Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy projects, and specifically relates to a new type of steel bar protective layer cushion block. Background Art
[0002] The steel bar protective layer cushion blocks have evolved from the initial production of mortar and cutting into squares to the currently commonly used arc-shaped cushion blocks in the market. All of them can only be tied and attached to the outside of a vertical or horizontal steel bar. Although the arc-shaped cushion blocks have stronger fitting degree and versatility with the steel bar than the square cushion blocks, they still float on the surface of the steel bar, are not firmly tied and fixed, are prone to displacement and inclination, and the cushion blocks swing in various postures up, down, left and right, unable to meet the requirement of uniform thickness of the protective layer. Summary of the Invention
[0003] In view of the above technical deficiencies, the purpose of the utility model is to provide a new type of steel bar protective layer cushion block, which uses two U-shaped grooves with different depths to not only clamp the outer steel bar but also have a good wrapping and restraining effect on the inner steel bar. The cushion block is flexible, stable and firm in tying, and can accurately control the error of the protective layer thickness.
[0004] To solve the above technical problems, the utility model adopts the following technical solutions:
[0005] The utility model provides a new type of steel bar protective layer cushion block, including a cushion block main body composed of a cuboid and a frustum. The upper part of the cushion block main body is a frustum, and the lower part is a cuboid; four arc-shaped notches are evenly distributed on the frustum from top to bottom; an inverted U-shaped groove and an arc-shaped groove perpendicular to each other are arranged at the bottom of the cuboid, and the inverted U-shaped groove and the arc-shaped groove horizontally penetrate the cuboid in two perpendicular directions;
[0006] The inverted U-shaped groove and the arc-shaped groove are different in depth and size;
[0007] Cross-shaped wire tying through holes are opened on the cuboid, and a wire tying groove hole is opened at the center position of the bottom surface of the cuboid.
[0008] Further, the size of the bottom arc notch in the arc-shaped notch is larger than the size of the top arc notch in the arc-shaped notch.
[0009] Further, the vertical height of the inverted U-shaped groove is greater than the vertical height of the arc-shaped groove, and the width of the inverted U-shaped groove is greater than the width of the arc-shaped groove.
[0010] The beneficial effects of the utility model are as follows:
[0011] 1. The overall structural shape of the steel bar protective layer cushion block of the utility model is in the shape of a pagoda, saving materials, with a reasonable shape, economic and applicable;
[0012] 2. Two U-shaped grooves with different depths and sizes can not only hold the outer steel bars in place but also have a good wrapping and restraining effect on the inner steel bars, which can fit and fix the double-layer steel bars to the greatest extent. It has a strong wrapping and restraining effect on both vertical and horizontal steel bars and can also be used when the directions and positions of the outer and inner steel bars are interchanged.
[0013] 3. The spacer bars can be tied flexibly, stably and firmly, and can accurately control the error of the protective layer thickness. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention. Embodiment 1
[0022] As Figures 1 - 3As shown in the figure, a new type of steel bar protection layer cushion block includes a cushion block main body 1 composed of a cuboid and a frustum of a pyramid. The upper part of the cushion block main body 1 is a frustum of a pyramid, and the lower part is a cuboid. Four arc-shaped notches 2 are evenly distributed on the frustum of the pyramid from top to bottom. An inverted U-shaped groove 3 and an arc-shaped groove 4 perpendicular to each other are arranged at the bottom of the cuboid, and the inverted U-shaped groove 3 and the arc-shaped groove 4 horizontally penetrate the cuboid in two perpendicular directions.
[0023] The depths and sizes of the inverted U-shaped groove 3 and the arc-shaped groove 4 are different.
[0024] Cross-shaped binding wire through holes 5 are provided on the cuboid (that is, four through holes that can flexibly pass through the binding wire in the left-right, front-back directions are arranged on the same section of the cuboid), and a binding wire slot hole 6 is provided at the center position of the bottom surface of the cuboid (that is, a communication hole is opened at the intersection point of the hole centers facing the direction of the binding steel bar), which is convenient for the binding wire to enter and exit from any angle for fastening.
[0025] The size of the bottom arc notch in the arc-shaped notch 2 is larger than the size of the top arc notch in the arc-shaped notch 2.
[0026] The vertical height of the inverted U-shaped groove 3 is greater than the vertical height of the arc-shaped groove 4, and the width of the inverted U-shaped groove 3 is greater than the width of the arc-shaped groove 4.
[0027] Usage method:
[0028] As Figures 4 - 5 shown in the figure, this cushion block only needs to be rotated 90 degrees to adapt to the changing positions of horizontal steel bars and vertical steel bars. The different depths of the inverted U-shaped groove and the arc-shaped groove 4 respectively match the sizes of the steel bars. During use, it only needs to be placed at the cross point of the steel bars, and it has a good wrapping and restraining effect on both the outer layer and the inner layer of steel bars. Four-direction through holes are provided on the cushion block to facilitate the binding wire to enter and exit from any angle for binding and fastening.
[0029] This protection layer cushion block needs to be made of high-strength concrete material, which can minimize the volume of the cushion block to the greatest extent. Determine the production size according to the horizontal steel bars, vertical steel bars and the protection layer thickness in the drawing. When designing the mold, it can be accurately oriented for two kinds of steel bar specifications, or the variation range values of two U-shaped groove openings can be given according to the common steel bar specifications for batch production to improve the versatility of the cushion block.
[0030] Obviously, those skilled in the art can make various modifications and variations 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 equivalent technologies, the present invention also intends to include these modifications and variations.
