Description

Technical Field

[0001] The utility model relates to the field of hydropower engineering cavern concrete lining, in particular to a hydraulic lining trolley template seam caulking device. Background Art

[0002] Needle beam trolleys are often used in hydraulic tunnel projects for concrete lining support construction. Needle beam trolleys are generally customized by manufacturers, but the same project often has caverns with different diameters. The same set of needle beam trolleys cannot meet the needs of all caverns. During the trolley modification process, there are situations where the template gap is too large; or due to the processing precision, the needle beam trolley template gap is large after on-site installation, and the trolley template gap must be filled.

[0003] At present, most projects use foam glue combined with wooden formwork caulking strips to caulk the joints, but there are often problems such as poor flatness, serious leakage, and large displacement during pouring, which leads to unsatisfactory gap treatment of the needle beam trolley and poor appearance quality of the concrete. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in view of the above existing problems, a hydraulic lining trolley template seam caulking device is provided.

[0005] The technical solution adopted by the utility model is: a hydraulic lining trolley template seam caulking device, characterized in that it includes:

The pressure plate is used to fix the angle formed by the wing plates after being connected and unfolded.

[0008] Through the above-mentioned technical means, multiple rotatably connected wing plates can adjust the angle formed by the entire wing plate assembly, and the angle of the wing plate assembly can be adjusted according to the angle of the outer arc surface of the trolley template, so that the wing plate assembly can fit the outer surface of the trolley template while caulking the seams of the trolley template, and is connected to the inner side of the wing plate assembly by a pressure plate. On the one hand, the pressure plate is used to fix the connection angle formed by the wing plate assembly, and on the other hand, the pressure plate is used to provide sufficient supporting strength for the wing plate assembly.

[0009] In some embodiments, the wing plate assembly includes a first wing plate and a second wing plate, and the connecting side edges between the first wing plate and the second wing plate are staggered with through screw holes. After the first wing plate and the second wing plate are spliced, the through screw passes through the corresponding through screw holes to achieve rotational connection.

The wing plate assembly 1 includes a plurality of rotatably connected wing plates. The connection angle formed by the plurality of wing plates is adjusted based on the curvature of the outer surface of the trolley template, so that when the wing plate assembly 1 caulks the trolley template seam, the two sides of the wing plate assembly 1 are respectively connected to the trolley template surface on both sides of the trolley template seam. The pressure plate 2 is arranged on the inner side of the wing plate assembly 1 facing the trolley template, and the two ends of the pressure plate 2 abut the trolley template on both sides of the trolley template seam. The pressure plate 2 is flexibly cut and processed, and the setting width of the pressure plate 2 is the width of the trolley gap. The pressure plate 2 is used to fix the angle formed by the wing plate assembly 1 after it is connected and unfolded, so as to avoid the connection angle of the wing plate assembly 1 changing due to the pressure on the outside, and the pressure plate 2 can provide sufficient support strength for the wing plate assembly 1.

[0030] In some embodiments, such as Figure 2 As shown, the wing panel assembly 1 includes a first wing panel 3 and a second wing panel 4. The connecting side edges between the first wing panel 3 and the second wing panel 4 are staggered with through screw holes 5. After the first wing panel 3 and the second wing panel 4 are spliced, the through screws 6 pass through the corresponding through screw holes 5 to achieve rotational connection, so that the wing panel assembly can be easily assembled and disassembled.

[0031] Furthermore, the edge sides of the first wing plate 3 and the second wing plate 4 away from the connection are provided with small-angle chamfers to facilitate fitting to the trolley template.

[0032] Furthermore, the inner surfaces of the first wing plate 3 and the second wing plate 4 are both curved surfaces close to a plane, and the outer surfaces of the first wing plate 3 and the second wing plate 4 are curved surfaces with the same curvature as the outer surface of the trolley template.

Specifically, in this embodiment, the bolt holes 8 are provided at intervals of 50 cm to 100 cm.

[0034] In some embodiments, foam glue is provided in the gap between the pressure plate 2 and the trolley template.

[0035] The first wing plate 3 and the second wing plate 4 are used to caulk the seams of the trolley formwork, and the pressure plate 2 is used to fix the connection angle of the first wing plate 3 and the second wing plate 4 after the connection, and the pressure plate 2 provides a certain degree of supporting strength for the wing plate assembly 1, so that the first wing plate 3 and the second wing plate 4 have a certain strength, which can reduce the risk of displacement and deformation of the formwork. The device reduces the difficulty of modifying the size deviation of the trolley formwork to a certain extent, solves the problems of leakage of mortar in the gaps of the trolley formwork and misalignment of the joints, improves the appearance quality of the concrete, and saves the cost of later defect treatment.
