Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, and more particularly to a recyclable steel wire rope suspension bar for a pile foundation reinforcement cage. Background Art
[0002] In the traditional construction process, after the bored pile hole detection is completed, it is necessary to use lifting rods to lift and lower the steel cage, and the height of the steel cage needs to be controlled according to the actual hole depth.
[0003] Therefore, the most important parameter of traditional hangers is their length, which needs to be calculated based on the ground elevation, the pile top elevation, and the thickness of the ground wood. Then, it is necessary to ensure that the hangers are effectively connected to the steel cage. Hangers are generally welded, and most of them cannot be recycled. In addition, it is necessary to prevent the steel cage from "falling off", which places high demands on the welding quality. When the pile foundation is long and the steel cage is heavy, the hanger length and diameter are large, the lifting risk is high, and it cannot be recycled. When there are more pile foundations and the pile foundations are longer, the cost of investing in the hangers will be higher.
[0004] In summary, during the construction of traditional pile foundation steel cages, there are problems such as difficulty in controlling the length of the suspension bars, high safety risks in hoisting, inability to recycle, and large additional construction investment.
[0005] Therefore how to solve the above-mentioned technical problems just becomes the problem that the utility model faces. Utility Model Content
[0006] The present utility model aims to develop a reusable wire rope hoist during pile foundation construction, especially when installing a pile foundation reinforcement cage at a depth greater than 8m or in water depths exceeding 8m. The invention is simple to operate and reduces lifting safety risks. By using wire rope instead of steel bars, the hoisting bar does not need to be spliced and can be recycled after the concrete pouring of the reinforcement cage is completed, thus saving manpower and material resources. The hoisting bar is highly efficient and easy to use, and the switching of lifting points and working conditions is safe and reliable. The hoisting bar is accurate in length and can precisely control the elevation of the reinforcement cage.
[0007] The utility model solves the technical problem by adopting a technical solution: providing a reusable steel wire rope hanger for a pile foundation reinforcement cage, comprising two fixing rings fixedly connected to the main reinforcements on both sides of the top of the reinforcement cage, and two vertically arranged steel wire ropes respectively connected to the two fixing rings, wherein the lower side of the steel wire rope passes over the fixing rings and then extends upward;
[0008] The top end of the steel wire rope is bent downward and bound by an upper buckle assembly to form a lifting ring, and the lifting ring cooperates with the horizontal lifting beam of the lifting machinery. The steel wire ropes on both sides above the fixed ring are bound by a middle buckle assembly, and the tail end of the steel wire rope is bent downward and bound by a bottom buckle assembly to form a ring, and a shoulder pole beam is provided on the inside of the ring.
[0009] The fixing ring is in a U shape with its opening facing downward and is located inside the steel cage. The outer vertical portion of the fixing ring is fixedly connected to the inner side of the main reinforcement of the steel cage.
[0010] The upper snap assembly, the middle snap assembly and the bottom snap assembly all include a U-shaped ring, a fixing plate is sleeved between the two sides of the U-shaped ring, an arc-shaped groove that cooperates with the steel wire rope is opened at the top center of the fixing plate, and fixing nuts are threadedly connected on both sides of the U-shaped ring, and a spring sheet is provided between the fixing nut and the fixing plate.
[0011] The shoulder pole beam is made of I-beam, and the length of the shoulder pole beam is not less than twice the diameter of the pile foundation hole.
[0012] When the utility model is actually used: the steel wire rope is passed through the fixed ring, the position of the middle buckle assembly is determined by setting the distance between the top steel cage and the pile foundation hole, and then the length of the bottom buckle assembly is adjusted to the calculated length through the middle buckle group, and the middle buckle assembly is buckled, and the steel wire rope is fixed with the upper buckle assembly and the bottom buckle assembly respectively to form a lifting ring, and the upper buckle assembly is hung on the horizontal lifting beam of the lifting machinery to lift the steel cage. When the steel cage is lowered to the ring close to the wellhead, two sets of shoulder beams are used to pass through the ring, and continue to slowly lower it to the designed elevation so that the steel wire rope of the ring part is fully stressed, and then the ring is removed to complete the working condition conversion. After the concrete pouring is completed, the upper buckle assembly and the middle buckle assembly are removed, and the steel wire rope is slowly pulled out as a whole by lifting the ring, so as to realize the recycling of the steel wire rope lifting reinforcement.
[0013] The beneficial effects of the utility model are:
[0014] 1. The utility model has a simple structure and is easy to use. It can accurately control the elevation of the steel cage according to the top wellhead elevation. It is applicable to all steel cage construction, especially pile foundation construction with a burial depth greater than 8m or a water depth exceeding 8m;
[0015] 2. The steel wire rope used in the utility model can be used cyclically, thus saving costs.
[0016] 3. The utility model has less manual participation in the entire hoisting process, and the main work is the installation and removal of the buckles. It is easy to use, efficient, and saves manpower and material resources.
[0017] 4. The utility model is safe and reliable in the conversion of working conditions of lifting points of steel cage hoisting. BRIEF DESCRIPTION OF THE DRAWINGS
