Description

A quick-detachable combined prefabricated beam edge protection device

Technical Field

The utility model belongs to the technical field of highway bridge engineering, in particular to a quick-detachable combined prefabricated T-beam edge protection device.

Background Art

With the rapid development of my country's transportation construction, the prefabrication and installation of prestressed T-beams are increasingly widely used in highway and water conservancy projects. After the T-beam is erected, it is necessary to carry out multiple processes such as wet joint treatment of panels, ends, and diaphragms and tensioning of negative bending tendons. The pouring of the bridge's anti-collision guardrail will not be carried out until the previous multiple processes are completed. Therefore, the bridge side is in a suspended and unprotected state for a long time after erection, and workers are very likely to fall when working at heights. The usual protective measures are generally the following: one is to set up colored strips on the side of the bridge for safety warnings, one is to connect the steel bars and steel pipes by welding to the reserved steel bars and then hang a dense mesh, and the other is to drill holes in the prefabricated beam body and install expansion screws for steel fence installation. The above several enclosure methods either fail to achieve the enclosure effect, or the process is more complicated, or it will cause damage to the beam body, and the use effect is poor. In order to solve the above technical problems, this application document provides a quick-disassembly combined prefabricated beam edge protection device.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Specific embodiment one:

Please refer to Figures 1-4. The utility model is a quick-detachable combined prefabricated beam edge protection device, including a telescopic vertical pole. A panel 1 is fixed to one side of the upper end of the telescopic vertical pole. Two L-shaped buckles 2 are installed on the panel 1. A 凵-shaped groove 5 is fixed to the lower half of the telescopic vertical pole on the same side as the panel 1. A pair of wing-shaped clamps are symmetrically fixed on both sides of the lower end of the telescopic vertical pole. A triangular support frame 9 is fixed to the side of the lower end of the telescopic vertical pole away from the 凵-shaped groove 5, and the wing-shaped clamp is used to make the vertical pole stand firmly and stably on the prefabricated beam. On the one hand, the 凵-shaped groove 5 supports the bottom of the protective net 11, and on the other hand, it is convenient for the splicing of the protective net 11.

The telescopic upright pole comprises an upper upright pole 3 and a lower upright pole 4 connected by a telescopic sleeve. A fastening bolt 8 is threadedly connected on the lower upright pole 4, and the fastening bolt 8 is tightened after the upper upright pole 3 is adjusted to a suitable height according to the height of the protective net 11.

The L-shaped buckle 2 includes an L-shaped positioning leg 201. The horizontal rod of the positioning leg 201 passes through the panel 1 and is fixed with a cylindrical limiting plate 202. A spring 203 is sleeved on the horizontal portion of the positioning leg 201 between the limiting plate 202 and the panel 1. The positioning leg 201 can rotate 360° with the axis of the limiting plate 202 as the rotation center line. The gap between the positioning leg 201 and the panel 1 can be adjusted according to the thickness of the protective net 11, and the protective net 11 is tightened by the spring 203. After the protective net 11 is inserted into the U-shaped groove 5, the positioning leg 201 is twisted to position and tighten the protective net 11.

The wing-shaped clamp includes a 匚-shaped component 7 and a fishhook-shaped clamp 6; the fishhook-shaped clamp 6 includes a J-shaped hook, and the long handle end of the hook is threadedly connected with a fastening nut; the 匚-shaped component 7 is provided with a strip slide for moving the hook; the long handle end of the hook passes through the strip slide and is connected to the fastening nut.

The specific installation steps are as follows:

Step 1: After the prefabricated beam is erected, slide the fishhook-shaped clamp 6 in the strip slide according to the position of the reserved steel bar 10. After the fishhook-shaped clamp 6 clamps the steel bar 10, the fastening nut of the fishhook-shaped clamp 6 and the wing-shaped clamps on both sides of the lower vertical rod 4 are tightened to form a triangular stable state with the triangular support frame 9.

Step 2: Loosen the fastening bolts 8 on the lower pole 4, adjust the height of the upper pole 3 according to the height of the protective net 11, and tighten the bolts 8 after adjusting to a suitable height. At this point, the erection of the protective device pole is completed;

Step 3: Pull out the positioning leg 201 away from the panel 1 and twist the positioning leg 201 upward, insert the protective net 11 into the U-shaped groove 5, and after the protective net 11 is placed stably, twist the positioning leg 201 downward to complete the positioning and tightening operation of the protective net 11. The U-shaped groove 5 is convenient for supporting the bottom of the protective net 11 on the one hand, and for splicing the protective net 11 on the other hand.

Step 4: Follow the steps 1 to 3 above to provide safety protection for the edges of the beam and complete the installation of all protective devices for the erection beam.

Step 5: After the construction is completed, the device needs to be dismantled and recycled. The on-site personnel twist the positioning leg 201 to the upward position, pull out the protective net 11 from the U-shaped groove 5 and move it to the designated stacking position, loosen the fastening bolts 8 to retract the upper upright 3, and then loosen the fastening nuts of the fishhook-type clamp 6 to remove the protective device from the reserved steel bar 10, and dismantle and recycle all the remaining protective devices in turn for turnover use.

In summary, the quick-detachable combined prefabricated beam edge protection device of the utility model is easy to install and disassemble, has good recycling and utilization performance, and solves the problems of poor enclosure effect and complicated procedures in the past. The height of the protection device can be adjusted at any time according to the height of the protection net, and the vertical pole is firmly and reliably erected, which can effectively ensure the safety performance of the edge of the erected beam body, and can be widely promoted and applied in bridges, highways, water conservancy and other projects.
