Description

Technical Field

[0001] This utility model relates to the field of exposed steel bar protection technology, and in particular to a device for quickly and evenly coating steel bars with cement slurry. Background Technology

[0002] In the field of engineering construction, work stoppages or pauses often occur during reinforced concrete construction due to various reasons such as work sequence arrangements and uncontrollable factors during construction. This can result in prolonged exposure of the reinforcing steel bars in the already constructed reinforced concrete. Long-term exposure of the reinforcing steel bars requires protective coating with cement slurry to safeguard the surface of the exposed portions. Since reinforcing steel bars exposed to air for extended periods are susceptible to corrosion from rain, snow, and water vapor, it is essential to apply cement slurry to prevent rust.

[0003] Currently, cement slurry is applied to the surface of exposed rebar by using a coating sleeve attached to the rebar. However, the cement slurry coating device is not easy to quickly and stably engage when it is attached to the rebar, and the engagement is unstable, which can easily cause the cement slurry coating device to separate. This affects the uniform application of cement slurry to the surface of exposed rebar. In addition, the cement slurry is relatively thin and tends to flow rapidly inside the coating device and drip outwards, making it difficult to maintain sufficient and uniform application of cement slurry to exposed rebar.

[0004] Therefore, a device for quickly and evenly coating steel bars with cement slurry is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the shortcomings of existing cement slurry application devices, which are not easy to quickly and stably engage when the opening and closing sleeve is connected to the reinforcing bar, and the engagement is unstable, which easily leads to the cement slurry application device separating and affects the uniform application of cement slurry to the exposed reinforcing bar surface. Therefore, this invention proposes a device that enables the reinforcing bar to be quickly and uniformly coated with cement slurry.

[0006] To achieve the above objectives, this utility model provides the following technical solution: Design a device for quickly and evenly coating steel bars with cement slurry, including a sheet metal tube, the sheet metal tube having a structure of two semi-circular tubes, a hinge mechanism connected to one side of its surface, a snap-fit ​​mechanism installed on the other side of its surface, and a sponge sleeve fitted on the inner surface of the sheet metal tube. The hinge mechanism includes a first hinge post, a first hinge sleeve is fitted onto the surface of the first hinge post, and the outer side of the first hinge sleeve is fixedly connected to the side of the sheet metal tube. The buckling mechanism includes a buckling plate, a first connecting plate is fixed to one side of the snap-fit ​​part of the sheet metal tube, a second connecting plate is fixed to the other side of the snap-fit ​​part of the sheet metal tube, the buckling plate is hinged to the outside of the first connecting plate, and the outer end of the buckling plate is snapped to the outside of the second connecting plate.

[0007] Furthermore, the first hinge column gap is vertically installed at the movable hinge on the side of the sheet metal tube, and two adjacent first hinge sleeves are respectively connected to both sides of the movable hinge of the sheet metal tube.

[0008] Furthermore, both the first connecting plate and the second connecting plate are rectangular plate structures, both are vertically arranged, and the gaps between them are parallel. A second hinge post is installed between the first connecting plate and the buckle plate.

[0009] Furthermore, a second hinge sleeve is fixed to the outer side of the first connecting plate, and a third hinge sleeve is fixed to one side of the second connecting plate. Both the third hinge sleeve and the second hinge sleeve are rotatably sleeved on the surface of the second hinge post.

[0010] Furthermore, the third hinge sleeve is slidably overlapped on the top of the second hinge sleeve, and the buckle plate is hingedly connected to the first connecting plate through the third hinge sleeve, the second hinge post, and the second hinge sleeve.

[0011] Furthermore, the buckle plate has an L-shaped structure and is horizontally snapped onto the outside of the second connecting plate. The outer end of the buckle plate, located on the outside of the second connecting plate, has a snap-fit ​​hole. The surface of the second connecting plate has a guide hole, and the guide hole and the snap-fit ​​hole are horizontally aligned.

[0012] Furthermore, a snap-fit ​​rod slides through the inside of the guide hole, a limit plate is fixed at the inner end of the snap-fit ​​rod located between the first connecting plate and the second connecting plate, a limit ring is fixed on the surface of the snap-fit ​​rod located inside the snap-fit ​​hole, a spring is sleeved on the surface of the snap-fit ​​rod located between the limit ring and the guide hole, and the outer end of the snap-fit ​​rod snaps through the snap-fit ​​hole.

[0013] Furthermore, handles are evenly fixed on both sides of the sheet metal tube, a flow guide ring is fixed at the top of the sheet metal tube, the flow guide ring has a funnel-shaped structure, a snap-fit ​​strip is fixed on the inner surface of the sheet metal tube, a snap-fit ​​groove is opened on the outer surface of the sponge sleeve, the snap-fit ​​strip is slidably inserted into the snap-fit ​​groove, both the snap-fit ​​groove and the snap-fit ​​strip have a spiral structure, and the depth of the snap-fit ​​groove is less than the thickness of the sponge sleeve.

[0014] Compared with the prior art, the device for quickly and evenly coating steel bars with cement slurry proposed in this utility model has the following advantages: 1. This utility model features a rotating opening and closing mechanism on one side of a sheet metal tube via a first hinge sleeve and a first hinge column. Furthermore, a snap-fit ​​mechanism connects two semi-circular sheet metal tubes. During construction, the sheet metal tube is used to wrap the reinforcing steel. The snap-fit ​​plate is rotated via the second hinge column and third hinge sleeve, causing it to snap onto the outside of the second connecting plate. Simultaneously, a spring moves the snap-fit ​​rod and the limiting ring outwards, inserting the outer end of the snap-fit ​​rod into the snap-fit ​​hole, while the limiting ring abuts against the inner side of the snap-fit ​​plate. This allows for quick and stable snap-fit ​​of the sheet metal tube, preventing it from easily loosening. Cement slurry is then added into the sheet metal tube along the guide ring to reduce spillage. Finally, by sliding the handle upwards on the sheet metal tube, cement slurry can be quickly applied to the exposed reinforcing steel surface.

[0015] 2. This utility model fixes a spiral-shaped snap-fit ​​strip on the surface of the iron pipe. Therefore, the sponge sleeve is snapped and connected to the snap-fit ​​strip through the spiral snap-fit ​​groove, thereby keeping the sponge sleeve stably installed on the inner surface of the iron pipe. When the iron pipe moves upward and cement slurry is applied to the exposed steel bars, the sponge sleeve remains stably fitted on the inner surface of the iron pipe, preventing accumulation and wrinkles, and facilitating disassembly and replacement of the sponge sleeve. Therefore, the sponge sleeve adheres to and absorbs the cement slurry, and as the iron pipe moves upward, cement slurry can be evenly applied to the surface of the exposed steel bars, avoiding cement slurry dripping and being wasted.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] For examples, please refer to Figures 1 to 8 The device shown in the figure for quickly and evenly coating steel bars with cement slurry includes a sheet metal tube 1, which is a two-semi-circular tube structure. One side of its surface is connected to a hinge mechanism, and the other side of its surface is installed with a snap-fit ​​mechanism. A sponge sleeve 4 is fitted onto the inner surface of the sheet metal tube 1.

[0020] In detail, the hinge mechanism includes a first hinge post 6, a first hinge sleeve 16 is sleeved on the surface of the first hinge post 6, and the outer side of the first hinge sleeve 16 is fixedly connected to the side of the sheet metal tube 1.

[0021] The first hinge post 6 is vertically installed at the movable hinge point on the side of the sheet metal tube 1, and two adjacent first hinge sleeves 16 are respectively connected to the two sides of the movable hinge point of the sheet metal tube 1.

[0022] Furthermore, the buckling mechanism includes a buckling plate 3, a first connecting plate 9 is fixed on one side of the buckling part of the sheet metal tube 1, and a second connecting plate 13 is fixed on the other side of the buckling part of the sheet metal tube 1. The buckling plate 3 is hinged to the outside of the first connecting plate 9, and the outer end of the buckling plate 3 is buckled to the outside of the second connecting plate 13.

[0023] The first connecting plate 9 and the second connecting plate 13 are both rectangular plate structures, both vertically arranged, and the gaps between them are parallel. A second hinge post 10 is installed between the first connecting plate 9 and the buckle plate 3.

[0024] A second hinge sleeve 12 is fixed to the outer side of the first connecting plate 9, and a third hinge sleeve 11 is fixed to one side of the second connecting plate 13. Both the third hinge sleeve 11 and the second hinge sleeve 12 are rotatably sleeved on the surface of the second hinge post 10.

[0025] The third hinge sleeve 11 is slidably overlapped at the top of the second hinge sleeve 12, and the buckle plate 3 is hingedly connected to the first connecting plate 9 through the third hinge sleeve 11, the second hinge post 10, and the second hinge sleeve 12.

[0026] The steel pipe 1 is opened and closed by rotating through the first hinge sleeve 16 and the first hinge column 6 on one side. Moreover, the two semi-circular steel pipes 1 are connected by a snap-fit ​​mechanism. Therefore, during construction, the steel bar is wrapped with the steel pipe 1, and the snap-fit ​​plate 3 is rotated through the second hinge column 10 and the third hinge sleeve 11 so that the snap-fit ​​plate 3 is snapped onto the outside of the second connecting plate 13.

[0027] Furthermore, the buckle plate 3 has an L-shaped structure and is horizontally snapped onto the outside of the second connecting plate 13. The outer end of the buckle plate 3, located on the outside of the second connecting plate 13, has a snap-fit ​​hole 20. The surface of the second connecting plate 13 has a guide hole 17, which is horizontally aligned with the snap-fit ​​hole 20.

[0028] A snap-fit ​​rod 15 slides through the inside of the guide hole 17. A limit plate 14 is fixed at the inner end of the snap-fit ​​rod 15, located between the first connecting plate 9 and the second connecting plate 13. A limit ring 19 is fixed on the surface of the snap-fit ​​rod 15, located inside the snap-fit ​​hole 20. A spring 18 is sleeved on the surface of the snap-fit ​​rod 15, located between the limit ring 19 and the guide hole 17. The outer end of the snap-fit ​​rod 15 snaps through the snap-fit ​​hole 20.

[0029] Spring 18 moves the locking rod 15 and the limiting ring 19 outward, so that the outer end of the locking rod 15 is inserted into the locking hole 20, and the limiting ring 19 abuts against the inner side of the buckle plate 3. Therefore, the sheet metal tube 1 can be quickly locked and the sheet metal tube 1 can be kept locked stably and not easily loosened.

[0030] Handles 2 are evenly fixed on both sides of the sheet metal tube 1, and a flow guide ring 5 is fixed at the top of the sheet metal tube 1. The flow guide ring 5 has a funnel-shaped structure.

[0031] Add cement slurry into the inside of the sheet metal pipe 1 along the guide ring 5 to reduce cement slurry spillage, and quickly apply cement slurry to the surface of the exposed steel bars by sliding the sheet metal pipe 1 upward by the handle 2.

[0032] Finally, the inner surface of the sheet metal pipe 1 is fixed with a snap-fit ​​strip 8, and the outer surface of the sponge sleeve 4 is provided with a snap-fit ​​groove 7. The snap-fit ​​strip 8 slides into the snap-fit ​​groove 7. Both the snap-fit ​​groove 7 and the snap-fit ​​strip 8 are spiral structures, and the depth of the snap-fit ​​groove 7 is less than the thickness of the sponge sleeve 4.

[0033] The sponge sleeve 4 is connected to the snap-fit ​​strip 8 through the spiral snap-fit ​​groove 7, thereby keeping the sponge sleeve 4 stably installed on the inner surface of the iron pipe 1. When the iron pipe 1 moves upward and applies cement slurry to the exposed steel bars, the sponge sleeve 4 is kept stably fitted on the inner surface of the iron pipe 1, which is not easy to accumulate or wrinkle, and is easy to disassemble and replace. Therefore, the sponge sleeve 4 adheres and absorbs the cement slurry. As the iron pipe 1 moves upward, the cement slurry can be evenly applied to the surface of the exposed steel bars, avoiding the cement slurry from dripping outward and being wasted.

[0034] Working method: The iron pipe 1 is opened and closed by rotating the first hinge sleeve 16 and the first hinge column 6 on one side. The two semi-circular iron pipes 1 are connected by a snap-fit ​​mechanism. Therefore, during construction, the iron pipe 1 is wrapped with the steel bar. The snap-fit ​​plate 3 is rotated by the second hinge column 10 and the third hinge sleeve 11 so that the snap-fit ​​plate 3 is snapped on the outside of the second connecting plate 13. At the same time, the spring 18 pushes the snap-fit ​​rod 15 and the limiting ring 19 to move outward, so that the outer end of the snap-fit ​​rod 15 is inserted into the snap-fit ​​hole 20 and the limiting ring 19 abuts against the inside of the snap-fit ​​plate 3. Therefore, the iron pipe 1 can be snapped quickly and the iron pipe 1 is kept in a stable snap-fit ​​position and is not easy to loosen. Then, cement slurry is added into the iron pipe 1 along the guide ring 5 to reduce the spillage of cement slurry. By sliding the iron pipe 1 upward by the handle 2, cement slurry can be quickly applied to the surface of the exposed steel bar.

[0035] A spiral-shaped snap-fit ​​strip 8 is fixed to the surface of the sheet metal pipe 1. Therefore, the sponge sleeve 4 is snapped together with the snap-fit ​​strip 8 through the spiral-shaped snap-fit ​​groove 7, thereby keeping the sponge sleeve 4 stably installed on the inner surface of the sheet metal pipe 1. When the sheet metal pipe 1 moves upward and cement slurry is applied to the exposed steel bars, the sponge sleeve 4 is kept stably fitted on the inner surface of the sheet metal pipe 1, which is not easy to accumulate or wrinkle, and is easy to disassemble and replace. Therefore, the sponge sleeve 4 adheres to and absorbs the cement slurry. As the sheet metal pipe 1 moves upward, the cement slurry can be evenly applied to the surface of the exposed steel bars, avoiding the cement slurry from dripping outward and being wasted.

[0036] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
