1 is a view showing a multi-functional inspection hammer according to an embodiment of the present invention.

FIG. 2 is a view showing the hammer of FIG. 1 viewed from a different direction.

For reference, assuming that the +Z-axis direction is the upper side of the hammer 100 and the +X-axis direction is the right side of the hammer 100 in FIGS. 1 and 2, the hammer 100 according to the present embodiment in FIGS. 1 and 2 ) Is schematically shown, and a state in which the inclinometer 130 is stacked with respect to the handle 110 and a state in which the gap gauge 150 is inserted into the handle 110 is shown, and in FIG. 2, the hammer of FIG. 100) is seen from the left.

1 and 2, the multifunctional inspection hammer 100 according to an embodiment of the present invention includes a handle 110, a head 120, an inclinometer 130, a magnifying glass 140, and a gap gauge 150. ) Can be included.

The hammer 100 according to the present embodiment may perform various types of inspection on a structure (not shown). In other words, the operator may perform a number of types of inspections on the structure, such as a blow inspection on the structure, an inclination of the structure, and inspection on a gap generated in the structure by using the hammer 100 according to the present embodiment.

The operator may grip the handle 110 in the process of inspecting the structure. A head 120, an inclinometer 130, a magnifying glass 140, and a gap gauge 150 to be described later may be formed on the handle 110.

The handle 110 may be manufactured in the form of a rod having a predetermined length as shown in FIG. 1. In this case, the handle 110 may extend in the vertical direction, that is, in the Z-axis direction as seen in FIG. 1.

For example, the handle 110 may have a rectangular cross-section. However, this is only an example, and the handle 110 may be manufactured in various shapes such as having a circular cross section.

The handle 110 may be made of various materials such as wood or metal such as stainless steel.

A non-slip member (not shown) such as rubber may be formed on all or part of the outer surface of the handle 110. In this case, the handle 110 may be prevented from slipping in a state held by the operator.

The operator may hit the head 120 to the structure in the process of inspecting the structure.

The head 120 is coupled to one end of the handle 110 as shown in FIG. 1. The head 120 may be fixedly coupled to prevent separation from the handle 110 while striking the structure.

For example, the head 120 and the handle 110 may be coupled in a force-fitting manner.

In this case, a concave fitting groove (not shown) is formed in the central portion of the head 120, and one end of the handle 110 facing the head 120 may be fitted into the fitting groove.

In addition, the head and the handle are not shown, but may be combined in a variety of known ways such as bolting.

The head 120 may be made of a metal material such as stainless steel, but is not limited thereto.

The head 120 may extend in a direction perpendicular to the extension direction of the handle 110, for example, in a left-right direction as viewed in FIG. 1, that is, in the X-axis direction.

A first striking part 121 and a second striking part 123 are formed in the head 120. In this case, one end of the head 120, that is, the end facing the -X axis as viewed in FIG. 1 constitutes the first striking part 121, and the other end of the head 120, that is, as viewed in FIG. The end facing the +X-axis direction may constitute the second striking part 123.

The first striking portion 121 may have a shape in which a cross-sectional area is constant or increases from a central portion of the head 120 to an end portion.

As an example, the first striking part 121 may be manufactured in a cylindrical shape with a constant cross-sectional area from the central part of the head 120 to one end as shown in FIGS. 1 and 2.

As another example, although not shown, the first hitting portion may be manufactured in a conical shape in which a cross-sectional area increases from a central portion to one end portion of the head.

In addition, the first hitting unit is not shown, but may be provided in various shapes such as a square pillar shape.

The second striking portion 123 has a shape in which a cross-sectional area decreases from the center portion of the head 120 to the other end portion.

For example, as shown in FIG. 1, the second hitting portion 123 may have a cross-sectional area that decreases from the center to the other end, that is, it may be manufactured in the shape of a sharp cone toward the other end.

In addition, the second hitting unit is not shown, but may be manufactured in various shapes such as a square pyramid shape.

The operator may hit the structure by selecting any one of the first hitting part 121 and the second hitting part 123 in consideration of the impact on the structure.

In more detail, the operator needs to inspect the structure without damaging it. At this time, the worker may hit the structure with the first hitting unit 121. The first hitting part 121 has a relatively wide first hitting surface 121a in contact with the structure, so that the impact is distributed and transmitted to the structure, and the structure can be prevented from being damaged.

Alternatively, the operator needs to inspect a part of the structure by damaging it. At this time, the worker may hit the structure with the second hitting unit 123. The second hitting part 123 has a relatively narrow second hitting surface 123a in contact with the structure, so that the impact on the structure is concentrated and transmitted to a partial area of the structure, and the structure is transmitted by the second hitting surface 123a. Some areas to be hit can be easily damaged.

The operator may use the inclinometer 130 when inspecting the slope of the structure. In this case, the inclinometer 130 may be disposed so that the measurement surface 130a is in contact with the measurement target surface of the structure, for example, an outer surface of a wall or a column, so that the inclination of the structure may be measured.

The inclinometer 130 may be manufactured in a variety of known structures capable of measuring inclination, such as using an angle sensor or a gyro sensor. Detailed description of this will be omitted.

The inclinometer 130 is formed in the central area of the handle 110 as shown in FIGS. 1 and 2. In this case, the inclinometer 130 may be formed to extend in the extending direction of the handle 110 (eg, in the Z-axis direction as seen in FIG. 2) and be coupled to the handle 110.

In this embodiment, the inclinometer 130 may be rotatably coupled to the handle 110.

At this time, the inclinometer 130 normally constitutes a part of the handle 110 as shown in FIGS. 1 and 2, and when measuring the inclination of the structure, the measurement surface 130a rotates toward the structure as shown in FIGS. 3 and 4 can do.

For reference, FIG. 3 is a view showing an unfolded state of the inclinometer of FIG. 1, FIG. 4 is a view showing a view of the inclinometer of FIG. 3 from a different direction, and in FIGS. 3 and 4, the +Z axis is of the hammer 100 It is assumed that the upper side and the +X axis are the right side of the hammer 100, and in FIG. 4, the hammer 100 of FIG. 3 is viewed from the left side.

In more detail, the inclinometer 130 may be superimposed on the handle 110 in normal times, which does not require measuring the inclination of the structure, such as the head 120 hitting the structure. In this case, the inclinometer 130 may be superposed such that its outer surface is parallel to the outer surface of the handle 110 as shown in FIGS. 1 and 2 to form a part of the handle 110.

At this time, the operator can effectively grip the handle 110 without interference from the inclinometer 130 when performing an operation such as hitting the structure using the head 120.

Alternatively, the inclinometer 130 may be unfolded so that the measurement surface 130a faces the structure when measuring the inclination of the structure. In this case, the inclinometer 130 may be unfolded so as to protrude from the handle 110 in a direction perpendicular to the extension direction of the head 120 (eg, the Y-axis direction as seen in FIG. 4) as shown in FIGS. 3 and 4.

In this case, the operator may contact the measurement surface 130a with the measurement target surface of the structure without interference of the head 120 (ie, one of the first and second hitting portions 121 and 123).

For example, the handle 110 may have a concave groove 111 that is concave therein as shown in FIGS. 1 to 4. Inclinometer 130 is coupled to the handle 110 via a hinge shaft (H1) extending in the extending direction of the handle 110 at one side, and the measurement surface 130a formed on the other side opposite to the concave groove 111 ) Can be rotated to be inserted or exposed.

For reference, in FIGS. 1 to 4, the hinge shaft H is exaggerated to distinguish one side and the other side of the inclinometer 130.

In this case, the inclinometer 130 may be rotated so that the measuring surface 130a is inserted into the concave groove 111 as shown in FIGS. 1 and 2 and overlapped with the handle 110. At this time, the LCD-like display (131 in FIG. 4) and the operation button (132 in FIG. 4) formed on the inclinometer 130 are disposed inside the concave groove 111, and external impact in the process of using the hammer 100 It can be prevented from being damaged by the etc.

Alternatively, the inclinometer 130 may be unfolded from the handle 110 by rotating so that the measurement surface 130a is exposed to the outside of the concave groove 111 as shown in FIGS. 3 and 4. The display unit 131 and the operation button 132 formed on the inclinometer 130 are exposed to the outside of the concave groove 111, and the operator operates the inclinometer 130 through the operation button 132 and measured through the display unit 131 You can check the results.

In addition, although the inclinometer is not shown, it can be coupled to the handle in various ways in which the measuring surface can be placed towards the structure.

Meanwhile, the inclinometer 130 may be manufactured in a tapered shape in which the length between both ends in the extension direction decreases toward the bottom surface of the concave groove 111 as viewed in FIG. 1. The inner surface of the concave groove 111 formed in the handle 110 may be manufactured in a tapered shape corresponding to the shape of both ends of the inclinometer 130. In this case, the inclinometer 130 can be easily and effectively inserted when inserted into the concave groove 111.

In the process of inspecting the structure, the operator can accurately and effectively inspect the state of the structure (eg, the surface state of the structure or whether a gap has occurred in the structure) using the magnifying glass 140.

The magnifying glass 140 may be disposed at the other end of the handle 110 as shown in FIGS. 1 and 2. In other words, the magnifying glass 140 may be disposed at the opposite end of the head 120. In this case, the magnifying glass 140 may be prevented from being damaged by an impact generated when the head 120 strikes the structure.

At the other end of the handle 110, a through hole 113 is formed through a direction perpendicular to the extension direction of the handle 110, that is, in the Y-axis direction as seen in FIG. 2, and the through hole 113 has a magnifying glass 140 ) Can be placed.

For example, the magnifying glass 140 may be coupled to the inside of the through hole 113 in a force-fitting manner as shown in FIG. 2. In this case, the magnifying glass 140 may be carried and moved together with the handle 110, and interference with the magnifying glass 140 may be prevented in the process of the operator holding the handle 110.

In addition, the magnifying glass is not shown, but may be coupled to the handle in various ways.

In the process of inspecting the structure, the operator may use the gap gauge 150 to inspect the gap (not shown) generated in the structure. At this time, the gap gauge 150 may be inserted into the gap to measure at least one of a width and a depth of the gap.

The gap gauge 150 may be formed to be retractable at the other end of the handle 110 as shown in FIGS. 1 and 5. For reference, FIG. 5 is a view showing a state in which the gap gauge of FIG. 1 protrudes from the handle, and in FIG. 5, a part of the handle 110 and the gap gauge 150 are enlarged.

For example, at the other end of the handle 110, an insertion groove 115 that is open toward the outside of the other end of the handle 110 is formed as shown in FIGS. 1 and 2, and the gap gauge 150 has a triangular plate structure. It may be manufactured and disposed inside the insertion groove 115.

In this embodiment, the clearance gauge 150 may be rotatably coupled to the handle 110.

In this case, the clearance gauge 150 may be rotatably coupled to the handle 110 via a rotation shaft C supported on the inner wall of the insertion groove 115 as shown in FIGS. 1 and 2.

At this time, the clearance gauge 150 is normally inserted into the insertion groove 115, and can be rotated to protrude outside the insertion groove 115 when inspecting the clearance (see arrow in FIG. 5).

In more detail, the clearance gauge 150 may be inserted into the insertion groove 115 of the handle 110 in normal times, such as the head 120 hitting the structure as shown in FIGS. 1 and 2. In this case, the gap gauge 150 may be prevented from being damaged by an external impact or the like while the head 120 strikes the structure.

Alternatively, the gap gauge 150 may protrude from the handle 110 when measuring at least one of the width and depth of the gap as shown in FIG. 5. In this case, the gap gauge 150 may be inserted into the gap so that at least one of the width and depth of the gap can be measured. Further, since the gap gauge 150 is in a state coupled to the handle 110, the operator can easily insert the gap gauge 150 into the gap by using the gripped handle 110.

A rotation lever 151 may be formed in the gap gauge 150. The rotation lever 151 is provided in a bar shape, one end is fixedly coupled to the gap gauge 150 by welding or the like, and the other end may be extended to be exposed to the outside of the insertion groove 115. In this case, the operator can easily rotate the clearance gauge 150 to be inserted or protruded into the handle 110 by using the rotation lever 151.

In another embodiment, the gap gauge is not shown, but may be coupled to the handle in a sliding manner.

In this case, a sliding groove for guiding the sliding movement in a direction toward the outside of the other end of the handle is formed on the inner wall of the insertion groove of the handle, and the gap gauge may be slidably coupled to the sliding groove.

In addition, although the gap gauge is not shown, it may be manufactured in a variety of forms capable of being withdrawn from the handle or may be coupled to the handle in various ways.

A plurality of scales 150a may be formed on the gap gauge 150 as shown in FIG. 5.

For example, on both sides of the gap gauge 150, scales 150a of scales related to the width of the gap may be formed. In this case, the gap gauge 150 may measure the width of the inserted gap.

As another example, a scale 150a of a scale related to the length of the gap may be formed on both sides of the gap gauge 150. In this case, the gap gauge 150 may measure the depth of the inserted gap.

As another example, a scale 150a for the width of the gap is formed on one side of the gap gauge 150, and a scale 150a for the length of the gap is formed on the other side of the gap gauge 150 Can be. In this case, the gap gauge 150 may selectively measure the width and depth of the inserted gap.

As previously salpinned, the hammer 100 according to the present embodiment includes a head 120 having a first striking part 121 and a second striking part 123 formed on the handle 110 held by the operator, and the inclinometer 130 , The magnifying glass 140 and the gap gauge 150 are formed, so that the operator can perform various inspections on the structure while carrying only the hammer 100 according to the present embodiment. Furthermore, by preventing the operator from carrying a large number of inspection equipment for various inspections of the structure, the operator can easily move during the inspection process of the structure and prevent safety accidents such as falls.

Meanwhile, in another embodiment, as shown in FIG. 6, an auxiliary magnifying glass 160 may be further included.

For reference, FIG. 6 is a view showing a part of a hammer according to another embodiment of the present invention, and in FIG. 6, a part of the handle 110, the gap gauge 150, and the auxiliary magnifying glass 160 are enlarged and shown. , The gap gauge 150 and the auxiliary magnifying glass 160 are shown in a state in which the handle 110 is withdrawn.

The auxiliary magnifying glass 160 may be formed on the handle 110. The auxiliary magnifying glass 160 may be disposed adjacent to the gap gauge 150 of the other end of the handle 110.

In this case, the auxiliary magnifying glass 160 may be formed to be drawn out obliquely with respect to the extending direction of the handle 110. The auxiliary magnifying glass 160 may be pulled out corresponding to the insertion or protrusion state of the gap gauge 150.

In more detail, the auxiliary magnifying glass 160 may protrude obliquely with respect to the handle 110 when the clearance gauge 150 protrudes from the handle 110 as shown in FIG. 6. In this case, the auxiliary magnifying glass 160 is arranged to face the scale of the clearance gauge 150 protruding from the handle 110 (see 150a in FIG. 5), and the operator has the clearance gauge 150 through the auxiliary magnifying glass 160 You can easily check the scale (150a) of.

Alternatively, the auxiliary magnifying glass 160 may be inserted into the handle 110 when the gap gauge 150 is inserted into the handle 110.

For example, the handle 110 may be formed with an auxiliary insertion groove 117 extending obliquely with respect to the extending direction of the handle 110 as shown in FIG. 6. The auxiliary magnifying glass 160 is supported by the support frame 161, and the support frame 161 may be movably coupled to the auxiliary insertion groove 117 in a sliding manner (see arrow in FIG. 6).

In this case, the auxiliary insertion groove 117 may be formed such that a side close to the other end of the handle 110 is opened. The support frame 161 may be inserted into the auxiliary insertion groove 117 through the open side of the auxiliary insertion groove 117 or may protrude from the auxiliary insertion groove 117.

When the auxiliary magnifying glass 160 protrudes from the auxiliary insertion groove 117, the auxiliary magnifying glass 160 may be disposed adjacent to the scale of the clearance gauge 150 protruding from the handle 110 (see 150a of FIG. 5).

A moving knob 163 may be formed on the support frame 161. In this case, the operator may move the support frame 161 inserted into the auxiliary insertion groove 117 through the movement knob 163 to protrude outside the auxiliary insertion groove 117.

This auxiliary magnifying glass 160 may be formed on the handle 110 together with a magnifying glass (see 140 in FIG. 1) or on the handle 110 without a magnifying glass (see 140 in FIG. 1).

Meanwhile, in another embodiment, as shown in FIGS. 7 and 8, the cover member 170 may be coupled to the first hitting portion 121 ′ of the head 120.

For reference, FIG. 7 is a view showing a head of a hammer according to another embodiment of the present invention, FIG. 8 is a view showing a state in which the cover member of FIG. 7 has a cover release operation, and in FIGS. 7 and 8 120) is shown enlarged, and a handle (see 110 in FIG. 1), an inclinometer (see 130 in FIG. 1), a magnifying glass (see 140 in FIG. 1), and a gap gauge (see 150 in FIG. 1) are omitted. 7 and 8, the dotted line represents the outline of the inner surface of the cover member 170, and in FIG. 7 the cover member 170 is shown in the cover operation.

The cover member 170 may be rotatably coupled to the first hitting portion 121 ′. In this case, the cover member 170 is a hinge shaft (H2) on the outer surface of the first hitting portion 121' connected to the first hitting surface 121a' of the first hitting portion 121' as shown in FIG. It can be combined through

The cover member 170 may be rotated to cover the first hitting surface 121a' of the first hitting part 121 ′ according to the strength of the structure hit by the first hitting part 121 ′.

In more detail, the structure (or a partial area of the structure) hit by the first striking part 121 ′ may have relatively low strength, such as a tile. In this case, the cover member 170 may rotate toward the first hitting surface 121a' as shown in FIG. 7 to cover the first hitting surface 121a' (see arrow in FIG. 7). At this time, the cover member 170 buffers the impact of the first hitting part 121 ′ hitting the structure, and the structure with relatively small strength is damaged by the hit of the first hitting part 121 ′ for inspection. Can be prevented more effectively.

Alternatively, the structure (or a partial area of the structure) hit by the first hitting part 121 ′ may have a relatively high strength, such as concrete. In this case, the cover member 170 may rotate to the opposite side of the first hitting surface 121a' as shown in FIG. 8 to release the cover for the first hitting surface 121a' (Fig. 8). See arrow). In this case, the first hitting part 121 ′ may effectively strike a structure having a relatively high strength for inspection.

On the other hand, the structure to which the first hitting part 121 ′ must strike while the cover member 170 is in the cover operation is obtained through a separate experiment or numerical analysis in consideration of the material of the structure and the number of years elapsed, May be provided as a separate table. After comparing the table with the structure to be inspected, the operator may determine a cover operation or a cover release operation of the cover member 170.

Alternatively, the operator may determine the cover operation or the cover release operation of the cover member 170 in consideration of the site situation of the structure.

For example, the cover member 170 may be formed in the form of a hollow pipe with one end open and the other end closed as shown in FIGS. 7 and 8. In this case, the cover member 170 may cover the first hitting portion 121 ′ through one end of the cover member 170 while being in contact with the first hitting surface 121a. Further, as the first striking part 121 ′ is fitted into the cover member 170, the cover member 170 is formed from the first striking part 121 ′ while the first striking part 121 ′ strikes the structure. Breakaway can be prevented.

At this time, the first hitting part 121 ′ is formed in a tapered shape so that a part of one end far from the central part of the head 120 as shown in FIGS. 7 and 8 is reduced in cross-sectional area, and within the other end of the cover member 170. The side view may be formed in a tapered shape corresponding to the shape of one end of the first hitting portion 121 ′. In this case, the cover member 170 can be easily and effectively fitted to the first striking portion 121 ′ during the cover operation.

The cover member 170 may be made of an elastic material such as rubber, but this is only an example, and may be made of various materials capable of buffering the impact of the first hitting portion 121 ′.

In this embodiment, the cover member 170 may be maintained in a state in which the cover is released through the state holding unit 180 as shown in FIG. 8. In this case, the cover member 170 is prevented from rotating while the first striking part 121 ′ strikes the structure, and the first striking part 121 ′ does not interfere with the cover member 170 and effectively manages the structure. You can hit.

In this embodiment, the state holding unit 180 may be manufactured in a groove-protruding manner.

For example, the state holding unit 180 may include a protruding member 181 in which the locking protrusion 183 is formed as shown in FIGS. 7 and 8.

The protruding member 181 may be manufactured in a bar shape that protrudes from the outer surface of the first hitting portion 121 ′. The protruding member 181 may be coupled to the first striking part 121 ′ so as to be adjacent to the coupling portion between the cover member 170 and the first striking part 121 ′ (that is, the hinge shaft H2 ).

A locking protrusion 183 may be formed on a side surface of the protruding member 181. A locking groove 171 through which the locking protrusion 183 is caught may be formed on an outer surface of the cover member 170.

The locking protrusion 183 may be inserted into the locking groove 171 when the cover member 170 is releasing the cover, as shown in FIG. 8. At this time, the rotation of the cover member 170 is stopped, and a state in which the cover release operation is maintained through the coupling between the locking protrusion 183 and the locking groove 171 may be maintained.

Alternatively, the locking protrusion 183 may be separated from the locking groove 171 when the cover member 170 is in a cover operation.
