Description

Technical Field

[0001] This application relates to the field of pavement construction technology, and in particular to a grout-proof structure for pavement construction. Background Technology

[0002] Currently, traditional concrete formwork requires drilling holes during the pouring process to insert bolts for fixing. These holes need to be welded and ground smooth after construction to allow for reuse of the formwork. However, this method can cause deformation of the formwork, shorten its service life, and the welding and grinding work increases construction costs and time.

[0003] The existing anti-grout leakage structure uses plastic plugging components, which include a plugging cap and an insertion tube. The outer wall of the insertion tube is equipped with multiple layers of fixing plates. The plugging components are inserted into the holes in the pavement construction template to seal them and prevent grout leakage during concrete pouring. The plugging components can be reused.

[0004] The existing technical solutions mentioned above have the following drawbacks: during the sealing process, the plastic parts are not elastic, and repeated use over a long period of time will cause the anti-leakage structure to loosen, resulting in an incomplete seal. Utility Model Content

[0005] This application provides a grout-proof structure for pavement construction to prevent loosening of the grout-proof structure after long-term use and to improve the grout-proof effect.

[0006] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0007] A grout-proof structure for pavement construction includes a sealing plate, a fixing cylinder, a fixing plate, fastening bolts, and a fastener. The fixing cylinder is coaxially fixed to the surface of the sealing plate, and the fixing plate is slidably disposed inside the fixing cylinder. The fastening bolts are threaded onto the sealing plate and rotatably connected at their ends to the fixing plate. A receiving hole is provided on the peripheral wall of the fixing cylinder, which connects the inner and outer walls of the fixing cylinder. The receiving hole includes an inner opening and an outer opening. One end of the fastener passes through the receiving hole and is hinged to the peripheral wall of the fixing plate. The fastener can be completely located in the receiving hole and will not rotate into the fixing cylinder.

[0008] By adopting the above technical solution, and by setting up a sealing plate, a fixing cylinder, a fixing plate, fastening bolts, and fasteners, when using the anti-leakage grouting structure, rotating the fastening bolts moves the fixing plate away from the sealing plate, storing the fasteners in the receiving hole. The anti-leakage grouting structure is then inserted into the hole of the pavement construction template, so that the surface of the sealing plate is in contact with the surface of the pavement construction template. Rotating the fastening bolts moves the fixing plate closer to the sealing plate, so that one section of the fastener is outside the fixing cylinder. Continuing to rotate the fastening bolts, the anti-leakage grouting structure is fixed by the fasteners. The sealing plate can seal the hole, preventing grout leakage during concrete pouring, which can lead to defects such as honeycomb, pitting, and exposed reinforcement on the concrete structure surface. The fixing cylinder, fixing plate, fastening bolts, and fasteners make the sealing of the hole by the anti-leakage grouting structure tighter and more secure, preventing the problem of loosening of the sealing of the hole after long-term repeated use.

[0009] Optionally, a protruding sliding member is fixedly connected to the peripheral wall of the fixing plate, the protruding sliding member is slidably disposed in the inner hole, and the end of the fixing member is hinged to the surface of the protruding sliding member away from the fixing plate.

[0010] By adopting the above technical solution and setting a protruding sliding component, the movement trajectory of the fixed plate can be restricted, thus preventing the fixed plate from rotating when the fastening bolts are turned.

[0011] Optionally, a limiting plate is fixed to the surface of the protruding slider near the sealing plate.

[0012] By adopting the above technical solution and setting a limiting plate, excessive rotation of the fixing parts can be avoided, which would reduce the fixing effect and cause the anti-grout leakage structure to loosen.

[0013] Optionally, the receiving hole wall is provided with an installation cavity, and the anti-leakage structure also includes a spring and a sliding sleeve. The spring is disposed in the installation cavity, and one end of the spring is fixedly connected to the end wall of the installation cavity near the sealing plate. The sliding sleeve is a cylinder closed at one end and is sleeved on the other end of the spring. The plate surface of the fixing member always abuts against the outer wall of the end of the sliding sleeve.

[0014] By adopting the above technical solution and setting springs and sliding sleeves, it is possible to ensure that the fixing parts can stably pass through the outer opening when fixing the anti-leakage grout structure, and to avoid the fixing parts getting stuck in the receiving hole. In conjunction with the sealing plate, the template used for pavement construction is clamped and fixed, thereby stably installing the anti-leakage grout structure in the hole and improving installation efficiency.

[0015] Optionally, the end of the receiving hole away from the sealing plate is machined into a flared shape, with the flared opening facing the sealing plate, and the fastener can be housed in the flared opening.

[0016] By adopting the above technical solution, the flared end receiving hole can accommodate the fastener, which facilitates the installation of the anti-leakage structure, avoids the fastener from obstructing the insertion and removal of the anti-leakage structure, and protects the fastener.

[0017] Optionally, the anti-leakage structure also includes a fixing nut, which is sleeved on the fastening bolt and located on the side of the sealing plate away from the fixing cylinder.

[0018] By adopting the above technical solution and setting a fixing nut, the position of the fastening bolt can be locked, thereby fixing the sealing ring and the position of the fastening bolt and preventing the anti-leakage device from loosening during use.

[0019] Optionally, the anti-leakage structure also includes a sealing ring, which is fitted onto the fastening bolt and located between the fixing nut and the sealing plate.

[0020] By adopting the above technical solution and setting a sealing ring, the threaded hole at the connection between the fastening bolt and the sealing plate can be sealed, thus preventing grout leakage at the threaded hole during concrete pouring.

[0021] Optionally, the end face of the fixing cylinder facing away from the sealing plate is machined into a curved surface with an arc.

[0022] By adopting the above technical solution, the arc surface of the fixed cylinder end face can enable the anti-grout leakage structure to be quickly installed and inserted into the hole, thereby improving installation efficiency.

[0023] In summary, this application has the following technical effects:

[0024] 1. By setting up a sealing plate, fixing cylinder, fixing plate, fastening bolts and fasteners, the sealing plate can seal the hole and prevent grout leakage during concrete pouring, which would cause defects such as honeycomb, pitting, and exposed reinforcement on the surface of the concrete structure. The fixing cylinder, fixing plate, fastening bolts and fasteners make the grout leakage prevention structure seal the hole more tightly and firmly, and prevent the grout leakage prevention structure from loosening after long-term repeated use.

[0025] 2. By setting up a protruding sliding component, the movement trajectory of the fixed plate can be restricted, preventing the fixed plate from rotating when the fastening bolts are turned;

[0026] 3. By incorporating springs and sliding sleeves, the fasteners can be stably protruded from the outer opening when fixing the anti-leakage grout structure, preventing them from getting stuck in the receiving hole. This, combined with the sealing plate, clamps and fixes the pavement construction template, thereby stably installing the anti-leakage grout structure in the hole and improving installation efficiency.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses a grout-proof structure for pavement construction, referring to... Figure 1 The anti-leakage structure includes an anti-leakage component 1 and a fixing component 2. The anti-leakage component 1 can be inserted into the holes of the pavement construction template to seal the holes and prevent grout leakage during concrete pouring, which would cause defects such as honeycomb, pitting, and exposed reinforcement on the concrete surface. The fixing component 2 can fix the anti-leakage component 1 into the holes of the pavement construction template, making the sealing of the holes more tight and firm, and preventing the hole sealing from loosening after long-term use.

[0033] Combination Figure 1 and Figure 2 The leak-proof component 1 includes a sealing plate 11, which is a circular plate. The diameter of the sealing plate 11 is larger than the diameter of the holes in the pavement construction template. The surface of the sealing plate 11 can fit against the surface of the template around the holes to seal them and prevent grout leakage during concrete pouring. The leak-proof component 1 also includes a fixing cylinder 12, which is fixed to the surface of the sealing plate 11. The fixing cylinder 12 is coaxially arranged with the sealing plate 11. The outer wall of the fixing cylinder 12 is adapted to the holes in the pavement construction template and can be inserted into the holes. The fixing cylinder 12 fixes the sealing plate 11. The end face of the fixing cylinder 12 away from the sealing plate 11 is processed to form a curved surface.

[0034] Combination Figure 1 and Figure 3The fixed cylinder 12 has a rectangular receiving hole 121 on its peripheral wall. The receiving hole 121 connects the inner and outer peripheral walls of the fixed cylinder 12. The length direction of the receiving hole 121 is parallel to the length direction of the fixed cylinder 12. There are three receiving holes 121. The three receiving holes 121 are evenly distributed at equal angles on the peripheral wall of the fixed cylinder 12 with the axis of the fixed cylinder 12 as the center. The receiving hole 121 includes an inner opening 122 and an outer opening 123. The length of the inner opening 122 is greater than the length of the outer opening 123. The end of the receiving hole 121 away from the sealing plate 11 is flared and faces the sealing plate 11. The fixing component 2 includes a fixing plate 21, which is a circular plate and is slidably disposed inside the fixing cylinder 12. The fixing plate 21 and the fixing cylinder 12 are coaxially arranged. The peripheral wall of the fixing plate 21 is in contact with the inner wall of the fixing cylinder 12. The end of the inner orifice 122 away from the sealing plate 11 is flush with the end wall of the receiving hole 121. Protruding sliding members 211 are evenly arranged at equal angles on the peripheral wall of the fixing plate 21. The protruding sliding members 211 are adapted to the inner orifice 122 and are slidably disposed in the receiving hole 121. The surface of the protruding sliding members 211 facing away from the sealing plate 11 can fit against the end wall of the receiving hole 121.

[0035] Combination Figure 2 and Figure 3 The fixing component 2 also includes a fastening bolt 22, a fixing nut 23, and a sealing ring 24. The fastening bolt 22 is threaded onto the sealing plate 11, and its end passes through the sealing plate 11 and is rotatably connected to the fixing plate 21. The fastening bolt 22, the fixing plate 21, and the sealing plate 11 are all coaxially arranged. The fixing nut 23 is threaded onto the fastening bolt 22 and is located on the side of the sealing plate 11 opposite to the fixing plate 21. The sealing ring 24 is fitted onto the fastening bolt 22 and is located between the fixing nut 23 and the sealing plate 11. The sealing ring 24 can seal the threaded connection between the fastening bolt 22 and the sealing plate 11 to prevent grout leakage.

[0036] Combination Figure 1 and Figure 3 The fixing assembly 2 also includes three sets of fixing structures 25, which are respectively disposed in three receiving holes 121. The fixing mechanism includes a fixing member 251, a spring 253, and a sliding sleeve 252. One end of the fixing member 251 passes through the receiving hole 121 and is hinged to the peripheral wall of the fixing plate 21. The fixing member 251 is a curved strip plate with the curved opening facing away from the sealing plate 11. The fixing member 251 can be completely housed in the receiving hole 121 and is located at the flared end of the receiving hole 121. A limiting plate 212 is fixedly attached to the surface of the protruding sliding member 211 near the sealing plate 11. The limiting plate 212 can prevent the fixing member 251 from rotating excessively away from the sealing plate 11.

[0037] Combination Figure 1 and Figure 3An installation cavity is formed on the wall of the receiving hole 121 near the sealing plate 11. The spring 253 is placed in the installation cavity, and one end of the spring 253 is fixedly connected to the bottom of the installation cavity. The sliding sleeve 252 is placed in the receiving hole 121. The sliding sleeve 252 is a cylinder with one end closed. The sliding sleeve 252 is sleeved on the end of the spring 253 away from the sealing plate 11. The other end of the spring 253 is fixedly connected to the inner wall of the closed end of the sliding sleeve 252. The arc-shaped protruding plate surface of the fixing member 251 always abuts against the outer wall of the closed end of the sliding sleeve 252, ensuring that the fixing member 251 can stably pass through the outer hole 123. Together with the sealing plate 11, it clamps and fixes the template for pavement construction, thereby stably installing the anti-leakage structure in the hole.

[0038] Combination Figure 1 and Figure 3 When using the anti-leakage structure, rotate the fastening bolt 22 to move the fixing plate 21 away from the sealing plate 11, and store the fixing member 251 in the receiving hole 121. Insert the anti-leakage structure into the hole of the pavement construction template, so that the surface of the sealing plate 11 is in contact with the surface of the pavement construction template. Rotate the fastening bolt 22 to move the fixing plate 21 closer to the sealing plate 11, so that one part of the fixing member 251 is outside the fixing cylinder 12, and the surface of the fixing member 251 abuts against the closed end of the sliding sleeve 252. Continue to rotate the fastening bolt 22 to fix the anti-leakage structure through the fixing member 251. Use the fixing nut 23 to fix the sealing ring 24 and the position of the fastening bolt 22 to prevent the anti-leakage device from loosening during use.

[0039] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
