Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a steel bar positioning structure for building construction. Background Art

[0002] Rebar refers to steel used in reinforced concrete and prestressed concrete. Its cross-section is round, sometimes square with rounded corners. It includes plain, ribbed, and twisted bars. Rebar for reinforced concrete refers to straight bars or coils used for concrete reinforcement. It comes in two shapes: plain and deformed. Delivered in straight and coiled form. Plain round bars are essentially small round bars and coils made from ordinary low-carbon steel. Deformed bars are ribbed on the surface, typically with two longitudinal ribs and evenly spaced transverse ribs along the length. Transverse ribs can be spiral, herringbone, or crescent-shaped. The nominal diameter is expressed in millimeters. The nominal diameter of a deformed bar is equivalent to that of a plain round bar of the same cross-section. The nominal diameter of rebar ranges from 8 to 50 mm, with recommended diameters of 8, 12, 16, 20, 25, 32, and 40 mm. Steel grades include 20MnSi, 20MnV, 25MnSi, and BS20MnSi. Rebar primarily withstands tensile stress in concrete. Deformed steel bars, due to their ribs, have a stronger bond with concrete, thus better able to withstand external forces. Rebar is widely used in various building structures. In particular, in large, heavy, lightweight, thin-walled, and high-rise structures, construction steel serves as a fundamental component, serving as a multifaceted component. A typical building component, the steel cage, is composed of multiple groups of steel bars. To ensure the regularity of the finished cage, the steel bars typically require positioning and installation.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-5 The present invention provides a technical solution: a steel bar positioning structure for construction, including a steel cage assembly positioning mechanism, the steel cage assembly positioning mechanism includes a positioning main disk, a driver and a movable main disk, the positioning main disk includes an inner disk 1 and several groups of collars 2 embedded in the inner disk 1, the bottom of the inner disk 1 is connected to the driver by bolts, several groups of collars 2 are concentrically distributed on the inner disk 1 and the periphery is processed to have steel bar positioning grooves 3, three groups of lockers are installed between two adjacent groups of collars 2, the locker includes a rotary locking rod 4 and a positioning rod 5 used in conjunction with the rotary locking rod 4, the outer end of the rotary locking rod 4 is clamped on the positioning rod 5, the steel bar positioning groove 3 is equipped with a magnetic attraction mechanism 6, and the steel bar body 7 is inserted between the two groups of steel bar positioning grooves 3 symmetrically above and below. It includes a hydraulic cylinder 8 and a push rod 9. The hydraulic cylinder 8 is fixed on the inner disk 1 and the power output end is connected to the push rod 9. The power output end of the push rod 9 is connected to the movable main disk. The movable main disk has the same structure as the positioning main disk. When the steel cage needs to be assembled, the staff can adjust the specifications of the positioning main disk and the movable main disk according to the size of the steel cage to be built. After the adjustment is completed, the steel bars are evenly arranged in a ring shape between the positioning main disk and the movable main disk, and the magnetic suction mechanism on the positioning main disk and the movable main disk is opened to fix the steel bars. Then the staff performs welding reinforcement on the overall outline to achieve the purpose of building the steel cage. This construction method can greatly improve the construction speed and regularity of the steel cage.

[0024] Further improvement, such as Figure 2 As shown: the inner side of the ring 2 is processed and formed with several groups of docking protrusions 10, and the number of the docking protrusions 10 of the ring 2 is the same as the number of the steel bar positioning grooves 3 on the inner side of the ring 2. This design makes it easy to dock two adjacent groups of rings 2.

[0025] Further improvement, such as Figure 2 As shown: a mounting plate 11 is fixed to the bottom of the inner plate 1, an embedded groove 12 is formed in the mounting plate 11, and the hydraulic cylinder 8 is embedded in the embedded groove 12. This design method facilitates the hidden installation of the hydraulic cylinder 8 and reduces space occupancy.

[0026] Further improvement, such as Figure 4As shown, the outer end of the rotary lock rod 4 is movably arranged on the collar 2 through a latch and the inner end is processed and formed with a notch 13, and a limiting hole 14 is longitudinally provided at the edge of the notch 13.

[0027] Further improvement, such as Figure 5 As shown: a U-shaped groove 15 is formed on one side of the positioning rod 5, and an elastic gasket 16 is provided on the upper edge of the U-shaped groove 15. The elastic gasket 16 is movably arranged in the U-shaped groove 15 and two groups of sliders 17 are symmetrically fixed on the edge. Two groups of slide grooves 18 are also symmetrically opened in the U-shaped groove 15, and the two groups of sliders 17 are slidably set in the two groups of slide grooves 18. This design makes it easy for the notch 13 of the rotary locking rod 4 to be embedded in the U-shaped groove 15 of the positioning rod 5, and the positioning pin 21 is inserted into the limiting hole 14 to achieve the purpose of fixation.

[0028] Further improvement, such as Figure 5 As shown: the elastic gasket 16 includes a metal spring 19 and a handle 20 fixed to the outside of the metal spring 19. The metal spring 19 has a stacked structure and a positioning pin 21 is formed on the lower edge. The positioning pin 21 is snapped into the limiting hole 14. The staff holds the handle 20 and pulls it upward. During the pulling process, the metal spring 19 contracts, which can make the positioning pin 21 disengage from the limiting hole 14, thereby achieving the purpose of separating the rotary locking rod 4 and the positioning rod 5.

[0029] Further improvement, such as Figure 3 As shown: the magnetic attraction mechanism 6 includes an arc-shaped pad 22 and two groups of electromagnetic sheets 23 fixed on the arc-shaped pad 22. The two ends of the electromagnetic sheet 23 are connected to an external power supply through a circuit. The steel bar body 7 is built into the arc-shaped pad 22 and adsorbed on the electromagnetic sheet 23. When the electromagnetic sheet 23 is energized, magnetism is generated to perform adsorption-type positioning processing on the steel bar body 7. Then the staff can perform component nesting and welding processing between the steel bars. The operation is simple and easy to use.

[0030] Specifically, the structure of the positioning main plate and the movable main plate are the same and the specifications are consistent. This design method can ensure the regularity of the steel cage and effectively reduce the situation where the specifications of the two ends of the steel cage are inconsistent.

[0032] During use: When it is necessary to position and construct the steel cage of the present invention, the staff drives the pushing rod 9 to move horizontally through the hydraulic cylinder 8 according to the length of the steel cage to be constructed, and pushes the movable main disk, so that the distance between the positioning main disk and the movable main disk is adjusted to the required length. Then, according to the specifications of the steel cage to be constructed, the corresponding number of rings 2 can be installed or removed so that the diameters of the positioning main disk and the movable main disk can be adjusted. After the adjustment is completed, the notch 13 of the rotary locking rod 4 is embedded in the U-shaped groove 15 of the positioning rod 5, and the positioning pin 21 is inserted into the limiting hole 14 to achieve the purpose of fixation. Finally, the power is turned on, and the steel bars are set one by one between the two adjacent groups of steel bar positioning grooves 3 above and below, and are adsorbed and fixed by the magnetic attraction mechanism 6. Finally, the staff can perform component nesting and welding between the steel bars. The operation is simple and easy to use. After the steel cage is constructed, the internal steel cage assembly positioning mechanism can be detached. The steel cage assembly positioning mechanism designed by the present invention can realize the rapid distribution, positioning and fixation of the steel bars, which greatly improves the assembly efficiency of the steel cage.
