Description

Technical Field

[0001] The utility model belongs to the technical field of concrete engineering, and in particular relates to a concrete steel bar protective layer pad. Background Art

[0002] Concrete is one of the most important civil engineering materials in contemporary times. It has the characteristics of abundant raw materials, low price and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability and wide range of strength grades. These characteristics make it widely used. It is not only used in various civil engineering projects, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc. Concrete is also an important material. The basic principle of concrete steel bar protective layer pad is to use concrete prefabricated pads, fix them with wire ties, and use them for cast-in-place concrete structure steel bar protective layer, so that the reinforced concrete structure has a corresponding steel bar protective layer thickness, so that the reinforced concrete components can be in the applicable external environment, without the steel bars being corroded beyond the design requirements, and the durability of the concrete structure is achieved.

[0003] The existing concrete steel bar protective layer pads are prone to deflection and fall off during concrete pouring and vibration, and it is impossible to ensure that the pads are perpendicular to the concrete formwork surface, which easily increases the thickness error of the concrete steel bar protective layer and affects the durability of the concrete structure. For this reason, we propose a concrete steel bar protective layer pad. Summary of the invention

[0004] The purpose of the utility model is to provide a concrete steel bar protective layer pad to solve the problem proposed in the above background technology that the existing concrete steel bar protective layer pad is usually tied to the stressed steel bar with a wire when in use, and it is impossible to ensure that the pad is perpendicular to the formwork board surface during concrete pouring and vibration, which easily increases the thickness error of the concrete steel bar protective layer and affects the durability of the concrete structure.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a concrete steel bar protective layer pad, including a pad assembly, the pad assembly including a pad body, a stressed steel bar placement groove and a distribution steel bar placement groove, the stressed steel bar placement groove is arranged vertically in the center of the front surface of the pad body, the distribution steel bar placement groove is arranged horizontally in the center of the front surface of the pad body and crosses with the stressed steel bar placement groove, and also includes a pad fixing wire, the pad fixing wire is pre-embedded and installed on the pad body, and the pad fixing wire includes two wires arranged in a cross.

[0006] Preferably, the pad block assembly has grooves for placing stressed steel bars and grooves for placing distributed steel bars arranged in a cross pattern, and can be set at intersection nodes of the steel mesh.

[0007] Preferably, the pad block fixing wire is pre-buried and installed with the pad block body, and two pad block fixing wires penetrate the pad block body in a cross-arrangement, which can cross-bind to better fix the pad block.

[0008] Compared with the prior art, the beneficial effects of the utility model are:

[0009] (1) Existing concrete reinforcement protective layer pads are usually tied to the stressed reinforcement with a wire tie when in use. They are prone to deflection and falling off during concrete pouring and vibration, and cannot ensure that the pad is perpendicular to the concrete formwork surface. This easily increases the error in the thickness of the concrete reinforcement protective layer and affects the durability of the concrete structure. By providing a groove for placing stressed reinforcement, a groove for placing distributed reinforcement and two fixed binding wires on the pad, the pad can be effectively prevented from deflecting and falling off, ensuring that the pad is perpendicular to the concrete formwork surface, ensuring that the thickness of the concrete reinforcement protective layer meets the design and specification requirements, and improving the durability of the concrete structure.
