Description

Technology Field

[0001] The present invention relates to an attachment assist device capable of precisely positioning a crack measurement gauge for precision safety diagnosis, and more specifically, to an attachment assist device comprising a support formed vertically on the bottom surface of an upper frame on which a magnifying glass is installed, and a lower frame through which the support passes, wherein a reference plate is magnetically attached to the support from the lower frame, and the reference crosshair of the reference plate is checked through the magnifying glass to confirm the gauge display of a pre-installed measurement plate, thereby accurately aligning the reference crosshair and the reference point of the gauge display, and then the upper frame is pressed to lower the support so that the reference plate overlaps with the numerical plate and is attached to the crack area. Background Technology

[0002] Generally, architectural or civil engineering structures have a life cycle consisting of the design stage, the construction stage, and the service stage, followed by natural collapse due to the passage of their service life, artificial demolition, or premature collapse due to poor construction or damage. While natural causes resulting from the passage of service life may account for a portion of the causes of such structures' collapse, the vast majority are deeply related to the deformation of the structure caused by external forces acting on it during the construction or service stages.

[0003] Among the structural deformations described above, cracks are generally difficult to detect early due to their minute width and very slow propagation speed; consequently, constructors or users may easily overlook them, assuming they do not significantly affect structural safety. However, since certain cracks can cause structural defects and ultimately lead to structural collapse, cracking is a critical factor in diagnosing structural safety, and measuring instruments for detecting such cracks are also essential devices for assessing structural stability.

[0004] As described above, a crack measuring gauge with a separable structure provided in the form of a plastic ruler is widely used as a conventional technology for measuring crack phenomena occurring in architectural or civil engineering structures.

[0005] As an example of such a crack measuring gauge, a crack measuring gauge is disclosed in Korean registered patent No. 10-2083255, and as shown in FIG. 1, it comprises a rectangular reference plate (100) in the shape of a plastic ruler and a rectangular numerical plate (200) in the shape of a plastic ruler having the same shape for use in matching with the reference plate (100).

[0006] At this time, the reference plate (100) is provided with a reference crosshair, and the numeric plate (200) is provided with a gauge display part (211) based on numerical values ​​and scales.

[0007] The reference plate (100) and the numerical plate (200) are provided with a mutually separable structure. First, the numerical plate (200) is attached to one side of the crack area using an adhesive such as epoxy or a piece. Then, the reference plate (100) is placed overlappingly on the upper surface of the numerical plate (200), and the reference crosshairs are aligned with the gauge display section. After fixing the plate using an adhesive such as epoxy or a piece, the numerical value or scale corresponding to the degree of positional movement or change formed when a crack occurs is checked to measure the condition of the concrete crack.

[0008] However, although this crack measuring gauge has the advantage of accurately determining the progression of cracks in concrete structures with a relatively simple configuration consisting of a pair of plates, the reference crosshairs and the reference point of the gauge display must be accurately aligned during installation. Since the reference plate is attached by hand after the numerical plate is attached, it is difficult to attach it in the correct position, and if it is not attached in the correct position, there is a problem that an error occurs from the setting of the reference point.

[0010] The present invention aims to solve the aforementioned problems by providing an attachment assist device capable of precisely positioning a crack measurement gauge for precision safety diagnosis, comprising a support formed vertically on the bottom surface of an upper frame on which a magnifying glass is installed and a lower frame through which the support passes. In this device, a reference plate is magnetically attached to the support from the lower frame, and the reference crosshairs of the reference plate are checked through the magnifying glass to confirm the gauge display of a pre-installed measurement plate, thereby accurately aligning the reference crosshairs with the reference point of the gauge display. Subsequently, the upper frame is pressed to lower the support, causing the reference plate to overlap with the numerical plate and attach to the crack area. means of solving the problem

[0011] The features of the present invention for achieving the above objectives are,

[0012] The invention is characterized by comprising: an upper frame formed in a rectangular shape and equipped with a magnifying glass; a plurality of support members formed vertically from the bottom surface of the upper frame and equipped with an attachment member on the bottom surface; and a lower frame formed in a rectangular shape, formed so that the support members penetrate, and provided with a seating groove so that a reference plate of a crack measuring gauge is attached to the attachment member of the support member, thereby bringing the reference plate into close contact with the upper surface of the numerical plate of the crack measuring gauge.

[0013] Here, the support member comprises a support member formed with a lower portion having a reduced diameter and fixed to the center of each bottom edge of the upper frame; a coil spring coupled to the lower portion of the support member to provide elasticity to the support member; and a ring plate, wherein the ring plate has a diameter larger than the lower portion of the support member to prevent the support member from detaching from the lower frame, and an attachment member for attaching the reference plate is provided on the bottom surface of the ring plate.

[0014] In addition, the attachment member is a rubber magnet with a relatively weak magnetic force so that the reference plate can be easily detached when attached to the cracked area.

[0015] In addition, the reference plate is provided with a metal plate so as to be attached and fixed to the attachment member by magnetic force at a position corresponding to the attachment member on the upper surface.

[0016] In addition, the lower frame has a through hole formed at a corresponding position so that the lower part of the support penetrates, and the seating groove is formed at the center of each bottom edge of the lower frame.

[0017] In addition, the above-mentioned mounting groove is formed with a width greater than the width of the reference plate so that it does not interfere when the reference plate is lowered by the support and attached to the cracked area. Effects of the invention

[0018] According to the attachment assist device for precise safety diagnosis crack measurement gauge of the present invention configured as described above, the device is composed of a support formed vertically on the bottom surface of an upper frame where a magnifying glass is installed and a lower frame through which the support passes. When a reference plate is magnetically attached to the support from the lower frame, the reference crosshair of the reference plate is checked through the magnifying glass to confirm the gauge display of a pre-installed measurement plate, thereby accurately aligning the reference crosshair with the reference point of the gauge display. Subsequently, the upper frame is pressed to lower the support, causing the reference plate to overlap with the numerical plate and be attached to the crack area in the correct position, thereby preventing the occurrence of errors.

[0021] In the following description of the present invention, specific descriptions of related known functions or configurations will be omitted if it is determined that such descriptions would unnecessarily obscure the essence of the invention. Furthermore, the terms described below are defined in consideration of their functions within the present invention, and these definitions may vary depending on the intentions or practices of the user or operator. Therefore, such definitions should be based on the content throughout this specification.

[0022] FIG. 2 is a perspective view showing the configuration of an attachment assist device capable of attaching a crack measuring gauge for precise safety diagnosis in the correct position according to the present invention, FIG. 3 is a perspective view showing a reference plate attached to an attachment assist device capable of attaching a crack measuring gauge for precise safety diagnosis in the correct position according to the present invention, FIG. 4 is a perspective view showing the configuration of a reference plate attached to an attachment assist device capable of attaching a crack measuring gauge for precise safety diagnosis in the correct position according to the present invention, and FIG. 5 is a front view of FIG. 3.

[0023] Referring to FIGS. 2 to 5, the attachment assist device (1) capable of attaching a crack measuring gauge for precision safety diagnosis according to the present invention in a fixed position is composed of an upper frame (10), a support member (20), and a lower frame (30).

[0024] First, the upper frame (10) is formed in a rectangular shape with an open center and is equipped with a magnifying glass (11).

[0025] It is preferable that the width of the upper frame (10) be shorter than the length of the reference plate (100) so that the reference plate (100) can be attached.

[0026] The magnifying glass (100) is formed in the shape of a card and bolted to the upper frame (10) so that the reference cross line of the reference plate (100) can be visually checked through the center of the upper frame (10).

[0027] And, the support member (20) is composed of a support (21), a coil spring (23), a ring plate (25), and an attachment member (27).

[0028] The support member (21) is formed with a reduced diameter at its lower end so that a coil spring (23) is connected, and is fixed to the center of each bottom edge of the upper frame. At this time, it is preferable that the movement distance of the support member (21) be formed to be greater than the length at which the reference plate (100) is fixed while overlapping with the numerical plate (200) that is pre-attached to the crack area, and the two support members (21) located in the width direction are directly connected to the reference plate (100), while the two support members (21) located in the length direction move up and down together to perform a guide role.

[0029] The coil spring (23) is coupled to the lower part of the support (21) to provide elasticity to the support (21), that is, to return the support (21) to its original position where pressure is removed after it is lowered. At this time, it is preferable that the compression range of the coil spring (23) be formed to be longer than the length at which the reference plate (100) overlaps and is fixed to the numerical plate (200).

[0030] The ring plate (25) has a larger diameter than the lower part of the support (21) to prevent the support (21) from detaching from the lower frame (30), and an attachment member (27) for attaching the reference plate (100) is provided on the bottom surface of the ring plate (25). At this time, it is preferable that the attachment member (27) be made of a rubber magnet with a relatively weak magnetic force so that the reference plate (100) can be easily detached when attached to the cracked area, and it is preferable that the attachment member (27) be attached only to the bottom surfaces of the two supports (21) located in the width direction among the four supports.

[0031] Meanwhile, as shown in FIG. 4, the reference plate (100) is provided with metal plates (110) at both ends so as to be attached and fixed to the attachment member (27) by magnetic force at a position corresponding to the attachment member (27) on the upper surface, and it is preferable that the metal plates (110) be installed at a position that does not interfere with the central part of the reference cross.

[0032] Furthermore, the lower frame (30) is formed in the shape of a rectangular frame with the same size as the upper frame (10), and a through hole (31) is formed at a position corresponding to the support member (21) so that the lower part of the support member (20) passes through, and a seating groove (33) is formed at the center of each bottom edge of the lower frame (30) so that the reference plate (100) of the crack measuring gauge is attached to the attachment member (27) of the support member (20).

[0033] At this time, it is preferable that the width of the mounting groove (33) be formed larger than the width of the reference plate (100) so that it does not interfere when the reference plate (100) is lowered by the support (21) and attached to the cracked area.

[0034] Meanwhile, a support ledge (35) is formed on the bottom edge of the lower frame (30) by the seating groove (33), and a support (37) is installed on the bottom surface of the support ledge (35).

[0035] Hereinafter, the installation process of an attachment assist device capable of attaching a crack measurement gauge for precision safety diagnosis according to the present invention in the correct position will be explained in detail with reference to the attached drawings.

[0036] FIG. 6 is an operation diagram illustrating the process of installing a reference plate using an attachment assist device capable of attaching a crack measurement gauge for precision safety diagnosis in the correct position according to the present invention.

[0037] First, the worker attaches a numeric gauge (200) to one side of the crack area.

[0038] With the numerical plate (200) attached, the metal plate (110) of the reference plate (100) is attached to the attachment member (27) as shown in FIG. 6 (a). At this time, it is preferable to attach an adhesive such as epoxy to the bottom surface of one end of the reference plate (100).

[0039] In this state, with the attachment auxiliary device (1) capable of attaching the crack measurement gauge for precision safety diagnosis according to the present invention, to which the reference plate (100) is attached, moved to the attachment position, and the lower frame (30) in close contact with the crack area, the position of the lower frame (30) is adjusted so that the cross reference line of the reference plate (100) and the gauge display part of the numerical plate (200) are aligned through the magnifying glass (11) of the upper frame (10).

[0040] When the adjustment is complete, if the worker presses the upper frame (10) downward, the coil spring (23) is compressed and the support (21) is lowered, and together with this, the reference plate (100) is lowered.

[0041] When the reference plate (100) is lowered all the way down and comes into close contact with the upper surface of the numerical plate (200), the adhesive adheres to the cracked area, thereby fixing the reference plate (100) to the cracked area.

[0042] When the reference plate (100) is fixed and the worker relieves the pressure on the upper frame (10), the support (21) is raised by the coil spring (23), and the connection between the metal plate (110) of the reference plate (100) and the attachment member (27) is released, causing the attachment member (27) to rise.

[0043] Afterwards, if necessary, the reference plate (100) is fixed to the cracked area with a piece or the like.

[0044] The present invention may be modified in various ways and may take various forms, and the detailed description of the invention has described only specific embodiments thereof. However, it should be understood that the present invention is not limited to the specific forms mentioned in the detailed description, but rather should be understood to include all variations, equivalents, and substitutions within the spirit and scope of the invention as defined by the appended claims.
