Novel concrete top die stick

Abstract

The invention provides a novel concrete top die stick. The novel concrete top die stick comprises a top die stick body, the cross section of the top die stick body is rectangular, iron wires are pre-buried symmetrically at the two sides of the top die stick body, and meanwhile the distance between the outermost wire and the end, the same side of the outermost wire, of the top die stick body is 1 mm smaller than the thickness of a concrete protective layer. The novel concrete top die stick has the advantages of being simple and practical in structure, safe in operation, low in cost and the like, the top die stick body can be accurately fixed on a horizontal rebar during wall rebar binding through the pre-buried iron wires, rebar framework offset can be prevented and the thickness of the concrete protective layer can be controlled, and the construction quality is sufficiently ensured. Compared with an existing concrete top die stick depending on a notch to fix, the novel concrete top die stick is more stable and reliable in structure and more convenient to bind and fix, and compared with a steel top die stick, the novel concrete top die stick is low in cost.

Description

technical field [0001] The invention belongs to the technical field of construction, and in particular relates to a novel concrete top mold stick. Background technique [0002] In the construction of reinforced concrete walls, concrete top formwork sticks are generally used to control the thickness of the concrete protective layer. At present, the main concrete top formwork sticks are grooves reserved at both ends of the top formwork sticks, and they are stuck on the horizontal bars during use. The top mold stick is more prone to misalignment and cannot play a role in controlling the distance between the horizontal rib and the formwork. Another commonly used top mold stick is to use a steel bar welded with buckles, the buckle is stuck on the horizontal bar, and the thickness of the concrete cover is controlled by the two ends of the steel bar against the steel formwork on both sides, but this kind of top mold stick It will increase the cost of the project. If it is used in ...

[0002] In the construction of reinforced concrete walls, concrete top formwork sticks are generally used to control the thickness of the concrete protective layer. At present, the main concrete top formwork sticks are grooves reserved at both ends of the top formwork sticks, and they are stuck on the horizontal bars during use. The top mold stick is prone to misalignment and cannot play a role in controlling the distance between the horizontal rib and the formwork

Another commonly used top mold stick is to use a steel bar welded with buckles, the buckle is stuck on the horizontal bar, and the thickness of the concrete cover is controlled by the two ends of the steel bar against the steel formwork on both sides, but this kind of top mold stick It will increase the cost of the project. If it is used in the wooden formwork, the two ends of the top mold stick will easily penetrate the wooden formwork
