Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and specifically to a steel reinforcement protective layer pad device. Background Technology

[0002] One of the key factors determining the durability and safety of reinforced concrete structures is whether the thickness of the concrete cover for the reinforcing bars meets the specifications. The thickness of the concrete cover for the reinforcing bars (the thickness of the concrete cover for the reinforcing bars) is generally controlled by concrete cover spacers. Specifically, before pouring concrete, concrete cover spacers are placed between the outside of the reinforcing bars and the formwork. In this way, after the concrete is poured, a concrete cover is formed on the outside of the reinforcing bars to prevent them from being exposed.

[0003] Chinese patent document with application number 202321228508.8 discloses a rebar protective layer anti-shattering pad, including a pad body, an upper groove, a lower groove, and anti-crushing material. The upper surface of the pad body has an upper groove extending to both sides, with the axis of the upper groove parallel to the upper surface. The lower surface of the pad body has a lower groove extending to both sides, with the axis of the lower groove parallel to the lower surface. The axis of the upper groove is perpendicular to the axis of the lower groove, and the bottom edges of the upper and lower grooves are on the same horizontal plane. This rebar protective layer anti-shattering pad has the following shortcomings: 1) The spacer block itself is not equipped with a fixing mechanism and needs to be fixed to the reinforcing bar by external ropes or wires, which can easily cause the spacer block to fall off and has low construction efficiency. 2) The spacer is directly connected to the reinforcing bar, and under the action of external force, the spacer is prone to cracking or even breaking; 3) There are usually multiple steel bars, and it is difficult to make the thickness of the protective layer of each steel bar consistent, which can easily lead to the phenomenon that the protective layer is too thin or too thick. 4) The thickness of the spacer is fixed, and the corresponding thickness of the spacer cannot be adjusted according to the different thicknesses of the concrete cover of the steel bars, resulting in poor applicability of the spacer. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a steel reinforcement protective layer pad device that is firmly fixed, not easy to fall off, easy to fix, has high construction efficiency, and prevents the main pad from cracking and breaking due to rigid compression.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A rebar protective layer spacer device includes a main spacer. One side of the main spacer is provided with a mating groove for engaging with the rebar. A buffer pad is provided in the mating groove. The main spacer is provided with a plurality of locking mechanisms for locking the rebar and arranged at intervals along the axial direction of the mating groove. Each locking mechanism includes a locking band and a locking member. The locking member is located on one side of the mating groove. One end of the locking band is located on the other side of the mating groove, and the other end is provided with a locking section for engaging with the locking member.

[0006] As a further improvement to the above technical solution: The locking section is provided with a plurality of locking teeth arranged at intervals along the extension direction of the locking section, and the locking device is provided with a locking channel for the locking section to be inserted, and a one-way locking block that cooperates with the locking teeth is provided in the locking channel.

[0007] The main pad has a through-hole, and the extension direction of the through-hole is perpendicular to the axis of the mating groove.

[0008] The alignment groove extends through to one end face of the main pad block.

[0009] The rebar protective layer pad device also includes alignment grooves for inserting multiple main pads to align each main pad with an alignment rod.

[0010] The cross-sections of the mating groove and the main pad block are arc-shaped.

[0011] The main pad block has a connecting part on the side away from the mating groove for detachable connection with the thickened pad block.

[0012] The steel reinforcement protective layer spacer device also includes a thickened spacer, one side of which is provided with a mating part for connecting with the connecting part, and the other side is provided with a butt joint with the same shape as the connecting part.

[0013] The connecting part and the mating part are respectively a sliding groove and a guide rod.

[0014] The cross-sections of the groove and guide rod are T-shaped or dovetail-shaped.

[0015] Compared with the prior art, the advantages of this utility model are: This utility model discloses a rebar protective layer spacer device. In use, the main spacer is placed on the outside of the rebar, ensuring a tight fit between the rebar and the buffer pad within the mating groove. Then, the locking section and locking fastener are locked together and secured to the outside of the rebar, thus fixing the main spacer and the rebar into a single unit. After concrete is poured at the location of the rebar, the main spacer acts as a barrier between the rebar and the outer formwork, forming a concrete retaining layer on the outside of the rebar and preventing exposure. First, the main spacer is fixed to the rebar via a locking mechanism, which, compared to external ropes or wires, ensures a secure and stable fixation, is easy to perform, and has high construction efficiency. Second, the main spacer, through the buffer pad, is in direct contact with the rebar, providing a flexible cushioning effect and preventing cracking or breakage due to rigid compression.

Detailed Implementation

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Example 1: Figure 1 and Figure 2 This invention illustrates a first embodiment of the rebar protective layer spacer device. The rebar protective layer spacer device of this embodiment includes a main spacer 1. One side of the main spacer 1 is provided with a mating groove 11 for cooperating with the rebar 5. A buffer pad 3 is provided in the mating groove 11. The main spacer 1 is provided with a plurality of locking mechanisms 4 for locking the rebar 5 and arranged at intervals along the axial direction of the mating groove 11. The locking mechanism 4 includes a locking band 41 and a locking member 42. The locking member 42 is provided on one side of the mating groove 11. One end of the locking band 41 is provided on the other side of the mating groove 11, and the other end is provided with a locking section 43 for locking with the locking member 42.

[0028] In use, the main pad 1 is placed on the outside of the reinforcing bar 5, so that the reinforcing bar 5 and the buffer pad 3 in the mating groove 11 are tightly fitted together. Then, the locking section 43 and the locking fastener 42 are locked and tightened on the outside of the reinforcing bar 5, so that the main pad 1 and the reinforcing bar 5 are fixed together. In this way, after pouring concrete at the location of the reinforcing bar 5, the main pad 1 acts as a barrier between the reinforcing bar 5 and the outer formwork of the reinforcing bar 5, forming a concrete retention layer on the outside of the reinforcing bar 5, preventing the reinforcing bar 5 from being exposed. First, the main pad 1 and the reinforcing bar 5 are fixed by the locking mechanism 4, which is relatively fixed by external ropes or wires. This not only makes the fixation firm and less likely to fall off, but also makes the fixing operation convenient and the construction efficiency high. Second, the main pad 1 is tightly fitted with the reinforcing bar 5 through the buffer pad 3, which is in direct contact and has a flexible buffering effect, which helps to prevent the main pad 1 from cracking or breaking due to rigid compression.

[0029] Furthermore, in this embodiment, the locking section 43 is provided with a plurality of locking teeth 431 arranged at intervals along the extension direction of the locking section 43, and the locking fastener 42 is provided with a locking channel 421 for the locking section 43 to be inserted. The locking channel 421 is provided with a one-way locking block 44 that cooperates with the locking teeth 431. When the locking section 43 is inserted into the locking channel 421, as the insertion depth changes, the one-way locking block 44 changes the locking position of the locking section 43 until the locking band 41 is tightly wrapped around the outside of the reinforcing bar 5. The one-way locking block 44 does not lock the locking section 43 during the insertion of the locking section 43 into the locking channel 421, but locks the locking section 43 during the withdrawal of the locking section 43 from the locking channel 421. This is a conventional structure. For example, the one-way locking block 44 is directly fixed to the inner wall of the locking channel 421, and the locking teeth 431 are triangular elastic teeth. The one-way locking block 44 compresses the locking teeth 431 to deform. The locking section 43 and the locking fastener 42 are locked together by the compressive force between the one-way locking block 44 and the corresponding locking teeth 431. Alternatively, the one-way locking block 44 is fixed to the inner wall of the locking channel 421 by an elastic part and can swing under the compressive force of the locking teeth 431, thereby enabling the locking section 43 to be inserted into the locking channel 421. When the locking teeth 431 are stuck between adjacent locking teeth 431, the locking section 43 is prevented from being pulled out of the locking channel 421.

[0030] Furthermore, in this embodiment, the main pad 1 has a through-hole alignment groove 12, and the extension direction of the alignment groove 12 is perpendicular to the axial direction of the mating groove 11. When multiple parallel reinforcing bars 5 are respectively equipped with this reinforcing bar protective layer pad device, the alignment rod 6 is inserted into the alignment groove 12 of the row of main pads 1, so that each main pad 1 can remain in a parallel position, thereby making the protective layer thickness of each reinforcing bar 5 consistent and preventing the protective layer thickness from being too thin or too thick.

[0031] Furthermore, in this embodiment, the alignment groove 12 extends through to one end face of the main pad 1, making it easier for the alignment rod 6 to be inserted into the alignment groove 12 from the end of the main pad 1, thus improving the convenience of operation.

[0032] Furthermore, in this embodiment, the cross-sections of both the mating groove 11 and the main pad 1 are arc-shaped. The arc-shaped cross-section of the mating groove 11 facilitates the fitting and contact of the arc-shaped main pad 1, and the arc-shaped cross-section of the main pad 1 facilitates its fitting and contact with the reinforcing bar 5.

[0033] Furthermore, in this embodiment, the side of the main pad 1 away from the mating groove 11 is provided with a connecting part 7 for detachable connection with the thickened pad 2. In this way, a thickened pad 2 can be added to the side of the main pad 1 away from the mating groove 11, thereby increasing the thickness of the concrete protective layer on the outside of the reinforcing bar 5.

[0034] Furthermore, in this embodiment, the mating groove 11 extends through both ends of the main pad block 1.

[0035] Example 2: Figure 3 and Figure 4 This paper illustrates a second embodiment of the rebar protective layer spacer device of this utility model. The structure of the rebar protective layer spacer device in this embodiment is basically the same as that in the first embodiment, except that the rebar protective layer spacer device further includes a thickened spacer 2. One side of the thickened spacer 2 has a mating part 8 for connecting with the connecting part 7, and the other side has a butt joint 9 with the same shape as the connecting part 7. The thickened spacer 2 is added to the side of the main spacer 1 away from the mating groove 11 through the mating part 8 and the connecting part 7, thereby increasing the thickness of the concrete protective layer outside the rebar 5. Furthermore, multiple thickened spacers 2 can be provided, with adjacent thickened spacers 2 connected to the mating part 8 through the corresponding butt joint 9. This allows the number of thickened spacers 2 to be adjusted according to the different thicknesses of the concrete protective layer outside the rebar 5, improving applicability.

[0036] Furthermore, in this embodiment, the connecting part 7 and the mating part 8 are a sliding groove and a guide rod, respectively, which facilitates docking and assembly.

[0037] Furthermore, in this embodiment, the cross-sections of the groove and the guide rod are T-shaped or dovetail-shaped.

[0038] Furthermore, in this embodiment, the connecting part 7 is a groove extending to both ends of the main pad 1, and the mating part 8 is a guide rod extending to both ends of the thickened pad 2.

[0039] Example 3: Figure 5 and Figure 6The present invention illustrates a third embodiment of the rebar protective layer spacer device. The structure of the rebar protective layer spacer device in this embodiment is basically the same as that in the first embodiment, except that the rebar protective layer spacer device further includes alignment grooves 12 for inserting multiple main spacers 1 to align each main spacer 1.

[0040] In this way, when multiple parallel reinforcing bars 5 are equipped with their respective protective layer spacer devices, the alignment rod 6 is inserted into the alignment groove 12 of the row of main spacers 1, so that each main spacer 1 can remain in a parallel position, thereby ensuring that the protective layer thickness of each reinforcing bar 5 is consistent and that the protective layer thickness is not too thin or too thick.

[0041] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
