Description

Technical Field

[0001] The present application relates to the technical field of building waterproofing, and in particular to a waterproofing device for a building at an entrance above a subway line. Background Art

[0002] With the rapid development of urban subway transportation, subway entrances are key nodes for passengers to enter and exit the subway system, and the reliability and functionality of their building structures have attracted much attention. Since subway entrances are usually located above the ground and directly exposed to the natural environment, they are frequently attacked by rain. Traditional entrance building waterproofing designs often have many defects and are difficult to meet the stringent requirements of subway operations for waterproofing effects.

[0003] On the one hand, some existing entrance canopies have simple structures and insufficient stability of the support system. In severe weather conditions such as strong winds and heavy rains, they are prone to shaking or even displacement, which not only affects the safety of passengers entering and exiting, but may also cause a large amount of rainwater to seep in from the connection gap between the canopy and the support structure, causing damage to the facilities and ground in the station. For example, some simple canopies only use a single column support and lack effective horizontal and vertical connection reinforcement. After long-term use, the column foundation becomes loose, the canopy tilts, and the waterproof function is greatly reduced.

[0004] On the other hand, the waterproof structure of the traditional canopy is not sophisticated enough. The joints between the water retaining plates are not tightly sealed, and rainwater can easily penetrate into the entrance through the gaps. Moreover, the drainage design of the ceiling is unreasonable, and the accumulated water cannot be discharged in time, further increasing the risk of rainwater leakage. Furthermore, most of the existing canopies do not take into account the compatibility with the subway entrance passage and the convenience of subsequent maintenance. Once a waterproofing problem occurs, maintenance is difficult and costly, and it may even be necessary to close the entrance for a long time, affecting the normal operation of the subway.

[0005] In summary, a new type of waterproofing device for subway entrance buildings is urgently needed to solve the above problems, ensure that the subway entrance can maintain good waterproof performance under various weather conditions, and ensure the safe and efficient operation of the subway system.

DETAILED DESCRIPTION

[0020] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of the present invention is not limited to the following embodiments, and any form of modification and / or change made to the present invention will fall within the protection scope of the present invention.

[0021] Embodiment 1: like Figure 1 , 2 As shown, the present invention discloses a technical solution, a waterproof device for a building at an entrance above a subway line, comprising a first supporting structure 1, a second supporting structure 2, a first connecting structure 3, a second connecting structure 4, a reinforcing structure 5 and a ceiling structure 6; the first supporting structure 1 and the second supporting structure 2 play a role in supporting the ceiling structure 6, the first connecting structure 3 and the second connecting structure 4 play a role in enhancing the structural strength of the first supporting structure 1, and the reinforcing structure 5 can improve the supporting stability of the ceiling structure 6, thereby ensuring the long-term stable operation of the entire waterproof device.

[0022] Specifically, two first supporting structures 1 are provided front and rear along the length direction of the subway entrance passage, which are used to support the entire waterproof device. Each first supporting structure 1 includes a first supporting crossbeam 11 and a first supporting vertical beam 12 installed on the left and right ends of the lower surface of the first supporting crossbeam 11. The first supporting vertical beam 12 includes an upper supporting tube 121 and a lower supporting tube 122 inserted into the lower end of the upper supporting tube 121. The first supporting crossbeam 11 and the upper supporting tube 121 at the upper end of the first supporting vertical beam 12 are fixedly connected by bolts, and a reinforcement block 15 is installed between the connecting parts. A telescopic mechanism 13 for adjusting the position of the upper supporting tube 121 is provided between the upper supporting tube 121 and the lower supporting tube 122, so that the height of the entire waterproof device can be adjusted, and a walking mechanism 14 is provided at the lower end of the lower supporting tube 122 to facilitate the movement and installation of the waterproof device.

[0023] The above-mentioned reinforcement block 15 is made of rubber, which has the effect of buffering and shock absorption on the one hand. When the waterproof device above the subway entrance is impacted by external force, such as the shaking force transmitted by the ceiling structure 6 under the action of strong wind, or the accidental collision that may occur during the installation and maintenance process, the reinforcement block 15 made of rubber can effectively absorb these impact forces. Compared with traditional rigid reinforcement materials, rubber can better cope with dynamic external force changes. When the walking mechanism 14 vibrates during movement, or the ceiling structure 6 vibrates slightly under the action of wind and rain, the rubber reinforcement block 15 can play a role in isolating vibration. The elasticity of rubber can prevent the vibration from being directly transmitted between the first supporting crossbeam 11 and the first supporting vertical beam 12, avoiding the vibration from propagating and amplifying in the entire structure, which helps to maintain the stability of the structure, reduce the fatigue damage of components caused by long-term vibration, reduce the looseness of the connection parts caused by vibration, and extend its service life; on the other hand, the rubber material has a certain softness and plasticity, which can better fill the tiny gap that may exist between the first supporting crossbeam 11 and the first supporting vertical beam 12, so that it always maintains a tight fit.

[0024] Specifically, the first connection structure 3 is composed of a first support longitudinal beam 31 connected between two first support beams 11. The first support longitudinal beams 31 are provided with two left and right ones, respectively corresponding to the two ends of the first support beam 11. A first connection flange 111 is welded on one side where the first support beam 11 is connected to the first support longitudinal beam 31, and a reliable connection between the first support beam 12 and the first support longitudinal beam 31 is achieved through the first connection flange 111.

[0025] Specifically, the second connection structure 4 includes a second support beam 41 connected between two first support longitudinal beams 31 , and a plurality of second support beams 41 are evenly arranged along the length direction of the first support longitudinal beams 31 to further improve the stability of the entire waterproof device.

[0026] Specifically, the cross-section of the ceiling structure 6 is an arc structure, including a top plate mechanism 61 and a side plate mechanism 62 connected to the left and right sides of the top plate mechanism 61. The top plate mechanism 61 and the side plate mechanism 62 both include a support frame group 63 and a water retaining plate 64 installed on the support frame group 63. A sealing layer is provided between adjacent water retaining plates 64 to ensure a waterproof effect. The lower end surface of the side plate mechanism 62 is higher than the lower end surface of the walking mechanism 14, which prevents rainwater from seeping in from the bottom on the one hand, and ensures the feasibility of the walking mechanism 14 on the other hand.

[0027] Specifically, the second supporting structure 2 includes a second supporting longitudinal beam 21 fixedly mounted on the upper surface of the first supporting longitudinal beam 31 . Two second supporting longitudinal beams 21 are provided, and the upper ends of the second supporting longitudinal beams 21 are fixedly connected to the top plate mechanism 61 for supporting the top plate mechanism 61 .

[0028] Specifically, the reinforcing structure 5 is composed of a first reinforcing component 51 and a second reinforcing component 52. The first reinforcing component 51 is installed between the top plate mechanism 61 and the side plate mechanism 62, and the second reinforcing component 52 is installed between the side plate mechanism 62 and the first supporting longitudinal beam 31, so as to further improve the structural strength of the entire waterproof device.

[0029] Embodiment 2: like Figure 3 , 4As shown, the present invention discloses another technical solution, a waterproof device for a building at an entrance above a subway line, which is different from the embodiment 1 in that the telescopic mechanism 13 is composed of a telescopic assembly 131 and a support assembly 132, the fixed end of the telescopic assembly 131 is fixedly connected to the side wall of the upper support tube 121 by bolts, the telescopic end of the telescopic assembly 131 is fixedly connected to the side wall of the lower support tube 122 by bolts, the support assembly 132 is composed of an upper mounting plate 1321, a lower limit plate 1322 and a support screw 1323, the support screw 1323 is threadedly connected to the upper mounting plate 1321, the upper mounting plate 1321 and the lower limit plate 1322 are respectively welded or bolted to the side wall of the upper support tube 121 and the side wall of the lower support tube 122, and the lower end of the support screw 1323 abuts against the upper surface of the lower limit plate 1322; The telescopic components 131 and the supporting components 132 are symmetrically provided with two groups, and the telescopic components 131 and the supporting components 132 are staggeredly installed around the first supporting vertical beam 12; when the height needs to be adjusted, the telescopic component 131 is started to change the position of the upper supporting tube 121. When the adjustment is completed, the supporting screw 1323 is rotated by a tool so that its bottom contacts the upper surface of the lower limit plate 1322, which has a good supporting effect; the telescopic mechanism 13 can not only realize the flexible adjustment of the height of the first supporting vertical beam 12 to adapt to the height requirements of different terrains, but also provide stable support through the supporting component 132 after being adjusted into place, prevent the upper supporting tube 121 from sliding down, and ensure the reliability of the supporting structure; the above-mentioned telescopic component 131 can adopt a push rod motor or a cylinder or a hydraulic cylinder, and its driving method is not within the protection scope of this application and will not be repeated here.

[0030] Specifically, the walking mechanism 14 is composed of a mounting box 141 and walking wheels 142. The upper surface of the mounting box 141 is fixedly connected to the lower end of the lower support tube 122 by bolts. The bottom of the mounting box 141 is open and the interior is hollow. There are at least two walking wheels 142, which are rotatably connected to the mounting box 141 through a rotating shaft. The lower end surface of the walking wheel 142 should be higher than the lower end surface of the mounting box 141. The walking mechanism 14 facilitates the movement of the entire waterproof device during installation, maintenance or fine-tuning of the position, reducing the cost of manpower handling. At the same time, the setting of the walking wheel 142 avoids direct friction with the ground, thereby extending its service life. When used specifically, corresponding slide rails can be set on both sides of the subway line, and the walking wheel 142 can roll on the slide rails. The structure of the walking wheel 142 can refer to the subway wheel, and its specific structure will not be repeated here.

[0033] Embodiment 5: like Figure 5 , 6 As shown, the present invention discloses another technical solution, a waterproof device for a building at an entrance above a subway line, which is different from Example 1 in that the above-mentioned first reinforcement component 51 and the second reinforcement component 52 both include a plurality of telescopic rods 53 distributed along the length direction of the subway entrance passage, and the second reinforcement component 52 is provided with two groups, one of which is connected between the side of the first supporting longitudinal beam 31 and the side panel mechanism 62, and the other is connected between the bottom of the first supporting longitudinal beam 31 and the side panel mechanism 62. The telescopic rod 51 can adopt a damper strut, which can be adaptively adjusted according to the stress condition of the ceiling, and provide support force for the ceiling in real time, especially in extreme weather such as strong winds, effectively disperse stress, prevent deformation and damage of the ceiling, and ensure the overall structural strength of the waterproof device.

[0034] Embodiment 6: like Figure 7 , 8As shown, the present invention discloses another technical solution, a waterproof device for a building at an entrance above a subway line, which is different from Example 1 in that the above-mentioned support frame group 63 includes a first support frame 631 and a second support frame 632, and the water retaining plates 64 are all installed on the first support frame 631. The top plate mechanism 61 adopts the first support frame 631, the side plate mechanism 62 is close to the first support frame 631 at the position of the top plate mechanism 61, and the bottom of the side plate mechanism 62 adopts the second support frame 632. Adaptive support frames are used at different positions, which can meet the different force requirements of the ceiling and the side plates. It can also optimize material usage and reduce costs. The first support frame 631 provides stable support for the water retaining plate 64. The second support frame 632 plays a role of reinforcement and connection at the bottom of the side plate, and can also provide stable support for the water retaining plate 64. In this embodiment, the top plate mechanism 61 adopts three rows of first support frames 631, each row is provided with seven groups, and the side plate mechanism 62 is provided with two rows of first support frames 631 and one row of second support frames 632, each row is also provided with seven groups. Adjacent first support frames 631 and between the first support frame 631 and the second support frame 632 are fixedly connected by bolts.

[0035] Specifically, Fig. 9 , 10 As shown, the first support frame 631 includes a first frame body 6311 which is hollow inside and opened at the upper and lower parts, and a plurality of V-shaped support plates 633 are uniformly welded inside the first frame body 6311 along its length direction, and a water retaining plate 64 is sealed and connected to the upper opening of each first support frame 631.

The V-shaped support plate 633 increases the bending resistance of the support frame group 63, so that the water retaining plate 64 can be installed more firmly, can effectively resist the impact of rain water, and ensure the stability of the entire side panel mechanism.

[0036] Specifically, the sealing layer protrudes from the upper surface of the water retaining plate 64, and the upper end of the sealing layer is a raised semicircular arc. Silicone sealant is used to install the water retaining plate 64 on the first supporting frame 631 and fill the gap between adjacent water retaining plates 64. The silicone sealant can solidify in a humid environment to form a tough sealing layer, which has good resistance to rainwater, chemical components in dust, etc. that the subway entrance may be exposed to. It has high bonding strength and can firmly bond the water retaining plate 64 and the first supporting frame 631 together, while being able to adapt to a certain degree of displacement and deformation. Moreover, the protruding sealing layer can effectively prevent rainwater from penetrating from the gaps between adjacent water retaining plates 64. Even when a large amount of rainwater accumulates or strong wind drives rainwater to impact, it can ensure that rainwater slides down the surface of the water retaining plate to avoid water ingress into the interior of the entrance, thereby improving waterproof reliability. In addition, in order to ensure its good water retaining effect, EPDM rubber waterproof membrane can be laid on the surface of the water retaining plate 64 to achieve a multi-layer waterproof effect.

[0037] The waterproof device for subway line entrance building of the present invention effectively solves the waterproof problem of existing subway entrances through innovative structural design, has broad application prospects, and can be widely used in various types of urban subway entrance construction and renovation projects.
