Description

Technical Field

[0001] This solution relates to the field of waterproofing equipment technology, and in particular to a building waterproofing structure. Background Technology

[0002] In the construction industry, waterproofing is a crucial aspect of ensuring the lifespan and functionality of buildings. Existing waterproofing structures, such as waterproof roller shutters, present numerous problems during use. Firstly, the roller shutter's roller shaft limiting structure is not flexible enough, failing to effectively control the shutter's raising and lowering direction. This can easily lead to loss of control or jamming during operation, affecting ease of use and waterproofing effectiveness. Secondly, the sealing performance of the waterproofing structure is poor, especially at the connections between the roller shutter and the casing, as well as at the fixed ends, making it difficult to achieve a proper seal. This allows rainwater to easily seep in, reducing the waterproofing effect and failing to meet practical usage requirements.

[0003] Therefore, a new building waterproofing structure is needed to solve the problem of inflexible roller shutter shaft limiting in existing building waterproofing structures and to achieve flexible control of the roller shutter's lifting direction. Summary of the Invention

[0004] To address the aforementioned issues, this solution provides a waterproof building structure with flexible roller shutter shaft limits, enabling flexible control of the roller shutter's lifting and lowering direction.

[0005] To achieve the above objectives, the technical solution adopted in this plan is: a building waterproofing structure, including a control unit and a fixing unit;

[0006] The control unit has a roller inside its housing that winds the shutter. Bearings are installed at both the upper and lower ends of the roller. A gear is sleeved on the outside of the upper bearing. A limiting component is provided on the side of the gear. The limiting component mechanically locks the gear in both forward and reverse directions.

[0007] Furthermore, the limiting assembly includes a fixing part, a control rod, and a limiting part;

[0008] The fixing part is fixedly installed on the housing, and the middle of the limiting part is rotatably connected to the fixing part. The first control rod and the second control rod pass through the fixing part and are inserted into the housing, driving the control gear on one side of the limiting part.

[0009] Furthermore, the surface of the limiting part that contacts the gear is a pin with protrusions at both ends, and the surfaces of the pins at both ends facing each other are inclined surfaces;

[0010] The rotating rod of the upper bearing is exposed at the top of the housing, and the rotating rod can be fitted with a wrench on the top of the machine for auxiliary rotation.

[0011] Furthermore, the housing is arranged around the roller shaft, and a curtain outlet is provided on one side. A first sealing strip is fixed on one side of the curtain outlet, and a number of first loose nuts that fix the first sealing blocks are connected to the other side by threads. The distance between the first sealing blocks and the first sealing strip is controlled by adjusting the first loose nuts, so as to achieve sealing of the side of the roller shutter.

[0012] Furthermore, a guide plate is provided on the side of the roller near the curtain opening. The guide plate is fixed to the top of the housing and aligned with the curtain opening to limit the entry and exit angle of the roller blind. When the roller blind is open, it is limited to the fixing unit.

[0013] Furthermore, the fixing unit includes a limiting post, a fixing end, and a water baffle;

[0014] The water baffle includes an L-shaped first limiting plate and a second limiting plate; the bottom of the first limiting plate is fixed to the ground on the horizontal plane, a fifth loosening nut is provided at the top, and a limiting post is hinged to the vertical plane.

[0015] Furthermore, the water baffle is respectively attached to the shell and the fixed end on both sides;

[0016] The fifth nut has a threaded connection limiting member at the top. The limiting member includes a threaded connection end that is threadedly connected to the fifth nut and a limiting protrusion that protrudes outward. The second limiting plate is limited by changing the direction of the limiting protrusion.

[0017] Furthermore, the limiting post is hinged to a support post on its back, and a liftable baffle is slidably connected to its top. A second slack nut passes through the limiting post to lock the baffle, and the height of the baffle can be changed by adjusting the tightness of the second slack nut.

[0018] Furthermore, the fixed end includes a fixed post and a fixed plate. One side of the fixed plate is fixed to the wall, and the other side is fixed with a second sealing strip, which faces the fixed post.

[0019] Furthermore, the fixing column is threaded with several third loose nuts that are fixed with the second sealing block. By adjusting the third loose nuts, the distance between the second sealing block and the second sealing strip can be controlled to achieve sealing of the side of the roller shutter.

[0020] In summary, this solution has the following advantages:

[0021] The control unit provided by this solution can limit the gear in different directions, thereby flexibly controlling the forward and reverse rotation of the upper bearing. This makes the raising and lowering operation of the roller blind more precise and reliable, avoiding loss of control or jamming during the raising and lowering process, and greatly improving the ease of use.

[0022] The control unit provided by this solution allows for adjustment of the sealing distance at the curtain outlet of the housing through the cooperation of a first sealing strip, a first tightening nut, and a first sealing block, achieving good side sealing after the roller shutter is fully extended. At the fixed end, the cooperation of a second sealing strip, a third tightening nut, and a second sealing block enables the limiting and sealing of the roller shutter end, effectively preventing rainwater from seeping in from the connection between the roller shutter and the housing and the fixed end, significantly improving the waterproofing effect of the building's waterproof structure.

[0023] The limiting posts provided in this solution adopt a triangular support structure, which has strong stability and can effectively support the roller blind, preventing it from shaking or deforming during use. At the same time, the adjustable baffle design on the support post plays a good limiting role during the raising and lowering of the roller blind, further ensuring the normal use and structural stability of the roller blind.

[0040] The present solution will be further described below with reference to the accompanying drawings and embodiments:

[0041] Example 1:

[0042] A type of building waterproofing structure, such as Figure 1-9 As shown, it includes a control unit 100 and a fixing unit 200. The control unit 100 is used to control the opening and closing of the roller blind 121, and the fixing unit 200 is used to limit the roller blind 121 in the open state.

[0043] The control unit 100 includes a roller 120 disposed within a housing 110. The roller 120 is used to wind the roller blind 121, and bearings are installed at both its upper and lower ends, namely an upper bearing 131 and a lower bearing 132. A gear 1311 is sleeved on the outer side of the roller 120, and a limit assembly 140 is connected to the housing 110 on the side of the gear 1311.

[0044] The limiting assembly 140 includes a fixing part 141, a control rod 142, and a limiting part 143. The fixing part 141 is fixedly mounted on the housing 110. The first control rod 1421 and the second control rod 1422 pass through the fixing part 141, are inserted into the housing 110, and are respectively fixed on both sides of the limiting part 143. The middle of the limiting part 143 is rotatably connected to the fixing part 141. The side of the limiting part 143 near the gear 1311 is shaped like a pin with protruding ends, and the opposing surfaces of the two pins are beveled. In this configuration, the limiting part 143 achieves mechanical locking of the gear 1311 for both forward and reverse rotation. Specifically, when the first control lever 1421 is pushed into the housing 110 and the second control lever 1422 is pulled out, the limiting part 143 is inserted into the gear 1311 by the pin on the outside of the gear 1311. At this time, one side of the gear 1311 is limited by the limiting part 143, so that the gear 1311 can only rotate forward. Conversely, when the second control lever 1422 is pushed into the housing 110 and the first control lever 1421 is pulled out, the limiting part 143 is inserted into the gear 1311 by the pin on the inside of the gear 1311. At this time, the other side of the gear 1311 is limited by the limiting part 143, so that the gear 1311 can only rotate in reverse.

[0045] A rotating rod 1312 is provided above the upper bearing 131. The rotating rod 1312 protrudes from the housing 110. During operation, a top wrench adapted to the rotating rod can be inserted for auxiliary rotation.

[0046] The housing 110 is arranged around the roller 120, with a curtain outlet 111 on one side. A first sealing strip 1111 is fixed to one side of the curtain outlet 111, and several first tightening nuts 112 are threadedly connected to the other side. A first sealing block 1121 is fixed to the top of the first tightening nuts 112. The distance between the first sealing block 1121 and the first sealing strip 1111 can be controlled by adjusting the first tightening nuts 112. When the roller shutter 121 is fully extended, the first sealing block 1121 is made to fit against the first sealing strip 1111 by adjusting the first tightening nuts 112, thereby achieving a seal on the side of the roller shutter 121.

[0047] A guide plate is provided on the side of the roller 120 near the curtain outlet 111. The guide plate is aligned with the curtain outlet 111 and is used to limit the entry and exit angle of the roller blind 121. The guide plate is fixed by a connecting rod at the top of the housing 110.

[0048] The fixing unit 200 includes a limiting post 210, a fixing end 220, and a baffle plate 230. After being pulled out, the roller shutter 121 is installed on the fixing end 220 via the limiting post 210. Several limiting posts 210 are arranged between the housing 110 and the fixing end 220. The top of the support post 211 is installed in the middle section of the back of the limiting post 210, and the bottom is fixed to the ground, forming a triangular support structure. A liftable baffle 212 is slidably connected to the top of the limiting post 210, and the baffle 212 is used to limit the pulled-out roller shutter 121. A second tension nut 213 passes through the limiting post 210 to lock the baffle 212. The height of the baffle 212 is adjusted by adjusting the tightness of the second tension nut 213. In the initial state, the baffle 212 is in the lowest position and is fixed to the limiting post 210 by the second tension nut 213. The roller shutter 121 can pass between the baffle 212 and the limiting post 210. When it is necessary to retract the roller shutter 121, the baffle 212 is adjusted to the highest position by adjusting the second tension nut 213, and then the rotating rod 1312 can be rotated to retract the roller shutter 121.

[0049] The fixed end 220 includes a fixed plate 221 and a fixed post 222. One side of the fixed plate 221 is fixed to the wall, and the other side is fixed with a second sealing strip 2211. The second sealing strip 2211 faces the fixed post 222. Several third loosening nuts 2221 are threaded onto the fixed post 222. A second sealing block 22211 is fixed to the top of the third loosening nuts 2221. By adjusting the third loosening nuts 2221, the distance between the second sealing block 22211 and the second sealing strip 2211 can be controlled, thereby achieving the limiting and sealing of the roller shutter 121. By controlling the screw-in depth of the third loosening nuts 2221, it can adapt to roller shutter 121 materials of different thicknesses to ensure the sealing effect. The first loosening nut 112 and the third loosening nut 2221 have the same function.

[0050] The water baffle 230 is fixed to the bottom of the limiting post 210, and the two sides of the water baffle 240 are respectively fixed to the housing 110 and the fixed end 220. The bottom of the water baffle 240 is fixed to the ground. When the roller shutter 121 is fixed to the fixed end 220, the roller shutter 121 is in contact with the water baffle 230, and the water baffle 230 serves to block the water flow at the bottom of the roller shutter 121.

[0051] Further explanation based on its usage mechanism:

[0052] S1, Pre-installation

[0053] The housing 110 of the control unit 100 is connected to the building wall or top structure via the fixing part 141 to ensure that the housing 110 is stable.

[0054] A limiting post 210 and a supporting post 211 are fixed at a preset position on the ground between the housing 110 and the fixed end 220, and are connected to the ground by expansion bolts or concrete pouring. The fixing post 222 of the fixed end 220 is fixed to the building wall or a designated position by bolts. One side of the fixing plate 221 is connected to the wall, and the second sealing strip 2211 on the other side is directly opposite the fixing post 222.

[0055] In the initial state, the second tension nut 213 is adjusted to position the baffle 212 at the lowest point of the support column 211 and fixed, ensuring that the roller shutter 121 can freely pass between the baffle 212 and the support column 211. At the same time, the limiting part 143 of the control unit 100 is in an unlocked state, that is, neither the first control lever 1421 nor the second control lever 1422 is fully pushed into the housing 110, and the pin of the limiting part 143 is not inserted into the gear 1311.

[0056] S2, Use of waterproof structure

[0057] When the roller shutter 121 needs to be unfolded, push the first control lever 1421 into the housing 110 and simultaneously pull out the second control lever 1422, causing the limiting part 143 to rotate around the fixed part 141. The pin near the outside of the gear 1311 is inserted between the teeth of the gear 1311. At this time, one side of the gear 1311 is limited by the limiting part 143, and the gear 1311 can only rotate in the forward direction. Put the top wrench onto the rotating rod 1312 and rotate the rotating rod 1312 clockwise. The roller 120 rotates in the forward direction to unfold the roller shutter 121 until the roller shutter 121 completely covers the area to be waterproofed and extends to the fixed end 220.

[0058] After the roller blind 121 is fully extended, the first loosening nut 112 on the side of the curtain opening 111 of the rotating housing 110 pushes the first sealing block 1121 toward the first sealing strip 1111 through threaded transmission until the first sealing block 1121 is tightly attached to the first sealing strip 1111, eliminating the gap between the side of the roller blind 121 and the curtain opening 111, and achieving a waterproof seal.

[0059] Adjust the third loosening nut 2221 on the fixing column 222 to move the second sealing block 22211 toward the second sealing strip 2211 until the second sealing block 22211 and the second sealing strip 2211 are in contact, thereby limiting and sealing the end of the roller shutter 121.

[0060] S3, Close the waterproof structure

[0061] When the roller shutter 121 needs to be retracted, first adjust the second loosening nut 213, raise the baffle 212 to the highest position of the support column 211 and fix it.

[0062] Then, the first loosening nut 112 and the third loosening nut 2221 are adjusted in the opposite direction to increase the distance between the first sealing block 1121 and the first sealing strip 1111, as well as the distance between the second sealing block 22211 and the second sealing strip 2211.

[0063] Then, the second control lever 1422 is pushed into the housing 110, while the first control lever 1421 is pulled out. The pin on the other side of the limiting part 143 is inserted between the teeth of the gear 1311, restricting the gear 1311 from rotating in the opposite direction. By turning the rotating rod 1312 counterclockwise with the top wrench, the roller 120 rotates in the opposite direction to roll up the roller shutter 121 until the roller shutter 121 is completely retracted into the housing 110.

[0064] Example 2

[0065] The difference between this embodiment and Embodiment 1 is that, as Figure 10-13 As shown, the water baffle 230 adopts a split structure, including a first limiting plate 231 and a second limiting plate 232; the limiting post 210 is movably connected to the first limiting plate 231 and the support post 211 respectively by a hinge.

[0066] The first limiting plate 231 has an L-shaped plate structure. A fourth loosening nut 2311 and a fifth loosening nut 2312 are provided on its bottom surface. The fourth loosening nut 2311 is rigidly connected to the ground via expansion screws. The top of the fifth loosening nut 2312 is connected to a limiting member 2313 via an internal thread. The limiting member 2313 includes a threaded connection end 23131 and an outwardly protruding limiting protrusion 23132. By rotating the threaded connection end 23131 within the fifth loosening nut 2312, the orientation of the limiting protrusion 23132 is changed, thereby loosening and limiting the second limiting plate 232.

[0067] The vertical side of the first limiting plate 231 facing the roller shutter 121 is used in conjunction with the second limiting plate 232, while the other side is hinged to the limiting post 210 via the first hinge 214; the back of the limiting post 210 is hinged to the support post 211 via the second hinge 215. In the non-working state, the support post 211 and the limiting post 210 can be rotated and folded to fit against the first limiting plate 231, facilitating equipment storage and effectively saving space.

[0068] The second limiting plate 232 is also an L-shaped plate structure. The lengths of its two plates are the same as the corresponding plate lengths of the first limiting plate 231, while the width of its two plates is less than the distance from the L-shaped bend of the first limiting plate 231 to the limiting member 2313. During the pre-installation stage of the equipment, the first limiting plate 231 is firmly fixed to the ground using the fourth loosening nut 2311. At this time, the second limiting plate 232 is placed against the first limiting plate 231. When the roller blind 121 is unfolded, the second limiting plate 232 is inverted so that one plate surface is parallel to the vertical plate surface of the first limiting plate 231, and the other plate surface faces the limiting member 2313. By rotating the limiting member 2313, the limiting protrusion 23132 is rotated and relatively fitted against the second limiting plate 232. The second limiting plate 232 is tightly fitted against the roller blind 121 and limits the roller blind 121 between itself and the first limiting plate 231, thereby achieving effective fixation and limiting of the roller blind 121.

[0069] The baffle plate 230 provided in this embodiment not only limits the position of the rolled-up curtain 121 in the unfolded state, but also has good sealing performance.

[0070] In summary, the control unit provided in this application can limit the gear in different directions, thereby flexibly controlling the forward and reverse rotation of the upper bearing, making the raising and lowering operation of the roller blind more precise and reliable, avoiding loss of control or jamming during the raising and lowering process of the roller blind, and greatly improving the ease of use.

[0071] The control unit provided in this application, at the curtain outlet of the housing, through the cooperation of the first sealing strip, the first tightening nut and the first sealing block, can adjust the sealing distance according to actual needs, and achieve good side sealing after the roller shutter is fully pulled out; at the fixed end, through the cooperation of the second sealing strip, the third tightening nut and the second sealing block, the end of the roller shutter is limited and sealed, effectively preventing rainwater from seeping in from the connection between the roller shutter and the housing and the fixed end, and significantly improving the waterproof effect of the building waterproof structure.

[0072] The limiting post provided in this application adopts a triangular support structure, which has strong stability and can effectively support the roller blind, preventing it from shaking or deforming during use. At the same time, the liftable baffle design on the support post plays a good limiting role during the raising and lowering of the roller blind, further ensuring the normal use and structural stability of the roller blind.
