Description

Technical Field

[0001] The utility model relates to the technical field of concrete construction, in particular to a convenient binding-free cement pad for grid concrete components. Background Art

[0002] The fiber reinforced composite mesh is lightweight, high-strength, corrosion-resistant, and has high node strength. It has excellent stress transfer performance and interface bonding strength, and is effective in the application of surface crack resistance in new large-volume concrete structures. When using the mesh, it is required to be placed in the concrete protective layer between the steel bars and the formwork. In order to exert the anti-cracking effect of the mesh, there is a specified controllable distance between the three. In order to control the distance between the steel bars and the mesh, and the mesh and the formwork, cement pads are currently tied to the steel bars to control the distance between the steel bars and the mesh, and cement pads are also tied to the mesh to control the distance between the grid and the formwork.

[0003] The disadvantages of the above process are that it must be tied with wire, which has low construction efficiency. The exposed metal wire is prone to rust spots, affecting the appearance quality of the concrete. At the same time, the metal wire will interfere with the detection accuracy of the steel bar protection layer thickness by the steel bar protection layer measuring instrument. In addition, tying cement pads on the mesh limbs has the risk of blocking the passage of large aggregates in the concrete, affecting the surface rebound strength of the concrete. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model discloses a convenient binding-free cement pad for grid concrete components. Through the specific groove anti-slip structure design, the cement pad can be directly hung at the grid node without falling off, thereby effectively improving the construction efficiency of the grid and facilitating uniform concrete pouring on both sides of the grid, effectively reducing the occurrence of cracks on the surface of large-volume concrete.

[0005] The utility model provides a convenient binding-free cement pad for a grid concrete component.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a convenient binding-free cement pad for grid concrete components, comprising a cement pad body, the cement pad body is prefabricated with cement mortar and is an elliptical solid body, and a groove is provided in the middle position of the cement pad body, an introduction opening is further provided on one side of the groove, the introduction opening is connected with the groove, and an anti-slip structure of an anti-slip barb is provided on one side of the groove and the introduction opening, a semi-circular arc surface is provided on the outer wall of the side end of the cement pad body, and the pad body is used for spatial positioning and fixation of the fiber reinforced composite material grid in the concrete protective layer, and is installed on the side in contact with the formwork.

[0007] Preferably, the groove is oval or square, and the groove is through-through from top to bottom, and its size is adjustable, with a length of 30-45 mm and a width of 5-10 mm.

[0008] Preferably, the introduction opening extends to the outside of the cement pad body, and the narrowest part of the introduction opening allows the grid limbs to pass smoothly.

[0009] Preferably, after the mesh limb is inserted into the introduction opening, combined with the effect of gravity and the introduction angle provided by the anti-detachment hook, the mesh limb cannot slide out from the original direction.

[0010] Preferably, the introduction angle is the angle between the introduction plane of the introduction opening and the horizontal plane, wherein the introduction angle is between 20° and 40°.

[0011] Preferably, the semicircular arc surface protrudes outwards and contacts the template, and its radius is adjustable within a range of 5-10 mm.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model uses a convenient binding-free cement pad for grid concrete, which can be directly hung at the grid node, and has high construction efficiency. It avoids the use of binding wires, solves the problem of metal corrosion, and does not affect the detection accuracy of the steel bar protective layer thickness by the steel bar protective layer measuring instrument after demolding.
