Description

Technical Field

[0001] The utility model relates to the technical field of bridge expansion joint waterproof equipment, in particular to a waterproof device used for an ultra-wide bridge expansion joint. Background Art

[0002] Bridge expansion joints refer to gaps or connections set in bridge structures to adapt to expansion and contraction deformation caused by factors such as temperature changes and earthquakes. Expansion joints in bridge structures can also reduce structural stress concentration caused by temperature changes, thereby extending the service life of the bridge. At present, the waterproofing devices of some ultra-wide bridge expansion joints usually install silicone sealant strips between the metal parts of the bridge expansion joints to prevent moisture from penetrating into the expansion joints. However, the silicone sealant strips installed between the metal parts in the bridge gaps will age and lose their original elasticity and sealing properties after long-term use and exposure to the external environment, resulting in cracks or damage, which will allow moisture to penetrate. If the infiltrated water is not discovered in time and the sealant strips are not replaced, the metal parts inside the bridge structure will be exposed to a humid environment and corroded, thereby reducing the bearing capacity and service life of the bridge.

[0026] Example

[0027] like Figure 1-5 As shown, the utility model proposes a waterproof device for expansion joints of super-wide bridges, comprising a pair of bridge bodies 1 and an expansion joint 3 arranged between the bridge bodies 1, and the opposite ends of the bridge bodies 1 are located inside the expansion joint 3 and fixedly connected with a support bar 11 for supporting a water receiving trough 4, and the function of the support bar 11 is to limit the installation depth of the water receiving trough 4 inside the expansion joint 3. A waterproof mechanism is installed inside the expansion joint 3, and also includes: a water collecting mechanism for collecting water leaking from the waterproof mechanism; and an alarm mechanism installed in the water collecting mechanism for quickly reminding maintenance personnel that the waterproof mechanism on the expansion joint 3 is leaking.

[0028] Furthermore, the water collecting mechanism includes a water receiving trough 4 installed in the expansion joint 3 and arranged linearly and located directly below the waterproof mechanism. The inner bottom wall of the inner center of the water receiving trough 4 is the lowest position, and its function is to make water flow to the lowest position. The alarm mechanism includes a mounting groove 45 opened on the inner bottom wall of the water receiving trough 4, and a water immersion sensor 46 is fixedly connected to the inside of the mounting groove 45. The water immersion sensor 46 is a sensor specially used to detect water level or water immersion. When the water level reaches or exceeds the position of the sensor, the sensor will trigger the corresponding signal output, thereby starting the relevant equipment or system. One of the water receiving troughs 4 is located at the end of the expansion joint 3 and is fixedly connected to an L-shaped support rod 42. The end of the L-shaped support rod 42 close to the water receiving trough 4 is fixedly connected to a mounting member 41. The function of the mounting member 41 is to enable the L-shaped support rod 42 to be quickly disassembled and assembled on the water receiving trough 4. The mounting member 41 is provided with a plurality of bolts distributed in a circumferential array and used to fix the L-shaped support rod 42 on the water receiving trough 4. The top end of the L-shaped support rod 42 is fixedly connected with an alarm 43 electrically connected to the water immersion sensor 46. The alarm 43 is a device for sending an alarm signal to remind or alert people to an emergency or dangerous situation. The interior of the water receiving trough 4 is provided with a mounting mechanism for quickly disassembling and assembling the water receiving trough 4 in the expansion joint 3.

[0029] Among them, the installation mechanism includes a plurality of pairs of telescopic holes 44 opened in the water receiving trough 4, and each pair of telescopic holes 44 is movably connected with an elliptical stop block 54 inside. The side of the elliptical stop block 54 contacting the bridge body 1 is provided with a plurality of anti-slip protrusions 55, and the opposite surface of the elliptical stop block 54 is fixedly connected with a threaded rod 5, and the opposite end of the threaded rod 5 is spirally sleeved with a threaded sleeve rod 51. The installation mechanism also includes a rotating rod 52 fixedly sleeved on the threaded sleeve rod 51, and the rotating rod 52 is provided with a plurality of sockets 53 distributed in a circular array.

[0030] Furthermore, the waterproof mechanism includes a metal connector 2 arranged on the opposite end of the bridge body 1. The metal connector 2 refers to a metal component used at the expansion joint of the bridge. Its main function is to connect, seal and bear load at the expansion joint of the bridge. The opposite ends of the metal connector 2 are provided with a C-shaped embedding groove 22. The interior of the C-shaped embedding groove 22 is inlaid with an installation ear strap 23. The function of the installation ear strap 23 is to be inserted into the C-shaped embedding groove, so that the waterproof device is installed. The opposite end of the installation ear strap 23 is provided with a telescopic body 21 for preventing water from leaking into the expansion joint 3. The material of the telescopic body 21 is rubber or silicone.

[0031] In this embodiment, when a waterproof device is required for an ultra-wide bridge expansion joint, such as Figure 1 As shown, multiple water receiving troughs 4 are sequentially placed in the expansion joints 3 on the opposite ends of the bridge body 1. The water receiving troughs 4 are stably placed inside the expansion joints 3 through the support of the support bars 11 inside the expansion joints 3, and the ends of the water receiving troughs 4 are tightly attached. Then the end of the tool is inserted into the socket 53 on the rotating rod 52 and the tool is rotated. The tool drives the rotating rod 52 and the threaded sleeve 51 to rotate in turn. Since the threaded sleeve 51 is spirally connected to the threaded rod 5, the end of the threaded rod 5 away from the threaded sleeve 51 drives the elliptical block 54 to slide along the expansion hole 44 on the water receiving trough 4. Then the elliptical block 54 drives the multiple anti-slip protrusions 55 thereon to firmly press against the bridge body 1, so that the water receiving trough 4 can be fixedly installed inside the expansion joint 3.

[0032] When the waterproof mechanism installed on the expansion joint 3 is used for a long time and exposed to the external environment, the expansion body 21 ages and loses its original elasticity and sealing performance, thereby generating cracks or damage, so that water can penetrate. Then the water that penetrates through the expansion body 21 will drip into the inside of the water receiving tank 4 by gravity, and flow to the installation groove 45 on the inner bottom wall of the water receiving tank 4, and the water immersion sensor 46 in the installation groove 45 will be activated when it contacts the water, and the alarm 43 on the L-shaped support rod 42 will be activated through the controller. After the alarm 43 is activated, a sound and light source for prompting people will be generated, so that water leakage of the waterproof device of the ultra-wide bridge expansion joint can be discovered in time.

[0033] The preferred embodiments of the utility model of the above utility model are only used to help explain the utility model. The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
