Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a reinforcing mesh support auxiliary device for concrete cover construction. BACKGROUND

[0002] High-precision ground construction is a high-precision ground construction process, which aims to control the floor flatness within a very small range through tools and control methods. In high-precision ground construction, the distance between the concrete cover in the concrete structural member and the outer edge of the outermost reinforcing steel bar is required to be maintained within a certain range, so as to avoid the direct exposure of reinforcing steel bars from concrete. In the traditional high-precision ground integrated construction process, the horse stool bar is a commonly used temporary support structure, which is used to support the reinforcing mesh to control the flatness and elevation of the ground. However, with the continuous improvement of the quality requirements of the building industry on ground construction, the horse stool bar gradually exposes some defects that cannot be ignored, mainly in the following aspects:

[0003] 1. prone to deformation, low flatness control precision: the horse stool bar is usually made of metal or other materials, and when it bears the pressure of ground concrete pouring, the deformation will cause the horse stool bar to fail to maintain the initial set height and position, thereby affecting the flatness of the ground. Even if the horse stool bar is accurately measured and positioned before construction, due to the existence of deformation, the flatness of the final ground is still difficult to meet the requirements of high precision.

[0004] 2. installation error accumulates to affect flatness: in actual construction, the installation of the horse stool bar needs manual operation, and it is inevitable that there will be certain installation errors, and moreover, as the construction area increases, these installation errors will continue to accumulate, further reducing the overall flatness of the ground. For example, in large-area ground construction, if there is a slight deviation in the installation height of each horse stool bar, after the superposition of a large number of horse stool bars, the flatness deviation of the entire ground will become quite obvious.
