Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a steel cage protective layer pad. Background Technology

[0002] Reinforced concrete structures possess strong compressive and seismic resistance, and are widely used in various construction projects. In reinforced concrete structures, the concrete cover is the first barrier preventing external corrosive media such as moisture, oxygen, and chloride ions from contacting the reinforcing bars. Its thickness must be strictly designed according to specifications to avoid affecting the durability of the reinforced concrete structure due to insufficient concrete cover thickness. In actual construction, the reinforcing bars are first tied into a reinforcing cage according to the structural design drawings. Then, concrete cover spacers are placed between the inner wall of the formwork and the outer wall of the reinforcing cage. These spacers support the reinforcing cage and ensure that the reinforcing bars have a sufficiently thick protective layer.

[0003] In existing technologies, concrete spacers are commonly used as spacers for the protective layer of reinforcing cages. When installing concrete spacers, supporting reinforcing bars for the spacers need to be welded to the reinforcing cage. Using this type of concrete spacer as the protective layer not only increases construction costs but also makes installation more cumbersome, increases the workload of workers, reduces work efficiency, and can easily affect the construction schedule. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A reinforcement cage protective layer spacer is provided, comprising:

[0007] The pad block body has interconnected through channels and locking slots. The locking slots are located at the centroid of the pad block body and extend through the pad block body along its thickness direction. The locking slots are configured to lock the reinforcing bars so that the reinforcing bars are perpendicular to the pad block body. The through channels extend radially along the pad block body. Limiting slots are provided on the two side walls of the through channels near the locking slot.

[0008] The clamping member is detachably inserted into the through-channel along the axial direction of the pad body, and both ends of the clamping member are respectively locked in the two limiting slots. The side of the clamping member facing the locking slot abuts against the reinforcing bar along the radial direction of the reinforcing bar.

[0009] Optionally, the clamping member includes an abutment boss, a clamping part, two snap-fit ​​parts, and a connecting part. The clamping part, the connecting part, and the two snap-fit ​​parts are all perpendicularly connected to the abutment boss. The two snap-fit ​​parts are located at opposite ends of the abutment boss. The clamping part is located on the side of the abutment boss facing the snap-fit ​​groove and between the two snap-fit ​​parts. The clamping part and the two snap-fit ​​parts are spaced apart. The connecting part is connected to the side of the two snap-fit ​​parts away from the clamping part. The two snap-fit ​​parts have a pressing state where they are close to each other and a clamping state where they are respectively snapped into the two limiting slots. In the clamping state, the clamping part is inserted into the through-channel and abuts against the reinforcing bar along the radial direction of the reinforcing bar. The abutment boss abuts against the pad body.

[0010] Optionally, the end of the snap-fit ​​portion opposite to the abutment boss is provided with a hook protrusion, and in the clamping state, the hook protrusion is hooked onto the side of the pad body opposite to the abutment boss.

[0011] Optionally, a guide slope is provided on the side of the hook protrusion facing the inner wall of the limiting slot, and the guide slope gradually approaches the clamping part along the direction from the abutment boss to the hook protrusion.

[0013] Optionally, the clamping part has an arc-shaped clamping surface on the side facing the locking groove, and the arc-shaped clamping surface can wrap around the reinforcing bar so that the clamping part clamps the outer wall of the reinforcing bar.

[0014] Optionally, an anti-slip structure is provided on the arc-shaped clamping surface, and the reinforcing bar makes frictional contact with the arc-shaped clamping surface through the anti-slip structure.

[0015] Optionally, the anti-slip structure includes diamond-shaped protrusions.

[0018] The beneficial effects of this utility model are:

[0019] This utility model provides a reinforcing cage protective layer spacer, including a spacer body and a clamping member. When installing the reinforcing cage protective layer spacer, first align the outer end of the through-channel of the spacer body with the transverse reinforcing bars of the reinforcing cage, then move the spacer body so that the transverse reinforcing bars pass through the through-channel and are clamped in the clamping groove. At this time, the transverse reinforcing bars are perpendicular to the spacer body. Then, insert the clamping member into the through-channel and clamp both ends of the clamping member into the two limiting grooves, so that the clamping member abuts against the reinforcing bar along the radial direction of the reinforcing bar, thereby enabling the clamping member to clamp and fix the reinforcing bar. By setting up interconnected through-holes and locking slots, the transverse reinforcing bars of the rebar cage can be passed through and locked onto the pad block body. Then, the clamping member is inserted into the through-hole and its two ends are locked into the two limiting slots, so that the clamping member can abut against the reinforcing bar radially, thereby clamping and fixing the reinforcing bar, realizing the installation of the rebar cage protective layer pad block. The installation method is simple and convenient. Moreover, using this rebar cage protective pad block eliminates the need for additional welding of supporting reinforcing bars, which can reduce construction costs and the workload of workers, improve work efficiency, and avoid affecting the construction cycle.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] This embodiment provides a reinforcing cage protective layer spacer, such as... Figures 1 to 3 As shown, the installation method of the steel cage protective layer spacer is simple and convenient, which can reduce construction costs and the workload of workers, improve work efficiency, and avoid affecting the construction cycle.

[0032] like Figures 1 to 3As shown, the reinforcing cage protective layer spacer includes a spacer body 1 and a clamping member 2. The spacer body 1 has interconnected through-hole channels 11 and locking grooves 12. The locking groove 12 is located at the centroid of the spacer body 1 and extends through the spacer body 1 along its thickness direction. The locking groove 12 is configured to clamp the reinforcing bars so that the reinforcing bars are perpendicular to the spacer body 1. The through-hole channels 11 extend radially along the spacer body 1, and each of the two sidewalls of the through-hole channels 11 near the locking groove 12 is provided with a limiting groove 13. The clamping member 2 is detachably inserted into the through-hole channels 11 along the axial direction of the spacer body 1, and both ends of the clamping member 2 are respectively clamped in the two limiting grooves 13. The side of the clamping member 2 facing the locking groove 12 abuts against the reinforcing bar radially, thereby clamping and fixing the reinforcing bar.

[0033] The reinforcing cage 100 includes longitudinal reinforcing bars 1001 and transverse reinforcing bars 1002 arranged circumferentially around the outer side of the longitudinal reinforcing bars 1001. When installing the reinforcing cage protective layer spacer, first align the outer end of the through-channel 11 of the spacer body 1 with the transverse reinforcing bars 1002 of the reinforcing cage 100. Then move the spacer body 1 so that the transverse reinforcing bars 1002 pass through the through-channel 11 and are locked in the locking groove 12. At this time, the transverse reinforcing bars 1002 are perpendicular to the spacer body 1. Then insert the clamping member 2 into the through-channel 11 and lock both ends of the clamping member 2 into the two limiting grooves 13 respectively, so that the clamping member 2 abuts against the reinforcing bar along the radial direction of the reinforcing bar, thereby enabling the clamping member 2 to clamp and fix the reinforcing bar. By setting up interconnected insertion channels 11 and locking slots 12, the transverse reinforcing bars 1002 of the reinforcing cage 100 can be inserted and locked onto the pad body 1. Then, the clamping member 2 is inserted into the insertion channel 11 and its two ends are locked into the two limiting slots 13, so that the clamping member 2 can abut against the reinforcing bar radially, thereby clamping and fixing the reinforcing bar, realizing the installation of the reinforcing cage protective layer pad. The installation method is simple and convenient. Moreover, using the reinforcing cage protective pad does not require additional welding of supporting reinforcing bars, which can reduce construction costs and the workload of workers, improve work efficiency, and avoid affecting the construction cycle.

[0034] It should be noted that the shape of the pad block body 1 is the same as that of the steel cage 100, and the distance from the centroid of the pad block body 1 to the edge of the pad block body 1 is the required protective layer thickness of the steel cage 100.

[0035] For example, if the steel cage 100 is cylindrical, then the pad block body 1 is cylindrical.

[0036] In this embodiment, the pad body 1 is a concrete pad body 1. In other embodiments, other materials may be selected to make the pad body 1 according to actual needs, and no limitation is made here.

[0037] Optionally, such as Figure 1 and Figure 2 As shown, the clamping member 2 includes an abutment boss 21, a clamping part 22, two snap-fit ​​parts 23, and a connecting part 24. The clamping part 22, the connecting part 24, and the two snap-fit ​​parts 23 are all perpendicularly connected to the abutment boss 21, with the two snap-fit ​​parts 23 located at opposite ends of the abutment boss 21. The clamping part 22 is located on the side of the abutment boss 21 facing the snap-fit ​​groove 12 and is situated between the two snap-fit ​​parts 23. The clamping part 22 and the two snap-fit ​​parts 23 are spaced apart, and the connecting part 24 is connected to the side of the two snap-fit ​​parts 23 opposite to the clamping part 22. The two snap-fit ​​parts 23 have a pressing state where they are close to each other and a clamping state where they are respectively snapped into the two limiting slots 13. In the clamping state, the clamping part 22 is inserted into the through-channel 11, and the clamping part 22 abuts against the reinforcing bar radially, while the abutment boss 21 abuts against the pad body 1.

[0038] When the clamping part 2 needs to be inserted, the two locking parts 23 are pressed towards each other, so that the two locking parts 23 are close to each other and the distance between the two locking parts 23 is reduced. At this time, the two locking parts 23 are in a compressed state. Then, the two locking parts 23 are aligned with the two limiting slots 13 and inserted into the through channel 11 along the thickness direction of the pad body 1 until the abutting boss 21 abuts against the pad body 1. At this time, the two locking parts 23 are respectively opened in the two limiting slots 13, that is, the locking parts 23 are in a clamping state. The clamping part 22 is inserted into the through channel 11 and abuts against the steel bar along the radial direction of the steel bar, thereby realizing the clamping and fixing of the steel bar by the clamping part 22. The structure is simple and the operation is convenient.

[0039] Optionally, such as Figure 1 and Figure 2 As shown, a hook protrusion 25 is provided at the end of the snap-fit ​​part 23 opposite to the abutment boss 21. In the clamping state, the hook protrusion 25 hooks onto the side of the pad body 1 opposite to the abutment boss 21. By providing the hook protrusion 25, the snap-fit ​​strength between the clamping member 2 and the pad body 1 can be strengthened, thereby strengthening the fixing strength of the clamping member 2 to the reinforcing bar, making the overall structure stable, preventing the pad body 1 from shifting, ensuring the accuracy of the protective layer thickness of the reinforcing cage 100, and thus ensuring the mechanical properties of the reinforced concrete structure.

[0040] Optionally, such as Figure 1 and Figure 2As shown, a guide slope 251 is provided on the side of the hook protrusion 25 facing the inner wall of the limiting slot 13. The guide slope 251 gradually approaches the clamping part 22 along the direction from the abutment boss 21 to the hook protrusion 25. When installing the reinforcing cage protective layer pad, the clamping part 22 needs to be inserted into the through channel 11, and the two locking parts 23 need to be pressed together. The hook protrusion 25 is then aligned with the limiting slot 13 and inserted into the limiting slot 13. By providing the guide slope 251 on the hook protrusion 25, the hook protrusion 25 and the locking parts 23 can be guided into the limiting slot 13, providing a guiding function and facilitating the insertion and installation of the clamping part 2.

[0041] In this embodiment, the clamping member 2 also includes a support portion. One end of the support portion is connected to the side of the clamping member 22 opposite to the locking groove 12, and the other end is connected to the connecting portion 24. By providing the support portion, the radial clamping strength of the clamping member 22 on the reinforcing bar can be strengthened, ensuring the installation stability of the pad block body 1.

[0042] Optionally, such as Figure 1 and Figure 2 As shown, the clamping part 22 has an arc-shaped clamping surface 221 on the side facing the locking groove 12. The arc-shaped clamping surface 221 can wrap around the reinforcing bar so that the clamping part 22 clamps the outer wall of the reinforcing bar. By providing the arc-shaped clamping surface 221, the clamping part 22 can wrap around the outer wall of the reinforcing bar, so that the two are in close contact, thereby enabling the clamping member 2 to clamp and fix the reinforcing bar along the circumference of the reinforcing bar, improving the fixing effect of the clamping member 2 on the reinforcing bar, and ensuring the installation stability of the pad block body 1.

[0043] It should be noted that the clamping part 2 is made of relatively hard plastic and is molded as a single piece.

[0044] Optionally, an anti-slip structure is provided on the arc-shaped clamping surface 221. The reinforcing bar comes into frictional contact with the arc-shaped clamping surface 221 through the anti-slip structure to increase the friction force. This can effectively prevent loosening caused by the smooth surface of the clamping part 22 in contact with the reinforcing bar, thereby avoiding displacement of the pad body 1 and ensuring the accuracy of the protective layer thickness of the reinforcing bar cage 100.

[0045] Optionally, multiple raised patterns can be provided on the arc-shaped clamping surface 221 as an anti-slip structure. The patterns are arranged in a matrix to cover the entire arc-shaped clamping surface 221. The patterns can be strip-shaped, rhomboid, hemispherical, etc., and appropriate patterns can be selected according to actual needs. There is no limitation here. In this embodiment, rhomboid protrusions are selected as the anti-slip structure.

[0046] In this embodiment, the reinforcing cage protective layer pad also includes an anti-slip layer. The anti-slip layer is affixed to the inner wall of the locking groove 12 and extends circumferentially along the locking groove 12. By providing the anti-slip layer, the friction between the reinforcing bar and the pad body 1 can be enhanced, preventing the pad body 1 from shifting, and further ensuring the accuracy of the protective layer thickness of the reinforcing cage 100.

[0047] For example, the anti-slip layer includes a rubber anti-slip layer.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
