Description

Technical Field

[0001] The present invention relates to the field of subgrade engineering, and particularly to a protection structure for a copper sheet for subgrade water stop. Background Technique

[0002] In road construction, the subgrade is the basic part of the road structure, and its stability is crucial to the overall performance of the road. However, due to the influence of natural factors and vehicle loads, the subgrade often faces the problem of water erosion. The intrusion of water will cause the strength of the subgrade materials to decline, and even phenomena such as softening and disintegration will occur, seriously affecting the service life of the road and driving safety. Traditional subgrade waterproof measures mostly use waterproof membranes or drainage systems. At present, there are various subgrade waterproof materials and technologies on the market, but most of the materials have problems such as poor durability, high construction difficulty, and high cost.

[0003] The subgrade is usually cast with concrete, and expansion joints are provided. When casting concrete, copper sheets are embedded across the joints for water stop. When the existing copper sheet water stop is embedded, it is basically embedded by the method of folding and extrusion. However, when squeezing the two sides of the copper sheet, the copper sheet is relatively soft and difficult to insert into the expansion joint, and problems such as skewed folding at the folding place are likely to occur. For this reason, we propose a protection structure for a copper sheet for subgrade water stop. Summary of the Invention

[0004] The purpose of the present invention is to provide a protection structure for a copper sheet for subgrade water stop to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] A protection structure for a copper sheet for subgrade water stop includes a device housing and a copper sheet body arranged inside the device housing. A movable plate is arranged at the top of the device housing, and a pressing box is fixedly installed at the bottom of the movable plate. The copper sheet body is folded and inserted into the expansion joint through the pressing box; it further includes: a pushing and pressing mechanism for pushing and pulling the copper sheet body into the expansion joint, the pushing and pressing mechanism is installed inside the device housing, there are two groups of the pushing and pressing mechanisms, and the pressing box is located between the two pushing and pressing mechanisms; a wall abutting mechanism for pressing and contacting the device housing and the concrete, the wall abutting mechanism is installed at the bottom of the device housing; a compression reducing mechanism for folding and pressing the copper sheet body into the expansion joint, the compression reducing mechanism is installed inside the pressing box.

[0007] Preferably, the pressing mechanism includes a sliding seat installed inside the device housing. Both sides of the sliding seat are in contact with the inner side of the device housing. The sliding seat can move inside the device housing. A frame-shaped perforation for inserting the copper sheet body is formed on the surface of the sliding seat. A pressing plate is limitedly slidable inside the frame-shaped perforation. The bottom of the pressing plate is in contact with the top of the copper sheet body. Three equally spaced insertion posts are fixedly connected to the top of the pressing plate. A sliding cavity for the limited sliding of the insertion posts is formed on the top inner wall of the frame-shaped perforation. Three equally spaced first springs are fixedly connected between the pressing plate and the top inner side of the frame-shaped perforation. The three insertion posts are respectively located inside the three first springs. By using the elasticity of the first springs, the pressing plate can be made to press against the surface of the copper sheet body for positioning. Two pressing blocks symmetrically distributed at both ends of the pressing plate are arranged on the top of the sliding seat. A pressing groove for the limited sliding of the pressing blocks is formed on the top of the sliding seat. The contact surfaces between the pressing groove and the pressing blocks are both inclined plane structures. When the pressing blocks move downward, the two sliding seats can be pushed to move towards each other along the inner side of the device housing. The pressing blocks are fixedly installed on the top of the movable plate. Mounting blocks are fixedly connected to both end faces of the sliding seat. Slide bars are fixedly connected to the corresponding faces of the two mounting blocks. The two slide bars are symmetrically distributed up and down. Slide blocks are fixedly connected to the corresponding faces of the two slide bars. A long strip-shaped sliding cavity for the limited sliding of the slide blocks is formed on the surface of the slide bars. A guiding bar is fixedly connected inside the long strip-shaped sliding cavity of the slide bars. A sliding hole for the limited sliding of the guiding bar is formed on the surface of the slide blocks. The slide blocks on the two slide bars can both move along the outer sides of the corresponding guiding bars, achieving the effects of elongation and contraction. A second spring is fixedly connected between the two mounting blocks. The slide bars are located inside the second spring, facilitating the pushing of the two sliding seats to move away and reset. When the movable plate moves downward, it can move along the inclined plane of the pressing groove through the inclined plane of the pressing blocks, causing the two sliding seats to move towards each other. The pressing box on the movable plate presses the top of the copper sheet body. As the sliding seat moves, the copper sheet body can be inserted into the expansion joint of the concrete, achieving the effect of quickly embedding the copper sheet and facilitating water stop and protection.

[0008] Preferably, the wall abutting mechanism includes two guiding bars symmetrically arranged outside the mounting block. The guiding bars are fixedly installed inside the device housing. A plurality of equally spaced balls are rotatably installed on one side of the guiding bar close to the sliding seat. A spherical chute for limiting the sliding of the balls is formed on the end face of the sliding seat to facilitate the movement of the sliding seat. An anti-slip roller is arranged below the mounting block to abut against the surface of the concrete wall to achieve the effect of anti-slip positioning. A rhombic insert bar is rotatably installed at one end of the anti-slip roller. The rhombic insert bar is inserted into the device housing in a limited manner. A third spring is fixedly connected between the end of the rhombic insert bar away from the anti-slip roller and the inside of the device housing. A first sliding column is fixedly connected to the outside of the rhombic insert bar. A first long slot for limiting the sliding of the first sliding column is formed on the outside of the device housing to provide limitation for the movement of the rhombic insert bar. The four anti-slip rollers can abut against the concrete wall surface and compress the third spring to make the copper sheet body on the device housing lean against the expansion joint, preventing the situation of skew and deviation during the embedding of the copper sheet body. Moreover, when the sliding seat moves, the mounting block can move between the two guiding bars, and the balls reduce the friction during the movement of the sliding seat, achieving the effect of precise positioning and facilitating the embedding of the copper sheet body.

[0009] Preferably, the compression mechanism includes a movable block that is limited to slide inside the pressing box. An activity bar is arranged at the bottom of the movable block. Three pressing rods that slide through the movable block are fixedly connected to the top of the activity bar. The pressing rods are fixedly installed at the bottom of the movable plate. Three fourth springs are fixedly connected between the top of the movable block and the movable block. The fourth springs suspend the movable block at the bottom of the movable plate. The three pressing rods are respectively located inside the three fourth springs. V-shaped folding rods are rotatably installed at both ends of the activity bar. A pressing strip is rotatably installed between the two ends of the two V-shaped folding rods. The end face of the pressing strip away from the V-shaped folding rod is an arc structure. Two symmetrically distributed inclined sliding strips are fixedly connected to the end face of the pressing strip close to the V-shaped folding rod. A sleeve block that is movably sleeved outside the inclined sliding strip is fixedly connected to the bottom of the movable block. When the activity bar moves downward, it can pull the inclined sliding strip on the pressing strip to move along the inside of the sleeve block through the V-shaped folding rod, causing the two pressing strips to approach each other. Slide columns II are fixedly connected to both sides of the movable block. Second long slots for limiting the sliding of the slide columns II are formed on the outside of the pressing box to provide limitation for the movement of the movable block. When the movable plate moves downward, the two pressing strips below the pressing box can abut against the upper surface of the copper sheet body to fold the copper sheet body. And when the movable block continues to move, the pressing rods can make the included angle of the V-shaped folding rod fold and pull the pressing strip to move through the activity bar, so that the inclined sliding strip on the pressing strip moves along the inside of the sleeve block, and the two pressing strips can move towards each other when moving downward, being able to reduce the included angle of the copper sheet body and facilitating insertion into a smaller expansion joint.

[0010] Preferably, the four corners of the movable plate are all long convex strip structures, and electric telescopic rods are fixedly installed between the four corners of the movable plate and the device housing for pulling the movable plate to move up and down.

[0011] Preferably, a control panel for operating the electric telescopic rods is installed on the top of the movable plate, which is convenient for synchronously operating the four electric telescopic rods.

[0012] Preferably, two observation holes symmetrically distributed outside the control panel are opened on the top of the movable plate, which is convenient for observing the embedding situation of the copper sheet body.

[0013] Preferably, two grips symmetrically distributed on both sides of the movable plate are fixedly connected to the top of the device housing for bringing the device housing close to the expansion joint.

[0014] Preferably, two side plates symmetrically distributed are fixedly connected to the top of the pressing plate, a guiding groove for the side plates to slide in a limited manner is opened on the outside of the sliding seat, and long strip-shaped anti-slip lines are opened on the bottom of the pressing plate, which is convenient for pushing the copper sheet body to move.

[0015] Preferably, a plurality of mating slots distributed crosswise and equidistantly are opened on the end faces of the two pressing strips away from the V-shaped folding rod, which is convenient for the two pressing strips to lean against each other to form an arc shape.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. Through the pushing mechanism of the present invention, when the movable plate moves downward, it can move along the inclined surface of the pressure groove through the inclined surface of the pressing block, so that the two sliding seats move towards each other. The pressing box on the movable plate presses the top of the copper sheet body. As the sliding seat moves, while pressing the copper sheet body, it also pushes both ends of the copper sheet body, and the copper sheet body can be inserted into the expansion joint of the concrete, thus achieving the effect of quickly embedding the copper sheet and facilitating water stop and protection.

[0018] 2. Through the wall abutting mechanism of the present invention, the four anti-slip rollers can abut against the concrete wall surface and compress the spring three to make the copper sheet body on the device housing lean against the expansion joint, preventing the situation of skew and deviation when embedding the copper sheet body. The mounting block on the sliding seat can move along between the two guiding strips, and the balls reduce the friction when the sliding seat moves, thus achieving the effect of accurate positioning and facilitating the embedding of the copper sheet body.

[0019] 3. Through the compression mechanism of the present invention, the movable plate can make the two pressing strips below the pressing box fold the copper sheet body. The pressing rod makes the included angle of the V-shaped folding rod fold and pull the pressing strip to move through the movable strip, so that the inclined sliding strip on the pressing strip moves along the inner side of the sleeve block, and the two pressing strips can move towards each other when moving downward, and the included angle of the copper sheet body can be reduced, thus achieving the effect of quickly inserting the copper sheet body into a smaller expansion joint.

Three equally spaced spring 1s 304 are fixedly connected between the pressing plate 302 and the inner side of the top of the frame-shaped perforation. The three insertion posts 303 are respectively located inside the three spring 1s 304. Using the elasticity of the spring 1s 304, the pressing plate 302 can be made to abut against the surface of the copper sheet body 2 for positioning. Two pressing blocks 305 symmetrically distributed at both ends of the pressing plate 302 are provided on the top of the sliding seat 301. A pressing groove for limiting the sliding of the pressing blocks 305 is provided on the top of the sliding seat 301.

[0033] The user inserts the copper sheet body 2 into the frame-shaped perforations of the two sliding seats 301. The first spring 304 pushes the pressing plate 302 to press against the top of the copper sheet body 2 for positioning. Subsequently, the movable plate 6 drives the pressing block 305 and the pressing box 7 to move downward. The inclined surface of the pressing block 305 moves along the inclined surface of the pressing groove, causing the two sliding seats 301 to move towards each other. At the same time, the pressing box 7 presses the top of the copper sheet body 2. As the sliding seats 301 move, the two ends of the copper sheet body 2 are synchronously pushed, and the copper sheet body 2 is inserted into the expansion joint of the concrete, achieving the effect of quickly pre-burying the copper sheet and facilitating water stop protection.

[0034] Please refer to Figure 5 , in the illustrated abutting wall mechanism 4, there are two guide bars 401 symmetrically arranged outside the mounting block 306. The guide bars 401 are fixedly installed on the inner side of the device housing 1. A plurality of equally spaced balls 402 are rotatably installed on the side of the guide bar 401 close to the sliding seat 301. A spherical chute for the balls 402 to be limited and slide is provided on the end surface of the sliding seat 301, facilitating the movement of the sliding seat 301. A non-slip roller 403 is provided below the mounting block 306, which is used to press against the surface of the concrete wall to achieve the effect of anti-slip positioning. One end of the non-slip roller 403 is rotatably installed with a rhombic insert 404. The rhombic insert 404 is limited and inserted into the interior of the device housing 1. A third spring 405 is fixedly connected between the end of the rhombic insert 404 away from the non-slip roller 403 and the interior of the device housing 1.

A first long slot for the first sliding column 406 to be limited and slide is provided on the outside of the device housing 1 to provide a limit for the movement of the rhombic insert 404;

[0035] The user brings the device housing 1 close to the expansion joint of the concrete, so that the four non-slip rollers 403 press against the concrete wall surface, and compresses the third spring 405 to make the copper sheet body 2 on the device housing 1 close to the expansion joint, preventing the situation of skew and deviation when pre-burying the copper sheet body 2. When the two sliding seats 301 move, they drive the mounting block 306 to move along between the two guide bars 401. At the same time, the sliding seat 301 moves along the balls 402, reducing the friction when the sliding seat 301 moves, achieving the effect of accurate positioning and facilitating the pre-burying of the copper sheet body 2.

[0036] Please refer to Figures 6 - 8, the pressure reducing mechanism 5 in the illustration includes a movable block 501 that is limited and slides inside the pressing box 7. A movable bar 502 is provided at the bottom of the movable block 501. Three pressing rods 503 that slide through the movable block 501 are fixedly connected to the top of the movable bar 502. The pressing rods 503 are fixedly installed at the bottom of the movable plate 6. Three springs four 504 are fixedly connected between the top of the movable block 501 and the movable block 501. The springs four 504 suspend the movable block 501 at the bottom of the movable plate 6. The three pressing rods 503 are respectively located inside the three springs four 504. V-shaped folding rods 505 are rotatably installed at both ends of the movable bar 502. A pressing strip 506 is rotatably installed between the two ends of the two V-shaped folding rods 505. The end face of the pressing strip 506 away from the V-shaped folding rod 505 is an arc structure. Two symmetrically distributed inclined sliding strips 507 are fixedly connected to the end face of the pressing strip 506 close to the V-shaped folding rod 505. A sleeve block 508 that movably sleeved outside the inclined sliding strip 507 is fixedly connected to the bottom of the movable block 501. When the movable bar 502 moves downward, it can pull the inclined sliding strip 507 on the pressing strip 506 to move along the inside of the sleeve block 508 through the V-shaped folding rod 505, so that the two pressing strips 506 are close to each other. Slide columns two 509 are fixedly connected to both sides of the movable block 501. A long strip groove two for the slide column two 509 to be limited and slide is opened on the outside of the pressing box 7 to provide a limit for the movement of the movable block 501;

[0037] When the movable plate 6 moves towards the expansion joint, it drives the movable block 501 in the pressing box 7 to move synchronously, so that the two pressing strips 506 below the movable block 501 abut against the upper surface of the copper sheet body 2, and reversely pushes the movable block 501 to move along the inside of the pressing box 7 and the outside of the pressing rod 503, compressing the spring three 405 so that the movable bar 502 on the pressing rod 503 pushes the V-shaped folding rod 505 to fold and pull the inclined sliding strip 507 on the pressing strip 506 to move along the inside of the sleeve block 508, so that the two pressing strips 506 are close to each other, and the folding angle of the pressing strip 506 on the copper sheet body 2 can be reduced, which is convenient for inserting the copper sheet body 2 into a smaller expansion joint.

[0038] The working principle of pre-embedding the copper sheet body 2 into the expansion joint is as follows: first, the user inserts the copper sheet body 2 into the frame-shaped perforations of the two slide seats 301, and the spring 1 304 pushes the pressure plate 302 against the top of the copper sheet body 2 for positioning. Then, the user moves the device housing 1 close to the expansion joint of the concrete, so that the four anti-skid rollers 403 are against the concrete wall, and compresses the spring 3 405 to make the copper sheet body 2 on the device housing 1 lean against the expansion joint. Then, the user moves the movable plate 6 toward the direction of the expansion joint, so that the pressure block 305 moves synchronously with the pressure box 7, and the inclined surface of the pressure block 305 moves along the inclined surface of the pressure groove, so that the two slide seats 301 move toward each other, and the two ends of the copper sheet body 2 are synchronously pushed by the pressure plate 302. At the same time, the movable block in the pressure box 7 501 moves synchronously, so that the two pressure strips 506 under the movable block 501 press against the upper surface of the copper sheet body 2, and push the movable block 501 in the opposite direction to move along the inner side of the pressure box 7 and the outer side of the pressure rod 503, and the compression spring three 405 makes the movable bar 502 on the pressure rod 503 push the V-shaped folding rod 505 to fold and pull the inclined sliding bar 507 on the pressure strip 506 to move along the inner side of the sleeve block 508, so that the two pressure strips 506 are close to each other, and the folding angle of the pressure strip 506 to the copper sheet body 2 can be reduced. Finally, the pressure plate 302 pushes the two ends of the copper sheet body 2, and the pressure strip 506 presses the upper surface of the copper sheet body 2, so that the copper sheet body 2 can be inserted into the smaller expansion joint, thereby achieving the effect of quickly embedding the copper sheet, which is convenient for water-stopping protection of the expansion joint.

[0039] Embodiment 2

[0040] See also Figure 2 and Figure 3 The present embodiment further explains the first embodiment. The four corners of the movable plate 6 in the figure are all long convex strip structures. Electric telescopic rods 8 are fixedly installed between the four corners of the movable plate 6 and the device housing 1, which are used to pull the movable plate 6 up and down. A control panel 9 for operating the electric telescopic rods 8 is installed on the top of the movable plate 6, which is convenient for synchronous operation of the four electric telescopic rods 8. Two observation holes are symmetrically distributed on the outside of the control panel 9 on the top of the movable plate 6, which are convenient for observing the embedded situation of the copper sheet body 2. Two handles 10 symmetrically distributed on both sides of the movable plate 6 are fixedly connected to the top of the device housing 1, which are used to bring the device housing 1 close to the expansion joint.

[0041] In this embodiment: the user can hold the two handles 10 to place the bottom of the device housing 1 against the expansion joint, and start the four electric telescopic rods 8 to move the movable plate 6 through the control panel 9. When pre-embedding the copper sheet body 2, the user can observe the pre-embedding status of the copper sheet body 2 through the two observation holes, which facilitates the operation.

[0042] Embodiment 3

[0043] See also Figures 2 - 7, this embodiment further illustrates other embodiments. In the figure, two symmetrically distributed side plates 11 are fixedly connected to the top of the pressing plate 302. A guiding groove for the limited sliding of the side plates 11 is provided on the outer side of the sliding seat 301. A long strip-shaped anti-slip pattern is provided on the bottom of the pressing plate 302 to facilitate the pushing of the copper sheet body 2 to move. A plurality of mating slots that are cross-arranged and equally spaced are provided on the end faces of the two pressing strips 506 away from the V-shaped folding rod 505, facilitating the two pressing strips 506 to lean against each other to form an arc shape.

[0044] In this embodiment: When the user inserts the copper sheet body 2 into the frame-shaped through holes of the two sliding seats 301, the side plates 11 on the pressing plate 302 move along the guiding groove, and the anti-slip pattern facilitates the fixing of the copper sheet body 2, facilitating the installation of copper sheet bodies 2 with different thicknesses.
