Description

Technical Field

[0001] The utility model belongs to the technical field of building waterproof construction, and specifically relates to a waterproof coiled material paving device. Background Art

[0002] The laying of waterproofing membrane is a key task in waterproofing engineering, and the quality of the laying of membrane directly affects the waterproof function of the building. There are two ways to lay waterproofing membrane: hot application and cold application. Hot application is to heat the waterproofing membrane before laying it, and cold application is to lay the waterproofing membrane with glue. Before laying the waterproofing membrane, the surface of the laying base should be cleaned to prevent the dust on the surface of the laying base from affecting the bonding of the waterproofing membrane and the laying base. The pasting of traditional waterproofing membranes requires at least two people to cooperate with each other, one to heat the membrane or apply glue, and the other to stretch and flatten the membrane before laying it. After the waterproofing membrane is bonded to the laying base, it is necessary to roll the waterproofing membrane to drive away the bubbles between it and the surface of the laying base. The labor intensity is high, manpower is wasted, and the construction progress is slow.

[0003] The Chinese patent with publication number CN212613440U records a waterproofing membrane laying device, which includes a frame and wheels. The frame is provided with a rotating roller for installing and unfolding the waterproofing membrane. The lower part of the frame is also provided with a blowtorch and a roller pressing device. The blowtorch is used to heat the membrane to make it sticky, and the roller pressing device is used to compact the laid membrane onto the surface of the construction base. Although this device can reduce the workload of the staff and improve work efficiency, it does not have a flattening mechanism for stretching and flattening the membrane. If the waterproofing membrane is not flattened and is bonded to the ground, wrinkles will occur, affecting the quality of the waterproofing construction, and even causing rework, which is time-consuming and labor-intensive. On-site construction often involves the laying of waterproofing membranes of various specifications. The widths of waterproofing membranes of different specifications are different. When the device is used to lay waterproofing membranes, the device cannot fix waterproofing membranes with smaller widths, which can easily cause the membranes to shift during the laying process.

DETAILED DESCRIPTION

[0029] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0030] As attached Figure 1-4 As shown, a waterproof coiled material laying device comprises a frame 1, on which casters 11, columns 21 and flattening rollers 3 are provided; two columns 21 are provided, between the two columns 21 is provided a detachable cross bar 22 arranged along the axial direction of the rotating shaft of the casters 11, and the cross bar 22 is provided with an axial limit mechanism for the coiled material; the flattening roller 3 is arranged parallel to the cross bar 22 and can rotate around its own axis; the frame 1 is also provided with a translation mechanism 4, on which a lifting mechanism 5 is connected, and the flattening roller 3 is connected to the lifting mechanism 5; the translation mechanism 4 can drive the lifting mechanism 5 to reciprocate linearly in a horizontal direction perpendicular to the axial direction of the cross bar 22, and the lifting mechanism 5 can drive the flattening roller 3 to move up and down.

[0031] Before using the utility model, the waterproof coiled material 9 needs to be installed on the cross bar 22 in advance, and the waterproof coiled material 9 is located between the two columns 21, and the coiled material axial limit mechanism limits the waterproof coiled material 9 in the axial direction of the cross bar 22. During the coiled material paving construction, the paving end of the waterproof coiled material 9 is bonded to the ground below the frame 1, the end of the waterproof coiled material located on the cross bar 22 is the rotating end, and the flattening section is between the paving end and the rotating end of the waterproof coiled material 9, and the flattening roller 3 is located on the upper surface of the flattening section of the waterproof coiled material 9. When laying the iron waterproofing coiled material 9, the translation mechanism 4 drives the lifting mechanism 5 and the flattening roller 3 to be located at the horizontal limit position away from the rotating end of the waterproofing coiled material 9, and the lifting mechanism 5 drives the flattening roller 3 to move downward to press the laying end of the waterproofing coiled material 9 on the surface of the construction base, and the pushing device continues to move forward, and the rotating end of the waterproofing coiled material 9 continues to rotate and unfold, and the translation mechanism 4 drives the lifting mechanism 5 and the flattening roller 3 on the lifting mechanism 5 to reciprocate horizontally, thereby flattening the flattened section of the waterproofing coiled material 9 and laying it flatly on the surface of the construction base. The flattening roller 3 can abut against the upper surface of the waterproofing coiled material 9 that has been laid and reciprocate horizontally to eliminate bubbles between the waterproofing coiled material 9 that has been laid and the construction base, so that the waterproofing coiled material 9 is flatly attached to the construction base, improving the laying quality of the coiled material and reducing the labor intensity of the operators. The distance of the flattening roller 3 relative to the surface of the construction base is adjustable, so that the device is suitable for laying waterproofing coiled materials 9 of different thicknesses. The utility model improves the laying flatness of the waterproof coiled material 9 by arranging a flattening roller 3 which is height-adjustable and can reciprocate horizontally, so that the waterproof coiled material 9 is closely laid on the surface of the construction base plate, thereby improving the laying quality of the waterproof coiled material.

[0032] The frame 1 is used to install and integrate other components to form an integral device. There should be at least 3 casters 11. In order to ensure the smooth operation of the device, generally, at least 4 casters 11 are provided, and at least 4 casters 11 are evenly distributed at the bottom of the frame 1. The frame 1 should also be provided with a push handle 11 so that the operator can push the device to move. The crossbar 22 is used to install the waterproof roll 9, and the column 21 is used to install and support the crossbar 22 to avoid interference between the waterproof roll 9 on the crossbar 22 and the frame 1, and to ensure that the waterproof roll 9 sleeved on the crossbar 22 can rotate around its axis and unfold. The installed crossbar 22 can be rotatably connected to the column 21, or it can be fixedly connected to the column 21 by overlapping, bolting, etc. The cross-sectional outer contour of the crossbar 22 can be any structure, such as a rectangular structure, a circular structure, or a regular hexagonal structure. Preferably, the cross-sectional outer contour of the crossbar 22 is a circular structure to reduce the friction of the crossbar 22 on the inner wall of the waterproof roll 9 and ensure that the waterproof roll 9 can rotate smoothly.

[0033] The coil axial limiting mechanism is used to limit the axial limit of the waterproof coil 9 on the cross bar 22 to avoid axial deviation of the waterproof coil 9 during laying, which causes the waterproof coil 9 laid on the construction base to deviate greatly and affect the waterproof effect. The coil axial limiting mechanism can be connected to the frame 1, the cross bar 22 or the column 21. The coil axial limiting mechanism can be two limiting members arranged at intervals along the axial direction of the cross bar 22. The two limiting members can be the same or different. The limiting members can be structures such as blocks, baffles, bolts or pins. The position of the limiting member in the axial direction of the cross bar 22 can be fixed or adjustable. Preferably, the coil axial limiting mechanism includes two first sliding sleeves 23 sleeved on the cross bar 22, and the two first sliding sleeves 23 are arranged opposite to each other and at intervals in the axial direction of the cross bar 22; and also includes a telescopic push rod 24 that can be telescopic along the axial direction of the cross bar 22, the fixed end of the telescopic push rod 24 is connected to the column 21, and the telescopic end of the telescopic push rod 24 is connected to the first sliding sleeve 23. The telescopic push rod 24 drives the first sliding sleeve 23 to extend and retract synchronously, thereby adjusting the relative positions of the two first sliding sleeves 23 on the cross bar 22, so that the device is suitable for laying waterproof rolls 9 of different widths. The axial distance between the two first sliding sleeves 23 on the cross bar 22 should be greater than the length of the waterproof roll 9, so as to avoid the first sliding sleeve 23 pressing against the end face of the waterproof roll 9, which makes the waterproof roll 9 unable to rotate and unfold. However, the distance between the first sliding sleeve 23 and the end face of the waterproof roll 9 should not be too large, so as to avoid the rotation end of the waterproof roll 9 displacing along its axial direction, causing the laying end of the waterproof roll 9 to deviate during laying, and even causing two adjacent waterproof rolls 9 laid on the construction base to not overlap, which ultimately leads to water seepage in the building after construction is completed, affecting its use and requiring rework. Preferably, the distance between the first sliding sleeve 23 and the end face of the waterproof roll 9 is 2 cm, which ensures that the laying error of the waterproof roll 9 is within the allowable range and improves the laying quality of the waterproof roll.

[0034] The translation mechanism 4 can be an automatic push rod or a horizontal transmission structure driven by a motor. The lifting mechanism 5 can be a lifting push rod or a lifting transmission structure driven by a motor. Although the automatic push rod has a simple structure, most of them are pneumatic push rods or hydraulic drag rods, and it is difficult to provide hydraulic pipelines or air sources at the construction site. Preferably, the translation mechanism 4 includes a horizontal transmission mechanism 41 and a first horizontal guide rail 42, and the length direction of the first horizontal guide rail 42 is perpendicular to the axis of the cross bar 22; the lifting mechanism 5 includes a connecting frame 51 connected to the horizontal transmission mechanism 41 for horizontal transmission, and the connecting frame 51 is slidably connected to the first horizontal guide rail 42; the connecting frame 51 is provided with a lifting transmission mechanism 52 and a lifting guide rail 53, the flattening roller 3 is slidably connected to the lifting guide rail 53, and the flattening roller 3 is connected to the lifting transmission mechanism 52 for lifting transmission. When the coil is laid, the horizontal transmission mechanism 4 drives the connecting frame 51 to move linearly along the length direction of the first horizontal guide rail 42 on the frame 1, and the connecting frame 51 drives the lifting transmission structure 52, the lifting guide rail 53 and the flattening roller 3 to move horizontally synchronously, and the lifting mechanism 52 drives the flattening roller 3 to move up and down along the lifting guide rail 53 on the connecting frame 51, that is, the flattening roller 3 can simultaneously complete translation movement, lifting movement and rotation around its own axis. In order to ensure the stability of the lifting movement of the flattening roller 3, preferably, the lifting mechanism 5 includes two sets of the lifting transmission mechanisms.

[0035] The horizontal transmission mechanism 41 and the lifting transmission structure 52 can both adopt any one of a screw transmission structure, a chain transmission structure, a synchronous belt transmission structure or a gear rack transmission structure. Specifically, the first horizontal guide rail 42 is a horizontal guide groove installed on the frame 1, and the horizontal transmission mechanism 41 is a horizontal screw pair installed in the horizontal guide groove; the lifting guide rail 53 is a lifting guide groove located on the connecting frame 51, and the lifting transmission mechanism 52 is a lifting screw pair installed in the lifting guide groove; the connecting frame 51 is connected to the screw nut on the horizontal screw pair, and the two ends of the flattening roller 3 are rotatably connected to the screw nuts on the lifting screw pair.

[0036] The connecting frame 51 is used to integrate the lifting guide rail 53 and the lifting transmission mechanism 52 into a lifting mechanism 5 of an integral structure, and is also used to drive and connect the lifting structure 5 with the translation mechanism. The lifting mechanism 5 has a variety of structural forms, such as an "L"-shaped structure, a "T"-shaped structure or an "I"-shaped structure. As a further preferred embodiment, the connecting frame 51 is a gantry frame, and the lifting screw rod pair and the lifting guide groove are both located on the vertical frame of the gantry frame, which has a simple structure, is easy to install and maintain, and ensures that the flattening roller 3 is balanced in force.

[0037] In order to ensure the laying effect of the waterproof coiled material 9, it is necessary to manually clean the dust on the surface of the construction base before using the device to lay the waterproof coiled material 9, which is labor-intensive and wastes manpower. Preferably, the frame 1 is also provided with a floor cleaning mechanism 6, and the floor cleaning mechanism 6 is located on the side of the cross bar 22 away from the flattening roller 3. When laying the waterproof coiled material 9, the floor cleaning mechanism 6 first cleans the surface of the corresponding construction base under the frame 1, and then the utility model moves in the direction just cleaned by the floor cleaning mechanism 6 and lays the coiled material on the cleaned construction base, saving manpower and ensuring the adhesion of the waterproof coiled material 9 to the surface of the construction base.

[0038] The ground cleaning mechanism 6 can be a dust suction device, or a broom or brush that reciprocates horizontally along the axis of the cross bar 22. The construction platform is often accompanied by block structures such as pebbles and soil blocks, which are difficult to clean with a dust suction device alone. Preferably, the cleaning mechanism 6 includes a horizontal driving mechanism 61, a second horizontal guide rail 62 parallel to the cross bar 22, and a cleaning brush 63 horizontally connected to the horizontal driving mechanism 61; the bristles of the cleaning brush 63 are in contact with the ground; the horizontal driving mechanism 61 can drive the cleaning brush 63 to reciprocate in a straight line along the length direction of the second horizontal guide rail 62. The cleaning brush 63 can clean foreign matter such as soil blocks, pebbles and dust. The cleaning brush 63 swings back and forth to sweep foreign matter on the surface of the construction platform to both sides, thereby improving the cleanliness of the surface of the construction platform below the device.

[0039] The horizontal driving mechanism 61 can be an automatic push rod or a linear transmission structure driven by a motor. The linear transmission mechanism can be a gear rack structure, a screw rod pair structure or a sprocket chain structure. Specifically, the second horizontal guide rail 62 is a guide rod 621 installed on the frame 1, and a second sliding sleeve 622 is slidably connected to the guide rod 621; the horizontal driving mechanism 61 includes a first motor 611, a driving gear 612 drivingly connected to the output shaft of the first motor 611, and a rack 613 located on the second sliding sleeve 622; the output shaft of the first motor 611 is arranged in the up and down direction, and the driving gear 612 and the rack 613 are meshed; the cleaning brush 63 is installed at the bottom of the second sliding sleeve 622. The first motor 611 drives the driving gear 612 to reciprocate, the first driving gear 612 meshes with the rack 613 and causes the rack 613 to reciprocate along the axial direction of the guide rod 621, and the rack 613 drives the sliding sleeve 622 and the cleaning brush 63 to reciprocate synchronously, thereby removing impurities on the surface of the construction base where the waterproof membrane is to be laid. The driving gear 612 can be a complete gear or a fan-shaped gear.

[0040] The above is a specific implementation method of the utility model. It can be seen from the implementation process that the utility model provides a waterproof coiled material paving device. By setting a height-adjustable, horizontally reciprocating flattening roller, the paving flatness of the waterproof coiled material is improved, so that the waterproof coiled material is tightly laid on the surface of the construction base plate, and the quality of the waterproof coiled material is improved. The height-adjustable flattening roller makes the device suitable for the flattening and paving of waterproof coiled materials of different thicknesses. By setting a telescopic push rod to adjust the relative position of the two sliding sleeves on the cross bar, the device is suitable for the paving of waterproof coiled materials of different widths. By setting a ground cleaning mechanism, the corresponding construction base surface under the frame is cleaned before paving the waterproof coiled material, so as to prevent dust from affecting the attachment effect of the waterproof coiled material and improve the paving quality of the waterproof coiled material.
