Description

Technical Field

[0001] The utility model relates to the technical field of small prefabricated parts manufacturing, in particular to a steel bar positioning tool for a bridge railing column. Background Art

[0002] The bridge railing column is a concrete component of bridge engineering, which is generally produced by prefabrication. The prefabrication production process requires the use of vibration equipment for vibration. The traditional production of prefabricated parts will add a steel skeleton, and the fixation of the steel skeleton has become a difficult problem in prefabrication quality control. The traditional method of tying steel bars and setting gaskets under the steel skeleton to support the steel skeleton is difficult to use in the prefabrication mold of bridge railing columns. It mainly has the following difficulties:

[0003] The bridge railing columns are small in structure and difficult to raise by placing stones under the steel frame;

[0004] Since the concrete needs to be vibrated, it is easy to vibrate the steel frame off the stone during the vibration process, which will cause the steel bars to be exposed and make the cast column protective layer unable to meet the design requirements.

[0005] In order to address the above problems, a bridge railing column steel bar positioning tool is urgently needed. Utility Model Content

[0006] The utility model aims to provide a bridge railing column reinforcement positioning tool to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above purpose, a bridge railing column steel bar positioning tool is provided, comprising an angle steel and a crossbeam, wherein both ends of the crossbeam are fixedly connected to the angle steel, and the angle steel and the crossbeam are combined to form a U-shaped fixture;

[0008] A rotary positioning assembly, which is in an inverted "T" shape and includes a vertical portion and a horizontal portion. The vertical portion of the rotary positioning assembly passes through the crossbeam and can rotate, and the horizontal portion supports the steel bar as the vertical portion rotates;

[0009] The crossbeam is also provided with a limit assembly for limiting the left and right movement of the steel bars;

[0010] The top end of the vertical part of the rotary positioning assembly is fixedly connected to a crossbar, and a stop bar is provided on the top of the crossbar. When the crossbar can come into contact with the stop bar as the vertical part rotates, the stop bar can limit the crossbar from continuing to rotate in the original direction.

[0011] Furthermore, the rotary positioning assembly also includes a threaded sleeve that vertically penetrates the cross beam, the vertical portion is threadedly installed in the threaded sleeve, and two limit rings are fixedly installed on the vertical portion, one of which is located above the cross beam and the other is located below the cross beam.

[0012] Furthermore, the limit assembly includes a limit rod, a limit groove, a locking nut and a positioning ring. The limit assembly includes at least two groups, which are respectively located on both sides of the rotary positioning assembly. The limit groove is opened on the beam, and the limit rod passes through the limit groove from top to bottom. The locking nut is threadedly connected to the limit rod, and the positioning ring is fixedly sleeved on the limit rod, wherein the locking nut is located above the beam and the positioning ring is located below the beam.

[0013] Furthermore, the limiting rod can slide left and right in the limiting groove, and the minimum distance between the limiting rods on both sides is greater than the length of the horizontal part of the rotary positioning assembly, and the maximum distance does not exceed the distance between the angle steels on both sides.

[0014] Furthermore, the cross bar and the rotary positioning assembly are combined to form a handle for disassembly and taking.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The horizontal part can be raised by rotating the rotary positioning assembly with the crossbar, and the steel bars inside the mold can be lifted, so that the steel bars are located in the center of the mold, ensuring the spacing of the steel bar skeleton, avoiding the phenomenon of exposed steel bars after pouring, and making the poured protective layer meet the design requirements;

[0017] The combination of the crossbar and the rotating and rotatable positioning assembly forms the handle of the device, which has a simple structure and is easy to dismantle. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Those skilled in the art will appreciate that, unless otherwise stated, the singular forms "a", "an" and "the" used herein may also include plural forms. It should be further understood that the term "comprising" used in the specification of the present utility model refers to the presence of the features, integers, steps, operations, elements and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0025] See also Figure 1-3 As shown, a bridge railing column reinforcement positioning tool is provided, comprising an angle steel 1 and a cross beam 2, wherein both ends of the cross beam 2 are fixedly connected to the angle steel 1, and the angle steel 1 and the cross beam 2 are combined to form a U-shaped fixture; it is worth noting that Figure 2 It can be seen that the angle steel 1 is mounted on the mold of the bridge railing column, which supports the entire device, and the "L"-shaped angle steel 1 can prevent the device from lateral displacement on the mold, thereby ensuring its stability;

[0026] The rotary positioning assembly 3 is in an inverted "T" shape, including a vertical portion and a horizontal portion. The vertical portion of the rotary positioning assembly 3 penetrates the crossbeam 2 and can rotate, and the horizontal portion supports the steel bar as the vertical portion rotates. Figure 2 It can be seen that the two upper steel bars are hung on the horizontal part of the rotary positioning assembly 3, so that the position of the steel bars is at the inner center of the column, and the steel bars will not be exposed, thereby improving the pouring strength of the column;

[0027] The crossbeam 2 is also provided with a limit assembly 4 for limiting the left and right movement of the steel bar. The limit assembly 4 can ensure that the steel bar will not deviate when the column is vibrated during pouring, and avoid falling off from the horizontal part of the rotary positioning assembly 3;

[0028] The top end of the vertical part of the rotary positioning component 3 is fixedly connected to the cross bar 5, and a stop bar 6 is provided on the top of the cross beam 2. When the cross bar 5 can come into contact with the stop bar 6 as the vertical part rotates, the stop bar 6 can limit the cross bar 5 from continuing to rotate in the original direction. Since the length of the horizontal part is greater than the width of the steel bar, when placing the device, it is necessary to adjust the horizontal part to a state of crossing the cross beam 2 through the rotary positioning component 3, and then rotate the cross bar 5 so that the two ends of the horizontal part contact the steel bar. During the rotation, the horizontal part will rise and drive the steel bar to the center position of the mold at the same time. The stop bar 6 is to prevent the horizontal part from crossing the cross beam 2 again due to excessive rotation angle.

[0029] Please combine Figure 1 and Figure 2 As shown:

[0030] The rotary positioning assembly 3 further includes a threaded sleeve 301 vertically penetrating the cross beam 2, the vertical portion is threadedly installed in the threaded sleeve 301, and two limit rings 302 are fixedly installed on the vertical portion, one of which is located above the cross beam 2 and the other is located below the cross beam 2;

[0031] The limiting assembly 4 includes a limiting rod 401, a limiting groove 402, a locking nut 403 and a positioning ring 404. The limiting assembly 4 includes at least two groups, which are respectively located on both sides of the rotary positioning assembly 3. The limiting groove 402 is opened on the beam 2, and the limiting rod 401 passes through the limiting groove 402 from top to bottom. The locking nut 403 is threadedly connected to the limiting rod 401, and the positioning ring 404 is fixedly sleeved on the limiting rod 401, wherein the locking nut 403 is located above the beam 2, and the positioning ring 404 is located below the beam 2.

[0032] like Figure 2 As shown, the principle of the limit assembly 4 is as follows:

[0033] After the steel bar is lifted by the rotary positioning assembly 3, the locking nut 403 is loosened, and then the limiting rod 401 is moved to both sides of the steel bar to limit its left and right directions. After the position of the locking nut 403 is adjusted, the locking nut 403 is tightened to fix the position of the limiting rod 401. Figure 2 It can also be seen that the locking nut 403 is also provided with a gasket to prevent it from loosening when the concrete is vibrated.

[0034] The limiting rod 401 can slide left and right in the limiting groove 402, and the minimum distance between the limiting rods 401 on both sides is greater than the length of the horizontal part of the rotary positioning assembly 3, and the maximum distance does not exceed the distance between the angle steels 1 on both sides;

[0035] The combination of the cross bar 5 and the rotary positioning assembly 3 constitutes a handle for disassembly and taking. Since the device needs to be dismantled after the initial setting of the concrete, the presence of the handle provides a force point for easy disassembly. In addition, the cross bar 5 is a component in the device that is not easy to contact with concrete. It is also convenient for construction workers to take it as a handle to avoid direct contact between their hands and concrete.

[0036] Working principle:

[0037] Before pouring concrete, the angle steel 1 is buckled on the surface of the bridge railing column mold. At this time, the horizontal part of the rotary positioning component 3 should be in a state of crossing with the crossbeam 2 (otherwise it cannot be placed under the steel bar). Then the rotary positioning component 3 is rotated by the crossbar 5, specifically, the crossbar 5 is rotated 90 degrees, so that the horizontal part of the rotary positioning component 3 changes from crossing with the crossbeam 2 to overlapping. In this process, both ends of the horizontal part contact with the steel bar, and the horizontal part moves upward with the rotation, and the steel bar is lifted at the same time, so that the steel bar is in the center of the mold;

[0038] Then, the specific position of the limit rod 401 is adjusted to fix the left and right directions of the steel bar, so as to prevent the steel bar from falling off from the horizontal part during the vibration of the concrete.

[0039] After the concrete pouring is completed and the initial setting is completed, the cross bar 5 is rotated in the opposite direction so that the horizontal part of the rotary positioning assembly 3 is again in a state of crossing with the cross beam 2, and then the device can be removed by lifting the cross bar 5.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
