Description

Technical Field

[0001] The utility model relates to the technical field of civil engineering, in particular to a waterproof structure of a civil engineering expansion joint. Background Art

[0002] A building expansion joint, also known as a building expansion joint, is a structural joint installed at appropriate locations along the construction joint of a building or structure to prevent cracks or damage to the structure due to temperature fluctuations (thermal expansion and contraction). An expansion joint divides building components above the foundation, such as walls, floor slabs, and roofs (except wooden roofs), into two independent sections, allowing the building or structure to expand and contract horizontally along its length. Existing expansion joints are mostly exposed directly on the structure. Due to long-term exposure to air, dust, debris, and acid rain, they gradually deteriorate, hindering their maintenance. Furthermore, water easily seeps through expansion joints, and accumulated water corrodes steel plates and other metal building components, shortening the service life of the expansion joint structure. Therefore, it is necessary to develop a waterproof expansion joint structure for civil engineering.

[0003] In response to the above problems, the patent number CN217557243U discloses a waterproof structure for expansion joints in civil engineering, including a wall and a waterstop, with an expansion joint remaining between the two walls, a second groove recessed in the top wall of the two walls near one side, a baffle provided on the upper surface of the two second grooves located directly above the expansion joint, and a first groove recessed in the upper surface of the wall near the second groove. In this utility model, when the spacing of the expansion joint changes due to thermal expansion and contraction, the baffle moves in the corresponding upper and lower positioning grooves through the lower positioning slider and the upper positioning slider, thereby adjusting the position of the baffle in the expansion joint, and the connecting blocks on both sides of the waterstop also have a range of movement in the installation cavity, thereby avoiding tearing damage to the waterstop; the existing expansion joint is covered to prevent rainwater, dust, etc. from entering the expansion joint, thereby protecting the expansion joint and improving the service life of the expansion joint structure.

[0004] However, the civil engineering expansion joint waterproof structure still has the following problems when in use: 1. The civil engineering expansion joint waterproof structure can only prevent rainwater from seeping into the expansion joint, but cannot collect rainwater for reuse; 2. If the civil engineering expansion joint waterproof structure encounters excessive thermal expansion or contraction of the wall, it is easy to cause structural damage, thereby affecting the waterproof effect. Utility Model Content

[0005] In view of the above-mentioned problems, the present invention aims to provide a civil engineering expansion joint waterproof structure, which at least solves the problem that the civil engineering expansion joint waterproof structure in the prior art cannot collect and reuse rainwater.

[0006] The main ideas of the technical solution adopted by this utility model are:

[0007] A waterproof structure for expansion joints in civil engineering is designed, including: a waterproof component and a water storage component. The waterproof component includes a connecting plate fixedly connected to the wall, and a movable plate slidably connected to the bottom of the connecting plate, and the position of the movable plate in the expansion joint can be adjusted; the water storage component is arranged above the waterproof component, and rainwater is collected for recycling and reuse. The water storage component is divided into a first water storage component and a second water storage component. When the rainfall is small, the second water storage component operates, and when the rainfall is heavy, the first water storage component and the second water storage component operate simultaneously to store water.

[0008] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention to solve the technical problem is:

[0009] Design a waterproof structure for expansion joints in civil engineering, the waterproof structure being located between two walls and comprising a first step arranged at the top of the wall, and a second step being arranged below the first step;

[0010] A waterproof component is provided between the two first steps and the second step;

[0011] The top of the waterproof component is detachably connected to a water storage component.

[0012] Furthermore, the waterproof assembly includes: a movable plate and two connecting plates;

[0013] The two connecting plates are respectively arranged on the two first steps, and the tops of the connecting plates are flush with the tops of the walls;

[0014] The movable plate is slidably arranged between the two second steps and is slidably connected to the bottoms of the two connecting plates.

[0015] Further, the water storage assembly includes a U-shaped block mounted on top of the movable plate;

[0016] Extension plates are provided on both sides above the U-shaped block, and notches are provided in the extension plates;

[0017] The slot is connected to provide a first water storage component and a second water storage component. The first water storage component is located inside the U-shaped block, and the second water storage component is located outside the U-shaped block.

[0018] Furthermore, the first water storage assembly includes: an opening and a chamber;

[0019] A chamber for storing water is provided in the U-shaped block, an opening is provided between the chamber and the notch, and a switch assembly for opening the opening is provided on the outer side wall of the U-shaped block.

[0020] Furthermore, the switch assembly includes: a baffle, a buoyancy ball and two traction lines;

[0021] The baffle is slidably connected to the opening;

[0022] The buoyancy ball is arranged above the baffle and is respectively connected to the U-shaped block and the baffle through two traction lines.

[0023] Furthermore, the second water storage assembly includes: a chain, a T-shaped piece and a water storage bucket;

[0024] The top of the chain is connected to the T-piece, and the bottom is connected to the water storage bucket;

[0025] A first through hole is provided at the bottom of the slot, and the T-shaped piece passes through the first through hole and is clamped.

[0026] Furthermore, limit members are provided at both ends below the second step, and L-shaped plates are provided at both ends of the movable plate;

[0027] The L-shaped plate is located between the two limiting members.

[0028] The beneficial effects of the present invention are as follows: Compared with the prior art, the improvements of the present invention are:

[0029] The utility model blocks rainwater by arranging a waterproof component, thereby preventing rainwater from penetrating through the expansion joint. The waterproof component can not only effectively prevent moisture from damaging the building structure, thereby extending the service life of the building, but also enable the expansion joint to maintain good waterproof performance when deformed, thereby maintaining the overall stability of the building.

[0030] The utility model collects and reuses rainwater by arranging a water storage component, while preventing rainwater from seeping into the expansion joint through the waterproof component. Since the collected rainwater can be used as a free water resource, it can be used for various non-drinking water needs such as irrigation, flushing toilets, road cleaning, etc. after proper treatment, thereby reducing the consumption of tap water and achieving the purpose of water saving.

[0031] The utility model divides the water storage component into a first water storage component and a second water storage component, so that the second water storage component stores water during light rain, and the first water storage component and the second water storage component store water at the same time during heavy rain, thereby avoiding excessive rainfall resulting in poor water storage effect of the second water storage component.

[0032] The utility model provides a limiter and an L-shaped plate. When the wall expands or contracts excessively due to heat or cold, the relative position between the wall and the movable plate will change, thereby changing the relative position between the L-shaped plate and the limiter. When the L-shaped plate contacts the limiter, the thermal expansion or contraction of the wall reaches the limit of normal value. The limiter sends a signal to remind maintenance personnel to repair and replace the waterproof component as soon as possible, avoiding the situation where the thermal expansion or contraction of the wall is too large and the waterproof effect of the waterproof component fails.

[0043] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments, rather than all the embodiments.

[0044] In the description of the present invention, it should be understood that the terms "front", "back", "left", "right", "up", "down", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention. Example 1

[0045] like Figure 1-8 As shown, the present application discloses a civil engineering expansion joint waterproof structure, which is located between two walls 10. An expansion joint is provided between the two walls 10 to prevent cracks or damage to the building components due to climate temperature changes (thermal expansion and contraction). The waterproof structure includes a first step 11 provided at the top of the wall on the side adjacent to the expansion joint, with a second step 12 provided below the first step 11. A waterproof assembly is provided between the first and second steps 11, 12. The waterproof assembly can block rainwater and prevent it from seeping into the expansion joint. The waterproof assembly not only effectively prevents moisture from damaging the building structure, thereby extending the building's service life, but also ensures that the expansion joint maintains good waterproof performance during deformation, thereby maintaining the overall stability of the building. A water storage assembly is detachably connected to the top of the waterproof assembly. The water storage assembly can collect rainwater. While preventing rainwater from seeping into the expansion joint through the waterproof assembly, the rainwater is collected and reused. Since the collected rainwater can serve as a free water resource, after proper treatment, it can be used for various non-potable water needs such as irrigation, toilet flushing, and road cleaning, thereby reducing tap water consumption and achieving the goal of water conservation. In addition, rainwater carries some pollutants from the atmosphere during its fall. If directly discharged into the urban drainage system, it may cause certain pollution to the environment. Therefore, collecting rainwater through the water storage assembly can reduce environmental pollution to a certain extent.

[0046] Furthermore, if Figure 3 and Figure 4As shown, the waterproof assembly includes: a movable plate 20 and two connecting plates 30; the two connecting plates 30 are respectively arranged on the first steps 11 of the two walls 10, and the top of the connecting plate 30 is flush with the top of the wall 10; a plurality of threaded holes 32 are provided on the connecting plate 30, and the connecting plate 30 is fixed to the first step 11 of the wall 10 by the cooperation of the bolts 70 and the threaded holes 32; two second grooves 31 are provided at the bottom of the connecting plate 30, and a first groove 13 is provided on the second step 12 of the wall 10; four The first protrusions 21, the four first protrusions 21 are respectively slidably connected to the second grooves 31 at the bottom of the two connecting plates 30; four second protrusions 22 are provided at the bottom of the movable plate 20, and the four second protrusions 22 are respectively slidably connected to the first grooves 13 of the two walls 10; when the gap spacing of the expansion joint changes due to thermal expansion and contraction of the wall 10, the movable plate 20 moves in the corresponding second grooves 31 and first grooves 13 through the first protrusions 21 and the second protrusions 22, thereby adjusting the position of the movable plate 20 in the expansion joint.

[0047] Furthermore, the water storage assembly includes a U-shaped block 40 mounted on the top of the movable plate 20, a third protrusion 23 is provided on the top of the movable plate 20, and a clamping groove matching the third protrusion 23 is provided at the bottom of the U-shaped block 40. The third protrusion 23 is clamped with the clamping groove to facilitate the installation of the water storage assembly. When installing the civil engineering expansion joint waterproof structure, the movable plate 20 is installed first, then the connecting plate 30, and finally the water storage assembly is installed through the third protrusion 23, which reduces the difficulty of installation; the two sides above the U-shaped block 40 An extension plate 41 is provided, and a notch 411 is provided in the extension plate 41; the bottom of the U-shaped block 40 abuts the top of the connecting plate 30; an extension plate 41 is provided on both sides above the U-shaped block 40, and a notch 411 is provided in the extension plate 41. The extension plate 41 is connected to both sides of the U-shaped block 40 to facilitate the collection of rainwater to one end of the notch 411; the notch 411 is connected to the first water storage component and the second water storage component, the first water storage component is located inside the U-shaped block 40, and the second water storage component is located outside the U-shaped block 40.

[0048] Furthermore, if Figure 5 and Figure 8As shown, the first water storage component includes: an opening 42 and a chamber 45; a chamber 45 is provided in the U-shaped block 40, an opening 42 is provided between the chamber 45 and the slot 411, and a switch component for opening the opening 42 is provided on the outer wall of the U-shaped block 40; when rainwater falls from above the expansion joint, it slides down from the top of the U-shaped block 40 and flows into the slot 411. When the rain is heavy, water accumulates in the slot 411 and flows into the chamber 45 through the opening 42 for storage; a second through hole 44 is also provided on the U-shaped block 40, and a water pump is provided between the chamber 45 and the second through hole 44. The water stored in the chamber 45 can be discharged from the second through hole 44 through the water pump and used. When the water is not discharged, the second through hole 44 is covered by a sealing cover to prevent the stored water from overflowing.

[0049] Furthermore, if Figure 2 As shown, the switch assembly includes: a baffle 60, a buoyancy ball 61 and two traction lines 62; the baffle 60 is slidably connected to the opening 42; the buoyancy ball 61 is arranged above the baffle 60, and a fixed block 43 is arranged above the buoyancy ball 61, the fixed block 43 is fixedly connected to the U-shaped block 40, the bottom of the fixed block 43 is connected to a traction line 62, and the other end of the traction line 62 is connected to the buoyancy ball 61; the bottom of the buoyancy ball 61 is also connected to a traction line 62, and the other end of the traction line 62 is connected to the top of the baffle 60; when it rains heavily, water accumulates in the slot 411, and the accumulated water causes the buoyancy ball 61 to generate buoyancy, and the buoyancy ball 61 floats upward while pulling the traction line 62, and the traction line 62 generates an upward pulling force on the baffle 60, so the baffle 60 slides upward and leaks the opening 42, so that the accumulated water flows from the opening 42 into the chamber 45 for storage.

[0050] Furthermore, if Figure 6 As shown, the second water storage assembly includes: a chain 50, a T-shaped piece 51 and a water storage bucket 52; the top of the chain 50 is connected to the T-shaped piece 51, and the bottom is connected to the water storage bucket 52; a first through hole 412 is provided at the bottom of the notch 411, and the first through hole 412 is provided on the lower side of the extension plate 41, the T-shaped piece 51 passes through the first through hole 412, and the rod at the top of the T-shaped piece 51 is larger than the diameter of the first through hole 412, and the rod at the top of the T-shaped piece 51 is clamped into the first through hole 412, thereby achieving the fixation of the chain 50; in the rain When the water level is low, rainwater falls from above the expansion joint and slides down from the top of the U-shaped block 40 and flows into the slot 411. Since the first through hole 412 is arranged on the lower side of the extension plate 41, the rainwater flows further toward the first through hole 412. Finally, the rainwater is retained by the first through hole 412 and flows into the water storage barrel 52 along the chain 50. The second water storage component is provided to store water when the rainfall is low. The chain 50 structure not only makes it beautiful, but also avoids the problem of using pipe drainage, which makes the inside of the pipe difficult to clean. Example 2

[0051] On the basis of Example 1, in order to prevent the wall 10 from expanding and contracting to a large extent and causing the waterproof effect of the waterproof component to fail, further, limit members 80 are provided at both ends below the second step 12, and L-shaped plates 24 are provided at both ends of the movable plate 20. One end of the L-shaped plate 24 is fixedly connected to the movable plate 20, and the other end extends outward from the wall 10. When the wall 10 expands and contracts excessively, the relative position between the wall 10 and the movable plate 20 will change, thereby changing the relative position between the L-shaped plate 24 and the limit member 80. When the L-shaped plate 24 contacts the limit member 80, it indicates that the thermal expansion and contraction of the wall 10 has reached the limit of normal value, and the wall 10 and the waterproof component need to be inspected and repaired. Specifically, the limit member 80 can be a sensor or other device that can generate an alarm when in contact.

[0052] The specific principle of a civil engineering expansion joint waterproof structure provided in the utility model during use is:

[0053] Waterproofing: The movable plate 20 and two connecting plates 30 provided on the expansion joint block rainwater from entering the expansion joint. When the gap spacing of the expansion joint changes due to thermal expansion and contraction of the wall 10, the movable plate 20 moves within the corresponding second groove 31 and first groove 13 via the first protrusion 21 and the second protrusion 22, thereby adjusting the position of the movable plate 20 in the expansion joint.

[0054] Water storage: When the rainfall is light, rainwater falls from above the expansion joint and slides down from the top of the U-shaped block 40 and flows into the notch 411. Since the first through hole 412 is provided on the lower side of the extension plate 41, the rainwater flows further toward the first through hole 412. Finally, the rainwater is retained by the first through hole 412 and flows along the chain 50 into the water storage barrel 52, thus achieving water storage.

[0055] When it rains heavily, water accumulates in the slot 411. The accumulated water generates buoyancy in the buoyancy ball 61. The buoyancy ball 61 floats upward while pulling the traction line 62. The traction line 62 generates an upward pulling force on the baffle 60. Therefore, the baffle 60 slides upward and leaks the opening 42, allowing the accumulated water to flow from the opening 42 into the chamber 45 for storage.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
