Description

Technical Field

[0001] The invention relates to the technical field of overlapping waterproof coiled materials, in particular to an overlapping structure of waterproof coiled materials. Background Art

[0002] Waterproof membrane is a flexible building material mainly used in building walls, roofs, tunnels, roads, landfills, etc. It protects against external rainwater and groundwater seepage. It is the key to a leak-free connection between the project foundation and the building, and is also the first barrier to waterproofing the entire project. There are generally two ways to overlap waterproof membranes: manual overlapping and membrane overlapping machines.

[0003] However, currently when the waterproofing membrane overlaps the roof with a waterproofing membrane overlap machine, the membrane is generally rolled up on the pay-off roller, the waterproofing membrane is inserted into the bottom of the compacting mechanism through the guide roller, the heating mechanism heats the waterproofing membrane opposite to the ground, and as the machine moves, the heated waterproofing membrane contacts the ground, and the compacting mechanism rolls and reinforces the waterproofing membrane that is in contact with the ground; however, at the end of the waterproofing membrane, it is necessary to directly pass over the compacting rod to fix the end of the waterproofing membrane through the positioning component, and the waterproofing membrane pressed by the positioning component cannot be heated, and a secondary operation is required after the entire roll of waterproofing membrane is laid, which wastes time; in When the end of the waterproof membrane is embedded in the bottom of the compaction roller, it is compacted and pressed by the compaction roller. The starting end of the unheated waterproof membrane is not fixed. When laying, the dotted lines of the long sides of the two adjacent membranes need to be aligned.

The coverage area of ​​the broom is small, and it is easy to cause sand and gravel to be missed during cleaning. The overlap machine is not equipped with a dust suction component to clean the sand and gravel, which is easy to cause bulging of the membrane during overlap, and the insufficient fit affects waterproofing.

[0016] (1) In the waterproof roll material overlap structure described in the present invention, a reeling mechanism for placing the waterproof roll material is installed on the fixed plate. When laying the waterproof roll material on the roof, one end of the waterproof roll material is passed through two guide shafts and pulled out from the two guide shafts to the side of the pressure roller. The second electric push rod is retracted to ensure that the pressure roller does not contact the ground. At this time, the traction mechanism can be used to clamp and fix the end of the waterproof roll material on one side of the pressure roller, and the waterproof roll material is heated by the heating mechanism. The motor is started to pull the heated waterproof roll material through one side of the positioning shaft. In this way, the starting end of the waterproof roll material can also be heated, so that the starting point of the roll material can be bonded to the concrete without the need for secondary processing.

[0017] (2) The present invention discloses a waterproofing roll overlapping structure, in which a compacting mechanism and a positioning mechanism are provided on the retracting mechanism. When the traction mechanism pulls the heated waterproofing roll, the second electric push rod is in a retracted state. At this time, there is a large gap between the pressure roller and the concrete. At the same time, the pressure plate on the side of the slide does not conflict with the pressure frame, so the spring is in an open state. Then the pressure frame rises, and the positioning shaft also rises accordingly, leaving a large gap between the pressure roller and the concrete, which is convenient for the traction mechanism to clamp and pull the end of the heated roll to prevent burns. After the end of the heated roll is pulled to the bottom of the positioning shaft, the second electric push rod is extended to realize that the pressure roller and the positioning shaft press the roll at the same time, which is convenient for the starting point of the roll to correspond to the dotted line on the adjacent roll to reduce errors.

When the roll material is laid, the whole mechanism will move with the driven wheel as the head and the driving wheel as the tail. That is to say, the dust suction mechanism will first pass through the area to be laid, and the heating mechanism and the compacting mechanism will heat and compact the roll material. As the moving mechanism drives the moving suction head of the whole structure, the large particles of dust and sand and gravel on the surface of the concrete will be sucked into the inside of the vacuum cleaner to avoid bulging at the bonding point caused by the contact between the sand and gravel and the roll material, thereby increasing the adhesion between the concrete and the roll material. The collected sand and gravel fall between the partitions, and the steering wheel is turned to open the sealing plate. The collected sand and gravel are quickly discharged from the ash leakage port for easy cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

The cross-section of the pressure frame 503 is an inverted T-shaped structure, and the length of the pressure frame 503 is greater than the length between the two slide plates 402.

[0036] The coil is pulled toward the pressure roller 403. At this time, one surface of the coil is opposite to the nozzle 303. At this time, the clamp 606 can be clamped on the coil, and the control valve of the air pipe 302 is opened to realize the nozzle 303 to spray fire. The second electric push rod 401 is retracted to realize a larger gap between the pressure roller 403 and the positioning shaft 505 and the roof. The heated coil is passed over the bottom of the pressure roller 403 and the positioning shaft 505 by pulling the wire rope 605. The nozzles 303 arranged at equal distances improve the utilization rate of thermal energy, and no manual close work is required during the spraying of fire, which can avoid the construction workers being scalded by heat waves.

At this time, the second electric push rod 401 is started to realize the descent of the slide plate 402, and the pressure roller 403 Move in the direction of the coil, as the slide plate 402 descends, the pressure plate 504 is driven down, and the pressure plate 504 presses the pressure frame 503. At this time, the spring 506 contracts, so that the pressure roller 403 and the positioning shaft 505 can press the heated coil at the same time, and the positioning shaft 505 can press the end of the coil to position the end, which is beneficial to the alignment of the dotted lines on the long sides of the two adjacent coils to avoid crooked laying, and as the overall structure moves, the positioning shaft 505 can roll the end of the coil, and the positioning shaft 505 can also roll the coil rolled by the pressure roller 403 for the second time to increase the adhesion. The second electric push rod 401 contracts to realize the simultaneous rise of the positioning shaft 505 and the pressure roller 403, which is convenient for the wire rope 605 to pull the coil.

[0038] When laying waterproof membrane on the roof, the whole mechanism is moved to the roof, and the whole roll of membrane is placed between the two support seats 205. The two rotating blocks 209 can be held to rotate the two support seats 205. The two support seats 205 move back to back to facilitate the placement of the membrane. After determining the position, the support seats 205 are rotated in the opposite direction to achieve axial limitation of the membrane. At this time, the membrane can only rotate and will not fall, and the first electric push rod 202 can be started to control the lifting of the slider 204, so that the membrane is limited by the bottom roller 208 and will not loosen. As the number of membranes decreases, the slider 204 can be controlled to descend so that the membrane is always in conflict with the bottom roller 208, and the membrane is further passed between the two guide shafts 207.

[0039] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, the traction mechanism 6 includes a mounting plate 601, the sides of the two top frames 501 are fixedly connected with the mounting plate 601, the mounting plate 601 is rotatably connected with a rotating shaft 602, the rotating shaft 602 is fixedly connected with a winding disk 603, the two winding disks 603 are fixedly connected with steel wire ropes 605, and the ends of the two steel wire ropes 605 are fixedly connected with clips 606; the traction mechanism 6 also includes two guide wheels 604 and a motor 607, the mounting plate 601 is installed with a motor 607, the output end of the motor 607 is fixedly connected with the rotating shaft 602, and the opposite sides of the two top frames 501 are rotatably connected with the guide wheels 604 located at the bottom of the winding disk 603;

[0040] When the end of the coil is pulled to the left side of the pressure roller 403, the end of the coil is clamped by the clamp 606. After the nozzle 303 heats the end of the coil, the motor 607 is started to realize the rotating shaft 602 to drive the winding disk 603 to rotate, so that the wire rope 605 is wound up, and as the wire rope 605 is wound up, the clamp 606 will pass through the pressure roller 403 and the bottom of the positioning shaft 505 to realize the traction of the heated coil. No manual traction is required to avoid burns. When the end of the coil corresponds to the bottom of the positioning shaft 505, the traction is stopped and the second electric push rod 401 is controlled to extend to realize the lowering of the positioning shaft 505 and the pressure roller 403 to press the coil, and the clamp 606 is released. The end of the coil can be heated from the beginning, and the end of the coil can be positioned, pressed and heated by the positioning shaft 505 without secondary processing.

[0041] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 8 , Fig. 9 and Fig.10As shown, the mobile mechanism 7 includes a bottom plate 701, the bottom of the fixed plate 1 is fixedly connected to the bottom plate 701, two driven wheels 702 are installed on the bottom plate 701, two driving wheels 705 are installed on the bottom plate 701, a controller 703 is installed on the fixed plate 1, a handle 704 is installed on the controller 703, and the air pipe 302 is installed on the bottom plate 701; the dust collection mechanism 8 includes a dust collector 801, a dust collector 801 is installed on the bottom plate 701, a suction head 807 is provided on the dust collector 801, and the dust collector 801 is provided with a suction head 807. One end of the head 807 is installed at the bottom of the bottom plate 701. The interior of the vacuum cleaner 801 is fixedly connected with a plurality of partitions 803 in an annular array. The bottom annular array of the vacuum cleaner 801 is provided with a plurality of ash leakage ports 804. The ash leakage ports 804 are connected with the cavity between two adjacent partitions 803. A rotating seat 805 is rotatably connected at the bottom center of the vacuum cleaner 801. The side of the rotating seat 805 is fixed with a plurality of sealing plates 806 located at the bottom of the ash leakage ports 804 in a circumferential array. A steering plate 802 is installed on the side of the rotating seat 805.

[0042] When laying the waterproof membrane, the driving wheel 705 can be rotated by remote control in coordination with the controller 703, and after the driving wheel 705 rotates, the overall structure can be moved toward the driven wheel 702. As the membrane is continuously heated and rolled on the roof to complete continuous overlap, the vacuum cleaner 801 can be started when the overall structure moves to enable the suction head 807 to clean the roof that is about to be laid, so as to avoid bulging caused by contact between sand and gravel and the membrane, which affects the adhesion of the membrane and causes water leakage. The sucked sand and gravel enter the interior of the vacuum cleaner 801 and fall between two adjacent partitions 803. After the construction is completed, the steering wheel 802 can be rotated to realize the rotation of the rotating seat 805, and the sealing plate 806 is staggered with the ash leakage port 804, and the sand and gravel located between the adjacent partitions 803 fall from the ash leakage port 804, thereby starting to clean the sand and gravel.

[0043] When the present invention is used, first, when laying the waterproofing coiled material on the roof, the whole mechanism is moved to the roof, and the whole roll of the coiled material is placed between the two support seats 205. The two rotating blocks 209 can be held to rotate the two support seats 205. The two support seats 205 move back to back to facilitate the placement of the coiled material. After the position is determined, the support seats 205 are rotated in the opposite direction to achieve axial limitation of the coiled material. At this time, the coiled material can only rotate and will not fall, and the first electric push rod 202 can be started to control the lifting of the slider 204, so that the coiled material is limited by the bottom roller 208 The coil will not loosen. As the coil becomes less, the slider 204 can be controlled to descend so that the coil is always in conflict with the bottom roller 208. The coil is further passed between the two guide shafts 207, and the coil is pulled in the direction of the pressure roller 403. At this time, one surface of the coil is opposite to the nozzle 303. At this time, the clamp 606 can be clamped on the coil, and the control valve of the air pipe 302 is opened to realize the nozzle 303 spraying fire. The second electric push rod 401 is contracted to realize a larger gap between the pressure roller 403 and the positioning shaft 505 and the roof. The heated coil is realized by pulling the wire rope 605. The nozzles 303 are arranged equidistantly over the pressure roller 403 and the bottom of the positioning shaft 505, and the utilization rate of heat energy is improved. There is no need for manual close work during the flame spraying, which can avoid the construction workers being scalded by the heat wave. The heated end of the coil is stopped at the bottom of the positioning shaft 505. At this time, the second electric push rod 401 is started to realize the descending of the slide plate 402, and the pressure roller 403 moves toward the coil. As the slide plate 402 descends, the pressing plate 504 is driven to descend, and the pressing plate 504 presses the pressing frame 503. At this time, the spring 506 contracts, and the pressure roller 40 3 and the positioning shaft 505 press the heated coil at the same time, and the positioning shaft 505 can press the end of the coil to realize the positioning of the end, which is conducive to the alignment of the dotted lines on the long sides of the two adjacent coils to avoid skewing, and with the movement of the overall structure, the positioning shaft 505 can roll the end of the coil, and the positioning shaft 505 can also roll the coil rolled by the pressure roller 403 for the second time to increase the adhesion. The second electric push rod 401 contracts to realize the simultaneous rise of the positioning shaft 505 and the pressure roller 403, which is convenient for the steel wire rope 605 to pull the coil;

[0044] Then, when the end of the coil is pulled to the left side of the pressure roller 403, the end of the coil is clamped by the clamp 606. After the nozzle 303 heats the end of the coil, the motor 607 is started to realize that the rotating shaft 602 drives the winding disk 603 to rotate, so that the wire rope 605 is wound up, and as the wire rope 605 is wound up, the clamp 606 will pass through the bottom of the pressure roller 403 and the positioning shaft 505 to realize the traction of the heated coil, without manual traction to avoid burns. When the end of the coil corresponds to the bottom of the positioning shaft 505, the traction is stopped and the second electric push rod 401 is controlled to extend to realize the lowering of the positioning shaft 505 and the pressure roller 403 to press the coil, and the clamp 606 is released, so that the end of the coil can be heated from the beginning, and the end of the coil can be positioned, pressed and heated by the positioning shaft 505 without secondary processing.

[0045] Finally, when laying the waterproof membrane, the driving wheel 705 can be rotated by remote control in coordination with the controller 703, and after the driving wheel 705 rotates, the overall structure can be moved toward the driven wheel 702. As the membrane is continuously heated and rolled on the roof to complete continuous overlap, the vacuum cleaner 801 can be started when the overall structure moves to realize the suction head 807 to clean the roof that is about to be laid, so as to avoid bulging caused by contact between sand and gravel and the membrane, which affects the adhesion of the membrane and causes water leakage. The sucked sand and gravel enter the interior of the vacuum cleaner 801 and fall between two adjacent partitions 803. After the construction is completed, the steering wheel 802 can be rotated to realize the rotation of the rotating seat 805, and the sealing plate 806 is staggered with the ash leakage port 804, and the sand and gravel located between the adjacent partitions 803 fall from the ash leakage port 804, so as to realize the beginning of cleaning of the sand and gravel; the overlap width of the membrane should meet the design requirements and generally should not be less than 100mm; the overlap width of the long side should be ≥80mm; the overlap width of the short side should be ≥100mm.
