Technical Field

[0001] This application relates to the field of underground parking garage technology, and in particular to an entrance / exit structure for an underground parking garage. Background Technology

[0002] To ensure sufficient parking spaces for the ever-increasing number of cars in cities, developers are now building underground parking garages to meet the growing parking demand. Since these garages are located underground, they require entrances and exits.

[0003] Currently, most underground parking garages have entrances and exits with access channels for cars and a canopy structure above the access channels. The canopy structure includes a support structure and a cover structure installed on the support structure. The support structure is formed by support rods arranged at intervals and fixed to the walls or bottom of the access channels. The cover structure mainly consists of a cover frame made of steel pipes and a protective cover installed on the top of the cover frame.

[0004] To enhance the overall strength of the roof structure of underground parking garages, the inventors have provided an underground parking garage entrance / exit structure with a novel roof structure. Summary of the Invention

[0005] To enhance the overall strength of the underground parking garage roof structure, this application provides an underground parking garage entrance / exit structure.

[0006] An underground parking garage entrance structure includes an entrance passage, supporting walls on both sides of the entrance passage, an entrance canopy installed above the entrance passage, and a supporting structure installed on the supporting walls for supporting the entrance canopy. The entrance canopy includes a canopy frame and a rainproof panel installed above the canopy frame. The canopy frame includes multiple canopy ribs spaced apart along its width, a first supporting steel pipe running horizontally through and connecting the canopy ribs, a second supporting steel pipe running horizontally through and connecting the canopy ribs, and multiple connecting steel pipes running through and connecting the canopy frame. The supporting structure includes a first support base for supporting both ends of the first supporting steel pipe and a second support base for supporting both ends of the second supporting steel pipe. Both the first and second support bases have first embedded metal parts pre-embedded in the supporting walls.

[0007] By adopting the above technical solution, the warehouse canopy is constructed using a canopy frame arranged at intervals, and all the canopy frames are connected by a first support pipe and a second support pipe. Compared with a frame-type canopy structure, the canopy structure with a canopy frame is more robust. Simultaneously, a first support base supports a first support steel pipe, a second support base supports a second support steel pipe, and a first embedded metal part fixes the first and second support bases to the supporting wall, ensuring that the overall structure of the warehouse canopy is supported by the supporting structure, resulting in a more ideal overall structure.

[0008] Optionally, the garage roof includes a main roof connected to the supporting structure and a rear roof connected at one end to the main roof and at the other end to the garage roof slab, wherein the rear roof is connected to a second embedded metal component embedded in the garage roof slab.

[0009] By adopting the above technical solution, a second embedded metal part is provided in the rear canopy, so that the rear canopy is fixedly installed on the garage roof slab, and the rear canopy can be supported by the garage roof slab, thereby further strengthening the overall strength of the garage roof structure of the underground garage.

[0010] Optionally, an underground parking garage entrance structure further includes a flood control device, which includes two flood control slides vertically fixed to the supporting wall and arranged opposite each other, a flood control component detachably installed on the flood control slides, and a flood control base embedded in the bottom surface of the entrance passage and used to cooperate with the bottom surface of the flood control component; the flood control component includes a flood control outer sleeve and multiple flood control frame plates arranged at intervals along the height direction inside the flood control outer sleeve; the flood control frame plate located at the lowest side is located on the inner bottom surface of the flood control outer sleeve; the flood control slides have sealing grooves for sealing and sliding the ends of the flood control frame plates; the flood control outer sleeve is provided with a first joint for connecting a water pump.

[0011] By adopting the above technical solution, the flood control component is installed on the flood control base, and water is introduced into the flood control component through the first joint, causing the flood control component to expand under the action of water. Through the cooperation of the flood control frame and the flood control slide, the probability of the flood control component tipping over and swaying is reduced, so that the flood control component has the function of flood control.

[0012] Optionally, the flood control component further includes multiple support columns, and the flood control outer casing has support channels that correspond one-to-one with the support columns and are used for arranging the support columns; the bottom end of the support column abuts against the top surface of the flood control base.

[0013] By adopting the above technical solution, when water is poured into the flood control component and it expands, the support column is inserted through the support channel, which helps to improve the overall strength of the waterproof component and reduce the probability of it tipping over after being impacted.

[0014] Optionally, the flood control frame plate has a snap-fit ​​ring extending into the support channel; a snap-fit ​​structure is provided between the support column and the snap-fit ​​ring, the support column is provided with a snap-fit ​​connector, and the snap-fit ​​ring is provided with a snap-fit ​​groove for the snap-fit ​​connector to rotate and snap-fit.

[0015] By adopting the above technical solution, the snap-fit ​​joints of several support columns are connected to the snap-fit ​​grooves of the flood control frame, so that the flood control frame can be snapped onto the support columns and is not easy to shake. This makes the flood control components more stable when filled with water, and the flood control effect is more ideal.

[0016] Optionally, the flood control frame plate includes a first frame plate and a second frame plate that are horizontally slidably connected. The flood control frame plate is also provided with an elastic element that drives the first frame plate and the second frame plate to always maintain a docking state. A support hole is formed between the first frame plate and the second frame plate. The flood control component is also provided with a cam column that pushes the first frame plate and the second frame plate open. The flood control outer sleeve is also provided with a cam insertion hole for the cam column to be inserted and removed.

[0017] By adopting the above technical solution, the cam column is inserted into the support hole between the first frame and the second frame, and by rotating the cam column, the first frame and the second frame slide to both sides, and the ends of the first frame and the second frame are engaged in the sealing groove of the flood control slide, so that the fit between the flood control component and the sealing groove is more precise, thereby making the sealing effect of the flood control device more ideal.

[0018] Optionally, a storage box for storing the flood control components is installed at the front end of the storage canopy; the bottom of the storage box has an access port for taking out and putting in the flood control components; the storage box is equipped with a lifting mechanism for lifting the flood control components, the lifting mechanism including a take-up roller rotatably mounted on the storage box, a windproof cloth wound around the take-up roller, and a drive motor for driving the take-up roller to rotate; the storage box is equipped with two sets of the lifting mechanisms, the distal ends of the windproof cloth of one lifting mechanism are detachably connected to the front edge of the bottom end of the flood control components; the distal ends of the windproof cloth of the other lifting mechanism are detachably connected to the rear edge of the bottom end of the flood control components.

[0019] By adopting the above technical solution, after the flood control components are used, they can be lifted by a lifting device and placed inside the storage shed, making it more convenient to retrieve and place them. Furthermore, by using a windproof cloth, which has higher strength and more stable connection, the windproof cloth can be detachably installed at the bottom of the flood control components. When the flood control components are lowered from the storage shed, the windproof cloth can be manually removed, and the flood control components can be installed and irrigated before the windproof cloth is reinstalled. This makes the installation process more convenient and increases the efficiency of the flood control component installation work.

[0020] Optionally, the storage box is provided with a dewatering plate located below the winding roller and used for squeezing by the flood control component.

[0021] By adopting the above technical solution, when the flood control component is stored in the storage box, the lifting mechanism continues to lift the flood control component, bringing it against the water-squeezing plate, and squeezing out the water inside the flood control component through the water-squeezing plate, keeping the flood control component dry and facilitating its preservation.

[0022] Optionally, the storage box is slidably installed on the top of the storage canopy along the length of the canopy, and the bottom of the storage box is in contact with the top surface of the storage canopy; the storage canopy is provided with a sliding drive assembly for driving the storage box to slide.

[0023] By adopting the above technical solution, a drive assembly is used to slide the storage box to the center of the garage ceiling, allowing it to be stored on the ceiling, thus enhancing safety. Furthermore, by ensuring the bottom of the storage box fits snugly against the top surface of the garage ceiling, the bottom of the storage box is completely covered by the roof.

[0024] Optionally, the top of the storage box is provided with a placement opening and a placement end cap for closing the placement opening.

[0025] By adopting the above technical solution and providing a placement opening, the support column and cam column of the flood control component can be placed into the storage box after use, which facilitates the preservation of each component of the flood control component.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The warehouse ceiling is constructed using a spaced-out ceiling frame, with all frames connected by first and second support pipes. Compared to a frame-type ceiling structure, the frame-type structure offers superior strength. Furthermore, first support bases support first support steel pipes, and second support bases support second support steel pipes. First and second support bases are fixed to the supporting wall via pre-embedded metal components, ensuring the overall structure of the warehouse ceiling is well-supported and achieves a more ideal overall structure. 2. Insert the cam column into the support hole between the first frame and the second frame, and rotate the cam column to make the first frame and the second frame slide to both sides, and engage the ends of the first frame and the second frame into the sealing groove of the flood control slide, so that the fit between the flood control component and the sealing groove is more precise, thereby making the sealing effect of the flood control device more ideal; 3. Install the flood control component onto the flood control base, and then pass water into the flood control component through the first connector. This causes the flood control component to expand under the action of water. Through the cooperation of the flood control frame and the flood control slide, the probability of the flood control component tipping over and swaying is reduced, thus enabling the flood control component to have the function of flood control.

The two flood control slides 51 are respectively installed on two supporting walls 2 and arranged opposite each other. To ensure a good seal between the flood control slides 51 and the supporting walls 2, the flood control slides 51 and the supporting walls 2 are fixed with anchor bolts, and a layer of waterproof adhesive is applied between the flood control slides 51 and the supporting walls 2. Sealing grooves 511 are provided on the opposite sides of the two flood control slides 51 for the vertical sliding of the flood control component 52.

[0055] Reference Figure 8 and Figure 9 The flood control component 52 includes a flood control outer casing 521 and multiple flood control frame plates 522 arranged at intervals along the height direction within the flood control outer casing 521. The flood control outer casing 521, when filled with the medium, forms a rectangular wall. In this embodiment, five flood control frame plates 522 are provided, with the bottommost plate located at the inner bottom surface of the flood control outer casing 521. To facilitate the filling and emptying of the flood control outer casing 521 with the medium, the top of its side wall is provided with a first connector 5211 for connecting to a water supply pump and a first valve body 5212 installed on the first connector 5211 for controlling its opening and closing.

[0056] Reference Figure 8 and Figure 9 The flood control outer casing 521 has a vertically penetrating cam insertion hole 5215, and a cam post 54 is detachably installed at the cam insertion hole 5215. The flood control frame plate 522 is correspondingly provided with a support hole 5221, and at the support hole 5221, the flood control frame plate 522 is divided into a first frame plate 5222 and a second frame plate 5223 that are horizontally slidably connected.

[0057] Reference Figure 10 and Figure 11 An elastic element 5224 is provided between the first frame plate 5222 and the second frame plate 5223 to keep them in a mating state. Sliding posts 5225 are provided on both sides of the end face of the first frame plate 5222 facing the second frame plate 5223. The second frame plate 5223 has sliding insertion holes 5226 on its end face facing the first frame plate 5222 for sliding insertion of the sliding posts 5225. The elastic element 5224 is a tension spring. A first fixing ring 5227 is provided at the end of the sliding post 5225 for fixing the end of the tension spring, and a second fixing ring 5228 is provided on the bottom surface of the sliding insertion hole 5226 for fixing the other end of the tension spring. This structure ensures that the first frame plate 5222 and the second frame plate 5223 tend to remain in a mating state.

[0058] Reference Figure 8 and Figure 9 The cross-section of the support hole 5221 is elliptical, with its major axis parallel to the width direction of the flood control component 52 and its minor axis parallel to the length direction of the flood control component 52. The cross-section of the cam post 54 is consistent with that of the support hole 5221, so that the cam post 54 can be inserted into the cam insertion hole 5215 and pass through the support hole 5221.

[0059] Reference Figure 7 and Figure 9 Construction workers can separate the first frame plate 5222 and the second frame plate 5223 by rotating the cam column 54, thereby increasing the overall length of the flood control frame plate 522 and improving the sealing effect between the flood control component 52 and the flood control slide 51.

[0060] Reference Figure 7 and Figure 8 In order to improve the wear resistance of the flood control jacket 521 at the cam insertion hole 5215, a wear-resistant layer is provided on the flood control jacket 521 at the cam insertion hole 5215.

[0061] Reference Figure 8 and Figure 9The flood control component 52 also includes multiple support columns 55. The flood control outer jacket 521 has support channels 5216 that correspond one-to-one with the support columns 55 and are used for arranging the support columns 55. In this embodiment, the flood control outer jacket 521 is provided with four support channels 5216, and the four support channels 5216 are arranged at intervals along the length direction of the flood control outer jacket 521.

[0062] Reference Figure 8 and Figure 9 The flood control frame plate 522 has a snap-fit ​​ring 5229 located outside the support channel 5216, and the support column 55 is provided with a snap-fit ​​connector 551 for snap-fitting with the snap-fit ​​ring 5229.

[0063] Reference Figure 10 and Figure 12 The outer wall of the snap-fit ​​connector 551 is provided with a snap-fit ​​protrusion 552. The inner side of the snap-fit ​​ring portion 5229 is provided with a snap-fit ​​groove 52291 for the snap-fit ​​protrusion 552 to rotate and snap-fit. The snap-fit ​​ring portion 5229 is also provided with a snap-fit ​​channel 52292 that connects to and penetrates the upper and lower surfaces of the snap-fit ​​ring portion 5229.

[0064] Reference Figure 8 and Figure 9 Since the outer skin of the flood control outer jacket 521 at the support channel 5216 is located between the support column 55 and the snap ring 5229, the outer skin at this location will be squeezed every time the support column 55 is installed. Therefore, the length and outer diameter of the outer skin of the flood control outer jacket 521 at the support channel 5216 are both greater than the length and outer diameter of the support channel 5216, so that the outer skin of the flood control outer jacket 521 at the support channel 5216 can be deformed, thereby facilitating the installation on the support channel 5216.

[0065] Reference Figure 8 and Figure 9 When the support column 55 is installed in the support channel 5216 of the flood control outer casing 521, the snap joint 551 of the support column 55 can support the flood control frame plate 522, thereby improving the structural strength of the flood control component 52 in the height direction.

[0066] Reference Figure 7 The storage box 6 for storing flood control components 52 is also slidably installed on the storage canopy 3, along with a drive assembly for sliding the storage box 6. Driven by the drive assembly, the storage box 6 has a first working position on the top surface of the storage canopy 3 and a second working position located on the front side of the storage canopy 3.

The drive screw 73 is located above one of the guide rails 71, and the top of the guide rail 71 is provided with a screw support seat 711 for the drive screw 73 to be rotatably installed. There are two guide sliders 72, which are symmetrically installed on the side of the storage box 6 and cooperate with the corresponding guide rails 71.

[0068] Reference Figure 7 When the storage box 6 is in the first working position, the bottom surface of the storage box 6 is in contact with the top surface of the storage canopy 3, that is, the storage canopy 3 covers the loading and unloading opening 61 of the storage box 6, and the storage box 6 is located above the first supporting steel pipe 312. When the storage box 6 is in the second working position, the storage box 6 is located in front of the storage canopy 3, and the loading and unloading opening 61 of the storage box 6 is opened to facilitate the lowering of the flood control component 52.

[0069] Reference Figure 7 and Figure 13 The storage box 6 is equipped with a lifting mechanism for raising the flood control component 52. The lifting mechanism includes a take-up roller 81 rotatably mounted on the storage box 6, a windproof cloth 82 wound around the take-up roller 81, and a drive motor 83 for driving the take-up roller 81 to rotate.

The distal end of the windproof cloth 82 of one set of lifting mechanisms is detachably connected to the front edge of the bottom end of the flood control component 52; the distal end of the windproof cloth 82 of the other lifting mechanism is detachably connected to the rear edge of the bottom end of the flood control component 52. In this embodiment, the windproof cloth 82 is detachably connected to the flood control component 52 using multiple sets of snap fasteners. The snap fasteners located on the same side are evenly spaced along the length of the flood control component 52. When it is necessary to lower the flood control component 52 from the ground back to the storage box 6, the windproof cloth 82 can be connected to the flood control component 52, and then the lifting mechanism can be activated to retrieve the flood control component 52.

[0070] Reference Figure 8 and Figure 13The storage tank 6 is further equipped with a dewatering plate 62 on the lower side of the two take-up rollers 81 for squeezing the flood control component 52. The dewatering plate 62 is arranged horizontally, and channels for the windproof cloth 82 to pass through are formed between the dewatering plate 62 and the front and rear inner walls of the storage tank 6. When the flood control component 52 is recycled into the storage tank 6, the dewatering plate 62 can squeeze the flood control component 52, thereby discharging the water inside the flood control component 52 through the second connector 5213.

[0071] Reference Figure 9 and Figure 13 The storage box 6 has a placement opening 63 on its top, and a placement end cap 64 that closes the placement opening 63. The placement end cap 64 is hinged and rotated on the storage box 6. The placement end cap 64 allows the user to place the cam column 54 and the support column 55 on the upper part of the storage box 6.

[0072] The flood control implementation principle of an underground garage entrance structure in this application embodiment is as follows: 1. The storage box 6 is slid from the first station to the second station using the drive component; 2. Using a lifting mechanism, the flood control component 52 inside the storage box 6 is lowered from inside the storage box 6 to the top surface of the entrance channel 1; 3. Place the bottom of the flood control component 52 against the flood control base 53, and insert the cam column 54 into the cam insertion hole 5215 of the flood control outer sleeve 521 and the support hole 5221 of the flood control frame plate 522, and rotate the cam column 54 so that the first flood control frame plate 522 and the second flood control frame plate 522 are engaged in the sealing groove 511 of the flood control slide 51; 4. Insert the support column 55 into the support channel 5216 of the flood control outer jacket 521 and the snap ring 5229 of the flood control frame plate 522, and rotate the support column 55 so that the snap protrusion 552 on the support column 55 can snap into the snap groove 52291 of the flood control ring, so that the flood control component 52 can be supported. 5. Water is pumped into the flood control component 52 through the first connector 5211, so that the flood control component 52 can expand under the action of water, thus producing a flood control effect; 6. After the flood control component 52 is used, the lifting mechanism lifts the flood control component 52 into the storage box, and the drive component moves the storage box 6 to the first working position, thereby retracting the flood control component 52.

[0073] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
