Description

Reusable PC reserved steel bar positioning device Technical Field The invention relates to the technical field of building construction, in particular to a reusable PC reserved steel bar positioning device. Background In recent years, the assembled structure is widely applied in the field of civil and industrial building construction. Before construction, reserved steel bars need to be buried in the corresponding wall column areas so as to facilitate the installation of PC prefabricated components. The positioning accuracy of the reserved steel bars directly influences the hoisting quality of the PC prefabricated parts. At present, three common reserved steel bar positioning modes are positioning by a positioning plate, positioning by a wood template and welding and positioning by steel bars. The positioning plate has good positioning effect, is a disposable product due to different reinforcement of each column, has high cost, is convenient to position and process, is extremely easy to deviate due to vibration in the concrete pouring process, cannot guarantee the positioning effect, has poor positioning effect due to the welding and positioning of the reinforcing steel bars, and can generate stress concentration at welding positions to influence the structural quality. Therefore, it is necessary to design a PC reserved steel bar positioning device which can be reused, is accurate in positioning and is suitable for different sizes. Disclosure of Invention The invention aims to provide a reusable PC reserved steel bar positioning device, which solves the problems of high cost, easy displacement, influence on structural quality and the like of the positioning device in the prior art. In order to achieve the above purpose, the present invention provides the following technical solutions: A reusable PC reserved rebar positioning device, comprising: each fixing unit is detachably clamped on the reserved steel bar to be positioned; And the connecting rods are connected with adjacent fixing units, so that all the fixing units form an integrated positioning frame. In some embodiments, the fixing unit includes an angle fixing plate and a fixing plate, where the angle fixing plate is a 90 ° included angle and is used for clamping on a single reserved steel bar at the column angle, and the fixing plate is a straight line and is used for clamping on a single reserved steel bar at the column edge. In some embodiments, the angle fixing plate comprises a first lobe and a second lobe which are matched with each other, the first lobe is L-shaped, a first arc-shaped groove is formed in the inner side of an L-shaped corner of the first lobe, a second arc-shaped groove is formed in the outer side of the L-shaped corner of the second lobe, after the first lobe and the second lobe are assembled in a involution mode, the first arc-shaped groove and the second arc-shaped groove jointly form a circular clamping hole for reserving reinforcing steel bars at the corner of a clamping column, the fixing plate comprises a third lobe and a fourth lobe which are matched with each other, the third lobe and the fourth lobe are all linear, and after involution and assembly, a circular clamping hole for reserving the reinforcing steel bars at the edge of the clamping column is formed.
