , Figure 6 , Figure 7 as well as Figure 8 As shown, the telescopic linkage device 7 includes a rotating rod 7-1 mounted on the frame body 1. The rotating rod 7-1 is mounted on one side of the frame body 1 via a first bearing 7-6, and can rotate freely within the first bearing 7-6. An L-shaped lifting rod 7-2 is threadedly connected to the lower end of the rotating rod 7-1. A guide is provided on the frame body 1 to guide the lifting rod 7-2 to move up and down. A lifting rod 8 is inserted into the end of the horizontal section of the lifting rod 7-2. When the rotating rod 7-1 rotates, it drives the lifting rod 7-2 to move up and down, thereby realizing the up and down movement of the lifting rod 8.

[0042] Meanwhile, a rope 7-4 is connected to the inner end of the lifting rod 8. The rope 7-4 passes through the interior of the lifting rod 7-2 and connects to the interior of the rotating rod 7-1. A spring 7-5 is installed in the horizontal section of the lifting rod 7-2. One end of the spring 7-5 is fixed, and the other end is in contact with the lifting rod 8. In the initial state, the rope 7-4 is just taut, and the spring 7-5 is just under force. At this time, the lifting rod 7-2 is at its uppermost position. When the lifting rod 7-2 moves downward, the relative position of the lifting rod 7-2 and the rotating rod 7-1 changes, the rope 7-4 becomes taut, pulling the lifting rod 8 to retract into the lifting rod 7-2. At the same time, the spring 7-5 is compressed until the lifting rod 8 moves to the lowest position, at which point the extension length of the lifting rod 8 is the shortest. When the lifting rod 7-2 moves upward, the force on the rope 7-4 gradually decreases, and the compressed spring 7-5 is gradually released. The spring 7-5 pushes the lifting rod 8 to extend outward, and when the lifting rod 7-2 moves to the highest position, the extension length of the lifting rod 8 is the longest.

[0043] The rotating rod 7-1 and the lifting rod 7-2 are linked by a sleeve with internal threads. The lower end of the sleeve is fixedly connected to the upper end of the L-shaped lifting rod 7-2, and the upper end of the sleeve is threadedly connected to the external thread at the lower end of the rotating rod 7-1. When the rotating rod 7-1 rotates around its own axis, the lifting rod 7-2 will not rotate due to the constraint of the guide, so the lifting rod 7-2 moves up and down driven by the thread. As the lifting rod 7-2 moves downward, the rope 7-4 pulls the lifting rod 8 to retract; as the lifting rod 7-2 moves upward, the rope 7-4 relaxes, and the spring pushes the lifting rod 8 to extend.

[0044] A top plate is installed at the top of the rotating rod 7-1, and a second bearing 7-7 is installed at the center of the top plate. The upper end of the rope 7-4 is connected to the inner ring of the second bearing 7-7. A rotating handle 7-3 is also provided on the top plate. The rotating rod 7-1 is driven to rotate by rotating the handle 7-3. When the rotating rod 7-1 rotates, the inner ring of the bearing can rotate relative to the outer ring, thereby preventing the rope 7-4 from twisting and affecting normal operation.

[0045] A corner pulley 7-8 is installed on the inner wall at the corner of the lifting rod 7-2. The rope 7-4 is attached to the corner pulley 7-8, so that the rope 7-4 can pass smoothly through the corner of the lifting rod 7-2.

[0046] Among them, the guide component is a guide plate 7-9, which is vertically fixed to one side of the frame body 1. A vertical guide hole 7-10 is opened on the guide plate 7-9. The horizontal section of the lifting rod 7-2 passes through the guide hole 7-10, and the lifting rod 7-2 can only move up and down along the guide hole 7-10.

[0047] An observation hole 16 is provided on the frame body 1. The observation hole 16 is located above the lifting rod 8 and the flame nozzle 6. The working status of the lifting rod 8 can be clearly seen through the observation hole 16, which is convenient for controlling it. At the same time, the working status of the flame nozzle 6 can be observed, which is convenient for adjusting the flame size. An isolation net is installed on the observation hole 16 to prevent debris from entering the working area through the observation hole 16 and to protect the operator.

[0048] An elastic scraper 13 is installed next to the roller 5. The elastic scraper 13 is in contact with the surface of the roller 5 and is located behind the roller 5. The elastic scraper 13 can scrape off the debris adhering to the roller 5 to ensure the flatness of the roller 5 surface, thereby ensuring the rolling quality of the roller 5.

[0049] Specifically, the elastic scraper 13 is mounted on the frame 1 via an elastic hinge, and the lower side of the elastic scraper 13 is kept in close contact with the surface of the roller 5 via the elastic hinge.

[0050] Two baffles 14 are provided at the bottom of the frame body 1. The two baffles 14 are located on the front and rear sides of the flame nozzle 6, respectively, and the front and rear components are protected by the baffles 14.

[0051] Meanwhile, a fireproof and heat-insulating layer 15 is installed on the lower surface of the vehicle frame 1 and the front side of the mounting bracket 2. The fireproof and heat-insulating layer 15 protects the gas cylinder 3 and prevents the gas cylinder 3 from being dangerous at high temperatures.

[0052] The gas outlet of the gas cylinder 3 is connected to the switch 11 and regulating valve 12 on the handrail 10 through the gas guide pipe 9, and then to the flame nozzle 6. The operator can control the switch 11 and flow rate of the combustible gas while controlling and driving the entire device through the handrail 10, thereby controlling the flame size.

[0053] The nozzle 6 has a flat nozzle structure, which can spray a flat flame to heat the lower hot melt layer and base layer of the roll material.

[0054] In addition, a positioning mark 17 is provided on the frame body 1. The positioning mark 17 is located on the central axis of the frame body 1. When in use, the positioning mark 17 is aligned with the center line of the area between the edges of the two waterproof membranes at the joint. Since the roller 5 has a certain length, the roller 5 can completely roll the waterproof membrane overlap joint at this time.

[0055] The waterproof membrane edge sealing device of the present invention can be pushed by only one operator, thereby performing edge sealing construction of waterproof membrane, which greatly saves manpower and improves construction efficiency.

[0056] The waterproof membrane edge-sealing device of the present invention mounts the gas cylinder 3 on the vehicle frame 1. On the one hand, it allows the gas cylinder 3 to move directly with the vehicle frame 1, eliminating the need to move the gas cylinder 3 every certain distance during construction, thus preventing scratches on the waterproof membrane when moving the gas cylinder 3. Furthermore, the pressure exerted by the gas cylinder 3 on the membrane is dispersed by the roller 5 and guide wheel 4, preventing excessive pressure from damaging the membrane. On the other hand, when sealing the edges of the membrane, a certain pressure is required to ensure a tight fit. The waterproof membrane edge-sealing device of the present invention utilizes the weight of the gas cylinder 3. The entire device, plus the weight of the gas cylinder 3, is applied to the heated edge of the membrane via the roller 5. The applied pressure compacts and seals the membrane overlap, thereby ensuring the quality of the edge sealing.

[0057] This method solves the problem of moving gas cylinder 3, while also utilizing the weight of gas cylinder 3 to ensure the tightness of the sealing, achieving two goals at once and eliminating gas cylinder 3 from being a burden during the sealing process of waterproof membrane.

[0058] The waterproof membrane sealing device of the present invention can realize the linkage action of inserting the lifting rod 8 under the membrane and lifting the membrane at the same time, which is convenient to operate. Moreover, the height of the membrane being lifted can be adjusted at any time during operation so that the flame can effectively heat the membrane, thereby ensuring the sealing effect of the membrane.

[0059] The waterproof membrane edge finishing construction method of the present invention includes the following steps.

[0060] a. Prepare the waterproof membrane edge-gathering device as described above, install the gas cylinder 3 on the mounting frame 2 and connect the gas pipe 9 to the gas outlet of the gas cylinder 3, move the waterproof membrane edge-gathering device to the membrane overlap seam, and make the roller 5 press directly above the membrane overlap seam.

[0061] b. The lifting rod 8 is controlled to move down to the bottom by the extension linkage device 7, and at the same time the lifting rod 8 retracts to the outer edge of the roll material overlap seam.

[0062] c. Manually lift the roll material overlap seam, and control the lifting rod 8 to gradually extend and insert it under the roll material through the lifting telescopic linkage device 7. At the same time, the lifting rod 8 moves upward to lift the edge of the roll material to a suitable height.

[0063] d. Open valve 3 of gas cylinder and ignite it, adjusting the flame size.

[0064] e. Push the waterproof membrane edge sealing device along the membrane overlap seam, and use the roller 5 to roll the membrane overlap seam to seal the heated and softened membrane edge.

[0065] f. Before starting construction, a test section should be constructed to check the quality of the membrane sealing, determine parameters such as flame size and walking speed, and check the sealing condition of the membrane edges. If it passes the test, continue construction along the membrane overlap joint.

[0066] When adjusting the position of the device, it can be determined by the positioning mark 17 on the frame body 1, so that the positioning mark 17 is aligned with the center line of the waterproof membrane overlap, and the positioning mark 17 is kept in the corresponding position relationship with the center line of the overlap when moving, so as to ensure the position of the roller 5.

[0067] The movement of the lifting rod 8 is achieved by rotating the handle 7-3. Rotating the handle 7-3 drives the rotating rod 7-1 to rotate, causing the lifting rod 8 to move downward and retract simultaneously, so as to send the lifting rod 8 under the roll material. Then, rotating the rotating rod 7-1 in the opposite direction causes the lifting rod 8 to extend and move upward, inserting the lifting rod 8 under the roll material and lifting it up. The entire operation process is achieved by the operator through the rotating handle 7-3 on the top of the frame body 1, which is convenient to operate and reduces the workload of the operator.

[0068] During the installation of waterproof membrane, if it is necessary to adjust the height of the membrane, it can be quickly and easily adjusted by simply rotating the handle 7-3.

[0069] The waterproof membrane edge-terminating construction method of the present invention utilizes the above-mentioned waterproof membrane edge-terminating device. The construction method is simple to operate and only requires one operator. After adjusting the device, it can be moved along the edge of the membrane. The construction speed is fast, the effect is good, and the construction period and cost are saved.
