Description

Technical Field

[0001] The invention belongs to the technical field of construction of special-shaped formworks for cantilever-cast beams, and relates to a lateral displacement device for a hanging basket formwork. Background Art

[0002] With the vigorous development of China's infrastructure construction, construction technologies are also constantly advancing. The cantilever-cast construction technology for continuous beams has become increasingly mature. However, when the large-span cantilever-cast beam is designed into a combined structure of an arch beam, the concrete main body of the continuous beam increases the hanging point structure, which increases the difficulty of the cantilever-cast construction of the continuous beam. Especially when the beam body spans existing railways and highways, the installation and construction of the beam body formwork are extremely difficult.

[0003] Generally, the installation and construction of the outer formwork of the cantilever-cast beam are carried out synchronously with the movement of the hanging basket, and the outer formwork is fixed by using the outer guiding beam of the hanging basket. Before the hanging basket moves, the outer formwork is lowered by a certain height, and the outer formwork moves forward synchronously with the outer guiding beam. After the hanging basket moves in place, the outer formwork is lifted upward and installed and fixed. If the continuous beam body is not a regular box chamber structure and has some special structures, the outer formwork needs to be removed after the hanging basket moves forward and reinstalled according to the position of the special structure. However, since the existing lines below many projects cannot be closed, the conditions for using ordinary lifting machinery for formwork construction are not available. By referring to the construction experience at home and abroad in the past, there are two methods for such construction to choose from, namely, using a lifting device with a large enough working radius and hoisting construction on the beam with a general lifting device. Since this project spans existing important railway main lines, highways and national roads, the safety during the construction process is very important. There are many potential safety hazards in the hoisting construction on the beam itself. In the process of cantilever-cast construction of continuous beams, extremely high requirements are placed on the weights at both cantilever ends, and the loads at both ends need to be balanced. If there is a slight mistake during the hoisting operation, it will cause serious damage to the beam body, and even the beam body may overturn. Moreover, serious safety hazards will be caused to the existing important railway main lines, highways and national roads below during the hoisting process, and hoisting operations are prohibited without the permission of the relevant departments. Therefore, the safety of the two construction methods cannot be satisfied. Summary of the Invention

[0023] See Figure 2 , the mobile trolley 3 adopted in the present invention includes a vehicle body 31 and steel rollers 32 placed on the side of the vehicle body; the steel rollers 32 are placed on the upper surface of the lateral working platform 2 and slide freely on the upper surface of the lateral working platform 2; the vehicle body 31 is a frame structure formed by welding two channel steels facing each other. The mobile trolley 3 further includes a rack 33 and a gear 34 meshing with the rack 33; the gear 34 is placed on the lateral working platform 2; the rack 33 is placed at the bottom of the vehicle body 31; the steel rollers 32 are placed on the upper surface of the lateral working platform 2 and slide freely on the upper surface of the lateral working platform 2 along the axial direction of the rack 33. The mobile trolley 3 further includes a U-shaped groove 35 provided on the lateral working platform 2 and tangent to the rotation track of the gear 34; a stop rod is provided in the U-shaped groove 35.

[0024] The lateral working platform 2 includes a bottom channel steel 21 and a top channel steel 22 placed on the top of the bottom channel steel 21; the gear 34 is placed on the top channel steel 22, and the steel rollers 32 are placed on the upper surface of the top channel steel 22 and slide freely on the upper surface of the top channel steel 22 along the axial direction of the rack 33. Both the bottom channel steel 21 and the top channel steel 22 are formed by welding two channel steels back to back.

[0025] The lateral adjusting rod 4 includes a bottom built-in rod, a top built-in rod, and a sleeve; both ends of the sleeve are respectively sleeved outside the bottom built-in rod and the top built-in rod and are respectively connected to the bottom built-in rod and the top built-in rod through reverse threads; the bottom built-in rod is movably arranged on the mobile trolley 3; the top built-in rod is movably arranged at a vertex of the triangular stabilizer 5. A rotating handle is provided on the outside of the sleeve.

[0026] The lateral working platform 2 is fixed to the hanging basket cross beam 1 by welding. The top channel steel 22 consists of two back-to-back channel steels, with a total of 2 groups, vertically placed on the bottom channel steel 21. The distance between the two back-to-back channel steels is slightly greater than the width of the gear or rack. The moving trolley is welded by two facing channel steels, with end plates on both sides. At the same time, holes are opened on both sides. Through the pin shaft, there is a pair of steel rollers on it. At the same time, a rack is welded at the exact center of the bottom. A gear is designed at the exact center corresponding to the rack. The gear is also pinned to the center of the double web of the channel steel through the pin shaft. A U-shaped groove is designed at the center of the double web on the side close to the outer formwork. When the gear moves into place (the outer formwork is in the state of being separated when moved outwards; the inner formwork is in the state of concrete pouring construction when moved inwards), a screw is used to fix the gear in the groove. By turning the handle on the sleeve, the rods inside both ends of the sleeve contract simultaneously. Because the lowest edge of the triangular stabilizer is pinned (the upper end is also pinned to the adjusting device), at this time, the triangular stabilizer will rotate outwards along the pin shaft. And the outer formwork is fixed on the triangular stabilizer, so it will drive the formwork to rotate, achieving the purpose of demoulding. Both ends of the adjusting device are welded to the moving trolley through the ear plates, and the other end is welded to the triangular stabilizer through the ear plates, and the connection is achieved through the pin shaft. When the demoulding is completed, by turning the gear outwards, the movement of the entire outer formwork is realized, achieving the outward movement of the entire formwork. It can easily enter the forward movement of the hanging basket, driving the movement of the entire formwork system.
