Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge wet joint construction equipment, in particular to a folding hanging basket for bridge wet joint construction. Background Art
[0002] Wet joints are mainly used to connect prestressed concrete beams. During the construction process, prestressed concrete beams are usually prefabricated in blocks and then cantilevered into large-span continuous beams. In order to connect these beams into a whole, cast-in-place concrete is used to fill the joints between the beams. This joint is called a wet joint in the construction industry. The diaphragm refers to a transverse member located between the main beams of the bridge. Its function is to increase the rigidity and stability of the bridge, separate the main beams of the bridge, and enable the bridge deck to withstand vehicle loads and transfer them to the main beams. The construction process of the diaphragm directly affects the safety and service life of the bridge. After the precast beams are hoisted onto the cap beams and laid, wet joints are formed between the precast beams. The diaphragms between the wet joints are located under the precast beams and need to be reinforced and installed with formwork.
[0003] The existing hanging baskets have the following technical problems: 1. Since the bridge height is relatively high and the bridge is often laid above the river and between the valleys, the ground terrain under the bridge is relatively complex. Therefore, it is not easy to set up equipment under the bridge to construct the diaphragm, and a construction equipment that can be hung between the prefabricated beams is needed. 2. The width of the wet joint is relatively narrow. After the prefabricated beams are hoisted and laid, the steel bars between the wet joints affect the bottom of the hanging basket, and the hanging basket needs to be folded and scaled before it can be lowered from between the wet joints. 3. Due to the different sizes of prefabricated beams, the height of the diaphragm from the upper surface of the beam is also different, so the hanging basket needs to be able to adjust the up and down height to meet the requirements of the diaphragm construction. The existing hanging basket has poor adaptability and cannot achieve multiple turnovers. At the same time, there is no safety ladder, which makes it inconvenient for workers to go up and down, and the construction safety cannot be guaranteed. Utility Model Content

[0005] The technical solution of the utility model to achieve the above-mentioned purpose is a folding hanging basket for bridge wet joint construction, comprising a first bracket, a second bracket, a first support arm, a second support arm and a base. The two ends of the base are hinged with the first bracket and the second bracket through a pin shaft, the upper end of the first bracket is telescopically connected to the first support arm and fixed by bolts, the upper end of the second bracket is telescopically connected to the second support arm and fixed by bolts, a number of threaded holes are arranged at equal intervals on the first bracket and the second bracket, and corresponding threaded holes are also arranged on the first support arm and the second support arm, and the bolts are passed through the corresponding threaded holes on the first bracket and the first support arm and the second bracket and the second support arm, and then fixed by nuts. Ladder rods are arranged at equal intervals from top to bottom on the first support arm and / or the second support arm, and the upper ends of the first support arm and the second support arm are provided with hanging basket cross arms, and the two hanging basket cross arms are respectively hung on the edges of the two prefabricated beams and extend in the direction away from the center of the expansion joint. The upper ends of the first bracket and the second bracket are both provided with a safety rope, one end of the safety rope is connected to the first bracket and the second bracket, and the other end of the safety rope is provided with a rope buckle. The safety rope is stretched upward so that the rope buckle is hung on the steel bars on the surface of the prefabricated beam and fixed.
[0006] A further solution of the utility model is that support rods are provided on the two hanging basket cross arms. The support rods, firstly, provide extended support arms when the wet joint is wider and the distance between the two hanging basket cross arms is smaller, so as to prevent the hanging basket from falling; secondly, increase the length of the force arm and improve the supporting area of the hanging basket cross arm, so as to make the supporting strength of the hanging basket higher, prevent the hanging basket from shaking, and improve safety.
[0007] A further solution of the utility model is that cross bars are arranged at equal intervals at the lower parts of the first bracket and the second bracket, and the cross bars are used as side fences and improve the strength of the first bracket and the second bracket.
[0008] A further solution of the utility model is that hinged connecting rods are evenly spaced on both sides of the lower part between the first bracket and the second bracket, and the connecting rods are also used as side fences and improve the strength between the first bracket and the second bracket.
[0009] A further solution of the utility model is that the two ends of the base are connected to the first bracket and the second bracket through a pin shaft, and the two ends of the connecting rod are hinged to the first bracket and the second bracket through a pin shaft.
[0010] A further solution of the utility model is that a patterned plate is provided on the upper surface of the base to increase friction and prevent workers from slipping.
[0011] According to the above technical solution, the first support arm and the first bracket, the second support arm and the second bracket are first adjusted to the same height, and then fixed with bolts. Then, the hanging basket is folded and scaled, and the width between the first bracket and the second bracket, the first support arm and the second support arm is shortened by lifting the first bracket or the second bracket. Next, the folded hanging basket is lowered to the bottom of the prefabricated beam through the expansion joint, and then the rope buckle of the wire rope is held by hand. After opening the hanging basket, the rope buckle is hung on the embedded steel bars on the upper surface of the prefabricated beam.
