Description

Technical Field

[0001] This invention relates to the technical field of circular template positioning, and in particular to a circular template support docking device and its usage method. Background Technology

[0002] Currently, nuclear power plants and hydroelectric power plants contain various sizes of circular intake channels, culverts, and other structures. The construction of these structures requires the erection of circular formwork and the pouring of concrete on the outside to shape them. Because the circular formwork is relatively thin, the assembly process is time-consuming and requires multi-dimensional adjustments. This is especially true for large-diameter formwork, which demands more manpower. Furthermore, during concrete pouring, the assembly points of the circular formwork are prone to misalignment, leading to quality defects such as unevenness in the final concrete structure. Subsequent grinding and repair require significant manpower, affecting the final appearance and overall quality of the concrete structure. Summary of the Invention

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0027] The structures, proportions, and sizes illustrated in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention.

[0029] Each pair of adjacent arc-shaped channel steels 2 are installed by angle steels 3, and several arc-shaped channel steels 2 surround to form a circular structure, which is located on the inner wall of the circular template 1; several first steel pipes 4 are arrayed and installed on the inner wall of the circular structure; both ends of several second steel pipes 5 are respectively installed on a first steel pipe 4 through a top support 10; a primary keel 6 is installed at one end of the circular template 1, and the one end of the circular template 1 is connected to the outside to form a reserved installation position 11; one end of the side wing plate 7 is installed at the reserved installation position 11, and the side wing plate 7 is installed on the side wall of the secondary keel 6 by screws; the other end of the side wing plate 6 is provided with a bolt hole.

[0030] In practical use, the arc-shaped channel steel 2 serves as the main roundness control device. A first steel pipe 4, a second steel pipe 5, and a top support 10 are installed inside the arc-shaped channel steel 2 for support, preventing deformation of the circular template 1 during transportation, docking, and concrete pouring. When installing the secondary keel 6, the secondary keel 6 is offset from the circular template 1 at a certain distance at the joint position. In this device, the offset is 30mm, which is the reserved installation position 11. Side wing plates 7 are installed at the reserved installation position 11 and fixed to the secondary keel 6 with iron nails 12. After fixing, holes are drilled in the side wing plates 7. Finally, the bottom ends of the two circular templates 1 are placed on the same straight line, and the side wing plates 7 on the two circular templates 1 are tightened. Fine adjustments are made using fastening screws 9 before installation. Furthermore, the arc-shaped channel steel 2, angle steel 3, first steel pipe 4, and second steel pipe 5 in this device form a support device for the circular template, while the secondary keel 6 and side wing plates 7 form a docking device for the circular template.

[0031] In addition to the above, the present invention also has the following embodiments:

[0032] Furthermore, a circular template support and docking device is provided, wherein a plurality of second steel pipes 5 form a star-shaped structure, and the middle parts of the plurality of second steel pipes 5 are fixedly connected. Specifically, the star-shaped structure provides better support for the circular template 1.

[0033] Furthermore, a circular template support docking device is provided, wherein the bolt holes 8 are elliptical. Specifically, the elliptical bolt holes facilitate adjustment of deviations during subsequent installation of the fastening bolts 9.

[0034] Furthermore, a circular template support docking device is provided, wherein the side wing plate 7 is arc-shaped. Specifically, the arc-shaped side wing plate 7 improves the docking effect of the two circular templates.

[0036] Step 1: Install the circular control support device; splice several arc-shaped channel steels 2, with each pair of adjacent arc-shaped channel steels 2 connected by angle steels 3 and fixed with bolts; and during this process, the arc-shaped channel steels 2 need to be trial-assembled to ensure the roundness requirements of the circular template 1.

[0037] Step 2: Install the secondary keel 6; Install the secondary keel 6 at one end of the circular template 1, and the secondary keel 6 and the circular template 1 are staggered to form a reserved installation position 11. Then install the first steel pipe 4 and the second steel pipe 5.

[0038] Step 3: Install side wing plate 7; Install side wing plate 7 in the reserved installation position 11, and install side wing plate 7 and secondary keel 6 with screws. Then, make bolt holes 8 on side wing plate 7; In order to prevent cement slurry from seeping into the interior of circular module 1 during concrete pouring, a circle of double-sided tape can be pasted on side wing plate 7 to prevent slurry leakage.

[0039] Step 4: Connecting the circular templates 1; transport the assembled circular templates 1 to the installation site and use a crane for transportation and assembly. During assembly, place the bottoms of the two circular templates 1 on the same straight line and ensure that the side wing plates 7 are tightly attached.
