Description

Technical Field

[0001] The present application relates to the technical field of water conservancy project construction, and in particular to an auxiliary steel strand tensioning stand. Background Art

[0002] In the shield tunnel lining construction, the standard bin of ring-anchor prestressed concrete has 23 anchor slots, and each anchor slot has four steel strands wrapped around for tensioning. The steel strands need to be tensioned using a tensioning machine, but the problem is that the machine cannot be fixed and manpower is needed to fix them, which consumes a lot of cost and occupies the space of the roadway, affecting the construction efficiency. At the same time, during the tensioning process of the steel strands, if there is looseness or incomplete engagement between the clip and the steel strand plate, and the tensioning force applied by the tensioning machine is too large, exceeding the bearing capacity of the clip, it will cause the clip to loosen and fall off when the equipment is running.

[0020] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0021] Example 1

[0022] An auxiliary steel strand tensioning stand comprises a triangular support 2, a connecting rod 4, and a protective plate 3. The triangular support 2 comprises two tripods and three crossbars. The tripods are arranged in a right triangle structure, with the two tripods arranged in parallel and the three end points connected by the crossbars. The hypotenuse of the tripod is tangent to the curved surface of the tunnel, and the crossbar is longer than the width of the anchor slot 5. The triangular support 2 is erected directly above the anchor slot 5.

[0023] Mounting rods 1 are connected to the two horizontal bars at the top of the tripod 2. Mounting rods 1 are used to hoist the tensioning device. During use, the tensioning device is fixed to the mounting rods 1 using a hand chain hoist, which adjusts the tensioning device's position. The tensioning device is directly connected to the steel strands within the anchor slots 5. The tensioning gantry is suspended from the anchor slots 5 in the appropriate position, ensuring that the tensioning device and the steel strands are aligned at the same cross-section and angle, preventing the device from shaking during the tensioning process.

[0024] The plug-in rods 4 are connected to both ends of the bottom cross bar respectively. The plug-in rods 4 are "L-shaped" structures, including a transverse rod and a vertical rod. The transverse rod is connected to the transverse rod, and the vertical rod is arranged perpendicular to the transverse rod. A plug-in slot is opened on the vertical rod, and a magnetic strip is arranged in the slot. During the tensioning process, the protective plate 3 is inserted into the plug-in slot to form protection to prevent the clip from splashing.

[0025] Example 2:

[0026] An auxiliary steel strand tensioning stand comprises a triangular support 2, a connecting rod 4, and a protective plate 3. The triangular support 2 comprises two tripods and three crossbars. The tripods are arranged in a right triangle structure, with the two tripods arranged in parallel and the three end points connected by the crossbars. The hypotenuse of the tripod is tangent to the curved surface of the tunnel, and the crossbar is longer than the width of the anchor slot 5. The triangular support 2 is erected directly above the anchor slot 5.

[0027] Mounting rods 1 are connected to the two horizontal bars at the top of the tripod 2. Mounting rods 1 are used to hoist the tensioning device. During use, the tensioning device is fixed to the mounting rods 1 using a hand chain hoist, which adjusts the tensioning device's position. The tensioning device is directly connected to the steel strands within the anchor slots 5. The tensioning gantry is suspended from the anchor slots 5 in the appropriate position, ensuring that the tensioning device and the steel strands are aligned at the same cross-section and angle, preventing the device from shaking during the tensioning process.

[0028] Connecting rods 4 are connected to each end of the bottom crossbar. These rods consist of a first rotating rod and a second rotating rod pivotally connected to the first. The first rotating rod is pivotally connected to the crossbar, while the second rotating rod has a slot housing a magnetic strip. During off-peak hours, the rods 4 can be retracted by folding the first and second rotating rods, without disrupting equipment installation and commissioning. During tensioning, the rods 4 are lowered, allowing the protective plate 3 to fit into the slot to protect them from splashing.
