Concrete grain pulling time subsidence degree monitoring hammer and using method thereof

Abstract

According to the concrete grain drawing time subsidence degree monitoring hammer and the using method thereof, the limitation that traditional concrete grain drawing time can only be judged according to experience of operators is broken through, the concrete grain drawing time subsidence degree monitoring hammer is made of the carbon steel, the center penetrating screws, the yellow anti-rust paint and the white nylon wires, manufacturing is easy, using in construction is easy and efficient, and the concrete grain drawing time subsidence degree monitoring hammer is suitable for popularization and application. The concrete grain pulling time subsidence degree monitoring device can accurately measure the optimal time in the concrete grain pulling stage and quantitatively master the grain pulling time, not only provides a grain pulling time detection method in the operation with high concrete grain pulling requirements in actual engineering, but also greatly improves the concrete apparent quality, and is very practical.

Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to a concrete drawing time settlement monitoring hammer and a use method thereof. Background Art

[0002] The control of the existing graining time after pouring of ground concrete can only be determined based on the experience of the operators. The graining timing is not selected accurately, which often leads to poor graining effects, uneven graining depths, fuzzing at the edges of the graining positions, discontinuous grains, and other problems. When problems are found, it is difficult to remedy the poor visual effect. In actual construction, the graining time is determined by experience, and there are large human interference factors. Problems often involve structural demolition, which is labor-intensive and material-intensive, affecting progress and wasting costs, and it is difficult to ensure quality. On the one hand, there is a lack of more accurate graining time and settlement detection tools and methods during the concrete floor operation stage. On the other hand, graining quality problems affect the visual quality and pose quality risks.

[0003] Therefore, there is a need for a device that is simple and efficient to use in construction and can accurately detect the slump of concrete during the ground concrete raftering operation stage, so as to ensure that the ground concrete raftering operation is carried out in the most appropriate time period, improve the visual quality of the concrete surface, ensure that the raftering is uniform and beautiful, and greatly reduce the investment in post-processing.

[0004] Invention requirements and content

[0005] The problem to be solved by the present invention is to provide a concrete graining time settlement monitoring hammer for determining the graining time of a concrete floor and a method for using the same, so as to avoid quality problems such as uneven graining depth, discontinuous graining, and fuzzing caused by improper selection of the graining time. The specification size and scale line position of the tool are determined through multiple actual tests, the concrete graining time settlement monitoring hammer and a method for using the same are improved, and a device is provided that is specifically used to control the graining time of a concrete floor. The operation is intuitive and simple, and the visual quality of the graining of the concrete floor can be improved.

[0006] The concrete drawing time and settlement monitoring hammer of the present invention is composed of three kinds of workpieces. The materials used for the workpieces include carbon steel, perforated screws, and white nylon rope. The carbon steel hammer body is coated with anti-rust paint. It has a simple structure and is intuitive and quick to operate. It provides a tool and a method of use for effectively controlling the drawing time of concrete floors, as shown in Figures 1, 2, 3, and 4. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The specific implementation of the present invention is described in detail below to facilitate a further understanding of the present invention.

[0012] The concrete graining time and settlement monitoring hammer of the present invention does not need to be coordinated with other auxiliary tools. After the concrete is vibrated and smoothed, the tool only needs to be placed on the concrete surface, as shown in the figure below, and read after standing for 30s±10s. If the concrete surface is in the 0 interval, it means that the concrete condition is suitable for graining; if the concrete surface is in the +1 interval, it means that the concrete strength is insufficient, the graining depth is too large, and the graining time needs to be delayed; if the concrete surface is in the -1 interval, it means that the concrete strength is too large, and the graining depth is too small.

[0013] Although the present invention has been disclosed as above by way of examples, it is not limited to the present invention. Any person skilled in the art may make various choices and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention is defined by the claims and their equivalents.
