Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a novel steel bar protective layer pad. Background Art

[0002] The steel bar protective layer pads have evolved from the original mortar-cut square blocks to the arc-shaped pads commonly used in the market. However, these pads can only be tied and attached to the outside of a vertical or horizontal steel bar. Although the arc-shaped pads have a better fit and versatility with the steel bars than the square pads, they still float on the surface of the steel bars, are not firmly tied and fixed, and are prone to displacement and tilt. The pads also swing up and down and left and right in different postures, and cannot meet the requirements for uniform and consistent thickness of the protective layer.

[0003] Therefore, a new type of steel bar protective layer pad is specially designed. The protective layer pad adopts two U-shaped grooves of different depths. While clamping the outer layer of steel bars, it also has a good wrapping and restraining effect on the inner layer of steel bars. The pad is flexible, stable and firm in binding, and can accurately control the protective layer thickness error. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model aims to provide a novel steel bar protective layer pad.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The utility model provides a novel steel bar protective layer pad, comprising a pad body arranged in a frustum-shaped shape, the pad body being evenly distributed with four arc notches from top to bottom; the bottom of the pad body being located at a relative bottom arc inverted position in the arc notch and being laterally provided with an inverted U-shaped groove; the bottom of the pad body being located at another relative bottom arc inverted position in the arc notch and being longitudinally provided with an arc-shaped groove; a wire tying hole is respectively provided on both sides of the transverse direction and both sides of the longitudinal direction of the middle part of the pad body, and the wire tying hole is located on the arc notch in the pad body; a wire tying groove is provided at the center position of the bottom surface of the pad body.

[0007] Preferably, the size of the bottom circular arc inverted opening among the four circular arc notches is greater than the size of the top circular arc inverted opening among the circular arc notches.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1, as Figures 1 to 5 As shown, a new type of steel bar protective layer pad includes a pad body 1 arranged in a frustum shape, and the pad body 1 is evenly distributed with four arc grooves 2 from top to bottom; the bottom of the pad body 1 is located at a relative bottom arc inverted position in the arc groove 2, and an inverted U-shaped groove 3 is provided in the horizontal direction; the bottom of the pad body 1 is located at another relative bottom arc inverted position in the arc groove 2, and an arc groove 4 is provided in the longitudinal direction; a wire binding hole 5 is respectively opened on both sides of the horizontal direction and both sides of the longitudinal direction of the middle part of the pad body 1, and the wire binding hole 5 is located on the arc groove 2 in the pad body 1; a wire binding slot 6 is opened at the center position of the bottom surface of the pad body 1. Among them, the inverted U-shaped groove 3 and the arc-shaped groove 4 have different depths and arc sizes, which can well adapt to the different sizes and relative positions of vertical and horizontal steel bars; the wire binding hole 5 (that is, four through holes are set on the same section in the middle of the pad body 1, and the wire binding wire can be flexibly passed through the left and right directions and the front and back directions) and the wire binding slot hole 6 (that is, a connecting hole is opened at the center intersection of the holes toward the direction of the tied steel bars) to ensure that the wire binding wire can flexibly pass through the tied steel bars from all angles.

[0024] Further, in an embodiment, Figure 1 , Figure 4 and Figure 5 As shown, the size of the bottom arc inverted opening of the four arc notches 2 is greater than the size of the top arc inverted opening of the arc notches 2 .

[0025] Further, such as Figure 1 , Figure 4 and Figure 5 As shown, the vertical height of the inverted U-shaped groove 3 is greater than the vertical height of the arc-shaped groove 4.

[0026] Further, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the vertical height of the wire-binding hole 5 is greater than the vertical height of the inverted U-shaped groove 3 .

[0027] In addition, it should be noted that the total height of the steel bar protective layer pad matches the size of the steel bar and the thickness of the protective layer; and according to the actual manufacturing material conditions, the bottom and upper diameters of the steel bar protective layer pad can be adaptively and freely adjusted according to the strength of the material used to make the pad, which will not be described in detail in this application.

[0028] Instructions for use: The pad in the utility model has inverted U-shaped grooves 3 and arc grooves 4 of different depths that match the sizes of the steel bars respectively. According to the actual working conditions, when using it, it is only necessary to align the inverted U-shaped grooves 3 and arc grooves 4 in the pad and place them on the cross intersection of the steel bars, and then use wire tying to fasten them through the 4 arc notches and 4 wire holes on the surface of the pad, so as to achieve the purpose of having a good wrapping and restraining effect on both the outer and inner layers of the steel bars. It should be noted that the pad only needs to be rotated 90° to adapt to the changing positions of the horizontal and vertical steel bars, and it is easy to use.

[0029] Note:

[0030] (1) At present, since the use of plastic pads is prohibited in the construction industry, the protective layer pads in the utility model are made of high-grade concrete material, which can minimize the volume of the pads;

[0031] (2) The manufacturing dimensions need to be determined according to the horizontal and vertical steel bars and the thickness of the protective layer in the drawing. In this way, when designing the mold, it can be precisely corresponding to the two types of steel bar specifications and sizes for special purposes, or it can be mass-produced according to the range of variation of the two grooves (U-shaped groove 3 and arc-shaped groove 4) given according to the commonly used steel bar specifications and sizes, thereby improving the versatility of the pad.

[0032] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
