Description

Technical field:

[0001] The utility model belongs to the technical field of water conservancy and hydropower engineering construction, in particular to multi-layer slipform equipment in slipform construction of hydropower stations, specifically a jack hanger device for multi-layer platform slipform. Background technology:

[0002] In the field of traditional hydropower engineering construction, the slipform equipment with large structural volume, large amount of steel bars, large amount of concrete and high construction quality requirements in the slipform construction field is no longer a single-layer slipform equipment. Instead, two-layer or more multi-layer slipform equipment with more convenient construction is adopted. However, during the construction of traditional multi-layer slipform equipment, the free height of the jack on the climbing pole is limited, resulting in a small distance between the upper and lower construction platforms of the jack, and there is no sufficient and safe construction space, resulting in great construction difficulty, imperfect technology, substandard construction quality and other problems. At the same time, the traditional climbing pole arrangement method is prone to distortion during the slipform construction process, and the slipform correction is frequent, requiring repeated adjustments, which affects the construction quality and progress. Summary of the invention:

[0003] The utility model provides a jack hanger device for a multi-layer platform slipform in view of the deficiencies in the prior art, which can effectively solve the construction problems such as narrow space between platform slipform layers, easy distortion during slipform construction, frequent slipform correction and repeated adjustment.

[0012] The jack hangers are evenly and symmetrically arranged on the entire warehouse surface.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model is provided with a jack hanger, in which a through-type jack is placed, the bottom of the jack hanger is bolted to the through-type jack base, and the upper part is bolted to the bottom of the main truss, so as to ensure that the free height of the climbing pole remains unchanged while greatly increasing the construction space.

[0015] 2. The utility model adds multiple sets of through-type jacks and climbing poles, which solves the problems of easy distortion of the climbing pole arrangement during the slipform construction process and frequent slipform correction.

[0016] 3. The utility model effectively solves the problem that the small distance between platforms during the slipform construction process limits the construction space and causes construction difficulties, and the slipform structure itself has poor torsional resistance during the slipform construction process.

[0024] See also Figure 1-Figure 3 The utility model provides a jack hanger device for a multi-layer platform slipform, which includes a jack hanger 1, a through-type jack 2, a steel plate base 4, a climbing rod 6, a template truss 8, a main truss 9, a template 10, and a column 11. The jack hanger 1 is a frame structure, which is vertically installed below the main truss 9 of the multi-layer slipform equipment and above the template truss 8. The jack hanger 1 is evenly and symmetrically arranged on the entire warehouse surface. The main skeleton of the jack hanger 1 is welded by angle irons. The main skeleton of the jack hanger 1 is surrounded by oblique reinforcements 3. The top of the main skeleton of the jack hanger 1 is provided with hanger bolt holes 5. The top of the jack hanger 1 is fixedly connected to the main truss 9 by bolts. Columns 11 are symmetrically arranged on both sides of the jack hanger 1. The columns 11 are installed between the template truss 8 and the main truss 9 to connect the main truss 9 and the template truss 8 into a whole. A steel plate base 4 is provided at the bottom of the jack hanger 1, and the steel plate base 4 is provided with bolt holes 7. The steel plate base 4 is connected to the jack hanger 1 by bolts. Multiple groups of through-type jacks 2 are symmetrically and evenly arranged in the frame structure of the jack hanger 1 and on the steel plate base 4. Through holes matching the diameter of the climbing rod 6 are provided at the corresponding positions of the steel plate base 4 and the through-type jacks 2. The lower end of the climbing rod 6 corresponding to the through-type jack 2 is buried in the concrete 12, and the upper end passes through the corresponding through-type jack 2. The corresponding through-type jack 2 is fixed in the jack hanger 1. When the through-type jack 2 climbs upward along the climbing rod 6 under hydraulic drive, it drives the entire slipform equipment to slide upward. In this embodiment, 2 to 3 groups of through-type jacks 2 are symmetrically and evenly arranged in the frame structure of the jack hanger 1.

[0025] During the construction process, due to the addition of a jack hanger 1, the original direct connection method between the main truss 9 and the steel plate base 4 of the through-type jack 2 is changed to a direct connection between the main truss 9 and the upper part of the jack hanger 1, and the main body height of the jack hanger 1 is increased, thereby increasing the construction space. At the same time, compared with the traditional design, multiple groups of symmetrically and evenly arranged through-type jacks 2 and climbing poles 6 are used, which greatly increases the stability of the entire platform.
