Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of engineering construction, and in particular to a welding positioning device for steel cages. Background Technology
[0002] The existing welding process for steel cages typically involves using molds to bend the steel bars required for the inner support circle into a circle and then fixing them by welding. The main reinforcement bars of the steel cage are then evenly arranged on the ground. Construction workers then hold the inner support circles and weld them one by one to the two adjacent sets of main reinforcement bars at the edge. After that, the multiple sets of welded inner support circles are rotated to the two sets of main reinforcement bars that are welded to them, so that the multiple sets of inner support circles are rotated to the next adjacent set of unwelded main reinforcement bars for welding connection, until all the main reinforcement bars of the entire steel cage are welded, forming the main body of the cylindrical steel cage.
[0003] The existing Chinese utility model patent with application number CN202022495496.8 relates to a steel cage welding positioning device, which includes a positioning frame, gear rod, base frame, support leg, motor, base and fixing column, etc., and can bind steel bars of different diameters.
[0004] However, in actual use, the device itself is large and difficult to move. Furthermore, the process of inserting the steel bar into the device requires at least two workers to lift and insert the steel bar simultaneously, which increases labor costs and time. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a steel cage welding positioning device that provides support for the main reinforcement bars by a positioning device and limits the two ends of the main reinforcement bars, controls the spacing between adjacent main reinforcement bars by a connecting device, and adjusts the spacing between adjacent main reinforcement bars by an adjusting device, thereby improving the practicality of the device.
[0006] This utility model discloses a welding positioning device for reinforcing cages, comprising a positioning device, a connecting device, and an adjusting device. The connecting device is installed on the positioning device, and the adjusting device is installed on the connecting device. The positioning device provides support for the placed main reinforcing bars and limits the two ends of the main reinforcing bars. The connecting device controls the spacing between adjacent main reinforcing bars, and the adjusting device adjusts the spacing between adjacent main reinforcing bars, thereby improving the practicality of the device.
[0007] Preferably, the positioning device includes an L-shaped support plate, insert strips, connecting columns, support grooves, and limiting holes. Two sets of L-shaped support plates are placed on the ground. Multiple sets of insert strips are evenly arranged on the L-shaped support plates, and the multiple sets of insert strips on the two sets of L-shaped support plates can be inserted into their respective gaps. Multiple sets of connecting columns are placed on the L-shaped support plates. One end of the connecting column is connected to the support groove, and the middle of the connecting column is provided with a limiting hole, which communicates with the support groove. The multiple sets of connecting columns are evenly placed on the L-shaped support plates. Then, the two ends of the main reinforcement are placed on the support grooves of the multiple sets of connecting columns. After the main reinforcement is placed, the two sets of L-shaped support plates are pushed to further cross-connect the insert strips on the two sets of L-shaped support plates, so that the two ends of the main reinforcement are inserted from the support grooves into the limiting holes, limiting the position of the two ends of the main reinforcement. The insert strips provide auxiliary support for the main body of the main reinforcement, reducing the downward bending of the middle of the horizontally placed main reinforcement due to its own weight, which would affect the normal welding of the inner ring, and improving the practicality of the device.
[0008] Preferably, the connecting device includes a rotating sleeve, a bearing, a main connecting frame, two side connecting frames, and sliding connecting rods. A rotating sleeve is provided at one end of the main connecting frame, and the rotating sleeve is fitted onto the middle of the connecting column via the bearing. A set of two side connecting frames are connected to the front and rear parts of the connecting column, respectively. Two sets of sliding connecting rods are connected between the two sets of side connecting frames. The two sets of sliding connecting rods pass through the interior of the main connecting frame connected to adjacent connecting columns and can move within the main connecting frame. The main connecting frame and the two side connecting frames connect adjacent sets of connecting columns, thereby facilitating the rolling process of the inner ring and the main rib during welding, reducing the force displacement of the main rib during rolling, and improving the practicality of the device.
[0009] Preferably, the device also includes strip-shaped limiting holes and sliding limiting protrusions. A set of strip-shaped limiting holes is provided on the upper and lower end faces of the main connecting frame, and a set of sliding limiting protrusions is provided on the upper and lower end faces of the sliding connecting rod. The sliding limiting protrusions on the upper and lower sides can be inserted into the strip-shaped limiting holes at the upper and lower parts of the main connecting frame, respectively. The strip-shaped limiting holes and sliding limiting protrusions work together to limit the position adjustment process between the main connecting frame and the two side connecting frames, thereby keeping the positions of both ends of all main reinforcing bars uniform. This ensures that the reinforcing bars at both ends of the welded steel cage are flush, reducing the need for subsequent repairs to the reinforcing bars at both ends of the steel cage and improving the practicality of the device.
[0010] Preferably, the device also includes a scale bar and a scale pointer. The scale bar is provided on the upper surface of the main connecting frame, and the scale pointer is provided on the upper surface of the sliding limit protrusion. The scale pointer and scale bar facilitate the operator to quickly adjust the spacing between the main reinforcement bars, thereby controlling the diameter of the steel cage and improving the practicality of the device.
[0011] Preferably, the adjusting device includes a screw, a nut, and a rotating head. A nut is provided between two sets of sliding connecting rods. A through hole is provided on the side of the sliding connecting rod to connect with the inner hole of the nut. A screw is installed in the main connecting frame. One end of the screw is connected to the main connecting frame body through a bearing. The other end of the screw passes through the sliding connecting rod and is connected to the nut, extending to the outside of the main connecting frame. A rotating head is provided on the end of the screw located on the outside of the main connecting frame. By rotating the rotating head, the screw is driven to rotate. The rotating screw and the nut cooperate to precisely adjust the cross distance between the main connecting frame and the two side connecting frames, that is, to adjust the distance between adjacent main bars, and at the same time to adjust the diameter of the main body of the steel cage. Moreover, the distance between adjacent connecting columns after adjustment is not easily changed during repeated use, which improves the stability and practicality of the device.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the positioning device provides support for the main reinforcement bars and limits the two ends of the main reinforcement bars; the connecting device controls the spacing between adjacent main reinforcement bars; and the adjusting device adjusts the spacing between adjacent main reinforcement bars, thereby improving the practicality of the device.

Then, the ends of multiple sets of main reinforcing bars are placed on the support grooves 4 of the side connecting columns 3. Next, the L-shaped bearing plates 1 are pushed laterally, causing them to push the connecting columns 3 so that the ends of the main reinforcing bars are inserted into multiple sets of limiting holes 5. Then, the rotating head 17 is rotated to adjust the spacing between the main reinforcing bars. Afterward, the operator sequentially welds multiple sets of inner supporting circles onto the two outermost sets of main reinforcing bars. After welding, the device is flipped so that the inner supporting circles are rotated to support the second and third sets of main reinforcing bars.
