Description

Technical Field

[0001] The utility model relates to the technical field of steel bars, in particular to a steel bar limiting pier for construction. Background Art

[0002] Currently, traditional steel bar limit piers used in construction on the market have significant limitations in practical applications. Especially when the bottom steel bars need to be removed, users often need to lift or remove the upper steel bars one by one. This process not only consumes a lot of physical strength, but also increases work intensity, reduces construction efficiency, and brings many inconveniences to users.

[0003] Chinese patent CN212402009U proposes a steel bar limit pier for construction. Its structure is relatively complex, encompassing multiple precision components, including but not limited to a housing, sliding rods, threaded rods, rotating shafts, and a sophisticated mechanical transmission mechanism. This complex design can lead to loosening or damage of components during long-term use and frequent assembly and disassembly, leading to a series of maintenance and repair issues.

[0004] Furthermore, the piers are assembled using a continuous splicing process. While this facilitates height adjustment and access to rebar, in practice, when the rebar is subjected to significant downward pressure, the splicing locations can bend and deform, affecting the stability and service life of the piers. This potential risk of failure not only increases repair costs but also poses a threat to construction safety. Utility Model Content

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A steel bar limiting pier for construction includes a base frame, which includes a front plate, a rear plate and multiple intermediate plates. Several intermediate plates are provided between the front plate and the rear plate. Several vertical through holes are provided on the intermediate plates. Limiting rods are slidably fitted in the vertical through holes. A support block is provided at the bottom of the base frame, and a locking mechanism is installed on the support block. The locking mechanism can limit the movement of the limiting rod along the vertical through holes.

[0008] Furthermore, the locking mechanism includes an insert rod and a locking bolt, a sleeve is provided at the lower end of the limit rod, a guide hole is provided on the support block, a locking bolt is threadedly connected to the support block, and an insert rod is slidably fitted in the guide hole.

[0009] Furthermore, the insertion rod can be inserted into the sleeve and the guide hole to limit the vertical movement of the limit rod, and the locking bolt is used to limit the movement of the insertion rod along the guide hole.

[0010] Furthermore, a supporting plate is provided between adjacent middle plates.

[0011] Furthermore, the insertion rod is provided with a plurality of through holes, and fastening bolts are installed in the through holes. The fastening bolts pass through the through holes and are threadedly connected to the threaded holes at the bottom of the middle plate.

Compared to traditional limiting piers, the present invention is not only simpler to operate, significantly reduces workload, and improves construction efficiency, but also significantly enhances structural stability and load-bearing capacity through an enhanced locking mechanism and reinforced outer tube design, effectively preventing problems such as loosening and damage of components, as well as bending and deformation of the plug-in parts, thereby reducing maintenance costs and the risk of failure.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0020] First embodiment

[0021] like Figure 1-Figure 3 As shown, a steel bar limiting pier for construction includes a base frame 100, which is made of durable alloy steel to ensure stability and durability during long-term use. The base frame includes a front plate 101, a rear plate 102, and a plurality of intermediate plates 103 arranged at a certain interval. A plurality of intermediate plates are provided between the front plate and the rear plate. The intermediate plates are provided with a plurality of vertical through holes 11 processed according to standard specifications (such as M20). The limit rods 2 are slidably fitted in the vertical through holes. The limit rods 2 are also made of high-strength alloy steel and the surface is rust-proofed to improve their corrosion resistance. A support block 3 is provided at the bottom of the base frame, and a locking mechanism is installed on the support block. The locking mechanism can limit the movement of the limit rod along the vertical through hole.

[0022] The structure is simple in design. When the limit rod needs to be moved vertically downward, the locking mechanism can be disassembled so that the limit rod can be moved downward along the vertical through hole, thereby preventing the limit rod from affecting the handling of steel bars.

[0023] In at least one embodiment, the locking mechanism includes a rod 22 and a locking bolt 31. A sleeve 21 is provided at the lower end of the limiting rod. A guide hole is provided in the support block, and a locking bolt is threadedly connected to the support block. The rod slidably fits within the guide hole. The rod surface is hardened to improve its wear resistance and service life. The rod can be inserted into the sleeve and guide hole to limit the vertical movement of the limiting rod, and the locking bolt is used to limit the rod's movement along the guide hole.

[0024] Furthermore, a supporting plate 104 is provided between adjacent middle plates.

[0025] In some embodiments, in order to enhance the connection effect between the insertion rod and the base frame, the insertion rod is provided with a plurality of through holes, in which fastening bolts are installed. The fastening bolts pass through the through holes and are threadedly connected to the threaded holes at the bottom of the middle plate.

[0026] Second embodiment

[0027] The difference from the first embodiment is that an outer tube 23 is slidably fitted on the outside of the limit rod, and the outer tube is fixedly connected to the limit rod by bolts 24 and nuts 25. The outer tube design allows for more steel bars to be loaded, and the bolt connection between the two is more secure and the cost is also low.

[0028] Working method, ensure that the base frame is intact. Check whether the vertical through-hole is unobstructed and free of obstructions. Confirm that the limit rod, sleeve, insert rod, locking bolt and other components are complete and functioning properly. If an outer tube is required, ensure that the bolts, nuts and other connectors are fully prepared. Insert the limit rod into the vertical through-hole of the base frame, and ensure that the limit rod can slide freely but not shake. If an outer tube is required, slide the outer tube onto the outside of the limit rod and tighten it with bolts and nuts. Use the locking mechanism to fix the limit rod in the desired position. Insert the insert rod into the guide holes of the sleeve and support block. Tighten the locking bolt to ensure that the insert rod does not move along the guide hole, thereby limiting the vertical movement of the limit rod. Place the steel bar on the support plate of the base frame, with the steel bar between the two sets of limit rods, to ensure that the steel bar is stable and does not shake. When the steel bar needs to be removed, loosen the locking bolt first. Pull out the insert rod, release the restriction on the limit rod and move the steel bar away.

[0029] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
