Description
Technical Field
The utility model relates to the technical field of bridge construction, in particular to a precast beam reserved reinforcing steel bar protection device.
Background
The prefabricated bridge beam has reserved reinforcing bars on the top surface of the traffic lane board, the distance is generally 10 cm-15 cm, the height is about 10cm higher than that of the prefabricated beam, and the prefabricated beam and the bridge deck pavement layer are mainly connected, as shown in figure 1. In the process of erecting the precast beams, the beam transporting gun carrier needs to pass through the erected precast beams, and the reserved steel bars influence the driving safety of the gun carrier. At present, two common methods are adopted for the situation, namely, sand is used for bedding, and the reserved reinforcing steel bars are crushed and bent and then corrected after the beam transportation is finished. However, the above treatment methods have drawbacks, if sand is adopted for bedding, the sand will be lost and pollute the lower structure of the bridge and the precast beam, and meanwhile, the sand is difficult to clean in the later period, and generally, only water trucks can be used for flushing to the position below the bridge, so that resource waste is caused. If the reserved steel bars are subjected to bending after the beam transportation is finished, the reserved steel bars are usually screw-thread steel, so that the reserved steel bars are brittle in material, are bent and corrected for many times, and are easy to break. Therefore, it is necessary to provide a protection device for protecting the reserved steel bars, which has simple structure, reliable performance and convenient assembly and disassembly.
Disclosure of Invention
The utility model aims to provide a precast beam reserved steel bar protection device which is convenient for protecting reserved steel bars on precast beams, prevents a beam transporting gun carrier from crushing the reserved steel bars, and is convenient for disassembly and assembly.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides a precast beam reserves reinforcing bar protection device, includes a plurality of battens, and the batten both ends wear to establish on connecting rope and the batten can follow and connect the rope and remove, the batten side is provided with the side recess that is used for covering precast beam upper surface reservation reinforcing bar, is connected with the rubber strip between side recess both sides, the length and the height of batten are all greater than the length and the height of reservation reinforcing bar.
Further, rope ends are arranged at two ends of the connecting rope, and the connecting rope is located at two sides of the reserved steel bars.
Further, through holes for the connecting ropes to pass through are formed in the two ends of the battens, and the diameters of the through holes are larger than those of the connecting ropes.
Further, the rubber strips are fixed on two sides of the side concave parts through thumbtacks.
Further, the connecting rope is a soft steel rope, and the length of the connecting rope is longer than the arrangement length of the reserved steel bars.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model is provided with a plurality of battens and connected through the connecting rope, each batten is placed in a seam of the reserved steel bar, so that the girder transporting gun carriage can run from square wood to avoid damage of the girder transporting gun carriage to the reserved steel bar, and the side surface of the batten is provided with a side concave part and is connected with a rubber strip, thereby preventing the batten from deviating from the reserved steel bar. When the device is installed, the reserved reinforcing steel bars only need to extend into the side concave parts, when the device is detached, the connecting ropes only need to be pulled, and the disassembling and assembling processes do not need parts such as screws, so that the device is more convenient to disassemble and assemble, and meanwhile, the device can be recycled, and the sand and soil waste in the traditional method is effectively reduced. The sand soil is effectively prevented from polluting the structure, and the reserved steel bars are effectively prevented from being damaged due to repeated bending.

Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
Example 1:
referring to fig. 2-3, the utility model provides a precast beam reserved steel bar protection device, which comprises a plurality of battens 3, wherein two ends of each batten 3 are arranged on a connecting rope 4 in a penetrating way, the battens 3 can move along the connecting ropes 4, side surfaces of the battens 3 are provided with side concave parts 6 for covering reserved steel bars 2 on the upper surface of a precast beam 1, referring to fig. 4, rubber strips 7 are connected between two sides of the side concave parts 6, the battens 3 are prevented from deviating from the reserved steel bars 2 through the rubber strips 7, and the length and the height of each batten 3 are larger than those of the reserved steel bars 2, so that the reserved steel bars 2 can be protected through the battens 3, and the reserved steel bars 2 cannot be bent by girder transporting gun cars. In order to prevent the batten 3 from being separated from the connecting rope 4, rope end parts 5 are arranged at two ends of the connecting rope 4, and the connecting rope 4 is positioned at two sides of the reserved steel bar 2.
