Description

Technical Field

[0001] This application relates to the field of building expansion joints, and in particular to a high-durability expansion joint protection structure. Background Technology

[0002] To solve the problem of water leakage at building expansion joints, steel plate expansion joints are usually used. However, after long-term use, foreign objects will inevitably fall into the expansion joint, causing blockage of the drainage ditch below, which will lead to more serious leakage and corrosion of the expansion joint, posing a threat to the safety of the building.

[0003] Regarding the aforementioned technologies, the inventors believe that after prolonged use, steel plate expansion joints may experience leakage and corrosion due to blockage of the drainage ditch below caused by falling foreign objects, posing a potential safety hazard to the building. Utility Model Content

[0004] The purpose of this application is to provide a high-durability expansion joint protection structure to improve the problem of leakage and corrosion of stainless steel expansion joints caused by foreign objects falling into the drain and causing blockage of the drain due to long-term use, which poses a hidden danger to the use of the building.

[0005] The high-durability expansion joint protection structure provided in this application adopts the following technical solution:

[0006] A high-durability expansion joint protection structure includes two concrete joints and an expansion joint located between the two concrete joints. Each concrete joint has a structural retaining wall extending from the expansion joint. A drainage ditch is provided on the upper surface of each concrete joint, and the drainage ditch is located between the concrete joint and the structural retaining wall. The sidewalls of the two concrete joints and the upper surfaces of the two structural retaining walls together form an installation groove, and a cover plate is provided on the inner sidewall of the installation groove.

[0007] By adopting the above technical solution, the cover plate on the concrete joint will cover the expansion joint and prevent water from entering the expansion joint. The structural retaining walls on both sides of the expansion joint can effectively block water from entering the expansion joint, and the drainage ditch can collect and discharge the water that enters the expansion joint.

[0008] Optionally, a fall-prevention steel mesh is provided between the two concrete joints, and the two sides of the fall-prevention steel mesh are connected to the inner wall of the expansion joint.

[0009] By adopting the above technical solution, anti-fall steel mesh is installed between concrete joints to prevent falling objects from entering the drainage ditch below and causing blockage, seepage and corrosion to the expansion joint, thus improving the service life of the expansion joint.

[0010] Optionally, a base plate is provided on the lower surface of both ends of the cover plate and above the drainage ditch, and the base plate is supported by a structural inverted retaining wall.

[0011] By adopting the above technical solution, by setting a base plate on the lower surface of both ends of the cover plate and above the drainage ditch, the stress-bearing area of ​​the cover plate is increased, preventing the cover plate from bending and exposing the expansion joint between the concrete joints, which would cause water leakage and corrosion of the expansion joint.

[0012] Optionally, a waterstop is provided between the two structural inverted supports. The waterstop includes a drainage channel and connecting plates located on both sides of the drainage channel. The connecting plates are located between the corresponding structural inverted supports and the base plate.

[0013] By adopting the above technical solution, the drainage channel of the waterstop strip drains the water that enters the expansion joint, and the connecting plate of the waterstop strip guides the water to the drainage ditch, reducing the leakage and corrosion of the expansion joint caused by water accumulation.

[0014] Optionally, sealant is provided between the cover plate and the concrete joint.

[0015] By adopting the above technical solution, sealant is filled into the gap between the cover plate and the concrete joint to prevent moisture from entering the expansion joint through the gap.

[0016] Optionally, a first drainage trough is provided between the two concrete joints and below the expansion joint, and the two sides of the first drainage trough are fixedly connected to the lower surface of the corresponding concrete joint.

[0017] By adopting the above technical solution and setting the first drainage trough below the expansion joint, the water entering the expansion joint can be effectively drained away, preventing the water from causing corrosion to the expansion joint.

[0018] Optionally, a second drainage trough is provided between the two concrete joints and below the first drainage trough, and a downwardly extending connecting plate is provided on the lower surface of the two concrete joints, with the two sides of the second drainage trough connected to the corresponding connecting plate.

[0019] By adopting the above technical solution, the second drainage trough is fixed below the first drainage trough by a connecting plate, which drains away the water that seeps out of the first drainage trough and further prevents water from seeping into the expansion joint and causing corrosion.

[0020] Optionally, sealing gaskets are provided between the two sides of the second drainage trough and the corresponding connecting plates, and the sealing gaskets are provided along the length direction of the connecting plates.

[0021] By adopting the above technical solution, sealing the space between the second drainage channel and the connecting plate with a sealing gasket can effectively prevent water from seeping out of the second drainage channel and causing corrosion to the expansion joint.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. At the concrete joint on both sides of the expansion joint, a structural curb is installed at the expansion joint. A drainage ditch is set between the structural curb and the concrete joint. The structural curb blocks the water from flowing into the drainage ditch. A cover plate is installed on the installation groove formed on the structural curb to prevent water from entering the expansion joint. A base plate is used to increase the contact area of ​​the cover plate and reduce its deformation. The gap between the cover plate and the concrete joint is sealed with sealant, which can effectively prevent water from outside the expansion joint from causing leakage.

[0024] 2. A steel mesh is installed at the bottom of the expansion joint to prevent falling objects from blocking the drainage channel during long-term use, which would cause water to seep into the expansion joint and cause corrosion.

[0025] 3. A first drainage trough and a second drainage trough are successively installed at the bottom of the anti-fall steel mesh to ensure that water seeping into the expansion joint can be discharged smoothly, and to avoid excessive water leakage causing corrosion to the expansion joint. A sealing gasket is installed between the second drainage trough and the fixed connection plate to prevent water from seeping out from the second drainage trough and causing corrosion to the expansion joint, which would pose a hidden danger to the safety of the building.

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail below.

[0030] A high-durability expansion joint protection structure, referring to Figure 1The system includes a concrete joint 1 and an expansion joint 2 located between the two concrete joints 1. The concrete joint 1 has a structural retaining wall 3 formed by concrete pouring at the expansion joint 2. A drainage ditch 4 is embedded between the concrete joint 1 and the structural retaining wall 3. The drainage ditch 4 is fixed to the structural retaining wall 3 by waterproof bolts. A fall-prevention steel mesh 7 is fixed between the concrete joints 1 below the expansion joint 2 by waterproof bolts. The fall-prevention steel mesh 7 is made of stainless steel. A base plate 8 is set above the expansion joint 2 and fixed to the structural retaining wall 3 by waterproof bolts. A cover plate 6 on the base plate 8 is fixed by waterproof bolts. Both the cover plate 6 and the base plate 8 are made of stainless steel. The gap between the cover plate 6 and the concrete joint 1 is filled with sealant 10, which is waterproof sealant. A connecting plate 92 of a waterstop 9 is fixed between the structural retaining walls 3 by waterproof bolts. The waterstop 9 includes a drainage channel 91 and a connecting plate 92. The connecting plate 92 of the waterstop 9 extends to the drainage ditch. The waterstop 9 is a rubber waterstop.

[0031] refer to Figure 1 and Figure 2 A connecting plate 12 is fixed to the lower part of the concrete joint 1 on both sides of the expansion joint 2 with waterproof bolts. The first drainage trough 11 is fixed to the connecting plate 12 with waterproof bolts. The first drainage trough 11 is located below the anti-fall steel mesh 7. The second drainage trough 13 below the first drainage trough 11 is fixed to the connecting plate 12 with waterproof bolts. The first drainage trough 11, the second drainage trough 13 and the connecting plate 12 are made of stainless steel. A sealing gasket 14 is fixed to the connection between the connecting plate 12 and the second drainage trough 13 with waterproof bolts. The sealing gasket 14 is a rubber sealing gasket, which seals the connection between the connecting plate 12 and the second drainage trough 13.

[0032] The implementation principle of this application embodiment is as follows:

[0033] Structural curbs 3 are fixed to the concrete extensions on both sides of the expansion joint 2. A drainage ditch 4 is fixed between the structural curb 3 and the concrete connection 1. The drainage ditch 4 drains away the water that enters the expansion joint 2. A fall-prevention steel mesh 7 is fixedly connected between the concrete connection 1 on both sides of the expansion joint 2. The fall-prevention steel mesh 7 blocks falling objects generated during long-term use of the expansion joint 2, preventing them from clogging the drainage channel. A cover plate 6 is installed in the mounting groove 5 on the upper surface of the structural curb 3 to prevent water from entering the expansion joint 2. The lower surface of the cover plate 6 is connected to the drainage channel. A base plate 8 is fixed above the trench 3. The base plate 8 increases the stress area of ​​the cover plate 6 and reduces the corrosion caused by water seepage in the expansion joint 2 due to the deformation of the cover plate 6. The sealant 10 is filled into the gap between the cover plate 6 and the concrete connection part 1 to effectively block the water accumulation. A waterstop 9 is set above the structural retaining wall 3. The connecting plates 92 on both sides of the waterstop 9 extend to the drainage ditch. When water seeps into the base plate 8, the waterstop 9 will drain the water. When the water exceeds the height of the drainage groove of the waterstop 9, the waterstop 9 will send the water into the drainage ditch through the connecting plates 92.

[0034] A first drainage trough 11 is fixed below the expansion joint 2 between the concrete joints 1 and 2 to drain water that seeps into the expansion joint 2 and prevent corrosion. A second drainage trough 13 is installed below the first drainage trough 11 to collect water that seeps out of the first drainage trough 13 and prevent it from corroding the expansion joint 2. A sealing gasket is installed at the connection between the second drainage trough 13 and the connecting plate 12 to prevent water seepage. This gives the expansion joint the triple protection capabilities of "leakage prevention," "falling object prevention," and "corrosion prevention," extending its service life and ensuring the safety of the building during use.
