The invention discloses a construction method for positioning upper reinforcements of a concrete floor slab by using tool type supports, and the method comprises the following steps of: A, fabricating the tool type supports: bending a plurality of reinforcements into triangular supports, distributing the plurality of formed reinforcements at intervals, and connecting a steel angle to the joint of each reinforcement bent into the triangular support to form a triangular truss, wherein support cushion blocks are arranged at the lower two ends of the bottom surface of the triangular truss, respectively, and a floor slab protective layer limiting reinforcement is arranged below the bottom surface of the triangular truss; B, strapping the concrete floor slab reinforcements to form a reinforcement net; and C, mounting the tool type supports: connecting the plurality of tool type supports fabricated in the step A with the concrete floor slab reinforcement net fabricated in the step B; and after the step C is completed, paving a working surface on the plurality of tool type supports so that workers can perform concreting construction work on the reinforcement net on the working surface. The method provided by the invention can be used for guaranteeing the thickness of the protective layer of the upper reinforcements of the floor slab, improving the construction progress and saving the engineering cost.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for positioning steel bars on the upper part of a concrete floor with a tool-type support. Background technique [0002] With the development of the times, the construction technology of construction engineering has been perfected day by day. In the concrete pouring construction of construction engineering, especially in the construction of concrete slabs, people pay more and more attention to the protection layer of steel bars on the upper part of the slab during construction. The traditional stool iron support is not economical, and the steel bars on the upper floor are easy to trample, deform and sink during the construction process, and the thickness of the protective layer of a large number of steel bars on the upper floor does not meet the requirements of the design specifications, which affects the construction quality and efficiency and ...
