Abstract
Description
Technical Field
[0001] The present application relates to the technical field of auxiliary props for decoration construction, and more specifically to an auxiliary tool for reinforcing reinforced concrete beams by embedding reinforcement bars. Background Art
[0002] During the renovation process, users often need to make the door body higher, and in this case, the door opening needs to be expanded. In some early-construction house structures, in order to simplify the construction, the house construction personnel extend the door beam steel bars to a predetermined distance below the bottom bars of the load-bearing beam, and then cast them with concrete. When expanding the door opening, there is a phenomenon that the door opening expansion personnel may destroy the concrete structure above the original door body and cut off the door beam steel bars. At this time, some owners with a high sense of safety and sensitivity will require the door beam steel bars and the door opening to be restored to their original state.
[0003] In the repair of the steel bars of the door beam, there is a simplified repair and reinforcement method that does not damage the concrete structure in a large area, such as Figure 1 As shown, holes are drilled on the concrete walls on both sides, and then anchor glue is injected. Then, the two ends of a steel bar 90 are respectively inserted into the holes on both sides. After the anchor glue is cured, the steel bar 90 provides a certain tensile force. However, if the overall length of the steel bar 90 exceeds the width of the door opening 91 by a large amount, it is difficult for construction workers to insert both ends of the steel bar 90 into the corresponding holes. If the overall length of the steel bar 90 is slightly longer than the width of the door opening 91, although the steel bar 90 can be appropriately bent so that the two ends of the steel bar 90 can be inserted into the corresponding holes, in fact, the depth of the two ends of the steel bar 90 inserted into the corresponding holes is relatively shallow. In standard construction, the depth of the steel bar 90 inserted into the hole should be greater than or equal to ten times the diameter of the steel bar 90, which is far from being achieved by the above reinforcement scheme. Therefore, there is an optimized reinforcement method, such as Figure 2 As shown, by inserting two steel bars 90 into the corresponding holes respectively, and then welding the ends of the two steel bars 90 away from the holes, the depth dimension of each steel bar 90 extending into the corresponding hole is compliant, and it is easy to insert the steel bar 90 into the hole. Compared with the previous reinforcement method, it can obviously connect the concrete structures on both sides of the door opening 91 and provide higher tensile strength. However: In this reinforcement scheme, the construction workers need to ensure that the edges of one side of the two holes are flush when drilling the corresponding holes, so that after the steel bars 90 are placed, it is easy to arrange the two steel bars 90 in parallel and provide more welding areas. How to more accurately and efficiently locate the holes on the concrete structures on both sides of the door opening 91 is a technical problem to be solved.
[0004] Therefore, there is a need to provide a reinforced concrete beam reinforcement auxiliary tool that can accurately and efficiently locate the drilling position. Summary of the invention

[0032] The terms used herein are only used for the purpose of describing various embodiments and are not intended to be limiting. As used herein, singular forms are intended to also include plural forms, unless the context clearly indicates an exception. In addition, it will be understood that the terms "including" and / or "having" when used in this specification specify the presence of the described features, numbers, steps, operations, components, elements or combinations thereof, without excluding the presence or addition of one or more other features, numbers, steps, operations, components, elements or groups thereof.
[0033] Schematic reinforced concrete beam reinforcement auxiliary tool,
[0034] refer to Figures 3 to 6 According to a preferred embodiment of the utility model, a reinforced concrete beam reinforcement auxiliary tool is provided. Figure 3 , Figure 4 and Figure 5 As shown, it includes a bracket 10, a rotating member 20, a mounting seat 30 and a laser pen 40. The rotating member 20 is rotatably mounted on the bracket 10, the mounting seat 30 is arranged on the rotating member 20 and rotates circumferentially with the rotating member 20, and the laser pen 40 is mounted on the mounting seat 30.
[0035] It should be noted that, when in use, the bracket 10 is placed on a horizontal ground, and the rotating member 20 is adjusted to a predetermined height. It should be pointed out that the distance between the central axis of the laser pen 40 and the rotation center of the rotating member 20 is the radius of the predetermined implanted steel bar plus two millimeters, so that the laser pen 40 faces the concrete structure on one side of the door opening. Subsequently, the construction personnel make a cross mark on the designated position irradiated by the laser pen 40. After marking, the construction personnel rotate the rotating member 20 180°, and the laser pen 40 irradiates the concrete structure on the other side of the door opening. Since the distance between the central axis of the laser pen 40 and the rotation center of the rotating member 20 remains unchanged, only the direction of the laser pen 40 is opposite, that is, it forms a central symmetrical arrangement with the previous position, the construction personnel can quickly make a cross mark on the concrete structure on the other side. When the construction personnel drill holes according to the two cross marks, the edges of one side of the two holes drilled are flush, which provides conditions for the subsequent placement of steel bars into the holes and the parallel arrangement of the two steel bars. It is obvious that compared with the prior art, it has the advantage of being able to accurately and efficiently locate the drilling position.
[0036] Further, for implant positioning using various rebar diameters, e.g. Figure 4 As shown, the mounting seat 30 is slidably disposed on the rotating member 20 in the height direction of the rotating member 20 .
[0037] It should be noted that since the radius of the predetermined implanted steel bar plus two millimeters is the distance from the central axis of the laser pen 40 to the rotation center of the rotating part 20, it should be supplemented that the two-millimeters radial margin is to provide space for the rebar embedding glue injected into the hole. This size is not a fixed value and can be increased or decreased according to the amount of rebar embedding glue injected. By making the mounting seat 30 slidable in the height direction of the rotating part 20, the distance from the central axis of the laser pen 40 to the rotation center of the rotating part 20 can be adjusted.
[0038] Specifically, in order to realize that the mounting seat 30 can be lifted and slidably disposed on the rotating member 20, as shown in FIG. Figure 4 and Figure 5As shown, the rotating member 20 includes a rotating seat 201 and two extension seats 202 arranged at intervals. The two extension seats 202 are located on the same side of the rotating seat 201 and are fixedly connected to the rotating seat 201. The fixed connection method includes but is not limited to bolt connection. Each of the extension seats 202 has a plurality of guide grooves 2021. In the embodiment of the present application, each of the extension seats 202 has two vertically arranged guide grooves 2021, and the two guide grooves 2021 are waist-shaped grooves. One end of the mounting seat 30 has an insertion portion 301, and the insertion portion 301 extends into the two extension seats 202 and is slidably arranged in the guide groove 2021 through the shaft body 302. More specifically, the two guide grooves 2021 on the two extension seats 202 are opposite to each other, and the mounting seat 30 includes two shaft bodies 302, the shaft bodies 302 pass through the insertion portion 301, and both ends of each shaft body 302 respectively extend into the guide groove 2021 on the corresponding extension seat 202, and the side wall of the shaft body 302 is in contact with the groove wall of the guide groove 2021; in addition, in order to realize the selective fixation of the mounting seat 30 in the height direction of the rotating member 20, one of the extension seats 202 has a through first threaded hole (not marked in the figure), and the reinforced concrete beam anchor reinforcement auxiliary tool also includes a first fastener 50, the first fastener 50 is a bolt, the first fastener 50 is threadedly connected to the first threaded hole and presses against the insertion portion 301 inserted into the two extension seats 202 or the first fastener 50 is separated from the insertion portion 301.
[0039] It should be noted that when the first fastener 50 is threadedly connected to the first threaded hole and pressed against the insertion portion 301, the height position of the mounting base 30 on the rotating member 20 is fixed. When it is necessary to adjust the distance from the central axis of the laser pen 40 to the rotation center of the rotating member 20, the first fastener 50 can be loosened, and the insertion portion 301 can be moved up and down along the guide groove 2021 until it moves to the specified position and then the first fastener 50 is tightened again.
[0040] Furthermore, in order to facilitate the construction workers to quickly raise the laser pen 40 to a specified height, as shown in FIG. Figure 4 As shown, the mounting seat 30 has a center indicator 303, the rotating member 20 has a scale in the height direction, and the pointer pin of the center indicator 303 is flush with the central axis of the laser pen 40 in the height direction. It should be added that the starting zero point of the scale is calculated from the rotation center of the rotating member 20.
[0041] More specifically, if Figure 4 and Figure 5As shown, the extension seat 202 having the first threaded hole has a through slot 2022 , the scale is located on the side of the through slot 2022 , the center indicating portion 303 is fixedly connected to the insertion portion 301 , and the center indicating portion 303 is slidably disposed in the through slot 2022 .
[0042] Furthermore, in order to facilitate the clamping of the laser pen 40, as Figure 4 As shown, the mounting seat 30 has a mounting portion 304 at one end away from the insertion portion 301, and the mounting portion 304 has a partition groove 3041 at one end away from the insertion portion 301. The side wall of the partition groove 3041 has a through second threaded hole, and the center of the mounting portion 304 also has a square groove 3042, and the square groove 3042 is connected to the partition groove 3041.
[0043] It should be noted that when the laser pen 40 is installed on the mounting portion 304, the side wall of the laser pen 40 abuts against the groove wall of the square groove 3042, and the groove wall of the square groove 3042 clamps the laser pen 40 by screwing the external bolts into the second threaded holes on the two side walls of the partition groove 3041 in sequence.
[0044] Furthermore, in order to realize the rotatable installation of the mounting seat 30 on the rotating member 20, as shown in FIG. Figure 4 As shown, the rotating seat 201 has a circular hole 2011, and the circular hole 2011 passes through the rotating member 20. The reinforced concrete beam anchor reinforcement auxiliary tool also includes a lifting seat 60, and the lifting seat 60 is slidably set on the bracket 10 in the height direction of the bracket 10. One end of the lifting seat 60 has an axis body portion 601, and the axis body portion 601 passes through the circular hole 2011 and allows the rotating seat 201 to be rotatably installed on the axis body portion 601.
[0045] Furthermore, in order to realize that the rotating seat 201 can only rotate 180° along the shaft body 601, as shown in FIG. Figure 4 and Figure 6 As shown, the rotating seat 201 also has a circumferentially extending hole 2012, and the circumferentially extending hole 2012 is located at one end of the circular hole 2011. The end of the shaft body 601 close to the circumferentially extending hole 2012 has an arc-shaped protrusion 602, and the arc-shaped protrusion 602 slides along the hole wall of the circumferentially extending hole 2012. The circumferentially extending hole 2012 has a first abutment surface 20121 and a second abutment surface 20122. When the rotating seat 201 rotates relative to the shaft body 601, the arc-shaped protrusion 602 abuts against the first abutment surface 20121 or the second abutment surface 20122.
[0046] Furthermore, in order to realize that the rotating seat 201 can fix its circumferential position after rotating a predetermined angle, as Figure 4 As shown, the shaft body portion 601 is provided with a shoulder portion 603 and a threaded portion 604 at one end of the rotating seat 201, and the rotating seat 201 is located between the shoulder portion 603 and the threaded portion 604, and the threaded portion 604 is threadedly connected to an external nut. When the rotating seat 201 is rotated to a predetermined angle, the two end surfaces of the rotating seat 201 are respectively abutted against the shoulder portion 603 and the external nut by tightening the external nut.
[0047] Furthermore, if Figure 3 and Figure 5 As shown, the bracket 10 includes a supporting plane 1011 and three supporting legs 103 arranged in a circular array. Since the concrete structure on both sides of the door opening after knocking the wall is not a flat surface but bumpy, the supporting plane 1011 is set and when in use, the supporting plane 1011 is made parallel to the wall on one side perpendicular to the door opening, so that the irradiation of the laser pen 40 is not prone to skew; and the three supporting legs 103 are set to prevent the bracket 10 from tilting and shaking.
[0048] In addition, if Figure 3 and Figure 5 As shown, the rotating member 20 is slidably arranged on the bracket 10 in the height direction of the bracket 10, and the abutting plane 1011 can be raised and lowered relative to the support leg 103. Specifically, the bracket 10 includes a base 101 and a lower plug shaft 102, one end of the base 101 is sleeved on the lower plug shaft 102, and the lower plug shaft 102 is fixedly connected to the support leg 103, and its fixed connection method includes but is not limited to welding. The abutting plane 1011 is provided on the base 101, and the rotating member 20 is raised and lowered on the base 101. More specifically, the side wall of the base 101 has a slide groove (not marked in the figure), and the external bolt is threadedly connected to the rotating member 20 and passes through the rotating member 20 and tightens or loosens the base 101. When the external bolts are tightened, the height position of the rotating member 20 on the base 101 is fixed. Conversely, the height of the rotating member 20 can be adjusted after loosening the external bolts. In addition, the lower plug shaft 102 has a plurality of insertion holes (not marked in the figure) arranged at intervals in the height direction, and the base 101 has a pin (not marked in the figure) on one end close to the lower plug shaft 102. The pin is inserted into one of the insertion holes to fix the position of the base 101 on the lower plug shaft 102. Conversely, the base 101 can be raised or lowered relative to the lower plug shaft 102 by pulling out the pin.
[0049] In summary, the reinforced concrete beam anchor bolt reinforcement auxiliary tool based on the embodiment of the present application is explained, which provides the reinforced concrete beam anchor bolt reinforcement auxiliary tool with advantages such as the ability to accurately and efficiently locate the drilling position.
