Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a novel tie-free protective layer pad. Background Technology

[0002] Spacers are components commonly used in reinforced concrete structures, placed between reinforcing bars and formwork, to increase the lap area between the reinforcing bars and formwork, thereby increasing the bearing area between the reinforcing bars and formwork and solving localized bearing problems.

[0003] With the significant increase in the density of the stirrups in the pier columns, the previously effective disc-shaped concrete pads could no longer be installed. Other types of pads were prone to displacement and failure during the formwork installation process, and they required manual binding to the reinforcing bars. However, using the binding method to fix the concrete pads to the reinforcing bars was not only cumbersome, but also prone to the concrete pads falling off due to insecure binding, which affected work efficiency. Utility Model Content

[0004] To reduce the adverse impact of installation pads on work efficiency, this application provides a novel binding-free protective layer pad.

[0005] The novel non-binding protective layer pad provided in this application adopts the following technical solution: A novel non-binding protective layer pad includes an abutment portion. One end of the abutment portion along its length is fixedly connected to a connecting plate perpendicular to the length direction of the abutment portion. The connecting plate has a plurality of first snap-fit ​​portions on the side away from the abutment portion. Each of the first snap-fit ​​portions has a snap-fit ​​groove on the side away from the connecting plate, which is far from the connecting plate and is used to snap-fit ​​the reinforcing bar.

[0006] By adopting the above technical solution, the snap-fit ​​groove of the first snap-fit ​​part is oriented towards the reinforcing bar and snapped onto the reinforcing bar. At this time, the reinforcing bar is located in the snap-fit ​​groove and the abutment part is oriented towards the template side. This facilitates snapping the reinforcing bar while ensuring the thickness of the concrete pouring outside the reinforcing bar mesh, reducing the possibility of reinforcing bar leakage and reducing the adverse impact of the installation spacer on work efficiency.

[0007] Optionally, the snap-fit ​​groove is configured as a semi-circle adapted to the reinforcing bar.

[0008] By adopting the above technical solution, the semi-circular snap-fit ​​groove ensures that when the reinforcing bar is inserted into the snap-fit ​​groove, the side wall of the snap-fit ​​groove fits closely with the reinforcing bar, improving the stability of the snap-fit ​​between the reinforcing bar and the first snap-fit ​​part, and further reducing the adverse impact of the installation pad on work efficiency.

[0009] Optionally, the connecting plate, the abutting part, and the first snap-fit ​​part are integrally formed.

[0010] By adopting the above technical solution, the connecting plate, the abutting part, and the first snap-fit ​​part are integrally set, so that when the pad is subjected to external force, the connecting plate, the abutting part, and the first snap-fit ​​part are not easy to separate under the action of external force, thereby improving the stability of the pad installation.

[0011] Optionally, the first snap-fit ​​part is provided with a sliding plate located at the opening of the snap-fit ​​groove for tying the reinforcing bar. The sliding plate is configured as an arc shape that is concave from both ends to the middle away from the connecting plate. One end of the sliding plate is inserted into the first snap-fit ​​part and slidably connected to the first snap-fit ​​part. A first spring is fixedly connected to one end of the first snap-fit ​​part and the sliding plate inserted into the first snap-fit ​​part. When the sliding plate snaps the first snap-fit ​​part onto the reinforcing bar, the sliding plate and the inner sidewall of the snap-fit ​​groove form a ring that adapts to the cross-section of the reinforcing bar.

[0012] By adopting the above technical solution, the sliding plate is fully inserted into the first snap-fit ​​part, the first spring is compressed, and the first snap-fit ​​part is moved closer to the rebar until the rebar is snapped into the snap-fit ​​groove. The first spring recovers its deformation and pushes the sliding plate to slide away from the inside of the first snap-fit ​​part until it is spliced ​​with the inner wall of the snap-fit ​​groove to form a ring. At this time, the rebar is sealed in the snap-fit ​​groove by the sliding plate, thereby improving the stability of the rebar snap-fit ​​while reducing the adverse effects of the installation pad on work efficiency.

[0013] Optionally, the end of the sliding plate away from the first spring can be inserted into the first snap-fit ​​portion, and the end of the first snap-fit ​​portion away from the first spring is provided with a fixing member to fix the sliding plate.

[0014] By adopting the above technical solution, when the sliding plate and the inner wall of the snap-fit ​​groove are spliced ​​into a ring, the end of the sliding plate away from the first spring is inserted into the first snap-fit ​​part. At this time, the sliding plate and the first snap-fit ​​part are fixed by the fastener, which further improves the stability of the steel bar snap-fit.

[0015] Optionally, the fastener includes a snap-fit ​​block located in the first snap-fit ​​portion and slidably connected to the first snap-fit ​​portion. The first snap-fit ​​portion is provided with a second spring fixedly connected to the snap-fit ​​block. The sliding plate has a mounting groove adapted to the snap-fit ​​block at one end away from the first spring. The end of the snap-fit ​​block adapted to the mounting groove is configured as a side inclined towards the sliding plate and away from the first spring. When the end of the sliding plate away from the first spring is inserted into the first snap-fit ​​portion, the snap-fit ​​block is inserted into the mounting groove.

[0016] By adopting the above technical solution, the end of the sliding plate away from the first spring is inserted into the first locking part until it contacts the inclined surface of the locking block. At this time, the sliding plate continues to move and squeeze the locking block, and the second spring is compressed until the mounting groove is aligned with the locking block. At this time, the second spring restores its deformation and pushes the locking block to be inserted into the mounting groove, thereby improving the stability of the connection between the sliding plate and the first locking part.

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. With the snap-fit ​​groove of the snap-fit ​​part facing the reinforcing bar and snap-fit ​​onto the reinforcing bar, the reinforcing bar is snapped into the snap-fit ​​groove and the abutting part faces the formwork side. This makes it easy to snap-fit ​​the reinforcing bar while ensuring the thickness of the concrete pouring outside the reinforcing mesh, reducing the possibility of reinforcing bar exposure and reducing the adverse impact of the installation spacer on work efficiency. 2. The sliding plate is fully inserted into the first snap-fit ​​part, and the first spring is compressed. At this time, the first snap-fit ​​part is moved closer to the rebar until the rebar is snapped in the snap-fit ​​groove. The first spring restores its deformation and pushes the sliding plate to slide away from the inside of the first snap-fit ​​part until it is joined with the inner wall of the snap-fit ​​groove to form a ring. At this time, the rebar is sealed in the snap-fit ​​groove by the sliding plate, thereby improving the stability of the rebar snap-fit ​​while reducing the adverse effects of the installation pad on work efficiency. 3. The end of the sliding plate away from the first spring is inserted into the first locking part until it contacts the inclined surface of the locking block. At this time, the sliding plate continues to move and press the locking block, and the second spring is compressed until the mounting groove is aligned with the locking block. At this time, the second spring restores its deformation and pushes the locking block to be inserted into the mounting groove, thereby improving the stability of the connection between the sliding plate and the first locking part.

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] This application discloses a novel non-binding protective layer pad.

[0025] Example 1 Reference Figure 1 A novel non-binding protective layer pad includes an abutment portion 1 and a connecting plate 2 disposed at one end of the abutment portion 1 and perpendicular to the abutment portion 1. The middle part of one side of the connecting plate 2 is fixedly connected to the end of the abutment portion 1. The side of the connecting plate 2 away from the abutment portion 1 is provided with a plurality of first snap-fit ​​portions 3. In this embodiment, two portions are provided and symmetrically disposed at both ends of the connecting plate 2.

[0026] The first snap-fit ​​part 3 has a snap-fit ​​groove 31 on the side away from the connecting plate 2, which is away from the abutment part 1. The snap-fit ​​groove 31 is semi-circular. The abutment part 1, the connecting plate 2 and the first snap-fit ​​part 3 are integrally formed and are all made of polyethylene.

[0027] The implementation principle of Example 1 is as follows: the snap-fit ​​groove 31 of the first snap-fit ​​part 3 is oriented towards the reinforcing bar and snapped onto the reinforcing bar. At this time, the reinforcing bar is located in the snap-fit ​​groove 31, and the abutment part 1 is oriented towards the template side. This facilitates the snap-fit ​​of the reinforcing bar while ensuring the thickness of the concrete pouring outside the reinforcing bar mesh, reducing the possibility of the reinforcing bar being exposed. The semi-circular snap-fit ​​groove 31 makes the side wall of the snap-fit ​​groove 31 fit with the reinforcing bar, improving the stability of the reinforcing bar snap-fit. The connection plate 2, the abutment part 1 and the first snap-fit ​​part 3 are integrally set so that when the pad is subjected to external force, the connection plate 2, the abutment part 1 and the first snap-fit ​​part 3 are not easy to separate under the action of external force.

[0028] Example 2 Reference Figure 2 and Figure 3 The difference between this embodiment and Embodiment 1 is that the snap-fit ​​groove 31 is U-shaped, and the side of the first snap-fit ​​part 3 away from the connecting plate 2 is provided with an arc-shaped sliding plate 4 that is spliced ​​with the inner sidewall of the snap-fit ​​groove 31 to form an annular shape. The first snap-fit ​​part 3 has a sliding groove 32 that allows the sliding plate 4 to fully enter. One end of the sliding plate 4 is inserted into the sliding groove 32 and is slidably connected to the first snap-fit ​​part 3. The sliding groove 32 is provided with a first spring 41, one end of which is fixedly connected to the sidewall of the first snap-fit ​​part 3, and the other end of the first spring 41 is fixedly connected to the end of the sliding plate 4 inserted into the sliding groove 32.

[0029] Reference Figure 3 and Figure 4 The end of the sliding plate 4 away from the first spring 41 can be inserted into the first snap-fit ​​part 3, and the first snap-fit ​​part 3 is provided with a fixing member 42 for fixing the sliding plate 4.

[0030] The first snap-fit ​​part 3 has a fixing groove 33 that is adapted to the end of the sliding plate 4 away from the first spring 41. The fixing member 42 includes a snap-fit ​​block 421 located in the fixing groove 33. The first snap-fit ​​part 3 has a receiving groove 34 that is adapted to the snap-fit ​​block 421 and communicates with the fixing groove 33. One end of the snap-fit ​​block 421 is inserted into the receiving groove 34 and is slidably connected to the first snap-fit ​​part 3.

[0031] Reference Figure 3 and Figure 4 The receiving groove 34 is provided with a second spring 422, one end of which is fixedly connected to the first snap-fit ​​part 3, and the other end of the second spring 422 is fixedly connected to the end of the snap-fit ​​block 421. The end of the snap-fit ​​block 421 away from the second spring 422 is configured as an inclined surface that is inclined towards the side close to the fixed groove 33 and parallel to the moving direction of the sliding plate 4 blocking the snap-fit ​​groove 31. The end of the sliding plate 4 away from the first spring 41 is provided with a mounting groove 43, and the snap-fit ​​block 421 can be inserted into the mounting groove 43.

[0032] The sliding plate 4 is fully inserted into the first snap-fit ​​part 3, and the first spring 41 is compressed. At this time, the first snap-fit ​​part 3 is moved closer to the steel bar until the steel bar is snapped into the snap-fit ​​groove 31. The first spring 41 returns to its deformation and pushes the sliding plate 4 to slide away from the inside of the first snap-fit ​​part 3 until the end of the sliding plate 4 away from the first spring 41 is inserted into the fixing groove 33 and contacts the inclined surface of the snap-fit ​​block 421. The sliding plate 4 continues to move and presses the snap-fit ​​block 421, and the second spring 422 is compressed until the mounting groove 43 is directly opposite the snap-fit ​​block 421. At this time, the second spring 422 returns to its deformation and pushes the snap-fit ​​block 421 to be inserted into the mounting groove 43. At this time, the sliding plate 4 and the inner wall of the snap-fit ​​groove 31 are spliced ​​into a ring, and the fixing is completed.

[0033] The implementation principle of Example 2 is as follows: the sliding plate 4 is driven to fully enter the first snap-fit ​​part 3 and snap the steel bar into the snap-fit ​​groove 31. The first spring 41 pushes the sliding plate 4 to move until the end of the sliding plate 4 away from the first spring 41 contacts the inclined surface of the snap-fit ​​block 421. The sliding plate 4 continues to move and press the snap-fit ​​block 421 until the mounting groove 43 is directly opposite the snap-fit ​​block 421. At this time, the second spring 422 pushes the snap-fit ​​block 421 to be inserted into the mounting groove 43.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
