Abstract

The utility model relates to a prefabricated bridge deck steel bar positioning frame which comprises 4 side templates arranged according to the length and width of a prefabricated bridge deck, wherein at least 2 horizontal support rods are welded on the outer wall of each side template, each horizontal support rod is perpendicular to the plate surface of the side template, two limiting blocks are welded on the top surface of each horizontal support rod, a steel bar positioning rod is movably erected on each horizontal support rod on each side template, the distance between the steel bar positioning rod and the side template is set according to the design length of a reserved steel bar joint on the end surface of the prefabricated bridge deck, and the two limiting blocks on each horizontal support rod are respectively clung to the two sides of the steel bar positioning rod. When the bridge deck slab reinforcement is installed, the reinforcement positioning rods at two sides are respectively propped up against two ends of the reinforcement, so that the qualification of the reserved joint length of the reinforcement at the end face of the bridge deck slab and the neat end face can be ensured, and the construction efficiency can be improved.

Description

Prefabricated bridge deck steel bar positioning frame Technical Field The utility model belongs to the technical field of bridge construction, relates to prefabricated bridge deck construction, and in particular relates to a prefabricated bridge deck steel bar positioning frame. Background The prefabricated bridge deck slab is formed by prefabricating the bridge deck slab into a plurality of block sections and splicing wet joints on the bridge deck into a whole. When the bridge deck boards are prefabricated, reinforcing steel bar joints with certain lengths are reserved on the end faces of each bridge deck board, so that the bridge deck boards are in butt joint when wet joint construction is convenient. At present, when prefabricated bridge deck slab reinforcement is bound, the quality control of slab end reinforcement is often less ideal, mainly embodies in that the reinforcement reservation length is not enough, the reinforcing bar terminal surface is not neat, manual adjustment reinforcing bar work efficiency low grade problem, influences later stage bridge deck splicing construction quality. Disclosure of Invention The utility model aims to solve the problems and provide a prefabricated bridge deck slab reinforcement positioning frame which is used for controlling the quality of a reserved reinforcement joint on the end face of a bridge deck slab. The technical scheme of the utility model is as follows: A prefabricated bridge deck steel bar positioning frame is characterized by comprising 4 side templates which are arranged according to the length and width of a prefabricated bridge deck, wherein at least 2 horizontal support rods are welded on the outer wall of each side template, the heights of the horizontal support rods are equal, each horizontal support rod is perpendicular to the plate surface of the side template, two limiting blocks are welded on the top surface of each horizontal support rod, a steel bar positioning rod is movably erected on each horizontal support rod on each side template, the steel bar positioning rod is parallel to the plate surface of the side template, the distance between the steel bar positioning rod and the side template is set according to the design length of a reserved steel bar joint on the end surface of the prefabricated bridge deck, and two limiting blocks on each horizontal support rod are respectively clung to two sides of the steel bar positioning rod. According to the utility model, the steel bar positioning rod is arranged on the outer side of the bridge deck slab side template, so that the end face steel bar reservation joint of the bridge deck slab can be ensured to be qualified in length and neat in end face, repeated adjustment during steel bar installation can be avoided, the steel bar installation work efficiency can be improved, and the steel bar installation quality can be ensured. Drawings FIG. 1 is a schematic plan view of the present utility model; FIG. 2 is a schematic side elevational view of the present utility model; FIG. 3 is an enlarged view at A in FIG. 2; FIG. 4 is an enlarged view at B in FIG. 2; fig. 5 is a schematic view of the use state of the present utility model. Detailed Description As shown in fig. 1, 2, 3 and 4, the utility model comprises 4 side templates 1 arranged according to the length and width dimensions of the prefabricated bridge deck, at least 2 horizontal support rods 2 are welded on the outer wall of each side template, the heights of the horizontal support rods are equal, each horizontal support rod is perpendicular to the plate surface of the side template, two limiting blocks 3 are welded on the top surface of each horizontal support rod 2, a steel bar positioning rod 4 is movably erected on each horizontal support rod 2 on each side template, the steel bar positioning rod is parallel to the plate surface of the side template, the distance between the steel bar positioning rod and the side template is set according to the design length of a reserved steel bar joint on the end surface of the prefabricated bridge deck, and the two limiting blocks 3 on each horizontal support rod are respectively clung to the two sides of the steel bar positioning rod 4, so that the steel bar positioning rod cannot horizontally move. As shown in fig. 5, when the prefabricated bridge deck is constructed, 4 side templates 1 are installed and fixed, reinforcing steel bar positioning rods 4 are erected on the horizontal support rods 2 at the outer side of each side template, bridge deck reinforcing steel bars 5 are installed, two ends of each reinforcing steel bar 5 respectively penetrate through two opposite side templates and are tightly propped against the reinforcing steel bar positioning rods 4 at the two sides, so that the reserved joint length of reinforcing steel bars at each end face of the bridge deck is qualified, and the end faces are neat.
