Description

TECHNICAL FIELD

[0002] With the acceleration of urbanization and the continuous development of building technology, the proportion of high-rise buildings in the city is getting higher and higher, and the waterproofing engineering of high-rise buildings is one of the basic requirements to ensure the quality and safety of buildings. Therefore, it is of wide market demand and practical application value to conduct in-depth research on the laying technology of SBS waterproofing membrane (SBS modified bitumen waterproofing membrane) for high-rise buildings, improve the quality and reliability of waterproofing engineering. When using SBS waterproofing membrane in high-rise buildings, key technical problems such as lap, fixing and closing of the membrane need to be solved. In the construction process of SBS waterproofing membrane, hot melt method is usually used. The joint of waterproofing membrane should be treated by lap joint. In the baking process using hot melt method, the lap joint part should be appropriately overflowed with hot melt bitumen, which is called "oil out", which means that the modified bitumen binder overflows from the lap joint edge during baking. According to the relevant standards, the width of the overflowed modified bitumen binder should be at least 8mm, or not less than 5mm, so as to ensure the firmness of lap joint and waterproof effect.

[0020] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] Please see Figures 1-8 A waterproofing membrane fixing device for high-rise buildings, comprising: The traveling frame has a top for holding the waterproof membrane so that it can be unrolled on the frame. Specifically, the traveling frame carries the waterproof membrane and moves while unrolling it, laying it as it is unrolled. The waterproof membrane has a central pivot to facilitate unrolling. Hot air heater 1, also known as hot air generator, is located at the front end of the traveling frame in the direction of travel. It is used to melt the adhesive strip, i.e. asphalt paste, on the overlapping surface of the waterproof membrane by using hot air. The melted asphalt paste overlaps and is fixed on the adjacent waterproof membrane to form a seal. Intermittent continuous laying mechanism, which is set in the middle of the traveling frame, is used to unroll and flatten the waterproof membrane; And an overlap seam pressing mechanism, which uses rolling to press the overlap seam of the waterproof membrane.

[0022] Specifically, the waterproof membrane placed on the mobile frame is unrolled and flattened simultaneously. During this process, the asphalt paste on the overlapping surface of the waterproof membrane is melted by a hot air heater 1. After melting, it is laid flat and overlapped onto adjacent waterproof membranes. Then, the overlap seam pressing mechanism is used to press the overlap position of the waterproof membrane by rolling, so as to promote the connection stability. In this process, unrolling, hot air heating and flattening, and rolling and pressing are completed continuously. The process is compact and the construction efficiency is high. The hot melting operation is carried out during the unrolling process, followed by the flattening and de-hollowing steps and the rolling and pressing steps, which effectively reduces the occurrence of hollows during the laying and welding of waterproof membrane, ensures construction quality, and improves construction efficiency.

[0023] Furthermore, the vehicle frame includes a front wheel frame 2 and a rear wheel frame 3, both of which have two wheels, left and right, to form a balance structure for movement; A top frame 4 is fixedly connected between the front wheel frame 2 and the rear wheel frame 3, and a V-shaped groove 5 is arranged on the top frame 4 to accommodate the central rotating shaft of the waterproof roll, so as to support the central rotating shaft of the waterproof roll and enable the waterproof roll to rotate axially and then be unwound. In the unwinding process, due to the friction between the V-shaped groove 5 and the central rotating shaft, the waterproof roll can be prevented from being unwound excessively or unwound due to inertia. In addition, a friction clutch or other deceleration mechanism can be arranged on one side of the V-shaped groove 5 to control the unwinding force by adjusting the friction, so as to actively control the rotation of the central rotating shaft of the waterproof roll, thereby preventing the waterproof roll from being unwound excessively or unwound due to inertia. This structure is a conventional structure in the prior art, and will not be described in detail. Horizontal support beams 6 are connected between the front wheel frame 2 and the rear wheel frame 3 on both sides.

[0024] Specifically, the front wheel frame 2 and the rear wheel frame 3 form a stable frame structure with the top frame 4 and the horizontal support beams 6, so as to effectively support the waterproof roll and other mechanisms of the device.

[0025] Further, a compression roller 7 is arranged on the top frame 4 and presses the waterproof roll, and the compression roller 7 rolls relative to the waterproof roll, so as to prevent the waterproof roll from falling freely and not being wound during unwinding, thereby maintaining the stable unwinding of the waterproof roll, and also preventing the waterproof roll from being unwound excessively or unwound due to inertia.

[0026] Further, the intermittent continuous paving mechanism includes a roll flattening mechanism and an intermittent unwinding mechanism. The roll flattening mechanism is pressed on the waterproof roll and flattens the waterproof roll through rolling movement. The roll flattening mechanism rolls on the entire transverse surface of the flattened waterproof roll, and air can be discharged during rolling to prevent air pockets. The coiled material intermittent unwinding mechanism is located between the coiled material flattening mechanism and the waterproof coiled material supported on the walking frame. When the coiled material flattening mechanism is pressed on the waterproof coiled material, the coiled material intermittent unwinding mechanism forms a fixed end of the waterproof coiled material laid on the base surface. The coiled material intermittent unwinding mechanism has two states through the pendulum swinging action in the front and back directions: one is to continuously support the downward waterproof coiled material to unwind during the front swinging process, which is equivalent to pulling out the coiled material to unwind during the front swinging process. During this process, the unwinding speed is controlled through the V-shaped groove 5, the friction clutch, the pressing roller 7 and other structures to avoid excessive unwinding of the waterproof coiled material or inertial unwinding. At the same time, the walking frame is in a stopped state. The waterproof coiled material in the natural falling state is flattened on the base surface by the coiled material flattening mechanism. This process makes the waterproof coiled material relaxed and reduces the stress.

[0027] Further, the coiled material flattening mechanism includes a flattening roller 8, both ends of which are rotatably connected to the first swinging rod 9, and the middle part of the first swinging rod 9 is rotatably connected to the corresponding side of the horizontal support beam 6. It also includes a swinging driving mechanism, which drives the upper end of the first swinging rod 9 to swing to drive the flattening roller 8 to swing, so that the flattening roller 8 swings downward to press on the waterproof coiled material laid on the base surface.

[0028] Specifically, the swinging driving mechanism drives the upper end of the first swinging rod 9 to swing to drive the flattening roller 8 to swing. When the lower end of the first swinging rod 9 swings upward away from the base surface position, it is in a state of disengagement, which is convenient for the overall movement and transfer of the device. When the lower end of the first swinging rod 9 swings downward to press on the waterproof coiled material laid on the base surface, the flattening roller 8 rolls on the surface of the waterproof coiled material to promote flattening and air exhaust, avoiding the problem of air drumming, as the walking frame moves and the waterproof coiled material is continuously unwound and flattened on the base surface.

[0029] Further, the swing driving mechanism comprises a fixed slide rod 10 fixedly connected to the inner side of the rear wheel frame 3, a slide sleeve 11 sleeved on the fixed slide rod 10, the slide sleeve 11 sliding on the fixed slide rod 10, a transmission rod 12 connected between the outer side surface of the slide sleeve 11 and the upper end of the first swing rod 9, both ends of the transmission rod 12 being rotatably connected with the slide sleeve 11 and the first swing rod 9, and a first telescopic hydraulic cylinder 13 fixedly connected to the rear wheel frame 3 and fixedly connected between the telescopic end of the first telescopic hydraulic cylinder 13 and the slide sleeve 11.

[0030] Specifically, under the drive of the first telescopic hydraulic cylinder 13, the slide sleeve 11 slides on the fixed slide rod 10, and in turn drives the transmission rod 12 to push the upper end of the first swing rod 9 to swing.

[0031] Further, the intermittent coiled material unwinding mechanism comprises a swing roller 14, both ends of the swing roller 14 being rotatably connected with a second swing rod 15, the middle part of the second swing rod 15 being rotatably connected to the horizontal support beam 6, the upper end of the second swing rod 15 being provided with a second telescopic hydraulic cylinder 16, the sleeve of the second telescopic hydraulic cylinder 16 being rotatably connected to the front wheel frame 2, and the telescopic end of the second telescopic hydraulic cylinder 16 being rotatably connected to the upper end of the second swing rod 15.

[0032] Specifically, in the case that the distance between the waterproof coiled material and the flattening roller 8 remains unchanged or changes little (the thickness of the coiled material becomes thinner), the second swing rod 15 supports the swing roller 14 to swing and bend the waterproof coiled material, which unwinds the waterproof coiled material in the process, and the swing of the second swing rod 15 is driven by the extension and retraction of the telescopic end of the second telescopic hydraulic cylinder 16. When the swing roller 14 is separated from the waterproof coiled material, the unwound part of the waterproof coiled material freely falls and is laid flat on the base surface. In the whole process, the process of unwinding the waterproof coiled material, the swing roller 14 separating from the waterproof coiled material, the coiled material relaxing, and the coiled material naturally laying flat on the base surface reduces stress and avoids the tensile stress of the waterproof coiled material causing deformation and hollowing after welding in the later stage.

[0033] Further, the hot air heater 1 is provided with an air supply cylinder 17, and the air supply port of the air supply cylinder 17 is arranged below the swing roller 14. In the whole operation process of the intermittent continuous laying mechanism, the waterproof coiled material is unwound, pulled, relaxed, and laid flat on the base surface, and is in continuous movement, and the arrangement position of the air supply port of the air supply cylinder 17 remains unchanged in the process to heat the lap joint position of the continuously moving waterproof coiled material, thereby ensuring the continuity of the process in the use of the device.

[0034] Further, the lap joint pressing mechanism comprises a support horizontal plate 18 horizontally connected to the rear wheel frame 3, a pressing roller 19 arranged below the support horizontal plate 18 and used to press on the lap joint, the pressing roller 19 being rotatably supported by a support frame, a guide rod 20 arranged at the top of the support frame of the pressing roller 19, the guide rod 20 penetrating through and sliding on the support horizontal plate 18, and a compression spring 21 arranged between the support frame of the pressing roller 19 and the support horizontal plate 18.

[0035] Specifically, the support horizontal plate 18 cooperates with the guide rod 20 to support the pressing roller 19, and the pressing roller 19 is pressed on the waterproof roll and rolled by the elasticity of the compression spring 21 to compact the lap joint. In the process of pushing the pressing roller 19 by the compression spring 21, the guide rod 20 slides on the support horizontal plate 18 to play a guiding and supporting role. The support horizontal plate 18 can be designed as a detachable structure on the rear wheel frame 3, such as being fixedly connected by bolts, so that the pressing roller 19 can be collected after the device is used, facilitating the movement and transfer of the device.

[0036] Further, a plurality of inclined strip protrusions 22 are continuously arranged on the lap joint part of the pressing roller 19, the plurality of inclined strip protrusions 22 being uniformly distributed in the circumferential direction of the pressing roller 19, a glue blocking head 23 is arranged above the lap joint part of the pressing roller 19, and an annular groove 24 is arranged above the lap joint part of the pressing roller 19 on the glue blocking head 23 to accommodate the molten adhesive overflowed from the lap joint part.

[0037] Specifically, when the pressing roller 19 rolls on the lap joint, the plurality of inclined strip protrusions 22 continuously press on the lap joint, and the inclination of the inclined strip protrusions 22 is arranged such that the position of the inclined strip protrusions 22 inside the lap joint first contacts the lap joint position. In the rolling process of the pressing roller 19, the inclined strip protrusions 22 gradually press on the lap joint in the direction of the outside of the lap joint along the inclined direction of the inclined strip protrusions 22. In this process, the molten bitumen paste is extruded to the joint position outside the lap joint, i.e., the edge part, so that the hot melt asphalt overflowed from the lap joint, i.e., so-called “oiling”, is controlled. According to the relevant standard, the width of the overflowed modified asphalt binder should be at least 8 mm or not less than 5 mm, so as to ensure the firmness of the lap joint and the waterproof effect. Therefore, the glue blocking head 23 at the end position of the pressing roller 19 is used to block the excessive overflow of the hot melt asphalt, and the annular groove 24 is used to accommodate the molten adhesive overflowed from the lap joint part, i.e., the hot melt asphalt, so as to control the overflow amount and size of the hot melt asphalt and ensure the sealing quality at a higher standard.

[0038] In summary, the device makes waterproofing material unroll on the walking frame, and carries out subsequent laying of the waterproofing material. While laying, the intermittent continuous laying mechanism flattens the waterproofing material while unrolling it. In the whole process, the hot air heater melts the adhesive tape on the lap joint surface of the waterproofing material, so as to further realize hot melt connection through the subsequent lap joint pressing mechanism to press the lap joint position of the waterproofing material, avoid the problem of too large air gap in the laying of the waterproofing material, and realize continuous, fast and efficient fixed construction of the waterproofing material of high-rise buildings.

[0039] The foregoing merely illustrates some exemplary embodiments of the present application, no doubt numerous modifications can be made by those skilled in the art without departing from the spirit and scope of the present application. Therefore, the above drawings and descriptions should not be understood as limiting the scope of the present application.
