Description

Technical Field

[0001] This invention relates to the field of waterproof material transportation technology, specifically to a device for storing, handling, and conveying waterproof materials on the top floor of buildings. Background Technology

[0002] In building construction, the relationship between the rooftop and waterproofing materials is close and crucial. The selection of waterproofing materials must match the design and materials of the rooftop to ensure good waterproofing performance. For example, different types of roofs, such as flat roofs, pitched roofs, or green roofs, have different requirements for waterproofing materials, and appropriate waterproofing materials must be selected based on the characteristics of the rooftop. Waterproofing materials are mainly divided into roll materials, waterproof coatings, sealants, and rigid waterproofing materials. Roll materials include asphalt waterproofing rolls and polymer waterproofing rolls, suitable for waterproofing roofs and underground projects.

[0003] Waterproof membranes are easily deformed by compression during transportation or storage, affecting their flatness after unfolding. A storage device for waterproof membranes during transportation, disclosed in Chinese Patent Application Publication CN207791504U, uses a piston rod inserted from below into a paper tube inside the waterproof membrane, and a fixing rod inserted from above into the same paper tube, thus securing the waterproof membrane. This provides better fixation and prevents it from rolling or tipping over during transportation due to bumps. Furthermore, the waterproof membranes maintain a certain distance from each other to prevent adhesion. Additionally, the base plate can rotate relative to the base for easy removal of the waterproof membrane. When removing the membrane, air is released through a valve on pipe number one, causing the piston rod to enter the piston cylinder under gravity, raising the telescopic rod, and disengaging the piston rod and fixing rod from the paper tube. This device facilitates the fixing and removal of the waterproof membrane, and its simple structure makes it easy to use.

[0004] The aforementioned patent utilizes a piston rod and fixing rod design to provide excellent fixation when the waterproof membrane is placed vertically, preventing it from rolling or tipping over during transportation. However, in practical applications, it has been found that a certain gap exists between the piston rod / fixing rod and the membrane. As the membrane sways within this gap, its weight may unevenly concentrate at a single point at the bottom, causing excessive localized pressure on the bottom edge and increasing the risk of damage. Furthermore, the aforementioned patent requires the waterproof membrane to be tilted before being moved by two workers. During this process, the weight of the waterproof membrane is concentrated at its bottom edge, resulting in excessive pressure and making the bottom edge susceptible to damage. Therefore, we provide a storage and transportation device for rooftop waterproofing materials in building construction to address these issues. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a storage and transportation device for waterproofing materials on the top floor of a building. While adjusting the waterproofing membrane to a vertical position, it can fix it from the inside and also prevent the weight of the waterproofing membrane from being concentrated on its bottom edge when it is taken out, which would make the bottom edge of the waterproofing membrane easily damaged.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a storage and transportation device for waterproof materials on the top floor of a building, comprising a box, wherein the box includes a storage box, a rotating fixing mechanism is provided inside the storage box, and a limiting mechanism for limiting the rotating fixing mechanism is also provided inside the storage box.

[0007] The rotating fixing mechanism includes a fixed base fixed to the bottom wall of the storage box, a rotating shaft rotatably connected to the fixed base, a support rod fixed to one end of the rotating shaft, a gear fixed to the other end of the rotating shaft, a fixing plate fixed to the side of the support rod, an airbag fixed to the fixing plate, a mounting bracket slidably connected to the side of the support rod fixed to the other side of the airbag, a toothed plate meshing with the gear fixed to the side of the mounting bracket near the fixed base, a cavity opened in the inner wall of the support rod, a connecting pipe A connecting the airbag and the cavity fixed to the airbag and the support rod, an installation groove opened in the side of the support rod, an inflatable airbag fixed to the installation groove, and a connecting pipe B connecting the inflatable airbag and the cavity fixed to the support rod.

[0008] One end of the support rod has a connecting cavity that communicates with the cavity. A positioning spring is fixed inside the connecting cavity. The other end of the positioning spring is fixed with a sealing plug that slides in contact with the connecting cavity. A connecting rod that passes through the support rod is fixed on the other side of the sealing plug.

[0009] The limiting mechanism includes a limiting shell fixed to the bottom wall of the storage box, a compression spring fixed to the inner wall of the limiting shell, a sliding column fixed to the other end of the compression spring, a ball rotatably connected to the other end of the sliding column, a sliding groove opened on the side of the limiting shell, and a sliding rod fixed to the side of the sliding column.

[0010] Furthermore, a protective pad is fixed to the side of the mounting bracket away from the airbag, and the outer contour of the protective pad is cylindrical.

[0011] By adopting the above technical solution, the protective pad is made of rubber. The protective pad can provide a certain cushioning effect for the waterproof membrane, preventing the bottom of the waterproof membrane from being subjected to severe vibration.

[0012] Furthermore, a sealing gasket is fixed on the side of the sealing plug that contacts the connecting cavity, and the sealing gasket is externally disposed on the side of the connecting rod.

[0013] By adopting the above technical solution, the sealing gasket can further improve the sealing effect between the sealing plug and the cavity, and prevent air leakage between the sealing plug and the connecting cavity.

[0014] Furthermore, a rotating groove is provided on the side of the support rod, and a rotating rod is rotatably connected inside the rotating groove.

[0015] By adopting the above technical solution, when the waterproof membrane is inserted into the support rod, the rotating rod can support the waterproof membrane, allowing the waterproof membrane to slide on the rotating rod. The rotating rod will rotate on the rotating groove. The cooperation between the rotating groove and the rotating rod can reduce the friction between the waterproof membrane and the support rod, making the waterproof membrane more smoothly inserted into the support rod.

[0016] Furthermore, the thickness of the inflatable bladder is less than the depth of the mounting groove.

[0017] By adopting the above technical solution, the thickness of the air bladder is less than the depth of the installation groove. When the waterproof membrane is inserted into the horizontal support rod, the waterproof membrane does not come into contact with the air bladder, thus allowing the waterproof membrane to be smoothly inserted into the support rod and avoiding the air bladder from obstructing the insertion of the waterproof membrane.

[0018] Furthermore, the side of the limiting shell is provided with a limiting groove that communicates with the sliding groove, and the inner diameter of the limiting groove is larger than the inner diameter of the sliding rod.

[0019] By adopting the above technical solution, the slide rod can rotate into the limiting groove. At this time, the slide rod is limited by the limiting groove. The elastic force released by the compression spring will make the slide rod firmly stuck in the mounting bracket. When the slide rod is stuck in the limiting groove, the slide column does not limit the support rod. At this time, the waterproof membrane can be moved to a horizontal state by rotating the support rod.

[0020] Furthermore, the front of the storage box is hinged to a lid, a support column is fixed on the lid, a sealing strip is fixed on the side of the lid near the storage box, and a connecting component is provided on the storage box and the lid.

[0021] By adopting the above technical solutions, the lid can seal the storage box, preventing external dust and other impurities from contaminating the waterproof membrane inside the storage box. The support column can support the lid, and the sealing strip can improve the sealing between the storage box and the lid, preventing dust and other impurities from entering the storage box from the gap between the storage box and the lid.

[0022] Furthermore, the bottom surface of the storage box is fixed with four casters.

[0023] By adopting the above technical solution, the installation of casters facilitates the movement of the storage box, allowing it to be moved to a suitable location and improving the flexibility of the device.

[0024] Furthermore, the connecting assembly includes a connecting plate A fixed to the box cover, a threaded sleeve fixed to the side of the connecting plate A, a threaded rod threaded through the connecting plate A being threadedly connected to the inside of the threaded sleeve, and a connecting plate B fixed to the top surface of the storage box, with a through hole provided on the connecting plate B.

[0025] By adopting the above technical solution, the threaded rod is rotated and will move on the threaded sleeve until it moves into the through hole opened on the connecting plate B. The storage box and the box cover can be fixed together by the cooperation of the connecting plate A, the threaded rod and the connecting plate B.

[0026] Furthermore, a knob is fixed to one end of the threaded rod, and the outer contour of the knob is cylindrical.

[0027] By adopting the above technical solution, a knob is set to facilitate the rotation of the threaded rod, providing a reasonable force point for rotating the threaded rod, making it more convenient to use.

[0028] Compared with existing technologies, this rooftop waterproofing material storage and transportation device has the following advantages:

[0029] Beneficial effects:

[0030] I. This invention facilitates the removal or storage of waterproof membrane using a horizontally positioned support rod. When storing the waterproof membrane, the membrane compresses the protective pad, mounting bracket, and airbag, causing the gas inside the airbag to sequentially enter the interior of the airbag through connecting pipe A, cavity, and connecting pipe B. This causes the airbag to undergo elastic deformation, thereby fixing the waterproof membrane from within and preventing large gaps between the support rod and the waterproof membrane, which could lead to the membrane shaking.

[0031] II. In this invention, during the compression of the protective pad, mounting bracket, and airbag by the waterproof membrane, the mounting bracket will slide on the support rod, causing the mounting bracket to rotate via a toothed plate. The rotating gear will then drive the rotating shaft and support rod to rotate until the support rod drives the connecting rod to abut against the ball. At this point, the support rod continues to rotate, and the elastic force released by the deformation of the compression spring will drive the sliding column and the ball to compress the connecting rod, causing the connecting rod to move the sealing plug within the connecting cavity. This will push the gas inside the connecting cavity sequentially into the cavity, the connecting tube B, and the airbag. The airbag continues to expand, thereby further improving the fixing effect of the waterproof membrane. At the same time, the sliding column inserted into the support rod can also limit the support rod, preventing it from rotating and completing the vertical fixing of the support rod. Through the cooperation of the above components, the waterproof membrane can be fixed from the inside while being adjusted to a vertical position, while avoiding the weight of the waterproof membrane being concentrated on its bottom edge when it is removed, which would make the bottom edge of the waterproof membrane easily damaged.

[0032] II. This invention facilitates the rotation of the threaded rod by setting a knob, providing a reasonable point of force for rotating the threaded rod. When the threaded rod is rotated, it will move on the threaded sleeve until it moves into the through hole opened on the connecting plate B. The storage box and the lid can be fixed together by the cooperation of the connecting plate A, the threaded rod, and the connecting plate B. The lid can seal the storage box and prevent external dust and other impurities from contaminating the waterproof membrane inside the storage box. The support column can support the lid. The sealing strip can improve the sealing between the storage box and the lid and prevent dust and other impurities from entering the storage box from the gap between the storage box and the lid. The sealing gasket can further improve the sealing effect between the sealing plug and the cavity and prevent air leakage between the sealing plug and the connecting cavity.

[0033] Other advantages, objectives and features of the invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be learned from the practice of the invention.

[0048] Please see Figure 1-8 This invention provides a technical solution: a storage and transportation device for waterproofing materials on the top floor of a building, comprising a box body 1, the box body 1 including a storage box 101, a box cover 102 hinged to the front of the storage box 101 via a hinge, the box cover 102 can close the storage box 101 to improve the dustproof effect, a support column 104 fixed on the box cover 102 to support the box cover 102, a sealing strip 103 fixed on the side of the box cover 102 near the storage box 101, the sealing strip 103 can improve the sealing effect between the storage box 101 and the box cover 102, and four casters 105 fixed on the bottom surface of the storage box 101 to facilitate the movement of the device.

[0049] Please refer to this carefully. Figure 1 and Figure 7A connecting assembly 4 is provided on the storage box 101 and the box cover 102. The connecting assembly 4 includes a connecting plate A401 fixed on the box cover 102. A threaded sleeve 402 is fixed on the side of the connecting plate A401. A threaded rod 403 that passes through the connecting plate A401 is threadedly connected inside the threaded sleeve 402. A connecting plate B404 is fixed on the top surface of the storage box 101. A through hole is provided on the connecting plate B404. A knob 405 is fixed on one end of the threaded rod 403. The outer contour of the knob 405 is cylindrical. The knob 405 is provided to facilitate the rotation of the threaded rod 403 and provides a reasonable force point for rotating the threaded rod 403, making it convenient to use.

[0050] Specifically, after the lid 102 is rotated to the vertical position, the threaded rod 403 is rotated by the knob 405. The threaded rod 403 will move on the threaded sleeve 402 until the threaded rod 403 moves into the through hole opened on the connecting plate B404. The storage box 101 and the lid 102 can be fixed together by the cooperation of the connecting plate A401, the threaded rod 403 and the connecting plate B404.

[0051] Please refer to this carefully. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 The storage box 101 is equipped with a rotating fixing mechanism 2, which includes a fixing seat 201 fixed to the bottom wall of the storage box 101. A rotating shaft 202 is rotatably connected to the fixing seat 201. A support rod 203 is fixed to one end of the rotating shaft 202, and a gear 204 is fixed to the other end of the rotating shaft 202. A fixing plate 205 is fixed to the side of the support rod 203, and an airbag 206 is fixed to the fixing plate 205. A mounting bracket 207, which is slidably connected to the side of the support rod 203, is fixed to the other side of the airbag 206. The mounting bracket 207 is made of a relatively hard material. The mounting bracket 207, pushed by the waterproof membrane, can compress the airbag 206, causing the airbag 206 to deform and forcing the gas inside the airbag 206 into the cavity 210. At the same time, the mounting bracket 207 can drive the toothed plate 208 to rotate. A protective pad 217 is fixed on the side of the mounting bracket 207 away from the airbag 206. The outer contour of the protective pad 217 is cylindrical and the material of the protective pad 217 is rubber. The protective pad 217 can play a certain buffering role for the waterproof membrane and prevent the bottom of the waterproof membrane from being subjected to violent vibration.

[0052] A toothed plate 208 that meshes with a gear 204 is fixed on the side of the mounting bracket 207 near the fixing base 201. A cavity 210 is opened in the inner wall of the support rod 203. A connecting pipe A209 connecting the airbag 206 and the cavity 210 is fixed on the support rod 203. An installation groove 212 is opened on the side of the support rod 203. An inflatable airbag 213 is fixed on the installation groove 212. The thickness of the inflatable airbag 213 is less than the depth of the installation groove 212. When the waterproof membrane is inserted into the horizontal support rod 203, the waterproof membrane does not contact the inflatable airbag 213, so that the waterproof membrane can be smoothly inserted into the support rod 203. A connecting pipe B211 connecting the inflatable airbag 213 and the cavity 210 is fixed on the support rod 203.

[0053] Specifically, after the waterproof membrane is inserted into the support rod 203, it compresses the protective pad 217. The protective pad 217 then compresses the airbag 206 via the mounting bracket 207. As a result, the gas inside the airbag 206 enters the cavity 210 through the connecting pipe A209. Then, the gas inside the cavity 210 enters the inflatable bladder 213 through the connecting pipe B211, causing the inflatable bladder 213 to undergo elastic deformation. The inflatable bladder 213, which undergoes elastic deformation, adheres to the waterproof membrane, thereby fixing it from the inside of the waterproof membrane.

[0054] One end of the support rod 203 has a connecting cavity 221 that communicates with the cavity 210. A positioning spring 214 is fixed inside the connecting cavity 221. The positioning spring 214 can position the sealing plug 215. The elastic force of the positioning spring 214 is less than the elastic force of the compression spring 302. The other end of the positioning spring 214 is fixed with a sealing plug 215 that slides in contact with the connecting cavity 221. The other side of the sealing plug 215 is fixed with a connecting rod 216 that passes through the support rod 203.

[0055] A sealing gasket 218 is fixed on the side of the sealing plug 215 that contacts the connecting cavity 221. The sealing gasket 218 can further improve the sealing effect. The sealing gasket 218 is externally located on the side of the connecting rod 216. A rotating groove 219 is opened on the side of the support rod 203. A rotating rod 220 is rotatably connected inside the rotating groove 219. When the waterproof membrane is inserted into the support rod 203, the rotating rod 220 can support the waterproof membrane, allowing the waterproof membrane to slide on the rotating rod 220. The rotating rod 220 will rotate on the rotating groove 219. The cooperation between the rotating groove 219 and the rotating rod 220 can reduce the friction between the waterproof membrane and the support rod 203, allowing the waterproof membrane to be inserted into the support rod 203 more smoothly.

[0056] Specifically, when the connecting rod 216 is squeezed by the ball 304, it will slide within the support rod 203. The moving connecting rod 216 will drive the sealing plug 215 to move within the connecting cavity 221. The sealing plug 215 can push the gas inside the connecting cavity 221 into the cavity 210. Then, the gas will enter the mounting groove 212 from the cavity 210 and the connecting pipe B211. The gas inside the inflatable bladder 213 increases, and the inflatable bladder 213 will continue to deform. The inflatable bladder 213 fits more tightly with the waterproof membrane, further improving the fixing effect of the waterproof membrane.

[0057] Please refer to this carefully. Figure 2 , Figure 3 , Figure 5 and Figure 6 The storage box 101 is also provided with a limiting mechanism 3 for limiting the rotation fixing mechanism 2. The limiting mechanism 3 includes a limiting shell 301 fixed to the bottom wall of the storage box 101. A compression spring 302 is fixed to the inner wall of the limiting shell 301. A sliding column 303 is fixed to the other end of the compression spring 302. A ball 304 is rotatably connected to the other end of the sliding column 303. When the ball 304 contacts the side of the support rod 203, the compression spring 302 is in a compressed state. See the limiting mechanism 3 in the figure. A sliding groove 305 is opened on the side of the limiting shell 301. A sliding rod 306 is fixed on the side of the sliding column 303.

[0058] The side of the limiting shell 301 is provided with a limiting groove 307 that communicates with the sliding groove 305. By rotating the sliding rod 306, the sliding rod 306 can be inserted into the limiting groove 307. The inner diameter of the limiting groove 307 is larger than the inner diameter of the sliding rod 306, thereby limiting the sliding column 303 so that the sliding column 303 cannot move under the elastic force released by the compression spring 302. At this time, the sliding column 303 no longer limits the support rod 203. By rotating the support rod 203, the waterproof membrane can be moved to a horizontal state.

[0059] Working principle: The horizontal support rod 203 facilitates the removal of the waterproof membrane. The weight of the waterproof membrane is not entirely applied to its bottom edge. When storing the waterproof membrane, it is first inserted into the support rod 203, allowing it to slide on the rotating rod 220. Then, the waterproof membrane is pushed, compressing the protective pad 217, mounting bracket 207, and airbag 206. After being compressed, the gas inside the airbag 206 enters the inflatable bladder 213 sequentially through the connecting pipe A209, cavity 210, and connecting pipe B211, causing the inflatable bladder 213 to undergo elastic deformation. The elastically deformed inflatable bladder 213 gradually adheres to the waterproof membrane, thus fixing it from the inside and preventing large gaps between the support rod 203 and the waterproof membrane, which could cause the waterproof membrane to wobble. Furthermore, during the process of compressing the protective pad 217, mounting bracket 207, and airbag 206 by the waterproof membrane, the mounting bracket 207 will slide on the support rod 203, thereby causing the mounting bracket 207 to drive the gear 204 to rotate via the toothed plate 208. The rotating gear 204 will drive the rotating shaft 202 and the support rod 203 to rotate until the support rod 203 drives the connecting rod 216 to abut against the ball 304. At this time, if the support rod 203 continues to rotate, the elastic force released by the deformation of the compression spring 302 will drive the sliding column 303 and the ball 304 to compress the connecting rod 216, causing the connecting rod 216 to drive the sealing plug 215 to move within the connecting cavity 221, thereby sealing the airbag 216. The sealing plug 215 sequentially pushes the gas inside the connecting cavity 221 into the cavity 210, the connecting pipe B211, and the inflatable bladder 213. At this time, the gas inside the inflatable bladder 213 increases, and the inflatable bladder 213 will continue to expand, thereby further improving the fixing effect on the waterproof membrane. At the same time, the sliding column 303 inserted into the support rod 203 can also limit the support rod 203, preventing it from rotating, thus completing the vertical fixing of the support rod 203. Through the cooperation of the above components, the waterproof membrane can be fixed from the inside while being adjusted to a vertical state, and at the same time, it can be prevented that the weight of the waterproof membrane is concentrated on its bottom edge when it is removed, which would make the bottom edge of the waterproof membrane easily damaged.

[0060] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
