Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to a reinforcement member supporting device and a construction method. Background Art

[0002] Steel bars exposed to the atmosphere or other media are easily corroded and rusted, which reduces the effective cross-section of the steel bars and affects the stress of the structure. Therefore, it is necessary to stipulate that steel bars in different use environments have a steel bar protective layer of minimum thickness according to durability requirements to ensure that the steel bars do not rust during the service life of the component, which would reduce the reliability of the structure.

[0003] Before concrete construction of reinforced components, pads are needed to ensure the installation accuracy of the overall structure due to deviations in the positions of the components (such as binding accuracy or material deviation) and the influence of ground flatness. This ensures that the later steel bar protection layer meets construction specifications. Traditional concrete pads can only support the lower steel bars, but the position and height of concrete pads cannot be adjusted. If the height of multiple pads is accumulated, the overall stability performance is difficult to guarantee. In addition, operators are prone to crushing or kicking away traditional pads during operation. As a result, the thickness of the concrete protection layer is insufficient or even the steel bars are exposed, which seriously affects the construction quality.

[0004] Therefore, in order to solve the above problems, a steel bar protective layer support structure is needed to solve the above problems. Summary of the invention

[0005] In view of this, the steel bar component support device of the present technical solution is height-adjusted through a support rod mechanism in cooperation with a support sleeve, which facilitates controlling the various construction positions of the steel bar body to be on the same horizontal plane, so that the steel bar protective layer meets the construction requirements after the later pouring. At the same time, the support device facilitates adjustment and control of the overall height to ensure a uniform thickness of the concrete protective layer and improve construction quality.

The limit ring assembly is fixedly connected and installed on the support seat 43, and the two limit arm assemblies with the same structure cooperate with the adjustment gear for adjustment, so that the overall installation height adjustment of the support rod mechanism 4 can be achieved.

[0027] In this embodiment, the left limit arm assembly and the right limit arm assembly 41 are arranged symmetrically with respect to the adjustment gear, and the left limit arm assembly includes a limit arm 5, a bar-shaped tooth 7 arranged along the length direction of the limit arm 5, and a guard plate protruding from the surface of the limit arm; the adjustment gear meshes with the bar-shaped tooth 7. A guard plate structure is formed on the protrusion of the limit arm, and the limit arm 5 is provided with a bar-shaped tooth 7, which meshes with the adjustment gear. When the adjustment hand wheel 3 and the adjustment gear rotate, the limit arm 5 can be driven to move in the vertical direction.
