Description

Technical Field

[0001] The utility model relates to the technical field of ground-connected wall sheet pile supporting structures, in particular to a ground-connected wall anchor reinforcement protection structure. Background Art

[0002] Ground-connected walls are mainly used in ground-connected wall sheet pile wharf structures and subway station support structures. According to the construction process of ground-connected walls, the over-filling height of ground-connected wall concrete is generally about 0.5-0.8 meters. The over-filling concrete of the ground-connected wall will wrap the anchor bars of the ground-connected wall, forming a large bond force. Before the construction of the upper structure of the ground-connected wall, it is necessary to peel off the over-filling concrete of the ground-connected wall from the concrete wrapped by the anchor bars, and then hoist the over-filling concrete of the ground-connected wall.

[0003] The underground continuous wall is a foundation project that uses a trenching machine on the ground to dig a long and narrow deep trench along the peripheral axis of the deep excavation project under the condition of mud wall protection. After the trench is cleared, a steel cage is suspended in the trench, and then underwater concrete is poured using the conduit method to form a unit trench section. This process is carried out section by section to build a continuous reinforced concrete wall underground as a water-cutting, anti-seepage, load-bearing, and water-retaining structure. At the same time, the anchor bars used in the ground-connected wall are easily subject to collision, so corresponding protective structures are required.

[0004] However, the protection structure used in the existing ground-connected wall does not have the function of continuous left-right assembly. Therefore, when protecting multiple steel bars, the protection structure is prone to position rotation after use. At the same time, because the protection structure does not have an interlocking structure for use, when using screws to assemble the front and rear protection structures, the screws are prone to slipping, resulting in loose assembly, making the protection structure assembly unable to be used stably. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a ground-connected wall anchor reinforcement protection structure, in which the T-shaped bar is located in the internal position of the T-shaped groove so as to assemble the left and right protection plates to ensure that the structure will not rotate at any position, and at the same time, through the mutual engagement of two locking toothed rings, the two screws can cooperate with each other to rotate, thereby ensuring the stable assembly of the front and rear protection plates.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A ground-connected wall anchor bar protection structure comprises a protection plate, wherein the back side of the protection plate is provided with a semicircular notch, the front side is provided with a screw hole, the right end face is provided with a T-shaped bar and the left end face is provided with a T-shaped slot, the T-shaped bar corresponds to the T-shaped slot, the screw hole passes through the body of the protection plate, there are multiple screw holes and they are distributed on both sides of the semicircular notch, and a rotating plate is provided in the screw hole.

[0008] There are four screw holes, and two screw holes are distributed on one side of the semicircular notch.

[0009] One end of a linkage rod is connected to the rotating plate, and the other end of the linkage rod is connected to a screw rod, the screw rod corresponds to the screw hole, and the length of the screw rod is greater than twice the length of the screw hole.

[0010] The linkage rod is sleeved with a locking toothed ring and a spring, the linkage rod is evenly provided with a plurality of strip grooves, the locking toothed ring is evenly provided with a plurality of clamping strips, the clamping strips are movably arranged in the strip grooves, one end of the spring is connected to the locking toothed ring, and the other end is connected to the rotating plate.

[0011] In the two screw holes on one side, the locking toothed rings corresponding to the two screw holes are meshed with each other, and the length of the linkage rod is greater than the width of the locking toothed ring.

[0012] The beneficial effects of the utility model are:

[0013] 1. When assembling the two protection plates on the left and right sides, the T-shaped bar can be slid and inserted into the internal position of the T-shaped slot, so that the two protection plates on the left and right sides can be installed. At the same time, when disassembling, the T-shaped bar can be slid out of the inside of the T-shaped slot to disassemble the protection plate, so that the protection structure will not rotate at any position when in use.

[0014] 2. By meshing the two locking toothed rings with each other, when a single screw is screwed out, it can drive the locking toothed ring connected to it to rotate, thereby the locking toothed ring will drive the other locking toothed ring meshed with it to rotate, thereby driving the screw to rotate inside the screw hole, so that the screw is tightened, the distance between the two protection plates will not be deviated, and the assembly stability of the protection structure is improved.

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Implementation 1

[0023] like Figures 1 to 5 As shown, a ground-connected wall anchor reinforcement protection structure includes a protection plate 1, the back side of the protection plate 1 is provided with a semicircular notch 101, the front side is provided with a screw hole 102, the right end face is provided with a T-shaped bar 103 and the left end face is provided with a T-shaped slot 104, the T-shaped bar 103 corresponds to the T-shaped slot 104, the screw hole 102 passes through the body of the protection plate 1, the screw hole 102 is multiple and distributed on both sides of the semicircular notch 101, and a rotating plate 2 is provided in the screw hole 102.

[0024] There are four screw holes 102 , and two screw holes 102 are distributed on one side of the semicircular notch 101 .

[0025] One end of a linkage rod 201 is connected to the rotating plate 2 , and the other end of the linkage rod 201 is connected to a screw rod 202 . The screw rod 202 corresponds to the screw hole 102 , and the length of the screw rod 202 is greater than twice the length of the screw hole 102 .

[0026] The linkage rod 201 is sleeved with a locking toothed ring 3 and a spring 302, a plurality of strip grooves 203 are evenly distributed on the linkage rod 201, a plurality of clamping strips 301 are evenly distributed in the locking toothed ring 3, the clamping strips 301 are movably arranged in the strip grooves 203, one end of the spring 302 is connected to the locking toothed ring 3, and the other end is connected to the rotating plate 2.

[0027] In the two screw holes 102 on one side, the locking toothed rings 3 corresponding to the two screw holes 102 are meshed with each other, and the length of the linkage rod 201 is greater than the width of the locking toothed ring 3 .

[0028] The T-bar 103 is located inside the T-slot 104 so that the left and right protection plates 1 can be assembled to ensure that the structure does not rotate at any position. At the same time, through the mutual engagement of the two locking tooth plates, the two screws 202 can rotate in coordination with each other to ensure that the front and rear protection plates 1 are assembled stably.

[0029] Specifically, two protective plates 1 are symmetrically arranged in the front and rear directions; semicircular notches 1 are provided in the middle positions of the opposite sides of the two protective plates 1, and the two semicircular notches 1 are arranged opposite to each other, and the two semicircular notches 1 wrap the anchoring bars inside; a T-shaped bar 103 is fixed in the middle position of the right end face of the protective plate 1, and a T-shaped slot 104 is provided in the middle position of the left end face of the protective plate 1, and the T-shaped slot 104 is arranged in the direction opposite to the T-shaped bar 103. When assembling the two protective plates 1 on the left and right sides, the T-shaped bar 103 can be slidably inserted into the inner position of the T-shaped slot 104, so that the two protective plates 1 on the left and right sides can be assembled. The plate 1 is installed. When disassembling, the T-shaped bar 103 can be slid out of the T-shaped groove 104 to disassemble the protection plate 1. Two rotating plates 2 which are symmetrical up and down are arranged on the front end surface of the protection plate 1. Screw holes 102 are penetrated at the positions of the front end surface of the protection plate 1 corresponding to the rotating plate 2. A linkage rod 201 is fixed to the middle position of the rear end surface of the rotating plate 2. A screw 202 is fixed to the rear end surface of the linkage rod 201, and the screw 202 can be screwed into the screw hole 102. The circumferential side of the linkage rod 201 is sleeved with a locking toothed ring 3, and two adjacent locking toothed rings 3 are meshed with each other.

[0030] By using the above-mentioned structure, when it is necessary to protect the steel bars of the ground-connected wall, the protection plate 1 can be set on the circumferential side of the steel bars, so that the steel bars are located between the two semicircular notches 101. At this time, the screw 202 is screwed into the screw hole 102, so that the screw 202 will spirally assemble the two front and rear protection plates 1, so that the two protection plates 1 can clamp the steel bars and protect the steel bars. At the same time, in order to improve the assembly stability between the two protection plates 1, the two locking toothed rings 3 can be meshed with each other. Therefore, when a single screw 202 is spirally disengaged, it can drive the locking toothed ring 3 connected to it to rotate, and the locking toothed ring 3 will drive the other locking toothed ring 3 meshed with it to rotate, thereby driving the screw 202 to rotate inside the screw hole 102, so that the screw 202 is tightened, so that the distance between the two protection plates 1 will not deviate.

[0031] Implementation 2

[0032] By sliding the T-shaped bar 301 into the inner position of the bar groove 203 , the two meshed locking toothed rings 3 can be staggered to facilitate the removal of the protective plate 1 .

[0033] Specifically, the screw hole 102 passes through the rear end face position of the protective plate 1, and the screw rods 202 are respectively spirally located in the internal position of the screw hole 102 located at the rear position thereof, and the rear end face of the linkage rod 201 is flush with the front end face of the protective plate 1 located in the front, and the rod diameter of the linkage rod 201 is larger than the aperture of the screw hole 102. Four strip grooves 203 evenly distributed in a ring shape are opened on the circumference of the linkage rod 201, and the strip groove 203 is fixed on the inner side surface of the locking gear ring 3. The clamping strip 301 slides in the internal position of the strip groove 203. The length of the strip groove 203 is consistent with the length of the linkage rod 201, and the length of the strip block 301 is consistent with the width of the locking gear ring 3.

[0034] Since the clamping strip 301 slides in the internal position of the strip groove 203, in order to facilitate the screw 202 to be screwed out from the internal position of the screw hole 102, the locking tooth ring 3 can be moved toward the rotating plate 2, whereby the locking tooth ring 3 will drive the clamping strip 301 to slide in the internal position of the strip groove 203, thereby causing the two meshing locking tooth rings 3 to be staggered with each other and prevent them from meshing, thereby facilitating the rotation of the rotating plate 2 and screwing out the screw 202 from the internal position of the screw hole 102, so that the two front and rear protective plates 1 can be disassembled.

[0035] Implementation 3

[0036] The spring 302 pushes the locking toothed ring 3 so that the two locking toothed rings 3 can be stably meshed.

[0037] Specifically, the front end face of the locking gear ring 3 is fixed with a spring 302, the spring 302 is slidably sleeved on the circumferential side of the linkage rod 201, and the front end face of the spring 302 is connected to the rear end face of the rotating plate 2, the T-shaped groove 104 passes through the upper and lower end faces of the protective plate 1, and the length of the T-shaped strip 103 is consistent with the length of the T-shaped opening 104.

[0038] The spring 302 pushes the locking toothed ring 3 so that the locking toothed ring 3 can be stably abutted against the protection plate 1, so that the locking toothed ring 3 will not deviate arbitrarily on the peripheral side of the linkage rod 201, thereby ensuring stable meshing of the two locking toothed rings 3.

For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
