Description

Technical Field

[0001] This application relates to the field of precast steel cage technology, specifically to a positioning and marking device for steel cage stiffening hoops. Background Technology

[0002] A steel cage is a prefabricated building material made of welded steel bars. It is commonly used in the construction of pile foundations, bridge and culvert foundations and high-rise building foundations. It combines with concrete pouring to bear tensile force and make up for the insufficient tensile strength of concrete.

[0003] A steel reinforcement cage typically consists of multiple vertical main bars and multiple stiffening hoops welded to each main bar. Before the stiffening hoops are connected to the main bars, the connection positions need to be marked on each stiffening hoop. Usually, a tape measure is used to roughly measure and mark the positions. However, this method is affected by human factors, resulting in uneven spacing of the marking positions. If the same marking position of two adjacent stiffening hoops is misaligned, it can easily lead to bending of the main bars after welding, affecting the forming quality of the steel reinforcement cage. Utility Model Content

This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0026] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0027] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0028] See Figures 1-6As shown, the positioning and marking device for the reinforcing cage stiffener 200 provided in this application includes a vertical stacking assembly 10 and a chalk line 20. The vertical stacking assembly 10 is used for stacking multiple stiffeners 200 sequentially in the vertical direction. The chalk line 20 is used to mark lines on the multiple stacked stiffeners 200 in a chalk line manner to ensure that the marked lines on each stiffener 200 are not misaligned, thereby improving the welding quality of the subsequent main reinforcement and the stiffeners 200.

[0029] In this embodiment, the vertically stacked assembly 10 is provided with a plurality of first limiting portions 111 and a plurality of second limiting portions 131 around its circumference. The plurality of first limiting portions 111 and the plurality of second limiting portions 131 are respectively aligned one-to-one in the vertical direction. In other words, the aligned first limiting portions 111 and second limiting portions 131 are in the same vertical direction. The ink fountain 20 is rotatably connected to the top center of the vertically stacked assembly 10. The ink line 21 of the ink fountain 20 can be sequentially limited by the aligned first limiting portions 111 and second limiting portions 131 for use in drawing lines on each stiffening hoop 200 (e.g., ...). Figure 6 As shown in the figure, lines are drawn on each stiffening hoop 200. The drawn lines are the markings on each stiffening hoop 200. Each marking can be on the same straight line on each stiffening hoop 200. When the stiffening hoop 200 is welded to the main reinforcement, the main reinforcement can be prevented from bending, thereby improving the forming quality of the steel cage.

[0030] See Figure 1 , Figure 5 and Figure 6 As shown, a plurality of first limiting portions 111 are arranged circumferentially around the top side of the stacked assembly, and a plurality of second limiting portions 131 are arranged circumferentially around the bottom side of the stacked assembly. In a preferred embodiment, the plurality of first limiting portions 111 and the plurality of second limiting portions 131 are arranged at equal intervals between each pair. Of course, in other embodiments, the intervals between each pair may not be equal, depending on the actual needs.

[0031] See Figures 1-6 As shown, the vertically stacked assembly 10 includes a base 11, a positioning frame 12, and a top cover 13. The positioning frame 12 is arranged vertically, with its bottom side connected to the base 11 and its top side connected to the top cover 13. Multiple first limiting parts 111 are disposed on the top cover 13, and multiple second limiting parts 131 are disposed on the base 11. The positioning frame 12 is used to limit the multiple stiffening hoops 200 in the vertical direction to ensure that the stiffening hoops 200 are stacked sequentially. The base 11 is used to support the sequentially stacked stiffening hoops 200, and the ink fountain 20 is rotatably mounted in the middle of the top cover 13.

[0032] To facilitate the assembly of the base 11 and top cover 13 with the positioning frame 12, in this embodiment, the positioning frame 12 has a plurality of top side positioning posts 121 on its top side and a plurality of bottom side positioning posts 122 on its bottom side. The base 11 also has a plurality of bottom side positioning holes 112, and the top cover 13 also has a plurality of top side positioning holes 132. When connecting the top cover 13 with the positioning frame 12, the plurality of top side positioning posts 121 on the positioning frame 12 are respectively positioned and inserted into the plurality of top side positioning holes 132 on the top cover 13. When connecting the base 11 with the positioning frame 12, the plurality of bottom side positioning posts 122 on the positioning frame 12 are respectively positioned and inserted into the plurality of bottom side positioning holes 112 on the base 11, so as to facilitate quick assembly.

[0033] In one embodiment, a rotating shaft 133 is provided in the middle of the top cover 13, and the ink fountain 20 is provided with a rotating shaft hole 22. The ink fountain 20 is rotatably mounted on the rotating shaft 133 through the rotating shaft hole 22, wherein the ink fountain 20 can rotate 360° around the axis of the rotating shaft 133.

[0034] In this application, the first limiting part 111 is a limiting groove or a limiting post, and the second limiting part 131 is a limiting post or a limiting groove. In this embodiment, the first limiting part 111 is a limiting groove, and the second limiting part 131 is a limiting post. The ink line 21 of the ink fountain 20 is pulled vertically from top to bottom and is locked in the limiting groove. The free end of the ink line 21 is limited by the limiting post aligned with the limiting groove by means such as winding. Then, by pulling the ink line 21, the ink on the ink line 21 is splashed onto the multiple stiffening hoops 200 stacked in sequence, so that each stiffening hoop 200 can be marked with a line.

[0035] In summary, in the reinforcing cage stiffener positioning and marking device provided in this application, the ink line of the ink fountain can be sequentially limited by the first and second limiting parts that are aligned one-to-one, so as to mark the lines on each stiffener. The drawn lines are the markings on each stiffener, and each marking can be on the same straight line on each stiffener. When the stiffener is welded to the main reinforcement, the bending of the main reinforcement can be avoided, thereby improving the forming quality of the reinforcing cage.

[0036] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the concept of this invention.
