Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a cylindrical steel cage positioning clamp. Background Technology

[0002] In the field of building construction, cylindrical steel reinforcement cages serve as a crucial framework in concrete structures, and their fabrication quality directly impacts the stability and safety of the entire building structure. The main steel bars, as a key component of the reinforcement cage, require precise and secure connection to ensure its quality.

[0003] Currently, there are many problems that urgently need to be solved in the clamping process of the main reinforcing bars of cylindrical steel cages. Traditional clamping methods often lack precise positioning devices, which makes it easy for the main reinforcing bars to derail during placement. This not only affects the clamping efficiency but may also cause damage or positional deviation of the main reinforcing bars, thereby affecting the overall quality of the steel cage.

[0004] Meanwhile, existing clamps lack structural stability when fixing main reinforcing bars, making it difficult to guarantee the accuracy of the main reinforcing bar position during subsequent construction. Moreover, the insertion and fixing of the main reinforcing bars during the clamping process is cumbersome, lacking convenient and efficient operation methods, which increases the workload and difficulty of construction workers.

[0005] In addition, traditional clamps are difficult to effectively limit and fix the main reinforcing bars after clamping. During transportation or hoisting, the main reinforcing bars are prone to displacement, which affects the overall structure and performance of the reinforcing cage.

[0006] Therefore, a cylindrical steel cage positioning clamp is proposed to solve the problems of low efficiency and quality in the current steel bar main reinforcement clamping. Utility Model Content

[0007] The purpose of this invention is to provide a cylindrical steel cage positioning clamp for existing devices, in order to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cylindrical rebar cage positioning clamp, including a bracket, a fixing block fixed on the bracket, a clamp installed on the fixing block, the clamp including an upper clamp and a lower clamp, the lower clamp being fixed to the fixing block, the lower clamp being semi-circular, the lower clamp having several slots formed according to the spacing of the main rebar bars, one of the slots forming an angle, and a main rebar bar being fixed at the angle of the slot; the upper clamp is slidably connected to one side of the lower clamp, and several sliding guide rails are fixed on the outer diameter of the upper clamp, the sliding guide rails sliding on the outer diameter of the lower clamp;

[0009] A limiting plate is slidably connected to the upper clamp between the two sliding guide rails. One of the upper clamps has a sliding groove. A limiting rod is fixed to the side of the limiting plate near the upper clamp with the sliding groove. The limiting rod is slidably connected to the sliding groove. The side of the limiting plate away from the sliding groove is engaged with the side wall of the other lower clamp. An installation groove is provided in the limiting plate. The installation groove passes through the outer diameter of the limiting plate and is provided with a telescopic plate. A spring is fixed between the telescopic plate and the installation groove. Two limiting blocks are fixed to the side of the telescopic plate away from the installation groove. One limiting block is located inside the upper clamp, and the other limiting block is exposed outside the upper clamp.

[0010] This utility model further describes that the sliding guide rail has a snap-fit ​​groove at one end along the sliding path and a sliding hole at the other end. A sliding rod is slidably connected in the sliding hole, and a driving rod is fixed on the sliding rod. The driving rod passes through the outer diameter of the sliding guide rail and slides on its outer diameter. A second spring is sleeved on the outer diameter of the sliding rod. One end of the second spring contacts the driving rod, and the other end is fixed to the sliding guide rail.

[0011] This utility model further illustrates that the upper and lower clamps are semi-circular.

[0012] The present invention further explains that a plurality of slots are provided on the outer diameter of the upper clamp; the slots form an angle.

[0013] This utility model further illustrates that the sliding rod is adapted to the snap-fit ​​groove.

[0014] This utility model further illustrates that one included angle of the card slot is an acute angle.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: In this utility model, the lower clamp is provided with several slots with acute angles according to the spacing of the main reinforcing bars, and the main reinforcing bars are fixed at the angle of the slots. This design can play a role in precise positioning when the main reinforcing bars are placed, effectively avoiding the problem of the main reinforcing bars derailing, improving the accuracy and efficiency of the main reinforcing bar clamping, and reducing the damage and positional deviation of the main reinforcing bars caused by derailment.

[0016] A limiting plate is slidably connected to the upper clamp between the two sliding guide rails. The limiting plate is slidably connected to the sliding groove inside the upper clamp via a limiting rod, and the side of the limiting plate away from the sliding groove is engaged with the side wall of the lower clamp. This limiting structure can effectively limit and fix the adjacent upper clamps after the upper and lower clamps are engaged, ensuring that the main reinforcing bars of the steel cage will not shift during subsequent transportation and hoisting, thus improving the overall structural stability of the steel cage.

[0017] The limiting plate is equipped with a telescopic plate and a spring. By pressing the telescopic plate, the limiting block can be retracted into the upper clamp, which facilitates the insertion of the main reinforcing bar. After releasing the telescopic plate, the spring pushes the telescopic plate and the limiting block to reset, so that the limiting block can limit the adjacent upper clamp. The operation is simple and the limiting is reliable.

[0018] The sliding guide rail is equipped with a locking groove, sliding hole, sliding rod, drive rod, and spring. By rotating the drive rod, the sliding rod can slide out of the locking groove and into the sliding guide rail. This design allows for easy unlocking of the sliding guide rail when the position of the upper clamp needs to be adjusted or other operations are performed, facilitating operation and adjustment by the staff and improving the flexibility and practicality of the equipment.

Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-6 The present invention provides a technical solution: a cylindrical steel cage positioning clamp, including a bracket 1.

[0029] like Figure 1 and Figure 2 As shown, in some embodiments, a fixing block 2 is fixed on the bracket 1, and a clamp 3 is installed on the fixing block 2. The clamp 3 includes an upper clamp 301 and a lower clamp 302. The lower clamp 302 is fixed to the fixing block 2. The lower clamp 302 is semi-circular. The lower clamp 302 has several slots 303 according to the spacing of the main reinforcing bars. An angle is formed at the slots 303. The main reinforcing bars 304 are fixed at the angle of the slots 303 to prevent the main reinforcing bars 304 from derailing when placed.

[0030] The lower clamp 302 is slidably connected to the upper clamp 301 on one side. A plurality of sliding guide rails 305 are fixed on the outer diameter of the upper clamp 301, and the sliding guide rails 305 slide on the outer diameter of the lower clamp 302; wherein:

[0031] like Figure 5 and Figure 6 As shown, in some embodiments, a limiting plate 307 is slidably connected to the upper clamp 301 between the two sliding guide rails 305. One of the upper clamps 301 has a sliding groove 3011. A limiting rod 3071 is fixed to the side of the limiting plate 307 near the upper clamp 301 with the sliding groove 3011. The limiting rod 3071 is slidably connected to the sliding groove 3011. The side of the limiting plate 307 away from the sliding groove 3011 is engaged with the side wall of the other lower clamp 302.

[0032] The limiting plate 307 has an installation groove 3072, which penetrates the outer diameter of the limiting plate 307 and is provided with a telescopic plate 3073. A spring 3074 is fixed between the telescopic plate 3073 and the installation groove 3072. Two limiting blocks 3075 are fixed on the side of the telescopic plate 3073 away from the installation groove 3072. One limiting block 3075 is located inside the upper clamp 301, and the other limiting block 3075 is exposed outside the upper clamp 301.

[0033] like Figure 3 and Figure 4 As shown, in some embodiments, the sliding guide rail 305 has a snap-fit ​​groove 3051 at one end along the sliding path and a sliding hole 3052 at the other end. A sliding rod 3053 is slidably connected in the sliding hole 3052, and a drive rod 3054 is fixed on the sliding rod 3053. The drive rod 3054 passes through the outer diameter of the sliding guide rail 305 and slides on its outer diameter. A second spring 3055 is sleeved on the outer diameter of the sliding rod 3053. One end of the second spring 3055 contacts the drive rod 3054, and the other end is fixed to the sliding guide rail 305.

[0034] It should be noted that the sliding rod 3053 is adapted to the snap-fit ​​groove 3051.

[0035] It should be further explained that: the upper clamp 301 is semi-circular, and a plurality of slots 306 are formed on the outer diameter of the upper clamp 301; the slots 306 form an angle;

[0036] It should be noted that when the lower clamp 302 coincides with the upper clamp 301, the angle between the second clamp 306 and the angle between the first clamp 303 corresponds to the position of the second clamp.

[0037] It should be noted that the included angle at slot 303 is an acute angle.

[0038] Working principle:

[0039] The steps for connecting the main 304 steel bars of the cylindrical steel cage are as follows:

[0040] S1: Slide the upper clamp 301 until it coincides with the vertical plane of the lower clamp 301. At this time, the second clamp 306 and the first clamp 303 partially overlap.

[0041] S2: By pressing the telescopic plate 3073, the telescopic plate 3073 and the limiting block 3075 enter the interior of the mounting groove 3072. By sliding the limiting rod 3071, the limiting rod 3071 drives the limiting plate 307 to retract into the upper clamp 301.

[0042] S3: Insert the main reinforcing bar 304 into the overlapping portion of the slot 2 306 and the slot 1 303 through the gap between the two adjacent upper clamps 301.

[0043] S4: When there is a main steel bar 304 in the overlapping part of the second slot 306 and the first slot 303, rotate the upper clamp 301. During the rotation, the main steel bar 304 in the overlapping part of the second slot 306 and the first slot 303 is pushed out through the gap between the two adjacent upper clamps 301 and slides down to the bottom of the lower clamp 302 under the action of gravity.

[0044] S5: When the upper clamp 301 and the lower clamp 302 form a complete circle, the worker inserts the main steel bars 304 in the lower clamp 302 one by one into the slot 303.

[0045] S6: By sliding the limiting rod 3071, the limiting plate 307 is slid out of the upper clamp 301. When the limiting block 3075 enters the interior of the adjacent upper clamp 301, the two adjacent upper clamps are fixed by the limiting plate 307.

[0046] S7: Rotate the drive rod 3054 to make the sliding rod 3053 slide out of the snap-fit ​​groove 3051 and slide into the sliding guide rail 305.

[0047] S8: The worker places the main steel bar 304 into the slot 2 306. When each slot 2 306 contains the main steel bar 304, the main steel bar 304 of the cylindrical steel cage is successfully connected.
