Description

Technical Field

[0001] This invention relates to the field of retaining wall reinforcement positioning technology, and particularly to a cantilever retaining wall reinforcement positioning device. Background Technology

[0002] A cantilever retaining wall consists of a base slab and a vertical wall fixed to the base slab. Its stability is primarily maintained by the weight of the backfill on the base slab. It mainly comprises three reinforced concrete components: the vertical wall, the toe slab, and the heel slab. Therefore, during the construction of a cantilever retaining wall, positioning devices are needed to locate the reinforcing bars that need to be tied during construction, ensuring uniform distribution of the reinforcing bars and guaranteeing the strength of the cantilever retaining wall. Existing rebar positioning devices are used to locate the reinforcing bars in the cantilever retaining wall during construction. These devices are placed around the outer edge of the retaining wall to mark the distribution of the reinforcing bars. Typically, a marker pen is used to mark the rebar positions. However, during construction, these markings are easily erased, affecting the observation of the marked positions by construction workers. Furthermore, the style of the rebar positioning marks is relatively simple, leading to omissions when viewed from a distance. Summary of the Invention

[0014] The cantilever retaining wall reinforcement positioning device provided by the present invention has the following beneficial effects:

[0015] 1. By using a rotating reflector inside the protective cover, construction workers can easily view the position of the rebar positioning marks. When binding the rebar of a cantilever retaining wall, the protective cover is positioned at the location of the evenly distributed rebar markings, allowing for clear marking of the rebar's position. Compared to marking with a marker pen, this method provides clear marking without the problem of erasure. Furthermore, the protective cover is located outside the horizontal positioning tube, so it does not affect the binding of the inner rebar. Driven by the airflow and the rotating fan blades, the reflector on the outside of the reflector reflects light, allowing construction workers to observe the position of the rebar distribution marks from a distance. This provides a more intuitive view, facilitating quick and accurate construction and preventing errors in rebar binding due to missed markings.

[0016] Second, the number of marking plates can be increased or decreased according to the number of steel bars by the groove in the middle of the outer side of the horizontal positioning tube. The marking plates can drive the reflectors in the protective cover to match the number of steel bars. This makes the operation more convenient and allows for repeated use in the future, reducing unnecessary construction costs.

[0017] Third, by using the wall positioning tube and the wall-mounted positioning tube, which can be moved to different positions on the horizontal positioning tube and the horizontal telescopic rod under the action of the positioning clamp and the fixing clamp, the wall positioning tube and the wall-mounted positioning tube can accurately position the steel bars on the wall surface and the back of the cantilever retaining wall. The plinth positioning tube positions the steel bars at the plinth of the retaining wall. It can achieve good results in the positioning, inspection and acceptance of steel bars in the construction of cantilever retaining walls, and has good benefits such as small positioning deviation and accelerated steel bar construction progress.

[0033] To make the objectives, solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.

[0034] Please refer to Figures 1 to 8 As shown:

[0035] Example 1: This invention provides a cantilever retaining wall reinforcement positioning device, including a transverse positioning tube 1, which is cylindrical in shape and has slots on the upper and lower sides of the middle outer side. The transverse positioning tube 1 includes transverse telescopic rods 101 slidably installed on the inner sides of both ends. The outer ends of the transverse telescopic rods 101 are connected to the outer ends of longitudinal telescopic rods 103. The longitudinal telescopic rods 103 are cylindrical in shape and have limiting plates at their inner ends. The inner ends of the two longitudinal telescopic rods 103 are slidably installed on the inner sides of both ends of the longitudinal positioning tube 102. Cleaning positioning plates 104 are installed at both ends of the transverse positioning tube 1 and the longitudinal positioning tube 102. The cleaning positioning plates 104 are annular in shape, and their outer ends are connected to the inner ends of scrapers 105 via springs. The outer end of 105 is tapered, and a transverse telescopic rod 101 and a longitudinal telescopic rod 103 are slidably installed on the inner side of the scraper 105 and the cleaning positioning plate 104; a drive wheel 106 is installed on the top inner side of the cleaning positioning plate 104 through a bearing seat, wherein the outer side of the drive wheel 106 is distributed with inclined serrations; a rotating ring 107 is rotatably installed on the inner side of the cleaning positioning plate 104; the rotating ring 107 is annular, and the inner side of the rotating ring 107 is provided with inclined serrations and a brush, and the inclined serrations on the inner side of the rotating ring 107 are meshed and connected with the inclined serrations on the outer side of the drive wheel 106, and the inner side of the rotating ring 107 is provided with evenly distributed positioning grooves 108; the positioning grooves 108 are circular, and the inner side of the positioning grooves 108 is connected to the inner end of the movable cleaning plate 109 through a spring.The outer end of the movable cleaning plate 109 is inclined and slides on the outside of the transverse telescopic rod 101 and the longitudinal telescopic rod 103. During the reinforcement binding construction of the cantilever retaining wall, the positions of the transverse telescopic rod 101 and the longitudinal telescopic rod 103 are adjusted according to the contour of the cantilever retaining wall, so that the transverse telescopic rod 101 moves and extends inside the two ends of the transverse positioning tube 1, and the longitudinal telescopic rod 103 moves and extends inside the two ends of the longitudinal positioning tube 102 to match retaining walls of different sizes. After the reinforcement construction of the cantilever retaining wall is completed, the scraper 105 is pushed outward on the outside of the cleaning positioning plate 104, so that the conical structure on the outside of the scraper 105 cleans the concrete or other debris dripping from the outside of the transverse telescopic rod 101 and the longitudinal telescopic rod 103. Under the action of the spring, the scraper 105 returns to its original position. When the transverse telescopic rod 101 is slidably installed inside the transverse positioning tube 1, or the longitudinal telescopic rod 103 is slidably installed inside the longitudinal positioning tube 102, the outer side of the transverse telescopic rod 101 or the longitudinal telescopic rod 103 pushes the inclined sawtooth on the outer side of the drive wheel 106. The outer end of the inclined sawtooth is a rubber structure, causing the drive wheel 106 to drive the rotating ring 107 to rotate inside the cleaning positioning plate 104. Under the action of the spring, the movable cleaning plate 109 moves outward inside the positioning groove 108, so that the outer end of the movable cleaning plate 109 cleans the debris remaining on the transverse telescopic rod 101 or the longitudinal telescopic rod 103 again. The brush inside the rotating ring 107 ensures the cleanliness of the cleaning and prevents the debris remaining on the transverse telescopic rod 101 and the longitudinal telescopic rod 103 from affecting the smoothness of sliding in later use.

[0036] Example 2: This invention provides a cantilever retaining wall reinforcement positioning device, which further includes a marking plate 2 annularly installed on the outer side of a transverse positioning tube 1; the marking plate 2 has an arc-shaped structure, and the opening on the side of the marking plate 2 is slidably installed in the slots on the upper and lower sides of the middle position on the outer side of the transverse positioning tube 1, and the marking plate 2 has a guide groove 201 inside; the guide groove 201 has slots on both sides, and the slots on both sides of the guide groove 201 are located on both sides of the marking plate 2; a guide plate 202 is slidably installed inside the guide groove 201; the guide plate 202 has an arc-shaped structure, and the inner ends of the guide plate 202 have protrusions on both sides, and the protrusions on both sides of the inner ends of the guide plate 202 are slidably installed in the guide groove 201. The outer end of the guide plate 202 is slidably installed in the groove on the side, and the outer end of the guide plate 202 is slidably installed in the other end of the guide groove 201; the inner side of the marking plate 2 is provided with two positioning storage slots 203; among them, the inner side of the positioning storage slot 203 and the inner side of the guide plate 202 are connected by a spring to a fixing plate 204; the fixing plate 204 is an arc-shaped structure, and three fixing plates 204 are installed on the outer side of the transverse positioning tube 1 and the transverse telescopic rod 101; a protective cover 205 is installed at the middle position of the outer side of the marking plate 2; a rotating rod 206 is rotatably installed on the inner side of the protective cover 205, and the rotating rod 206 is a cylindrical structure; a fan blade 207 is provided on the outer side of the rotating rod 206; a reflector 208 is installed at the outer edge of the fan blade 207; The reflector 208 has arc-shaped ends, and a reflector mirror is installed on the outer side of the reflector 208. The reflector 208 is rotatably installed on the inner side of the protective cover 205. During the construction of the cantilever retaining wall reinforcement binding, the number of marking plates 2 is adjusted according to the distribution and quantity of the reinforcement on the retaining wall. A certain number of marking plates 2 are slidably installed on the transverse positioning tube 1 and the transverse telescopic rod 101 through the slot in the middle of the outer side of the transverse positioning tube 1. The marking plates 2 are evenly distributed on the transverse positioning tube 1 and the transverse telescopic rod 101. The guide plate 202 moves outward inside the guide groove 201, and the guide plate 202 drives a fixed plate 204 to move outward, so that a fixed plate 204 moves outward. 4. The fixing plates 204 in the other two positioning storage tanks 203 are placed on the outside of the horizontal positioning tube 1 and the horizontal telescopic rod 101. Under the action of the spring, the three fixing plates 204 are fixedly installed on the horizontal positioning tube 1 and the horizontal telescopic rod 101, so that the marking plates 2 are evenly distributed to position the steel bars, which facilitates the reasonable distribution of steel bars for binding construction and ensures that the strength of each part of the retaining wall is evenly distributed. At the same time, the airflow in the air drives the fan blades 207 on the outside of the rotating rod 206 inside the protective cover 205 to rotate, which drives the reflector 208 to rotate, and the reflector on the outside of the reflector 208 reflects the light, which makes it easier for construction personnel to observe the position of the steel bar markings more intuitively.

[0037] Example 3: This invention provides a cantilever retaining wall reinforcement positioning device, which further includes a positioning clamp 3 and a fixing clamp 301 installed on the outer side of a transverse positioning tube 1 and a transverse telescopic rod 101; the inner side of the positioning clamp 3 and the inner side of the fixing clamp 301 are arc-shaped structures, and the two ends of the arc-shaped structure on the inner side of the positioning clamp 3 are inserted into the two ends of the arc-shaped structure on the inner side of the fixing clamp 301, and the positioning clamp 3 and the fixing clamp 301 are fixedly connected by fixing bolts; a guide rod 302 is installed at the middle position on the outer side of the positioning clamp 3; the outer side of the guide rod 302 is threaded, and a rotating part 303 is rotatably installed at the outer end of the guide rod 302; the edge of the rotating part 303 is inclined; A positioning sleeve 304 is rotatably installed on the outer side of the rod 302; the positioning sleeve 304 has a ring structure and is also rotatably installed on the outer side of the rotating part 303; a left clamping plate 305 is installed on the side end of the rotating part 303; the inner side of the left clamping plate 305 has an arc-shaped structure, and a right clamping plate 306 is installed on the inner side of the left clamping plate 305 by fixing bolts; the bottom of the wall positioning tube 307, the wall-mounted positioning tube 308, and the plinth positioning tube 309 are respectively installed on the inner sides of the three left clamping plates 305 and right clamping plates 306; the wall positioning tube 307, the wall-mounted positioning tube 308, and the plinth positioning tube 309 have a round tube structure; the top of the wall-mounted positioning tube 308 is installed on the positioning clamping plate 3 and the fixing clamp. Between plates 301; the top of the plinth positioning tube 309 is installed between the left clamping plate 305 and the right clamping plate 306. During the construction of the cantilever retaining wall reinforcement binding, the positioning clamping plate 3 and the fixing clamping plate 301 are installed at appropriate positions on the transverse positioning tube 1 and the transverse telescopic rod 101. By using fixing bolts, the three positioning clamping plates 3 and the fixing clamping plate 301 are installed on the transverse positioning tube 1 and the transverse telescopic rod 101. Then, the three left clamping plates 305 and the right clamping plate 306 fix the bottom of the wall positioning tube 307, the wall support positioning tube 308, and the plinth positioning tube 309 in sequence. Rotating the rotating part 303 at the outer end of the guide rod 302 will drive the left clamping plate 305 and the wall support positioning tube 308 to rotate. The bottom of the wall positioning tube 307, the wall backup positioning tube 308, and the plinth positioning tube 309, which are fixed by the right clamp 306, are at a suitable angle. The positioning sleeve 304 is rotated outside the guide rod 302, so that one end of the positioning sleeve 304 presses against the rotating part 303 and fixes it. This allows the wall positioning tube 307 and the wall backup positioning tube 308 to position the steel bars on the wall surface and back of the retaining wall, respectively. The top of the plinth positioning tube 309 is fixed above the wall backup positioning tube 308 by another left clamp 305 and right clamp 306, so that the plinth positioning tube 309 positions the steel bars at the plinth position of the retaining wall. The operation is relatively convenient, the positioning deviation is small, and it plays a significant role in inspection and acceptance.

[0038] The specific usage and function of this embodiment: In this invention, during use, the lengths of the transverse telescopic rod 101 and the longitudinal telescopic rod 103 are adjusted according to the contour of the cantilever retaining wall. The transverse telescopic rod 101 moves telescopically inside both ends of the transverse positioning tube 1, and the longitudinal telescopic rod 103 moves telescopically inside both ends of the longitudinal positioning tube 102. Then, the number of marking plates 2 is adjusted according to the distribution of the reinforcing bars on the retaining wall. A certain number of marking plates 2 are slidably installed on the transverse positioning tube 1 and the transverse telescopic rod 101 through the slot in the middle of the outer side of the transverse positioning tube 1.

Under the action of the spring, the three fixed plates 204 are fixedly installed. Marking plates 2 are evenly distributed on the horizontal positioning tube 1 and the horizontal telescopic rod 101 to position the reinforcing bars. The airflow in the air drives the fan blades 207 on the outside of the rotating rod 206 to rotate. The fan blades 207 drive the reflector on the outside of the reflector 208 to reflect light. The construction personnel can directly observe the position of the reinforcing bar markings. The positioning clamps 3 and the fixing clamps 301 are installed in appropriate positions on the horizontal positioning tube 1 and the horizontal telescopic rod 101. The three left clamps 305 and right clamps 306 fix the bottom of the wall positioning tube 307, the wall backup positioning tube 308, and the plinth positioning tube 309 in sequence. The wall positioning tube 307 and the wall backup positioning tube 308 position the reinforcing bars on the wall surface and the back of the retaining wall, respectively. The plinth positioning tube 309 positions the reinforcing bars at the plinth position of the retaining wall.

[0039] After the reinforcement construction of the cantilever retaining wall is completed, the scraper 105 is pushed outward to clean the concrete or other debris dripping from the outside of the transverse telescopic rod 101 and the longitudinal telescopic rod 103. When the transverse telescopic rod 101 or the longitudinal telescopic rod 103 moves, it drives the drive wheel 106 to drive the rotating ring 107 to rotate. The rotating ring 107 drives the outer end of the movable cleaning plate 109 to clean the debris remaining on the transverse telescopic rod 101 or the longitudinal telescopic rod 103 again, so that the transverse telescopic rod 101 and the longitudinal telescopic rod 103 can move smoothly.
